A wind vane mechanism for a wind turbine generator set

Abstract

This utility model proposes a wind vane mechanism for a wind turbine generator set, relating to the field of wind vane technology. It includes a base, a support column, a base plate fixed to the bottom of the support column, and a fixing groove for securing the base plate. A connecting plate is fixed to the top of the support column. When the wind vane mechanism requires replacement of the wind vane tail fin and wind vane arrow, the limiting rod is pressed to align the clearance groove with the limiting ball. Then, the wind vane tail fin and wind vane arrow are pulled upwards until the mounting sleeve detaches from the fixing cylinder, thus disassembling the wind vane tail fin and wind vane arrow. Installation is similar: the mounting sleeve is first placed on the fixing cylinder, and then the limiting rod is pressed, causing the limiting ball to engage between the mounting sleeve and the fixing cylinder, thus securing the fixing cylinder and mounting sleeve. This device allows for quick replacement of the wind vane tail fin and wind vane arrow, reducing maintenance difficulty and cost.

Description

Technical Field

[0001] This utility model relates to a wind vane mechanism, specifically a wind vane mechanism for a wind turbine generator set, and belongs to the field of wind vane technology. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. It consists of a wind turbine, a generator, a tower, and a control system. The wind turbine receives wind energy and rotates, which drives the generator to produce electricity through a transmission system. The electricity is then optimized by the control system and connected to the power grid.

[0003] The wind vane mechanism is the "navigation core" for efficient energy capture in wind turbine generators. Its accurate wind direction identification provides real-time signals to the yaw system, ensuring the rotor is always aligned with the wind, thus preventing energy waste. If missing or malfunctioning, the generator's power generation efficiency can plummet due to wind misalignment, and component fatigue wear can be accelerated. It is crucial for balancing wind energy utilization and equipment lifespan, directly impacting the generator's economy and stability, and is a fundamental element of intelligent wind power system operation.

[0004] The wind vane mechanism, consisting of the wind vane tail fin and the wind vane arrow, is used to detect wind direction and drive the shaft to rotate, indicating the wind direction of the wind turbine generator. The tail fin and arrow are constantly exposed to harsh environments such as strong high-altitude winds, rain, snow, and dust storms, making them highly susceptible to corrosion, fatigue cracks, or deformation. Existing technologies often employ a one-piece molded structure; once the tail fin and arrow are damaged, they cannot be replaced individually, requiring the entire wind vane mechanism to be disassembled and replaced, resulting in high maintenance costs and cumbersome operations. Therefore, this paper proposes a wind vane mechanism for wind turbine generators. Utility Model Content

[0005] This invention proposes a wind vane mechanism for wind turbine generator sets, which enables quick replacement of the tail fin and wind vane arrow, reducing maintenance difficulty and cost.

[0006] This utility model is achieved through the following technical solution: a wind vane mechanism for a wind turbine generator set, including a base, the base including a support column, a base plate fixed to the bottom of the support column, a fixing groove provided on the base plate for fixing the base plate, a connecting plate fixed to the top of the support column, and a reinforcing plate fixed between the support column and the base plate.

[0007] It also includes a wind direction sensor component, which is mounted on the base. The wind direction sensor component includes a wind direction sensor body, and a fixing plate is fixed to the bottom of the wind direction sensor body. The fixing plate is fixed to the top of the connecting plate and is used to connect with the fixing plate. The wind direction sensor body is an existing device that can monitor wind direction.

[0008] It also includes a disassembly and assembly component, which is mounted on the wind direction sensor component. The disassembly and assembly component includes a fixed cylinder mounted on the wind direction sensor component, and a limit rod is provided inside the fixed cylinder. The disassembly and assembly component also includes a positioning post, which is fixed to the bottom of the limit rod. The positioning post is used to position the limit rod. When the positioning post abuts against the fixed cylinder, the position of the clearance groove corresponds to the limit ball. The disassembly and assembly component also includes a support sleeve, which is fixed on the fixed cylinder. The support sleeve can temporarily support the mounting sleeve and facilitate disassembly.

[0009] The fixed cylinder is fixed to the top of the wind direction sensor body. The limiting rod is slidably connected inside the fixed cylinder. A compression spring is fixed between the bottom of the limiting rod and the fixed cylinder. The limiting rod is set on the fixed cylinder through the compression spring. The elastic force generated by the elastic deformation of the compression spring can drive the limiting rod to reset. A limiting ball is movably set on the fixed cylinder. The limiting ball can move out of the fixed cylinder partly but cannot detach from the fixed cylinder. An avoidance groove is opened on the limiting rod to avoid the limiting ball.

[0010] It also includes a wind vane component, which is mounted on the disassembly and assembly component. The wind vane component includes a mounting sleeve, on which a rod is fixed. On the rod, a wind vane tail fin and a wind vane arrow are fixed. The disassembly and assembly component also includes a limiting hole, which is opened inside the mounting sleeve. When the wind blows on the wind vane tail fin, it will cause the wind vane tail fin, rod, mounting sleeve, and wind vane arrow to rotate, so that the length direction of the wind vane tail fin, wind vane arrow, and rod is aligned with the wind direction. At the same time, the fixing cylinder will also rotate under the drive of the mounting sleeve. Through the rotation of the fixing cylinder, in conjunction with the wind direction sensor body, the wind direction can be monitored in real time.

