Problems solved by technology

[0002] In the mining process of coal mines, coal mine gas is one of the main risk factors that threaten the safety of coal mines. Therefore, it is generally necessary to use the method of pre-extracting gas to control coal seam gas, and these drilling holes on the coal rock wall need to be cleaned. For the sealing treatment, the current coal mine gas drainage sealing device has the problem that it is inconvenient to fix the sealing device, which makes the sealing device vulnerable to external force and affects the sealing effect. For this reason, we propose a convenient Adjustable Coal Mine Gas Drainage Sealing Device

Embodiment 1

[0032] see Figure 1-6 As shown, a coal mine gas drainage and sealing device that is easy to adjust includes a lifting console 1, a liquid suction pump 2, an external socket 3, a suction sealing mechanism 4, an adjusting screw 5 and a switchable fixed point. type plug-in component 6;

[0033] The liquid suction pump 2 is fixedly installed on the top of the lifting console 1. As a technical optimization scheme of the present invention, the lifting console 1 is provided with a groove at the suction end of the liquid suction pump 2, and the suction end of the liquid suction pump 2 Soft pipeline 8 is installed, and telescopic deck 7 is installed on the bottom of lifting console 1, and soft pipeline 8 is stuck in telescopic deck 7.

[0034]In the actual use of the device, it is only necessary to insert the soft pipe 8 into the position of the liquid to be extracted, and at the same time place a container on the top of the lifting console 1, and use the suction effect of the liquid...

Embodiment 2

[0042] In this embodiment, on the basis of Example 1, the structure of the air-suction sealing mechanism 4 is embodied. The air-extraction sealing mechanism 4 includes a soft regulating pipe 4-1, a hard ventilation pipe 4-2, and a connecting bracket 4. -3. Adjust mine explosion-proof motor 4-4, inflatable pipe 4-5, drill bit 4-6, inflatable joint 4-7, inflatable pump 4-8 and telescopic pipe 4-9, hard air pipe 4-2 through The soft regulating pipe 4-1 is connected with the external socket 3.

[0043] When the air extraction and sealing mechanism 4 is actually used, use the hard vent pipe 4-2 to insert into the gas extraction hole, connect the external socket 3 with the extraction equipment, so that the gas is sucked through the hard vent pipe 4-2, and then After the soft regulating pipe 4-1 enters the external socket 3, gas extraction is realized. The setting of the soft regulating pipe 4-1 makes the hard vent pipe 4-2 have certain flexibility, which is convenient for the hard v...
