Description

Technical Field

[0001] The invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to a floating offshore photovoltaic fishery integrated system. Background Art

[0002] As a clean, pollution-free and easily available renewable energy, solar energy is becoming more and more popular. Solar photovoltaic power generation platforms have the advantages of no noise, no pollution, short construction period, safety and reliability. They have been widely used in recent years and are of great significance to alleviating energy shortages and reducing environmental pollution.

[0003] Solar photovoltaic power generation is based on the photovoltaic effect, using solar cells to convert solar energy into electrical energy. Solar photovoltaic power generation platforms are mainly composed of solar panel components, controllers and inverters. According to the relationship between the system and the power grid, they can be divided into grid-connected and off-grid photovoltaic power generation platforms. Although solar photovoltaic power generation has many advantages, it also has some disadvantages, such as high one-time investment costs and large land occupation of solar cell components. With the substantial growth of the world's population, problems such as lack of land resources are becoming increasingly serious.

[0004] Solar photovoltaic power generation often occupies a large amount of land due to the large site area required, while the available land area is very limited.

[0005] Existing photovoltaic systems are still limited to land. There are photovoltaic projects built on the water, and the sites are often selected in shallow waters such as ponds and lakes. They have not yet been used on a large scale in the near sea and offshore. Due to the harsh environment in which they are located, the cost of offshore photovoltaic platforms is relatively high. If the platform is designed with power generation as the sole goal, the overall benefits are not high. In large-scale deployment, multiple power generation platforms must be spliced ​​into an overall power generation system. How to ensure the stability of the overall power generation system when there are large waves at sea and how to ensure that the power generation platforms are still tightly connected is a design challenge. Existing offshore photovoltaic power generation platforms are often developed and designed for single units, and lack connection designs between platforms. Summary of the invention

[0039] like Figure 1 and 2 As shown, the present invention discloses a floating offshore photovoltaic fishery integrated system, which is divided into a photovoltaic power generation platform 1 and a fishery breeding platform, and the photovoltaic power generation platform 1 is arranged in a matrix; Figure 1 As shown, in the longitudinal direction, the photovoltaic power generation platforms 1 are connected in series in sequence; in the transverse direction, a fishery breeding platform is hung between two adjacent photovoltaic power generation platforms 1.

[0040] like Figure 2 As shown, the fishery breeding platform includes a traction cable 4, a hanging net 5 and a plurality of buoys 3, and the plurality of buoys 3 are connected in series; Figure 3As shown, the photovoltaic power generation platform 1 includes an upper frame 11 and a lower frame 12, the upper frame 11 is provided with a plurality of upper anchoring points 15, and the lower frame 12 is provided with a plurality of lower anchoring points 16; one end of the traction cable 4 is connected to the pile foundation 2, and the other end is connected to the lower anchoring point 16; one side of the serially connected floating body 3 is connected to the upper anchoring point 15 of one of the photovoltaic power generation platforms 1, and the other side of the floating body 3 is connected to the upper anchoring point 15 of another photovoltaic power generation platform 1; a hook 191 is provided on the hanging net 5, which is respectively hung with the upper anchoring point 15, the traction cable 4 and the floating body 3.

[0041] The pile foundation 2 is fixed on the seabed and is a steel pipe pile foundation 2 that has been treated with anti-corrosion and is arranged along the seabed around the photovoltaic power generation platform 1 .

[0042] The traction cable 4 is a stainless steel cable, which connects the pile foundation 2 and the lower anchor point 16 of the photovoltaic power generation platform 1 to ensure that the photovoltaic power generation platform 1 is fixed as a whole.

[0043] like Figure 3 As shown, the photovoltaic power generation platform 1 includes an upper frame 11 located above the water surface and a lower frame 12 located below the water surface, and the upper frame 11 and the lower frame 12 are connected by a column 13;

[0044] A buoy 14, wherein the buoy 14 is fixedly connected to the lower frame 12;

[0045] A support frame 110, wherein the support frame 110 is arranged in the transverse direction of the platform frame, and the support frame 110 is arranged on the upper frame 11;

[0046] A photovoltaic panel 111, wherein the photovoltaic panel 111 is fixedly connected to the support frame 110;

[0047] The platform docking hanger 19 is fixedly connected to one side of the upper frame 11 and the lower frame 12 .

