Abstract
Description
Technical Field
[0001] The invention relates to the technical field of coal mine accident protection, in particular to a coal mine roof accident protection device. Background Art
[0002] Coal mine roof collapse mostly occurs in areas that have already been excavated and mined, namely, coal mine goafs. This is because when coal mines are excavated and mined, a large number of underground tunnels and large areas of goafs will be formed. With the increase of tunnels and the expansion of goafs, the roof of the coal seam gradually loses stability under the action of mine pressure, and the roof rock strata subsequently bend, fracture, and collapse, eventually leading to coal mine roof collapse accidents.
[0003] In coal seam roof collapse accidents, it is generally caused by the loss of support of the roof. The roof collapse on the sides and top of the tunnel is the most serious, while the bottom of the tunnel is solid and the deformation during roof collapse is small. When the roof collapses, the survivors in the rear tunnel or goaf will be trapped inside the tunnel due to the collapse of the roof in the front tunnel or goaf. Due to the lack of food, especially water, many trapped people find it difficult to hold on until the arrival of rescue supplies, which is likely to further increase casualties. Therefore, setting a protective device at the bottom of the tunnel can reduce the damage effect of the protective device and increase the survival rate of personnel. Summary of the invention

[0034] Working principle: During installation, the device is buried at the bottom of the tunnel and extended along the tunnel section by section, so that the buried guide pipe 105 is used as the input end and the intercepting ball valve 106 is used as the output end. The buried guide pipes 105 and intercepting ball valves 106 of adjacent devices are docked at one time. After installation, the intercepting ball valve 106 at the end of the guarantee position is normally closed, and the intercepting ball valves 106 at other positions are normally open. At this time, there is a buried survival maintenance docking mechanism at every other end. The installed device is docked with the power supply to ensure that the battery 309 is fully charged. At least two channels are set in this group of devices; When the roof collapses, since the bottom of the tunnel is solid, the deformation of the tunnel bottom is small, so the probability of breaking the three-way pipe 101, the buried guide pipe 105 and the intercepting ball valve 106 is relatively small. At this time, the roof collapses to form a closed space inside the tunnel; The survivors can dig out the survival maintenance docking mechanism downward in the internal space, then rotate the survival maintenance docking mechanism to make it stand up, then remove the ball valve protective cover 107 and the cabinet protective cover 316, pry the toggle block 315 to make the clamp ring 314 come out, thereby opening the cabinet door 311, and then take out the tool box 306, the survival box 307 and the medicine box 308 to distribute to the survivors. The outside world can choose whether to input water flow into the buried diversion pipe 105 to replenish the water source, or input fresh air into the interior through one of the buried diversion pipes 105, and extract air through another channel to ensure air circulation; The survivors inside need to puncture the crushing conduit 102 through the pipe-breaking cone 208. When puncturing, first close the first shut-off ball valve 106 at the rear end of the device, and then turn the hand wheel 402 forward, the hand wheel 402 drives the threaded push column 401 to rotate, and the threaded push column 401 rotates and pushes the threaded push cylinder 404 to descend, and the threaded push cylinder 404 squeezes the pipe-breaking cone 208 when it descends, and the pipe-breaking cone 208 gradually punctures the crushing conduit 102, and then reversely rotate the hand wheel 402, turn the hand wheel 402, the hand wheel 402 drives the threaded push column 401 to rotate in the opposite direction, and the threaded push column 401 rotates and pushes the threaded push cylinder 404 to rise, at this time, the water flow or air flow passes through the diversion hole 209 Enter the interior of the guide shell 501, and then open the switch valve 502 to ensure the smooth flow of fluid. When injecting water or gas, the water flow or air flow enters the hydro-turbine generator 504 through the upper conduit 503 to drive it to generate electricity, and then enters the extension hose 506 from the output pipe 505 and is finally discharged, so that the survivors can replenish water and fresh air. When pumping air, the exhaust gas enters the hydro-turbine generator 504 from the extension hose 506 through the output pipe 505, drives the hydro-turbine generator 504 to generate electricity, and then enters the guide shell 501 through the upper conduit 503 and the switch valve 502, and then enters the guide shell 501 through the diversion hole 209, and finally enters the crushing conduit 102, and is finally discharged along the three-way pipe 101 and the buried guide pipe 105.
