Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically to a wind protection device for a new energy photovoltaic power station. Background Art

[0002] With the continuous increase in the global demand for renewable energy, photovoltaic power generation, as a clean and sustainable energy form, has been widely applied. A new energy photovoltaic power station is a photovoltaic power generation system that utilizes solar energy and is composed of electronic components such as crystalline silicon panels through special materials, and is connected to the power grid and transmits electricity to the power grid.

[0003] Existing photovoltaic power stations usually use fixed mounting frames to support photovoltaic panels. When encountering strong wind weather, since the connection between the photovoltaic panels and the mounting frames is rigid, uneven wind pressure distribution may lead to local stress concentration, and then cause deformation or even fracture of the photovoltaic panels or mounting frames, thus increasing the risk of damage.

[0004] In addition, in strong wind weather, particulate matters such as dust and sand carried in the air are likely to fall on the surface of the photovoltaic panels. Dust not only blocks sunlight and reduces the light absorption efficiency of the photovoltaic panels, but also forms a dirt layer that is difficult to remove due to long-term accumulation, seriously affecting the power generation efficiency of the photovoltaic panels.

[0005] Therefore, it is necessary to provide a wind protection device for a new energy photovoltaic power station to solve the technical problems proposed in the above background art. Summary of the Invention

When the wind is normal, the first electric telescopic cylinder and the second electric cylinder body extend synchronously, the shielding plate opens, and the photovoltaic panels are unfolded at an angle. When the wind sensor detects strong wind, the first electric telescopic cylinder and the second electric telescopic cylinder body contract synchronously, and the photovoltaic panels are retracted into the shielding plate, which can significantly reduce the direct impact of the wind on the photovoltaic panels, reduce the wind load, and thus effectively protect the photovoltaic panels from wind damage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0041] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0042] Please refer to Figures 1 - 5 , an anti-wind protection device for a new energy photovoltaic power station provided by an embodiment of the present invention includes:

[0043] A support frame 1, which is fixedly arranged on the ground. A wind sensor is fixedly arranged on the support frame 1, and a chassis 2 is installed on the support frame 1;

[0044] A photovoltaic mechanism 3, which is installed on the support frame 1;

[0045] A driving mechanism 4, which is fixedly arranged at the rear side of the support frame 1; and

[0046] An auxiliary mechanism 5, which is movably arranged horizontally on the support frame 1, and the driving mechanism 4 is used to drive the movement of the auxiliary mechanism 5.

[0047] Based on the above technical solution, during the normal working process, that is, when the wind sensor monitors that the wind force is within the normal range, the driving mechanism 4 drives the auxiliary mechanism 5 to open, and the photovoltaic mechanism 3 extends out of the auxiliary mechanism 5; when the wind sensor monitors that the wind force exceeds the normal range, the driving mechanism 4 drives the auxiliary mechanism 5 to close, and the photovoltaic mechanism 3 retracts into the auxiliary mechanism 5, so that the direct impact of strong wind on the photovoltaic mechanism 3 can be significantly reduced, the wind load can be reduced, and thus the photovoltaic mechanism 3 can be effectively protected from wind damage.

[0048] In a possible implementation manner, upper limit slots 11 and lower limit slots 12 are symmetrically opened on both the front and rear sides of the support frame 1.

[0049] In a possible implementation manner, the photovoltaic mechanism 3 includes:

[0050] An installation shaft 31;

[0051] The rotating frame 32 is symmetrically and rotatably arranged on the mounting shaft 31, and a plurality of the rotating frames 32 are rotatably arranged in the axial direction of the mounting shaft 31. Photovoltaic panels 33 are fixedly arranged at the upper ends of the rotating frames 32;

[0052] The guiding shafts 34 are configured to be two, and they are rotatably arranged at the lower ends of the symmetric rotating frames 32. The first sliding blocks 35 are arranged on the guiding shafts 34 at the outermost front and rear positions of the plurality of rotating frames 32 in a limited rotation manner, and the first sliding blocks 35 are movably arranged in the lower limiting grooves 12.

