The invention relates to the technical field of photovoltaic equipment, and discloses a cable-supported marine photovoltaic
floating system, which comprises floating units, a
cable net structure, a frame structure and a
mooring structure, the
cable net structure comprises longitudinal cables and transverse cables, the longitudinal cables and the transverse cables intersect to form a grid shape, and the longitudinal cables and the transverse cables intersect and are fixed in the floating units; the outer ends of the longitudinal cables and the outer ends of the transverse cables are connected with the frame structure, the frame structure is connected with the
mooring structure, and the
mooring structure is used for keeping pretension of the transverse cables and the longitudinal cables. According to the scheme, the longitudinal cables and the transverse cables are stressed in a face mode, a traditional point
stress mode is replaced, external force can be dispersed more evenly, the local damage risk is reduced, and high
fatigue resistance is achieved; the longitudinal cables and the transverse cables are fixed through the floating units,
relative displacement of the longitudinal cables and the transverse cables is avoided, the integrity of the
cable net structure is guaranteed, the frame structure and the mooring structure fluctuate up and down along with stormy
waves and adapt to dynamic changes of the cable net structure, and the stability and durability of the whole floating type offshore
photovoltaic system in the complex marine environment are guaranteed.
