Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, and in particular to a wind direction indicator zeroing device for wind turbine units. Background Technology

[0002] The power generation and safe operation of wind turbines are highly dependent on precise control of the wind angle. As the wind direction constantly changes, the turbine needs to yaw in real time to maximize wind energy capture and ensure safe operation. Therefore, the initial zeroing (calibration of the zero point) of the anemometer (or weather station) is crucial.

[0003] Currently, wind vanes commonly use the "visual zeroing method," which involves calibrating the vane by visually observing the orientation of the markings on it. However, this method relies on manual judgment, and errors can easily occur depending on the operator. If the error is too large, it can reduce power generation efficiency, or even cause serious accidents such as tower collapse due to angular deviations during extreme weather events like typhoons.

[0004] Furthermore, wind vanes are divided into two types: mechanical and ultrasonic. While their appearances differ significantly, both are core components of wind turbine systems. Products from different manufacturers also vary in structure and interface. Therefore, there is an urgent need for a versatile and easy-to-operate wind turbine zeroing device that is compatible with various wind vane types, enabling rapid and accurate calibration, and fundamentally improving the wind alignment accuracy and operational safety of the turbine.

[0043] This invention provides a wind turbine wind direction indicator zeroing device, which can be used for zeroing the wind direction indicator. Figures 1 to 3 This invention illustrates a preferred embodiment of the wind turbine wind direction indicator zeroing device provided by this utility model.

[0044] Please see Figures 1 to 3 In some embodiments, the wind turbine wind direction indicator zeroing device 100 includes a device body 1, a pressing member 2, a connecting rod 4, a first bracket 5, and a second bracket 6. The pressing member 2 is horizontally spaced from the device body 1, and a slot 3 extending vertically is provided through the pressing member 2 and / or the device body 1. Two connecting rods 4 are horizontally spaced between the pressing member 2 and the device body 1, and the pressing member 2 is adjustable relative to the device body 1 by moving along the connecting rods 4.

The second bracket 6 is disposed on the device body 1 or the pressing member 2, and the second bracket 6 has an upward-facing slot. The limiting groove 61 extends through the second bracket 6 in the extension direction of the connecting rod 4; wherein, when the wind turbine wind direction indicator zeroing device 100 is installed on the ultrasonic wind direction indicator 300, the pressing member 2 and the device body 1 respectively abut against the two sides of the ultrasonic wind direction indicator 300 in the extension direction of the connecting rod 4, and the slot 3 and the support rod 310 of the ultrasonic wind direction indicator 300 form a snap-fit ​​engagement; when the wind turbine wind direction indicator zeroing device 100 is installed on the mechanical wind direction indicator 400, the pressing member 2 and the device body 1 respectively abut against the two sides of the mechanical wind direction indicator 400 in the extension direction of the connecting rod 4, and the pointing rod 410 of the mechanical wind direction indicator 400 passes through the second bracket 6 from the limiting groove 61.

[0045] Specifically, two connecting rods 4 are disposed between the main body 1 and the pressing member 2. The two connecting rods 4 are spaced apart in the horizontal direction, and both connecting rods 4 extend in the horizontal direction. The spacing direction of the two connecting rods 4 is defined as left-right, and the extension direction of the connecting rods 4 is defined as front-back. The end of the connecting rod 4 closer to the pressing member 2 is the front end of the connecting rod 4, and the end of the connecting rod 4 closer to the main body 1 is the rear end of the connecting rod 4.

[0046] The front and rear ends of the connecting rod 4 are respectively disposed on the pressing member 2 and the device body 1, and the front end of the connecting rod 4 is movably connected to the pressing member 2 so that the pressing member 2 can move back and forth relative to the device body 1 along the connecting rod 4, thereby adjusting the distance between the device body 1 and the pressing member 2 in the front and back upward.

[0047] The slot 3 can be provided only on the main body 1 of the device, and the slot 3 penetrates the main body 1 vertically upwards; the slot 3 can also be provided only on the pressing member 2, and the slot 3 penetrates the pressing member 2 vertically upwards; the slot 3 can also be provided on both the main body 1 of the device and the pressing member 2. The following description will use the example of slots 3 penetrating both the main body 1 and the pressing member 2 vertically. The slot 3 can be an arc-shaped slot or a square slot, etc. The following description will use an arc-shaped slot 3 as an example.

