In the prior art, in the time that needs are put out a fire, be all generally to make water as firing-fighting medium.For example notification number is CN201200742, name is called a kind of utility model patent of fire-fighting system for escalator, this fire-fighting system comprises multiple subsystems that arrange separately along escalator length direction, and described subsystem comprises water inlet pipe, is connected to the fire-fighting spraying head on described water inlet pipe.This fire-fighting system has to escalator step the effect of imitateing preferably, but it is not also suitable for staircase and girder, the fire causing for electric short circuit and greasy dirt, water is helpless, can cause on the contrary truss charged and strengthen the intensity of a fire, cannot ensure passenger's safety, and after fire extinguishing, truss internal water accumulation be difficult to cleaning, ponding easily causes the corrosion of some objects in truss, the service life of greatly reducing staircase.
Therefore, researching and developing a kind of escalator that can be applicable to especially can better protect the extinguishing device of staircase and girder extremely urgent.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of a kind of escalator extinguishing device being installed in staircase and girder is provided, to solve the safety issue of staircase in the inner breaking out of fire of truss, make staircase operation safer, can accomplish to put out in time rapidly flare at the initial stage on fire, ensure passenger safety.
For achieving the above object, the utility model is achieved by the following technical programs:
A kind of escalator extinguishing device described in the utility model, comprises staircase controller, also comprises:
Be arranged on respectively some fire detectors that staircase and girder top driving station, tilted section of truss and bottom turn to station; Be arranged on respectively the detection of gas flow rate feedback transducer that top driving station and bottom turn to station; Be fixed on the high-pressure carbon dioxide transfer pipeline that staircase is fixed on a side in truss, with the external carbon dioxide storage container being communicated with high-pressure carbon dioxide transfer pipeline, described high-pressure carbon dioxide transfer pipeline is provided with pipeline electromagnetic valve and multiple nozzle, on described carbon dioxide storage container, container magnetic valve is installed; Described fire detector, detection of gas flow rate feedback transducer, pipeline electromagnetic valve, container magnetic valve are all connected by cable with staircase controller.
As the further improvement of above-mentioned technology, described cable periphery is enclosed with high flame retardant nylon grade nylon hose.
In the utility model, described container magnetic valve or/and pipeline electromagnetic valve powered by safe voltage direct current 24V.
In the utility model, described fire detector is compound smoke-temperature sensing fire detector.
In the utility model, the upper descending stair head of described staircase is provided with the staircase display for showing.
Compared with prior art, the beneficial effects of the utility model are:
(1) escalator extinguishing device described in the utility model adopts carbon dioxide as firing-fighting medium, and fire extinguishing scope covers the inner space of whole staircase and girder, and fire extinguishing is directly simple, wide material sources, produce easy, cheap; In addition, also can put out the burning things which may cause a fire disaster that in staircase, different reasons cause, the situation of having avoided the fire that causes because of leakage circuit or greasy dirt can not water to put out, and there is no firing-fighting medium residue, safety and environmental protection after fire extinguishing.
(2) the utility model is sent to staircase controller by some fire detectors in time by fire information, thereby can accomplish just can find that at the initial stage on fire fire puts out a fire, and guarantees personal safety and property safety.
(3) the utility model also carries out good information feedback by detection of gas flow rate feedback transducer, make in the time that fire occurs, and high-pressure carbon dioxide transfer pipeline unimpeded, guaranteeing that fire extinguishing is puted out a fire to save life and property carries out accurately and timely.
