Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, and specifically relates to a conduit cleaning device for water conservancy projects. Background Technology

[0002] Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluices, intakes, canals, ferries, rafts, and fishways, to achieve their objectives. Pipelines play a crucial role in the construction and operation of these projects, for example, in transporting water, slurry, and other media. However, over time, various conduits accumulate inside, such as silt, scale, and rust. Therefore, regular cleaning of the conduits using cleaning devices is necessary. Traditional pipe cleaning devices primarily use rotating cleaning heads to drive brushes that clean the inner walls of the pipes, removing the dirt. However, traditional pipe cleaning devices are difficult to adapt to pipes of different diameters and can only clean pipes of the same inner diameter. Cleaning pipes of other inner diameters requires changing to different sized cleaning heads, which is time-consuming and labor-intensive. Furthermore, having different sized cleaning heads on hand increases costs.

[0003] Existing water conservancy pipes are generally cleaned by high-pressure nozzles to clean their inner walls. However, the spray angle of the high-pressure nozzles is fixed, which means that the inner walls of the pipes cannot be completely cleaned. Although some cleaning devices use water pressure adaptive positioning frames to adjust the position of the nozzles, the lack of a linkage structure between each adjustment frame results in different extension lengths for each frame. This leads to uneven cleaning efficiency in different areas and requires more cleaning time.

[0004] Therefore, there is an urgent need to provide a pipe cleaning device for water conservancy projects to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a conduit cleaning device for water conservancy projects.

[0006] The technical solution adopted to solve the above technical problems is: a pipe cleaning device for water conservancy projects, including a rotating sleeve, wherein a rotating chamber is fixed at the bottom end of the rotating sleeve; The bottom end of the rotary chamber is fixed with a telescopic sleeve by bolts, the bottom end of the telescopic sleeve is fixed with a first mounting shell, and the bottom end of the first mounting shell is fixed with a second mounting shell by bolts. The rotating sleeve and telescopic sleeve are equipped with a rotating mechanism that performs rotary scanning spraying through water flow. The telescopic sleeve, the first mounting shell and the second mounting shell are equipped with an adjustment mechanism that automatically centers the pipe according to its actual diameter or shape.

[0007] Furthermore, the rotating mechanism includes a water pipe shaft rotatably installed inside the rotating sleeve. A shaft sealing ring is fixed to the outside of the water pipe shaft, and the outside of the shaft sealing ring is sealed to the inside of the rotating sleeve. A hydraulic impeller is fixed to the bottom end of the water pipe shaft, and the outside of the hydraulic impeller is tightly fitted to the inside of the impeller chamber. The bottom end of the hydraulic impeller is rotatably connected to the top end of the telescopic sleeve.

[0008] Through the above technical solution, when water flows through the impeller chamber into the water pipe shaft inside the rotating sleeve, the water flow drives the hydraulic impeller to rotate, and the hydraulic impeller drives the water pipe shaft to rotate accordingly. At the same time, the sealing connection between the shaft sealing ring and the rotating sleeve, as well as the tight fit between the hydraulic impeller and the impeller chamber, effectively prevent water leakage and ensure the stability and reliability of the entire rotating mechanism during operation. In addition, the rotating connection between the hydraulic impeller and the top of the telescopic sleeve provides good support and guidance for the entire rotation process.

[0009] Furthermore, an installation sleeve is fixed to the top of the water pipe shaft, and positioning strips are fixed to both sides of the installation sleeve. A high-pressure nozzle is fitted onto the outside of the installation sleeve and the two positioning strips.

[0010] With the above technical solution, when water flows into the high-pressure nozzle through the water pipe shaft, the water is pressurized and sprayed out at high speed. At the same time, the water pipe shaft drives the high-pressure nozzle to rotate automatically through the positioning strip on it. This rotation mechanism allows the high-pressure nozzle to maintain a constant rotation speed as it moves along the pipe with the entire cleaning device, performing scanning spraying operations. This ensures that every part of the inner wall of the pipe is effectively impacted by the water flow, thereby achieving a uniform and comprehensive cleaning effect.

[0011] Furthermore, a fixing bolt with one end penetrating and extending into the interior is threaded on both sides of the high-pressure nozzle, a fixing groove is provided inside the positioning strip to engage with the fixing bolt, and a water inlet pipe is fixed to the outside of the telescopic sleeve.

[0012] With the above technical solution, when it is necessary to install a high-pressure nozzle, the operator only needs to align the fixing bolt with the fixing groove on the positioning strip, and then rotate the fixing bolt to make its threaded connection in place, thus completing the installation of the high-pressure nozzle. Similarly, when it is necessary to disassemble the high-pressure nozzle, simply rotate the fixing bolt in the opposite direction to loosen it from the fixing groove, and the high-pressure nozzle can be easily removed.

