Description

Technical Field

[0001] This invention belongs to the field of urban flood control technology, and specifically relates to a vehicle used for urban flood control operations. Background Technology

[0002] Urban flooding is a prominent problem plaguing many large and medium-sized cities in my country. In recent years, extreme rainfall has become more frequent, causing rapid water accumulation in low-lying areas, underground parking garages, underpasses, culverts, and the ends of drainage ditches, seriously threatening people's lives and property and the normal operation of cities. Similarly, in agricultural irrigation and farmland drainage, overflowing ditches and waterlogging in low-lying fields also occur frequently, requiring efficient drainage methods. To address these various waterlogging problems, a variety of drainage and emergency response equipment has emerged, among which mobile drainage and flood control vehicles are the most widely used.

[0003] However, common urban flood control vehicles often have the following drawbacks:

[0004] First, the pumping devices of most existing work vehicles are fixed inside the vehicle compartment. When in use, the pump must be manually removed from the compartment and placed at the pumping location. This method is not only cumbersome and labor-intensive, but also poses safety risks when facing narrow passages, wall crevices, deep parking spaces, the ends of drainage ditches, and low, cramped spaces due to limited visibility, unknown water depth, and unknown hazards such as foreign objects. It is difficult to accurately deliver the pump to the deepest pumping point manually.

[0005] Second, existing equipment typically uses multiple independent engines to drive water pumps and various actuators, resulting in a complex system structure, high energy consumption, and the potential for mutual interference when multiple independent drive sources work together, affecting operational stability.

[0006] Third, the existing flood control vehicles usually have a fixed cargo box height and do not have an active lifting function. As a result, water can easily seep into the cargo box, causing damage to core components such as the engine and electrical control system inside the cargo box.

[0007] Fourth, the working angle and extension distance of the water pumps in the existing equipment are mostly fixed, making it difficult to adjust flexibly according to actual needs. This makes it impossible for the water pump suction port to effectively approach and fit the water point, resulting in a large gap between the suction port and the water surface, which reduces the overall drainage efficiency.

[0008] To address the aforementioned problems, this invention proposes a vehicle for urban flood control operations. Summary of the Invention

[0009] To address the problems existing in the background art, the present invention provides a vehicle for urban flood control operations.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A vehicle for urban flood control includes a lower body with tracked wheels rotatably mounted on both sides. A cargo box is connected to the top of the lower body via a lifting mechanism. A fixed frame is fixedly mounted inside the lower body, and a sliding plate is slidably mounted within the fixed frame, with a spring between the sliding plate and the fixed frame. A hinge seat is slidably mounted within the sliding plate, and a swing frame is rotatably mounted on the outer surface of the hinge seat. A driving component acting on the hinge seat is mounted on the fixed frame, and a linkage component acting on the swing frame is mounted on the sliding plate. A mounting frame is fixedly mounted on the swing frame, and a second hydraulic rod is fixedly mounted on the mounting frame. A movable frame is fixedly mounted on the telescopic shaft of the second hydraulic rod. A water pump is rotatably mounted on the movable frame, and a third hydraulic rod is located between the water pump and the movable frame.

[0012] Furthermore, the driving component includes a first hydraulic rod, the top of the sliding plate is provided with a sliding groove, and the hinge seat is slidably disposed in the sliding groove; the first hydraulic rod is fixedly installed on the top of the fixed frame, and the telescopic shaft of the first hydraulic rod is fixedly connected to the hinge seat.

[0013] Furthermore, the linkage component includes a rotating shaft that rotatably passes through a hinge seat, and the swing frame is fixedly connected to the rotating shaft; a swing rod is fixedly provided at the end of the rotating shaft, and an oblong groove is provided on the swing rod; a fixing rod is fixedly provided on the outer surface of the sliding plate, and the fixing rod is limited and slidably disposed in the oblong groove.

[0014] Furthermore, a water pipe is detachably and fixedly connected to the water pump, and a limiting wheel assembly acting on the water pipe is provided in the lower vehicle body; the limiting wheel assembly includes two first limiting wheels, which are rotatably mounted at the bottom of the mounting frame; a support plate is fixedly mounted on the lower vehicle body, and two second limiting wheels are rotatably mounted on the support plate, which are respectively located at both ends of the support plate; two sliding seats are slidably mounted in the middle of the support plate, and a fourth hydraulic rod is fixedly mounted between each sliding seat and the support plate; a tensioning wheel is rotatably mounted on the top of each sliding seat, and the two tensioning wheels are staggered.

