Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency rescue technology, specifically to a pipe-drafting vehicle and a rescue suction unit. Background Technology
[0002] my country is a country prone to natural disasters and safety accidents. Earthquakes, mudslides, and other geological disasters often result in people being buried alive. During rescue operations, on the one hand, the rescue area is large, the number of trapped people is high, and the burial depth is deep; on the other hand, the rescue window is short, and the environment is complex, with the first 72 hours after the accident being the critical period for saving lives. Furthermore, the rescue vehicles currently available are conventional mechanical equipment, such as excavators, loaders, and bulldozers. While these machines have excavation and clearing capabilities, they are difficult to apply to the complex and harsh environments of areas affected by geological disasters.
[0003] Currently, fire and rescue teams are finding it inefficient to clear debris from above buried individuals, as the debris is difficult to remove quickly. When conventional machinery (excavators, loaders, bulldozers, etc.) is used for close-range rescue, the heavy loads can pose a risk of secondary injury (collision, crushing, etc.) to the buried individuals; therefore, heavy-load machinery is only suitable for the perimeter of the rescue operation. Clearing debris from above buried individuals using hand tools or by hand is labor-intensive and inefficient. Furthermore, secondary collapses are highly likely at accident sites, posing significant safety risks to rescue personnel.
[0004] The inventors discovered that the existing technology has at least the following problems: the existing excavation and suction vehicles used for burial rescue are large vehicle-mounted integrated excavation and suction vehicles, which cannot get close to the rescue site and are not suitable for large-scale geological disaster rescue.

[0113] The following is combined Figures 1 to 20 The technical solutions provided by this invention will be described in more detail below. The descriptions of exemplary embodiments are merely illustrative and are in no way intended to limit this disclosure or its application or use. This disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make this disclosure thorough and complete, and to fully express the scope of this disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0116] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0119] For ease of description. Figure 4 and Figure 5 The length L, width W, and height H of the storage cart 200 are marked. Specifically, the length L of the frame assembly 2 and the storage compartment assembly 3 are the same as the length L of the storage cart 200; the width W of the frame assembly 2 and the storage compartment assembly 3 are the same as the width W of the storage cart 200; and the height H of the frame assembly 2 and the storage compartment assembly 3 are the same as the height H of the storage cart 200.
[0120] Through long-term research, the inventors discovered that landslides caused by geological disasters cover large areas with extremely complex and harsh environments, making it difficult for mechanical equipment to reach the areas where trapped individuals are buried. However, the rescue window is short; the first 72 hours after an accident are critical for saving lives. Relying solely on manual excavation is inefficient, and it's difficult to quickly remove the burying debris above the trapped individuals. Furthermore, the environment at landslide accident sites is extremely complex, and even if small equipment manages to reach the area where trapped individuals are located, it can easily cause secondary injuries. Therefore, this invention proposes the following technical solution to provide power for simultaneous rescue operations at multiple locations, achieving high rescue efficiency and making it possible to use equipment to approach the buried individuals at close range to clear the burying debris.
[0121] This invention provides a rescue suction unit for rescuing people from mud and other buried materials caused by large-scale geological disasters such as earthquakes and mudslides. The rescue suction unit includes a power vehicle 100, a storage vehicle 200, and at least two pipe-hauling vehicles 300.
[0122] The Power Cart 100 serves as the platform for high-performance wind turbines, providing suction power for the unit's operation. The Power Cart 100 utilizes a wheeled chassis, offering high mobility and enabling rapid movement to designated locations. The Storage Cart 200 is an unmanned vehicle.
[0123] See Figures 2 to 4 Some embodiments of the present invention provide a power vehicle 100, including an off-road chassis 101, a subframe 102, a first fan system 103, a second fan system 104, and a fan parallel switching system 106. The off-road chassis 101 includes a first engine, a chassis 1011, and a power take-off (PTO) 1012; the first engine and PTO 1012 are mounted on the chassis 1011; the first engine and PTO 1012 are drivenly connected. The subframe 102 is mounted on the chassis 1011; the first fan system 103 includes a second engine 1031 and a first Roots blower 1033, which are drivenly connected; the second engine 1031 is mounted on the chassis 1011 and is drivenly connected to the first Roots blower 1033. The second fan system 104 includes a second Roots blower 1042; the second Roots blower 1042 is mounted on the subframe 102 and is drivenly connected to the first engine via the PTO 1012. The wind turbine parallel switching system 106 is installed on the off-road chassis 101. The wind turbine parallel switching system 106 includes a first flow channel 1061, a second flow channel 1062, and a switching valve group. The switching valve group is configured to switch the conduction state of the first flow channel 1061 and the second flow channel 1062, so that the wind turbine parallel switching system 106 switches between the following conduction states: the first flow channel 1061 and the second flow channel 1062 are selectively conducted, the first flow channel 1061 is conducted and the inlet of the first flow channel 1061 is connected to the outlet of the second flow channel 1062, and the second flow channel 1062 is conducted and the inlet of the second flow channel 1062 is connected to the outlet of the first air duct.
[0124] The off-road chassis 101 includes a chassis 1011, a first engine (not shown), and a power take-off (PTO) 1012. The first engine powers the entire power vehicle 100 and also provides power to the second Roots blower 1042. The PTO 1012 of the off-road chassis 101 is mounted on the engine flywheel of the chassis 1011, taking power to output power to the second Roots blower 1042 system. The second Roots blower 1042 is directly driven by the engine and engages via an automatic clutch, disengaging or engaging the clutch according to the engine speed. The first Roots blower 1033 is powered by a separately located second engine 1031. The first Roots blower 1033 and the second Roots blower 1042 use different power sources, ensuring that if one power source fails or becomes insufficient, the other can continue operating, guaranteeing the smooth progress of rescue operations. This will be discussed in detail later.
[0125] A mobile, modular vacuum suction device serves as the power source for the unit. It features two operating modes: independent fan operation for multi-point material removal, and combined fan operation for long-distance suction. The modular design of the fan system facilitates expansion of the suction system's capacity, allowing for an increase in the number of fans and access to more work sites. Furthermore, the fan system employs an automatic clutch drive, automatically engaging and disengaging to prevent shock to the engine.
[0126] This power vehicle uses an off-road chassis for transportation and is equipped with multiple fans. It has outstanding functions, is flexible in relocation, and can also work in conjunction with multiple storage vehicles. When one storage vehicle is full, it can switch to another storage vehicle. The full storage vehicle can then travel to the designated location to unload. Compared with the existing integrated excavator suction vehicle, it achieves continuous and efficient suction operations for situations with heavy suction tasks, thus improving on-site operation efficiency.
[0127] The Off-Road Chassis 101 is a vehicle chassis system designed for off-road driving. It features high ground clearance, a robust suspension system, and a high-load-bearing chassis structure, making it more suitable for complex terrains and conditions. The Off-Road Chassis 101 is equipped with a four-wheel drive system, providing better traction and off-road capability.
[0128] The aforementioned advantages make the off-road chassis 101 particularly suitable for environments with poor road conditions. In areas prone to geological disasters, the off-road chassis 101 can also effectively propel the motor vehicle 100 for relocation and transportation, enabling the motor vehicle 100 to better navigate and overcome obstacles such as rivers, steep slopes, and rocks on rugged terrain. Furthermore, the off-road chassis 101 possesses excellent shock absorption performance to reduce vehicle vibrations on uneven surfaces.
[0129] The subframe 102 is bolted to the off-road chassis 101. The subframe 102 employs a frame structure or a plate structure, facilitating the installation of other components. In some embodiments, the subframe 102 is welded from sheet metal or steel pipes and is mounted on top of the off-road chassis 101. The subframe 102 serves to install and support the first fan system 103, the second fan system 104, and the fan parallel switching system 106. The subframe 102 provides sufficient mounting positions for the first fan system 103, the second fan system 104, and the fan parallel switching system 106, making their installation and positioning easier. The subframe 102 enables the first fan system 103, the second fan system 104, and the fan parallel switching system 106 to be mounted together, maintaining the stability and rigidity of the entire vehicle structure by transferring and distributing loads. Furthermore, the subframe 102 has a protective function. In the event of a collision, the subframe 102 absorbs and reduces the bumps and vibrations of the vehicle during driving, and reduces the damage to the vehicle and its occupants by absorbing and dispersing the collision force.
[0130] The first blower system 103 includes a second engine 1031 and a first roots blower 1033. The second engine 1031 and the first roots blower 1033 are modular, meaning they can be installed on the same base. The required number and installation location of the first blower system 103 can be set as needed. Similar to the first engine, the second engine 1031 converts chemical energy into mechanical energy to drive the first roots blower 1033. However, unlike the first engine, the second engine 1031 is only used to drive the first roots blower 1033 and does not need to drive the power vehicle 100. Therefore, a smaller power model can be selected for the second engine 1031. The first roots blower 1033 receives air from the exhaust of the dust collection chamber of the storage vehicle 200 (described later). By drawing exhaust air from the dust collection chamber of the storage vehicle 200, the first roots blower 1033 creates a negative pressure environment in the dust collection chamber, the storage hopper, and the pipeline of the pipe-carrying vehicle 300 connected to the storage hopper.
[0131] The second blower system 104 includes a second Roots blower 1042. The second Roots blower 1042 is also connected to the dust collection chamber of the storage car 200 to achieve suction.
[0132] The first Roots blower 1033 and the second Roots blower 1042 are symmetrically distributed on the two edges of the subframe 102 in the width direction to ensure balanced load distribution on the subframe 102. The first Roots blower 1033 and the second Roots blower 1042 can operate independently or in conjunction. Independent operation means that each of the first Roots blower 1033 and the second Roots blower 1042 is connected to a corresponding storage cart 200, with the first Roots blower 1033 used to suction storage cart 200A and the second Roots blower 1042 used to suction storage cart 200B. Concurrent operation means that the first Roots blower 1033 and the second Roots blower 1042 simultaneously suction storage cart 200A, or simultaneously suction storage cart 200B.
[0133] The fan parallel switching system 106 is installed on both sides of the main beam at the rear end of the off-road chassis 1011 and is fixed with bolts. The fan parallel switching system 106 can effectively realize the switching of the above-mentioned various working states, making the working modes of the power vehicle 100 more diverse. The fan parallel switching system 106 includes a first flow channel 1061, a second flow channel 1062, and a switching valve group. The first flow channel 1061 is connected to one set of storage cars 200, and the second flow channel 1062 is connected to another set of storage cars 200. Through the switching valve group, the first flow channel 1061 and the second flow channel 1062 can be selectively connected, share the air inlet of the first flow channel 1061 and the air inlet of the second flow channel 1062 can be closed, or share the air inlet of the second flow channel 1062 and the air inlet of the first flow channel 1061 can be closed.
[0134] See Figure 4 The first flow channel 1061 specifically includes a first flow inlet 1063, a first flow outlet 1064, and a first pair of interfaces 1061a. The second flow channel 1062 includes a second flow inlet 1065, a second flow outlet 1066, and a second pair of interfaces 1062a; the first pair of interfaces 1061a and the second pair of interfaces 1062a are connected and interconnected; the switching valve group includes: a first solenoid valve 1067, a second solenoid valve 1068, a third solenoid valve 1069, a fourth solenoid valve 10610, and a fifth solenoid valve 10611; the first solenoid valve 1067 is provided at the first flow inlet 1063, the second solenoid valve 1068 is provided at the first flow outlet 1064, the third solenoid valve 1069 is provided at the second flow inlet 1065, and the fourth solenoid valve 10610 is provided at the second flow outlet 1066; the fifth solenoid valve 10611 is provided at either the first pair of interfaces 1061a or the second pair of interfaces 1062a.
[0135] The first flow channel 1061 is a pipe with three openings: a first flow inlet 1063, a first flow outlet 1064, and a first pair of interfaces 1061a. Similarly, the second flow channel 1062 is also a pipe with three openings: a second flow inlet 1065, a second flow outlet 1066, and a second pair of interfaces 1062a. The first pair of interfaces 1061a and the second pair of interfaces 1062a are connected by a flange, thus maintaining communication between the first flow channel 1061 and the second flow channel 1062.
[0136] Of course, casting or other methods can also be used to process the first flow channel 1061 and the second flow channel 1062 into one piece.
