[0021] In the following description, embodiments of the hydraulic pipe outlet sediment filtration structure of this utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-5This invention illustrates a sediment filtration structure for a water pipe inlet according to an embodiment of the present invention. It includes a fixed sleeve 2 fitted onto the surface of a water pipe 1. The fixed sleeve 2 is fixedly connected to the water pipe 1. A filter plate 3 is provided on the surface of the inlet of the water pipe 1, located within the cavity of the fixed sleeve 2. The filter plate 3 has several circular filter holes 4 and grooves 5. A movable plate 6 is provided within the cavity of the water pipe 1. Several transverse pins 7 are fixedly connected to the surface of the movable plate 6, and the pins 7 are adapted to the filter holes 4. A movable rod 8 is fixedly connected to the surface of the movable plate 6. A limiting sleeve 15 is fitted onto the surface of the movable rod 8, and the limiting sleeve 15 is fixedly connected to the movable rod 8. A rotating sleeve 13 is fitted onto the surface of the movable rod 8. Through the coordinated use of the rotating sleeve 13, the scraper 14, and the limiting sleeve 15, when water flows through the filter holes 4 into the water pipe 1, the scraper 14 is impacted by the water flow. Force causes the scraper 14 to rotate through the limiting sleeve 15, thereby moving the scraper 14 on the surface of the filter plate 3, which facilitates the scraping of some mud and sand on the surface of the filter plate 3. The rotating sleeve 13 is rotatably connected to the movable rod 8. The scraper 14 is fixedly connected to the surface of the rotating sleeve 13. The scraper 14 is in contact with the surface of the filter plate 3. The scraper 14 is inclined. The reinforcing plate 16 is inclined. The movable rod 8 passes through the slot 5 and is adapted to the slot 5. One end of the movable rod 8 is fixedly connected to the fixing plate 9. Two symmetrical reinforcing plates 16 are fixedly connected to the surface of the fixing plate 9. The reinforcing plates 16 are fixedly connected to the connecting plate 10. Both sides of the fixing plate 9 are fixedly connected to the connecting plate 10. The surface of the connecting plate 10 is fixedly connected to the fixing block 11. Two symmetrical waterproof cylinders 12 are fixedly installed on the top of the fixing sleeve 2. The output end of the waterproof cylinder 12 is fixedly connected to the fixing block 11.

[0023] Working principle: When using this utility model, the user starts the waterproof cylinder 12, causing the output end of the waterproof cylinder 12 to drive the fixed block 11 forward, which in turn drives the connecting plate 10 forward, which in turn drives the fixed plate 9 forward, which in turn drives the movable rod 8 forward. At this time, the movable rod 8 drives the movable plate 6 forward, which in turn drives the ejector pin 7 to move towards the filter hole 4, so that the ejector pin 7 penetrates the filter hole 4, thereby pushing out the mud and sand inside the filter hole 4. This achieves the purpose of cleaning out most of the mud and sand in the filter hole, thus effectively reducing the risk of filter hole blockage. Through the coordinated use of the rotating sleeve 13, scraper 14 and limiting sleeve 15, when water flows through the filter hole 4 into the water pipe 1, the scraper 14 is subjected to the impact force of the water flow, which causes the scraper 14 to drive the rotating sleeve 13 to rotate through the limiting sleeve 15, so that the scraper 14 moves on the surface of the filter plate 3, thus facilitating the scraping of some mud and sand on the surface of the filter plate 3.

[0024] In summary, this water pipe inlet sediment filtration structure, by activating the waterproof cylinder 12, causes the output end of the waterproof cylinder 12 to drive the fixed block 11 forward, which in turn drives the fixed plate 9 forward via the connecting plate 10. This, in turn, causes the fixed plate 9 to drive the movable rod 8 forward, which in turn drives the ejector pin 7 on the surface of the movable plate 6 to move towards the filter hole 4. This allows the ejector pin 7 to penetrate the filter hole 4, thereby pushing out the sediment inside the filter hole 4. This achieves the goal of cleaning out most of the sediment inside the filter hole, thus effectively reducing the risk of filter hole blockage.
