Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic technology, and particularly to a steel-plastic hybrid floating bracket system for floating photovoltaic power plants on water and an assembly method thereof. Background Art

[0002] A photovoltaic power station is a power generation system that utilizes solar energy and consists of electronic components such as crystalline silicon panels and inverters, and is connected to the power grid to transmit electricity to the power grid. In recent years, people have developed floating photovoltaic power stations, which are systems that use floating bodies to float photovoltaic modules on the water surface for power generation. The main difference between a floating photovoltaic power station on water and a land-based photovoltaic power station is that floating bodies, mooring, and anchoring systems are used to replace the ground piles and brackets of land-based photovoltaics to provide support for photovoltaic modules. The rear-end junction box, inverter equipment, transformer, and collector line are the same as or similar to those of land-based photovoltaic systems. A photovoltaic power station is established on the water surface to overcome the disadvantage of large land resource occupation of traditional photovoltaic power stations.

[0003] Chinese Patent with application number CN201510714282.6 discloses a floating photovoltaic bracket system for water, which includes more than two floating boxes, installation grooves, several connecting pieces, photovoltaic panels, and supporting rods. The two groups of floating boxes are connected by connecting pieces. Installation grooves are provided on the side or top of the floating boxes, and the installation grooves are connected to the supporting rods, and the photovoltaic panels are fixed on the top of the supporting rods. The above floating photovoltaic bracket system for water has the advantages of simple processing, easy operation, and convenient installation. However, the above floating photovoltaic bracket system for water is only applicable to lakes with relatively calm water surfaces. The sea with larger fluctuations is more likely to submerge the photovoltaic bracket system in the water, and the photovoltaic panels can only have a certain inclination angle through the height difference of the water surface. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel-plastic hybrid floating bracket system for floating photovoltaic power plants on water and an assembly method thereof to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A steel-plastic hybrid floating bracket system for floating photovoltaic power plants on water, including a limiting plate. A control component is arranged inside the limiting plate. A plurality of connecting pipes are arranged in an array at the bottom of the limiting plate. A plurality of buoyancy components are arranged at the bottom of the limiting plate and between two connecting pipes.

The connecting assembly includes a buoyancy cavity formed in the limit plate. The buoyancy cavity is respectively communicated with the air outlet holes, the connecting cavity and the buoyancy assembly.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. In the present invention, two photovoltaic panel mounting frames are connected by hinge pieces, and a support assembly is arranged on the side of the two photovoltaic panel mounting frames close to the limit plate. The driving assembly is used to push the support assemblies to approach or move away from each other, and cooperate with the elongation or shortening of the support assemblies on both sides to adjust the inclination angle of the photovoltaic panel body, so that the photovoltaic panel body is always perpendicular to the light, improving the efficiency of converting light energy into electrical energy.

[0012] 2. In the present invention, a driving assembly is arranged in the connecting cavity, and the connecting cavity is communicated with the buoyancy cavity through a pressure valve.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figure 1-7, the present invention provides a technical solution: a steel-plastic hybrid floating bracket system for floating photovoltaic power generation and an assembly method thereof, including a limit plate 1, a control component is arranged inside the limit plate 1, a plurality of connecting pipes 2 are arranged in an array at the bottom of the limit plate 1, the limit plate 1 and the connecting pipes 2 are connected by bolts, and a plurality of limit plates 1 are horizontally distributed on the connecting pipes 2, and a plurality of connecting pipes 2 are vertically distributed at the bottom of the limit plate 1. By connecting a plurality of limit plates 1 and connecting pipes 2 and fixing the limit plate 1 and the connecting pipes 2 with bolts, the connection strength between the limit plate 1 and the connecting pipes 2 is improved, effectively preventing the problem that the device cannot be used due to the device being damaged by excessive sea wave fluctuations.

[0027] A plurality of connecting cavities are arranged on the limit plate 1, and a driving component 9 is arranged inside the connecting cavities. The driving component 9 is used to control the sliding of the supporting component 4 on the connecting pipe 2.

[0028] A plurality of buoyancy components 3 are arranged at the bottom of the limit plate 1 and between two connecting pipes 2. A supporting component 4 is arranged on each connecting pipe 2. The supporting component 4 includes a sliding block 401, and the sliding block 401 is slidably connected to the connecting pipe 2. An expansion base 402 is arranged on each sliding block 401, a telescopic rod 403 is arranged inside the expansion base 402, a rotating column 404 is arranged on one side of the top of the telescopic rod 403. The photovoltaic panel assembly 5 includes a photovoltaic panel mounting frame 501. The two sides of one end of the photovoltaic panel mounting frame 501 close to the limit plate 1 are respectively movably connected to the rotating column 404. A photovoltaic panel body 502 is arranged inside the photovoltaic panel mounting frame 501. Each adjacent two photovoltaic panel mounting frames 501 are connected by a hinge 6.