[0137] The first outlet 1064 of the first flow channel 1061 is connected to the air inlet of the first Roots blower 1033, and the second outlet 1066 of the second flow channel 1062 is connected to the air inlet of the second Roots blower 1042.
[0138] The switching valve assembly includes a first solenoid valve 1067, a second solenoid valve 1068, a third solenoid valve 1069, a fourth solenoid valve 10610, and a fifth solenoid valve 10611. A solenoid valve is arranged in each of the following ports: first inlet 1063, first outlet 1064, second inlet 1065, second outlet 1066, and either the first pair of ports 1061a or the second pair of ports 1062a. Therefore, each of these five ports can be individually controlled to open or close. Consequently, the connection configuration between the first flow channel 1061 and the second flow channel 1062 can be varied.
[0139] The first configuration involves the first inlet 1063 and the first outlet 1064 being connected, and both the second inlet 1065 and the second outlet 1066 being connected, while either the first pair of interfaces 1061a or the second pair of interfaces 1062a are disconnected. This configuration applies to situations where the first Roots blower 1033 is used to suction the storage cart 200A, and the second Roots blower 1042 is used to suction the storage cart 200B. In other words, the first Roots blower 1033 and the second Roots blower 1042 operate independently.
[0140] The second configuration involves the first inlet 1063 being simultaneously connected to both the first outlet 1064 and the second outlet 1066, and the first pair of interfaces 1061a (or the second pair of interfaces 1062a) also being connected, while the second inlet 1065 is disconnected. This configuration applies when the first Roots blower 1033 and the second Roots blower 1042 are simultaneously pumping material from the storage car 200A. The first Roots blower 1033 and the second Roots blower 1042 work in coordination.
[0141] The third method differs from the second in that the connection times of the first inlet 1063, the first outlet 1064, and the second outlet 1066 are different. Initially, during suction, the first inlet 1063 is directly connected to the first outlet 1064, and the first Roots blower 1033 suctions the storage car 200A. During the suction operation, the suction status is monitored in real time. If the power is insufficient, the first inlet 1063 is then connected to the second outlet 1066, and the second Roots blower 1042 provides additional suction power, resulting in more sufficient suction power for the storage car 200A.
[0142] The fourth scenario involves the second inlet 1063 being simultaneously connected to both the first outlet 1064 and the second outlet 1066, and either the first pair of interfaces 1061a or the second pair of interfaces 1062a also being connected, while the first inlet 1063 is disconnected. This scenario applies when the first Roots blower 1033 and the second Roots blower 1042 are simultaneously suctioning the storage car 200B. The first Roots blower 1033 and the second Roots blower 1042 work in coordination.
[0143] The fifth method differs from the fourth in that the connection times between the second inlet 1063 and the first outlet 1064, and the second outlet 1066, are different. Initially, during suction, the second inlet 1063 is directly connected to the second outlet 1066, and the second Roots blower 1042 suctions the storage cart 200B. During the suction operation, the suction status is monitored in real time. If the power is insufficient, the second inlet 1063 is then connected to the first outlet 1064, and the first Roots blower 1033 provides additional suction power, resulting in more sufficient suction power for the storage cart 200B.
[0144] In some embodiments, at least one of the first solenoid valve 1067, the second solenoid valve 1068, the third solenoid valve 1069, the fourth solenoid valve 10610, and the fifth solenoid valve 10611 is a butterfly valve, and all of them may be butterfly valves. Butterfly valves offer high control precision and are easy to install. The opening and closing times of each solenoid valve are independently controlled, allowing the power vehicle to provide a more flexible power mode for the suction operations of the storage car and the pipe-hauling car.
[0145] See also Figure 3 and Figure 4 In some embodiments, the power vehicle also includes a first air supply assembly 1034, which is connected to the air inlet of the first Roots blower 1033.
[0146] The first make-up air assembly 1034 is used to reduce the operating temperature of the first Roots blower 1033. It includes a first make-up air duct, interfaces, etc. The first make-up air duct is connected to the outside atmosphere. When the first Roots blower 1033 draws air from the dust collection chamber of the storage car, outside air also enters the first Roots blower 1033 through the first make-up air duct of the first make-up air assembly 1034. The first make-up air assembly 1034 provides additional airflow to the first Roots blower 1033 to meet ventilation requirements under different environmental scenarios and needs. The make-up air volume can be set to be adjustable; the amount of make-up air can be adjusted by adjusting the flow area of the first make-up air duct.
[0147] The power vehicle provided by the above technical solution provides suction power and employs a multi-Roots blower combined control mode to provide suction power for the storage truck operation. The first and second Roots blowers switch between independent and combined operation modes according to operational needs, allowing for both individual and parallel operation, providing strong long-range suction capabilities and maximizing rescue efficiency. During on-site rescue, the power vehicle is deployed around the perimeter of the rescue area to provide remote suction power, connecting to the unit's storage truck and other equipment via hoses.
[0148] In some embodiments, the power vehicle further includes a first muffler, which is installed upstream of the air inlet of the first Roots blower 1033 to reduce noise in the first Roots blower 1033.
[0149] The first silencer is used to reduce the noise of the first Roots blower 1033. There are two first silencers 105a: a first exhaust silencer 1052 and a first intake silencer 1054, which are fixedly connected by bolts and serve as the air inlet and outlet silencers for the first Roots blower 1033, respectively. The first silencer consists of an intake section, a silencing section, and an exhaust section. The intake section guides the airflow into the first silencer, and the silencing section is the main noise reduction area, absorbing, scattering, and reflecting noise through internal sound-absorbing materials or other structures, thereby reducing the propagation and impact of noise. The exhaust section releases the noise-reduced airflow into the external environment. The structure and materials of the first silencer have sound insulation effects, preventing noise from propagating through walls or other obstacles; the first silencer also absorbs some vibration energy, reducing the vibration and noise of the first Roots blower 1033. Reducing noise can improve the working environment and increase employee work efficiency and comfort.
[0150] See also Figure 3 and Figure 4 In some embodiments, the power vehicle also includes a second air supply assembly 1043, which is connected to the air inlet of the second Roots blower 1042.
[0151] The second make-up air assembly 1043 supplies additional make-up air to the second Roots blower 1042. It includes a second make-up air duct, interfaces, etc. The second make-up air duct is connected to the outside atmosphere. When the second Roots blower 1042 draws air from the dust collection chamber of the storage car, outside air also enters the second Roots blower 1042 through the second make-up air duct of the second make-up air assembly 1043. The second make-up air assembly 1043 provides additional airflow to the second Roots blower 1042 to meet ventilation requirements under different environmental scenarios and needs. The make-up air volume can be set to be adjustable; the amount of make-up air can be adjusted by adjusting the flow area of the second make-up air duct.
[0152] In some embodiments, the power vehicle further includes a second muffler, which is installed upstream of the air inlet of the second Roots blower 1042 to reduce noise in the second Roots blower 1042.
[0153] The second muffler 105b is used to reduce the noise of the second Roots blower 1042. There are two second mufflers 105b: a second exhaust muffler 1053 and a second intake muffler 1054, which are bolted together and serve as the air inlet and outlet mufflers of the second Roots blower 1042, respectively. The second exhaust muffler 1053 and the second intake muffler 1054, as well as the first exhaust muffler 1052 and the first intake muffler 1054 mentioned above, are all mounted to the bracket 1051 with clamps. The bracket 5101 is mounted to the subframe 102.
[0154] The second silencer 105b consists of an inlet section, a silencing section, and an outlet section. The inlet section guides airflow into the second silencer 105b, while the silencing section is the main noise reduction area. It absorbs, scatters, and reflects noise through internal sound-absorbing materials or other structures, thereby reducing noise propagation and impact. The outlet section releases the reduced airflow into the external environment. The structure and materials of the second silencer provide sound insulation, preventing noise from propagating through walls or other obstacles. The second silencer also absorbs some vibration energy, reducing the vibration and noise of the second Roots blower 1042. Reduced noise improves the working environment and increases employee efficiency and comfort.
[0155] In some embodiments, the power vehicle further includes a control system, which includes a controller, a display, and a pressure detection element; the pressure detection element is installed at the air inlet of the first Roots blower 1033 and the second Roots blower 1042 to detect the air inlet pressure of the first Roots blower 1033 and the second Roots blower 1042.
[0156] See Figure 5The power vehicle also includes a power vehicle control system 107, which includes a controller, a display, a first pressure detection element 1071, and a second pressure detection element 1072. The first pressure detection element 1071 is installed at the air inlet of the first Roots blower 1033 to detect the air inlet pressure of the first Roots blower 1033; the second pressure detection element 1072 is installed at the air inlet of the second Roots blower 1042 to detect the air inlet pressure of the second Roots blower 1042.
[0157] The following describes the power path and air intake path of the first Roots blower 1033 and the second Roots blower 1042.
[0158] The first blower system 103 mainly includes a second engine 1031, a clutch assembly 1032, a first Roots blower 1033, a first air supply assembly 1034, a first air inlet adapter structure 1035, a first safety filter cartridge 1036, a first negative pressure safety valve 1037, and a first unloading valve 1038, such as Figure 2 and Figure 3 As shown, the first air inlet adapter is a bent duct.
[0159] In the first blower system 103, the second engine 1031 and the first Roots blower 1033 are connected by a clutch assembly 1032. The first air supply assembly 1034 connects to the air supply ports at both ends of the first Roots blower 1033. The air outlet of the first safety filter cartridge 1036 and the air inlet of the first Roots blower 1033 are connected by a first air inlet adapter structure 1035. The first negative pressure safety valve 1037 and the first unloading valve 1038 are respectively installed on the first safety filter cartridge 1036. The first blower system 103 is modularly designed and is installed as a whole on the subframe 102. It can be used independently, or the number of matching components can be increased according to the dimensions of the chassis 1011 to increase the number of suction operation points.
[0160] The second fan system 104 mainly includes a transmission system 1041, a second Roots blower 1042, a second make-up air assembly 1043, a second air inlet adapter structure 1044, a second safety filter cartridge 1045, a first negative pressure safety valve 1037, and a second unloading valve 1047. The transmission system 1041 in the second fan system 104 mainly includes a first drive shaft 10411, a second drive shaft 10412, a drive bearing housing 10413, a belt 10414, and a fan pulley 10415.
[0161] In the second blower system 104, the transmission system 1041 is connected at one end to the power take-off 1012 in the off-road chassis 101, and at the other end to the second Roots blower 1042. The second air supply assembly 1043 is connected to the air supply ports at both ends of the second Roots blower 1042. The air outlet of the second safety filter cartridge 1045 and the air inlet of the second Roots blower 1042 are connected by the second air inlet adapter structure 1044. The second negative pressure safety valve 1046 and the second unloading valve 1047 are respectively installed on the second safety filter cartridge 1045.
[0162] During the suction process, when the first pressure detection element 1071 detects that the negative pressure in the pipeline is too high and exceeds the set value, in order to prevent the system structure from being damaged by excessive pressure for a long time, the controller sends a control signal to open the first unloading valve 1038 for a duration of, for example, 3 seconds, so that external air is drawn into the fan inlet pipe, and the system working pressure is limited to a certain range.
[0163] Similarly, when the second pressure detection element 1072 detects that the pipeline negative pressure exceeds the set value, the controller sends a control signal to open the second unloading valve 1047 and keep it open for a duration of, for example, 3 seconds, allowing external air to be drawn into the fan inlet pipe and limiting the system working pressure within a certain range. The maximum operating negative pressure can be set on the display and can be set to different values depending on different situations.
[0164] The material storage vehicle 200 is self-powered and uses a tracked chassis for movement, giving it strong obstacle-crossing ability. It can be remotely controlled to move to the designated rescue location.
[0165] The pipe-tow truck 300 is also an unmanned vehicle. It is equipped with its own battery and can move on tracks. It serves as the "hands" and "eyes" of rescuers, and can observe the rescue site in real time through cameras.
[0166] The power unit 100 provides the suction power, which can be provided by one or two Roots blowers, allowing the landfill material to be sucked into the pipe-hauling truck 300 and then into the storage truck 200. The suction power required by the pipe-hauling truck 300 comes from the power unit 100. The pipe-hauling truck 300 does not need to have a storage chamber; the landfill material sucked in by the pipe-hauling truck 300 is directly sucked into the storage truck 200 and stored there. Therefore, the size of the pipe-hauling truck 300 can be designed to be sufficiently lightweight and compact, allowing it to be easily moved to areas near the landfilled personnel for rapid suction and removal of the landfill material.
