[0041] Please refer to Figures 1 to 7 The present embodiment provides a drainage robot, comprising a chassis 1 with a walking mechanism, a fire fighting device 2 and a shock absorber 4, the fire fighting device 2 comprising a fire pump 21 and a power mechanism, the fire pump 21 being arranged on the chassis 1, the power mechanism comprising a motor 22, the motor 22 being arranged on the chassis 1 and in driving connection with the fire pump 21, and the shock absorber 4 being arranged between the fire pump 21 and the chassis 1.

[0042] The drainage robot is specially designed for performing drainage tasks in various complex terrains, such as urban waterlogging, mine waterlogging, tunnel waterlogging, and other environments, and can quickly drain water in water disasters or emergency situations while being mobile and remotely operated. The fire pump 21 can provide greater lift to pressurize and deliver water to a farther and higher place, and the remote water supply capability avoids the need to deploy additional pressurization devices in complex environments. The shock absorber 4 can reduce the vibration of the fire pump 21 during operation and the impact of bumps during the travel of the drainage robot on the fire pump 21, helping to maintain the stability of the fire pump 21.

[0043] Referring to Figure 2 and Figure 3 In this embodiment, the fire pump 21 is provided with a connecting plate 213, and the shock absorber 4 includes a shock-absorbing pad. The connecting plate 213, the shock-absorbing pad, and the chassis 1 are connected by bolts. When the fire pump 21 starts to work, it will generate a certain amount of vibration. Since the shock-absorbing pad is provided between the fire pump 21 and the chassis 1, most of the vibration will be absorbed by the shock-absorbing pad, thereby reducing the amount of vibration transmitted to the chassis 1. In some embodiments, the shock absorber 4 can be in the form of a spring, hydraulic or pneumatic, which is installed at the contact point between the fire pump 21 and the chassis 1 to absorb vibration.

[0044] In this embodiment, bolt 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 property of the thread and the effect of the pre-tightening force. Moreover, the bolt connection method facilitates the installation and removal of the fire pump 21. Bolt connection can be divided into two basic types: connection of bolt and screw hole, and connection of bolt and nut. Alternatively, as shown in Figure 4 The connecting plate 213, the shock-absorbing pad, and the chassis 1 are provided with holes for the use of the bolts 45, the bolts 45 pass through the through holes on the connecting plate 213 and the shock-absorbing pad, and are fastened in the screw holes 121 of the chassis 1 (such as the subframe 12 below). Alternatively, the bolts pass through the through holes on the connecting plate 213, the shock-absorbing pad, and the chassis 1, and are locked with nuts.

[0045] In this embodiment, the shock-absorbing pad is made of a material with high elasticity and good durability, such as rubber or polyurethane, for absorbing and reducing vibration energy. Preferably, the shock-absorbing pad is a rubber shock-absorbing pad, which has good elasticity and durability.

[0046] Referring to Figure 3 and Figure 4In this embodiment, the shock pad includes a first shock pad 41 and a second shock pad 42, and the shock absorber 4 further includes a first protective plate 43 and a second protective plate 44. The first protective plate 43 is located above the first shock pad 41, the first shock pad 41 is located above the connecting plate 213, the connecting plate 213 is located above the second shock pad 42, the second shock pad 42 is located above the second protective plate 44, and the second protective plate 44 is located above the chassis 1. The first protective plate 43, the first shock pad 41, the connecting plate 213, the second shock pad 42, the second protective plate 44, and the chassis 1 are connected by bolts. The first protective plate 43, the first shock pad 41, the second shock pad 42, and the second protective plate 44 are arranged in order from top to bottom, and the connecting plate 213 extends into the first shock pad 41 and the second shock pad 42. By using two layers of shock pads, the vibrations generated by the fire pump 21 during operation can be more effectively absorbed, significantly reducing the impact of vibrations on the overall robot structure and improving the stability of the robot. In some embodiments, only one layer of shock pad can be used, or more than two layers of shock pad can be used.

