Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a pipeline cleaning device for trenchless pipeline repair. Background Technology

[0002] When using inner sleeves for trenchless pipeline repair, it is necessary to clean the inner wall of the pipeline in advance using a traction robot to prevent impurities on the inner wall from squeezing and puncturing the inner sleeve, thus preventing leakage and ensuring the quality of pipeline repair. Existing cleaning methods generally use cleaning brushes and cleaning plates together. However, the size of existing cleaning brushes and cleaning plates is generally fixed, while the size of the pipelines to be repaired varies. Therefore, it is often necessary to customize many different sizes of cleaning devices for cleaning. This results in a large number of cleaning devices to be carried during construction, a large footprint, and great inconvenience in cleaning various pipelines of different sizes.

[0003] Chinese utility model patent CN220479635U discloses a trenchless pipe repair device for cleaning the inner wall of pipes, mainly relating to the field of pipe repair. It includes a cleaning brush and a cleaning plate, with a connecting rope between them. The cleaning brush includes a fixed plate, and multiple support rods are arrayed on the side of the fixed plate. Sleeves are slidably connected to the support rods. An adjusting rod for driving the sleeves to slide is provided on the fixed plate. A brush seat is provided at the end of the sleeve, and a cleaning head with bristles is provided on the brush seat. The cleaning plate includes a base plate, with extension plates symmetrically fitted on the base plate. A fixing rod for fixing the extension plates is provided on the base plate. The advantages of this utility model are: it solves the technical problem that existing cleaning devices are inconvenient for cleaning pipes of different sizes, can conform to the inner walls of pipes of different sizes, improves the efficiency of cleaning the inner walls of different pipes, reduces the number of devices required and the floor space occupied, and enhances the cleaning effect in actual use.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device adjusts the position of the sleeve via an adjusting rod threadedly connected to the fixed plate, thereby adjusting the position of the bristles to adapt them to pipes of different sizes. In actual use, because multiple independent bristles are connected to the fixed plate, operators must adjust the positions of multiple adjusting rods sequentially, resulting in complex operation and a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a trenchless pipeline repair and cleaning device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe cleaning device for trenchless pipe repair, comprising a fixed plate, a connecting rope connected to the fixed plate, a base plate connected to the connecting rope, and an extension plate sleeved on the base plate. Multiple support rods are fixed on the side wall of the fixed plate, and sleeves are slidably connected to the multiple support rods. Cleaning brushes are connected to the ends of the multiple sleeves. A rotating groove is opened through the side wall of the fixed plate, and a driving component for simultaneously driving multiple sleeves is provided on the sleeves.

[0007] By adopting the above technical solution, when workers need to clean the inner walls of pipes of different sizes, they need to adjust the position of the cleaning brushes. At this time, the workers need to close the limiting device and activate the drive assembly, which allows multiple sleeves to move simultaneously away from or towards the axis of the fixed plate under the action of the drive assembly. This allows for simultaneous adjustment of the positions of multiple cleaning brushes, ensuring that the positions of the cleaning brushes match the inner walls of the pipes. Furthermore, the workers need to connect the fixed plate to the traction robot via ropes and activate the traction robot, allowing the fixed plate to move along the pipe under the action of the traction robot, thus enabling the cleaning brushes to clean the inner walls of the pipes.

[0008] Furthermore, the drive assembly includes a rotating rod rotatably disposed in a rotating groove, a plurality of compression springs with one end sequentially fixed to the inner walls of a plurality of sleeves, a plurality of movable ropes with one end sequentially fixed to the inner walls of a plurality of sleeves, and a limiting device disposed on the rotating rod for limiting the rotation rod. The other ends of the plurality of compression springs are sequentially fixed to the side walls of adjacent support rods, and the other ends of the plurality of movable ropes extend into the rotating groove and are wound around the rotating rod.

[0009] Furthermore, a stabilizing groove is provided on the inner wall of the rotating groove, and a stabilizing plate is rotatably disposed in the stabilizing groove, the stabilizing plate being fixed to the rotating rod.

[0010] By adopting the above technical solution, when the operator needs to adjust the position of the cleaning brush, they need to close the limiting device, which allows multiple sleeves to move sequentially to their furthest ends under the action of multiple compression springs. Then, the operator needs to rotate the rotating rod, causing multiple moving ropes to gradually wind around the rotating rod, thereby moving multiple sleeves simultaneously towards the axis of the rotating rod, thus adjusting the position of multiple sleeves at the same time, reducing the difficulty for the operator in adjusting the position of multiple cleaning brushes. Afterwards, once the cleaning brush has moved to the appropriate position, the operator only needs to reopen the limiting device to stabilize the rotating rod, thereby stabilizing the cleaning brush.

[0011] Furthermore, the rotating rod has a threaded groove on its side wall, and a plurality of connecting grooves are formed through the inner wall of the threaded groove. The limiting device includes a plurality of connecting blocks that are slidably arranged in the plurality of connecting grooves and a threaded rod that is threadedly connected in the threaded groove. An inclined surface is formed on the side wall of the plurality of connecting blocks near the axis of the rotating rod.