[0048] Preferably, the photovoltaic power generation platform 1 also includes an operation and maintenance channel 18, which is convenient for photovoltaic operation and maintenance personnel to inspect and operate the platform. The operation and maintenance channel 18 is composed of a steel plate located between two adjacent support frames 110 on the upper frame 11, and the steel plate is fixed to the support frame 110 by bolts, and the steel plate is evenly distributed along the lateral direction of the support frame 110.

[0049] Specifically, the upper frame 11 and the lower frame 12 are rectangular steel frame structures formed by welding anti-corrosion steel pipes.

[0050] The pontoon 14 is a cylindrical thin-wall reinforced concrete pontoon. The busbar of the pontoon 14 is parallel to the steel pipe of the lower frame 12 . The pontoon 14 and the steel pipe of the lower frame 12 are cast as one body.

[0051] A plurality of support rails 17 are fixedly connected to the upper frame 11 , and guide grooves are formed on the support rails 17 . A support frame 110 for supporting the photovoltaic panel 111 is installed on the support rails 17 . The lower part of the support frame 110 is embedded in the guide groove for movement in the guide groove.

[0052] The support rail 17 is a C-shaped channel steel, and the support frame 110 includes two symmetrically arranged triangular supports, and two cross bars 1102 are fixed on the inclined surface formed by the two triangular supports; the lower part of the triangular supports is connected to a connecting plate 1101, and a roller is provided at the lower part of the connecting plate 1101.

[0053] Preferably, a platform docking hanger 19 is connected to one side of the upper frame 11 and the lower frame 12, such as Figure 4 As shown, the platform docking hanger 19 includes a connecting block 195, a buffer mechanism 193 and a hook 191. The connecting block 195 is connected to the upper frame and the lower frame 12. A universal joint 194 is embedded in the connecting block 195. One end of the buffer mechanism 193 is connected to the universal joint 194, and the other end is connected to the hook 191. The universal joint 194 can move the hook 191 in the X, Y, and Z axes to ensure that the photovoltaic power generation platform 1 can still move in the waves and the hook 191 will not fall off.

[0054] A latch hole 192 is provided at one end of the buffer mechanism 193 connected to the hook 191.

The hook 191 is not limited to the James hook 191 and other common hooks used in trains in the railway system.

[0055] The buffer mechanism 193 is used to buffer the force transmitted axially by the hook 191 when two photovoltaic power generation platforms 1 are spliced ​​together. The buffer structure is used to mitigate the impact and vibration caused by the change in the relative position of the platforms. The buffer has the function of dissipating the impact and vibration between the platforms, thereby reducing the damage to the platform structure and the loaded cargo. The working principle of the buffer is to mitigate the impact force by means of compressing the elastic element, and at the same time absorb the impact energy by friction and damping during the deformation process of the elastic element.

[0056] The buffer structure can use a friction buffer, with a spiral spring at the front and inner and outer ring springs at the rear, which match each other with conical surfaces. When the buffer structure is compressed, the rings squeeze each other, and most of the impact energy is stored in the outer ring spring; at the same time, the inclined surfaces of the inner and outer ring springs rub against each other, converting part of the impact energy into heat energy. When the external force is removed, friction is generated between the ring springs, and part of the stored energy is once again converted into frictional heat energy and dissipated, thus playing a role in buffering and vibration reduction.

[0057] The floating body 3 is a high-density polyethylene buoy. Several floating bodies 3 are strung together and connected to the upper anchor point 15 by ropes. The floating bodies 3 can be used as cable channels between photovoltaic power generation platforms 1. There are hooks 191 on both sides of the floating body 3 for fixing the hanging net 5. The hanging net 5 is woven with nylon mesh wire or high-density polyethylene cable. There are hooks 191 on the hanging net 5, which are hung on the upper anchor point 15, the traction cable 4, and the floating body 3 respectively.

[0058] like Figure 1 As shown, the photovoltaic power generation platform 1 forms a matrix at sea. The photovoltaic power generation platform 1 is connected with the platform docking hook 191 in the longitudinal direction and connected with the floating body 3 in the transverse direction. The photovoltaic power generation platform 1 forms a fishery breeding platform in the longitudinal interval to breed fish, kelp, shellfish and other related marine products.
