High-altitude projection fire extinguishing equipment

Abstract

The invention provides high-altitude projection fire extinguishing equipment. The equipment comprises a bracket, a projection device, a crushing device positioned above the projection device and connected with a feeding port of the projection device, a feeding box positioned above the crushing device and connected with a feeding port of the crushing device, a first hot air balloon positioned abovethe feeding box and a first pull rope connected between the first hot air balloon and the bracket, wherein a discharge port of the projection device is vertically arranged downwards or obliquely arranged downwards relative to the horizontal plane. By arrangement of the first hot air balloon, the projection device can be drawn to a position right above or lateral above a fire site to project sandfrom top to bottom. The projection force needs not to overcome gravity action, and can form joint force with gravity to push the sand to move down. The grounding impact force is relatively large, barriers can be easily broken through to cover flames accurately, and strong airflow can also be formed to extinguish the surrounding flames on the basis of coverage of combustibles and prevention of combustion of the combustibles, so that fire extinguishing efficiency is relatively high.

Description

technical field [0001] The invention relates to emergency rescue equipment, in particular to high-altitude projectile fire extinguishing equipment. Background technique [0002] Projectile fire extinguishing equipment is a kind of fire extinguishing equipment that uses solid materials such as sand and soil as fire extinguishing materials, and throws them onto the fire source by means of projection to cover combustibles. Because it can be obtained locally, it is widely used in various fields such as forest fire extinguishing. In fire fighting in outdoor environments. [0003] The Chinese invention patent application with the publication number CN109731256A discloses a forest fire extinguishing robot and a method for realizing fire extinguishing by throwing soil and using local materials. The body is used to break the soil block, and the soil-breaking mechanism is provided with an outlet; the excavating mechanism is supported by the car body, and the excavating mechanism can ...

AI Technical Summary

Problems solved by technology

However, this forest fire-fighting robot throws the sand from the ground to the fire place, and the trajectory of the sand in the air is parabolic. It is located at the highest position where the sand is projected, and has no direct relationship with the projectile force. The impact force on the ground is relatively small, and the sand is easy to disperse under the action of obstacles such as branches, which affects the fire extinguishing efficiency.