[0048] The first bracket 5 can be mounted on the main body 1 of the device, or it can be mounted on the pressing member 2. The following description will use the example of the first bracket 5 being mounted on the main body 1 of the device. The first bracket 5 is used to mount the laser emitter 200, allowing the laser emitter 200 to be mounted on the first bracket 5 along the front-to-back direction. The laser emitter 200 may be part of the wind turbine wind direction indicator zeroing device 100, meaning the wind turbine wind direction indicator zeroing device 100 includes the laser emitter 200; alternatively, the laser emitter 200 may not be part of the wind turbine wind direction indicator zeroing device 100, meaning the wind turbine wind direction indicator zeroing device 100 does not include the laser emitter 200.

[0049] The second support 6 can be installed on the main body 1 of the device, or it can be installed on the pressing member 2. The following description will take the case where the second support 6 is installed on the main body 1 of the device as an example. The upper end of the second support 6 extends upward beyond the main body 1 of the device, and the upper end of the second support 6 is provided with a limiting groove 61 with the opening facing upward. The limiting groove 61 passes through the second support 6 from front to back upward.

[0050] The wind turbine wind vane zeroing device 100 can be installed on the ultrasonic wind vane 300 to zero the ultrasonic wind vane 300; the wind turbine wind vane zeroing device 100 can also be installed on the mechanical wind vane 400 to zero the mechanical wind vane 400.

[0051] The ultrasonic wind vane 300 has multiple support rods 310 extending vertically in the middle, which connect the upper and lower parts of the ultrasonic wind vane 300. The following will describe an example of an ultrasonic wind vane 300 with four support rods 310 evenly spaced in the middle. When the wind turbine wind direction indicator zeroing device 100 is installed on the ultrasonic wind direction indicator 300, the wind turbine wind direction indicator zeroing device 100 is sleeved on the outside of the middle part of the ultrasonic wind direction indicator 300. The two connecting rods 4 are located on the left and right sides of the ultrasonic wind direction indicator 300, respectively. The pressing part 2 abuts against the front side of the middle part of the ultrasonic wind direction indicator 300, and the device body 1 abuts against the rear side of the middle part of the ultrasonic wind direction indicator 300. The slots 3 on the device body 1 and the pressing part 2 respectively form a snap-fit ​​engagement with multiple support rods 310, thereby realizing the fixed installation of the wind turbine wind direction indicator zeroing device 100 on the ultrasonic wind direction indicator 300. At this time, the laser emitter 200 on the wind turbine wind direction indicator zeroing device 100 zeros the ultrasonic wind direction indicator 300.

[0052] The mechanical wind vane 400 includes a pointing rod 410 and a main body 420. The main body 420 extends vertically, and the pointing rod 410 is located at the upper end of the main body 420. When the wind turbine wind vane zeroing device 100 is installed on the mechanical wind vane 400, the wind turbine wind vane zeroing device 100 is sleeved on the outside of the main body 420. The two connecting rods 4 are located on the left and right sides of the main body 420, respectively. The pressing member 2 abuts against the front side of the main body 420, and the device body 1 abuts against the rear side of the main body 420. The front end of the pointing rod 410 passes forward from the limiting groove 61 through the second bracket 6, so that the pointing rod 410 and the limiting groove 61 form a snap-fit ​​engagement, thereby fixing the wind turbine wind vane zeroing device 100 on the ultrasonic wind vane 300. At this time, the laser emitter 200 on the wind turbine wind vane zeroing device 100 zeroes the ultrasonic wind vane 300. The specific shape of the limiting groove 61 can be set according to the actual situation. Optionally, please refer to Figures 1 to 3 In some embodiments, the limiting groove 61 is a V-shaped groove that is wider at the top and narrower at the bottom. Setting the limiting groove 61 as a V-shaped groove is beneficial for the limiting groove 61 to form a snap-fit ​​with the guide rods 410 of different thicknesses. The following will describe the limiting groove 61 as a V-shaped groove as an example.

[0053] The wind turbine wind direction indicator zeroing device 100 has the advantages of wide versatility, strong operability, and high reliability.

[0054] The wind turbine wind vane zeroing device 100 of this utility model is compatible with both ultrasonic wind vane 300 and mechanical wind vane 400, and can be adapted to wind vanes of different models and sizes, making it highly versatile. It is small, lightweight, easy to operate, and portable, and can significantly improve the zeroing accuracy of the wind vane on site.

[0055] Both the first bracket 5 and the second bracket 6 are disposed on the main body 1 of the device. The first bracket 5 may be located on the left side of the main body 1, while the second bracket 6 may be located on the right or rear side of the main body 1; alternatively, the first bracket 5 may be located on the right side of the main body 1, while the second bracket 6 may be located on the left or rear side of the main body 1. Alternatively, please refer to... Figures 1 to 3 In some embodiments, the first bracket 5 and the second bracket 6 are respectively disposed on both sides of the device body 1 in the interval direction of the two connecting rods 4.

