Description

TECHNICAL FIELD

[0002] China is a country with frequent natural disasters and safety accidents. Geological disasters such as earthquakes and mudslides often cause soil burial accidents, which often result in personnel burial. During accident rescue, on the one hand, the rescue area is large, the number of trapped personnel is large, and the burial depth is deep, on the other hand, the rescue window period is short, and the environment is complex, and the 72 hours after the accident is the key period for rescuing lives.

[0003] At present, the efficiency of the fire rescue team in cleaning the buried material above the buried personnel is low, and the buried material above the buried personnel is difficult to quickly remove. When the conventional mechanical equipment (excavators, loaders, bulldozers, etc.) rescue at close range, the contact of large load machinery may cause secondary damage risk (collision, extrusion, etc.) to the buried personnel, so the large load machinery is only suitable for peripheral rescue. The conventional manual tool or manual cleaning method for cleaning the buried material above the buried personnel has high labor intensity and low efficiency. Moreover, at the accident site, secondary collapse is easy to occur, and rescue personnel have a high safety risk.

[0004] The inventor found that at least the following problems exist in the prior art: the existing excavating and suction vehicle for burial rescue is a large vehicle integrated excavating and suction vehicle, which cannot approach the rescue site and is not suitable for large-scale geological disaster rescue.

[0109] For the convenience of description, the length direction L, the width direction W and the height direction H of the storage vehicle 200 are marked in Figure 4 and Figure 5 The length direction of the vehicle frame assembly 2 and the storage bin assembly 3 is the same as the length direction L of the storage vehicle 200; the width direction of the vehicle frame assembly 2 and the storage bin assembly 3 is the same as the width direction W of the storage vehicle 200; and the height direction of the vehicle frame assembly 2 and the storage bin assembly 3 is the same as the height direction H of the storage vehicle 200.

[0110] The inventor has found through long-term research that the area of the buried accident area caused by geological disasters is large, the on-site environment is very complex and harsh, and mechanical equipment is difficult to walk to the area where the trapped personnel are buried. However, the rescue window period is short, and the 72 hours after the accident is the key period for rescuing lives. Simply relying on manual excavation has low efficiency, and the buried material above the buried personnel is difficult to quickly remove. Moreover, the on-site environment of the soil burial accident is extremely complex, and even if small equipment reaches the area where the trapped personnel are located, it is easy to cause secondary harm to the trapped personnel. Therefore, the embodiment of the present application proposes the following technical solutions to provide power for simultaneous rescue at multiple locations, and the rescue efficiency is high, so that it is possible to use equipment to approach the buried personnel at close range to clean the buried material.

[0111] The embodiment of the present application provides a rescue suction unit for soil and other buried material rescue caused by large-area 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 trailer vehicles 300.

[0112] The power vehicle 100 is a high-performance fan mounting platform that provides suction power for the unit operation. The power vehicle 100 adopts a tire chassis, has high mobility, and can quickly move to a designated location. The storage vehicle 200 is an unmanned vehicle.

[0113] Referring to Figures 2 to 4 , some embodiments of the present application provide a power vehicle 100, comprising an off-road chassis 101, a sub-frame 102, a first fan system 103, a second fan system 104, and a fan parallel switching system 106. The off-road chassis 101 comprises a first engine, a chassis 1011 and a power take-off 1012; the first engine and the power take-off 1012 are installed on the chassis 1011; the first engine is drivingly connected with the power take-off 1012. The sub-frame 102 is installed on the chassis 1011; the first fan system 103 comprises a second engine 1031 and a first Roots blower 1033 drivingly connected; the second engine 1031 is installed on the chassis 1011, and the second engine 1031 is drivingly connected with the first Roots blower 1033. The second fan system 104 comprises a second Roots blower 1042; the second Roots blower 1042 is installed on the sub-frame 102 and drivingly connected with the first engine through the power take-off 1012. The fan parallel switching system 106 is installed on the off-road chassis 101; the fan parallel switching system 106 comprises 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 fan 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 flow inlet of the first flow channel 1061 is communicated with the flow outlet of the second flow channel 1062, the second flow channel 1062 is conducted and the flow inlet of the second flow channel 1062 is communicated with the flow outlet of the first flow channel.

[0114] The off-road chassis 101 comprises a chassis 1011, a first engine (not shown in the figure) and a power take-off 1012. The first engine is used to realize the walking of the whole power vehicle 100, and the first engine also provides power for the second Roots blower 1042. The power take-off 1012 of the off-road chassis 101 is installed at the engine flywheel of the chassis 1011, and after power take-off, power output is provided to the second Roots blower 1042 system. The second Roots blower 1042 is directly driven by the engine, and is connected by an automatic clutch. According to the engine speed, the second Roots blower 1042 is disengaged or engaged. The power of the first Roots blower 1033 comes from the separately arranged second engine 1031. The first Roots blower 1033 and the second Roots blower 1042 adopt different power sources. In the case of failure of one power source or insufficient power, the other power source can continue to work, ensuring that the rescue work can be carried out smoothly. This will be described in detail later.

[0115] The mobile modular vacuum suction device is used as the power source of the unit. It has two operation modes, one is independent operation of the fan to realize multi-point material removal, and the other is combined operation of the fan to realize long-distance suction. The fan system is modularly designed, which is more convenient for expanding the capacity of the suction system. The number of fan configurations can be increased to obtain more operation points. The fan system is driven by an automatic clutch, which can automatically engage and disconnect to avoid impact on the engine.

[0116] The power vehicle uses an off-road chassis for transportation, carries multiple fans, has outstanding functions, and is flexible in scene switching. It can also work with multiple material storage vehicles. After a material storage vehicle is full, it switches to another one. The full material storage vehicle drives to the designated location to unload. Compared with the existing integrated excavating and suction vehicle, it realizes continuous and efficient suction operation in heavy suction tasks and improves the efficiency of on-site operation.

[0117] The off-road chassis 101 is a car chassis system for off-road driving. It has a high ground clearance, a powerful suspension system, and a strong chassis structure, making it more suitable for complex terrain and conditions. The off-road chassis 101 is equipped with a four-wheel drive system, which can provide better traction and passability.

[0118] The above advantages make the off-road chassis 101 particularly suitable for occasions with poor road conditions. In areas where geological disasters occur, the off-road chassis 101 can effectively drive the power vehicle 100 to transport, making the power vehicle 100 better able to travel and pass obstacles such as rivers, steep slopes, and rocks on rough terrain. The off-road chassis 101 also has good impact absorption performance to reduce the shock of the vehicle body on uneven roads.

[0119] The sub-frame 102 is bolted to the off-road chassis 101, and the sub-frame 102 adopts a frame structure or a plate structure, so that other components can be more easily installed. In some embodiments, the sub-frame 102 is welded from a plate or a steel pipe, and the sub-frame 102 is installed on the top of the off-road chassis 101, and the sub-frame 102 is used to install and support the first fan system 103, the second fan system 104, and the fan parallel switching system 106. The sub-frame 102 can provide sufficient mounting positions for the first fan system 103, the second fan system 104, and the fan parallel switching system 106, so that they can be more easily installed and positioned. The first fan system 103, the second fan system 104, and the fan parallel switching system 106 are installed together through the sub-frame 102, and the stability and rigidity of the overall vehicle structure are maintained by transferring and dispersing the load. Moreover, the sub-frame 102 has a protective effect, which 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 impact force in the event of a collision.

[0120] The first fan system 103 includes a second engine 1031 and a first Roots blower 1033. The second engine 1031 and the first Roots blower 1033 can be modular, i.e., installed on the same base. The required number and installation position of the first fan system 103 are set as needed. The second engine 1031 is similar to the first engine, which also converts chemical energy into mechanical energy to drive the first Roots blower 1033 to work. However, unlike the first engine, the second engine 1031 is only used to drive the first Roots blower 1033 to work, and does not need to drive the power vehicle 100 to move, so the second engine 1031 can choose a smaller power model. The first Roots blower 1033 inhales the exhaust air from the dust removal bin of the storage vehicle 200, and the first Roots blower 1033 sucks the exhaust air from the dust removal bin of the storage vehicle 200, so that the dust removal bin of the storage vehicle 200, the bin, and the pipeline of the pipe trailer 300 connected with the bin are all in a negative pressure environment.

[0121] The second fan system 104 includes a second Roots blower 1042. The second Roots blower 1042 is also connected with the dust removal bin of the storage vehicle 200 to achieve suction.

[0122] The first Roots blower 1033 and the second Roots blower 1042 are symmetrically distributed at two edges of the width direction of the subframe 102, so that the subframe 102 bears evenly. The first Roots blower 1033 and the second Roots blower 1042 can work independently or cooperatively. Independent work means that the first Roots blower 1033 and the second Roots blower 1042 are respectively connected to a set of storage vehicles 200, the first Roots blower 1033 is used for sucking the storage vehicle 200A, and the second Roots blower 1042 is used for sucking the storage vehicle 200B. Cooperative work means that the first Roots blower 1033 and the second Roots blower 1042 suck the storage vehicle 200A at the same time, or the first Roots blower 1033 and the second Roots blower 1042 suck the storage vehicle 200B at the same time.

[0123] The fan parallel switching system 106 is installed at both sides of the beam at the tail end of the off-road chassis 101 and is fixed by bolts. The fan parallel switching system 106 can effectively realize the switching of the above-mentioned various working states, so that the working mode of the power vehicle 100 is more abundant. 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 a set of storage vehicles 200, and the second flow channel 1062 is connected to another set of storage vehicles 200. Through the switching valve group, the first flow channel 1061 and the second flow channel 1062 are selectively connected, the air inlet of the first flow channel 1061 is shared and the air inlet of the second flow channel 1062 is closed, the air inlet of the second flow channel 1062 is shared and the air inlet of the first flow channel 1061 is closed.

[0124] Referring to Figure 4 , the first flow channel 1061 specifically includes a first flow inlet 1063, a first flow outlet 1064, and a first butt joint 1061a. The second flow channel 1062 includes a second flow inlet 1065, a second flow outlet 1066, and a second butt joint 1062a; the first butt joint 1061a and the second butt joint 1062a are butt-jointed and connected; the switching valve group includes a first electromagnetic valve 1067, a second electromagnetic valve 1068, a third electromagnetic valve 1069, a fourth electromagnetic valve 10610, and a fifth electromagnetic valve 10611; the first electromagnetic valve 1067 is arranged at the first flow inlet 1063, the second electromagnetic valve 1068 is arranged at the first flow outlet 1064, the third electromagnetic valve 1069 is arranged at the second flow inlet 1065, and the fourth electromagnetic valve 10610 is arranged at the second flow outlet 1066; the fifth electromagnetic valve 10611 is arranged at the first butt joint 1061a or the second butt joint 1062a.

