Comprehensive structure of semi-submersible offshore wind power and aquaculture fishery platform

Abstract

The invention discloses a comprehensive structure of semi-submersible offshore wind power and an aquaculture fishery platform. The comprehensive structure comprises a draught fan and a fishery platform arranged at the bottom of the drought fan, the fishery platform comprises a semi-submersible frame, the semi-submersible frame is a cuboid, the semi-submersible frame comprises four vertically arranged pontoons, transverse supporting and diagonal supporting for connecting the pontoons, and netting is fixed to the side wall and the bottom of the semi-submersible frame; and mooring cables are fixed to the bottom of the pontoons, and the bottoms of the mooring cables are fixedly connected with anchors arranged on seabed. According to the comprehensive structure of the semi-submersible offshorewind power and the aquaculture fishery platform, the offshore wind power technology and the deep sea aquaculture equipment technology are integrated, the offshore wind power is directly used in electrical equipment of the fishery platform, the cost of long-distance transmission is saved, a new way is also provided for offshore wind power resources, and the problem of difficult to balance the offshore wind power and terrestrial thermal power is eased.

Description

technical field [0001] The invention relates to a farming fish farm platform, in particular to a comprehensive structure of a semi-submersible offshore wind power and farming fish farm platform. Background technique [0002] At present, the total wind energy reserves that can be developed and utilized in my country are about 1 billion kilowatts. However, most of the offshore wind farms that have been built or are under construction in my country are located in offshore waters with a water depth of about 30 meters. With the increasing emphasis on environmental protection in coastal areas and the impact on marine farming and shipping traffic, the site selection of wind farms in shallow waters near the coast will be subject to stricter restrictions. It is an inevitable trend for future offshore wind power development to gradually move towards deep sea and far shore . Considering the cost and benefit of deep-sea wind energy development, the transformation of the lower support s...

Problems solved by technology

[0004] Disadvantages of deep-sea wind power technology: it is difficult to transmit long-distance wind power from deep-sea wind power to land, the cost is high, and the loss is large; the balance between offshore wind power and land thermal power is still difficult

[0005] Technical defects of deep-sea aquaculture equipment: The automation equipment for deep-sea fishery platforms requires continuous and stable power supply. Laying submarine cables from land or simply using diesel generators cannot completely solve the problem of energy supply for deep-sea aquaculture facilities and equipment; The anti-wind and wave ability of the fishing ground platform is relatively high, the design and construction of the mooring system are difficult, and the overall cost is high. It is difficult to quickly recover the cost simply by breeding
