<P>PROBLEM TO BE SOLVED: To provide a device for preventing approach to a power line capable of easily opening/closing an approach prevention body such as an approach prevention bar without using a tool, and surely preventing misrecognition of a cable. <P>SOLUTION: A device for preventing approach to a power line comprises: an approach prevention body 2 rotatably arranged on a steel tower T side for preventing a movement to a power line E side; a rotation regulating mechanism 3 arranged on the steel tower T side capable of engaging with the approach prevention body 2 in a rotating direction; an opening/closing operation mechanism 4 arranged on the steel tower T side having an attachment part 41 capable of being fitted to a specific tablet P which an operator carries along, and having a press button 42 driven by the tablet P attached to the attachment part 41; and a power transmission mechanism 5, whose one side is connected to the rotation regulating mechanism 3 and the other side is connected to the opening/closing operation mechanism 4, for transmitting a pressing force of the press button 42 to the rotation regulating mechanism 3. When the press button 42 is in a pressed state, a rotation of the approach prevention body 2 is allowed by the rotation regulating mechanism 3, while the rotation of the approach prevention body 2 is regulated by the rotation regulating mechanism 3 when the tablet P is in a removed state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
