Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning equipment technology, specifically an intelligent pipeline dredging device. Background Technology

[0002] During long-term oil pipeline transportation, impurities such as sludge and wax accumulate on the inner wall. These deposits gradually thicken, leading to a reduction in pipe diameter and increased transportation resistance, severely impacting crude oil transportation efficiency. Currently, the industry commonly uses dredging equipment with a constant-pitch helical propulsion structure. This design has two drawbacks in practical applications: First, due to varying degrees of corrosion and deformation after long-term use, the rigid helical blades of traditional equipment cannot adapt to the irregular pipe wall shape, making it difficult to thoroughly remove deposits from corrosion depressions. In particular, the rough pipe wall in corrosion areas is more prone to sludge and other substances accumulating. Second, during long-distance dredging operations, the constant-pitch design easily causes sludge to re-accumulate during transportation, especially forming blockages near the pipe wall, forcing frequent interruptions for manual cleaning and significantly reducing work efficiency.

[0003] Therefore, we propose an intelligent pipeline dredging device. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] A smart pipeline dredging device includes a propulsion mechanism, which includes a propulsion platform that moves back and forth. The propulsion platform is equipped with a rotating unit for driving a connector to rotate. The connector is used to drive a front-end auger propulsion unit and a rear-end auger sludge discharge unit to rotate for cleaning the inside of the pipeline. The front-end auger propulsion unit includes a front-end rotating tube with front-end spiral blades equidistantly arranged on it. A compensation structure for cleaning corrosion in the pipe is provided on the front-end spiral blades near the head. The compensation structure includes multiple cavities, which are opened in the front-end spiral blades. A telescopic plate is slidably connected in the cavity, and an elastic sheet is provided in the cavity. The telescopic plate and the elastic sheet are fixedly connected. The elastic sheet uses its own elastic force to make the telescopic plate slide and then return to its original position. A filling component is provided between adjacent telescopic plates. The rear-end auger sludge removal unit includes a rear-end rotating pipe with rear-end spiral blades evenly spaced on it. The pitch between the rear-end spiral blades is smaller than the pitch of the front-end spiral blades.

[0006] Preferably, the forward end of the front rotating tube is provided with a triangular protruding cone, and a guide groove is provided in the cavity. The elastic sheet is slidably connected in the guide groove, and a guide rod slides through the middle of the elastic sheet to guide the sliding of the elastic sheet. A return spring is nested on the guide rod, and the two ends of the return spring abut against the elastic sheet and the inner wall of the cavity, respectively.

[0007] Preferably, the filling component includes a baffle plate, which is slidably connected to one side of the telescopic plate. A sliding rod is fixedly connected to the side of the baffle plate near the telescopic plate. The other end of the sliding rod is slidably inserted into the interior of the telescopic plate. A retaining spring is nested on the sliding rod, which fixes the baffle plate and the telescopic plate in place. The end of the baffle plate near the front spiral blade has an arc-shaped surface, and adjacent baffle plates are staggered.

[0008] Preferably, the rotating unit includes a housing, which is mounted on the push platform. A hydraulic motor is fixedly connected to the back of the housing. A first gear is provided inside the housing and is driven by the hydraulic motor. A second gear meshes below the first gear. A central shaft is connected to the middle of the second gear through tooth rotation. A connector is fixedly connected to the central shaft. The hydraulic motor is driven by a hydraulic station.

[0009] Preferably, a drive motor is fixedly connected to both sides of the housing, and the drive motor drives the gear and rack to mesh and transmit power, so that the housing moves, and the rack is fixedly connected to the push platform.

[0010] Preferably, the front-end auger propulsion unit and the rear-end auger sludge discharge unit are detachably connected by a connecting unit. The connecting unit includes a rear connecting component, which includes a rear connecting column. The rear connecting column has a hexagonal prism shape on its exterior and is located at the tail end of the front-end auger propulsion unit and the rear-end auger sludge discharge unit. A rectangular connecting seat is fixedly connected inside the rear connecting column. A connecting cavity is provided on the rectangular connecting seat. A through rear screw hole is provided on the rear connecting column and the rectangular connecting seat.

[0011] Preferably, the connecting unit further includes a front connecting component, which includes a front connecting post.

The other end of the steel wire rope is fixedly connected to a rectangular connecting seat at the tail of the front rotating tube. In the rear rotating tube, a steel wire rope is fixedly connected between the rectangular connecting block and the rectangular connecting seat. A hydraulic winch is provided at the tail of the push platform. By connecting the steel wire rope and the hydraulic winch, multiple steel wire ropes connected in series pull the steel disc to pull the fractured parts out of the pipe.