[0125] The first flow channel 1061 is a pipe with three openings, one of which is the first flow inlet 1063, the second of which is the first flow outlet 1064, and the third of which is the first interface 1061a. Similarly, the second flow channel 1062 is also a pipe with three openings, one of which is the second flow inlet 1065, the second of which is the second flow outlet 1066, and the third of which is the second interface 1062a. The first interface 1061a and the second interface 1062a are connected together through flanges, so that the first flow channel 1061 and the second flow channel 1062 remain in communication.

[0126] Of course, it is also possible to process by casting or the like, so that the first flow channel 1061 and the second flow channel 1062 are directly integrated.

[0127] The first flow outlet 1064 of the first flow channel 1061 is in communication with the air inlet of the first Roots blower 1033, and the second flow outlet 1066 of the second flow channel 1062 is in communication with the air inlet of the second Roots blower 1042.

[0128] The switching valve group includes a first electromagnetic valve 1067, a second electromagnetic valve 1068, a third electromagnetic valve 1069, a fourth electromagnetic valve 10610, and a fifth electromagnetic valve 10611. Each of the first flow inlet 1063, the first flow outlet 1064, the second flow inlet 1065, the second flow outlet 1066, the first interface 1061a, or the second interface 1062a is provided with an electromagnetic valve, so that each of the five ports can be independently controlled to be on or off. The communication form of the first flow channel 1061 and the second flow channel 1062 has multiple possibilities:

[0129] First, the first flow inlet 1063 and the first flow outlet 1064 are connected, and the second flow inlet 1065 and the second flow outlet 1066 are both connected, and the first interface 1061a or the second interface 1062a is disconnected. This case is suitable for the first Roots blower 1033 to suck the storage vehicle 200A, and the second Roots blower 1042 to suck the storage vehicle 200B. That is, the first Roots blower 1033 and the second Roots blower 1042 work independently.

[0130] Second, the first flow inlet 1063 is connected to the first flow outlet 1064 and the second flow outlet 1066 at the same time, and the first interface 1061a (or the second interface 1062a) is also connected, and the second flow inlet 1065 is disconnected. This case is suitable for the first Roots blower 1033 and the second Roots blower 1042 to suck the storage vehicle 200A at the same time. The first Roots blower 1033 and the second Roots blower 1042 work cooperatively.

[0131] The third mode is different from the second mode in that the first flow inlet 1063 is not in communication with the first flow outlet 1064 and the second flow outlet 1066 at the same time. Initially, the first flow inlet 1063 is directly in communication with the first flow outlet 1064, and the first Roots blower 1033 sucks the storage vehicle 200A. During the sucking operation, the sucking operation is detected in real time. If the power is insufficient, the first flow inlet 1063 is in communication with the second flow outlet 1066, and the second Roots blower 1042 provides additional sucking power, so that the sucking operation of the storage vehicle 200A has more power.

[0132] The fourth mode is that the first flow inlet 1063 is in communication with the first flow outlet 1064 and the second flow outlet 1066 at the same time, and the first interface 1061a or the second interface 1062a is also in communication, and the first flow inlet 1063 is disconnected. This mode is suitable for the first Roots blower 1033 and the second Roots blower 1042 to suck the storage vehicle 200B at the same time. The first Roots blower 1033 and the second Roots blower 1042 work cooperatively.

[0133] The fifth mode is different from the fourth mode in that the first flow inlet 1063 is not in communication with the first flow outlet 1064 and the second flow outlet 1066 at the same time. Initially, the first flow inlet 1063 is directly in communication with the second flow outlet 1066, and the second Roots blower 1042 sucks the storage vehicle 200B. During the sucking operation, the sucking operation is detected in real time. If the power is insufficient, the first flow inlet 1063 is in communication with the first flow outlet 1064, and the first Roots blower 1033 provides additional sucking power, so that the sucking operation of the storage vehicle 200B has more power.

[0134] In some embodiments, at least one of the first electromagnetic valve 1067, the second electromagnetic valve 1068, the third electromagnetic valve 1069, the fourth electromagnetic valve 10610 and the fifth electromagnetic valve 10611 is a butterfly valve, and all of them can be butterfly valves. The butterfly valve has high control accuracy and is easy to install. The opening and closing time of each electromagnetic valve is independently controlled, so that the power vehicle can provide more flexible power mode for the sucking operation of the storage vehicle and the pipe trailer.

[0135] Continuing to refer to Figure 3 and Figure 4 In some embodiments, the power vehicle further comprises a first air supplementing assembly 1034 in communication with the air inlet of the first Roots blower 1033.

[0136] The first air supplement assembly 1034 is used to reduce the operating temperature of the first Roots blower 1033. It includes a first air supplement pipe, an interface, etc. The first air supplement pipe is in communication with the outside atmosphere. When the first Roots blower 1033 sucks the air in the dust collection bin of the storage vehicle, the outside atmosphere also enters the first Roots blower 1033 through the first air supplement pipe of the first air supplement assembly 1034. The first air supplement assembly 1034 provides additional air flow for the first Roots blower 1033 to meet the ventilation requirements under different environmental scenarios and needs. The air supplement amount can be set to be adjustable, and by adjusting the flow area of the first air supplement pipe, the size of the air supplement amount can be adjusted.

[0137] The power vehicle provided by the technical scheme has the advantages that the power vehicle is used for providing suction power, adopts a multi-Roots blower combined control mode, and provides suction power for the operation of the storage vehicle. The first Roots blower and the second Roots blower are switched between independent operation and combined operation modes according to operation needs, can be operated independently or in parallel, provide strong long-distance suction capacity, and maximize the rescue efficiency. In the field rescue, the power vehicle is arranged at the periphery of the rescue area and is used for remotely providing suction power. The storage vehicle and other equipment are connected by a hose.

[0138] In some embodiments, the power vehicle further comprises a first silencer installed upstream of an air inlet of the first Roots blower 1033 to silence the first Roots blower 1033.

[0139] The first silencer is used to reduce the noise of the first Roots blower 1033. The number of the first silencer 105a is two, including a first exhaust silencer 1052 and a first air inlet silencer 1054, which are fixedly connected by bolts and are used to silence the air inlet and air outlet of the first Roots blower 1033, respectively. The first silencer comprises an air inlet section, a sound absorption section and an air outlet section. The air inlet section is used to guide the air flow into the first silencer. The sound absorption section is the main sound absorption area, which absorbs, scatters and reflects noise through internal sound-absorbing materials or other structures, thereby reducing the propagation and influence of noise. The air outlet section is used to release the noise-reduced air flow to the external environment. The structure and material of the first silencer have sound insulation effect, which prevents noise from propagating through walls or other obstacles; the first silencer can also absorb part of the vibration energy, reduce the vibration and noise of the first Roots blower 1033, and reduce the noise to improve the working environment and improve the work efficiency and comfort of the employees.

[0140] Continuing to refer to Figure 3 and Figure 4 In some embodiments, the power vehicle further comprises a second air supplement assembly 1043 in communication with an air inlet of the second Roots blower 1042.

[0141] The second air supplement assembly 1043 supplies additional air to the second Roots blower 1042. It includes a second air supplement pipe, an interface, etc. The second air supplement pipe is in communication with the external atmosphere. When the second Roots blower 1042 sucks air in the dust collection bin of the storage truck, the external atmosphere also enters the second Roots blower 1042 through the second air supplement pipe of the second air supplement assembly 1043. The second air supplement assembly 1043 provides additional air flow to the second Roots blower 1042 to meet the ventilation requirements under different environmental scenarios and needs. The air supplement amount can be set to be adjustable, and the size of the air supplement amount can be adjusted by adjusting the flow area of the second air supplement pipe.

[0142] In some embodiments, the power vehicle further comprises a second muffler mounted upstream of the air inlet of the second Roots blower 1042 to mute the second Roots blower 1042.

[0143] The second muffler 105b is used to reduce the noise of the second Roots blower 1042. The number of the second muffler 105b is two, the second exhaust muffler 1053 and the second air inlet muffler 1054, which are bolted and respectively mute the air inlet and air outlet of the second Roots blower 1042. The second exhaust muffler 1053 and the second air inlet muffler 1054, as well as the first exhaust muffler 1052 and the first air inlet muffler 1054 introduced above, are installed on the bracket 1051 through a clamp, and the bracket 1051 is installed on the subframe 102.

[0144] The second muffler 105b includes an air inlet section, a sound absorption section and an air outlet section. The air inlet section is used to guide the airflow into the second muffler 105b. The sound absorption section is the main sound absorption area, which absorbs, scatters and reflects noise through internal sound-absorbing materials or other structures, thereby reducing the propagation and impact of noise. The air outlet section is used to release the noise-reduced airflow to the external environment. The structure and material of the second muffler have sound insulation effect, which prevents noise from propagating through walls or other obstacles; the second muffler can also absorb part of the vibration energy, reducing the vibration and noise of the second Roots blower 1042. Reducing noise can improve the working environment and improve the work efficiency and comfort of employees.

[0145] In some embodiments, the power vehicle further comprises 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.

[0146] Referring to Figure 5The power vehicle further comprises a power vehicle control system 107, which comprises 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 an air inlet of the first Roots blower 1033 to detect the air inlet pressure of the first Roots blower 1033; and the second pressure detection element 1072 is installed at an air inlet of the second Roots blower 1042 to detect the air inlet pressure of the second Roots blower 1042.

[0147] The power paths and air inlet paths of the first Roots blower 1033 and the second Roots blower 1042 are described below.

[0148] The first blower system 103 mainly comprises a second engine 1031, a clutch assembly 1032, a first Roots blower 1033, a first air supplement 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, as shown in Figure 2 and Figure 3 The first air inlet adapter structure is a bent pipeline.

[0149] The second engine 1031 and the first Roots blower 1033 in the first blower system 103 are connected using the clutch assembly 1032. The first air supplement assembly 1034 is connected to air supplement 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 using the 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 integrally installed on the subframe 102. It can be independently used, or the number of matching units can be increased according to the size of the chassis to increase the suction operation points.

[0150] The second blower system 104 mainly comprises a transmission system 1041, a second Roots blower 1042, a second air supplement 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 blower system 104 mainly comprises a first transmission shaft 10411, a second transmission shaft 10412, a transmission bearing seat 10413, a belt 10414, and a blower pulley 10415.

