Description

TECHNICAL FIELD

[0002] As a professional drainage emergency equipment, the drainage vehicle is widely used in drainage, flood control, drainage, drought resistance and other fields. The traditional drainage vehicle often has problems such as low drainage efficiency and poor terrain adaptability, especially when working in complex and changeable environment. To solve the above problems, Chinese utility model patent CN218929306U provides an emergency drainage emergency vehicle, which adopts a self-propelled drainage robot, which can realize large-flow drainage operation, and has the characteristics of high flexibility and strong passability.

[0003] As a rescue tool for urban waterlogging, the large displacement drainage vehicle has won wide recognition in the market due to its excellent safety and powerful drainage capacity. However, the existing large displacement hydraulic drainage vehicle has limitations in continuous long-time operation, which is mainly due to the insufficient heat dissipation performance of the hydraulic system. Specifically, such drainage vehicles are usually used as mobile emergency equipment during the summer flood season, facing the challenges of high-temperature operating environment and lack of reliable circulating water sources. In addition, the hydraulic system of the large displacement hydraulic drainage vehicle has very high heat dissipation power, and the traditional air-cooled cooling method is not effective in maintaining the appropriate working temperature of the hydraulic system under long-time operation. Therefore, the system often has to be stopped for cooling due to overheating, and the emergency drainage operation itself has the characteristics of continuity and long-term nature, so frequent shutdown for cooling will undoubtedly seriously weaken the timeliness and reliability of the drainage emergency.

[0025] The vehicle body 2 is provided with a cooling device 11 and a heat dissipation fan 12 for heat dissipation of the cooling device 11, the cooling device 11 is provided with a circulating oil circuit 13 and a circulating water circuit 14, the circulating oil circuit 13 is connected with the hydraulic control system 8, and the vehicle body 2 is further provided with a water storage tank 15 and a water cooling pump 16 connected with the circulating water circuit 14. Specifically, in order to ensure the air inlet and outlet volume, the cooling device 11 and the heat dissipation fan 12 are suspended by a support and the like, and a grid is arranged on the side surface of the vehicle body 2 for air inlet and outlet to achieve the purpose of heat dissipation. In addition, the vehicle body 2 should be provided with a storage battery connected with various electrical appliances or an electric power system generated by the engine 7. The technical scheme of the utility model has the following advantages:

[0026] Improve the drainage efficiency: through the design of the straightly lifting drainage pump 4, the drainage position can be flexibly adjusted according to the actual demand, and the flexibility of the drainage operation and the passability of the vehicle body 2 are improved.

[0027] Enhance the terrain adaptability: the crawler type design makes the vehicle easily cope with complex and variable terrain conditions.

[0028] Optimize the heat dissipation performance: the mixed cooling device 11 of air cooling and water cooling effectively improves the hydraulic oil cooling effect of the vehicle, and ensures the stability and reliability under long time operation.

[0029] Further, the tail of the vehicle body 2 is provided with a water hose storage bin 17, and the water hose storage bin 17 is provided with a water hose reel 18 and a water hose winding motor 19 for driving the water hose reel 18 to rotate. In the utility model, the water hose reel 18 and the water hose winding motor 19 are adopted, the water hose winding motor 19 drives the water hose reel 18 to release the water hose before the drainage operation, and drives the water hose reel 18 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, the water tank inlet pump 20 is arranged in the vehicle body 2, and the filter pipe (not marked in the figure) connected with the water tank inlet pump 20 is fixed to the bottom of the shell of the drainage pump 4.

[0031] Further, the steel cable winch 21 and the winch motor 22 for driving the steel cable winch 21 to rotate are installed at one end of the chassis 1. Specifically, when the drainage operation is performed on some special terrain, such as the drainage of gullies and lakes, the drainage vehicle needs to gradually move downward along with the water level, and it will be difficult to return after the operation is completed. Therefore, before the drainage operation is performed on the special terrain, the steel cable on the steel cable winch 21 needs to be pulled out and fixed to reliable fixed piles such as stone columns and tree trunks, and after the operation is completed, the steel cable is wound through the winch motor 22 to pull the vehicle body 2 and drive the caterpillar through the hydraulic motor 9 to pull the drainage vehicle back.

Different operation environments may require different hydraulic equipment or tools. The hydraulic power output interface 23 enables the drainage vehicle to flexibly adapt to various operation requirements, and only the corresponding hydraulic equipment needs to be replaced or connected.

[0033] Further, the cargo rack 24 and the tool storage box 25 are fixed to the top of the vehicle body 2. The cargo rack 24 and the tool storage box 25 are fixed to 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 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.

[0034] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