[0167] Each power vehicle 100 is connected to at least two storage vehicles 200, meaning that one power vehicle 100 can simultaneously provide suction power to two or more storage vehicles 200. The operation of each storage vehicle 200 is independently controlled; they can work individually or multiple storage vehicles 200 can work simultaneously. This variety of operating modes better meets the needs of different scenarios.
[0168] Specifically, the power vehicle 100 is connected to the hopper 30 of the storage vehicle 200 to provide suction power to the hopper 30. The hopper 30 of the storage vehicle 200 is connected to the suction pipe 30224 of the pipe-hauling vehicle 300. Under the negative pressure provided by the power vehicle 100, the suction pipe 30224 of the pipe-hauling vehicle 300 is also under negative pressure, allowing the buried material at the accident site to be quickly sucked into the suction pipe 30224. Then, under the action of its own gravity, the buried material is stored in the hopper 30 of the storage vehicle 200. It should be noted that liquid may also be sucked up simultaneously when suctioning the buried material. The liquid may or may not be stored in the storage vehicle 200. If it is not necessary to store it in the storage vehicle 200, the drain port 38 of the storage vehicle 200 can be opened to drain the liquid. If the liquid needs to be stored in the storage cart 200, the storage cart 200 can be moved to the sewage discharge area, and then the sewage discharge port 38 can be opened to discharge the liquid.
[0169] Each storage truck 200 is connected to at least two pipe-hauling trucks 300. The storage trucks 200 and pipe-hauling trucks 300 are connected via pipelines. Each pipe-hauling truck 300 corresponds one-to-one with and is connected to the inlet 303 of the storage compartment assembly 3 of the storage truck 200 (described later). The length of the pipeline corresponding to each pipe-hauling truck 300 can be flexibly set as needed to facilitate rescue operations at different locations. Each pipeline adopts a quick-connect fitting design, facilitating the flexible replacement of pipelines of different lengths. All pipe-hauling trucks 300 can work simultaneously, jointly transferring the pumped buried material to the same storage truck 200. This enables multi-pipeline, multi-point coordinated long-distance pumping operations, greatly improving rescue efficiency.
[0170] The storage truck 200 is connected to each pipe-hauling truck 300 via a second connecting pipe 500, instead of using a screw conveyor or conveyor belt. This reduces the requirements on the shape of the buried material; any buried material that can be sucked into the pipe can be transported to the storage truck 200 for storage. Furthermore, the buried material entering the storage truck 200 settles directly under its own gravity, preventing it from accumulating in one place and allowing it to cover all areas of the storage truck 200's hopper 31, thus improving the storage efficiency of the storage truck 200. Material can settle without human intervention, eliminating manual handling steps, making the operation more automated and efficient, and more suitable for applications in geological disaster rescue areas with extremely short rescue windows. On the other hand, the lightweight pipe makes it easier for the pipe-hauling truck 300 to move it. With the same load-bearing capacity, the pipe can be longer than other conveying methods, making the pipe-hauling truck 300 more suitable for entering distant, inaccessible hazardous areas.
[0171] The power vehicle 100 is equipped with at least one Roots blower. When a single Roots blower is operating, the air inlet port of the power vehicle 100 is connected to the rotary flange pipe interface of the piping assembly 102 of the storage vehicle 200 via the first connecting pipe 400, thus connecting the power vehicle 100 and the storage vehicle 200. Opening the inlet gate valve of one storage vehicle 200 and connecting the gate valve to the pipe interface of the pipe trailer 300 via a pipe allows for a 1+1+1 operation. Opening two inlet gate valves and connecting two pipe trailers 300 allows for a 1+1+2 operation mode. Opening three inlet gate valves and connecting three pipe trailers 300 allows for a 1+1+3 operation mode. If two blowers on the power vehicle 100 are operating simultaneously, the two blowers can provide power to two storage vehicles 200, and similarly, a maximum of a 1+2+6 operation mode can be achieved.
[0172] The rescue suction unit proposed in the above technical solution adopts a 1+2+N split-type combination design, where 1 represents one power vehicle 100, 2 represents two storage vehicles 200, and N represents N pipe-hauling vehicles 300. The number of N is greater than or equal to 4. The storage vehicle 200 is used to connect the power vehicle 100 and the pipe-hauling vehicles 300 in the entire unit. After the power vehicle 100, storage vehicle 200, and pipe-hauling vehicle 300 are all in place, high negative pressure hoses are used to connect the power vehicle 100 to the storage vehicle 200, and the storage vehicle 200 to the pipe-hauling vehicle 300 using quick-connect couplings. This saves preparation time for rescue and strives to complete the pre-rescue preparation work as quickly as possible, ensuring that the unit can be put into rescue work. Here, "all in place" means that the rescue can be carried out as soon as the power vehicle 100, at least one storage vehicle 200, and at least one pipe-hauling vehicle 300 are in place. For areas that are inaccessible to personnel, the pipelines between the various vehicles can be connected first, and then the vehicles can be moved to the designated rescue location.
[0173] The rescue suction unit provided by the above technical solution consists of a power vehicle 100, a storage vehicle 200, and a pipe-hauling vehicle 300. The entire unit is highly modular, with each sub-vehicle having a prominent main function. The sub-vehicles are connected by pipelines, enabling simultaneous operation at multiple points and meeting the requirements for speed and safety in rescue operations. The storage vehicle 200 adopts an automatically controlled multi-inlet structure 303, a zoned air duct guiding device, and a dust removal and hopper 31 arrangement, effectively achieving gas-solid separation and improving the efficiency of suction and removal of buried materials.
[0174] See Figure 5 and Figure 6 The storage cart 200 stores the material sucked in by the suction end. Utilizing the principle of inertial settling, the material settles within the hopper. The airflow, after being filtered by a dust removal device, enters the fan of the power vehicle 100. The specific implementation of the storage cart 200 is described in detail below.
[0175] This invention provides a storage cart 200, including a traveling mechanism 1, a frame assembly 2, and a storage bin assembly 3. The frame assembly 2 is mounted on the traveling mechanism 1. The storage bin assembly 3 is mounted on the frame assembly 2; the storage bin assembly 3 includes a bin body 30, a bin cover 33, and at least two inlet control components 35; the bin body 30 is provided with a discharge port 301, an air outlet 304, and at least two inlets 303, and the bin cover 33 is closable and installable at the discharge port 301. The following description uses three inlets 303 as an example; however, more inlets 303 can be provided if needed. Each inlet 303 is equipped with an inlet control component 35 for controlling the opening and closing of the inlet 303. The inlet control component 35 can be a pneumatically or electrically controlled valve.
[0176] The aforementioned technical solution provides a storage vehicle 200 for collecting and transferring buried materials. It includes a walking mechanism, a frame assembly, and a storage bin assembly. The storage bin assembly receives buried materials transported by the upstream pipe-hauling vehicle 300. The storage bin assembly has at least two inlets, each connected to a pipe-hauling vehicle 300. Pipe-hauling vehicles 300 connected to the same storage bin assembly of the same storage vehicle 200 can be located at different work positions, enabling simultaneous multi-point rescue and significantly improving rescue efficiency. Since the pipe-hauling vehicle 300 directly transports the buried materials to the storage vehicle 200, it does not require a storage chamber. Therefore, the structure of the pipe-hauling vehicle 300 can be very compact and lightweight, making operation more flexible. It can also be configured as an unmanned vehicle, protecting the safety of rescue personnel. The compact, lightweight, and flexible pipe-laying vehicle 300 can more easily approach collapsed areas, dangerous areas inaccessible to personnel, and areas buried by soil in geological disasters. This makes mechanical rescue possible, greatly increases the likelihood of rescue, and allows more rescue operations to be completed within the rescue window.
[0177] The traveling mechanism 1 is used to move and relocate the storage vehicle 200. The environment in the soil burial accident area is extremely complex and difficult to navigate. The traveling mechanism 1 can be a tracked traveling mechanism 1 to increase the contact area between the traveling mechanism 1 and the ground, so that the storage vehicle 200 can travel on various uneven and muddy roads.
[0178] The traveling mechanism 1 includes two tracks, which are arranged on the two edges of the bottom width of the chassis assembly 2. The two tracks have strong load-bearing capacity, high structural stability, flexible operation, and high mobility, effectively supporting the chassis assembly 2. This allows for a larger volume of the storage vehicle 200's bin 30, enabling it to carry more buried material at once and thus allowing for a larger bin volume. This facilitates the storage and transfer of buried materials, effectively improving the unit's rescue efficiency.
[0179] The chassis assembly 2 supports the storage compartment assembly 3. The structure of the chassis assembly 2 can be designed to be as lightweight as possible to achieve product weight reduction, so that the storage compartment assembly 3 can carry more buried materials without changing the track load capacity.
[0180] See Figures 5 to 8 The storage silo assembly 3 includes a silo body 30, a silo cover 33, and at least two inlet control components 35. The silo body 30 is used for storage, and the silo cover 33 is used to open and close the silo body 30. When the silo cover 33 is closed, landfill material can enter the silo body 30 via a pipe-haul truck 300 and the inlet control components 35. When the silo cover 33 is open, the landfill material stored in the silo body 30 is discharged to the outside or into other waste transfer vehicles.
[0181] The storage bin assembly 3 and the frame assembly 2 are connected by a pin at the rear rotation hinge point. One end of the luffing cylinder (not shown) is connected to the middle crossbeam of the frame assembly 2 by a pin, and the other end is connected to the lifting hinge point at the bottom of the storage bin assembly 3. By extending and retracting the luffing cylinder, the storage bin assembly 3 is lifted away from the frame assembly 2, so that the storage bin assembly 3 and the frame assembly 2 are arranged at an angle, with the front end of the storage bin assembly 3 higher and the rear end lower. The discharge port 301 of the storage bin assembly 3 is located at the rear end. Under its own gravity, the material in the storage bin assembly 3 can be discharged.
[0182] The silo body 30 includes a discharge port 301, an air outlet 304, and at least two feed inlets 303. The feed inlets 303 are used to transport the buried material from the upstream pipeline into the silo body 30. The opening and closing operations of each feed inlet 303 are independent and do not affect each other. Each feed inlet 303 can be opened simultaneously or intermittently. Taking each feed pipe connected to a separate pipe-hauling truck 300 as an example, the feed inlet 303 corresponding to the pipe-hauling truck 300 that arrives at its destination first can be opened first, and the pipe-hauling truck 300 can be started first. The feed inlet 303 corresponding to the pipe-hauling truck 300 that arrives later can be opened later. This enables automatic control of each feed inlet 303, achieving multi-point suction rescue and non-stop operation, resulting in high rescue efficiency.
[0183] Landfill materials are generally solid, but in situations such as floods, they may also contain large amounts of liquid. In the case of the pipe-lift truck 300, both liquid and solid materials are absorbed into the pipes of the pipe-lift truck 300 and then transported to the hopper 30 of the storage truck 200. Furthermore, a large amount of polluted air is generated during the absorption process.
[0184] The silo 30 can process materials in different forms—solid, liquid, and gaseous—separately. During operation, following the flow of the landfill material, the entire material first enters the silo 30 through the inlet 303. Then, depending on the properties of the landfill material, three processing methods are employed:
[0185] In the first method, the solids will automatically settle to the bottom of the hopper 30 under their own weight. After the hopper 30 is full of solids, the discharge port 301 is opened to discharge the solids from the hopper 30.
[0186] The second method involves the liquid being drawn from the pipe-carrying truck 300 into the storage truck 200. Since the storage truck 200 is a certain distance from the pipe-carrying truck 300, such as 140 to 160 meters, the liquid can be discharged on-site at the location of the storage truck 200: that is, the drain valve 334 of the silo 30 is opened to discharge the liquid.
[0187] Thirdly, the gas can be purified and discharged into the atmosphere or transported to other pneumatic components.
