At the same time, it solves the problem that traditional equipment makes it difficult to test and determine whether particles will dissolve, expand, or break during long-term use, thus affecting the stability of their sealing performance.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4The disassembly mechanism 2 is located at the bottom of the mining pipe 4 and is used to disassemble the particle tester 5. The disassembly mechanism 2 includes a receiving component, a plugging component, and a translation component. The receiving component is located at the bottom of the mining pipe 4 and is used to receive the particle tester 5. The plugging component is located at the bottom of the receiving component and is used to position the particle tester 5. The translation component is located on both sides of the receiving component and is used to facilitate the translation of the receiving component. The receiving component includes two sliding strips 21 fixed to the bottom of the mining pipe 4. Support seats 22 are slidably mounted on the outer walls of the two sliding strips 21. Card seats 25 are fixed on both sides of the top of the support seats 22. Disassembly plates 28 are fixed on both sides of the particle tester 5. The interior of each card seat 25 has a sliding groove for the disassembly plate 28 to slide. The plugging component includes a movable seat 210 and a fixed seat 212 fixed to the bottom of the support seat 22. An arc-shaped insert plate 29 is inserted into the interior of the movable seat 210, extending to the card seat 25. The arc-shaped insert 29 is internally connected to the disassembly plate 28 and a control plate 214 is fixed on one side. A control component for controlling the arc-shaped insert 29 is provided between the arc-shaped insert 29 and the fixed seat 212. The control component includes an arc-shaped rod fixed on one side of the bottom of the arc-shaped insert 29. The arc-shaped rod is movably inserted into the interior of the fixed seat 212. A compression spring 211 is connected between the arc-shaped insert 29 and the fixed seat 212. The compression spring 211 is sleeved on the outer wall of the arc-shaped rod. A baffle 213 is fixed at the bottom of the support seat 22. The arc-shaped rod corresponds to the baffle 213.

The two movable rods 23 extend to one side of the first fixed ring 24 and are jointly fixed with the control arc plate.

[0029] First, pull the control plate 214 to move the arc-shaped insert plate 29. The movement of the arc-shaped insert plate 29 causes the arc-shaped rod to move inside the fixed seat 212. The movement of the arc-shaped rod causes the compression spring 211 to contract on its outer wall. The contraction of the compression spring 211 causes the arc-shaped insert plate 29 to separate from the disassembly plate 28. After the arc-shaped insert plate 29 and the disassembly plate 28 are separated, pull the support seat 22 to move on the outer wall of the slide bar 21. The two movable rods 23 are inserted into and retracted from the first fixed ring 24. The cooperation between the support seat 27 and the telescopic rod allows the support seat 22 to move horizontally at the bottom of the mining pipe 4, while also reinforcing it to make it more stable during movement. The movement of the support seat 22 drives the two clamping seats 25 to move synchronously. The movement of the clamping seats 25 separates them from the disassembly plate 28. After the clamping seats 25 and the disassembly plate 28 are separated, the particle tester 5 is pulled to separate the detector 7 from the mining pipe 4, thus enabling the particle tester 5 to be disassembled and replaced.

The interior of the 33 is equipped with a high-pressure water pump 35, and the outlet of the high-pressure water pump 35 is connected to a water supply pipe 36, which is connected to a water storage plate 31. There are two water storage plates 31 and two high-pressure water pumps 35. The two water storage plates 31 are located on the outer wall of the mining pipe 4, and the two water storage plates 31 are pressed in opposite directions. The purpose is to completely flush the inside of the mining pipe 4. The two water storage plates 31 can work independently or synchronously through the two high-pressure water pumps 35, both for better flushing of the mining pipe 4.

[0031] The high-pressure water pump 35 supplies water from the water tank 33 to the water supply pipe 36, which then transports the water to the water storage plate 31. The water is then flushed through multiple flushing pipes 32. During the mining process, the inside of the mining pipe 4 may become blocked due to mineral deposits, debris accumulation, or the adhesion of organic substances such as wax or asphalt. By flushing the mining pipe 4, these blockages can be effectively removed, ensuring the smooth flow of fluid inside the mining pipe 4.
