Solar energy generating water special-purpose platform

Abstract

The invention relates to a water platform specially used for solar power generation, which is a water platform of a floating type or bed rest type fixed structure with solar electricity-heat hybrid collector; the electricity-heat hybrid collector of glass tube structure is provided with a cooling circulatory system; the solar electricity-heat hybrid collector is connected on an installation plane which is higher than the height of water wave in a matrix and facing the reflecting direction of the sunlight, so as to directly supply power after net incorporation and connection of a control device and an inverter into the land grid, or store energy and supply power after connection with the accumulated battery set. The water platform specially used for solar power generation adopted greatly reduces the wind load, improves the anti-wind-wave stability, reduces the weight and greatly reduces the building and maintaining cost; and can be arranged on the shallow beach water near areas on rivers, lakes and seas to reduce the electricity consumption of the power transmission and transformation circuits, with far wider scope of construction than the prior art.

Description

Technical field [0001] The invention relates to a solar energy utilization technology, in particular to a special platform for solar power generation on the water. Background of the invention [0002] Most power shortages in the world often occur in marginal areas where the economy is relatively backward or in coastal areas where the economy is highly developed. In order to solve the lack of electricity in the fringe areas, solutions such as the establishment of independent photovoltaic power stations in remote mountainous areas, small household rooftop photovoltaic modules, and small and medium-sized commercial rooftop light photovoltaic modules can be adopted. However, it is necessary to solve the problem of high economic development such as the lack of electricity in coastal areas. The establishment of a renewable energy alternative to conventional energy generation requires a larger area and scale of solar power plant components. Therefore, some people have proposed a technic...

Problems solved by technology

In order to solve the power shortage in marginal areas, solutions such as the establishment of independent photovoltaic power stations in remote mountainous areas, small household rooftop photovoltaic modules, and small and medium-sized commercial rooftop photovoltaic modules can be adopted. The establishment of renewable energy alternatives to conventional energy generation requires large-scale and large-scale solar power plant components. Therefore, some people have proposed a technical solution for building large-scale solar power plants in desert sunny areas. This technical solution exists The problem is that desert solar farms are far away from most of the coastal areas that need power supply. The pipelines that transmit electric energy through solar farms have a large loss, and the power grid expansion project requires a large amount of transformation. Moreover, solar farms are affected by harsh environmental factors such as sandstorms and high temperatures in the desert. The impact and interference of large-scale desert solar power plants are too high, making the cost of building large-scale desert solar power plants and the cost of use and maintenance extremely high, or the conditions suitable for building large-scale desert solar power plants are greatly restricted

[0003] The existing floating platform with solar power generation function makes it difficult to balance its anti-wind and wave performance and cost due to structural technical reasons. In order to improve the anti-wind and wave performance of the floating platform, it often adopts huge volume and weight. Functional platform", due to its huge underwater balance structure and platform weight, the income from its solar power generation function is not proportional to the construction and maintenance costs of the water platform, so it can only be used in areas with large water depths, and its application range is limited. In addition, Due to the installation position and direction of the solar photovoltaic power generation device and the way of power supply, it cannot meet the actual requirements of maximizing the efficiency of solar power generation. Therefore, a more advanced improvement technology for solar power generation and power transmission using a special platform on the water is needed.