[0188] To facilitate the processing of various materials, in some embodiments, the silo body 30 includes a partition 36 disposed inside the silo body 30. The partition 36 is, for example, a plate, formed by assembling one or more plates. The partition 36 divides the silo body 30 into a material silo 31 and a dust removal silo 32. The partition 36 is provided with a connecting port 3162. Each feed inlet 303 is disposed in the material silo 31, specifically on the rear wall of the material silo 31. An air outlet 304 is disposed in the dust removal silo 32. The material silo 31 and the dust removal silo 32 share a discharge port 301. The material silo 31 is used to store solids, while the dust removal silo 32 is used to remove dust from the gas drawn into the material silo 31. When the silo cover 33 is opened, the solid material in the material silo 31 and the dust filtered out by the dust removal silo 32 can be discharged simultaneously.
[0189] See Figure 5 In some embodiments, there are two partitions 36, which are parallel to the length of the storage cart 200. Along the width W of the storage cart 200, the silo body 30 is divided into three parts: two dust collection silos 32 located on either side of the width, and a material silo 31 located between the two dust collection silos 32. The silo body 30 adopts a partitioned design, allowing for a rational layout of dust collection and material storage functions. The material silo 31 and dust collection silos 32 are arranged along the width of the storage cart 200, rather than along its length, allowing gas to enter the various areas of the dust collection silos 32 more evenly. This ensures that each dust filter 323 within the dust collection silo 32 receives air more evenly and is fully utilized, significantly improving dust collection efficiency. If the silo 31 and the dust removal silo 32 are arranged along the length of the storage car 200, the airflow enters the silo 31 from the rear and needs to flow through the entire silo 31 before reaching the dust removal silo 32 at the front. After entering the dust removal silo 32, the airflow first contacts the dust filter 323 closest to the silo 31, which may cause the dust filter 323 to be blocked quickly. However, the utilization rate of the dust filters 323 far away from the silo 31 is very poor.
[0190] As described above, the storage assembly 3 is divided into three parts: left, middle, and right. The middle part is the material hopper 31, and the two sides are dust removal hoppers 32. The two dust removal hoppers 32 are arranged on both sides of the material hopper 31, and the material hopper 31 and the dust removal hoppers 32 are connected by a flow guiding assembly 37. The flow guiding assembly 37 includes a first air duct flow guiding device 316 and a second air duct flow guiding device 317. One dust removal hopper 32 is connected to the material hopper 31 through the first air duct flow guiding device 316, and the other dust removal hopper 32 is connected to the material hopper 31 through the second air duct flow guiding device 317.
[0191] The specific implementation of hopper 31 is described below.
[0192] See Figure 6 The silo 31 is equipped with various inlets 303. The dust collector 32 and the silo 31 share a discharge port 301. The discharge port 301 discharges both solids from the silo 31 and dust filtered from the dust collector 32. The width of the discharge port 301 is approximately the same as the combined width of the dust collector 32 and the silo 31. The discharge port 301 can be located in the lower half of the tail section of the silo 31. The height of the discharge port 301 is approximately half the height of the silo 31, and the bottom of the discharge port 301 is flush with the bottom edge of the silo 31. The silo cover 33, used to close the discharge port 301, opens by a top-screwing mechanism, with an angle of, for example, 85° to 95°. Specifically, the top of the cover 33 is rotatably connected to the silo 31. This method maximizes the opening of the cover 33, allowing solids and liquids in the silo 31 to be discharged quickly, meeting the requirements of a very short rescue window.
[0193] Based on the principle of negative pressure suction, as long as the inlet 303 is opened, material will continuously enter the silo 31 through the suction pipe 30224 connected to the gate valve at the rear of the silo 31. The drain valve 334 can discharge the suctioned liquid material, ensuring that the silo 31 stores as much solid material as possible and maximizes the utilization of the silo 31 space.
[0194] See Figure 6 A material level detection device 51 is located at the top center of the hopper 313 to monitor the material status in real time. When the material level detection switch 51 detects that the hopper 31 is full, the storage vehicle control system 5 will control the gate valve 311, 312, or 313 at the corresponding feed inlet 303 to close. The lifting and unloading operation will then begin. For safety reasons, the hopper cover 33 must be opened to approximately 90° before the hopper 313 is allowed to tilt and lift for unloading.
[0195] During unloading, the silo cover locking cylinder connects the pull rod assembly 333 and the silo cover pressing mechanism 332. As the silo cover locking cylinder retracts, the pull rod assembly 333 first disengages the locking device 332 from the locking ring (not shown). When the locking device 332 rotates to its maximum 30°, the silo cover locking cylinder retracts further, and the silo cover 33 rotates open 90° under the action of the locking cylinder. The entire silo cover 33 is then opened, and the unloading operation begins. The pull rod assembly 333 allows for adjustable length; the upper and lower threads of the pull rod are opposite, and rotating the pull rod extends or shortens it, ensuring that the silo cover 33 remains pressed down at all times.
[0196] The aforementioned cover drive mechanism 34 uses a single cover locking cylinder to achieve the interlocking action of opening / closing the cover 33 and locking the sealed cover 33. It has an error prevention function. During the operation of the cover locking cylinder, the locking device 332 must be released before the cover 33 can be opened. This prevents the cover from being opened without releasing the cover 33, thus avoiding misoperation.
[0197] After unloading is completed, the silo cover locking cylinder extends, and the silo cover 33 closes first. The cylinder continues to extend, pushing the locking device 332 connected to the pull rod assembly 333 to further press the silo cover 33, ensuring the sealing effect of the silo cover 33.
[0198] See also Figure 6 To facilitate control of the opening and closing of the compartment cover 33, in some embodiments, the storage compartment assembly 3 further includes a compartment cover drive mechanism 34. The compartment cover drive mechanism 34 is mounted on the storage compartment assembly 3 and is driven by the compartment cover 33 to drive the compartment cover 33 to open and close. The compartment cover drive mechanism 34 can be driven pneumatically or hydraulically. The compartment cover drive mechanism 34 is configured to rotate the compartment cover 33 by 85° to 95°.
[0199] See also Figure 6 In some embodiments, the silo cover driving mechanism 34 includes a silo cover locking cylinder, a pull rod assembly 333, and a silo cover pressing mechanism 332. The silo cover locking cylinder includes a cylinder barrel and a piston; one of the cylinder barrel and the piston is rotatably connected to the silo body 30. One end of the pull rod assembly 333 is rotatably connected to the other of the cylinder barrel and the piston. The silo cover pressing mechanism 332 is connected to the other end of the pull rod assembly 333 to drive the silo cover 33 to open and close as the silo cover locking cylinder extends and retracts; the silo cover pressing mechanism 332 is in a sealing fit with the discharge port 301 of the silo 31.
[0200] In some embodiments, the storage vehicle 200 further includes a storage vehicle hydraulic system 9 and an oil tank assembly 8. The storage vehicle hydraulic system 9 is in fluid communication with the silo cover locking cylinder to realize the extension and retraction control of the silo cover locking cylinder. The oil tank assembly 8 provides hydraulic oil to the entire storage vehicle hydraulic system 9. The storage vehicle hydraulic system 9 provides hydraulic power to various functional components to realize the functions of the storage vehicle chassis travel, unloading control, air compressor, and generator.
[0201] The silo cover clamping mechanism 332 and the discharge port 301 of the silo 31 achieve a sealed fit with the following structure: In some embodiments, the silo cover clamping mechanism 332 includes a mounting component and a locking hook. The mounting component is connected to the other end of the second pull rod; the locking hook is mounted on the mounting component; the mounting component can be a plate or a rod. The silo body 30 is correspondingly provided with a locking ring, which can engage and unlock with the locking hook. There are multiple locking rings and locking hooks, arranged in a one-to-one correspondence. The locking ring can be provided with multiple engagement positions, and the locking hook can be hooked at different positions as needed to meet different sealing requirements.
[0202] The hopper cover clamping mechanism 332 also includes a sealing element, which is installed on the mounting component or directly on the edge of the hopper cover 33. Sealing elements are provided in areas where the hopper cover 33 may come into contact with the discharge port 301. The sealing element can be a sealing strip, which forms a sealing fit with the discharge port 301.
[0203] After a period of use, the sealing strip may deform or fail, resulting in a poorer seal between the sealing strip and the discharge port 301. To adjust the sealing effect of the sealing strip, in some embodiments, the pull rod assembly 333 is constructed to be telescopic to adjust the clamping force between the clamping cover 33 and the hopper 31. When the sealing strip fails or deforms, the length of the pull rod assembly 333 is increased to ensure a reliable seal between the hopper cover 33 and the hopper 31. This compensates for the problem of the hopper cover 33 not being able to be clamped due to changes in the rebound amount of the seal, ensuring that the hopper cover 33 is always in a clamped and sealed state, thus improving operational safety and practicality.
[0204] In some embodiments, the pull rod assembly 333 includes a sleeve, a first pull rod, and a second pull rod. The sleeve includes a communicating first threaded hole and a second threaded hole. One end of the first pull rod is provided with a first thread, which engages with the first threaded hole; the other end of the first pull rod is rotatably connected to another of the cylinder and piston. One end of the second pull rod is provided with a second thread, which engages with the second threaded hole; the other end of the second pull rod is connected to the cover clamping mechanism 332.
[0205] In order to obtain the material discharge status in the silo 31 in real time, in some embodiments, the silo cover 33 is provided with a material observation window 314, through which the material discharge status can be observed.
[0206] In some embodiments, a drain port 38 is provided at the bottom of the silo 31 or the bottom of the silo cover 33, and a drain valve 334 is installed at the drain port 38; the drain valve 334 is configured to be openable and closable to drain liquid from the silo 31. The drain valve 334 can be provided on the wall of the silo 31 or on the silo cover 33. The silo cover 33 is a separate component, and providing the drain valve 334 on the silo cover 33 makes the processing of the silo 31 easier.
[0207] When unloading is required, the silo cover locking cylinder retracts, the pull rod assembly 333 is pulled up, and the silo cover clamping mechanism 332 connected to the pull rod assembly 333 is also pulled up. The silo cover clamping mechanism 332 disengages from the discharge port 301 of the silo 31, and the silo cover 33 rotates upward to open the discharge port 301. After unloading is completed, the silo cover locking cylinder extends, the pull rod assembly 333 is lowered, and the silo cover clamping mechanism 332 connected to the pull rod assembly 333 is lowered together. The silo cover clamping mechanism 332 fits against the discharge port 301 of the silo 31, and the silo cover 33 rotates downward to close the discharge port 301.
[0208] To obtain the material level in the hopper 31 in real time, in some embodiments, the storage hopper assembly 3 further includes a material level detection component 51. The material level detection component 51 is installed at the top center of the hopper 31 to detect the material level in the hopper 31. The material level detection component 51 uses a sensor, which is communicatively connected to a controller installed on the power vehicle 100, so that the operator on the power vehicle 100 can obtain the material level information in the hopper 31 of the storage vehicle 200 in a timely manner.
[0209] See Figure 5 and Figure 8 The structure is described below, along with its application in gas dust removal.
[0210] As described above, the silo body 30 is divided into a material silo 31 and two dust collection silos 32 by two partitions 36. To maximize the storage volume of the material silo 31, a flow guiding component 37 can be installed inside the material silo 31 to guide the gas to be filtered to the bottom of the dust collection silo 32. The two dust collection silos 32 are arranged in a one-to-one correspondence with the two flow guiding components 37. In some embodiments, there are two flow guiding components 37, which are arranged with their centers facing each other in the width direction relative to the material silo 31.
[0211] See Figure 8 The flow guide assembly 37 is installed inside the hopper 31; the hopper 31 and the dust removal hopper 32 are connected by the flow guide assembly 37; the connection port 3162 is close to the bottom of the hopper 31; the flow guide assembly 37 is configured to introduce airflow from the top of the hopper 31 to the connection port 3162.
[0212] The flow guiding component 37 adopts a structure that is larger at the top and smaller at the bottom. On the one hand, it minimizes the impact on the storage space at the bottom of the hopper 31, so that the storage volume of the hopper 31 is as large as possible. On the other hand, it also guides the airflow in the hopper 31 to the top of the hopper 31 and enters the interior of the flow guiding component 37 from the air inlet 371 at the top of the hopper 31.
