Technical Field

[0001] This invention relates to the field of renewable energy utilization technology, and in particular to a wind and solar power generation device with self-protection function. Background Technology

[0002] Wind energy is the fastest-growing clean energy source among renewable energy sources, and wind power generation is also the power generation method with the greatest potential for large-scale development and commercialization.

[0003] Among related technologies, wind power generation is significantly affected by wind conditions. During the windy season, wind turbines can generate sufficient electricity to feed into the grid. However, during the weaker windy season, the output of wind turbines is significantly insufficient, making it difficult to meet demand. This results in wind power generation being unable to provide users with a continuous and stable supply of electricity throughout different seasons, limiting the promotion and application of wind power technology. Furthermore, in severe weather conditions such as typhoons and storms, the blades of wind turbines are easily and severely damaged, causing the turbines to malfunction and fail to generate electricity. Summary of the Invention

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The wind and solar power generation device with self-protection function according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, the wind and solar power generation device of this embodiment includes a base 1, a cylinder 2, a nacelle 3, a power generation component (not shown), and multiple wind turbine blades 4. The base 1 is used to support the cylinder 2. A part of the base 1 is buried underground, or the entire base 1 is buried underground, to ensure the structural stability of the wind and solar power generation device.

[0027] The cylinder 2 is the main part of the entire wind and solar power generation device. It is mainly used to provide sufficient height for installing the power generation components and wind turbine blades 4. The height of the cylinder 2 can generally range from tens of meters to hundreds of meters.

[0028] The nacelle 3 is located at the upper end of the cylinder 2, the power generation components are located inside the nacelle 3, and thin-film solar panels are provided on the outer surface of the wind turbine blades 4 and / or the outer circumferential surface of the cylinder 2. Both the wind turbine blades 4 and the solar panels are connected to the power generation components.

[0029] It is understood that the wind and solar power generation device with self-protection function in this embodiment of the invention has two power generation systems: wind power generation and solar power generation. Wind power generation converts wind energy into kinetic energy through the wind turbine blades 4, and then converts the kinetic energy into electrical energy. Solar power generation converts solar energy into electrical energy through thin-film solar panels installed on the outer surface of the wind turbine blades 4 and / or the outer circumference of the cylinder 2. The two power generation systems can work independently or simultaneously. For example, in seasons with strong winds and sufficient sunshine, wind and solar power generation can be used simultaneously. In seasons with weak winds but sufficient sunshine, compared with traditional wind power generation or solar power generation, the wind and solar power generation device in this embodiment of the invention has higher power generation efficiency, better stability, and a wider range of applications.

[0030] In some embodiments, the wind turbine blades 4 are switchable between an open position and a closed position. In the open position, the wind turbine blades 4 can be used for wind power generation and / or solar power generation. In the closed position, multiple wind turbine blades 4 are stacked.

[0031] The open position of fan blade 4 is the normal operating position, such as... Figure 1 As shown, the three blades are arranged circumferentially along the input shaft 6 of the motor. The closed position of the wind turbine blade 4 is the protective position, which can reduce the wind-facing area of ​​the wind turbine blade 4. With this setting, when there is a storm or other severe weather, the wind turbine blade 4 will switch to the closed position to reduce the windward area, which can effectively prevent the wind turbine blade from being easily damaged and ensure the normal operation of the wind and solar power generation device.

[0032] The wind and solar power generation device of this invention can generate electricity using both wind and solar energy simultaneously. It can be adjusted according to different wind directions and sun positions, has a wide range of applications, good stability, and higher power generation efficiency. In addition, it can also protect itself by closing the wind turbine blades in the event of severe weather, thus improving the reliability of the device.

[0033] Specifically, the power generation assembly includes a first power generation assembly for wind power generation and a second power generation assembly for solar power generation. The first power generation assembly is connected to the wind turbine blades 4, and the second power generation assembly is connected to the solar panel. The first power generation assembly is used for wind power generation, and the second power generation assembly is used for solar power generation. It should be noted that both wind power generation and solar power generation are mature existing technologies; therefore, their specific components will not be described in detail, but only the technical features that contribute to solving the technical problems will be described.

[0034] With this setup, the two power generation components can work independently without affecting each other. For example, if the wind turbine blade 4 experiences a mechanical failure that prevents the first power generation component from generating electricity, the second power generation component can still generate electricity normally.

[0035] like Figures 1-3 As shown, in some embodiments, the first power generation component includes a generator and a universal rotating head 5 connected to the input shaft 6 of the generator. The wind turbine blades 4 are connected to the universal rotating head 5. On the one hand, the wind turbine blades 4 can drive the input shaft 6 of the generator to rotate to generate electricity. On the other hand, the universal rotating head 5 can drive the wind turbine blades 4 to rotate to adjust the pitch angle and sway angle of the wind turbine blades 4.

