Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation system and a solar photovoltaic panel supporting device thereof. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light into electrical energy. It is widely used in solar power generation. As a clean and environmentally friendly green energy product, solar photovoltaic panels are increasingly used in production and life.

[0003] Solar photovoltaic panel components are currently the most common devices for converting solar energy. In order to improve the conversion efficiency of solar energy, photovoltaic panel components are all set obliquely on the bracket, and the frame of the component is fixed to the bracket beam by a pressure block. When installing photovoltaic panel components in this fixing method, the position of the component needs to be adjusted for alignment. Since the photovoltaic panel components are large in area, heavy in weight, and made of hard and brittle materials, they need to be handled with great caution. Therefore, the entire installation process is time-consuming, laborious, and inconvenient. In addition, since the pressure block only fixes the local position of the photovoltaic panel component, the load it receives is relatively concentrated, which can easily cause damage to the photovoltaic panel component.

[0004] The prior art application number is CN202310464621.4, which is a photovoltaic power generation system and a solar photovoltaic panel support device. Although it can solve the above-mentioned technical problems, it is very difficult to arrange the lines and the effect of snow removal when folded into a V-shape is not good; secondly, although it does not need to be folded in windy and rainy weather, leaves and the like fall on the solar panels and are not easy to fall off. Manual cleaning is required later. If it is not cleaned, it will affect the power generation of the solar panels.

[0005] In addition, in windy and rainy weather, the tilted photovoltaic panels in the prior art vibrate due to the wind. If they are not effectively protected, the line joints may be damaged or have poor contact, affecting their normal power generation.

For this reason, the present application proposes a photovoltaic power generation system and a solar photovoltaic panel support device thereof. Summary of the invention

[0012] Preferably, it also includes a guiding mechanism for guiding the steel wire rope, the guiding mechanism includes a wheel frame installed on the support frame, the wheel frame is rotatably connected to a guide wheel, and the steel wire rope is wound around the guide wheel.

[0013] Preferably, it also includes a cleaning mechanism capable of cleaning the photovoltaic panel, wherein the cleaning mechanism includes a brush fixed on two first T-blocks, and the brush can be against the shielding net and the photovoltaic panel.

[0014] Preferably, it also includes a flushing mechanism, which includes a water storage rectangular frame fixed on a bracket, a shielding plate is slidably provided on the bottom of the water storage rectangular frame, and the shielding plate can shield the bottom of the water storage rectangular frame, an L-shaped plate is fixed on the shielding plate, and two blocks are fixed on the movable plate that can resist the L-shaped plate and drive the L-shaped plate and the shielding plate to move.

[0015] Preferably, it also includes a plurality of reset mechanisms installed on the water storage rectangular frame and the shielding plate to enable the shielding plate to move stably, the reset mechanism includes two mounting blocks fixed on the L-shaped plate, a telescopic rod is fixed on the mounting block and the water storage rectangular frame, an L-shaped block is fixed on the water storage rectangular frame, a guide rod slidably connected to the L-shaped block is passed through the L-shaped block, the guide rod is fixedly connected to the shielding plate, a second spring is fixed on the shielding plate, and the other end of the second spring is fixedly connected to the L-shaped block.

[0016] The present invention also discloses a photovoltaic power generation system, which further comprises a storage module, wherein the storage module is used to store the electric energy converted by the photovoltaic panel, and the electric push rod and the controller are connected to the storage module.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the intelligent control of the controller and the electric push rod, the present invention can automatically adjust the angle of the solar photovoltaic panel according to the wind speed. In windy and rainy weather, the photovoltaic panel can automatically adjust to a horizontal state and be shielded by a shielding net, effectively avoiding the direct impact of wind and rain on the photovoltaic panel and protecting the stability of the connection between the photovoltaic panel and the wires.

[0018] 2. Hail and snow fall on the tight shielding net, which can buffer and shield the falling hail, thus effectively avoiding damage to the photovoltaic panels; snow also falls on the shielding net to prevent snowflakes from accumulating on the photovoltaic panels and then freezing on the photovoltaic panels, which is difficult to thaw and affects the photovoltaic panels' lighting and power generation.

