Step-by-step grabbing climbing fire-fighting escape capsule

Abstract

The invention relates to a step-by-step grabbing climbing fire-fighting escape capsule, which is characterized by comprising a capsule body and at least four climbing mechanisms, wherein every two climbing mechanisms form one group and are symmetrically arranged at two sides of the capsule body; each climbing mechanism is provided with a grapnel device; and the climbing mechanism drives the grapnel device to go up and down; and the grapnel devices arranged on upper and lower groups of the climbing mechanisms alternately grab a window at upper and lower floors to realize the raising and descending of the capsule. Compared with the prior art, the invention has beneficial effects: 1) the climbing mechanisms move alternately, and drive the capsule body to move up and down along the outer wall of high-rise buildings by means of the window; 2) the grapnel device can firmly grapple the windows of the buildings; 3) the capsule has independent space which can bear firemen to rapidly reach the fire floor and can carry trapped people to enable the people to fast escape from the fire; 4) as long as the windows supplied for the grapnel device exist, the device can go up at any height; and 5) the device can be matched with a high pressure fire hose to replace an aerial ladder truck for disaster relief in the scene of a fire.

Description

technical field [0001] The invention relates to the field of fire-fighting and life-saving facilities, in particular to a step-and-grab climbing fire-fighting and life-saving cabin. Background technique [0002] High-rise buildings are tens of meters high, or even hundreds of meters high. High-rise fire protection is a worldwide problem. When a fire breaks out, due to the limitations of fire trucks, it is generally not possible to directly use fire trucks to pump water from the outdoor fire water source to high-rise fire floors. Usually Mainly rely on the indoor fire hydrant system of high-rise buildings to fight the fire. When a fire breaks out in a high-rise building, the water consumption needs to be more than 80L / s, or even exceed 100L / s. The amount of water and water pressure inside are difficult to meet the requirements. [0003] Therefore, when a fire breaks out in a high-rise building, the combination of inside and outside is generally used to extinguish the fire, ...

AI Technical Summary

Problems solved by technology

If the fire elevator cannot be used due to a power outage, and the height of the ladder truck is not high enough, the firefighters can only go up to the burning floor from the indoor stairwell to put out the fire with full armor.

Because firefighters need to climb high with heavy loads, their physical strength is extremely exhausted, which will seriously affect the speed and efficiency of fire fighting operations

If the victims escape from the stairs, they are exposed to toxic fumes for too long, and they are very prone to respiratory burns and poisoning, and lose their lives on the spot. Even if they run out of the fire scene, the harm of poisonous fumes to people is fatal
