Description

technical field

Background technique

Large-scale ground-mounted photovoltaic power plants are generally built on flat or slightly undulating sites, and the corresponding base and support forms are selected according to the geological conditions in the site. However, with the shortage of domestic available land resources and the increasing difficulty of land transfer, at the same time, due to the large construction area required for photovoltaic power stations, the cost of land photovoltaic construction is increasing day by day, and the overall social benefits are decreasing day by day. And most of the water surface is idle.

Therefore, photovoltaic construction sites have begun to develop in water surface areas such as reservoirs, lakes, tidal flats, and fish ponds. However, at this stage, pipe pile bases similar to ordinary ground photovoltaic power stations are still mainly used. The base is buried in the bottom of the water, and the upper part is out of the water for fixing the photovoltaic modules.

However, the stability of such a base is reduced due to the excessive height. At the same time, it is difficult to construct the base of photovoltaic modules in some water areas. The form of the base in different latitudes needs to be adjusted, which is not conducive to the modular construction of photovoltaic power plants on the water surface. It is only suitable for tidal flats, Fishponds and other areas with shallow water levels are not feasible for lakes and reservoirs with large water level changes, so this form of base does not meet the conditions for large-scale application.
