Description
Technical Field
The invention relates to the field of underground space disaster prevention and reduction, in particular to an underground building fire-fighting safety elevator.
Background
The underground building fire elevator is an elevator which is used for fire extinguishing and rescuing by fire fighters when a fire disaster occurs in the underground building and has a certain function. Therefore, the fire elevator has higher fire protection requirements, but most of the existing fire elevators are only used for rescuing firefighters and are not opened at ordinary times. When the underground building has a fire, the common elevator is stopped, and people suffering from the fire are difficult to evacuate from the underground space in time. At present, China is vigorously developing underground spaces, underground building fire elevators are very rare in the true sense, and underground building fires can cause more damage compared with overground buildings.
The underground space has the following characteristics: firstly, because the smoke diffusion channel is limited, most of generated smoke is accumulated in a limited space, so that the smoke density of the underground building fire is higher than that of a ground building in a unit space; in addition, fresh air of the underground building is slowly supplemented, and as a large amount of substances made of raw materials such as rubber, plastics, nonferrous metals, wood, paint, high molecular compounds and the like stored in the underground building cannot be fully combusted, highly toxic gases such as hydrogen chloride and the like are generated, the toxicity of the highly toxic gases is 20 times that of carbon monoxide, and if people in the underground building cannot be evacuated in time, the casualties can be caused by the suction of a trace amount of hydrogen chloride gas, which is one of the main causes of casualties in the fire of the underground building; at present, most underground buildings are used for entertainment, commerce and traffic functions, the flow of people is huge, the goods are miscellaneous, the safety exit is limited, and once a fire disaster happens, people cannot evacuate in time, so that great loss is caused; after the fire disaster happens to the underground building, because smog is relatively stable in the inclosed space, the heat that the burning produced can not get timely propagation, make indoor temperature rise gradually and under high to lead to the building internal pressure increase, can appear "bombing" phenomenon under this condition (when receiving exogenic action to collapse or when collapsing naturally, prominent intensity of a fire forms "bombing") and can be fast extend all around along the passageway, will ordinary safety exit seal, cause personnel's life danger.
Therefore, the underground building fire-fighting safety elevator is designed aiming at the condition that people cannot escape from the existing ordinary elevator when a fire disaster happens to an underground building, and most people cannot escape in time.
Disclosure of Invention
The invention aims to provide a fire-fighting safety elevator for an underground building; when the underground building is in fire, the powerful ventilation device is automatically opened, the air quality in the elevator shaft is ensured, the safe operation of the elevator in the fire can be realized, and when the elevator operates to the top of the shaft, people suffering from a disaster can withdraw from the underground building by opening the electric escape door and through the vertical safety ladder arranged on the No. three wall of the shaft, so that the people suffering from the disaster can safely escape. If the elevator suddenly breaks down in the operation process, people trapped in the elevator can open the electric escape door in time and evacuate the underground building through the vertical safety ladder.
