Description

TECHNICAL FIELD

[0001] The present application relates to the field of offshore photovoltaic, in particular to an anchoring system and method of a marine photovoltaic floating body. BACKGROUND

[0002] With the development of photovoltaic technology, photovoltaic has been large-scale system in various fields. With the increasingly prominent environmental problems caused by the oil and petrochemical industry, clean and green energy is getting more and more attention.

[0003] With the global development of photovoltaic industry, photovoltaic is given more and more attention because of its low cost and no pollution. The biggest problem of photovoltaic power generation is that it needs to occupy a large amount of land area. The increasingly high land cost may restrict the further development of the photovoltaic industry. On this basis, using the vast sea area to lay photovoltaic equipment for photovoltaic power generation will be a new opportunity for the further development of the photovoltaic industry. Compared with the water surface photovoltaic which has been applied in large reservoirs, lakes and fish ponds, large-scale application of photovoltaic power generation on the sea surface must solve the problem of fixed installation of photovoltaic array and ensure that photovoltaic products can withstand the storm on the sea without being damaged.

[0004] For marine photovoltaic array, anchor ropes or chains should be connected to the hydrofoils around the array, and fixed by sinking into the anchor on the seabed. In actual work, the seabed is uneven, and there is a situation of seabed silt flow, which leads to uneven stress on the pull rope of each hydrofoil, and then after a period of work, part of the pull rope can no longer play the expected role, resulting in unbalanced force provided by the anchoring system. At the same time, under the action of strong wind and sea waves, the photovoltaic array itself is subjected to unstable and unbalanced force, which makes the actual working life of the traditional photovoltaic array generally shorter than three months. In addition, due to the excessive data of counterweight blocks, anchors and other devices in the traditional photovoltaic array anchoring system, the cost is extremely high, and the operation difficulty of arranging photovoltaic array is extremely great. At the same time, too many anchors and other devices will cause a certain degree of interference between adjacent photovoltaic arrays, further affecting the overall working life and arrangement difficulty.

[0005] On this basis, the inventor has made a deep research on marine photovoltaic floating body and its anchoring system, and designed a more simple anchoring system of marine photovoltaic floating body by adjusting the structure of the anchoring system on the premise of ensuring the anchoring firmness according to the physical principle of netting.
