A dual-function switching fire extinguisher safety device

Abstract

The invention discloses a double-function switching fire extinguisher security and protection device. The double-function switching fire extinguisher security and protection device structurally comprises a pressing handle, a safety pin, a spraying cylinder, a pressure gauge and a fire extinguishing type switching device. According to the double-function switching fire extinguisher security and protection device, a path for spraying sodium bicarbonate dry powder inside a sodium bicarbonate dry powder cavity is changed through a rotating disc, so that the difference of fire extinguishing forms of a fire extinguisher is achieved, in the case of one kind of fire extinguishing form, the dry powder is sprayed out through a dry powder guide pipe and is directly used for fire extinguishing, in thecase of the other kind of fire extinguishing form, the sodium bicarbonate dry powder enters a concentrated liquid carbon dioxide valve bottle through a communicating pipe and a connecting pipe, so that carbon dioxide foam is generated for extinguishing fire, and an osmotic pressure blocking plate is used for playing the roles in osmotic pressure and preventing the diffusion of the sodium bicarbonate dry powder; an indication rubber block is used for accurately prompting the rotating limit of an operator, and preventing the situation that a first flange and second flange are not connected, meanwhile, an S-pole magnet block and an N-pole magnet block facilitate seamless lamination between the first flange and the second flange, so that the sodium bicarbonate dry powder is prevented from scattering everywhere; and therefore, the double-type fire extinguisher can adapt to more different types of fires and does not occupy too much space positions.

Description

technical field [0001] The invention relates to the security field, more precisely, it is a dual-function switching fire extinguisher security device. Background technique [0002] Modern factories are often equipped with fire extinguishers in order to prevent fires before they happen. Since there are many electrical equipment in the factory, they are often equipped with dry powder fire extinguishers that can quickly extinguish fires caused by electricity, which has the following disadvantages: [0003] At present, there are also flammable substances such as lubricating oil in the factory. When the container storing lubricating oil catches fire, the oil in the container is easily washed out due to the large impact force of the dry powder fire extinguisher, causing the fire to spread. This makes the dry powder fire extinguisher It cannot be used. At this time, a foam fire extinguisher is needed to quickly extinguish the fire in the container, while the factory is equipped wit...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a dual-function switching fire extinguisher security device to solve the problem in the prior art that when the container storing lubricating oil catches fire, the impact force of the dry powder fire extinguisher is relatively large. The oil in the container rushes out, causing the fire to spread, which makes the dry powder fire extinguisher unusable. At this time, a foam fire extinguisher is needed to quickly extinguish the fire in the container, and the factory is equipped with a dry powder fire extinguisher, which can only be watched. Watch the fire spread, and if there are too many fire extinguishers in the factory, it will cause a waste of space, and it is easy to use the wrong type of fire extinguisher in a panic, resulting in more serious consequences
