Description

Technical Field

[0001] This utility model relates to the field of power generation technology, specifically a novel integrated offshore wind, solar and wave power generation device. Background Technology

[0002] In recent years, global energy consumption has continued to grow, leading to severe environmental pollution and climate change. The ocean, covering approximately 71% of the Earth's surface, possesses abundant renewable energy potential, such as wind, solar, and wave energy, which can provide sustainable solutions to global energy needs. Therefore, how to more effectively utilize various clean marine energy sources has become an urgent issue. Furthermore, my country's development into a maritime power is inseparable from energy-intensive activities such as far-sea scientific research and military exercises. Constructing energy islands and transporting diesel fuel is too costly and not a long-term solution.

[0003] The wake effect refers to the weakening and turbulence that occurs when wind passes over a wind turbine, affecting the power generation of turbines located at the wake. Therefore, most modern wind power structures employ vertical configurations. When natural wind acts on these structures, most of the incoming airflow enters the central open area without effective guidance. This airflow is obstructed upon contact with the turbine blades and internal support components, causing turbulent flow and creating numerous irregular vortices within the open space. These vortices significantly increase airflow resistance, reducing the effective wind energy captured by the turbine blades, and also exert unstable impact loads on the turbine blades and the entire structure. This directly reduces the overall power generation efficiency of the wind power system, and long-term unstable impacts exacerbate fatigue wear on critical components such as blades and bearings, shortening equipment lifespan and ultimately hindering the development of vertical axis wind power technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel integrated offshore wind, solar, and wave power generation device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A novel integrated offshore wind, solar, and wave power generation device, comprising

[0007] The main body of the power generation device consists of, from bottom to top, a support base, a solar panel, a wind power generation component, and duck-shaped structures on both sides of the solar panel;

[0008] Wind power generation components, including:

[0009] A drive shaft is connected to the top surface of the solar panel;

[0010] A connecting bracket is attached to the outer surface of the drive shaft, and the connecting bracket has a V-shaped structure with the opening of the V-shaped structure facing away from the drive shaft;

[0011] The windward plate is connected to one side of the opening of the V-shaped structure of the connecting frame, and the windward plate is distributed in a ring shape around the drive shaft. The top cross-sectional shape of the windward plate is arc-shaped.

[0012] The concave surface of the wind-facing plate is the wind-facing surface. When external wind comes into contact with the wind-facing plate, the concave surface guides the wind to both sides of the wind-facing plate.

[0013] Preferably, when a single wind-facing plate is facing the wind, the two ends of the single wind-facing plate and the ends of the adjacent wind-facing plates that are close to the single wind-facing plate are on the same vertical line.

[0014] Preferably, the windward surface of the windward side is provided with a plurality of inclined plates, and the inclined end of the inclined plate faces the opposite direction to the wind blowing direction.

[0015] Preferably, the outer convex surface of the windward plate is provided with a plurality of fixed plates perpendicular to the outer convex surface. When the windward plate rotates, the fixed plates form a stable vortex between the multiple inner convex surfaces of the windward plate.

[0016] Preferably, the connection points between the windward plate and the connecting frame are symmetrically distributed with the center of the windward plate in the vertical direction as the center.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By using the concave surface of the windward side to guide the wind, the wind is directed to both sides of the windward plate. The concave surfaces of adjacent windward plates then guide the sea breeze away from the windward plate. This prevents the sea breeze from entering the hollow area of ​​the windward plate, which would cause airflow turbulence, leading to the loss of a large amount of sea breeze and affecting wind power generation. At the same time, the stable airflow ensures that the windward plate, connecting frame, and drive shaft are always under uniform stress, reducing additional mechanical stress, lowering the probability of failure, and extending the overall service life of the wind power generation components.

[0026] Example

[0027] like Figure 1-4 As shown, a novel integrated offshore wind, solar, and wave power generation device includes...

[0028] The main body of the power generation device 1 consists of, from bottom to top, a support base 11, a solar panel 12, a wind power generation component 13, and a duck-shaped body 14 disposed on both sides of the solar panel 12;

[0029] Wind power generation component 13, including:

[0030] A drive shaft 131 is connected to the top surface of the solar panel 12;

[0031] The connecting bracket 132 is connected to the outer surface of the drive shaft 131, and the connecting bracket 132 has a V-shaped structure, with the opening of the V-shaped structure facing away from the drive shaft 131.