[0213] The dust collection chamber 32 includes a dust collection sealing cover 321. The dust collection sealing cover 321 enables the opening and closing of the dust collection chamber 32 to accommodate the jet cleaning device 322 and the dust filter 323. Each dust collection chamber 32 contains a multi-stage dust filter 323. To ensure maximum filtration of the gas within the silo 31, the air inlet structure 3161 of the first air duct guide device 316 and the air inlet structure 3171 of the second air duct guide device 317 are directed as far as possible to the top of the silo 31. There are three feed inlets 303, labeled feed inlet 311, feed inlet 312, and feed inlet 313. Feed inlets 311, 312, and 313 are positioned as high as possible within the silo 31, but lower than the first air inlet 3161 of the first air duct guide device 316 and the second air inlet 3171 of the second air duct guide device 317. This design maximizes the storage space of the silo 31. The air outlet of the first air duct guide device 316 is the first air outlet 3162, and the air outlet of the second air duct guide device 317 is the second air outlet 3172. Then, through the first air duct guide device 316 and the second air duct guide device 317, the gas is guided to the first air outlet 3162 and the second air outlet 3172, which are located as low as possible in the hopper 31.
[0214] Given that the dust filter 323 is a vertically installed cylindrical shape, the technical solution of this embodiment removes dust from bottom to top, maximizing the utilization of the dust filter 323. The cross-sections of the first air outlet 3162 and the second air outlet 3172 are relatively large rectangles or other shapes, with a large air inlet area, ensuring that the airflow from the hopper 31 contacts all dust filters 323, guaranteeing that all dust filters 323 work simultaneously. Based on the characteristics of gas-solid separation, it ensures that the gas is fully filtered and separated. The filtered gas flows out from the middle of the dust filter 323, and the clean gas from the two dust collection hoppers 32 merges into the confluence duct 318 at the front end of the hopper 31. The downstream of the confluence duct 318 is connected to an outlet bend 315, which is located outside the storage hopper assembly 3 and is fixedly connected to the storage hopper assembly 3. The exhaust bend 315 is sealed and connected to the pipeline (not shown) of the air passage system 10 to deliver the gas in the exhaust bend 315 to the air inlet of the Roots blower in the power vehicle 100. Each Roots blower is connected to the storage bin assembly 3 of the storage vehicle 200 and the pipe-carrying vehicle 300 through a high negative pressure pipeline and the exhaust bend 315 to achieve material suction. Since the exhaust bend 315 is fixedly connected to the storage bin assembly 3, after the storage bin assembly 3 is installed in place, under its own gravity, the exhaust bend 315 and the flexible rubber sealing strip 104 on the pipeline support seat 105 of the air passage system 10 are pressed tightly into contact, ensuring a reliable sealing effect. The gas passes through the pipeline system and finally enters the Roots blower of the power vehicle 100. The airflow undergoes a series of filtration processes again before the clean air is discharged into the atmosphere.
[0215] See also Figure 8 In some embodiments, the flow guiding component 37 includes an air inlet 371 and an air outlet 372. The air inlet 371 of the flow guiding component 37 is located at the top of the silo 31, and the air outlet 372 of the flow guiding component 37 is located at the bottom or lower-middle part of the silo 31. The air outlet 372 of the flow guiding component 37 is connected to the connecting port 3162. The position of the feed inlet 303 is lower than that of the air inlet 371 of the flow guiding component 37. The setting position of the feed inlet 303 of the silo 31 is lower than that of the air inlet 371 of the flow guiding component 37. This allows the buried material to be sucked into the silo 31, with the solid material sinking and the gas overflowing into the dust collection chamber 32. The solid material is less likely to be carried into the dust collection chamber 32, which increases the usable volume of the silo 31. The silo 31 has a high utilization rate and can store more material, thus maximizing the storage space of the silo 31.
[0216] See Figure 7 The storage bin 31 of the storage bin assembly 3 is equipped with an inlet control component 35. Specifically, each inlet 303 is equipped with a valve, and the three valves are labeled as valve 311, valve 312, and valve 313 respectively. In addition, the storage bin 31 includes a material observation window 314 for easy observation of the material level. The first air duct guide device 316, the second air duct guide device 317, and the confluence air duct 318 are all arranged inside the storage bin 31.
[0217] Specifically, the first air duct guiding device 316 includes a first air inlet 3161 and a first air outlet 3162. The second air duct guiding device 317 includes an upper air inlet 3171 and a second air outlet 3172.
[0218] In some embodiments, the storage assembly 3 further includes a dust filter 323, which is installed inside the dust collection chamber 32; the air inlet of the dust filter 323 is located at the bottom of the dust filter 323, and the air outlet of the dust filter 323 is located at the top of the dust filter 323.
[0219] In some embodiments, each dust collection chamber 32 is equipped with a plurality of dust collection filters 323, each dust collection filter 323 being vertically installed inside the dust collection chamber 32; each dust collection filter 323 is configured to start and stop simultaneously.
[0220] In some embodiments, the storage bin assembly 3 further includes a jet cleaning device 322, which is installed inside the dust collection bin 32 and arranged adjacent to the dust collection filter 323 to perform jet cleaning on the dust collection filter 323. During the operation of the storage cart 200, the dust collection filter 323 is periodically backflushed to prevent clogging and ensure dust removal efficiency.
[0221] In some embodiments, the storage chamber assembly 3 further includes a converging air duct 318, which connects to the outlets of the two dust collection chambers 32 to combine the clean fluids removed by the two dust collection chambers 32. The storage chamber assembly 3 integrates functions such as material storage, dust removal, and unloading, exhibiting a high degree of integration. The airflow is divided and merged through the flow guide component 37 and the converging air duct 318, improving the gas filtration effect, effectively achieving gas-solid separation, reducing dust content, and lowering environmental pollution. The airflow path of first dividing and then merging increases the filtration distance of the airflow, ensuring sufficient contact between the airflow and the dust filter 323, achieving the best gas-solid separation effect.
[0222] In some embodiments, the storage vehicle 200 further includes a power generation system 4, which is mounted on the frame assembly 2 and configured to generate electricity to supply power to the storage vehicle 200 and the pipe trailer 300 located upstream of the storage vehicle 200.
[0223] The power generation and supply system 4 includes a control box 41, a generator set 42, and a cable reel 43. The control box 41 is electrically connected to the generator set 42 to control the operating parameters of the generator set 42. The cable reel 43 is used to wind cables, transmitting the electricity generated by the generator set 42 to the pipe-hauling truck 300 through the cables. One storage car 200 can simultaneously supply power to multiple pipe-hauling trucks 300, ensuring that the foremost pipe-hauling truck 300 can operate continuously for extended periods.
[0224] In some embodiments, the storage vehicle 200 also includes lighting equipment mounted on the vehicle's frame assembly. The lighting equipment is powered by a power generation and supply system 4 installed in the storage vehicle 200, enabling rescue operations at night or in poorly lit areas.
[0225] In some embodiments, the storage vehicle 200 further includes multiple cameras, specifically a first camera 52, a second camera 54, a third camera 57, and a fourth camera 58. The first camera 52 and the second camera 54 are located on either side of the storage vehicle 200 in the width direction, the third camera 57 is located at the rear of the storage vehicle 200, and the fourth camera 58 is located at the front of the storage vehicle 200. Each camera is communicatively connected to a controller located on the power vehicle 100, acquiring image information of the storage vehicle 200's surrounding environment within a 360° range, enabling the storage vehicle 200 to operate safely.
[0226] In some embodiments, the storage vehicle 200 also includes a storage vehicle control system 5, which is mounted on the frame assembly 2 and mainly provides control, detection, protection, and remote control functions. The storage vehicle 200 is an unmanned vehicle that moves and controls operating parameters remotely. The storage vehicle control system 5 includes components such as an electrical control box 53 and a negative pressure detection sensor 55 to realize remote control and detection functions.
[0227] In some embodiments, the storage vehicle 200 further includes an engine system 7, which is mounted at the bottom of the frame assembly 2. The engine system 7 provides power for the operation of the entire vehicle. It is longitudinally mounted between the two track assemblies and fixed to the frame, resulting in good symmetry, a low center of gravity, and good vehicle stability.
[0228] In some embodiments, the storage trolley 200 further includes an air circuit system 10, which is installed on the storage bin assembly 3 to achieve dust removal inside the bin 31; the air circuit system 10 is also driven to connect with the feed inlet control component 35 to drive the feed inlet control component 35 to move, thereby realizing the opening and closing of the feed inlet 303.
[0229] The air circuit system 10 includes an air compressor assembly 101, a pipeline assembly 102, an air tank assembly 103, a flexible sealing device 104, and a pipeline connector 105.
[0230] See Figure 6 The air compressor assembly 101 is located outside the storage compartment assembly 3 and is arranged side by side with the storage compartment assembly 3. The air compressor assembly 101 is covered by a surrounding panel assembly 11. The surrounding panel assembly 11 is constructed by welding together multiple plates. The surrounding panel assembly 11 serves to protect the air compressor assembly 101.
[0231] The air compressor assembly 101 is connected to the pulse jet cleaning device 322 via the pipeline assembly 102. The air compressor assembly 101 is used to provide the compressed gas required for the pulse jet cleaning device 322. The air circuit system 10 is responsible for providing the air source for the dust removal system pulse backflushing cleaning, gate valves, lighting equipment and other air-consuming equipment.
[0232] See Figures 11 to 15 The pipe-hauling truck tows the suction pipeline assembly directly to perform suction operations, enabling position control of the suction head. The specific implementation method of the pipe-hauling truck is described below.
[0233] This invention provides a pipe-towing truck 300, including a pipe-towing truck chassis assembly 3001, a slewing boom assembly 3002, and a suction pipe assembly. The pipe-towing truck chassis assembly 3001 includes a chassis component 3011 and a first slewing support 30112, the first slewing support 30112 being mounted on the chassis component 3011. The slewing boom assembly 3002 includes a slewing platform 3021 and a boom assembly 3022; the slewing platform 3021 is mounted on the first slewing support 30112 and configured to slew relative to the first slewing support 30112; the boom assembly 3022 is mounted on the slewing platform 3021. The suction pipe assembly includes a connected suction pipe 30224 and a suction head 30229; the suction pipe 30224 can be a flexible hose, which is lightweight and easy to tow. The suction line 30224 is supported by the slewing platform 3021, and the suction head 30229 is installed on the boom assembly 3022 to adjust the suction position as the boom assembly 3022 changes amplitude.
[0234] The pipe-hauling truck 300 is configured as an unmanned vehicle. The pipe-hauling truck chassis assembly 3001 provides walking support for the equipment. The pipe-hauling truck chassis assembly 3001 is configured to be electrically driven, and the electrical energy comes from the power generation and supply system 4 of the storage truck.
[0235] See Figure 11 and Figure 12 The pipe-hauling truck chassis assembly 3001 includes a chassis component 3011 and a first slewing support 30112. The chassis component 3011 uses tracks as its running gear. The slewing support seat 30111 is mounted between the two tracks and welded to the chassis component 3011. The first slewing support 30112 is specifically connected to the center of the chassis component 3011 via the slewing support seat 30111. The slewing support 30112 is bolted to the slewing support seat 30111 and is used to drive the slewing boom assembly 3002 to rotate, thereby adjusting the circumferential position of the suction head 30229 mounted on the slewing boom assembly 3002, realizing 360° suction operation of the suction head 30229.
[0236] See Figure 13 The rotary platform 3021 is bolted to the rotary support 30112. The rotary platform 3021 includes a mounting base 3020, a suction line support frame, and a first rotary drive component 30212. The boom assembly 3022 is rotatably mounted on the mounting base 3020. At least two suction line support frames are included, each mounted at a different position on the mounting base 3020, thus providing support for different positions of the suction line 30224.
[0237] See also Figure 13In this embodiment of the invention, the suction pipe support frame includes two components: a first suction pipe support frame 30211 and a second suction pipe support frame 30213. The second suction pipe support frame 30213 is fixed to the boom assembly 3022 by bolts, and the first suction pipe support frame 30211 is fixed to the rotary platform 3021 by bolts, serving to assist in fixing the suction pipe 30224.
