Description

Technical Field

[0001] The present invention relates to the technical field of renewable energy power generation, and in particular to a wind-solar-fishing integrated device. Background Art

[0002] With the rapid advancement of the energy revolution, renewable energy power generation such as wind power generation and photovoltaic power generation has developed rapidly. Since the sea area is not only vast, but also has extremely rich wind and solar resources, the sea is extremely suitable for the development of wind power generation and photovoltaic power generation under the current development form. The existing offshore power generation device not only combines wind power generation and photovoltaic power generation, but also because the installation base of the offshore power generation device is mostly a floating buoy, combined with this floating installation base, the aquaculture function is integrated into the power generation device, and finally a wind, photovoltaic and fishery integrated device is formed that integrates wind power generation, photovoltaic power generation and fishery aquaculture.

[0003] Most of the wind-solar-fishery integrated devices use wind turbines to generate wind power. The sea breeze blows the blades of the wind turbine to rotate, and the wind turbine can convert this part of the wind energy into mechanical energy, and then drive the generator to work and generate electricity through mechanical energy. However, the blade shaft of the existing wind turbine is generally set parallel to the sea surface. Therefore, if the wind-solar-fishery integrated devices are densely arranged in the wind farm sea area, the front row of wind turbines will cause the flowing air to form turbulence behind the blades after rotation. The vortex phenomenon of turbulent motion causes the rear row of wind turbines to generate disturbances at the inflow due to the irregular distribution of kinetic energy and pressure in the vortex, resulting in unstable torque on the blades and vibration, thereby reducing the output power and power generation efficiency of the wind turbine. If the wind-solar-fishery integrated devices are arranged with larger intervals, the utilization rate of wind farm sea area resources will be reduced, and the conflict between wind, solar and fishery in the use of sea area will increase. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that if the wind-solar-fishery integrated devices are arranged densely, the output power and power generation efficiency of the wind turbine will be reduced; if the wind-solar-fishery integrated devices are arranged with larger intervals, the utilization rate of the wind farm sea area resources will be reduced, and the conflict between wind, solar and fishery in the utilization of the sea area will increase.

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figures 1 to 3 As shown, it is a preferred embodiment of the wind-solar-fishery integrated device of the present invention. This wind-solar-fishery integrated device forms an integrated development model of "offshore power generation and underwater fish farming", which can effectively improve the level of intensive utilization of various resources in the sea area.

[0042] The above-mentioned wind, light and fishery integrated device includes: a floating body 1, a wind power generation component 2, a photovoltaic power generation component 3 and a breeding component 4. The floating body 1 is arranged on the sea surface as a carrier, that is, the floating body 1 floats on the sea surface. The wind power generation component 2 can convert wind energy into electrical energy, and the wind power generation component 2 includes: a tower 21, a blade shaft 22 and a blade 23. The tower 21 is arranged on the floating body 1, and the blade shaft 22 is arranged on the tower 21, and the blade shaft 22 is arranged perpendicular to the sea surface, that is, the blade shaft 22 is arranged in the vertical direction. A plurality of blades 23 are arranged along the circumference of the blade shaft 22 and connected to the blade shaft 22. The blades 23 are symmetrical airfoil blades 23 with high wind energy utilization. The photovoltaic power generation component 3 can absorb solar energy to generate electricity, and the photovoltaic power generation component 3 is also arranged on the floating body 1. The breeding component 4 is arranged at the bottom of the floating body 1, that is, the breeding component 4 is located below the sea surface, and uses the marine environment to breed fish and other marine organisms. Since the blade shaft 22 in this wind power generation component 2 is arranged perpendicular to the sea surface, the turbulence generated by the blade 23 when rotating will also be in the vertical direction, so as not to affect other surrounding wind power generation components 2. Moreover, the airflow generated when the blade 23 of each wind turbine rotates can increase the pressure difference between the inner and outer surfaces of the blade 23 of the adjacent wind turbine. The larger pressure difference increases the rotation speed of the blade 23, so that the wind energy utilization coefficient will be improved. The rotation direction of the blades 23 in adjacent wind turbines can be the same or opposite, and when the rotation directions of the blades 23 of adjacent wind turbines are opposite, the wind energy utilization coefficient is higher than the wind energy utilization coefficient of the arrangement mode of rotating in the same direction. Because when the blades 23 of adjacent wind turbines rotate in opposite directions, a canyon effect will be formed between the wind turbines, so that wind acceleration will be generated in the gap between them, thereby increasing the downstream incoming wind speed, which increases the incident free stream speed of the downstream wind turbine at certain positions. When the spacing between wind turbines is small, the wind acceleration effect of the gap is better. Therefore, this type of wind, solar and fishery integrated device is suitable for close arrangement in the wind farm sea area, which can make full use of the wind energy resources in the wind farm sea area, improve the efficiency of wind power generation, effectively improve the level of conservation and intensive utilization of marine resources, and reduce the cost per kilowatt-hour.

[0043] The wind power generation assembly 2 also includes a plurality of connecting members 24, which are arranged along the radial direction of the blade shaft 22. Each blade 23 is connected to the blade shaft 22 via a connecting member 24. The wind power generation assembly 2 of this structure has a lower load on the upper part and a higher overall stability of the device. Specifically, in this embodiment, a total of three blades 23 are provided, and the angle between two adjacent blades 23 is 60°, and the number of corresponding connecting members 24 is also three.