[0151] The transmission system 1041 of the second fan system 104 is connected to the power take-off 1012 of the off-road chassis 101 at one end and connected to the second Roots fan 1042 at the other end. The second air supplement assembly 1043 is connected to the air supplement openings at both ends of the second Roots fan 1042. The air outlet of the second safety filter cartridge 1045 and the air inlet of the second Roots fan 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.

[0152] During the suction operation, when the first pressure detection element 1071 detects that the pipeline negative pressure is too high and exceeds the set value, in order to prevent damage to the system structure caused by long-time high pressure, the controller sends a control signal to open the first unloading valve 1038 for a duration of, for example, 3s, so that external air is sucked into the fan inlet pipeline, and the system working pressure is limited within a certain range.

[0153] 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 for a duration of, for example, 3s, so that external air is sucked into the fan inlet pipeline, and the system working pressure is limited within a certain range. The highest working negative pressure can be set on the display and can be set to different values according to different situations.

[0154] The storage vehicle 200 is self-powered and uses a tracked chassis to walk, with strong obstacle crossing ability and remote control operation to walk to the designated rescue site.

[0155] The towed pipe vehicle 300 is also an unmanned vehicle, and the towed pipe vehicle 300 is self-powered and uses a tracked chassis to walk, and is the "hand" and "eye" of the rescue personnel, which can observe the rescue site in real time through the camera.

[0156] The power vehicle 100 is used to provide suction power, which can be provided by one or two Roots fans, so that the buried material is sucked into the towed pipe vehicle 300 and then into the storage vehicle 200. The suction power required by the towed pipe vehicle 300 comes from the power vehicle 100. The towed pipe vehicle 300 does not need to be provided with a storage cavity, and the buried material sucked into the towed pipe vehicle 300 is directly sucked into the storage vehicle 200 through the towed pipe vehicle 300 and stored. Therefore, the size of the towed pipe vehicle 300 can be set to be light and small, so that the towed pipe vehicle 300 can be easily moved to the vicinity of the buried person to quickly perform the operation of sucking and removing the buried material.

[0157] Each power vehicle 100 is connected to at least two storage vehicles 200, that is, one power vehicle 100 can provide suction power for two or more storage vehicles 200 at the same time. The operation of each storage vehicle 200 is independently controlled, and each storage vehicle 200 can work independently or multiple storage vehicles 200 can work at the same time. The working mode is various, which can better meet the use requirements of different scenes.

[0158] Specifically, the power vehicle 100 is connected to the warehouse body 30 of the storage vehicle 200 to provide suction power to the warehouse body 30. The warehouse body 30 of the storage vehicle 200 is connected to the suction pipeline 30224 of the trailer vehicle 300, and under the action of the negative pressure power provided by the power vehicle 100, the suction pipeline 30224 of the trailer vehicle 300 is also under negative pressure. The buried material at the accident scene can be quickly sucked into the suction pipeline 30224, and then stored in the warehouse body 30 of the storage vehicle 200 under the action of the gravity of the buried material itself. It should be noted that when the buried material is sucked, liquid may also be sucked. The liquid can be stored in the storage vehicle 200 or not. If it is not necessary to store in the storage vehicle 200, the liquid can be discharged by opening the pollution discharge port 38 of the storage vehicle 200. If it is necessary to store in the storage vehicle 200, the storage vehicle 200 can be moved to the pollution discharge area, and then the pollution discharge port 38 is opened to discharge the liquid.

[0159] Each storage vehicle 200 is connected to at least two trailer vehicles 300. The storage vehicle 200 and the trailer vehicle 300 are connected through a pipeline, and each trailer vehicle 300 is connected to the feed port 303 of the storage warehouse assembly 3 of the storage vehicle 200 introduced below. The length of the pipeline corresponding to each trailer vehicle 300 can be flexibly set according to the needs to realize rescue work at different locations. Each pipeline is designed with a quick connector for flexible replacement of pipelines of different lengths. Each trailer vehicle 300 can work at the same time to transmit the sucked buried material to the same storage vehicle 200, which realizes multi-pipeline and multi-point cooperative long-distance suction operation, greatly improving the rescue efficiency.

[0160] The second connecting pipeline 500 is used to connect the storage vehicle 200 and each pipe trailer 300, instead of using the mode of screw conveying or conveying belt conveying. On the one hand, the requirement for the shape of the buried material is reduced, and as long as the buried material can be sucked into the pipeline, the buried material can be conveyed into the storage vehicle 200 for storage. Moreover, the buried material entering the storage vehicle 200 directly falls and deposits under the action of its own gravity, so it is not easy to accumulate in the same place, but can spread in each area of the storage bin 31 of the storage vehicle 200, which improves the storage efficiency of the storage vehicle 200. The material can be deposited without human intervention, which reduces the step of manual handling, and the operation is more automated and efficient, and is more suitable for application in a geological disaster rescue area with a very short rescue window. On the other hand, the pipeline is light in quality, and it is easier for the pipe trailer 300 to walk with the pipeline. Under the same carrying capacity of the pipe trailer 300, compared with other conveying modes, the size of the pipeline can be set longer, and the pipe trailer 300 is more suitable for entering the dangerous area far away from the personnel.

[0161] The power vehicle 100 is provided with at least one Roots blower. When a single Roots blower works, the air inlet port of the power vehicle 100 is connected to the rotating flange pipeline interface of the pipeline assembly 102' of the storage vehicle 200 through the first connecting pipeline 400 to complete the connection between the power vehicle 100 and the storage vehicle 200. By opening the inlet plug valve of a storage vehicle 200 and connecting the plug valve and the pipeline interface of a pipe trailer 300 through the pipeline, 1+1+1 operation can be performed. By opening two inlet plug valves and connecting two pipe trailers 300, a 1+1+2 operation mode can be realized. By opening three inlet plug valves and connecting three pipe trailers 300, a 1+1+3 operation mode can be realized. If two blowers on the power vehicle 100 work simultaneously, the two blowers can provide power for two storage vehicles 200, and similarly, a 1+2+6 operation mode can be realized at most.

[0162] The rescue suction unit provided by the above technical solution is designed in a 1+2+N split combination, wherein 1 represents a power vehicle 100, 2 represents two storage vehicles 200, and N represents N pipe trailers 300. The number N is greater than or equal to 4. The storage vehicle 200 is used to connect the power vehicle 100 and the pipe trailer 300 in the whole unit. After the power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are positioned, the high-negative-pressure hose is used to connect the power vehicle 100 and the storage vehicle 200, and the storage vehicle 200 and the pipe trailer 300 through quick-change joints, so as to save the preparation time of rescue, strive to complete the preparation work before rescue at the fastest speed, and ensure that the unit is put into rescue work. Here, all the positioning means that the power vehicle 100, at least one storage vehicle 200 and at least one pipe trailer 300 are positioned to carry out rescue. For the area where personnel cannot reach, the pipelines between the vehicles can be connected first, and then the vehicles can be moved to the designated rescue site.

[0163] The rescue suction unit provided by the technical scheme has high modularization, and the main functions of each sub-car are prominent.

[0164] Referring to Figure 5 and Figure 6 , the material sucked at the suction end is stored in the storage car 200, and the material is settled in the storage bin by using the principle of inertial settlement, and the airflow is filtered by the dust removal device and enters the fan of the power car 100. The specific implementation mode of the storage car 200 will be described below.

[0165] The embodiment of the application provides a storage car 200, which comprises a walking mechanism 1, a car frame assembly 2 and a storage bin assembly 3. The car frame assembly 2 is installed on the walking mechanism 1. The storage bin assembly 3 is installed on the car frame assembly 2; the storage bin assembly 3 comprises a bin body 30, a bin cover 33 and at least two feed port control components 35; the bin body 30 is provided with a discharge port 301, an air outlet 304 and at least two feed ports 303, and the bin cover 33 is installed at the discharge port 301 in an openable and closable manner. In the following, three feed ports 303 are taken as an example, and more feed ports 303 can also be provided if necessary. Each feed port 303 is provided with a feed port control component 35 for controlling the opening and closing of the feed port 303. The feed port control component 35 can be a pneumatic or electric control valve.

[0166] The storage car 200 provided by the technical scheme is used for collecting and transporting buried materials, and comprises a walking mechanism, a car frame assembly and a storage bin assembly. The storage bin assembly is used for receiving the buried materials delivered by the upstream pipe trailer 300, and has at least two feed ports, each of which is connected to one pipe trailer 300. The pipe trailers 300 connected to the storage bin assembly of the same storage car 200 can be located at different working positions, so that multi-point simultaneous rescue is realized, and the rescue efficiency is greatly improved. Since the pipe trailer 300 directly delivers the buried materials to the storage car 200, the pipe trailer 300 does not need to be provided with a storage cavity, so the structure of the pipe trailer 300 can be very small and light, and the operation is more flexible. The pipe trailer 300 can also be set as an unmanned vehicle to protect the rescue personnel. The small, light and flexible pipe trailer 300 is more easily close to the collapsed area, the dangerous area where personnel cannot enter, and the soil buried area of geological disasters, which makes mechanical rescue possible and greatly improves the possibility of rescue, so that more rescue operations can be completed within the rescue window period.

[0167] The walking mechanism 1 is used to realize the movement and transfer of the storage vehicle 200. The environment of the buried accident area is extremely complex, and the walking is difficult. The walking mechanism 1 can adopt a caterpillar walking mechanism 1 to increase the contact area between the walking mechanism 1 and the ground, so that the storage vehicle 200 can travel on various uneven and muddy roads.

[0168] The walking mechanism 1 includes two caterpillars arranged at the two edges of the width direction of the bottom of the frame assembly 2. The two caterpillars have strong carrying capacity, strong structural stability, flexible operation, and strong maneuverability, can effectively support the frame assembly 2, so that the volume of the bin body 30 of the storage vehicle 200 can be set to be relatively large, and more buried materials can be carried at one time, so that the volume of the bin can be set to be larger, the storage and transfer of the buried materials are realized, and the rescue efficiency of the unit is effectively improved.

[0169] The frame assembly 2 is used to support the storage bin assembly 3. The structure of the frame assembly 2 can be set to be as light as possible to realize the lightweight of the product, so that the storage bin assembly 3 can carry more buried materials under the premise that the carrying capacity of the caterpillar is unchanged.