[0019] 3. When the counterweight plate moves up and hits the bottom of the limit block, the counterweight plate cannot move up, thereby hindering the movement of the wire rope, and finally feedback is given to the first T-block so that it cannot be used. The continuous movement of the second T-block will squeeze the first spring. As the moving plate and the second T-block move up, the compression of the first spring increases, and finally the counterweight plate and the limit block rotate relative to each other, and finally the counterweight plate separates from the limit block. At this time, the wire rope is no longer limited, and under the action of the compressed first spring, the first T-block is reset, which can drive the wire rope and the counterweight plate to move up. During the resetting process of the first spring, it reciprocates and expands and contracts with the amplitude gradually decreasing, so that the first T-block moves back and forth, causing the shielding net to vibrate. Since the shielding net is in an inclined state, the broken ice can be separated from the shielding net, so that the shielding net can be partially cleaned, and the snow on it can also be cleaned to a certain extent.

[0020] 4. The brush can move back and forth. In windy, rainy or snowy weather, the dust on the surface of the photovoltaic panel can be scrubbed by the brush to clean the photovoltaic panel. The reciprocating movement of the brush can drive the shielding net to deform to a certain extent to break the ice.

[0021] 5. When wet leaves are on the shielding net, the brush cannot effectively clean the leaves on the shielding net. When the installation frame and the photovoltaic panel are reset, the shielding net is in a tilted state and some leaves will fall off the shielding net due to gravity. The leaves can also be cleaned when wind blows through the shielding net.

[0022] 6. When the shielding net changes from a horizontal state to an inclined state, the shielding net will pass through the transmission roller. The guidance of the transmission roller can break the ice on the shielding net, which is conducive to detaching from the shielding net and melting. It can also remove the snow on the shielding net, which will not affect the photovoltaic panel lighting and power generation.

[0023] 7. In windy and rainy weather, rainwater is stored in the water storage rectangular frame. When the board is installed, the block contacts the L-shaped board and drives the L-shaped board to move. The movement of the L-shaped board drives the shielding board to move. At this time, the second spring is compressed, and the shielding board no longer seals the bottom of the water storage rectangular frame. The collected rainwater can be discharged and flowed to the photovoltaic panel cleaned by the board brush through the guidance of the L-shaped board. The photovoltaic panel can be further rinsed to achieve cleaning of the photovoltaic panel.

[0024] 8. Since photovoltaic panels do not need to be folded, the wiring requirements are low, which reduces the difficulty of production.

[0025] In summary, the present invention realizes automatic adjustment of the angle of the photovoltaic panel through intelligent control, effectively avoids direct impact of wind and rain, and protects the stability of the photovoltaic panel and wire connection. At the same time, the tight shielding net can buffer hail and block snow, ensuring the photovoltaic panel to generate electricity. The panel brush moves back and forth to clean the photovoltaic panel and the shielding net, and is further cleaned by driving rollers and rainwater. In addition, the photovoltaic panel does not need to be folded, which reduces wiring requirements and production difficulty, and improves overall stability and power generation efficiency.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 9 , a solar photovoltaic panel supporting device, comprising a supporting frame 1, and four supporting legs 2 are installed at the bottom of the supporting frame 1: A solar photovoltaic panel support assembly; the solar photovoltaic panel support assembly includes a mounting frame 4 which is rotatably mounted on the upper end of a support frame 1 and can adjust the angle, a mounting frame 3 is fixed to the bottom of the support frame 1, a connecting plate 17 is fixed to the bottom of the mounting frame 4, a first connecting frame 18 is fixedly connected to the connecting plate 17, a second connecting frame 19 is fixedly connected to the mounting frame 3, an electric push rod 20 is hingedly connected to the second connecting frame 19, an output end of the electric push rod 20 is hingedly connected to the first connecting frame 18, and the output end of the electric push rod 20 is telescopically connected to drive the first connecting frame 18, the connecting plate 17 and the adjustment of the angle of the mounting frame 3, and the electric push rod 20 also rotates with it, so that the mounting frame 4 can be stored in a horizontal state; wherein, a controller 14 connected to the electric push rod 20 is installed on the bracket 12, and a wind speed sensor is arranged in the controller 14. When the wind speed reaches a set value, the controller controls the electric push rod 20 to work, and it can also be remotely controlled manually.

[0030] A plurality of photovoltaic panels 5 are mounted on the mounting frame 4, a movable plate 9 is slidably connected to the mounting frame 4, a mounting plate 21 is fixedly connected to the support frame 1, a shielding net 15 is mounted on the mounting plate 21, and the other end of the shielding net 15 is fixed on the movable plate 9. In order to guide the shielding net 15 so that it is always parallel to the photovoltaic panel 5, a transmission mechanism is also included. The transmission mechanism includes a bracket 12 fixed on the mounting frame 4, the bracket 12 is rotatably connected to a transmission roller 22, and the shielding net 15 is wound around the transmission roller 22.

