A preset fire intercepting and extinguishing device

Abstract

The invention discloses a preset fire intercepting and extinguishing device, which comprises a bottom plate installed under the ground and a top plate above the ground, the top plate and the bottom plate are fixed by four fixing columns, electrical equipment is installed on the ground, and the electrical equipment is located under the top plate , a dry powder fire extinguishing device is installed on the top plate, and a heat-expandable airbag is folded between two adjacent fixed columns. Closely fit to form a sealed space, and at the same time cooperate with the dry powder fire extinguishing device to spray dry powder into the sealed space; the airbag expands when heated and forms a closed space with the top and bottom plates to prevent the fire from spreading. At the same time, the baffle on the airbag also compresses the switch handle to open the dry powder The fire extinguishing device completely extinguishes the fire in the confined space. The whole device does not need a power source to start, which can prevent the device from being unable to start due to the power being blown out when a fire occurs.

Description

technical field [0001] The invention relates to the field of fire extinguishing devices, in particular to a preset fire intercepting and extinguishing device. Background technique [0002] Some Internet companies now have their own servers. When these servers need to be plugged in a lot of wires, the probability of a short circuit causing a fire is greatly increased. When a fire occurs, the burnt wires will be scattered on the ground. At this time, people will accidentally step on these wires when extinguishing the fire, causing electric shock injuries. Further spread, strengthened economic loss, so be badly in need of a kind of preset fire intercepting fire extinguishing device now. Contents of the invention [0003] Aiming at the situation in the background technology, the present invention provides a preset fire interception and extinguishing device, which effectively solves the problems in the background technology. [0004] In order to solve the above technical prob...

[0002] Some Internet companies now have their own servers. When these servers need to be plugged in a lot of wires, the probability of a short circuit causing a fire is greatly increased. When a fire occurs, the burnt wires will be scattered on the ground. At this time, people will accidentally step on these wires when extinguishing the fire, causing electric shock injuries. Further spread increases the economic loss, so now there is an urgent need for a preset fire interception and fire extinguishing device
