Device for overhead transmission line laser drives bird relates to transmission line and drives bird technical field, is provided by work main part and power and constitutes, and the work main part includes laser pipe array unit, laser pipe drive power supply group and observes and controls the unit, laser pipe array unit sends hollow ring form light beam, by annular base and arrange that annular base is inside to be a plurality of laser pipe that ring array arranged and to constitute in, laser pipe drive power supply group provides the laser pipe and lights the power, it starts to observe and control unit send instruction control laser pipe drive power supply group. The utility model discloses a miniwatt single tube laser pipe to the installation of ring array's mode forms the hollow light beam, makes birds in flight or stop the in-process, and the optical wand of seeing that can be very obvious attacks to it, and the light beam of scanning makes the region that birds avoided needing protection. And lower powered laser need not to expand and restraints very big light beam diameter, can reach the light beam diameter that needs after the aggregate erection, can realize that high power laser forms the effect of light beam.