[0238] See Figure 13 Each suction pipe support bracket includes a support hole b, through which the suction pipe 30224 passes. The first rotary drive component 30212 is mounted on the mounting base 3020 and engages with the first rotary support 30112 of the pipe-hauling vehicle chassis assembly 3001. (See attached image.) Figure 12 The first slewing drive 30212 is configured to drive the mounting base 3020 to rotate relative to the first slewing support 30112. The first slewing drive 30212 is specifically a motor. The first slewing drive 30212 drives the mounting base 3020 to rotate independently and does not provide power for the luffing, second slewing, or travel mechanisms described later; therefore, a smaller model of the first slewing drive 30212 can be selected.
[0239] See also Figure 13 The slewing platform 3021 also includes a pipe trailer enclosure assembly 3003, which is mounted on the mounting base 3020 of the slewing platform 3021. The pipe trailer enclosure assembly 3003 is fixed to the slewing platform 3021 by bolts. The pipe trailer enclosure assembly 3003 is welded from multiple plates and is vertically arranged perpendicular to the top surface of the mounting base 3020. The pipe trailer enclosure assembly 3003 provides safety protection for the equipment.
[0240] See also Figure 13 The boom assembly 3022 is fixedly connected to the slewing platform 3021 by a pin. The first slewing drive component 30212 is fixed to the slewing platform 3021 by bolts and meshes with the slewing support 30112, used to rotate the slewing platform 3021 to realize the change of the suction angle of the boom assembly 3022. The boom assembly 3022 can be a single boom section or multiple boom sections.
[0241] See also Figure 13The boom assembly 3022 includes a first boom section 3022a, a second boom section 3022b, a third boom section 3022c, and a second slewing support 30227. One end of the first boom section 3022a is rotatably mounted to the mounting base 3020, and the first boom section 3022a is configured to be curved. One end of the second boom section 3022b is rotatably connected to the other end of the first boom section 3022a. One end of the third boom section 3022c is rotatably connected to the other end of the second boom section 3022b. The second slewing support 30227 is mounted on the other end of the third boom section 3022c; one end of the suction pipe 30224 is mounted on the second slewing support 30227, and the suction head 30229 is also mounted on the second slewing support 30227. The suction pipe 30224 and the suction head 30229 are rotatably connected and communicate with each other.
[0242] The one-section boom 3022a, two-section boom 3022b, and three-section boom 3022c are all relatively short in length and small in size to meet the requirements of lightweight and easy relocation transportation of the pipe trailer 300.
[0243] See also Figure 13 The boom assembly 3022 also includes a first luffing drive component 30221, a second luffing drive component 30222, and a third luffing drive component 30223, all of which can be hydraulic cylinders. The hydraulic fluid for each cylinder comes from the oil tank carried by the pipe trailer 300 itself, which can greatly shorten the length of the hydraulic pipeline.
[0244] One end of the first luffing drive member 30221 is hinged to the mounting base 3020, and the other end is hinged to the other end of the first arm section 3022a, so as to drive the first arm section 3022a to rotate relative to the mounting base 3020. One end of the second luffing drive member 30222 is hinged to the other end of the first arm section 3022a, and the other end is hinged to one end of the second arm section 3022b, so as to drive the second arm section 3022b to rotate relative to the first arm section 3022a. One end of the third luffing drive member 30223 is hinged to one end of the second arm section 3022b, and the other end is hinged to the second slewing support member 30227, so as to drive the second slewing support member 30227 to rotate relative to the second arm section 3022b.
[0245] The boom sections 3022a, 3022b, and 3022c are all equipped with luffing drive components, making the luffing configuration of the boom assembly 3022 more flexible.
[0246] The first luffing drive component 30221, the second luffing drive component 30222, and the third luffing drive component 30223 are fixedly connected to the boom assembly 3022 by pins. This enables multi-angle suction from the boom, allowing for flexible changes in the suction position. It can suction buried materials from multiple angles and directions, improving adaptability to complex suction rescue environments, reducing the labor intensity of rescue personnel, and increasing suction rescue efficiency. At the same time, it makes the pipe-hauling vehicle 300 small in size and light in weight, with good equipment reliability and rescue timeliness.
[0247] See also Figure 13 The boom assembly 3022 also includes a second slewing drive 30225, which is specifically mounted on the second slewing support 30227 via an end motor mounting base 30226. The second slewing drive 30225 is connected to a hydraulic pump via a hydraulic valve assembly 30422; the second slewing drive 30225 is driven by a suction head 30229 to rotate relative to the suction line 30224. The suction head 30229 is mounted on the second slewing support 30227. The suction head 30229 and the suction line 30224 are connected via a pipe connector 30228.
[0248] The second rotary drive component 30225 can be a motor, which independently drives the suction head 30229 to rotate. Therefore, a smaller motor can be selected, achieving a lightweight design for the pipe-hauling vehicle 300. During suction operations, the second rotary drive component 30225 drives the suction head 30229 to rotate, improving the flexibility of the suction end. The large rotation angle enables multi-angle suction rescue, improving rescue efficiency.
[0249] The second slewing support 30227 is bolted to the boom assembly 3022. The end motor mounting base 30226 is bolted to the boom assembly 3022 and the second slewing support 30227. The second slewing drive 30225 is bolted to the end motor mounting base 30226 and engages with the second slewing support 30227. This drive is used to rotate the suction head 30229 to loosen and break up hardened materials, improving suction efficiency. Specifically, the second slewing drive 30225 can be a motor, which independently drives the suction head 30229. Therefore, a smaller motor can be selected, which is beneficial for achieving a lightweight design of the pipe-hauling truck 300. The second slewing drive 30225 enables the suction head 30229 to rotate. The rotation of the suction head 30229 assists in loosening hardened materials, making suction easier and more adaptable to complex rescue environments and the suction of hardened materials. This results in better suction performance and higher rescue efficiency.
[0250] The multi-degree-of-freedom boom structure and multi-section boom amplitude adjustment enable multi-angle and multi-directional suction and rescue of buried objects. The end-mounted rotation and loosening function improves the adaptability to complex rescue environments and the efficiency of excavation and suction.
[0251] See Figure 13 and Figure 14 The pipe-hauling truck 300 also includes a power system 3004, which provides matching power for all movements of the pipe-hauling truck 300. The power system 3004 includes a drive motor, a hydraulic pump, and a hydraulic valve assembly 30422. The module formed by the drive motor and hydraulic pump drive connection is called the motor-pump assembly 30424. The drive motor is electrically connected to the power supply system of the storage truck 200, and the drive motor is drive-connected to the hydraulic pump. The hydraulic pump is connected to the first luffing drive 30221, the second luffing drive 30222, and the third luffing drive 30223 through the hydraulic valve assembly 30422 to supply oil to these three components. The hydraulic pump is also connected to the first slewing drive 30212 through the hydraulic valve assembly 30422 to provide the first slewing drive 30212 with the power for the vehicle's slewing.
[0252] The hydraulic power of the pipe towing vehicle 300 comes from a hydraulic pump installed on the vehicle. The hydraulic pump is driven by a drive motor, so there is no need to set up a long hydraulic pipeline. Even if the drive motor cannot be powered, power can be supplied through the rechargeable backup battery system described later. The pipe towing vehicle 300 can operate independently, improving the timeliness of rescue.
[0253] See Figure 14 To facilitate the installation of the hydraulic valve assembly 30422, the power system 3004 also includes a hydraulic assembly 3042, which includes a valve assembly mounting bracket 30421 and a radiator 30423. The radiator 30423 is used to cool the hydraulic oil. The valve assembly mounting bracket 30421 is bolted to the slewing platform 3021, the hydraulic valve assembly 30422 is bolted to the valve assembly mounting bracket 30421, and the radiator 30423 and the motor-pump assembly 30424 are bolted to the slewing platform 3021. The drive motor drives the hydraulic pump to provide appropriate flow of hydraulic power for the pipe-hauling truck chassis assembly 3001 to travel, the boom assembly 3022 to luff, and the two slewing movements of the pipe-hauling truck 300.
[0254] The power supply for the pipe trailer 300 comes from the storage car 200. The power generation and supply system 4 of the pipe trailer 300 and the storage car 200 are electrically connected via a cable. The storage car 200 collects the material pumped by the pipe trailer 300 and provides drive power to the pipe trailer 300 through the power generation and supply system 4 and the cable reel, thus further enabling the lightweight design of the pipe trailer 300.
[0255] The power system 3004 uses a drive motor to drive the hydraulic pump. The hydraulic pump then distributes hydraulic oil through the hydraulic valve assembly 30422 to each working link to achieve the following four actions of the pipe-towing truck 300: vehicle travel, boom assembly 3022 luffing, boom assembly 3022 slewing, and suction head 30229 slewing. The pipe-towing truck 300 has its own oil tank, from which all hydraulic components draw oil. This results in very short hydraulic lines, significantly reducing the disadvantages of towing long hydraulic lines and decreasing the load capacity. The motor-driven hydraulic pump assembly eliminates the need for extensive additional hydraulic lines, making the pipe-towing truck 300 smaller and lighter, improving flexibility and efficiency in confined spaces. The motor-driven hydraulic pump assembly provides power for chassis travel and overall machine movement, while the plug-in operation mode ensures the pipe-towing suction rescue equipment's endurance.
[0256] As described above, to achieve lightweight design and enable the pipe-hauling truck 300 to be used in environments with extremely weak load-bearing capacity, such as collapse sites, the pipe-hauling truck 300 itself does not have a generator and cannot generate electricity. However, for emergency response and rescue purposes, the power system 3004 also includes a rechargeable backup battery system. This rechargeable backup battery system is electrically connected to the drive motor to provide emergency rescue power when the drive motor is not electrically connected to the power supply system of the storage truck 200. Equipped with an emergency power module, it can quickly switch to power supply in case of remote power failure, ensuring the timeliness of suction and rescue operations. It also features a built-in emergency power module to quickly switch to power supply in case of remote power failure, ensuring the timeliness of suction and rescue operations.
[0257] See Figure 14 The rechargeable backup battery system includes a lithium battery system 30411, a charging module 30412, a power socket 30413, a rectifier module 30415, and a wireless remote control unit 30416. The rectifier module 30415 is bolted to the rotary platform 3021 and is used to convert the 220V AC power connected to the storage cart 200 into DC power to power the drive motor.
[0258] The lithium battery system 30411 and charging module 30412 are bolted to the rotating platform 3021 and serve as an emergency power source to improve rescue efficiency. The plug-in socket 30413 is bolted to the enclosure assembly 3003 and is used to connect the power source of the storage car 200 to enable plug-in operation, improve the equipment's endurance, and provide power to the pipe-hauling truck 300.
[0259] See also Figure 13 and Figure 14The pipe-laying truck 300 also includes a control unit 30414, an attitude detection component 30417, and a gas concentration detection component 30418. The control unit 30414 is mounted on the slewing platform 3021. The control unit 30414 is bolted to the slewing platform 3021 and executes various actions by controlling the pipe-laying truck's hydraulic system 3042. The attitude detection component 30417 is mounted on the slewing platform 3021 and is configured to detect the attitude of the boom assembly 3022; the control unit 30414 is electrically connected to the attitude detection component 30417. The gas concentration detection component 30418 is mounted on the boom assembly 3022 to detect the gas concentration around the boom assembly 3022.
[0260] Depending on the needs, only one of the attitude detection component 30417 and the gas concentration detection component 30418 may be set, or both may be set.
[0261] See also Figure 13 and Figure 14 The pipe-laying vehicle 300 also includes a video monitoring system 3005, which includes a video processing module 3051, a camera assembly, and a voice communication module 3054. The video processing module 3051 is installed on the slewing platform 3021 and is electrically connected to the camera assembly. The camera assembly is installed at different positions on the slewing boom assembly 3002 to detect images of different areas. The video processing module 3051 is electrically connected to a display located on the power vehicle 100. The voice communication module 3054 is electrically connected to the controller of the power vehicle 100 to enable remote communication between rescue personnel and those being rescued.
[0262] See also Figure 14 The camera assembly includes a gimbal camera 3052 and a dome camera 3053. The gimbal camera 3052 is mounted on the enclosure assembly of the slewing platform 3021. The dome camera 3053 is mounted on the end of the boom assembly 3022 away from the slewing platform 3021.