[0015] Furthermore, the lower body is equipped with a track walking mechanism that acts on the track wheels, and the track walking mechanism is driven by a walking hydraulic motor; the lifting mechanism is driven by a lifting hydraulic cylinder; and the water pump is driven by a water pumping hydraulic motor.

[0016] Furthermore, the carriage is equipped with an equipment compartment, in which an engine and a hydraulic multi-path distribution system are fixedly installed. The output end of the engine is rigidly and coaxially connected to the main hydraulic pump of the hydraulic multi-path distribution system. The hydraulic multi-path distribution system includes multiple independent working branches, each equipped with an independent control valve. The traveling hydraulic motor, the water pumping hydraulic motor, the lifting hydraulic cylinder, the first hydraulic rod, the second hydraulic rod, the third hydraulic rod, and the fourth hydraulic rod are respectively connected to the corresponding working branches.

[0017] Furthermore, a control system is also installed inside the equipment compartment, and the control system is electrically connected to multiple control valves.

[0018] Furthermore, the equipment compartment is also equipped with an on-board battery pack, a hydraulic drive motor, and a generator. The output end of the hydraulic drive motor is connected to the input end of the generator, and the output end of the generator acts on the on-board battery pack and the working equipment installed on the surface of the vehicle body. The hydraulic drive motor is connected to the corresponding working branch of the hydraulic multi-path diversion system.

[0019] The present invention has the following beneficial effects:

[0020] 1. This application, through the coordinated design of the drive unit and linkage components, can automatically extend or retract the swing frame and water pump from the rear of the vehicle. During the extension process, the swing frame automatically rotates from a vertical to a horizontal position, eliminating the need for manual handling, thus improving operational convenience and reducing labor intensity. In areas difficult for personnel to access, such as narrow passages, wall crevices, deep parking spaces, the ends of drainage ditches, and low, confined areas with unknown hazards, operators can use the drive unit to propel the water pump, thereby improving operational safety.

[0021] 2. This application uses an engine as the sole power source, converting mechanical energy into high-pressure hydraulic energy through a hydraulic main pump. This hydraulic energy is then distributed to the travel hydraulic motor, water pumping hydraulic motor, lifting hydraulic cylinder, hydraulic drive motor, and various hydraulic rods via a hydraulic multi-path distribution system. Each branch is equipped with an independent control valve, enabling individual start / stop, speed adjustment, and pressure regulation. The various actions do not interfere with each other, allowing for both single-function and multi-function synchronous operation. The system is simple, energy-efficient, and highly reliable.

[0022] 3. This application has a lifting mechanism between the lower body and the carriage, which can lift the carriage in real time according to the water depth, so that the core components such as the engine and electrical system are away from the water surface, avoiding water from entering the carriage and causing damage, thus improving the safety of the equipment.

[0023] 4. This application allows the water pump to extend into the accumulated water at different distances via the second hydraulic rod, and the water pump's suction angle can be adjusted via the third hydraulic rod to ensure that the suction port is always horizontal and downward, effectively eliminating the gap between the suction port and the accumulated water and improving drainage efficiency.

[0024] 5. This application includes a remote control terminal installed in the driver's cab. Operators can send electrical signals via a joystick, allowing the control system to directly and remotely control the track movement, steering, starting, stopping, and speed adjustment, precisely guiding the vehicle to the designated drainage point. Simultaneously, the outer surface of the vehicle body is equipped with an IP68 waterproof-rated infrared night vision panoramic camera, capable of clearly capturing real-time images in dimly lit underground or deep-water immersion environments, assisting remote operation and reducing personnel safety risks associated with traditional operations.

[0025] 6. This application uses tracked wheels instead of traditional wheeled walking mechanisms, which can travel for a long time in deep water, muddy swamps, and soft fields, eliminating problems such as getting stuck, slipping and stalling. It is specially adapted to high-risk working environments in enclosed deep water such as basements and underground parking lots.

[0026] 7. This application is equipped with a hydraulic drive motor and a generator. The high-pressure hydraulic oil provided by the hydraulic multi-channel diversion system drives the generator rotor to rotate, converting hydraulic energy into electrical energy. This can power on-site emergency equipment and lighting equipment, and simultaneously charge the vehicle battery pack, ensuring that the battery has continuous power, maintaining the low-power standby and control capabilities of the control system, and improving the continuous operation capability of the equipment.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1-10 As shown, the technical solution adopted by this invention is as follows: A vehicle for urban flood control operations includes a lower body 2, with track wheels 1 rotatably mounted on both sides of the lower body 2. A tracked walking mechanism acting on the track wheels 1 is provided on the lower body 2, and the tracked walking mechanism is driven by a walking hydraulic motor. A carriage 3 is connected to the top of the lower body 2 via a lifting mechanism, which is driven by a lifting hydraulic cylinder. It should be noted that both the tracked walking mechanism and the lifting mechanism are conventional prior art and will not be described in detail here.

