Description
Technical Field
The utility model relates to a complementary and aquaculture field of marine scene especially relates to a floating scene fishing of combining together of vertical axis wind turbine generator system, solar photovoltaic board and aquaculture net case is synthesized and is equipped.
Background
Wind power resources in China are quite rich, and development and utilization of wind energy are important ways for current energy structure adjustment, energy conservation and emission reduction in China and are inevitable choices for future sustainable energy development and economic and social development transformation in China. By the end of 2017, 1503 ten thousand kilowatts of newly-increased grid-connected wind power generation installed in China are added, the accumulated grid-connected installed capacity reaches 1.64 hundred million kilowatts, and the accumulated grid-connected installed capacity accounts for 9.2% of the installed capacity of the national power generation. The annual generated energy of wind power is 3057 hundred million kilowatt hours, which accounts for 4.8 percent of the total generated energy, and the wind power becomes the third largest energy after coal power and water power in China. Along with the gradual reduction of onshore wind power development areas, offshore resources are rich, coastal areas are developed economically, the power grid capacity is larger, wind power access conditions are better, and in recent years, the wind power industry gradually develops from onshore to offshore. The thirteen-five planning of wind power development indicates that the offshore wind power grid-connected installed capacity of China reaches more than 500 ten thousand kilowatts (5GW) by the end of 2020. During the thirteen-five period, China mainly promotes the construction of offshore wind power in Jiangsu, Zhejiang, Fujian, Guangdong and other provinces, and the scale of the construction of the offshore wind power in the four provinces reaches more than million kilowatts; meanwhile, China also can actively promote the construction of offshore wind power in Tianjin, Hebei, Shanghai, Hainan province (city) and the like. With the gradual reduction of the construction cost of offshore wind power, coastal wind power in China is rapidly increasing.
The offshore wind turbine set mainly comprises two types: vertical axis fans and horizontal axis fans. The horizontal shaft fan is applied and developed sufficiently on land and at sea, the technology is relatively mature, and the power generation efficiency is high. But it also presents its own problems: (1) the engine room is at high altitude, the center of gravity is too high, the installation and maintenance are not easy, the cost is high, and the instability is easy to occur; (2) the turning radius is large, and the utilization rate of the wind field is low. The clear distance between two adjacent horizontal axis fans generally needs to reach 5-8 times of the rotation radius, namely 400-800 m. Therefore, the design that a plurality of horizontal axis fans are located on the same net cage is difficult to realize structurally. Compared with a horizontal shaft fan, the vertical shaft wind driven generator is still in a starting stage all over the world, but has the characteristics of strong applicability, stable performance, low gravity center and the like. The vertical axis wind turbine control, transmission and power generation systems are all positioned at the bottom of the fan, the gravity center is concentrated at the bottom of the fan, and the structural stability is better; the equipment has no pitch system and yaw system inherent in a horizontal axis fan, and has low operation and maintenance cost. In addition, the rotating radius of the vertical axis fan is small, so that the idea that a plurality of vertical axis fans share the same floating foundation is possible, and the total power of the vertical axis fan is remarkably larger than that of a single high-power horizontal axis fan.
On the other hand, marine fishery culture in China is rapidly developed and is driven with marine fishing, but the mainstream deep water culture mostly adopts a high-density polyethylene net cage structure, although the net cage is low in cost, the strength is not enough, the applicable water depth is generally not more than 25 meters, the net cage can only be arranged in shallow offshore water, and the net cage is easy to damage under typhoon, so that fishermen are disastrous. In 2017, the first steel semi-submersible aquaculture net cage Ocean Farm in the world is put into operation in Norway, and the deep-sea and large-scale development sequence of fishery aquaculture is formally opened.
The development of marine fishery culture and offshore wind turbines has a common trend at present, namely, the culture goes from shallow sea to deep sea. The cultivation needs to use the deep sea with wide water source as a cultivation base, and the wind power generation needs to be developed with high power by means of stronger and more stable sea wind in the deep and open sea. The solar energy on the sea is also abundant and stable, but is only utilized in a small amount on lakes and offshore banks. Therefore, how to design a device which can efficiently utilize wind, light and water resources on the ocean and integrate the device is a great challenge facing the global engineering world.

The lower half part of the floating offshore wind turbine part adopts a semi-submersible floating platform, the shape of the floating platform is a hexagonal cube, a top panel and a bottom panel of the floating offshore wind turbine part are both made of stainless steel plates, round holes are respectively formed in the centers of the two panels, and then the floating platform is welded with a wind turbine tower barrel, six rectangular stainless steel plates are welded between the top panel and the bottom panel for a circle and are respectively welded with the top panel and the bottom panel, so that a closed space is formed, the floating platform plays a role of a floating drum, and the device can float in water; the bottom structure of the net cage part adopts a double-ring type design, N bottom outer ring transverse metal support rods are welded between a bottom inner ring and a bottom outer ring, the bottom of a fan tower cylinder penetrates through a top panel and a bottom panel of a semi-submersible floating platform, the bottom of the fan tower cylinder is fixedly connected with the N bottom inner ring transverse metal support rods arranged on the bottom inner ring through welding, the N metal support rods are arranged on the bottom panel of the semi-submersible floating platform and are respectively welded on the bottom outer ring, and the peripheries of the N metal support rods are wrapped by aquaculture nets, so that a net cage for actual production is formed; the bottom of the net cage part is welded with N anchor chains and fixed on the seabed; in addition, the bottom of the net cage part is also provided with a cable, one end of the cable is connected with a power generation device in the fan tower cylinder, the other end of the cable is connected with a substation, and electric energy is transmitted to a user after processing.
However, the integrated device disclosed in CN109555650A is designed to integrate a structure of a single vertical axis fan, and does not fully exert the structural advantage of small rotation radius of the vertical axis fan, so that there is great waste to the space above the net cage and the wind field, resulting in low power generation; the disclosed comprehensive device cannot utilize abundant and stable solar energy resources on the sea; the disclosed integrated unit's floating platform is semi-submersible, its structural stability is poor, and motion and damping performance are both poor. Moreover, personnel can't live and carry out activities such as breed, catch, overhaul on this integrated device, and the staff uses and maintains the convenience of this integrated device relatively poor. In addition, the device can only provide a single culture space, the types of the culturable fishes are narrow, and the culture flexibility is poor.
