Description

technical field [0001] The invention belongs to the technical field of underground fire-fighting equipment, and in particular relates to an underground multifunctional trackless fire-fighting vehicle. Background technique [0002] Coal mine fire is known as one of the five major disasters in mines, and its hazards are very serious. Not only the fire itself causes casualties and property losses, but it is also very likely to cause gas or coal dust explosions, inducing a series of chain disasters and causing greater damage to mines. s damage. [0003] The occurrence of underground fires in coal mines can be divided into external fires and internal fires. External fires are generally sudden, with no signs or no obvious signs in advance. They are mainly caused by electrical fires and tape fires. If it is not discovered and extinguished in time, it will often lead to a vicious accident, so it is particularly important to fire-fighting for underground fires caused by external cau...

AI Technical Summary

Problems solved by technology

[0004] The traditional fire-fighting equipment for external fires in underground mines is mostly fixed, which is time-consuming and labor-intensive to use, and it is easy to delay the best fire-fighting time, resulting in the deterioration of the fire development situation, resulting in greater casualties and property losses

Although there are also mobile fire-fighting equipment, such as the superfine dry powder cold aerosol fire extinguishing device described in the Chinese patent with the publication number CN101757754A, it can only use a single fire extinguishi
