Offshore photovoltaic can overcome many limitations of traditional photovoltaic, and under the background of striving for "double carbon", offshore photovoltaic power station has good application prospect, and the development of offshore photovoltaic power generation will become an inevitable trend. However, the sea environment is more severe than the inland environment, especially the influence of sea waves on floating power stations is particularly severe. In the prior art, photovoltaic panels are usually fixed on buoyancy capsules, so that the photovoltaic panels can float on the sea surface; and multiple buoyancy capsules are connected to form an offshore floating photovoltaic power station. However, under the action of sea waves, overturning often occurs. This makes the offshore floating photovoltaic power station easily damaged, and the maintenance cost is very high. In order to make the service life of the offshore floating photovoltaic power station longer and the maintenance cost lower, a photovoltaic support with stronger sea wave resistance is needed.

In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0029] The present application provides a lotus leaf bionic semi-submersible photovoltaic support.

[0030] In the embodiments of the present application, with reference to Figure 1 and Figure 3 The lotus leaf bionic semi-submersible photovoltaic support comprises:

[0031] The buoyancy member 10 is arranged at a position below the water surface in use, and is used to provide buoyancy;

[0032] The support rod 20 is connected to the buoyancy member 10 at one end;

[0033] The photovoltaic panel support assembly is connected to the end of the support rod 20 away from the buoyancy member 10, and the photovoltaic panel support assembly is arranged above the water surface in use.

[0034] The buoyancy member 10 can be made of a material with a density smaller than water, such as foamed plastic, wood, etc. The buoyancy member 10 can also be hollow, in which case the outer wall of the buoyancy member 10 can be made of plastic or metal.

[0035] According to the law of buoyancy, the buoyancy is equal to the volume of the object that displaces water, so the volume of the buoyancy member 10 that provides buoyancy will inevitably be large. In the traditional photovoltaic assembly, the buoyancy member 10 floats on the water surface, and the large volume of the buoyancy member 10 makes the photovoltaic assembly prone to overturning under the impact of waves, and even damaged after colliding with other photovoltaic assemblies. However, in the present application, the buoyancy member 10 is arranged underwater and is not affected by waves, so it has stronger wave resistance.

[0036] Since the buoyancy member 10 is responsible for displacing water to provide buoyancy, the support rod 20 can be made of a material with high rigidity, such as steel, high-strength plastic material, or some material with high rigidity, such as glass fiber, carbon fiber, etc. In this way, the support rod 20 has sufficient strength and is relatively thin, so that the support rod 20 has a small wave-affected area and has strong stability in waves.

[0037] The photovoltaic panel support assembly is used to fix the photovoltaic panel 30 to the support rod 20. The photovoltaic panel support assembly can be a screw, so that a mounting hole is reserved on the photovoltaic panel 30, and a threaded hole is arranged on the end of the support rod 20 away from the buoyant member 10, so that the screw passes through the mounting hole and is screwed with the support rod 20, so that the photovoltaic panel 30 is mounted on the support rod 20. The photovoltaic panel support assembly can also be a metal plate. In this embodiment, the support rod 20 is also made of metal. The photovoltaic panel support assembly is connected with the support rod 20 by welding, and is fixed with the photovoltaic panel 30 by a screw, so that the photovoltaic panel 30 is indirectly connected with the support rod 20.

[0038] The photovoltaic panel 30 is used to generate electricity by photovoltaic effect. The photovoltaic panel 30 inevitably needs to have a large surface area. The photovoltaic panel support assembly is arranged above the sea level, so that the photovoltaic panel 30 is also above the sea level, so that the photovoltaic panel 30 will not be impacted by the sea waves, and the stability of the photovoltaic panel 30 is ensured.

[0039] To ensure that the lotus-leaf bionic semi-submersible photovoltaic support will not overturn, the center of gravity of the lotus-leaf bionic semi-submersible photovoltaic support is lower than the center of action of the buoyancy in use, so that the lotus-leaf bionic semi-submersible photovoltaic support can stand straight in water. Alternatively, the scheme of the first anchor block 40 and the first anchor chain 50 mentioned below can also be used. When the first anchor block 40 pulls the buoyant member 10 through the first anchor chain 50, it can ensure that the lotus-leaf bionic semi-submersible photovoltaic support can stand straight.

[0040] The photovoltaic panel support assembly and the photovoltaic panel 30 are combined to be similar to a lotus leaf, and the support rod 20 is similar to a lotus stem. By imitating the shape of a lotus leaf, the lotus-leaf bionic semi-submersible photovoltaic support can be stable in the wind and waves like a lotus leaf in the wind and waves, so as to improve the wind and wave resistance of the lotus-leaf bionic semi-submersible photovoltaic support.

