Self-adaption elasticity continuous and slow descent fire protection escaping device

Abstract

A self-adaption elasticity continuous and slow descent fire protection escaping device comprises a housing, wherein a coiling shaft and a regulating shaft are arranged in the housing. A rotating speed adaptive regulation mechanism is arranged on the regulating shaft, the rotating speed adaptive regulation mechanism comprises a weight roller disc fixedly arranged on the regulating shaft, a friction disk I which is in sliding fit with the regulating shaft of unidirection and a friction disk II which is arranged relative to the friction disk I, wherein a weight roller arm assembly is arranged on a side, faced to the friction disk I, of the weight roller disc, the friction disk II is sleeved on the regulating shaft, and friction surfaces which are mutually matched are arranged between the friction disk I and the friction disk II. A spring seat is arranged on the housing, a spring which is used for the friction disk II being tightly pressed on the friction disk I is arranged in the spring seat, and a guide mechanism which is used for guiding the friction disk II and preventing the friction disk II from rotating is arranged between the spring seat and the friction disk II. A drive mechanism is arranged between the coiling shaft and the regulating shaft, a coiling disc and a handle mechanism which is used for driving the coiling disc to rotate are arranged on the coiling shaft, and a one-way clutch is arranged between the coiling disc and the drive mechanism.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to an adaptive elastic continuous slow-down fire-fighting escape device. Background technique [0002] At the scene of an accident such as a fire, when the personnel of a high-rise building cannot evacuate through the fire floor to escape downstairs, it is necessary to use the slow-down device to implement the rescue of the personnel on the high-rise building. Existing slow-down devices are generally fixedly installed on building windows, balconies or flat roofs of buildings. When a disaster occurs and cannot be evacuated, people can use the slow-down device to escape. [0003] The existing slow-down device has a complicated structure and needs to use a power source. When a disaster such as a fire occurs, the high-rise building usually loses power, which leads to the failure of the slow-down device that needs to use a power source and cannot be effective. The operat...

Problems solved by technology

[0003] The existing slow-down device has a complicated structure and needs to use a power source. When a disaster such as a fire occurs, the high-rise building usually loses power, which leads to the failure of the slow-down device that needs to use a power source and cannot be effective. The operation of the slow descending device is complicated. When the elderly or children use the slow descending device to escape, they are prone to panic. Complicated operations will slow down the speed of escape. If the operation is wrong, new dangers will occur