[0042] The lower body 2 is fixedly equipped with a fixed frame 4. A sliding plate 5 is slidably mounted within the fixed frame 4. A spring 6 is provided between the sliding plate 5 and the fixed frame 4, with one end of the spring 6 fixedly connected to the sliding plate 5 and the other end fixedly connected to the fixed frame 4. A hinge seat 8 is slidably mounted within the sliding plate 5. A swing frame 9 is rotatably mounted on the outer surface of the hinge seat 8. The fixed frame 4 is equipped with a driving component that acts on the hinge seat 8, and the sliding plate 5 is equipped with a linkage component that acts on the swing frame 9.

[0043] Specifically, the driving component includes a first hydraulic rod 14, a groove 7 is formed on the top of the sliding plate 5, and a hinge seat 8 is slidably disposed within the groove 7. The first hydraulic rod 14 is fixedly installed on the top of the fixed frame 4, and the telescopic shaft of the first hydraulic rod 14 is fixedly connected to the hinge seat 8.

[0044] Specifically, such as Figure 5 As shown, the linkage assembly includes a rotating shaft 10, which rotatably passes through a hinge seat 8, and a swing frame 9 is fixedly connected to the rotating shaft 10. A swing rod 11 is fixedly installed at the end of the rotating shaft 10, and a waist-shaped groove 12 is formed on the swing rod 11. A fixing rod 13 is fixedly installed on the outer surface of the sliding plate 5, and the fixing rod 13 is limited and slidably installed in the waist-shaped groove 12.

[0045] The swing frame 9 is fixedly mounted with a mounting frame 15, and a second hydraulic rod 16 is fixedly mounted on the mounting frame 15. A movable frame 17 is fixedly mounted on the telescopic shaft of the second hydraulic rod 16. A water pump 18 is rotatably mounted on the movable frame 17. A third hydraulic rod 21 is provided between the water pump 18 and the movable frame 17. One end of the third hydraulic rod 21 is rotatably connected to the water pump 18, and the other end is rotatably connected to the movable frame 17.

[0046] Furthermore, a level sensor 22 is fixedly installed on the top of the water pump 18, and the water pump 18 is driven by a pumping hydraulic motor.

[0047] The water pump 18 is detachably and fixedly connected to a water pipe 19, and the other end of the water pipe 19 is connected to an external drain pipe to discharge the accumulated water into a specific environment.

[0048] Furthermore, the swing frame 9 is provided with a clearance hole 20 for making way for the water pipe 19.

[0049] The lower body 2 is equipped with a limiting wheel assembly that acts on the water pipe 19.

[0050] Specifically, the limiting wheel assembly includes a first limiting wheel 25, with two first limiting wheels 25 rotatably mounted on the bottom of the mounting bracket 15. A support plate 30 is fixedly mounted on the lower body 2, and two second limiting wheels 26 are rotatably mounted on the support plate 30, located at opposite ends of the support plate 30. Two sliding seats 28 are slidably mounted in the middle of the support plate 30, with a fourth hydraulic rod 29 fixedly mounted between each sliding seat 28 and the support plate 30. A tensioning wheel 27 is rotatably mounted on the top of each sliding seat 28, and the two tensioning wheels 27 are staggered. The water pipe 19 sequentially passes around the corresponding first limiting wheel 25, second limiting wheel 26, and tensioning wheel 27 (see reference). Figure 1 ).

[0051] In addition, the rear of the carriage 3 is hinged to a door 23 via a hinge 24. The outer surface of the carriage 3 is equipped with multiple sets of panoramic waterproof cameras, which are installed at the front, rear and left and right sides of the carriage. All of them are IP68 waterproof and infrared night vision, so they can clearly capture real-time images even in dark underground or deep water immersion environments.

[0052] Carriage 3 contains an equipment compartment and a driver's compartment.

[0053] The equipment compartment contains an on-board battery pack, a hydraulic drive motor, and a generator. The output end of the hydraulic drive motor is connected to the input end of the generator, and the output end of the generator acts on the on-board battery pack and the working equipment installed on the surface of the compartment 3.

[0054] The equipment compartment houses a fixed engine and a hydraulic multi-path distribution system. The engine's output is rigidly and coaxially connected to the input of the hydraulic multi-path distribution system (i.e., the main hydraulic pump). The engine is the sole power source; upon startup, it directly drives the main hydraulic pump to operate synchronously, converting the engine's mechanical energy into high-pressure hydraulic energy. This high-pressure hydraulic energy powers the hydraulic multi-path distribution system, enabling precise power distribution for the precise driving of other components.

