Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, specifically, it relates to a pipeline inner wall cleaning device. 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. Typically, fluids are pressurized by blowers, compressors, pumps, boilers, etc., and then flow from the high-pressure area to the low-pressure area in the pipeline. They can also be transported using the fluid's own pressure or gravity. Pipelines have a wide range of applications, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations. The process of ensuring that the inner surface of the pipeline is restored to its original surface material is also important.

[0003] Chinese patent application number CN202220287265.4 discloses a pipe inner wall cleaning device, belonging to the field of pipe technology. Its key technical features include a sleeve, with a transmission rod movably connected to the inner wall of the sleeve. A connecting rod is movably connected to the left side of the transmission rod, and a brush roller is fixedly connected to the surface of the connecting rod. Knobs are threaded to both the front and rear sides of the sleeve, and a transmission mechanism is fixedly connected to the rear side of the sleeve. The transmission mechanism includes a housing, a first bevel gear, a fixed column, and a motor. This invention solves the problem that in existing pipe cleaning methods, users need to manually clean the inner wall of the pipe, which is very cumbersome. Users fix a cleaning cloth to a rod, insert the rod and cleaning cloth into the inner wall of the pipe, and pull back and forth to clean the inner wall. This process is time-consuming, laborious, and the cleaning effect is unsatisfactory, negatively impacting the user's ability to clean the inner wall of the pipe.

[0004] However, the aforementioned device has significant limitations in pipe cleaning. Its reliance on high-speed rotating brushes makes it difficult to effectively remove stubborn deposits adhering to the inner walls of pipes, resulting in poor cleaning efficiency and quality. Furthermore, the device cannot be adapted to pipes of different lengths and sizes, and its operation is cumbersome and complex when faced with diverse pipe cleaning needs, making it difficult to meet the requirements of efficient and comprehensive cleaning in practical applications.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pipe inner wall cleaning device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A pipe inner wall cleaning device includes a base, a plurality of pipe placement racks are provided on the base, a support plate is provided on the base, a telescopic mechanism is provided on one side of the support plate, a rotating disk is provided at one end of the telescopic mechanism, and a cleaning mechanism is provided around the rotating disk.

[0009] The cleaning mechanism includes a cavity set inside a rotating disk, a toothed ring rotatably fitted inside the cavity, and multiple arc-shaped movable plates rotatably fitted on the toothed ring. A limit groove is provided on one side of the inner wall of the cavity. One end of the arc-shaped movable plate is movably connected to a sliding plate that is slidably fitted in the limit groove.

[0010] Optionally, the control component includes a gear that is rotatably fitted in the cavity and meshes with the gear ring, a knob that is rotatably fitted on one side of the rotating disk, and a limiting telescopic component connected to the gear at one end of the knob, wherein a handle is provided at one end of the knob; the limiting telescopic component includes a rectangular telescopic frame provided on one side of the gear, and a rectangular telescopic plate that is slidably fitted in the rectangular telescopic frame at one end of the knob.

[0011] Optionally, the sliding support mechanism includes an elastic element disposed on the upper side of the sliding plate, with a rolling support wheel at one end of the elastic element; the elastic element includes a fixed cylinder disposed at one end of the sliding plate, with a sliding column elastically fitted inside the fixed cylinder and connected to the rolling support wheel, wherein a spring connected to the sliding column is disposed at the bottom of the inner wall of the fixed cylinder.

[0012] Optionally, one end of the connecting plate is provided with a threaded cylinder, and one end of the cleaning roller is provided with a threaded connecting rod that engages with the threaded cylinder.

[0013] Optionally, the pipe placement rack is semi-circular in shape, and a cylinder is provided on the upper side of the base.

[0014] Optionally, the telescopic mechanism includes an electric telescopic rod disposed on one side of the support plate, one end of which is equipped with a drive motor, the output end of which is connected to the rotating disk.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] The control components allow the gear ring to rotate, which, constrained by the limiting slide groove, moves the arc-shaped movable plate within the groove. This movable plate, in turn, moves the cleaning roller and scraper on the sliding plate synchronously, allowing users to flexibly adjust the movement distance of the cleaning roller and scraper. This enables easy cleaning of both large and small diameter pipes, greatly improving the device's versatility and practicality. The scraper effectively removes stubborn deposits that the cleaning roller cannot reach, significantly improving the cleaning effect and efficiency. Simultaneously, the pipe support frame stably holds the pipe to be cleaned, preventing swaying during cleaning and ensuring smooth operation. The telescopic mechanism drives the cleaning roller and scraper on the rotating disc to reciprocate within the pipe, achieving comprehensive cleaning of both short and long pipes. Furthermore, the sliding support mechanism provides stable support to the rotating disc, making the cleaning roller and scraper more stable and reliable during operation, ensuring the entire pipe cleaning process is efficient and stable.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-6 As shown, this embodiment provides a pipe inner wall cleaning device, including a base 1, a plurality of pipe placement racks 2 are provided on the base 1, a support plate 3 is provided on the base 1, a telescopic mechanism is provided on one side of the support plate 3, a rotating disk 4 is provided at one end of the telescopic mechanism, and a cleaning mechanism is provided around the rotating disk 4.