[0013] Preferably, the rear end of the central shaft is provided with a lubrication and cooling unit, which includes a drainage channel. The drainage channel is located inside the central shaft and is connected to a water tank through a water guide pipe. Water is supplied to the drainage channel by a water pump in the water tank.

[0014] The beneficial effects of this invention are: This invention employs a variable pitch design with a larger front pitch and a smaller rear pitch. The front section rapidly transports sludge, improving transport efficiency. The rear section, with its closely arranged rear helical blades, increases the relative speed between the blades and the sludge, disrupting the gelled structure of the sludge and improving transport smoothness. Secondly, the compensation structure on the front helical blades automatically adapts to the unevenness of the pipe's inner wall, ensuring that sludge in corroded areas is thoroughly cleaned. Furthermore, the built-in steel wire rope connects multiple sludge removal units in series, enabling the recovery of broken components and improving operational reliability.

[0018] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] Example: like Figures 1-13 As shown, an intelligent pipeline dredging device includes a propulsion mechanism 1, which includes a propulsion platform 11 that moves back and forth. The propulsion platform 11 is provided with a rotating unit 12 for driving a connector 16 to rotate. The connector 16 is used to drive the front end auger propulsion unit 4 and the rear end auger sludge discharge unit 5 to rotate for cleaning the inside of the pipeline 100. The front-end auger propulsion unit 4 includes a front-end rotating tube 41, on which front-end spiral blades 43 are equidistantly arranged. The front-end spiral blades 43 near the head are provided with a compensation structure 44 for cleaning corrosion on the pipe 100. The compensation structure 44 includes multiple cavities 442, which are opened in the front-end spiral blades 43. A telescopic plate 441 is slidably connected in the cavity 442. An elastic sheet 443 is provided in the cavity 442. The telescopic plate 441 and the elastic sheet 443 are fixedly connected. The elastic sheet 443 uses its own elasticity to make the telescopic plate 441 slide and then return to its original position. A filling component 447 is provided between adjacent telescopic plates 441. The rear-end auger sludge removal unit 5 includes a rear-end rotating pipe 51, on which rear-end spiral blades 52 are evenly spaced. The pitch between the rear-end spiral blades 52 is smaller than the pitch of the front-end spiral blades 43. In traditional constant-pitch conveying, sludge re-gels in low-speed zones (such as near the pipe wall, close to the inner wall of the pipe 100), leading to adhesion and accumulation, causing blockage. In this application, the pitch of the rear-end spiral blades 52 of the rear-end rotating pipe 51 is reduced, thereby increasing the relative speed between the rear-end spiral blades 52 and the sludge (the smaller pitch has a higher shear rate at the same rotation speed), which disrupts the gelation structure of the sludge and improves the smoothness of conveying. At the same time, the pitch of the front-end spiral blades 43 of the front-end rotating pipe 41 is increased, thereby improving the conveying efficiency.

[0020] The front end of the rotating tube 41 is provided with a triangular protruding cone 42, and a guide groove 444 is provided in the cavity 442. The elastic sheet 443 is slidably connected in the guide groove 444. A guide rod 445 slides through the middle of the elastic sheet 443 to guide the sliding of the elastic sheet 443. A return spring 446 is nested on the guide rod 445. The two ends of the return spring 446 abut against the elastic sheet 443 and the inner wall of the cavity 442, respectively. The rotating unit 12 includes a housing 121, which is mounted on the push platform 11. A hydraulic motor 122 is fixedly connected to the back of the housing 121. A first gear 123 is installed inside the housing 121 and is driven by the hydraulic motor 122. A second gear 124 meshes below the first gear 123. A central shaft 125 is rotatably connected to the middle of the second gear 124 via teeth. A connector 16 is fixedly connected to the central shaft 125. The hydraulic motor 122 is powered by a hydraulic station 15. Drive; Hydraulic station 15 drives hydraulic motor 122 to work. After hydraulic motor 122 works, it drives gear 123 to rotate. Gear 123 drives gear 124 to rotate through meshing. Gear 124 drives central shaft 125 to rotate through teeth. The front end of central shaft 125 is connected to connector 16 through connector. Connector 16 and rear connecting column 611 are adapted and engaged. When connector 16 rotates, it drives front auger propulsion unit 4 and rear auger sludge discharge unit 5 to rotate. Drive motors 13 are fixedly connected to both sides of the housing 121. Drive motors 13 drive gears and racks 14 to mesh and transmit power, causing the housing 121 to move. The racks 14 are fixedly connected to the push platform 11. After the drive motors 13 work, they drive the gears to rotate. The gears and racks 14 mesh with each other, causing the housing 121 to move back and forth on the racks 14 (the direction of movement of the housing 121 is determined by the rotation direction of the drive motors 13).