[0011] This utility model provides a wind vane mechanism for a wind turbine generator set, which has the following beneficial effects:

[0012] When the wind vane mechanism of this wind turbine needs to be replaced, press the limiting rod to align the clearance groove with the limiting ball, then pull the wind vane and wind vane upwards until the mounting sleeve disengages from the fixing cylinder, thus removing the wind vane and wind vane. Installation is similar: first, place the mounting sleeve on the fixing cylinder, then press the limiting rod to lock the limiting ball between the mounting sleeve and the fixing cylinder, thus securing the fixing cylinder and mounting sleeve. This device allows for quick replacement of the wind vane and wind vane, reducing maintenance difficulty and cost. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0023] Please see Figures 1-4 The present invention proposes the following implementation scheme: a wind vane mechanism for a wind turbine generator set, including a base 1, the base 1 including a support column 101, a base plate 102 fixed to the bottom of the support column 101, a fixing groove 103 provided on the base plate 102 for fixing the base plate 102, a connecting plate 105 fixed to the top of the support column 101, and a reinforcing plate 104 fixed between the support column 101 and the base plate 102.

[0024] Please refer to this carefully. Figure 1 and Figure 2 It also includes a wind direction sensor component 2, which is mounted on the base 1. The wind direction sensor component 2 includes a wind direction sensor body 201. A fixing plate 202 is fixed to the bottom of the wind direction sensor body 201. The fixing plate 202 is fixed to the top of the connecting plate 105. The connecting plate 105 is used to connect with the fixing plate 202. The wind direction sensor body 201 is an existing device that can monitor the wind direction.

[0025] Please refer to this carefully. Figure 2 and Figure 3 It also includes a disassembly and assembly component 3, which is installed on the wind direction sensor component 2. The disassembly and assembly component 3 includes a fixing cylinder 301 installed on the wind direction sensor component 2, a limit rod 302 installed inside the fixing cylinder 301, and a positioning post 307.

[0026] Please refer to this carefully. Figure 2 and Figure 3 The positioning post 307 is fixed to the bottom of the limiting rod 302. The positioning post 307 is used to position the limiting rod 302. When the positioning post 307 abuts against the fixed cylinder 301, the position of the clearance groove 305 corresponds to the limiting ball 303. The disassembly and assembly component 3 also includes a support sleeve 308. The support sleeve 308 is fixed on the fixed cylinder 301. The support sleeve 308 can temporarily support the mounting sleeve 401 and facilitate disassembly.

[0027] Please refer to this carefully. Figure 2 and Figure 3 The fixed cylinder 301 is fixed to the top of the wind direction sensor body 201. The limiting rod 302 is slidably connected inside the fixed cylinder 301. A compression spring 306 is fixed between the bottom of the limiting rod 302 and the fixed cylinder 301. The limiting rod 302 is set on the fixed cylinder 301 through the compression spring 306.

[0028] Please refer to this carefully. Figure 2 and Figure 3 The spring 306 can drive the limit rod 302 to reset through the elastic force generated by the elastic deformation. The fixed cylinder 301 is movably provided with a limit ball 303. The limit ball 303 can move out of the fixed cylinder 301 a part but cannot detach from the fixed cylinder 301. The limit rod 302 is provided with a relief groove 305, which is used to avoid the limit ball 303.

[0029] Please refer to this carefully. Figure 1 and Figure 4 It also includes a weather vane component 4, which is mounted on the disassembly and assembly component 3. The weather vane component 4 includes a mounting sleeve 401, on which a rod 402 is fixed. A weather vane tail wing 403 and a weather vane arrow 404 are fixed on the rod 402. The disassembly and assembly component 3 also includes a limiting hole 304, which is opened inside the mounting sleeve 401.

[0030] Please refer to this carefully. Figure 1 and Figure 4When the wind blows on the tail fin 403 of the weather vane, it will cause the tail fin 403, the rod 402, the mounting sleeve 401, and the wind vane arrow 404 to rotate, so that the length direction of the tail fin 403, the wind vane arrow 404, and the rod 402 is aligned with the wind direction. At the same time, the fixing cylinder 301 will also rotate under the drive of the mounting sleeve 401. Through the rotation of the fixing cylinder 301, in conjunction with the wind direction sensor body 201, the wind direction can be monitored in real time.

[0031] Working principle: When it is necessary to replace the weather vane tail 403 and weather vane arrow 404, press the limiting rod 302 so that the position of the clearance groove 305 corresponds to the limiting ball 303. Then, pull the weather vane tail 403 and weather vane arrow 404 upward. At this time, the mounting sleeve 401 will push the limiting ball 303 through the limiting hole 304, so that the limiting ball 303 moves into the clearance groove 305. At this time, the limiting ball 303 no longer limits the mounting sleeve 401. After the mounting sleeve 401 is separated from the fixing cylinder 301, the weather vane tail 403 and weather vane arrow 404 can be disassembled.

[0032] When installation is required, first put the mounting sleeve 401 on the fixing cylinder 301, then press the limiting rod 302 so that the position of the clearance groove 305 corresponds to the limiting ball 303. At this time, the mounting sleeve 401 can continue to move downward. Finally, release the limiting rod 302. Under the elastic force of the compression spring 306, the limiting rod 302 will return to its original position. The limiting rod 302 pushes the limiting ball 303 into the limiting hole 304 through the clearance groove 305, so that the limiting ball 303 is stuck between the mounting sleeve 401 and the fixing cylinder 301, thereby fixing the fixing cylinder 301 and the mounting sleeve 401. This device can quickly replace the weather vane tail fin 403 and the weather vane arrow 404, reducing maintenance difficulty and cost.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
