The utility model provides a wind
turbine bolt monitoring device based on an enamelled wire, the bolt head of each bolt is fixedly provided with two hangers, the enamelled wire passes through the two hangers on the bolt head and is fixedly connected with the two hangers, and the enamelled wire connects all bolts on the same
flange in series and then is connected to an on-off
data monitoring acquisition unit. The on-off
data monitoring and collecting unit is connected with the upper computer, when the bolt is loosened, the bolt head drives the enameled wire on the hanging lug to rotate synchronously, the enameled wire is stretched and fractured, and the on-off
data monitoring and collecting unit monitors a conduction
signal of the enameled wire and transmits the conduction
signal to the upper computer. According to the device, all bolt heads on the same
flange are connected in series through the varnished wires, and the conduction signals of the varnished wires are monitored, so that monitoring and early warning are carried out on the loosening and even
fracture risk of the bolts, effective monitoring of the bolts is realized, the loosening or
fracture problem of all the bolts on the same
flange can be monitored at a time, and the cost is low.
