[0002] Water conservancy projects are a general term for a series of engineering facilities built by humans to rationally develop, utilize, conserve, and protect water resources and prevent and control floods and droughts. They are not only the lifeblood of agriculture, but also the foundation of urban and industrial development.

Furthermore, the filtration device needs to be disassembled for inspection and maintenance during long-term use. Disassembly is complicated and usually requires bolts and nuts to fix, making it inconvenient for workers to operate and use, thus reducing the practicality of the device. Therefore, a drainage device for water conservancy projects is proposed. Utility Model Content

[0030] The outside of the filter box 2 is fixedly connected to a fixed shell 13, and the inside of the fixed shell 13 is fixedly connected to a first spring 15. The first spring 15 continuously exerts force on the clamping block 14. The end of the first spring 15 is fixedly connected to the clamping block 14, and the clamping block 14 is slidably connected to the fixed shell 13.

[0031] The outer side of the top cover 4 is fixedly connected to a cylindrical shell 16, the outer side of the cylindrical shell 16 is movably connected to a limit rod 19, and a pull rod 18 that limits the movement of the limit rod 19. A limit groove 20 is provided on the side of the cylindrical shell 16, and a fifth limit block 21 is fixedly connected to the outer side of the cylindrical shell 16, and the limit rod 19 is movably connected to the fifth limit block 21;

[0032] The outer side of the cylindrical shell 16 is slidably connected to a hook 17, and the outer side of the hook 17 is movably connected to a pull rod 18, which drives the hook 17 to move;

[0033] A second spring 22 is fixedly connected to the outer side of the hook 17 . The second spring 22 pulls the hook 17 back to the origin. The second spring 22 is fixedly connected to the cylindrical shell 16 .

[0034] In this embodiment, the hook 17 is driven to slide toward the fifth limit block 21 by pulling the pull rod 18. During the sliding process, the end of the hook 17 is stuck under the block 14.
