AI Technical Summary

Technical Problem

Existing wind turbine vibration acquisition and transmission devices are easily interfered with when the wind turbine casing vibrates, leading to data acquisition errors. In particular, when the vibration sensor is directly installed inside the casing, the accuracy of the data is difficult to guarantee.

Method used

The design combines a vertical damping connection mechanism with a horizontal damping structure and a weighted design. Through vertical and horizontal damping buffering, the influence of wind turbine casing vibration on vibration sensors is eliminated. The weighted design ensures the stability of the sensor's center of gravity and reduces the impact of casing vibration on data acquisition.

Benefits of technology

By combining these technologies, the accuracy of the vibration transmission device for wind turbines has been improved, ensuring data accuracy and facilitating accurate assessment of the actual condition of the wind turbines by staff.

Abstract

The utility model discloses a high-precision wind turbine generator vibration acquisition and transmission device, which relates to the technical field of wind driven generators and comprises a vibration sensor arranged in a wind turbine generator casing, a wireless communication data acquisition and remote transmission device used for acquiring data of the vibration sensor and transmitting the data outwards, and a communication antenna used for transmitting the data, through the arrangement of the vertical damping connecting mechanism and the horizontal damping structure, the vibration of the wind turbine generator casing can be buffered and weakened, meanwhile, the center of the connecting cover can be moved downwards by the weight, so that the gravity center of the vibration sensor mounted on the fixing piece is moved downwards, the relatively stable effect is achieved, and the vibration sensor, the weight and the weight are matched with one another. Finally, the purpose of eliminating the influence of the wind turbine generator enclosure vibration on the vibration sensor is achieved, the situation that the vibration sensor is influenced by the wind turbine generator enclosure to generate vibration, and consequently data collection errors occur is avoided, and therefore the accuracy of the wind turbine generator vibration collection and transmission device is improved.