[0056] Specifically, one of the first bracket 5 and the second bracket 6 is located on the left side of the device body 1, and the other is located on the right side of the device body 1. This facilitates the installation of the first bracket 5 and the second bracket 6 on the device body 1. Hereinafter, the side of the device body 1 closer to the first bracket 5 is defined as the left side of the device body 1, and the side of the device body 1 closer to the second bracket 6 is defined as the right side of the device body 1. Thus, the first bracket 5 is located on the left side of the device body 1, and the second bracket 6 is located on the right side of the device body 1.

[0057] The first bracket 5 can be used to fix the laser emitter 200. The specific configuration of the first bracket 5 can be set according to the actual situation. Optionally, please refer to Figures 1 to 3 In some embodiments, the upper surface of the first bracket 5 is provided with a receiving groove 51 for accommodating the laser emitter 200. The receiving groove 51 extends through the first bracket 5 in the extending direction of the connecting rod 4. The upper surface of the first bracket 5 is provided with a limiting ring 52 that can be adjusted up and down. The limiting ring 52 is used to abut against the upper side of the laser emitter 200.

[0058] Specifically, the upper surface of the first support 5 is provided with an upward-facing receiving groove 51, which extends through the first support 5 from front to back upward. The laser emitter 200 can be placed inside the receiving groove 51. The specific shape of the receiving groove 51 can be set according to the actual situation. Optionally, please refer to Figures 1 to 3 In some embodiments, the receiving groove 51 is a V-shaped groove that is wider at the top and narrower at the bottom. By setting the receiving groove 51 as a V-shaped groove, the receiving groove 51 can accommodate laser emitters 200 of different thicknesses. The following will describe the receiving groove 51 as a V-shaped groove as an example.

[0059] The limiting ring 52 can be circular or similar in shape. It is adjustable up and down on the upper surface of the first bracket 5, with a portion of the limiting ring 52 vertically aligned with the opening of the receiving groove 51. After the laser emitter 200 is placed in the receiving groove 51, the limiting ring 52 is adjusted downwards so that the portion of the limiting ring 52 aligned with the opening of the receiving groove 51 abuts against the upper side of the laser emitter 200. This positions the laser emitter 200, thus fixing it to the first bracket 5. The limiting ring 52 can be connected to the first bracket 5 via a bottom pin extending vertically, allowing it to move up and down relative to the first bracket 5.

[0060] Optionally, please refer to Figures 1 to 3 In some embodiments, the first bracket 5 is rotatably and adjustably mounted on the device body 1 along the axis of the interval between the two connecting rods 4.

[0061] Specifically, the first bracket 5 can be rotated and adjusted relative to the main body 1 along a left-right upward axial direction, thereby driving the laser emitter 200 on it to rotate and adjust together. The first bracket 5 is connected to the main body 1 via a rotating shaft extending left-right, and a second wing nut 53 is provided on the first bracket 5. Loosening the second wing nut 53 allows the first bracket 5 to rotate freely to adjust the angle of the laser emitter 200. After adjusting the angle of the laser emitter 200, tightening the second wing nut 53 achieves a fixed connection between the first bracket 5 and the main body 1.

[0062] The specific shape and style of the second bracket 6 can be set according to the actual situation. Optionally, please refer to [the relevant documentation]. Figures 1 to 3 In some embodiments, the second support 6 is a Y-shaped support.

[0063] Optionally, please refer to Figures 1 to 3 In some embodiments, the end of the device body 1 away from the pressing member 2 is provided with a first limiting surface 12 and a second limiting surface 13 that are perpendicular to each other. The first limiting surface 12 abuts against the side of the second bracket 6 near the pressing member 2, and the second limiting surface 13 abuts against the side of the second bracket 6 near the first bracket 5 in the interval direction of the two connecting rods 4.

[0064] Specifically, the second support 6 is located on the left rear side of the device body 1. The left rear end of the second support 6 is provided with a right-angle notch. The two right-angle surfaces of the right-angle notch form a first limiting surface 12 and a second limiting surface 13, respectively. The first limiting surface 12 is arranged facing rearward and abuts against the front side of the lower end of the second support 6. The second limiting surface 13 is arranged facing rightward and abuts against the left side of the lower end of the second support 6. In this way, the second support 6 is perpendicularly connected to the device body 1, so that a limiting is formed between the second support 6 and the device body 1, thereby preventing the second support 6 from rotating.

