Abstract
The invention relates to an underground laneway gas explosion prohibitor, which is characterized in that an extinguishing agent vessel is provided with a feed opening, a safety valve, a pressure gauge and an extinguishing agent draining outlet; the extinguishing agent vessel is provided with three rows of outlets, wherein one row of the outlets are shock wave pressure switching outlets, the other row of the outlets are high temperature flame switching outlets, and another row of the outlets are manual operation switching outlets; and the three rows of the outlets are connected with an extinguishing agent main pipe which is connected with a pipe net and a spray head. When gas explosion happens underground, due to the action of shock wave pressure or high temperature flames, a switch on the extinguishing agent vessel is switched on, and the extinguishing agent in the extinguishing agent vessel is sprayed into the whole laneway instantly so as to play a role in blocking off the explosion flames.
Description
Technical field: down-hole tunnel gas explosion blocking device belongs to the safety of coal mines technical field, is specially adapted to colliery prevention and control gas explosion.
Background technology: by overall understanding, the most frequently used datonation-inhibition technology of roadway is a tank flame proof canopy at present, it is also very advanced that a kind of rock dust in South Africa sprays blocking-up blast equipment in addition, but it is inhomogeneous when the water of tank flame proof canopy spills, section cuts off flame entirely, and rock dust when depositing in the down-hole easy moisture absorption become piece, can not form dust cloud during sprinkling, can't block flame.The objective of the invention is at the problems referred to above, innovation and creation down-hole tunnel gas explosion blocking device.
Summary of the invention: down-hole tunnel gas explosion blocking device is characterized in that being equipped with on the foamite container charging aperture, safety valve, pressure meter and extinguishing chemical sewage draining exit, have three to wade out mouth on the foamite container, be the outlet of shock wave pressure switch one time, another time is the outlet of thermal-flame switch, also having one time is that hand switch exports, three wade out mouth links to each other with the extinguishing chemical person in charge side by side, the person in charge is connected with shower nozzle with pipe network, when gas explosion takes place in the down-hole, because the effect of shock wave pressure or thermal-flame is with the switch opens on the foamite container, moment is sprayed at the extinguishing chemical in the foamite container in the whole tunnel, thereby plays the effect of blocking-up explosive flame.
Down-hole tunnel gas explosion blocking device compared with prior art has the following advantages:
1, can repeat repeatedly to use the service year limit for length.
2, can block the flame propagation of explosion time, dwindle the accident scope.
3, can improve the ability of mine reply disaster.

The specific embodiment: existing is the example explanation with the accompanying drawing: down-hole tunnel gas explosion blocking device is left in the chamber in tunnel, and pipe network connected arrange, it is characterized in that: on the foamite container (1) of band pressure charging aperture (2) is installed, safety valve (3), pressure meter (4), sewage draining exit (5) and gas pressurized mouth (6), foamite container has three to wade out mouth on (1), one wades out mouthful to the shock wave pressure switch and exports (7), another time is thermal-flame switch outlet (8), also having one time is that hand switch exports (9), three wade out mouth links to each other with the person in charge (10) side by side, being responsible for (10) links to each other with shower nozzle (11) with pipe network, three other ends that wade out mouth all go deep into the bottom in the foamite container (1), the above high pressure noble gas bottle (12) of gas pressurized mouth (6) on the foamite container (1) and 10Mpa links to each other, when the pressure on the foamite container with pressure (1) is lower than 1.0Mpa, high pressure noble gas bottle (12) is opened automatically, pressurize to foamite container (1) by gas pressurized mouth (6), till the extinguishing chemical in foamite container (1) has sprayed.
Claims (2)
1, the feature of down-hole tunnel gas explosion blocking device be the band pressure foamite container on charging aperture, safety valve, pressure meter, sewage draining exit and gas pressurized mouth are installed, have three to wade out mouth on the foamite container, one wades out mouthful to the shock wave pressure switch and exports, another time is the outlet of thermal-flame switch, also having one time is that hand switch exports, three wade out mouth side by side be responsible for link to each other, the person in charge links to each other with shower nozzle with pipe network, three other ends that wade out mouth all go deep into the interior bottom of foamite container.
2, according to the above the feature of down-hole tunnel gas explosion blocking device of claim be: the gas pressurized mouth on the foamite container links to each other with high pressure noble gas bottle more than the 10Mpa, when the pressure on the foamite container with pressure is lower than 1.0Mpa, high pressure noble gas bottle is opened automatically, pressurize to foamite container by the gas pressurized mouth, till the extinguishing chemical in foamite container has sprayed.
