Description

Technical Field

[0001] The invention belongs to the field of port, coast and offshore engineering and renewable energy utilization, and relates to an ecological dual-purpose coral reef floating breakwater and power generation system suitable for artificial islands. Background Art

[0002] With the development of various projects in the ocean, the demand for artificial islands is increasing, making the construction of artificial islands in full swing. The construction of a large number of artificial islands has caused the original marine landforms to change, which has had a huge impact on the marine ecological environment. Large-scale reclamation activities have brought a series of serious problems to the marine environment, mainly manifested in the decline of fishery resources in coastal waters, the destruction of coastal ecosystems, and the occupation and destruction of feeding grounds, habitats, and spawning grounds for rare marine organisms. But at the same time, with the continuous erosion of artificial islands by waves, artificial islands are also under great threat.

[0003] With the advent of the energy crisis, the increasing depletion of fossil fuels and the greenhouse effect caused by their combustion have had a huge impact on our planet. The development and utilization of renewable energy has become an important way for countries around the world to develop energy strategies and an important direction for implementing sustainable development strategies. Compared with renewable energy sources such as biomass energy, "solar energy", "wave energy", "tidal energy" and "ocean current energy", wind power technology is more mature and has lower costs, especially at sea, which has abundant wind energy resources. Therefore, the development of the offshore wind power industry has been favored by many coastal countries. At this stage, offshore wind power technology has gradually matured. my country has successively issued a series of relevant policies and plans, increased research on offshore wind power technology, and greatly promoted the development of offshore wind power technology. Summary of the invention

[0004] In order to improve the energy supply, ecology and wave erosion problems of artificial islands, the present invention provides an ecological dual-purpose coral reef floating breakwater and power generation system suitable for artificial islands.

[0005] The technical solution of the present invention:

[0006] An ecological dual-purpose coral reef floating breakwater and power generation system suitable for artificial islands, including a wind power supply system and an ecological coral reef cultivation system 1005;

[0007] The wind power supply system includes a current conversion station 1001 and a plurality of monopile wind turbines 2001; the bottom of the monopile wind turbine 2001 is fixed on the seabed; the current conversion station 1001 is located on the shore, and the electric energy generated by the monopile wind turbine 2001 is transmitted to the required area through the current conversion station 1001;

[0008] The ecological coral reef cultivation system 1005 is located on the seabed, and includes a plurality of spherical reef bases 2002, cultivation connection devices 2003 and corals 2004; the spherical reef bases 2002 include a reef base body 3000 and a coral reef; the reef base body 3000 includes a reef anchoring cover 3002 and a connector 3001, the reef anchoring cover 3002 is a spherical table shape that is narrow at the top and wide at the bottom and hollow inside, and serves as a coral reef transplant base. It has a mounting hole symmetrically arranged at the top and bottom, and a plurality of holes opened on the side, and the coral reef is placed in the reef anchoring cover 3002; the connector 3001 includes a connecting column 4001 and a connecting ring 4002, and the connecting column 4001 is vertically fixed to the reef base body 30 00, the connection ring 4002 is welded to the top of the connection column 4001; the bottom of the monopile wind turbine 2001 is equipped with a spherical reef base 2002, and multiple spherical reef bases 2002 are arranged between adjacent monopile wind turbines 2001, and all spherical reef bases 2002 are fixed to the seabed through anchor cables; the cultivation connection device 2003 is a rod-shaped structure, which is fixed to the spherical reef base 2002 equipped on the monopile wind turbine 2001 through the connection ring 4002, and the spherical reef base 2002 equipped on the monopile wind turbine 2001 is connected as a whole to form a mesh structure, and corals 2004 are placed in the gaps between four adjacent monopile wind turbines 2001;

[0009] In the early stage of coral reef cultivation, the spherical reef base 2002 is completely fixed on the seabed. After the cultivation is completed, the anchor cable is loosened to make the spherical reef base 2002 float on the sea surface to form a floating breakwater.

[0010] The installation method and functions of each component system are as follows: monopile wind turbines are installed around the island and connected to the artificial island through circuits to provide the energy needed on the island; part of the spherical reef base in the ecological coral reef cultivation system is anchored to the seabed by anchor cables, and part relies on monopile wind turbines and anchor cables to anchor to the seabed; multiple spherical reef bases are connected through cultivation connection devices and monopile wind turbines to provide a place for rapid reproduction for corals to attach and form stable artificial reefs; as the corals grow subsequently, the spherical reef base is raised to the sea level by artificially controlling the anchor cables, and finally floats on the sea surface to form a large-scale coral reef floating breakwater.

