[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electric power generation device. It is a key water conservancy project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires that the use of water energy in a hydropower station be uninterrupted. The gates of a hydropower station are used to control the flow of water.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing hydropower station gate is in use, the further the gate moves downward to close, the greater the driving force required. If the driving force is insufficient, the gate may not be completely closed, leaving a gap at the bottom, causing water leakage, which will affect the power generation of the hydropower station and is inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a hydropower station gate clamping device to solve the problem in the above background technology that when the existing hydropower station gate is in use, the more the gate moves downward to close, the greater the driving force required. When the driving force is insufficient, the gate may not be completely closed, and there may be a gap at the bottom, causing water leakage, which will affect the power generation of the hydropower station and is inconvenient to use.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0052] Working principle: When it is necessary to confirm the closed state of the gate plate 15, a rotational force is applied to the turntable 35 to rotate the turntable 35. The rotation of the turntable 35 drives the positioning rod 34 to rotate. The positioning rod 34 moves downward through the threaded structure. When the positioning rod 34 moves downward, it can pass through the second positioning hole 32 and enter the third positioning hole 33. It means that the movable plate 25 moves to the specified position.
