Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically to an adaptive adjustment device for photovoltaic panels. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are the most important part of solar cells. They are thin photovoltaic semiconductor wafers that directly generate electricity using sunlight. As long as they are exposed to light under certain illumination conditions, they can instantly output voltage and generate current when a circuit is established. In physics, this is called solar photovoltaic, or simply photovoltaic.

[0003] The shortcomings of existing technologies: Photovoltaic panels are generally installed outdoors and are extremely susceptible to the continuous impact of extreme weather. Storms can not only induce structural resonance and mechanical overload, but also cause loose component connections, electrical faults, and even structural damage. When snow covers photovoltaic panels, if it is not removed in time, it will directly cause a sharp drop in power generation, which will seriously affect the reliability and safety of the long-term operation of the photovoltaic system. To address this, we propose an adaptive adjustment device for photovoltaic panels. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adaptive adjustment device for photovoltaic power generation panels to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: an adaptive adjustment device for photovoltaic panels, comprising a base, an upper end of which is connected to a mounting frame via a connecting rod, the mounting frame being provided with an adjustment component, the adjustment component including a folding mechanism and a rotating mechanism, the rotating mechanism including a fixed connecting plate, a movable connecting plate, a rotating shaft and a positioning seat, a set of fixed connecting plates being installed in the mounting frame, the surface of the mounting frame having multiple sets of sliding grooves, multiple sets of movable connecting plates being slidably connected in the sliding grooves via sliders, the fixed connecting plate being located above the multiple movable connecting plates, the rotating shaft being installed in both the fixed and movable connecting plates, and the positioning seat being installed on the end face of the rotating shaft, the positioning seat being used to clamp the photovoltaic panel; The folding mechanism includes a first threaded rod, a threaded block, a limiting block, and a limiting groove. A pair of first threaded rods are rotatably connected in the mounting frame. The threaded block is slidably connected in the mounting frame and threadedly connected to the first threaded rod. The limiting blocks are all installed at the lower ends of the fixed connecting plate and the moving connecting plate. The threaded block is fixedly connected to the lowermost limiting block by threads. The limiting grooves are all opened on the surfaces of the fixed connecting plate and the moving connecting plate. The limiting block and the limiting groove are slidably connected. Preferably, a connecting buckle is installed at the end of the rotating shaft away from the positioning seat, a plurality of rotating frames are installed on the surface of the mounting frame, a connecting shaft is rotatably connected inside each rotating frame, a connecting block is installed on the end face of the connecting shaft, and the connecting block matches the groove provided on the connecting buckle.

[0006] Preferably, a bidirectional motor is installed inside the mounting frame, and a rotating shaft is installed at the output end of each bidirectional motor. The rotating shaft is rotatably connected to the mounting frame, and the rotating shaft is connected to the connecting shaft through a first sprocket set. The connecting shafts are connected to each other through a second sprocket set.

[0007] Preferably, a pair of slide blocks are installed on the surfaces of both the fixed connecting plate and the moving connecting plate. A sliding shaft is slidably connected inside the slide block. An extrusion block is installed on the end face of the sliding shaft. A spring is installed between the extrusion block and the slide block. The positioning seat is located between the corresponding pair of extrusion blocks.

[0008] Preferably, a servo motor is installed inside the mounting bracket, and a drive shaft is installed at the output end of the servo motor. The drive shaft is connected to the first threaded rod through a third sprocket set.

[0009] Preferably, except for the bottom of the photovoltaic panel, a first connecting strip is installed at the bottom of each of the photovoltaic panels, and a first cotton strip is installed at the bottom of each of the first connecting strips.

