Description

Technical Field

[0001] The invention belongs to the technical field of offshore photovoltaics and relates to an offshore photovoltaic platform made of bamboo-based materials. Background Art

[0002] Offshore photovoltaic platforms refer to solar power generation systems installed in the ocean. They use floating structures to deploy photovoltaic panels on the water surface or offshore areas to capture sunlight and convert it into electricity. This innovative technology can not only make full use of unoccupied water resources, but also reduce water evaporation and inhibit algae growth to a certain extent, with multiple environmental benefits.

[0003] The overall structure of existing photovoltaic platforms is usually supported by steel structures, which extend into the sea to provide stability. However, such steel structures will be corroded by seawater during long-term use, causing structural damage to the photovoltaic platform. In addition, the steel structure material itself is heavy and used in large quantities, so the installation cost is high. More importantly, once the surface of the steel structure begins to corrode, the stability of the platform will be reduced under the continuous impact of seawater, and may even cause the structure to fall apart. In addition, corrosive substances may also cause certain pollution risks to the seawater environment. Summary of the invention

[0004] In view of this, the present invention provides a bamboo-based material offshore photovoltaic platform.

[0005] Technical solution: An offshore photovoltaic platform made of bamboo-based materials includes a vertical connecting column, a horizontal connecting bottom column, a horizontal connecting top column, a connecting flange, a photovoltaic panel, a floating box, a connecting steel cable and a fastening lock.

A plurality of seabed foundation piles are arranged and evenly spaced and installed on the seabed along the circumferential direction. The tail end of the connecting steel rope is connected to the seabed foundation pile.

[0007] In one of the embodiments, it also includes a sunlight tracking mechanism, which includes a waterproof motor, a driving gear, a controller and a sunlight tracker. Waterproof motors are installed at the bottom of the connecting flanges located at the four corners below. The output shaft of the waterproof motor is connected to the driving gear. The floating ring is provided with teeth at evenly spaced intervals, and the driving gear is meshed with the teeth. A controller is installed on one of the horizontal connecting top columns, and a sunlight tracker is installed on the photovoltaic panel. The waterproof motor and the sunlight tracker are both electrically connected to the controller.

[0008] In one of the embodiments, a straightening mechanism is also included, and the straightening mechanism includes a gravity ring, a mounting frame and a pulling guide wheel. The gravity ring is evenly spaced with mounting frames whose number is the same as the number of connecting steel ropes, and each mounting frame is equipped with two pulling guide wheels. The two pulling guide wheels are respectively located on both sides of the connecting steel rope to pull the connecting steel rope.

[0009] In one of the embodiments, a connecting mechanism is also included, which includes a cross-type connecting column, a connecting buckle and a connecting ring. A connecting ring is connected to the middle of each vertical connecting column, and every two adjacent diagonal connecting rings are connected by a cross-type connecting column.

[0012] In one embodiment, the vertical connecting columns, the horizontal connecting bottom columns, the horizontal connecting top columns and the cross connecting columns are all bamboo-based composite tubes.

[0013] In one of the embodiments, it also includes lifting ears, and the connecting flanges located at the lower edge of the frame are equipped with lifting ears.

[0014] The present invention has the following advantages: 1. During use, the present invention adopts bamboo-based pipes to replace traditional steel pipes to construct a photovoltaic platform. Since the density of bamboo is only one-seventh of that of steel, the weight and construction cost of the entire photovoltaic platform are reduced; in addition, the surface of the bamboo-based pipe is made of bamboo material, which can significantly reduce the corrosion of seawater to the structure, thereby extending the service life of the platform.

