Description

Technical Field

[0001] This invention relates to the field of pipeline dredging technology, specifically to a pipeline dredging device for sewage treatment. Background Technology

[0002] Pipeline dredging refers to clearing silt and other waste from pipes to ensure they remain unobstructed and prevent urban flooding. Failure to regularly dredge pipes can lead to sewage overflow, environmental pollution, and disruption to daily life. Generally, dredging of the inner walls of water conservancy project pipes is done manually. This method requires a large workforce, increasing costs, time, and labor, and reducing efficiency. Furthermore, prolonged accumulation of silt and waste in water conservancy project pipes can produce toxic gases. Additionally, manual dredging is inconvenient if the pipe diameter is too small.

[0003] Currently, there are many dredging machines available. A search reveals that Chinese Patent Publication No. CN201711492835.3 discloses a dredging device for municipal sewer pipes. This device includes a support mechanism mounted on the ground of a vertical shaft, a dredging mechanism mounted on the support mechanism for cleaning silt, a propulsion mechanism mounted on the support mechanism, a collection mechanism mounted on the propulsion mechanism for collecting silt, a disassembly / assembly mechanism mounted on the support mechanism for cooperating with the propulsion mechanism, and a control mechanism mounted on the support mechanism for controlling the support mechanism, dredging mechanism, propulsion mechanism, collection mechanism, and disassembly / assembly mechanism. This invention not only avoids consuming large amounts of water but also efficiently cleans narrow underground pipes. Furthermore, by agitating the sewage and silt within the vertical shaft, it enables thorough dredging of the pipe.

[0004] The aforementioned patent has the following shortcomings: when performing pipeline dredging work, the propulsion mechanism encounters great resistance during the propulsion process when the diameter of the sewage pipe changes, making it difficult to move. Moreover, while moving, it pushes the sludge to a deeper position in the pipe. Therefore, in order to avoid the sludge at the bottom being pushed, we propose a pipeline dredging device for sewage treatment. Summary of the Invention

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-2 The present invention provides a technical solution: a pipe dredging device for sewage treatment, comprising a water pipe 1, and further comprising:

[0047] A connecting bearing 2 is installed on the outer wall of the water pipe 1. A moving mechanism 3 is installed on the outer wall of the connecting bearing 2 for moving the pipe cleaning device. The connecting bearing 2 is used to connect the moving mechanism 3 so that when the nozzle 8 sprays water and generates a spiral rotation, the bearing will rotate to prevent the moving mechanism 3 from rotating along with it.

[0048] Mounting ring 4 is fixedly sleeved on the outer wall of connecting bearing 2 and is used to connect water pipe 1 and moving mechanism 3;

[0049] Install the sleeve 9, which is inserted into the inner wall of the water pipe 1 to connect the nozzle 8;

[0050] Among them, the mobile mechanism 3 includes:

[0051] Adjustment tube 31 is disposed on the outer wall of mounting ring 4;

[0052] A fixed cylinder 38 is set on the outer wall of the regulating pipe 31, and the outer wall of the fixed cylinder 38 is provided with three through holes in an annular shape, and the inner wall of the through holes is movably connected to a first movable rod 35.

[0053] The adjusting plate 34 is connected to one end of the first movable rod 35, and its top is connected to the adjusting tube 31;

[0054] Pulley 37, connected to the other end of the first movable rod 35, is used for contact with the inner wall of the sewage pipe;

[0055] The first return spring 36 is sleeved on the outer wall of the first movable rod 35, and its two ends are respectively connected to the inner wall of the adjusting plate 34 and the fixed cylinder 38.

[0056] Please see Figure 3 An adjustment mechanism is provided on the outer wall of the adjustment tube 31 for moving the position of the adjustment tube 31;

[0057] The regulating mechanism includes:

[0058] An adjusting groove is formed in a ring on the inner wall of the fixed cylinder 38;

[0059] Three movable blocks 32, one end of each movable block 32 is fixedly connected to the outer wall of the regulating pipe 31, and the other end is slidably connected to the inner wall of the regulating groove. A round rod 33 is connected to the inner wall of each regulating groove and moves through the movable block 32.

