Protection device for solar photovoltaic panel

Abstract

The invention discloses a protection device for a solar photovoltaic panel. The device comprises a machine body. A lifting cavity with an upward opening is formed in the machine body. A sliding cavitypenetrating through the lifting cavity is formed in the top end of the machine body; a sealing mechanism is arranged in the sliding cavity; a solar photovoltaic panel is arranged in the lifting cavity; a cleaning mechanism is arranged above the solar photovoltaic panel; a rotary swinging mechanism is arranged at the lower end of the solar photovoltaic panel. The protection device for the solar photovoltaic panel is simple in structure, full-automatic and rich in function, and is provided with the mechanism capable of rotating and swinging, so that photovoltaic panel can better absorb solar energy, and the efficiency of the photovoltaic panel is improved. The lifting mechanism is arranged. The photovoltaic panel extends into the machine body in rainy days and severe weather, and thus rainwater is prevented from influencing the service life of the photovoltaic panel. In addition, the cleaning mechanism is arranged in the device, so that dust on the surface of the photovoltaic panel canbe swept back and forth to improve the solar energy absorption rate.

Description

technical field [0001] The invention relates to the technical field of solar radiation absorption and utilization, in particular to a protection device for solar photovoltaic panels. Background technique [0002] The energy of solar energy is the energy from celestial bodies outside the earth (mainly solar energy). It is the huge energy released by the fusion of hydrogen nuclei in the sun at ultra-high temperature. Most of the energy needed by human beings comes directly or indirectly from the sun. Solar photovoltaic power generation refers to a power generation method that directly converts light energy into electrical energy without going through a thermal process. Photovoltaic power generation is a direct power generation method that uses solar-grade semiconductor electronic devices to effectively absorb solar radiation energy and convert it into electrical energy. It is the mainstream of solar power generation today. Therefore, the absorption efficiency of solar photovo...

Problems solved by technology

Therefore, the absorption efficiency of solar photovoltaic panels to solar energy directly affects the efficiency of photoelectric conversion. Existing solar photovoltaic panels are exposed to the outside for a long time, and will accumulate a lot of dust for a long time, which is difficult to clean, which will reduce the absorption efficiency of solar energy. At the same time, when the weather is bad , when it rains, if it is not protected, it will have an impact on its lifespan
