Description

Technical Field

[0001] This invention relates to the field of trenchless treatment technology for drainage pipe networks, and in particular to a waste removal device for repairing drainage pipe networks. Background Technology

[0002] In drainage pipe network maintenance and repair, silt, debris, scale, and other waste adhering to the inner wall of the pipes can severely affect the adhesion of repair materials and the quality of repairs. Therefore, pre-treatment and cleaning of the pipe interior is necessary before repairs. Existing cleaning devices mostly employ a single-stage rigid cleaning structure, using a traveling mechanism to drive the cleaning brush to rub against the pipe wall. However, the inner wall of the pipe often has uneven joints, deformations, protrusions, and hard deposits. Rigid cleaning structures cannot adaptively adjust, easily leading to problems such as jamming, excessive cleaning force damaging the pipe wall, and incomplete cleaning. This results in poor cleaning effectiveness and operational safety, failing to meet the requirements for efficient and safe cleaning before drainage pipe network repairs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a waste cleaning device for drainage pipe network repair, which solves the problems of rigid connection, inability to adaptively avoid obstacles, easy damage to pipe walls, and incomplete cleaning in existing cleaning devices.

[0004] The technical solution of this invention is as follows: A waste cleaning device for drainage pipe network repair includes a collection tank, a rubber arc-shaped sheet at the front end of the collection tank, and a frame at the upper end; a support block is fixed on the frame, a second rotating plate is rotatably mounted on the support block, a first rotating plate is movably connected to both ends of the second rotating plate, a first cleaning brush is mounted on the first rotating plate and a rotating mechanism is configured thereon; a second cleaning brush and a driving mechanism are arranged inside the collection tank; multiple auxiliary wheels are rotatably mounted at the bottom of the collection tank, and a drive wheel walking mechanism driven by a dual-head motor is arranged at the rear end.

[0005] Furthermore, the walking mechanism uses a dual-head second motor to synchronously drive two drive wheels, which are positioned behind the collection tank so as not to interfere with the front-end cleaning operation.

[0006] Furthermore, a first spring connects the first rotating plate and the second rotating plate, which can adaptively deflect when encountering obstacles and automatically reset via the first spring.

[0007] Furthermore, the rotating mechanism consists of a gear set and a second spring. The second spring provides flexible buffering to prevent the brush from rigidly damaging the tube wall.

[0008] Furthermore, the second cleaning brush at the bottom is driven to rotate by a fourth motor, a deflection shaft, a traction shaft, and a turntable, which, together with the rubber arc-shaped sheet, sweeps the waste into the collection trough.

[0009] After adopting the above technical solution, the waste cleaning device for drainage pipe network repair of the present invention has the following advantages: 1. By setting up a linkage structure of the first rotating plate, the second rotating plate and the first spring, the present invention enables the first cleaning brush to adaptively deflect the angle when it encounters obstacles on the inner wall of the pipe, effectively bypassing the obstacles and automatically resetting after passing through. This significantly improves the adaptability of the cleaning device to complex pipe environments, avoids damage to the pipe wall caused by rigid contact, and ensures the continuity and safety of the cleaning process. 2. This invention, by setting the walking mechanism behind the collection tank and adopting a support walking method combining active wheels and auxiliary wheels, ensures that the device moves stably forward in the pipeline while the front-end cleaning operation is not disturbed by the walking structure. 3. By setting up a rubber arc-shaped sheet in conjunction with a second cleaning brush, the waste at the bottom of the pipeline is effectively collected and gathered, improving the thoroughness and efficiency of waste cleaning and providing a good foundation for subsequent repair work.

[0012] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0013] Example 1 Please refer to the following: Figures 1-8 A waste cleaning device for repairing drainage pipe networks includes a collection tank 1, a rubber arc-shaped sheet 4 at the front end of the collection tank 1, a frame 8 at the upper end of the collection tank 1, a support block 5 fixedly installed on the frame 8, a second rotating plate 10 rotatably installed on the support block 5, a first rotating plate 9 movably connected to both ends of the second rotating plate 10, a first cleaning brush 6 rotatably installed on each of the two first rotating plates 9, and a rotating mechanism connected to the first cleaning brush 6 on the first rotating plate 9. The collection trough 1 is also equipped with a second cleaning brush 7. The second cleaning brush 7 is connected to the frame 8 via a connecting shaft 22. The frame 8 is equipped with a drive mechanism, which is used to drive the second cleaning brush 7 to rotate. The bottom of the collection trough 1 is rotatably connected to multiple auxiliary wheels 3. A walking mechanism is provided at the rear end of the collection trough 1. The walking mechanism includes two drive wheels 2. The frame 8 includes an inclined section and a horizontal section. The inclined section is fixedly connected to the support block 5, and the horizontal section is connected to the second cleaning brush 7. The frame 8 is a support structure for connecting the first cleaning brush 6 and the second cleaning brush 7, and is used to connect them to the collection trough 1.

