[0032] Example 1

[0033] This embodiment provides a photovoltaic power generation device to solve the problem in the related art that the photovoltaic power generation device has a cumbersome and complicated installation method and is not convenient for use in deep sea areas.

[0034] Please refer to 1. Figure 2 A photovoltaic power generation device is used for an offshore floating photovoltaic power generation system, comprising a floating assembly 120, a photovoltaic assembly 110 and a connection assembly. A mounting plate 121 is provided on the floating assembly 120. The photovoltaic assembly 110 is mounted on the mounting plate 121. The connection assembly comprises a rigid bracket 200, the rigid bracket 200 is provided on the mounting plate 121, and the photovoltaic assembly 110 can be detachably mounted on the rigid bracket 200.

[0035] Specifically, when using the photovoltaic power generation equipment of this embodiment, the rigid support 200 is installed on the mounting plate 121, and the photovoltaic component 110 is installed on the rigid support 200. After that, the floating component 120 is placed on the target sea surface, and the photovoltaic power generation operation can be carried out normally.

[0036] The photovoltaic assembly 110 is installed on the floating assembly 120 through the rigid bracket 200, which can provide stable support for the photovoltaic assembly 110, reduce the shaking and displacement of the photovoltaic assembly 110 caused by wave fluctuations, wind or other external forces in deep sea areas, maintain the relative stability of the photovoltaic assembly 110 and the floating assembly 120, thereby improving the stability and durability of the entire system.

[0037] It should be noted that the rigid bracket 200 can ensure that the photovoltaic component 110 is accurately set according to construction requirements and design requirements, so as to accurately set the light capture angle of the photovoltaic component 110 according to actual working conditions, geographical location and other factors to improve the photoelectric conversion efficiency of the photovoltaic component 110.

[0038] In deep sea areas, there are many extreme weather conditions such as strong winds and huge waves. The rigid bracket 200 can effectively transmit wind force to the floating structure, disperse wind load, reduce the direct impact of strong wind on the photovoltaic module 110, and enhance the overall wind resistance of the system. In addition, compared with the flexible connection, the rigid bracket 200 reduces the mobility of the connection part, and also avoids the loosening, wear or damage of the connection parts during long-term operation, which reduces the maintenance and repair requirements of this embodiment, making this embodiment suitable for use on the sea surface in deep sea areas.

[0039] In one embodiment, for example, Figure 1 , Figure 2 As shown, the rigid support 200 is configured as an L-shaped plate, and the rigid support 200 includes a fixed end 210 and a fixed surface 220. The fixed end 210 abuts against the mounting plate 121, and the photovoltaic module 110 is mounted on the fixed surface 220. By configuring the rigid support 200 as an L-shaped plate, it is possible to reduce the amount of material used and the production and installation costs while ensuring the structural strength. It is also beneficial to reduce the weight of the rigid support 200 and reduce the load requirement for the floating assembly 120. By installing the photovoltaic assembly 110 on the fixed surface 220, a wider support area can be provided for the photovoltaic assembly 110 through the fixed surface 220, and the connection strength between the photovoltaic assembly 110 and the floating assembly 120 can be increased, thereby enhancing the overall stability and wind and wave resistance of this embodiment, and reducing the vibration of the photovoltaic assembly 110 under the impact of waves.

[0040] It is worth mentioning that setting the rigid support 200 as an L-shaped plate can keep the space between the photovoltaic component 110 and the floating component 120 open, which facilitates the cleaning, inspection and maintenance of the components of this embodiment and reduces the difficulty of operation for operators during maintenance.

[0041] In deep sea areas, the working environment is more complicated. The rigid bracket 200 is set as an L-shaped plate, so that the present embodiment can adjust the rigid bracket 200 according to the environmental conditions of different sea areas, such as wind speed, wave height, etc., such as by adjusting the length, width or reinforcement design of the L-shaped bracket to meet the stability and durability requirements in a specific environment.

