Description

A floating body of a water surface photovoltaic power station

technical field

The utility model belongs to the technical field of solar energy, in particular to a floating body of a water surface photovoltaic power station.

Background technique

With the depletion of traditional energy, the development of new energy utilization technology is changing with each passing day. In particular, the distribution and use of photovoltaic power stations will play a more important role. In economically developed regions such as the Yangtze River Delta and the Areas with dense river networks and relatively scarce land resources. Therefore, in such an uncoordinated situation, priority can be given to the construction of distributed power stations for reasonable adjustments to promote a reasonable balance of electricity consumption in the region.

The construction of traditional surface photovoltaic power stations mostly adopts surface piling or buoy type. In order to ensure that the battery components are not soaked by river water, the elevation of pile tops for surface piling is usually higher than the highest water level in the wet season. High, causing inconvenience to installation, on the other hand, the pile foundation can only be used when there is no anti-seepage layer underwater, making it more difficult to build a power station on the water surface; while the traditional buoy-type water surface photovoltaic power station usually consists of beams, vertical poles, slanting poles, photovoltaic Modules (solar panels), U-shaped bolts, and buoys are assembled. The installation process is complex and complicated, with low installation efficiency and high procurement costs.

The disadvantage of this structure is that the installation size between the buoy and the photovoltaic module is single, which cannot guarantee the safety performance of the surface power station and the applicability of the buoy to the battery module to the greatest extent. Moreover, in order to further reduce the cost of solar cell components, various cell component manufacturers continue to introduce new specifications of cell components, and there are also certain differences in external dimensions, which makes it impossible to use a single installation size buoy to meet market demand. , there are many restrictive factors in the process of use.