[0044] Furthermore, the wind power generation assembly 2 also includes: a transmission mechanism and a power generation device, the blade shaft 22 is connected to the power input end of the transmission mechanism, and the power output end of the transmission mechanism is connected to the power generation device. When the wind at sea drives the blades 23 to rotate, it will synchronously drive the blade shaft 22 to rotate, realizing the conversion of wind energy to mechanical energy. The blade shaft 22 is connected to the transmission mechanism and outputs the rotation speed to the power generation device after increasing the rotation speed. The power generation device works to generate electricity, realizing the conversion of mechanical energy to electrical energy.

[0045] Furthermore, a reflective layer is provided on the surface of the blade 23 and the tower 21. The reflective layer can be a metal sheet attached to the surface of the blade 23 and the tower 21 or a reflective coating applied to the surface of the blade 23 and the tower 21. By providing the reflective layer, the sunlight irradiated on the blade 23 and the tower 21 can be reflected to the photovoltaic power generation assembly 3, so as to enhance the radiation intensity of the photovoltaic power generation assembly 3 and improve the efficiency of photovoltaic power generation.

[0046] In other embodiments, the blades 23 and the tower 21 may also be made of a material with high reflectivity, such as glass, which can also reflect the sunlight irradiated on the blades 23 and the tower 21 to the photovoltaic power generation assembly 3.

[0047] Furthermore, the float 1 is made of HDPE (high-density polyethylene) material, has great buoyancy, can stably float on the sea surface, and has strong corrosion resistance and a long service life. It can provide sufficient bearing capacity for the wind power generation component 2, the photovoltaic power generation component 3 and the breeding component 4. Specifically, the float 1 is hollow inside and has a truncated cone shape, and the size of the float 1 decreases uniformly from its top surface to the bottom surface, that is, the float 1 is small at the top and large at the bottom. The edge of the float 1 of this shape is streamlined, which can weaken the impact of waves on the device, and the stability of the device is better. Moreover, the inclined side of the float 1 can prevent seawater from pouring into the float 1 and damaging the photovoltaic power generation component 3 when encountering the impact of waves.

[0048] In other embodiments, the floating body 1 may also be cylindrical.

[0049] The photovoltaic power generation assembly 3 can generate electricity using solar energy, and includes a plurality of photovoltaic panels 31, which are arranged on the floating body 1 around the tower 21, that is, the photovoltaic panels 31 are arranged in the hollow cavity of the floating body 1. The photovoltaic panels 31 are directly irradiated by sunlight, reflected by the sea surface, etc., and convert solar energy into electrical energy to achieve photovoltaic power generation. In addition, the back of the photovoltaic panel 31 can be cooled by seawater, thereby improving the heat dissipation performance of the photovoltaic panel 31.

[0050] Furthermore, the breeding component 4 includes: a breeding box 41. The breeding box 41 is a cylindrical box, in which fish and other organisms are cultured. The top surface of the breeding box 41 is connected to the bottom surface of the floating body 1, but the outer edge size of the breeding box 41 is larger than the outer edge size of the floating body 1. The floating body 1 is opaque, so the bottom of the floating body 1 is shielded from sunlight for a long time, which is very suitable for the growth of algae, and the algae can be used as feed for the organisms in the breeding box 41. The breeding box 41 is light-transmitting, providing sufficient light for the organisms in the breeding box 41. In addition, the outer wall of the breeding box 41 has a plurality of mesh holes, through which the circulation of seawater is realized, so that substances in the ocean can be exchanged with the inside of the breeding box 41, meeting the needs of the organisms in the breeding box 41 and promoting their growth.

[0051] In other embodiments, the breeding box 41 may also be a hemispherical box.

[0052] In addition, a plurality of floating balls 5 are arranged on the outer wall of the breeding box 41, which can further improve the buoyancy of the device and increase the stability of the device.

[0053] The working process of the wind-light-fishing integrated device provided in this embodiment is described as follows:

[0054] A plurality of wind, light and fishery integrated devices are densely arranged in the sea area of ​​the wind farm. The blades 23 of the wind power generation component 2 are rotated by the sea breeze. The rotation of the blades 23 drives the blade shaft 22 to rotate, and then the transmission mechanism drives the generator to work and generate electricity, thus realizing wind power generation. In the process of using wind energy to generate electricity, due to the change in the setting direction of the blade shaft 22, the turbulence generated by the rotation of the blades 23 will not have an adverse effect on the surrounding wind power generation components 2. Instead, the mutual interference greatly increases the energy density of the wind farm and improves the output efficiency of each wind power generation component 2. Not only the utilization rate of wind energy in the wind farm sea area is improved, but also the efficiency of wind power generation is improved.

[0055] The photovoltaic power generation assembly 3 receives direct sunlight, reflection from the sea surface, and reflection from blades 23 and tower 21 through a plurality of photovoltaic panels 31 , and converts solar energy into electrical energy.

[0056] Marine organisms are cultured in the culture box 41 disposed at the bottom of the floating body 1 , and grow through algae growing on the bottom of the floating body 1 and absorbing nutrients from the ocean.

[0057] The floating body 1 maintains the stability of the entire device, so that the center of gravity of the entire device is at sea level, and it can remain stable in strong winds and large waves. This device can enable the coordinated development of "wind, light and fishery", is conducive to the virtuous cycle of the marine ecological environment, and optimizes the use of marine space. "Wind, light and fishery" can achieve efficient use of resources by sharing marine space. This sharing and optimized layout of space can reduce disturbance to the marine ecological environment, reduce land use conflicts, and improve the sustainable development of energy and marine products.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
