Self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill

Abstract

The invention relates to the technical field of electric drills, in particular to a self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill. The self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill comprises a machine body, a handle is fixedly arranged at the lower end of the machine body, a storage battery is fixedly arranged at the lower end of the handle in a buckled mode, and the handle is provided with a battery dismounting button for controlling the dismounting of the storage battery. According to the self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill provided by the invention, the battery is adopted for supplying power, so that the self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill is suitable for efficient operation in a short time, and the self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill is light in weight and easy to carry; the self-cooling fire-fighting liquid nitrogen fire-extinguishing electric drill is suitable for being carried by firefighters and can be suitable for most fire scenes; and therefore, the self-cooling fire-fighting liquid nitrogen fire-extinguishing electric drill can also be used at home, and is convenient and safe. The liquid nitrogen element is added, cooling treatment can be carried out while fire extinguishing is carried out, the temperature is reduced to be below an ignition point while open fire is extinguished, and fire is prevented from being ignited again; and the novel drill bit is adopted and is different from an existing drill bit in the market, the disengagement type drill bit is adopted, internal combustible substances can be effectively prevented from making contact with external oxygen, and the backdraft prevention effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric drills, in particular to a self-cooling liquid nitrogen fire-fighting electric drill. Background technique [0002] With the rapid development of the social economy and the continuous improvement of living standards, various buildings such as buildings, terraces, private houses, storage, etc. enrich people's lives. Due to fire-fighting needs, public fire-fighting facilities are widely used in places where the public gathers, people are dense, and labor-intensive. Deflagration is a mutation phenomenon that may appear in the peak period, which will cause the fire to expand rapidly and endanger personal and property safety. A small fire at a certain moment will burst out suddenly, forming a raging fire that can sweep everything. [0003] In general building interiors, there are various organic solid combustible substances, such as wood and plastic furniture, books and paper, and cotton and linen fa...

AI Technical Summary

Problems solved by technology

They are constantly mixed with air, and when they reach the explosion limit, they will explode under the action of high-temperature flames, endangering the safety of life and property. Therefore, it is necessary to design a self-cooling fire-fighting liquid nitrogen fire extinguishing electric drill to improve the above problems