[0012] The technical effects and advantages of this invention are as follows: When the wind is strong, the rotating shaft drives the positioning seat to rotate, and the photovoltaic panel adjusts its angle according to the signal transmitted by the wind direction sensor, so that the photovoltaic panel is adjusted to the minimum windward angle in real time. From an aerodynamic point of view, this fundamentally reduces the load on the photovoltaic panel. In the event of a blizzard, the folding mechanism will fold and store multiple moving connecting plates under the fixed connecting plate, thereby folding multiple photovoltaic panels and reducing the wind resistance. Then, the rotating shaft is controlled to rotate, driving the positioning seat and photovoltaic panels to rotate simultaneously, so that the back of the photovoltaic panel faces upward. In the face of wind and snow, this not only reduces the wind-exposed area and ensures the stability of the equipment, but also prevents snow from accumulating on the front of the photovoltaic panel, which would affect the energy conversion efficiency of the photovoltaic panel.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adaptive adjustment device for photovoltaic panels involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1-12 As shown, in one embodiment, an adaptive adjustment device for a photovoltaic panel is proposed, including a base 1. The upper end of the base 1 is connected to a mounting frame 102 via a connecting rod 101. The mounting frame 102 is provided with an adjustment component 2, which includes a folding mechanism 21 and a rotating mechanism 22. The rotating mechanism 22 includes a fixed connecting plate 221, a movable connecting plate 226, a rotating shaft 224, and a positioning seat 225. A set of fixed connecting plates 221 are installed in the mounting frame 102. Multiple sets of sliding grooves 222 are formed on the surface of the mounting frame 102. Multiple sets of movable connecting plates 226 are slidably connected in the sliding grooves 222 via sliders 223. The fixed connecting plates 221 are located above the multiple movable connecting plates 226. The rotating shaft 224 is installed in both the fixed connecting plate 221 and the movable connecting plate 226. The positioning seat 225 is installed on the end face of the rotating shaft 224. The positioning seat 225 is used to clamp the photovoltaic panel 3. The folding mechanism 21 includes a first threaded rod 211, a threaded block 212, a limiting block 213, and a limiting groove 214. A pair of first threaded rods 211 are rotatably connected in the mounting frame 102. The threaded block 212 is slidably connected in the mounting frame 102 and threadedly connected to the first threaded rod 211. The limiting blocks 213 are all installed at the lower ends of the fixed connecting plate 221 and the movable connecting plate 226. The threaded block 212 and the lowermost limiting block 213 are fixedly connected by threads. The limiting grooves 214 are all opened on the surfaces of the fixed connecting plate 221 and the movable connecting plate 226. The limiting block 213 and the limiting groove 214 are slidably connected.

[0017] In practical applications, when the wind is strong, sensors installed on the device transmit signals to the controller. The controller controls the rotation of the rotating shaft 224, which in turn rotates the positioning seat 225. The positioning seat 225 then rotates the photovoltaic panel 3. The photovoltaic panel 3 adjusts its angle according to the signals transmitted by the wind direction sensor, ensuring it is adjusted to the minimum windward angle in real time. This fundamentally reduces the load on the photovoltaic panel 3 from an aerodynamic perspective. Furthermore, when the photovoltaic panel 3 is adjusted to the minimum windward angle, its front surface avoids direct contact with the wind, preventing dust carried by the wind from directly contacting the front surface and reducing dust accumulation. In the event of a blizzard... The air controls the rotation of the first threaded rod 211, which in turn drives the threaded block 212 to move upward. The threaded block 212 then drives the lowest limiting block 213 to move diagonally upward, thereby driving the lowest moving connecting plate 226 and the photovoltaic panel 3 to move diagonally upward. As the lowest moving connecting plate 226 continues to move, the limiting groove 214 on the lowest moving connecting plate 226 will abut against the adjacent upper limiting block 213, which will then drive the adjacent upper moving connecting plate 226 and the photovoltaic panel 3 to move upward until the threaded block 212 reaches its uppermost limit position. At this point, all the moving connecting plates 226 will be folded and stored under the fixed connecting plate 221, thereby folding the multiple photovoltaic panels 3. Figure 11 As shown, the wind resistance is reduced, and then the rotating shaft 224 is controlled to rotate, causing the positioning seat 225 and the photovoltaic panel 3 to rotate simultaneously, so that the back of the photovoltaic panel 3 faces upwards, as shown. Figure 12 As shown, when facing windy and snowy weather, it not only reduces the wind-receiving area and ensures the stability of the equipment, but also prevents snow from accumulating on the front of the photovoltaic panel 3, which would affect the energy conversion efficiency of the photovoltaic panel 3.

[0018] like Figure 2-4 As shown, in one embodiment, a connecting buckle 4 is installed at the end of the rotating shaft 224 away from the positioning seat 225. A plurality of rotating frames 401 are installed on the surface of the mounting bracket 102. A connecting shaft 402 is rotatably connected inside each rotating frame 401. A connecting block 403 is installed on the end face of the connecting shaft 402. The connecting block 403 matches the groove provided on the connecting buckle 4.

[0019] In practical application, the connecting shaft 402 is controlled to rotate, which in turn drives the connecting block 403 to rotate. When the connecting block 403 coincides with the connecting buckle 4, the connecting buckle 4 can be driven to rotate. The connecting buckle 4 drives the rotating shaft 224 and the positioning seat 225 to rotate, thereby achieving the effect of adjusting the angle of the photovoltaic panel 3.

[0020] like Figure 2 , 3As shown in Figures 9 and 10, in one embodiment, a bidirectional motor 5 is installed inside the mounting bracket 102. Each output end of the bidirectional motor 5 is equipped with a rotating shaft 501. The rotating shaft 501 is rotatably connected to the mounting bracket 102. The rotating shaft 501 is connected to the connecting shaft 402 through a first sprocket set 502. The connecting shafts 402 are connected to each other through a second sprocket set 503.

