A pipe cleaning device for pipe inspection

Abstract

This utility model relates to the field of pipeline cleaning technology and discloses a pipeline cleaning device for pipeline inspection. It includes two support rings, with multiple support components fixedly connected to adjacent sides of the two support rings. A cleaning ring is fixedly connected inside each support component, and a cavity is formed inside each cleaning ring. Multiple force-supplying components are fixedly connected inside each cavity, and springs are sleeved on the outside of each force-supplying component. A limiting plate is fixedly connected to the outside of the multiple force-supplying components, and multiple brushes are fixedly connected to the outside of the limiting plate. In this utility model, the brushes clean the outside of the pipeline as they move. The outside of the pipeline then presses against the brushes, causing the brushes to press against the limiting plate. Furthermore, the limiting plate, during its movement, compresses the springs and dampers. The returning force of the springs and dampers makes the brushes fit more tightly against the outside of the pipeline, resulting in a more thorough cleaning.

Description

Technical Field

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

[0002] In oil and gas pipelines, inspection devices are used to periodically check the internal condition of the pipelines, such as for corrosion, cracks, and deformation. These devices enable real-time monitoring of pipeline health, preventing accidents such as leaks or explosions. In urban water supply and sewage pipelines, inspection devices are used to assess pipeline conditions, such as detecting sediment, leaks, corrosion, or damage. This helps ensure a safe water supply and effectively treat wastewater.

[0003] However, some existing pipe cleaning devices for pipe inspection typically involve directly installing the inspection device on the outside of the pipe to inspect it. However, they do not take into account the need to clean the outside of the pipe when there is too much dust on it, in order to prevent it from affecting the inspection results.

[0004] Therefore, a pipeline cleaning device for pipeline inspection is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pipe cleaning device for pipe inspection, which aims to improve the problem that the prior art cannot clean the outside of the pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipe cleaning device for pipe inspection includes two support rings. Multiple support components for support are fixedly connected to adjacent sides of the two support rings. A cleaning ring is fixedly connected inside the support components. A cavity is opened inside the cleaning ring. Multiple force supply components for providing force are fixedly connected inside the cavity. A spring is sleeved on the outside of the force supply components. A limit plate is fixedly connected to the outside of the multiple force supply components. Multiple brushes are fixedly connected to the outside of the limit plate.

[0008] As a further description of the above technical solution:

[0009] The support assembly includes multiple fixing rods, the front and rear sides of which are fixedly connected to the adjacent sides of the two support rings. Sliding plates are slidably connected to the outside of the fixing rods, and the outside of the multiple sliding plates are fixedly connected to the outside of the cleaning ring.

[0010] As a further description of the above technical solution:

[0011] The top of each of the two support rings is rotatably connected to a guide rod, and the bottom of each of the two support rings is rotatably connected to a drive assembly for providing force. The left and right sides of the drive assembly are threadedly connected to clamping plates.

[0012] As a further description of the above technical solution:

[0013] The limiting plate is slidably connected to the outside of the cavity, and one side of the brush is slidably connected to the inside of the cavity;

[0014] As a further description of the above technical solution:

[0015] The power supply component includes multiple dampers, one end of which is fixedly connected to the inner wall of the cavity, and the other end of which is fixedly connected to the outside of the limiting plate.

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to the inner wall of the cavity, and the other end of the spring is fixedly connected to the outside of the limiting plate;

[0018] As a further description of the above technical solution:

[0019] The drive assembly includes a handle, a bidirectional threaded rod is fixedly connected to the right side of the handle, the outside of the bidirectional threaded rod is rotatably connected to the bottom of the support ring, and the bottoms of the two clamping plates are respectively threaded to the left and right sides of the outside of the bidirectional threaded rod.

[0020] As a further description of the above technical solution:

[0021] The tops of the two clamping plates are slidably connected to the left and right sides of the outside of the guide rod, respectively, and the outside of the clamping plates is in contact with the inside of the support ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the cleaning ring, the cleaning ring can slide outside the fixed rod via the sliding plate. As the cleaning ring moves, it drives the brush to move, and the brush cleans the outside of the pipe. The outside of the pipe then presses against the brush, which in turn presses against the limiting plate. As the limiting plate moves, it compresses the spring and damper. Under the force of the spring and damper returning to their original positions, the brush fits more tightly against the outside of the pipe, resulting in a more thorough cleaning.

