[0029] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0030] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" are generally defined in relation to the drawing planes of the accompanying drawings, and "inner" and "outer" refer to the inside and outside of the relevant components. Furthermore, the terms "first" and "second" are used solely for purposes of distinction and are not to be construed as indicating or implying relative importance.

[0031] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0032] The wind vane is mainly used to detect the direction of the wind and can assist wind turbines in adjusting the direction of the wind rotor for better power generation.

[0033] The installation of wind vanes in related technologies usually adopts a simple mechanical fixing method, such as drilling a hole on the bracket and inserting the barrel of the wind vane into the hole to fix it. However, since the wind turbine generator set is in a high wind speed environment for a long time, the wind vane is always subjected to large wind impacts. After long-term use, the connection between the wind vane and the bracket is prone to loosening, and the wind vane is prone to tilting or deflecting, affecting the accuracy of the wind vane, and thus affecting the power generation efficiency of the wind turbine generator set. At the same time, the wind turbine generator set will also generate vibrations during operation. The wind vane is subject to long-term vibrations and is also prone to position changes, affecting the accuracy of wind direction detection. When the wind vane is tilted or deflected, maintenance personnel are required to regularly check and calibrate it, which is a large workload and high maintenance cost. For example, the patent publication number is CN116066294A, and the patent name is Wind Farm Integrated Power Control System, which discloses a method for installing and fixing the wind vane, which is prone to tilting or deflection.

[0034] For this reason, Figure 1-Figure 4 As shown, one aspect of the present disclosure provides a weather vane installation device, comprising a bracket 1, a limiting member 2 and a limiting collar 3;

[0035] The bracket 1 is used to be installed on the wind turbine, and the limiting collar 3 is used to be fixed on the cylinder of the wind vane 4. The limiting collar 3 and the cylinder of the wind vane 4 are coaxially arranged and both are vertically arranged. The limiting collar 3 has a first limiting portion 31 extending in the radial direction. The limiting member 2 is detachably connected to the bracket 1. The limiting member 2 is provided with a second limiting portion 21. The first limiting portion 31 and the second limiting portion 21 are connected to each other. The cooperation of the first limiting portion 31 and the second limiting portion 21 can limit the rotation and tilt of the wind vane 4 around the axis, so that the N point of the wind vane 4 points to the tail of the wind turbine, and the S point of the wind vane 4 points to the head of the wind turbine.

[0036] The inner diameter of the limiting collar 3 is slightly larger than the barrel of the wind vane 4, allowing the limiting collar 3 to fit over the barrel of the wind vane 4. The wind vane 4 comprises a barrel and a rotatable body. The body is connected to the top of the barrel and can rotate in response to wind force, enabling wind direction detection. The limiting collar 3 fits over the barrel without affecting the body's rotation. The body may include a wind direction arrow, a tail, and a rotation axis. The wind direction arrow and tail are interconnected and connected to the rotation axis, which is connected to the barrel, allowing the wind direction arrow and tail to rotate.

[0037] In the above technical solution, by connecting the limiting collar 3 with the cylinder of the wind vane 4, and then by cooperating with the first limiting portion 31 and the second limiting portion 21 on the limiting member 2, the limiting collar 3 and the limiting member 2 interact with each other, thereby limiting the cylinder of the wind vane 4, thereby improving the installation stability of the wind vane 4, and preventing the wind vane 4 from rotating or tilting after being loosened due to long-term wind force, so that the N point of the wind vane 4 can continue to point to the tail of the wind turbine, and the S point of the wind vane 4 can continue to point to the head of the wind turbine, which can ensure the detection accuracy of the wind vane 4 and thus ensure the power generation efficiency of the wind turbine generator set. This wind vane installation device can ensure the stability of the wind vane 4, reduce the need for frequent calibration and maintenance, and thus greatly reduce the workload and operating costs of maintenance personnel, which is of great significance, especially in remote or offshore wind farms. In addition, the limiting member 2 is connected to the bracket 1, which can realize the installation and fixation of the wind vane 4, so that the wind vane 4 is fixed to the wind turbine.

