Multi-vibration-mode control instrument for steel tube tower rod piece of power transmission line

The invention provides a power transmission line steel tube tower rod piece multi-vibration-mode control instrument, and belongs to the field of control instruments. The load problem of a large-span line high-voltage power transmission line power transmission tower and the multi-vibration type vortex-induced vibration problem of a steel tube tower rod piece under the complex wind environment condition are solved, a fixing device of the control instrument is used for fixing a steel tube, an acceleration sensor and a telescopic device are arranged in the fixing device, the acceleration sensor is used for measuring vibration signals of the steel tube, and the telescopic device is used for measuring the vibration signals of the steel tube. The acceleration sensor is electrically connected with the controller, the controller recognizes the vibration frequency of the steel pipe, the telescopic device comprises a first telescopic rod and a second telescopic rod which are electrically connected with the controller, t
