Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and more specifically, to a photovoltaic bracket with a self-protection structure. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic brackets are commonly used components when installing photovoltaic panels, and play a very important role in ensuring the stability of photovoltaic panels.

[0003] When common photovoltaic brackets are used to support photovoltaic panels, they are affected by strong winds and sand will directly impact the surface of the photovoltaic panels, causing wear and tear of the photovoltaic panels. The common treatment method is to cover the photovoltaic panels with protective plates to protect them. However, the protective plates need to be installed later, and the setting of the protective plates will cause certain obstruction to the lighting of the photovoltaic panels, affecting the power generation efficiency of the photovoltaic panels.

With the help of the mutual engagement of the rack and the gear, the gear can be pulled to drive the carrier column to rotate, so that the carrier column drives the left photovoltaic panel to rotate 180°. At this time, the lighting surfaces of the two photovoltaic panels correspond to each other. With the help of two screws driven by a dual-axis motor, the two photovoltaic panels can be driven to approach each other and stick together in a screw transmission manner, so that the lighting surfaces of the photovoltaic panels protect each other and are not easily damaged by the impact of wind and sand.

[0021] Use the angle adjustment component to adjust the photovoltaic panel 12 to a vertical state, use the first electric push rod 9 to push the carrier block 10 to pull the rack 11 to move, and with the help of the mutual engagement of the rack 11 and the gear 7, the gear 7 can be pulled to drive the carrier column 6 to rotate, so that the carrier column 6 drives the left photovoltaic panel 12 to rotate 180°. At this time, the lighting surfaces of the two photovoltaic panels 12 correspond to each other. With the help of the two screws 2 driven by the dual-axis motor 3, the two photovoltaic panels 12 can be driven to approach each other and stick together in a screw transmission manner, so that the lighting surfaces of the photovoltaic panels 12 protect each other.

[0022] A base 13 is fixed to the bottom of the rectangular frame plate 1 , a plurality of mounting holes 14 are provided on the base 13 , an anemometer 15 is provided on the upper surface of the rectangular frame plate 1 , a control module 16 is provided on the front side of the base 13 , and the anemometer 15 is electrically connected to the control module 16 .

[0023] The anemometer 15 is used to monitor the external wind speed. If the wind speed is too high, the impact of wind and sand will increase. The control module 16 cooperates with the anemometer 15 to drive the two photovoltaic panels 12 closer together in time to form mutual protection.

[0024] Among them, the angle adjustment component includes a U-shaped seat 17 and two U-shaped blocks 18. A carrier tube 19 is rotatably connected between the relative inner walls of the U-shaped seat 17 through a pin shaft. A connecting block 20 is fixed to the outer wall of the carrier tube 19.

[0027] When in use, the base 13 is fixed at a designated position, and the photovoltaic panel 12 is installed on the connecting block 20, with the lighting surface of the photovoltaic panel 12 facing the sun. The photovoltaic panel 12 is used to convert light energy into electrical energy. The anemometer 15 monitors the wind speed in the environment where the photovoltaic panel 12 is located. When the wind speed is too high, the sand and gravel mixed in the wind have a strong impact force.

With the help of the mutual meshing of the rack 11 and the gear 7, the gear 7 can be pulled to drive the carrier column 6 to rotate, so that the carrier column 6 drives the left photovoltaic panel 12 to rotate 180° in the horizontal direction. At this time, the lighting surfaces of the two photovoltaic panels 12 correspond to each other, and the control module 16 controls the dual-axis motor 3 to drive the two screw rods 2 to rotate, so that the two screw rods 2 pull the two photovoltaic panels 12 closer to each other in a screw rod transmission manner until the two photovoltaic panels 12 are in contact with each other. The lighting surfaces of the two photovoltaic panels 12 protect each other, and the outer shell of the photovoltaic panel 12 can block the impact of wind and sand to ensure the safety of the lighting surface of the photovoltaic panel 12 until the wind speed decreases, and then the control module 16 controls the two photovoltaic panels 12 to reset.