[0047] Please refer to Figure 2 and Figure 4 Preferably, the connecting plate 213 is generally L-shaped, with a vertical end fastened to the fire pump 21 by bolts and a horizontal end fastened to the chassis 1 by bolts.

[0048] Please refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the fire pump 21 includes a pump housing 211 and a gearbox 212. The pump housing 211 has an impeller inside, the shaft of the impeller is connected to the output end of the gearbox 212, the input end of the gearbox 212 is connected to the motor 22, and the pump housing 211 and / or the gearbox 212 is provided with a connecting plate 213. One or both of the pump housing 211 and the gearbox 212 is provided with a connecting plate 213, Figure 2 Both the pump housing 211 and the gearbox 212 are provided with a connecting plate 213. If the pump housing 211 is provided with a connecting plate 213, the pump housing 211 is connected to the chassis 1 through the connecting plate 213 and the shock absorber 4. If the gearbox 212 is provided with a connecting plate 213, the pump housing 211 is connected to the chassis 1 through the connecting plate 213 and the shock absorber 4, and the structure of the shock absorber 4 is described in detail above.

[0049] The pump housing 211 is the main component of the fire pump 21, which contains the impeller shaft and the impeller inside. Through rotation, it generates power 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, and the gearbox 212 can adjust the speed of the impeller shaft according to actual needs to adapt to different water supply or drainage needs, especially to increase the speed of the impeller shaft to better pressurize.

[0050] Please refer toFigure 2 Preferably, the pump housing 211 and / or the gearbox 212 are detachably connected with the connecting plate 213, which can be achieved by bolts, buckles or other means. Figure 2 The L-shaped connecting plate 213 is fixed between the pump housing 211 and the gearbox 212 by bolts.

[0051] Please refer to Figure 1 , Figure 3 and Figure 6 In this embodiment, the chassis 1 includes two tracks and a subframe 12 arranged between the two tracks, and the fire pump 21 is arranged on the subframe 12. Preferably, the upper surface of the chassis 1 is provided with a slot hole 11, and the chassis 1 is provided with a subframe 12 below the slot hole 11, and the fire pump 21 is located in the slot hole 11 and connected with the subframe 12 through the shock absorber 4. 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 access to narrow environments. The subframe 12 serves as a support structure to ensure that the fire pump 21 is stably installed on the chassis 1.

[0052] Please refer to Figure 1 and Figure 7 In this embodiment, the drainage robot also includes a winch 3 arranged on the chassis 1 for winding the water hose. The winch 3 includes a bracket 31 and a winding drum 32, the bracket 31 is arranged on the chassis 1, the winding drum 32 is arranged on the bracket 31, the winding drum 32 can rotate relative to the bracket 31, and the winding drum 32 can wind the water hose.

[0053] The bracket 31 is the basic structure of the winch 3, its main role is to support and fix the winding drum 32, to ensure the stability of the winch 3 during use. The bracket 31 needs to be firmly connected with the robot chassis 1, usually by bolts or welding, to ensure that the winch 3 does not loosen or fall off when the robot moves, and the winding drum 32 needs to be able to rotate relative to the bracket 31, which is usually achieved through bearings, and the winding drum 32 is driven to rotate relative to the bracket 31 by manual or electric means. In use, the winch 3 is operated to release the water hose, and after the water hose is unfolded, its port is connected to the water outlet or water inlet of the fire pump 21, and when it is stored, the water hose can be wound on the winch 3, which is convenient for storage, and orderly water hose management reduces a series of hazards caused by random water hose placement, and in emergency situations, it can quickly respond, speed up the drainage speed, improve the rescue efficiency, and improve the efficiency and convenience of the drainage operation.

[0054] When designing the drainage robot, considering that it needs to move in various complex environments, including narrow tunnels or pipes, the size and layout of the robot become the key consideration in the design. In this embodiment, the winch 3 is located on the left or right side of the motor 22, the size of the fire pump 21 is relatively large, and the motor 22 is relatively small. The winch 3 is ingeniously designed on the left or right side of the motor 22, avoiding the waste of internal space of the robot, making the whole device more compact.

