Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water purification device for water conservancy projects. Background Technology

[0002] In water conservancy projects, water often needs to be discharged. The discharged water often contains a large amount of sewage and silt, which can easily cause blockages. Most water conservancy projects use drainage ditches to divert water to areas outside of roadbeds and residential areas.

[0003] According to announcement number CN221702646 U, a water purification device for water conservancy projects is disclosed. This patent uses a sludge scraper and a transmission belt to scrape the silt on the inner wall into a pull-out frame inside the sludge collection box, solving the problems of complex structure and poor cleaning effect of silt sediment removal in water conservancy projects. However, during the movement of the sludge scraper, the silt is squeezed, causing it to be squeezed into the through holes of the grid plate, thus affecting the subsequent filtration effect of the grid plate. In addition, when the sludge scraper moves towards the center, the water leakage hole at the top will be discharged from one side of the sludge scraper, causing the grid plate to lose its filtration effect and affecting actual use.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model is constructed by setting up a bidirectional lead screw, a sludge scraper, a guide rod, a rotating plate, a sliding groove, a sliding rod, and a limiting groove. The bidirectional lead screw is rotated by a motor, causing the sludge scrapers on both sides to move on the surface of the guide rod. During the movement of the sludge scrapers, the rotating plate is driven to move the sliding rod within the sliding groove. With the cooperation of the arc-shaped limiting groove, the rotating plate rotates towards the sludge scraper.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a water purification device for water conservancy projects, including a shell 1, the upper surface of which is welded and fixed to a leaking plate 2, the shell 1 being hollow inside, a rectangular through hole at the bottom of which communicates with a sludge discharge port 12, one end of which is welded and fixed to a filter plate 3, the side of which is connected and fixed to a motor 4 by bolts, the output end of which is welded and fixed to a bidirectional lead screw 5, a sludge scraper 6 being provided on the outside of the bidirectional lead screw 5, one end of which is welded and fixed to the inner wall of the shell 1, and the sludge scraper 6 being hinged to the side of a rotating plate 8. A sliding groove 9 is formed on the side of plate 8, and a sliding rod 10 is installed inside the sliding groove 9. A limiting groove 11 is formed on the inner wall of the housing 1. The bottom of the housing 1 is welded and fixed to the sludge discharge port 12. The sludge discharge port 12 is movably inserted into the collection box 13. A sealing ring is set on the side of the collection box 13, and the sealing ring is located at the connection between the sludge discharge port 12 and the collection box 13. A slot 14 is formed on the top of the collection box 13. A rectangular groove 15 is formed on the side of the housing 1. A movable plate 16 is installed inside the rectangular groove 15. The rectangular groove 15 is fixedly connected to a spring 17. The movable plate 16 is welded and fixed to one end of the locking plate 18.

[0021] One end of the bidirectional lead screw 5 is rotatably connected to the inner wall of the housing 1. Opposite threads are provided on both sides of the bidirectional lead screw 5. Two scraper frames 6 are symmetrically distributed on both sides of the bidirectional lead screw 5. The scraper frames 6 are connected to the outer threads of the bidirectional lead screw 5 through threaded holes. Since filter plates 3 are provided at both ends of the housing 1, water entering through the filter plates 3 can be filtered and discharged from both sides, improving filtration efficiency. The motor 4 rotates the bidirectional lead screw 5, causing the scraper frames 6 on both sides to move towards each other on the surface of the guide rod 7. This fixes the position of the filter plates 3. Therefore, even when the motor 4 rotates to clean the mud and sand, the filter plates 3 still provide a filtering effect.

[0022] As the scraper 6 moves, the slide rod 10 slides inside the limiting groove 11. The limiting groove 11 is an arc-shaped groove, allowing the slide rod 10 to slide inside the sliding groove 9. This causes the rotating plate 8 to rotate around the bottom hinge axis towards the scraper 6. The scraper 6 scrapes away the mud and sand from the inner wall of the housing 1, while the rotating plate 8 pushes the mud and sand forward. There are gaps between the two sides of the rotating plate 8 and the scraper 6. Therefore, when the scraper 6 moves, water will be above the mud and sand and will be discharged through the gaps to be filtered by the filter plate 3. The mud and sand, blocked by the scraper 6 and the rotating plate 8, will be pushed into the mud discharge port 12. The original water inside the mud discharge port 12 will overflow, thus filling the bottom of the collection box 13 with mud and sand.

[0023] A rectangular through hole is provided in the center of the scraper frame 6. The scraper frame 6 is hinged to the side of the rotating plate 8 via a hinge shaft. Sliding grooves 9 are provided on both sides of the rotating plate 8. The sliding rod 10 is slidably connected to the interior of the sliding grooves 9. The limiting groove 11 consists of an arc-shaped groove section and a straight groove section, with both ends of the straight groove section connected to the arc-shaped groove section. The limiting groove 11 is slidably connected to the sliding rod 10. The arc-shaped limiting groove 11 allows the sliding rod 10 to slide within the sliding groove 9, enabling the rotating plate 8 to rotate towards the scraper frame 6 with the bottom hinge shaft as the center. The sliding rod 10 in the arc-shaped groove section of the limiting groove 11 drives the rotating plate 8 to rotate, forming a push plate in conjunction with the scraper frame 6. The straight groove section of the limiting groove 11 limits the rotation of the rotating plate 8, preventing it from rotating off-center.

[0024] Spring 17 and locking plate 18 are located on both sides of movable plate 16. Movable plate 16 is slidably connected to rectangular groove 15. The bottom of locking plate 18 extends to the bottom of housing 1 and is movably inserted into locking groove 14.

[0025] Working principle: When in use, water enters the housing 1 through the filter plate 3 and is then discharged after being filtered by the drain plates 2 on both sides. Impurities and silt in the water are filtered inside the housing 1. The motor 4 drives the bidirectional lead screw 5 to rotate, which drives the sludge scrapers 6 on both sides to move towards each other on the surface of the guide rod 7. While the sludge scrapers 6 are moving, the slide rod 10 slides inside the limiting groove 11. The limiting groove 11 is an arc groove, which allows the slide rod 10 to slide inside the sliding groove 9. This causes the rotating plate 8 to rotate around the bottom hinge shaft towards the sludge scraper 6. The sludge scraper 6 scrapes away the silt from the inner wall of the housing 1, and the rotating plate 8 pushes the silt forward until it is moved into the sludge discharge port 12. By pushing the moving plate 16 upward, the clamping plate 18 is disengaged from the clamping groove 14, and the collection box 13 can be pulled out from the sludge discharge port 12, thus cleaning up the silt and reducing the workload of the workers.
