[0002] At present, almost all offshore wind farms in my country use traditional foundation-fixed wind turbines. However, compared with offshore wind energy resources, my country's deep-sea wind energy resources have greater potential, with reserves of about 1 billion kilowatts, equivalent to twice the offshore resources, and have huge development potential. my country's offshore wind power development will inevitably expand from offshore to deep-sea. However, when the water depth exceeds 50 meters, the cost of traditional fixed foundations increases, so it is an inevitable choice to achieve economical and effective wind energy development in deep waters.

[0003] With the increase in marine development activities, the stability and safety of buoys, as key components of offshore power generation platforms, are particularly important. The marine environment is complex and changeable, including strong winds and waves, tidal changes, etc., which will bring severe challenges to the fixation and operation of the buoys. The buoys in the related technology are annular cylinders wrapped around the frame rods, which are formed by splicing two semicircular buoys. This setting makes it difficult to install the buoys on the frame rods, and the assembled buoys are prone to damage or loose binding, causing the buoys to lose stability, thereby posing a threat to the safety and stability of the entire offshore power generation platform, and even causing accidents.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] Combine the following Figure 1-Figure 5 A buoy 200 according to an embodiment of the present invention is described.

[0028] The buoy 200 of the embodiment of the present invention comprises a floating body 1 and a fastener 2. The floating body 1 is provided with a receiving groove 14. The receiving groove 14 extends along a first direction and passes through the floating body 1. The receiving groove 14 has a first opening facing a second direction, and the second direction is perpendicular to the first direction. The fastener 2 is connected to the floating body 1, and a part of the fastener 2 is located in the receiving groove 14 to block a part of the first opening. The fastener 2 is suitable for preventing the frame rod 3 fitted in the receiving groove 14 from being separated from the receiving groove 14 through the first opening.

[0029] According to the buoy 200 of the embodiment of the present invention, a receiving groove 14 capable of fully matching the frame rod 3 is provided on the buoy 1. After the fastener 2 is connected to the buoy 1, part of the fastener 2 is located in the receiving groove 14 to limit the frame rod 3 in the receiving groove 14, so as to prevent the frame rod 3 from escaping from the receiving groove 14 through the first opening. In other words, the installation of the buoy 200 on the frame rod 3 can be completed by simply sleeve-fitting the buoy 1 on the frame rod 3 through the first opening, and then connecting the fastener 2 to the buoy 1. The structure of the buoy 200 is simple and easy to install. Moreover, by hiding part of the fastener 2 in the receiving groove 14, the connection between the fastener 2 and the buoy 1 is less susceptible to the complex environment at sea, the installation of the buoy 200 on the frame rod 3 is reliable, and the safety and stability of the offshore power generation platform 100 are high.

[0030] It should be noted that the frame rod 3 can extend in the horizontal direction or in the vertical direction. When the frame rod 3 extends in the horizontal direction, the first opening of the accommodating groove 14 is preferably set upward. When the float 200 is installed on the frame rod 3, the part of the fastener 2 located in the accommodating groove 14 is pressed against the frame rod 3.

[0031] In some embodiments, Figure 1 and Figure 2 As shown, the float 1 includes a first side panel 11, a middle panel 12 and a second side panel 13 connected in sequence, the first side panel 11 and the second side panel 13 are arranged at intervals along a third direction, the third direction, the first direction and the second direction are perpendicular to each other, the first side panel 11, the middle panel 12 and the second side panel 13 surround a molded receiving groove 14, and a fastener 2 connects the first side panel 11 and the second side panel 13.

[0032] When the frame rod 3 is located in the accommodating groove 14 and abuts against the inner wall surface of the middle plate 12, the fastener 2 can extend along the width direction of the accommodating groove 14 and be connected to the portion of the first side plate 11 and the second side plate 13 that is located away from the middle plate 12. At this time, the connection between the fastener 2 and each of the first side plate 11 and the second side plate 13 is convenient and reliable, and the connection cost is low.

[0033] Specifically, the first side plate 11 and the second side plate 13 are of the same size, the first side plate 11 and the second side plate 13 are parallel to each other, the middle plate 12 is an arc-shaped plate, and the receiving groove 14 formed around the first side plate 11, the middle plate 12 and the second side plate 13 is a U-shaped groove. In addition, the first side plate 11, the middle plate 12 and the second side plate 13 are integrally formed and a weight-reducing chamber is formed inside, and the weight-reducing chamber is filled with a lightweight filler to ensure that the buoy 200 provides greater buoyancy for the offshore power generation platform 100.

[0034] In some embodiments, Figure 2 As shown, the first side plate 11 is provided with a first mounting hole 111 , the second side plate 13 is provided with a second mounting hole 131 , and the fastener 2 passes through the first mounting hole 111 and the second mounting hole 131 .