[0038] The limiting collar 3 can be welded and fixed on the cylinder of the wind vane 4, so that the limiting collar 3 and the cylinder of the wind vane 4 are connected as one.

[0039] Optionally, in one embodiment of the present disclosure, there are two first limiting portions 31 disposed around the axis of the limiting collar 3, with the line connecting the two first limiting portions 31 intersecting the axis of the limiting collar 3. There are two second limiting portions 21, with the first limiting portions 31 corresponding one to the second limiting portions 21. This arrangement creates a balanced limiting effect, thereby further improving the installation stability of the wind vane 4.

[0040] Among them, a first limiting portion 31 cooperates with a second limiting portion 21, and another first limiting portion 31 cooperates with another second limiting portion 21. The line connecting the two first limiting portions 31 intersects with the axis of the limiting collar 3, so that the two first limiting portions 31 can be symmetrically distributed around the axis of the limiting collar 3, thereby producing a balanced limiting effect.

[0041] Optionally, in another embodiment of the present disclosure, the number of first limiting portions 31 may be greater than two, and they are arranged around the axis of the limiting collar 3. Multiple first limiting portions 31 may be grouped in pairs and symmetrically arranged around the axis of the limiting collar 3. The number of second limiting portions 21 may be greater than two, and the first limiting portions 31 correspond one-to-one to the second limiting portions 21.

[0042] Optionally, in one embodiment of the present disclosure, one of the first limiting portion 31 and the second limiting portion 21 is configured as a groove, and the other is configured as a protrusion, which is capable of snapping into the groove. This configuration facilitates the cooperation between the first limiting portion 31 and the second limiting portion 21 to achieve a limiting effect. It should be noted that the specific configuration of the first limiting portion 31 and the second limiting portion 21 as a protrusion and a groove can be determined based on actual needs.

[0043] The convex portion can be inserted into the groove, and the sidewall of the convex portion can contact the groove wall of the groove. In some examples, the surface of the convex portion can be covered with a rubber layer, and the rubber layer contacts the groove wall of the groove to improve the contact effect, so that the first limiting portion 31 and the second limiting portion 21 can be firmly connected.

[0044] Optionally, in one embodiment of the present disclosure, the limiting member 2 is configured as a limiting sleeve, which is sleeved over the body of the wind vane 4 and the limiting collar 3. The limiting sleeve and the limiting collar 3 are coaxially arranged, and the second limiting portion 21 is arranged on the inner wall of the limiting sleeve. This arrangement can cover the body of the wind vane 4, protecting the body of the wind vane 4 while providing a limiting effect, while also ensuring the stability of the limiting effect.

[0045] The inner diameter of the limiting sleeve is larger than the outer diameter of the body of the wind vane 4 and the limiting collar 3, so that the body of the wind vane 4 and the limiting collar 3 can be directly inserted into the limiting sleeve. It is understood that during assembly, after the limiting collar 3 is fixed to the body of the wind vane 4, the wind vane 4 and the limiting collar 3 are placed together into the limiting sleeve, so that the first limiting portion 31 and the second limiting portion 21 are connected, thereby generating a limiting effect.

[0046] In some examples, in the vertical direction, the length of the limiting sleeve is consistent with the length of the cylinder of the wind vane 4, so that the cylinder of the wind vane 4 is arranged in the limiting sleeve.

[0047] Optionally, in one embodiment of the present disclosure, the second limiting portion 21 is configured as a groove formed on the inner wall of the limiting sleeve, the groove extending in the vertical direction, the upper end of the groove being open in the vertical direction for the first limiting portion 31 to be engaged, and the first limiting portion 31 being configured as a protrusion formed on the outer wall of the limiting collar 3. This configuration facilitates the engagement of the limiting collar 3 into the limiting sleeve and the engagement of the first limiting portion 31 into the groove.