[0055] Please refer to Figure 7 Further, the winch 3 is provided in two, and the two winches 3 are arranged side by side and located on the left and right sides of the motor 22, which can effectively utilize the larger space left around the motor 22. This layout not only maximizes the functionality of the robot, but also enables the robot to handle two water hoses simultaneously due to the double winch 3 configuration.

[0056] In this embodiment, the water hose is detachably connected to the water outlet or water inlet of the fire pump 21, and the water hose can be connected to the water outlet or water inlet of the fire pump 21 through a fire connector, a Paul connector or other types of connectors. This detachable design allows the water hose to be easily 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.

[0057] In this embodiment, the water hose is DN40, DN65, DN80, DN100, DN150, DN200, DN250, DN300 or DN400 to adapt to different flow requirements and operating environments. Among them, DN is the nominal diameter, also known as the average outer diameter, which refers to the standardized diameter series of pipes and their accessories.

[0058] In this embodiment, the driving mode of the fire pump 21 is hydraulic drive, and the motor 22 is a hydraulic motor 22. The power mechanism further includes a hydraulic station for providing hydraulic power to the hydraulic motor 22. The hydraulic station contains components such as hydraulic oil pumps, oil tanks, filters, valve groups, etc. for generating and controlling hydraulic power. The hydraulic valve group can be integrated on the chassis 1 of the water drainage robot, and the larger hydraulic oil pump, oil tank and filter can be placed outside the chassis 1 on the mother vehicle.

[0059] In another embodiment, the driving mode of the fire pump 21 is electric drive, and the motor 22 is an electric motor 22. The power mechanism further includes an engine and a generator, which cooperate to provide electric energy to the electric motor 22. The engine is connected to the electric motor 22 through the generator, and the engine and generator are placed outside the chassis 1. When the engine is running, the generator generates electricity, which is supplied to the electric motor 22 to drive the fire pump 21. Since the engine and generator are relatively large in size, they can be installed on the mother vehicle, saving space for the water drainage robot, which can be made smaller to adapt to low, narrow and narrow operating environments.

[0060] Please refer to Figure 1 In this embodiment, the chassis 1 is a wheeled chassis 1 or a tracked chassis 1 (such as a hydraulic drive tracked chassis 1), i.e. the walking mechanism is wheeled or tracked. Figure 1The chassis 1 shown is a tracked chassis 1, which has large driving force (generally, the driving force of each track can reach 35%-45% of the weight of the machine), small specific pressure (40-150 kPa), thus good off-road performance and stability, large climbing ability (generally 50%-80%, and the maximum can reach 100%), small turning radius, good flexibility, strong obstacle crossing ability and terrain adaptability (including stairs, roadblocks, etc. can be crossed), and can turn on the spot. It is suitable for working in complex environments, thus being able to adapt to low, narrow and complex working environments and complex road conditions.

[0061] The embodiment also provides a sub-mother type rescue device, which comprises a rescue vehicle (mother vehicle) and a drainage robot (daughter vehicle), the drainage robot is the drainage robot described in any one of the above embodiments, the rescue vehicle is provided with a vehicle compartment for transporting the drainage robot, and the structure of the drainage robot is as shown in Figures 1 to 7 .

[0062] The rescue vehicle is generally a large vehicle, which has strong mobility and load capacity, and the vehicle compartment is designed to stably carry the drainage robot. When a disaster occurs, the rescue vehicle can quickly reach the scene and unload the drainage robot to a specific position where drainage operation is needed. In addition, the rescue vehicle can be provided with a hydraulic station and / or an engine and / or a generator matched with the drainage robot.

[0063] It should be noted that although the above embodiments have been described in the present text, the patent protection scope of the present application is not limited thereby. Therefore, based on the innovative concept of the present application, the changes and modifications of the embodiments in the present text, or the equivalent structure or equivalent process conversion made by using the content of the present application specification and drawings, directly or indirectly apply the above technical solutions to other related technical fields, are all included in the protection scope of the present application patent.
