Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a wind vane alignment device for a wind turbine generator set. Background Technology

[0002] For wind turbines, when aligning with the wind direction, an alignment device needs to be installed on the generator casing, and then the wind vane is used to determine the wind direction.

[0003] CN205787404U discloses a wind vane alignment device for a wind turbine generator, which directly mounts the alignment device onto the wind turbine casing. CN216241104U discloses an intelligent wind turbine generator wind vane device, which also directly mounts the device onto the wind turbine casing. However, both of these existing technologies have the following drawbacks: the wind turbine casing is not planar, making installation and disassembly inconvenient via direct connection; and the wind vane cannot be aligned with the centerline of the turbine blade shaft, meaning the monitored wind direction does not directly reflect the wind direction corresponding to the wind turbine rotor, resulting in a certain degree of deviation. Summary of the Invention

[0004] The purpose of this invention is to provide a wind vane alignment device for wind power generation units to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wind vane alignment device for a wind turbine generator includes a base, a wind vane, a bracket, a support plate, and an alignment assembly. The wind vane is rotatably mounted on the base, wherein:

[0007] Both ends of the base are hinged to brackets, and support plates are hinged to the brackets. Electromagnet I is provided at the bottom of the support plate. The alignment assembly includes a winding wheel, a rope, an electromagnet II, and a motor. The two winding wheels are rotatably mounted on the base via a rotating shaft driven by a motor. The winding wheels are wound with ropes, and the other end of the ropes is connected to the electromagnet II. The two ropes are wound in opposite directions. When the rotating shaft rotates, the two winding wheels unwind or wind simultaneously.

[0008] Preferably, the alignment device further includes a storage assembly for storing the two electromagnets II.

[0009] Preferably, the base has sleeves on both sides, and a telescopic rod is installed inside the sleeve, wherein the bracket is hinged to the end of the telescopic rod.

[0010] Preferably, the storage assembly includes a linear drive mechanism, a horizontal support, and forks. The linear drive mechanism is mounted on the base, the horizontal support is mounted on the actuating component of the linear drive mechanism, and forks are provided on both sides of the horizontal support. The forks are located below the rope and can pull up the rope when the forks are raised.

[0011] Preferably, the linear drive mechanism consists of a linear guide rail and a linear motor, wherein the linear guide rail is vertically connected to the base, the linear motor is mounted on the linear guide rail, and the horizontal bracket is connected to the linear motor.

[0012] Preferably, a limiting bolt is provided in the threaded hole on the sleeve, wherein the end of the limiting bolt contacts the telescopic rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, a motor drives two winding wheels to rotate, thereby winding up the two ropes. At this time, the electromagnet II is attracted to the wind turbine casing, and the synchronously wound ropes will drive the entire alignment device to move, so that the alignment device is at the center of the wind turbine casing, thereby achieving center alignment.

[0015] 2. The present invention uses electromagnet I as a connecting component to the wind turbine, and electromagnet I has three degrees of freedom in three directions, thus being able to adapt to wind turbine housings of different shapes. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example:

[0023] Please see Figures 1 to 4 The present invention provides a technical solution:

[0024] A wind vane alignment device for a wind turbine generator includes a base 1, a wind vane 2, a bracket 3, a support plate 4, and an alignment assembly 5.

[0025] The wind vane 2 is rotatably mounted on the base 1, and the wind direction is determined by the wind vane 2. Both ends of the base 1 are hinged to the brackets 3, and the brackets 3 are hinged to the support plates 4. The bottom of the support plates 4 is equipped with an electromagnet I 41. As the electromagnet I 41 is in direct contact with the wind turbine shell, it has two degrees of freedom, so it can adapt to the non-planar wind turbine shell. The alignment component 5 includes a winding wheel 51, a rope 52, an electromagnet II 53, and a motor 54. The two winding wheels 51 are rotatably mounted on the base 1 through a rotating shaft, which is driven by the motor 54. Specifically, the motor 54 is mounted on the base 1 by bolts, and the power output end of the motor 54 is connected to the rotating shaft. The rope 52 is wound on the winding wheel 51, and the other end of the rope 52 is connected to the electromagnet II 53. The two ropes 52 are wound in opposite directions. When the rotating shaft rotates, the two winding wheels 51 unwind or wind up at the same time, thereby achieving the effect of centering the base 1 on the wind turbine shell.

[0026] In a preferred embodiment, the alignment device further includes a housing component 6, which is used to house the two electromagnets II 53, thereby preventing electromagnet I 41 from attracting electromagnet II 53 when energized, and enabling electromagnet II 53 to quickly detach from the wind turbine housing.

[0027] In a preferred embodiment, sleeves 11 are provided on both sides of the base 1, and telescopic rods 12 are installed inside the sleeves 11, with the bracket 3 hinged to the end of the telescopic rod 12. Therefore, the distance between the two support plates 4 can be adaptively adjusted to accommodate wind turbine housings of different sizes, increasing the degree of freedom of the electromagnet I 41.

[0028] In a preferred embodiment, the storage component 6 includes a linear drive mechanism, a horizontal support 61, and a fork plate 62. The linear drive mechanism is mounted on the base 1, and the horizontal support 61 is mounted on the execution component of the linear drive mechanism. Fork plates 62 are provided on both sides of the horizontal support 61, with the fork plates 62 located below the rope 52. When the fork plates 62 are raised, they can pull up the rope 52, thereby lifting the electromagnet II 53.

[0029] In a preferred embodiment, the linear drive mechanism consists of a linear guide rail 63 and a linear motor 64. The linear guide rail 63 is vertically connected to the base 1, and the linear motor 64 is mounted on the linear guide rail 63. The horizontal bracket 61 is connected to the linear motor 64. This embodiment discloses one linear drive method, but it can also be a helical transmission pair or a gear and rack transmission pair. Therefore, the linear drive mechanism is not limited to the solution disclosed in this embodiment.

[0030] In a preferred embodiment, a limiting bolt 13 is provided in the threaded hole on the sleeve 11, wherein the end of the limiting bolt 13 contacts the telescopic rod 12, thereby limiting the telescopic rod 12. Of course, the limiting method is not limited to bolt limiting, but can also be pin limiting.

[0031] The operating principle of this invention is as follows: The base 1 is placed directly on the wind turbine's outer casing. Electromagnet I 41 acts as a support component for the base 1. The motor 54 drives the shaft to rotate, causing the two winding wheels 51 to unwind the rope 52. Then, electromagnet II 53 is attracted to the side of the wind turbine's outer casing. Next, the motor 54 drives the shaft to reverse, causing the two winding wheels 51 to wind up the rope 52. Since the two ropes 52 wind up synchronously, when the base 1 is tilted to one side of the wind turbine, the rope 52 will pull it to the center of the wind turbine's outer casing, thus aligning the wind vane 2 with the wind turbine's impeller shaft. The central axes are on the same vertical plane, thus achieving alignment. When the wind vane 2 monitors the wind direction, it can directly reflect the wind direction position of the impeller. Then, the electromagnet I 41 is energized, and the electromagnet I 41 is attracted to the wind turbine housing. Since the electromagnet I 41 has multiple degrees of freedom, it ensures a high degree of fit between the electromagnet I 41 and the wind turbine housing. At this time, the electromagnet II 53 is de-energized, and the linear motor 64 drives the fork plate 62 to move upward. When the fork plate 62 rises, it can pull up the rope 52, and then the raised fork plate 62 can lift the electromagnet II 53, thus realizing the storage of the electromagnet II 53.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
