However, the main parts of the device are connected through a hinge mechanism, and under extreme sea conditions, the parts are easy to move excessively relative to each other to cause the loss of a hinge area, so that the device is disassembled. The offshore floating type photovoltaic system comprises a flexible floating photovoltaic platform and a plurality of groups of mooring units, wherein the flexible floating photovoltaic platform comprises a floating net, a buoyancy unit and a risk avoiding device; wherein the mooring unit is used for fixing and unfolding the flexible floating photovoltaic platform; the floating net is used for installing the photovoltaic panel; the buoyancy unit provides buoyancy; the risk avoiding device is externally connected with the waterway system and the gas circuit system, and drives the platform to float or dive to cope with different sea conditions by adjusting the water-air ratio.
