Description

Technical Field

[0001] The utility model relates to the technical field of dangerous goods transport vehicles, in particular to a cooling spray device for dangerous goods transport vehicles. Background Art

[0002] A transport truck is a vehicle used to transport goods, usually equipped with a cargo box or a load-bearing platform, used to load and transport various types of goods. According to different uses and requirements, the types and designs of transport trucks are also different. A hazardous goods transport truck is a special vehicle with an open cargo box top, a front exhaust pipe and a spark-proof device for transporting petrochemicals, explosives, firecrackers and other hazardous goods. During the transportation of hazardous goods, the liquid is extracted and sprayed onto the tank body through a hydraulic pump or an air pump to achieve cooling to avoid the natural explosion of hazardous goods. An additional power source is required to cool the tank body, which increases the transportation energy consumption and transportation cost of the transport truck.

[0003] In order to solve the above problems, a utility model patent with publication number CN219903995U discloses a cooling spray device for a dangerous goods transport vehicle. The airflow generated by the movement of the transport vehicle body drives the fan to rotate, and cooperates with the first pulley and the second pulley of different diameters to provide power for the circulating pump, so that the liquid in the water collecting tank is extracted and sprayed onto the storage tank through the spray pipe and the nozzle to cool it down. No additional power is required, which reduces energy consumption and cost, and is energy-saving and environmentally friendly.

[0004] During the use of the above-mentioned transport vehicle spray device, the nozzle is usually in a fixed position, so that the spray range is small, and it is difficult to spray the nozzle back and forth for cooling according to the length of the dangerous goods, so the cooling effect on the dangerous goods is relatively low, reducing the effect and efficiency of spraying cooling. When the spray device is in use, the sprayed water usually flows and scatters everywhere, and it is difficult to collect the sprayed water for recycling. When spraying dangerous goods, due to the phenomenon of dust and impurities in the air, some dust usually adheres to the surface of the dangerous goods tank, which is washed by the spray device and flows down with the water. Because the filtering effect of the water flow after convection is relatively weak, it is difficult to filter the reused water flow, which reduces the quality of the reflux water flow and easily causes the reflux water pipe to be blocked. At the same time, it is not convenient to clean the surface of the filter plate after filtration, which easily causes the filter plate to be blocked, reducing the speed and efficiency of the water reflux.
