Description

[0002] As a clean energy, wind power generation does not produce greenhouse gases such as carbon dioxide in the power generation process compared to traditional fossil fuel power generation. It helps to reduce greenhouse gas emissions, can significantly reduce air pollution and improve air quality. It is of great significance to mitigate climate change, protect the ecological environment and alleviate the risks brought about by resource shortages.

[0003] The existing wind power generation device is mainly composed of a bracket, a wind rotor and a generator, wherein the wind rotor is rotatably arranged on the top of the bracket and is transmission-connected to the generator. When wind blows, it will drive the wind rotor on the top of the bracket to rotate, converting wind energy into mechanical energy, and then drive the rotor of the generator to rotate, converting mechanical energy into electrical energy, thereby achieving the purpose of wind power generation.

[0004] However, in existing wind power generation devices, it is difficult for traditional wind rotor blades to fully utilize wind energy at lower wind speeds, that is, the contact area between the blades and the wind is certain. When the wind is weak, part of the wind flows around the air outside the blades, making it difficult to drive the wind rotor to rotate and achieve the purpose of power generation.

[0047] One of the core aspects of the present invention is to provide a feather-like device. The structural design of the feather-like device enables the contact area between the blades and the wind to change with the wind speed when it is applied to the wind rotor blades of a wind power generation device, thereby improving the wind energy capture efficiency of the wind rotor of the wind power generation device and further improving the power generation efficiency.

[0048] Another core of the present invention is to provide a wind power generation device using the above-mentioned feather device.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0050] See also Figures 1 to 3 , Figure 1 It is a schematic diagram of the partial structure of a blade having a feather-shaped device provided by an embodiment of the present invention. Figure 2 for Figure 1 A partial enlarged schematic diagram of point A in the middle. Figure 3 It is a partially enlarged schematic diagram of a blade having a feather-like device provided by an embodiment of the present invention at the installation position of the feather-like device.

[0051] A feather device 200 is disclosed in an embodiment of the present invention. The feather device 200 is used for a blade 100 of a wind wheel of a wind power generation device. The blade 100 has a windward surface and a leeward surface. The distance between the windward surface and the leeward surface gradually decreases from the middle to both ends along the chord direction to form the leading edge and the trailing edge of the blade 100. The windward surface of the blade 100 is the part of the blade 100 facing the wind, which is mainly responsible for capturing wind energy and converting it into mechanical energy. The windward surface faces a higher wind speed, and the windward surface is generally convex, which can cause the airflow to produce a separation point on the surface of the blade 100 and accelerate the air to a certain extent, so that it can make full use of the wind energy.

[0052] The leeward side of the blade 100 is designed to reduce friction and air resistance when air flows over the surface of the blade 100, thereby avoiding wind energy loss due to excessive friction loss. The leeward side is generally a plane or concave surface with a relatively regular shape.

[0053] Specifically, the feather-like device 200 can be arranged on the windward side, the leeward side and at least one place inside the blade 100 of the blade 100. It should be noted that the feather-like device 200 can be installed on the surface of the blade 100, that is, no matter whether the feather-like device 200 is in the first position or the second position, the feather-like device 200 is completely protruding from the surface of the blade 100. When the feather-like device 200 is arranged inside the blade 100, that is, the feather-like device 200 is concealed, in the first position, the feather-like device 200 extends outward from the inside of the blade 100, and in the second position, the feather-like device 200 is completely embedded in the blade 100 or at least partially embedded in the blade 100. Of course, the shape and structure of the feather-like device 200 can be designed so that when it is in the second position, the surface of the blade 100 is a smooth curved surface without protrusions.

[0054] See also Figures 1 to 3 The feather device 200 includes a mounting base 210, a feather component 230 and a control component.

