Abstract

The invention discloses a shallow water seaborne floating type fan mooring system. The system comprises a fan, a floating body foundation arranged below the fan and a plurality of mooring structures arranged on the periphery of the floating body foundation, each mooring structure comprises at least one mooring structure unit, each mooring structure unit comprises an anchor chain, a buoy assembly and a plurality of counterweight assemblies, the upper end of the anchor chain is fixedly connected with the floating body foundation, and the lower end is fixed to the seabed; the buoy assembly is fixedly arranged on the anchor chain close to the floating body foundation and used for providing vertically-upward buoyancy for the anchor chain, and the buoyancy is larger than vertically-downward acting force borne by the anchor chain at the position; and each counterweight assembly is fixedly arranged on the anchor chain between the buoy assembly and the lower end of the anchor chain, and is used for providing vertically downward pulling force for the anchor chain. The shape of the anchor chain is changed through a buoy, and the restoring force of the mooring structure is optimized; and meanwhile, the anchor chain is provided with balancing weight, the unit length density of the anchor chain is increased, the catenary effect is improved, the mooring rigidity is improved, the steel consumption and the length of the anchor chain can be reduced, and the manufacturing and construction cost is saved.

Description

Technical field [0001] The present invention relates to the field of maritime wind power generation, and in particular to a shallow water sea floating fan mooring system. Background technique [0002] China's sea wind resources are abundant, and sea wind power development potential is more than 2 billion kilowatts, most of which are in the area of ​​50m water depth. The floating fan is more project economy than the fixed fan compared to the deep sea, and the economic advantage is more highlighted with the water depth. In general, the 40-60M water deep sea area is a shallow water area. my country's existing floating fan demonstration project is basically within the depth of the water depth. [0003] Due to the influence of water depth, the mooring structure of the floating fan is highly difficult in the shallow water environment, which greatly increases the construction cost of the floating fan. In the shallow water environment, the suspension line mooring scheme is too short beca...
