[0002] Photovoltaic panels, also known as solar panels, are devices that directly convert sunlight into electrical energy using the photovoltaic effect. When photons strike a photovoltaic cell, their energy is absorbed by silicon atoms, exciting electrons to jump from the valence band to the conduction band, thus forming electron-hole pairs. Under the influence of the electric field inside the cell, the electrons and holes are separated and form a current in the external circuit, thereby generating electrical energy. Photovoltaic panels are widely used in solar power generation systems and are an important component of clean and renewable energy. However, during the use of photovoltaic panels, dust and debris often accumulate on their surface.

[0018] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0019] Please see Figure 1-7 As shown in the figure, this embodiment provides a photovoltaic module support that is easy to maintain. Figure 1-2 As shown, the system includes a base joint plate 1, with multiple fixed limiting frames 2 fixedly connected to the bottom of the base joint plate 1. Specifically, the multiple fixed limiting frames 2 are arranged linearly and equidistantly at the bottom of the base joint plate 1. The purpose of this arrangement is to allow the base joint plate to be buried along the inclined slope during construction and installation. The multiple fixed limiting frames 2 buried in the inclined slope can be inserted into the soil to prevent the base joint plate 1 from loosening and to enhance the overall stability of the base joint plate. Optionally, the depth of the fixed limiting frames 2 can be set according to the actual installation environment. The longer the depth, the better the stability limiting effect. After the burial construction is completed, the burial surface can also be sealed.

[0020] Reference Figure 6-7 As shown, a support mechanism 3 is provided above the base joint plate 1. The support mechanism 3 includes a semi-circular adjusting slide frame 31 fixedly connected to the top surface of the base joint plate 1. A connecting support clamp 32 is slidably connected inside the semi-circular adjusting slide frame 31. A limiting slide rod 33 penetrating the side wall of the semi-circular adjusting slide frame 31 is fixedly connected to the side of the connecting support clamp 32. The limiting slide rod 33 can slide along the semi-circular adjusting slide frame 31 with the connecting support clamp 32. A calibration locking member 34 is rotatably connected to one end of the limiting slide rod 33 extending out of the outer wall of the semi-circular adjusting slide frame 31. Multiple openings are provided on the side of the semi-circular adjusting slide frame 31. The positioning hole 35 matches the calibration locking member 34. The internal part of the connecting support clamp 32 is rotatably connected to a rotating support toothed plate 36. The lower part of the rotating support toothed plate 36 is engaged with a fixed half toothed plate 37 that is fixedly connected to the base connecting plate 1. When the connecting support clamp 32 slides, the rotating support toothed plate 36 can rotate along the periphery of the fixed half toothed plate 37. The upper part of the connecting support clamp 32 is also provided with a photovoltaic support plate 44 for supporting photovoltaic modules. The photovoltaic support plate 44 can slide along the semi-circular adjusting slide frame 31 with the connecting support clamp 32 and is locked in the positioning hole 35 by the calibration locking member 34.

[0021] Understandably, after construction and installation are completed, workers can make the connecting support clamp 32 and the limiting slide rod 33 slide synchronously inside the semi-circular adjusting slide frame 31, so that the rotating support toothed plate 36 can rotate and move synchronously around the outer wall of the fixed half toothed plate 37, thereby changing the tilt angle of the connecting support clamp 32. This allows the overall installation angle of the photovoltaic support plate 44 used to support the photovoltaic module to be adjusted, so that sunlight can hit the photovoltaic module surface more vertically. After adjustment, the calibration locking member 34 can be engaged with the positioning hole 35 at the corresponding position, and then locked with positioning bolts. The above structure, through the cooperation of the semi-circular adjusting slide frame 31, the connecting support clamp 32, the rotating support toothed plate 36 and the fixed half toothed plate 37, allows the photovoltaic module to be stably supported on the base plate. At the same time, it allows the photovoltaic bracket to be easily installed on the inclined slope, and the angle of the photovoltaic module can be adjusted according to the inclined slope. This not only improves the installation efficiency of the photovoltaic module in complex environments, but also ensures the photoelectric conversion efficiency.

[0022] Furthermore, the length of the connecting support plate 32 is the same as the outer circumferential radius of the semi-circular adjusting slide frame 31. The connecting support plate 32 and the base connecting plate 1 are rotatably connected. The connection point between the connecting support plate 32 and the base connecting plate 1 is at the center of the semi-circular adjusting slide frame 31. The center of the fixed half-tooth plate 37 coincides with the center of the semi-circular adjusting slide frame 31.

[0023] Specifically, the purpose of this design is that when rotating the connecting support plate 32, the mutual limiting between the limiting slide rod 33 and the semi-circular adjusting slide frame 31 makes the sliding of the connecting support plate 32 more stable and smooth, thereby making the angle adjustment of the connecting support plate 32 more convenient.

[0024] Furthermore, combined Figure 3-4 As shown, it also includes a steering mechanism 4, which includes a first connecting rod 41 rotatably connected to the top of the connecting support plate 32. A first transverse support plate 42 is fixedly installed on the upper part of the first connecting rod 41, and a second connecting rod 43, which is vertically arranged, is fixedly installed on the top of the first transverse support plate 42. A photovoltaic support plate 44 is installed on the top of the second connecting rod 43. Specifically, the purpose of this arrangement is to keep the first connecting rod 41 and the connecting support plate 32 on the same vertical line. Thus, when the connecting support plate 32 is slidably deflected, the first connecting rod 41 can drive the photovoltaic support plate 44 to tilt synchronously around the outer circumferential surface of the semi-circular adjusting slide frame 31, so as to be able to adjust and use according to slopes of different gradients.

