Description
Technical Field
[0001] The invention relates to the field of mine gas extraction, and in particular to a novel visible anti-blowout hole device for preventing blockage. Background Art
[0002] As the difficulty of mine gas control increases, gas control projects become particularly prominent. If on-site control is not in place during gas extraction drilling construction, gas blowouts are very likely to occur, leading to gas over-limit accidents. Therefore, anti-blowout hole devices are needed.
[0003] A common anti-blowout hole device is usually connected to a gas extraction device and a water and slag discharge device on the upper and lower sides of the anti-blowout hole cavity respectively, which can extract gas and discharge slag. However, it lacks a cleaning component for the cavity observation window, and is unable to clean the inside of the observation window, resulting in dirt in the cavity covering the observation window during operation, affecting the normal use of the observation window. At the same time, during the slag discharge process, the size and amount of the falling slag are uneven, which makes the slag discharge pipe easily blocked, thereby reducing the safety and practicality of the anti-blowout hole device.
[0004] Therefore, in view of the fact that the above-mentioned anti-blowout hole device lacks a window cleaning component and a slag discharge anti-blocking structure, and is unable to clean the inside of the observation window and prevent the slag discharge pipe from being blocked, a new type of visual anti-blowout hole device that prevents blockage can be designed. By pushing the connecting rod, the two magnetic push blocks can be driven to move inside the limit groove. When the magnetic push blocks move, the T-shaped magnetic blocks will move inside the slide groove under the action of magnetic force, so that the T-shaped magnetic blocks can drive the cleaning blocks on the side of the connecting plate to clean the inner walls of the chamber observation front window and the chamber observation rear window. At the same time, the telescopic rod can be controlled by the cylinder to drive the moving plate and the pull rod to move up and down. When the pull rod moves, it will drive the slider and the inner tooth ring on its top to move. Therefore, through the repeated up and down movement of the inner tooth ring, the slag inside the discharge connecting pipe can be made to fall more smoothly, avoiding the situation where large slag falls in large quantities and hits the inner wall of the discharge connecting pipe, causing the pipe to be blocked, so as to achieve the purpose of improving the safety of use. Summary of the invention
[0005] In order to overcome the common anti-blowout hole device, there is a lack of window cleaning components and slag discharge anti-blocking structure, and the inside of the observation window cannot be cleaned, resulting in dirt in the cavity covering the observation window during operation, affecting the normal use of the observation window. At the same time, during the slag discharge process, the size and amount of the falling slag are uneven, which makes the slag discharge pipe easily blocked, and it is time-consuming and laborious to clean it, thereby reducing the safety and practicality of the anti-blowout hole device.

When the magnetic push block moves, it will drive the T-shaped magnetic block inside the sliding seat to move inside the sliding groove, and the two T-shaped magnetic blocks can be moved synchronously through the connecting plate. At the same time, when the connecting plate moves driven by the T-shaped magnetic block, the cleaning block will move synchronously. When the cleaning block moves up and down, the inner side walls of the chamber observation front window and the chamber observation rear window can be cleaned to achieve the purpose of cleaning the windows, thereby preventing the windows from being covered with dirt and making it impossible to see the internal situation clearly. The cylinder can drive the telescopic rod to extend and retract up and down. When the telescopic rod is extending and retracting, it will drive the movable plate to move synchronously, and the movement of the movable plate will drive the pull rod to move synchronously. When the pull rod moves, it will drive the slider and the inner tooth ring on its top to move.

[0017] Beneficial effects of the present invention: 1. By pushing the connecting rod, the two magnetic push blocks can be driven to move inside the limit groove. When the magnetic push blocks move, they will drive the T-shaped magnetic blocks inside the sliding seat to move inside the sliding groove. The two T-shaped magnetic blocks can be moved synchronously through the connecting plate. At the same time, when the connecting plate moves driven by the T-shaped magnetic blocks, the cleaning block will move synchronously. When the cleaning block moves up and down, it can clean the inner wall of the chamber observation front window and the chamber observation rear window to achieve the purpose of cleaning the windows and avoid the windows being covered with dirt and making it impossible to see the internal situation clearly. 2. The cylinder can drive the telescopic rod to extend and retract up and down.

At the same time, the telescopic rod 17 can be driven up and down by the cylinder 16. When When the telescopic rod 17 is telescopic, it will drive the movable plate 18 to move synchronously, and the movement of the movable plate 18 will drive the pull rod 22 to move synchronously. When the pull rod 22 moves, it will drive the slider 20 and the inner tooth ring 19 on its top to move. When the inner tooth ring 19 moves, it will cause the slider 20 on the other side to move on the outside of the slide rod 21. Therefore, through the repeated up and down movement of the inner tooth ring 19, the slag inside the discharge connecting pipe 14 can fall more smoothly, avoiding the situation that large slag falls in large quantities and hits the inner wall of the discharge connecting pipe 14, causing the pipe to be blocked, so as to improve the safety of use.
[0025] Through the above steps, the two magnetic push blocks 5 can be driven to move inside the limit groove 4 by pushing the connecting rod 6. When the magnetic push block 5 moves, the T-shaped magnetic block 9 will move inside the slide groove 8 under the action of magnetic force, so that the T-shaped magnetic block 9 can drive the cleaning block 11 on the side of the connecting plate 10 to clean the inner wall of the chamber observation front window 2 and the chamber observation rear window 3. At the same time, the telescopic rod 17 can be controlled by the cylinder 16 to drive the moving plate 18 and the pull rod 22 to move up and down. When the pull rod 22 moves, it will drive the slider 20 and the inner tooth ring 19 on its top to move, so that the slag inside the discharge connecting pipe 14 can fall more smoothly through the repeated up and down movement of the inner tooth ring 19. It avoids the situation that large amounts of slag fall against the inner wall of the discharge connecting pipe 14 and cause the pipe to be blocked, so as to achieve the purpose of improving the safety of use. It solves the problem of common anti-blowout hole devices, which usually connect the gas extraction device and the water discharge and slag discharge device on the upper and lower sides of the anti-blowout hole cavity respectively, and can extract gas and discharge slag, but lacks a cleaning component for the cavity observation window, and cannot clean the inside of the observation window, resulting in dirt in the cavity covering the observation window during operation, affecting the normal use of the observation window. At the same time, during the slag discharge process, the size and quantity of the falling slag are uneven, which makes the slag discharge pipe easily blocked, thereby reducing the safety and practicality of the anti-blowout hole device.
