Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, in particular to a drainage pipeline dredging device. Background Art

[0002] During the construction process, such as residential building projects that are in the decoration stage, some construction waste is often generated during the construction process, such as sand, cement, stones, PVC glue, plastic bags, rags and other construction waste. However, these construction wastes are likely to enter the drainage pipes through floor drains or inspection ports, causing pipe blockages.

[0003] During the construction process, for unclogging drainage pipes, workers generally take a relatively simple method to unblock the pipes, such as using easily available sticks or steel chisels to reach into the drainage pipes to clear the blockages, but this method is not clean enough, and will be affected by the length of the stick or steel chisel, and it is difficult to complete the unblocking work when the drainage pipe has a curved part; in addition, for unclogging pipes, there are also methods of using "motor + manganese steel spring + drill bit", "manual rocker + steel chisel + drill bit", "steel belt + impact head", "manual remote control lever + manganese steel spring" and other types of tools, but these tools have the disadvantages of high consumption rate, destructiveness, and being not conducive to the protection of finished products, and are not suitable for the construction environment on site during the construction process of the building project. Therefore, the existing technology often cannot safely and effectively unblock the floor pipes. Utility Model Content

[0004] In order to overcome the problems that the existing technology cannot clean the drainage pipes thoroughly and is affected by the length of the stick or steel chisel, or the cleaning tools used have high consumption rate and are destructive, and cannot be cleaned safely and effectively, the embodiment of the utility model provides a drainage pipe unclogging device. The technical solution is as follows:

[0005] A drainage pipe dredging device comprises a cleaning piece which can slide closely against the inner wall of the pipe and a pull rope arranged on the side of the cleaning piece.

[0006] Furthermore, the pull ropes are arranged on both side surfaces of the cleaning piece.

[0007] Furthermore, a connecting rod is passed through the center of the cleaning piece and is axially fixed thereto, one end of the connecting rod is fixedly connected to the pull rope, and the other end of the connecting rod is threadedly connected to a nut. The cleaning piece is connected to the pull rope through the connecting rod and is fixed by the nut, thereby facilitating replacement of cleaning pieces of different forms to cope with different blockage situations.

[0008] Furthermore, one end of the connecting rod close to the pull rope is threadedly connected to a connecting tube, the other end of the connecting tube is fixedly connected to the pull rope, and the connecting tube is threadedly connected to the connecting rod, which is convenient for replacing the pull rope or the connecting rod at a later time.

[0009] Furthermore, the cleaning piece is an arc-shaped plate, the cross-section of the arc-shaped plate is circular and the diameter of the largest cross-sectional circle is equal to the inner diameter of the pipe, the side of the arc-shaped plate close to the pull rope is concave from the edge to the center to form an arc-shaped groove, and the other side of the arc-shaped plate protrudes outward to form an arc surface, and the arc-shaped groove can temporarily store blockages when clearing the pipe, making it convenient for the cleaning piece to take it out of the pipe.

[0010] Furthermore, the cleaning piece is a conical plate, the cross-section of the conical plate is circular and the diameter of the largest cross-sectional circle is equal to the inner diameter of the pipe, the center of one side of the conical plate close to the pull rope protrudes outward to form a conical surface and is concave from the edge to the center to form an arc groove, and the other side of the conical plate protrudes outward to form an arc surface, and the conical surface is conducive to crushing the solidified concrete blocks in the pipe, thereby temporarily storing them in the arc groove so as to be taken out of the pipe.

[0011] Furthermore, the cleaning piece is a mesh plate, the cross-section of the mesh plate is circular and the diameter of the largest cross-sectional circle is equal to the inner diameter of the pipe, and a plurality of through holes are opened on the mesh plate along the length direction of the connecting rod, and the through holes can disperse the large pieces of PVC glue blocking the pipe into several pieces, so as to facilitate the use of the curved plate to clean it out of the pipe again, avoiding the problem of being difficult to clean because the whole piece is squeezed in the pipe.

[0012] Furthermore, the pull rope is a steel wire rope, which is wear-resistant and not easy to break and is easy to fix to the connecting tube.

[0013] Furthermore, the cleaning piece is made of a thin steel plate.

[0014] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device has a simple structure and is easy to use, and can flexibly select a suitable cleaning piece to perform cleaning work according to the specific situation of the blockage in the drainage pipe at the construction site, and can safely and effectively clean the blockage and dredge the pipe;

[0015] The device adopts the form of combining a flexible steel wire rope with a rigid connecting rod and a rigid cleaning piece, so that the cleaning piece can always move close to the inner wall of the pipeline, thereby improving the effect of pipeline dredging and cleaning.