[0263] The video processing module 3051 is fixed to the rotating platform 3021 with bolts. The pan-tilt camera 3052, the dome camera 3053, and the voice communication module 3054 are fixed to the enclosure assembly 3003 and the boom assembly 3022 with bolts, respectively. The video is decoded and transmitted to the display through the video processing module 3051 to display the rescue scene and the surrounding environment of the equipment in real time. It enables two-way voice communication with the rescued personnel, timely understanding of the physical condition of the rescued personnel, and improves rescue efficiency.
[0264] The pipe-hauling truck 300 is equipped with a wireless remote control unit 30416, a video and voice system, an attitude detection component 30417, and a gas concentration detection element 30418. The video and voice system allows for real-time observation of the on-site rescue situation and voice communication with the rescued personnel. The attitude detection alarm assists in controlling the attitude of the pipe-hauling suction rescue equipment to prevent the entire machine from tipping over.
[0265] The 3005 video surveillance system provides the equipment with on-site visual monitoring and voice intercom functions, enabling long-distance visual voice intercom operation and real-time understanding of the dynamics of the rescue site.
[0266] The attitude detection component 30417 is bolted to the rotating platform 3021 and is used to detect the overall attitude of the machine. When the X-axis tilt angle is greater than S1 or the Y-axis tilt angle is greater than S2, the control unit 30414 receives the signal from the attitude detection component 30417, processes it, and sends it to the buzzer. Upon receiving the signal, the buzzer begins to sound, alerting rescue personnel that the machine may be at risk of tipping over and that the overall attitude needs to be adjusted to protect the equipment. Here, the X-axis is the direction of travel of the pipe-trailer 300. The X-axis tilt angle refers to the angle between the direction of travel of the pipe-trailer 300 and the horizontal plane. The Y-axis is perpendicular to the X-axis in the horizontal plane. The Y-axis included angle refers to the angle between the Y-axis of the pipe-trailer 300 and the horizontal plane.
[0267] The attitude detection component 30417 can monitor the attitude of the pipe towing truck 300, enabling rescue personnel to remotely monitor the dynamics of the rescue site in real time, thus improving the reliability and safety of the rescue operation. Furthermore, when the attitude detected by the attitude detection component 30417 exceeds the limit value, the pipe towing truck 300 will issue an alarm to prevent the risk of overturning, making the suction operation safer and more reliable.
[0268] The gas concentration detection element 30418 is bolted to the boom assembly 3022 and is used to monitor the concentration of hazardous gases at the rescue site in real time, allowing for timely selection of the optimal rescue plan. An alarm will be triggered if the gas concentration exceeds the limit, ensuring the safe and smooth progress of the rescue operation.
[0269] The rescue-end pipe-tow truck 300 is equipped with multi-directional video monitors (not shown in the figure), and the remote control of the pipe-tow truck integrates an independent large-size display screen (not shown in the figure), which can clearly display the audio and video situation at the rescue end in real time.
[0270] The display (not shown in the figure) of the pipe-hauling truck remote control can display the main parameters and alarm information of the power car 100, storage car 200 and pipe-hauling truck 300, allowing the operator to fully understand the key system status of each sub-car in the suction circuit.
[0271] The remote control for the pipe-hauling truck has functions for fan control, unloading control of the storage car 200, self-motion control of the pipe-hauling truck 300, and pipeline switching, which can realize the control of the entire suction circuit and ensure operational safety.
[0272] The following describes practical application scenarios.
[0273] The working process of the rescue suction unit is as follows: The entire unit requires three vehicles to work simultaneously to achieve multi-machine collaborative operation, and the connection method is as follows: Figure 1 As shown. During the burial rescue operation, the layout of the units is determined based on the situation at the rescue site:
[0274] If conditions at the rescue site permit, the storage truck 200 should be placed as close as possible to the pipe-hauling truck 300, and the power vehicle 100 should be parked on the periphery of the rescue site to minimize interference with the rescue operation.
[0275] If the conditions at the rescue site do not allow large, heavy-duty equipment to approach, then only the pipe-hauling truck 300 should be allowed to enter the site, while the power vehicle 100 and the storage truck 200 should be kept away from the rescue site to ensure the safety of the rescue site.
[0276] Therefore, the length of the pipelines between the power vehicle 100, the storage vehicle 200, and the pipe-hauling vehicle 300 is flexible and can be planned according to the site layout. The ultimate goal is to quickly pump out and remove the debris above the buried personnel, avoid injury, and improve the safety and speed of the rescue.
[0277] In the aforementioned technical solution, each of the three sub-vehicles—power vehicle 100, storage vehicle 200, and pipe-hauling vehicle 300—is an independently operating unit. Each vehicle has its own independent power source (engine, battery, or electric motor) to achieve self-propelled movement and provide power for its own working components. The large and noisy power vehicle 100 is positioned on the periphery of the rescue area, while the lightweight and flexible pipe-hauling vehicle 300 replaces rescue personnel to penetrate into the core rescue area. The power vehicle 100, storage vehicle 200, and pipe-hauling vehicle 300 are connected by pipelines. The storage vehicle 200 is flexibly positioned between the power vehicle 100 and the pipe-hauling vehicle 300 to achieve rapid unloading. Even when large equipment cannot enter the rescue area, rescue operations can still be carried out normally, resulting in extremely high rescue efficiency. Each sub-vehicle in the unit has an independent controller for its own action control. The controllers are connected via CAN bus communication technology to achieve data sharing. The communication method can be cable connection or wireless communication. Through bus communication technology, multi-point collaborative operation can be achieved, thereby enabling multi-point synchronous rescue and improving rescue efficiency.
[0278] Each of the power car 100, storage car 200, and pipe-hauling car 300 is equipped with an independent controller to monitor its own status and control its operation. The controllers of each car communicate with each other through CAN bus communication technology to achieve information sharing.
[0279] To enhance the safety of rescue personnel, in addition to the power vehicle 100, the storage vehicle 200 and the pipe-hauling vehicle 300 are all controlled by remote controls, while the power vehicle 100 is controlled by the vehicle's control console. Each of the power vehicle 100, storage vehicle 200, and pipe-hauling vehicle 300 is equipped with a display screen, enabling parameter settings and status display for each vehicle. The remote control for the pipe-hauling vehicle at the rescue end has functions including fan control, material unloading control for the storage vehicle 200, self-motion control for the pipe-hauling vehicle 300, and pipeline switching, enabling control of the entire suction circuit.
[0280] In some embodiments, the power vehicle 100 is also equipped with an oil level sensor (not shown) and temperature sensors (not shown) for detecting the fan inlet temperature and the temperature of critical bearings. The storage vehicle 200 is also equipped with wading level detection, oil level, and oil temperature sensors (not shown). The pipe-hauling vehicle 300 is also equipped with wading level detection and tilt angle detection sensors (not shown). Alarm information from all the above sensors can be displayed on the display of the pipe-hauling vehicle remote control, allowing the operator to fully understand the status of the critical systems of each sub-vehicle in the suction circuit.
[0281] See Figures 16 to 20 The following describes the operation method of the rescue suction unit.
[0282] See Figure 16 and Figure 17 The rescue suction unit provided in this embodiment of the invention is described using the following structure as an example. It should be understood that the following is only an example and does not represent a limitation on the number of each component.
[0283] Taking a rescue suction unit consisting of one power vehicle (100), two storage vehicles (200), and three or six pipe-carrying vehicles (300) as an example, each vehicle has independent power, offering high flexibility and maneuverability to meet the requirements of speed and safety in rescue operations. One power vehicle (100) is equipped with two blowers: a first Roots blower (1033) and a second Roots blower (1042).
[0284] See Figure 16 One power vehicle 100 can connect to a maximum of two storage vehicles 200, and each storage vehicle 200 connects to three pipe-hauling vehicles 300, forming a 1+2+6 arrangement. Here, 1 represents one power vehicle 100, 2 represents two storage vehicles 200, and 6 represents six pipe-hauling vehicles 300. This arrangement maximizes the number of pipe-hauling vehicles 300 connected and is also known as the rescue point maximization working mode. This mode allows up to six pipe-hauling vehicles 300 to operate simultaneously at six different work locations.
[0285] The connected blower is set on the storage car display, and the connected storage car 200 and its corresponding inlet are set on the pipe trailer display. For example, the connection method for a certain pipe trailer 300 is as follows: First Roots blower 1033 + Storage car 200A + Inlet A2 + Pipe trailer 300. After this connection method is selected, the corresponding second solenoid valve 1068 and first solenoid valve 1067 automatically open, the inlet A2 of storage car 200A automatically opens, and the remaining valves remain closed, thus establishing a complete suction circuit. Each pipe trailer 300 selects the corresponding storage car 200 and its inlet on its own display, and selects the corresponding blower and pipeline on the storage car 200 display, thus realizing the suction circuit for each pipe trailer 300.
[0286] During rescue operations, in special circumstances such as excessively viscous suction medium, excessive suction resistance, or the need to increase suction power at a specific rescue point, the first Roots blower 1033 and the second Roots blower 10422 can be combined and used for suction operations via the same pipe-hauling truck 300. At this time, it is necessary to select whether to use the channel where the first Roots blower 1033 or the channel where the second Roots blower 1042 is located to confirm the suction circuit. After the channel selection is completed, the valves of the corresponding merging device will automatically open and close.
[0287] The storage trolley 200 is equipped with a material level sensor (not shown in the figure). When the material level in the trolley is detected to be full, an alarm will be triggered simultaneously on the remote control of the storage trolley and the remote control of the pipe trailer. The operator will then carry out the unloading operation. During the unloading process, the pipe trailer 300 loses its suction power. After the unloading operation is completed, the suction operation will continue.
[0288] See Figure 17 Considering the actual situation, the storage truck 200 needs to unload after being filled with material. During the unloading process, the storage truck 200 cannot continue suction operations. In some cases, extremely high rescue efficiency is required, necessitating uninterrupted rescue operations. A suitable approach can be adopted... Figure 17 The diagram illustrates a continuous operation mode. In this mode, after one storage car 200 is filled with material, the other storage car 200 is switched to suction storage operation, allowing the pipe-hauling truck 300 to continuously perform suction operations without interruption. It should be noted that the switching time between the two storage cars 200 is short and negligible, therefore the pipe-hauling truck 300 is considered to be continuously performing suction operations.
[0289] See also Figure 17There are three pipe-hauling trucks (300 units in total). These three trucks are connected to both the first and second storage trucks (200 units). After the first storage truck (200 unit) is full, the second storage truck (200 unit) is switched to suction mode. After the second storage truck (200 unit) is full, the first storage truck (200 unit) is switched back to suction mode. This switching is achieved by controlling the position of the three-way reversing valve. This arrangement allows the two storage trucks (200 units) to operate alternately, ensuring the continuity of the suction operation of the front-end pipe-hauling trucks (300 units), thereby greatly improving the efficiency of rescue suction and avoiding energy waste from the power vehicle (100 unit).
[0290] See Figure 17 as well as Figure 18 The air inlet of the first Roots blower 1033 of the power vehicle 100 is connected to the exhaust port of the storage vehicle 200A, the second Roots blower 1042 is connected to the exhaust port of the storage vehicle 200B, the pipe trailer 300 is connected to the confluence port of the three-way reversing valve, and the two branch ports of the three-way reversing valve are respectively connected to the feed inlet A1 of the storage vehicle 200A and the feed inlet B1 of the storage vehicle 200B through hoses.
[0291] See Figure 17 A three-way directional valve connects the same pipe-carrying trolley 300 to two storage trolleys 200. The three-way directional valve is pneumatically or electrically controlled. When the three-way directional valve is de-energized, the pipe-carrying trolley 300 is connected to the inlet A1 of storage trolley 200A; when the three-way directional valve is energized, the pipe-carrying trolley 300 is connected to the inlet B1 of storage trolley 200B. The control of the three-way directional valve is performed by the controller of the storage trolley 200. To simplify the selection interface and facilitate operation, the inlets of the storage trolleys 200A connected to each pipe-carrying trolley 300 must be consistent. With this connection method, up to three points of simultaneous suction operation can be achieved.
[0292] The aforementioned three-way reversing valve can be integrated into the pipe trailer 300, the storage car 200, or arranged as an independent unit on the pipeline.
