Figure 2 It is a front view of the whole of the first embodiment of the utility model. Figure 3 It is an overall side view of the first embodiment of the utility model.

[0023] The utility model provides a coal mine goaf drainage device: including a drainage device body 101 and a plug-in assembly, the plug-in assembly including a sleeve pipe 102, a mounting ring 103 and two resistance structures 104, the resistance structure 104 including a support seat 105, a support frame 106, an operating member 107, a connecting plate 108, an arc-shaped resistance plate 109 and a guide member 110, the operating member 107 including an operating screw 111, a telescopic rod 112 and a knob 113, the guide member 110 including a guide sleeve 114 and a guide rod 115, the resistance structure 104 also including a rebound layer 116 and an anti-skid pad 117, the above-mentioned scheme solves the existing coal mine goaf drainage device, because the water pipe in the drainage device body 101 is directly connected to the water pump without any fixed structure, the water pump will vibrate during the drainage process, which may cause the connection to fall off and affect the subsequent drainage operation.

[0024] For this specific implementation, the drainage device body 101 is used to be placed in the goaf of a coal mine for drainage operations. The specific structure and usage method refer to the patent document with publication number CN117504402A, which will not be described in detail here.

[0025] Among them, the sleeve pipe 102 is communicated with the drainage device body 101 and is located on one side of the drainage device body 101; the mounting ring 103 is fixedly connected to the sleeve pipe 102 and is located on one side of the sleeve pipe 102; the two interference structures 104 are respectively located on both sides of the mounting ring 103; the support seat 105 is fixedly connected to the mounting ring 103 and is located on one side of the mounting ring 103; the support frame 106 is fixedly connected to the support seat 105 and is located on one side of the support seat 105; the operating member 107 is arranged on one side of the support frame 106; the connecting plate 108 is fixedly connected to the operating member 107 and is located on one side of the operating member 107; the arc-shaped interference plate 109 is fixedly connected to the connecting plate 108 and is located on one side of the connecting plate 108; the guide member 110 is arranged between the support frame 106 and the connecting plate 108 When using the drainage device body 101 to perform drainage operations, the suction pipe on the water pump is plugged into the sleeve pipe 102, and then the resistance structure 104 on both sides of the mounting ring 103 is operated, and the support seat 105 is used to install the support frame 106 on the mounting ring 103, and the operating member 107 on the support frame 106 is twisted to cooperate with the guide member 110 to drive the connecting plate 108 to move, and the connecting plate 108 drives the arc-shaped resistance plate 109 to resist both sides of the suction pipe of the water pump, so that the connection between the suction pipe of the water pump and the sleeve pipe 102 is more stable, thereby solving the existing coal mine underground goaf drainage device. Since the water pipe in the drainage device body 101 is directly connected to the water pump without any fixed structure, the water pump will vibrate during the drainage process, which may cause the connection to fall off and affect the subsequent drainage operations.

[0026] Secondly, the operating screw 111 is rotatably connected to the support frame 106 and is located on one side of the support frame 106; the telescopic rod 112 is threadedly connected to the operating screw 111, and is fixedly connected to the connecting plate 108, and is located on one side of the operating screw 111; the knob 113 is fixedly connected to the operating screw 111 and is located on one side of the operating screw 111. When the water suction pipe of the water pump is plugged into the sleeve pipe 102, the knob 113 is twisted to rotate the operating screw 111. The rotation of the operating screw 111 drives the telescopic rod 112 to drive the connecting plate 108 to move through threaded transmission in cooperation with the guide member 110, so that the arc-shaped contact plate 109 contacts and fixes the sleeved water suction pipe, making the connection between the water suction pipe and the sleeve pipe 102 more stable.

[0027] Meanwhile, the guide sleeve 114 is fixedly connected to the support frame 106 and is located on one side of the support frame 106; the guide rod 115 is slidably connected to the guide sleeve 114, is fixedly connected to the connecting plate 108, and is located on one side of the guide sleeve 114. The guide sleeve 114 is used to support the sliding of the guide rod 115. When the connecting plate 108 drives the arc-shaped abutting plate 109 to move, the guide rod 115 provides a guiding and limiting function, so that the arc-shaped abutting plate 109 can move smoothly.

[0028] In addition, the elastic layer 116 is fixedly connected to the arc-shaped abutting plate 109 and is located on one side of the arc-shaped abutting plate 109; the anti-slip pad 117 is fixedly connected to the elastic layer 116 and is located on one side of the elastic layer 116. When the arc-shaped abutting plate 109 abuts against the water suction pipe of the water pump, the elastic layer 116 provides elastic tension to cooperate with the anti-slip pad 117 to increase the friction force of the contact surface, so that the abutting of the arc-shaped abutting plate 109 is more stable.

[0029] When using the coal mine goaf drainage device described in this embodiment, place the drainage device body 101 into the coal mine goaf, then insert the water suction pipe on the water pump into the sleeve pipe 102, and then operate the abutting structures 104 on both sides of the mounting ring 103. The support base 105 is used to install the support frame 106 on the mounting ring 103. Twist the knob 113 on the support frame 106 to make the operating screw 111 rotate. The rotation of the operating screw 111 drives the telescopic rod 112 through a threaded transmission method, and cooperates with the guiding member 110 to drive the connecting plate 108 to move, so that the arc-shaped abutting plate 109 abuts against and fixes the sleeved water suction pipe. When the arc-shaped abutting plate 109 abuts against the water suction pipe of the water pump, the elastic layer 116 provides elastic tension to cooperate with the anti-slip pad 117 to increase the friction force of the contact surface, so that the connection between the water suction pipe of the water pump and the sleeve pipe 102 is more stable, thus solving the problem that in the existing coal mine goaf drainage device, since the water pipe in the drainage device body 101 is directly connected to the water pump without any fixing structure, the water pump will generate vibration during the drainage process, which may cause the connection to fall off and affect the subsequent drainage operation.

[0030] The second embodiment of this application is as follows:

[0031] Please refer to Figure 4 , in which, Figure 4 is the overall structural schematic diagram of the second embodiment of the present utility model.

[0032] Based on the first embodiment, a drainage device for gob areas in coal mines provided by the present utility model, the plug-in component further includes a reinforcing member 201, and the reinforcing member 201 includes an expansion layer 202 and a sealing gasket 203.

[0033] Wherein, the reinforcing member 201 is arranged on one side of the sleeve pipe 102, and the reinforcing member 201 is used to increase the connection tightness when the water suction pipe of the water pump is sleeved with the sleeve pipe 102.

[0034] Secondly, the expansion layer 202 is fixedly connected to the sleeve pipe 102 and is located on one side of the sleeve pipe 102; the sealing gasket 203 is fixedly connected to the expansion layer 202 and is located on one side of the expansion layer 202. When the water suction pipe of the water pump is sleeved with the sleeve pipe 102, the expansion layer 202 provides an expansion force to make the sealing gasket 203 closely fit the inner wall of the water suction pipe.

[0035] When using the drainage device for gob areas in coal mines described in this embodiment, when the water suction pipe of the water pump is sleeved with the sleeve pipe 102, the expansion layer 202 provides an expansion force to make the sealing gasket 203 closely fit the inner wall of the water suction pipe.