[0011] Beneficial effects of the present invention: The present invention can make the artificial island at sea realize energy self-sufficiency while repairing the island ecosystem to prevent the construction of the artificial island from damaging the marine ecological environment. The wind turbines built around the artificial island convert wind energy into electrical energy, realizing the power self-sufficiency of the artificial island and solving the problem of stable power supply when the artificial island is off the grid; since the original ecological environment of the ocean will be destroyed in the early stage of the establishment of the artificial island, the spherical reef foundation is used to cultivate coral reefs on the seabed in the early stage of the establishment of the artificial island, and the spherical reef is fixed with an anchor cable. After the spherical reef matures, the anchor cable is controlled to make the spherical reef float to the surface and surround the island. The spherical reef surrounds the floating island, which can eliminate waves, provide a calm sea surface for the artificial island to dock ships, and can also weaken the scouring of the island by waves. At the same time, the spherical reef base provides a fixed place for the rapid reproduction of corals to stabilize the artificial reef body, while also taking into account the function of artificial fish reefs, thus integrating the three functions of artificial fixed reefs, asexual coral cultivation, and artificial fish reefs in one; while cultivating the spherical reef base, a compound breakwater is built, which integrates ecology and protection. The purpose is to provide a sealed environment for the seaport together with the spherical reef base. Under the dual effects of the spherical reef and the breakwater, it can not only restore the ecological environment, but also prevent the erosion of waves. Especially in sea areas strongly affected by monsoons, frequent typhoon disasters, and strong human interference, it can weaken the damage of waves and storm surges around the artificial island, improve biodiversity, restore the ecological balance, and is conducive to the stability and sustainable development of the ecological environment around the artificial island at sea.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0020] The present invention provides an artificial island ecological breakwater combining an island wind turbine group and an artificial coral reef. The monopile wind turbine is fixed in the sea area around the island and connected to the current conversion station on the island through a circuit to supply electricity to various power consumption areas. The monopile wind turbine is fixed to the ecological coral reef cultivation system, and after the coral reef grows and develops completely, part of the spherical reef base in the ecological coral reef cultivation system is floated to form an ecological coral reef wave-breaking system.

[0021] like Figure 1 As shown, the system of the present invention is mainly composed of a wind farm and an ecological coral reef cultivation system 1005, and can also be provided with an island freshwater system 1002, a port 1004 and an airport 1003. The wind farm is composed of two parts: land wind power generation and offshore wind power generation. The abundant wind energy in the sea area is converted into electric energy and transmitted to the current conversion station 1001 through the circuit. The current conversion station 1001 is used to output unstable wind power as stable and controllable electric energy and transmit it to various areas. The single pile wind turbine 2001 is fixed on the seabed. The island freshwater system 1002 uses the electric energy generated by the wind farm to purify seawater, and generates a large amount of superheated steam by heating the seawater in the later stage to drive the steam turbine in the system to generate electricity, output stable and controllable power electric energy, realize waste heat utilization, and improve energy utilization.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the ecological coral reef cultivation system 1005 is mainly composed of a plurality of spherical reef bases 2002, a cultivation connection device 2003 and corals 2004. The spherical reef base 2002 is mainly composed of a reef base body 3000 and a coral reef. The reef base body 3000 includes a reef anchor cover 3002 and a connection piece 3001. The reef anchor cover 3002 is a spherical table shape that is narrow at the top and wide at the bottom and hollow inside. It is mounted on the monopile wind turbine 1002 through the mounting hole in the middle, and the coral reef is placed in the reef anchor cover 3002; the connection piece 3001 includes a connection column 4001 and a connection ring 4002. The connection column 4001 is fixed on the top of the reef base body 3000, and the connection ring 4002 is welded to the top of the connection column 4001; the bottom of the monopile wind turbine 2001 is equipped with a spherical reef base 2002, and the adjacent monopile wind turbine 200 1 are also arranged with a plurality of spherical reef bases 2002, all of which are fixed to the seabed by anchor cables; the cultivation connection device 2003 is a rod-shaped structure, which is fixed to the spherical reef base 2002 mounted on the monopile wind turbine 2001 by a connecting ring 4002, and the spherical reef base 2002 mounted on the monopile wind turbine 2001 are connected as a whole to form a mesh structure, and corals 2004 are placed in the gaps between four adjacent monopile wind turbines 2001 to form an ecological coral reef, which provides a place for rapid reproduction for corals to attach and form stable artificial reefs, and can also play a repairing effect on the coral reefs near the artificial island that have suffered human ecological damage.

[0023] like Figure 5 As shown, based on the monopile wind turbine 2001, the spherical reef base 2002 is anchored to the bottom of the seabed by anchor cables to carry out coral reef cultivation. Figure 6 As shown, when the coral reef is fully cultivated, the spherical reef base 2002 is raised by controlling the anchor cable to form a floating breakwater for wave protection.

[0024] The construction method of an ecological dual-purpose coral reef floating breakwater and power generation system suitable for artificial islands in this embodiment is as follows:

[0025] 1. When constructing a wind farm in a suitable sea area near the artificial island, a corresponding ecological coral reef cultivation system 1005 and anchor cables should be reserved.

[0026] 2. Complete the construction of the wind power plant, the current conversion station 1001, the island fresh water system 1002, the port 1004 and the airport 1003, lay cables to connect the wind farm and the current conversion station 1001, provide electricity to operate the island fresh water system 1002, and ensure the energy supply on the island, thereby meeting the production and living needs.

[0027] 3. Based on the single pile wind turbine 2001, the spherical reef base 2002 is connected by the connector 3001 to provide a development place for corals. When the coral reef is fully developed, the reserved anchor cable rises to expose the coral reef to the sea surface, forming an ecological breakwater. At the same time, the coral reef group can play an important role in soil and water conservation on the island, and enhance the stability and disaster resistance of the artificial island.

[0028] The present invention has the following advantages:

[0029] 1. By using monopile wind turbines as pillars to build ecological coral reefs, the built coral reefs can not only purify the surrounding seawater environment, restore the previous marine ecological appearance, attract a large number of fish to increase the ecological diversity of the island, but also weaken waves and storm surges, and reduce erosion and disasters on the island.

[0030] 2. After the ecological coral reefs are cultivated, the spherical reef base fixed to the seabed will be untied and controlled by anchor cables to float on the water to form a floating breakwater, which will work together with the coral reefs to reduce the erosion of the artificial island by waves.

[0031] 3. The floating breakwater formed can provide the island with a spacious flat sea surface for docking ships.