[0032] The windward plate 133 is connected to one side of the V-shaped structure opening of the connecting frame 132, and the windward plate 133 is distributed in a ring shape around the drive shaft 131. The top cross-sectional shape of the windward plate 133 is arc-shaped.

[0033] Among them, the concave surface of the wind-facing plate 133 is the wind-facing surface. When the external wind comes into contact with the wind-facing plate 133, the concave surface guides the wind to both sides of the wind-facing plate 133.

[0034] Specifically: The device can be directly installed at sea via the support base 11 at the bottom. Once installed, the solar panel 12 is located in the upper part of the device, unobstructed and with a better angle of light reception, which can efficiently capture solar radiation energy and directly convert light energy into electrical energy through photovoltaic conversion components. The wind power generation component 13 is distributed above the solar panel 12 around the drive shaft 131. Located in the high wind speed area at sea, it can fully contact the sea breeze and convert wind energy into electrical energy through mechanical transmission. The duck body 14 is symmetrically arranged on both sides of the solar panel 12. Its position and height are adapted to the wave activity range, and it can directly contact the reciprocating waves. The swing or vibration of the duck body 14 drives the internal transmission mechanism to convert the kinetic and potential energy of the waves into electrical energy. The three form an integrated power generation system that complements multiple energy sources of "solar, wind, and waves", avoiding power outages caused by fluctuations in a single energy source and improving the overall stability of power output.

[0035] To further explain, during the process of wind power generation component 13 converting wind energy, firstly, the sea breeze acts on the concave windward surface of the windward plate 133. Since the windward plate 133 is distributed in a ring shape around the drive shaft 131 and is fixed to the drive shaft 131 through the V-shaped connecting frame 132, the thrust generated by the sea breeze on the windward plate 133 is first transmitted to the V-shaped connecting frame 132. Subsequently, the concentrated force is transmitted to the drive shaft 131 through the V-shaped connecting frame 132, causing the drive shaft 131 to make uniform circular motion around its own axis. Finally, the drive shaft 131 transmits the mechanical rotational kinetic energy to the electrical energy conversion module at the bottom, such as a generator.

[0036] To further explain, when the sea breeze blows towards the windward plate 133, the concave surface of the arc can change the direction of airflow. The airflow will not directly impact the plate and scatter, but will flow smoothly along the arc of the concave surface to both sides of the windward plate 133. This is the "first step" of airflow guidance. At the same time, because the windward plates 133 are distributed in a ring shape around the drive shaft 131, the airflow on both sides of a single windward plate 133 will directly contact the concave surface of the adjacent windward plate 133. The concave surface of the adjacent windward plate 133 is also arc-shaped, which can form a "secondary guidance" for this part of the airflow. This further pushes the airflow away from the center of the drive shaft 131, ultimately causing the airflow to completely leave the hollow area between the windward plates 133. This prevents sea breeze from entering the hollow area of ​​the windward plates 133, thus avoiding airflow turbulence, which would lead to the consumption of a large amount of sea breeze and affect wind power generation. At the same time, the stable airflow ensures that the windward plates 133, connecting frame 132, and drive shaft 131 are always under uniform stress, reducing additional mechanical stress, lowering the probability of failure, and extending the overall service life of the wind power generation components 13.

[0037] In this embodiment: when a single wind-facing plate 133 is facing the wind, the two ends of the single wind-facing plate 133 and the ends of the adjacent wind-facing plates 133 that are close to the single wind-facing plate 133 are on the same vertical line.

[0038] Specifically: In the previous design, the core function of the concave surface of the windward plate 133 was to guide the sea breeze to both sides of the plate, preventing airflow from entering the hollow area. The vertical line of the end further blocked the misalignment gap between adjacent plates. If the end is not aligned, such as one side protruding and the other side retracting, triangular or irregular gaps will be formed between adjacent plates. The sea breeze guided to both sides of a single plate may still enter the hollow area through the gap, causing local turbulence. When the end is on the same vertical line, the gap between adjacent plates is a regular vertical narrow gap rather than a misaligned gap. After the sea breeze is guided to both sides of a single plate, it will be discharged directly outward along the vertical narrow gap and cannot enter the hollow area. This completely solves the problem of secondary turbulence after airflow guidance and makes the wind guiding function of the concave surface fully realized.

