[0017] 1. This prefabricated prestressed concrete pipe pile core cleaning device is equipped with a gear plate and a rack plate. By turning the handle with external force, the gear plate can be rotated. Through the meshing structure of the gear plate and the rack plate, the rotation of the gear plate can cause the rack plate to rotate.

By turning on the second motor, the first bevel gear can be driven to rotate. Through the meshing structure of the first and second bevel gears, the rotation of the first bevel gear can cause the second bevel gear to rotate, which indirectly drives the hollow column to rotate. Then, through the threaded connection between the first threaded groove and the first threaded column, the rotation of the hollow column can cause the first threaded column to rise and fall, thereby driving the cleaning component to rise and fall to clean the inside of the pipe pile. In addition, the first annular retaining ring can be disassembled and assembled through the second threaded groove and the second threaded column, and it is also convenient to extend the first threaded column.

[0029] Furthermore, the rotating plate 8 and the first rotating shaft 7 form a rotating structure through the operation of the first motor 6, and the rotating plate 8 and the cleaning cone 9 form a fixed structure. The rotating plate 8 also forms a rotating structure through the second bearing 10 and the hand handle 11, and the hand handle 11 forms a fixed structure with the gear plate 12. When the first motor 6 is turned on, the rotating plate 8 can be driven to rotate. The rotation of the rotating plate 8 can drive the cleaning cone 9 and the cleaning and grinding plate 19 to rotate, cleaning the inside of the pipe pile. By turning the hand handle 11 with external force, the gear plate 12 can be driven to rotate.

The rack plate 13 forms a sliding structure with the cylindrical slider 16 through the arc-shaped sliding groove 15, and the cylindrical slider 16 forms a fixed structure with the cleaning and grinding plate 19 through the telescopic rod 17. The rotation of the rack plate 13 causes the cylindrical slider 16 to slide through the arc-shaped sliding groove 15, which indirectly drives the telescopic rod 17 and the cleaning and grinding plate 19 to move.

[0031] Furthermore, the first bevel gear 27 and the second rotating shaft 26 form a rotating structure through the operation of the second motor 25, and the first bevel gear 27 and the second bevel gear 28 form a meshing structure; by turning on the second motor 25, the first bevel gear 27 can be driven to rotate. Through the meshing structure of the first bevel gear 27 and the second bevel gear 28, the rotation of the first bevel gear 27 can cause the second bevel gear 28 to rotate, indirectly driving the hollow column 3 to rotate.

[0032] Furthermore, the second bevel gear 28 and the hollow column 3 form a fixed structure, and the hollow column 3 forms a rotating structure with the support frame 1 through the first bearing 2; by turning on the second motor 25, the first bevel gear 27 can be driven to rotate. Through the meshing structure of the first bevel gear 27 and the second bevel gear 28, the rotation of the first bevel gear 27 can cause the second bevel gear 28 to rotate, which indirectly drives the hollow column 3 to rotate.

[0033] Furthermore, the hollow column 3 is threadedly connected to the first threaded column 5 via the first threaded groove 4, and the first threaded column 5 is detachably connected to the first annular retaining ring 32 via the second threaded groove 30 and the second threaded column 31. The first annular retaining ring 32 is also engaged with the supporting retaining column 33. Through the threaded connection between the first threaded groove 4 and the first threaded column 5, the rotation of the hollow column 3 can cause the first threaded column 5 to rise and fall, thereby driving the cleaning component to rise and fall to clean the inside of the pipe pile. Secondly, the first annular retaining ring 32 can be disassembled and assembled via the second threaded groove 30 and the second threaded column 31, which also facilitates the lengthening of the first threaded column 5.

[0034] Working principle: First, the operator needs to rotate the handle 11 by external force, which will drive the gear plate 12 to rotate. The rotation of the gear plate 12 will cause the rack plate 13 to rotate. The rotation of the rack plate 13 will cause the cylindrical slider 16 to slide through the arc-shaped slide groove 15, indirectly driving the telescopic rod 17 and the cleaning and grinding plate 19 to move. By adjustment, the outermost parts of the three sets of cleaning and grinding plates 19 can be made to fit with the pipe pile. By turning on the first motor 6, the rotating plate 8 can be driven to rotate. The rotation of the rotating plate 8 can drive the cleaning cone 9 and the cleaning and grinding plate 19 to rotate, thus cleaning the inside of the pipe pile. The cleaning process begins, and then the second motor 25 is activated, which drives the first bevel gear 27 to rotate. Through the meshing structure of the first bevel gear 27 and the second bevel gear 28, the rotation of the first bevel gear 27 causes the second bevel gear 28 to rotate, indirectly driving the hollow column 3 to rotate. The rotation of the hollow column 3 causes the first threaded column 5 to rise and fall, thereby driving the cleaning assembly to rise and fall to clean the inside of the pipe pile. Furthermore, the first annular retaining ring 32 can be disassembled and assembled through the second threaded groove 30 and the second threaded column 31, which also facilitates the lengthening of the first threaded column 5.
