[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Please refer to Figures 1-6 A low water level pumping mechanism of a drainage vehicle, comprising a chassis 1 and a vehicle body 2 arranged on the chassis 1, a power supply system 22 arranged in the vehicle body 2, vehicle traveling tracks 3 arranged on both sides of the chassis 1, a space arranged between the bottom of the chassis 1 and the ground, a straightly lifting drainage pump 4 arranged in the space, a water inlet elbow 5 with a downward pipe opening connected to the water inlet of the drainage pump 4, and a water pump lifter 11 connected to the power supply system 22 and driving the drainage pump 4 to lift. When pumping, the drainage pump 4 is lowered to make the pipe opening of the water inlet elbow 5 close to the ground. In the utility model, the drainage pump 4 adopts the water inlet elbow 5 with the downward pipe opening. Since the pipe opening of the water inlet elbow 5 can be close to the ground when pumping, it can meet the pumping and drainage requirements of a lower water level. In addition, the drainage pump 4 can be flexibly adjusted in height according to actual requirements, improving the flexibility of the drainage operation and the passability of the vehicle body 2. The power supply system 22 is powered by the engine 8 and is provided with a battery for energy storage to meet the power supply requirements of the device and improve the endurance.

[0026] Further, an oil tank 6 and a hydraulic pump 7 connected to the oil tank 6 are arranged in the vehicle body 2. The hydraulic pump 7 is connected to the engine 8 and the hydraulic control system 9 and is connected to the hydraulic motor 10 driving the vehicle traveling tracks 3 through the hydraulic control system 9. The drainage pump 4 is connected to the hydraulic control system 9. The vehicle body 2 adopts a track type design, so that the vehicle can easily cope with complex and variable terrain conditions.

[0027] Further, the pipe opening of the water inlet elbow 5 is provided with uniformly distributed filter holes 12. Specifically, the filter holes 12 mainly intercept particles and impurities in water to protect the blades of the drainage pump 4 and prolong the service life of the drainage pump 4.

[0028] Further, the side of the pipe opening of the water inlet elbow 5 is provided with a side water inlet 13. The design of the side water inlet 13 can further close the pipe opening of the water inlet elbow 5 to the ground, and water can also be introduced through the side water inlet 13, further enhancing the pumping capacity.

[0029] Further, the tail of the vehicle body 2 is provided with a water hose storage bin 14, the water hose storage bin 14 is provided with a water hose reel 15 and a water hose winding motor 16 for driving the water hose reel 15 to rotate. In the utility model, the water hose reel 15 and the water hose winding motor 16 are adopted, the water hose winding motor 16 drives the water hose reel 15 to release the water hose before the drainage operation, and drives the water hose reel 15 to wind the water hose back after the operation is completed, so that the operation is convenient, and the working strength of the operator is reduced.

[0030] Further, one end of the chassis 1 is provided with a steel cable capstan 17 and a capstan motor 18 for driving the steel cable capstan 17 to rotate. Specifically, when performing drainage operation in some special terrain, such as mountain valley, lake drainage, etc., the drainage vehicle needs to gradually move down with the water level, and it is difficult to return after the operation is completed. Therefore, before the drainage operation in the special terrain, the steel cable on the steel cable capstan 17 needs to be pulled out and fixed to a reliable fixed stake such as a stone column or a tree trunk, and after the operation is completed, the steel cable traction vehicle body 2 is wound through the capstan motor 18 and cooperates with the hydraulic motor 10 to drive the caterpillar belt to pull the drainage vehicle back.

[0031] Further, the outside of the vehicle body 2 is provided with a hydraulic power output interface 19 connected with the hydraulic control system 9. The hydraulic power output interface 19 allows the drainage vehicle to be connected with external hydraulic equipment. For example, when a larger drainage capacity or a specific drainage operation is required, additional drainage pumps 4 or other hydraulic driven equipment can be connected through the hydraulic power output interface 19, so as to expand the function and performance of the drainage vehicle. Different operation environments may require different hydraulic equipment or tools, and the hydraulic power output interface 19 enables the drainage vehicle to flexibly adapt to various operation requirements, and only the corresponding hydraulic equipment needs to be replaced or connected.

[0032] Further, the top of the vehicle body 2 is fixed with a cargo rack 20 and a tool storage box 21. The top of the vehicle body 2 is fixed with the cargo rack 20 and the tool storage box 21, which further enhances the storage and carrying capacity of the drainage vehicle, optimizes the operation process, and improves the safety and convenience. These features enable the drainage vehicle to better meet various complex and variable operation requirements, and improve the overall performance and practicality.
