The gravel treatment channel is located at the bottom of the floating debris treatment mechanism, and a barrier net is located at the lower end of the gravel treatment channel. The silt treatment mechanism is connected to the other end of the gravel treatment channel. The re-adsorption mechanism is located at the other end of the silt treatment mechanism, and a partition is provided at the connection between the re-adsorption mechanism and the silt treatment mechanism. The top of the partition is separated from the top wall of the re-adsorption mechanism, and an adsorption plate is located inside the re-adsorption mechanism. The driving mechanism is located outside the floating debris treatment mechanism. The water conservancy engineering filtration device provided by this invention has a simple structure and can effectively filter impurities in water, and the filtered impurities are easy to clean. However, in practical use, the existing technology still faces the problem that white pollution accounts for an increasing proportion of water body waste, and the filter screen is difficult to clean. Utility Model Content

[0003] Therefore, in response to the above problems, this utility model proposes a filtration device for water conservancy projects, which solves the technical problem that the proportion of white pollution in water body waste is increasing and the filter screen is difficult to clean in the actual use of existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a filtration device for water conservancy projects, the structure of which includes an inlet pipe, an inlet control valve, a drain pipe, a drain pipe cover, a closed garbage bin, a negative pressure pump, a filter, a fixed suction pipe, a movable suction pipe, and a filter screen. The inlet pipe is equipped with an inlet control valve, and the right end of the inlet pipe is connected to a vertically arranged drain pipe. The drain pipe cover is installed at the top of the drain pipe, and a filter screen is installed in the middle of the drain pipe cover. A closed garbage bin is installed next to the drain pipe, and a negative pressure pump is installed at the top of the closed garbage bin. A filter is installed at the front end of the negative pressure pump and is connected to the closed garbage bin. The closed garbage bin is also connected to a fixed suction pipe, and the front end of the fixed suction pipe is connected to the movable suction pipe through a movable connecting hose.

[0005] Furthermore, the filter screen is fixedly connected to the side wall of the drain pipe by bolts.

[0006] Furthermore, the diameter of the filter screen is at least three times the diameter of the inlet pipe.

[0007] Furthermore, the filter screen has a metal mesh structure, and the bottom of the filter screen is provided with reinforcing strips for support.

[0008] Furthermore, the side of the enclosed trash can is provided with a trash can door for removing trash, and the trash can door is sealed to the enclosed trash can by a sealing strip.

[0009] Furthermore, the movable straw is made of aluminum alloy and has a handle for easy gripping.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: The filtration device used in this water conservancy project improves upon the existing technology, which still faces the problem that white pollution accounts for an increasing proportion of waste in water bodies and that the filter screen is difficult to clean during actual use. In this solution, after the user opens the drain pipe cover, they start the negative pressure pump on the closed garbage bin, and then hold the movable suction tube to suck up the garbage on the filter screen to complete the cleaning of the filter screen surface. Afterwards, the garbage is stored in the closed garbage bin, and after several uses, the garbage can be transferred. Attached Figure Description

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0014] refer to Figure 1 This embodiment provides a filtration device for water conservancy projects. Its structure includes an inlet pipe 1, an inlet control valve 2, a drain pipe 3, a drain pipe cover 4, a closed garbage bin 5, a negative pressure pump 6, a filter 7, a fixed suction pipe 8, a movable suction pipe 9, and a filter screen 10. The inlet pipe 1 is equipped with the inlet control valve 2. The right end of the inlet pipe 1 is connected to the vertically arranged drain pipe 3. The drain pipe cover 4 is installed at the top of the drain pipe 3. A filter screen 10 is installed in the middle of the drain pipe cover 4. A closed garbage bin 5 is installed next to the drain pipe 3. A negative pressure pump 6 is installed at the top of the closed garbage bin 5. A filter 7 is installed at the front end of the negative pressure pump 6 and communicates with the closed garbage bin 5. The closed garbage bin 5 is also connected to the fixed suction pipe 8. The front end of the fixed suction pipe 8 is connected to the movable suction pipe 9 via a flexible connecting hose.

[0015] The filter screen 10 is fixedly connected to the side wall of the drain pipe 3 by bolts.