[0024] 2. In this utility model, by rotating the handle, the handle can drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it will drive the two clamping plates to move closer to each other. The guide rod can make the movement of the clamping plates more stable. Then, when the two clamping plates move closer to each other, they can clamp and fix the pipe, preventing the pipe from shaking in the emergency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a pipe cleaning device for pipe inspection, comprising two support rings 1. Multiple support components are fixedly connected to adjacent sides of the two support rings 1, thus providing support to the support components. A cleaning ring 4 is fixedly connected inside each support component, providing support to the cleaning ring 4. Each support component includes multiple fixing rods 2, with their front and rear sides fixedly connected to adjacent sides of the two support rings 1, allowing the support rings 1 to support the fixing rods 2. Sliding plates 3 are slidably connected to the outside of each fixing rod 2, providing support to the sliding plates 3. The outside of the multiple sliding plates 3 is fixedly connected to the cleaning ring 4. The external sliding plate 3 can provide support for the cleaning ring 4. The cleaning ring 4 has a cavity 5 inside. Multiple force-providing components are fixedly connected inside the cavity 5. Springs 7 are sleeved on the outside of the force-providing components. Limiting plates 8 are fixedly connected to the outside of the multiple force-providing components, so that the force-providing components can provide support for the limiting plates 8. One end of the spring 7 is fixedly connected to the inner wall of the cavity 5, and the other end of the spring 7 is fixedly connected to the outside of the limiting plate 8. So when the limiting plate 8 moves, it will compress the spring 7. The outside of the limiting plate 8 is slidably connected to the inside of the cavity 5. Multiple brushes 9 are fixedly connected to the outside of the limiting plate 8. One side of the brushes 9 is slidably connected to the inside of the cavity 5, so when the brushes 9 move, they will press the limiting plate 8.

[0032] Reference Figure 1 and Figure 3 The tops of both support rings 1 are rotatably connected to guide rods 10, thus providing support for the guide rods 10. The bottoms of both support rings 1 are rotatably connected to drive components for providing force, thus providing support for the drive components. Clamping plates 11 are threadedly connected to the left and right sides of the drive components, enabling the drive components to move the two clamping plates 11. The drive components include a handle 13, with a bidirectional threaded rod 12 fixedly connected to the right side of the handle 13. Rotating the handle 13 causes the handle 13 to drive the bidirectional threaded rod 12 to rotate. The bottom of the support ring 1 is rotatably connected to the bottom of the support ring 1. The bottom of the two clamping plates 11 is threaded to the left and right sides of the outside of the bidirectional threaded rod 12, respectively. When the bidirectional threaded rod 12 rotates, it will drive the two clamping plates 11 to move closer to each other. The force supply component includes multiple dampers 6. One end of the multiple dampers 6 is fixedly connected to the inner wall of the cavity 5, and the other end of the multiple dampers 6 is fixedly connected to the outside of the limiting plate 8. Then, when the limiting plate 8 moves, it will press the dampers 6. The top of the two clamping plates 11 is slidably connected to the left and right sides of the outside of the guide rod 10, respectively. The outside of the clamping plates 11 is in contact with the inside of the support ring 1.

[0033] Working principle: First, position the pipe between the two support rings 1. Rotate the handle 13 in the drive assembly, which drives the bidirectional threaded rod 12 to rotate. Since the two clamping plates 11 are threadedly connected to the left and right sides of the bidirectional threaded rod 12 respectively, when the bidirectional threaded rod 12 rotates, the two clamping plates 11 will move closer to each other under the guidance of the guide rod 10. As the clamping plates 11 move, they gradually clamp and fix the pipe, preventing the pipe from shaking during subsequent cleaning and ensuring the stability of the cleaning work.

[0034] After the pipe is clamped and secured, cleaning begins. The cleaning ring 4 is pulled, sliding outside the fixed rod 2 via the connected sliding plate 3. As the cleaning ring 4 moves, it causes the limiting plate 8 and brush 9 within its internal cavity 5 to move together. When the brush 9 contacts the outside of the pipe, the pipe surface exerts pressure on the brush 9, causing it to press against the limiting plate 8. The limiting plate 8, during its movement, compresses the spring 7 and damper 6, which are sleeved outside the power supply assembly. The restoring force generated by the compressed spring 7 and damper 6 ensures a tighter fit between the brush 9 and the outside of the pipe, allowing the brush 9 to more effectively clean the outside of the pipe during the movement of the cleaning ring 4.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
