Special fire engine with circular cooling function

Abstract

The invention provides a special fire engine with a circular cooling function. The special fire engine comprises a car body, and further comprises a cooling cavity arranged on the outer surface of thecar body, a water storage tank arranged at the bottom of the car body and a water pump for feeding water in the water storage tank into the cooling cavity; and the water storage tank communicates with the cooling cavity. In the special fire engine with the circular cooling function, the water storage tank at the bottom of the car body communicates with the cooling cavity; the water in the water storage tank is fed into the cooling cavity through the water pump for cooling the outer surface of the car body; the cooling water flows back into the water storage tank from the cooling cavity to form a circulating water loop; and compared with the prior art, the special fire engine with the circular cooling function saves the water consumption, and prolongs the fighting time in a fire scene.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting vehicles, and relates to a fire-fighting vehicle, in particular to a special fire-fighting vehicle with a circulating cooling function. Background technique [0002] After a fire breaks out, traditional fire trucks need to be close to the fire source to extinguish the fire. Special fire trucks restructured from special vehicles such as armored vehicles are widely used in urban commercial complexes, petrochemical plants, etc. due to their strong ability to survive fires. Fire fighting of large and complex buildings. When the special fire truck enters the fire scene for fire investigation, rescue, and fire fighting, the high-temperature radiation heat of the fire scene will cause destructive damage to the steel plate of the car body, and the strength of the steel plate will drop significantly after being heated, affecting the safety of the vehicle. Therefore, it is necessary to insulate and c...

AI Technical Summary

Problems solved by technology

In order to prolong the combat time of special fire trucks in the fire scene, the current common practice is to spray fire-resistant paint on the outer surface of the steel plates of special fire trucks, and cover the inner surface with heat-insulating cotton to realize the heat insulation of the steel plates of the car body. It has a good heat insulation effect, but the implementation cost is too high; at the same time, sprinklers are used to spray the outer surface of the steel plate to cool down, which is limited by the space in the car and the volume of the water tank is small. Continuous spraying leads to short residence time in the fire scene
