[0002] During the coal mining process, since the coal seams contain a large amount of gas, the coal seams will release gas, which is easy to cause sudden accidents. In modern coal mine production, measures to prevent coal seams from being mined will be taken to eliminate the danger of sudden coal seams. The most commonly used measure is to drill holes in the original coal body and use sealers to extract gas to reduce sudden coal accidents.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A gas extraction hole sealer with a detection structure, such as Figure 1-5 As shown, the main body assembly 100 includes a sleeve 110, the inner wall of the sleeve 110 is fixedly connected with six sets of fixing rings 120, the inner walls of the six sets of fixing rings 120 are fixedly connected with an air extraction pipe 130, a sealing assembly 200 is arranged inside the air extraction pipe 130, and a detection assembly 300 is arranged on the side of the air extraction pipe 130 away from the sealing assembly 200, the sealing assembly 200 includes an extrusion ring 210 slidably connected to the surface of the air extraction pipe 130, and the side of the extrusion ring 210 away from the fixing ring 120 is fixedly connected with two A round shaft 220 is formed, and a threaded sleeve 230 is welded on the side of the round shaft 220 away from the extrusion ring 210. The threaded sleeve 230 is rotatably connected to the exhaust pipe 130. Four groups of connecting pipes 240 are fixedly connected inside the exhaust pipe 130. The four groups of connecting pipes 240 are fixedly connected to multiple groups of telescopic tubes 250 on the side away from the extrusion ring 210. A baffle 260 is slidably connected to the surface of the telescopic tube 250. An end of the baffle 260 away from the connecting tube 240 is fixedly connected to an airbag 270, and the airbag 270 is fixedly connected to one end of the telescopic tube 250.

[0026] By inserting the sleeve 110 into the borehole, and then rotating the threaded sleeve 230 to drive the round shaft 220 to rotate, the round shaft 220 drives the extrusion ring 210 to squeeze the gas between the sleeve 110 and the exhaust pipe 130, so that the gas passes into the connecting pipe 240, and then is diverted from the connecting pipe 240 into the multiple groups of telescopic tubes 250, so that the telescopic tubes 250 are extended from the sleeve 110 under the action of air pressure to drive the airbag 270 and the baffle 260 to extend and fit the inner wall of the borehole. When the airbag 270 is removed from the sleeve 110, it will expand and fit tightly to the inner wall of the borehole, which effectively improves the sealing effect of the borehole and avoids gas leakage when the gas is extracted. The sealing effect can be quickly achieved through the sealing component 200, thereby further improving the work efficiency.

[0027] Please refer to Figure 2 , Figure 3 and Figure 4 The six groups of fixing rings 120 are divided into three pairs, the baffles 260 are slidably connected between the fixing rings 120 , the baffles 260 are staggeredly distributed between the fixing rings 120 , and the baffles 260 are slidably connected to the sleeve 110 .

[0028] The baffles 260 can be effectively placed by the fixing rings 120. When the baffles 260 are removed, gas enters from the inside of the sleeve 110. By staggeredly distributing the baffles 260 between the fixing rings 120, gas leakage can be effectively prevented.

[0029] Please refer to Figure 1 , Figure 2 and Figure 5 The detection component 300 includes a piston cylinder 310 fixedly connected to one end of the surface of the exhaust pipe 130, a piston 320 is slidably connected inside the piston cylinder 310, a piston rod 330 is fixedly connected to the top of the piston 320, a spring 340 is sleeved on the surface of the piston rod 330, a vertical pipe 350 is connected to the bottom end of the piston cylinder 310, and a detection tube 360 ​​is connected to the side of the piston cylinder 310 away from the threaded sleeve 230, and a detector 370 is installed on the side of the detection tube 360 ​​away from the piston cylinder 310.

[0030] The gas is extracted through the exhaust pipe. When it is necessary to detect the gas inside the mine layer, the piston 320 is driven up by pulling the piston rod 330, so that the piston 320 squeezes the spring 340 and extracts gas from the exhaust pipe 130 through the vertical pipe 350, and the gas enters the detector 370 through the detection tube 360, so as to monitor the gas concentration inside the mine layer in real time, effectively ensuring the safety of the staff in subsequent work and avoiding accidents.

[0031] Please refer to Figure 5The top of the spring 340 is fixedly connected to the top of the inner wall of the piston cylinder 310 , and the bottom end of the vertical pipe 350 passes through the surface of the exhaust pipe 130 .

[0032] The vertical pipe 350 can effectively detect the gas extraction inside the exhaust pipe 130 in real time.

[0033] When in use, the sleeve 110 is inserted into the borehole, and then the threaded sleeve 230 is rotated to drive the round shaft 220 to rotate. The round shaft 220 drives the extrusion ring 210 to squeeze the gas between the sleeve 110 and the exhaust pipe 130, so that the gas passes into the connecting pipe 240, and then is diverted from the connecting pipe 240 into the multiple groups of telescopic tubes 250. The telescopic tubes 250 are extended from the sleeve 110 under the action of air pressure to drive the airbag 270 and the baffle 260 to extend and fit the inner wall of the borehole. When the airbag 270 is removed from the sleeve 110, it will expand and fit tightly to the inner wall of the borehole, which effectively improves the sealing effect of the borehole and avoids the gas being extracted and released. In the event of gas leakage, the sealing effect can be quickly achieved through the sealing component 200, thereby further improving work efficiency, and the gas is extracted through the exhaust pipe. When it is necessary to detect the gas inside the ore layer, the piston 320 is driven to rise by pulling the piston rod 330, so that the piston 320 squeezes the spring 340 and extracts gas from the exhaust pipe 130 through the vertical pipe 350, and the gas enters the detector 370 through the detection tube 360, so as to monitor the gas concentration inside the ore layer in real time, effectively ensuring the safety of the staff in performing subsequent work and avoiding accidents. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
