Abstract

The invention discloses a passage and tunnel obstruction device in a fire disaster. The device consists of an automatic roller shutter door, a controller, a water spray head and a sensor, wherein the sensor is in communication connection with the controller; the automatic roller shutter door and the water spray head are controlled by the controller; water spray direction of the water spray head is aligned with a door curtain which is formed by stretching the automatic roller shutter door; and the door curtain is made of a flexible material. The device has the beneficial technical effects that: spread of smoke and fire can be effectively obstructed and survivors can conveniently get through; and the device has a simple structure and is low in cost.

Description

Passage, tunnel partition apparatus in the fire

Technical field

The present invention relates to a kind of fire prevention, relate in particular to passage in a kind of fire, tunnel partition apparatus.

Background technology

Existing fire disaster emergency device adopts the spray equipment sprinkling fire or adopts fireproof door blocking-up fire spreading, but, there is wretched insufficiency in these two kinds of emergency processing modes, at first, adopt the spray equipment sprinkling fire to be difficult to flue gas is effectively suppressed, the result shows according to statistics, and the dead person in the fire more than 85% causes death owing to having sucked flue dust and toxic gas stupor back; And when adopting fireproof door blocking-up fire spreading, in a single day fireproof door puts down, and personnel can't pass through from fireproof door, have blocked best-effort path.

Summary of the invention

At deficiency of the prior art, the present invention proposes passage in a kind of fire, tunnel partition apparatus, its structure is: it is made up of automatic curtain door, controller, fountain head and sensor; Sensor and controller communicate to connect, and automatic curtain door and fountain head are controlled by controller, and the water spraying direction of fountain head is aimed at the door curtain after the automatic curtain door launches; Door curtain adopts flexible material to make.

Described sensor adopt among smoke detector, temperature detection device, the manual start device three a kind of, two or three.

Door curtain is rearranged in turn by many canvas strips, and adjacent two canvas strips flanging are arranged.

The flanging width of adjacent two canvas strips is greater than 5cm.

The door curtain both sides respectively are provided with a plurality of fountain heads, and the sputter scope of the water of fountain head ejection covers whole door curtain.

In passage or tunnel, whenever keep at a certain distance away passage in the fire, tunnel partition apparatus just are set.

Useful technique effect of the present invention is: can block spreading and allowing the survivor pass through easily of the smog and the intensity of a fire effectively, apparatus structure is simple, with low cost.

The specific embodiment

Structure of the present invention is: it is made up of automatic curtain door 1, controller 2, fountain head 3 and sensor 4; Sensor 4 communicates to connect with controller 2, and automatic curtain door 1 and fountain head 3 are controlled by controller 2, and the water spraying direction of fountain head 3 is aimed at the door curtain 1-1 after automatic curtain door 1 launches; Door curtain 1-1 adopts flexible material to make.

Its course of work is: automatic curtain door 1 is arranged on the top in passage or tunnel, and during the no condition of a fire, automatic curtain door 1 with door curtain 1-1 winding up together; The situation of change of sensor 4 real-time surrounding being monitored, and Monitoring Data is sent to controller 2, when the input signal of sensor 4 reaches preset threshold, the condition of a fire promptly appears, the automatic curtain door 1 of controller 2 control sensors 4 both sides puts down door curtain 1-1, control fountain head 3 simultaneously and begin water spray, the water of fountain head 3 ejections is splashed to door curtain 1-1 and upward and with door curtain 1-1 soaks, door curtain 1-1 after soaking can't be lighted, stoped spreading of the intensity of a fire, also increased simultaneously the air-tightness of door curtain 1-1, smog can't pass, and has stoped spreading of smog, has guaranteed that non-ignition point place is not encroached on by smog, also blocked simultaneously the quick circulation of air, suppressed the facilitating effects of air the intensity of a fire; When the survivor arrived door curtain 1-1, because door curtain 1-1 adopts flexible material to make, the survivor can raise door curtain 1-1 and pass through, promptly guaranteed the unimpeded of best-effort path, the drawback of having avoided fireproof door that the path is blocked fully can stop smoke spread personnel by the back auto-closing again.

Described sensor 4 can adopt smoke detector, temperature detection device or manual start device, also can adopt any two kinds of combinations in aforementioned three kinds of devices, also can adopt simultaneously by three kinds of devices.Wherein, manual start device also can link with fire alarm equipment.

Because canvas material is after water spray is saturated, can satisfy the requirement of not firing under the high temperature, and the canvas ageing resistace is strong, cheap, door curtain 1-1 can adopt canvas to make: door curtain 1-1 is rearranged in turn by many canvas strips 1-1-1, and the end of each bar canvas strips 1-1-1 is connected with the winding up device of automatic curtain door 1, and the other end is sagging naturally, in order to guarantee air-tightness, adjacent two canvas strips 1-1-1 flanging are arranged.The flanging width of adjacent two canvas strips 1-1-1 is greater than 5cm.

In order to make door curtain 1-1 reach the saturated state of suction fast, in door curtain 1-1 both sides a plurality of fountain heads 3 are set respectively, the sputter scope of the water of fountain head 3 ejections covers whole door curtain 1-1.

In passage or tunnel, whenever keep at a certain distance away passage in the fire, tunnel partition apparatus just are set, after the condition of a fire takes place, passage, tunnel partition apparatus are worked simultaneously in the fire of regional both sides on fire, the little space that passage or tunnel are divided into a sealing and can the assurance personnel pass through, having blocked outside air is communicated with the direct of ignition point, avoided often occurring in the fire, after opening passway for escaping, tunnel, extraneous air is entered unbridledly, encourage the problem that the intensity of a fire further enlarges.
