[0001] The invention relates to the field of underground coal mine protection devices, and in particular to a water seepage and burst prevention buffer device. Background Art

[0002] At present, the main anti-burst device used in coal mines is the anti-burst air door. Once built, the anti-burst air door is a permanent air door. The anti-burst air door is on the air inlet side of the excavation face, including two sets of positive and negative air doors. Once encountering a blast or water seepage, the two sets of air doors will automatically close due to the thrust of the shock wave, completely isolating the affected area. As the excavation face extends, the distance of the tunnel increases, and the anti-burst air door is far away and cannot respond quickly, reducing the safety of protection. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 The illustrated anti-water penetration and anti-burst buffer device comprises: a fixing mechanism 1, a buffer door curtain 2 and a trigger mechanism 3. The fixing mechanism 1 is fixed at the top of the tunnel, the buffer door curtain 2 is installed on the fixing mechanism 1, the buffer door curtain 2 is rolled from the bottom to the top and fixed by the fixing mechanism 1, the trigger mechanism 3 is connected to the fixing mechanism 1, and the trigger mechanism 3 is fixed at the top of the tunnel; the buffer door curtain 2 comprises two groups of front and rear staggered multiple curtain bodies, each curtain body is provided with a pocket 21 on the lower part, and the length of each curtain body is higher than the height of the tunnel, so that the pocket can be dragged on the ground. The fixing mechanism is used to fix the buffer door curtain, and there are various structures of the fixing mechanism; the trigger mechanism is to cause the fixing mechanism to be separated from the trigger mechanism under the action of external force, so that the buffer door curtain falls by its own weight, blocking the tunnel to form a flexible protection. There is a pocket on each curtain body of the buffer door curtain to form a protective buffer.

[0023] like Figure 1 As shown, the fixing mechanism 1 includes a mounting rod 11, a side baffle 12 and a traction rope 13. The mounting rod 11 is fixed to the top of the tunnel, the side baffle 12 is fixed to one side of the mounting rod, and the traction rope 13 is fixed to the bottom end of the side baffle 21; the buffer door curtain is fixed to the mounting rod. An axial hole is provided at the bottom end of each curtain body, and a rotating shaft is provided in the axial hole of any group of curtain bodies to facilitate the rolling up of the curtain body. After the curtain body is rolled up, it is close to the side baffle, and the traction rope is fixed upward to the trigger mechanism through the bottom end of the rolled-up curtain body to fix the rolled-up curtain body. The traction rope is detached from the trigger mechanism to release the fixation of the curtain body. The fixing method of the fixing mechanism is simple, and it is easy to detach the traction rope from the trigger mechanism, thereby increasing the stability of use. The side baffle can be an arc-shaped baffle or a vertical baffle.

[0024] The multiple curtain bodies include two groups of curtain bodies staggered front and back to increase the tightness of protection. The lower part of each curtain body is provided with more than one pocket, and the multiple pockets are closely arranged in sequence along the long side direction of the curtain body. Each curtain body is provided with multiple pockets, some of which are dragged on the ground, and some of which are vertical with the curtain body. When water seepage occurs, the mixture of water and coal slime flows into the pockets dragged on the ground, and the mixture of sprayed water and coal slime directly splashes on the curtain body or the pockets on the curtain body, and flows into the pockets standing on the curtain body, and accumulates layer by layer to form a natural barrier, which slows down the flow rate and flow of water, prolongs the escape time, and delays the disaster area.

[0025] like Figure 1 As shown, the trigger mechanism 3 includes a lock shell 31, a lock body 32 and a touch plate 33. The lock shell 31 is a cylindrical shell with a notch on the side. A connecting column 34 is arranged on the outer side of the lock shell 31. The lock core 321 of the lock body is located inside the lock shell, and the lock rod 322 is located outside the lock shell. The lock body 32 can rotate on the lock shell, and a return spring 35 is arranged between the lock rod and the lock shell. The touch plate 36 is fixed on the lock rod. The lock core 321 is arranged as a ring with a notch; the notch of the lock core corresponds to the notch of the lock shell. A movable groove is arranged at the connection between the bottom end and the side of the lock shell, and the lock body passes through the movable groove and rotates in the movable groove.

[0026] The method of use is as follows: the rope end of the traction rope of the fixing mechanism is hung on the lock core of the lock body through the notch of the lock shell, and the lock rod is connected to the lock shell by a reset spring. The lock rod is stably connected in the untriggered state; under the action of the shock wave or the jet of water, the touch plate drives the lock core connected to the traction rope to rotate in the direction away from the notch, and the traction rope is separated from the hook under the action of the edge of the notch of the lock shell to complete the triggering; the lock rod returns to its original state under the action of the reset spring. The trigger mechanism triggers the fixing mechanism, the traction rope falls, the buffer door curtain is separated from the fixing mechanism, and the buffer door curtain opens under the action of gravity to block the lane. When water seepage occurs, the mixture of water and coal slime flows into the pocket dragged on the ground, and the mixture of sprayed water and coal slime directly splashes on the curtain body or the pocket on the curtain body, and flows into the pocket standing on the curtain body, and accumulates layer by layer to form a natural barrier. When anti-burst occurs, the shock wave or wind flow acts on the trigger mechanism, the buffer door curtain falls by gravity, and the air flow acts on the curtain body to form a layer of buffer in the pocket. The anti-water penetration and anti-bulging buffer device of the present invention has a protective effect on both water penetration andbulging.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