[0013] Furthermore, the adjustment mechanism includes a first adjustment shaft bracket slidably installed inside the telescopic sleeve, a shaft bracket sealing ring fixed to the outside of the first adjustment shaft bracket, the outside of the shaft bracket sealing ring being sealed to the inside of the telescopic sleeve, and a second adjustment shaft bracket fixed to the bottom end of the first adjustment shaft bracket.

[0014] With the above technical solution, when water flows into the telescopic sleeve through the inlet pipe, the water pressure will drive the first and second adjusting shafts to move through the telescopic sleeve.

[0015] Furthermore, three first adapter rods are rotatably mounted inside the first mounting shell. One end of each of the three first adapter rods is fixed with a first adjusting rod. The interior of the first adjusting shaft bracket is provided with three first sliding grooves. The interiors of the three first sliding grooves are adaptively and slidably connected to the exteriors of the three first adjusting rods. The other end of each of the three first adapter rods is rotatably mounted with a first moving wheel.

[0016] Through the above technical solution, the first adjusting shaft frame drives the first adapter rod to rotate through the first adjusting rod, so that the first moving wheel of the first adapter rod contacts the inner wall of the pipe.

[0017] Furthermore, three second adapter rods are rotatably mounted inside the second mounting housing. One end of each of the three second adapter rods is fixed with a second adjusting rod. The interior of the second adjusting shaft bracket is provided with three second sliding grooves. The interiors of the three second sliding grooves are adaptively and slidably connected to the exteriors of the three second adjusting rods. The other end of each of the three second adapter rods is rotatably mounted with a second moving wheel.

[0018] Through the above technical solution, the second adjusting rod drives the second adapter rod to rotate, so that the second moving wheel of the second adapter rod contacts the inner wall of the pipe.

[0019] The beneficial effects of this invention are as follows: (1) By providing an adjustment mechanism, when the cleaning device is running in the pipe, the axial pressure generated by the water flow acts on the adjustment mechanism, causing the included angle between the first adapter rod and the second adapter rod to change adaptively, so that the high-pressure nozzle can automatically center according to the actual diameter or shape of the pipe, ensuring that the nozzle is always in the best working position, effectively improving the adaptability to irregular or variable diameter pipes, and completing the attitude adaptive adjustment simultaneously without additional power supply or complex control system, which not only improves the reliability and environmental adaptability of the equipment, but also greatly reduces maintenance costs and energy consumption. (2) The present invention is equipped with a rotating mechanism. The hydraulic rotor can receive the impact of high-speed water flow to generate rotational power. The hydraulic rotor is connected to the high-pressure nozzle through a transmission component, which drives the entire high-pressure nozzle to rotate continuously around the pipeline axis. This allows the high-pressure nozzle to perform constant rotary scanning spray while moving forward with the device, significantly expanding the cleaning coverage area, eliminating the blind spot problem of traditional fixed-angle nozzles, and achieving uniform and comprehensive cleaning of the pipeline inner wall.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] like Figures 1-7As shown, this embodiment of a conduit cleaning device for hydraulic engineering includes a rotating sleeve 1, with a rotating chamber 2 fixed to the bottom end of the rotating sleeve 1; a telescopic sleeve 3 is bolted to the bottom end of the rotating chamber 2, a first mounting shell 4 is fixed to the bottom end of the telescopic sleeve 3, and a second mounting shell 5 is bolted to the bottom end of the first mounting shell 4; a rotating mechanism 6 is provided inside the rotating sleeve 1 and the telescopic sleeve 3 for rotary scanning spraying via water flow, the rotating mechanism 6 including a water pipe shaft 601 rotatably installed inside the rotating sleeve 1, and a rotating shaft fixed to the outside of the water pipe shaft 601. A sealing ring 602 is used, and its outer surface is sealed to the inside of the rotating sleeve 1. A hydraulic impeller 603 is fixed to the bottom end of the water pipe shaft 601. The outer surface of the hydraulic impeller 603 is tightly fitted to the inside of the impeller chamber 2. The bottom end of the hydraulic impeller 603 is rotatably connected to the top end of the telescopic sleeve 3. An installation sleeve 604 is fixed to the top end of the water pipe shaft 601. Positioning strips 605 are fixed to both sides of the installation sleeve 604. A high-pressure nozzle 606 is fitted onto the outside of the installation sleeve 604 and the two positioning strips 605. Both sides of the high-pressure nozzle 606 are threaded. A fixing bolt 607 extends through and into the interior of the telescopic sleeve 3. A fixing groove is provided inside the positioning strip 605 to engage with the fixing bolt 607. A water inlet pipe 608 is fixed to the outside of the telescopic sleeve 3. The water inlet pipe 608 is connected to an external water source via a flexible hose. When the water source is turned on, the water flows sequentially through the telescopic sleeve 3 and the impeller chamber 2 into the water pipe shaft 601. Under the impact of the water flow, the hydraulic impeller 603 begins to rotate, thereby driving the water pipe shaft 601 to rotate. Simultaneously, the water flows upward along the water pipe shaft 601 and finally enters the high-pressure nozzle 6. 06. Due to the rotation of the water pipe shaft 601, the high-pressure nozzle 606 is driven to rotate synchronously through the positioning strip 605. This allows the high-pressure nozzle 606 to perform a constant-speed rotary scanning spray as it moves along the pipe, evenly spraying high-pressure water onto the inner wall of the pipe to achieve a thorough cleaning of the inner wall. When maintenance or replacement of the high-pressure nozzle 606 is required, simply use a tool to unscrew the fixing bolts 607 on both sides to remove the high-pressure nozzle 606 from the positioning strip 605, perform the corresponding operation, and then reinstall it in reverse order.