[0021] In practical application, the embodiments of the present invention control the bidirectional motor 5 to operate, the bidirectional motor 5 drives the rotating shaft 501 to rotate, the rotating shaft 501 drives the connecting shaft 402 to rotate through the first sprocket group 502, and at the same time through the action of the second sprocket group 503, multiple connecting shafts 402 can be rotated simultaneously, thereby achieving the effect of controlling the operation of the rotating mechanism 22.

[0022] like Figure 6 and 7 As shown, in one embodiment, a pair of slide blocks 6 are installed on the surfaces of the fixed connecting plate 221 and the movable connecting plate 226. A sliding shaft 601 is slidably connected inside the slide block 6. An extrusion block 602 is installed on the end face of the sliding shaft 601. A spring 603 is installed between the extrusion block 602 and the slide block 6. The positioning seat 225 is located between the corresponding pair of extrusion blocks 602.

[0023] In practical application, when the moving connecting plate 226 moves upward and folds, the connecting buckle 4 will disengage from the connecting block 403. At this time, through the action of the spring 603, the spring 603 pushes the pressing block 602 to fit against the positioning seat 225, restricting the position of the positioning seat 225, so that the positioning seat 225 and the connecting buckle 4 are parallel to the mounting frame 102, thereby keeping the angle of the connecting buckle 4 on the moving connecting plate 226 unchanged. After the moving connecting plate 226 is folded, the connecting buckle 4 will overlap with the upper connecting block 403, controlling the rotation of the connecting block 403 to fold multiple photovoltaic panels 3 together. Then, the photovoltaic panels 3 can be controlled to rotate simultaneously again to adjust the angle of the photovoltaic panels 3 so that the back of the folded photovoltaic panels 3 faces upward. This not only reduces the wind-receiving area but also avoids the situation of snow accumulation on the front, improving the stability of the equipment in windy and snowy weather, and also reducing the frequency of later maintenance.

[0024] like Figure 9-11 As shown, in one embodiment, a servo motor 7 is installed in the mounting bracket 102, and a drive shaft 701 is installed at the output end of the servo motor 7. The drive shaft 701 is connected to the first threaded rod 211 through a third sprocket set 702.

[0025] In practical application, the embodiment of the present invention controls the operation of the servo motor 7, which drives the drive shaft 701 to rotate. The drive shaft 701, through the action of the third sprocket group 702, can drive the first threaded rod 211 to rotate, thereby achieving the effect of controlling the operation of the folding mechanism 21.

[0026] like Figure 6 and 10 As shown, in one embodiment, except for the lower end of the bottom photovoltaic panel 3, a first connecting strip 8 is installed, and a first cotton strip 801 is installed at the lower end of each of the first connecting strips 8.

[0027] In practical applications, when the folding mechanism 21 is in operation, the first cotton strip 801 can slide against the surface of the photovoltaic panel 3 installed in the moving connecting plate 226 to clean some impurities on its surface, thus preventing large impurities from blocking the front of the photovoltaic panel 3 and affecting the energy conversion efficiency.

[0028] like Figure 1 , 5 As shown in Figure 10, in one embodiment, the upper end of the mounting bracket 102 is provided with a guide groove 9, a sliding bracket 901 is slidably connected in the guide groove 9, a second connecting strip 902 is installed at the lower end of the sliding bracket 901, and a second cotton strip 903 is installed at the lower end of the second connecting strip 902.

[0029] In practical application, the sliding frame 901 is controlled to slide in the guide groove 9, which can drive the second connecting strip 902 and the second cotton strip 903 to slide, so that the photovoltaic panel 3 installed between the second cotton strip 903 and the fixed connecting plate 221 slides, cleaning some impurities on its surface, and avoiding large impurities from blocking the front of the photovoltaic panel 3 and affecting the energy conversion efficiency.

[0030] like Figure 11 and 12 As shown, in one embodiment, a second threaded rod 904 is rotatably connected inside the mounting bracket 102. The second threaded rod 904 is threadedly connected to the sliding bracket 901, and the second threaded rod 904 is connected to the first threaded rod 211 through a fourth sprocket set 905.

[0031] In practical application, since the threads of the first threaded rod 211 and the second threaded rod 904 are opposite and have different pitches, when the first threaded rod 211 drives the moving connecting plate 226 to move upward, the second threaded rod 904 will drive the sliding frame 901 to move downward through the action of the fourth sprocket group 905. After the moving connecting plate 226 is folded, the second cotton strip 903 will move to the lowest limit position, achieving the effect of cleaning impurities from the surface of the uppermost photovoltaic panel 3.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