[0055] Among them, the mounting base 210 serves to fix the feather device 200 to the blade 100 and provide an installation position for the feather component 230 and the control component. The mounting base 210 includes a base body 211 and a first drive device. The base body 211 is used to be installed on the blade 100. The base body 211 and the blade 100 are connected by a fixed connection or a detachable connection. The fixed connection method includes but is not limited to welding and one-piece molding. The detachable connection method includes but is not limited to threaded fastener 300 connection and threaded connection.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the feather device 200 is installed on the blade 100 in an open-mounted manner through a threaded fastener 300. The threaded fastener 300 includes a stud 310 and a nut 320. A mounting through hole is provided on the surface of one side of the blade 100 near the leading edge and / or the trailing edge. The stud 310 is provided on the surface of the side of the base body 211 away from the feather assembly 230. The stud 310 passes through the mounting through hole and cooperates with the nut 320 to fix the base body 211 to the blade 100.

[0057] The first driving device is arranged on the base body 211, and the first driving device can drive the feather-shaped component 230 to move relative to the blade 100. The movement modes of the feather-shaped component 230 relative to the blade 100 include but are not limited to rotation, translation, and a combination of rotation and translation. It should be noted that the rotation axis of the feather-shaped component 230 relative to the blade 100 can be parallel or approximately parallel to the rotation plane of the wind wheel, or the rotation axis of the feather-shaped component 230 relative to the blade 100 can be vertical or approximately vertical to the rotation plane of the wind wheel. The translation of the feather-shaped component 230 relative to the blade 100 refers to the feather-shaped component 230 basically moving in a posture parallel to or approximately parallel to the rotation plane of the wind wheel.

[0058] The feather component 230 itself can adopt a foldable and / or retractable structure, or a non-foldable or retractable structure. One end of the feather component 230 is connected to the driving end of the first driving device, and the first driving device is used to drive the feather component 230 to reciprocate between the first position and the second position relative to the blade 100. When the feather component 230 is in the first position, the projection of the feather component 230 on the rotation plane of the wind wheel is at least partially located outside the projection of the blade 100 on the rotation plane of the wind wheel, so as to increase the windward area of ​​the blade 100. When the feather component 230 is in the second position, the projection of the feather component 230 on the rotation plane of the wind wheel is located within the projection of the blade 100 on the rotation plane of the wind wheel, so that the blade 100 has no additional windward area except the windward area of ​​its own windward surface.

[0059] When the blade 100 is provided with a plurality of the above-mentioned feather-like devices 200, the blade 100 and each feather-like device 200 form a structure similar to a bird's wing, that is, the blade 100 is equivalent to the wing of a bird, and the feather-like device 200 is equivalent to the feather of a bird. By adjusting the position of the feather-like device 200 relative to the blade 100, the overall windward area of ​​the blade 100 can be adjusted.

[0060] The control component includes a controller, an environment detection device and a status detection device. The environment detection device is used to detect preset environmental information, which includes but is not limited to wind direction and wind speed. The status detection device is used to detect preset status information of the feather component 230, which includes but is not limited to position, temperature, and vibration. The controller is used to control the working state of the first drive device according to the detection information of the environment detection device and the status detection device.

[0061] See also Figure 3 In one embodiment of the present application, the controller and the first driving device are integrated into a control box 220 located on one side of the base body 211.

[0062] When in use, the environmental detection device detects the environmental wind speed and / or wind direction in real time. When the information obtained by the controller meets the preset expansion requirements, the controller controls the first drive device to move the feather component 230 to the first position to increase the windward area of ​​the blade 100. Of course, the first position is not a fixed position. The controller can control the specific position of the feather component 230 according to the detected information and the preset instructions to adjust the windward area of ​​the blade 100 according to the environmental information, that is, when the feather component 230 is in the first position, the size of the part of the projection of the feather component 230 on the rotation plane of the wind wheel that is located outside the projection of the blade 100 on the rotation plane of the wind wheel is adjustable to change the windward area of ​​the blade 100 according to the environmental information. When the information obtained by the controller meets the preset folding requirements, the controller controls the first drive device to move the feather component 230 to the second position to minimize the windward area of ​​the blade 100 and avoid excessive wind resistance affecting equipment safety.

