Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a floating support device for a water surface photovoltaic module. Background Technology

[0002] With the ever-growing global demand for clean energy, solar energy, as an important renewable energy source, has received widespread attention. Especially in situations with limited land resources, floating photovoltaic (PV) modules are gradually becoming an ideal solution due to their ability to effectively utilize large areas of water for solar power generation. Floating PV systems use floating support devices to fix solar panels on the water surface, which not only improves power generation efficiency but also conserves valuable land resources.

[0003] However, current floating photovoltaic systems still have shortcomings when facing extreme weather conditions such as strong winds and waves. Specifically, the buoyancy portion of the floating support device that contacts the water surface is of a fixed size and cannot be expanded or adjusted according to actual needs. This means that when encountering large waves, the fixed buoyancy is insufficient to cope with the increased turbulence forces, easily causing the entire floating device to capsize, thereby affecting the normal operation and lifespan of the floating photovoltaic modules. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a floating support device for photovoltaic modules on the water surface, in order to address the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: a floating support device for water surface photovoltaic modules, comprising: A central plate with buoyancy plate assemblies on both sides; An extension component is rotatably connected to the outer side wall of the buoyancy plate assembly away from the center plate. It is symmetrically arranged about the center plate and can be rotated to be flush with the buoyancy plate assembly to extend the floating support surface of the buoyancy plate assembly. The drive component is located at the end of the center plate, and its output end is connected to the extension component for transmission. When the extension component is stored, it can drive the extension component to flip to the top of the buoyancy plate component. When the extension component is used, it can drive the extension component to flip to be on the same plane as the buoyancy plate component. The controller communicates with the drive components and is able to control the actions of the drive components.

[0006] By using the above-mentioned technical means, the drive component drives the expansion component to rotate, so that the expansion components on both sides of the center plate rotate to be flush with the buoyancy plate component, thereby expanding the area of ​​the floating support surface and increasing the buoyancy and stability of the overall device.

[0007] In some embodiments, the drive assembly includes a double-ended cylinder, positioning blocks, connecting rods, a toothed plate, and gears. The double-ended cylinder is communicatively connected to the controller and is installed at the top end of the center plate. The double-ended cylinder is connected to an air source assembly. Positioning blocks capable of limiting the movement are provided on both sides of the double-ended cylinder. Connecting rods are connected to the output ends of the double-ended cylinder. The double-ended cylinder can control the connecting rods to reciprocate along their own axial direction. A toothed plate is connected to the end of the connecting rod away from the double-ended cylinder. Gears are provided on the buoyancy plate assembly. The toothed plate and gears mesh with each other, so that the toothed plate drives the gears to rotate the extension assembly.

[0008] In some embodiments, a slider is connected to the end of a set of toothed plates near the double-ended cylinder, and a symmetrical groove is provided on the top of the center plate. The slider is slidably connected to the groove, so that the toothed plates are guided by the slider during movement.

[0009] In some embodiments, the top of the buoyancy plate assembly is rotatably provided with an anti-tipping component. When the extension component and the buoyancy plate assembly are on the same plane, the anti-tipping component can rotate to abut the top of the extension component to press the extension component.

[0010] In some embodiments, the anti-tumble assembly includes a fixed base, a rotating shaft, a double-ended motor, a convex plate, a reinforcing rod, and a clamping block. The double-ended motor is communicatively connected to the controller. A pair of fixed bases are installed on the top platform of the buoyancy plate assembly. A rotating shaft is rotatably connected inside the fixed base. The rotating shafts inside the fixed bases at both ends are correspondingly connected to the two ends of the double-ended motor. A convex plate is correspondingly connected to the rotating shaft. A clamping block facing the top plane of the extension assembly is connected to the convex plate. A group of clamping blocks on the same side of the center plate are connected by multiple reinforcing rods.

[0011] In some embodiments, the outer side wall of the buoyancy plate assembly is provided with a pair of mounting plates, and a rotating rod is rotatably mounted between the mounting plates via a bearing. The side wall of the rotating rod is connected to the extension assembly, and the end of the rotating rod is connected to the drive assembly. The rotating rod is driven by the drive assembly to drive the extension assembly to rotate.

