Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0023] See also Figures 1 to 5The utility model provides a technical solution: an offshore wind turbine support device, including a fixing base 1, a connecting base 2 is provided on the top of the fixing base 1, the fixing base 1 is square, the fixing base 1 is located below the sea level, the upper half of the connecting base 2 is a square platform with a small top and a large bottom, and the lower half of the connecting base 2 is a square platform with a large top and a small bottom.

The threaded holes pass through the fixing seat 1. There are eight threaded holes and they are distributed in a circular array on the first fixing rod 4. The threaded holes are located in the middle of the first fixing rod 4 and the second fixing rod 5. The inner walls of the threaded holes are threadedly connected with fixing bolts 3. The size and number of the fixing bolts 3 are consistent with the threaded holes and correspond one to one with the threaded holes. The top of the connecting seat 2 is fixedly connected to a connecting rod 6. The connecting rod 6 is located in the middle of the connecting seat 2. The connecting rod 6 is an octagonal prism.

There are four support rods 7 and they are distributed in a circular array on the connecting rod 6. The outer end of the support rod 7 is arc-shaped.

[0024] When in use, the existing offshore wind turbine support structure will cause the wind turbine to tilt and shake when the wind is strong, which is not conducive to the conversion of wind energy and has insufficient stability. Therefore, there is an offshore wind turbine support device, which can fix the fixing seat 1 and the connecting seat 2 by fixing bolts 3, and the first fixing rod 4 and the second fixing rod 5 are both located below the mud surface, so that the fixing seat 1 and the connecting seat 2 can be stabilized.

The connecting rod 6 is in the shape of an octagonal prism, and the outer end of the support rod 7 is in the shape of an arc, so that the lateral wind-receiving area of the connecting rod 6 and the support rod 7 can be reduced, thereby reducing wind resistance, reducing the shaking of the bottom of the wind turbine, and improving the stability of the wind turbine support.

[0026] During use, due to the different wind forces at different heights, it is impossible to ensure that the fan can maximize the use of wind energy when it is catching wind. Therefore, there is a support device for an offshore wind turbine. When the fan is catching wind, the telescopic end of the first electric telescopic rod 8 and the telescopic end of the second electric telescopic rod 14 are extended. At this time, the first rotating block 11 and the second rotating block 13 rotate, so that the electric box 9 drives the fan blades 16 to adjust the upper and lower heights, so that the fan can better catch wind.