[0029] First, by arranging a plurality of floating blocks 301 at the bottom of the limit plate 1 and between two connecting pipes 2, the device floats on the water surface by the buoyancy of the floating blocks 301, and the photovoltaic panel body 502 arranged on the limit plate 1 and the connecting pipes 2 converts light energy into electrical energy, effectively saving land resources. At the same time, by building a photovoltaic panel on the water, the evaporation of the lake water is reduced by the shielding of the photovoltaic panel, improving the environment.

[0030] Secondly, through the sliding block 401 and the telescopic rod 403 arranged on the connecting pipe 2, when it is necessary to convert light energy into electrical energy by the photovoltaic panel body 502, the telescopic rod 403 connected to the photovoltaic panel mounting frame 501 is controlled to extend or contract by the control component, so that a plurality of telescopic rods 403 close to the same side limit plate 1 extend and drive the photovoltaic mounting frame 8 to deflect upward, and at the same time, a plurality of telescopic rods 403 on the other side contract downward to drive the photovoltaic mounting frame 8 to deflect downward, so that the photovoltaic mounting frame 8 is inclined and installed on the limit plate 1 and the connecting pipe 2, improving the efficiency of converting light energy into electrical energy by the photovoltaic panel body 502.

[0031] Finally, when it is necessary to adjust the angle between the photovoltaic panel body 502 and the sun, by detecting the efficiency of the photovoltaic panel body 502 in real time converting light energy into electrical energy, it is judged whether the photovoltaic panel body 502 is perpendicular to the sunlight at this time. If the conversion efficiency is lower than the preset value, the control unit determines that the photovoltaic panel body 502 is not perpendicular to the sunlight at this time. At this time, the control component controls the slider 401 and the telescopic rod 403 arranged around the photovoltaic installation frame 8 to slide and expand and contract to adjust the inclination angle of the photovoltaic panel body 502, so that the photovoltaic panel body 502 is always perpendicular to the light, and the efficiency of the photovoltaic panel body 502 in converting light energy into electrical energy is improved.

[0032] Two "L"-shaped connecting plates 7 are symmetrically arranged at the bottom of the slider 401. A connecting rod is arranged between two adjacent "L"-shaped connecting plates 7. A roller 8 is sleeved on the connecting rod. The roller 8 is attached to the connecting pipe 2. By arranging the "L"-shaped connecting plate 7 at the bottom of the slider 401 and arranging the roller 8 on the "L"-shaped connecting plate 7, it is convenient to install the slider 401 on the connecting pipe 2, reduce the friction between the connecting pipe 2 and the slider 401, and thus solve the problem that the slider 401 cannot slide on the connecting pipe 2.

[0033] A rotating column 404 is arranged on one side of the telescopic rod 403 on the outermost connecting pipe 2. Rotating columns 404 are respectively arranged on both sides of the telescopic rod 403 on the inner connecting pipe 2. The photovoltaic installation plate 8 between two adjacent connecting pipes 2 is connected to the corresponding telescopic rod 403 through the rotating columns 404 on both sides. By respectively arranging the rotating columns 404 on both sides of the telescopic rod 403 on the inner connecting pipe 2 and connecting the two photovoltaic panel assemblies 5 through the rotating columns 404 respectively, all the photovoltaic panel assemblies 5 located between the two limiting plates 1 can be adjusted at the same angle according to the expansion and contraction of the same group of telescopic rods 403 at the same time, so as to improve the conversion efficiency of the photovoltaic panel assemblies 5.

[0034] The hinge 6 includes a first connecting block and a second connecting block. A plurality of convex blocks are respectively arranged on the first connecting block and the second connecting block, and the convex blocks on the first connecting block and the second connecting block are staggered with each other. The first connecting block and the second connecting block are rotatably connected through a rotating shaft. The adjacent two photovoltaic installation frames 501 are hinged through the hinge block 6 to adjust the included angle between the two photovoltaic installation frames 501, change the connection relationship between the two photovoltaic installation frames 501, and cooperate with the expansion and contraction of the support assembly 4 to adjust the angle of the photovoltaic panel body 502.

[0035] In summary: By providing the sliding block 401 and the telescopic rod 403 thereon on the connecting pipe 2, when it is necessary to convert light energy into electrical energy through the photovoltaic panel body 502, the telescopic rod 403 connected to the photovoltaic panel mounting frame 501 is controlled by the control component to extend or contract, so that the plurality of telescopic rods 403 close to the same side limiting plate 1 extend and drive the photovoltaic mounting frame 8 to deflect upward, and at the same time, the plurality of telescopic rods 403 on the other side contract downward to drive the photovoltaic mounting frame 8 to deflect downward, so that the photovoltaic mounting frame 8 is inclined and mounted on the limiting plate 1 and the connecting pipe 2, improving the efficiency of converting light energy into electrical energy by the photovoltaic panel body 502.

