Description

[Technical Field]

[0001] The present invention relates to the technical field of offshore wind power generation, and more particularly to a reinforcement device for the main body of an offshore wind power generation system. [Background technology]

[0002] Offshore wind power generation involves building wind farms on the ocean and utilizing the abundant offshore wind energy resources to generate electricity. It offers the advantages of abundant and renewable energy resources, being eco-friendly and non-polluting, and not occupying land resources. At the same time, it reduces greenhouse gas emissions and is environmentally friendly. Depending on the depth of the ocean in which it is installed, offshore wind farms are divided into intertidal wind farms, offshore wind farms, and deep-sea wind farms. Offshore power generation has high construction costs and faces operational challenges due to the complex marine environment, but its great potential for development has made it the latest frontier in global wind power development.

[0003] The Chinese utility model with registration number CN221722969U discloses a reinforcing device for an offshore wind turbine main body, which includes a guide sleeve attached to the tower of the offshore wind turbine main body and a reinforcing embedded part inserted into the guide sleeve, with the lower end of the reinforcing embedded part extending to the seabed, to reinforce the tower of the offshore wind turbine main body. This application aims to reduce the impact of tidal currents on the stability of the offshore wind turbine main body by increasing the number of guide sleeves connected to the tower of the offshore wind turbine main body and the number of reinforcing embedded parts used, and by performing focused reinforcement treatment on the tower of the offshore wind turbine main body due to unexpected changes in tidal currents after the installation of the offshore wind turbine main body.

[0004] However, the above-mentioned methods only maintain the current state of the offshore wind turbine body, and the offshore wind turbine body may tilt during long-term use due to sedimentation on the undersea continental shelf and the influence of tides, which affects the verticality of the wind turbine structure and significantly threatens the balance and safety of the wind turbine structure, making it impossible to meet the operating requirements of offshore wind turbines. Therefore, we propose a reinforcement device for the offshore wind turbine body. Summary of the Invention [Problem to be solved by the invention]

[0005] In response to the shortcomings of the prior art, the present invention provides a reinforcement device for the offshore wind turbine body to solve the technical problem that the offshore wind turbine body can only maintain its current state, and that the offshore wind turbine body may tilt during long-term use due to sedimentation on the undersea continental shelf and the influence of tides.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The technical solutions in the embodiments of the present invention will be described below clearly and completely with reference to the drawings of the embodiments of the present invention, but it is clear that the described embodiments are only some of the embodiments of the present invention and not all of the embodiments. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any creative ingenuity fall within the scope of protection of the present invention.

[0016] The present invention relates to an offshore wind power generation main body reinforcement device, which comprises a fixed plate 1, a mounting hole 2, a circular hole 3, a rotating pipe 4, a female thread 41, teeth 42, a mounting pipe 5, a male thread 6, a rotating groove 7, a rotating ring 8, a ratchet 81, an arc groove 9, a fixed frame 10, a worm 11, a crank 12, a guide groove 13, a Y-shaped arm 14, a mounting groove 141, a clamp plate 142, a spike portion 143, a guide rod 15, a fixed disc 16, an operating rod 17, an escape groove 18, a ratchet pawl 19, and a spring 20.

[0017] As shown in Fig. 1, mounting holes 2 are provided on the inner outer periphery of the fixed plate 1. As shown in Fig. 2, a circular hole 3 is opened on the right side of the interior of the fixed plate 1. As shown in Fig. 1, a rotating tube 4 is inserted into the circular hole 3, and a mounting tube 5 is inserted into the rotating tube 4, with three to six sets of mounting holes 2. As shown in Fig. 5, a female thread 41 is provided on the inner wall of the rotating tube 4. As shown in Fig. 3, a male thread 6 is provided on the outer wall of the mounting tube 5, and the female thread 41 and the male thread 6 are screwed together.

