Background

With the development of cities, underground spaces of cities are more and more crowded, and underground pipelines such as electric power and the like are laid by adopting pipelines. However, due to improper maintenance, many spare power pipelines are often plugged by silt and need to be dredged before use. The current main pipe dredging method is to dredge by adopting a pipe penetrating device, the pipe penetrating device penetrates through a pipeline and then is tied with a hemp rope, and a reinforcing cage is dragged by the hemp rope to move in the pipeline, so that silt in the pipe is dragged out. The method can only dredge the blockage of the sediment accumulated in the pipeline, which is not a serious condition, and the pipelines which can be dredged are very limited. Therefore, the traditional pipeline dredging method is difficult to dredge the severely blocked power pipeline.

Referring to fig. 1 to 3, a pipeline dredging device 100 is provided in the present embodiment. The pipe pull 100 includes: a tube body 110, a helical spring head 120, and a drive spring 130.

One end of the helical spring head 120 is located inside the tube body 110 and rotatably connected to the tube body 110, and the other end extends out of the tube body 110. The coil spring head 120 is a conical coil spring. The drive spring 130 is located within the body 110. The drive spring 130 is rotatably coupled to the body 110. The drive spring 130 is capable of rotating the helical spring head 120 as it rotates.

When the above-described pipe line dredger 100 is used to dredge a pipe line, the pipe line dredger 100 is inserted into the pipe line. By rotating the drive spring 130, the drive spring 130 rotates, which causes the helical spring head 120 to rotate. The end of the helical spring head 120 that extends out of the tubular body 110 is used to dredge blockages in the pipeline. Because the helical spring head 120 is a conical helical spring, it has extrusion force and drilling force to the blockage in the pipeline when rotating, thereby easily loosening the blockage in the seriously blocked pipeline, and further facilitating to discharge the blockage out of the pipeline to dredge the pipeline.

Because the spiral spring head 120 is of a spring structure and has certain elasticity, hard objects can be avoided, and the spiral spring head is not easy to break and cannot damage the inner wall of the pipeline in the pipeline dredging process. Because the driving spring 130 is used as the driving part, when the pipeline is dredged, the blocking object (such as silt) in the pipeline can pass through the spring hole of the driving spring 130, so that the blocking object can be prevented from blocking the driving spring 130, and the rotation of the driving spring 130 is not easily influenced.

In one embodiment, the pitch of the helical spring head 120 decreases from the larger pitch to the smaller pitch in the direction of the helical spring head 120 extending to the tubular body 110.

Specifically, the helical spring head 120 extends to the extending direction of the pipe body 110, i.e., the direction in which the helical spring head 120 presses and drills the blockage when dredging the pipe. Because the pitch of the helical spring head 120 is reduced from large to small, the coils of the helical spring head 120 are thinned to be dense, so that the head of the helical spring head 120 is harder and firmer, and the helical spring head 120 has more strength during rotary drilling, thereby loosening the blockage more easily.

In one embodiment, the pipe pull 100 further comprises a bearing 140. The bearing 140 is located within the body 110. The outer ring of the bearing 140 is connected to the tube 110, and the inner ring of the bearing 140 is connected to the coil spring head 120 and the driving spring 130, respectively, so that the driving spring 130 rotates to drive the inner ring of the bearing 140 to rotate, and the inner ring of the bearing 140 drives the coil spring head 120 to rotate.

Specifically, the helical spring head 120 and the inner ring of the bearing 140 are fixed by spot welding, and the driving spring 130 and the inner ring of the bearing 140 are fixed by spot welding, so that the inner ring of the bearing 140, the helical spring head 120 and the driving spring 130 are reliably connected and are not easily loosened.

In one embodiment, the tubular body 110 includes a main body section 111 and a support tube section 112. The support tube segment 112 is fixedly connected to the main body segment 111. The drive spring 130 is located within the body section 111. Bearing 140 is located within support tube segment 112. The helical spring head 120 projects beyond the support tube section 112 in a direction away from the main body section 111.

Specifically, one end of the main body segment 111 is sleeved on the support tube segment 112. The pipe pull 100 further comprises a hoop 150. The hoop 150 is disposed at the connection position of the main body segment 111 and the supporting tube segment 112, and the main body segment 111 and the supporting tube segment 112 are fixed by the hoop 150.

Since the pipe body 110 can be divided into the main body section 111 and the support pipe section 112, the bearing 140 can be installed in the support pipe section 112, then the bearing 140 is fixed to the coil spring head 120 and the driving spring 130, and finally the support pipe section 112 is fixed to the main body section 111, thereby facilitating installation of the bearing 140, the coil spring head 120 and the driving spring 130.

Specifically, the bearing 140 may be disposed at an end of the support tube segment 112, thereby facilitating welding of the bearing 140 to the helical spring head 120 and the drive spring 130, respectively.

In one embodiment, the inner wall of the tube 110 is provided with a slot (not shown) extending along the circumference. The outer race of the bearing 140 mates with the snap groove.

Specifically, the outer ring of the bearing 140 is disposed in and engaged with the locking groove, so that the bearing 140 is connected to the pipe body 110.

In this embodiment, the locking groove is formed on the inner wall of the support tube 112, so that the bearing 140 is connected to the inner wall of the support tube 112 after the outer ring of the bearing 140 is engaged with the locking groove.

In one embodiment, the number of bearings 140 is two and the two bearings 140 are spaced apart.

Specifically, two bearings 140 are located at each end of the support tube segment 112. Because the two bearings 140 are arranged at intervals, the two bearings 140 are connected with the helical spring head 120 and the driving spring 130, so that the moving path is stable when the helical spring head 120 and the driving spring 130 rotate, and the helical spring head and the driving spring are not easy to shake along the radial direction.

In one embodiment, the support tube segment 112 is formed from a material having a hardness greater than the hardness of the material of the body segment 111.

In particular, the material used to support the spool piece 112 may be a metal, such as stainless steel, copper, iron, and the like. The material used for the main body segment 111 may be plastic, such as PVC plastic, PE plastic.

Since the material of the support tube segment 112 has a hardness greater than that of the material of the body segment 111, the support tube segment 112 can more reliably support the helical spring head 120 and the drive spring 130.

Because the hardness of the material of the main body section 111 is relatively low, the main body section 111 is easy to bend along with the trend of the power pipeline, and the pipeline dredging device 100 is convenient to dredge the bent power pipeline.

In one embodiment, the drain pull 100 further comprises a motor (not shown). The motor is used to drive the driving spring 130 to rotate, thereby driving the helical spring head to rotate.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
