Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation equipment, and in particular to a semi-submersible floating platform and a marine photovoltaic power station. Background Technology

[0002] Unlike land, the ocean is more open and unobstructed under the same sunlight conditions, and has a longer sunshine duration and radiation, providing a good environmental foundation for photovoltaic power generation. However, offshore photovoltaic equipment is subject to the combined effects of various loads such as sea wind, waves, and currents, making it difficult to achieve stable power generation. At present, semi-submersible marine photovoltaic platforms with stable structural strength and high wind and wave resistance are mostly used to provide the power generation support foundation for photovoltaic modules. However, adjacent photovoltaic platforms often collide with each other due to wind, waves, and currents, which can not only damage the platform structure, but also affect the power generation efficiency and service life of photovoltaic modules.

[0003] Therefore, how to reduce the damage to the platform and photovoltaic modules caused by collisions between adjacent photovoltaic platforms is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a semi-submersible floating platform and a marine photovoltaic power station to reduce the damage to the platform and photovoltaic modules caused by collisions between adjacent photovoltaic platforms.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A semi-submersible floating platform includes platform units for carrying photovoltaic modules. At least two platform units are provided and fixedly connected as an integral structure. Each platform unit is provided with an anti-collision component, the outer side of which is a flexible structure. The anti-collision components of two adjacent platform units abut against each other in a cross structure, and two adjacent platform units have at least two pairs of anti-collision components on their docking plane. The at least two pairs of anti-collision components are evenly distributed on the docking plane of the platform units.

[0007] Preferably, in the above-mentioned semi-submersible floating platform, the platform unit includes a support frame and columns. Four columns are provided and located at the four corners of the support frame. The anti-collision components are fixedly provided on the columns, and at least two anti-collision components are provided at intervals along the height direction of the columns.

[0008] Preferably, in the above-mentioned semi-submersible floating platform, the anti-collision component includes a support component and an anti-collision part. The support component includes a connecting part and a mounting plate. The connecting part is fixedly connected to the column, and the anti-collision part is fixedly disposed on the mounting plate.

[0009] Preferably, in the above-mentioned semi-submersible floating platform, the connecting part is an I-beam structure, and several reinforcing ribs are fixedly welded between the connecting part and the mounting plate.

[0010] Preferably, in the above-mentioned semi-submersible floating platform, the mounting plate is fixedly connected to the support assembly along the length direction of the column, or the mounting plate is fixedly connected to the support assembly in a direction perpendicular to the column.

[0011] Preferably, in the above-mentioned semi-submersible floating platform, the anti-collision components of two adjacent platform units abut each other in a cross structure.

[0012] Preferably, in the above-mentioned semi-submersible floating platform, the column is provided with the anti-collision component in both the length and width directions of the support frame.

[0013] Preferably, in the above-mentioned semi-submersible floating platform, the mounting plate has holes, and the anti-collision part is fixed to the mounting plate by bolts.

[0014] Preferably, in the above-mentioned semi-submersible floating platform, the anti-collision part is a U-shaped fender rubber.

[0015] A marine photovoltaic power station includes a semi-submersible floating platform as provided in any of the above.

[0016] As can be seen from the above technical solution, this disclosure provides a semi-submersible floating platform, which is formed by splicing at least two platform units to form an integrated support structure, providing a stable bearing foundation for photovoltaic modules on the sea surface. The modular platform unit design facilitates offshore installation and maintenance. At the same time, the platform units are equipped with flexible anti-collision components, and adopt a cross-abutting anti-collision component layout, forming relative movement protection in two directions on the docking plane of adjacent platforms. This can achieve more effective anti-collision protection in complex marine environments and significantly reduce the risk of collision damage between platforms. In addition, at least two pairs of anti-collision components are set on the docking plane of the two platform units to avoid the risk of collision at other locations caused by the tilting of the platform units during single-point anti-collision, thereby improving the anti-collision effect and optimizing the structural stability of the semi-submersible floating platform.

[0026] The core of this application is to disclose a semi-submersible floating platform and a marine photovoltaic power station to reduce the damage to the platform and photovoltaic modules caused by collisions between adjacent photovoltaic platforms.

[0027] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, this disclosure provides a semi-submersible floating platform, which includes at least two platform units 10, spliced ​​together to form a platform structure. Specifically, the platform unit 10 refers to the basic module that carries photovoltaic equipment, which can be implemented using a steel frame structure and connected by welding or bolts to form an integral structure. Each platform unit 10 is also provided with an anti-collision component 20, and the outer side of the anti-collision component 20 is provided with a flexible structure to form a flexible contact surface, which can be implemented using polymer composite materials or rubber materials, absorbing impact energy through elastic deformation. Meanwhile, after the two platform units 10 are fixedly connected, their anti-collision components 20 form a cross-abutting structure. The cross-abutting structure means that the adjacent anti-collision components 20 form a spatially staggered contact rather than a directly aligned structure. The two anti-collision components 20 are at a certain angle so that when the platform unit 10 moves under the action of waves and slides along the direction of the two cross-abutting anti-collision components 20, it can still achieve abutting anti-collision due to the contact area of ​​the two cross-abutting anti-collision components 20. That is, relative movement protection in two directions is formed on the docking plane of the adjacent platforms, which can achieve more effective anti-collision protection in complex marine environments and significantly reduce the risk of collision damage between platforms.

