Description

A floating photovoltaic platform and photovoltaic power station Technical Field

[0001] This utility model relates to the field of floating photovoltaic platform technology, and in particular to a floating photovoltaic platform and a photovoltaic power station. Background Technology

[0002] With the increasing global demand for clean energy, offshore photovoltaic (PV) power generation, as a highly promising renewable energy utilization method, has gradually attracted widespread attention. The sea offers vast space, enabling the large-scale construction of PV power plants, and compared to terrestrial PV, superior sunlight conditions at sea can effectively improve PV power generation efficiency.

[0003] Existing technologies have certain problems. Some platform structures may sway, shift, or even be damaged under the influence of wind and waves on the water surface, thus affecting power generation efficiency and equipment lifespan. Some platforms are also poorly adaptable to different aquatic environments and perform poorly under varying water levels and flow conditions. Therefore, we urgently need a floating photovoltaic platform and photovoltaic power station to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of insufficient stability and poor environmental adaptability of existing floating photovoltaic platforms, and to propose a floating photovoltaic platform and photovoltaic power station.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A floating photovoltaic platform includes a fixed frame and photovoltaic panels installed on the fixed frame, and further includes: a support fixedly installed at the end of the fixed frame, a floating platform provided below the support, and the support and the floating platform being connected by a support part; multiple sets of independent watertight compartments opened in the floating platform, the bottom of the floating platform having a flow guide channel, and the flow guide channel being distributed crisscrossingly along the bottom of the floating platform; and a wave-resistant part fixedly installed on the floating platform.

[0007] To reduce water flow interference, preferably, the wave-resistant part includes an opening frame fixedly installed on the four sides of the floating platform. Multiple sets of wave-resistant fins for reducing water flow interference are fixedly connected inside the opening frame, and the multiple sets of wave-resistant fins are arranged in a linear array.

[0008] To ensure the stability of the floating platform, the anti-wave fin has a triangular cross-section, with a sharp frontal surface and an arc-shaped back surface.

[0009] For ease of installation, preferably, the support includes connecting rods fixedly connected to the four corners of the bottom of the bracket. The connecting rods have circular insertion holes, and damping pads are fixedly connected inside the circular insertion holes. The floating platform is fixedly connected to a plug for fitting the connecting rods. When the plug is inserted into the circular insertion hole, a limiting zone is formed.

[0010] To improve installation stability, a limiting ring is further threaded onto the insertion rod, and a threaded protrusion adapted to the limiting ring is provided on the connecting rod. When the insertion rod is inserted into the circular insertion hole, the limiting ring and the threaded protrusion are threadedly connected to form a limiting area.

[0011] To allow for the expansion of the photovoltaic platform, preferably, the bracket is symmetrically equipped with hinged fasteners for expansion.

[0012] A photovoltaic power station includes a floating photovoltaic platform.

[0013] Compared with the prior art, this utility model provides a floating photovoltaic platform and photovoltaic power station, which has the following beneficial effects:

[0014] 1. This floating photovoltaic platform, through the installation of anti-wave fins, can change the direction of wave impact to the greatest extent, converting the horizontal impact force of the waves into part of the vertical force, and using the buoyancy of the floating body itself to offset part of the wave force, thereby effectively reducing the horizontal swaying amplitude of the platform.

[0015] 2. This floating photovoltaic platform, through the setting of water-proof chambers and diversion channels, can effectively prevent the floating platform from sinking due to damage to a certain part, thereby improving the safety and reliability of the floating platform. In addition, the crisscrossing diversion channels can effectively reduce the impact of water flow on the floating body and enhance the stability of the platform in the water flow.

[0016] 3. This floating photovoltaic platform, through the setting of the support unit, allows operators to align the connecting rod on the bracket with the insertion position on the floating platform and insert it. When the bracket and the floating platform are combined, the limiting ring can be rotated upward to cover the connection point, thereby completing the fixing effect. The operator can then install the photovoltaic panels on the fixed frame and adjust the angle, thus effectively achieving a fast installation speed for the bracket and the floating platform. It also allows for easy adjustment of the connection height between the bracket and the floating platform according to different water conditions, improving the photovoltaic platform's adaptability to the environment.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention improves the stability of the floating photovoltaic platform and addresses the previous issue of poor environmental adaptability of floating photovoltaic platforms.