[0012] By adopting the above technical solution, when the operator needs to keep the rotating rod stable, the operator needs to rotate the threaded rod, which will move the threaded rod closer to the connecting block, thereby causing the threaded rod to simultaneously press against multiple inclined surfaces. This will cause multiple connecting blocks to move away from the axis of the rotating rod under the action of the threaded rod, thereby causing multiple connecting blocks to simultaneously press against the inner wall of the rotating groove, thus keeping the rotating rod stable.

[0013] Furthermore, the end of the threaded rod is equipped with a first grip to reduce the difficulty for workers to turn the threaded rod.

[0014] Furthermore, a second grip is installed on the side wall of the rotating rod away from the threaded rod to reduce the difficulty for the operator to rotate the rotating rod.

[0015] By adopting the above technical solutions, the first grip reduces the difficulty for the operator to rotate the threaded rod, and the second grip reduces the difficulty for the operator to rotate the rotating rod, thereby effectively improving the efficiency of the operator in adjusting the position of the cleaning brush and thus improving the operator's user experience.

[0016] Furthermore, rubber sheets are installed on the sidewalls of the multiple connecting blocks away from the axis of the rotating rod.

[0017] Furthermore, the connecting rope is a connecting rope made of stainless steel wire rope.

[0018] By adopting the above technical solutions, stainless steel wire ropes utilize highly corrosion-resistant alloy materials containing elements such as chromium and nickel (e.g., 316 and 304 stainless steel). The passivation film formed on the surface effectively isolates corrosive media, making it suitable for highly corrosive environments such as acids, alkalis, and salts. Connecting ropes made of stainless steel wire ropes possess excellent corrosion resistance and structural strength, thereby effectively extending the service life of the connecting ropes and reducing the probability of breakage.

[0019] In summary, this utility model has the following beneficial effects: 1. In this application, when workers need to clean the inner walls of pipes of different sizes, they need to adjust the position of the cleaning brushes. At this time, the workers need to close the limiting device and activate the drive assembly, which allows multiple sleeves to move simultaneously away from or towards the axis of the fixed plate under the action of the drive assembly, thereby simultaneously adjusting the position of multiple cleaning brushes to match the position of the cleaning brushes with the inner wall of the pipe. Furthermore, the workers need to connect the fixed plate to the traction robot via ropes and activate the traction robot, which allows the fixed plate to move along the pipe under the action of the traction robot, thereby enabling the cleaning brushes to clean the inner wall of the pipe. 2. In this application, when the worker needs to adjust the position of the cleaning brush, the worker needs to close the limiting device, which allows multiple sleeves to move sequentially to their furthest ends under the action of multiple compression springs. Then, the worker needs to rotate the rotating rod, which allows multiple moving ropes to gradually wind around the rotating rod, causing multiple sleeves to move simultaneously towards the axis of the rotating rod, thereby simultaneously adjusting the positions of multiple sleeves and reducing the difficulty for the worker to adjust the positions of multiple cleaning brushes. After the cleaning brush has moved to the appropriate position, the worker only needs to reopen the limiting device to stabilize the rotating rod, thus stabilizing the cleaning brush. 3. In this application, when the operator needs to keep the rotating rod stable, the operator needs to rotate the threaded rod, which will move the threaded rod closer to the connecting block, thereby causing the threaded rod to simultaneously press against multiple inclined surfaces. This will cause multiple connecting blocks to move away from the axis of the rotating rod under the action of the threaded rod, thereby causing multiple connecting blocks to simultaneously press against the inner wall of the rotating groove, thus keeping the rotating rod stable.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] like Figure 1-8 As shown in the illustration, this application discloses a trenchless pipeline repair and cleaning device, comprising a fixed plate 1, a connecting rope 11, a base plate 2, an extension plate 21, support rods 3, sleeves 31, cleaning brushes 4, a drive assembly 5, a stabilizing plate 7, a first handle 8, a second handle 81, and a rubber sheet 9. One end of the connecting rope 11 is connected to the fixed plate 1. The base plate 2 is a plate-shaped structure, and the other end of the base plate 2 is connected to the connecting rope 11. The extension plate 21 is a plate-shaped structure, fitted onto the base plate 2, and used to clean stubborn impurities on the inner wall of the pipeline. The support rods 3 are round rod-shaped structures, and multiple support rods 3 are provided and sequentially fixed to the side wall of the fixed plate 1. The sleeves 31 are round rod-shaped structures with one open side, and multiple sleeves 31 are provided, each corresponding to a support rod 3, and the sleeves 31 are slidably connected to the corresponding support rods 3. Multiple cleaning brushes 4 are provided, each corresponding to a sleeve 31, and the cleaning brushes 4 are connected to the ends of the corresponding sleeves 31.