[0055] The hydraulic multi-path diversion system includes multiple independent pipelines. The high-pressure hydraulic energy generated by the hydraulic main pump can be precisely distributed to multiple independent pipelines, thereby forming multiple completely independent working branches. Each working branch is equipped with an independent control valve, so as to realize independent start-up and shutdown, independent speed adjustment, and independent pressure adjustment. Each branch does not interfere with or affect each other. It can operate with a single function or operate with multiple functions simultaneously.

[0056] The walking hydraulic motor, the water pumping hydraulic motor, the lifting hydraulic cylinder, the hydraulic drive motor, the first hydraulic rod 14, the second hydraulic rod 16, the third hydraulic rod 21, and the fourth hydraulic rod 29 are respectively connected to the corresponding pipes.

[0057] The equipment compartment is equipped with a PLC control system, which is independently powered by the vehicle's battery pack and can operate in low-power standby mode without starting the engine. The PLC control system is electrically connected to control valves in multiple pipelines. The operator in the cab sends control signals via a remote terminal joystick, which are transmitted to the PLC control system. The PLC control system can control the travel hydraulic motor, the water pumping hydraulic motor, the lifting hydraulic cylinder, the hydraulic drive motor, the first hydraulic rod 14, the second hydraulic rod 16, the third hydraulic rod 21, and the fourth hydraulic rod 29 to complete the corresponding functions.

[0058] The specific working branches formed by the hydraulic multi-path diversion system are as follows:

[0059] First branch (walking drive branch): The high-pressure hydraulic oil generated by the hydraulic main pump is delivered to the walking hydraulic motor through the first channel. The flow rate and direction of the hydraulic oil are adjusted by the independent control valve in the first channel, thereby controlling the speed and forward / reverse rotation of the walking motor, and thus realizing the walking, steering and speed adjustment of the track wheel 1.

[0060] The second branch (pumping drive branch): The high-pressure hydraulic oil generated by the main hydraulic pump is delivered to the pumping hydraulic motor through the second channel, providing high-pressure hydraulic oil to the pumping hydraulic motor, thereby driving the impeller of the water pump 18 to rotate at high speed to complete the pumping operation.

[0061] The third branch (lifting drive branch): High-pressure hydraulic oil generated by the main hydraulic pump is delivered to the lifting hydraulic cylinder through the third channel, providing hydraulic power for the extension and retraction of the lifting hydraulic cylinder, thereby realizing the lifting and lowering of the carriage 3. At the same time, the third channel is equipped with a high-pressure flexible hydraulic hose, the length of which is reserved for the lifting stroke, to meet the extension and bending between the highest and lowest positions of the carriage 3, ensuring continuous and uninterrupted power transmission.

[0062] The fourth branch (power generation drive branch): The high-pressure hydraulic oil generated by the hydraulic main pump is delivered to the hydraulic drive motor through the fourth channel. The hydraulic drive motor drives the generator rotor to rotate at high speed, thereby converting hydraulic energy into stable 220V AC power. On the one hand, it powers the on-site emergency equipment and lighting equipment, and on the other hand, it charges the vehicle battery pack to ensure that the vehicle battery pack has continuous power and maintains the operation of the PLC control system (on-site power supply, battery charging, ensuring the normal operation of all electrical systems).

[0063] In addition, the hydraulic multi-path diversion system also includes multiple branch channels, which are used to control the first hydraulic rod 14, the second hydraulic rod 16, the third hydraulic rod 21 and the fourth hydraulic rod 29 respectively, so as to realize their corresponding functions, which will not be described in detail.

[0064] It should be noted that the PLC control system, engine, hydraulic multi-path diversion system, vehicle battery pack, generator, and the pipes and control valves corresponding to the multiple branches in this application are all conventional prior art, and will not be described in detail here.

[0065] Working principle: In the initial state, such as Figure 1 and Figure 8 As shown, the first hydraulic rod 14 is in a retracted state, the spring 6 is in a compressed state, the swing frame 9 is in a vertical position, the water pump 18, the second hydraulic rod 16 and the water pipe 19 are all stored in the rear of the carriage 3, and the door 23 is closed to avoid the working parts being exposed when not in operation, thereby reducing the risk of collision and dust pollution.

[0066] When flood control and drainage operations are required, the vehicle is driven into the drainage operation area. Depending on the actual water depth, the operator can control the lifting mechanism to raise the vehicle compartment 3 upwards, preventing water from entering the interior of the vehicle compartment 3 and ensuring the safety of the engine and electrical system.

