Description

Technical Field

[0001] This utility model relates to the field of pulse pipeline cleaning technology, and in particular to a pipeline cleaning device based on air-water pulse technology. Background Technology

[0002] Air-water pulse pipeline cleaning technology utilizes physical principles, using vibration waves and high-speed water flow to clean stains. Unlike using chemical reagents for pipeline cleaning, physical air pressure pulse technology does not require any chemical reagents during use, so it will not cause additional damage to the pipeline, and more importantly, it will not affect the water quality in the pipeline.

[0003] In existing technologies, pipes are usually fixed by manual adjustment or simple clamping structures, which are difficult to adapt to different pipe diameters or materials. They are prone to loosening or displacement under high-pressure pulse action. This unstable fixing method will cause fluctuations in the pressure and flow of the pulse flow, reduce the cleaning effect, and may even affect the safety of operation due to pipe displacement. In addition, manual adjustment of the fixing structure is not only inefficient, but also increases labor intensity, making it difficult to meet the needs of efficient and automated cleaning. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline cleaning device based on air-water pulse technology, comprising a support frame and a snap-fit ​​sleeve. Positioning frames are fixedly connected to the outer perimeter of the snap-fit ​​sleeve. Electric push rods are fixedly connected to the opposite sides of the positioning frames. Push plates are fixedly connected to the output ends of the electric push rods. One end of a connecting column is fixedly connected to the opposite side of the push plates.

[0006] Furthermore, a fixing plate is fixedly connected to the upper part of the support frame, a hydraulic cylinder is fixedly connected to the upper part of the fixing plate, a press is fixedly connected to the output end of the hydraulic cylinder, a docking sleeve is fixedly connected to the bottom of the press, and limit components are fixedly connected to both sides of the docking sleeve. The limit components are used to limit the docking sleeve, and the snap-fit ​​sleeve is fixedly connected to the bottom of the docking sleeve.

[0007] Furthermore, the limiting assembly includes a connecting plate, a rack plate, and gears. The two connecting plates are fixedly connected to the outer sides of the mating sleeve, the two rack plates are fixedly connected to the upper part of the two connecting plates, and the two gears are meshed on the opposite sides of the two rack plates.

[0008] Furthermore, positioning plates are fixedly connected to both sides of the inner side of the fixing plate, and the two gears are rotatably connected inside the positioning plates.

[0009] Furthermore, both rack plates are slidably connected to the inner sides of the fixed plate, and the press and the docking sleeve are slidably connected to the inside of the support frame.

[0010] Furthermore, the multiple connecting posts are slidably connected to the inside periphery of the snap-fit ​​sleeve, and the multiple connecting posts are slidably connected to the inside sides of the positioning frame.

[0011] Furthermore, all of the clamping elements are slidably connected around the inside of the snap-fit ​​sleeve.

[0012] Furthermore, one end of each of the plurality of reset springs is fixedly connected to the side of the plurality of positioning frames that are far apart, and the other end of each of the plurality of reset springs is fixedly connected to the side of the plurality of push plates that are close together.

[0015] 2.

[0022] 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.

[0023] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a pipeline cleaning device based on air-water pulse technology, comprising a support frame 1 and a snap-fit ​​sleeve 6. Positioning frames 11 are fixedly connected to the outer periphery of the snap-fit ​​sleeve 6. Electric push rods 12 are fixedly connected to the opposite sides of the positioning frames 11. Push plates 13 are fixedly connected to the output ends of the electric push rods 12. One end of a connecting post 14 is fixedly connected to the opposite side of the push plates 13. Clamping members 16 are fixedly connected to the other ends of the connecting posts 14. Return springs 15 are sleeved on the outer periphery of the connecting posts 14. The connecting posts 14 are slidably connected to the inner periphery of the snap-fit ​​sleeve 6. The connecting posts 14 are slidably connected to the inner sides of the positioning frames 11. The clamping members 16 are slidably connected to the inner periphery of the snap-fit ​​sleeve 6. One end of each return spring 15 is fixedly connected to the opposite side of the positioning frames 11, and the other end of each return spring 15 is fixedly connected to the side close to the push plates 13.

