Abstract

A device for removing ice and snow from a power transmission line includes a support member installed on the power transmission line, and a vibrator that is provided for the support member and applies vibrations to the power transmission line so as to remove the ice and the snow attached to the power transmission line.

Claims

1. A device for removing ice and snow from a power transmission line, comprising:

a support member installed on the power transmission line; and

a vibrator that is provided for the support member and applies vibrations to the power transmission line so as to remove the ice and the snow attached to the power transmission line,

wherein;

the vibrator has a pair of vibrators that are symmetrically formed in a pair in a lengthwise direction of the power transmission line on the basis of the center of the support member, and

a controller controls an amount of vibration of the vibrators according to attached circumstances of the ice and the snow and controls the amount of vibration applied to the power transmission line,

wherein the support member includes;

a first support member covering one side of the power transmission line; and

a second support member that is disposed to face the first support member and covers the other, side of the power transmission line,

wherein the vibrator includes;

a driver disposed at a lower portion of the second support member;

an installer installing the driver on the second support member; and

an eccentric part that is coupled to a shaft of the driver and is eccentrically rotated to generate the vibrations,

wherein the installer includes;

a fixing bracket provided on one side of the driver;

an installing bracket that is coupled to the fixing bracket and is installed at a lower side of the second support member; and

fixing members that pass through the installing bracket and are coupled to the fixing bracket,

wherein the fixing bracket is provided with a first engagement part in a front surface thereof, and the installing bracket is provided with a second engagement part in a rear surface thereof so as to be coupled to the first engagement part,

wherein the first engagement part has a shape of a circular protrusion protruding to the front surface of the fixing bracket or a circular recess recessed in the front surface of the fixing bracket, and

wherein the fixing bracket is provided with a first anti-rotation part in a front surface thereof, the installing bracket is provided with a second anti-rotation art in a rear surface thereof so as to be coupled to the first anti-rotation part, and rotation between the first engagement part and the second engagement part is prevented by part and the second anti-rotation part.

2. The device of claim 1, wherein the first support member and the second support member are mutually fixed by a coupler.

3. The device of claim 2, wherein the coupler includes:

a close contact part that is formed on the first support member and encloses an upper surface of the power transmission line;

a seat part that is formed on the second support member and supports a lower surface of the power transmission line; and

fastening members, each of which is installed on edges of the first and second support members and fixes the first and second support members.

4. The device of claim 1, wherein the installing bracket is inserted into and constrained in a constraint recess formed in a lower surface of the second support member.

5. The device of claim 1, wherein the eccentric part includes:

a fixing block connected to the shaft of the driver; and

an eccentric block that is fixed to an outer circumferential surface of the fixing block and undergoes eccentric rotation.

6. The device of claim 1, wherein the driver is fixed at the lower portion of the second support member by an auxiliary installer.

7. The device of claim 6, wherein the auxiliary installer includes:

a ring member which encloses the driver and both ends of which are inserted into the second support member; and

fastening members that are fastened to the ends of the ring member and fix the ring member to the second support member.