[0024] A rotating groove 41 is formed through the side wall of the fixed plate 1. A drive assembly 5 is mounted on the sleeve 31 and is used to drive multiple sleeves 31 simultaneously. The drive assembly 5 includes a rotating rod 51, compression springs 52, moving ropes 53, and a limiting device 6. The rotating rod 51 is a round rod structure and is rotatably mounted in the rotating groove 41. Multiple compression springs 52 are provided, and one end of each compression spring 52 is sequentially fixed to the inner wall of the multiple sleeves 31, while the other end is sequentially fixed to the side wall of an adjacent support rod 3. Multiple moving ropes 53 are provided, and one end of each moving rope is sequentially fixed to the inner wall of the multiple sleeves 31, while the other end of each moving rope extends into the rotating groove 41 and is wound around the rotating rod 51. A stabilizing groove 63 is formed on the inner wall of the rotating groove 41. A stabilizing plate 7 is a round plate structure and is rotatably mounted in the stabilizing groove 63, and the stabilizing plate 7 is fixed to the rotating rod 51.

[0025] When the operator needs to adjust the position of the cleaning brush 4, they must close the limiting device 6, allowing multiple sleeves 31 to move sequentially to their furthest ends under the action of multiple compression springs 52. Then, the operator rotates the rotating rod 51, causing multiple moving ropes 53 to gradually wind around it, thus moving multiple sleeves 31 simultaneously towards the axis of the rotating rod 51. This allows for simultaneous adjustment of the positions of multiple sleeves 31, reducing the difficulty of adjusting the positions of multiple cleaning brushes 4. After the cleaning brush 4 has moved to the appropriate position, the operator simply needs to reopen the limiting device 6 to stabilize the rotating rod 51, thereby stabilizing the cleaning brush 4.

[0026] A threaded groove 54 is formed on the side wall of the rotating rod 51, and multiple connecting grooves 55 are formed through the inner wall of the threaded groove 54. A limiting device 6 is provided on the rotating rod 51 to limit the rotation of the rotating rod 51. The limiting device 6 includes a connecting block 61 and a threaded rod 62. The connecting block 61 is a rectangular block structure, and multiple connecting blocks 61 are provided and slidably arranged in multiple connecting grooves 55. An inclined surface is formed on the side wall of the multiple connecting blocks 61 near the axis of the rotating rod 51. The threaded rod 62 is threadedly connected in the threaded groove 54 and is used to drive the connecting block 61.

[0027] When the operator needs to keep the rotating rod 51 stable, the operator needs to rotate the threaded rod 62, which will move the threaded rod 62 towards the connecting block 61, thereby causing the threaded rod 62 to simultaneously press against multiple inclined surfaces. This will cause multiple connecting blocks 61 to move away from the axis of the rotating rod 51 under the action of the threaded rod 62, thereby causing multiple connecting blocks 61 to simultaneously press against the inner wall of the rotating groove 41, thus keeping the rotating rod 51 stable.

[0028] The first grip 8 is installed at the end of the threaded rod 62 to reduce the difficulty for the operator to rotate the threaded rod 62. The second grip 81 is installed on the side wall of the rotating rod 51 away from the threaded rod 62 to reduce the difficulty for the operator to rotate the rotating rod 51.

[0029] The first grip 8 reduces the difficulty for the operator to rotate the threaded rod 62, and the second grip 81 reduces the difficulty for the operator to rotate the rotating rod 51, thereby effectively improving the efficiency of the operator in adjusting the position of the cleaning brush 4 and thus improving the operator's user experience.

[0030] The rubber sheet 9 has a sheet-like structure. Multiple rubber sheets 9 are provided and correspond one-to-one with the connecting block 61. Multiple rubber sheets 9 are sequentially installed on the side wall of multiple connecting blocks 61 away from the axis of the rotating rod 51.

[0031] To reduce the probability of breakage of the connecting rope 11, it is made of stainless steel wire rope. Stainless steel wire rope uses highly corrosion-resistant alloy materials containing elements such as chromium and nickel (e.g., 316 or 304 stainless steel). The passivation film formed on its surface effectively isolates corrosive media, making it suitable for highly corrosive environments such as acids, alkalis, and salts. The connecting rope 11 made of stainless steel wire rope has excellent corrosion resistance and structural strength, thus effectively extending its service life and reducing the probability of breakage.

[0032] The operating principle of the trenchless pipe repair and cleaning device in this embodiment is as follows: When workers need to clean the inner walls of pipes of different sizes, they need to adjust the position of the cleaning brushes 4. At this time, the workers need to close the limiting device 6 and turn on the drive assembly 5, so that multiple sleeves 31 can move simultaneously away from or towards the axis of the fixed plate 1 under the action of the drive assembly 5, thereby simultaneously adjusting the position of multiple cleaning brushes 4, so that the position of the cleaning brushes 4 matches the inner wall of the pipe. Furthermore, the workers need to connect the fixed plate 1 to the traction robot through a rope and turn on the traction robot, so that the fixed plate 1 can move along the pipe under the action of the traction robot, thereby allowing the cleaning brushes 4 to clean the inner wall of the pipe.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
