Example 4

Referring to fig. 7 to 9, the waterproof device for the fabricated building pipe in embodiment 4 of the present invention is improved based on embodiment 1.

Particularly, in embodiment 1, the pipeline 3 is waterproofed by extrusion, and as the service life is longer and longer, the concrete is further shrunk, which may cause that the previously adjusted extrusion strength becomes unsuitable for the current required strength for waterproofing, because the shrinkage of the concrete, the gap will become larger, and the nut 134 is fixed in position, the elastic waterproof member 12 will become loose before along with the increase of the gap, the extrusion on the wall of the pipeline 3 and the wall of the pre-buried pipe 11 will be reduced, water seepage may occur at the gap between the joints of the two pipelines 3, and the pipeline 3 is in the wall 2, which is inconvenient for readjusting the nut 134. Therefore, in the embodiment, an automatic compensation mechanism 5 is additionally arranged near the nut 134, the automatic compensation mechanism 5 can automatically screw the nut 134 according to the shrinkage of the concrete, so that the elastic waterproof member 12 becomes loose, the nut 134 further presses the first clamping member 131, the elastic waterproof member 12 is pressed, the elastic waterproof member 12 is attached to the pipeline 3 and the embedded pipe 11 again, sufficient pressing force is generated on the pipeline 3 and the embedded pipe 11, and the waterproof effect is achieved again.

The automatic compensation mechanism 5 includes: a spring plate 51, a winding-shaped spring 53, a spring cover, and a mechanical reel 52. The spring plate 51 is open, and the spring plate 51 is detachably fixed near the nut 134 and can be fixed on the pipe 3 or the embedded pipe 11. A circular spring cavity is formed in the spring plate 51 and used for containing a spring 53 coiled into a circle, and a spring cover is detachably arranged at an opening of the spring plate 51 and used for sealing the opening of the spring plate 51, slowing down the aging of the spring 53 and blocking certain dust. The spiral spring 53 is made of a sheet steel strip and has certain restoring force, and when the spiral spring 53 is in a non-working state, the spiral spring 53 is naturally coiled in the spiral spring disc 51; when the power spring 53 is in an operating state, the mechanical winding shaft 52 winds up the power spring 53 onto the mechanical winding shaft 52. One end of the spring 53 is welded to the inner wall of the spring chamber and the other end of the spring 53 is welded to the mechanical spool 52. The mechanical winding shaft 52 is rotatably provided at the axial center of the spring plate 51 and penetrates the axial center of the spring plate 51. The mechanical reel 52 includes: the winding shaft 522 is connected to the center of one end of the center winding shaft 521, the nut 134 is connected to the center of one end of the center winding shaft 521, which is far away from the winding shaft 522, a winding groove 5211 for accommodating the winding spring 53 is formed in the circumferential surface of the center winding shaft 521, and the winding spring 53 can be wound on the center winding shaft 521 in order. The nut 134 barrel is cylindrical, a nut 134 hole which is the same as the nut 134 in shape is formed in one end, away from the central scroll 521, of the nut 134 barrel, the nut 134 hole is in clearance fit with the nut 134, the nut 134 hole wraps the nut 134, and the nut 134 barrel can be rotated to drive the nut 134 to rotate.

Firstly, manually rotating the winding handle 522 to wind the spiral spring 53 onto the mechanical winding shaft 52, and then directly loosening the hand, the spiral spring 53 will return to the original state, and the mechanical winding shaft 52 will start to rotate; after the clockwork spring 53 is wound, the nut 134 hole of the nut 134 cylinder is aligned with the nut 134, and the nut 134 is wrapped; the spring plate 51 is then fixed to the pipe 3 or the pre-buried pipe 11. It should be noted again that after the spring 53 is wound around the mechanical winding shaft 52, the rotation direction of the mechanical winding shaft 52, which is generated when the spring returns to the previous state, needs to be consistent with the direction in which the nut 134 moves to press the first clamping member 131 on the first threaded connecting member 133, so as to achieve the subsequent automatic compensation of the gap generated by the concrete shrinkage. When the concrete is not contracted, the elastic waterproof piece 12 is completely attached to the surfaces of the pipeline 3 and the embedded pipe 11, the nut 134 is in a state incapable of moving at the moment, the force of the restoring state of the spring 53 for driving the mechanical reel 52 to rotate is smaller than the force given to the nut 134 cylinder by the nut 134 and the elastic waterproof piece 12, so that the nut 134 cylinder cannot rotate, and the spring 53 continuously has a restoring force; when the concrete contracts or the elastic waterproof part 12 does not cling to the pipeline 3 and the embedded pipe 11 to form a gap due to other conditions, the spring 53 starts to separate from the mechanical reel 52, the mechanical reel 52 is driven to rotate, the nut 134 is driven to rotate by the nut 134, the nut 134 can move towards the second clamping part 132 along the axial direction of the first threaded connecting part 133, the first clamping part 131 is pushed to extrude the elastic waterproof part 12 until the elastic waterproof part 12 expands radially, the gap is blocked, the elastic waterproof part 12 clings to the pipeline 3 and the embedded pipe 11 again, and the waterproof effect is achieved again.

Example 4 the rest of the structure and the operation principle are the same as those of example 1.