[0170] Referring to Figures 5 to 8 , the storage bin assembly 3 includes a bin body 30, a bin cover 33, and at least two inlet control assemblies 35. The bin body 30 is used for storage, and the bin cover 33 is used for opening and closing the bin body 30. When the bin cover 33 is in the closed state, the buried materials can enter the bin body 30 through the pipe car 300 and the inlet control assembly 35. When the bin cover 33 is in the open state, the buried materials stored in the bin body 30 are discharged to the outside or other garbage transfer vehicles.

[0171] The storage bin assembly 3 and the rear rotating hinge point of the frame assembly 2 are connected by a pin shaft, one end of the amplitude cylinder (not shown in the figure) is connected to the middle cross beam of the frame assembly 2 through the pin shaft, 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 amplitude 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, the front end of the storage bin assembly 3 is high, the rear end is low, the discharge port 301 of the storage bin assembly 3 is arranged at the rear end, and under the action of its own gravity, the materials in the storage bin assembly 3 can be discharged.

[0172] The bin body 30 comprises a discharge port 301, an air outlet 304 and at least two feeding ports 303. The feeding ports 303 are used to convey the buried material from the upstream pipeline to the inside of the bin body 30. The opening and closing operations of each feeding port 303 are independent and have no influence on each other, and each feeding port 303 can be opened simultaneously or at intervals. In the case that each feeding pipe is connected to a trailer 300 respectively, the feeding port 303 corresponding to the trailer 300 which reaches the destination first can be opened first, and the trailer 300 can also be started first. The feeding port 303 corresponding to the trailer 300 which reaches the destination later can be opened later, so that automatic control of each feeding port 303 can be realized, multi-point suction rescue and non-stop operation can be realized, and the rescue efficiency is high.

[0173] The buried material is generally solid, but in the case of water disasters and the like, the buried material can also contain a large amount of liquid. In the case of the trailer 300, both liquid and solid can be sucked into the pipeline of the trailer 300 and then conveyed into the bin body 30 of the storage car 200. And a large amount of dirty air can also be generated in the suction process.

[0174] The bin body 30 can be processed according to the different forms of solid, liquid and gas. When working, the buried material as a whole enters the bin body 30 through the feeding port 303 of the bin body 30 in the flow direction of the buried material. Then, according to the different properties of the buried material, three processing methods are adopted:

[0175] Firstly, the solid will automatically settle at the bottom of the bin body 30 under its own gravity. After the bin body 30 is filled with solid, the discharge port 301 is opened to discharge the solid in the bin body 30.

[0176] Secondly, after the liquid is sucked into the storage car 200 from the trailer 300, the liquid can be discharged at the location of the storage car 200 since the storage car 200 is a certain distance away from the trailer 300, such as 140-160 meters. That is, the exhaust valve 334 of the bin body 30 is opened to discharge the liquid.

[0177] Thirdly, the gas can be discharged into the atmosphere after purification or conveyed to other components using gas power.

[0178] In order to realize the processing of various different substances, in some embodiments, the bin body 30 comprises a partition 36 arranged inside the bin body 30, which is for example a plate, and the partition 36 is formed by one or more plates. The partition 36 divides the bin body 30 into a material bin 31 and a dust removal bin 32; the partition 36 is provided with a communication port 3162; each feeding port 303 is arranged on the material bin 31, and each feeding port 303 is specifically arranged on the tail wall of the material bin 31. The gas outlet 304 is arranged on the dust removal bin 32. The material bin 31 and the dust removal bin 32 are jointly provided with a discharge port 301. The material bin 31 is used for storing solids, and the dust removal bin 32 is used for dust removal of the gas sucked into the material bin 31. When the bin cover 33 is opened, the solid material in the material bin 31 and the dust filtered out of the dust removal bin 32 can be discharged at the same time.

[0179] Referring to Figure 5 In some embodiments, the number of partitions 36 is two, and the partitions 36 are parallel to the length direction of the storage car 200, and along the width direction W of the storage car 200, the bin body 30 is divided into three parts: two dust removal bins 32 on both sides of the width direction, and a material bin 31 between the two dust removal bins 32. The bin body 30 is designed by zones, and the dust removal and storage functions are reasonably arranged. The material bin 31 and the dust removal bin 32 are arranged along the width direction of the storage car 200 instead of along the length direction of the storage car 200, so that the gas can enter the various areas of the dust removal bin 32 more evenly, so that each dust removal filter 323 in the dust removal bin 32 can be more evenly supplied with air, and each dust removal filter 323 can be fully utilized, greatly improving the dust removal efficiency. If the material bin 31 and the dust removal bin 32 are arranged along the length direction of the storage car 200, after the gas flow enters the material bin 31 from the tail of the material bin 31, it needs to flow through the entire material bin 31 to reach the dust removal bin 32 at the front end. After entering the dust removal bin 32, the gas flow first contacts the dust removal filter 323 closest to the material bin 31 in the dust removal bin 32, which causes the dust removal filter 323 to be easily blocked, but the utilization rate of the dust removal filters 323 far away from the material bin 31 is poor.

[0180] As introduced above, the storage bin assembly 3 is divided into left, middle and right parts, and the middle part is the material bin 31, and the two sides are the dust removal bins 32. The two dust removal bins 32 are arranged on both sides of the material bin 31, and the material bin 31 and the dust removal bin 32 are communicated through a flow guide assembly 37. The flow guide assembly 37 comprises a first air duct flow guide device 316 and a second air duct flow guide device 317. One of the dust removal bins 32 is communicated with the material bin 31 through the first air duct flow guide device 316, and the other dust removal bin 32 is communicated with the material bin 31 through the second air duct flow guide device 317.

[0181] The specific implementation of the material bin 31 is introduced below.

[0182] Referring toFigure 6 The bin 31 is provided with respective feed ports 303. The dust removal bin 32 and the bin 31 are jointly provided with a discharge port 301. The discharge port 301 simultaneously discharges the solids in the bin 31 and the dust filtered out by the dust removal bin 32. The width of the discharge port 301 is substantially the same as the total width of the dust removal bin 32 and the bin 31. The discharge port 301 can be arranged at the lower half of the tail of the bin 31. The height of the discharge port 301 is about half the height of the bin 31, and the bottom of the discharge port 301 is flush with the bottom edge of the bin 31. The bin cover 33 for closing the discharge port 301 is opened in a pivoting manner. The pivoting angle is, for example, 85°-95°. Specifically, the top of the bin cover 33 is pivotally connected to the bin 31. This manner can maximize the bin cover 33, so that the solids and liquids in the bin 31 can be quickly discharged to meet the requirement of extremely short rescue window period.

[0183] According to the negative pressure suction principle, as long as the feed port 303 is opened, the material will continuously enter the bin 31 through the suction pipeline 30224 connected at the plug valve at the rear of the bin 31. The blowdown valve 334 can discharge the suctioned liquid material to ensure that as much solid material as possible is stored in the bin 31, and the space of the bin 31 is maximized.

[0184] Referring to Figure 6 The bin 31 is provided with respective feed ports 303. The dust removal bin 32 and the bin 31 are jointly provided with a discharge port 301. The discharge port 301 simultaneously discharges the solids in the bin 31 and the dust filtered out by the dust removal bin 32. The width of the discharge port 301 is substantially the same as the total width of the dust removal bin 32 and the bin 31. The discharge port 301 can be arranged at the lower half of the tail of the bin 31. The height of the discharge port 301 is about half the height of the bin 31, and the bottom of the discharge port 301 is flush with the bottom edge of the bin 31. The bin cover 33 for closing the discharge port 301 is opened in a pivoting manner. The pivoting angle is, for example, 85°-95°. Specifically, the top of the bin cover 33 is pivotally connected to the bin 31. This manner can maximize the bin cover 33, so that the solids and liquids in the bin 31 can be quickly discharged to meet the requirement of extremely short rescue window period.

[0185] During discharge, the bin cover locking oil cylinder is connected to the pull rod assembly 333 and the bin cover pressing mechanism 332. The bin cover locking oil cylinder is retracted. The pull rod assembly 333 first drives the locking device to be disconnected from the locking ring (not shown in the figure). When the locking device is rotated to a maximum of 30°, the bin cover locking oil cylinder is further retracted. The bin cover 33 is rotated to be opened by 90° under the action of the bin cover locking oil cylinder. The entire bin cover 33 is opened, and the discharge operation starts. The pull rod assembly 333 can realize rotational adjustment of the length. The threads on the pull rod are opposite. Rotating the pull rod can realize elongation or shortening, so as to ensure that the bin cover 33 is always in a pressed state.

[0186] The above-mentioned bin cover driving mechanism 34 realizes the interlocking action of opening / closing the bin cover 33 and locking and sealing the bin cover 33 by using one bin cover locking oil cylinder, has an error prevention function, and must first loosen the locking device before opening the bin cover 33 during the action of the bin cover locking oil cylinder. The action of opening the bin cover 33 without loosening the bin cover 33 does not occur, and misoperation is avoided.

[0187] After the unloading is completed, the bin cover locking oil cylinder is extended, and first, the bin cover 33 is closed, and the oil cylinder is continuously extended to push the locking device connected with the pull rod assembly 333 to further press the bin cover 33, so as to ensure the sealing effect of the bin cover 33.

[0188] Continuing to refer to Figure 6 In order to facilitate the opening and closing of the bin cover 33, in some embodiments, the storage bin assembly 3 further comprises a bin cover driving mechanism 34 which is installed on the storage bin assembly 3 and is drivingly connected with the bin cover 33 to drive the bin cover 33 to open and close. The bin cover driving mechanism 34 can be driven in a pneumatic or hydraulic manner. The bin cover driving mechanism 34 is configured to rotate the bin cover 33 by 85° to 95°

[0189] Continuing to refer to Figure 6 In some embodiments, the bin cover driving mechanism 34 comprises a bin cover locking oil cylinder, a pull rod assembly 333 and a bin cover pressing mechanism 332. The bin cover locking oil cylinder comprises a cylinder barrel and a piston, and one of the cylinder barrel and the piston is rotatably connected with the bin body 30. One end of the pull rod assembly 333 is rotatably connected with the other one of the cylinder barrel and the piston. The bin cover pressing mechanism 332 is connected with the other end of the pull rod assembly 333 to drive the bin cover 33 to open and close with the extension and retraction of the bin cover locking oil cylinder; and the bin cover pressing mechanism 332 is sealingly matched with the unloading port 301 of the bin 31.

