Background Art

Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

After searching, the Chinese patent with announcement number CN211183866U discloses a protective device for photovoltaic solar power generation panels, including a support plate, two support plates, and stabilizing mechanisms are arranged on both sides of the bottom ends of the two support plates. A lifting motor is fixedly installed at the middle bottom ends of the two support plates, and the output end of the lifting motor passes through the support plate and is fixedly connected with a screw rod. The two screw rods are fixed by the coordinated use of the set support rod, the mounting seat, the support plate and the expansion bolt. At the same time, a moving block is threadedly installed on the screw rod, which is convenient for loading and unloading the equipment and convenient for maintenance. When it is necessary to increase the height of the solar photovoltaic panel, the screw rod is driven to rotate by the lifting motor, so that the two moving blocks are driven to rise and fall on the screw rod through the screw rod, which is convenient for adjusting the height of the solar photovoltaic panel, improving the light absorption efficiency of the solar photovoltaic panel, and at the same time, in severe weather conditions, the height of the solar photovoltaic panel is reduced, so that the center of gravity of the entire solar photovoltaic panel is lowered, thereby improving stability.

However, in the above technical solution, the protective net is pulled out from the opening of the reel only by driving the movable end of the protective mesh frame through the threaded sleeve to cover the photovoltaic panel to achieve protection.

At the same time, the protection component does not occupy the space on the mounting plate 8, so that the solar panel 2 will not be blocked and its working efficiency will not be affected.

Embodiment 2

As shown in Figures 1 to 3, the protective device for photovoltaic solar panels proposed by the utility model, compared with the first embodiment, in this embodiment, the lifting assembly includes a motor 4, a threaded rod 5, a sliding block 6, a connecting shaft 7, a mounting plate 8 and a protective assembly capable of preventing damage to the photovoltaic panel, the symmetrically arranged threaded rods 5 are rotatably connected to both sides of the base 1, the bottom of the threaded rod 5 passes through the base 1 and is transmission-connected to the output end of the motor 4 connected to the base 1, the mounting plate 8 is arranged between the threaded rods 5, both ends of the mounting plate 8 are connected to the connecting shaft 7, the connecting shaft 7 is rotationally connected to the sliding block 6 threadedly connected to the threaded rod 5, the mounting plate 8 is used to connect the solar panel 2, and the protective assembly is arranged on the mounting plate 8. In the face of severe weather such as hail, the motor 4 is started so that its output end drives the threaded rod 5 to rotate, the sliding block 6 on the threaded rod 5 moves vertically along the axis of the threaded rod 5 and drives the mounting plate 8 and the solar panel 2 to move through the connecting shaft 7, so that the mounting plate 8 and the solar panel 2 are closer to the ground to prevent the strong wind from blowing and causing the mounting plate 8 and the solar panel 2 to be deformed and damaged and difficult to unfold.

The steering assembly includes a receiving groove 9, a rack 10 and a gear 11. The sliding block 6 is provided with a receiving groove 9 for slidingly connecting the rack 10. The rack 10 is meshed and connected with the gear 11. The connecting shaft 7 passes through the blind hole on the sliding block 6 and is connected with the gear 11. When the sliding block 6 on the threaded rod 5 moves vertically along the axis of the threaded rod 5, the connecting shaft 7 is driven to move at the same time. The gear 11 on the connecting shaft 7 is meshed with the rack 10 in the receiving groove 9 provided on the sliding block 6. The gear 11 rotates through the connecting shaft 7 to drive the mounting plate 8 and the solar panel 2 to rotate a certain angle to rotate the protective assembly above the mounting plate 8 so that it can protect the mounting plate 8 and the solar panel 2.

The protection assembly includes a first spring 12, a first multi-stage telescopic rod 13 and a protection plate 14.