[0060] One of the round rods 33 is rotatably connected to the inner wall of the adjusting groove via a bearing, and its outer wall has a threaded groove that threadedly passes through the movable block 32. When the movable block 32 rotates in the adjusting groove by rotating the round rod 33 with the threaded groove, under the limitation of the round rod 33 and the adjusting groove, it drives the movable block 32 to move within the adjusting groove, thereby driving the adjusting pipe 31 to move. In turn, the adjusting pipe 31 presses against the position of the adjusting plate 34, thereby changing the outward movement of the first movable rod 35 and changing the position of the pulley 37. This synchronously adjusts the contact between the three sets of pulleys 37 and the inner wall of the sewage pipe, providing stable support.

[0061] Please see Figure 3 The regulating pipe 31 is tapered, with its tapered tail located on one side of the regulating groove of the fixed cylinder 38. By setting the regulating pipe to a tapered shape, the position of the regulating pipe 31 within the fixed cylinder 38 is changed, thereby pressing the regulating plate 34 to change the position of the first movable rod 35 and the pulley 37, thus adapting to sewage pipes of different diameters.

[0062] Please see Figure 6 One end of the fixed cylinder 38 is connected to a scraper 7, which is used to scrape off the sludge deposited on the lower part of the inner wall of the sewage pipe;

[0063] The scraper 7 is fan-shaped with a hollow bottom opening. Three second movable rods 73 are mounted on the inner wall of the scraper 7, their tops extending outwards through the top of the inner wall. A movable scraper 71 is fixedly connected to the bottom of each second movable rod 73, located on the inner wall of the scraper 7. A spring 74 is fitted onto the outer wall of each second movable rod 73, with both ends contacting the scraper 7 and the movable scraper 71 respectively. An adjustable movable scraper 71 is installed inside the scraper 7. When the moving mechanism 3 moves into the sewage pipe, a gap remains between the bottom scraper 7 and the inner wall of the sewage pipe, preventing the sludge from being pushed. Once in the appropriate position, as the moving mechanism 3 moves outwards, the movable scraper 7 extends and contacts the bottom of the inner wall of the sewage pipe, thus scraping away the sludge adhering to the bottom of the pipe.

[0064] Please see Figure 4 An adjustment component 5 is provided on the regulating pipe 31 to change the position of the movable scraper 71 in contact with the inner wall of the sewage pipe;

[0065] Adjustment component 5 includes:

[0066] The adjusting rod 51 is connected to one end of the mounting ring 4, and the inner wall of the adjusting tube 31 is provided with a movable groove, and the outer wall of the adjusting tube 31 is provided with a slider, which is slidably connected to the inner wall of the movable groove to restrict the rotation of the adjusting tube 31.

[0067] An active hole is provided on the inner wall of the regulating tube 31, and a limit block 52 is provided at the opening to prevent the mounting ring 4 from disengaging from the regulating tube 31;

[0068] The U-shaped insert rod 53 has one end fixedly connected to the outer wall of the adjusting rod 51, and the other end inserted into the second movable rod 73 extending outward from the middle. The mounting ring 4 is placed on the inner wall of the adjusting pipe 31 and slids along its inner wall. The sliding block on the outer wall of the mounting ring 4 contacts the movable groove on the inner wall of the adjusting pipe 31, thus restricting the rotation of the mounting ring 4. By pulling the U-shaped insert rod 53, its contact state with the second movable rod 73 is changed, thereby adjusting the contact between the movable scraper 71 and the inner wall of the sewage pipe.

[0069] Please see Figure 5 The scraper 7 has a rectangular through hole on its side wall, and a lever 72 is provided on the outer wall of the scraper 7. The lever 72 passes through the rectangular through hole and is fixedly connected to the movable scraper 71. The lever 72 is provided on the outer wall of the scraper 7. By moving the lever, the movable scraper 71 can be pulled back to its original position. The movable scraper 71 can also be reset by inserting the movable U-shaped plug 53 into the second movable rod 73.

[0070] Please see Figure 4 A support mechanism 6 is provided at the inner wall end of the fixed cylinder 38 to support the regulating pipe 31 and improve the stability of the water pipe 1.