[0031] The mounting plate 9 is connected to a counterweight plate 7 that can move up and down. When the mounting frame 4 rotates upward, the shielding net 15 does not block the photovoltaic panel 5. When the mounting frame 4 rotates downward, the shielding net 15 gradually blocks the photovoltaic panel 5. When the mounting frame 4 rotates, the shielding net 15 can vibrate. It also includes a vibration mechanism that vibrates the shielding net 15. The vibration mechanism includes a T-slot 11 arranged at the upper end of the mounting frame 4. A first T-block 27 and a second T-block 28 are slidably connected in the T-slot 11. It also includes a cleaning mechanism that can clean the photovoltaic panel 5. The cleaning mechanism includes a brush 23 fixed on the two first T-blocks 27. The brush 23 can resist the shielding net 15 and the photovoltaic panel 5.

[0032] The second T-block 28 is arranged close to the counterweight plate 7, and the movable plate 9 is fixed on the two second T-blocks 28. The first spring 24 is fixed on the first T-block 27 and the second T-block 28. A through groove 29 is penetrated on the second T-block 28. A steel wire rope 8 is fixed on the first T-block 27. The steel wire rope 8 penetrates the through groove 29 and is fixedly connected to the counterweight plate 7.

[0033] It also includes a guiding mechanism for guiding the wire rope 8, which includes a wheel frame 25 installed on the support frame 1, and a guide wheel 26 is rotatably connected to the wheel frame 25. The wire rope 8 is wound around the guide wheel 26. The wire rope 8 is arranged on a side close to the counterweight plate 7. The counterweight plate 7 is inclined in a vertical state. A plurality of limit blocks 6 are fixed on the two supporting legs 2 close to the counterweight plate 7. The counterweight plate 7 can be against the limit blocks 6 when moving upward or downward.

[0034] The flushing mechanism also includes a water storage rectangular frame 13 fixed on the bracket 12, and a baffle plate 16 is slidably provided at the bottom of the water storage rectangular frame 13. The baffle plate 16 can block the bottom of the water storage rectangular frame 13, and an L-shaped plate 30 is fixed on the baffle plate 16. Two blocks 10 that can resist the L-shaped plate 30 and drive the L-shaped plate 30 and the baffle plate 16 to move are fixed on the movable plate 9. It also includes a plurality of reset mechanisms installed on the water storage rectangular frame 13 and the baffle plate 16 to enable the baffle plate 16 to move stably. The reset mechanism includes two mounting blocks 34 fixed on the L-shaped plate 30, and a telescopic rod 35 is fixed on the mounting block 34 and the water storage rectangular frame 13. An L-shaped block 32 is fixed on the water storage rectangular frame 13. A guide rod 31 slidably connected to the L-shaped block 32 is penetrated by the L-shaped block 32, and the guide rod 31 is fixedly connected to the baffle plate 16. A second spring 33 is fixed on the baffle plate 16, and the other end of the second spring 33 is fixedly connected to the L-shaped block 32.

[0035] The present invention also discloses a photovoltaic power generation system, which includes a storage module for storing electric energy converted by the photovoltaic panel. The electric push rod 20 and the controller 14 are connected to the storage module.

[0036] When the present invention is used, the electric push rod 20 drives the installation frame 4 to rotate upward. Since one end of the shielding net 15 is fixed on the installation plate 21, when the installation frame 4 drives the bracket 12 to rotate, the shielding net 15 and the installation plate 9 move relative to the installation frame 4. The first T-block 27 and the second T-block 28 slide in the T-slot 11. Finally, the shielding net 15 no longer blocks the photovoltaic panel 5 and the photovoltaic panel 5 is in an inclined state, which is conducive to lighting and power generation. At this time, the counterweight plate 7 moves upward through the pulling of the wire rope 8; When it is windy and rainy, the controller 14 detects that the wind speed is greater than the set value, and the controller 14 controls the electric push rod 20 to work. The electric push rod 20 drives the installation frame 4 and the photovoltaic panel 5 to be in a horizontal shape. With the cooperation of the counterweight plate 7 and the wire rope 8, it can drive the first T-block 27, the second T-block 28 and the installation plate 9 to move, and then drive the shielding net 15 to move. When the installation frame 4 is in a horizontal state, the shielding net 15 completely shields the photovoltaic panel 5. Due to the setting of the counterweight plate 7, the shielding net 15 is in a taut state. Even if leaves fall in windy and rainy weather, they will only fall on the shielding net 15, and will not affect the photovoltaic panel 5, and no subsequent manual cleaning is required; Since the installation frame 4 and the photovoltaic panel 5 are in a horizontal state at this time, in windy and rainy weather, gusts of wind have little effect on the photovoltaic panel 5 in a horizontal state, so that the installation frame 4 and the photovoltaic panel 5 are not easily vibrated by wind and rain, thereby protecting the installation frame 4 and the photovoltaic panel 5 and ensuring stable wire connection; Similarly, if it is hail or rainy and snowy weather, the electric push rod 20 can be manually controlled, and the hail and snow will fall on the tight shielding net 15. The tight shielding net 15 can buffer and shield the falling hail, which can effectively avoid damage to the photovoltaic panel 5; snow also falls on the shielding net 15 to prevent snowflakes from accumulating on the photovoltaic panel 5 and then freezing on the photovoltaic panel 5, which is difficult to thaw and affects the photovoltaic panel 5 for light generation.

