A spin-stabilized fire extinguishing disc for firefighting

Abstract

The invention belongs to the field of automatic fire extinguishing, and particularly relates to a spin-stabilized fire extinguishing tray for fire fighting, which includes a handle mechanism, a rope winder, a positioning box, and a fire extinguishing mechanism, wherein the positioning box installed on the side of the handle mechanism has a fire extinguishing mechanism. The box has a limit structure that fixes the position of the fire extinguishing mechanism and prevents the fire extinguishing mechanism from slipping out of the positioning box; the fire extinguishing mechanism in the present invention rotates when moving to the fire site, effectively maintaining its stability during flight to ensure fire extinguishing The bottom cover in the mechanism always keeps facing the direction of the flame; when the fire extinguishing mechanism reaches the fire range and self-explodes, the internal dry powder fire extinguishing agent is all concentrated on the flame through the broken bottom cover; because the bottom cover part of the fire extinguishing mechanism is blown, the dry powder The fire extinguishing agent is concentratedly sprinkled on the flame from one side of the disk, so the utilization rate of the dry powder fire extinguishing agent is effectively improved, and its fire extinguishing efficiency is improved, and the fire extinguishing effect is better.

Description

Technical field[0001]The invention belongs to the field of automatic fire extinguishing, and particularly relates to a spin-stabilized fire extinguishing pan for fire fighting.Background technique[0002]The traditional fire extinguishing ball device consists of a foam shell, a built-in dry powder drive device, and ABC dry powder fire extinguishing agent. The outside of the fire extinguishing ball device is wound with a cross-shaped lead wire. When the outer lead wire is ignited, the driving medium is activated, and the shell rapidly expands and ruptures. The dry powder fire extinguishing agent is quickly sprayed into the protected area and quickly diffused around, forming a fully submerged fire extinguishing state. It is extinguished by the physical and chemical effects of dry powder fire extinguishing agent. Both the elderly and the children can throw the fire extinguishing ball to the designated area. Once the flame touches the fuse, it will be quickly ignited and started within 3s...

AI Technical Summary

Problems solved by technology

[0003] If the force of throwing the fire extinguishing ball is greater, the fire extinguishing ball will not be able to self-explode due to crossing the flame and cannot reach the fire range, thus failing to achieve effective fire extinguishing

Traditional fire extinguishing balls are only suitable for ground fires. If aerial cables catch fire or building exterior wall insulation materials catch fire, traditional fire extinguishing balls for throwing will not be able to effectively extinguish the fire in the air or walls because they cannot fully contact the flames.

In addition, the fuse arranged on the spherical surface of the traditional fire extinguishing ball does not have good waterproof measures, and the fuse is easily damp, which makes the fire extinguishing ball ineffective.
