Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation protection, and more particularly, to a photovoltaic power station monitoring and protection system for severe weather. Background Art

[0002] With the continuous development of the economy, humanity's energy consumption is increasing. The vigorous development and utilization of primary energy sources such as oil, coal, and natural gas has not only led to severe depletion of primary energy resources, but also caused environmental damage such as global warming. In particular, the harm caused by the use of primary energy for power generation is gradually outweighing the benefits. Furthermore, due to the recent overcapacity of clean energy sources such as photovoltaic and wind power in my country, energy waste has occurred. Therefore, in recent years, my country has vigorously developed clean energy such as solar energy, converting solar and wind energy into electricity and effectively utilizing clean energy. As a result, an increasing number of photovoltaic and wind power stations have been established.

[0003] The photovoltaic panels of power stations in the existing technology are often installed in open-air environments. In the case of severe weather, the photovoltaic panels may be damaged. Photovoltaic panels are particularly unable to withstand the effects of gravity. For example, in severe weather such as hail attacks, if the photovoltaic panels cannot be folded and stored in time, the hail will damage the photovoltaic panel panels and affect the service life of the photovoltaic panels. The existing technology does not have any protection measures for photovoltaic panels in harsh environments, and cannot automatically activate photovoltaic panel protection measures based on weather changes, which poses certain safety hazards. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a photovoltaic power station monitoring and protection system for severe weather, which can protect the photovoltaic panel group through protective cloth in severe weather, making it less likely for severe weather to cause damage to the photovoltaic panel group.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a photovoltaic power station monitoring and protection system for severe weather, comprising a support plate, which is configured as a square plate;

[0006] Four photovoltaic panel groups are provided, each comprising a backing plate and photovoltaic panels disposed on the backing plate. The photovoltaic panel group is a square panel and its area is one-fourth of the support plate;

[0007] and a protective mechanism for shielding the photovoltaic panel group in severe weather;

[0008] The protection mechanism includes a protective cloth which is unfolded to shield the photovoltaic panel group in bad weather.

[0009] By adopting the above technical solution, when bad weather occurs, the photovoltaic panel group can be shielded by the protective cloth, and the photovoltaic panel group can be protected by shielding, so that the photovoltaic panel group is not easily damaged in bad weather.

[0010] The present invention is further configured such that: during normal power generation, the four photovoltaic panel groups are respectively located at the four corners of the support plate and the four photovoltaic panel groups fully cover the support plate.

When the second photovoltaic panel group slides to the top of the third photovoltaic panel group, the limiting mechanism enables the second photovoltaic panel group to drive the third photovoltaic panel group to slide to the bottom of the fourth photovoltaic panel group.

[0016] By adopting the above technical solution and setting a locking mechanism and a limiting mechanism, the movement of the first photovoltaic panel group can drive the second photovoltaic panel group to be stored at the bottom of the third photovoltaic panel group, and then drive the second photovoltaic panel group and the third photovoltaic panel group to be stored together at the bottom of the fourth photovoltaic panel group.

[0017] The present invention is further configured as follows: the locking mechanism includes at least one electromagnet embedded in the bottom of the second photovoltaic panel group and a metal block capable of being adsorbed by the electromagnet embedded in the top of the first photovoltaic panel group. The metal block corresponds to the electromagnet one by one.