[0021] In this embodiment, the pipe 100 to be cleaned is first placed on the bracket. Then, the robotic arm is operated to grab the front auger propulsion unit 4. The front auger propulsion unit 4 is the first structure to enter the pipe 100. The tail of the front rotating tube 41 in the front auger propulsion unit 4 is connected to the connector 16. Then, the rotating unit 12 is operated to drive the front rotating tube 41 to rotate. At the same time, the drive motor 13 is used to drive the front rotating tube 41 to approach the pipe 100. First, the triangular protruding cone 42 enters the interior of the pipe 100. The rotating triangular protruding cone 42 can break up larger deposits inside the pipe 100. At the same time, the front spiral blade 43 on the front rotating tube 41 rotates along with it. The rotating front spiral blade 43 adheres to the inner wall of the pipe 100, further breaking up the deposits on the inner wall of the pipe 100. At the same time, the rotating front spiral blade 43 and the inner wall of the pipe 100 cooperate to allow the broken deposits to be conveyed out of the pipe 100 by the front spiral blade 43, completing the internal cleaning of the pipe 100.

[0022] It is important to understand that corrosion can occur in some areas inside the pipe 100, resulting in an irregular circular cross-section. This prevents the front rotating tube 41 from cleaning the irregular areas when it drives the front spiral blade 43 to rotate. Therefore, in this application, the front spiral blade 43 is equipped with multiple telescopic plates 441. When the front rotating tube 41 is inside the pipe 100, the telescopic plates 441 are always in contact with the inner wall of the pipe 100 under the elastic action of the elastic sheet 443. When the inner wall of the pipe 100 is concave, the telescopic plates 441 slide outward under the elastic action of the elastic sheet 443, allowing the end of the telescopic plates 441 to extend into the bottom of the concave area and clean the deposits attached to the bottom of the concave surface. When the inner wall of the pipe 100 is convex, the telescopic plates 441 slide inward into the front spiral blade 43 under the elastic action of the elastic sheet 443, and the elastic sheet 443 is compressed, allowing the front spiral blade 43 to pass through the convex part inside the pipe 100. Meanwhile, the guide groove 444 and the guide rod 445 are used to guide the deformation direction of the elastic sheet 443, and the return spring 446 can play an auxiliary reset function when the elastic sheet 443 deforms.

[0023] Therefore, when cleaning the pipe 100, this application can also take into account the corroded areas inside the pipe 100, because the inner wall of the pipe in the corroded area is not smooth and is more likely to cause the accumulation of impurities. Therefore, it needs to be given special attention to improve the cleaning effect of the pipe 100.

[0024] like Figures 8-11 As shown, the filling assembly 447 includes a baffle plate 4471, which is slidably connected to one side of the telescopic plate 441. A sliding rod 4474 is fixedly connected to the side of the baffle plate 4471 near the telescopic plate 441. The other end of the sliding rod 4474 is slidably inserted into the interior of the telescopic plate 441. A retaining spring 4473 is nested on the sliding rod 4474. The retaining spring 4473 fixes the baffle plate 4471 and the telescopic plate 441. An arc-shaped surface 4472 is provided at the end of the baffle plate 4471 near the front spiral blade 43. Two adjacent baffle plates 4471 are staggered.

[0025] In this embodiment, the baffle plate 4471 serves to fill the gap between adjacent telescopic plates 441 (the gap between adjacent telescopic plates 441 may cause a small amount of impurities to leak out when the front spiral blade 43 transports impurities). When the telescopic plate 441 retracts into the front spiral blade 43, due to the arc-shaped surface 4472 of the baffle plate 4471, the arc-shaped surface 4472 contacts the outer side of the front spiral blade 43, causing the arc-shaped surface 4472 to be stressed. Subsequently, the baffle plate 4471 moves inward into the telescopic plate 441. When the section contracts, the clamping spring 4473 is compressed, and the sliding rod 4474 acts as a guide. At this time, the telescopic plate 441 can enter the front spiral blade 43. When the telescopic plate 441 extends out of the front spiral blade 43, the arc-shaped surface 4472 is not subjected to pressure from the outside of the front spiral blade 43. At this time, the clamping spring 4473 extends, driving the blocking plate 4471 to extend. The two adjacent blocking plates 4471 are staggered, forming a filling between the two adjacent telescopic plates 441, improving the conveying efficiency of impurities.

