DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] Referring to Figure 1 , Figure 2 and Figure 3The application provides a small offshore wind turbine tower for offshore wind power with a stable structure, which comprises a wind turbine tower body 1, a bearing plate 2 fixedly installed at the bottom of the wind turbine tower body 1, a plurality of assembly holes 9 formed in the top of the bearing plate 2 and uniformly distributed, bolts and other connecting locking pieces for fixing and installing the bearing plate 2 and the offshore foundation structure, a wind turbine generator set 3 fixedly installed at the top of the wind turbine tower body 1 and used for stably supporting the wind turbine generator set 3, two fixed sleeves 4 fixedly sleeved on the wind turbine tower body 1, four fixed rings I 5 fixedly installed on the outer walls of the two fixed sleeves 4 and uniformly distributed, eight stable ropes 6 fixedly connected to the eight fixed rings I 5, eight fixed rings II 7 fixedly installed at the top of the bearing plate 2, and the bottom ends of the eight stable ropes 6 fixedly connected to the corresponding fixed rings II 7.

[0024] In the embodiment, eight groups of rope fastening mechanisms 8 are arranged on the bearing plate 2, and the eight groups of rope fastening mechanisms 8 are respectively used for tightening and straightening the corresponding stable ropes 6. The rope fastening mechanism 8 comprises a mounting box 81, an I-shaped winding wheel 82 and a traction rope 83. The mounting box 81 is fixedly installed at the top of the bearing plate 2, the I-shaped winding wheel 82 is arranged in the mounting box 81, and the traction rope 83 is wound on the I-shaped winding wheel 82. One end of the traction rope 83 extends out of the mounting box 81 and is fixedly connected to the stable rope 6. The rope fastening mechanism 8 further comprises an axle seat 84, a rotating shaft 85 and a motor 86. The axle seat 84 and the motor 86 are respectively fixedly installed on the inner walls on the two sides of the mounting box 81. One end of the rotating shaft 85 is rotatably connected to the axle seat 84, and the other end of the rotating shaft 85 is fixedly connected to the output shaft end of the motor 86. The I-shaped winding wheel 82 is fixedly sleeved on the rotating shaft 85. The rotating shaft 85 and the I-shaped winding wheel 82 are driven to rotate by the motor 86, so as to wind the traction rope 83 and further tighten and straighten the stable rope 6. This design is simple to operate, can quickly adjust the tightness of the stable rope 6, adapts to different working environments and wind conditions, and ensures that the stability of the wind turbine tower body 1 is always in the best state.

[0025] In the embodiment, the top of the mounting box 81 is provided with an avoiding hole, and one end of the traction rope 83 penetrates through the avoiding hole, so as to facilitate the traction rope 83 to enter and exit the mounting box 81.

[0026] In the embodiment, the rope fastening mechanism 8 further comprises an electric hydraulic cylinder 87 and an arc-shaped stop plate 88. The electric hydraulic cylinder 87 is fixedly installed on the inner wall of the bottom of the installation box 81, and the arc-shaped stop plate 88 is fixedly installed on the output shaft end of the electric hydraulic cylinder 87. The arc-shaped stop plate 88 is in abutment with the bottom of the I-shaped winding wheel 82, and the upper surface of the arc-shaped stop plate 88 and the outer surface of the I-shaped winding wheel 82 are both configured as frosted surfaces. The electric hydraulic cylinder 87 and the arc-shaped stop plate 88 are designed such that, after the I-shaped winding wheel 82 tightens the traction rope 83, the electric hydraulic cylinder 87 pushes the arc-shaped stop plate 88 upward to abut against the bottom of the I-shaped winding wheel 82. The frosted surfaces of the two increase the friction, preventing the I-shaped winding wheel 82 from being reversed to cause the traction rope 83 to be loosened, and further improving the reliability of fastening the stable rope 6.

[0027] In the embodiment, the top of the installation box 81 is provided with two brackets fixedly installed thereon, and two fixed pulleys 89 are rotatably installed on the two brackets. The two fixed pulleys 89 are symmetrically distributed on the two sides of the traction rope 83 and are in contact with the traction rope 83. During the winding and unwinding of the traction rope 83, the fixed pulleys 89 can change the direction of force, reduce the friction between the traction rope 83 and the installation box 81, reduce the wear degree of the traction rope 83, prolong the service life of the traction rope 83, and reduce the maintenance cost.

[0028] In the embodiment, the outer surface of the installation box 81 is sprayed with rust-proof paint, which can effectively prevent the corrosion of corrosive media such as seawater and sea wind on the installation box 81, prolong the service life of the equipment, and improve the reliability and stability of the equipment in harsh marine environments.

[0029] In the embodiment, it should be noted that the motor 86 is a reversible motor. The circuit connection mode and control mode of the motor 86 and the electric hydraulic cylinder 87 are mature technologies in the art, which have been fully disclosed and described, and thus will not be described herein.

[0030] Through the above structure, the small offshore wind turbine tower with a stable structure for offshore wind power provided in the application is used. The bolt connection locking piece is used to firmly install and fix the bearing plate 2 on the offshore foundation structure (for example, a support frame fixed on the sea). The bearing plate 2 provides basic support for the entire wind turbine tower body 1. The gravity of the wind turbine tower body 1 and the top wind turbine generator set 3 is evenly distributed to the underlying foundation structure. Then one end of each of the eight stable ropes 6 is connected and fixed to the corresponding fixed ring one 5, and the other end of each of the eight stable ropes 6 is connected and fixed to the corresponding fixed ring two 7. In the marine environment, when the wind and sea waves impact the wind turbine tower body 1, the stable ropes 6 can provide multiple directional pulling forces for the wind turbine tower body 1 through the pulling action, balance the external forces, reduce the shaking and tilting of the wind turbine tower body 1, and maintain its stability.

[0031] After long-term use, when the stable rope 6 is loosened and deformed and is not in a taut state, first control the electric hydraulic cylinder 87 to retract and reset, that is, the arc-shaped abutting plate 88 is lowered and does not contact the I-shaped winding wheel 82, then control the motor 86 to operate, the output shaft drives the rotating shaft 85 and the I-shaped winding wheel 82 to rotate, when the I-shaped winding wheel 82 rotates, the traction rope 83 connected to one end of the stable rope 6 is gradually wound, thereby driving the stable rope 6, and the tightness of the stable rope 6 is adjusted, when the stable rope 6 is adjusted to a taut state, the operation of the motor 86 is stopped, then the electric hydraulic cylinder 87 is controlled to extend and operate, the output shaft of the electric hydraulic cylinder 87 pushes the arc-shaped abutting plate 88 upward, the arc-shaped abutting plate 88 tightly abuts the bottom of the I-shaped winding wheel 82, which effectively prevents the I-shaped winding wheel 82 from being reversed under the influence of external vibration and other factors, avoids the loosening of the traction rope 83, ensures that the stable rope 6 is always in a taut state, and the stability of the fan tower body 1 can be maintained.