[0071] The support mechanism 6 includes a ring 61, which is connected to the inner wall of the fixed cylinder 38 and fixedly connected to the scraper 7 to improve the stability of the scraper 7.

[0072] Three sliding rods 62 are arranged in a ring and extend outward through the fixed cylinder 38. One end of each sliding rod 62 is fixedly connected to a support plate 64 and is connected to the outer wall of the adjusting pipe 31. A second return spring 63 is sleeved on the outer wall of the sliding rod 62, and its two ends are respectively connected to the support plate 64 and the fixed cylinder 38. A support mechanism 6 is provided at the end of the inner wall of the fixed cylinder 38. The second return spring 63 can then reset the support plate 64 to move towards the adjusting pipe 31, thereby supporting the adjusting pipe 31 and improving its stability. This makes the water pipe 1 more stable when moving within the moving mechanism 3.

[0073] Please see Figure 2-3 The nozzle 8 has a spray hole at its end, and its inner wall has several spiral grooves that communicate with the spray hole. By setting several spiral grooves in the nozzle 8 that communicate with the spray hole, when water is sprayed out of the nozzle through the water pipe 1, the nozzle 8 can rotate, which in turn can drive the water pipe 1 to move into the sewage pipe.

[0074] Please see Figure 3-4The tilt angles of the adjusting plate 34 and the support plate 64 are the same as the angle of the adjusting pipe 31, and both are in movable contact with the outer wall of the adjusting pipe 31. Setting the tilt angles of the adjusting plate 34 and the support plate 64 to be the same as the angle of the adjusting pipe 31 allows them to fit tightly against the outer wall of the adjusting pipe 31. This enables the adjustment of the positions of the first movable rod 35 and the pulley 37 to accommodate sewage pipes of different diameters, and also provides support to the outer wall of the adjusting pipe 31, improving its stability.

[0075] The working principle of this invention is as follows:

[0076] When cleaning sewage pipes, the cleaning device is placed at the cleaning location. Rotating the threaded rod 33 moves the movable block 32, pushing the adjusting pipe 31 connected to it. The pipe's conical outer wall contacts the adjusting plate 34, changing its diameter and thus pushing out the first movable rod 35. This causes the pulley 37 connected to the first movable rod 35 to contact the inner wall of the sewage pipe, achieving stable support and allowing the moving mechanism 3 to move stably within the sewage pipe. When cleaning a different section of sewage pipe with a changed diameter, rotating the adjusting rod 33 changes the position of the adjusting pipe 31. The first return spring 36 presses against the adjusting plate 34, moving the first movable rod 35 towards the adjusting pipe 31. This changes the position of the pulley 37 to accommodate the changed pipe diameter. Simultaneously, the second return spring 63 supports the moving support plate 64, providing stable support for the adjusting pipe 31 and improving its stability.

[0077] Water is then supplied to the water pipe by a water pump. The water is sprayed out through the nozzle via the spiral groove at the pump head, generating a spiral thrust. At the same time, the rotational force is counteracted by the connecting bearing 4, which drives the moving mechanism 3 to move deeper into the sewage pipe. After moving to the appropriate position, the water pipe 1 is pulled outward. At this time, the connecting bearing 2 and the mounting ring 4 connected to the outer wall of the water pipe 1 will move, thereby changing their position on the connecting pipe 31. This will drive the adjusting rod 51 to move, and then drive the U-shaped insert rod 53 to move, thereby changing the position of the second movable rod 73 connected to it. Under the action of the spring 74, the movable scraper 71 is pushed outward, and then comes into contact with the inner wall of the sewage pipe.

[0078] Then, when the water pipe 1 is pulled outward, the movable scraper 71 can scrape off the sludge at the bottom of the inner wall of the sewage pipe as it moves outward. At the same time, the water flow from the nozzle 8 at the water pipe 1 further flushes the inner wall of the sewage pipe, improving its sludge removal effect. After the sludge removal device is pulled out of the sewage pipe, the movable scraper 71 is moved by pulling the lever 72. Then, the movable U-shaped insert 53 is inserted into the second movable rod 73 and is stably fixed under the action of the spring 74.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
