Description

Technical Field

[0001] This utility model belongs to the field of vibration monitoring technology, and in particular relates to an explosion-proof vibration monitoring device. Background Technology

[0002] Tall structures refer to structures with large height and small cross-section. These structures are very common in fields such as construction, petrochemicals, and wind power, such as tall buildings, observation towers, petrochemical towers, chimneys, and wind turbine towers. Due to their structural characteristics, these devices are easily affected by wind loads and vibrate. When the vibration is too large, it may lead to structural fatigue failure or even destruction. At the same time, due to the randomness of wind loads, the structural analysis results obtained by theoretical calculations or numerical simulations will differ significantly from the actual situation. Therefore, long-term vibration monitoring of such devices and safety assessment of the structure based on measured vibration data are of great significance.

[0003] A vibration monitoring device is an instrument used for high-precision monitoring of the vibration of critical equipment. It can be directly installed at locations on the main structure where significant vibration occurs; for tall structures, it is typically installed at the top. The device incorporates high-precision sensors to collect data such as vibration acceleration and tilt angle, and transmits this data to a terminal via IoT card technology. As the primary monitoring component, the vibration monitoring device needs to provide stable, long-term data monitoring and transmission. However, the tops of many tall structures often operate in harsh environments, making the device susceptible to damage or failure due to rain, strong winds, snow, lightning, and other natural environmental factors.