[0053] Through the above technical solution, when the mounting shaft 31 rises, the first sliding blocks 35 move towards each other along the lower limiting grooves 12, and the rotating frames 32 and the photovoltaic panels 33 are unfolded at a certain angle; when the mounting shaft 31 descends, the first sliding blocks 35 move relative to each other along the lower limiting grooves 12, and the rotating frames 32 and the photovoltaic panels 33 return to the horizontally unfolded state.

[0054] In a possible implementation manner, a first electric telescopic cylinder 21 is fixedly arranged at the upper end of the chassis 2. The number of the first electric telescopic cylinders 21 is half of the number of the rotating frames 32, and the mounting shaft 31 between the symmetric rotating frames 32 is rotatably connected to the output end of the first electric telescopic cylinder 21. That is, when the first electric telescopic cylinder 21 extends, the mounting shaft 31 rises; when the first electric telescopic cylinder 21 contracts, the mounting shaft 31 descends.

[0055] In a possible implementation manner, the driving mechanism 4 includes:

[0056] A bottom plate 41 is fixedly arranged at the rear side of the support frame 1. Grooved pulleys 42 are rotatably arranged on the left and right sides of the bottom plate 41, and a pulling belt 43 is sleeved between the grooved pulleys 42;

[0057] A first clamping plate 44 is arranged on the pulling belt 43 close to the photovoltaic mechanism 3;

[0058] A second clamping plate 45 is arranged on the pulling belt 43 far from the photovoltaic mechanism 3; and

[0059] A second electric telescopic cylinder 46 is fixedly arranged on the bottom plate 41 far from the photovoltaic mechanism 3, and the output end of the second electric telescopic cylinder 46 is fixedly arranged with the second clamping plate 45.

[0060] With the above technical solution, when the second electric telescopic cylinder 46 extends, the second clamping plate 45 drives the pulling belt 43 to rotate clockwise along the grooved pulley 42, and the horizontal lateral distance between the first clamping plate 44 and the second clamping plate 45 increases; when the second electric telescopic cylinder 46 contracts, the second clamping plate 45 drives the pulling belt 43 to rotate counterclockwise along the grooved pulley 42, and the horizontal lateral distance between the first clamping plate 44 and the second clamping plate 45 decreases.

[0061] In a possible implementation manner, the auxiliary mechanism 5 includes a first closed cleaning component 51 and a second closed cleaning component 52 that are respectively movably arranged on the left and right sides of the support frame 1, and the first closed cleaning component 51 and the second closed cleaning component 52 are symmetrically arranged on the left and right sides of the support frame 1. The first closed cleaning component 51 and the second closed cleaning component 52 can passively clean the surface of the photovoltaic panel 33 during the movement process.

[0062] In a possible implementation manner, part of the structures of the first closed cleaning component 51 and the second closed cleaning component 52 are the same, and both include:

[0063] A support plate 511, with second sliding blocks 512 fixedly arranged on both the front and rear sides thereof. The second sliding blocks 512 are all movably arranged in the upper limit groove 11. One side of the support plate 511 close to the driving mechanism 4 is fixedly arranged with the second clamping plate 45, and a shielding plate 513 is fixedly arranged at the upper end of the support plate 511. A transparent window 514 is fixedly arranged in the shielding plate 513; and

[0064] Automatic telescopic rods 515, configured to be two, are symmetrically and fixedly arranged horizontally in the front and rear of the lower end of the shielding plate 513 away from the support plate 511. A roller brush 516 is rotatably arranged between the lower ends of the two automatic telescopic rods 515.

[0065] With the above technical solution, when the second electric telescopic cylinder 46 extends, the second sliding block 512 moves relatively along the upper limit groove 11, and the shielding plate 513 also moves relatively. The photovoltaic panel 33 can be unfolded at any angle (0 - 90°) between the shielding plates 513, that is, the photovoltaic panel 33 is in a normal working state at this time; when the second electric telescopic cylinder 46 contracts, the second sliding block 512 moves towards each other along the upper limit groove 11, and the shielding plates 513 also move towards each other. The photovoltaic panel 33 contracts between the shielding plates 513 until it is unfolded horizontally, that is, the photovoltaic panel 33 is in a retracting working state at this time.