[0024] like Figures 3-6As shown, the telescopic sleeve 3, the first mounting shell 4, and the second mounting shell 5 are equipped with an adjustment mechanism 7 that automatically centers the pipe according to its actual diameter or shape. The adjustment mechanism 7 includes a first adjustment shaft bracket 701 slidably installed inside the telescopic sleeve 3. A shaft bracket sealing ring 702 is fixed to the outside of the first adjustment shaft bracket 701, and the outside of the shaft bracket sealing ring 702 is sealed to the inside of the telescopic sleeve 3. A second adjustment shaft bracket 703 is fixed to the bottom end of the first adjustment shaft bracket 701. Three first adapter rods 704 are rotatably installed inside the first mounting shell 4. A first adjustment rod 705 is fixed to one end of each of the three first adapter rods 704. Three first sliding grooves are provided inside the first adjustment shaft bracket 701, and the interiors of the three first sliding grooves are adaptively slidably connected to the exteriors of the three first adjustment rods 705. A first moving wheel 706 is rotatably installed at the other end of each of the three first adapter rods 704. Three second adapter rods 707 are rotatably installed inside the second mounting shell 5. A second adjustment rod 705 is fixed to one end of each of the three second adapter rods 707. 8. The interior of the second adjusting shaft bracket 703 is provided with three second sliding grooves. The interior of the three second sliding grooves is adaptively and slidingly connected to the exterior of the three second adjusting rods 708. The other end of each of the three second adjusting rods 707 is rotatably mounted with a second moving wheel 709. Water flows into the telescopic sleeve 3 through the water inlet pipe 608. As the water flows in continuously, the water pressure gradually increases, pushing the first adjusting shaft bracket 701 and the second adjusting shaft bracket 703 to move along the telescopic sleeve 3. During this process, the movement of the first adjusting shaft bracket 701 drives the first adjusting rod 705 to move, which in turn causes the first adjusting rod 704 to rotate around its axis, ultimately making the first moving wheel 706 in close contact with the inner wall of the pipe. At the same time, the movement of the second adjusting shaft bracket 703 also causes the second adjusting rod 708 to move, thereby driving the second adjusting rod 707 to rotate, so that the second moving wheel 709 also comes into contact with the inner wall of the pipe. In this way, according to the specific application scenario and needs, the automatic experimental adjustment of the internal structure of the pipe is realized by using water pressure drive.

[0025] The working principle of this embodiment is as follows: the inlet pipe 608 is connected to an external water source via a flexible hose. When the water source is turned on, water flows through the inlet pipe 608 into the telescopic sleeve 3. As the water flows in continuously, the water pressure gradually increases, pushing the first adjusting shaft 701 and the second adjusting shaft 703 to move along the telescopic sleeve 3. During this process, the movement of the first adjusting shaft 701 drives the first adjusting rod 705 to move, thereby causing the first adapter rod 704 to rotate around its axis, ultimately making the first moving wheel 706 in close contact with the inner wall of the pipe. At the same time, the movement of the second adjusting shaft 703 also causes the second adjusting rod 708 to move, thereby driving the second adapter rod 707 to rotate, allowing the second moving wheel 709 to also contact the inner wall of the pipe. In this way, according to specific application scenarios and needs, water pressure is used to realize the automatic experimental adjustment of the internal structure of the pipe. Simultaneously, water flows through the telescopic sleeve 3 and the impeller chamber 2 into the water pipe shaft 601. Under the impact of the water flow, the hydraulic impeller 603 begins to rotate, which in turn drives the water pipe shaft 601 to rotate. At the same time, the water flows upward along the water pipe shaft 601 and finally enters the high-pressure nozzle 606. Due to the rotation of the water pipe shaft 601, the high-pressure nozzle 606 rotates synchronously through the positioning strip 605. This allows the high-pressure nozzle 606 to perform a constant-speed rotary scanning spray as it moves along the pipe, evenly spraying high-pressure water onto the inner wall of the pipe to achieve a thorough cleaning of the inner wall. When maintenance or replacement of the high-pressure nozzle 606 is required, simply use tools to unscrew the fixing bolts 607 on both sides to remove the high-pressure nozzle 606 from the positioning strip 605, perform the corresponding operation, and then reinstall it in reverse order.
