Abstract

The invention discloses a bolt monitoring system of a wind power generating set, which includes first and second sensors and a control system installed on the base of the bearing outer ring. Wherein, the first sensor points to the default installation position of the bolt, and the second sensor points to the exit position after the deformation of the bolt, and the control system judges the state of the bolt by analyzing the counts of the first and second sensors.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a bolt detection system and method for a wind power generating set. Background technique [0002] High-strength connecting bolts are the most common and key force-transmitting connecting parts of high-power wind turbines. They are often used between hubs and rotating shafts, pitch bearings, tower flanges and other major structural components. The high-strength connecting bolt bears the aerodynamic load transmitted from the blade, the gravity load and thermal load of the large component itself. These loads are transmitted to the main stress-bearing structures through high-strength connecting bolt groups, and at the same time, the bolts are subjected to combined loads of axial force, bending moment, lateral force and torque. Therefore, the stability of high-strength bolts is directly related to the safe operation of wind turbines and the safety of related operators. Once they b...