[0035] Therefore, after the fastener 2 is connected to each of the first side plate 11 and the second side plate 13, the first mounting hole 111 and the second mounting hole 131 realize radial limitation of the fastener 2 in the first mounting hole 111. After the buoy 200 is installed on the frame rod 3, it is more difficult for the fastener 2 to detach from the first side plate 11 and the second side plate 13 along the depth direction of the accommodating groove 14, and the installation reliability of the buoy 200 on the frame rod 3 is higher.

[0036] Specifically, the first mounting hole 111 and the second mounting hole 131 are both circular holes and are coaxial. The axial direction of the first mounting hole 111 and the second mounting hole 131 is consistent with the width direction of the receiving groove 14 .

[0037] In some embodiments, Figure 1 and Figure 2 As shown, the fastener 2 includes a screw rod 21 and a nut 22 . The screw rod 21 passes through the first mounting hole 111 and the second mounting hole 131 and is threadedly matched with the nut 22 .

[0038] That is, after the frame rod 3 is engaged in the receiving groove 14, the screw 21 is passed through the first mounting hole 111 and the second mounting hole 131 and threadedly engaged with the nut 22 to complete the installation of the buoy 200 on the frame rod 3. The installation of the buoy 200 on the frame rod 3 is convenient and quick.

[0039] Specifically, after the nut 22 is threadedly matched with the screw rod 21 and abuts against the second side plate 13 , and at the same time, the head of the screw rod 21 abuts against the first side plate 11 , it means that the buoy 200 is assembled on the frame rod 3 .

[0040] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the fastener 2 further includes a top screw 23 , and a threaded hole 221 is provided on the outer peripheral surface of the nut 22 . The top screw 23 is threadably matched with the threaded hole 221 and pressed against the rod portion of the screw rod 21 .

[0041] At this time, when the nut 22 wants to rotate relative to the screw rod 21, the friction between the top screw 23 and the rod portion of the screw rod 21 must also be considered. As a result, the nut 22 is less likely to loosen and detach from the screw rod 21, and the installation reliability of the buoy 200 on the frame rod 3 is higher.

[0042] It should be noted that each screw rod 21 may also be threadedly matched with two nuts 22 , and the two nuts 22 abut against each other, so as to further reduce the probability of the nuts 22 loosening and separating from the screw rod 21 .

[0043] In some embodiments, the fastener 2 includes a locating pin, a locating hole is provided on the rod of the screw rod 21, the locating hole extends radially along the screw rod 21, the locating pin fits in the locating hole, and part of the locating pin is located outside the locating hole and on the side of the nut 22 away from the second side plate 13.

[0044] At this time, the positioning pin can also prevent the nut 22 from being separated from the screw rod 21 , and can also ensure the installation reliability of the buoy 200 on the frame rod 3 .

[0045] In some embodiments, Figure 2 and Figure 4 As shown, the middle plate 12 is provided with a limiting hole 121 penetrating through the middle plate 12 along the second direction, and the frame rod 3 is provided with a limiting rod 4 for fitting in the limiting hole 121 .

[0046] The cooperation between the limiting hole 121 and the limiting rod 4 effectively fixes the buoy 200 and the frame rod 3 in the extension direction of the frame rod 3. The installation position of the buoy 200 on the frame rod 3 is highly reliable and will not slide accidentally along the extension direction of the frame rod 3 to affect the center of gravity deviation of the offshore power generation platform 100.

[0047] Specifically, the number of the limiting hole 121 is one, and the limiting hole 121 is preferably arranged at the center position of the middle plate 12 .

[0048] In some embodiments, the receiving groove 14 is a U-shaped groove, and the floating body 1 includes a shell and a lightweight filler. A U-shaped chamber is provided in the shell, and the lightweight filler is filled in the U-shaped chamber.

[0049] The provision of lightweight fillers ensures that the average density of the floating body 1 is smaller, thereby providing greater buoyancy for the offshore power generation platform 100 .

[0050] Specifically, the lightweight filler is preferably a waterproof plastic or silicone structure. When the opening on the shell connected to the U-shaped chamber is accidentally opened, the lightweight filler will also prevent external seawater from entering the U-shaped chamber, effectively ensuring that the float 200 provides stable and reliable buoyancy.

[0051] In some embodiments, the number of the fasteners 2 is at least two, and all the fasteners 2 are arranged at intervals along the first direction.

[0052] That is, the buoy 200 is limited on the frame rod 3 by at least two fasteners 2, and at least two fasteners 2 are arranged at intervals along the extension direction of the accommodating groove 14, so that the force on each fastener 2 is more uniform, and the fastener 2 is less likely to be deformed or broken due to excessive force, and the installation reliability of the buoy 200 on the frame rod 3 is higher.

[0053] Specifically, Figure 1-Figure 3 As shown, the number of the fasteners 2 is two.
