As one of the most extensive resource treasures on the earth, the ocean contains abundant energy, such as wave energy, tidal energy, wind energy and solar energy. Under the existing technical conditions, over-reliance on a single development method often fails to fully tap the huge potential of marine energy, which in turn largely limits its greater role in the energy field. Summary of the invention

[0003] The purpose of the present invention is to provide a wind-light-wave integrated power generation platform that can adapt to multiple wind and wave directions, and can realize multi-energy co-generation of wind energy, solar energy and wave energy in the same space.

On the one hand, it reduces dependence on a single energy source and improves the stability of energy supply; on the other hand, it greatly improves the comprehensive utilization rate of energy and realizes the complementary advantages of multiple energy sources. This integrated power generation platform provides a new direction and ideas for future energy development.

[0004] To achieve the above-mentioned purpose, the present invention provides a wind-light-wave integrated power generation platform that can adapt to multiple wind and wave directions, including a floating platform, a plurality of wind turbines are arranged on the edge of the top of the floating platform, a photovoltaic panel is arranged at the center of the top of the floating platform through a photovoltaic bracket, a wave energy device is arranged inside the floating platform, and the wind turbine is specifically configured as a vertical axial wind turbine.

[0005] Preferably, the wave energy device includes an outer shell, a sliding rod is arranged inside the outer shell, and the sliding rod is arranged as an upper limiter, an upper counterweight, a PTO device, a lower counterweight and a lower limiter from top to bottom, and the upper limiter is connected to the inner side of the top of the outer shell through a spring.

[0010] Therefore, the present invention adopts the above-mentioned wind-light-wave integrated power generation platform that can adapt to multiple wind and wave directions, which has the following advantages:

[0011] (1) In the present invention, the wave energy device is isolated from the complex marine environment, which is conducive to improving the stability and service life of the wave energy device.

The vertical axis wind turbine has relatively good stability under strong wind conditions and can withstand large wind forces. The wave energy device can absorb wave energy and reduce the load on the platform. The combination of the vertical axis wind turbine, the wave energy device and the floating platform can better resist the impact of strong winds and waves in extreme weather.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. The specific model specifications need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0021] Example

[0022] like Figure 1-Figure 4 As shown, the present invention provides a wind-light-wave integrated power generation platform adaptable to multiple wind and wave directions, including a floating platform 3, a plurality of wind turbines are arranged on the edge of the top of the floating platform 3, a photovoltaic panel 22 is arranged at the center of the top of the floating platform 3 through a photovoltaic bracket 21, and a wave energy device 4 is arranged inside the floating platform 3. The wave energy device 4 is built in the floating platform, so that the wave energy device 4 can work under the condition of isolation from the complex marine natural environment.

[0023] The wave energy device 4 includes an outer shell 41, and a sliding rod 43 is arranged inside the outer shell 41. The sliding rod 43 is arranged from top to bottom as an upper limiter 44, an upper counterweight block 42, a PTO device, a lower counterweight block 48 and a lower limiter 49. The upper limiter 44 is connected to the inner side of the top of the outer shell 41 through a spring 45. The PTO device includes a permanent magnet synchronous linear motor and a brake controller. The stator 46 of the permanent magnet synchronous linear motor is fixed on the inner side of the outer shell 41, and the mover 47 of the permanent magnet synchronous linear motor is fixed on the sliding rod 43. The upper limiter 44 and the lower limiter 49 can effectively control the moving range of the internal structure of the wave energy device 4 to avoid damage to the equipment due to over-limit.

[0024] The fan is specifically configured as a vertical axis fan 1. Each vertical axis fan includes a base 13. A fixed axis 12 is vertically arranged on the base 13. Three airfoil blades 11 are arranged on the side of the top of the fixed axis 12. The airfoil blades 11 are horizontally rotated and the blades are designed in the shape of an airplane wing. The horizontal rotation can reduce noise pollution and resist stronger winds. When the airfoil blades 11 are rotated by wind, they only bear the pressure of the fan and the tension of the rotating centrifugal force on the fan, which reduces the requirements for the strength of the blade material.

[0025] Among them, the floating platform, counterweight and shell form a multi-resonance system, and the motion equation of the multi-resonance system is:

[0026]

[0027] in x 外 They represent the acceleration of the floating platform, the movement speed of the floating platform, and the displacement distance of the floating platform respectively. represents the acceleration of the counterweight of the internal wave energy device, M is the total mass of the floating platform, m is the mass of the counterweight of the internal wave energy device, μ 附加 is the additional mass of the floating platform, B 辐射 and B 粘性 are the radiation damping and viscous damping of the floating platform, respectively, and C 恢复 represents the restoring force coefficient of the floating platform, F 波激 and F 风 represents the wave excitation force and wind force on the platform, F PTO Indicates the PTO force between the platform and the counterweight.

[0028] The specific use process is as follows: a total of eight vertical axis wind turbines are installed on the floating platform. The vertical axis wind turbine is equipped with three blades. The blade shape adopts the airfoil design principle, and the base and fixed shaft play a fixing role. The vertical axis wind turbine adopts horizontal rotation to reduce noise pollution and resist stronger winds. When the airfoil blades are rotated by wind, they only bear the pressure of the wind turbine and the tension generated by the rotating centrifugal force on the wind turbine, which reduces the requirements for the strength of the blade material.

[0029] The shell of the wave energy device is fixed inside the floating platform, and a PTO device is arranged inside the shell. The stator of the permanent magnet linear motor in the PTO device is fixed inside the shell, and the stator and the counterweight of the permanent magnet linear motor are rigidly fixed on the sliding rod. The top and bottom of the shell are respectively provided with limiters to limit the displacement of the counterweight and reduce the impact of the movement of the counterweight on the top of the shell. The wave energy device 4 is built into the floating platform so that the wave energy device can work under the condition of being isolated from the complex marine natural environment.

[0030] The limiter in the wave energy device can prevent the displacement of the counterweight block from being too large and causing damage to the platform. When the counterweight block moves close to the top or bottom of the device, the limiter comes into play and limits the displacement of the mass block by generating resistance, so that it cannot continue to move at high speed and hit the platform, thereby protecting the integrity and stability of the platform structure.

[0031] Therefore, the present invention adopts a wind-light-wave integrated power generation platform that can adapt to multiple wind and wave directions, and can realize the multi-energy co-generation of wind energy, solar energy and wave energy in the same space. In the vast ocean, the distribution of wind energy, wave energy and solar energy is highly overlapped. Through this integrated system, this feature can be fully utilized. On the one hand, it reduces the dependence on a single energy source and improves the stability of energy supply; on the other hand, it greatly improves the comprehensive utilization rate of energy and realizes the complementary advantages of multiple energy sources. This integrated power generation platform provides a new direction and ideas for future energy development.

[0032] 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. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
