[0002] China has a vast territory with criss-crossing rivers and lakes. Pumping stations are important infrastructure in irrigation and drainage of water conservancy projects and urban flood control and drainage, undertaking tasks such as agricultural and urban irrigation and drainage, flood control and waterlogging drainage, and water supply for industrial and agricultural production and urban and rural residents' living. However, in case of extremely heavy floods or droughts, the fixed pumping stations designed according to standards may not be able to work properly due to too high or too low water levels. At this time, it is impossible and uneconomical to build temporary pumping stations, which usually cause heavy losses to the country and people's lives and property. With the development of urban construction, the urban environment is becoming more and more complex. In some low, short and narrow environments (such as narrow streets, underground passages, underground garages, subway stations) or places with complex road conditions, the existing pump trucks cannot enter and operate normally and cannot play any role

One end of the link mechanism (10) is movably connected with the crawler chassis (8) and the lower part of the carriage (7) through a pin shaft, and the other end of the link mechanism (10) is movably connected with the middle part of the carriage (7). A telescopic pipe (1) is arranged on the carriage (7), and a control device (4) is installed on the crawler chassis (8) on the side of the telescopic pipe (1)

[0004] In this patent, the water pump of this patent adopts a drainage pump with a large flow rate. The drainage pump with a large flow rate has the disadvantage of low lift, which makes the mobile pumping station of this patent need to lay a lot of water hoses and pressurizing devices, which greatly affects the traffic conditions at the operation point and the timeliness of emergency rescue. Moreover, when the water hoses are in the retracted state, if there is no appropriate storage facility, they will occupy a large amount of space. In case of emergency, the time consumed in searching for and sorting the water hoses will affect the rescue efficiency Utility Model Content

[0050] Please refer to Figures 1 to 5The present embodiment provides a drainage robot, including a chassis 1 with a walking mechanism, a drainage device 2 and a winch 3. The drainage device 2 includes a fire pump 21 and a power mechanism. The fire pump 21 is arranged on the chassis 1. The power mechanism includes a motor 22. The motor 22 is arranged on the chassis 1 and is transmission-connected to the fire pump 21. The winch 3 includes a bracket 31 and a drum 32. The bracket 31 is arranged on the chassis 1. The drum 32 is provided on the bracket 31. The drum 32 can rotate relative to the bracket 31, and the drum 32 can be wound with a water hose.

[0051] The drainage robot is specially designed to perform drainage tasks in various complex terrains, such as urban waterlogging, mine waterlogging, tunnel waterlogging and other environments. It can quickly drain water in floods or emergencies, and has mobility and remote operation capabilities. The hose material is selected from pressure-resistant and wear-resistant synthetic materials to ensure that it will not break under high pressure, and it is light and easy to carry.

[0052] The bracket 31 is the basic structure of the winch 3, and its main function is to support and fix the drum 32 to ensure the stability of the winch 3 during use. The bracket 31 needs to be firmly connected to the robot chassis 1, usually by bolts or welding, to ensure that the winch 3 will not loosen or fall off when the robot moves. The drum 32 needs to be able to rotate relative to the bracket 31, which is usually achieved through bearings, and the drum 32 is driven to rotate relative to the bracket 31 manually or electrically.

[0053] Different from the prior art, the above technical solution has the following beneficial effects:

[0054] By integrating the winch 3 on the robot chassis 1, the winch 3 is operated to release the water hose during use. After the water hose is unfolded, its port is connected to the water outlet or water inlet of the fire pump 21. When storing, the water hose can be wound on the winch 3 for easy storage. The orderly water hose management reduces a series of hazards caused by the random placement of water hoses. In an emergency, it can respond quickly, speed up drainage, improve rescue efficiency, and improve the efficiency and convenience of drainage operations.

[0055] See also Figure 3 When designing a drainage robot, considering that it needs to move in various complex environments, including narrow lanes or pipes, the size and layout of the robot become key considerations in the design. In this embodiment, the winch 3 is located on the left or right side of the motor 22. The fire pump is large in size, while the motor 22 is relatively small. The winch 3 is cleverly designed to be on the left or right side of the motor 22, avoiding the waste of the robot's internal space and making the entire device more compact.

[0056] Further, there are two winches 3, such as Figure 3As shown, two winches 3 are arranged side by side and are located on the left and right sides of the motor 22, which can effectively utilize the relatively large space left around the motor 22. This layout not only maximizes the functionality of the robot, but the dual winch 3 configuration enables the robot to handle two water hoses simultaneously.