[0042] In one embodiment, for example, Figure 2 As shown, the fixed end 210 is integrally arranged with the mounting plate 121. The rigid bracket 200 is integrally arranged with the mounting plate 121 of the floating assembly 120, which can enhance the connection strength and stability between the floating assembly 120 and the photovoltaic assembly 110, reduce the number of connection points, and reduce the risk of affecting the normal operation of this embodiment due to failure of the connection. Secondly, the integrated setting can reduce the steps of on-site assembly, simplify the construction process, and reduce installation time and cost.

[0043] Especially in deep sea areas, the number of connection points is reduced, which avoids the problem of seawater corrosion of movable connecting parts; reducing installation time and cost, enabling the present embodiment to be quickly deployed in a working environment that is not convenient for construction, improving the environmental adaptability of the present embodiment, and making the present embodiment suitable for use in deep sea areas.

[0044] In one embodiment, for example, Figure 2 As shown, a plurality of mounting holes are provided on the fixing surface 220, so that the photovoltaic module 110 can be directly connected through the reserved mounting holes, the installation process is standardized, and the installation difficulty is reduced.

[0045] In one embodiment, for example, Figure 1 As shown, a plurality of rigid brackets 200 are arranged on the mounting plate 121, and the plurality of rigid brackets 200 are arranged in parallel. The plurality of rigid brackets 200 arranged in parallel can effectively improve the connection strength between the floating body assembly 120 and the photovoltaic assembly 110. When the present embodiment is impacted by strong winds or waves, the local overload of the rigid bracket 200 can be avoided, and the weight and external load of the photovoltaic assembly 110 can be more evenly distributed, which significantly improves the overall stability and the ability to resist external forces of the present embodiment, reduces the risk of relative displacement or deformation between the photovoltaic assembly 110 and the floating body assembly 120, and prolongs the service life of the present embodiment.

[0046] In one embodiment, there are two rigid supports 200 arranged in parallel, and the heights of the two rigid supports 200 are different. In this way, after the photovoltaic assembly 110 is installed on the rigid supports 200, due to the different heights of the two rigid supports 200, the photovoltaic assembly 110 will be tilted. By controlling the tilt direction and tilt angle, the photovoltaic assembly 110 can be better oriented toward the sun, thereby improving the power generation efficiency of the photovoltaic assembly 110.

[0047] In one embodiment, for example, Figure 3 As shown, the floating assembly 120 includes a floating body and a reinforcement 123; a cavity 122 is provided in the floating body, and the reinforcement 123 is provided in the cavity 122, and the reinforcement 123 can support the cavity 122. The cavity 122 structure can effectively improve the buoyancy that the floating structure can provide, so as to better support the photovoltaic assembly 110. The cavity 122 combined with the internal reinforcement 123 can greatly improve the structural strength and bending resistance of the floating assembly 120 without significantly increasing the center of gravity of the floating body, so that the floating assembly 120 can withstand greater external force impacts, such as dynamic loads caused by strong winds and huge waves in the deep sea, and improve the stability and wave resistance of this embodiment.

[0048] In one embodiment, for example, Figure 3 As shown, a plurality of reinforcement members 123 are arranged in the cavity 122, and the position of the reinforcement members 123 in the cavity 122 corresponds to the position of the rigid support 200 on the mounting plate 121. The plurality of reinforcement members 123 are arranged in the cavity 122, which can more accurately control and optimize the weight distribution and buoyancy center of the floating assembly 120 while improving the overall strength of the floating assembly 120, so that the force of the floating assembly 120 is more uniform, local overload is reduced, and the service life is extended. The reinforcement members 123 are arranged corresponding to the position of the rigid support 200, that is, the reinforcement members 123 provide a force point for the rigid support 200, and support and reinforce the rigid support 200, so that the rigid support 200 can effectively transfer and disperse the external force on the photovoltaic assembly 110 to the main structure of the floating assembly 120, and enhance the rigidity and stability of the overall structure of the floating assembly 120, avoid deformation of the floating assembly 120, and ensure that the present embodiment can still maintain a good working state under severe sea conditions.

