Abstract

The utility model discloses a coal mine underground combustion isolation and explosion suppression device. The coal mine underground combustion isolation and explosion suppression device comprises a box body, wherein the box body is a louvered folding box which is square and airtight; a plurality of outer steel plates are fixedly connected to the front outer wall and the rear outer wall of the box body respectively; an inner steel plate is further fixedly connected to the inner wall, between every two outer steel plates located on the same side, of the box body; the top end of the front wall of the box body is provided with a filling hole A, a filling hole B and an exhaust valve respectively; a plurality of mounting bolt sets are evenly distributed at the top end of the box body. The coal mine underground combustion isolation and explosion suppression device can rapidly separate roadways where explosions or fires break out from other roadways, effectively prevents high temperature fuel gas and impact waves from diffusing, enables the range affected by the explosions and the fires to be controlled and reduced, then, reduces the destructive effect of the explosions, ensures the safety of workers in the other roadways, makes the difficulty of later rescue and fire suppression work be reduced, enables the rescue to be conducted in time, and increases the survival rate of trapped workers.

Description

Under a kind of coal mine every the combustion explosion isolation device

Technical field

The utility model relates under a kind of coal mine every the combustion explosion isolation device, belongs to exploitation of mineral resources safety technics field.

Background technology

Along with the minimizing day by day of open coal mine reserves, and therefore most of ore bed can't be used opencast mode all away from earth's surface, makes the exploitation of underground coal mine become main flow.At present, little colliery quantity still accounts for the nearly 80% of mine sum, and these little colliery ubiquities safety in production basic conditions are poor, safety guarantee and the low inferior problem of the ability of preventing and fighting natural adversities, and make accident rate high, and the accident rescue difficulty are large; Wherein, the most serious fire damp blast or fire incident are difficult to control especially, if gas explosion or fire occur in a tunnel, in the situation that put out not in time and isolate, high-temperature fuel gas can diffuse to rapidly other tunnels, make the scope of damage of blast and fire further enlarge, serious threat underground labour's life security, and then cause exploding and the rescue difficulty of fire incident promotes greatly, not only workman's life security can't guarantee, and difficulty and the danger of the fire suppression work after the rescue end are also high.

The utility model content

The purpose of this utility model is: provide under a kind of coal mine every the combustion explosion isolation device, with after solving coal mine and issuing living gas explosion, high-temperature fuel gas spreads rapidly, and makes the problem that the blast scope of damage is wide, the rescue difficulty reaches greatly fire suppression work difficulty.

The technical solution of the utility model:

Under a kind of coal mine every the combustion explosion isolation device, comprise casing, described casing is prismatic sealed louvered folding carton, on the front outer wall of casing and rear outer wall, is connected with some outer steel plates, and the cabinet wall be between every two blocks of outer steel plates of the same side also is connected with interior steel plate; Casing antetheca top offers respectively filler opening A, filler opening B and outlet valve; The casing top is evenly equipped with some groups of erection bolts.

On the antetheca of described casing and rear wall, between affixed some outer steel plate and interior steel plate, fastening steel cable also is installed.

The syndeton of described outer steel plate, interior steel plate and casing can be bolt or U-shaped card.

Described fastening steel cable two ends are connected with the syndeton end of outer steel plate or interior steel plate.

The material of described casing is non-flammable adhesive tape.

The width of described outer steel plate is greater than the width of casing.

Described erection bolt has four groups at least.

Distance between every group of erection bolt is 30～50cm.

The height of described outer steel plate and interior steel plate is 20～30cm.

The beneficial effects of the utility model:

Compared with prior art, under the coal mine that the utility model provides every the combustion explosion isolation device, adopt the expansion of louvered folding carton to play the effect every the combustion flame proof, it can play rapidly the effect every the combustion flame proof, the tunnel of blast and other tunnel are separated, effectively prevented the diffusion of high-temperature fuel gas and shock wave, make explosive range be controlled and dwindle, and then reduced the destructiveness of blast, guarantee the safety of staff in other tunnel, make the difficulty of later stage rescue and fire suppression work descend, can rescue in time, promote stranded staff's survival rate.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the front view of Fig. 1;

Fig. 3 is A-A sectional view in Fig. 2;

In figure: 1-casing, 2-erection bolt, the outer steel plate of 3-, 4-outer bolt, 5-inner bolt, 6-filler opening A, 7-filler opening B, steel plate in 8-outlet valve, 9-, the fastening steel cable of 10-.

The specific embodiment

Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but that desired protection domain is not limited to is described;

As shown in Figure 1,2 and 3, under the coal mine that the utility model provides every the combustion explosion isolation device, comprise casing 1, described casing 1 is prismatic sealed louvered folding carton, on the front outer wall of casing 1 and rear outer wall, be connected with some outer steel plates 3, casing 1 inwall be between every two blocks of outer steel plates 3 of the same side also is connected with interior steel plate 9; Casing 1 antetheca top offers respectively filler opening A6, filler opening B7 and outlet valve 8; Casing 1 top is evenly equipped with some groups of erection bolts 2.

For the problem of rocking that prevents that bottom of the present utility model is prone to when descending, between affixed some outer steel plate 3 and interior steel plate 9, fastening steel cable 10 also is installed on the antetheca of described casing 1 and rear wall.

Described outer steel plate 3, interior steel plate 9 can be bolt or U-shaped card with the syndeton of casing 1.

Described fastening steel cable 10 two ends are connected with the syndeton end of outer steel plate 3 or interior steel plate 9, and it can play the effect of firm connection, and then strengthen the anti-shake performance.

Of the present utility model every the combustion explosion insulation performance in order further to promote, the material of described casing 1 is non-flammable adhesive tape.
