Device for monitoring icing of power transmission lines and preventing tower from falling down

A device for monitoring icing of power transmission lines and preventing a tower from falling down, comprising a power transmission tower, an insulator string and a connecting mechanism arranged between the power transmission tower and the insulator string;

• the connecting mechanism comprises two connecting plates, a monitoring-control connector is arranged in series between the two connecting plates, and connecting grooves matched with two ends of the monitoring-control connector are respectively arranged on sides of the two connecting plates;
• the two ends of the monitoring-control connector are respectively inserted into the two connecting grooves, and the monitoring-control connector is provided with a monitoring component;
• the monitoring component is in signal connection with a master station of a system, the two ends of the monitoring-control connector are respectively provided with load release components, and the two ends of the monitoring-control connector are fixedly connected with the two connecting plates through the load release components;
• and sides of the two connecting plates far away from the monitoring-control connector are respectively fixed with the power transmission tower and one end of the insulator string, the other end of the insulator string is hung with wires and a damping component is arranged between the two connecting plates;
• the load release components comprise two bolts, top surfaces of the two ends of the monitoring-control connector respectively located in the connecting grooves are provided with connecting holes, top surfaces of the two connecting plates are provided with positioning holes, the positioning holes penetrate through the connecting grooves and correspond to the connecting holes, and the bolts are arranged in two groups of the respectively correspondingly arranged connecting holes and the positioning holes, and bolts are connected with inner walls of the connecting holes and the positioning holes through threads;
• two ends of a top surface of the monitoring-control connector are respectively provided with release holes, and the two release holes are respectively located between the connecting holes and end surfaces closest to the connecting holes, axial directions of the release holes are parallel to axial directions of the connecting holes, the release holes are strip-shaped, and directions of longest diameters of the release holes are parallel to a length direction of the monitoring-control connector;
• when an icing load reaches a preset load, the bolts connecting the connecting plates with the monitoring-control connector are subjected to punching failure, and the bolts slide along the release holes, and consequently tension of the wires is released and thus the load is released.
