In the invention, the plurality of limiting blocks 28 are arranged in the bottom plate 1, when the bottom plate 1 is in a balanced state, the limiting blocks 28 extend into the clamping grooves 29, so that the vertical state of the upright column 3 and the bottom plate 1 is maintained, and the upright column 3 is prevented from inclining.

In the invention, a plurality of first pulleys 24 are annularly and equidistantly arranged in the arc-shaped clamping block 21 by taking the floating barrel 13 as a circle center, the floating barrel 13 is internally provided with a pulley groove 25, the first pulleys 24 extend into the pulley groove 25 and are in rolling contact with the pulley groove 25, and the floating barrel 13 can rotate under the action of water flow through the first pulleys 24 and the pulley groove 25.

In the invention, the first pulley 24 is arranged in the arc-shaped clamping block 21, when water flows through the buoy 13, the buoy 13 can rotate through the second connecting plate 36, and the stability of the bottom plate 1 can be maintained in the rotating process of the buoy 13.

In the invention, a plurality of second connecting plates 36 are annularly and equidistantly arranged on the outer wall of the buoy 13, and when water current flows, the buoy 13 can rotate through the second connecting plates 36.

According to the invention, the circular groove 30 is arranged at the bottom of the bottom plate 1, the inner walls of the sides, far away from each other, of the circular grooves 30 are fixedly connected with the bases 31, the two sides of each of the two bases 31 are rotatably connected with the arc-shaped clamping blocks 32, the bottoms of the two arc-shaped clamping blocks 32 are fixedly connected with the two symmetrical fixing seats 33, the same screw 34 penetrates through the inner threads of the two adjacent fixing seats 33, the rolling ball 2 can be blocked through the arc-shaped clamping blocks 32, and the rolling ball 2 can be conveniently replaced after being worn.

The advantages of the second embodiment over the first embodiment are: bottom plate 1's bottom is equipped with circular slot 30, the equal fixedly connected with base 31 of one side inner wall that circular slot 30 kept away from each other, and the both sides of two bases 31 are all rotated and are connected with arc fixture block 32, and two symmetrical fixing bases 33 of the equal fixedly connected with in bottom of two arc fixture blocks 32, and two adjacent fixing base 33 internal threads run through have same screw rod 34, can block rolling ball 2 through arc fixture block 32, make things convenient for rolling ball 2 to appear changing after wearing and tearing.

A method of straightening an offshore wind turbine to facilitate balance self-straightening, comprising the steps of:

s1, the bottom plate 1 is placed at a designated position, the screw 34 is unscrewed, the connection of the two arc-shaped fixture blocks 32 is released, the arc-shaped fixture blocks 32 are rotated, the rolling ball 2 and the upright post 3 can be installed in the bottom plate 1, and the limiting block 28 slides into the clamping groove 29 under the elastic force of the second spring 27 to position the rolling ball 2;

s2, rotating the rotating rod 18 to drive the second bevel gear 19 to rotate, wherein the second bevel gear 19 is meshed with the first bevel gear 17 to drive the bidirectional screw 16 to rotate, and the sliding plate 20 starts to move towards two sides due to the threaded connection between the bidirectional screw 16 and the sliding plate 20, so that the clamping of the buoy 13 is released, and the buoy 13 is convenient to replace;

s3, when waves come, water flows pass through the buoy 13, the buoy 13 can rotate due to the water flows through the second connecting plate 36, impact of the water flows can be counteracted to a certain degree in the rotating process of the buoy 13, and stability of the bottom plate 1 can be kept;

s4, when waves come, water flows through the bearing conical block 5, the bearing conical block 5 can be rotated by the water flows through the first connecting plate 35, the bearing conical block 5 can be prevented from being impacted by the water flows to move greatly, and the upright post 3 is prevented from being inclined;

s5, when the bottom plate 1 inclines, the upright post 3 can be in a vertical state through the bearing conical block 5, and the rolling ball 2 rotates in the bottom plate 1, so that the upright post 3 is prevented from inclining along with the bottom plate 1.

Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