[0190] In some embodiments, the storage vehicle 200 further comprises a storage vehicle hydraulic system 9 and an oil tank assembly 8. The storage vehicle hydraulic system 9 is in fluid communication with the bin cover locking oil cylinder to realize the extension and retraction control of the bin cover locking oil cylinder. The oil tank assembly 8 provides hydraulic oil for the entire storage vehicle hydraulic system 9. The storage vehicle hydraulic system 9 provides hydraulic power for each functional component to realize the chassis travel, unloading control, air compressor and generator functions of the storage vehicle.

[0191] The bin cover pressing mechanism 332 and the unloading port 301 of the bin 31 are sealingly matched by the following structure: in some embodiments, the bin cover pressing mechanism 332 comprises a mounting member and a locking hook. The mounting member is connected with the other end of the second pull rod; the locking hook is installed on the mounting member; and the mounting member can adopt a plate member or a rod member. The bin body 30 is correspondingly provided with a locking ring which can be hooked and unhooked with the locking hook. The number of the locking ring and the locking hook is both multiple, and the locking ring and the locking hook are arranged in one-to-one correspondence. The locking ring can be provided with multiple hooking positions, and the locking hook can be hooked at different positions as needed to meet different sealing requirements.

[0192] The bin cover pressing mechanism 332 further comprises a sealing member which is installed on the mounting member or directly installed on the edge of the bin cover 33. The sealing member is provided in the area where the bin cover 33 can contact the unloading port 301. The sealing member can adopt a sealing strip which is sealingly matched with the unloading port 301.

[0193] After being used for a period of time, the sealing strip may be deformed and fail, and the sealing effect of the sealing strip on the discharge opening 301 is poor. In order to adjust the sealing effect of the sealing strip, in some embodiments, the pull rod assembly 333 is configured to be telescopic to adjust the pressing force between the pressing cover 33 and the bin 31. When the sealing strip is deformed and fails, the length of the pull rod assembly 333 is increased, so that the sealing between the bin 31 and the pressing cover 33 is reliable, the problem that the pressing cover 33 cannot be pressed due to the change in the rebound amount of the sealing member is compensated, the pressing cover 33 is always in a pressed and sealed state, and the safety and practicability of operation are improved.

[0194] In some embodiments, the pull rod assembly 333 includes a sleeve, a first pull rod, and a second pull rod. The sleeve includes a first threaded hole and a second threaded hole in communication. One end of the first pull rod is provided with a first thread, which is threadedly connected with the first threaded hole. The other end of the first pull rod is rotatably connected with one of the cylinder and the piston. One end of the second pull rod is provided with a second thread, which is threadedly connected with the second threaded hole. The other end of the second pull rod is connected with the cover pressing mechanism 332.

[0195] In order to obtain the discharging condition of the material in the bin 31 in real time, in some embodiments, the cover 33 is provided with a material observation window 314, through which it can be observed whether the discharging of the material is completed.

[0196] In some embodiments, the bottom of the bin 31 or the bottom of the cover 33 is provided with a blowdown opening 38, and a blowdown valve 334 is installed at the blowdown opening 38. The blowdown valve 334 is configured to be openable and closable to discharge the liquid in the bin 31. The blowdown valve 334 can be arranged on the wall of the bin 31 or on the cover 33. The cover 33 is a separate component, and arranging the blowdown valve 334 on the cover 33 can make the bin 31 easier to process.

[0197] When discharging is needed, the cover locking oil cylinder is retracted, the pull rod assembly 333 is pulled up, the cover pressing mechanism 332 connected with the pull rod assembly 333 is also pulled up, the cover pressing mechanism 332 is separated from the discharge opening 301 of the bin 31, and the cover 33 is rotated upward to open the discharge opening 301. After the discharging is completed, the cover locking oil cylinder is extended, the pull rod assembly 333 is lowered, the cover pressing mechanism 332 connected with the pull rod assembly 333 is also lowered, the cover pressing mechanism 332 is attached to the discharge opening 301 of the bin 31, and the cover 33 is rotated downward to close the discharge opening 301.

[0198] In order to obtain the material level in the material bin 31 in real time, in some embodiments, the storage bin assembly 3 further comprises a material level detection assembly 51 installed in the middle of the top of the material bin 31 to detect the material level in the material bin 31. The material level detection assembly 51 adopts a sensor which is in communication connection with a controller arranged on the power vehicle 100, so that the operator on the power vehicle 100 can obtain the material level information in the material bin 31 of the storage vehicle 200 in time.

[0199] Referring to the structure of Figure 5 and Figure 8 , the gas dust removal will be introduced below.

[0200] As introduced above, the bin body 30 is divided into a material bin 31 and two dust removal bins 32 by two partitions 36; in order to make the storage volume of the material bin 31 as large as possible, a flow guide assembly 37 can be arranged in the material bin 31 to introduce the gas to be filtered into the bottom of the dust removal bin 32 through the flow guide assembly 37. The two dust removal bins 32 are arranged in one-to-one correspondence with the two flow guide assemblies 37. In some embodiments, the number of flow guide assemblies 37 is two, and the two flow guide assemblies 37 are arranged opposite to the center plane of the material bin 31 in the width direction.

[0201] Referring to Figure 8 , the flow guide assembly 37 is installed inside the material bin 31; the material bin 31 and the dust removal bin 32 are communicated through the flow guide assembly 37; the communication port 3162 is close to the bottom of the material bin 31; the flow guide assembly 37 is configured to introduce the gas flow from the top of the material bin 31 to the communication port 3162.

[0202] The flow guide assembly 37 adopts a structure of large at the top and small at the bottom, which on the one hand reduces the influence on the storage space at the bottom of the material bin 31 as much as possible, so that the storage volume of the material bin 31 is as large as possible; on the other hand, it also makes the gas flow in the material bin 31 be guided to the top of the material bin 31, and enters the inside of the flow guide assembly 37 from the air inlet 371 of the flow guide assembly 37 at the top of the material bin 31.

[0203] The dust removal bin 32 comprises a dust removal sealing cover 321. The dust removal sealing cover 321 realizes the opening and closing of the dust removal bin 32, so as to install the blowing device 322 and the dust removal filter 323. A plurality of levels of dust removal filters 323 are installed in each dust removal bin 32. In order to ensure that the gas in the storage bin 31 can be filtered to the maximum extent, 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 are introduced to the top of the storage bin 31 as much as possible. The feeding port 303 has three, which are marked as feeding port 303a, feeding port 303b and feeding port 303c. The feeding ports 303a, 303b and 303c are arranged as high as possible in the storage bin 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 form can ensure that the storage space of the storage bin 31 is maximized. The air outlet of the first air duct guide device 316 is the first air outlet, and the air outlet of the second air duct guide device 317 is the second air outlet 3172. Then the gas is introduced to the first air outlet and the second air outlet 3172 at the lowermost position of the storage bin 31 through the first air duct guide device 316 and the second air duct guide device 317.

[0204] In view of the fact that the dust removal filter 323 is a vertically installed cylindrical body, the technical scheme of the embodiment of the present application removes dust from bottom to top, so that the dust removal filter 323 is utilized to the maximum extent. The cross section of the first air outlet and the second air outlet 3172 is a large-size rectangle or other shape, the air inlet area is large, which ensures that the airflow coming from the storage bin 31 contacts all the dust removal filters 323, and ensures that all the dust removal filters 323 work simultaneously. According to the characteristics of gas-solid separation, the gas is fully filtered and separated, and the filtered gas flows out from the middle of the dust removal filter 323, and the clean gas from the two dust removal bins 32 converges into the converging air duct 318 at the front end of the storage bin assembly 3. The downstream of the converging air duct 318 is communicated with the air outlet elbow 315, which is located outside the storage bin assembly 3 and fixedly connected with the storage bin assembly 3. The air outlet elbow 315 is sealed and communicated with the pipeline (not shown in the figure) of the gas path system 10, so as to convey the gas in the air outlet elbow 315 to the Roots blower air inlet of the power vehicle 100. Each Roots blower is connected with the air outlet elbow 315 through a high negative pressure pipeline and the storage bin assembly 3 of the material storage vehicle 200 and the trailer vehicle 300, so as to realize material suction. Since the air outlet elbow 315 is fixedly connected with the storage bin assembly 3, after the storage bin assembly 3 is installed in place, under the action of its own gravity, the air outlet elbow 315 is pressed and contacted with the flexible sealing device 104' (i.e. rubber sealing strip) on the pipeline connecting seat 105' of the gas path system 10, and the sealing effect is reliable. The gas passes through the pipeline system and finally enters the Roots blower of the power vehicle 100, and the airflow is filtered again, and the clean air is discharged into the atmosphere.

[0205] Continuing to refer toFigure 8 In some embodiments, the flow guide assembly 37 comprises an air inlet 371 and an air outlet 372. The air inlet 371 of the flow guide assembly 37 is located at the top of the bin 31, and the air outlet 372 of the flow guide assembly 37 is located at the bottom or middle-lower part of the bin 31, and the air outlet 372 of the flow guide assembly 37 is in communication with the communication port 3162. The position of the feed inlet 303 is lower than the air inlet 371 of the flow guide assembly 37. The feed inlet 303 of the bin 31 is arranged to be lower than the air inlet 371 of the flow guide assembly 37, so that the buried material is sucked into the bin 31, the solid material sinks, and the gas overflows into the dust removal bin 32. The solid material is not easy to be brought into the dust removal bin 32, the use volume of the bin 31 is improved, the utilization rate of the bin 31 is high, more material can be stored, and the storage space of the bin 31 is maximized.

[0206] Referring to Figure 7 The bin 31 of the storage bin assembly 3 is provided with a feed inlet control assembly 35, specifically, each feed inlet 303 is provided with a valve. In addition, the bin 31 comprises a material observation window 314 for facilitating observation of the material level. The first air duct flow guide device 316, the second air duct flow guide device 317, and the combined flow air duct 318 are arranged inside the bin 31.

[0209] In some embodiments, a plurality of dust removal filters 323 are installed in each dust removal bin 32, and each dust removal filter 323 is vertically installed inside the dust removal bin 32. Each dust removal filter 323 is configured to be started and stopped simultaneously.

[0210] In some embodiments, the storage bin assembly 3 further comprises a blowing device 322, which is installed inside the dust removal bin 32 and arranged adjacent to the dust removal filter 323 for blowing and cleaning the dust removal filter 323. During the operation of the storage vehicle 200, the dust removal filter 323 is periodically back-flushed to prevent clogging of the dust removal filter 323 and ensure the dust removal effect.