[0067] Before lifting the carriage 3, first open the door 23, then extend the telescopic shaft of the first hydraulic rod 14. At this time, the compressed spring 6 gradually recovers its deformation, pushing the sliding plate 5 to slide outwards towards the fixed frame 4, while the swing frame 9 remains vertical and extends along with the sliding plate 5. When the spring 6 has fully returned to its natural state, the water pump 18, the second hydraulic rod 16, and the water pipe 19 are just fully extended to the outside of the rear of the carriage 3, at which point the carriage 3 can be safely lifted.

[0068] Subsequently, the telescopic shaft of the first hydraulic rod 14 continues to extend. Since the spring 6 has returned to its natural state and exerts a certain pulling force on the sliding plate 5, the sliding plate 5 cannot move outward for the time being. The extension force of the first hydraulic rod 14 pushes the hinge seat 8 to continue sliding outward along the slide groove 7. The hinge seat 8 drives the swing frame 9 and the swing rod 11 to move together. Under the cooperation of the fixed rod 13 and the waist-shaped groove 12, the swing rod 11 is pushed by the fixed rod 13 and rotates around the rotating shaft 10, thereby driving the swing frame 9 to rotate synchronously through the rotating shaft 10.

[0069] When the swing frame 9 rotates approximately 90 degrees, it is in a horizontal position, and the suction port of the water pump 18 is vertically downward. At this time, by extending the telescopic shaft of the second hydraulic rod 16, the water pump 18 can be pushed out of the swing frame 9 and downward into the water accumulation. After connecting the water pipe 19 to the external drain pipe, the water pump 18 can be turned on to carry out the drainage operation.

[0070] During water intake, the horizontal sensor 22 monitors the vertical attitude of the water pump 18 in real time. If tilting is detected, the control system can automatically control the extension and retraction of the third hydraulic rod 21 based on the monitoring data to dynamically adjust the angle of the water pump 18, ensuring that the water inlet always maintains a horizontal and downward-facing efficient water intake posture. The operator can also manually adjust the angle of the water pump 18 from the cab via a remote control terminal according to the on-site water level and terrain conditions. Manual control has priority to further improve the thoroughness and maneuverability of drainage.

[0071] During the extension and angle adjustment of the water pump 18, the water pipe 19 will bend and deform as the water pump 18 moves. Since the water pipe 19 passes through the first limiting wheel 25, the second limiting wheel 26 and the tensioning wheel 27 in sequence, and under the drive of the fourth hydraulic rod 29, the sliding seat 28 can drive the tensioning wheel 27 to move, thereby automatically adjusting the folding length of the water pipe 19 to adapt to the real-time distance between the water pump 18 and the fixed end of the water pipe 19, ensuring smooth water delivery.

[0072] If the tracked vehicle encounters narrow passages, wall crevices, or the end of drainage ditches where it cannot pass, and the water accumulation point is far from the carriage 3, the extension shaft of the first hydraulic rod 14 can be continued to extend. At this time, since the bottom of the waist-shaped groove 12 has already abutted against the fixed rod 13, continuing to push the hinge seat 8 will not cause the swing frame 9 to continue rotating, but will instead pull the sliding plate 5 further outward through the waist-shaped groove 12 (see reference). Figure 10 This stretches the spring 6, thereby pushing the water pump 18 further away to achieve drainage without dead zones.

[0073] After the drainage operation is completed, the telescopic shaft of the second hydraulic rod 16 is first retracted to pull the water pump 18 and water pipe 19 upwards. Then, the telescopic shaft of the first hydraulic rod 14 is retracted, and the spring 6 gradually recovers its deformation as the first hydraulic rod 14 retracts. When the spring 6 has fully recovered its natural state, the first hydraulic rod 14 continues to retract, and the sliding plate 5 cannot move inwards under the thrust of the spring 6. The contraction force of the first hydraulic rod 14 pulls the hinge seat 8 to slide inwards along the slide groove 7. The hinge seat 8 drives the swing frame 9 and the swing rod 11 to move. Under the cooperation of the fixed rod 13 and the waist-shaped groove 12, the swing rod 11 drives the swing frame 9 to rotate 90 degrees in the opposite direction, returning it to a vertical state.

[0074] As the first hydraulic rod 14 continues to retract, the bottom of the waist-shaped groove 12 pulls the sliding plate 5 into the fixed frame 4 through the fixed rod 13, compressing the spring 6 again. At the same time, the water pump 18, water pipe 19 and the second hydraulic rod 16 are completely retracted into the rear of the carriage 3, and the door 23 is closed.

[0075] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
