The buffer mechanism 8 includes a buffer shell 81, a buffer rod 82 is slidably connected inside the buffer shell 81, a solenoid valve 83 is fixedly connected to one end inside the buffer shell 81, an air groove 84 is opened inside the buffer shell 81, a spring telescopic rod 85 is fixedly connected inside the buffer shell 81, a pressure sensor 86 is fixedly connected to one side of the spring telescopic rod 85, a second spring 88 is fixedly connected to one end inside the buffer shell 81, one side of the second spring 88 is fixedly connected to one end of the solenoid valve 83, a first spring 87 is fixedly connected to one side of the buffer rod 82, a sealing ring 89 is fixedly connected to the outside of the buffer rod 82, one end outside the buffer shell 81 is rotatably connected to the inside of the upper end of the frame 1, and one end outside the buffer rod 82 is rotatably connected to the lower end of the gravity rod 6.
[0028] As a further implementation of this solution, the number of the frames 1 is four, the frames 1 are fixedly connected by rod bodies, the number of the frames 1 corresponds to the number of the cylinders 2 one by one. A slotted rectangular plate is installed inside the upper end of the frame 1, a through hole in the shape of a cylinder is opened inside the rectangular plate of the frame 1, and a limit ear seat is installed inside the rectangular plate of the frame 1, so that the wind power stator body 7 floats on the sea surface, and at the same time, a stable supporting effect is exerted on the wind power stator body 7 and the gravity rod 6;
[0029] As a further implementation of this solution, the number of the support rods 3 is four to eight, the shape of the limit column cylinder 4 is a slotted cylinder, and a spherical groove is opened inside the limit column cylinder 4. Under the action of the earth's attraction on the lower gravity rod 6, the stability of the wind power stator body 7 can be improved;
[0030] As a further implementation of this solution, the shape of the internal ball 5 is a slotted sphere, the shape of the gravity rod 6 is a cylinder, the upper end of the gravity rod 6 protrudes above the internal ball 5, the lower end of the gravity rod 6 is between the frames 1, and a limit ear seat is installed on the outside of the lower end of the gravity rod 6, which is convenient for driving the buffer mechanism 8 to rotate when the gravity rod 6 shakes, without affecting the shaking of the gravity rod 6;
[0031] As a further implementation scheme of the present scheme, the buffer shell 81 is shaped like a slotted cylinder, and the number of buffer shells 81 is eight. The number of buffer shells 81 corresponds one to one with the number of buffer rods 82. The buffer rods 82 are shaped like cylinders at both ends. Limiting shaft rods are installed on the outside of the buffer shell 81 and the buffer rod 82. One side of the first spring 87 is fixedly connected to the inner side of the air groove 84 opened in the buffer shell 81. The outer side of the sealing ring 89 is fitted with the inner side of the air groove 84 opened in the buffer shell 81. The spring telescopic rod 85 is inside the first spring 87. The pressure sensor 86 is electrically connected to the solenoid valve 83, which can greatly block the shaking of the gravity rod 6 and provide buffering at the same time, thereby improving the stability of the gravity rod 6, further improving the stability of the wind turbine stator body 7, and realizing the function of protecting the stability and safety of the wind turbine stator body 7.
[0032] Workflow: When the device is powered on by an external power supply during use to improve the stability of the wind power stator body 7, the cylinder body 2 drives the frame 1 to float on the sea surface under the buoyancy of seawater. The support rod 3 plays a role in supporting the limit column cylinder 4. When the wind power stator body 7 is shaken by an external force, it drives the gravity rod 6 fixedly connected to the bottom to shake. The gravity rod 6 drives the built-in ball 5 fixedly connected to the outside to shake. At this time, the built-in ball 5 rotates inside the limit column cylinder 4. The shape of the built-in ball 5 is spherical, and a groove is provided on the inner side of the limit column cylinder 4 to facilitate the multi-directional movement of the built-in ball 5. Since the gravity rod 6 at the lower end of the built-in ball 5 is longer than the gravity rod 6 at the upper end of the built-in ball 5, and the gravity rod 6 at the lower end of the built-in ball 5 is heavier than the gravity rod 6 at the upper end of the built-in ball 5 and the weight of the wind power stator body 7, under the action of the earth's attraction on the gravity rod 6 at the lower end, the stability of the wind power stator body 7 can be improved. At the same time, when the gravity rod 6 shakes, it squeezes part of the buffer rod 82 and stretches part of the buffer rod 82. The buffer rod 82 is rotatably connected to the gravity rod 6, and the buffer rod 82 slides inside the buffer housing 81. One end of the buffer rod 82 compresses the first spring 87 and stretches the second spring 88, or stretches the first spring 87 and compresses the second spring 88. The second spring 88 and the first spring 87 play a role in buffering the shaking amplitude of the gravity rod 6. When one end of the buffer rod 82 contacts the pressure sensor 86, the pressure sensor 86 squeezes the spring telescopic rod 85, and the spring telescopic rod 85 extends. The spring telescopic rod 85 does not prevent the normal movement of the buffer rod 82. At this time, it is proved that the shaking amplitude of the gravity rod 6 and the wind power stator body 7 is relatively large, and the stability of the wind power stator body 7 is in danger. At this time, the solenoid valve 83 is closed. At the same time, under the sealing action of the sealing ring 89 between the buffer rod 82 and the buffer housing 81, the air groove 84 between the buffer rod 82 and the solenoid valve 83 is in a closed state at this time. At this time, the shaking of the gravity rod 6 can be blocked greatly and buffered at the same time, improving the stability performance of the gravity rod 6 and further improving the stability of the wind power stator body 7, realizing the function of protecting the stable and safe operation of the wind power stator body 7.