[0030] The cleaning mechanism includes a cavity set inside the rotating disk 4, a toothed ring 5 rotatably fitted inside the cavity, and multiple arc-shaped movable plates 6 rotatably fitted on the toothed ring 5. Multiple limiting grooves are provided on one side of the inner wall of the cavity. One end of the arc-shaped movable plate 6 is movably connected to a sliding plate 7 that is slidably fitted in the limiting groove. A connecting plate 8 is provided on one side of the sliding plate 7. A scraper 9 and a cleaning roller brush 10 are provided on the connecting plate 8. A sliding support mechanism is provided on the upper side of the sliding plate 7. A control component that cooperates with the toothed ring 5 is provided on one side of the rotating disk 4.

[0031] One application of this embodiment is that the operation steps are clear and convenient when using this device to clean pipes. First, the parameters need to be adjusted according to the size and specifications of the pipe to be cleaned: start the control unit to drive the toothed ring 5 to start rotating. During the rotation of the toothed ring 5, the arc-shaped movable plate 6 moves precisely along the limiting slide groove. This movement is driven by mechanical transmission, which simultaneously drives the sliding plate 7 and the connecting plate 8 to move, thereby realizing the position adjustment of the scraper 9 and the cleaning roller brush 10 on the connecting plate 8 to fit the inner diameter of the pipe. After the position adjustment is completed, start the telescopic mechanism. The cleaning roller brush 10 and the scraper 9 will advance at a constant speed along the axial direction of the pipe while rotating. With their continuous rotation and forward movement, the dirt and impurities on the inner wall of the pipe will be thoroughly removed, and the cleaning operation will be completed efficiently.

[0032] The control components allow the toothed ring 5 to rotate, which, constrained by the limiting slide groove, moves the arc-shaped movable plate 6 within the groove. The arc-shaped movable plate 6 then moves the cleaning roller brush 10 and scraper 9 on the sliding plate 7 synchronously, allowing the user to flexibly adjust the movement distance of the cleaning roller brush 10 and scraper 9. This enables easy cleaning of both large and small diameter pipes, greatly improving the device's versatility and practicality. Furthermore, the scraper 9 effectively removes stubborn deposits that are difficult for the cleaning roller brush 10 to reach. This significantly improves the effectiveness and efficiency of pipe cleaning. At the same time, the pipe placement rack 2 can stably support the pipe to be cleaned, preventing it from shaking during the cleaning process and ensuring that the cleaning work is carried out smoothly. With the telescopic mechanism, it can drive the cleaning roller brush 10 and scraper 9 on the rotating disk 4 to reciprocate inside the pipe, achieving comprehensive cleaning for both short and long pipes. In addition, the sliding support mechanism provides stable support for the rotating disk 4, making the cleaning roller brush 10 and scraper 9 more stable and reliable during operation, ensuring that the entire pipe cleaning process is efficient and stable.

[0033] like Figure 1-4 As shown, the control component in this embodiment includes a gear 11 that is rotatably fitted in the cavity and meshes with the gear ring 5. A knob 12 is rotatably fitted on one side of the rotating disk 4. One end of the knob 12 is provided with a limiting telescopic component connected to the gear 11. A handle is provided on one end of the knob 12. The limiting telescopic component includes a rectangular telescopic frame 27 provided on one side of the gear 11. A rectangular telescopic plate 13 that is slidably fitted in the rectangular telescopic frame 27 is provided on one end of the knob 12. The handle design facilitates operation by allowing staff to easily rotate the knob 12 by gripping it. As the knob 12 rotates, the rectangular telescopic plate 13 and the rectangular telescopic frame 27 also rotate. The rotation of the rectangular telescopic frame 27, in turn, drives the gear 11 to rotate. One end of the knob 12 is equipped with a turntable, and one side of the turntable is equipped with a rod. Multiple slots are arranged in a circular array around the knob 12 on one side. After the gear 11 precisely drives the gear ring 5, the rod on one side of the turntable is inserted into the slot when the knob 12 is pressed to complete the fixation. This unique structural design ensures that the gear 11 rotates only around its own axis during rotation and does not produce axial displacement. Based on this, gear 11 can precisely drive the gear ring 5 to rotate, thereby flexibly adjusting the working position of the cleaning roller brush 10 and scraper 9. Whether it is a small-diameter or large-diameter pipe, the equipment can quickly adapt and achieve efficient cleaning. The whole operation process is simple and intuitive, significantly reducing the difficulty of operation for workers and improving work efficiency. In addition, the set insertion slot can be locked to prevent gear 11 from rotating back after rotation.