[0041] Reference Figure 1 Optionally, in use, the distance between the buoyant member 10 and the water surface is greater than or equal to 1 m and less than or equal to 12 m; and / or

[0042] In use, the distance between the photovoltaic panel support assembly and the water surface is greater than or equal to 1 m and less than or equal to 10 m.

[0043] The distance between the buoyancy member 10 and the water surface is too small, which causes the buoyancy member 10 to be affected by the sea waves too much; the distance between the buoyancy member 10 and the water surface is too large, which causes the length of the support rod 20 required to be too long, so that the support rod 20 is easy to bend; and when the distance between the buoyancy member 10 and the water surface is greater than or equal to 1 m and less than or equal to 10 m, the above defects can be overcome. The distance between the photovoltaic panel support assembly and the water surface is too small, so that the photovoltaic panel 30 is easily impacted by the sea waves; the distance between the photovoltaic panel support assembly and the water surface is too large, which causes the length of the support rod 20 required to be too long, so that the support rod 20 is easy to bend; and when the distance between the photovoltaic panel support assembly and the water surface is greater than or equal to 1 m and less than or equal to 10 m, the above defects can be overcome.

[0044] Reference Figure 1 Optionally, the lotus-leaf bionic semi-submersible photovoltaic support further comprises a first anchor block 40 and a first anchor chain 50, one end of the first anchor chain 50 is connected with the end of the support rod 20 away from the photovoltaic panel support assembly, and the other end of the first anchor chain 50 is connected with the first anchor block 40; in use, the first anchor block 40 is arranged on the water bottom. The first anchor block 40 can stabilize the position of the lotus-leaf bionic semi-submersible photovoltaic support and prevent it from drifting with the scouring of the sea waves. Since the support rod 20 is a load-bearing member for bearing the photovoltaic panel 30 and the photovoltaic panel support assembly and other structures, it has large strength, and the connection of the anchor chain with the support rod 20 is conducive to improving the overall structural strength of the photovoltaic support.

[0045] Reference Figure 1 and Figure 3 Optionally, a through hole is arranged on the buoyancy member 10, and the through hole is used for allowing the end of the support rod 20 away from the photovoltaic panel support assembly to pass through and be exposed outside the buoyancy member 10. Since the anchor chain is connected with the end of the support rod 20 away from the photovoltaic panel support assembly, the end of the support rod 20 connected with the anchor chain passes through the buoyancy member 10, which can make the force point of the anchor block on the support rod 20 be below the gravity center of the buoyancy force in the gravity direction, so as to stabilize the photovoltaic support function frame.

[0046] Reference Figures 1 to 3 Optionally, the photovoltaic panel support assembly comprises a support frame 60, the support frame 60 comprises a plurality of frame rods 61, the plurality of frame rods 61 are connected with each other to form a photovoltaic panel mounting surface, and the support frame 60 is connected with the support rod 20. The support frame 60 is a frame structure, has high strength and small wind area, and thus can remain stable in the wind and waves.

[0047] Reference Figures 1 to 3Optionally, the photovoltaic panel support assembly further comprises a diagonal support rod 70, one end of the diagonal support rod 70 is connected with the support rod 20, and the other end of the diagonal support rod 70 is connected with the support frame 60; the extension direction of the diagonal support rod 70 is arranged at an angle with the extension direction of the support rod 20. The diagonal support rod 70 provides additional support for the support frame 60 to improve the strength of the connection between the support frame 60 and the support rod 20, and to avoid the stress between the support frame 60 and the support rod 20 being too large to break when the photovoltaic panel 30 is subjected to wind. The end of the diagonal support rod 70 connected with the support frame 60 can be connected to the edge of the support frame 60 to strengthen the support of the diagonal support rod 70 on the support frame 60.

[0048] Reference Figure 1 Optionally, the shape of the buoyant member 10 is configured in a cylindrical shape, and the axis direction of the buoyant member 10 is the same as the extension direction of the support rod 20. The buoyant member 10 is arranged below the water surface, and when water flow along the horizontal plane occurs underwater, the water surface of the buoyant member 10 is a curved surface, so the force is small and it is not easy to be pushed by the water flow, ensuring the stability of the position of the lotus-leaf bionic semi-submersible photovoltaic support. When the buoyant member 10 is displaced in the height direction due to the action force of the support rod 20 (for example, when the photovoltaic panel 30 is subjected to external impact), the water surface of the buoyant member 10 is a plane, and the resistance is large, which provides damping for the whole lotus-leaf bionic semi-submersible photovoltaic support, so that the movement of the lotus-leaf bionic semi-submersible photovoltaic support in the height direction is rapidly dissipated, ensuring the stability of the position of the photovoltaic panel 30 in the height direction.

