Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1, please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] A flood control gate for a water conservancy project comprises a buried base 1, a gate frame 2 is fixedly installed on the top of the buried base 1, a driving motor 3 is fixedly installed on the top of the gate frame 2, the output end of the driving motor 3 is fixedly connected to a driving gear 4, the top of the gate frame 2 near its front side is rotatably connected to a rotating rod 5 through a pin shaft seat, the surface of the rotating rod 5 near its rear side is fixedly connected to a driven gear 6, the surface of the driven gear 6 and the surface of the driving gear 4 are meshed and connected, the surface of the rotating rod 5 is fixedly connected to a winding wheel 7, the surface of the winding wheel 7 is transmission-connected with a tough steel rope 8, one end of the tough steel rope 8 is bolted to a lifting gate plate 9, the surface of the lifting gate plate 9 and the surface of the inner wall of the gate frame 2 are sealed and slidably connected, the side of the lifting gate plate 9 near its top is connected to a guide assembly, the bottom of the lifting gate plate 9 is fixedly connected to a sealing plugging plate 10, and a waterproof stretch sleeve 11 is fixedly connected between the top of the lifting gate plate 9 and the top of the inner wall of the gate frame 2.

[0028] Specifically, such as Figure 1-Figure 5 As shown, there are two winding wheels 7, and the two winding wheels 7 are evenly distributed at the front and rear ends of the rotating rod 5. The two winding wheels 7 and two sections of tough steel ropes 8 can smoothly pull the lifting gate plate 9 to move.

[0029] Furthermore, a sealing pad 19 is fixedly connected to the lower surface of the lifting gate plate 9, and the surface of the sealing pad 19 is sealed against the bottom of the inner wall of the gate frame 2. The sealing pad 19 arranged below the lifting gate plate 9 can play a sealing abutment effect below under normal conditions.

[0030] Furthermore, the rear side of the lifting gate plate 9 is fixedly connected with an inclined support plate 20, and the bottom of the inclined support plate 20 is magnetically abutted against the lower surface of the inner wall of the gate frame 2. The addition of the inclined support plate 20 can abut against the gate frame 2 to play a role of magnetic positioning, and can play a role in unloading the impact force of the lifting gate plate 9 caused by external water flow.

[0031] Specifically, such as Figure 1-Figure 5 As shown, the guide assembly includes a guide sleeve 17 and a guide rail 18. The guide sleeve 17 is fixedly connected to the side surface of the lifting gate plate 9 near its top, and the guide rail 18 is fixedly connected to the front side of the gate frame 2. The surface of the guide rail 18 is slidably connected to the inner wall of the guide sleeve 17. Through the arrangement of the guide sleeve 17 and the guide rail 18, the anti-tilt guiding movement effect is ensured during the movement of the lifting gate plate 9.

[0032] Example 2, please refer to Figure 1-Figure 5 The difference between this embodiment and embodiment 1 is that the main body of the buried base 1 is a hollow sewage discharge frame, and a sewage discharge groove cavity 12 is opened on the inner wall of the sewage discharge hollow frame. The top of the inner wall of the sewage discharge groove cavity 12 is rotatably connected with a one-way outward opening plate 13 through a pin shaft with a torsion spring. A circulation groove 14 is opened on the top of the sewage discharge hollow frame, and the inner wall of the circulation groove 14 is communicated with the inner wall of the sewage discharge groove cavity 12. The surface of the sealing plug 10 is sealed and clamped with the inner wall of the circulation groove 14. A reinforcing cone rod 15 is fixedly connected to the bottom of the buried base 1, and a through groove 16 is opened on the inner wall of the reinforcing cone rod 15. When the gate plate 9 is moved upward, the sewage trough cavity 12 blocked by the sealing plate 10 will leak out, so that the discharged water flow will pass through the sewage trough cavity 12 and bring most of the quicksand brought out by the water flow into it. The quicksand can flow through the sewage trough cavity 12 and guide the quicksand to the one-way outward opening plate 13. The one-way outward opening plate 13 will open unidirectionally to the outside under the pressure of heavier accumulated quicksand, and the discharged quicksand will flow downward out of the front side of the gate frame 2, thereby realizing the quicksand interception effect during the process of opening the gate and releasing water.

[0033] The working principle of the utility model is as follows: when in use, the entire gate frame 2 can be buried in the flood control river channel by utilizing the buried base 1, and a reinforcing cone rod 15 is added to extend into the soil, and the soil or concrete can be penetrated in the inner wall of the through groove 16 to enhance the installation stability of the entire flood control gate. When the flood control gate is actually used, the driving motor 3 can be operated to start and drive the active gear 4 to rotate, and the rotation of the active gear 4 can drive the driven gear 6 to rotate, and the rotation of the driven gear 6 can drive the rotating rod 5 to rotate. The winding wheels 7 at the front and rear ends of the rotating rod 5 are both connected with tough steel ropes 8 for transmission. Through two sections of tough steel ropes 8, the lifting gate plate 9 can be pulled smoothly to move, and the guide sleeve Under the setting of 17 and the guide rail 18, the anti-tilt guiding movement effect of the lifting gate plate 9 is guaranteed during the movement. The sealing pad 19 arranged under the lifting gate plate 9 can play a sealing abutment effect at the bottom under normal conditions. After moving up, the lifting gate plate 9 will leak out the sewage trough cavity 12 tightly blocked by the sealing plug 10, so that the discharged water flow will pass through the sewage trough cavity 12 and bring most of the quicksand brought out by the water flow into it. The quicksand can flow through the sewage trough cavity 12 and guide the quicksand to the one-way outward opening plate 13. The one-way outward opening plate 13 will open unidirectionally to the outside under the pressure of heavier accumulated quicksand, and the discharged quicksand will flow downward out of the front side of the gate frame 2, which can achieve the quicksand interception effect during the process of opening the gate to release water, and reduce the occupied range of the driving gate lifting structure.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