[0012] In some embodiments, the extension assembly includes an extension plate connected to the outer wall of the rotating rod, and the wall surface of the extension plate in contact with the water surface is arc-shaped.

[0013] In some embodiments, a plurality of axially extending strip-shaped diversion blocks are spaced apart on the wall surface of the expansion plate in contact with the water surface.

[0014] The beneficial effects of this utility model are: 1. By incorporating an extension component on the buoyancy plate assembly and utilizing a drive component to allow it to rotate to be flush with the buoyancy plate assembly when needed, the buoyancy plate assembly and the extension component work together to expand the area of ​​the floating support surface, increasing the buoyancy and stability of the overall device. In the event of large waves, the increased buoyancy area provides additional buoyancy support, reducing the risk of capsizing due to turbulent forces and improving the stability of the surface photovoltaic system under adverse weather conditions.

[0021] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0022] Combination Figures 1 to 4 As shown, this embodiment is a floating support device for a photovoltaic module on a water surface, including a central plate 1, a buoyancy plate assembly 2, an extension assembly 3, a drive assembly, and a controller. The drive assembly and the controller are communicatively connected, as shown below. Figure 2As shown, the top of the central plate 1 is used to install photovoltaic modules. Buoyancy plate assemblies 2 are located on both sides of the central plate 1. Extension components 3 are rotatably connected to the outer side wall of the buoyancy plate assemblies 2 away from the central plate 1. The extension components 3 on both sides are symmetrically arranged about the central plate 1. The extension components 3 can rotate to the top of the buoyancy plate assemblies 2, or rotate to be flush with the buoyancy plate assemblies 2, to expand the floating support surface of the buoyancy plate assemblies 2. A drive assembly is located at one end of the top of the central plate 1. The output end of the drive assembly is connected to the extension components 3. The controller can control the movement of the drive assembly to further drive the extension components. When storing the extension components 3, the drive assembly can drive the extension components 3 to flip to the top of the buoyancy plate assemblies 2; when using the extension components 3, the drive assembly can drive the extension components 3 to flip to be on the same plane as the buoyancy plate assemblies 2.

[0023] In some implementation schemes, such as Figure 3 As shown, the outer side wall of the buoyancy plate assembly 2 is provided with a pair of mounting plates. A rotating rod 7 is rotatably mounted between the mounting plates via a bearing. An extension assembly 3 is connected to the side wall of the rotating rod 7. The end of the rotating rod 7 is connected to the drive assembly for transmission. The drive assembly drives the rotating rod 7 to rotate, and the rotating rod 7 drives the extension assembly 3 to flip.

[0024] Furthermore, in this embodiment, the extension component 3 includes an extension plate 9, which is fixedly connected to the outer wall of the rotating rod 7. When the extension plate 9 is flipped to be flush with the buoyancy plate component 2, the wall surface of the extension plate 9 in contact with the water surface is arc-shaped. The arc-shaped wall surface can reduce the impact of water waves and improve the stability of the device in the water.

[0025] The rotating rod 7 structure gives the extension plate 9 good rotational freedom, making it easy to deploy and retract.

[0026] Furthermore, multiple axially extending strip-shaped diversion blocks 18 are spaced apart on the wall surface of the extension plate 9 that contacts the water surface.

[0027] The strip-shaped diverter 18 can disperse the direction of water flow to a certain extent, reduce the formation of eddies, and reduce the amplitude of swaying, so that the supported water surface photovoltaic system can still maintain good attitude stability and buoyancy distribution uniformity under strong wind and waves.

[0028] In some implementation schemes, such as Figure 4As shown, the drive assembly includes a double-ended cylinder 4, a positioning block 17, a connecting rod 5, a toothed plate 6, and a gear 8. The double-ended cylinder 4 is communicatively connected to the controller and is installed at the top end of the center plate 1. The double-ended cylinder 4 is connected to an air source assembly. Positioning blocks 17 are provided on both sides of the double-ended cylinder 4 to limit its movement, thereby improving the stability of the double-ended cylinder 4 and reducing shaking. The output ends of the double-ended cylinder 4 are connected to the connecting rod 5, which can control the connecting rod 5 to reciprocate along its own axis. The end of the connecting rod 5 away from the double-ended cylinder 4 is connected to the toothed plate 6. The end of the rotating rod 7 near the double-ended cylinder 4 is fitted with a gear 8. The toothed plate 6 and the gear 8 mesh with each other, so that the toothed plate 6 drives the gear 8 to rotate the extension plate 9. In this embodiment, the air source assembly can supply air to the double-ended cylinder 4. The air source assembly adopts a conventional air source device (not shown in the figure).

