[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electric energy generating device. It is a water conservancy hub project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires the uninterrupted use of water energy in the hydropower station. Through the construction of the hydropower station reservoir system, the distribution of water resources in time and space is artificially adjusted and changed to achieve sustainable use of water resources. In order to effectively convert the water energy in the reservoir into electric energy, the hydropower station needs to be realized through a hydro-mechanical system, which is mainly composed of a penstock, a turbine, a generator, and a tailwater pipe.
[0003] The hydroelectric generator is an indispensable part. When the generator needs to be repaired, the turbine needs to be shut down. In order to speed up the stopping of the water wheel inside the turbine, a parking mechanism is used. When shutting down, the brake pads act on the outer wall of the flywheel. This direct action on the flywheel will cause damage to the flywheel and reduce its service life.

[0012] Beneficial Effects
[0013] The utility model provides an intelligent regulating water transmission and power generation device for a hydropower station, which has the following beneficial effects:
[0014] (1) The intelligent regulating water transmission and power generation device of the hydropower station, during the use of the utility model, when the water supply of the turbine is disconnected, in order to stop the rotating flywheel, the position adjustment mechanism is used to move the movable connecting plate forward, the transmission sleeve will follow the movable connecting plate forward, the second friction plate begins to approach the first friction plate, and finally the second friction plate and the first friction plate are in contact with each other.
