Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment protection, and in particular to a new energy photovoltaic battery panel protection device. Background Art

[0002] Photovoltaic panels are devices that use the photoelectric effect to convert solar energy into electrical energy. When sunlight shines on the surface of a photovoltaic panel, the light energy is absorbed by the photovoltaic cells and generates current, but the photovoltaic panel itself is relatively fragile and needs to be protected.

[0003] In recent years, a variety of protective devices for photovoltaic panels have emerged. For example, a Chinese patent with a publication number of CN217406442U discloses a new energy photovoltaic panel protection device, which provides anti-slip grooves and sockets on the surface of the enclosure frame for slidingly adjusting the position of the protection plate and the elastic connecting piece. The protection plate and the elastic connecting piece are stretched and enclosed above the photovoltaic panel to protect the photovoltaic panel.

[0004] However, the device still has certain shortcomings in actual use. In heavy snow weather, the snow will cover the photovoltaic panels. When the photovoltaic panels need to be put into use again, the snow on the protective device needs to be removed so that the photovoltaic panels can be exposed to sunlight to work, which increases the operation and maintenance costs and time costs. In view of this, a new energy photovoltaic panel protection device is proposed. Summary of the invention