[0029] Furthermore, when the two platform units 10 dock, there will be a docking plane. To further improve the anti-collision effect of the platform units 10, in the semi-submersible floating platform provided in this embodiment, adjacent platform units 10 have at least two pairs of anti-collision components 20 on their docking plane, and the two pairs of anti-collision components 20 are spaced apart. The two platform units 10 have at least two points on the docking plane, which are more stably protected by anti-collision contact, thus avoiding the risk of rigid collisions in other areas due to the two platform units 10 being tilted after contact caused by single-point force. Preferably, at least two pairs of anti-collision components 20 are evenly distributed on the docking plane of the platform units 10, and each pair of anti-collision components 20 undertakes a similar anti-collision area, thereby improving the uniformity of the effect of the anti-collision components 20.

[0030] Furthermore, in the semi-submersible floating platform provided in this disclosure, the platform unit 10 includes a support frame 110 and columns 120. The support frame 110 refers to the basic frame structure used to support the photovoltaic modules, specifically a rectangular or square steel frame, formed by welding or bolting to create a rigid whole, providing a stable mounting surface. Four columns 120 are provided at the four corners of the support frame 110. The columns 120 are support structures vertically fixed to the four corners of the support frame 110, specifically hollow steel pipes or H-beams, used to lift the platform unit 10. The overall height and bending stiffness of the column are determined, while providing an installation base for the anti-collision component 20. Correspondingly, the anti-collision component 20 is fixedly installed on the column 120, and at least two anti-collision components 20 are spaced apart in the height direction of the column 120. It should be noted that the anti-collision components 20 being spaced apart in the height direction means that the anti-collision parts 220 are distributed longitudinally along the column 120 and maintain a certain distance. Specifically, this can be achieved by layered installation, for example, by setting a set of anti-collision components 20 in the middle and top of the column 120 to cope with the collision risk under different water level conditions and reduce the probability of structural damage.

[0031] Based on the above embodiments, the anti-collision component 20 includes a support component 210 and an anti-collision part 220. The support component 210 is a transition structure for connecting the column 120 and the anti-collision part 220. It mainly includes a connecting part 2110 and a mounting plate 2120. The connecting part 2110 is a load-bearing member that is directly fixed to the column 120. Specifically, it can be made of I-beams or channel steel profiles. Its cross-sectional shape can improve the bending resistance and provide a stable connection foundation. The mounting plate 2120 is a planar support for fixing the anti-collision part 220. Specifically, it can be made of steel plate or alloy plate. Bolt holes can be provided on the surface to adapt to different specifications of the anti-collision part 220. It should also be noted that the anti-collision part 220 is a buffer component that absorbs external impact energy. Specifically, it can be made of rubber, polyurethane or composite material fender structure. In some embodiments, the anti-collision part 220 adopts a U-shaped cross-section to increase its deformation space and further improve the buffering effect of the anti-collision component 20.

[0032] To further optimize the above technical solution, in some embodiments of this disclosure, the connecting part 2110 is an I-beam structure to have good bending and compressive strength. Several reinforcing ribs 2130 are fixedly welded between the connecting part 2110 and the mounting plate 2120. Specifically, triangular or rectangular steel plates can be used to form a support structure between the web of the I-beam and the mounting plate 2120 by welding. This can suppress the deformation of the connecting part 2110 under dynamic load and improve the service life of the support assembly 210.

[0033] Furthermore, it should be noted that in the semi-submersible floating platform provided in the embodiments of this disclosure, such as Figure 4 As shown, the mounting plate 2120 is fixedly connected to the support assembly 210 along the length of the column 120 to form a vertical anti-collision structure, or as... Figure 5 As shown, the mounting plate 2120 is fixedly connected to the support assembly 210 in a direction perpendicular to the column 120 to form a lateral anti-collision structure. The two installation methods enable the two platform units 10 to form a vertically intersecting cross-shaped abutment structure, thus achieving a stable anti-collision effect in the sea environment of lateral translation and heave.

[0034] Furthermore, in the semi-submersible floating platform provided in this embodiment, the column 120 is provided with anti-collision components 20 in both the length and width directions of the support frame 110. It should be noted that the length and width directions of the support frame 110 refer to two mutually perpendicular extension directions of the main structure of the platform unit 10, which can be defined by the adjacent sides of a rectangular or square frame. The column 120 has an installation position on the side away from the platform unit 10 for the installation of the anti-collision components 20. Since the column 120 is provided with anti-collision components 20 in both the length and width directions of the support frame 110, when the platform unit 10 docks with other platform units 10 in its length and width directions, the anti-collision components 20 provide anti-collision protection, thereby improving the structural expansion freedom of the semi-submersible floating platform.

[0035] In addition, in some embodiments of this disclosure, the mounting plate 2120 has openings, which can be through holes or threaded holes machined on the surface of the plate. The anti-collision part 220 is fixed to the mounting plate 2120 by bolts, so as to realize the convenient replacement of the anti-collision part 220 and reduce the maintenance difficulty of the anti-collision assembly 20.

[0036] Furthermore, in some embodiments of this disclosure, the anti-collision part 220 is a U-shaped fender rubber. The U-shaped cross-section means that the cross-sectional shape of the anti-collision part 220 is an outward-opening arc-shaped groove structure, which can disperse impact force through deformation and form a multi-directional buffer space under pressure. The fender rubber is made primarily of high-molecular synthetic rubber, specifically styrene-butadiene rubber or neoprene rubber with added anti-aging agents. It possesses elastic recovery characteristics and seawater corrosion resistance, making it suitable for marine environments where repeated collision loads are applied.

[0037] Furthermore, this disclosure also provides a marine photovoltaic power station, which includes a semi-submersible floating platform provided in any of the above embodiments to support the photovoltaic modules. It should be noted that since the semi-submersible floating platform has the technical effects provided in any of the above embodiments, the marine photovoltaic power station also has the technical effects provided in any of the above embodiments, and will not be repeated here.
