Description

Technical Field

[0001] This utility model relates to the field of wind power technology, and in particular to a mounting bracket for a temperature and humidity sensor of a wind turbine. Background Technology

[0002] Wind power modules, as an important component of clean energy systems, have significant advantages such as being green and renewable, and having zero carbon emissions. They mainly consist of a wind turbine, main shaft, gearbox, generator, and control system.

[0003] In wind turbine modules, the gearbox is a high-load operating component that generates a significant amount of heat during prolonged operation. Simultaneously, humidity fluctuations are common inside the gearbox. Excessive temperature and humidity can accelerate lubricant aging, component corrosion, or insulation failure. Therefore, temperature and humidity sensors are necessary to monitor environmental conditions in real time and ensure safe equipment operation. However, existing temperature and humidity sensors often require control via microcontrollers such as STM32 for data recording and remote transmission. The sensor circuit boards are typically soldered to the inner wall of the gearbox, making internal structure maintenance difficult and hindering disassembly for component maintenance. Furthermore, the significant differences in gearbox structures between different motors result in poor circuit board compatibility, cumbersome installation, and hinders rapid deployment and modular maintenance.

[0006] As a further improvement of this utility model, displacement grooves are provided on both sides of the chassis, the displacement grooves are horizontally placed on the inner wall of the chassis, and displacement blocks that match the displacement grooves are fixedly provided on the outer side of the side plates.

[0007] As a further improvement of this utility model, a screw hole is provided on one side of the side plate, and an assembly bolt is connected to the screw hole by an internal thread. Multiple screw holes for fastening the assembly bolts are also provided on the inner walls of both sides of the chassis.

[0008] As a further improvement of this utility model, a sliding connecting plate is fixedly provided on the center side of the assembly support rod. The sliding connecting plate has a T-shaped plate structure, and one end of the sliding connecting plate is slidably connected to the slot.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 As shown, a mounting bracket for a temperature and humidity sensor of a wind turbine includes a housing 1, inside which a motor sub-box 2 is disposed. A displacement frame 3 is slidably connected between the inner walls of the housing 1 and the motor sub-box 2. The displacement frame 3 is slidably disposed between the opening of the housing 1 and the motor sub-box 2. The displacement frame 3 includes a central rod 301, and side plates 302 are fixedly disposed on both sides of the central rod 301. The central rod 301 has a slot 6, and a pair of mounting support rods 4 with mounting sleeves 5 are slidably connected to the central rod 301. The two mounting sleeves 5 are respectively fixedly disposed at the top and bottom ends of the mounting support rods 4, and the mounting sleeves 5 have through holes for inserting a circuit board backplate. The circuit board is an integrated circuit board, and four corners on one side are fixed with plug-in posts that match the mounting sleeves 5. The circuit board is preferably a breadboard, which embeds an STM32f103 microcontroller powered by a battery, and the STM32f103 microcontroller is also electrically connected to an RS485 temperature and humidity sensor.

[0021] In addition, to ensure the reliability of the movement and limiting of the displacement frame 3, see attached... Figure 3 , 4 As shown, displacement grooves 7 are provided on both sides of the chassis 1. The displacement grooves 7 are horizontally placed on the inner wall of the chassis 1. Displacement blocks 8 that match the displacement grooves 7 are fixedly installed on the outer side of the side plates 302; providing guidance for the movement of the displacement frame 3 on the inner wall of the chassis 1. A screw hole is provided on one side of the side plate 302, and an assembly bolt 9 is threaded into the screw hole. Multiple screw holes for tightening the assembly bolts 9 are also provided on the inner walls of both sides of the chassis 1; ensuring that the displacement frame 3 is reliably fixed between the chassis 1.

[0022] As attached Figure 3 ,4 As shown, a sliding connecting plate 10 is fixedly installed on the center side of the assembly support rod 4. The sliding connecting plate 10 has a T-shaped plate structure, and one end of the sliding connecting plate 10 is slidably connected to the slot 6; it provides guidance for the sliding of the assembly support rod 4 in the slot 6. Both sides of the sliding connecting plate 10 are threadedly connected with combination bolts 11, and several screw holes are evenly spaced on the top and bottom sides of the slot 6; this ensures reliable positioning of the assembly support rod 4. The spacing between the two assembly support rods 4 is adjustable to accommodate circuit boards with different spacing widths.

[0023] Working Principle: In practical implementation, when installing or maintaining a circuit board, the operator can slide the displacement frame 3 laterally within the displacement groove 7 on the inner wall of the housing 1. The displacement block 8, located on the outer side of the side plate 302, provides guidance and limitation, ensuring the displacement frame 3 can smoothly slide out from the outer area of ​​the motor sub-box 2. This facilitates subsequent maintenance of the motor sub-box 2 and its internal components. The through-hole of the mounting sleeve 5 on the mounting support rod 4 is used to insert an integrated circuit board. This circuit board can be connected to a battery for power and can achieve temperature and humidity signal acquisition and remote data transmission. To accommodate circuit boards of different sizes, the distance between the two mounting support rods 4 is adjustable. Their position on the central rod body 301 is adjusted by the sliding connecting plate 10 and the slot 6, and fixed by the combination bolts 11 and corresponding screw holes. After assembly, the operator can fix the entire displacement frame 3 to the screw hole position on the inner wall of the housing 1 using the assembly bolts 9 to achieve stable encapsulation of the overall sensor mounting structure; when replacement or maintenance is required, simply remove the assembly bolts 9 to pull out the entire displacement frame 3 for maintenance of the internal components of the motor sub-box 2.