[0026] like Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown, the front auger propulsion unit 4 and the rear auger sludge discharge unit 5 are detachably connected by a connecting unit 6. The connecting unit 6 includes a rear connecting component 61, which includes a rear connecting column 611. The rear connecting column 611 has a hexagonal prism shape on the outside and is located at the tail end of the front auger propulsion unit 4 and the rear auger sludge discharge unit 5. A rectangular connecting seat 612 is fixedly connected inside the rear connecting column 611. A connecting cavity 614 is opened on the rectangular connecting seat 612. A through rear screw hole 613 is opened on the rear connecting column 611 and the rectangular connecting seat 612. The connecting unit 6 also includes a front connecting component 62, which includes a front connecting post 621. The front connecting post 621 has a hexagonal interior and is adapted to the rear connecting post 611. A rectangular connecting block 622 is fixedly connected inside the front connecting post 621. The rectangular connecting block 622 is adapted to the connecting cavity 614. A through front screw hole 623 is provided on the rectangular connecting block 622 and the front connecting post 621. A fracture recovery unit 7 is provided at the end of the front rotating tube 41. The fracture recovery unit 7 includes a steel disc 71, which is fixedly connected to the forward end of the front rotating tube 41. A steel wire rope 72 is fixedly connected to the steel disc 71, and the other end of the steel wire rope 72 is fixedly connected to a rectangular connecting seat 612 at the tail of the front rotating tube 41. In the rear rotating tube 51, a steel wire rope 72 is fixedly connected between a rectangular connecting block 622 and a rectangular connecting seat 612. A hydraulic winch 73 is provided at the tail of the push platform 11. By connecting the steel wire rope 72 and the hydraulic winch 73, multiple steel wire ropes 72 connected in series pull the steel disc 71 to pull the fractured component out of the pipe 100. The rotating tube 41 and multiple rear rotating tubes 51 are connected by multiple steel wire ropes 72. The connecting unit 6 connects the multiple steel wire ropes 72 in series. When the front rotating tube 41 or the rear rotating tube 51 is disconnected, it is not possible to pull out the front rotating tube 41 and the rear rotating tube 51 according to the previous method. At this time, the traction rope on the hydraulic winch 73 is connected to the rectangular connecting seat 612 at the tail of the rear rotating tube 51. Then, the hydraulic winch 73 is driven to work, so that the steel wire rope 72 pulls the steel disc 71 to move. At this time, the steel disc 71 can push the disconnected front rotating tube 41 or rear rotating tube 51 away from the pipeline 100, completing the disconnection and recovery work.

[0027] The rear end of the central shaft 125 is equipped with a lubrication and cooling unit 8, which includes a drainage channel 82. The drainage channel 82 is located inside the central shaft 125 and is connected to a water tank 81 through a water guide pipe. The water tank 81 supplies water to the drainage channel 82. During dredging, the water tank 81 pumps water into the drainage channel 82 through the water guide pipe. The drainage channel 82 then passes the water into the front rotating pipe 41 and the rear rotating pipe 51, and discharges it into the pipe 100 through the front threaded hole 623, the rear threaded hole 613, and the gap at the connection. The water can form a lubricating layer between the spiral blade and the inner wall of the pipe, effectively reducing the coefficient of friction and providing lubrication. At the same time, it carries away the heat generated by friction, achieving a cooling effect and preventing the risk of fire in the pipe caused by sparks generated by the friction between the triangular protruding cone 42 and the spiral blade and the inner wall of the oil pipe. In this embodiment, after the front-end auger propulsion unit 4 enters the pipe 100, due to the long length of the pipe 100, multiple rear-end auger sludge removal units 5 need to be connected subsequently. During connection, the drive motor 13 is first controlled to operate, causing the connector and the tail of the front-end rotating pipe 41 to separate. Then, the tail of the rear-end rotating pipe 51 is connected to the connector 16 (the tail of the rear-end rotating pipe 51 is the rear connecting post 611, which is compatible with the connector 16). Then, the drive motor 13 is controlled to move the connector 16 and the rear-end rotating pipe 51 closer to the front-end auger 41. The end rotating tube 41 is rotated so that the front connecting post 621 of the rear rotating tube 51 is inserted into the rear connecting post 611 of the front rotating tube 41. At this time, the rectangular connecting block 622 in the front connecting post 621 is inserted into the connecting cavity 614 in the rear connecting post 611. At the same time, the front screw hole 623 and the rear screw hole 613 are connected. The user then uses bolts to connect the front rotating tube 41 and the rear rotating tube 51. Then, the drive rotating unit 12 and the drive motor 13 drive the front rotating tube 41 and the rear rotating tube 51 to rotate and enter the pipe 100 for sludge removal.

