fire extinguishing ball

Abstract

The invention discloses a spraying fire extinguishing ball. The spraying fire extinguishing ball comprises an outer shell body and fire extinguishing agent powder; the outer shell body is spherical, the bottom of the outer shell body is provided with a balancing weight, and a powder storage shell body is arranged above the balancing weight; a supporting cushion capable of changing the size along with the temperature is arranged under the powder storage shell body; the fire extinguishing agent powder is located in the powder storage shell body; a gas generation device is arranged in the powderstorage shell body; the upper portion of the position, right facing the balancing weight, of the outer shell body is provided with a spraying opening; the side face of the outer shell body is providedwith a plurality of auxiliary spraying holes; the powder storage shell body is provided with a matched opening; the side wall of the powder storage shell body is further provided with auxiliary matching holes which are located below the auxiliary spraying holes; and the spraying opening is internally provided with a sealing plug made of a heat-sensitive material. The spraying fire extinguishing ball has the advantages that the supporting cushion, the auxiliary matching holes and the auxiliary spraying holes are matched, and the effective utilization rate of a fire extinguishing material is high; fire extinguishing points of the auxiliary spraying holes are accurate, and the fire extinguishing efficiency is high; and the spraying opening of the outer shell body can be always reset to the upward position, and the fire extinguishing effect is reliable.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a spray fire extinguishing ball. Background technique [0002] The fire extinguishing ball is suitable for fire situations where people are difficult to approach, and has the characteristics of simple and safe fire extinguishing. At present, in most throwing fire extinguishing balls or fire extinguishing bombs, the fire extinguishing material is blown out in the form of an explosion, covering the fire point. Due to the huge impact of the explosion, a large amount of fire extinguishing material is blown away from the fire point, so it has not been effectively used. , and the explosion may also cause personal injury. Some fire extinguishing balls adopt detonator fire explosives etc. to explode the shell of the fire extinguishing ball so that the fire extinguishing medium is dispersed in the fire field, which also has potential safety hazards. [0003] For exa...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the disadvantages that the existing fire extinguishing ball extinguishes fire in the form of explosion, which is likely to cause potential safety hazards and has low application efficiency of fire extinguishing materials. It provides a spray fire extinguishing ball, which is sprayed to extinguish the fire after being thrown at the fire. The effect of covering the fire point is good, and the effective utilization rate of fire extinguishing materials is high