[0034] like Figure 2-5As shown, the sliding support mechanism of this embodiment includes an elastic element 14 disposed on the upper side of the sliding plate 7, with a rolling support wheel 15 disposed at one end of the elastic element 14; the elastic element 14 includes a fixed cylinder 28 disposed at one end of the sliding plate 7, and a sliding column 16 elastically fitted inside the fixed cylinder 28 and connected to the rolling support wheel 15, wherein a spring connected to the sliding column 16 is disposed at the bottom of the inner wall of the fixed cylinder 28. When the sliding plate 7 moves, the rolling support wheel 15 will come into close contact with the inner wall of the pipe. At the moment of contact, the compressed spring is subjected to force, pushing the sliding column 16 to slide within the fixed cylinder 28, continuously providing pressure to the rolling support wheel 15. With the help of the elastic restoring characteristics of the spring, the rolling support wheel 15 remains stable when moving inside the pipe and will not shake due to unevenness of the inner wall of the pipe. This design not only ensures the smooth operation of the rolling support wheel 15, but also provides reliable support for the cleaning roller brush 10 and scraper 9 on the rotating disk 4, allowing them to function stably during the pipe cleaning process and avoiding the impact of unstable support on the cleaning effect.

[0035] like Figure 1-4 As shown, in this embodiment, one end of the connecting plate 8 is provided with a threaded cylinder 17, and one end of the cleaning roller brush 10 is provided with a threaded connecting rod 18 that engages with the threaded cylinder 17. With the threaded connecting rod 18, the cleaning roller brush 10 can be easily disassembled from the threaded cylinder 17 using the principle of thread engagement. In actual use, the cleaning roller brush 10 may inevitably be damaged due to prolonged friction with the inner wall of the pipe. At this time, thanks to this convenient disassembly method, workers can promptly remove the damaged cleaning roller brush 10 and quickly replace it, ensuring that the equipment can continuously and efficiently complete the pipe cleaning work, effectively reducing equipment downtime caused by cleaning roller brush damage.

[0036] like Figure 1 and 6As shown, the pipe placement rack 2 in this embodiment is semi-circular in shape, and a cylinder 19 is provided on the upper side of the base 1. The output end of the cylinder 19 is provided with a cylinder rod 20 connected to the pipe placement rack 2. Mounting plates 21 are provided on opposite sides of the pipe placement rack 2. A second lead screw 22 is threaded onto the mounting plate 21. One end of the second lead screw 22 is movably connected to an arc-shaped clamping plate 23. Multiple limiting telescopic rods 24 are provided between the pipe placement rack 2 and the arc-shaped clamping plate 23. The pipe placement rack 2 adopts a semi-circular arc design, which can naturally fit the bottom of the pipe, providing a stable foundation for placing the pipe to be cleaned. The arc-shaped clamping plate 23 is a key component to ensure the stability of the pipe, which can firmly clamp the pipe on the placement rack. The operator only needs to turn the control knob at one end of the second lead screw 22. Under the guidance of the limiting telescopic rods 24, the rotational movement of the lead screw will be converted into the linear displacement of the arc-shaped clamping plate 23, thereby achieving precise clamping of the pipe. It is worth mentioning that the curved surface of the arc-shaped clamp 23 perfectly matches the outer wall of the pipe, effectively increasing the contact area. In addition, the arc-shaped anti-slip pad covering the surface further enhances friction, ensuring the pipe remains stable even when the equipment vibrates during cleaning. This dual-protection fixing method not only simplifies the operation process but also significantly improves the reliability of pipe fixing, laying a solid foundation for subsequent cleaning work. Furthermore, to ensure the arc-shaped clamp 23 stably clamps the pipe, a bearing connection is added between the second lead screw 22 and the arc-shaped clamp 23. This design effectively blocks torque transmission during lead screw rotation, preventing the arc-shaped clamp 23 from spinning freely with the lead screw. When the control knob drives the second lead screw 22 to rotate, the bearing allows the lead screw to rotate freely, while the arc-shaped clamp 23 moves smoothly in a straight line only under the guidance of the limiting telescopic rod 24. This "rotation separation" structural design significantly improves the positioning accuracy and clamping stability of the arc-shaped clamp 23, making pipe fixing more reliable and ensuring safe and efficient cleaning operations.

[0037] like Figure 1As shown, the telescopic mechanism in this embodiment includes an electric telescopic rod 25 disposed on one side of the support plate 3. A drive motor 26 is disposed at one end of the electric telescopic rod 25, and the output end of the drive motor 26 is connected to the rotating disk 4. This device achieves synchronous rotation and linear movement of the rotating disk 4 through the coordinated operation of the electric telescopic rod 25 and the drive motor 26. During this process, the cleaning roller brush 10 and scraper 9 installed on the rotating disk 4 work together to efficiently clean and scrape the inner wall of the pipe. It is worth mentioning that the scraper 9 adopts an arc-shaped design and fits the inner wall of the pipe at a horizontal angle. Multiple scrapers work together to not only fit the curved surface of the pipe tightly, but also effectively eliminate cleaning dead corners, significantly improving the efficiency of pipe cleaning. In addition, the arc-shaped movable plate 6 innovatively adopts a double movable connecting rod structure. The two connecting rods are flexibly connected through a rotating shaft. One connecting rod is movably connected to the sliding plate 7, and the other is rotated with the toothed ring 5. This ingenious design allows the sliding plate 7 to maintain a continuous and stable movement during movement, avoiding the jamming or displacement problems that may occur in traditional structures, and providing a reliable guarantee for the smooth operation of the cleaning components.

[0038] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
