Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging equipment technology, and more specifically, to a spiral propulsion pipeline cleaning device for dredging blocked pipelines. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. During use, dirt easily accumulates on pipelines, causing poor flow of the medium or even blockage. In order to avoid affecting pipeline transportation, the inner wall of the pipeline needs to be cleaned regularly.

[0003] Chinese patent CN209238623U discloses a spiral pipe cleaner that solves the problem that existing tools used for cleaning the flue pipes of phase change vacuum heating furnaces are not suitable, resulting in incomplete cleaning and easy damage to the flue pipes. However, this pipe cleaner can only unclog pipes with a fixed inner diameter. When the inner diameter of the pipe is large or small, the spiral head at the end cannot effectively scrape off the dirt attached to the inner wall of the pipe or cannot penetrate into the pipe, resulting in poor applicability of the pipe cleaner. Utility Model Content

[0004] This invention provides a spiral propulsion pipe cleaning tool for unblocking pipes, which solves the technical problem that existing pipe cleaning tools can only unblock pipes with a fixed inner diameter and have poor applicability.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A spiral propulsion pipe cleaner for unblocking pipes includes a top plate. A first threaded sleeve is fixedly connected to the middle of the top plate. A first screw is threadedly connected to the inside of the first threaded sleeve. A connecting plate is fixedly connected to one end of the first screw. A second screw is fixedly connected to the connecting plate. A propulsion head is fixedly connected to the end of the second screw. A set of movable plates is provided between the connecting plate and the propulsion head. A second threaded sleeve is rotatably connected to the middle of the movable plate via a bearing. The second threaded sleeve is threaded onto the outer surface of the second screw. The surface of the propulsion head has several sets of sliding grooves. A sliding strip is slidably arranged inside each of the several sets of sliding grooves. The front end of the sliding strip extends out of the outside of the sliding groove and is fixedly connected to a cleaning scraper. A connecting rod is provided between the rear end of the sliding strip and the movable plate. The two ends of the connecting rod are respectively hinged between the rear end of the sliding strip and the movable plate.

[0007] Furthermore, an air bladder is provided on one side of the top plate, which is nested in the surface of the first threaded sleeve, and a connector is provided on the air bladder that passes through the top plate.

[0008] Furthermore, a rotating rod is fixedly connected to the end of the first screw away from the connecting plate, and a handle is provided at the end of the rotating rod.

[0009] Furthermore, a hexagonal head is fixedly fitted onto the outer surface of the second threaded sleeve.

[0010] Furthermore, the front end of the propulsion head has a conical structure.

[0011] Furthermore, the outer surface of the cleaning blade has an arc-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the second screw sleeve on the second screw, the cleaning scrapers at the front end of several sets of slide bars can move simultaneously toward the inside or outside of the push head, thereby enabling the cleaning scrapers around the push head to fit against the inner wall of pipes with different inner diameters. When the push head extends from one end of the pipe and the top plate is pressed and fixed against the end of the pipe, rotating the first screw can drive the push head and the cleaning scrapers around it to rotate and advance toward the inside of the pipe, so that the pig can clean the dirt attached to the inner wall of pipes with different inner diameters, effectively improving the applicability of the pig.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A spiral propulsion pipe cleaning device for unblocking pipes includes a top plate 1. A first screw sleeve 2 is fixedly connected to the middle of the top plate 1. A first screw rod 3 is threadedly connected to the inside of the first screw sleeve 2. When the top plate 1 is fixed to the end of the pipe, rotating the first screw rod 3 causes it to rotate under the driving action of the first screw sleeve 2 and advance into the pipe. A connecting plate 4 is fixedly connected to one end of the first screw rod 3. A second screw rod 5 is fixedly connected to the connecting plate 4. A propulsion head 6 is fixedly connected to the end of the second screw rod 5. A set of movable plates 7 is provided between the connecting plate 4 and the propulsion head 6. A second screw sleeve 8 is rotatably connected to the middle of the movable plate 7 via a bearing. The second screw sleeve 8 is threaded onto the outer surface of the second screw rod 5. When the second screw sleeve 8 on the outer surface of the second screw rod 5 is rotated, the second screw sleeve 8 can drive the movable plate 7 to move closer to or away from the propulsion head 6. The surface of the propulsion head 6 has several... The dry chute 9 has several sets of sliding strips 10 slidably installed inside each set of chute 9. The front end of each sliding strip 10 extends out of the outside of the chute 9 and is fixedly connected to a cleaning scraper 11. A connecting rod 12 is provided between the rear end of each sliding strip 10 and the movable plate 7. The two ends of the connecting rod 12 are respectively hinged between the rear end of each sliding strip 10 and the movable plate 7. When the movable plate 7 moves towards the push head 6, the several sets of sliding strips 10 will slide towards the outside of the chute 9 simultaneously under the pushing action of the connecting rod 12. At this time, the cleaning scrapers 11 at the front end of each set of sliding strips 10 will move towards the outside of the push head 6 simultaneously under the action of the connecting rod 12. Conversely, when the movable plate 7 moves away from the push head 6, the several sets of sliding strips 10 will slide towards the inside of the chute 9 simultaneously under the pulling action of the connecting rod 12. At this time, the cleaning scrapers 11 at the front end of each set of sliding strips 10 will move towards the inside of the push head 6 simultaneously under the action of the connecting rod 12.

