An integrated device for offshore floating wind turbine and fishery cage culture

Abstract

The invention discloses an offshore floating wind power unit and a fishery net cage culture comprehensive device, which includes a wind power unit, a fan tower, a living platform, a floating fan foundation and a mooring device with a frustum-shaped steel structure from top to bottom; the fan tower The wind turbine is installed at the upper end of the tube, the lower end is fixed on the foundation of the floating wind turbine, and the living platform surrounds the bottom of the wind turbine tower; the mooring device is connected to the foundation of the floating wind turbine, which can moor the comprehensive device on the seabed; it also includes side netting , Bottom netting and lifting device, the side netting is a tensioned netting, which is surrounded and fixed on the side of the foundation of the floating fan, and the lifting device is set in the foundation of the floating fan and connected with the bottom netting to make the bottom netting lift . The present invention utilizes the internal space of the floating fan foundation to form a huge breeding net cage. The net cage is not deformed and has a high degree of automation, which can realize "power generation at the top and fish farming at the bottom". The present invention has good stability and sea resistance, and is suitable for In the middle and deep waters within 200 meters.

Description

technical field [0001] The invention relates to the fields of offshore wind power generation and fishery cage culture, in particular to a comprehensive device for offshore floating wind turbines and fishery cage culture. Background technique [0002] At present, with the increasingly serious problems of land resource shortage, population expansion, and environmental deterioration, coastal countries have turned their attention to the sea and accelerated the development and utilization of the sea. A "blue revolution" marked by the development of oceans has emerged around the world. [0003] As a clean and renewable energy, wind power has developed rapidly. In 2015, the cumulative installed capacity of offshore and land wind power in my country was 145,362MW, accounting for more than 7% of the total installed capacity of electricity, becoming the third largest source of electricity after thermal power and hydropower. Compared with terrestrial wind energy resources, offshore w...

Problems solved by technology

However, the currently used mariculture cages are mainly gravity-type high-density polyethylene cages, which have poor wind and wave resistance in extreme environments such as typhoons, and the nets are easily deformed under the action of waves and currents, making the cages The volume of the breeding is seriously lost, and even the fish escape from the broken net, which brings huge economic losses to the farming

However, the environmental conditions in the deep sea are even harsher, with large waves and rapid currents. This kind of cage cannot adapt to the sea conditions in the deep sea area, which restricts the development of the current aquaculture industry.

Therefore, it is imminent to develop a new type of deep-sea aquaculture net cage, but the problems such as sea resistance of the net cage in the project have not yet been broken through

[0006] In the future, offshore wind farms will choose mid-deep sea areas with open sea areas. If they are only used for offshore wind power generation, marine resources will not be fully utilized, and the payback period for investment will be too long

At the same time, because the deep-sea aquaculture cages are far away from the coastline, the power supply is difficult, which also restricts the development of large-scale and intelligent cage aquaculture.
