[0022] The present utility model provides a safety device for gas drainage and treatment, including a bottom plate 101 and a mining and treatment mechanism. The mining and treatment mechanism includes a mounting frame 102, a lead screw 103, a motor 104, a lifting plate 105, a support plate 106, a separation pipe 107, a drill pipe 108, a water inlet pipe 109, a first one-way valve 110, a plurality of rollers 111, an exhaust assembly, two groups of guiding assemblies, and a treatment assembly.

Each group of guiding assemblies includes a guiding rod 121 and a limiting block 122. The foregoing solution solves the problem in the prior art that workers need to manually adjust the height of the device, resulting in a relatively high labor intensity for workers.

[0023] For this specific embodiment, a plurality of the rollers 111 are all arranged on the lower surface of the bottom plate 101, the mounting frame 102 is fixedly connected to the upper surface of the bottom plate 101, the lead screw 103 penetrates through the lifting plate 105 and is in threaded cooperation with the lifting plate 105. One end of the lead screw 103 is rotatably connected to the bottom plate 101, and the other end of the lead screw 103 is rotatably connected to the mounting frame 102. The motor 104 is arranged on the upper surface of the mounting frame 102, and the output end of the motor 104 is fixedly connected to the lead screw 103. The support plate 106 is fixedly connected to the lifting plate 105. The separation pipe 107 is arranged on the upper surface of the support plate 106. The drill pipe 108 is arranged at one end of the separation pipe 107. The water inlet pipe 109 is arranged at the end of the separation pipe 107 away from the drill pipe 108. The first one-way valve 110 is arranged at one end of the water inlet pipe 109. The exhaust assembly is arranged in the middle of the separation pipe 107. The treatment assembly is arranged on the upper surface of the bottom plate 101. Both groups of the guiding assemblies are slidably connected to the support plate 106. When specifically in use, the motor 104 is started. The output end of the motor 104 drives the lead screw 103 to rotate, so that the lifting plate 105 moves upward or downward. The lifting plate 105 drives the support plate 106 to move, and the support plate 106 drives the separation pipe 107 to move until the drill pipe 108 is moved to the height where gas extraction is required. Then the drill pipe 108 is inserted into the coal mining face, so that gas flows into the separation pipe 107 through the drill pipe 108. Then water mist is sprayed into the separation pipe 107 through the water inlet pipe 109, so that the coal dust and water mist in the gas flow into the treatment assembly together for treatment, and the gas is output through the exhaust assembly.

[0024] Among them, the exhaust pipe 112 is fixedly connected to the separation pipe 107. The second one-way valve 113 is arranged at one end of the exhaust pipe 112. The flow meter 114 is fixedly connected to the exhaust pipe 112. When specifically in use, the gas is output and used through the exhaust pipe 112. The second one-way valve 113 prevents the gas in the exhaust pipe 112 from flowing back, and the flow meter 114 measures the gas.

[0025] Secondly, the fixing member is used to fix the tank body 115. The connecting pipe 117 penetrates through the support plate 106. One end of the connecting pipe 117 is fixedly connected to the separation pipe 107, and the other end of the connecting pipe 117 is fixedly connected to the tank body 115. The sleeve 116 is sleeved on the lower end of the tank body 115 and is threadedly connected to the tank body 115. The drain pipe 118 is fixedly connected to the tank body 115. During specific use, water exceeding the height of the lower end of the drain pipe 118 is added into the tank body 115 to prevent gas from leaking through the drain pipe 118. Coal dust and water mist flow into the tank body 115 through the connecting pipe 117, and the coal dust will deposit inside the tank body 115. When the water level height in the tank body 115 exceeds the height of the upper end of the drain pipe 118, the water in the tank body 115 will be discharged through the drain pipe 118. After the extraction is completed, the sleeve 116 is unscrewed to discharge the coal ash in the tank body 115.

[0026] Meanwhile, the circular ring 119 is sleeved on the outer side of the tank body 115 and is fixedly connected to the tank body 115. One ends of the two fixing plates 120 are respectively fixedly connected to the bottom plate 101, and the other ends of the two fixing plates 120 are respectively fixedly connected to the circular ring 119. During specific use, the circular ring 119 is fixed by the two fixing plates 120, thereby fixing the tank body 115.

[0027] In addition, the guide rod 121 penetrates through the support plate 106 and is slidably connected to the support plate 106. One end of the guide rod 121 is fixedly connected to the bottom plate 101, and the other end of the guide rod 121 is fixedly connected to the limit block 122. During specific use, the lifting plate 105 moves up and down, causing the support plate 106 to slide on the guide rod 121, thereby guiding the support plate 106.

[0028] When using a safety device for gas drainage and control in this embodiment, during specific use, water is added into the tank body 115 to a height exceeding the lower end of the drain pipe 118 to prevent gas from leaking through the drain pipe 118. Then, the motor 104 is started, and the output end of the motor 104 drives the lead screw 103 to rotate, causing the lifting plate 105 to move upward or downward. The lifting plate 105 drives the support plate 106 to move, and the support plate 106 drives the separation pipe 107 to move until the drill pipe 108 is moved to the height where gas needs to be drained. Then, the drill pipe 108 is inserted into the coal mining face, allowing gas to flow into the separation pipe 107 through the drill pipe 108. Then, water mist is sprayed into the separation pipe 107 through the water inlet pipe 109, causing coal dust and water mist in the gas to flow into the tank body 115 through the connecting pipe 117. The coal dust will deposit inside the tank body 115. When the water level in the tank body 115 exceeds the upper end of the drain pipe 118, the water in the tank body 115 will be discharged through the drain pipe 118, and the gas will be output through the exhaust pipe 112 for use. This method can effectively solve the problem in the prior art that workers need to manually adjust the height of the device, resulting in a relatively high labor intensity for workers.

[0032] For this specific embodiment, one end of each of the two inclined rods 201 is fixedly connected to the bottom plate 101, and the other end of each of the two inclined rods 201 is fixedly connected to the grip rod 202. The anti-slip sleeve 203 is sleeved outside the grip rod 202. During specific use, the grip rod 202 is fixed by the two inclined rods 201, the friction of the grip rod 202 can be enhanced through the anti-slip sleeve 203, and the bottom plate 101 can be conveniently pushed through the grip rod 202.

[0033] When using a safety device for gas drainage and control in this embodiment, during specific use, the grip rod 202 is pushed, and the grip rod 202 drives the bottom plate 101 to move through the two inclined rods 201, causing multiple rollers 111 to rotate, thereby facilitating the movement of the device.