[0293] After the pipeline connection is completed, set the collaborative operation mode via the controller and display as follows:
[0294] See Figure 17The corresponding three-way directional valve, the connected storage cart 200, and the corresponding inlet of the storage cart 200 are set on the display of the pipe-hauling cart. For example, the connection method of a certain pipe-hauling cart 300A is as follows: storage cart 200B + inlet B3 + three-way directional valve A + pipe-hauling cart 300A. After this connection method is selected, the three-way directional valve A is energized, and the pipe-hauling cart 300A is connected to the storage cart 200B. The inlet B3 of the corresponding storage cart 200B automatically opens, and the other valves remain closed, thus disconnecting the circuit. Each pipe-hauling cart 300 selects the corresponding three-way directional valve, storage cart 200, and inlet of the storage cart 200 on its own display, thereby realizing the corresponding suction circuit for each pipe-hauling cart 300.
[0295] In this operating mode, depending on the type of material being pumped and the pumping distance, the first Roots blower 1033 can operate independently, the second Roots blower 1042 can operate independently, or both blowers can operate in a combined manner. The five valves of the blower confluence device are automatically controlled to open and close based on the selected storage cart 200 and the blowers. The specific implementation method is as follows:
[0296] See Figure 17 and Figure 18 When the pipe-carrying trolley 300 selects the storage trolley 200A, the first suction section has the following connection modes: Mode 1: When the first Roots blower 1033 is turned on, the first solenoid valve 1067 and the second solenoid valve 1068 are open and thus connected, while the other solenoid valves are closed and thus disconnected; Mode 2: When the second Roots blower 1042 is turned on, the fourth solenoid valve 10610, the fifth solenoid valve 10611, and the first solenoid valve 1067 are open, while the other solenoid valves are closed; Mode 3: When both the first Roots blower 1033 and the second Roots blower 1042 are turned on, the second solenoid valve 1068, the fourth solenoid valve 10610, the fifth solenoid valve 10611, and the first solenoid valve 1067 are open and thus connected, while the other valves are closed and thus disconnected.
[0297] See Figure 17 and Figure 18 When the pipe-carrying trolley 300 selects the storage trolley 200B, the first suction section has the following connection modes: Mode 1: the first Roots blower 1033 is turned on, the second solenoid valve 1068, the fifth solenoid valve 10611, and the third solenoid valve 1069 are opened, and the other solenoid valves are disconnected; Mode 2: the second Roots blower 1042 is turned on, the fourth solenoid valve 10610 and the third solenoid valve 1069 are opened, and the other solenoid valves are disconnected; Mode 3: both the first Roots blower 1033 and the second Roots blower 1042 are turned on, the second solenoid valve 1068, the fourth solenoid valve 10610, the fifth solenoid valve 10611, and the third solenoid valve 1069 are opened, and the other valves are closed.
[0298] Depending on the specific needs of the site, either the maximum rescue point mode or the continuous operation mode can be selected. In each mode, multiple pipe-hauling trucks can simultaneously carry out rescue operations, enabling multiple machines to conduct simultaneous rescue operations at large-area buried disaster sites, greatly improving rescue efficiency.
[0299] See Figure 19 and Figure 20 This invention provides a method for operating a rescue suction unit, comprising the following steps:
[0300] Step S100: Confirm the working mode of the rescue suction unit.
[0301] The operating modes of the rescue suction unit include: the rescue point maximization mode and the uninterrupted operation mode.
[0302] See Figure 16 and Figure 19 The rescue point maximization working mode means that each power vehicle 100 is connected to two storage vehicles 200, and each storage vehicle 200 is connected to at least three pipe-hauling vehicles 300, so that each of the two storage vehicles 200 can perform suction operations on the three pipe-hauling vehicles 300.
[0303] exist Figure 19 The judgment logic used in the text is as follows: See Figure 19 In the left half, under the maximum rescue point working mode, first determine the working blower. There are three situations: the first Roots blower 1033 works alone, the second Roots blower 1042 works alone, and both the first Roots blower 1033 and the second Roots blower 1042 work.
[0304] The power vehicle 100 includes a first-flow inlet and a second-flow inlet; the storage vehicle 200 includes two units, each with three feed inlets, and more feed inlets can be added as needed. In the maximum rescue point operation mode, there are six pipe-hauling vehicles 300. The first-flow inlet connects to one of the storage vehicles 200, the second-flow inlet connects to the other storage vehicle 200, and each storage vehicle 200 connects to three of the pipe-hauling vehicles 300.
[0305] In the maximum rescue point operation mode, the connection relationship between the storage truck 200 and the pipe-hauling truck 300 is fixed, such as... Figure 18 As shown. When the first Roots blower 1033 operates alone, the first suction section between the storage car 200 and the power car 100 is activated first: the first solenoid valve 1067 opens and the second solenoid valve 1068 opens; then, according to the determined storage car 200, each feed port of the storage car 200 is opened. During the suction process, it is judged in real time whether the hopper of the storage car 200 is full; if it is full, it is unloaded. If the pressure in the hopper of the storage car 200 is too high, the pressure can be reduced by opening the exhaust valve of the corresponding blower.
[0306] See Figure 17 The uninterrupted operation mode refers to the following: each power vehicle 100 is connected to two storage vehicles 200, and the two storage vehicles 200 are connected to three identical pipe-hauling vehicles 300, so that the two storage vehicles 200 alternately perform suction operations on the three pipe-hauling vehicles 300.
[0307] In uninterrupted mode, the rescue logic employed by the rescue unit is as follows: first, select one of the three-way directional valves, i.e., valves A, B, and C. Since each three-way directional valve connects to the inlet of two storage cars, the next step is to select the storage car to be operated. After the storage car is selected, the corresponding pipe-hauling car and storage car can be connected by controlling the energized and de-energized states of the selected three-way directional valve. Each storage car can use three suction power supply methods: the first Roots blower 1033 operates alone, the second Roots blower 1042 operates alone, or both the first Roots blower 1033 and the second Roots blower 1042 operate.
[0308] Regardless of which storage car is operating, the control logic for the suction power is the same: first, determine which fan is working; after identifying the working fan, open the solenoid valve between the fan and the storage car; then, suction operations can begin. During the suction operation, the suction status is monitored in real time. If insufficient suction power or other issues arise, another fan is activated promptly to increase suction power.
[0309] by Figure 19 The leftmost path in the uninterrupted operation mode details the judgment logic.
[0310] First, select the uninterrupted operation mode, then select the three-way directional valve A, and then open the two feed ports connected to the three-way directional valve A: feed ports A1 and B1; select the storage trolley 200A; de-energize the three-way directional valve A, thus completing the connection between the pipe-carrying trolley and the storage trolley. Next, select which of the first Roots blower 1033 and the second Roots blower 1042 will provide the suction power. After selecting the second Roots blower 1042, open the third solenoid valve 1069 and the fourth directional valve 10610 between the second Roots blower 1042 and the corresponding storage trolley 200A to perform the suction operation. During the suction process, monitor the suction status in real time. If it is necessary to open the first Roots blower 1033, open the solenoid valve 1068. During the suction operation, it is also necessary to continuously monitor whether the storage car 200A is full of material and whether the pressure inside the hopper is too high. If it is full, the system switches to another storage car 200B to continue suction while unloading the full storage car 200A. If the pressure is too high, the exhaust valve of the second Roots blower 1042 is opened to reduce the air pressure.
[0311] Step S200: Based on the working mode, determine the storage car 200, the blower, and the pipe-carrying car 300 that need to be used for suction and storage operations.
[0312] The logic for determining the storage car 200, the blower, and the pipe-hauling car 300 differs between the maximized operation mode and the uninterrupted operation mode, as described in detail above. Employing different judgment logic in the two operation modes results in more precise and efficient control.
[0313] Step S300: Connect the suction flow path of the storage car 200; the suction flow path includes a first suction section from the storage car 200 to the power car 100 and a second suction section from the storage car 200 to the pipe trailer 300.
[0314] The air intake of the power vehicle 100 is connected to the exhaust port of the storage vehicle 200 via a suction hose, and the feed inlet of the storage vehicle 200 is connected to the pipe connector of the pipe trailer 300 via a suction hose. In addition, communication lines are established between the power vehicle 100, the storage vehicle 200, and the pipe trailer 300 via wired or wireless means to enable them to establish data connections.
[0315] Step S400: Start the power vehicle 100 located in the first suction section to carry out the suction operation.
[0316] Combination Figure 18 Each of them provides a detailed description of its respective conduction state.
[0317] When the first Roots blower 1033 operates alone and the first storage car 200 stores material, the first solenoid valve 1067 and the second solenoid valve 1068 on the first suction section between the first storage car 200 and the first Roots blower 1033 are activated.
[0318] When the second Roots blower 1042 operates alone and the first storage car 200 stores material, the first solenoid valve 1067, the fourth solenoid valve 10610, and the fifth solenoid valve 10611 on the first suction section between the first storage car 200 and the second Roots blower 1042 are activated.
[0319] When the first Roots blower 1033 operates alone and the second storage car 200 stores material, the third solenoid valve 1069, the second solenoid valve 1068, and the fifth solenoid valve 10611 on the first suction section between the second storage car 200 and the first Roots blower 1033 are activated.
[0320] When the second Roots blower 1042 operates alone and the second storage car 200 stores material, the third solenoid valve 1069 and the fourth solenoid valve 10610 on the first suction section between the second storage car 200 and the second Roots blower 1042 are activated.
[0321] When both the first Roots blower 1033 and the second Roots blower 1042 are working, and the first storage car 200 is storing material, the first solenoid valve 1067, the second solenoid valve 1068, the fourth solenoid valve 10610, and the fifth solenoid valve 10611 on the first suction section between the first storage car 200 and the first Roots blower 1033 and the second Roots blower 1042 are activated.
[0322] When both the first Roots blower 1033 and the second Roots blower 1042 are working, and the second storage car 200 is storing material, the second solenoid valve 1068, the third solenoid valve 1069, the fourth solenoid valve 10610 and the fifth solenoid valve 10611 on the first suction section between the second storage car 200 and the second Roots blower 1042 are activated.
[0323] When controlling the conduction of each solenoid valve, it can be done according to Figure 19 The logic is as follows: First, determine which of the two operating modes to use. After determining the operating mode, identify the operating fan, along with the corresponding storage cart and feed inlet. During the suction process, first determine if the hopper is full, then determine if the negative pressure is too high.
[0324] To activate the second suction section, in the maximum rescue point mode, simply select the storage cart and the feed inlet, and open the corresponding feed inlet. In the continuous operation mode, select the three-way reversing valve, the storage cart, and the feed inlet.
[0325] In some embodiments, the rescue suction unit operation method further includes the following steps:
[0326] Step S500: Determine whether the hopper of the storage car 200 is full.
[0327] Step S600: If the storage hopper of the storage trolley 200 is full, unload the storage trolley 200.
[0328] The storage trolley 200 is equipped with a level sensor. When the sensor detects that the storage trolley 200 is full, it automatically controls the three-way reversing valve to switch to the other storage trolley 200. Simultaneously, both the storage trolley 200 remote control and the pipe-hauling truck remote control trigger a full-level alarm, allowing the operator to unload the full storage trolley 200. This allows storage trolleys 200A and 200B to operate alternately, ensuring the continuity of the pipe-hauling truck 300's suction operation and achieving uninterrupted suction, thus greatly improving rescue suction efficiency and avoiding energy waste from the power vehicle 100. In special circumstances, the two storage trolleys can also be manually switched using the pipe-hauling truck remote control.
[0329] In some embodiments, the rescue suction unit operation method further includes the following steps:
[0330] Step S700: Determine whether the negative pressure in the hopper of the storage car 200 exceeds the set value.
[0331] Step S800: If the negative pressure in the hopper of the storage car 200 exceeds the set value, exhaust the air from the fan located in the same suction flow path as the storage car 200.
[0332] The steps S500 and S700 described above can be performed simultaneously, sequentially, or alternately.
[0333] The storage hopper of the material storage vehicle 200 is equipped with a pressure sensor on its top to monitor the negative pressure value inside the hopper in real time. Each blower inlet pipe of the power vehicle 100 is equipped with an unloading valve, which can be pneumatic or electric. When the pressure inside the working hopper exceeds the set value, the unloading valve at the corresponding blower inlet is opened to prevent excessive pressure in the suction system and excessive negative pressure at the suction end of the pipe-drafting vehicle 300, thus preventing injury to the person being rescued.
