Description

Automatic fire extinguisher set {AUTO EXTINGUISHER SET}

The present invention relates to an automatic fire extinguisher set, and more particularly, in a state in which a pressure pin for opening the drug opening of the fire extinguisher is connected with a separate actuator, the actuator automatically operates by thermal sensing when a fire occurs It relates to an automatic fire extinguisher set capable of automatically opening an opening.

In general, a fire extinguisher is used when extinguishing a fire at an early stage, and fires are classified into general fires, oil fires, electric fires and metal fires according to their properties. This makes it possible to effectively extinguish the fire.

Such fire extinguishers are again divided into powder fire extinguishers, carbon dioxide fire extinguishers, halon and gas fire extinguishers and solid aerosol fire extinguishers according to the extinguishing agent charged therein.

In addition, according to the method of operation, it is largely divided into a manual fire extinguisher and an automatic fire extinguisher.

These manual fire extinguishers are fire extinguishers that are most commonly seen as fire extinguishers that eject a fire extinguishing agent by pulling out a safety pin and gripping the lever with your hand.

And, an automatic fire extinguisher is a fire extinguisher that detects heat or smoke and automatically releases a fire extinguishing agent to extinguish a fire.

And, the automatic fire extinguisher is divided into an electric type and a mechanical type, and the electric type has a configuration to burn the fire extinguishing agent by an electric ignition device by supplying an electrical signal when it detects heat or smoke, and the mechanical type uses heat when it detects heat It has a configuration to operate the mechanical igniter and burn the extinguishing agent with the flame generated from the mechanical igniter.

On the other hand, schematically looking at the fire extinguishing device of an example of the conventional mechanical automatic fire extinguishing device, a ball is usually fixed by a fixed ball, and the fixed ball is supported by a fusible metal.

In addition, the fusible metal is in contact with the heat conduction plate, and the ball is supported by an elastic means, which supports the ball in a compressed state inside the passage in which the ball moves.

Then, when a fire occurs, heat is transferred to the heat conduction plate mounted on the body of the sensing unit to increase the temperature, and when heat over a certain temperature is transferred, the fusible metal in contact with the heat conduction plate is melted.

The fusible metal melted by receiving heat flows out of the fusible metal exposure hole, and the fixed ball moves to the space where the fusible metal was, thereby releasing the restraint of the fusible metal.

In addition, the ball, which has been restrained by the fixing ball and then released from the restraint, rapidly moves downward along the passage due to the elasticity of the elastic means, and the submerging unit formed at the lower end of the ball applies a physical impact to the primer.

At this time, the detonator explodes, the initiator is ignited due to the explosion of the detonator, the initiator container part stopper is ruptured by the pressure and heat generated by the ignition of the initiator, and the flame is transferred to the ignition agent The ignition agent is ignited.

And, as the ignition agent ignites, the solid aerosol extinguishing agent is combusted to generate a solid extinguishing aerosol, and the solid aerosol moves downward and passes through the coolant upper perforated network, and is cooled while passing the coolant, and the coolant lower perforated network and the discharge perforated network discharged out through

Then, the discharged solid aerosol performs a fire-extinguishing function by blocking oxygen in the fire area, or by blocking the chain reaction of the fire.

However, such a conventional automatic fire extinguisher has components for automatically operating the fire extinguisher, that is, a ball, a fixed ball, a fusible metal, a fusible metal support means, a heat conduction plate, an elastic means for supporting the ball, and the ball moves. A passage, a fusible metal exposing hole for exposing the fusible metal, a sinking part and a primer formed at the bottom of the ball, an initiator ignited by the detonation of the primer, a stopper in the initiator container part, and a lower coolant through which a solid fire extinguishing aerosol passes Since it consists of complex components such as a perforated network and a perforated discharge network, it is difficult and complicated to manufacture a fire extinguisher and has problems such as an increase in the number of work hours and an increase in manufacturing cost due to an increase in the number of parts.

In addition, since the heat generated during a fire depends only on the heat conduction plate installed in the separate sensing unit and there is no additional heat sensing support means for additionally supporting the heat sensing, the heat sensing speed according to the fire is relatively slow. As a result, there were problems such as a significant decrease in reliability of the device, etc. as a result of insufficient rapid fire response.
