[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a protective grille for water conservancy projects.

[0026] The utility model provides Figure 1-3 A protective grille for a water conservancy project is shown, comprising a grille mesh plate 1 and support columns 2 fixedly arranged at the bottom of the grille mesh plate 1, the bottoms of the plurality of support columns 2 are all arranged in a cone shape, two symmetrically arranged vertical plates 3 are fixedly embedded inside the grille mesh plate 1, both ends of the two vertical plates 3 are provided with grooves, a cross bar 4 is rotatably arranged in the groove, a sprocket 5 is fixedly sleeved on the rod wall of the cross bar 4, a chain 6 is longitudinally transmitted between the two sprockets 5, and a plurality of supporting plates 8 are fixedly arranged on the outer walls of the chain links of the two chains 6 through a plurality of connecting rods 7.

[0027] When the protective grille is in use, the grille mesh plate 1 is inserted next to the water conservancy project through the support column 2. At this time, the space below the grille mesh plate 1 can be used for the support plate 8 to pass through. During the use of the grille mesh plate 1, the water flow on the surface of the water conservancy project can drive multiple sprockets 5 to rotate, so that the multiple sprockets 5 drive the chain 6 to transmit, so that under the support of multiple connecting rods 7, multiple support plates 8 can rise with the chain 6. During the transmission process of the support plate 8, the debris pushed by the water to the side of the protective grille can be supported by the support plate 8 and away from the water surface and transported to the other side of the protective grille, which is convenient for centralized collection of debris and ensures that the surface of the water in the water conservancy project is clean.

[0028] In order to be able to drive the sprocket 5 to rotate by the push of water, Figure 2-3As shown, two symmetrically arranged sliding bars 9 are slidably penetrated at the inner lower end of the grille mesh plate 1, and a floating plate 10 is fixedly arranged at the ends of the two sliding bars 9. The floating plate 10 is a foam floating plate, and a rod wall sleeve of the sliding bar 9 is provided with a spring 16. The two ends of the spring 16 are respectively fixedly connected to the sliding bar 9 and the grille mesh plate 1, and a one-way driving mechanism is provided between the floating plate 10 and the cross bar 4. The one-way driving mechanism includes a cross plate 11, which is fixedly connected to the back side of the floating plate 10, and a plurality of rotation grooves arranged at intervals are opened on the top, a fixed rod 12 is fixedly provided in the rotation groove, and a rod wall sleeve of the fixed rod 12 is provided with a ratchet 13 for rotation, and the ratchet 13 is arranged on a side close to the floating plate 10 in cooperation with the inside of the rotation groove, and a plurality of ratchet teeth 13 are cooperated with a ratchet 14, and the ratchet 14 is fixedly sleeved on the outer side of the cross bar 4, and a torsion spring 15 is provided on the rod wall sleeve of the fixed rod 12, and the two ends of the torsion spring 15 are respectively fixedly connected to the fixed rod 12 and the ratchet 13.

[0029] When water flows on the surface of the water conservancy project, the floating plate 10 is pushed and drives the sliding rod 9 to move horizontally, and stretches the spring 16. When the floating plate 10 moves, the floating plate 10 drives the cross plate 11 to slide. At this time, multiple ratchets 13 push the ratchet 14 under the limit of the inner wall of the rotating groove, so that the ratchet 14 can drive the cross bar 4 and the sprocket 5 to rotate, so that the support plate 8 can be stably transmitted. After the floating plate 10 is away from the grid, with the elastic force of the spring 16 and the torsion of the torsion spring 15, the floating plate 10 can rebound to its original position. During the process, the ratchet 13 does not push the ratchet 14, so that during the continuous reciprocating movement of the floating plate 10, the cross bar 4 only rotates unidirectionally, which is convenient for multiple support plates 8 to rotate stably in one direction to transport surface debris, reducing the provision of external energy.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that 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.