[0057] Please refer to Figure 2 , in this embodiment, the fire pump 21 is located at the front end or the middle end of the chassis 1, and the winch 3 is located at the rear end of the chassis 1. This enables the fire pump 21 to be closer to the water source or the drainage point, and also helps the operator to more intuitively judge the position of the fire pump 21 when deploying the robot. The winch 3 is located at the rear end of the robot, forming a layout that echoes the front and back with the fire pump 21. Such a design facilitates the natural extension and deployment of the water hose and avoids the entanglement of the water hose on the robot body.

[0058] Please refer to Figure 2 and Figure 4 , in this embodiment, the fire pump 21 is located at the front end or the middle end of the chassis 1. The fire pump 21 is provided with a water inlet channel 2111 and a water outlet channel 2112. The water inlet of the water inlet channel 2111 faces the front of the chassis 1 (the driving direction of the drainage robot is the front direction), and the water outlet channel 2112 passes through the chassis 1 and extends to the rear of the chassis 1. The water outlet of the water outlet channel 2112 faces the rear of the chassis 1. The design with the water inlet facing the front of the chassis 1 enables the fire pump 21 to access the water source more directly when the robot moves forward. The water outlet channel 2112 leads out from the fire pump 21 and passes through the rear part of the chassis 1 to ensure that the water flow can be smoothly discharged from the rear of the robot.

[0059] In this embodiment, the water inlet of the water inlet channel 2111 faces the front of the chassis 1, and the water outlet of the water outlet channel 2112 faces the left side and / or the right side of the chassis 1. Figure 6 、 Figure 7 shows that there are a total of four water outlet channels 2112. The water outlets of two water outlet channels 2112 face the left side of the chassis 1, as shown in Figure 6 shown, and the water outlets of the other two water outlet channels 2112 face the right side of the chassis 1, as shown in Figure 7 shown. The staff can choose to connect the quick-connect water pipe on the left or right side of the robot according to the actual situation, which is simple and convenient to operate.

[0060] In this embodiment, the drainage robot is generally a rear-wheel drive vehicle, with its drive wheels at the rear of the chassis 1 and the driven wheels at the front of the chassis 1. In this embodiment, the water outlet channel 2112 is detachably connected to the chassis 1 through a support assembly 13. The water outlet channel 2112 is relatively long, and the support assembly 13 plays a supporting role, hanging the water outlet channel 2112 inside the chassis 1 to ensure that the water outlet channel 2112 will not loosen or be damaged due to vibration or impact during the movement of the robot.

[0061] In this embodiment, the detachable connection can be achieved by bolts, snap fasteners or other types of fasteners, allowing users to disassemble when needed, which is convenient for cleaning, inspection or replacement.

[0062] In this embodiment, the support assembly 13 includes a support plate 131 and a U-bolt 132. The support plate 131 is connected to the cross beam 14 of the chassis 1 by bolts. There are two slots on the support plate 131 for the U-bolt 132 to pass through. The U-bolt 132 sleeved around the water outlet channel 2112 and passes through the slots, and is locked on the support plate 131 with a nut 133. The stable water outlet channel 2112 reduces safety accidents caused by pipeline loosening or breakage, ensuring the smooth progress of the drainage operation.

[0063] Different from the implementation manner of the support plate 131 and the U-bolt 139132, please refer to Figure 8 and Figure 9 , in another embodiment, the support assembly 13 includes a shock absorber, a first connecting plate 134 and a second connecting plate 135. The first connecting plate 134 is arranged on the water outlet channel, and the second connecting plate 135 is arranged on the subframe. The first connecting plate 134 is connected to the second connecting plate 135 through the shock absorber, and the first connecting plate 134 and the second connecting plate 135 are relatively arranged up and down. Most of the vibrations during the operation of the drainage robot will be absorbed by the shock pads, thereby reducing the amount of vibration transmitted to the chassis 1.

[0064] Please refer to Figure 8 and Figure 9 , further, the first connecting plate 134 is located above the second connecting plate 135, and the shock absorber has upper and lower shock pads. The shock pads are split type, and through the upper and lower shock pads, vibrations can be effectively absorbed.