[0018] As shown in Figures 3 and 4, rotary grooves 7 are opened on the inside and outside of the mounting tube 5, a rotary ring 8 is engaged inside the rotary grooves 7, arc grooves 9 are opened circumferentially inside the rotary ring 8, guide rods 15 are inserted inside the arc grooves 9, the number of arc grooves 9 is 3 to 5 sets, the top ends of the guide rods 15 are flush with the top of the rotary ring 8, and fixed disks 16 are attached coaxially to the top ends of the guide rods 15. As shown in Figure 5, an operating rod 17 is connected vertically to the top surface of the rotary ring 8 between the arc grooves 9.

[0019] As shown in Fig. 4, a guide groove 13 is opened in the circumferential direction on the lower side of the inner cavity of the attachment tube 5, and a Y-shaped arm 14 is inserted into the guide groove 13. As shown in Fig. 3, a ratchet 81 is provided on the outer periphery of the rotating ring 8. As shown in Fig. 4, a relief groove 18 is opened in the circumferential direction on the lower side of the inner wall of the rotating groove 7.

[0020] As shown in FIG. 6, ratchet pawls 19 are inserted into recesses 18, mounting grooves 141 are formed on both sides of the outer end of Y-shaped arm 14, clamp plates 142 are inserted into mounting grooves 141, and spikes 143 are provided on the outer surfaces of clamp plates 142. Springs 20 are connected to the inner ends of ratchet pawls 19, and the inner ends of springs 20 are connected to the inner walls of recesses 18. The provided fixing plate 1, rotating tube 4, mounting tube 5, and Y-shaped arm 14 effectively secure the wind turbine to the undersea continental shelf support. Furthermore, the rotation of rotating tube 4 by worm 11 and teeth 42 realizes relative displacement between mounting tube 5 and rotating tube 4, which is transmitted to the wind turbine to accurately correct the tilt of the wind turbine. This not only improves efficiency but also stability, ensuring normal operation of the wind turbine and strengthening the wind turbine. Furthermore, the combination of the ratchet pawl 19 and ratchet 81 prevents the mounting tube 5 from loosening due to external forces once it has been firmly fastened to the support column, effectively preventing accidental loosening during installation and ensuring the stability and safety of the equipment. The additional clamp plate 142 automatically rotates according to the arc of the support column to fit its surface.

A worm 11 is inserted into the fixed frame 10 via a bearing. Teeth 42 are circumferentially provided on the outside of the rotating tube 4 at a position corresponding to the worm 11, and the worm 11 engages with the teeth 42. A crank 12 is coaxially connected to the front of the fixed frame 10 at a position corresponding to the rotation axis of the worm 11, and an anti-skid sleeve is fitted to the outside of the crank 12. The combination of the worm 11 and crank 12 enables labor-saving driving of the rotating tube 4. The high transmission ratio of the worm 11 significantly reduces the required driving force, and the crank 12 mechanism further enhances the labor-saving effect. Adjustment is easier and more accurate, improving work efficiency.

[0022] This invention effectively secures the wind turbine main body to the undersea continental shelf support using the provided fixing plate 1, rotating tube 4, mounting tube 5, and Y-shaped arm 14. Furthermore, the worm 11 and teeth 42 rotate the rotating tube 4, realizing relative displacement between the mounting tube 5 and the rotating tube 4. This displacement is transmitted to the main body, accurately correcting the tilt of the main body. This not only improves efficiency but also stability, ensuring normal operation of the wind turbine equipment and strengthening the main body. Furthermore, the combination of the provided ratchet pawl 19 and ratchet 81 prevents the mounting tube 5 from loosening due to external forces after being firmly fastened to the support column, effectively preventing accidental loosening during installation and ensuring the stability and safety of the equipment. The additional clamp plate 142 automatically rotates according to the arc of the support column to fit its surface. Furthermore, the fastening of the spikes 143 not only enhances installation stability but also improves installation flexibility and applicability.
