The advantages of the above invention will be described in detail with reference to the embodiments, and specifically, the blades of the water turbine now in operation are 9 meters long and 3 meters wide, and 6 blades. The length, size and number of other blades can be designed according to different water depths and flow velocities. Wherein, shallow water can use 2 to 4 large and short blades, deep water can use 6 to 10 small and long blades. A core wheel is arranged between the opposite surfaces of the 2 blades and used for fixing the blades.

The length of the medium platform is 60 m square pipe and 80 m circular pipe, wherein about 30 m is driven into the ground (according to geological data). The water depth is 30 meters and the water surface is 20 meters. The force of the medium-large water turbine is very large, the diameter of the square pipe can be increased or decreased according to the flow velocity in the design process in sea areas with different flow velocities, the thickness of the square pipe steel can be increased or decreased, and the size and the thickness of the round pipe behind the square pipe can be increased or decreased.

The diameter of the water turbine is 20 meters, the distance from the highest position of the blades of the water turbine to the water surface is about 10 meters, and the normal power generation of the water turbine is not influenced by sea waves in the case of typhoons. In addition, the platform frame 20 meters above the water surface does not influence the electricity generation of the electric ball due to the sea waves when typhoon exists, and plays a role in lifting the water turbine support. Two rows of stairs are built on two sides above the water surface of the power generation platform, so that workers can conveniently go up and down.
Two small platforms are built on two sides of the frame which is about 2 meters away from the water surface, wherein one side is provided with an installation transformer
The speed case and the hydraulic pump are used, and the opposite platform is used as a working platform. One of 2 small platforms is used for fixing and dismounting the blades of the water turbine when the platform is 10 meters away from the water surface, the other platform is used for installing a crane for hoisting the water turbine,
after the electricity is generated, the electricity can be transmitted to land through the submarine cable and then is supplied by networking through the transformation and the high-voltage wire. The medium-sized frame platform can be used for holding 100 kilowatt/hour to 500 kilowatt/hour water turbines. The power generation platform can be arranged in a row and in a line in the sea area except the navigation channel like a land wind power generation field, and power is transmitted through submarine cables. Years of experimentation have shown that tidal power generation is now in operation.