[0036] Embodiment 2

[0037] During actual use, the operator found that when encountering heavy rain or strong wind weather, due to the large undulation of the water surface, the connecting pipe 2 will be bent under the impact of water, resulting in the device being unable to be used normally. At the same time, when it is necessary to clean the garbage in the water area covered by the device, since the device floats on the water surface, the operator cannot clean the garbage located in the middle of the device. Therefore, to solve the above technical problems, the device is improved according to the method described in this embodiment.

[0038] A plurality of air outlets 10 are arrayed on one side of each limiting plate 1. A connecting component is provided inside the limiting plate 1. The connecting component includes a buoyancy chamber 11. An electromagnetic valve is provided between the buoyancy chamber 11 and the air outlet 10. A pressure valve is provided between the buoyancy chamber 11 and the connecting chamber. And the bottom of the buoyancy chamber 11 is communicated with the buoyancy component 3. The buoyancy component 3 includes a floating block 301. The inside of the floating block 301 is a hollow structure. An airbag 302 is provided inside the floating block 301. An electromagnet 303 is provided below the inside of the floating block 301. The electromagnet 303 is located at the outer bottom of the airbag 302 and is connected to the airbag 302. A pressure valve is provided between the buoyancy chamber 11 and the connecting chamber. An electric control valve is provided on the side of the air outlet 10 close to the photovoltaic panel assembly 5. The other side of the air outlet 10 is communicated with the floating block 301 at the bottom of the limiting plate 1 through the buoyancy chamber 11. By opening the air outlets 10 on one side of each limiting plate 1 and connecting the air outlets 10 to the buoyancy component through the connecting component, when it is necessary to clean the dust on the surface of the photovoltaic panel body 502 located between the two limiting plates 1, the control component controls the support component 4 and cooperates with the movement of the driving component 9 to make the photovoltaic panel body 502 parallel to the limiting plate 1. The control component controls the electromagnet 303 at the bottom of the floating block 301 to be energized. Under the magnetic force, the electromagnet 303 squeezes the airbag 302 to move in the direction of the limiting plate 1. During this process, the gas in the airbag 302 will be squeezed into the buoyancy chamber 11 to increase the air pressure in the buoyancy chamber 11. At this time, the control component controls the electromagnetic valve to open, and a large amount of gas is sprayed out through the air outlet 10 onto the photovoltaic panel body 502 to clean the dust on the photovoltaic panel 502.

[0039] On one side of each telescopic base 402 close to the limit plate 1, there is a telescopic block 405. Wedge-shaped holes 406 are opened on both sides of the telescopic block 405. A connection hole 407 is opened in the middle of the side of the telescopic block 405 close to the limit plate 1. A connection cavity penetrating the limit plate 1 is opened on the side of the limit plate 1 opposite to the telescopic block 405. The driving assembly 9 includes a card slot 901, and the card slots 901 are respectively opened at both ends of the connection cavity. A spring 902 is provided in each card slot 901. At the end of the spring 902 away from the card slot 901, there is a wedge-shaped block 903 that is in wedge-shaped fit with the wedge-shaped hole 406. A slider 905 is hermetically and slidably connected in the connection cavity. A push rod 904 is provided on each slider 905, and the push rod 904 matches the connection hole 407. Sealing rings are arranged around the slider 905, and the slider 905 is hermetically and slidably connected to the side wall of the connection cavity through the sealing rings.

[0040] First, when it is necessary to install the support assembly 4 and the limit plate 1, by pushing the sliding block 401 to slide towards the opposite limit plate 1, the telescopic block 405 arranged on the sliding block 401 extends into the connection cavity of the limit plate 1 and pushes the wedge-shaped block 903 to squeeze the spring 902 to expand and contract into the card slot 901. As the telescopic block 405 moves, when the wedge-shaped hole 406 coincides with the card slot 901, the wedge-shaped block 903 will enter the wedge-shaped hole 406 under the elastic force of the spring 902, completing the installation between the support assembly 4 and the limit plate 1. When the water surface fluctuates greatly during the use of the device, the control assembly controls the slider 905 located in the connection cavity to move towards the telescopic block 405 on the same side and drives the push rod 904 to slide in the connection hole 407. During this process, since one end of the telescopic block 405 is restricted by the wedge-shaped block 903 and cannot move outwards, at this time, the push rod 904 will push the telescopic base 402 to move away from the limit plate 1 and make the telescopic block 405 extend, reducing the distance between the two sliding blocks 401 on the same connecting pipe 2. At the same time, the control assembly controls the telescopic rod 403 on the moving sliding block 401 to contract, driving the photovoltaic panel mounting frame 501 connected to the contracted telescopic rod 403 to rotate downwards with the hinge 6 as the center, so that the two photovoltaic panel bodies 9 are distributed in a triangular shape on the connecting pipe 2, thereby enhancing the support of the connecting pipe 2 and preventing the connecting pipe 2 from deforming under the impact of water flow, resulting in the problem that the device cannot work properly.

