[0002] Pre-buried water pipes are widely used in water conservancy projects, especially those penetrating walls. These pipes, installed in advance, facilitate water transport, effectively preventing later damage to building structures and playing a crucial role in connecting water conservancy facilities with buildings. However, the built-in filters in traditional penetrating wall pipes are prone to clogging by silt and debris in the water over long-term use, significantly reducing water flow efficiency and even affecting the normal operation of the entire water conservancy system. Furthermore, traditional pre-buried pipes lack effective clogging monitoring mechanisms, making it difficult to detect filter blockages in a timely manner and hindering timely cleaning measures by staff.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] Combined with appendix Figure 1 To be continued Figure 5 An anti-clogging device for a pre-buried water conservancy pipeline includes a pipeline body 1, with an inlet 2 at one end and an outlet 3 at the other end. A rotating filter assembly 4 for intercepting debris is located inside the pipeline body 1 near the inlet 2. A drive mechanism for rotating the rotating filter assembly 4 is provided on the pipeline body 1. A scraper 6 for peeling off deposits from the filter surface is fixedly installed on the inner wall of the pipeline body 1, and the scraper 6 contacts the outer surface of the rotating filter assembly 4. A collection trough 7 for collecting the peeled debris is located at the bottom of the pipeline body 1. Pressure sensors 8 are fixedly installed on the inner wall of the pipeline body 1 and on both sides of the rotating filter assembly 4. The device also includes a PLC controller 15, with the pressure sensors 8 and the drive mechanism electrically connected to the PLC controller 15.
[0023] The inner wall of the pipe body 1 is provided with an annular mounting groove 9, and the rotating filter assembly 4 is embedded in the mounting groove 9 through a bearing 10. The rotating filter assembly 4 includes an inner support frame 41 and an outer filter 42 arranged coaxially. The inner support frame 41 is connected to a drive mechanism through a transmission shaft 11. The drive mechanism includes a motor 5 fixed to the outer wall of the pipe body 1. The motor 5 is drivenly connected to the transmission shaft 11 through a waterproof sealing sleeve 12.
[0024] The scraper 6 is made of elastic rubber, and its contact surface with the rotating filter assembly 4 has a serrated structure. The end of the sludge collection tank 7 that extends to the outside of the pipe body 1 is connected to a sedimentation box 13. The bottom of the sedimentation box 13 is equipped with a drain valve 14, and the lower end of the sludge collection tank 7 is equipped with a valve 16.
[0025] The working principle of this utility model is as follows: This anti-clogging device for pre-buried water pipes works based on the principle of combining pressure monitoring and mechanical cleaning. The pressure sensor 8 monitors the pressure on both sides of the rotating filter assembly 4 in real time and transmits the data to the PLC controller 15. When the pressure difference exceeds the set threshold, it indicates that the filter is clogged. The PLC controller 15 controls the motor 5 to drive the rotating filter assembly 4 to rotate, and the scraper 6 removes the adhering substances from the surface of the filter. The debris falls into the collection tank 7 and is transported to the sedimentation tank 13, realizing automatic monitoring and cleaning to ensure unobstructed pipeline flow.
[0026] The working process of this utility model is as follows:
[0027] 1. Initial Operation: Water flows into the main body of the pipe 1 through the inlet 2, passes through the rotating filter assembly 4, and the inner support frame 41 and the outer filter 42 intercept impurities in the water. Clean water flows out from the outlet 3. At this time, the pressure sensor 8 monitors the pressure on both sides of the rotating filter assembly 4 in real time and transmits the data to the PLC controller 15.
[0028] 2. Clogging Monitoring: As the filter is used, debris gradually adheres to the surface of the rotating filter assembly 4, increasing the resistance to water flow and gradually raising the pressure difference between the two sides of the rotating filter assembly 4. When the pressure difference detected by the pressure sensor 8 reaches the preset threshold of the PLC controller 15, the PLC controller 15 determines that the filter is clogged.
[0029] 3. Automatic Cleaning: The PLC controller 15 issues a command to start the motor 5 fixed to the outer wall of the pipe body 1. The motor 5 drives the transmission shaft 11 to rotate through the waterproof sealing sleeve 12, which in turn drives the rotating filter assembly 4 to rotate in the annular mounting groove 9 through the bearing 10. During the rotation, the elastic rubber scraper 6, which is in contact with the outer surface of the rotating filter assembly 4, uses its serrated structure to peel off the adhering substances on the filter surface.
[0030] 4. Debris collection: The stripped debris falls into the sludge collection tank 7 at the bottom of the main pipe body 1 under the action of gravity. The sludge collection tank 7 transports the debris to the sedimentation box 13 that extends outside the main pipe body 1 for centralized collection.
[0031] 5. Sewage treatment: When the debris in the sedimentation tank 13 accumulates to a certain extent, close valve 16 and open drain valve 14 to discharge the debris; after cleaning, close drain valve 14 and then open valve 16 to restore the equipment to its initial operating state and continuously ensure the smooth flow of water in the main body of pipeline 1.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
