Description

Technical Field

[0001] This invention relates to the field of renewable energy utilization technology, and in particular to a self-cleaning power generation device. 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. Wind turbines generally convert wind energy into kinetic energy through wind turbine blades, and then use generators to convert kinetic energy into electrical energy and transmit it to the power grid. However, the wind turbine blades of wind turbines are very long and have a large area, and inevitably they will be covered with pollutants such as dust, snow, or bird droppings. Excessive accumulation of these pollutants will affect the normal operation of the wind turbine blades and easily lead to mechanical failures. Currently, the only way to clean the pollutants on wind turbine blades is by manual cleaning, which is not only risky but also has very low cleaning efficiency. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a self-cleaning power generation device.

[0005] The self-cleaning power generation device of this invention includes a base, a cylinder, a nacelle, a power generation component, and multiple wind turbine blades. The lower end of the cylinder is connected to the base, the nacelle is located at the upper end of the cylinder, the power generation component is located inside the nacelle, and the wind turbine blades are rotatably connected to the power generation component. Thin-film solar panels are provided on the outer surface of the wind turbine blades and / or the outer circumferential surface of the cylinder. Both the wind turbine blades and the solar panels are connected to the power generation component. The wind turbine blades can be switched between an open position and a closed position. In the open position, the wind turbine blades can be used to generate electricity. In the closed position, multiple wind turbine blades are stacked. At least a portion of the front surface and / or at least a portion of the back surface of the wind turbine blades are provided with brushes. During the process of switching the wind turbine blades from the open position to the closed position or from the closed position to the open position, the brushes can brush away contaminants on adjacent wind turbine blades.

[0006] The self-cleaning power generation device of this invention provides a self-cleaning function by setting brushes on the wind turbine blades and making the wind turbine blades rotatable. This eliminates the need for high-risk manual cleaning methods, and the entire cleaning process can be completed by rotating the wind turbine blades a few times, resulting in high cleaning efficiency.

[0009] In some embodiments, the first power generation component includes a generator and a connector connected to the input shaft of the generator, and the wind turbine blades are connected to the connector.

[0010] In some embodiments, one end of the fan blade is rotatably connected to the connector, and the fan blade is circumferentially rotatable along the connector to switch between the open position and the closed position.

[0021] 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.

[0022] The self-cleaning power generation device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the self-cleaning 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.

[0024] 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.

[0025] The nacelle 3 is located at the upper end of the cylinder 2, the power generation component is located inside the nacelle 3, the fan blades 4 are rotatable and connected to the power generation component, the fan blades 4 can be switched between an open position and a closed position. In the open position, the fan blades 4 can be used to generate electricity. In the closed position, multiple fan blades 4 are stacked. At least a portion of the front surface and / or at least a portion of the back surface of the fan blades 4 are provided with brushes (not shown). During the process of switching the fan blades 4 from the open position to the closed position or from the closed position to the open position, the brushes can brush away contaminants on adjacent fan blades 4.

[0026] It is understood that the wind turbine blade 4 in this embodiment of the invention can be opened or closed. When in the open position, the wind turbine blade 4 can generate wind power normally. When the wind turbine blade is contaminated with pollutants, it can be switched between the open and closed positions. During the switching process, the brush on one wind turbine blade 4 will brush away the pollutants on the adjacent wind turbine blade 4, thereby achieving the purpose of cleaning the wind turbine blade 4. When one switching cannot completely clean it, it can be switched between the open and closed positions multiple times until the cleaning is completed.

[0027] In addition, when the wind turbine blade 4 is in the closed position, the area of ​​the wind-facing surface of the wind turbine blade 4 can be reduced. When there is a storm or other severe weather, the wind turbine blade 4 can be switched to the closed position to effectively prevent the wind turbine blade from being easily damaged, thus improving the reliability of the power generation device.

[0028] The self-cleaning power generation device of this invention provides a self-cleaning function by setting a brush on the wind turbine blade 4 and making the wind turbine blade 4 rotatable. This eliminates the need for high-risk manual cleaning methods, and the entire cleaning process can be completed by rotating the wind turbine blade 4 a few times, resulting in high cleaning efficiency.

[0029] 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. It is understood that the power generation device of this embodiment 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 the thin-film solar panels provided on the outer surface of the wind turbine blades 4 and / or the outer circumferential surface of the cylinder 2. The two power generation systems can operate independently or simultaneously. For example, in seasons with strong winds and abundant sunshine, wind and solar power generation can be used simultaneously. In seasons with weak winds but abundant sunshine, compared to traditional wind power generation or solar power generation, the power generation device of this embodiment has higher power generation efficiency, better stability, and a wider range of applications.

[0030] Preferably, the back surface of the fan blade 4 is provided with a brush, and the front surface of the fan blade 4 is provided with a solar panel. This arrangement can simultaneously realize the functions of solar power generation and self-cleaning, thus improving the practicality of the power generation device.

[0031] 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.

[0032] 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.

[0033] like Figure 1As shown, in some embodiments, the first power generation component includes a generator and a connector 5 connected to the input shaft 6 of the generator. One end of a wind turbine blade 4 is rotatably connected to the connector 5, and the wind turbine blade 4 is circumferentially rotatable along the connector 5 to switch between an open position and a closed position.

[0034] In some embodiments, such as Figure 2 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 connector 5, and one end of the second blade segment 42 is rotatably connected to the other end of the first blade segment 41.

[0035] The first leaf segment 41 can rotate around the circumference of the connector 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.

[0036] It should be noted that when the power generation device generates wind power, the second blade segments 42 of the 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 power generation device only generates solar power, the second blade segments 42 of the multiple wind turbine blades 4 can be made parallel to each other to increase the light-receiving area of ​​the wind turbine blades 4.

[0037] Specifically, the open positions of the wind turbine blades 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 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.

[0038] It should be noted that when cleaning the fan blades 4, the fan blades 4 should first be rotated from the first open position to the second open position, and then switched from the second open position to the closed position. Correspondingly, after cleaning is completed, the fan blades 4 should first be switched from the closed position to the second open position, and then switched from the second open position to the first open position.

[0039] In some embodiments, the nacelle 3 is rotatably disposed on the upper end of the cylinder 2 along the circumference of the cylinder 2, thereby allowing the fan blades 4 to face the wind or the sun at the most appropriate angle by rotating the nacelle 3.

[0040] Furthermore, the power generation device in this embodiment of the invention also includes a solar tracking and positioning component (not shown). The solar tracking and positioning component is used to determine the position of the sun. The nacelle 3 can rotate toward the direction of the sun according to the signal provided by the solar tracking and positioning component. In seasons with weak winds, the wind turbine blades 4 can be aligned with the sun, thereby improving the efficiency of solar power generation.

[0041] It should be noted that the solar tracking positioning system is a mature existing technology, such as a fixed solar tracker (SOLYS Gear Drive). This tracker is a solar tracker that can be deployed in all weather and all directions. The solar tracking positioning component in the embodiments of the present invention can be selected from this tracker or other solar trackers.
