[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1 This embodiment provides an energy storage support structure for offshore wind turbines, referring to... Figure 1 and Figure 2 The offshore wind turbine energy storage support structure includes an energy storage support component 1, a connecting component 2, an aquaculture component 3, and a first connecting rope 4. The energy storage support component 1 is used to be set at a corresponding position in the ocean, and includes a tower 11 and a support platform 12 connected to the tower 11. The support platform 12 is equipped with an energy storage container 13. The connecting component 2 is sleeved and connected to the outside of the tower 11, and is used to float on the sea surface and move relative to the tower 11. The aquaculture component 3 is connected to the connecting component 2 through the first connecting rope 4, and is used to cultivate fish and shrimp.

[0031] The embodiments of the present invention at least alleviate the technical problem in the prior art where the support platform only has the function of placing standard container energy storage devices, while the use of components such as towers is less common, resulting in the support foundation structure having a single function.

[0032] In this embodiment of the invention, vertically distributed towers 11 are installed at corresponding positions in the sea, and support platforms 12 are set at corresponding heights of the towers 11, so that corresponding energy storage containers 13 can be set on the support platforms 12; while a connecting component 2 is sleeved on the outside of the towers 11, the connecting component 2 is located below the support platform, and the connecting component 2 is connected to the aquaculture component 3 through the first connecting rope 4. The aquaculture component 3 is set in the sea, so that the aquaculture equipment can be supported and connected through the energy storage support component 1 while aquaculture is carried out, thereby realizing aquaculture around the towers 11.

[0033] Compared with the prior art, the offshore wind turbine energy storage support structure provided in this embodiment of the invention enables multiple uses at the fixed pile foundation in the ocean by aquaculture around the tower 11. In addition, multiple energy storage containers 13 are set on the top of the tower 11 through the support platform 12 to achieve multiple uses such as marine aquaculture while meeting conventional use requirements.

[0034] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The connecting component 2 includes a float 21, a sleeve 22, and a second connecting ear 24. The sleeve 22 is slidably fitted on the outside of the tower 11. The float 21 is connected to the sleeve 22 and is used to float on the sea surface. One end of the second connecting ear 24 is connected to the sleeve 22, and the other end of the second connecting ear 24 is connected to the aquaculture component 3 through the first connecting rope 4.

[0035] Specifically: The sleeve 22 is fitted onto the outside of the tower 11, with a gap between the sleeve 22 and the tower 11. A float 21, which is annular in shape and made of materials such as foam, is provided on the outside of the sleeve 22. The sleeve 22 has at least one second connecting lug 24, with one end of the second connecting lug 24 extending out of the float 21 and having a connecting hole at the end. The second connecting lug 24 is connected to the first connecting rope 4 through this connecting hole, thereby positioning the aquaculture component 3 relative to the tower 11. It should be noted that the buoyancy provided by the float 21 is greater than the weight of the sleeve 22, allowing the sleeve 22 to float on the water surface.

[0036] Furthermore, referring to Figure 2 The connecting assembly 2 also includes a plurality of rollers 23, which are distributed circumferentially along the inner wall of the sleeve 22, and all of the rollers 23 move along the extension direction of the tower 11.

[0037] Specifically: multiple rollers 23 are distributed circumferentially along the inner wall of the sleeve 22, and the multiple rollers 23 are connected to the sleeve 22 by bolts and nuts or by welding. Each sleeve 22 is distributed in the vertical direction so that the sleeve 22 can rise and fall with the change of sea level. And due to the action of the rollers 23, the sleeve 22 is prevented from rubbing against the tower 11.

[0038] In an optional implementation of this embodiment, refer to Figure 1 The energy storage support assembly 1 also includes multiple diagonal bracing ribs 15, which are distributed at intervals along the circumference of the tower 11, and each diagonal bracing rib 15 is supported and connected to the bottom of the support platform 12.

[0039] Specifically: the diagonal bracing rib 15 is used to connect the outer wall of the tower 11 to the bottom of the support platform 12, so as to provide stable support for the support platform 12 and the multiple energy storage containers 13 set on the support platform 12.

[0040] Furthermore, referring to Figure 1The corresponding diagonal bracing rib 15 is provided with a first connecting ear 151; the end of the first connecting rope 4 facing away from the second connecting ear 24 passes through the breeding component 3 and is connected to the corresponding first connecting ear 151.

[0041] Specifically, the first connecting lug 151 is connected to one end of the first connecting rope 4, so that the first connecting rope 4 connects to the second connecting lug 24 after passing through the third connecting lug 33. In use, since the length of the first connecting rope 4 is fixed, as the sea level rises, the distance between the third connecting lug 33 and the first connecting lug 151 decreases due to the increased height, while the distance between the third connecting lug 33 and the second connecting lug 24 may increase. This allows the aquaculture component 3 to move away from the support platform 12, preventing collisions.

[0042] In an optional implementation of this embodiment, refer to Figure 1 The energy storage support assembly 1 also includes a ladder 16, which is distributed vertically and is connected to the support platform 12 and the tower 11 respectively.

[0043] Specifically: the ladder 16 is connected to the support platform 12 and the tower 11 respectively. The tower 11 is equipped with a connecting ring so that users can dock the boat and climb from the ladder 16 to the support platform 12.

[0044] In an optional implementation of this embodiment, refer to Figure 1 The energy storage support assembly 1 also includes a fence 14, which is provided along the edge of the upper surface of the support platform 12 and is used to provide protection for the energy storage container 13 and personnel.

[0045] Specifically, a fence 14 is installed along the edge of the upper surface of the support platform 12 to enclose the energy storage container 13, preventing the equipment from falling off the support platform 12. The fence 14 also ensures the personal safety of the staff, preventing them from falling off the support platform 12. In addition, the fence 14 has an opening at the ladder 16 to facilitate staff movement.

[0046] In an optional implementation of this embodiment, refer to Figure 1 The aquaculture component 3 includes a float 31, an aquaculture net 32, and a third connecting lug 33. The float 31 is used to float on the sea surface and is connected to the aquaculture net 32. The aquaculture net 32 ​​is located below the sea surface and is used to raise fish and shrimp. The float 31 is provided with a third connecting lug 33 and is connected to the first connecting rope 4 through the corresponding third connecting lug 33.

[0047] Specifically: the float 31 can be circular or rectangular, and the bottom of the float 31 is provided with a breeding net 32, forming a three-dimensional space inside the breeding net 32 ​​to facilitate the breeding of fish and shrimp inside the breeding net 32; while the third connecting lug 33 provided on the outer wall of the float 31 is slidably connected to the first connecting rope 4.

[0048] Furthermore, referring to Figure 1 The floats 31 are provided in multiple sets, and the third connecting lugs 33 of adjacent floats 31 are connected by the second connecting rope 5.

[0049] Specifically, multiple sets of buoys 31 are provided, and each adjacent buoy 31 is provided with a third connecting lug 33 facing each other. The adjacent third connecting lugs 33 are connected by a second connecting rope 5, so that multiple buoys 31 and aquaculture nets 32 are connected in series. This realizes the need to increase the aquaculture area and the number of aquacultures.

[0050] In an optional implementation of this embodiment, refer to Figure 1 The bottom of the aquaculture net 32 ​​is equipped with multiple counterweights.

[0051] Specifically, by adding counterweights to the bottom of each aquaculture net 32, the bottom edge of the aquaculture net 32 ​​can be stretched open, thereby effectively preventing the bottom of the aquaculture net 32 ​​from folding or knotting.

[0052] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The above embodiments in this specification are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
