[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-6 The water conservancy and hydropower gate lifting device shown includes a support frame 1, a gate 2 is provided inside the support frame 1, and a filter mechanism 3 for intercepting debris is provided on both sides of the support frame 1.
[0029] like Figure 4 As shown, the top of the support frame 1 is provided with a lifting mechanism 4 that drives the gate 2 to move up and down.

The worm gear 407 and the worm 408 mesh with each other, and a first motor 409 is fixedly provided at the top of the worm 408.
[0031] Start the first motor 409, which drives the worm gear 408 to rotate. The rotation of the worm gear 408 drives the worm wheel 407 to rotate, which in turn drives the first rotating shaft 402 to rotate. The rotation of the first rotating shaft 402 drives the winding roller 403 to rotate. The rotation of the winding roller 403 winds up the wire rope 404, which in turn drives the gate 2 to move upward, facilitating water release.
[0032] like Figure 3 As shown, the filter mechanism 3 includes two filter plates 301 disposed on both sides of the support frame 1. Multiple placement slots 302 are provided on both sides of the support frame 1. The filter plates 301 are adapted to the placement slots 302. A first threaded hole 303 is provided at each of the four corners of the filter plate 301. A second threaded hole 304 is provided inside each placement slot 302. The first threaded hole 303 and the second threaded hole 304 that are connected to each other are threaded with the same bolt 305.
[0033] In this invention, the filter plate 301 can intercept upstream debris, preventing it from polluting the downstream water flow. Then, the staff can clean the debris on one side of the filter plate 301 to prevent it from clogging. When the filter plate 301 is damaged, the bolt 305 can be turned out from the first threaded hole 303 and the second threaded hole 304, allowing the filter plate 301 to be removed from the support frame 1 for easy replacement and extending the service life of this invention.
[0034] like Figure 5 , 6 As shown, the support frame 1 is provided with an extrusion mechanism 5 for applying lubricating oil to the surface of the wire rope 404. The extrusion mechanism 5 includes a fixed frame 501 inside the support frame 1. The fixed frame 501 is provided with a plurality of fixed pulleys 502 movably connected by bearings. The fixed pulleys 502 are located on both sides of the wire rope 404. Each fixed pulley 502 has a container 503 for holding lubricating oil on its top. The container 503 is fixed to the top of the fixed frame 501 by a bracket.
[0035] like Figure 5 , 6 As shown, a piston plate 504 is provided inside the container 503. A threaded cylinder 505 is movably connected to one side of the container 503 via a bearing. The threaded cylinder 505 passes through the fixing frame 501. A threaded rod 506 is threadedly connected inside the threaded cylinder 505. One end of the threaded rod 506 is fixedly connected to the piston plate 504. A second rotating shaft 507 is movably connected to one side of the container 503 via a bearing. Gears 508 are provided through the outside of both the threaded cylinder 505 and the outside of the second rotating shaft 507. The two gears 508 mesh with each other. A second motor 509 is fixedly provided at one end of the second rotating shaft 507.
[0036] The second motor 509 is started, which drives the second rotating shaft 507 to move. The second rotating shaft 507, under the action of two gears 508, drives the threaded cylinder 505 to rotate. The movement of the threaded cylinder 505 drives the threaded rod 506 to move. The movement of the threaded rod 506 drives the piston plate 504 to move. The piston plate 504 squeezes the lubricating oil inside the container 503, squeezing the lubricating oil onto the surface of the fixed pulley 502. The movement of the wire rope 404 drives the fixed pulley 502 to rotate. As the fixed pulley 502 rotates, it can coat the surface of the wire rope 404 with lubricating oil. Coating with lubricating oil can reduce the friction of the wire rope 404 during the movement, reduce wear, and extend its service life.
[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
