Marine floating type wind generating set and fishery cage culture comprehensive device

Abstract

The invention discloses a marine floating type wind generating set and fishery cage culture comprehensive device. The marine floating type wind generating set and fishery cage culture comprehensive device comprises a wind generating set, a wind turbine tower cylinder, an accommodation platform, a floating type wind turbine foundation in a cone-frustum-shaped steel structure and a mooring device from top to bottom; the wind generating set is mounted at the upper end of the wind turbine tower cylinder, the lower end of the wind turbine tower cylinder is fixed to the floating type wind turbine foundation, and the accommodation platform surrounds the bottom of the wind turbine tower cylinder; the mooring device is connected to the floating type wind turbine foundation and can moor the comprehensive device to a seabed; and the marine floating type wind generating set and fishery cage culture comprehensive device further comprises side face netting, bottom face netting and a lifting device;the side face netting is in a tensioning type and is fixed to the side face of the floating type wind turbine foundation in an encircling mode; and the lifting device is arranged in the floating typewind turbine foundation and connected with the bottom face netting to enable the bottom face netting to rise and fall. A huge culture cage is formed in the internal space of the floating type wind turbine foundation, the cage does not deform, the automation degree is high, and the effects of power generation on the upper portion and fish-farming on the lower portion can be achieved; and the marinefloating type wind generating set and fishery cage culture comprehensive device has good stability and seakeeping performance and is suitable for medium-depth water sea areas with the depth being within 200 m.

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.
