A sea surface photovoltaic platform and its power generation working method and cleaning method

Abstract

The invention relates to an offshore high-efficiency photovoltaic platform, and a power generation working method and cleaning method thereof. The high-efficiency photovoltaic platform is formed by mutual connection of a plurality of single platform bodies. The single platform bodies consist of floating parts and bowl type support platforms arranged above the floating parts; and the bowl openings of the support platforms are arranged upwardly and can deform by external forces. A plurality of grooves are formed in the upper surfaces of the support platforms; and photovoltaic panels are embedded in the grooves. Connection parts between the photovoltaic panels and the support platforms are point connection. Annular electrostriction loops are embedded along the external circumferences of the support platforms and are controlled by a control circuit to extend / Besides, annular outlet grooves are formed along the external circumferences of the support platforms and the openings of the outlet grooves face the insides of the support platforms; the outlet grooves and a fresh water chamber are communicated; and a water pump pumps fresh water in the fresh water chamber out of the outlet grooves to clear the photovoltaic panel, so that corrosion of salt in air on the photovoltaic panel can be reduced. And the efficiency for solar energy utilization can be improved effectively.

Description

technical field [0001] The invention relates to a sea-surface photovoltaic platform, a power generation working method and a cleaning method thereof, and belongs to the field of water power generation. Background technique [0002] In modern times, due to the extensive application of fossil fuels, the earth's ecological environment has suffered serious damage, the greenhouse effect has become more and more serious, and fossil fuels are non-renewable energy sources, human beings need more environmentally friendly and renewable new energy sources, and solar energy is the best choice for people. As the population continues to grow, the available land area is getting smaller and smaller, and the use of solar energy requires a lot of space. Therefore, the vast and uninhabited sea is undoubtedly the best place for solar power generation.

[0002] In modern times, due to the extensive application of fossil fuels, the earth's ecological environment has suffered serious damage, the greenhouse effect has become more and more serious, and fossil fuels are non-renewable energy sources, human beings need more environmentally friendly and renewable new energy sources, and solar energy is the best choice for people. As the population continues to grow, the available land area is getting smaller and smaller, and the use of solar energy requires a lot of space. Therefore, the vast and uninhabited sea is undoubtedly the best place for solar power generation. The existing offshore photovoltaic The power generation platform is relatively mature, but the utilization rate of light energy is low, and photovoltaic power generation equipment is also vulnerable to salt corrosion in the air, resulting in short life of photovoltaic power generation equipment and high long-term cost of photovoltaic power generation on water, which has become a constraint for the development of photovoltaic power generation industry on water a major factor