[0014] Two support plates 13 are symmetrically fixedly installed at the rear end of the collection tank 1. Two drive wheels 2 are rotatably mounted on the two support plates 13 respectively. A second motor 14 is fixedly installed on the inner side of one of the support plates 13. One drive end of the second motor 14 is fixedly connected to the adjacent drive wheel 2, and the other drive end of the second motor 14 is fixedly connected to the other drive wheel 2 through a roller shaft 12. The second motor 14 is a double-headed motor. The second motor 14 drives the two drive wheels 2 to rotate. The rotation of the drive wheels 2 propels the device to move inside the pipeline. The drive wheels 2 are located behind the cleaning structure to avoid the walking mechanism from interfering with normal cleaning operations.

[0015] The bottom of the collection tank 1 has multiple grooves 11, and an auxiliary wheel 3 is rotatably installed in each groove 11. The auxiliary wheels 3 are added to the bottom of the collection tank 1 to support and assist the collection tank 1 in moving within the pipe.

[0016] The first cleaning brush 6 is mounted on the first rotating plate 9 via a rotating shaft 16. A first spring 17 connects the first rotating plate 9 and the second rotating plate 10. A first motor 15 is fixedly mounted on the support block 5. The drive end of the first motor 15 passes through the support block 5 and is fixedly connected to the middle section of the second rotating plate 10. When the inner wall of the pipe needs to be cleaned, the first motor 15 drives the second rotating plate 10 to rotate via its drive end. The second rotating plate 10 drives the first rotating plate 9, which is connected at both ends, to rotate. The first rotating plate 9 drives the first cleaning brush 6 to move, causing the first cleaning brush 6 to rub against the inner wall of the pipe, thereby cleaning the inner wall of the pipe and removing waste from the surface, thus facilitating subsequent repair work. The first rotating plate 9 and the second rotating plate 10 are rotatably connected and supported by the first spring 17. When the second rotating plate 10 encounters an obstacle during its rotation, the first rotating plate 9 can adaptively rotate relative to the second rotating plate 10 to change its angle, allowing the first cleaning brush 6 to smoothly bypass the obstacle.

[0017] The rotating mechanism includes a third gear 21, a second gear 20, and a first gear 19, all rotatably mounted on a first rotating plate 9. A third motor 27 is fixedly connected to the first rotating plate 9. The drive end of the third motor 27 is fixedly connected to the third gear 21. The third gear 21 meshes with the second gear 20, and the second gear 20 meshes with the first gear 19. The rotating shaft 16 rotates through the first rotating plate 9 and through the first gear 19. A second spring 18 is sleeved on the rotating shaft 16. The two ends of the second spring 18 are fixedly connected to the end of the rotating shaft 16 and the first gear 19, respectively. During cleaning, the third motor 27 drives the third gear 21 to rotate via the drive end. The third gear 21 drives the meshing second gear 20 to rotate, and the second gear 20 drives the meshing first gear 19 to rotate. The first gear 19 drives the rotating shaft 16 to rotate via the second spring 18, and the rotating shaft 16 drives the first cleaning brush 6 to rotate. As the first cleaning brush 6 rotates, it can continuously clean the inner wall of the pipe. During the cleaning process, the first cleaning brush 6 is not in rigid contact with the pipe wall. The first gear 19 is connected to the rotating shaft 16 via the second spring 18. The second spring 18 is elastic. When the first cleaning brush 6 encounters an obstacle, the second spring 18 can tighten or loosen accordingly to adapt to changes in the environment and avoid damage to the pipe wall caused by excessively strong cleaning. The elasticity of the second spring 18 can also maintain the basic connection function.

[0018] Two connecting shafts 22 are provided, with one end of the connecting shaft 22 rotatably connected to one end of the second cleaning brush 7, and the other end of the connecting shaft 22 fixedly connected to the frame 8. The drive mechanism is located between the frame 8 and the second cleaning brush 7, which is positioned above the rubber arc-shaped sheet 4 on the side away from the collection tank 1. When the second cleaning brush 7 rotates, it can sweep the waste at the bottom of the pipe into the collection tank 1. The drive mechanism realizes the rotation effect of the second cleaning brush 7, and as the second cleaning brush 7 rotates continuously, it collects the waste at the bottom of the pipe.

