[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0035] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used in the present application are only for the purpose of describing the specific embodiments of the present application and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion. The terms "first", "second" and the like in the specification and claims of the present application or the above description of drawings are used to distinguish different objects, and are not intended to describe a particular order or primary and secondary relationship.

[0036] In the present application, the term "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive or alternative to other embodiments.

[0037] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection", "attach" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In the present application, the term "and / or" is only a description of the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the front and rear associated objects.

[0039] In the embodiments of the present application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length and width of various components in the embodiments of the present application shown in the drawings, and the overall thickness, length and width of the integrated device are only exemplary and should not constitute any limitation on the present application.

[0040] In this application, "multiple" means two or more (including two).

[0041] This application provides a fixing device for wind turbine measuring equipment, used for the fixed installation of wind turbine measuring equipment. The fixing device in this application includes, but is not limited to, speed sensors, acceleration sensors, displacement sensors, torque sensors, bending moment sensors, stress sensors, etc., and can also be a single physical module including one or more sensors to provide more directional detection angles or more detection types, or it can be an integrated physical module. Based on the above, the fixing device in this application can also be used to fix alarm equipment, control equipment, etc.

[0042] As an example, the wind turbine measurement equipment can be a torque sensor. By selecting core measurement points on the drive shaft, the torque sensor monitors the torque changes at each core monitoring point, thereby obtaining the operating rules of the wind turbine's main drive chain system under actual working conditions. This provides data support for the stable operation of wind turbines throughout their entire life cycle, including the research and development stage and actual production.

[0043] The aforementioned torque sensor can be either wired or wireless. Wired torque sensors typically employ a method of fixing the sensor to the drive shaft being measured for torque detection, thereby reducing detection errors caused by distance and improving detection accuracy. Wireless torque sensors typically use a non-contact detection method, employing brackets or other devices for installation and fixation, ensuring stable installation, reducing installation errors and detection errors caused by vibration, and ultimately ensuring detection accuracy. Therefore, this application is mainly applicable to the fixing of detection equipment such as wireless torque sensors and wireless torque acquisition instruments.

[0044] In the installation phase before measurement, the installation position of the fixing device is usually set according to the position of the drive shaft to be measured. The measuring equipment can be placed upright, tilted, or suspended. Its detection path can be upward, downward, oblique, or horizontal. It is necessary to ensure that the measuring equipment and the drive shaft do not contact each other and leave an appropriate distance.

[0045] Because wind turbine models differ, and the drive shafts of wind turbines vary in size, the position of the mounting device used to fix the measuring equipment must be adjusted to maintain an appropriate testing distance. However, traditional brackets are mostly only suitable for installing measuring equipment on the drive shafts of a single type of wind turbine, and cannot be applied to multiple or even all types of wind turbines, resulting in poor versatility and high testing costs.

[0046] In view of this, the wind turbine measurement device fixing device provided in the embodiments of the present application can better match different wind turbines and improve the versatility by arranging multiple adjustment positions on the connecting member of the tool body along at least the first direction and arranging a connecting part connected with the adjustment positions on the support frame to adjust the distance between the detection installation position and the transmission shaft.

The connecting corner position of the first support 121 and the second support 122 is fixedly connected with the reinforcing bracket 124, so as to increase the connecting strength of the first support 121 and the second support 122 and prevent deformation under stress.

[0059] As an example, the connecting part 1201 can include a connecting plate, opposite sides of the connecting plate along the third direction Z are provided with the adjusting position 113, the connecting plate is fixedly connected to the second end of the first support 121, and the connecting plate is connected to the adjusting position 113 of the tool body 11 to adjust the adjusting requirement of the support position.

[0060] The adjusting position 113 is provided with at least one adjusting hole 113a, and the connecting part 1201 is fastened and connected with the adjusting hole 113a through a fastener. Figure 2 As shown, the adjusting hole 113a at the adjusting position 113 is four and is circumferentially distributed. Correspondingly, four connecting holes are distributed on the connecting plate, each connecting hole is one-to-one corresponding with each adjusting hole 113a and is connected by using a locking part.

[0061] Regarding the connecting mode of the connecting part 1201 and the adjusting hole 113a, in another embodiment, the connecting part 1201 is provided with a plug-in part, the connecting part 1201 is plugged with the adjusting hole 113a through the plug-in part and is fixedly connected by using a locking part. In another embodiment, the connecting part 1201 is provided with a plug-in part, the plug-in part is a magnetic plug-in part, and the connecting part 1201 is fixedly connected with the adjusting hole 113a through the magnetic plug-in part.

[0065] As shown in Figure 2 , a side view of the wind turbine generator measurement equipment fixing device provided by some embodiments of the present application is shown. Figure 2

[0066] In a specific embodiment, the support frames 12 are two, and the two support frames 12 are symmetrically arranged along the third direction Z and connected to the same adjustment position 113. For example, as shown in Figure 2 , each connecting hole on the connecting part 1201 of the support frame 12 corresponds to each adjustment hole 113a on the same adjustment position 113 on the connecting plate, and each connecting hole is coaxially arranged with each adjustment hole 113a and locked in each adjustment hole 113a by a locking member, so as to realize the connection of the support frame 12 and the connecting member 112.

This structure realizes independent fixing for each support frame 12 and makes the locking more firm and reliable.

[0069] In order to improve the firmness and convenience of the connection between the support frame 12 and the nacelle, a magnetic member 123 can be arranged on the support frame 12. Optionally, the magnetic member 123 is arranged at the bottom of the support frame 12 and can be fixed on the support frame 12 by a locking member. Since the wind turbine nacelle has magnetism, the support frame 12 is fixed on the wind turbine nacelle by magnetic attraction, and the two are magnetically connected.

[0070] For example, during installation, appropriate height can be selected according to the diameter of the transmission shaft, and the two support frames 12 are fixed on the middle support plate by bolts. Then, the two support frames 12 are placed on the wind turbine nacelle platform, and the lower part of the nacelle platform is fixed by the magnetic member 123 corresponding to the foot position of the support frame 12 to prevent the support frame 12 from deviating. After the overall support frame 12 is fixed, the measurement equipment is fixed on the mounting table 111 by bolts to complete the overall installation of the fixing device 1.

[0071] It should be noted that the structure, number and connection method of the support frame 12 can be various, as long as the support and fixing functions are realized, which are not limited in this article. ​​

When installing the support frame 12, the support frame 12 is roughly matched with the matching surface of the nacelle platform through the positioning surface 122a, and then the support frame 12 is firmly fixed on the nacelle platform by the magnetic force, which can effectively prevent the overall fixing device 1 from shaking and improve the stability. The positioning and installation method can make the connection more accurate and fast, and the connection is more firm. In addition, the magnetic connection between the tool body 11 and the support frame 12 is easy to install and disassemble, which can significantly improve the disassembly efficiency.
