[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] See also Figure 1 , Figure 2 A photovoltaic power generation device is used for an offshore floating photovoltaic power generation system. The photovoltaic power generation device includes a floating body component 120, a photovoltaic component 110 and a connecting component. A mounting plate 121 is provided on the floating body component 120. The photovoltaic component 110 is mounted on the mounting plate 121. The connecting component is arranged between the floating body component 120 and the photovoltaic component 110, and the connecting component includes an adhesive layer. The adhesive layer is arranged on the mounting plate 121, and the photovoltaic component 110 can be bonded to the adhesive layer.

[0035] Specifically, when using the photovoltaic power generation device of this embodiment, the photovoltaic module 110 is directly bonded to the adhesive layer, and the adhesive layer is set on the mounting plate 121, that is, the photovoltaic module 110 is directly attached to the floating body module 120 to complete the installation. After that, the photovoltaic power generation device of this embodiment is placed on the target sea surface, and subsequent operations can be carried out.

[0036] The connection between the photovoltaic module 110 and the floating module 120 is set to be bonded by an adhesive layer, which can effectively simplify the installation process. Adhesive installation is usually faster and simpler than other mechanical fastener installation methods, reducing the time and labor costs of on-site construction, and helping to improve construction efficiency. In addition, the use of adhesive materials instead of metal fasteners can reduce the weight of the entire floating system, reduce the pressure of the floating structure, improve the buoyancy efficiency of the system, and reduce the burden on the floating structure. Furthermore, connecting by bonding reduces the use of mechanical parts and reduces the maintenance requirements caused by corrosion or loosening of metal parts, which can improve the stability and reliability of this embodiment.

[0037] Especially in deep sea areas, extreme weather such as strong winds, huge waves, and salt spray occurs frequently. As a non-metallic part, the adhesive layer usually has good corrosion resistance compared to metal parts. Connecting the photovoltaic assembly 110 and the floating assembly 120 through the adhesive layer can effectively prevent seawater from eroding this embodiment and extend the service life. Connecting by adhesive can also avoid local stress concentration of the photovoltaic assembly 110 caused by mechanical fixings during installation or long-term use. The adhesive method can distribute pressure more evenly and reduce physical damage to the photovoltaic panel.

[0038] In one embodiment, the photovoltaic assembly 110 is illustratively configured as a flexible assembly. The flexible photovoltaic assembly 110 is easy to bend and can be directly attached to the surface of the floating body, which simplifies the fixings and complex installation procedures required in traditional installation, reduces construction difficulty and time, and improves installation efficiency.

[0039] It should be noted that in the offshore environment, the adaptability of the flexible component enables the photovoltaic component 110 to fit more closely to the surface of the floating component 120. Compared with the connection method of metal fixings, the connection method of this embodiment is thinner. In this way, during photovoltaic power generation operations, even if this embodiment fluctuates under the action of waves, adjacent photovoltaic power generation equipment will not block each other, thereby avoiding the loss of power generation efficiency caused by mutual blocking of the photovoltaic components 110.

[0040] The photovoltaic component 110 is configured as a flexible component. In subsequent operations, if part of the photovoltaic component 110 is damaged and needs to be replaced, it is easier to operate and replace, thereby reducing the difficulty of inspection and maintenance of the present embodiment.

[0041] In one embodiment, the adhesive layer includes a first adhesive layer and a second adhesive layer, the first adhesive layer is arranged on the mounting plate 121, the second adhesive layer is arranged on the photovoltaic module 110, and the first adhesive layer can be bonded to the second adhesive layer. In this way, when installing the photovoltaic power generation device provided by this embodiment and attaching the mounting plate 121 and the photovoltaic module 110 to each other, it is easier to align the photovoltaic module 110 with the mounting plate 121 and attach them to a suitable position, thereby improving the adhesive strength and avoiding affecting the attachment of the photovoltaic module 110 and the mounting plate 121 due to installation errors or misoperation.

[0042] In one embodiment, illustratively, a mounting portion is provided on the floating assembly 120, the mounting portion is provided on a horizontal plane, the mounting plate 121 is provided on the mounting portion, and a waterproof gap is provided between the mounting plate 121 and the mounting portion. The provision of a waterproof gap can, firstly, effectively prevent seawater from directly contacting the back of the photovoltaic assembly 110, or the bonding layer between the photovoltaic assembly 110 and the floating assembly 120, avoid short circuit, corrosion or bonding failure of electronic equipment caused by water penetration, and extend the service life of the photovoltaic assembly 110 and the bonding material. Secondly, the environment in the deep sea area is complex and changeable. When the floating assembly 120 experiences extreme weather, it will rise and fall and swing left and right with the waves. The provision of a waterproof gap between the mounting plate 121 and the mounting portion can allow the floating assembly 120 to produce a certain degree of deformation, reduce the mechanical stress on the assembly by deformation, increase the durability and stability of the system, and the deformation will not affect the floating support effect of the floating assembly 120, and will not affect the normal power generation operation of the photovoltaic assembly 110.

