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 solar photovoltaic panel supporting equipment thereof. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to convert light directly 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 panels are currently the most common devices for converting solar energy. To improve solar energy conversion efficiency, they are installed diagonally on brackets, with the panel frames secured to the bracket beams via clamps. This method of mounting the panels requires alignment and careful handling due to their large size, weight, and brittle material. The installation process is time-consuming, labor-intensive, and inconvenient, as the clamps only secure the panels in a specific location. Furthermore, since the clamps only secure the panels in a specific location, the load on them is concentrated, making them susceptible to damage.

[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 folding into a V-shape to remove snow is not good; secondly, although it does not need to be folded in windy and rainy weather, leaves and the like that fall on the solar panels are not easy to fall off and need to be manually cleaned later. If they are not cleaned, the power generation of the solar panels will be affected.

[0005] In addition, in windy and rainy weather, the photovoltaic panels supported by the existing technology are tilted and vibrate due to the wind. If they are not effectively protected, the line joints will be damaged or have poor contact, affecting their normal power generation. However, the existing technology rarely has corresponding protection measures. For this reason, the present application proposes a photovoltaic power generation system and its solar photovoltaic panel support equipment. Summary of the Invention

[0014] Preferably, it further comprises a guide mechanism for guiding the steel wire rope, wherein the guide mechanism comprises a wheel frame mounted on a support frame, a guide wheel is rotatably connected to the wheel frame, and the steel wire rope is wound around the guide wheel.

[0015] Preferably, it further comprises a cleaning mechanism capable of cleaning the photovoltaic panel, wherein the cleaning mechanism comprises a brush fixed on the two first T-blocks, and the brush can be pressed against the shielding net and the photovoltaic panel.

[0017] Preferably, it also includes a plurality of reset mechanisms installed on the water storage rectangular frame and the baffle plate to enable the baffle 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 is passed through the L-shaped block and is slidably connected to the guide rod, the guide rod is fixedly connected to the baffle plate, a second spring is fixed on the baffle plate, and the other end of the second spring is fixedly connected to the L-shaped block.

[0018] The present invention also discloses a photovoltaic power generation system, which further includes a storage module. The storage module is used to store the electrical energy converted by the photovoltaic panels. The electric push rod and the controller are connected to the storage module.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 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.

[0021] 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 forming ice on the photovoltaic panels, which is difficult to thaw and affect the photovoltaic panels' light generation and power generation.

[0022] 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 will not 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 breaks away 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 reset process of the first spring, it reciprocates and contracts with the amplitude gradually decreasing, causing the first T-block to move back and forth, causing the shielding net to vibrate. Since the shielding net is in a tilted state, the broken ice can be separated from the shielding net, thereby partially cleaning the shielding net and clearing the snow on it to a certain extent.

[0023] 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, thereby cleaning the photovoltaic panel. The reciprocating movement of the brush can drive the shielding net to deform and break the ice to a certain extent.

[0024] 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 away from the shielding net due to gravity. The leaves can also be cleaned when there is wind blowing through the shielding net.

[0025] 6. When the shielding net changes from a horizontal state to an inclined state, the shielding net will pass through the transmission roller. The transmission roller guidance 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, so as not to affect the photovoltaic panel's lighting and power generation.

[0026] 7. In windy and rainy weather, rainwater is stored in the water storage rectangular frame. During the installation process of the panel, the block contacts the L-shaped panel and drives the L-shaped panel to move. The movement of the L-shaped panel drives the shielding panel to move. At this time, the second spring is compressed, and the shielding panel no longer seals the bottom of the water storage rectangular frame. The collected rainwater can be discharged and guided by the L-shaped panel to flow to the photovoltaic panel cleaned by the panel brush. The photovoltaic panel can be further rinsed to achieve cleaning of the photovoltaic panel.

[0027] 8. Since photovoltaic panels do not need to be folded, the wiring requirements are low, which reduces the difficulty of production.

[0028] 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 that the photovoltaic panel can generate light and generate electricity. The panel brush moves back and forth to clean the photovoltaic panel and the shielding net, and is further cleaned by using transmission 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.

[0047] The present invention further discloses a photovoltaic power generation system, which includes a storage module for storing electrical energy converted by the photovoltaic panels. The electric push rod 20 and the controller 14 are connected to the storage module.

[0048] When the present invention is used, the electric push rod 20 drives the mounting frame 4 to rotate upward. Since one end of the shielding net 15 is fixed on the mounting plate 21, when the mounting frame 4 drives the bracket 12 to rotate, the shielding net 15 and the mounting plate 9 and the mounting frame 4 move relative to each other. 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 light generation. At this time, the counterweight plate 7 moves upward under the pull of the wire rope 8.

[0049] When there is strong wind and heavy rain, 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 strong wind and heavy rain, they will only fall on the shielding net 15 and will not affect the photovoltaic panel 5, so there is no need for subsequent manual cleaning.

[0050] Since the mounting frame 4 and the photovoltaic panel 5 are in a horizontal state at this time, gusts of wind will have little impact on the photovoltaic panel 5 in a horizontal state during strong winds and heavy rains. This will prevent the mounting frame 4 and the photovoltaic panel 5 from vibrating due to wind and rain, thereby protecting the mounting frame 4 and the photovoltaic panel 5 and ensuring stable wire connection.

[0051] Similarly, if it is hail or rain and snow 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, preventing snowflakes from accumulating on the photovoltaic panel 5 and then freezing on the photovoltaic panel 5, which is difficult to thaw and affect the photovoltaic panel 5's light and power generation.

[0052] 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 1As shown in the figure, when the counterweight plate 7 moves up and hits 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 does not move. 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. At this time, the wire rope 8 is no longer limited. Under the action of the compressed first spring 24, the first T-shaped block 27 is reset, which can drive the wire rope 8 and the counterweight plate 7 to move upward. During the reset process of the first spring 24, the reciprocating extension and contraction and the amplitude gradually decreases, so that the first T-shaped block 27 moves back and forth; when the counterweight plate 7 again contacts the limit block 6, the above process is repeated, so that the scrub brush 23 can be reciprocated. In windy or snowy weather, the reciprocating scrub brush 23 can be used to scrub the dust on the surface of the photovoltaic panel 5, thereby cleaning the photovoltaic panel 5;

[0053] The scrubbing brush 23 will also come into contact with the shielding net 15. Due to the rainy and snowy weather, ice will form on the shielding net 15. The scrubbing brush 23 will reciprocate to a certain extent, which can 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, thereby partially cleaning the shielding net 15 and also cleaning the snow on it to a certain extent.

[0054] It should be noted that when wet leaves are on the shielding net 15, the scrub 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 fall away from the shielding net 15 due to gravity, and the leaves can be cleaned when wind blows through the shielding net 15;

[0055] In addition, when the shielding net 15 changes from a horizontal state to an inclined state, the shielding net 15 passes through the transmission roller 22. The transmission roller 22 guides the ice on the shielding net 15 to break, which is conducive to detaching from the shielding net 15 and melting. It can also remove the snow on the shielding net 15, so as not to affect the photovoltaic panel 5 lighting and power generation.

[0056] In windy and rainy weather, rainwater is stored in the water storage rectangular frame 13. When the plate 9 is installed, the stopper 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, so that the collected rainwater can be discharged and guided by the L-shaped plate 30 to flow onto the photovoltaic panel 5 cleaned by the brush 23, so that the photovoltaic panel 5 can be further rinsed to achieve cleaning of the photovoltaic panel 5.

[0057] 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.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
