[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A device for preventing clogging of prestressed concrete pipe piles includes: a shell 1; six first through holes 2 evenly distributed at the bottom of the shell 1; a top cover 3 provided at the top of the shell 1; a limiting ring 4 fixedly connected to the bottom of the top cover 3; six second through holes 5 evenly distributed inside the shell 1; a filter element 6 provided inside the shell 1; a locking mechanism 7 for quick replacement of the filter element 6 provided near the limiting ring 4; and an expansion mechanism 8 adapted to different diameters provided on the outer surface of the shell 1. The user uses the expansion mechanism 8 to lock the device inside the concrete pipe pile. Water flows through the first through holes 2, passes through the filter element 6, and then exits through the second through holes 5, and is then filtered by the internal filter element 6, preventing clogging of the concrete pipe pile. The locking mechanism 7 allows for quick replacement of the filter element 6, preventing a reduction in its filtration effect.

[0027] like Figure 4 and Figure 5As shown, the engaging mechanism 7 has six evenly spaced ball grooves 9 near the limiting ring 4 on the housing 1. Steel balls 10 are placed inside the ball grooves 9. A lifting ring 11 is slidably connected to the housing 1 near the steel balls 10. A connecting ring 12 is fixedly connected to the outer surface of the lifting ring 11. A matching stroke groove 13 is provided near the connecting ring 12 on the housing 1. A force-applying ring 14 is fixedly connected to the outer surface of the connecting ring 12. A movable groove 15 is provided on the inner wall of the lifting ring 11, and a locking groove 16 is provided on the outer surface of the limiting ring 4. The movable groove 15 and the locking groove 16 are compatible with the steel balls 10. The user can pull the force-applying ring 14, which is connected to the connecting ring 14. Ring 12 drives lifting ring 11, causing the movable groove 15 on lifting ring 11 to move to ball groove 9, increasing the range of motion of steel ball 10. Then, the user pulls the top cover 3, which drives the limiting ring 4, causing the limiting ring 4 to separate from the housing 1, thus opening the device and taking out the filter element 6 inside for replacement. Then, the limiting ring 4 on the top cover 3 is inserted into the housing 1, and the force ring 14 is released, causing lifting ring 11 to rise and reset. As lifting ring 11 rises, it causes the movable groove 15 to separate from ball groove 9 and squeezes steel ball 10, causing a small portion of steel ball 10 to enter the slot 16 of limiting ring 4, thereby replacing filter element 6.

[0028] like Figure 4 As shown, a first spring 17 is provided at the bottom of the lifting ring 11. The first spring 17 is located inside the housing 1. A damping pad 18 is sleeved on the outer surface of the force ring 14. The damping pad 18 is fixedly connected to the force ring 14 and can push the lifting ring 11 to reset.

[0029] like Figure 4 As shown, the filter element 6 has a sponge layer 19 inside, an activated carbon granule layer 20 on top of the sponge layer 19, and a cotton yarn layer 21 on top of the activated carbon granule layer 20. The filter element 6 has a number of evenly arranged circular holes 22 inside. A second spring 23 is provided between the filter element 6 and the housing 1. The second spring 23 is located inside the housing 1, which improves the filtration effect of the filter element 6.

[0030] like Figure 2 and Figure 3As shown, the expansion mechanism 8 includes: an airbag 24 fixedly connected to the surface of the housing 1, a connecting block 25 on the top of the airbag 24; an air hole 26 is opened inside the connecting block 25, a sealing bead 27 is arranged inside the air hole 26, a conical spring 28 is arranged at the bottom of the sealing bead 27, a filter plate 29 is arranged at the bottom of the conical spring 28, and the filter plate 29 is fixedly connected to the connecting block 25. The user places the device inside the concrete pipe pile, and then connects the output end of the air pump to the connecting block 25. The air pump inflates the airbag through the connecting block 25. The gas pushes the sealing bead 27, causing the sealing bead 27 to separate from the air hole 26. The gas enters the airbag 24 through the gap between the sealing bead 27 and the air hole 26, increasing the volume of the airbag 24. When the air pump stops supplying gas, the conical spring 28 pushes the sealing bead 27, causing the sealing bead 27 to seal the air hole 26, thereby locking the device inside the concrete pipe pile. When venting, the user presses the sealing bead 27.

[0031] like Figure 4 and Figure 5 As shown, a sealing ring 30 is fitted on the top outer surface of the limiting ring 4. The sealing ring 30 is adapted to the housing 1 and the top cover 3, which improves the sealing performance at the connection between the limiting ring 4 and the housing 1.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a fixing block 31 is fixedly connected to the center of the top of the top cover 3, and a rotating shaft 32 is rotatably connected to the center of the fixing block 31. A pull ring 33 is fixedly connected to the top of the rotating shaft 32. The user can pull the pull ring 33, which drives the rotating shaft 32. The rotating shaft 32 drives the device through the fixing block 31, thus making it convenient for the user to remove the device from inside the concrete pipe pile.

[0033] Working principle: The user can pull the force ring 14, which drives the lifting ring 11 through the connecting ring 12, causing the movable groove 15 on the lifting ring 11 to move to the ball groove 9, increasing the range of motion of the steel ball 10. Then, the user pulls the top cover 3, which drives the limiting ring 4, causing the limiting ring 4 to separate from the housing 1, thus opening the device. The filter element 6 inside the device can then be removed and replaced. After that, the limiting ring 4 on the top cover 3 is inserted into the housing 1, and the force ring 14 is released. The lifting ring 11 rises and resets, and the lifting ring 11 moves upwards simultaneously with the ball groove 9. The movable groove 15 separates from the ball groove 9 and squeezes the steel ball 10, causing a small portion of the steel ball 10 to enter the slot 16 of the limiting ring 4, thereby replacing the filter element 6. This simplifies the opening process of the device and the replacement process of the filter material, improving practicality. It solves the problem that although the existing anti-clogging device for prestressed concrete pipe piles can prevent the concrete pipe piles from clogging, the filtration effect of the filter material gradually decreases after long-term use, requiring continuous rotation and opening of the device to replace the filter material inside the device, which is a relatively complicated replacement process.

[0034] The user places the device inside the concrete pipe pile, then connects the air pump to the output end of the connecting block 25. The air pump inflates the air bladder through the connecting block 25. The gas pushes the sealing bead 27, causing it to separate from the air hole 26. The gas enters the air bladder 24 through the gap between the sealing bead 27 and the air hole 26, increasing the volume of the air bladder 24. When the air pump stops supplying air, the conical spring 28 pushes the sealing bead 27, sealing the air hole 26 and securing the device inside the concrete pipe pile. To release air, the user presses the sealing bead 27. This allows the device to be adjusted according to the diameter of the concrete pipe pile, improving its application range and solving the problem that existing anti-clogging devices for prestressed concrete pipe piles cannot be adjusted according to the diameter of the concrete pipe pile, resulting in a limited range of applications.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
