Elevated net box based on composite drum-type foundation of offshore wind turbine

Abstract

The invention relates to an elevated net box based on a composite drum-type foundation of an offshore wind turbine. The net box comprises a cylindrical composite drum-type foundation base, a wind driven generator foundation pillar, a cultivation net box and a support rack. The foundation base is built on a seabed. The foundation pillar is built on the base. The support frame is fixedly installed on the wind driven generator foundation pillar. Multiple vertical guide cables are arranged between the support frame and the cylindrical composite drum-type foundation base along the peripheral direction. The cultivation net box can be slidably sleeved on the wind driven generator foundation pillar up and down and is located below the support rack. The side surface of the cultivation net box is connected with the guide cables. The wind driven generator foundation pillar is provided with a traction device. The cultivation net box is pulled by the traction device to move up and down along the wind driven generator foundation pillar. The elevated net box based on the composite drum-type foundation of the offshore wind turbine has the following beneficial effects: an elevated net box facility is combined with a composite drum-type wind generator on the sea, the resistance to sea wind, waves and flows of the net box can be improved, especially the resistance to typhoon; construction cost is lowered; benefit is increased; damage to the structural stability is reduced; and volumetric ratio of the net box is kept.

Description

technical field [0001] The invention belongs to the technical field of wind power generation and sea farming, and in particular relates to a lift-type net cage based on a composite cylindrical foundation of an offshore fan. Background technique [0002] Under the increasingly severe resource situation, all countries have turned their attention to the sea area. The huge seawater wind resources, good fish, shellfish and other aquaculture water resources and environment have made offshore wind power generation, marine aquaculture and other industries flourish. [0003] The wind speed of offshore wind farms is higher than that of land wind farms, but the infrastructure investment cost of offshore wind power generation is higher than that of land wind farms, and the capital recovery is relatively slow. Mariculture often adopts cage culture, which usually requires a large cost for the construction of an ideal breeding place and the infrastructure of the cage; in addition, the cult...

Problems solved by technology

Mariculture often adopts cage culture, which usually requires a large cost for the construction of an ideal breeding site and the infrastructure of the cage; in addition, the culture of traditional seawater cages, due to its cage structure, materials and anchoring technologies Due to the limitation, especially in the open sea far away from the land coastline, it is easy to damage the cages and cause the loss of breeding if it is harassed by wind and waves, especially typhoons.
