[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a filtration device for water conservancy and hydropower engineering with a graded filtration function. Background Technology

[0002] Filtration devices for water conservancy and hydropower projects with graded filtration function intercept impurities such as silt and suspended solids in water in layers according to particle size through multi-stage filtration units. They can achieve gradient purification from pretreatment to fine filtration. They are often equipped with backwashing or self-cleaning systems to ensure efficient filtration under high flow rates, reduce equipment blockage, and improve the operational stability of water conservancy and hydropower systems.

[0003] Most filtration devices have several drawbacks in use, such as the need for tools to fix the filter screen, the potential for bolts to rust and strip after prolonged use, making the filter screen difficult to disassemble, and the overall device becoming clogged and reducing filtration efficiency. Therefore, we propose a filtration device with a staged filtration function for water conservancy and hydropower projects. Utility Model Content

[0009] Preferably, the driving component includes:

[0010] A worm gear is rotatably installed in a limiting groove. Two worm wheels are meshed at the bottom of the worm gear. Two first bevel gears are fixedly installed at one end of each of the two worm wheels. Second bevel gears are meshed at the bottom of each of the four first bevel gears. Threaded rods are fixedly installed at the bottom of each of the four second bevel gears. Several limiting strips pass through the lower ends of the four threaded rods, and the four threaded rods are threadedly connected to the several limiting strips.

[0011] Preferably, the two worm gears, the two worm wheels, the four first bevel gears, the four second bevel gears, and the four threaded rods are all rotatably connected to the limiting groove.

[0012] Preferably, the filtration precision of the plurality of filter screens increases sequentially from top to bottom.

[0014] Preferably, a feed pipe is fixedly installed on the top of the housing.

[0015] Preferably, a handle is fixedly installed on one side of each of the aforementioned fixed frames.

[0016] The beneficial effects of this utility model are:

Filter screens 4 are fixedly installed in each of the several fixed frames 3. Limiting strips 5 are slidably installed in the limiting groove 2 and at the top of the several fixed frames 3. The bottom of the several limiting strips 5 extends into the several fixed frames 3 respectively, and the several limiting strips 5 are inserted and cooperated with the several fixed frames 3 respectively.

[0026] A drive assembly is located inside the housing 1 and is used to drive several limit bars 5 to slide.

[0027] Water enters the housing 1 and is then filtered in stages by several filter screens 4. When it is necessary to replace several filter screens 4, several limit bars 5 slide upward and disengage from several fixed frames 3 through the set drive component, so that several filter screens 4 can be removed. Then, by the above reverse operation, the position of several limit bars 5 can be fixed, which makes it convenient to clean and replace several limit bars 5. The operation is simple and convenient.

[0028] In this embodiment, the driving component includes:

[0029] The worm 6 is rotatably installed in the limiting groove 2. Two worm wheels 7 are meshed at the bottom of the worm 6. Two first bevel gears 8 are fixedly installed at one end of each of the two worm wheels 7. Second bevel gears 9 are meshed at the bottom of each of the four first bevel gears 8. Threaded rods 10 are fixedly installed at the bottom of each of the four second bevel gears 9. Several limiting strips 5 pass through the lower ends of the four threaded rods 10 respectively, and the four threaded rods 10 are threadedly connected to the several limiting strips 5 respectively.

[0030] Water enters the housing 1 and is then filtered in stages by several filter screens 4. When it is necessary to replace the filter screens 4, firstly, the worm gear 6 is rotated. The worm gear 6 drives the two worm wheels 7 that mesh with it to rotate. The two worm wheels 7 drive the four first bevel gears 8 to rotate. The four first bevel gears 8 drive the four second bevel gears 9 that mesh with them to rotate. The four second bevel gears 9 drive the several threaded rods 10 to rotate. Under the action of the threads, the several limiting strips 5 slide upward and disengage from the several fixed frames 3, allowing the filter screens 4 to be removed. The position of the limiting strips 5 can be fixed by the above reverse operation, which makes it easier to clean and smooth the limiting strips 5. The operation is simple and convenient.

[0031] In this embodiment, the two worm gears 6, the two worm wheels 7, the four first bevel gears 8, the four second bevel gears 9, and the four threaded rods 10 are all rotatably connected to the limiting groove 2;

[0032] Specifically, it ensures that the two worm gears 6, the two worm wheels 7, the four first bevel gears 8, the four second bevel gears 9, and the four threaded rods 10 can all rotate within the limiting groove 2.
