Abstract
The utility model discloses an anti-drop portable anti-thunder side rod for a high-voltage transmission line. The anti-drop portable anti-thunder side rod comprises a rod body and a rod head. The front end of the rod body is connected with the back end of the rod head. The rear section of the rod body is provided with a U-shaped locking and connecting device for installing the anti-thunder side rod. The rod body is a hollow tube. External diameter of the rod head is less than internal diameter of the rod body. The rod head can slide in the rod body. As the rod body is provided with the U-shaped locking and connecting device, stable installation of the anti-thunder side rod is guaranteed, and the anti-thunder side rod will not fall off and loosen after being installed. Thus, permanent power failure accident caused by the anti-thunder side rod which falls off and is hung on a transmission line is avoided. As a telescoping structure is arranged between the rod body and the rod head, the rod head can be placed in the rod body when the anti-thunder side rod is carried. Thus, length of the whole anti-thunder side rod is reduced by nearly half, and then the anti-thunder side rod is convenient to carry.
