[0028] 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.

[0029] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: a filtration device for sediment in water conservancy projects. The filtration device includes a clean water tank 1, a sediment tank 3 fixedly connected to the top front side of the clean water tank 1, a square groove 5 formed in the upper middle part of the front side of the sediment tank 3, a slider 6 slidably connected to the inner wall of the square groove 5, allowing the slider 6 to move within the square groove 5, a cylinder 7 fixedly connected to the left end of the slider 6, a block 8 fixedly connected to the bottom of the cylinder 7, and a mud-pushing plate 9 fixedly connected to the bottom right end of the block 8. The mud plate 9 is slidably connected to the front of the interior of the mud tank 3. A cleaning brush 10 is fixedly connected to the top left of the block 8. The bottom of the cleaning brush 10 is slidably connected to the front of the interior of the mud tank 3. A water control plate 13 is fixedly connected to the middle and rear of the inner wall of the mud tank 3. A water flow hole 4 is opened on the rear side of the mud tank 3. A square groove 11 is opened on the lower right side of the mud tank 3. A square plate 12 is slidably connected inside the square groove 11. A speed control mechanism 2 for controlling the water flow is rotatably connected to the bottom of the rear side of the mud tank 3.

[0030] In addition, handles 16 are fixedly connected to the left and right sides of the water tank 1, and filter plate 15 is fixedly connected to the upper part of the inner wall of the water tank 1.

[0031] In this embodiment, it should be noted that the user can inject mud and water into the mud and water tank 3. When the mud and sand clump together or large particles accumulate at the bottom front side of the mud and water tank 3, first stop injecting water, then push the cylinder 7 to the right by hand. As the cylinder 7 moves, it will drive the block 8 to move to the right, and then the block 8 will drive the mud-pushing plate 9 to move to the right. When the mud-pushing plate 9 moves to the right, it will drive the mud and sand to move, thus cleaning out the large particles and clumps of mud and sand from the mud and water tank 3. At the same time, the cleaning brush 10 will brush the bottom when the block 8 is pushed to the right, which can prevent it from entering the filter plate 15 and causing blockage.

[0032] Example 2, based on Example 1, such as Figure 2 , Figure 4 and Figure 5 As shown, the speed control mechanism 2 in this embodiment is used to control the water flow. As an example of controlling the water flow, in this embodiment, the speed control mechanism 2 includes a rotating rod 201, a long plate 202 is fixedly connected to the outer wall of the rotating rod 201, a flow control column 203 is fixedly connected to the top of the long plate 202, a baffle 204 is fixedly connected to the top of the long plate 202, a round block 205 is fixedly connected to the left side of the rotating rod 201, and a handle 206 is fixedly connected to the left side of the round block 205.

[0033] In addition, handles 16 are fixedly connected to the left and right sides of the water purification tank 1. A circular groove 17 is formed in the middle of the rear side of the water purification tank 1, and a filter plate 18 is fixedly connected to the front side of the inner wall of the circular groove 17. A circular cover 19 is slidably connected to the rear side of the inner wall of the circular groove 17, and a handle 20 is fixedly connected to the rear side of the circular cover 19. An anti-slip sleeve 21 is fixedly connected to the outer wall of the handle 20, and a circular cover 14 is slidably connected to the front side of the mud water tank 3.

[0034] In this embodiment, it should be noted that the user can adjust the water flow rate through the speed control mechanism 2. For example, when the water flow rate is too high, the user can rotate the handle 206 to make the round block 205 rotate downward, which in turn drives the rotating rod 201 to rotate downward. As the rotating rod 201 rotates downward, the long plate 202 will rotate downward, thereby adjusting the tilt angle, reducing the water flow rate and the water volume.

[0035] Working principle: The mud and water to be filtered are injected into the front inner wall of the mud and water tank 3. When mud and sand clump together or large particles accumulate at the bottom of the front side of the mud and water tank 3, the water injection is stopped. At this time, the cylinder 7 is pushed to the right. When the cylinder 7 is pushed to the right, it drives the block 8 to move to the right. The movement of the block 8 to the right will drive the mud-pushing plate 9 to move to the right. The movement of the mud-pushing plate 9 to the right will dislodge the mud and sand at the bottom of the mud and water tank 3. Then, the square plate 12 is moved to clean out the large particles and clumps of mud and sand from the mud and water tank 3. The cleaning brush 10, which is fixed to the left side of the block 8, will brush the bottom when the block 8 is pushed to the right. This prevents the mud and sand from entering the filter plate 15 and causing blockage, improves the filtration effect, reduces the cleaning steps, saves time and costs, maintains the permeability of the filter medium, improves the filtration efficiency, and reduces the frequency of manual cleaning and equipment wear and tear.

[0036] When the water flow velocity is too high, turn handle 206 downwards. When handle 206 turns downwards, it will cause the circular block 205 to turn downwards. The downward rotation of the circular block 205 will cause the rotating rod 201 to turn downwards. The downward rotation of the rotating rod 201 will cause the long plate 202 to turn downwards, reducing the tilt angle. In this way, the water flows to the filter plate 15 for filtration along the path formed by the flow control column 203. This reduces the water flow velocity and flow rate, prolongs the contact time between the sediment and the filter medium, improves the filtration accuracy, reduces the loss of the medium, avoids the re-suspension of sediment, and balances the filtration load.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