[0063] Compared with the prior art, the feather device 200 provided in the embodiment of the present invention enables the windward area of ​​the blade 100 of the wind power generation device to change with environmental changes, and regulates the effective force-bearing area of ​​the blade 100 in real time, thereby avoiding the problem that at lower wind speeds, part of the wind force bypasses the air flow outside the blade 100, making it difficult to drive the wind wheel to rotate, thereby reducing wind energy loss, better capturing wind energy, and effectively improving power generation efficiency.

[0064] In a specific embodiment of the present application, Figure 3 and Figure 4 As shown, the feather component 230 is rotatably arranged on the base body 211, wherein the first driving device includes a rotating shaft 213 and a rotating driver, wherein the rotating shaft 213 is rotatably arranged on the base body 211, one end of the feather component 230 is fixedly arranged on the rotating shaft 213, the rotating driver is arranged on the base body 211 and is transmission-connected with the rotating shaft 213, the rotating driver drives the feather component 230 to reciprocate between the first position and the second position through the rotating shaft 213, and the rotating driver is communicated with the controller. Then, during installation, the axis of the rotating shaft 213 is parallel or approximately parallel to the rotation plane of the wind wheel, so that the angle between the feather component 230 and the rotation plane of the wind wheel is adjustable. In practical applications, this arrangement of the rotating shaft 213 not only makes the projection position of the feather component 230 on the rotation plane of the wind wheel adjustable relative to the projection position of the blade 100 on the rotation plane of the wind wheel, but also can adjust the angle between the feather component 230 and the rotation plane of the wind wheel according to the change of wind direction, so as to adapt to the change of wind direction more flexibly and improve the wind energy capture efficiency.

[0065] The rotary driver includes a rotary motor and a reduction mechanism. The motor shaft of the rotary motor is connected to the rotating shaft 213 through the reduction mechanism. The reduction mechanism is used to reduce speed and increase torque. The rotary motor includes but is not limited to a stepper motor and a servo motor.

[0066] To facilitate the installation of the feather assembly 230 and the flipping relative to the blade 100, in one embodiment of the present application, as shown in FIG. Figure 3 and Figure 4 As shown, the base body 211 is provided with an open mounting groove 212, and the open mounting groove 212 includes a bottom groove wall and side groove walls arranged opposite to the bottom groove wall. The two ends of the rotating shaft 213 are rotatably arranged on the side groove walls arranged opposite to each other in the open mounting groove 212, and one end of the feather-shaped component 230 connected to the rotating shaft 213 can be at least partially embedded in the open mounting groove 212, so that the installation of the rotating shaft 213 is convenient, and the open mounting groove 212 can also be used to limit the feather-shaped component 230 to a certain extent to maintain its stability.

[0067] Please refer to Figure 3 and Figure 5 In one embodiment of the present application, the feather component 230 adopts a retractable structure, and the feather component 230 includes a base member 231 and an end member 232, wherein the base member 231 and the end member 232 are both made of a lightweight material with a certain elasticity, such as glass fiber. The first end of the base member 231 along the length direction of the feather component 230 is connected to the driving end of the first driving device, and the length direction of the feather component 230 refers to the direction from the end connected to the first driving device to the direction away from the first driving device. The second end of the base member 231 along the length direction of the feather component 230 is connected to the end member 232 through the second driving device 2323, and the second driving device 2323 is used to drive the end member 232 to reciprocate relative to the base member 231 along the length direction of the feather component 230, that is, in the above embodiment, the feather component 230 is retractable in the length direction.

[0068] In order to improve the stability of the base member 231 and the end member 232 when they move relative to each other, in one embodiment of the present application, Figure 5 As shown, one of the base member 231 and the end member 232 is provided with a slide groove, and the other of the base member 231 and the end member 232 is partially slidably embedded in the slide groove. Through the slide groove of one of the base member 231 and the local sliding cooperation of the other, the base member 231 and the end member 232 can be guided and limited during the relative movement of the base member 231 and the end member 232, thereby improving the stability of the base member 231 and the end member 232 during relative movement and the connection strength between the base member 231 and the end member 232.

