Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, and specifically relates to a hand-cranked pipeline dredger. Background Technique

[0002] A hand-cranked pipeline dredger is a tool used to clean and dredge blocked pipelines. It mainly achieves the removal of blockages through manual operation. The user needs to insert the dredging head into the blocked pipeline and then rotate the crank handle, causing the dredging head to rotate and advance in the pipeline. As the dredging head goes deeper, it will come into contact with the blockage and attempt to break or push it. Through repeated operations, the user can gradually remove the blockage in the pipeline and restore the normal drainage function of the pipeline.

[0003] However, most of the hand-cranked dredgers in the traditional method are rotational movements, which are relatively single. And when the length of the flexible shaft is not enough to reach the blocked position, it is difficult to achieve a good dredging effect. Content of the Utility Model

[0007] To achieve the above purpose, the utility model provides the following technical solution: A hand-cranked pipeline dredger includes a main pipeline. A flexible shaft is arranged inside the main pipeline, and a conical spiral spring for cleaning blockages in the pipeline is fixedly connected to the lower end of the flexible shaft;

[0008] A blockage cleaning power component is arranged on the main pipeline. The blockage cleaning power component is used to provide the movement power during blockage cleaning. The blockage cleaning power component includes a hexagonal transmission shaft, a gear disk, a hexagonal sliding cylinder, a sliding ring, a sliding column, a first gear, a movable gear, a connecting rod, and a movable sleeve;

[0009] The hexagonal transmission shaft in the blockage cleaning power component is rotatably connected inside the main pipeline. The hexagonal sliding cylinder is slidably sleeved on the outer surface of the hexagonal transmission shaft, and the upper end of the flexible shaft is fixedly connected to the lower end of the hexagonal sliding cylinder;

[0010] The gear disk is fixedly sleeved on the upper end of the hexagonal transmission shaft. The first gear is rotatably connected to the outer surface of the main pipeline. A handle is rotatably connected to the outer edge position of the first gear. The first gear is meshed with the gear disk. A fixing frame is fixedly connected to the outer surface of the main pipeline, and a fixing shaft is arranged on the surface of the main pipeline.

[0011] Preferably, the fixed shaft is fixedly connected between the main pipe and the fixed frame. The movable gear is sleeved on the outer surface of the fixed shaft, and a movable sleeve is slidably connected to the outer surface of the fixed frame.

[0012] Preferably, the movable gear is located in the groove on the movable sleeve. The movable sleeve is used to control the meshing of the movable gear with the second gear and the first gear. A handheld frame is fixedly connected to the outer surface of the main pipe.

[0013] Preferably, a second gear is rotatably connected to the outer surface of the main pipe. The movable gear is respectively meshed and connected with the first gear and the second gear.

[0015] Preferably, the sliding column is fixedly connected to the sliding ring. The sliding column is slidably connected to the inner wall of the circumferential groove. The lower end of the connecting rod is rotatably connected to the sliding column.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present utility model provides a hand-cranked pipe dredger, which has the following

[0018] beneficial effects:

[0019] 1. For this hand-cranked pipe dredger, by controlling the inward sliding of the movable sleeve, the movable sleeve can drive the movable gear to mesh with the first gear and the second gear. At this time, the second gear can be driven to rotate. The rotating second gear can drive the connecting rod to operate together. Thus, the sliding ring is driven to move up and down by the sliding column at the lower end of the connecting rod. When the sliding ring moves up and down, the sliding column in the circumferential groove can drive the hexagonal sliding cylinder to continuously reciprocate along the sliding direction of the hexagonal transmission shaft. The reciprocating hexagonal sliding cylinder can continuously pull and draw the flexible shaft in the pipe to be dredged, so that the fluid in the pipe can have a certain impact force. This impact force is similar to the water hammer effect and can be conducted along the pipe until it acts on the blockage position, causing a certain impact on the blockage position. Therefore, the dredging effect of the blocked pipe can be improved to a certain extent, avoiding the problem that the movement of the hand-cranked dredger in the traditional method is relatively single, and when the length of the flexible shaft is not enough to reach the blockage position, it is difficult to achieve a good dredging effect.

[0020] 2. The hand-operated pipe dredger can screw and hold the sundries blocked in the pipe with the conical spiral spring on the flexible shaft when the flexible shaft rotates. When the user feels the resistance of the conical spiral spring screwing and holding the sundries, the flexible shaft is pulled out, so that the sundries screwed on the conical spiral spring are taken out together, thus completing the dredging of the pipe. This dredging method improves the convenience of pipe dredging, enabling even users without operation experience to easily get started. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-3 , the present invention provides a new technical solution: a hand-operated pipe dredger, including a main pipe 1, a flexible shaft 2 is arranged in the main pipe 1, and a conical spiral spring for cleaning the blockage in the pipe is fixedly connected to the lower end of the flexible shaft 2;

[0027] A clog-removing power assembly is arranged on the main pipe 1, and the clog-removing power assembly is used to provide the movement power during clog removal. The clog-removing power assembly includes a hexagonal transmission shaft 3, a gear disc 4, a hexagonal sliding cylinder 5, a sliding ring 6, a sliding column 8, a first gear 9, a movable gear 12, a connecting rod 14 and a movable sleeve 16;

[0028] The hexagonal transmission shaft 3 in the clog-removing power assembly is rotatably connected in the main pipe 1, the hexagonal sliding cylinder 5 is slidably sleeved on the outer surface of the hexagonal transmission shaft 3, and the upper end of the flexible shaft 2 is fixedly connected to the lower end of the hexagonal sliding cylinder 5;

[0029] The gear disk 4 is fixedly sleeved on the upper end of the hexagonal transmission shaft 3. The first gear 9 is rotatably connected to the outer surface of the main pipe 1. A handle 10 is rotatably connected to the outer edge position of the first gear 9. The first gear 9 is meshed and connected with the gear disk 4. A fixing frame 15 is fixedly connected to the outer surface of the main pipe 1, and a fixing shaft 11 is arranged on the surface of the main pipe 1.

