Description

Technical Field

[0001] This invention belongs to the field of drainage pipe dredging technology, and particularly relates to a drainage pipe dredging device. Background Technology

[0002] Drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or elsewhere, any pipe that serves a drainage function should be counted as a drainage pipeline. The length of a drainage pipeline refers to the sum of the lengths of all main drainage pipes, branch pipes, inspection wells, and connecting well inlets and outlets. Calculations should be based on a single pipe; that is, if there are two or more drainage pipelines running parallel on the same street, the lengths of each pipeline should be added together. Furthermore, dredging operations inside drainage pipelines generally require manual entry into the wells to remove impurities and silt, which is physically demanding and dangerous. Currently, dredging equipment is used for cleaning, allowing for manual removal with the aid of external machinery. However, some areas still cannot be manually cleaned.

[0003] Furthermore, currently available drainage pipe dredging devices are large, making them difficult to operate in manholes, and they also require placement on large trailers for on-site operation. The existing Chinese patent (CN213926672U) describes a drainage pipe dredging device that is also large and can only be placed at one end of the pipe, making it difficult to flush the entire pipe and adjust it according to the pipe's length.

[0004] Therefore, it is very necessary to invent a drainage pipe dredging device. Summary of the Invention

The components are easy to transport and easy to install in the well. They can penetrate the entire drainage pipe body 3. They can use water inside the pipe or external water source through the suction pipe 7 to perform high-pressure flushing inside the pipe. They can also flush the sludge after flushing in a certain direction and let it flow into the water collection component 10 at one end. The distance of the sludge flushing component 12 can also be adjusted according to the pipe diameter.

[0048] Each sliding component 5 includes an arc-shaped cover 14, with multiple circular holes 20 inside. These holes are designed to allow the entire device to be lifted using hooks or other external objects for easy operation.

For safety, a fixing rod 15 is provided at the lower part of the arc-shaped cover 14, and a limit rod 16 is bolted to the upper outer side of the fixing rod 15 for limiting its position. A fixing cone 17 is welded to the lower end of the fixing rod 15 for further adjustment. The device is fixed by inserting and sliding a sleeve 18 is slidably sleeved on the outer wall of the fixing rod 15. A tray 19 is bolted to the upper part of the inner side of the sliding sleeve 18, which can move freely up and down to meet the dredging requirements.

The fixed ring 21 is attached to the outside of the sliding assembly 5 on the right side.

[0050] In this implementation plan, in conjunction with the appendix Figure 5 To be continued Figure 7 As shown, the connecting component 11 includes a middle connecting rod 26. The middle connecting rod 26 has threads on both the left and right sides and is connected to left and right connecting rods 25. The middle connecting rod 26 has grooves 27 on both the front and rear sides and has locking chains 28 inside the grooves 27 to fix the left and right connecting rods 25. The length of the left and right connecting rods 25 and the middle connecting rod 26 after connection is set to 1-1.5 meters to ensure connection stability and avoid disengagement during rotation. It can be arbitrarily combined according to the length of the drainage pipe body 3, and is convenient for transportation and installation in the well. It can penetrate the entire drainage pipe body 3. The left connecting rod of the left and right connecting rods 25 is connected to the right bearing of the high-pressure flushing pump 6 housing, and the right end of the right connecting rod is connected to the left end of the output shaft of the rotating machine 8.

[0051] In this implementation plan, in conjunction with the appendix Figure 8 As shown, the dredging and flushing assembly 12 includes a ring 29. Telescopic rods 30 are bolted to the left and right sides of the lower part of the ring 29. A high-pressure flushing nozzle 31 is bolted to the outer end of each telescopic rod 30. The telescopic rods 30 are made of three-stage stainless steel, allowing for adjustment of the high-pressure flushing nozzle 31 according to the pipe diameter, thus ensuring the dredging and flushing effect. The ring 29 consists of multiple hollow stainless steel rings, which are fitted onto the outer walls of the left and right connecting rods 25 and the middle connecting rod 26, with fastening bolts at the connection points. The high-pressure flushing nozzle 31 is connected to the high-pressure flushing pump 6 via a pipeline. A rotatable universal joint is provided at the pipeline connection between the high-pressure flushing nozzle 31 and the high-pressure flushing pump 6. The distance of the dredging and flushing assembly 12 can also be adjusted according to the pipe diameter. For difficult-to-flushed areas, the toughness of the dredging and flushing assembly 12 can be used to break up and loosen the debris.

[0052] In this implementation plan, in conjunction with the appendix Figure 9As shown, the lifting assembly 13 consists of two components, each including a lifting motor 32. A worm gear reducer 33 is bolted to the lower part of each lifting motor 32, and a winding wheel 34 is keyed to the outer wall of the front end of the output shaft of each worm gear reducer 33. A lifting rope 35 is wound around the outer wall of each winding wheel 34, and a lifting seat 36 is attached to the lower end of each lifting rope 35. The inner end of the lifting seat 36 is bolted to the upper part of the outer side of the sliding sleeve 18. The lifting rope 35 also penetrates the interior of the manhole cover 2. A transmission connection is established between the lifting motor 32 and the worm gear reducer 33, with the worm gear reducer 33 bolted to the outer part of the upper part of the manhole cover 2. This increases the lifting function, allowing for free adjustment of height as needed, thus ensuring the dredging effect and meeting requirements. The external power line 9 provides power to both the lifting motor 32 and the high-pressure flushing pump 6, ensuring the stability of the equipment operation.

[0053] The working process of this invention is as follows: The sliding sleeve 18 drives the tray 19 to move up and down on the outer wall of the fixed rod 15, adjusting the position of the high-pressure flushing pump 6 and the rotating machine 8 to facilitate sludge removal and flushing operations. The limiting rod 16 provides a limiting function. During sludge removal and flushing, larger debris and impurities can be collected through the water filter screen 22 to prevent pipe blockage. The chain 28 connects and fixes the left and right connecting rods 25 and the middle connecting rod 26 to prevent rotational disengagement. The high-pressure flushing nozzle 31, in conjunction with the high-pressure flushing pump 6, enables high-pressure flushing and sludge removal operations. Rotation allows for large-area flushing and sludge removal of the inner wall of the pipe, improving sludge removal efficiency. Furthermore, the lifting motor 3... 2. The worm gear reducer 33 drives the winding wheel 34 to rotate, which allows the lifting rope 35 to drive the lifting seat 36 to drive the sliding sleeve 18 to drive the tray 19 to freely adjust up and down, thus ensuring convenient operation. This invention can be arbitrarily combined according to the length of the drainage pipe body 3, and is convenient to transport and install in the well. It can run through the entire drainage pipe body 3. It can use water inside the pipe or use external water source to perform high-pressure flushing inside the pipe through the suction pipe 7. It can also flush out the sludge after flushing in a certain direction and flow into the water collection component 10 at one end. The distance of the sludge cleaning and flushing component 12 can also be adjusted according to the pipe diameter. For parts that are difficult to clean, the toughness of the sludge cleaning and flushing component 12 can be used to break up and loosen them.