[0022] In use, rotating the second screw sleeve 8 moves the movable plate 7 towards or away from the push head 6, causing the cleaning scrapers 11 at the front ends of several sets of slide bars 10 to move simultaneously towards the inside or outside of the push head 6. This allows the cleaning scrapers 11 at the front ends of several sets of slide bars 10 to conform to the inner walls of pipes with different inner diameters. When the push head 6 extends into the pipe from one end, it presses and fixes the top plate 1 against the end of the pipe. Rotating the first screw 3 causes it to move towards the inside of the pipe under the drive of the first screw sleeve 2. During this process, the push head 6 rotates and pushes into the pipe, conforming to the inner walls of pipes with different inner diameters. Several sets of cleaning scrapers 11 attached to the inner wall surface of the pipe also rotate and advance towards the inside of the pipe along with the push head 6. The several sets of cleaning scrapers 11 can scrape off the dirt attached to the inner wall of the pipe, effectively cleaning the inner wall of the pipe. As can be seen from the above, since the cleaning scrapers 11 at the ends of several sets of slide bars 10 can be controlled to move simultaneously towards the outside or inside of the push head 6, the cleaning scrapers 11 can fit against the inner wall of pipes with different inner diameters when the push head 6 is inserted into the pipe. Therefore, the pipe cleaner can clean the dirt attached to the inner wall of pipes with different inner diameters, effectively improving the applicability of the pipe cleaner.

[0023] For further details, please refer to Figure 1-4 An air bladder 13 is nested on the surface of the first threaded sleeve 2 on one side of the top plate 1. A connector 14 is provided on the air bladder 13 that passes through the top plate 1. When the push head 6 is inserted into the pipe and the top plate 1 is pressed against one end of the pipe, the air pump can be connected to the connector 14 and the air bladder 13 can be inflated, causing the air bladder 13 to expand outward and abut against the inner wall of the pipe end. At this time, the frictional resistance generated between the air bladder 13 and the inside of the pipe can keep the top plate 1 and the pipe fixed. After the pipe is cleared, the air inside the air bladder 13 is extracted by the air pump, and the push head 6 can be moved out of the outside of the pipe.

[0024] For further details, please refer to Figure 1-4 The first screw 3 is fixedly connected to a rotating rod 15 at the end away from the connecting plate 4. A handle 16 is provided at the end of the rotating rod 15. The user can easily control the first screw 3 to rotate by holding the handle 16.

[0025] For further details, please refer to Figure 1-4 The outer surface of the second threaded sleeve 8 is fixedly fitted with a hexagonal head 17. The user can use tools such as a wrench to hold the hexagonal head 17, which makes it easy to turn the second threaded sleeve 8 to rotate.

[0026] For further details, please refer to Figure 1-4 The front end of the propulsion head 6 is a conical structure, which reduces the resistance caused by blockages when the propulsion head 6 is pushed forward inside the pipe.

[0027] For further details, please refer to Figure 1-4The outer surface of the cleaning scraper 11 is an arc-shaped structure. The arc-shaped outer surface of the cleaning scraper 11 is relatively smooth and has no sharp edges. It can fit closely with the inner wall of the pipe and is not easy to scratch the inner wall of the pipe when moving.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