[0211] In some embodiments, the storage bin assembly 3 further comprises a confluence air duct 318, which is in communication with the outlets of the two dust removal bins 32 to converge the clean fluid after dust removal of the two dust removal bins 32. The storage bin assembly 3 integrates the functions of storage, dust removal, unloading, etc., and has a high degree of integration. The air duct is divided and converged by the flow guide assembly 37 and the confluence air duct 318, which improves the gas filtration effect, effectively realizes gas-solid separation, reduces dust content, and reduces environmental pollution. The flow path of the airflow is divided and then converged, which increases the filtration distance of the airflow, ensures sufficient contact of the airflow with the dust removal filter 323, and realizes the best effect of gas-solid separation.

[0212] In some embodiments, the storage vehicle 200 further comprises a power generation and supply system 4, which is installed on the vehicle frame assembly 2 and is configured to generate power to supply power to the storage vehicle 200 and the pipe trailer 300 located upstream of the storage vehicle 200.

The control box 41 is electrically connected with the generator set 42 to control the working parameters of the generator set 42. The cable reel 43 is used to wind the cable, and the power generated by the generator set 42 is transmitted to the pipe trailer 300 through the cable. One storage vehicle 200 can supply power to multiple pipe trailers 300 at the same time, ensuring that the pipe trailer 300 at the front end can work continuously for a long time.

[0214] In some embodiments, the storage vehicle 200 further comprises a lighting device installed on the vehicle frame assembly of the storage vehicle. The power of the lighting device comes from the power generation and supply system 4 installed on the storage vehicle 200, and the lighting device realizes rescue at night or in areas with poor light.

[0215] In some embodiments, the storage vehicle 200 further comprises a plurality of 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 arranged on both sides of the storage vehicle 200 in the width direction, the third camera 57 is arranged at the tail of the storage vehicle 200, and the fourth camera 58 is arranged at the head of the storage vehicle 200. Each camera is in communication connection with the controller arranged on the power vehicle 100, and the image information within the 360° range of the environment around the storage vehicle 200 is obtained through the camera, so that the storage vehicle 200 can work safely.

[0216] In some embodiments, the storage vehicle 200 further comprises a storage vehicle control system 5 installed on the vehicle frame assembly 2, which mainly provides control, detection and protection, and remote control functions. The storage vehicle 200 is an unmanned vehicle, which walks and controls the operation parameters in a remote control mode. The storage vehicle control system 5 comprises an electric control box 53, a negative pressure detection sensor 55, etc. to realize the functions of remote control and detection.

[0217] In some embodiments, the stock car 200 further comprises an engine system 7 installed at the bottom of the frame assembly 2. The engine system 7 provides power for the whole vehicle operation. The engine system 7 is arranged in a longitudinal manner, between the two track assemblies, fixed on the frame, with good symmetry, low center of gravity, and good vehicle stability.

[0218] In some embodiments, the stock car 200 further comprises an air path system 10 installed on the storage bin assembly 3 to achieve dust removal inside the bin 31; the air path system 10 is also drivingly connected with the feed inlet control assembly 35 to drive the feed inlet control assembly 35 to move, thereby achieving the opening and closing of the feed inlet 303.

[0219] The air path system 10 comprises an air compressor assembly 101', a pipeline assembly 102', a gas tank assembly 103', a flexible sealing device 104', and a pipeline connecting seat 105'.

[0220] Referring to Figure 6 , the air compressor assembly 101' is arranged outside the storage bin assembly 3 and is arranged side by side with the storage bin assembly 3. The outer cover of the air compressor assembly 101' is provided with a coaming assembly 11. The coaming assembly 11 is made of multiple plates spliced and welded. The coaming assembly 11 plays a role in protecting the air compressor assembly 101'.

[0221] The air compressor assembly 101' is in gas communication with the blowing device 322 through the pipeline assembly 102', and the air compressor assembly 101' is used to provide compressed gas required for blowing for the blowing device 322. The air path system 10 is responsible for providing gas source for the dust removal system pulse back blowing, plug valve and lighting equipment and other gas equipment.

[0222] Referring to Figures 11 to 15 , the pipe trailer car drives the suction pipeline assembly to directly perform suction operation, realizing position control of the suction head. The specific implementation of the pipe trailer car is introduced below.

The second suction pipeline support frame is fixed on the arm support assembly 3022 through bolts, and the first suction pipeline support frame 30211 is fixed on the rotating platform 3021 through bolts, which is used for auxiliary fixing of the suction pipeline 30224.

[0228] Referring to Figure 13 Each suction pipeline support frame includes a support hole b, and the suction pipeline 30224 passes through the support hole b. The first rotating drive 30212 is installed on the mounting base 3020, and the first rotating drive 30212 is engaged with the first rotating support 30112 of the pipeline truck chassis assembly 3001, referring to Figure 12 The first rotating drive 30212 is configured to drive the mounting base 3020 to rotate relative to the first rotating support 30112. The first rotating drive 30212 specifically adopts a motor. The first rotating drive 30212 drives the mounting base 3020 to rotate alone, and does not provide power for the amplitude, the second rotation and the walking introduced below, so the first rotating drive 30212 can select a small size product.

[0237] Continuing to refer to Figure 13 The arm assembly 3022 further comprises a second rotary driver 30225, which is specifically installed on a second rotary support 30227 through an end motor mounting seat 30226. The second rotary driver 30225 is connected with a hydraulic pump via a hydraulic valve group 30422; the second rotary driver 30225 is drivingly connected with a suction head 30229 to drive the suction head 30229 to rotate relative to a suction pipeline 30224. The suction head 30229 is installed on the second rotary support 30227. The suction head 30229 is in communication with the suction pipeline 30224 through a pipeline connector 30228.

[0238] The second rotary driver 30225 can adopt a motor, which separately drives the suction head 30229 to rotate, so that a small-sized motor can be selected, realizing light weight of the tow pipe vehicle 300. In the suction operation process, the second rotary driver 30225 drives the suction head 30229 to rotate, improving the flexibility of the suction end, the rotation angle is large, multi-angle suction rescue is realized, and the rescue efficiency is improved.

[0239] The second rotary support 30227 is fixed on the arm assembly 3022 through bolts, the end motor mounting seat 30226 is fixed on the arm assembly 3022 and the second rotary support 30227 through bolts, and the second rotary driver 30225 is fixed on the end motor mounting seat 30226 and engaged with the second rotary support 30227 through bolts, for rotating the suction head 30229 to break up the cemented material, improving the suction efficiency. The second rotary driver 30225 can specifically adopt a motor, which separately drives the suction head 30229 to rotate, so that a small-sized motor can be selected, which is conducive to realizing light weight of the tow pipe vehicle 300. The second rotary driver 30225 realizes the rotatability of the suction head 30229. The rotation of the suction head 30229 can assist in breaking up the cemented material, making the suction more easy, making the adaptability to the complex rescue environment and the cemented material suction stronger, the suction effect better, and the suction rescue efficiency higher.

[0240] The multi-degree-of-freedom arm support structure form, multi-section arm amplitude adjustment, can multi-angle, multi-direction for buried object suction rescue, end of the rotary broken loose function, improve the adaptability and efficiency of complex rescue environment.

[0241] Referring to Figure 13 and Figure 14 The towed pipe truck 300 further comprises a power system 3004, which provides matched power for each movement of the towed pipe truck 300. The power system 3004 comprises a driving motor, a hydraulic pump and a hydraulic valve group 30422. The driving motor, the hydraulic pump and the hydraulic valve group 30422 form a module, which is referred to as a motor-pump group 30424. The driving motor is electrically connected with the power supply system of the storage truck 200, the driving motor is drivingly connected with the hydraulic pump, the hydraulic pump is communicated with the first amplitude driving member 30221, the second amplitude driving member 30222 and the third amplitude driving member 30223 through the hydraulic valve group 30422, so as to supply oil to the first amplitude driving member 30221, the second amplitude driving member 30222 and the third amplitude driving member 30223; the hydraulic pump is also communicated with the first slewing driving member 30212 through the hydraulic valve group 30422, so as to provide slewing power of the whole vehicle to the first slewing driving member 30212.

[0242] The hydraulic power of the towed pipe truck 300 comes from the hydraulic pump installed on the towed pipe truck 300, which is driven by the driving motor, so that a long hydraulic pipeline is not needed. Even when the power supply of the driving motor cannot be supplied, power supply can be realized through the rechargeable backup battery system to be introduced later, so that the towed pipe truck 300 can operate independently, thereby improving the timeliness of rescue.

[0244] The electric energy of the towed pipe truck 300 comes from the storage truck 200, and the power supply system 4 of the towed pipe truck 300 and the storage truck 200 are electrically connected through a cable. The storage truck 200 collects the material sucked by the towed pipe truck 300 and provides driving power for the towed pipe truck 300 through the power supply system 4 and the cable reel, so that the light weight of the towed pipe truck 300 can be further realized.

[0245] The power system 3004 adopts a driving motor to drive a hydraulic pump to work, and then the hydraulic pump distributes hydraulic oil to each working joint through the hydraulic valve group 30422 to realize the following four actions of the pipe trailer 300: whole vehicle walking, amplitude change of the boom assembly 3022, rotation of the boom assembly 3022, and rotation of the suction head 30229 itself. The pipe trailer 300 is provided with an oil tank, and the oil used by each hydraulic component comes from the oil tank, so the hydraulic pipeline is very short, and the disadvantages of the pipe trailer 300 dragging a long hydraulic pipeline are greatly reduced, and the load capacity of the pipe trailer 300 is reduced. The form of the motor-driven hydraulic pump group does not need to set too many hydraulic pipelines, so that the pipe trailer 300 is small in size and light in weight, and is more flexible and higher in work efficiency when working in a narrow space. The motor-driven hydraulic pump group provides power for chassis walking and whole machine action, and the plug-in operation form ensures the endurance of the pipe trailer 300.

However, in order to realize emergency rescue, the power system 3004 further includes a rechargeable backup battery system, which is electrically connected with the driving motor, so as to provide emergency rescue power when the driving motor is not electrically connected with the power supply system of the storage car 200. The emergency power module is provided, and once the remote power supply fails, the emergency power module can be quickly switched to power supply, so as to ensure the timeliness of the suction rescue. The emergency power module is provided to prevent the remote power supply from failing, and the emergency power module can be quickly switched to power supply, so as to ensure the timeliness of the suction rescue.