[0048] It can be understood that when the cylinder of the wind vane 4 needs to be placed in the limiting sleeve, when the cylinder of the wind vane 4 and the limiting ring 3 are inserted into the limiting sleeve together, the first limiting part 31 can be directly inserted into the groove to realize the connection between the two, thereby generating a limit.

[0049] In some examples, the groove is formed by an inward depression of the inner wall of the limiting sleeve, whereby the groove directly passes vertically upward through the top of the limiting sleeve, forming an open structure for the first limiting portion 31 to be engaged with. In other examples, the inner wall of the limiting sleeve forms two opposing protrusions with a space between the two protrusions, and the space is configured as a groove.

[0050] Optionally, in another embodiment of the present disclosure, the limiting member 2 is constructed as a column, which is located on the side of the cylinder of the wind vane 4. The column is provided with a groove concave in the radial direction, and the groove cooperates with the convex portion to achieve limiting.

[0051] Optionally, in one embodiment of the present disclosure, the bracket 1 includes a base frame 11 and a connecting portion 12. The base frame 11 is connected to the wind turbine, the connecting portion 12 is connected to the base frame 11, and the limiter 2 is detachably connected to the connecting portion 12. The base frame 11 is provided to facilitate connection with the wind turbine, and the connecting portion 12 can provide support for the wind vane 4.

[0052] The connecting portion 12 can be integrally formed with the base frame 11 , and the bottom of the limiting member 2 is connected to the top of the connecting portion 12 , thereby producing a fixing effect and fixing the wind vane 4 at the same time.

[0053] Optionally, in one embodiment of the present disclosure, a first flange 22 is provided at the bottom of the position-limiting member 2, and a second flange 13 is provided at the top of the connecting portion 12. The first flange 22 and the second flange 13 are detachably connected by bolts. This arrangement facilitates connection and removal of the position-limiting member 2 from the connecting portion 12, and the cooperation between the first flange 22 and the second flange 13 improves the secure installation of the wind vane 4.

[0054] Optionally, in one embodiment of the present disclosure, the connecting portion 12 is configured as a cylinder, which is coaxially arranged with the stopper 2. The cylinder is used for allowing the line to pass through and connect to the wind vane 4. This arrangement facilitates the connection between the line and the wind vane 4, avoids exposing the line, and protects the line. The line is connected to the wind vane 4 and the fan.

[0055] It can be understood that the bottom of the limiting sleeve is connected to the top of the cylinder. After the wind vane 4 is set in the limiting sleeve, the line passes through the cylinder and enters the limiting sleeve to connect with the bottom of the wind vane 4.

[0056] Optionally, in one embodiment of the present disclosure, the base frame 11 includes a plurality of hollow columns 14, which are interconnected. One of the columns 14 has a through hole connected to the connecting portion 12. The connecting portion 12 communicates with the through hole to allow the wiring connected to the wind vane 4 to pass through. This arrangement allows the wiring to be hidden within the columns 14, thereby protecting the wiring.

[0057] It is understandable that the circuit connected to the wind vane 4 can be passed through the limiting sleeve into the connecting portion 12 and then passed through a column 14 through the through hole to protect the circuit.

[0058] In some examples, multiple columns 14 can be placed horizontally or vertically, and can be connected to each other to form a whole base frame 11 to achieve connection with the fan, and can be specifically arranged according to needs.

[0059] A second aspect of the present disclosure further provides a wind turbine generator set, comprising a wind turbine, a wind vane 4 and the above-mentioned wind vane mounting device.

[0060] The bracket 1 of the wind vane mounting device is connected to the wind turbine, and the limiting collar 3 of the wind vane mounting device is fixedly sleeved on the cylinder of the wind vane 4 .

[0061] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0063] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
