A multi-level connected anti-smoke fire chute

Abstract

The invention provides a multi-stage connected anti-smoke fire-fighting slide, which belongs to the related technical field of fire-fighting equipment, and solves the technical problems of poor buffering and anti-collision effects of the fire-fighting slide and easy smoke collection. The present invention comprises main slides, several elastic buffer slides are arranged between the main slides, the upper end of the main slides is provided with a smoke-proof inlet, the side of the main slide is provided with several branch slides, and the end of the branch slides is provided with There is a smoke-proof entrance, and the lower end of the bottom elastic buffer slideway is provided with a right-angle elastic drop pocket, and the smoke-proof entrance is set on the balcony of each floor. The present invention adopts the cooperation of the main slideway with several elastic buffer slideways and right-angle elastic drop pockets, so that the survivors can fall quickly, and the buffer force is strong, so as to avoid falling impact and injury. It can insulate heat and prevent smoke from entering the main slideway; the torsion spring is used to keep the smoke-proof door in a normally closed state.

Description

technical field [0001] The invention belongs to the related technical field of fire fighting equipment, and relates to a fire fighting slideway, in particular to a multi-level communication anti-smoke firefighting slideway. Background technique [0002] Nowadays, with more and more people pouring into cities, man-made fires have become one of the most frequent and common major disasters that threaten public safety and social development. Due to the characteristics of traditional high-rise buildings, elevators and The stairs become the straight passage for the fire to spread when a fire occurs. Once a fire occurs somewhere in the building, the fireworks will often go up from the stairs, making it impossible for people on high floors to escape from the stairs, which directly affects the safety of the entire building. Evacuation, rescue and fire fighting are quite difficult. Therefore, while high-rise buildings show human progress and rapid social and economic development, cru...

Problems solved by technology

[0003] However, most of the existing fire-fighting slides use palms or elbows to rub against the bag slides, which is difficult to control for escapees from high-rise buildings, and the risk factor is high, and the fire-fighting slides can only be single-layer and single-level. The passage cannot meet the needs of each floor, and at the same time, the fire chute is easy to collect smoke, which is not conducive to escape