[0049] Reference Figure 1 Optionally, the normal direction of the plane where the photovoltaic panel mounting surface is located is the same as the extension direction of the support rod 20. On the water surface, due to the resistance of water to airflow, the wind often blows in the horizontal direction at the position near the water surface; when the plane where the photovoltaic panel mounting surface is located is perpendicular to the extension direction of the support rod 20, in use, the photovoltaic panel 30 is parallel to the horizontal plane, the wind area is small, and the stability of the photovoltaic panel 30 in the wind is improved.

[0050] Reference Figure 4 The present application also provides a lotus-leaf bionic semi-submersible photovoltaic support array structure, which comprises a plurality of lotus-leaf bionic semi-submersible photovoltaic supports and a connecting member. The specific structure of the lotus-leaf bionic semi-submersible photovoltaic support is referred to the above-mentioned embodiments. Since the lotus-leaf bionic semi-submersible photovoltaic support array structure adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. The connecting member is used to connect the plurality of lotus-leaf bionic semi-submersible photovoltaic supports.

[0051] In actual use, usually multiple lotus leaf bionic semi-submersible photovoltaic support are combined into a lotus leaf bionic semi-submersible photovoltaic support array structure to generate electricity. The connecting piece can connect multiple lotus leaf bionic semi-submersible photovoltaic supports, thereby forming a lotus leaf bionic semi-submersible photovoltaic support array structure. The connecting piece can be a connecting plate, the plane of the connecting plate being perpendicular to the extension direction of the connecting rod 80, and the connecting plate being provided with a through hole through which the connecting rod 80 passes to be fixed with the connecting plate; the connecting plate can be hollowed out to reduce weight.

[0052] Reference Figure 4 Optionally, the connecting piece includes a connecting rod 80, one end of the connecting rod 80 being connected with the support rod 20 of one lotus leaf bionic semi-submersible photovoltaic support, and the other end of the connecting rod 80 being connected with the support rod 20 of another lotus leaf bionic semi-submersible photovoltaic support. The rod-shaped structure has small wind-affected area in the wind and small water-affected area in the water, and can maintain high stability in the fluid to avoid the impact of the fluid on the lotus leaf bionic semi-submersible photovoltaic support array structure. In addition, the connecting rod 80 can have multiple rods, and one connecting rod 80 can also be connected with multiple support rods 20 at the same time. The connecting rod 80 can be arranged underwater or on the water surface. The connecting rods 80 can also be provided with stabilizing rods, the stabilizing rods connecting different connecting rods 80 and forming a frame structure with the connecting rods 80 as shown in Figure 4 , so as to improve the stability of the connection. In particular, the connecting rods 80 can be arranged in pairs, the connecting rods 80 in a pair being parallel to each other, and the two ends of each connecting rod 80 in a pair being connected with the same two support rods 20, so that the two support rods 20 and the connecting rods 80 in a pair form a four-bar linkage structure, and the connecting rods 80 and the support rods 20 are rotationally connected, so that the connecting rods 80 are flexibly connected with each other, thereby reducing the deformation of the connecting rods 80 caused by the relative displacement between the support rods 20 due to wind and waves.

[0053] Reference Figure 4 Optionally, the lotus leaf bionic semi-submersible photovoltaic support array structure further includes a second anchor block and a second anchor chain, the second anchor block being connected with the end of the support rod 20 of the lotus leaf bionic semi-submersible photovoltaic support away from the photovoltaic panel support assembly through the second anchor chain. One second anchor block can be connected with multiple lotus leaf bionic semi-submersible photovoltaic supports through the second anchor chain, which can enable multiple lotus leaf bionic semi-submersible photovoltaic supports to share one second anchor block, so that it is not necessary to install a second anchor block for each lotus leaf bionic semi-submersible photovoltaic support during assembly, and the construction of the lotus leaf bionic semi-submersible photovoltaic support array structure is simpler. The second anchor block can also be provided in multiple, and one second anchor block can be connected with one lotus leaf bionic semi-submersible photovoltaic support through one second anchor chain; the connection positions of the multiple second anchor blocks with the lotus leaf bionic semi-submersible photovoltaic support array structure can be distributed at intervals in the circumferential direction of the lotus leaf bionic semi-submersible photovoltaic support array structure, so as to improve the effect of the limiting action of the second anchor block on the lotus leaf bionic semi-submersible photovoltaic support array structure.