[0069] See also Figure 6The end member 232 includes a sliding connection portion 2321 and a tip portion 2322. The tip portion 2322 is detachably connected to the first end of the sliding connection portion 2321 along the length direction of the feather-shaped component 230. Of course, it should be noted that the tip portion 2322 can also be an integral structure with the sliding connection portion 2321. The second end of the sliding connection portion 2321 along the length direction of the feather-shaped component 230 is provided with a slide groove or is partially slidably embedded in the slide groove provided on the base member 231.

[0070] Specifically, in Figure 6 In the illustrated embodiment, the base member 231 is provided with a slide groove recessed toward the rotation axis 213 , and the sliding connection portion 2321 of the end member 232 is slidably embedded in the slide groove, and one end of the sliding connection portion 2321 extending out of the slide groove is connected to a tip portion 2322 .

[0071] like Figure 6 As shown, the second drive device 2323 is an electric push rod. Of course, the second drive device 2323 can also adopt other structures. For example, the second drive device 2323 can be a piston cylinder, such as a pneumatic cylinder or a hydraulic cylinder, or it can be composed of a rotating motor and a transmission mechanism. The transmission mechanism is used to convert the rotation output by the rotating motor into a linear reciprocating motion. The transmission mechanism includes but is not limited to a gear rack mechanism, a screw slider mechanism, and a cam connecting rod mechanism.

[0072] Further optimize the above technical solution, such as Figure 5 As shown, the feather component 230 also includes an expandable component 233, which is arranged on at least one side surface of the base member 231. The expandable component 233 can expand or contract to increase or decrease the size of the feather component 230 in at least one direction of the width direction and the thickness direction. The width direction of the feather component 230 is a direction parallel to the axis of the rotating shaft 213, and the thickness direction of the feather component 230 is a direction perpendicular to the axis of the rotating shaft 213 and the length direction of the feather component 230. By adjusting the thickness and / or width direction of the feather component 230 through the expandable component 233, it is possible to more flexibly adapt to changes in wind speed and wind direction, thereby improving the wind energy capture efficiency.

[0073] Specifically, see Figure 7In one embodiment of the present application, the expandable component 233 includes a first expansion member 2331 and a second expansion member 2332, wherein the first expansion member 2331 includes a first airbag 23311 and a first inflation and deflation device 23312, the first airbag 23311 is detachably arranged on at least one side surface of the base member 231 along the thickness direction of the feather-shaped component 230, the first inflation and deflation device 23312 is arranged on the base body 211 and is connected to the first airbag 23311, the first inflation and deflation device 23312 can inflate and deflate the first airbag 23311 to increase or decrease the size of the feather-shaped component 230 in the thickness direction, thereby realizing the adjustment of the size of the feather-shaped component 230 in the thickness direction.

[0074] The second expansion member 2332 includes a second airbag 23321 and a second inflation and deflation device 23322. The second airbag 23321 is detachably arranged on at least one side surface of the base member 231 and / or the first airbag 23311 along the width direction of the feather-shaped component 230. The second inflation and deflation device 23322 is connected to the second airbag 23321. The second inflation and deflation device 23322 can inflate and deflate the second airbag 23321, thereby achieving adjustment of the size of the feather-shaped component 230 in the width direction.

[0075] exist Figure 7 In the illustrated embodiment, second airbags 23321 are respectively provided on both sides of the first airbag 23311 in the width direction. The first airbag 23311 and the second airbag 23321 are flexible structures, which are wrapped around other structures of the feather-shaped assembly 230 and can protect other components of the feather-shaped assembly 230 and the blade 100, that is, they can absorb part of the wind impact and protect the blade 100 and the feather-shaped assembly 230 from colliding with each other and being damaged under the action of wind impact.

[0076] The structural design of the expandable component 233 composed of the airbag and the inflation and deflation device is relatively simple and easy to maintain. By regularly checking and replacing wearing parts such as the airbag, the life of the entire wind power generation device can be extended and the maintenance cost can be reduced.