[0049] In one embodiment, for example, Figure 3 As shown, the mounting plate 121 is arranged on the floating body, and the floating body is also provided with a connecting plate, which is arranged at the edge of the mounting plate 121, and can be connected to adjacent floating body assemblies 120. By providing the connecting plate, multiple floating body assemblies 120 can be connected to each other through the connecting plate, and multiple interconnected floating body assemblies 120 can form an integral structure, i.e., the main floating body, thereby enhancing the stability of the entire photovoltaic assembly 110 array, improving the resistance of this embodiment to extreme weather in deep sea areas, protecting the photovoltaic assembly 110 from damage, and maintaining power generation efficiency.

[0050] In one embodiment, for example, Figure 3As shown, a plurality of connecting plates are provided, and the plurality of connecting plates are sequentially connected end to end to form a closed frame, and the mounting plate 121 is provided on the side of the closed frame. The connecting plates form a closed frame and the mounting plate 121 is provided on the side of the closed frame, which can make the structure of the present embodiment more reasonable and stable. The resistance of the present embodiment to extreme weather in deep sea areas is improved, and the present embodiment is ensured to have sufficient structural strength, thereby increasing the service life of the present embodiment.

[0051] Exemplarily, in this embodiment, the floating assembly 120 is configured as a rectangular plate, that is, four connecting plates are provided, the four connecting plates constitute a rectangular frame, and the mounting plate 121 is provided on the side of the rectangular frame. In this way, the floating assembly 120 is convenient for modular design, easy for standardization and mass production, and reduces manufacturing costs. The geometric shape of the rectangular plate facilitates accurate calculation and control of the buoyancy distribution of the floating assembly 120, ensuring that the photovoltaic assembly 110 floats stably on the water surface. Furthermore, the floating assembly 120 is configured as a rectangular plate, which is also convenient for interconnection with other floating assemblies 120, that is, multiple photovoltaic power generation devices are interconnected to form a photovoltaic power generation array, thereby improving the overall stability and wave resistance, and facilitating deep offshore photovoltaic power generation operations.

[0052] Example 2

[0053] This embodiment also provides an offshore floating photovoltaic power generation system, including the photovoltaic power generation equipment in any one of the above embodiments, wherein a plurality of photovoltaic power generation equipment are provided, and the plurality of photovoltaic power generation equipment are interconnected to form a main floating body, and a mooring floating body 300 is also provided at the edge of the main floating body.

[0054] Specifically, when encountering waves in this embodiment, the waves first hit the mooring float 300. After the mooring float 300 disperses, dissipates energy, and absorbs the waves, the waves will contact the main float, and the mooring float 300 will protect the main float and the photovoltaic module 110.

[0055] It should be noted that, in this embodiment, multiple photovoltaic power generation devices are connected by flexible connectors, and the main buoy and the mooring buoy 300 are also connected by flexible connectors. When waves hit this embodiment, the waves first contact the mooring buoy 300. Since the mooring buoy 300 and the main buoy are connected to each other by flexible connectors, the mooring buoy 300 has an energy absorption effect. That is, after the waves hit the mooring buoy 300, the mooring buoy 300 can dissipate the impact of the waves and absorb part of the impact of the waves through overall deformation and displacement.

[0056] The main buoy is composed of a plurality of photovoltaic power generation devices connected by flexible connectors, and the main buoy also possesses the characteristics possessed by the mooring buoy 300. That is to say, when the waves hit this embodiment, the waves are first refracted, absorbed, and dispersed through the mooring buoy 300 at the outer edge, thereby reducing the energy carried by the waves and alleviating the impact force of the waves. After the waves pass through the mooring buoy 300, the main buoy can also refract, absorb, and disperse the waves, further reducing the energy carried by the waves and protecting the photovoltaic components 110 installed on the main buoy.

[0057] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
