In addition, existing wind power generation and submarine hydropower generation equipment have the following problems: (1) The center of gravity is too high.
[0003] (2) Due to the intermittent nature of wind power generation and hydropower generation, the capacity of cables and substations cannot be used efficiently when they are constructed separately.
[0004] (3) Submarine hydropower generation currently has a small power generation capacity and requires standalone construction. The supporting construction requires a large amount of cables and does not have a competitive advantage.
[0005] (4) Submarine hydroelectric power generation equipment cannot automatically adjust its direction according to the direction of water flow, and its utilization hours are relatively low.
[0006] (5) Submarine hydroelectric power generation equipment is more difficult to generate electricity than offshore wind power, and has a greater impact on surrounding ships and other dangerous objects.
[0007] (6) Undersea hydroelectric power generation equipment is difficult to inspect, repair and maintain.
[0008] (7) Submarine hydroelectric power generation equipment is located near the seabed. Due to the resistance of the seabed, the water flow is low, the power generation capacity is low, and the utilization hours are low.
[0009] (8) Submarine hydroelectric power generation equipment is located near the seabed, where there is a lot of sand and debris, which affects the service life of the equipment.
[0010] To this end, the present application designs a deep-water semi-submersible wind power generation coupling direction automatically adjustable hydropower generation system and solves the above-mentioned problems. Summary of the invention
[0011] In order to make up for the deficiencies in the prior art, the present invention provides a deep-water semi-submersible wind power generation coupling direction automatically adjustable hydropower generation system.
[0012] A deep-water semi-submersible wind power generation coupling direction automatically adjustable hydraulic power generation system, comprising a semi-submersible wind power generation foundation part, characterized in that: A wind turbine is connected to the top of the semi-submersible wind power generation foundation part, the semi-submersible wind power generation foundation part is fixedly connected to the semi-submersible wind power generation foundation floating body, and a seabed hydroelectric generator is rotatably connected to the bottom of the semi-submersible wind power generation foundation part.
[0013] Furthermore, in order to better realize the present invention, the bottom center of the semi-submersible wind power generation foundation part is connected to a rotating device at the connection between the submarine hydroelectric generator and the semi-submersible wind power generation tower, and the bottom of the rotating device at the connection between the submarine hydroelectric generator and the semi-submersible wind power generation tower is connected to the submarine hydroelectric generator.
[0014] Furthermore, in order to better implement the present invention, a submarine hydroelectric generator micro-water wheel is connected to the tail of the submarine hydroelectric generator rotor of the submarine hydroelectric generator, which can automatically change the direction of the submarine hydroelectric generator under the influence of water flow.
[0015] Furthermore, in order to better realize the present invention, the semi-submersible wind power generation foundation buoy is fixedly connected to the periphery of the semi-submersible wind power generation foundation part, and the semi-submersible wind power generation foundation buoy is also connected to the semi-submersible wind power generation foundation steel structure of the semi-submersible wind power generation foundation part.
[0016] Furthermore, in order to better implement the present invention, a float zipper is connected to the bottom of the semi-submersible wind power generation foundation float.
[0017] The beneficial effects of the present invention are: The present invention couples wind power generation and hydropower generation, and can effectively utilize existing investments such as the foundation, cables, booster stations, and transmission lines of existing wind turbines. When the technical parameters are appropriately adjusted, hydropower generation equipment can be added. This technology reduces unit construction costs, reduces total cable length, and reduces total booster station investment costs. Because a hydropower generator is set at the bottom of the wind turbine foundation, the center of gravity is moved downward, which increases the structural safety and stability of the power generation system. The hydropower generator of the invention is provided with a micro-water wheel at the extension of the large water wheel rotor. The micro-water wheel is affected by the water flow and can automatically change the direction of the hydropower generator set to ensure that it faces the water flow direction, has direction adjustability, and increases the utilization hours of submarine hydropower equipment. The invention not only effectively saves construction investment, but also effectively increases the utilization hours of submarine hydropower generators, increases the total utilization hours of the power generation system, and improves the internal rate of return of the project. The hydropower equipment is close to the sea level, and the water flow speed is higher than the seabed, which can increase the power and utilization hours of the equipment, is less affected by sand and debris on the seabed, and has a long service life.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.
[0022] Figure 1-Figure 2 This is a specific embodiment of the present invention, which is a deep-water semi-submersible wind power generation coupling direction automatically adjustable hydropower generation system, comprising a semi-submersible wind power generation foundation part 2, a semi-submersible wind power generation foundation buoy 3, a semi-submersible wind power generation foundation steel structure 4, a semi-submersible wind power generation foundation buoy bottom 5, a buoy zipper 10, etc.
[0023] A rotating device 6 for connecting the submarine hydroelectric generator and the semi-submersible wind power tower is provided at the bottom of the semi-submersible wind power generation foundation 2, and a submarine hydroelectric generator 7 is connected below. This embodiment increases the power generation of the deep-water semi-submersible wind power generation coupling direction automatically adjustable hydroelectric power generation system 1, and reduces the investment amount per kilowatt.
[0024] By adding the submarine hydroelectric generator 7, the center of gravity of the deepwater semi-submersible wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 is effectively lowered, and the stability of the deepwater semi-submersible wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 is improved.
[0025] When the water flows through the submarine hydroelectric generator blades 8, it drives the submarine hydroelectric generator rotor 9 to rotate and generate electricity. The submarine hydroelectric generator micro-water wheel 11 is at the tail of the submarine hydroelectric generator rotor 9. Its main function is to be affected by the water flow and automatically change the direction of the submarine hydroelectric generator 7 to ensure that the submarine hydroelectric generator 7 faces the direction of the water flow. It has direction adjustability and increases the utilization hours of the submarine hydroelectric power generation equipment. The submarine hydroelectric generator micro-water wheel 11 can also provide partial power to increase the power of the submarine hydroelectric generator 7.
[0026] The submarine hydroelectric generator 7 is at a certain distance from the seabed, and the seawater flow rate is greater than the seawater flow rate at the seabed, which can increase the power of the submarine hydroelectric generator 7. In addition, the submarine hydroelectric generator 7 is at a certain distance from the seabed to avoid the influence of seabed sand and stone, and improve the system life.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