[0037] When the sky is clear, the electric push rod 20 is started to drive the installation frame 4 and the photovoltaic panel 5 to rotate upward and reset again. At this time, the counterweight plate 7 is pulled upward by the wire rope 8. Figure 1 As shown in the counterweight plate 7, when the counterweight plate 7 moves up and contacts the bottom of the limit block 6, the counterweight plate 7 cannot move up, thereby hindering the movement of the wire rope 8, and finally feedback is given to the first T-block 27 so that it cannot be used. The second T-block 28 continues to move and squeezes the first spring 24. As the moving plate 9 and the second T-block 28 move up, the compression amount of the first spring 24 increases, and finally the counterweight plate 7 and the limit block 6 rotate relative to each other, and finally the counterweight plate 7 is separated from the limit block 6, and the wire rope 8 is no longer limited. Under the action of the compressed first spring 24, the first T-block 27 is reset, so that the steel wire rope 8 and the counterweight plate 7 can be driven to move upward. During the reset process of the first spring 24, the first spring 24 reciprocates and retracts with the amplitude gradually decreasing, so that the first T-block 27 reciprocates; when the counterweight plate 7 abuts against the limit block 6 again, the above is repeated, so that the brush 23 can reciprocate. In windy, rainy or snowy weather, the dust on the surface of the photovoltaic panel 5 can be scrubbed by the reciprocating brush 23, so that the photovoltaic panel 5 can be cleaned; The brush 23 will also collide with the shielding net 15. Due to the rainy and snowy weather, ice will form on the shielding net 15. The brush 23 can reciprocate to a certain extent to drive the shielding net 15 to deform and break the ice, and also make the shielding net 15 shake. Since the shielding net 15 is in an inclined state, the broken ice can be separated from the shielding net 15, so as to partially clean the shielding net 15 and also clean the snow on it to a certain extent. It should be noted that when wet leaves are on the shielding net 15, the brush 23 cannot effectively clean the leaves on the shielding net 15. When the mounting frame 4 and the photovoltaic panel 5 are reset, the shielding net 15 is in a tilted state. Figure 2 , Figure 3 As shown, some leaves will be separated from the shielding net 15 due to gravity, and the leaves can also be cleaned when wind blows through the shielding net 15; In addition, when the shielding net 15 changes from a horizontal state to an inclined state, the shielding net 15 will pass through the transmission roller 22. The ice on the shielding net 15 can be broken by the guidance of the transmission roller 22, which is conducive to detaching from the shielding net 15 and melting. The snow on the shielding net 15 can also be removed, so that the photovoltaic panel 5 will not be affected in the light generation. In windy and rainy weather, rainwater is stored in the water storage rectangular frame 13. When the plate 9 is installed, the block 10 abuts against the L-shaped plate 30 and drives the L-shaped plate 30 to move. The movement of the L-shaped plate 30 drives the shielding plate 16 to move. At this time, the second spring 33 is compressed, and the shielding plate 16 no longer seals the bottom of the water storage rectangular frame 13. The collected rainwater can be discharged and guided by the L-shaped plate 30 to flow to the photovoltaic panel 5 cleaned by the brush 23. The photovoltaic panel 5 can be further rinsed to achieve cleaning of the photovoltaic panel 5. It should be noted that the upper end of the L-shaped plate 30 is lower than the upper end of the shielding plate 16, so as not to hinder the flow of collected rainwater.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
