[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the present invention, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0050] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present invention specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this document.

[0051] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings connoted by each term.

[0052] like Figures 1 to 4 As shown, the present invention discloses an offshore single-column wind turbine with a ship anti-collision device, which includes: a single-column wind turbine foundation 10 and a ship anti-collision device, wherein the single-column wind turbine foundation 10 is preferably a cylindrical rod-shaped structure. The single-column wind turbine foundation 10 is installed on the seabed, with the base fixed to the seabed and the top connected to the offshore wind turbine tower.

[0053] Here, the single-column wind turbine foundation 10 may adopt a common offshore single-column wind turbine foundation structure, and does not specifically refer to an offshore single-column wind turbine foundation of a certain model and specification.

[0054] The ship anti-collision device is installed on the single-column wind turbine foundation 10 to protect against collisions with ships on the sea surface. The ship anti-collision device may include at least one floating energy absorbing box 20 and at least one anti-collision assembly 30. For example, the ship anti-collision device in this embodiment includes four floating energy absorbing boxes 20 and 48 sets of roller-type anti-collision assemblies 30. The floating energy absorbing box 20 floats on the sea surface.

[0055] Of course, the number and arrangement of the floating energy absorption boxes 20 and the anti-collision gates 30 are only examples. Other numbers and arrangements are also within the protection scope of the present application and do not affect the implementation of the technical solution of the present application, so they will not be elaborated here.

[0056] Each floating energy absorbing box 20 is installed on the outer surface of the single-column wind foundation 10 through a sliding assembly 40, so that the floating energy absorbing box 20 can move up and down along the single-column wind foundation 10. The anti-collision assembly 30 is installed on the outer surface of the floating energy absorbing box 20 to guide the impacting ship to yaw.

[0057] Combination Figure 5 As shown, the sliding assembly 40 includes an inner slide rail 41 and an outer slide rail 42. The inner slide rail 41 is installed on the outer surface of the single-column wind turbine foundation 10 (i.e., the outer side of the cylindrical outer plate of the single-column wind turbine foundation 10), and the outer slide rail 42 is installed on the inner side of the floating energy absorption box 20 (e.g., fixed at the joint of the floating energy absorption box 20). The outer slide rail 42 and the inner slide rail 41 cooperate with each other and are assembled together.

[0058] The slide rail assembly 40 also includes a slide rail limiter 43 and a rubber anti-collision strip 44. The slide rail limiter 43 is installed at both ends of the inner slide rail 41, and the rubber anti-collision strip 44 is installed on the inner side of the slide rail limiter 43 to prevent the outer slide rail 42 and the inner slide rail 41 from colliding with each other.

[0059] The main function of the slide rail assembly 40 in the present application is to limit the freedom of movement of the floating energy absorbing box 20. Under the restriction of the slide rail assembly 40, the floating energy absorbing box 20 can only move vertically along the single-column wind turbine foundation 10 at sea as the water level changes, without generating a large lateral displacement and rotational movement around the axis, thereby avoiding direct collision and friction between the floating energy absorbing box 20 and the single-column wind turbine foundation 10 at sea.

[0060] In this embodiment, the floating energy absorbing box 20 is circumferentially arranged on the outer surface of the single-column wind turbine foundation 10. For example, the ship anti-collision device includes a plurality of floating energy absorbing boxes 20, and the floating energy absorbing boxes 20 may preferably be arc-shaped and sequentially spliced ​​to form a circular ring. Two adjacent floating energy absorbing boxes 20 are tightly connected together by a connector (such as a rivet) to form a ring. Then the floating energy absorbing box 20 is connected to the single-column wind turbine foundation 10 at sea through the slide rail assembly 40, and the floating energy absorbing box 20 can be vertically displaced along the single-column wind turbine foundation 10 at sea.

[0061] Combination Figure 6 As shown, the floating energy absorbing box 20 preferably includes a hollow energy absorbing box body 21, an energy absorbing box cover 22 and a honeycomb energy absorbing baffle 23. The honeycomb energy absorbing baffle 23 is installed in the energy absorbing box body 21, and the energy absorbing box cover 22 is installed on the upper end of the energy absorbing box body 21 to form a closed box structure that can float on the water surface. When the floating energy absorbing box 20 is hit by a ship, the honeycomb energy absorbing baffle 23 can support the energy absorbing box body 21 so that the energy absorbing box body 21 does not undergo significant deformation.

[0062] Based on this structure, the outer slide rails 42 can be installed at both ends of the inner side of the energy absorption box body 21. This arrangement of the slide rails is the most stable, and the energy absorption box body 21 can be stably installed on the outer surface of the single-column wind turbine foundation 10.

[0063] Combination Figure 7 and Figure 8 As shown, each anti-collision assembly 30 includes an anti-collision roller 31, a plurality of roller brackets 32 and a roller bearing 33. The roller bracket 32 ​​is fixed on the outer surface of the floating energy absorption box 20. The roller bearing 33 passes through the anti-collision roller 31, and the two ends of the roller bearing 33 are respectively connected to the roller bracket 32.

[0064] Further preferably, a roller bracket gasket 34 is further provided between the roller bracket 32 ​​and the outer surface of the floating energy absorbing box 20. For example, the roller bracket gasket 34 is respectively connected to the roller bracket 32 ​​and the energy absorbing box body 21 of the floating energy absorbing box 20 to disperse the impact load of the ship.

[0065] The anti-collision roller 31 is preferably made of high elastic rubber material, mounted on the outside of the roller bearing 33, and in close contact with the roller bearing 33. Under the restriction of the roller bracket 32, the roller bearing 33 can rotate with a single degree of freedom around its axis.

[0066] In this embodiment, multiple rows and layers of anti-collision components 30 are arranged on the outer surface of each floating energy absorbing box 20, so that the anti-collision components 30 are evenly spread over the outer surface of the floating energy absorbing box 20 to ensure that the outer surface of the floating energy absorbing box 20 is enclosed and protected from collision.

[0067] When a ship collision occurs, the anti-collision drum 31 rotates to guide the impacting ship to yaw, thereby reducing the impact load on the floating energy absorbing box 20 and the single-column wind turbine foundation 10 at sea.

[0068] In summary, the offshore single-column wind turbine with a ship anti-collision device of the present invention can effectively protect the safety of the offshore single-column wind turbine and reduce the operation and maintenance cost of wind power by arranging a floating ship anti-collision device around the foundation of the offshore single-column wind turbine.

[0069] The ship anti-collision device has high structural utilization rate and good anti-collision performance, is suitable for offshore fixed offshore wind turbines, and can effectively protect the safe operation of the foundation and tower of a single-column wind turbine when it is hit by a ship.