[0028] It is important to understand that the first section uses the front-end auger propulsion unit 4 because its front end has a triangular protruding cone 42, and the front spiral blade 43 of the front-end rotating tube 41 within it is equipped with a compensation structure 44 for cleaning the corroded areas of the pipeline 100. Subsequently, due to the length of the pipeline 100, the subsequent units connected in series are all rear-end auger sludge removal units 5, whose main function is to transport impurities.

[0029] The workflow is as follows: First, the pipe 100 to be cleaned is placed on the bracket. Then, the robotic arm is operated to grab the front auger propulsion unit 4. The front auger propulsion unit 4 is the first structure to enter the pipe 100. The tail of the front rotating tube 41 in the front auger propulsion unit 4 is connected to the connector 16. Then, the rotating unit 12 is operated to drive the front rotating tube 41 to rotate. At the same time, the drive motor 13 is used to drive the front rotating tube 41 to approach the pipe 100. First, the triangular protruding cone 42 enters the interior of the pipe 100. The rotating triangular protruding cone 42 can break up larger deposits inside the pipe 100. At the same time, the front spiral blade 43 on the front rotating tube 41 rotates along with it. The rotating front spiral blade 43 adheres to the inner wall of the pipe 100, further breaking up the deposits on the inner wall of the pipe 100. At the same time, the rotating front spiral blade 43 and the inner wall of the pipe 100 cooperate to allow the broken deposits to be conveyed out of the pipe 100 by the front spiral blade 43, completing the internal cleaning of the pipe 100. During the above process, corrosion occurs in some areas inside the pipe 100, resulting in an irregular circular cross-section. This prevents the front rotating pipe 41 from cleaning the irregular areas when it drives the front spiral blade 43 to rotate. Therefore, in this application, the front spiral blade 43 is equipped with multiple telescopic plates 441. When the front rotating pipe 41 is inside the pipe 100, the telescopic plates 441 are always in contact with the inner wall of the pipe 100 under the elastic action of the elastic sheet 443. When the inner wall of the pipe 100 is concave, the telescopic plates 441 slide outward under the elastic action of the elastic sheet 443, allowing the end of the telescopic plates 441 to extend into the bottom of the concave area to clean the deposits attached to the bottom of the concave surface. When the inner wall of the pipe 100 is convex, the telescopic plates 441 slide inward into the front spiral blade 43 under the elastic action of the elastic sheet 443, and the elastic sheet 443 is squeezed, allowing the front spiral blade 43 to pass through the convex part inside the pipe 100. It can also take into account the corroded areas inside pipe 100, because the inner wall of the pipe in the corroded area is not smooth, which makes it easier for impurities to accumulate. Therefore, it needs to be given special attention to improve the dredging effect of pipe 100.After the front-end auger propulsion unit 4 enters the pipe 100, due to the length of the pipe 100, multiple rear-end auger sludge removal units 5 need to be connected. During connection, the drive motor 13 is first controlled to work, causing the connector and the tail of the front-end rotating tube 41 to separate. Then, the tail of the rear-end rotating tube 51 is connected to the connector 16. Subsequently, the drive motor 13 is controlled to drive the connector 16 and the rear-end rotating tube 51 closer to the front-end rotating tube 41, so that the front connecting post 621 of the rear-end rotating tube 51 is inserted into the rear connecting post 611 of the front-end rotating tube 41. At this time, the rectangular connecting block 622 in the front connecting post 621 is inserted into the connecting cavity 614 in the rear connecting post 611. At the same time, the front screw hole 623 and the rear screw hole 613 are connected. At this time, the user uses bolts to connect the front-end rotating tube 41 and the rear-end rotating tube 51. Then, the drive rotation unit 12 and the drive motor 13 drive the front-end rotating tube 41 and the rear-end rotating tube 51 to rotate and enter the pipe 100 for sludge removal. The first section uses a front-end auger propulsion unit 4. This unit has a triangular protruding cone 42 at its front end, and a compensation structure 44 on the front spiral blade 43 of the front rotating tube 41, used to clean corroded areas of the pipeline 100. Subsequently, due to the length of the pipeline 100, subsequent units connected in series are rear-end auger sludge removal units 5, primarily used for transporting impurities.
