Description

Compatible lift

Technical field

The present invention relates to a kind of fire fighting apparatus and materials, particularly relate to a kind of bottom the conventional lift car, the setting and escape dark window and change compatible lift into fire-fighting evacuation function.

Background technology

Run into general fire alarm, people are just very alarmed, in a rush; If meet the high building fire alarm, tremble with fear especially, be stymied by.

The high building fire alarm, the lesson that stays to people is too many/and too deep.Swan restaurant, Harbin fire accident causes 10 people's death altogether, and it is the death of falling down from the building that 9 people are wherein just arranged; Foochow century Xinhua fire all, 7 philtrums just have 5 people to jump off from 10 floor windows in the room, and wherein 3 people are dead then and there; The wildfire accident of Central Hospital, Liaoyuan City has been seized 40 life and has been caused 181 people injured, and registration on same day patient in hospital always has 245 people, and the number of jumping out of the building, taking a risk to seek survival with the stubborn rope of coverlet of wherein jumping from dense smoke reaches more than hundred people unexpectedly; Big fire occurs for the Jilin ZhongBai Mall Rat, caused the tragedy of 54 people's death.During presence of fire, in more than 200 customer of market shopping, just have people more than 70 to select the escape of jumping out of the building one after another, wherein, 90% the person of jumping out of the building had been broken arms and legs with trying in any path one could without heeding which one chose, and the person that more much do not fall down from the building is dead.Such tragedy really is too numerous to enumerate, so tragic that one cannot bear to look at it, greatly distressed.

The warning mark of " banning use of elevator during fire " almost is present in each elevator next door in the whole world, and " banning use of elevator during fire " is still the current fire-fighting life-saving theory in the world.Because conventional lift does not possess the condition of security against fire, can not use as vertical evacuation instrument during fire, its major cause is as follows:

1. power supply does not have guarantee.Because during presence of fire, the fire fighter must cut off all normal operation power supplys, enables emergency source of electrical power.

2. generation chimney effect.Because elevator is in service, lift well has just lost the Smoke prevention effect, pulls out the vertical channel that cigarette puts a chimney on the stove and make the fire draw and become, and has both encouraged the pyrotechnics diffusion and has spread, and threatens people's life security again.

3. if elevator generator electric fault (or have a power failure), the evacuation personnel will be trapped within the elevator cage and can't escape danger.

And the very power supply of Fire lift can be catered to automatically, can continue operation; Have the emergency control function, promptly when presence of fire upstairs, it can accept instruction, in time returns the first floor, but no longer continues to admit the passenger, uses for the fire fighter only; It reserves an emergency evacuation outlet at car top, just in case the door-opening mechanism of elevator when malfunctioning, also can be evacuated escape (but having only the professional successfully to escape) from here.

The development of fire-fighting and rescue equipment capability of China and skyscraper is seriously unbalance at present.Existing fire-fighting system kind is single, the equipment that is used for fire-fighting fire extinguishing mainly is a fire tanker, its water spray long drive maximum capacity only is 8 floor height at present, the equipment of rescuing that is used to ascend a height mainly is the aerial ladder car, it lifts about 50 meters at present of high rescue maximum capacities, be equivalent to 15 layers of skyscraper, for higher fire of high-rise building, these fire-fighting emergent rescue outfits can only be " watchtower are heaved a sigh ".Poor, the ambient environment influence of the manoevreability of these equipments etc. is all multifactor in addition, has become that the restriction fire in high buildings is effectively puted out a fire to save life and property and the critical defect of rescue run.

In fact, real actv. escape mode or elevator are measured according to the authoritative expert, and the elevator evacuation speed has been evacuated fast more than 5 times than stair.

Since having, elevator evacuates function so efficiently, do do not why we try every possible means and utilize? in my view, the flameproof evacuation problem of high building should not because of say the so difficult confidence of dealing with problems just abandoned, Fire lift also should not be seen fantasticly like that, and the regulation of forbidding elevator may not be certain and can not change during the current fire in the whole world.I think, as long as people have really abandoned idea of leaving things to chance and fire-fighting has been caused enough attention, so, only need to increase few input and just can take precautions against great disaster hidden danger.If people are used in the cost that installs granite in elevator additional and the electricity charge of many consumptions throughout the year on the waterproof, fire prevention, anti-chimney effect of elevator cup, the above-mentioned painful tragedy in the human world will significantly reduce.

Can not be at general elevator as the global problem of the usefulness of Fire lift, we are serious analysis and solving cautiously one by one: the one, the power supply security problem, if single service, we also can design independent elevator switch before the total lock of low pressure.Can also use dual power supply, the possibility of cutting off the power supply in the fire is significantly reduced.All used dual power supply as the present elevator more than 70% in Shanghai; The 2nd, anti-chimney effect problem if we really place safety above the other things, adheres to the normal closed gate of outwards singly opening of every floor elevator cup is safeguarded usually, and anti-chimney effect just has been readily solved.But; when fire destructive greatly; just in case the power supply failed what if? what if be elevator itself out of order? even the problem that I propose has above all been solved, elevator is shut down people from pass this problem and is not fundamentally resolved, and the safety escape of high building fire alarm still leaves major hidden danger.

The 2007-11-14 of Patent Office of the People's Republic of China notification number 200,974,731 1 kinds of elevator safety windows, security window device in this utility model adopts laterally opened, does not take the car roof exceptional space when opening fully; Simultaneously, latch hook and fixed hook are the part in electrical interlocks loop, have only security window to close, latch hook and fixed hook are fully after closing, the chain loop of security window electrical safety could be connected, open security window, the chain loop of this electrical safety also disconnects thereupon ... comprise and slide guide rail (1), security window slide plate (2), slide guide rail (1) and be fixed on the car top board, security window slide plate (2) slidably is provided with and slides on the guide rail (1).

This patent has bold new intention, but safety and practicality are worth discussion.By security window slide plate and the window that slides guide rail control, in case the many crowded danger that derailing is arranged of people in the elevator; In addition, security window is opened with the descendant does not have safe and reliable path escape.