[0066] On the basis of the above technical solution, the photovoltaic panel 33 is unfolded at an angle and restored to the horizontal unfolded state. The support plates 511 move towards each other. Under the action of the automatic telescopic rod 515, the roller brush 516 is always in contact with the surface of the photovoltaic panel 33. The roller brush 516 can passively remove the dust on the photovoltaic panel 33 for the first time. During the process of the photovoltaic panel 33 being restored from the horizontal unfolded state to the angled unfolded state, the support plates 511 move relatively, and the roller brush 516 can passively remove the dust on the photovoltaic panel 33 for the second time and sweep the dust on the photovoltaic panel 33 off, which can effectively remove dust, sand particles and other pollutants, ensure the cleanliness of the surface of the photovoltaic panel 33, enable the clean photovoltaic panel 33 to absorb sunlight more efficiently, and improve the photoelectric conversion efficiency.

[0067] It should be added that in rainy days, a rain monitoring sensor can be installed on the support frame 1. When the rain monitoring sensor detects a large amount of rainfall, it feeds back to control both the second electric telescopic cylinder body 46 and the first electric telescopic cylinder 21 to contract. The photovoltaic panel 33 contracts into the shielding plate 513, and the photovoltaic panel 33 can receive sunlight through the transparent window 514, thereby reducing the wear and corrosion of the photovoltaic panel 33 caused by rain, extending the service life of the photovoltaic panel 33, and reducing the maintenance cost.

[0068] In a possible implementation manner, the second closed cleaning assembly 52 further includes a top baffle 521 fixedly arranged at the upper end of the support plate 511 located on the second closed cleaning assembly 52. The top baffle 521 can guide rainwater to flow along the shielding plate 513, prevent rainwater from entering the chassis 2, and reduce circuit failures.

[0069] In a possible implementation manner, the shielding plates 513 located on the first closed cleaning assembly 51 and the second closed cleaning assembly 52 are symmetrically arranged, and the height of the proximal end of the shielding plate 513 located on the first closed cleaning assembly 51 and the shielding plate 513 located on the second closed cleaning assembly 52 is greater than the height of the distal end, so that dust can be taken away from the surface of the transparent window 514 in strong winds and rainy days, enabling the photovoltaic panel 33 to work normally in extreme weather.

[0070] In a possible implementation manner, a power storage device, a control system and a power distribution system are installed in the chassis 2, and the wind sensor, the control system, the first electric telescopic cylinder 21, and the second electric telescopic cylinder 46 are all electrically connected to the power storage device. The wind sensor is connected to the control system, and the control system is respectively connected to the first electric telescopic cylinder 21 and the second electric telescopic cylinder 46. After the wind sensor monitors the wind force, it feeds back to the control system, and the control system then controls the expansion and contraction of the first electric telescopic cylinder 21 and the second electric telescopic cylinder 46.

[0071] In specific implementation, during the normal working process, that is, when the wind sensor monitors that the wind force is within the normal range, the control system controls the second electric telescopic cylinder body 46 and the first electric telescopic cylinder body 21 to extend. The second sliding block 512 moves relatively along the upper limit groove 11, the shielding plate 513 moves relatively, and the synchronous mounting shaft 31 rises. The first sliding block 35 moves towards each other along the lower limit groove 12, and the photovoltaic panel 33 unfolds at a certain angle. The photovoltaic panel 33 is passively cleaned by the roller brush 516.

[0072] When the wind sensor monitors that the wind force exceeds the normal range, the control system controls both the second electric telescopic cylinder body 46 and the first electric telescopic cylinder body 21 to contract. The second sliding block 512 moves towards each other along the upper limit groove 11, the shielding plate 513 moves towards each other, and the synchronous mounting shaft 31 descends. The first sliding block 35 moves relatively along the lower limit groove 12, and the photovoltaic panel 33 gradually returns to the horizontally unfolded state. At this time, the photovoltaic panel 33 is passively cleaned by the roller brush 516.

[0073] The above-mentioned is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
