A sound-based early warning device for offshore wind turbine bolts

Abstract

This utility model discloses an acoustic signature warning device for offshore wind turbine bolts, including an acoustic shielding cover. A bottom cover is snapped onto the bottom of the acoustic shielding cover, and a control box is fixed on the acoustic shielding cover below the bottom cover. By installing the acoustic shielding cover, this utility model optimizes the device's structure. During use, the user can cover the top of the offshore wind turbine mounting column with the acoustic shielding cover for installation. Then, the user opens the air valve installed on the pre-installed air pipe, inflating the explosion-proof airbag pressure plate through the pre-installed air pipe to firmly press down on the offshore wind turbine mounting column for fixation. This device improves the stability and shock absorption effect of the acoustic shielding cover during installation through the airbag's buffer-type compression structure. Furthermore, the acoustic shielding cover reduces noise interference and impact damage caused by direct impact from sea winds and heavy rain on the sensor structure, improving the accuracy and service life of acoustic signature monitoring.