[0024] The docking sleeve 5 is connected to the pipe to ensure accurate connection between the pipe and the cleaning device. Once the pipe and the docking sleeve 5 are connected, multiple electric push rods 12 are activated. The output end of the electric push rod 12 drives the push plate 13 to move. As the push plate 13 moves, the connecting column 14 slides inside the positioning frame 11 and the snap-fit ​​sleeve 6. The positioning frame 11 provides a sliding track for the connecting column 14 to ensure accurate sliding. When the push plates 13 approach each other, they will exert a squeezing effect on the return spring 15. The return spring 15 is squeezed when the push plates 13 approach each other, accumulating energy so as to help the clamping member 16 return when needed, thereby causing the connecting column 14 to drive the clamping member 16 to come together tightly.

[0025] Reference Figure 1 and Figure 2A fixed plate 2 is fixedly connected to the upper part of the support frame 1. A hydraulic cylinder 3 is fixedly connected to the upper part of the fixed plate 2. A press 4 is fixedly connected to the output end of the hydraulic cylinder 3. A docking sleeve 5 is fixedly connected to the bottom of the press 4. Limiting components are fixedly connected to both sides of the docking sleeve 5. The limiting components are used to limit the docking sleeve 5. A snap-fit ​​sleeve 6 is fixedly connected to the bottom of the docking sleeve 5. The limiting components include a connecting plate 7, a rack plate 8, and a gear 9. The two connecting plates 7 are fixedly connected to the outer sides of the docking sleeve 5. The two rack plates 8 are fixedly connected to the upper part of the two connecting plates 7. The two gears 9 are meshed and connected to the two rack plates 8 on the opposite sides. Positioning plates 10 are fixedly connected to both sides of the inside of the fixed plate 2. The two gears 9 are rotatably connected to the inside of the positioning plates 10. The two rack plates 8 are slidably connected to both sides of the inside of the fixed plate 2. The press 4 and the docking sleeve 5 are slidably connected to the inside of the support frame 1.

[0026] The support frame 1 provides stable support for the entire device. After the support frame 1 is firmly placed, the hydraulic cylinder 3 is activated, and its output end will push the press 4 and the docking sleeve 5 to move downward smoothly. The press 4 is used to increase the pressure of the cleaning fluid and improve the cleaning efficiency. As the docking sleeve 5 moves downward, the two connecting plates 7 move accordingly, causing the rack plate 8 to slide inside the fixed plate 2. The rack plate 8 slides inside the fixed plate 2, and through the meshing of the rack and gear 9, the motion mode is changed, realizing the rotation of the gear 9. During this process, the up and down movement of the two rack plates 8 causes the two gears 9 to rotate inside the positioning plate 10. The positioning plate 10 provides a fixed motion trajectory for the gear 9 to ensure that the rotation of the gear 9 is accurate and stable. At the same time, the movement of the docking sleeve 5 also causes the bottom snap-fit ​​sleeve 6 to move accordingly.

[0027] Working principle: After the support frame 1 is placed stably, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 pushes the press 4 and the docking sleeve 5 downward. When the docking sleeve 5 moves, it drives the two connecting plates 7 to move as well. When the connecting plates 7 move, they drive the rack plate 8 to slide inside the fixed plate 2. When the two rack plates 8 move up and down, they drive the two gears 9 to rotate inside the positioning plate 10. The movement of the docking sleeve 5 drives the bottom locking sleeve 6 to move, realizing automatic adjustment of the height of the locking sleeve 6. This allows the cleaning device to adapt to pipes of different heights without manual adjustment, saving time and labor, and improving efficiency. To improve the efficiency of the cleaning operation, after the pipe and the connecting sleeve 5 are connected, multiple electric push rods 12 are activated. The output end of the electric push rod 12 drives the push plate 13 to move. When the push plate 13 moves, it drives the connecting column 14 to slide inside the positioning frame 11 and the snap-fit ​​sleeve 6. The multiple push plates 13 approach each other and squeeze the return spring 15, thereby causing the multiple connecting columns 14 to drive the multiple clamping parts 16 to approach each other until the pipe is fixed. This achieves effective clamping and fixing of the pipe, which can ensure that the pressure and flow rate of the pulse flow remain stable during the cleaning process. This is conducive to thoroughly removing dirt and deposits from the inner wall of the pipe and ensuring the cleaning quality.