The control unit 30414 is mounted on the slewing platform 3021. The control unit 30414 is fixed on the slewing platform 3021 by bolts, and each action is implemented by controlling the hydraulic system of the pipe trailer. The posture detection assembly 30417 is mounted on the slewing platform 3021, and is configured to detect the posture of the boom assembly 3022; the control unit 30414 is electrically connected with the posture detection assembly 30417. The gas concentration detection element 30418 is mounted on the boom assembly 3022 to detect the gas concentration around the boom assembly 3022.

[0250] According to needs, only one of the posture detection assembly 30417 and the gas concentration detection element 30418 can be provided, or both of them can be provided.

[0251] Continuing to refer to Figure 13 and Figure 14 , the pipe trailer 300 further comprises a video monitoring system 3005, which comprises a video processing module 3051, a camera assembly and a voice communication module 3054; the video processing module 3051 is mounted on the slewing platform 3021 and electrically connected with the camera assembly; the camera assembly is mounted at different positions of the slewing boom assembly 3002 to detect images of different areas; the video processing module 3051 is electrically connected with a display located on the power vehicle 100; and the voice communication module 3054 is electrically connected with a controller of the power vehicle 100 to realize remote communication between rescue personnel and rescued personnel.

[0252] Continuing to refer to Figure 14 , the camera assembly comprises a pan-tilt camera 3052 and a dome camera 3053. The pan-tilt camera 3052 is mounted on the coaming 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.

[0253] The video processing module 3051 is fixed on the slewing platform 3021 by bolts, and the pan-tilt camera 3052, the dome camera 3053 and the voice communication module 3054 are respectively fixed on the coaming assembly 3003 and the boom assembly 3022 by bolts.

[0254] The pipe trailer 300 is provided with a wireless remote control unit 30416, a video voice system, a posture detection assembly 30417 and a gas concentration detection element 30418. The video voice system can observe the on-site rescue situation in real time and conduct voice communication with the rescued personnel. The posture detection assembly 30417 assists in controlling the posture of the pipe trailer suction rescue equipment to prevent the whole machine from tipping over.

[0255] The video monitoring system 3005 provides on-site visual monitoring pictures and voice intercom functions for the equipment, realizes remote visual voice intercom operation, and can realize real-time understanding of the dynamic of the rescue site.

[0256] The posture detection assembly 30417 is fixed to the slewing platform 3021 by bolts and is used for detecting the posture of the whole machine. When the X-axis inclination value is greater than S1 or the Y-axis inclination value is greater than S2, the control unit 30414 receives the signal of the posture detection assembly 30417 and processes and sends it to the buzzer. The buzzer starts to beep after receiving the signal, reminding the rescue personnel that the whole machine may be in danger of tipping over and needs to be adjusted to protect the safety of the equipment. The X-axis is the walking direction of the pipe trailer 300. The X-axis inclination refers to the angle between the walking direction 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 inclination refers to the angle between the Y-axis of the pipe trailer 300 and the horizontal plane.

[0257] The posture detection assembly 30417 can monitor the posture of the whole pipe trailer 300, so that the rescue personnel can remotely and in real time understand the dynamic of the rescue site, improving the reliability and reliability of the rescue; and when the posture detected by the posture detection assembly 30417 exceeds the limited value, the pipe trailer 300 will issue an alarm to prevent tipping over and make the suction operation more safe and reliable.

[0258] The gas concentration detection element 30418 is fixed to the boom assembly 3022 by bolts and is used for real-time monitoring of the concentration of dangerous gases at the rescue site and timely selection of the optimal rescue scheme. Once the gas concentration exceeds the standard, an alarm will be prompted to ensure the safe and smooth progress of the rescue work.

[0259] A multi-directional video monitor (not shown in the figure) is arranged on the pipe trailer 300 at the rescue end, and a large-size display screen (not shown in the figure) is integrated on the pipe trailer remote controller, which can clearly display the audio and video situation at the rescue end in real time.

[0260] The display (not shown in the figure) of the pipe trailer remote controller can display the main parameter situation and alarm information of the power car 100, the storage car 200 and the pipe trailer 300, so that the operator can comprehensively understand the key system situation of each sub-car in the suction circuit.

[0261] The pipe trailer remote controller has the functions of fan control, storage car 200 unloading control, pipe trailer 300 self-action control and pipe switching, and can realize control over the whole suction circuit to ensure the safety of the operation.

[0262] The actual application scene is introduced as follows.

[0263] The working process of the rescue suction unit is as follows: the whole unit needs three vehicles to work simultaneously to realize multi-vehicle cooperative operation, and the connection form is as shown in Figure 1 When carrying out burial rescue, the layout of the unit is carried out according to the rescue site condition:

[0264] If the rescue site condition allows, the storage vehicle 200 is as close to the pipe trailer 300 as possible, and the power vehicle 100 is parked in the periphery of the rescue, so as to reduce the interference to the rescue site.

[0265] If the rescue site condition does not allow large heavy load equipment to approach, only the pipe trailer 300 enters the site, and the power vehicle 100 and the storage vehicle 200 are away from the rescue site to ensure the safety of the rescue site.

[0266] Therefore, the pipe length between the power vehicle 100, the storage vehicle 200 and the pipe trailer 300 is flexible, which is planned according to the site layout condition. The final purpose is to quickly suck and remove the buried object above the buried person to avoid injury and improve the rescue safety and rapidity.

[0267] The above technical scheme, the power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are each independent moving unit, each vehicle has independent power (engine, battery or motor power), realizes self walking, provides power for its own operation part; the power vehicle 100 with large size and high noise is arranged in the periphery of the rescue area; the light and flexible pipe trailer 300 replaces the rescue personnel to enter the core area of the rescue; the power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are connected by pipes, the storage vehicle 200 is arranged flexibly between the power vehicle 100 and the pipe trailer 300 to realize rapid unloading, under the premise that large equipment cannot enter the rescue area, the rescue can also be carried out normally by using the equipment, and the rescue efficiency is extremely high. Each vehicle of the unit has an independent controller to realize its own action control, the controllers are connected through CAN bus communication technology to realize data sharing, the communication mode can be cable connection mode or wireless communication, through the bus communication technology, multi-point cooperative operation is realized, and then multi-point synchronous rescue is realized to improve the rescue efficiency.

[0268] The power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are each provided with an independent controller to realize its own state monitoring and operation control, and the controllers of the vehicles are communicated through CAN bus communication technology to realize information sharing.

[0269] In order to improve the safety of rescue personnel, in addition to the power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are controlled by remote controllers, and the power vehicle 100 is controlled by the vehicle body console. The power vehicle 100, the storage vehicle 200 and the pipe trailer 300 are each provided with a display, and can realize parameter setting, state display and other functions. The pipe trailer remote controller at the rescue end has fan control function, storage vehicle 200 unloading control function, pipe trailer 300 self-action control and pipe switching function, and can realize control of the entire suction circuit.

[0270] In some embodiments, the power vehicle 100 is also provided with an oil level sensor (not shown in the figure) and a temperature sensor (not shown in the figure) for detecting the fan inlet temperature and the key bearing temperature. The storage vehicle 200 is also provided with a water level detection sensor, an oil level sensor and an oil temperature sensor (not shown in the figure). The pipe trailer 300 is also provided with a water level detection sensor and an inclination detection sensor (not shown in the figure). The alarm information of each of the above sensors can be displayed on the display of the pipe trailer remote controller, so that the operator can fully understand the key system conditions of each vehicle in the suction circuit.

[0271] Referring to Figures 16 to 20 , the rescue suction unit operation method will be introduced below.

[0272] Referring to Figure 16 and Figure 17 , the rescue suction unit provided by the embodiment of the present application is described by taking the following structure as an example. It can be understood that the following is only an example and does not represent a limitation on the number of components.

[0273] The rescue suction unit takes one power vehicle 100, two storage vehicles 200 and three or six pipe trailers 300 as an example. Each vehicle has independent power, high single-machine flexibility and good maneuverability, and meets the requirements of rapidity and safety of rescue. One power vehicle 100 is equipped with two fans, i.e. a first Roots fan 1033 and a second Roots fan 1042.

[0274] Referring to Figure 16 , one power vehicle 100 can be connected to two storage vehicles 200 at most, and each storage vehicle 200 is connected to three pipe trailers 300, i.e. forming a 1+2+6 arrangement, wherein 1 represents one power vehicle 100, 2 represents two storage vehicles 200, and 6 represents six pipe trailers 300. The number of pipe trailers 300 connected in this way is the largest, and this mode is also called a maximum rescue point mode. This mode can realize simultaneous operation of six pipe trailers 300 at six different operation sites at most.

[0275] The connected fan is set on the storage vehicle display, and the connected storage vehicle 200 and corresponding storage vehicle 200 inlet are set on the pipe trailer display. For example, the corresponding connection mode of a pipe trailer 300 is as follows: first Roots fan 1033 + storage vehicle 200A + inlet A2 + pipe trailer 300. After the connection mode is selected, the corresponding second electromagnetic valve 1068 and first electromagnetic valve 1067 are automatically opened, the inlet A2 of the storage vehicle 200A is automatically opened, and the remaining valves remain closed, thereby establishing a complete suction circuit. Each pipe trailer 300 selects the corresponding storage vehicle 200 and storage vehicle 200 inlet on its own display, and selects the corresponding fan and pipeline on the storage vehicle 200 display, thereby realizing the corresponding suction circuit of each pipe trailer 300.

[0276] When the suction medium is too viscous, the suction resistance is too large, or the suction power of a certain rescue point needs to be strengthened during rescue, the first Roots fan 1033 and the second Roots fan 1042 can be combined to perform suction operation through the same pipe trailer 300. At this time, it needs to be selected whether to pass through the channel of the first Roots fan 1033 or the channel of the second Roots fan 1042, so as to confirm the suction circuit. After the channel is selected, the valve of the combination device is automatically opened and closed.

[0277] A material level sensor (not shown in the figure) is installed on the storage bin of the storage vehicle 200. When the material level of the storage bin is detected to be full, the storage vehicle remote controller and the pipe trailer remote controller alarm at the same time, the operator performs unloading operation, the pipe trailer 300 loses suction power during unloading, and the suction operation continues after the unloading operation is completed.

[0278] Referring to Figure 17 , considering the actual situation, the storage vehicle 200 needs to be unloaded after being full of material. During unloading, the storage vehicle 200 cannot continue to perform suction operation. In some cases, the rescue efficiency is required to be extremely high, and the rescue operation needs to be uninterrupted. The continuous operation mode shown in Figure 17 can be used. In this mode, after one storage vehicle 200 is full of material, another storage vehicle 200 is switched to a suction storage state, so that the pipe trailer 300 can continuously perform suction operation without stopping. It should be noted that the switching time of the two storage vehicles 200 is short, and the switching time can be ignored, so the pipe trailer 300 is considered to continuously perform suction operation.

