Description

Technical Field

[0001] The invention relates to the technical field of emergency rescue equipment, in particular to a low water level pumping mechanism of a drainage vehicle. Background Art

[0002] As a professional drainage rescue equipment, drainage vehicles are widely used in drainage, flood control, drainage, drought resistance and other fields. Traditional drainage vehicles often have problems such as low drainage efficiency and poor terrain adaptability, especially when operating in complex and changeable environments. These problems are particularly prominent. In order to solve the above problems, China's invention patent CN218929306U provides an emergency drainage rescue vehicle, which uses a self-propelled drainage robot. While achieving large-flow drainage operations, it also has the characteristics of high flexibility and strong passability.

[0003] As a powerful tool for dealing with urban waterlogging, large-displacement drainage trucks have won wide recognition in the market for their excellent safety and strong drainage capacity. However, for some low-lying roads, tunnels and other areas in the city where large areas of shallow water accumulate due to heavy rains, general pumps cannot pump water at low water levels. Therefore, it is difficult to use general pumps to quickly pump water and drain water in such areas during daily flood prevention and drainage rescue work. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] A low-water-level pumping mechanism of a drainage vehicle comprises a chassis and a vehicle body arranged on the chassis, a power supply system is arranged in the vehicle body, driving tracks are arranged on both sides of the chassis, an escape space is arranged between the bottom of the chassis and the ground, and a drainage pump with a linear lift is arranged in the escape space, a water inlet elbow with a downward-facing pipe opening is connected to the water inlet of the drainage pump, and a water pump lifter connected to the power supply system and driving the drainage pump to rise and fall is also arranged in the vehicle body, when pumping water, the drainage pump descends to make the pipe opening of the water inlet elbow close to the ground.

[0006] Furthermore, an oil tank and a hydraulic pump connected to the oil tank are provided in the vehicle body, the hydraulic pump is connected to the engine, the hydraulic control system and is connected to a hydraulic motor driving the vehicle tracks through the hydraulic control system, and the drainage pump is connected to the hydraulic control system.

[0007] Furthermore, evenly distributed filtering holes are provided at the pipe opening of the water inlet elbow.

[0008] Furthermore, a side water inlet is provided on the side of the pipe opening of the water inlet elbow.

[0009] Furthermore, a water hose storage compartment is provided at the rear of the vehicle body, and a water hose reel and a water hose winding motor for driving the water hose reel to rotate are provided in the water hose storage compartment.

[0011] Furthermore, a cargo rack and a tool storage box are fixed on the top of the vehicle body.

[0012] Furthermore, a hydraulic power output interface connected to the hydraulic control system is provided on the outside of the vehicle body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The drainage pump in the present invention adopts an inlet elbow with the pipe mouth facing downward. Since the pipe mouth of the inlet elbow can be close to the ground when pumping water, it can meet the pumping and drainage needs of lower water levels. In addition, the drainage pump can be lifted linearly, and the height of the drainage pump can be flexibly adjusted according to actual needs, thereby improving the flexibility of drainage operations and the passability of the vehicle body.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 6 A low-water level pumping mechanism of a drainage vehicle comprises a chassis 1 and a vehicle body 2 arranged on the chassis 1, a power supply system 22 is arranged in the vehicle body 2, driving tracks 3 are arranged on both sides of the chassis 1, an escape space is arranged between the bottom of the chassis 1 and the ground, and a linearly lifting drainage pump 4 is arranged in the escape space, a water inlet bend pipe 5 with a pipe mouth facing downward is 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 rise and fall is also arranged in the vehicle body 2, when pumping water, the drainage pump 4 descends to make the pipe mouth of the water inlet bend pipe 5 close to the ground. In the present invention, the drainage pump 4 adopts the water inlet bend pipe 5 with a pipe mouth facing downward, because the pipe mouth of the water inlet bend pipe 5 can be close to the ground when pumping water, so that it can meet the pumping and drainage needs of lower water levels; in addition, through the linearly lifting drainage pump 4, the height of the drainage pump 4 can be flexibly adjusted according to actual needs, thereby improving the flexibility of drainage operations and the passability of the vehicle body 2. The power supply system 22 is powered by the engine 8 to generate electricity and is provided with a battery for energy storage to meet the power supply requirements of the device and improve endurance.

[0026] Furthermore, the vehicle body 2 is provided with an oil tank 6 and a hydraulic pump 7 connected to the oil tank 6, the hydraulic pump 7 is connected to an engine 8, a hydraulic control system 9, and a hydraulic motor 10 driving the driving track 3 through the hydraulic control system 9, and the drainage pump 4 is connected to the hydraulic control system 9. The vehicle body 2 adopts a crawler design, so that the vehicle can easily cope with complex and changeable terrain conditions.

[0027] Furthermore, evenly distributed filter holes 12 are provided at the pipe opening of the water inlet elbow 5. Specifically, the filter holes 12 mainly intercept particles and debris in the water to protect the blades of the drainage pump 4 and extend the service life of the drainage pump 4.

[0028] Furthermore, a side water inlet 13 is provided on the side of the pipe opening of the water inlet elbow 5. The design of the side water inlet 13 allows water to enter through the side water inlet 13 when the pipe opening of the water inlet elbow 5 is closer to the ground, thereby further enhancing the pumping capacity.

[0029] Furthermore, a hose storage compartment 14 is provided at the rear of the vehicle body 2, and a hose reel 15 and a hose winding motor 16 for driving the hose reel 15 to rotate are provided in the hose storage compartment 14. The hose reel 15 and the hose winding motor 16 are used in the present invention, and the hose winding motor 16 drives the hose reel 15 to release the hose before the drainage operation is performed, and drives the hose reel 15 to rewind the hose after the operation is completed, which is convenient to operate and reduces the work intensity of the operator.

[0030] Furthermore, a steel cable winch 17 and a winch motor 18 for driving the steel cable winch 17 to rotate are installed at one end of the chassis 1. Specifically, when performing drainage operations in some special terrains, such as drainage of gullies and lakes, the drainage vehicle needs to gradually move down as the water level drops, and it will be difficult to return after the operation is completed. Therefore, before the drainage operation in special terrains, the steel cable on the steel cable winch 17 needs to be pulled out and fixed to a reliable fixed pile such as a stone pillar or a tree trunk. After the operation is completed, the winch motor 18 reels in the steel cable to pull the vehicle body 2 and cooperates with the hydraulic motor 10 to drive the crawler to pull the drainage vehicle back.

[0031] Furthermore, a hydraulic power output interface 19 connected to the hydraulic control system 9 is provided on the outside of the vehicle body 2. The hydraulic power output interface 19 allows the drainage vehicle to be connected to external hydraulic equipment. For example, when a larger drainage volume or a specific drainage operation is required, an additional drainage pump 4 or other hydraulically driven equipment can be connected through the hydraulic power output interface 19, thereby expanding the function and performance of the drainage vehicle. Different operating environments may require different hydraulic equipment or tools. The hydraulic power output interface 19 enables the drainage vehicle to flexibly adapt to various operating requirements, and only the corresponding hydraulic equipment needs to be replaced or connected.

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

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
