Description

Technical Field

[0001] The utility model relates to the technical field of power generation equipment, in particular to a jacket-type wind power generation coupling direction automatically adjustable hydropower generation system. Background Art

[0002] Existing jacket-mounted wind turbines are limited to a single type of power generation equipment: wind turbines, which utilize wind energy to generate electricity, and submarine hydroelectric generators, which utilize tidal and ocean current energy to generate hydroelectric power. Under current technical conditions, separate investments in wind and submarine hydroelectric power generation face high investment costs per unit of installed capacity. Current power generation equipment of this type suffers from the following issues:

[0003] (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.

[0004] (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.

[0005] (3) Submarine hydropower generation currently has a small power generation capacity and requires separate construction. The amount of cables required for supporting construction is large and it does not have a competitive advantage.

[0006] (4) Submarine hydropower equipment cannot automatically adjust its direction according to the direction of water flow, and its utilization hours are relatively low.

[0007] (5) Submarine hydropower generation equipment is more difficult to detect than offshore wind power and has a greater impact on the surrounding ships and other dangerous items.

[0008] (6) Submarine hydropower equipment is difficult to inspect, repair, and maintain.

[0009] 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

[0010] In order to make up for the deficiencies in the prior art, the utility model provides a jacket-type wind power generation coupling direction automatically adjustable hydropower generation system.

[0011] A jacket-type wind power generation coupling direction automatically adjustable hydropower generation system includes a jacket foundation and is characterized by:

[0012] 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.

[0013] 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 jacket, and the lower layer of the submarine hydroelectric generator is connected to the upper part of the jacket foundation.

[0014] Furthermore, in order to better realize 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.

[0015] Furthermore, in order to better realize 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.

[0016] 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.

[0017] The beneficial effects of the utility model are:

[0018] The utility model couples wind power generation and hydropower generation, and can effectively utilize existing investments in existing wind turbines such as the jacket foundation, cables, booster stations, and transmission lines. When the technical parameters are appropriately adjusted, hydropower generation equipment can be added. This technology reduces unit construction costs, 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 lowered, 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 directional 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.

[0023] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0024] 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 claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0025] Figure 1-Figure 2 This is a specific embodiment of the present invention, a jacket-mounted wind turbine generation system with automatically adjustable coupling direction for transitional deepwater applications. The system comprises a wind turbine tower and transition region 2, a jacket 3, and a jacket foundation 8. An upper subsea hydroelectric generator layer 10 and a lower subsea hydroelectric generator layer 11 are located at the bottom of the jacket 3, with a subsea hydroelectric generator 5 located between the two layers via a rotating shaft 4. This embodiment increases the power generation capacity of the jacket-mounted wind turbine generation system with automatically adjustable coupling direction for transitional deepwater applications 1, while reducing the investment per kilowatt.

[0026] By adding the submarine hydroelectric generator 5, the center of gravity of the jacket-type wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 in transitional deep water area is effectively lowered, and the stability of the jacket-type wind power generation coupling direction automatically adjustable hydroelectric power generation system 1 in transitional deep water area is improved.

[0027] When 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-turbine 9, located at the tail of the submarine hydroelectric generator rotor 6, is primarily influenced by the water flow and automatically changes the direction of the submarine hydroelectric generator 5, ensuring that the submarine hydroelectric generator 5 faces the water flow. This directional adjustability increases the utilization hours of the submarine hydroelectric power generation equipment. The submarine hydroelectric generator micro-turbine 9 also provides partial power, increasing the output of the submarine hydroelectric generator 5.

[0028] This embodiment adds a hydroelectric generator set to the base of the jacket-type wind turbine foundation, lowering the system center and increasing system stability. The cable and booster station parameters can be appropriately smaller than the sum of the parameters of the wind and hydroelectric generators when constructed separately, effectively complementing each other and reducing the system's unit installed capacity cost. The hydroelectric generator set utilizes the wind turbine set by appropriately increasing the cable and booster station parameters. This significantly reduces the cumulative length of cables constructed separately and reduces the unit installed capacity cost of a separate submarine hydroelectric power station. Because the hydroelectric generator set's large turbine rotor is accompanied by a small turbine, the small turbine automatically adjusts to face the current when impacted by the current, increasing the hydroelectric generator set's operating hours. The wind turbine makes it easier to spot the submarine hydroelectric generator set, providing timely alerts to surrounding vessels and minimizing the risk of danger. The wind turbine platform facilitates the inspection, maintenance, and operation of submarine hydroelectric equipment. This alarm system does not require a water level gauge, and inaccurate water level gauges do not affect the system's response.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
