DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0029] The "top surface" is referenced based on the normal use state of the photovoltaic support device for water surface and its assembly structure with the photovoltaic module. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0030] In addition, terms such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more such features. In the description of the creation of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more than two.

[0031] As Figures 1 - 6 shown, a photovoltaic supporting device for water surface of the present utility model includes a supporting member 1 and an inclination angle adjusting member 3. The supporting member 1 is provided with a supporting plane 11 and a convex portion 10 surrounded by a curved surface. The inclination angle adjusting member 3 is used to adjust the supporting plane 11 to be in a horizontal state or an inclined state; the inner cavity of the convex portion 10 includes a light layer (not shown) and a center of gravity adjusting layer (not shown) stacked in sequence along the convex direction.

[0032] Figure 2 shown, the convex portion 10 of the supporting member 1 is set as a curved surface, which is beneficial to dispersing the force when the water wave impacts the surface of the supporting member, and improving the durability and strength of the supporting member. In order to simplify the structure of the supporting member, further, the supporting member is spherical. Further, the light layer can be one of inert gas, polyurethane foam (PU), epoxy resin foam or polyetherimide (PEI) foam. Among them, the inert gas includes but is not limited to nitrogen, carbon dioxide, helium, etc.; the polyurethane foam has good chemical resistance and physical properties, including relatively high compressive strength and shear strength, and good water resistance and corrosion resistance, and is suitable for water body environments such as the ocean. The epoxy resin foam is famous for its excellent mechanical properties and chemical stability, such as high rigidity and dimensional stability, as well as resistance to seawater. The PEI foam has excellent chemical resistance and thermal stability, has good resistance to seawater, and at the same time maintains good mechanical strength. The material of the center of gravity adjusting layer is sand. Among them, quartz sand containing silicon dioxide has relatively high hardness and chemical stability and is not easy to weather. The sand is arranged at the bottom of the supporting member to increase the weight of the bottom of the supporting member, thereby lowering the overall center of gravity. The lower the center of gravity, the more stable the supporting member is and the less likely it is to tip over. Further, the outer shell material of the supporting member is ethylene-vinyl acetate copolymer (EVA). The EVA material has good softness and elasticity, generates a buffering force when the water wave impacts the surface of the supporting member, and reduces the probability of damage; it also has good aging resistance, can resist the erosion of ultraviolet rays, ozone and general chemicals; it also has low temperature resistance, and can still maintain its flexibility and elasticity at low temperatures, and is suitable for applications in cold environments; it is an environmentally friendly material, non-toxic and odorless; it is easy to process and form; it also has biodegradability, reducing the impact on the environment.

[0033] In order to connect multiple supporting members in series, thereby installing more photovoltaic modules while maintaining the stability of the overall device. Therefore, it further includes a strengthening base 2 for connecting the supporting members 1 in series. The strengthening base 2 includes at least one side support member 20 and at least one connecting rod 21. The connecting rod 21 includes a first end and a second end. The first end is fixedly connected to the side support member 20, and the second end extends along a first direction and passes through the lightweight layer of the supporting member 1. The supporting member 1 is rotatably connected to the connecting rod 21, and the connecting rod 21 is provided with a limiting member (not marked) for fixing the axial movement of the supporting member 1.

[0034] The outer contour of the supporting member 1 is spherical, so the extending direction of the second end of the connecting rod 21 is the same as the radial extending direction of the supporting member 1, ensuring the balance of the supporting member 1 in the static state and improving the stability of the device.

[0035] In some embodiments, there is one connecting rod 21, and several supporting members 1 are connected in series on the connecting rod 21. At least one end of the connecting rod 21 is fixedly connected to the side support member 20.

[0036] In some other embodiments, there are more than two connecting rods 21, and several supporting members 1 are connected in series on any one of the connecting rods 21. The number of supporting members 1 connected in series on each connecting rod 21 can be the same or different. In order to flexibly and uniformly adjust the horizontal or inclined state between the supporting members 1 and expand the spreading area of the device, the number of supporting members 1 connected in series on each connecting rod 21 is the same and they are arranged side by side along the arrangement direction of the connecting rod 21.

[0037] Such as Figure 1 、 5 As shown in 6, in some preferred embodiments, in order to enhance the support stability and strength, the side support members 20 are arranged in pairs and relatively, and there are several connecting rods 21; several connecting rods 21 are arranged side by side along a second direction perpendicular to the first direction and are all clamped between the paired side support members 20. Further, the side support member 20 is provided with an inclined top surface 22 for setting the photovoltaic module, and facing south is beneficial to absorb more sunlight. Furthermore, the side support member 20 is a pipe column extending along the second direction or a hemispherical shell arranged along the second direction. The pipe column side support member has greater mechanical strength, while for the side support member of the hemispherical shell, the force will be dispersed after being impacted by water waves in any direction on its surface, thereby reducing the damage caused by the impact. The bottom of the side support member 20 is provided with a hook ear (not marked) for hanging the towing rope to prevent the device from floating away with the water flow.

[0038] For a single supporting member 1 provided, or in order to separately control the inclination angle of the supporting member 1, further, the inclination angle adjusting member 3 includes a pair of first gravity adjusting members arranged in pairs, and the pair of first gravity adjusting members are respectively arranged on both sides of the supporting member 1 along the axial direction of the connecting rod 21.

[0039] Such asFigure 1 and 3 As shown in 3 , in some preferred embodiments, in order to flexibly adjust the tilt angle of the support member and improve the adjustment efficiency, the tilt angle adjustment member 3 includes a pair of second gravity adjustment members 30 and a balance rod assembly 31. The support members 1 arranged along the second direction have a head support member (not labeled) and a tail support member (not labeled). The pair of second gravity adjustment members 30 are respectively connected to the outer ends of the head support member and the tail support member through a first rotating shaft (not labeled); the balance rod assembly 31 is clamped between the head support member and the tail support member and is connected to the adjacent support members 1 through a second rotating shaft (not labeled).

Further, the balance rod assembly 31 includes a pair of side rods 311, a cross rod 312, and a core shaft 313.

Both ends of the cross rod 312 are respectively connected to the pair of side rods 311 through a third rotating shaft; the extending direction of the core shaft 313 and the third rotating shaft are both consistent with the first direction. The extending end of the core shaft 313 is fixedly connected to the side support member 30. The core shaft 313 passes through the cross rod 312 and is rotatably connected thereto.

[0040] The first gravity adjustment member or the second gravity adjustment member includes a storage box body, a water pump, and a controller. The water pump is communicated with the inner cavity of the storage box body and is communicatively connected to the controller. The water pump adjusts the weight of the storage box body under the action of the controller.
