Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vibration detection devices, specifically a vibration detection device for a fan drive chain. Background Technology
[0002] A wind turbine drivetrain vibration detection device is used to monitor the vibration status of a wind turbine drivetrain system. It is primarily used to monitor the vibration of the wind turbine drivetrain during operation in real time, including the vibration of key components such as the gearbox, drive shaft, and couplings. By collecting, analyzing, and processing vibration signals, potential faults in the drivetrain system can be detected promptly, such as gear wear, shaft imbalance, and bearing failure.
[0003] Existing technology publication CN221703895U discloses a wind turbine drive chain monitoring device, including a mounting box. A vibration sensor is fixedly installed on the inner wall of one side of the mounting box, and the vibration sensor is electrically connected to a data acquisition device. The data acquisition device is fixedly installed on the inner wall of the other side of the mounting box. Several stabilizing connection mechanisms are also provided on the top and bottom surfaces of the mounting box. After the mounting box is installed on important transmission parts such as bearings and gears in the wind turbine drive chain, the mechanical vibration generated when the wind turbine drive chain is running will be transmitted to the mounting box. The vibration sensor inside the mounting box will convert the energy generated by these vibrations into electrical signals and transmit them to the data acquisition device. The data acquisition device will upload the signals. By monitoring and analyzing abnormal vibration data and trends, personnel can understand the operating status of the wind turbine drive chain, thereby enabling early detection of drive chain failures, reducing the failure rate of the wind turbine unit, and lowering maintenance costs.
[0004] However, existing vibration detection devices for wind turbine transmission chains are typically installed on the wind turbine itself, and the wind turbine generates vibrations during operation. Since the vibration detection device is unlikely to buffer these vibrations, the vibrations cause external interference to the detection device, affecting its accuracy. Furthermore, the vibrations also cause mechanical impacts to the detection components, thus affecting the detection accuracy and service life of the device. Additionally, the detection components inside the device generate heat during the detection process, which is usually dissipated through heat vents. This method is ineffective in cooling the device, resulting in poor heat dissipation. Therefore, we propose a new vibration detection device for wind turbine transmission chains.

[0015] (III) Beneficial Effects
[0016] This utility model provides a vibration detection device for a fan drive chain, which has the following advantages:
[0017] (1) The vibration detection device of this type of fan transmission chain, through the setting of buffer ring, mounting screw and buffer spring, when the fan transmission chain vibration detection device is used, since the mounting screw is installed together with the equipment, the vibration will first act on the mounting screw. Due to the installation method, the two buffer springs will buffer the vibration of the mounting screw. At the same time, the vibration acts on the buffer ring. Since the buffer ring is made of rubber material, it has the function of deformation, which will buffer the vibration again, thereby minimizing the vibration acting on the detection device, reducing the impact of external interference on the accuracy and mechanical impact of the detection device, thus improving the detection accuracy and service life of the detection device.
[0018] (2) In this type of fan transmission chain vibration detection device, when the detection component inside the vibration detection device generates heat during the detection process, the cooling surface and heating surface of the semiconductor cooling chip heat up and cool down respectively, while the cooling fan draws the heat from the heating surface and discharges it through the mesh, and the cooling fan draws the cold air from the cooling surface and applies it to the component inside the detection body, thereby absorbing the heat and dissipating it through the heat dissipation mesh. Therefore, the heat dissipation effect of the vibration detection device is improved, and the component is prevented from being damaged due to overheating. Attached Figure Description

[0026] Furthermore, control buttons 5 and a display screen 6 are installed on the front of the control panel 4. Both control buttons 5 and the display screen 6 are electrically connected to the detection motherboard 102. The control buttons 5 facilitate operation by the staff, and the display screen 6 can display the detected vibration data.
[0027] Furthermore, a fixing plate 9 is fixedly connected to the outside of the vibration sensor 8. Fixing holes 10 are provided at the four corners of the front of the fixing plate 9. The vibration sensor 8 can be installed by placing the fixing plate 9 in the installation position and then inserting the bolts into the fixing holes 10 and tightening them.
[0028] Furthermore, a cooling fan 202 is installed on one side of the thermoelectric cooler 201. The cooling fan 202 is located inside the heat sink 2. The thermoelectric cooler 201 can cool and heat, and when the heating surface is hot, the cooling fan 202 will run to generate suction, thereby extracting and dissipating the heat.
[0029] Furthermore, the output terminals of the detection motherboard 102 are electrically connected to the signal processor 103, the data analyzer 104, and the communication module 105, respectively. The detection motherboard 102 is electrically connected to the data line 7. The vibration signal of the transmission chain is collected by the vibration sensor 8 and transmitted to the signal processor 103 through the data line 7. At this time, the signal processor 103 filters, amplifies, and digitizes the vibration signal, and then transmits it to the data analyzer 104. The data analyzer 104 analyzes the vibration data and extracts the vibration frequency, amplitude, spectrum, etc. The data is then displayed on the display screen 6 and transmitted to the monitoring system terminal through the communication module 105.
[0030] Furthermore, a heat dissipation mesh 101 is fixedly connected to the other side of the detection body 1. The heat dissipation mesh 101 and the partition mesh 3 are symmetrically arranged. The heat dissipation mesh 101 can quickly dissipate the heat inside the detection body 1.

[0032] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the fan drive chain vibration detection device, the operator positions the mounting plate 11 in the installation position and installs the buffer ring 12 into the through-hole on the mounting plate 11. Then, one of the buffer springs 14 is installed on the mounting screw 13, and the mounting screw 13 is passed through the through-hole of the buffer ring 12. At this time, the other buffer spring 14 is installed on the mounting screw 13, and then the mounting screw 13 is tightened to complete the installation. Then, the operator installs the vibration sensor 8 in the detection position. After installation, during the detection process, the vibration sensor 8 collects the vibration signal of the drive chain and transmits it to the signal processor 103 through the data cable 7. At this time, the signal processor 103 filters, amplifies, and digitizes the vibration signal, and then transmits it to the data analyzer 104. The data analyzer 104 analyzes the vibration data and extracts the vibration frequency, amplitude, spectrum, etc. The data will then be displayed on the display. On the display screen 6, data is transmitted to the monitoring system terminal via the communication module 105. At this time, the detection component inside the vibration detection device will generate heat. The cooling surface and heating surface of the semiconductor cooling chip 201 will heat and cool respectively. The heat dissipation fan 202 will draw the heat from the heating surface and discharge it through the mesh 3. The cooling fan 203 will draw the cold air from the cooling surface and apply it to the components inside the detection body 1, thereby absorbing the heat and dissipating it through the heat dissipation mesh 101. When the vibration of the fan acts on the detection device, since the mounting screw 13 is installed with the equipment, the vibration will first act on the mounting screw 13. Due to the installation method, the two buffer springs 14 will buffer the vibration of the mounting screw 13. At the same time, the vibration will act on the buffer ring 12. Since the buffer ring 12 is made of rubber material, it has the function of deformation and will buffer the vibration again, thereby minimizing the vibration acting on the detection device. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