[0065] Please refer to Figure 8 and Figure 9 , furthermore, the shock absorber includes a first shock pad 136, a second shock pad 137, a protective plate 138 and a bolt 139. The second connecting plate 135 is provided with an installation groove for accommodating the first shock pad 136. The first shock pad 136 is sleeved on the installation groove through the step on the outer wall. A support ring 130 is sleeved inside the inner ring of the first shock pad 136. The inner ring of the second shock pad 137 is sleeved on the part of the support ring 130 protruding out of the first shock pad 136. The second shock pad 137 is located below the first shock pad 136. A protective plate 138 is provided below the second shock pad 137 and the support ring. The bolt 139 forms a threaded connection with the first connecting plate 134, the inner ring of the support ring 130 and the protective plate 138. If the robot is pressed downward by force, it acts on the first shock pad 136, and the first shock pad 136 is stressed and absorbs shock. If the robot jumps upward due to vibration, the protective plate 138 acts on the second shock pad 137, and the second shock pad 137 is stressed and absorbs shock.

[0066] Figure 9 It is shown that the first shock absorber pad 136 is in an inverted "convex" shape. The lower end of the first shock absorber pad 136 is located in the mounting groove, and the second connecting plate 135 supports the stepped part at its middle. The part of the second connecting plate 135 where the mounting groove is provided can be thickened to increase the strength of the structure. The upper surface of the second shock absorber pad 137 can be attached to the lower surface of the second connecting plate 135, and the lower surface of the second shock absorber pad 137 can be attached to the protective plate 138. The protective plate 138 and the first connecting plate 134 press and limit the two shock absorber pads up and down, and the support ring 130 supports and limits within the inner circles of the two shock absorber pads.

[0067] Bolt 139 connection is a commonly used mechanical fastening method for fixing two or more parts together. It ensures the reliability and stability of the connection through the self-locking characteristic of the thread and the action of the pre-tightening force. Figure 9 It is shown that the head of the bolt 139 passes through the protective plate 138, the second shock absorber pad 137, the support ring 130, the first shock absorber pad 136, and the first connecting plate 134 from bottom to top, and is fastened with a nut 1391. At the same time, a washer can be provided to protect the nut and disperse the pressure.

[0068] It is worth mentioning that Figure 9 It is shown that the first connecting plate 134 and the second connecting plate 135 are L-shaped. The shock absorber is located between the horizontal parts that extend horizontally of the two. The horizontal parts of the two are close to each other. The vertical parts of the first connecting plate 134 and the second connecting plate 135 can be welded to the water channel 2112 and the cross beam of the subframe 12 respectively.

[0069] In some other embodiments, the shock absorber can be in the form of a spring, hydraulic or pneumatic, and is installed between the first connecting plate 134 and the second connecting plate 135 to absorb vibration.

[0070] Please refer to Figure 3 and Figure 5 In this embodiment, the chassis 1 includes two crawlers and a subframe 12 provided between the two crawlers. The fire pump 21 is provided on the subframe 12. Preferably, the upper surface of the chassis 1 is provided with a slot hole 11. The subframe 12 is provided below the slot hole 11 of the chassis 1. The fire pump 21 is located in the slot hole 11 and is provided on the subframe 12. The design of the slot hole 11 enables the fire pump 21 to be installed in an embedded manner, making the whole more compact, reducing the height, and facilitating entry into narrow environments. The subframe 12, as a support structure, ensures that the fire pump 21 is firmly installed on the chassis 1.

[0071] In this embodiment, the drainage robot further includes a water hose, which is detachably connected to the water outlet or water inlet of the fire pump 21. The water hose can be connected to the water outlet or water inlet of the fire pump 21 through a fire hose coupling, a Paul joint or other types of connectors. This detachable design enables the water hose to be conveniently connected and disconnected before and after use, which not only simplifies the operation process but also facilitates the maintenance and replacement of the water hose.

[0072] In this embodiment, the water hose is DN40, DN65, DN80, DN100, DN150, DN200, DN250, DN300 or DN400 to adapt to different flow requirements and working environments. Among them, DN is the nominal diameter, also known as the average outside diameter, which refers to the standardized diameter series of pipes and their accessories.

[0073] Please refer to Figure 2 , in this embodiment, the fire pump 21 includes a pump casing 211 and a gearbox 212. An impeller is provided inside the pump casing 211. The shaft of the impeller is connected to the output end of the gearbox 212, and the input end of the gearbox 212 is connected to the motor 22. The pump casing 211 has a water inlet channel 2111 and a water outlet channel 2112. The pump casing 211 is the main component of the fire pump 21, which houses the impeller shaft and the impeller inside. It generates power through rotation to suck water from the water inlet and discharge it from the water outlet. The impeller shaft of the fire pump 21 is driven by the output end of the gearbox 212. The gearbox 212 can adjust the rotational speed of the impeller shaft according to actual needs to adapt to different water supply or drainage requirements, especially increasing the rotational speed of the impeller shaft to better pressurize.

