fire extinguishing device

Abstract

The invention provides a fire-extinguishing device. The composite fire-extinguishing device comprises a spraying fire-extinguishing assembly (100), a CO2 fire-extinguishing assembly (200) and a spraying assembly (300). The fire-extinguishing device suppresses fire inside an obstacle, such as a wall, by spraying a mixture including the fire extinguishing solution and abradant and effectively extingushing fire of various fire sites by selectively spray fire extinguishing agent or CO2 according to the fire type. When a core layer of a wooden building is on fire, the mixture including the fire extinguishing solution and abradant is sprayed to penetrate the steel and dust layer, the obstacle layer, and CO2 gas is sprayed to an internal core layer to extinguish fire. Fire can be extinguished with the smothering effect of CO2, so that the purpose of extinguishing fire while minimizing damage of wooden building can be achieved.

Description

technical field [0001] The present invention relates to a fire extinguishing device for fire extinguishing. The composite fire extinguishing device for fire extinguishing of the present invention sprays a fire extinguishing agent into the interior of the fire extinguishing device in the state of spraying a mixture of fire extinguishing water and abrasives and penetrating through barrier layers such as obstacles, walls, etc. For internal fires, spray fire water or CO selectively according to the fire scene 2 The gas can effectively extinguish the fire. Background technique [0002] Recently, with the deepening and popularization of human society's understanding of safety and fire, fire extinguishing devices have received more and more attention. Therefore, many high-rise buildings have prepared a thorough and perfect fire extinguishing system for fire. However, buildings or wooden buildings with a long history not only cause huge property losses but also often cause loss of...

Problems solved by technology

[0005] As mentioned above, the roof structure of a wooden building is waterproof and can protect the interior of the wooden building from external disasters (moisture, water leakage), but it will become a major obstacle to fire extinguishing when a fire occurs inside thing

[0006] That is, the waterproofing function was enhanced by steel ash compaction to prevent water leakage from the outside to the inside, but when the core layer was burned by flames when the internal beams caught fire and spread to the roof, the fire was carried out by the steel on the upper part of the core layer. The impact of the steel ash layer of the ash compaction construction is not exposed to the outside, but the smoldering core layer makes it impossible for the outside to know the situation of the flame spreading to the outside, and the upper part needs to be removed in order to extinguish the flame burning to the core layer After removing the filling soil and lime, spray fire-fighting water or fire-extinguishing materials towards the core layer, which increases the difficulty of fire-fighting operations.

On the other hand, the back-draft phenomenon occurs when the cover plate under the core layer is removed, which makes the on-site firefighters bear the risk of safety accidents
