Description

Technical Field

[0001] This utility model relates to the field of infrared temperature measurement angle adjustment technology, specifically an infrared temperature measurement device for wind turbine brake discs with angle adjustment. Background Technology

[0002] During the operation of wind turbine units, the brake disc is the core braking component. When the brake pads and disc surface are subjected to intense friction during high-speed rotation braking, a large amount of heat is generated. Moreover, the heat is distributed very unevenly on the surface of the brake disc. The temperature in the friction contact area rises sharply, while the temperature in the non-contact area is relatively low. If this local overheating phenomenon is not monitored in time, it can easily lead to the degradation of the brake disc material performance, a decrease in braking efficiency, and even serious safety hazards such as cracks and deformation.

[0003] Infrared temperature measurement devices are mostly fixed installations, making it difficult to adapt to the rotation characteristics of brake discs. They can only monitor local areas and cannot cover the entire disc surface. Furthermore, they lack stable isolation from the high-speed rotating spindle, making them susceptible to vibration and causing temperature measurement deviations. Utility Model Content

[0036] The placement cylinder 4201 is located on the back of the fixing plate 421. The infrared thermal imager 5 is inserted into the placement cylinder 4201. The clamping ring 4202 is located on the top of the placement cylinder 4201 and on both sides of the surface of the infrared thermal imager 5.

The infrared thermal imager 5 can also detect different positions around the wind turbine brake disc 3.

[0038] Example 2

[0039] See Figure 1-8Furthermore, based on Embodiment 1, the fixing mechanism 2 further includes a mounting block 23, which is fixedly connected to the front and rear surfaces of the clamping ring 4202. A limiting groove 22 is opened inside the mounting block 23, and the front and rear sides of the limiting groove 22 are set as openings. A limiting plate 24 is inserted into the front and rear limiting grooves 22, and a screw 21 is threadedly connected to the limiting plate 24 and the mounting block 23.

[0040] Furthermore, the limiting plate 24 is inserted into the limiting groove 22, and the limiting plate 24 and the mounting block 23 are threadedly fixed by the screw 21, so that the clamping ring 4202 can clamp and fix the infrared thermal imager 5, which makes it convenient for the infrared thermal imager 5 to monitor the uneven heat generated by friction when the wind turbine brake disc 3 is rotating at high speed.

[0041] The infrared thermal imager draws inspiration from the existing FOTRIC348+ high-performance handheld infrared thermal imager: equipped with a 640×480 high-resolution infrared detector, it measures temperatures from -20℃ to +1550℃, with a thermal sensitivity as low as 0.03℃, making it suitable for detecting minute temperature differences. A single thermal image contains 307,200 temperature measurement points. The device supports 20-point, 10-line, and 20-area temperature measurement analysis. Combined with professional thermal imaging software, it can acquire a complete temperature data matrix, accurately determining the temperature of each point on the brake disc.

[0042] In actual operation, when this device is used, the infrared thermal imager 5 is inserted into the placement cylinder 4201, which pushes the connecting block 422 to drive the T-shaped block 429 to slide in the T-shaped groove 427 until the connecting block 422 drives the fixing block 4203. The fixing block 4203 drives the clamping ring 4202 to clamp and fix the infrared thermal imager 5. The limiting plate 24 is then inserted into the limiting groove 22, and the limiting plate 24 and the mounting block 23 are threaded and fixed by the screw 21. This allows the clamping ring 4202 to clamp and fix the infrared thermal imager 5, which is convenient for the infrared thermal imager 5 to monitor the uneven heat generated by friction when the wind turbine brake disc 3 is rotating at high speed. In addition, the infrared thermal imager 5 is electrically connected to an external display screen, which is convenient for the operator to view the values ​​on the display screen.

[0043] The arc-shaped ring 4106 drives the long block 4105 to be inserted into the long groove 4107 again, and the long plate 4102 drives the insert plate 4103 to be inserted into the slot 4104. The rotating plate 419 is rotated on the surface of the fixed rod 416 until the rotating plate 419 is inserted into the rectangular groove 4101. The screw 417 is used to fix it in place. The infrared thermal imager 5 can be fixedly set on the front of the wind turbine brake disc 3. When the wind turbine brake disc 3 rotates, the main shaft 1 rotates. The T-shaped annular slip ring 412 can also slide in the T-shaped annular slip groove 414 at the same time, which makes it convenient for the infrared thermal imager 5 to monitor the four sides of the wind turbine brake disc 3.

[0044] When the electric push rod 4205 is running, it drives the moving plate 424 to move within the square groove 4204. At the same time, the slider 423 can also slide within the groove 426, which makes it convenient for the infrared thermal imager 5 to detect different positions around the wind turbine brake disc 3.
