Abnormal bolt detection device for wind generating set

The invention provides an abnormal bolt detection device for a wind generating set, which relates to the technical field of bolt detection of wind generating equipment and comprises a blade bolt, a mounting assembly, a first detection mechanism and a second detection mechanism, an installation assembly is fixedly arranged outside a blade bolt of the wind generating set, a first detection mechanism is arranged on the top of the installation assembly, a plurality of second detection mechanisms are fixedly arranged on the periphery of the bottom of the installation assembly, and an abnormity alarm assembly and a control assembly are arranged on the top of the installation assembly. The sensing end of the bolt detection proximity switch is aligned with the upper end face of the outer bolt, when the bolt changes abnormally, the proximity switch gives an alarm and sends abnormal information to the main control system, the device can find out abnormal hidden dangers of the bolt in time, accidents are avoided, and de