[0030] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Bamboo-based offshore photovoltaic platforms, such as Figure 1-Figure 5 As shown, it includes a vertical connection column 1, a horizontal connection bottom column 2, a horizontal connection top column 3, a connection flange 4, a photovoltaic panel 5, a floating box 6, a connection cable 71 and a fastening lock 72. The vertical connection columns 1 are provided with sixteen, and are evenly spaced in the horizontal and vertical directions, with four in each row and column. The top and bottom of the vertical connection columns 1 are connected with a connection flange 4. The horizontal connection bottom column 2 is connected between the connection flanges 4 at the bottom of every two adjacent vertical connection columns 1. The horizontal connection top column 3 is connected between the connection flanges 4 at the top of every two adjacent vertical connection columns 1. A photovoltaic panel 5 is installed on the top column 3, and a plurality of horizontally connected bottom columns 2 form a criss-cross frame structure. A floating box 6 is installed in each space of the frame. The buoyancy of the floating box 6 facilitates the floating of the entire photovoltaic platform. Connecting steel cables 71 are arranged inside the vertical connecting columns 1, the horizontally connected bottom columns 2 and the horizontally connected top columns 3. Adjacent connecting steel cables 71 are connected by fastening buckles 72, so that the plurality of connecting steel cables 71 form a grid structure to form a steel cable grid. The stability between the vertical connecting columns 1, the horizontally connected bottom columns 2 and the horizontally connected top columns 3 is increased by the steel cable grid.

[0032] The photovoltaic platform is composed of vertical connecting columns 1, horizontal connecting bottom columns 2 and horizontal connecting top columns 3 made of bamboo-based composite pipes to form the frame of the photovoltaic platform, and a steel cable grid composed of connecting steel cables 71 and fastening lock buckles 72 is used as an inner lining. The ends of the bamboo-based composite pipes are provided with connecting flanges 4. All pipes are connected by flange structures, and the pipes are interconnected. The steel cable grid structure formed inside the pipes enables the pipes to be interconnected, thereby increasing the stability of the entire photovoltaic platform frame. Even if some pipes are damaged, the frame can be connected and supported by the steel cable grid to prevent the damaged steel pipes from falling apart under the impact of seawater.

[0033] like Figure 6As shown, it also includes a limiting mechanism, which includes a floating ring 81, a seabed foundation pile 82 and a connecting steel rope 83. A plurality of connecting steel ropes 83 are evenly spaced and connected to the bottom of the floating ring 81. A plurality of seabed foundation piles 82 are arranged and evenly spaced along the circumferential direction and installed on the seabed. The tail end of the connecting steel rope 83 is connected to the seabed foundation pile 82.

[0034] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes a sunlight tracking mechanism, which includes a waterproof motor 84, a driving gear 85, a controller 86 and a sunlight tracker 87. Waterproof motors 84 are installed at the bottom of the connecting flanges 4 located at the four corners below. The output shaft of the waterproof motor 84 is connected to the driving gear 85. The floating ring 81 is evenly spaced with teeth and grooves, and the driving gear 85 is engaged with the teeth and grooves. A controller 86 is installed on one of the horizontal connecting top columns 3, and a sunlight tracker 87 is installed on the photovoltaic panel 5. The waterproof motor 84 and the sunlight tracker 87 are both electrically connected to the controller 86.

[0035] When using the photovoltaic platform, the connecting steel rope 83 and the floating ring 81 are connected to the seabed pile 82, and the floating ring 81 is fixed in a rough area by the seabed pile 82. The frame composed of the vertical connecting column 1, the horizontal connecting bottom column 2 and the horizontal connecting top column 3 is meshed with the floating ring 81 through the driving gear 85, so that the entire frame is also confined in the floating ring 81, and the position of the entire photovoltaic platform is limited to prevent the photovoltaic platform from floating randomly. During use, the direction of sunlight can be tracked by the sunlight tracker 87, and a signal is sent to the controller 86, so that the controller 86 controls the waterproof motor 84 to start. The waterproof motor 84 is started When the photovoltaic panel 5 is moved, the driving gear 85 is driven to rotate. At this time, since the floating ring 81 does not rotate, the driving gear 85 can rotate along the floating ring 81 when rotating, thereby driving the frame composed of the vertical connecting column 1, the horizontal connecting bottom column 2 and the horizontal connecting top column 3 to rotate together, thereby changing the direction of the photovoltaic panel 5, so that the photovoltaic panel 5 faces the sunlight, ensuring the power generation effect of the photovoltaic panel 5, and when installing the photovoltaic platform, the entire platform frame is in a semi-floating state, and the upper half of the vertical connecting column 1 is exposed to the sea surface sponge. When the waves hit, the vertical connecting column 1 will disperse the waves to avoid concentrated force, so as to prevent the wave hammer effect, and the dispersed bracket will not concentrate the force of the waves. Preferably, the two ends of the photovoltaic panel 5 are respectively installed on the horizontal connecting top column 3 through a fixed bracket and a telescopic bracket, wherein the telescopic bracket is in an extended state, and its height is greater than the height of the fixed bracket, and the telescopic bracket is in a retracted state, and its height is equal to the height of the fixed bracket. In normal working state, the telescopic bracket is in an extended state, so that the photovoltaic panel 5 is tilted to better receive sunlight, and when there is a typhoon, the telescopic bracket is retracted, so that the photovoltaic panel 5 is in a flat state to avoid being damaged by too much wind. The telescopic bracket in this embodiment can adopt an existing scissor-type telescopic structure, which will not be described here.

