Abstract

The present invention discloses a fire scene rescue equipment cooling device based on equipment self-spraying, comprising a three-way interface arranged at the middle end of the self-spraying pipeline, and a self-spraying nozzle fixedly installed at the top of the three-way interface, and the self-spraying pipeline is arranged at the outer end of the rescue equipment, and the outer end bolt of the rescue equipment is installed with a limit block. The fire scene rescue equipment cooling device based on equipment self-spraying is provided with a self-spraying nozzle and a self-spraying pipeline. By integrating the fire water inlet pipeline, the self-spraying pipeline, and the self-spraying nozzle, the fire water is used to perform self-spraying cooling on the equipment. When the nozzle sprays, a vertical upward water mist spraying method is adopted, which can increase the contact area between water and the equipment shell, and the water mist evaporates quickly to take away the heat of the equipment shell. At the same time, it can also reduce the ambient temperature near the equipment, thereby increasing the working time of the fire rescue equipment in the fire scene, improving reliability, reducing the utilization of water resources, and improving the rescue efficiency.
