[0021] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] It should be noted that in this embodiment, the orientation or positional relationship indicated by "bottom", "top", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of facilitating the description of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0024] It should also be noted that, in this embodiment, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] See Figure 1 and Figure 2 A proximity switch adjustment ruler for a wind turbine generator set includes three arms connected to form a Y-shaped structure. The included angle between any two adjacent arms is 120°. The lengths of the three arms are carefully designed to suit actual application scenarios. Each arm has three segments, from the outside to the inside: minimum thickness segment 1, transition segment 2, and maximum thickness segment 3. When in use, the distance between the measurement positions cannot be less than the minimum thickness, and the maximum distance cannot be greater than the maximum thickness.

[0026] The three arms are made of aluminum alloy, ensuring the ruler is lightweight and durable, not easily deformed, and can be used stably in the complex environment of wind turbine generators. Each of the three arms is engraved with markings and scales using laser engraving technology, which is clear, wear-resistant, and not easily worn down over long-term use, ensuring the accuracy and readability of the scales. The arm marked "Pitch 2-2.4 (mm)" is used for debugging the pitch position proximity switch, the arm marked "Generator 2-3 (mm)" is used for debugging the generator speed detection proximity switch, and the arm marked "Yaw 3-4 (mm)" is used for debugging the yaw position proximity switch.

[0027] All three arms have the same width, 8mm. Their lengths are also identical, consisting of a minimum thickness section (10mm), a transition section (linearly changing, 20mm), and a maximum thickness section (15mm). The thickness of each section is set according to the technical standards of the application location to accommodate the debugging requirements of proximity switches in different positions. Specifically, the arm marked "Pitch 2-2.4 (mm)" has minimum thickness section 1, transition section 2, and maximum thickness section 3 thicknesses of 2mm, 2-2.4mm, and 2.4mm respectively, and its length and scale range meet the debugging accuracy requirements of the pitch system. The arm marked "Generator 2-3 (mm)" has minimum thickness section 1, transition section 2, and maximum thickness section 3 thicknesses of 2mm, 2-3mm, and 3mm respectively, and the scale accuracy of this arm ensures the accuracy of the generator speed measurement unit. The arm marked "Yaw 3-4 (mm)" has minimum thickness section 1, transition section 2, and maximum thickness section 3 thicknesses of 3mm, 3-4mm, and 4mm respectively, and its scale and markings are also customized according to the characteristics of the yaw system.

[0028] When debugging the yaw position proximity switch, place the debugging ruler near the yaw system of the wind turbine generator. Position the arm marked "Yaw 2-2.4 (mm)" close to the proximity switch and yaw components. Place the arm marked "Yaw 3-4 (mm)" between the proximity switch and the yaw tooth peak. Adjust the position of the proximity switch according to the scale and markings, ensuring the distance is within the marked range to achieve the optimal detection distance. This ensures the proximity switch triggers a signal when the yaw tooth peak passes. Simultaneously, use relevant testing equipment (such as an oscilloscope) to monitor the output signal of the proximity switch until the signal reaches its optimal state, indicating that the yaw position proximity switch debugging is complete.

[0029] For debugging the pitch position proximity switch, in the pitch system of the wind turbine generator, align the arm marked "Pitch 2-2.4 (mm)" with the proximity switch and the pitch component. Finely adjust the position of the proximity switch according to the scale indication to ensure that the distance between the proximity switch and the pitch component is within the range of 2-2.4 (mm) (the specific unit is determined according to the actual design). Verify the debugging effect through the pitch system test procedure to ensure the accuracy of pitch position detection. When the outer ring stop of the pitch system rotates through, precisely adjust the position of the proximity switch to the marked range. The proximity switch accurately identifies the position information, ensuring the accuracy of pitch position detection.

[0030] When debugging the generator speed measuring proximity switch, place the debugging ruler near the generator speed measuring proximity switch and use the arm marked "Generator 2-3 (mm)" to measure the distance between the proximity switch and the generator speed dial. Adjust the position of the proximity switch base so that the distance between the speed measuring proximity switch and the generator speed measuring dial is within the range of 2-3 (mm) to ensure that the speed measuring unit can accurately detect changes in generator speed. Confirm the debugging results through feedback information from the generator control system to ensure the accuracy of generator speed measurement.

[0031] It is worth noting that the present invention uses a Y-shaped structure composed of three arms, which are arranged from the outside to the inside as the minimum thickness section, the transition section, and the maximum thickness section, respectively. The three arms are used for debugging the yaw position proximity switch, the pitch position proximity switch, and the generator speed detection proximity switch, which greatly improves the accuracy of the detection of each position of the wind turbine generator set, thereby improving the operational stability and reliability of the entire unit.

[0032] Secondly, a single adjustment ruler can be used simultaneously to adjust the yaw position, pitch position, and proximity switch of the generator speed measurement unit within the wind turbine generator set, eliminating the need for multiple tools and reducing tool costs and management difficulty.

[0033] In addition, the Y-shaped design and clear scale markings enable debugging personnel to operate quickly and intuitively, reducing debugging time and workload and improving work efficiency.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