[0041] Secondly, after the device has been used for a long time, the surface of the photovoltaic panel body 502 will be covered with dust, reducing the conversion efficiency. When the surface of the photovoltaic panel body 502 needs to be cleaned, the control component controls all the telescopic rods 403 to contract simultaneously, and at the same time controls the slider 905 to move away from the telescopic base 402, so that the push rod 904 is separated from the connection hole 407. Since the spring rod is provided in the telescopic block 405, under the action of the elastic force, the telescopic block 405 will drive the sliding block 401 to move towards the limiting plate 1, and cooperate with the contraction of the telescopic rod 403 to adjust the inclined photovoltaic panel assembly 5 to a parallel state. Since the two sliders 905 in the same connection cavity move towards the middle of the connection cavity at the same time, the two sliders 905 will squeeze the gas in the connection cavity. When the pressure value in the connection cavity is greater than the preset value of the pressure valve, the connection cavity will communicate with the buoyancy cavity 11. At this time, the control component opens the connection between the buoyancy cavity 11 and the air outlet 10, and the air is ejected through the air outlet 10 to perform a first-stage cleaning of the dust on the photovoltaic panel body 502. When the photovoltaic panel body 502 returns to the inclined state after cleaning, if the control component detects that the photovoltaic panel body 502 still cannot reach the preset conversion efficiency, at this time, the control component determines that there is still dust on the photovoltaic panel body 502 and it cannot be cleaned only by blowing. The control component repeats the above process to convert the photovoltaic panel body 502 into a parallel state again, and controls the electromagnet 303 at the bottom of the floating block 301 to be energized and generate magnetic attraction with the magnet arranged in the limiting plate 1. Under the action of the magnetic force, the electromagnet 303 squeezes the airbag 302 to move towards the limiting plate 1. During this process, the gas in the airbag 302 will be squeezed into the buoyancy cavity 11 to increase the air pressure in the buoyancy cavity 11. At this time, the control component controls the solenoid valve to open, and a large amount of gas is ejected through the air outlet 10 onto the photovoltaic panel body 502. At this time, since the gas volume in the limiting plate 1 decreases, the buoyancy of the limiting plate 1 on the water will be less than its own gravity, and the limiting plate 1 will move downward, causing the water to submerge the photovoltaic panel body 502. At this time, the control component controls the telescopic rod 403 to continuously extend and contract and cooperate with the movement of the slider 905 in the connection cavity to continuously convert the photovoltaic panel body 502 from a parallel state to an inclined state, and the adhered dust on the photovoltaic panel body 502 is cleaned in the second stage by the lake water, thus solving the problem that the surface of the photovoltaic panel body 502 will be covered with dust and the conversion efficiency is reduced.

[0042] It should be noted that when the control component controls the two sliders 905 in the same connection cavity to continuously approach and move away from each other, the control component controls the regulating valve to open to connect the connection cavity with the air inlet pipe, and the outside air is inhaled into the connection cavity through the reciprocating movement of the two sliders 905 to compensate for the consumed air in the buoyancy cavity 11, preventing the device from sinking to the bottom of the lake due to insufficient buoyancy.

[0043] Finally, when it is necessary to clean the lake surface garbage within the coverage area of the device, the control component is used to control the telescopic rod 403 to contract and cooperate with the slider 905 to move towards the middle of the connection cavity, converting the inclined photovoltaic panel assembly 5 into a horizontal state. When both sides of the two photovoltaic panel mounting frames 501 connected by the hinge 6 are kept on the same horizontal plane driven by the sliding block 401, since there is no support structure at the bottom of the connection between the two photovoltaic panel mounting frames 501 and the hinge 6, at this time, under the action of gravity, the hinge 6 will drive the two photovoltaic panel mounting frames 501 on both sides to bend downward. During this process, the control component discharges the gas in the limiting plate 1 to make the limiting plate 1 drive the photovoltaic panel assembly 5 to sink. At the same time, the control component controls the slider 905 to move towards the direction close to the telescopic base 402, reducing the distance between the two sliding blocks 401, changing the two parallel photovoltaic panel bodies 502 into a "V" - shaped structure, pushing the garbage covered by the photovoltaic panel assembly 5 towards the two limiting plates 1 on both sides, making the garbage move above the limiting plates 1, and supplementing the air in the limiting plates 1 by controlling the reciprocating movement of the slider 905 to make the limiting plates 1 float upward from underwater, collecting the garbage covered by the photovoltaic panel assembly 5 above the limiting plates 1, which is convenient for the staff to clean and recycle the garbage in this water area.
