Abstract
The utility model discloses an emergency ventilation device for a fire shelter in a tall building. The emergency ventilation device comprises a ventilation pipe and a pipe fan, and is characterized in that the ventilation pipe is a multi-stage telescopic pipe and is made of high temperature resistant fire-proof material; the telescopic ventilation pipe passes through a hole on the lower part of the outer wall of the shelter to extend to a position which is at least 15m away from the outer wall; the surface of the telescopic ventilation pipe outside the wall is coated with striking fire-proof reflective film; a colorful flying object which is made of fire-proof reflecting material is hung in at least one of the joints of the telescopic ventilation pipe; and the pipe fan is powered by emergency backup power. The emergency ventilation device for the fire shelter in the tall building has the advantages that natural air is continuously input to the sealed shelter from a relatively far space through the telescopic ventilation pipe, so that the quality of life of a refugee is greatly enforced, and precious time is gained for the rescuing; furthermore, due to the reflective telescopic ventilation pipe extending out of the wall and the hung colorful flying object, a rescuer can find the refugee more easily to implement rescue.
Description
Technical field
The utility model belongs to the fire in high buildings room life support equipment of taking refuge, and specifically, relates to a kind of fire in high buildings room emergency ventilation device of taking refuge.
Background technology
The high building resident when running into fire of high-rise building, two kinds nothing more than of escape methods: 1, when during Initial Stage of Fire or the intensity of a fire are not too violent, cover mouth and nose with wet towel, escape to bottom or roof from fire-fighting stairway rapidly; When there's nowhere to run if 2 escape routes are blocked by big fire, should hide immediately into the room that closing door is arranged, and close rapidly door, with things such as wet towels that door crack filler strip is tight, wait for rescue.But the resident in the room of hiding in the reality often waits to arrive less than rescue and just poisons because suck poisonous gas, perhaps anoxia asphyxia causes simultaneously people to take to open door and rushes in the corridor that is full of flame and toxic smoke or the behavior of simply taking a risk even being equivalent to commit suiside from extremes such as window jump down.The main cause that this bad final result occurs is to lack enough life-support systems in our room, particularly lack wait for rescue before required natural air, and do not known as the fear of waiting for death by the people in the shelter hiding.
Summary of the invention
The purpose of this utility model is the problem that exists for prior art, and a kind of fire in high buildings room emergency ventilation device of taking refuge is provided, and its reasonable in design is remarkably productive, with important life support equipment and the externally emergency sign in the room of taking refuge as fire in high buildings.
The purpose of this utility model is achieved by the following technical solution: a kind of fire in high buildings room emergency ventilation device of taking refuge, comprise ventilation duct and pipeline fan, and it is characterized in that ventilation duct is the multi-stage expansion pipe.
Preferably, described flexible ventilation duct is positioned at the room of taking refuge, the inside and outside porthole of a communication chamber is established in the described exterior wall bottom, room of taking refuge, be suitable for flexible ventilation duct turnover, described porthole is shut at ordinary times, can open fast when needing, described porthole side in the room is other to be provided with Elastic supporting roller, is convenient to flexible ventilation duct and stretches rapidly and shrink.
Preferably, after described flexible ventilation duct elongates, its length that is positioned at the outer part of wall is no less than 15 meters, wherein suspension ring are equipped with in the junction between second section and the 3rd joint or the 3rd joint and the 4th joint, wall is provided with another suspension ring outward directly over the described porthole, be connected with rope between two suspension ring, described flexible ventilation duct, suspension ring and rope are all made by resistant to elevated temperatures fire proofing material.
Preferably, the inside, junction of described flexible ventilation duct is provided with the refractory seals pad, and it is indoor to prevent that toxic gas is inhaled into.
Preferably, the described outer flexible ventilation duct surface of wall that is positioned at scribbles eye-catching fire prevention reflective membrane, and the junction of at least one flexible ventilation duct hangs with the bright thing that waves of being made by the fire prevention reflectorized material.
Preferably, described pipeline fan is contained in flexible ventilation duct and is positioned at end in the room of taking refuge, and is powered by emergency standby power.
Preferably, the end of described flexible ventilation duct can be communicated to other room by external fire-resistant ventilation duct.
The utility model has following advantage and good effect: constantly input natural air from space far away by flexible ventilation duct in the airtight room of taking refuge, and make indoor air pressure be malleation, effectively stop the intrusion of toxic gas, greatly strengthened refugee's life quality, for the arrival of rescuing tries to gain time precious to one; Secondly, the bright-coloured thing that waves that stretches out the outer reflective flexible ventilation duct of wall and suspension can make that the rescuer is easier to be found us and sue and labour.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the take refuge embodiment of room emergency ventilation device of a kind of fire in high buildings, comprise flexible ventilation duct 2, pipeline fan 3, carrying roller 6, described flexible ventilation duct 2 is positioned at the room 1 of taking refuge, the take refuge exterior wall bottom in room 1 is provided with porthole 8, flexible ventilation duct 2 extends to outside the wall by porthole 8, wherein the second and the 3rd suspension ring that save the ventilation duct junction link to each other by rope 5 with the suspension ring directly over the porthole 8 are middle, and the 3rd and the 4th joint ventilation duct junction hangs with the reflective thing 7 that waves, described flexible ventilation duct 2, the reflective thing 7 that waves, the suspension ring at rope 5 and rope 5 two ends are all made by resistant to elevated temperatures fire proofing material.
Described pipeline fan 3 is contained in flexible ventilation duct 2 and is positioned at end in the room of taking refuge, by emergency standby power 4 power supplies.
Open porthole 8 during use, under the help of carrying roller 6, rapidly flexible ventilation duct 2 is stretched to long status, at this moment the reflective thing 7 that waves automatically scatters and waves, and rope 5 just is tensioned state, and play the traction supporting role to stretching out the outer flexible ventilation duct of wall, and then give pipeline fan 3 energisings, natural air at a distance just is input in the room of taking refuge endlessly, used for the refugee, the external rescue person also sees our emergency sign easily simultaneously.
The above only is preferred embodiment of the present utility model, be not that structure of the present utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
