Trolley type fire extinguisher

Abstract

The invention relates to the technical field of fire extinguishers, in particular to a trolley type fire extinguisher. The fire extinguisher comprises a gas storage mechanism and a material storage mechanism and further comprises a trigger mechanism, wherein the gas storage mechanism guides high-pressure gas into the material storage mechanism through triggering of the trigger mechanism to achievespraying of the fire extinguisher; the gas storage mechanism comprises a gas storage cavity, the front end of the gas storage cavity is connected to the trigger mechanism, and the rear end of the gasstorage cavity is connected to an inflating device; the trigger mechanism comprises a gas spray tube fixedly connected to the gas storage cavity through threads, a piston is arranged in the gas spraytube, and the gas spray tube is in sliding fit to the piston; the material storage mechanism comprises a transition cavity formed in the outer circumference of the gas spray tube, the transition cavity is fixed to the outer circumference of the gas spray tube in a threaded connection mode, and a material storage bin is fixedly connected to the tail end of the transition cavity. Through long-distance operation, safety of fire extinguishing personnel is guaranteed to the maximum extent; and a large amount of fire extinguishing powder is sprayed instantly to extinguish flames, so that action issensitive, and the fire extinguishing area is large.

Description

technical field [0001] The invention relates to the technical field of fire extinguishers, in particular to a cart-type fire extinguisher. Background technique [0002] Existing fire extinguishing device is varied, as dry powder fire extinguisher, foam fire extinguisher, carbon dioxide fire extinguisher. Most of the above-mentioned existing fire extinguishers are continuous output fire extinguishers, especially when the fire intensity is relatively large, they often cannot achieve instant effective fire extinguishment. General fire extinguishers require fire extinguishers to be close to the fire area and spray fire extinguishing powder on the root of the flame to extinguish the fire, especially for fires in limited and closed spaces. After personnel enter, high temperature, toxic and harmful gases will bring safety hazards to fire extinguishers. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the existing fire extinguishers such as small p...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned deficiencies in the prior art, such as small powder storage capacity, low spraying efficiency, and unguaranteed safety of fire extinguishers, the present invention provides a cart-type fire extinguisher, which can maximize the safety of fire extinguishers through remote operation. Instantly spray out a large amount of fire extinguishing powder to extinguish the flame, the action is sensitive, and the fire extinguishing area is large
