Abstract
The utility model discloses a coal mine fire prevention separating device, which comprises an air bag frame, a fire prevention partition and an inflator pump. The shape of the air bag frame is identical with that of a coal mine roadway; the air bag frame is arranged on the peripheral edge of the fire prevention partition and communicated with a gas outlet of the inflator pump; the whole structure is unfolded by filling gas into the air bag frame; and the roadway can be sealed by closely attaching the air bag frame with a roadway wall. Moreover, the whole device is lighter and convenient to be contained and carried, can be rapidly sent to an accident scene and rapidly installed, rapidly seals the roadway, and performs the function of extinguishing fire by enabling firing positions to be oxygen-deficient.
Description
Technical field
The utility model relates to a kind of partition apparatus, particularly a kind of mine fire prevention partition apparatus.
Background technology
In a single day occur fire in the colliery when the goaf, what harm was maximum is the blast that causes mist in it.Know that by the mist explosion triangle oxygen content is lower than at 12% o'clock in the mist just the possibility that reduces to explode.But the boundary of mist blast not only depends on this gas shared percentage in air, also is decided by the temperature and the air pressure of mist partially.Increasing of temperature and air pressure enlarges this boundary, otherwise dwindles.If mist is heated to 300 ℃, oxygen content is just can blast in 9% o'clock.Thereby domestic studies show that, the critical content of oxygen is controlled at 5% almost can prevents any blast when following, otherwise blast also might take place.And the content of oxygen is lower than the blast of 10% o'clock mist significant reduction is arranged.After the colliery catches fire now, generally adopt the splice sealing, after oxygen depletes in the wait enclosed area, allow fire extinguish naturally.But longer during the engineering cost of this enclosing tunnel, and wait in the enclosed area that burning things which may cause a fire disaster extinguishes naturally need be for a long time.
Coal mine roadway is relatively narrow, if can just can fast the tunnel sealed from the nearer place of burning things which may cause a fire disaster at the initial stage on fire, and pours into inert gas or water filling simultaneously in the tunnel, can realize the purpose of quick extinguishing.
Therefore, need a kind of fire prevention partition apparatus, can also in the tunnel, pour into fire-suppressant gas or extinguishing chemical simultaneously rapidly with the tunnel sealing.
The utility model content
In view of this, the utility model provides a kind of fire prevention partition apparatus, can also pour into fire-suppressant gas or extinguishing chemical simultaneously in the tunnel rapidly with the tunnel sealing.
Mine fire prevention partition apparatus of the present utility model comprises that air bag frame, fire prevention cut off and inflator pump; Described air bag frame is arranged at fire prevention and cuts off the edge, and is communicated with the inflator pump gas outlet.
Further, described fire prevention partition is provided with fire extinguishing hole, the embedded plough groove type connector that is provided with in described fire extinguishing hole;
Further, described fire prevention partition is provided with lengthways of rod;
Further, described fire prevention is provided with transparent windows on cutting off.
The beneficial effects of the utility model: by the gas of in the air bag frame, annotating, total is propped up, allow air bag frame edge and tunnel body of wall fit tightly, can seal the tunnel, and whole device is lighter, is convenient to take in and carry, can deliver to the scene of the accident fast, Fast Installation seals the tunnel rapidly, makes the fire position anoxic and plays the effect of fire extinguishing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structure side view of the present utility model.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a structure side view of the present utility model; As shown in the figure: the mine fire prevention partition apparatus of present embodiment, comprise air bag frame 1, fire prevention partition 2 and inflator pump 3, air bag frame 1 and fire prevention cut off 2 and make by refractory material, can be high temperature resistant, air bag frame 1 can be made as rectangle, trapezoidal or arcuate structure according to the shape of mine laneway, and air bag frame 1 is arranged at fire prevention and cuts off 2 edges, designs for integral type with fire prevention partition 2, inflator pump is communicated with the air bag frame, the gas of can annotating fast in the air bag frame.
As further improvement of this embodiment, described fire prevention cuts off 2 and is provided with fire extinguishing hole 4, the described fire extinguishing hole 4 embedded plough groove type connectors that are provided with, and the plough groove type connector is a standard Fire Fighting Company joint, can be connected with fire protection pipeline fast, puts out a fire.
As further improvement of this embodiment, fire prevention cuts off 2 and is provided with lengthways of rod 5; Lengthways of rod 5 cuts off 2 for detachable fixedlying connected with fire prevention, and is for convenience detach, after inflation, lengthways of rod 5 is fixed on fire prevention cuts off on 2, can play a supportive role.
As further improvement of this embodiment, on the fire prevention partition 2 transparent windows 6 is set, the height of transparent windows is about about 1.6m, is convenient to the operating personnel and observes other end situation.
The utility model in use by the gas of annotating in air bag, props up total, allow cell edges and tunnel body of wall fit tightly, can seal the tunnel, can connect the fire extinguishing hole to confined space perfusion fire-suppressant gas or extinguishing chemical by fire protection pipeline simultaneously, improve fire-fighting efficiency.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