[0019] The drive mechanism includes a traction shaft 25, a fourth motor 23 fixedly mounted on the frame 8, a first deflection shaft 24 fixedly connected to the drive end of the fourth motor 23, and a turntable 26 fixedly connected to one end of the second cleaning brush 7. The two ends of the traction shaft 25 are connected to the first deflection shaft 24 and the turntable 26, respectively. The fourth motor 23 drives the first deflection shaft 24 to rotate via its drive end. The rotation of the first deflection shaft 24 pulls the traction shaft 25, which in turn causes the turntable 26 to rotate, ultimately achieving the effect of rotating the second cleaning brush 7. The second cleaning brush 7 then collects waste from the pipe.

[0020] One end of the traction shaft 25 is rotatably connected to the end of the first deflection shaft 24 away from the driving end of the fourth motor 23, and the other end of the traction shaft 25 is rotatably connected to the side of the turntable 26 off-center. The first deflection shaft 24 is rotatably connected to the driving end of the fourth motor 23, and the traction shaft 25 is connected to the off-center ends of the fourth motor 23 and the turntable 26, respectively. Thus, when the fourth motor 23 rotates, the first deflection shaft 24 deflects, which in turn drives the turntable 26 to rotate via the traction shaft 25, causing the turntable 26 to rotate and ultimately achieving the effect of rotating the second cleaning brush 7. The connecting shaft 22 is connected to the second cleaning brush 7 near the inner side, and the turntable 26 is located at the end of the second cleaning brush 7.

[0021] In use, the device is placed inside the pipe and driven forward by the walking mechanism. The second motor 14 drives two drive wheels 2 to rotate through the drive end. Multiple auxiliary wheels 3 are rotatably installed at the bottom of the collection tank 1. The auxiliary wheels 3 are symmetrically arranged on both sides and the bottom of the collection tank 1. The auxiliary wheels 3 are used to support and drive the movement of the collection tank 1. As the drive wheels 2 rotate, the device can move inside the pipe. The collection tank 1 has a semi-arc structure, which fits the internal structure of the pipe. The auxiliary wheels 3 are set on the outer edge of the collection tank 1 so that the shape of the collection tank 1 fits the inner wall of the pipe. At the same time, the auxiliary wheels 3 can also drive the device to move inside the pipe. The walking mechanism is set at the rear of the collection tank 1. The rear controls the movement of the device, and the front cleans up waste. The collection tank 1 and the auxiliary wheels 3 roll along the inner wall of the pipe. The multiple drive wheels 2 and the multiple auxiliary wheels 3 can support and drive the device to move inside the pipe.

[0022] During cleaning, the third motor 27 drives the third gear 21 to rotate via the drive end. The third gear 21 drives the meshing second gear 20 to rotate, and the second gear 20 drives the meshing first gear 19 to rotate. The first gear 19 drives the connected rotating shaft 16 to rotate via the second spring 18. The rotating shaft 16 drives the first cleaning brush 6 to rotate. The first cleaning brush 6 rubs against the inner wall of the pipe to clean it and remove the waste attached to the pipe wall. When the first cleaning brush 6 encounters resistance, such as when the inner wall of the pipe is deformed or there is strong attached waste, the second spring 18 can adapt to the resistance by changing its shape because the first gear 19 is connected to the rotating shaft 16 via the second spring 18. This prevents the first cleaning brush 6 from using too much force and damaging the pipe wall. Strongly attached materials need to be treated by the staff later.

[0023] The first motor 15 can drive the second rotating plate 10 to rotate via the drive end, changing the cleaning position of the first cleaning brush 6. The first rotating plate 9 and the second rotating plate 10 rotate relative to each other, and a first spring 17 is provided at the connection position. The first spring 17 supports the first rotating plate 9 and the second rotating plate 10 with elasticity, so that the first rotating plate 9 and the second rotating plate 10 keep in a straight line. When the first cleaning brush 6 encounters a large obstacle, the first rotating plate 9 rotates relative to the second rotating plate 10 to bypass the obstacle. At the same time, the first spring 17 can return to its original state after bypassing the obstacle.

[0024] The swept waste falls to the bottom of the pipe. The fourth motor 23 drives the first deflection shaft 24 to rotate through the drive end. The first deflection shaft 24 drives the turntable 26 to rotate through the traction shaft 25, which in turn makes the second cleaning brush 7 rotate. As the second cleaning brush 7 rotates continuously, the waste at the bottom of the pipe is swept into the collection tank 1. The second cleaning brush 7 sweeps the waste into the collection tank 1 along the rubber arc plate 4. The rubber arc plate 4 is made of rubber and can fit the inner wall of the pipe. The rubber arc plate 4 is used to connect the collection tank 1 with the inner wall of the pipe, so that the waste can be swept into the collection tank 1 along the rubber arc plate 4, and finally the waste is collected in the collection tank 1.