[0036] like Figure 6 , Figure 8 and Fig. 9 As shown, it also includes a straightening mechanism, which includes a gravity ring 91, a mounting frame 92 and a pulling guide wheel 93. The gravity ring 91 is evenly spaced with mounting frames 92 whose number is the same as the number of connecting steel ropes 83, and each mounting frame 92 is installed with two pulling guide wheels 93. The two pulling guide wheels 93 are respectively located on both sides of the connecting steel rope 83 to pull the connecting steel rope 83.

[0037] During the use of the photovoltaic platform, as the sea level changes with the ebb and flow of the tide, the floating ring 81 will also move up and down. After the photovoltaic panel 5 moves downward, the connecting steel rope 83 will loosen. At this time, the gravity ring 91 sinks under the action of gravity, which can drive the mounting frame 92 and the pulling guide wheel 93 to move downward. The pulling guide wheel 93 will pull the connecting steel rope 83 during the downward movement, so that the connecting steel rope 83 is tightened from the pulling guide wheel 93 to the floating ring 81, thereby preventing the floating ring 81 from floating around after the connecting steel rope 83 is loosened.

[0038] like Fig.10 As shown, a connecting mechanism is also included, which includes a cross-type connecting column 101, a connecting buckle 102 and a connecting ring 103. A connecting ring 103 is connected to the middle of each vertical connecting column 1, and every two adjacent diagonal connecting rings 103 are connected through a cross-type connecting column 101. A connecting buckle 102 is connected between the staggered positions of two cross-type connecting columns 101. The cross-type connecting column 101 is fixed by the connecting buckle 102, and is connected to the frame of the entire photovoltaic platform through the cross-type connecting column 101, so as to increase the structural strength of the entire photovoltaic platform, thereby improving the stability of the entire photovoltaic platform during use.

[0039] like Fig.11 As shown, a signal light 11 is also included. The upper connecting flange 4 is equipped with a signal light 11. The signal light 11 can remind surrounding ships of the platform's location, making it easier for passing ships to find the photovoltaic platform and approach for power supply.

[0040] like Fig.12 As shown, a sensing probe 12 is also included. The sensing probe 12 is installed at the bottom of the connecting flange 4 below, and can sense whether water has entered the pipe of the frame structure.

[0041] The vertical connecting column 1, the horizontal connecting bottom column 2, the horizontal connecting top column 3 and the cross connecting column 101 are all bamboo-based composite pipes, which are mainly formed into bamboo strips through carbonization, drying, and immersion of bamboo strips in glue. The bamboo strips are then surface-dried and spliced ​​into bamboo boards. The tightness between the bamboo strips is increased through high temperature and high pressure, and the bamboo boards are then planed into bamboo skins. After the processing is completed, the bamboo skins are wrapped around the stainless steel lining to form a pipeline product.

[0042] like Fig.12 As shown, it also includes a lifting lug 13, and the connecting flange 4 located at the edge of the frame below is equipped with a lifting lug 13. The ship can lift the entire photovoltaic platform at the stern of the ship through the lifting lug 13, and tow the photovoltaic platform by moving the ship to facilitate the movement of the photovoltaic platform.

[0043] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
