The soft passage has a simple structure, can be carried conveniently, and can provide reliable tools for rescue.

Description

A kind of soft passage

Technical field

The utility model relates to a kind of soft pipeline of air filling type, can set up the rescue passage of a drying, safety after mine disaster generation water leak accident at " U " shape mine two ends of immersion.

Background technology

After the mine disaster water leak accident takes place, generally can carry out the detection of trapped personnel earlier, carry out corresponding rescue work again, and concerning have as the tunnel of " U " shape, mid portion immersion water channel might occur, and two is in the situation of the water surface.For the trapped personnel that has no the experience of diving under water, can't pass through the immersion water channel in this case.

Summary of the invention

The soft passage of air filling type of rescue passage is set up at a kind of " U " shape mine two ends that are used in immersion at above-mentioned situation of the utility model design.

A kind of soft passage, comprise the tubular pipeline that watertight passage internal layer forms, it is characterized in that, wear-resisting passage skin is arranged outside watertight passage internal layer, a transfer chamber is respectively arranged in the two ends of pipeline, and respectively there is a transition hatch at the transfer chamber two ends, and a transition hatch is connected with the middle part of pipeline, another transition hatch leads to outside, on watertight passage internal layer outside transfer chamber and the wear-resisting passage skin safety valve and charge valve is installed.

Between watertight passage internal layer and wear-resisting passage skin, the filling interlayer is arranged.

At the two ends of pipeline the abutted flange ring is installed.

The utility model is simple in structure, and is easy to carry, for rescue provides reliable instrument.

The specific embodiment

A kind of soft passage, comprise the tubular pipeline 10 that watertight passage internal layer 6 forms, it is characterized in that, wear-resisting passage skin 5 is arranged outside watertight passage internal layer 6, a transfer chamber 11 is respectively arranged in the two ends of pipeline 10, and transfer chamber 11 two ends respectively have 1, one transition hatch 1 of a transition hatch to be connected with the middle part of pipeline 10, another transition hatch 1 leads to outside, on watertight passage internal layer 6 outside transfer chamber 11 and the wear-resisting passage skin 5 safety valve 3 and charge valve 4 is installed.

The interlayer 7 of filling is arranged between watertight passage internal layer 6 and wear-resisting passage skin 5.

At the two ends of pipeline 10 abutted flange ring 2 is installed.

The air filling type pipeline of rescue passage is set up at a kind of " U " shape mine two ends that are used in immersion of the utility model design; this passage is soft double-skin duct; the abrasionproof topping that its skin interweaves and constitutes for high-intensity fiber, internal layer is the waterproofing and airtight layer of rubber and plastic adhesion.

Soft rescue passage two ends have a transfer chamber respectively, be used for the changeover portion that personnel enter pipeline, on the transfer chamber of its middle outlet one end charge valve and safety valve are housed respectively, are used for passage is inflated, and guarantee that the interior gas pressure of passage is in certain safe range.

Two terminations of escape and rescue trunk, soft tunnel transition hatch is separately installed with a flange ring, can realize linking to each other in twos of this soft tunnel escape and rescue trunk by this flange ring on the one hand; Can directly dock with the mine disaster rescue station on the other hand, trapped personnel is directly escaped by passage from the mine disaster rescue station.

For the ease of transportation and mobile, when storing, soft mine rescue passage wants the emptying internal gas, be kept in storage bin or the reservoir bag after folding.

As shown in Figure 1, the utility model is made up of transition hatch 1, abutted flange ring 2, safety valve 3, charge valve 4, wear-resisting passage skin 5, watertight passage internal layer 6, filling interlayer 7, and wherein wear-resisting passage skin 5, watertight passage internal layer 6, filling interlayer 7 have been formed the main body of soft tunnel escape and rescue trunk.Wear-resisting passage skin 5 plays protection, watertight effect at outermost layer, and watertight passage internal layer 6 mainly plays the watertight effect at innermost layer, fills interlayer 7 between wear-resisting passage skin 5, watertight passage internal layer 6, is cushion coat.

Filling interlayer 7 can not want sometimes yet.

Abutted flange ring 2 is installed in the two ends of soft tunnel escape and rescue trunk respectively, can carry out the watertight butt joint.

There are two transition hatch 1 each termination of escape and rescue trunk, soft tunnel, and one of them is fixed on the abutted flange ring 2 inner channel mouths, and another is fixed on the watertight passage internal layer 6 of flange ring certain distance, forms a transfer chamber between two transition hatch 1;

Transition hatch 1 is fixing in escape and rescue trunk two ends, soft tunnel symmetry.

Be depicted as the state that soft tunnel escape and rescue trunk is inflated, after trapped personnel enters into transfer chamber, seal corresponding transition hatch 1, begin to inflate by charge valve 4.

Figure 3 shows that the state of soft tunnel escape and rescue trunk after inflating expanded, trapped personnel can move to the other end from an end by the passage after launching, and realizes rescue.