[0036] Therefore, the orientation of the wind turbine blades 4 can be adjusted by rotating the nacelle 3 and rotating the rotating head, so that they can face the wind direction at the most appropriate angle. The traditional blade arrangement is that the rotating surface of the blade is perpendicular to the horizontal plane. The wind turbine blades 4 of the wind and solar power generation device in this embodiment of the invention break through the traditional blade arrangement, which is more flexible and can adjust the angle of the wind turbine blades 4 arbitrarily, always ensuring that the wind turbine is at a 90-degree angle to the wind direction.

[0037] In addition, such as Figures 4-6 As shown, when the wind turbine blades 4 are in the closed position, the universal rotating head 5 can also drive the stacked wind turbine blades 4 to rotate, making them parallel to the wind direction. This can minimize the damage to the wind turbine blades 4 caused by excessive wind speed, ensure the normal operation of the wind and solar power generation device, and improve the reliability of the device.

[0038] Furthermore, one end of the fan blade 4 is rotatably connected to the universal rotating head 5. The fan blade 4 can rotate around the circumference of the universal rotating head 5 to switch between the open position and the closed position. In other words, the universal rotating head 5 can drive the fan blade 5 to rotate in any direction, and the fan blade 5 can rotate around the circumference of the universal rotating head 5. Thus, the universal rotating head 5 can drive the fan blade 4, which is in the open or closed position, to rotate to adjust its position, so that the fan blade 4 faces the wind or extends along the wind direction.

[0039] Specifically, in the closed position, the stacked fan blades 4 extend vertically or along the wind direction. When the fan blades 4 are set vertically, the windward area is changed from the total area of ​​multiple fan blades 4 to the area of ​​a single fan blade 4, which can reduce the possibility of damage to the fan blades 4 to a certain extent. When the fan blades 4 are arranged along the wind direction, the wind cannot directly blow the fan blades 4, thereby avoiding damage to the fan blades 4 to the greatest extent.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the wind turbine blade 4 includes a first blade segment 41 and a second blade segment 42. One end of the first blade segment 41 is rotatably connected to the universal rotating head 5, and one end of the second blade segment 42 is rotatably connected to the other end of the first blade segment 41.

[0041] The first leaf segment 41 can rotate circumferentially along the universal rotating head 5 to drive the second leaf segment 42 to switch between the open and closed positions. The second leaf segment 42 can rotate around the central axis of the first leaf segment 41 to adjust the angle between the first leaf segment 41 and the second leaf segment 42.

[0042] It should be noted that when the wind and solar power generation device generates wind power, the second blade segments 42 of multiple wind turbine blades 4 cannot be parallel to each other, otherwise the wind turbine blades 4 cannot rotate normally and the first power generation component cannot generate electricity. However, when the wind and solar power generation device only generates solar power, the second blade segments 42 of multiple wind turbine blades 4 can be parallel to each other to increase the light-receiving area of ​​the wind turbine blades 4.

[0043] Specifically, the open positions of the wind turbine blade 4 include a first open position and a second open position. The first blade segment 41 has a first windward surface 411, and the second blade segment 42 has a second windward surface 421. In the first open position, the extended surfaces of the first windward surface 411 intersect, and the wind and solar power generation device can be used for both wind power generation and solar power generation at the same time. In the second open position, the first windward surface 411 and the second windward surface 421 coincide, and the wind and solar power generation device can only be used for solar power generation at this time.

[0044] In some embodiments, the wind and solar power generation device further includes a controller (not shown), which is used to adjust the power generation mode of the wind and solar power generation device and the movement of the wind turbine blades 4. It should be noted that the controller can adjust the power generation mode adopted by the wind and solar power generation device according to the user's instructions or automatically according to different wind speeds or sunlight conditions, and can also control the universal rotating head 5 and the wind turbine blades 4 to rotate to appropriate positions.

[0045] Furthermore, the wind and solar power generation device also includes a wind speed sensor (not shown). The wind speed sensor is used to detect wind speed and can be a mechanical wind speed sensor or an ultrasonic wind speed sensor. The wind speed sensor is located above the cylinder 2 or the power generation component. The wind speed sensor transmits the detected wind speed to the controller. The controller controls the wind turbine blades 4 to switch between open and closed positions according to the signal provided by the wind speed sensor. When the wind speed is less than a preset value, the wind turbine blades 4 are open. When the wind speed exceeds the preset value, the wind turbine blades 4 are closed. Thus, the wind turbine blades 4 are protected from the influence of strong winds to the greatest extent.
