Description

Extinguisher operator with a low melting metal

The present invention relates to a fusible metal type fire extinguisher operating device, and more particularly, a fusible metal which is configured to automatically eject a fire extinguishing agent using a metal which is easily melted by heat so as to extinguish the fire at the beginning of the fire. It relates to a type fire extinguisher operating device.

In general, most buildings are equipped with a fire extinguisher for the purpose of delaying the spread of the fire until the initial fire or fire truck is dispatched when a fire occurs, a typical fire extinguisher is usually provided with a cylindrical fire extinguisher container filled with a fire extinguishing agent, The extinguishing agent is sprayed by removing the safety pin by manual operation.

However, such a cylindrical fire extinguisher is occupied by occupying a part of the indoor space, and thus may interfere with human movement or may not visually harmonize with the surrounding indoor interior.

In recent years, in view of the problems described above, a fire extinguisher in the form of a panel has been developed so that a fire extinguishing device is installed in a wall, a ceiling, or a door in the room so that the extinguishing agent can be automatically sprayed in the event of a fire.

However, such a panel type fire extinguisher is usually made of a plug using a fusible metal such as lead or lead alloy, which is easily melted at a relatively low temperature due to the heat of the fire so that the extinguishing agent can be automatically ejected. As the plug is melted and removed by heat, the operation of the device is automatically performed to eject the extinguishing agent. According to the conventional operating device, in order to melt and remove the plug by heat, flame is directly contacted with the plug or Since the fire extinguisher is often operated in a situation where the fire has already been spread, it is difficult to extinguish the fire at the beginning of the fire, and thus, there is a problem in that the operation reliability is lowered.

The present invention is to solve the problems as described above, the present invention is provided to quickly transfer the heat to the fusible metal which is easily melted by heat in case of fire is provided to automatically eject the extinguishing agent, thereby Providing a fire extinguisher operating device to extinguish the fire in the early stage of the fire, and also to provide a safe operation when transferring heat to fusible metals, which not only provides excellent operation reliability but also reduces the risk of additional fire. It is to provide a metallic fire extinguisher operating device.

According to a feature of the invention, it is automatically operated by heat is provided to open the inflator 21 in the form of a sealed container filled with pressurized gas, the pharmaceutical container 20 or the chemical hose by the pressurized gas of the inflator 21 A fire extinguisher operating device configured to eject a fire extinguishing agent in a fire;

The inflator 21 is coupled to one side and at the same time is provided with an injection tube 32 extending to inject the pressurized gas of the inflator 21 into the drug container 20 or the drug hose, the drug container 20 on the other side Or an operating body 31 having an exhaust pipe 33 extending to extend the extinguishing agent in the chemical hose;

A triggering mechanism (50) built in one side of the operating body (31) to strike the pressurized gas in the inflator (21);

A valve (60) built in the state in which the discharge pipe (33) is closed on the other side of the operating body (31), and linked to the operation of the trigger mechanism (50) to open the discharge pipe (33);

A nozzle (70) provided at an end of the discharge pipe (33) to eject the extinguishing agent in the medicine container (20) or the medicine hose to the outside;

Is coupled to one side of the operating body 31 is supported so that the operation of the trigger mechanism 50 is suppressed, at least a part of the heat is melted by the heat is composed of a metal including lead or lead alloy to release the support of the trigger mechanism A plug 40;

It is formed in the state wound on the thermal plug 40 is extended to a portion near the ignition point, fusible metal characterized in that it comprises a conductive wire 41 is ignited by a fire to melt the thermal plug 40 Type fire extinguisher actuators are provided.
