Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This utility model provides a technical solution:

[0020] Example

[0021] Regarding the aforementioned problems: the water-stopping effect of existing weir gates is easily affected by debris at the bottom, especially silt, sand, and gravel. During the rotation of the weir gate, these materials are easily drawn into the seal, leading to seal damage, failure, and leakage.

[0022] The solution is as follows: A sand-proof component for the bottom of a rotating weir includes a device body 1. The device body 1 includes a lower base 2, an upper base 3, a sealing seat 4, a rotating shaft mounting bracket 5, a weir gate panel 6, a top fixing block 7, a hydraulic rod movable mounting seat 8, a driving hydraulic rod 9, and a sand-proof rubber plate 10. The lower base 2 is located below the upper base 3. The sealing seat 4 is installed on the top of the lower base 2. The rotating shaft mounting bracket 5 is installed at the front end of the sealing seat 4. The rear end of the weir gate panel 6 is installed at the front end of the rotating shaft mounting bracket 5 via a rotating shaft. The top fixing block 7 is installed at the bottom of the upper base 3. The hydraulic rod movable mounting seat 8 is installed on the outside of the top fixing block 7. The fixed end of the driving hydraulic rod 9 is fixed to the hydraulic rod movable mounting seat 8 via a rotating shaft, and the driving end is connected to the weir gate panel 6. The rear side of the top of the weir gate panel 6 is provided with a sand-proof sealing strip 11 and a bottom skeleton liner 12. The sand-proof sealing strip 11 and the bottom skeleton liner 12 are connected to each other. The inner lining 12 of the frame is distributed horizontally at equal intervals. The sand-proof sealing strip 11 has an L-shaped structure, and the bottom frame inner lining 12 has an arc-shaped structure. The sides of the sand-proof sealing strip 11, the sides of the bottom frame inner lining 12, and the front surface of the sand-proof rubber plate 10 are all provided with through holes 18. The sand-proof sealing strip 11 has a rectangular structure. The front end of the sand-proof sealing strip 11 is fixed between the sand-proof sealing strip 11 and the bottom frame inner lining 12 by bolts. The rear end of the sand-proof sealing strip 11 is provided with a rubber fixing head 13. The surface of the rubber fixing head 13 is provided with a fixing hole 14. A locking bolt 15 is provided in the fixing hole 14. The rubber fixing head 13 is fixed to the top of the sealing seat 4 by the locking bolt 15. When the weir gate plate 6 moves to a horizontal state, this component automatically adheres to the surface of the weir gate plate 6 through the elasticity of the sand-proof rubber plate 10 and gravity, reducing the accumulation of debris on the bottom waterstop strip of the weir gate plate 6 when the water flows through. When large amounts of waste accumulate on this component, the bottom frame liner 12 ensures that the sealing plate itself will not collapse, thus preventing it from contacting the sealing strip of the weir gate panel 6 and being drawn in when the weir gate panel 6 is closed, and also preventing it from affecting the water stop at the bottom of the weir gate panel 6. When the weir gate panel 6 moves to a vertical position, the waste accumulated on the weir gate panel 6 slides off. Due to the protection and isolation provided by the sand-proof rubber plate 10, the waste will not remain on the silt and will slide onto the bottom water stop strip of the weir gate panel 6, thus preventing it from being drawn into the seal and affecting the sealing effect. At the same time, the silt and waste on the surface of the weir gate panel 6 will also slide off, and due to the sand-proof sealing strip 11 at the end of the sand-proof rubber plate 10, it will not enter the protected area through the sealing plate.

[0023] The sand-proof sealing strip 11 includes a sealing base 16 and a sealing block 17. Both the sealing base 16 and the sealing block 17 are smoothly transitioned and integrally formed. The sealing base 16 is located at the bottom of the sealing block 17 and has a triangular shape. The sealing block 17 has a rectangular shape. The sand-proof sealing strip 11 is located at the end of the sand-proof rubber plate 10 and is made of various soft rubbers or silicone. The sand-proof sealing strip 11 is L-shaped, with a thicker long side for fixing to the sand-proof rubber plate 10, and gradually thins to a ">" shape on the short side. The short side contacts the weir gate plate 6, preventing debris from falling onto the lower part of the component when the weir gate plate 6 is closed.

[0024] The top front side of the weir gate panel 6 is provided with a connecting rotating block 19. The connecting rotating block 19 has an n-shaped structure. The surface of the connecting rotating block 19 is provided with a connecting movable port 20. The connecting movable port 20 of the connecting rotating block 19 is for easy insertion of the connecting shaft of the driving end of the driving hydraulic rod 9, so as to movably fix the driving end of the driving hydraulic rod 9 to the connecting rotating block 19.

[0025] Working Principle: During operation, when the weir gate panel 6 moves horizontally, this component automatically adheres to the surface of the weir gate panel 6 through the elasticity of the anti-sand rubber plate 10 and gravity, reducing the accumulation of debris on the bottom waterstop strip of the weir gate panel 6 as water flows through. When large debris accumulates on this component, the bottom frame lining 12 ensures that the sealing plate itself will not collapse, thus preventing it from contacting the sealing waterstop strip of the weir gate panel 6 and being pulled in when the weir gate panel 6 is closed, without affecting the waterstop at the bottom of the weir gate panel 6. When the weir gate panel 6 moves vertically, the debris accumulated on the weir gate panel 6 slides off. Due to the protection and isolation provided by the anti-sand rubber plate 10, the debris will not remain on the silt and will slide onto the bottom waterstop strip of the weir gate panel 6, thus preventing it from being pulled into the seal and affecting the sealing effect. At the same time, the silt and debris on the surface of the weir gate panel 6 will also slide off, and due to the anti-sand sealing strip 11 at the end of the anti-sand rubber plate 10, it will not enter the protected area through the sealing plate.

Hydraulic rod movable mounting seat; 9. Drive hydraulic rod; 10. Sandproof rubber plate; 11. Sandproof sealing strip; 12. Bottom frame liner; 13. Rubber fixing head; 14. Fixing hole; 15. Locking bolt; 16. Sealing base; 17. Sealing block; 18. Through hole; 19. Connecting rotating block; 20. Connecting movable port. All components are general standard parts or known to those skilled in the art. The components, their structure and principles are known to those skilled in the art through technical manuals or conventional experimental methods. The problem this invention solves is that the water-stopping effect of existing weir gates is easily affected by bottom debris, especially silt, sand, and gravel. During the rotation of the weir gate, these materials are easily drawn into the seal, leading to seal damage, failure, and leakage. This invention, through the combination of the above-mentioned components, can effectively prevent large debris such as sand and resin from damaging the seal, thereby protecting the rotating weir gate and increasing its stability and reliability.
