Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power generation equipment, and in particular to a pipe frame type wind power generation coupling direction automatically adjustable hydraulic power generation system. Background Art
[0002] Existing wind turbines with jackets only have a single type of power generation equipment, wind power generation, which uses wind energy to generate electricity, and submarine hydroelectric generators that use tidal energy and ocean current energy to generate hydroelectric power. Under existing technical conditions, separate investment in wind power generation and submarine hydroelectric power generation both face the problem of high investment cost per unit installed capacity. The current power generation equipment of this type has the following problems: (1) In order to lower the center of gravity, the amount of steel used in the foundation of the jacket-type wind turbine generator set is relatively large.
[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 detect than offshore wind power and poses a greater risk to surrounding ships.
[0007] (6) Undersea hydroelectric power generation equipment is difficult to inspect, repair and maintain.
[0008] To this end, the present application designs a jacket-type wind power generation coupling direction automatically adjustable hydropower generation system and solves the above-mentioned problems. Summary of the invention
[0009] In order to make up for the deficiencies in the prior art, the present invention provides a jacket-type wind power generation coupling direction automatically adjustable hydropower generation system.
[0010] A jacket-type wind power generation coupling direction automatically adjustable hydropower generation system, comprising a jacket foundation, characterized in that: A rotatable submarine hydroelectric generator is installed above the jacket foundation, a jacket is installed above the submarine hydroelectric generator, and a wind turbine tower and a transition zone are installed on the jacket.
[0011] Furthermore, in order to better realize the present invention, the submarine hydroelectric generator is installed between the upper layer of the submarine hydroelectric generator and the lower layer of the submarine hydroelectric generator, the upper layer of the submarine hydroelectric generator is connected to the bottom of the conductor frame, and the lower layer of the submarine hydroelectric generator is connected to the upper part of the conductor frame foundation.
[0012] Furthermore, in order to better implement the present invention, a rotating shaft is rotatably connected between the upper layer of the submarine hydroelectric generator and the lower layer of the submarine hydroelectric generator, and the submarine hydroelectric generator is fixedly connected to the rotating shaft.
[0013] 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.
[0014] Furthermore, in order to better realize the present invention, the micro-water wheel of the submarine hydroelectric generator is affected by the water flow and can drive the submarine hydroelectric generator to rotate so that it faces the direction of the water flow.
[0015] The beneficial effects of the present invention are: The present invention couples wind power generation and hydropower generation, and can effectively utilize the existing investments of existing wind turbines such as the pipe frame foundation, cables, booster stations, and transmission lines. When the technical parameters are appropriately adjusted, hydropower generation equipment can be added. This technology reduces the unit construction cost, reduces the total cable length, and reduces the total booster station investment cost. Because a hydroelectric 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 hydroelectric generator of the invention is provided with a micro-water wheel on 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 hydroelectric generator set to ensure that it faces the direction of the water flow. It has direction adjustability and increases the utilization hours of submarine hydroelectric power generation equipment. The invention not only effectively saves construction investment, but also effectively increases the utilization hours of submarine hydroelectric generators, increases the total utilization hours of the power generation system, and improves the internal rate of return of the project.

[0018] 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.
[0019] 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.
[0020] Figure 1-Figure 2 This is a specific embodiment of the present invention, which is a transition deep water jacket type wind power generation coupling direction automatically adjustable hydropower generation system, comprising a wind turbine tower and transition area 2, a jacket 3, and a jacket foundation 8. An upper layer 10 of a submarine hydroelectric generator and a lower layer 11 of a submarine hydroelectric generator are arranged at the bottom of the jacket 3, and a submarine hydroelectric generator 5 is additionally arranged between the two layers via a rotating shaft 4. This embodiment increases the power generation of the transition deep water jacket type wind power generation coupling direction automatically adjustable hydropower generation system 1, and reduces the investment amount per kilowatt.
[0021] By adding the submarine hydroelectric generator 5, the center of gravity of the transitional deepwater jacket-type wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 is effectively lowered, and the stability of the transitional deepwater jacket-type wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 is improved.
[0022] When the water flows through the submarine hydroelectric generator blades 7, it drives the submarine hydroelectric generator rotor 6 to rotate and generate electricity. The submarine hydroelectric generator micro-water wheel 9 is at the tail of the submarine hydroelectric generator rotor 6. Its main function is to be affected by the water flow and automatically change the direction of the submarine hydroelectric generator 5 to ensure that the submarine hydroelectric generator 5 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 9 can also provide partial power to increase the power of the submarine hydroelectric generator 5.
[0023] In this embodiment, a hydroelectric generator set is added at the bottom of the foundation of the conductor frame wind turbine generator set to reduce the system center and increase the system stability. The parameters of the cable and the booster station can be appropriately smaller than the sum of the parameters when the wind power generation and the hydropower generation are constructed separately, and the effective complementary utilization can reduce the unit installed capacity cost of the system. The hydroelectric generator set uses the wind generator set, and the cable parameters and the booster station parameters can be appropriately increased, which can greatly reduce the cumulative total length of the cables constructed separately, and reduce the unit installed capacity cost of the submarine hydropower station built separately. Because the large water wheel rotor of the hydroelectric generator set is also equipped with a small water wheel on one side, the small water wheel will automatically adjust the large water wheel to face the water flow after being impacted by the water flow, thereby increasing the number of hours of use of the hydroelectric generator set. By using wind turbines, it is easy to find submarine hydroelectric generator sets, and timely remind surrounding ships to reduce the probability of danger. By using wind turbine platforms, it is convenient to overhaul and operate submarine hydroelectric power generation equipment. The alarm system does not need to refer to the water level gauge, and the inaccuracy of the water level gauge does not affect the system judgment.
[0024] 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.
