[0002] Traditional solar photovoltaic power stations are mainly installed on land, and distributed power stations are installed on roofs. With the rapid expansion of photovoltaic solar installation capacity in recent years, land has become a scarce resource; the resources of rooftop power stations have also become scarce, and most roofs need to be reinforced to meet the construction and installation requirements of photovoltaic solar power stations. In the case of scarce installation site resources, solar photovoltaic water surface power stations have appeared on the market, which can not only solve the shortage of current resources, but also save precious land resources by rationally utilizing idle water surfaces. However, photovoltaic solar water surface power stations generally have the following shortcomings: the water surface installation bracket and supporting floating system are relatively complex, the material cost is high, the installation is difficult, and the reliability of use after installation cannot be guaranteed; the existing photovoltaic components and structures are designed according to ground photovoltaic power stations, and they are fixed when installed on photovoltaic brackets. Whether in terms of the structure of the photovoltaic components or the installation and fixing method, it is difficult to apply to the installation environment of floating on the water surface. If installed on the sea surface, the existing sea surface floating component installation has the following shortcomings: the floating buoy is assembled into a whole, cannot be disassembled, has no flexibility, is difficult to maintain, and has high costs; there are no facilities around to buffer the impact of wind and waves.