[0026] Referring to Figures 1-5, a floating photovoltaic platform includes a fixed frame 1 and photovoltaic panels 2 mounted on the fixed frame 1. It also includes a bracket 3 fixedly mounted at the end of the fixed frame 1, with hinged fasteners 15 symmetrically mounted on the bracket 3 for expansion. A floating platform 4 made of high-density polyethylene is disposed below the bracket 3. The bracket 3 and the floating platform 4 are connected by a support portion, which includes connecting rods 9 fixedly connected to the four corners of the bottom of the bracket 3. Circular insertion holes 10 are provided on the connecting rods 9, and damping pads 11 are fixedly connected inside the circular insertion holes 10. Insertion rods 12 for adapting to the connecting rods 9 are fixedly connected to the floating platform 4. When the insertion rod 12 is inserted into the circular insertion hole 10, a limiting area is formed. A limiting ring 13 is threadedly connected to the insertion rod 12. The support 9 is provided with a threaded protrusion 14 that is adapted to the limiting ring 13. When the insertion rod 12 is inserted into the circular insertion hole 10, the limiting ring 13 and the threaded protrusion 14 are threadedly connected to form a limiting area. Here, the operator can align the connecting rod 9 on the support 3 with the insertion rod 12 on the floating platform 4 and insert it. When the support 3 and the floating platform 4 are combined, the limiting ring 13 can be rotated upward to cover the connection and thus complete the fixing effect. The operator can then install the photovoltaic panel 2 on the fixing frame 1 and adjust the angle, thereby effectively realizing the rapid installation speed of the support 3 and the floating platform 4. The connection height between the support 3 and the floating platform 4 can be easily adjusted according to different water conditions, improving the adaptability of the photovoltaic platform to the environment.

[0027] Multiple independent watertight chambers 5 are set inside the floating platform 4. The bottom of the floating platform 4 is provided with a flow channel 6, which is distributed in a crisscross pattern along the bottom of the floating platform 4. Here, the watertight chambers 5 can effectively prevent the whole body from sinking due to damage to a certain part, improve the safety and reliability of the floating platform 4, and, together with the crisscross flow channel 6, can effectively reduce the impact of water flow on the floating body and enhance the stability of the platform in the water flow.

[0028] The wave-resistant component is fixedly installed on the floating platform 4. The wave-resistant component includes opening frames 7 fixedly installed on the four sides of the floating platform 4. Multiple sets of wave-resistant fins 8 for reducing water flow interference are fixedly connected within the opening frames 7. These wave-resistant fins 8 are arranged in a linear array. The cross-section of each wave-resistant fin 8 is triangular, with a sharp wave-facing surface and an arc-shaped back surface. Here, when waves impact the floating platform 4, the sharp wave-facing surface can cut into the wave first, dispersing the impact force and reducing direct impact on the platform. The back surface helps guide the dispersed wave flow along the fins. The smooth surface of the water flow reduces turbulence interference on the platform, further ensuring its stability in waves. It is important to note that one end of the wave-resistant fin 8 is fixedly connected to the inner wall of the open frame 7, while the other end extends away from the float, forming an angle of 45°-60° with the inner wall of the open frame 7. Within this angle range, the wave-resistant fin 8 can maximally alter the direction of wave impact, converting the horizontal impact force of the waves into a portion of the vertical force. The buoyancy of the float itself counteracts some of the wave force, effectively reducing the platform's horizontal sway. Example

[0029] Referring to Figures 1-5, based on Example 1, multiple floating photovoltaic platforms form a photovoltaic power station for large-scale power generation operations.

[0030] In this invention, the operator aligns the connecting rod 9 on the bracket 3 with the insertion rod 12 on the floating platform 4 at the shore, then moves the bracket 3 downward so that the insertion rod 12 is inserted into the circular insertion hole 10. The damping pad 11 causes the bracket 3 to move downward slowly. When it reaches the required height, the four limiting rings 13 are rotated upward so that they engage with the threaded protrusion 14 on the connecting rod 9, thus completing the installation process of the bracket 3 and the floating platform 4. At this point, the photovoltaic panel 2 is installed on the fixed frame 1 to complete the installation of the photovoltaic platform. The entire photovoltaic platform is then moved into the water. When the waves impact the floating platform 4, the wave-resistant fin 8 can change the direction of the wave impact, converting the horizontal impact force of the waves into a partial vertical force. The buoyancy of the float itself is used to offset part of the wave force, thereby effectively reducing the horizontal swaying amplitude of the platform. When it is necessary to expand the photovoltaic platform, another set of photovoltaic platforms can be hinged to the hinge buckle 15 to achieve the expansion of the photovoltaic platform.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
