There are many types of photovoltaic solar brackets, including ground brackets, roof brackets, carport brackets, etc. Different types of brackets are suitable for different installation locations.

[0003] Patent No. "CN212870279U" discloses a "photovoltaic solar bracket". This device achieves a firm and reliable connection between two adjacent solar panels and the inclined support beam on a soft ground through the ingenious structural design of the fastening installation components, thereby ensuring the stability of the photovoltaic solar bracket. Since the existing solar brackets only achieve a simple supporting effect on photovoltaic panels, and since photovoltaic panels are all exposed to the air during use, as the use time increases, dust and impurities such as fallen leaves will appear on the surface of the photovoltaic panels.

[0025] The rotation control mechanism 5 includes a limit support plate 51, a drive motor 52 and a limit shaft 53. The limit support plate 51 is symmetrically arranged on the top outer wall of the support base plate 1. There are two limit support plates 51. The side outer wall of one of the limit support plates 51 is provided with a drive motor 52. The drive motor 52 is connected to one end of the limit shaft 53. The other end of the limit shaft 53 is rotatably installed with the side inner wall of the limit support plate 51. The top outer wall of the limit shaft 53 is provided with a support bar 54, and the top outer wall of the support bar 54 is connected to the bottom outer wall of the installation frame 2. The bottom outer wall of the installation frame 2 is symmetrically and slidably installed with a first support member 55.

The positioning block 58 and the positioning groove 59 There is a sliding connection between them; when the orientation angle of the photovoltaic panel 3 needs to be adjusted, the driving motor 52 needs to be turned on first. When the driving motor 52 is turned on, it will automatically drive the limit shaft 53 to rotate and then drive the support bar 54 to rotate. Then the rotation of the support bar 54 will automatically drive the mounting frame 2 to rotate and then drive the photovoltaic panel 3 to adjust the angle. When the photovoltaic panel 3 is adjusted to a suitable angle, the driving motor 52 can be turned off. It is noted here that the driving motor 52 has a self-locking function. After being turned off, the photovoltaic panel 3 can still maintain the adjusted angle unchanged. At the same time, the above-mentioned mounting frame 2 will also synchronously drive the first support member 55 to slide at the bottom end of the mounting frame 2 while rotating. Then the movement of the first support member 55 will automatically drive the auxiliary plate 57 to move and then drive the second support member 56 to move. When the second support member 56 moves, it will automatically drive the positioning block 58 inside the positioning groove 59. At the same time, the setting of the positioning block 58 and the positioning groove 59 has a limiting support effect on the movement of the second support member 56.

[0026] The bottom outer wall of the photovoltaic panel 3 is provided with a supporting pad 61, and the side outer wall of the supporting pad 61 is provided with a mounting strip 62.

When the photovoltaic panel 3 needs to be replaced, at this time, it is only necessary to pull the mounting strip 62 to the horizontal side until the photovoltaic panel 3 is completely separated from the mounting frame 2. During installation, it is first necessary to adjust the limiting T-shaped strip 63 at the bottom end of the supporting pad 61 to a suitable position and then push it to the limiting T-shaped groove 65 until the contact card column 64 is snapped into the inside of the contact card groove 66 to complete the installation of the photovoltaic panel 3.

[0027] The portable cleaning mechanism 7 includes a limit box 71, a micro motor 72, a reciprocating screw rod 73 and an auxiliary strip 74.

The micro motor 72 is connected to one end of the reciprocating screw rod 73, and the other end of the reciprocating screw rod 73 is rotatably installed with the side inner wall of the limit box 71. The side of the reciprocating screw rod 73 is provided with an auxiliary strip 74 in parallel, and both ends of the auxiliary strip 74 are connected to the side inner wall of the limit box 71. A limit block 75 is provided outside the reciprocating screw rod 73 and the auxiliary strip 74. The inner walls on both sides of the limit block 75 are slidably installed with the side inner wall of the limit box 71. The top outer wall of the limit block 75 is provided with a connecting block 76, and the connecting block 76 is set in an "L" shape. The side outer wall of the connecting block 76 is connected to the side outer wall of the support frame 77, and the support frame 77 is set The outside of the limit box 71 and the bottom inner wall of the support frame 77 are provided with a cleaning pad 78, and the bottom outer wall of the cleaning pad 78 is in contact with the top outer wall of the photovoltaic panel 3; when the outer wall of the photovoltaic panel 3 needs to be cleaned, the micro motor 72 needs to be turned on first. The setting of the limit box 71 here protects the micro motor 72. When the micro motor 72 is turned on, it will automatically drive the reciprocating screw rod 73 to rotate and then drive the limit block 75 to move. Due to the setting of the auxiliary strip 74 here, the reciprocating screw rod 73 will only drive the limit block 75 to realize the horizontal sliding trajectory movement when rotating. Then, the movement of the limit block 75 will automatically drive the connecting block 76 to move and then drive the support frame 77 to move. When the support frame 77 moves, it will automatically drive the cleaning pad 78 to move, and the debris accumulated on the photovoltaic panel 3 will be cleaned up along the moving trajectory of the cleaning pad 78.

[0028] When the photovoltaic panel 3 is adjusted to a suitable angle, the driving motor 52 can be turned off. It is noted that the driving motor 52 has a self-locking function. After being turned off, the photovoltaic panel 3 can still maintain the adjusted angle unchanged. At the same time, when the above-mentioned mounting frame 2 rotates, it will also synchronously drive the first supporting member 55 to slide on the bottom end of the mounting frame 2. Then, the movement of the first supporting member 55 will automatically drive the auxiliary plate 57 to move and then drive the second supporting member 56 to move. When the second supporting member 56 moves, it will automatically drive the positioning block 58 to be inside the positioning groove 59. At the same time, the positioning block 58 and the positioning groove 59 are set to the movement of the second supporting member 56. It plays a limiting support effect; when the photovoltaic panel 3 needs to be replaced, it is only necessary to pull the installation strip 62 to the horizontal side until the photovoltaic panel 3 is completely separated from the installation frame 2. During installation, it is first necessary to adjust the limiting T-shaped strip 63 at the bottom of the support pad 61 to a suitable position and then push it into the limiting T-shaped groove 65 until the contacting clamping column 64 is engaged with the inside of the contacting clamping groove 66 to complete the installation of the photovoltaic panel 3; when the outer wall of the photovoltaic panel 3 needs to be cleaned, it is first necessary to turn on the micro motor 72. The setting of the limit box 71 here plays a role in the micro motor 72 In order to achieve the protective effect, when the micro motor 72 is turned on, it will automatically drive the reciprocating screw 73 to rotate and then drive the limit block 75 to move. Here, due to the setting of the auxiliary strip 74, the reciprocating screw 73 will only drive the limit block 75 to realize the horizontal sliding trajectory movement when rotating. Then, the movement of the limit block 75 will automatically drive the connecting block 76 to move and then drive the support frame 77 to move. When the support frame 77 moves, it will automatically drive the cleaning pad 78 to move. Along the moving trajectory of the cleaning pad 78, the debris accumulated on the photovoltaic panel 3 will be cleaned up.
