Description

Semi-automatic directional fire extinguishing device

Technical Field

The invention belongs to the technical field of fire extinguishing devices, and particularly relates to a semi-automatic directional fire extinguishing device.

Background

The fire extinguisher is a portable fire extinguishing tool. Chemical substances are placed in the fire extinguisher for saving and extinguishing fire. The fire extinguisher is one of common fire-proof facilities, is stored in public places or places where fire disasters may happen, and different fire extinguishers of different types are filled with different components and are specially designed for different fires. Care must be taken in use to avoid adverse effects and risks.

The dry powder fire extinguisher is filled with a dry powder fire extinguishing agent. The dry powder fire extinguishing agent is dry and easy-to-flow fine powder for extinguishing fire, and consists of inorganic salt with fire extinguishing effect and small amount of additive, which are dried, crushed and mixed to form fine solid powder. Compressed carbon dioxide is used for blowing out dry powder (mainly containing sodium bicarbonate) to extinguish fire, but when a fire disaster occurs, the fire spreading speed is high, and heat waves generated by the fire disaster cannot be close to the fire disaster, so that the fire source cannot be cut off in time, the fire disaster is accelerated to spread, and the fire area is enlarged.

In order to separate the fire source and keep away from the fire source to accurately block the fire source, in the existing treatment method, a high water gun or a portable fire extinguisher is used for extinguishing and cleaning the fire, so that the problem of fire relief is solved.

Based on the above description, and combine current fire extinguisher, utilize wall-hanging and trigger formula design, adopt to launch the dry powder to fire source department effect, then, study improvement to current dehumidification technique and disappearance, provide a semi-automatic directional extinguishing device to reach the purpose that more practical value nature has more in term.

Disclosure of Invention