[0074] Please refer to Figure 2 , in this embodiment, the fire pump 21 further includes a vacuum pump 213. The pump casing 211 is provided with a connection port, and the connection port is connected to the vacuum pump 213 through a pipeline 2131. The vacuum pump 213 is used to provide negative pressure for the pump casing 211. The vacuum pump 213 is connected to the pump casing 211 through the connection port. When working, it can extract the air inside the pump casing 211 to create a low-pressure environment. Before starting the fire pump 21, first start the vacuum pump 213, and evacuate the air inside the pump casing 211 through the pipeline 2131 to form negative pressure. When the pressure inside the pump casing 211 is lower than the external water pressure, water will be sucked into the pump casing 211, and then the water will be pushed out through the rotation of the impeller to complete the water pumping process.

[0075] Please refer to Figure 2, in this embodiment, the rated outlet pressure of the fire pump 21 is greater than or equal to 0.8 Mpa (megapascal, pressure unit). The outlet pressure can be detected by a pressure sensor. The rated outlet pressure can be detected by a pressure sensor. When the fire pump 21 is in the rated power state and the outlet pressure is greater than or equal to 0.8 MPa, it can ensure that the fire pump 21 has a large lift and can perform remote water supply operations. When the fire pump 21 is in the rated state, its rated outlet pressure can be 0.8 MPa, 1.0 MPa, 1.5 MPa, 3.0 MPa, 3.5 MPa, 4.0 MPa, etc., depending on the actual requirements. Taking the rated outlet pressure of the fire pump 21 as 0.8 MPa as an example, when changing the speed or pressure of the fire pump 21 to make the fire pump 21 in a light load state and its water outlet pressure is less than 0.8 MPa, such a technical solution also belongs to the protection scope of this application.

[0076] In this embodiment, the driving mode of the fire pump 21 is hydraulic drive, the motor 22 is a hydraulic motor 22, and the power mechanism further includes a hydraulic station that provides hydraulic power for the hydraulic motor 22. The fire pump 21 obtains power through the hydraulic motor 22, and the power of the hydraulic motor 22 comes from an independent hydraulic station, which contains components such as a hydraulic oil pump, a fuel tank, a filter, and a valve group for generating and controlling hydraulic power. The hydraulic valve group can be integrated on the chassis 1 of the drainage robot, and the relatively large-sized hydraulic oil pump, fuel tank, and filter can be arranged outside the chassis 1 and located on the mother vehicle.

[0077] In another embodiment, the driving mode of the fire pump 21 is electric drive, the motor 22 is an electric motor 22, and the power mechanism further includes an engine and a generator. The engine is connected to the electric motor 22 through the generator, and the engine and the generator are arranged outside the chassis 1. When the engine runs, it drives the generator to generate electricity, and the generated electricity is supplied to the electric motor 22 to drive the fire pump 21. Since the engine and the generator are relatively large in size, they can be placed on the mother vehicle to save space for the drainage robot. The drainage robot can be made smaller in size and can adapt to low, short, and narrow working environments.

[0078] Please refer to Figure 1 , in this embodiment, the chassis 1 is a wheeled chassis 1 or a tracked chassis 1 (such as a hydraulically driven tracked chassis 1). Figure 1 The shown chassis 1 is a tracked chassis 1. The tracked chassis 1 has a large driving force (usually the driving force of each track can reach 35%-45% of the machine weight), a small ground contact pressure (40-150 kPa), so it has good cross-country performance and stability, a large climbing ability (generally 50%-80%, and the maximum can reach 100%), a small turning radius, and good flexibility. It has strong obstacle-crossing ability and terrain adaptability (it can cross stairs, roadblocks, etc.) and can turn in place. It is suitable for working in deep and complex environments, and thus can adapt to low, short, and narrow working environments and complex road conditions.

[0079] Please refer to Figure 10 , this embodiment also provides a mother-and-son type emergency rescue and drainage equipment, including an emergency rescue vehicle (mother vehicle) and a drainage robot (son vehicle). The drainage robot is the drainage robot described in any one of the above embodiments, and the structure is as Figures 1 to 5 shown. The emergency rescue vehicle is provided with a carriage for transporting the drainage robot.

[0080] The emergency rescue vehicle is usually a large vehicle with strong mobility and load capacity. Its carriage is designed to stably carry the drainage robot. When a disaster occurs, the emergency rescue vehicle can quickly reach the scene and unload the drainage robot to the specific location where drainage operations are required. In addition, a hydraulic station and / or an engine and / or a generator for the drainage robot can be provided on the emergency rescue vehicle.

[0081] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