[0025] Wherein, a second transverse support plate 45 parallel to the first transverse support plate 42 is fixedly installed at the lower part of the first connecting support rod 41, a dual-axis motor 46 is fixedly installed at the bottom of the second transverse support plate 45, a first transmission gear 47 is fixedly connected to the lower output shaft end of the dual-axis motor 46, an adjusting gear plate 48 rotatably connected to the first connecting support rod 41 is meshed on the outer wall of the first transmission gear 47, and the adjusting gear plate 48 is fixedly installed on the top of the connecting support clamp 32.

[0026] Specifically, the purpose of this arrangement is to enable the first transmission gear 47 to rotate when the dual-axis motor 46 is started, so that the first transmission gear 47 can rotate the second transverse support plate 45 around the outer wall of the first connecting support rod 41, thereby causing the first connecting support rod 41 to drive the first transverse support plate 42 and the photovoltaic support plate 44 to rotate synchronously, thereby adjusting the orientation of the photovoltaic support plate 44.

[0027] In practical implementation, under normal conditions, the connecting support plate 32 is vertically positioned at the vertical centerline of the semi-circular adjusting slide frame 31. When the mounting surface is flat, it can be as follows: Figure 1-2 The photovoltaic support plate 44 is positioned and installed as shown. When the mounting surface is inclined, the deflection and sliding connection support plate 32 causes the first connecting rod 41 to rotate around the outer wall of the semi-circular adjusting slide frame 31. After adjustment, the alignment locking piece 34 is aligned with the positioning hole 35 at the corresponding position, and then the positioning bolts are tightened to fix the support angle of the connection support plate 32 and the adjustment mechanism 4. Then, the dual-axis motor 46 is started to make the first transmission gear 47 rotate around the outer wall of the adjustment gear plate 48, which causes the first connecting rod 41 to rotate the photovoltaic support plate 44, thereby adjusting the orientation of the photovoltaic support plate 44.

[0028] It should be noted that in complex environments, dust easily accumulates on the surface of photovoltaic modules, affecting their photoelectric conversion efficiency. Therefore, further design modifications can be made to the alignment mechanism 4, as detailed below:

[0029] More preferably, refer to Figure 4-5As shown, a second transmission gear 49, which is fixedly connected to the dual-axis motor 46, is rotatably mounted on the top of the second transverse support plate 45. A connecting rod 411 is rotatably mounted on the bottom of the first transverse support plate 42. A third transmission gear 412 is fixedly connected to the bottom of the connecting rod 411. A transmission belt 413 meshes with the outer walls of both the connecting rod 411 and the third transmission gear 412. Specifically, the purpose of this arrangement is to ensure that while the dual-axis motor 46 drives the first transmission gear 47 to rotate and adjust the orientation of the photovoltaic support plate 44, the second transmission gear 49 rotates synchronously. This, in turn, combined with the transmission belt 413 meshing with the second transmission gear 49, synchronously drives the third transmission gear 412 and the connecting rod 411 to rotate as a whole.

[0030] Furthermore, refer to Figure 5 As shown, a horizontally positioned balance support frame 410 is fixedly installed at the bottom of the first transverse support plate 42. The connecting rod 411 is rotatably installed inside the balance support frame 410. A directional slider 415 is slidably installed on one side of the balance support frame 410. A connecting sleeve 416 that is slidably connected to the photovoltaic support plate 44 is hinged to the top of the directional slider 415. A cleaning brush 417 that is parallel to the photovoltaic support plate 44 is fixedly installed on the top of the connecting sleeve 416.

[0031] In practical use, the connecting sliding sleeve 416 allows the cleaning brush 417 to be tilted and adjusted according to the installation angle of the photovoltaic support plate 44 during installation, so that the cleaning brush 417 always remains parallel to the surface of the photovoltaic support plate 44. Then, when the directional slider 415 slides on one side of the balance support frame 410, the cleaning brush 417 can slide synchronously on the surface of the photovoltaic support plate 44 to remove dust and impurities from the surface of the photovoltaic support plate 44. This prevents the surface of the photovoltaic support plate 44 from being covered with dust and blocking sunlight from entering the energy conversion zone inside the photovoltaic support plate 44, thereby reducing the light absorption rate of the photovoltaic support plate 44 and affecting the power generation efficiency of the photovoltaic support plate 44.

[0032] At the same time, refer to Figure 5 As shown, a fourth transmission gear 414, which is fixedly connected to the connecting rod 411, is rotatably mounted on the bottom of the balance support 410. The outer wall of the fourth transmission gear 414 is meshed with a guide rack 418, which is fixedly connected to the directional slider 415. In actual use, when the fourth transmission gear 414 is rotated by the rotating connecting rod 411, the guide rack 418 can drive the directional slider 415 to move as a whole, thereby allowing the cleaning brush 417 to move smoothly on the surface of the photovoltaic support plate 44 to wipe away the dust on the surface of the photovoltaic support plate 44.

[0033] In practice, the initial installation of the photovoltaic support plate 44 is completed by first adjusting the support angle of the connecting support plate 32 by deflection and sliding and fixing it in position. Then, the dual-axis motor 46 is started to make the first transmission gear 47 and the second transmission gear 49 rotate synchronously. When the first transmission gear 47 rotates around the outer wall of the directional tooth plate 48, the orientation of the photovoltaic support plate 44 is adjusted. At the same time, the rotating second transmission gear 49 drives the third transmission gear 412 to rotate through the transmission belt 413, which causes the connecting rod 411 to drive the fourth transmission gear 414 to rotate. This causes the guide rack 418 to move horizontally synchronously on the outer wall of the fourth transmission gear 414, so that the cleaning brush 417 can be attached to the surface of the photovoltaic support plate 44 to move and scrape to remove impurities.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
