DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-11 In order to solve the problems that traditional wind power equipment is unstable, cannot avoid seabed organisms and stones, cannot adapt to the inclination angle of the ground, and cannot resist the attachment of marine organisms, the wind power equipment is more stable, can avoid seabed organisms and stones, can adapt to the inclination angle of the ground, and resist the attachment of marine organisms, the present invention provides a technical solution: a pile foundation, including a fixed pile 101, a rotating platform 102, a bearing platform 103, and also includes a connecting component. The lower end of the fixed pile 101 is fixed in the seabed ground, and the upper end thereof is rotatably connected to the rotating platform 102. The upper end of the rotating platform 102 is provided with a bearing platform 103. The rotating platform 102 and the bearing platform 103 are connected by a connecting component. A supporting component is provided on the rotating platform 102. The supporting component is used to support the pile foundation. A ground-attaching component is provided at the lower end of the supporting component. The ground-attaching component can fit the angle of the ground. The rotating platform 102 and the bearing platform 103 are both provided with a transmission component. The transmission component is used to control the pile foundation to complete different functions. In the present application, the ultrasonic device 104, the damper 105, the rotating table motor 203, the cam motor 206, the support table motor 209, the cam screw motor 404 and the support table screw motor 408 are all of existing models.

[0027] During installation, first fix the fixed pile 101 to the seabed ground, then control the support assembly to approach the seabed ground, and then determine whether there are marine organisms, stones and other foreign objects near the support point. If there are foreign objects, the support assembly and the rotating table 102 are moved by cooperating with the transmission assembly and the sleeve assembly to make sure that there are no marine organisms, stones and other foreign objects near the support point. Then control the support assembly to descend, and the support assembly drives the fitting assembly to descend until it touches the ground. When the fitting group at the lower end of the support assembly touches the ground, since the seabed ground is not flat but rugged and has an angle, the fitting assembly begins to automatically adapt to the inclination angle of the ground after it touches the ground. Then the support assembly continues to descend, and the support assembly drives the fitting assembly to complete the support. During use, when the direction of the wind power equipment needs to be changed, the transmission assembly is used to control the rotation of the support platform 103, and the support platform 103 drives the wind power equipment to rotate so that the wind power equipment faces the direction of the wind. Then the sleeve assembly is used to fix the support platform 103.

[0028] In order to solve the problem that the traditional pile foundation has only one pile for fixing and cannot avoid seabed organisms and rocks, causing damage to seabed organisms and unstable support, a connecting component and a supporting component are provided to achieve the effect of supporting the ground with a supporting component and avoiding seabed organisms and rocks at the same time.

[0029] During installation, the cam 301 is controlled to rotate by the transmission component. The shape of the cam 301 is a component with a raised profile. When the cam 301 rotates, the cam 301 drives the connecting rod 302 to slide in the connecting rod slide groove 303, and the connecting rod 302 begins to move in the connecting rod limiting hole 304. The connecting rod 302 drives the supporting rod 305 to move, and the distance from the supporting rod 305 to the fixed pile 101 is adjusted. Then, the sleeve assembly is used to fix the cam 301 and the rotating table 102, and then the rotating table 102 is controlled to rotate by the transmission component. The rotating table 102 drives the rotating drum 401 to rotate, and the rotating drum 401 drives the tightening The fixing sleeve 412 rotates, and the tightening sleeve 412 drives the cam 301 to rotate. At the same time, the connecting rod limiting hole 304 on the rotating table 102 drives the connecting rod 302 to rotate, and the connecting rod 302 drives the supporting rod 305 to rotate, and the position of the supporting rod 305 around the fixed pile 101 is adjusted. In the process of changing the position of the supporting rod 305, the two processes of rotating the cam 301 and rotating the rotating table 102 can be adjusted separately, as long as there are no foreign objects such as marine life and stones near the supporting point. After the adjustment is completed, the supporting rod 305 extends close to the ground, and the supporting rod 305 drives the fitting component to descend to complete the support.

The lower end of the ball table 502 is fixedly connected to the adaptation plate 503.

[0031] When the support rod 305 is extended, the support rod 305 drives the limiting ring 501 to descend, the limiting ring 501 drives the ball table 502 to descend, and the ball table 502 drives the adaption plate 503 to descend. When the adaption plate 503 contacts the ground, affected by the inclination angle of the ground, the adaption plate 503 begins to tilt and fit the ground. The rotation of the adaption plate 503 drives the ball table 502 to rotate in the limiting ring 501. When the adaption plate 503 is fixed, the ground-attached component becomes stable.

Since the width of the fastening sleeve 412 is greater than the width of the gap between the support 103 and the fixed cylinder 403, when the fastening sleeve 412 enters the support 103, the support 103 and the fixed cylinder 403 are fixed, and the support 103 cannot rotate; when it is necessary to rotate the support 103, the support screw motor 408 is reversed to cancel the fastening sleeve 412, and the support 103 can be rotated ; When it is necessary to fix the cam 301, the cam screw motor 404 is started, the cam screw motor 404 drives the cam screw 405 to rotate, the cam screw 405 rotates to drive the cam screw sleeve 406 to move, the cam screw sleeve 406 moves to drive the cam driving rod 407 to move, the cam driving rod 407 drives the fastening sleeve 412 on the rotating cylinder 401 to move, and the fastening sleeve 412 enters the cam 301. Since the width of the fastening sleeve 412 is greater than the width of the gap between the cam 301 and the fixed cylinder 403, when the fastening sleeve 412 enters the cam 301, the cam 301 and the rotating cylinder 401 are fixed, and the cam 301 cannot rotate; when it is necessary to rotate the cam 301, the cam screw motor 404 is reversed to cancel the matching of the fastening sleeve 412, and the cam 301 can rotate.
