[0030] The outer wall of the top coal position tracker 5 is provided with a slider 17, and the outer wall of the slider 17 matches the interior of the fixed slide rail 3. The top coal position tracker 5 is inserted into the fixed slide rail 3 through the slider 17, which facilitates the movement of the top coal position tracker 5 within the outer shell body 1.

[0031] The outer wall of the top coal position tracker 5 is provided with a waterproof layer 6, and the material of the waterproof layer 6 is a polyurethane waterproof coating. It is composed of an emulsion synthesized from a variety of water-based polymers and high-quality cement mixed with various additives. The flexibility of the polymer (resin) and the rigidity of the cement are combined into one, which makes it perform well in terms of impermeability and stability, and facilitates the waterproof and oil-proof effect at the top coal position tracker 5.

[0032] The outer wall of the top coal position tracker 5 is provided with a threaded layer 7, and the outer wall of the threaded layer 7 is provided with a positioning mechanism for fixing the position.

[0033] The positioning mechanism includes a limiting fixing block 8 and a second threaded groove 9. The outer wall of the threaded layer 7 is provided with a limiting fixing block 8, and the outer wall of the limiting fixing block 8 is provided with a second threaded groove 9. The outer wall of the second threaded groove 9 matches the outer wall of the threaded layer 7. By rotating the limiting fixing block 8, the second threaded groove 9 is driven to mesh with the threaded layer 7, thereby facilitating the installation and removal of the limiting fixing block 8 from the outer wall of the top coal position tracking instrument 5.

[0034] The outer wall of the limiting and fixing block 8 is provided with an arc-shaped groove 10, and a fixing shaft 11 is provided inside the arc-shaped groove 10. The fixing shaft 11 drives the arc-shaped fixing block 12 to rotate within the arc-shaped groove 10, making it easy to adjust the position of the arc-shaped fixing block 12.

[0035] An S-shaped elastic plate 14 is provided inside the arc groove 10, and the outer wall of the S-shaped elastic plate 14 matches the outer wall of the arc-shaped fixing block 12. The position of the arc-shaped fixing block 12 is adjusted by flipping, so that the S-shaped elastic plate 14 undergoes elastic deformation. When the arc-shaped fixing block 12 is no longer compressed, the arc-shaped fixing block 12 is driven to insert into the arc-shaped positioning block 4 under the elastic force of the S-shaped elastic plate 14 itself, so that the waterproof layer 6 is fixed in the position inside the outer shell body 1.

The outer wall of the positioning mechanism is matched with the inside of the arc-shaped positioning block 4.

[0038] By inserting the top coal position tracker 5 into the outer pipe shell body 1, the positioning mechanism needs to be installed on the outer wall of the top coal position tracker 5 first. The second threaded groove 9 is engaged with the outer wall of the threaded layer 7 by rotating the limiting fixed block 8, so that the limiting fixed block 8 is fixed on the outer wall of the top coal position tracker 5. Then the top coal position tracker 5 is inserted into the outer pipe shell body 1, so that the sliding block 17 of the top coal position tracker 5 slides in the fixed slide 3, and the arc-shaped fixed block 12 is turned over outward along the inner wall of the first threaded groove 2, so that the S-shaped elastic plate 14 and the reset torsion spring 13 are elastically deformed. When the arc-shaped fixed block 12 moves to the position opposite to the arc-shaped positioning block 4, the arc-shaped fixed block 12 is inserted into the arc-shaped positioning block 4 under the elastic force of the S-shaped elastic plate 14 and the reset torsion spring 13, thereby facilitating the fixation of the top coal position tracker 5 in the outer pipe shell body 1. When the top coal position tracker 5 is in the appropriate position, the next top coal position tracker 5 can be placed, thereby completing a series of work, solving the problems of slow speed and low efficiency in the process of placing the top coal position tracker 5, and realizing accurate monitoring of the movement of the top coal.

[0039] When the top coal position tracker 5 needs to be taken out from the outer pipe shell body 1, the third threaded groove 16 is engaged with the first threaded groove 2 by rotating the push rod 15, so that the push rod 15 extrudes the top coal position tracker 5, the arc-shaped fixed block 12 of the top coal position tracker 5 is turned over inward, the S-shaped elastic plate 14 is elastically deformed in the arc-shaped groove 10, and the reset torsion spring 13 is tightened, and then the top coal position tracker 5 drives the arc-shaped fixed block 12 to move outward along the inner wall of the first threaded groove 2, thereby completing the disassembly.

[0040] The outer wall of the top coal position tracker 5 is provided with a waterproof layer 6. The waterproof layer 6 is composed of an emulsion synthesized by a plurality of water-based polymers and high-quality cement mixed with various additives, so that it has excellent impermeability and stability, and the top coal position tracker 5 can be waterproofed and oiled.

[0041] The application is described above in conjunction with the drawings, and it is obvious that the specific implementation of the application is not limited by the above manner, as long as various non-essential improvements are made by using the method concept and technical solution of the application, or the concept and technical solution of the application is directly applied to other occasions without improvement, which are all within the protection scope of the application.