[0065] Optionally, please refer to Figures 1 to 3 In some embodiments, the second bracket 6 is movably and adjustable on the main body 1 of the device. Since the wind turbine wind vane zeroing device 100 supports and limits the pointing rod 410 of the mechanical wind vane 400 through the second bracket 6, the installation position of the second bracket 6 on the main body 1 can be adjusted by moving it up and down so that the wind turbine wind vane zeroing device 100 can be adapted to different mechanical wind vanes 400.

[0066] Further, please refer to Figures 1 to 3 In some embodiments, the second bracket 6 is fixed to the second limiting surface 13 by a screw connector 62. The second bracket 6 is provided with a through groove 63 through which the tail of the screw connector 62 passes, and the through groove 63 extends in the vertical direction.

[0067] Specifically, a through groove 63 is provided through the lower end of the second bracket 6, extending horizontally. The through groove 63 extends vertically. The screw connector 62 can be a bolt, etc. A threaded hole is provided on the second limiting surface 13 to engage with the screw connector 62. The tail of the screw connector 62 passes through the through groove 63 from right to left and is threaded into the threaded hole on the device body 1. The head of the screw connector 62 is located on the right side of the lower end of the second bracket 6. After loosening the screw connector 62, the installation position of the second bracket 6 on the device body 1 can be adjusted vertically. After adjusting the second bracket 6 vertically, tightening the screw connector 62 will achieve a fixed connection between the second bracket 6 and the device body 1.

[0068] The specific shape and style of the main body 1 can be set according to the actual situation. Optionally, please refer to Figures 1 to 3 In some embodiments, a groove 11 is provided on the surface of the device body 1 near the pressing member 2. The groove 11 extends through the device body 1 vertically, and the width of the groove 11 gradually narrows in the direction from the pressing member 2 to the device body 1. When the wind turbine wind direction indicator zeroing device 100 is installed on the mechanical wind direction indicator 400, the two opposite sidewalls of the groove 11 in the groove width direction abut against the mechanical wind direction indicator 400.

[0069] Specifically, a V-shaped groove 11 with its opening facing forward is provided on the front surface of the main body 1 of the device, and the groove 11 extends vertically through the main body 1 of the device. When the wind turbine wind direction indicator zeroing device 100 is installed on the mechanical wind direction indicator 400, the groove 11 and the main body 420 of the mechanical wind direction indicator 400 form a snap-fit ​​engagement, so that the wind turbine wind direction indicator zeroing device 100 can be well fixedly installed on the mechanical wind direction indicator 400.

[0070] Further, please refer to Figures 1 to 3 In some embodiments, the groove 11 has two slots 3 respectively on two opposite sidewalls in the groove width direction.

[0071] The pressing member 2 can move back and forth relative to the main body 1 along the connecting rod 4. For example, the front end of the connecting rod 4 passes through the pressing member 2 and is provided with a first wing nut 41. After the wind turbine wind direction indicator zeroing device 100 is fitted onto the wind direction indicator, the pressing member 2 is moved backward so that the pressing member 2 abuts against the front side of the wind direction indicator. Then, the first wing nut 41 on the connecting rod 4 is tightened, so that the wind turbine wind direction indicator zeroing device 100 can be fixedly installed on the wind direction indicator.

[0072] Optionally, please refer to Figures 1 to 3In some embodiments, the pressing member 2 is provided with through holes 23 and opening slots 24 at both ends of the two connecting rods 4 in the interval direction. Both the through holes 23 and the opening slots 24 penetrate the pressing member 2 in the extension direction of the connecting rods 4, so that the two connecting rods 4 pass through the pressing member 2 from the through holes 23 and the opening slots 24 respectively, with the opening slots 24 penetrating the pressing member 2 downward.

[0073] Specifically, the left and right ends of the pressure member 2 are respectively provided with through holes 23 and open slots 24. Both through holes 23 and open slots 24 penetrate the pressure member 2 from front to back upward. The front ends of the two connecting rods 4 pass forward through the pressure member 2 from the through holes 23 and open slots 24 respectively. The through holes 23 can be circular holes, and the open slots 24 extend vertically, with the lower end of the open slots 24 penetrating the pressure member 2 downward. In this way, the pressure member 2 can rotate about a connecting rod 4 that mates with the through hole 23, so that the wind vane can be installed between the two connecting rods 4. This facilitates the installation of the wind vane zeroing device 100 of the wind turbine unit and also prevents the pressure member 2 from falling off.

[0074] Optionally, please refer to Figures 1 to 3 In some embodiments, the pressing member 2 and the connecting rod 4 are detachably connected. The pressing member 2 has a first pressing surface 21 and a second pressing surface 22 opposite to each other in the extending direction of the connecting rod 4.