[0279] Continuing to refer to Figure 17The total of three pipe trailer 300, which is in communication with the first storage truck 200, also in communication with the second storage truck 200. After the first storage truck 200 filled with material, the second storage truck 200 switch to suction state. After the second storage truck 200 filled with material, the first storage truck 200 switch to suction state. By controlling the valve position of the three-way valve can achieve the above switching. So arranged that two storage trucks 200 alternate operation, to ensure the continuity of the front end pipe trailer 300 suction operation, thereby greatly improving the efficiency of rescue suction, to avoid the waste of energy of the power car 100.

[0280] Referring to Figure 17 And Figure 18 The first Roots blower 1033 of the power car 100 is connected to the exhaust port of the storage truck 200A, the second Roots blower 1042 is connected to the exhaust port of the storage truck 200B, the pipe trailer 300 is connected to the three-way valve, and the two split ports of the three-way valve are connected to the material inlet A1 of the storage truck 200A and the material inlet B1 of the storage truck 200B through the hose.

[0281] Referring to Figure 17 The three-way valve connects two storage trucks 200 with the same pipe trailer 300. The three-way valve is a pneumatic or electric control valve. When the three-way valve is not powered, the pipe trailer 300 is connected to the material inlet A1 of the storage truck 200A; when the three-way valve is powered, the pipe trailer 300 is connected to the material inlet B1 of the storage truck 200B, and the control of the three-way valve is controlled by the storage truck 200 controller. In order to simplify the selection interface and facilitate operation, the material inlet of each pipe trailer 300 connected to the storage truck 200A needs to be consistent. In this connection mode, a maximum of 3-point synchronous suction operation can be achieved.

[0282] The above-mentioned three-way valve can be integrated on the pipe trailer 300, or integrated on the storage truck 200, or arranged as an independent unit on the pipeline.

[0283] After the pipeline is connected, the controller and the display are set to the cooperative operation mode as follows:

[0284] Referring to Figure 17The corresponding three-way reversing valve, the connected storage vehicle 200, and the corresponding storage vehicle 200 inlet are arranged on the display of the pipe trailer. For example, the connection mode of a pipe trailer 300A is as follows: storage vehicle 200B + inlet B3 + three-way reversing valve A + pipe trailer 300A. After the connection mode is selected, the three-way reversing valve A is powered on, the pipe trailer 300A is connected to the storage vehicle 200B, the inlet B3 of the corresponding storage vehicle 200B is automatically opened, and the remaining valves are kept in a closed state. Each pipe trailer 300 selects the corresponding three-way reversing valve, storage vehicle 200, and storage vehicle 200 inlet on its own display, thereby realizing the corresponding suction circuit of each pipe trailer 300.

[0285] In this mode, the first Roots blower 1033, the second Roots blower 1042, or the double blower combined operation can be selected according to the type and suction distance of the suction material on site. The five valves of the blower combined device automatically realize on-off control according to the selected storage vehicle 200 and blower. The specific implementation is as follows:

[0286] Referring to Figure 17 and Figure 18 When the pipe trailer 300 selects the storage vehicle 200A, the first suction section has the following connection modes: mode 1, the first Roots blower 1033 is started, the first electromagnetic valve 1067 and the second electromagnetic valve 1068 are opened, and the other electromagnetic valves are closed; mode 2, the second Roots blower 1042 is started, the fourth electromagnetic valve 10610, the fifth electromagnetic valve 10611, and the first electromagnetic valve 1067 are opened, and the other electromagnetic valves are closed; mode 3, when the first Roots blower 1033 and the second Roots blower 1042 are both started, the second electromagnetic valve 1068, the fourth electromagnetic valve 10610, the fifth electromagnetic valve 10611, and the first electromagnetic valve 1067 are opened, and the remaining valves are in a closed state.

[0287] Referring to Figure 17 and Figure 18 When the pipe trailer 300 selects the storage vehicle 200B, the first suction section has the following connection modes: mode 1, the first Roots blower 1033 is started, the second electromagnetic valve 1068, the fifth electromagnetic valve 10611, and the third electromagnetic valve 1069 are opened, and the other electromagnetic valves are closed; mode 2, the second Roots blower 1042 is started, the fourth electromagnetic valve 10610 and the third electromagnetic valve 1069 are opened, and the other electromagnetic valves are closed; mode 3, when the first Roots blower 1033 and the second Roots blower 1042 are both started, the second electromagnetic valve 1068, the fourth electromagnetic valve 10610, the fifth electromagnetic valve 10611, and the third electromagnetic valve 1069 are opened, and the remaining valves are in a closed state.

[0288] According to different field requirements, the rescue point maximization mode or the continuous operation mode can be selected, and multiple pipe towing vehicles 300 can be synchronized to carry out rescue operations in each mode, so that multiple machines can simultaneously rescue in a large area of disaster site, and the rescue efficiency is greatly improved.

[0289] Referring to Figure 19 and Figure 20 , the embodiment of the present application provides a rescue suction unit operation method, comprising the following steps:

[0290] Step S100, confirming the working mode of the rescue suction unit.

[0291] The working mode of the rescue suction unit includes a rescue point number maximization working mode and an uninterrupted operation mode.

[0292] Referring to Figure 16 and Figure 19 , the rescue point number 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 towing vehicles 300, so that two storage vehicles 200 respectively perform suction operation on three pipe towing vehicles 300.

[0293] In Figure 19 , the judgment logic is as follows: referring to Figure 19 the left half, in the rescue point number maximization working mode, the working fan is determined first. There are three cases: the first Roots fan 1033 works alone, the second Roots fan 1042 works alone, and the first Roots fan 1033 and the second Roots fan 1042 work together.

[0294] The power vehicle 100 includes a first flow inlet and a second flow inlet; the storage vehicle 200 includes two, and each storage vehicle 200 includes three feed inlets. According to needs, more feed inlets can also be provided. When in the rescue point number maximization working mode, the number of pipe towing vehicles 300 is six, the first flow inlet is connected to one of the storage vehicles 200, the second flow inlet is connected to the other storage vehicle 200, and each storage vehicle 200 is connected to three pipe towing vehicles 300.

[0295] In the rescue point number maximization working mode, the connection relationship between the storage vehicle 200 and the pipe towing vehicle 300 is determined, as shown in Figure 18 When the first Roots fan 1033 works alone, the first suction section between the storage vehicle 200 and the power vehicle 100 is first connected: the first electromagnetic valve 1067 is opened, and the second electromagnetic valve 1068 is opened; then according to the determined storage vehicle 200, the feed inlets of the storage vehicle 200 are opened. During the suction process, it is judged in real time whether the storage bin of the storage vehicle 200 is full, and if it is full, the material is unloaded. If the pressure in the storage bin of the storage vehicle 200 is too high, the pressure can be reduced by opening the exhaust valve of the corresponding fan.

[0296] 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.

[0297] 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.

[0298] 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.

[0299] by Figure 19 The leftmost path in the uninterrupted operation mode details the judgment logic.

[0300] 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 solenoid 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 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.

[0301] Step S200, according to the working mode, determine the need for suction storage job of the storage truck 200, the fan and the trailer truck 300.

[0302] In the maximum working mode and uninterrupted working mode, the logic of the storage truck 200, the fan and the trailer truck 300 is different, which has been described in detail above. In the two working modes, different judgment logic is adopted, and the control is more accurate and efficient.

[0303] Step S300, the suction flow path of the storage truck 200 is connected; the suction flow path includes a first suction section from the storage truck 200 to the power car 100 and a second suction section from the storage truck 200 to the trailer truck 300.

[0304] The air inlet of the power car 100 and the air outlet of the storage truck 200 are connected by a suction hose, and the material inlet of the storage truck 200 and the pipeline joint of the trailer truck 300 are connected by a suction hose. In addition, a communication line between the power car 100, the storage truck 200 and the trailer truck 300 is built by wired or wireless mode, so as to establish data connection.

[0305] Step S400, start the power car 100 located in the first suction section to perform suction work.

[0306] Combined Figure 18 , the respective on state is described in detail.

[0307] When the first Roots blower 1033 works alone and the first storage truck 200 stores material, the first electromagnetic valve 1067 and the second electromagnetic valve 1068 on the first suction section between the first storage truck 200 and the first Roots blower 1033 are turned on.

[0308] When the second Roots blower 1042 works alone and the first storage truck 200 stores material, the first electromagnetic valve 1067, the fourth electromagnetic valve 10610 and the fifth electromagnetic valve 10611 on the first suction section between the first storage truck 200 and the second Roots blower 1042 are turned on.

[0309] When the first Roots blower 1033 works alone and the second storage truck 200 stores material, the third electromagnetic valve 1069, the second electromagnetic valve 1068 and the fifth electromagnetic valve 10611 on the first suction section between the second storage truck 200 and the first Roots blower 1033 are turned on.

[0310] When the second Roots blower 1042 works alone and the second storage truck 200 stores material, the third electromagnetic valve 1069 and the fourth electromagnetic valve 10610 on the first suction section between the second storage truck 200 and the second Roots blower 1042 are turned on.

[0311] 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.

[0312] 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.

[0313] 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.

[0314] 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.

[0315] In some embodiments, the rescue suction unit operation method further includes the following steps:

[0316] Step S500: Determine whether the hopper of the storage car 200 is full.

[0317] Step S600: If the storage hopper of the storage trolley 200 is full, unload the storage trolley 200.

[0318] 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.

[0319] In some embodiments, the rescue suction unit operation method further includes the following steps:

[0320] Step S700, judging whether the negative pressure in the hopper of the storage vehicle 200 exceeds a set value.

[0321] Step S800, if the negative pressure in the hopper of the storage vehicle 200 exceeds the set value, exhausting the fan in the same suction flow path as the storage vehicle 200.

[0322] The step S500 and the step S700 can be performed simultaneously, sequentially or alternately.

[0323] A pressure sensor is installed on the top of the hopper of the storage vehicle 200 to monitor the negative pressure in the hopper in real time. An unloading valve is installed on the inlet pipeline of each fan of the power vehicle 100, which is a pneumatic or electric valve. When the pressure in the working hopper exceeds the set value, the unloading valve corresponding to the fan inlet is opened to prevent the suction system pressure value from being too high and prevent the suction end of the trailer vehicle 300 from being too high, thereby causing harm to the rescued object.