[0039] In this embodiment, multiple inclined plates are provided on the windward side of the windward side, and the inclined end of the inclined plate faces the opposite direction to the wind blowing direction.

[0040] Specifically: When the sea breeze blows towards the windward plate 133 along the concave surface, without the inclined plate, some of the sea breeze may slide directly over due to the curvature of the concave surface, generating only a small thrust; while the inclined plate with the opposite inclination will form a reverse obstruction. After the sea breeze comes into contact with the inclined plate, it cannot slide away directly and must go around along the inclined surface of the plate upward or to the sides. During this process, the inclined plate will be continuously subjected to the squeezing thrust of the sea breeze, and multiple inclined plates can gather the dispersed kinetic energy of the sea breeze into a concentrated thrust, which directly acts on the main body of the windward plate 133, and the torque that drives the windward plate 133 to rotate around the drive shaft 131 is greater, thereby improving the wind energy conversion efficiency of a single plate from the source.

[0041] In this embodiment, the outer convex surface of the windward plate 133 is provided with a plurality of fixed plates perpendicular to the outer convex surface. When the windward plate 133 rotates, the fixed plates form a stable vortex between the inner convex surfaces of the plurality of windward plates 133.

[0042] Specifically: When the sea breeze first acts on the main force-generating surface of the concave side of the windward plate 133, some wind energy will be converted into the power to drive the windward plate 133 to rotate. However, there will still be residual airflow flowing between the concave sides of multiple windward plates 133. If this part of the wind energy is not utilized, it will be directly lost. When the windward plate 133 rotates, the vertical fixed plate on the convex side will act like a guide vane to apply a rotational guiding force to this part of the residual airflow, so that it forms a clockwise or counterclockwise stable vortex between the concave sides of adjacent windward plates 133. The rotational kinetic energy of this vortex will continuously generate additional thrust on the concave sides of the windward plates 133 on both sides. When the vortex rotates upward, it will form a downward thrust on the concave side of the upper windward plate 133 and an upward thrust on the concave side of the lower windward plate 133. This is equivalent to converting the residual wind energy after the first use into a secondary driving force, which directly assists the rotation of the windward plate 133, significantly improving the overall utilization rate of wind energy of the entire wind power generation unit 13.

[0043] To further explain, the stable vortex formed by the fixed plate is equivalent to establishing a unified airflow circulation path for the gap area: all residual airflow will be assimilated by the vortex and circulate in an orderly manner in a fixed direction, and there will be no more turbulent flow with conflicting directions; at the same time, the stable vortex can also block external interfering airflow, prevent it from disrupting the airflow balance between the concave surfaces, further consolidate the airflow stability of the entire windward plate 133, and ensure that the main wind force conversion process is not disturbed.

[0044] In this embodiment, the connection points between the windward plate 133 and the connecting frame 132 are symmetrically distributed with the center of the windward plate 133 in the vertical direction as the center.

[0045] Specifically: When the windward plate 133 receives the thrust of the sea wind, all the wind force will be transmitted to the connecting frame 132 through the connection point, and then drive the drive shaft 131 to rotate. If the connection point is not symmetrical, the wind force will form an eccentric moment on the plate. For example, when the connection point is too high, the lower part of the windward plate 133 will be subjected to downward bending stress due to the inability to effectively transmit the force. Over time, this can easily lead to plate deformation or connection point breakage. Symmetrically distributed connection points can allow the force on the vertical up and down or left and right areas of the windward plate 133 to be evenly transmitted to the connecting frame 132 through the symmetrical points. The stress in each part of the plate is consistent in magnitude and balanced in direction, which completely eliminates the eccentric moment, avoids local stress concentration, and significantly improves the structural damage resistance of the windward plate 133 under strong winds and long-term rotation, making it suitable for high-load operating environments at sea.

[0046] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