[0043] It should be noted that the photovoltaic module 110 will generate heat during the power generation operation, and the heat will gradually accumulate on the back of the photovoltaic module 110. Providing a waterproof gap between the mounting plate 121 and the mounting portion can help dissipate heat from the back of the photovoltaic module 110 and reduce efficiency loss due to high temperature, especially in high-humidity marine environments. This ensures that the photovoltaic module 110 can operate normally and will not be affected by factors such as temperature and humidity, resulting in loss of power generation efficiency.

[0044] In one embodiment, the mounting plate 121 is illustratively arranged tilted relative to the mounting portion. The mounting plate 121 is tilted, that is, the photovoltaic module 110 is tilted, so that by controlling the tilt direction and tilt angle, the photovoltaic module 110 can be better oriented toward the sun, thereby improving the power generation efficiency of the photovoltaic module 110. Furthermore, by coordinating the waterproof gap and the tilt setting, the photovoltaic module 110 can be effectively prevented from contacting with seawater, and can also resist the impact of waves to a certain extent, thereby extending the service life of the photovoltaic module 110.

[0045] In one embodiment, for example, Figure 3As 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, thereby better supporting 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.

[0046] 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 130, which is arranged at the edge of the mounting plate 121, and the connecting plate 130 can be connected to adjacent floating body assemblies 120. By providing the connecting plate 130, multiple floating body assemblies 120 can be connected to each other through the connecting plate 130, 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.

[0047] In one embodiment, for example, Figure 3 As shown, a plurality of connecting plates 130 are provided, and the plurality of connecting plates 130 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 130 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.

[0048] In one embodiment, for example, Figure 3 As shown, a connector 131 is provided on the connecting plate 130, and a plurality of connectors 131 are provided, and the plurality of connectors 131 are evenly distributed on the connecting plate 130. By providing a plurality of connectors 131 between every two connecting plates 130, the structural stability of the entire photovoltaic array can be significantly enhanced, forming a more solid overall frame. In this way, even in the event of severe sea conditions such as strong winds and large waves, the shaking and displacement of the overall frame can be effectively reduced, and the photovoltaic assembly 110 can be protected from damage. By providing a plurality of connectors 131, the forces acting on the connecting plate 130, including wind loads, wave impact forces, and the deadweight of the photovoltaic assembly 110, can be more evenly distributed, thereby avoiding local stress concentration, reducing the risk of damage at the connector 131, and extending the service life of this embodiment.

[0049] In addition, the provision of multiple connectors 131 can improve the risk resistance of this embodiment. That is to say, if a problem occurs in a connector 131 and it needs to be repaired or replaced, since multiple connectors 131 are provided between the connecting plates 130, the overall structure of this embodiment can still remain stable, which provides time and conditions for repairing or replacing individual connectors 131 and reduces the risk of the entire system being paralyzed due to a single failure.

[0050] It should be noted that the structure of the connector 131 is not limited in this embodiment. That is to say, the connecting plate 130 can adaptively select a suitable connector 131 for connection according to the workpiece to be connected, so as to improve the reliability, rationality and stability of the connection. Exemplarily, when the floating body assembly 120 and the floating body assembly 120 are connected to each other, a hinged plate connection can be adopted, that is, the first hinged plate is installed on the connecting plate 130 of the floating body assembly 120, and the second hinged plate is installed on the connecting plate 130 of the adjacent floating body assembly 120, and the first hinged plate is hingedly connected to the second hinged plate. In this way, when the present embodiment encounters waves, since the floating body assembly 120 and the floating body assembly 120 are flexibly connected by the hinged plate, the floating body assembly 120 can rise and fall with the waves, thereby improving the wave resistance of the present embodiment, thereby making the structure of the present embodiment more reasonable and reliable.

[0051] Example 2

[0052] This embodiment also provides an offshore floating photovoltaic power generation system, including any one of the photovoltaic power generation devices in the above embodiments, wherein a plurality of photovoltaic power generation devices are provided, and the plurality of photovoltaic power generation devices are interconnected to form a main floating body, and a mooring floating body 200 is also provided at the edge of the main floating body.

[0053] Specifically, when encountering waves in this embodiment, the waves first hit the mooring float 200. After the mooring float 200 disperses, dissipates energy, and absorbs the waves, the waves will contact the main float, and the mooring float 200 will protect the main float and the photovoltaic module 110.

[0054] It is worth mentioning that the main floating body is composed of multiple photovoltaic power generation devices connected to each other, and the form and number of the connectors 131 between the photovoltaic power generation devices can be adaptively selected according to the actual situation to cope with different working conditions. The mooring buoy 200 set at the edge of the main floating body and the connector 131 between the main floating body, the form and number of the connector 131 can also be selected according to the actual situation. Exemplarily, a flexible rope can be used as the connector 131 between the main floating body and the mooring buoy 200. The flexible rope can be used to connect the mooring buoy 200 and the main floating body, which can limit the range of relative displacement between the mooring buoy 200 and the main floating body, making it easier for the mooring buoy 200 to protect the main floating body, while not limiting the degree of freedom of the mooring buoy 200. After the waves hit the mooring buoy 200, the mooring buoy 200 can swing and deflect arbitrarily within the limit of the flexible rope according to the direction and strength of the waves, so that the mooring buoy 200 can better play the role of dispersing, dissipating energy and absorbing the waves, thereby weakening and mitigating the waves and protecting the main buoy and photovoltaic components 110.

[0055] 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.