[0029] Furthermore, a set of toothed plates 6 is connected to a slider 15 near the end of the double-ended cylinder 4. The top of the center plate 1 is provided with a symmetrical groove 16. The opening direction of the groove 16 is on the same axis as the movement direction of the toothed plate 6. The slider 15 is slidably connected to the groove 16, so that the toothed plate 6 is guided by the slider 15 during movement.

[0030] The cooperation between the slider 15 and the groove 16 provides guidance for the movement of the toothed plate 6, thereby reducing the risk of the toothed plate 6 deviating or jamming during movement and ensuring a smooth and stable transmission process.

[0031] In some implementations, the top of the buoyancy plate assembly 2 is rotatably provided with an anti-tipping component 10. When the extension plate 9 and the buoyancy plate assembly 2 are on the same plane, the anti-tipping component 10 can rotate to abut the top of the extension plate 9 and press the extension plate 9 down by its own weight.

[0032] Furthermore, the anti-tilting assembly 10 includes a fixed base 11, a rotating shaft, a double-ended motor, a protruding plate 12, a reinforcing rod 14, and a retaining block 13. The double-ended motor is connected to the controller. A pair of fixed bases 11 are installed on the top platform of the buoyancy plate assembly 2. A rotating shaft is rotatably connected inside the fixed base 11. The rotating shafts in the fixed bases at both ends are correspondingly connected to the two ends of the double-ended motor. The rotating shafts are correspondingly connected to the protruding plates 12. The protruding plates 12 are connected to retaining blocks 13 facing the top plane of the extension plate 9. A group of retaining blocks 13 on the same side of the center plate 1 are connected by multiple reinforcing rods 14.

[0033] In extreme weather conditions, the clamping block 13 physically presses down the extension assembly 3 to reduce the risk of it overturning due to wind and waves. The fixed base 11, rotating shaft, protruding plate 12, and clamping block 13 work together to form a lever structure above the rotating rod 7. Multiple clamping blocks 13 are connected together using a reinforcing rod 14 to distribute the clamping force more evenly, preventing single-point failure from causing the entire extension assembly 3 to overturn. Because the protruding plate 12 is located above the rotating rod 7, and the clamping block 13 is far from the rotating rod 7, the pressure point is far from the rotating rod 7, which serves as the axis of rotation. This increases the anti-overturning torque, ensuring that when external wind and waves attempt to lift the extension plate 9 upwards, the pressure exerted by the clamping block 13 must be overcome.

[0034] The implementation principle of a floating support device for photovoltaic modules on water surface is as follows: First, the double-ended cylinder 4 is activated. The output end of the double-ended cylinder 4 drives the connecting rods 5 at both ends to move outward synchronously. The connecting rods 5 drive the toothed plate 6 to move outward. Due to the meshing of the toothed plate 6 and the gear 8, the gear 8 drives the rotating rod 7 to rotate. The rotating rod 7 drives the corresponding extension plate 9 to flip until the bottom arc surface of the extension plate 9 contacts the water surface, thereby increasing the floating support surface and providing more buoyancy compared to the buoyancy plate assembly 2 in windy weather. When the extension assembly is in the retracted state, the extension plate 9 flips to a vertical position and will not continue to flip, in order to reduce the impact on the photovoltaic module on the central plate.

[0035] Then, the dual-end motor is started, which drives the rotating shafts at both ends to rotate. The rotating shafts cause the convex plate 12 to flip, and the convex plate 12 causes the clamping block 13 to flip, so that the clamping block 13 presses against the top of the extension plate 9, which can reduce the shaking of the extension plate 9 and reduce the risk of the extension plate 9 flipping upward to a certain extent, thereby improving the overall stability of the floating support device and ensuring that the photovoltaic system on the top can be used normally.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
