Description
Technical Field
The invention relates to a marine renewable energy power generation technology and a marine industry development technology, in particular to multi-industry fusion floating equipment based on multi-energy complementation.
Background
Along with the prominence of global energy, resources and environmental problems, particularly the global climate change is becoming obvious, the need of accelerating the green low-carbon transformation of energy is urgent, and the ocean energy utilization is coming to develop a trigger. Ocean energy sources include sea wind, waves, solar radiation, and the like. The application of the wind energy is the most mature, the offshore wind energy resource is rich, and the development prospect is wide. The wave motion stores huge energy, has high energy density and wide distribution, is easy to directly use, clean and pollution-free, and is inexhaustible. In addition, compared with land photovoltaic, the offshore photovoltaic land occupies less land, the generated energy is 5% -10% higher, and the reason is that the water surface is wide and free from shielding, the sunlight time is long and the light is reflected by the water surface.
Although ocean renewable energy has infinite prospect, the traditional ocean renewable energy equipment in a single energy form is high in construction and operation and maintenance cost, and the ocean renewable energy is difficult to convey and consume. The development of the emerging ocean industries such as deep-open sea cultivation, offshore hydrogen production, methane and methanol synthesis and the like also faces the problems of insufficient energy supply and unreliable ocean platforms. Therefore, the industry needs to develop multi-production-industry fusion floating equipment based on multi-energy complementation, which has the advantages of simple structure, good wave resistance, high safety, wide applicable water area and good economy, can effectively utilize renewable energy sources at sea, can solve the problems of energy supply and space utilization of the marine industry, and has important significance for more efficient and reasonable development and utilization of marine resources in China.
Disclosure of Invention
The main purpose of the invention is to solve the problems and provide a multi-energy complementary multi-industry fusion floating device.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
The utility model provides a multi-energy complementation-based multi-production fusion floating device which comprises a floating foundation, a large megawatt horizontal axis wind generating set, a tower, a solar photovoltaic panel, an oscillation float type wave energy device, a culture net cage, production and living facilities and a mooring system; the floating foundation is used for supporting the upper structure and comprises rectangular pontoons, bilge keels, main columns, secondary columns, main beams, secondary beams, lower decks, interlayer columns, interlayer beams and upper decks; the bilge keels are arranged on the outer sides of the long sides of the pontoons and far away from the rolling center of the floating foundation; the main upright posts and the secondary upright posts are arranged between the pontoons and the main beams and used for supporting the main beams, the secondary beams are arranged on the upper parts of the main beams, the main beams and the secondary beams form a stable space frame together, and the lower deck is arranged on the upper parts of the space frames; the interlayer column is arranged above the lower deck and used for supporting the interlayer beam, and the upper deck is arranged on the interlayer beam; the large megawatt horizontal axis wind generating set is biased to the midpoint of the short side corresponding to the floating foundation bow through the tower barrel and is used for wind power generation; the solar light Fu Banbu is arranged on the upper deck and is used for photovoltaic power generation; the oscillating floater type wave energy device is arranged between the pontoon and the main beam and is positioned at the periphery of the culture net cage and used for wave energy power generation; the cultivation net cage is arranged below the lower deck, and at least one cultivation space is formed in a hollowed-out area of the floating foundation so as to carry out fishery cultivation; the production and living facilities are positioned on the lower deck; the mooring system is connected to the floating foundation for connecting the floating foundation to the seabed to restrict horizontal movement thereof.
The multi-energy complementation-based multi-industry fusion floating equipment (hereinafter also simply referred to as "floating equipment") of the invention has at least the following beneficial effects:
(1) The floating foundation disclosed by the invention belongs to a semi-submersible foundation, is good in wave resistance, high in safety, wide in applicability, good in economy, large in water depth adaptation range and large in effective load, and because the floating pontoon is similar to a catamaran and has a longer bilge part, the bilge keels arranged on the floating pontoon can reduce the rolling response of floating equipment, and the invention provides a reliable ocean platform.
(2) The floating foundation of the invention has huge space inside, and can carry out deep and open sea fishery cultivation by arranging the cultivation net cage.
(3) The ultra-long space between the pontoon and the main beam of the floating foundation is used for distributing the oscillating floater type wave energy device. The oscillating float type wave energy device can reduce the energy of incident waves and reduce the influence of the waves on the life of fish in the aquaculture net cage when utilizing the wave energy to generate electricity. In addition, the oscillating floater type wave energy device is arranged on the outer side of the culture net cage, so that later maintenance is convenient.
(4) The floating foundation of the present invention has upper and lower decks. The upper deck is used for supporting a plurality of solar photovoltaic panels with light weight to generate solar power, and meanwhile, in the preferable technical scheme, a plurality of satellite antennas are further arranged on the upper deck and used for constructing an offshore communication base station. The lower deck is used as a production and living platform and is matched with production and living facilities, and in the preferable technical scheme, for example, the activities such as fish feeding, fish collecting, sea water desalination, hydrogen production, hydrogen storage, methane-methanol synthesis, offshore communication, environment monitoring, life entertainment and the like can be carried out on the lower deck. In addition, in the preferred technical scheme, a crane and a helicopter apron are also arranged on the lower deck for transferring personnel and materials.
(5) One side of the floating foundation is provided with the large megawatt horizontal axis wind generating set, so that the floating foundation is convenient to install and maintain. In addition, wind power generation can be complementary with solar energy and wave energy power generation to provide energy supply for living facilities.
(6) In the preferred scheme, the fish feeding and collecting module can absorb a large amount of seawater to the lower deck while collecting fish, and the seawater after separating fish can be directly used for hydrogen production by water electrolysis, so that the power consumption of additional water pumping is reduced.
(7) In the preferred scheme, the oxygen generated by the electrolytic hydrogen production system in the chemical energy storage module can be used for oxygenation when the oxygen in the culture net cage is insufficient (such as in overcast, rainy and hot weather), so that the culture loss is reduced.
(8) In the preferred scheme, because the solar photovoltaic panel and the oscillating buoy type wave energy device are smaller than the power generated by a large megawatt horizontal axis wind generating set, the generated electric energy can be used for impressed current cathodic protection of a floating foundation and a mooring system.