[0030] Furthermore, the fixing shaft 11 is fixedly connected between the main pipe 1 and the fixing frame 15. The movable gear 12 is sleeved on the outer surface of the fixing shaft 11. A movable sleeve 16 is slidably connected to the outer surface of the fixing frame 15.

[0031] Furthermore, the movable gear 12 is located in the groove on the movable sleeve 16. The movable sleeve 16 is used to control the meshing of the movable gear 12 with the second gear 13 and the first gear 9. A hand-held frame 17 is fixedly connected to the outer surface of the main pipe 1.

[0032] Furthermore, a second gear 13 is rotatably connected to the outer surface of the main pipe 1. The movable gear 12 is meshed and connected with the first gear 9 and the second gear 13 respectively. A connecting rod 14 is rotatably connected to the edge position of the second gear 13. The second gear 13 is used to drive the hexagonal sliding cylinder 5 to reciprocate up and down.

[0033] Furthermore, a circumferential groove 7 is formed on the outer surface of the hexagonal sliding cylinder 5. A sliding ring 6 is slidably sleeved on the outer surface of the main pipe 1. A kidney-shaped sliding groove adapted to the sliding column 8 is formed on the outer surface of the main pipe 1.

[0034] Furthermore, the sliding column 8 is fixedly connected to the sliding ring 6. The sliding column 8 is slidably connected to the inner wall of the circumferential groove 7. The lower end of the connecting rod 14 is rotatably connected to the sliding column 8.

[0035] Furthermore, in use, the conical spiral spring on the flexible shaft 2 is inserted into the pipe to be dredged. Then, by manually rotating the handle 10, when the handle 10 drives the first gear 9 to rotate, it can drive the gear disk 4 and the hexagonal transmission shaft 3 thereon to rotate. When the hexagonal transmission shaft 3 rotates, it can drive the flexible shaft 2 to rotate through the hexagonal sliding cylinder 5. When the flexible shaft 2 rotates, the conical spiral spring thereon can twist the sundries blocked in the pipe. When the user feels the resistance of the conical spiral spring twisting the sundries, the flexible shaft 2 is pulled out, so that the sundries screwed on the conical spiral spring are taken out together, thereby completing the dredging of the pipe. This dredging method improves the convenience of pipe dredging, enabling even users without operation experience to easily get started.

[0036] Furthermore, when the handle 10 drives the first gear 9 to rotate, the movable sleeve 16 is controlled to slide inward, so that the movable sleeve 16 can drive the movable gear 12 to mesh with the first gear 9 and the second gear 13. At this time, the second gear 13 can be driven to rotate, and the rotating second gear 13 can drive the connecting rod 14 to operate together. Thus, the sliding column 8 at the lower end of the connecting rod 14 drives the sliding ring 6 to move up and down. When the sliding ring 6 moves up and down, the sliding column 8 in the circumferential groove 7 drives the hexagonal sliding cylinder 5 to continuously reciprocate along the sliding direction of the hexagonal transmission shaft 3. The reciprocating hexagonal sliding cylinder 5 can continuously pull and draw the flexible shaft 2 in the pipeline to be dredged, so that the fluid in the pipeline can have a certain impact force. This impact force is similar to the water hammer effect and can be conducted along the pipeline until it acts on the blockage position, causing a certain impact on the blockage position, thereby improving the dredging effect of the blocked pipeline to a certain extent, avoiding the problem that the traditional hand-operated dredger has a relatively single movement and it is difficult to achieve a good dredging effect when the length of the flexible shaft 2 is not enough to reach the blockage position.

[0037] Working principle: During use, the conical spiral spring on the flexible shaft 2 is inserted into the pipeline to be dredged. Then, by turning the hand crank 10, when the handle 10 drives the first gear 9 to rotate, it can drive the gear disc 4 and the hexagonal transmission shaft 3 thereon to rotate. When the hexagonal transmission shaft 3 rotates, it can drive the flexible shaft 2 to rotate through the hexagonal sliding cylinder 5. When the flexible shaft 2 rotates, the conical spiral spring thereon can twist and hold the sundries blocked in the pipeline. When the user feels the resistance of the conical spiral spring twisting the sundries, the flexible shaft 2 is pulled out, so that the sundries twisted on the conical spiral spring are taken out together, thus completing the dredging of the pipeline.

[0038] Furthermore, when the handle 10 drives the first gear 9 to rotate, the movable sleeve 16 is controlled to slide inward, so that the movable sleeve 16 can drive the movable gear 12 to mesh with the first gear 9 and the second gear 13. At this time, the second gear 13 can be driven to rotate, and the rotating second gear 13 can drive the connecting rod 14 to operate together. Thus, the sliding column 8 at the lower end of the connecting rod 14 drives the sliding ring 6 to move up and down. When the sliding ring 6 moves up and down, the sliding column 8 in the circumferential groove 7 drives the hexagonal sliding cylinder 5 to continuously reciprocate along the sliding direction of the hexagonal transmission shaft 3. The reciprocating hexagonal sliding cylinder 5 can continuously pull and draw the flexible shaft 2 in the pipeline to be dredged, so that the fluid in the pipeline can have a certain impact force. This impact force is similar to the water hammer effect and can be conducted along the pipeline until it acts on the blockage position, causing a certain impact on the blockage position, thereby improving the dredging effect of the blocked pipeline to a certain extent.

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
