A device for prevention of the buildup of snow of a bird prevention net capable of effectively removing snow or foreign material deposited on the bird prevention net by applying vibration to the bird prevention net is provided. The device prevents damage to property or persons caused by loss of the bird prevention net in advance. The device for prevention of the buildup of snow of a bird prevention net comprises: a support bar(210) secured to the ground at the lower end; a lifting rod(220) connected to the support bar, supporting wires placed on the bird prevention net, ascends to a preset height and freely descends; a moving part(230,240,251,252) raising the lifting rod to the preset height and freely lowering it; an elastic body placed at the lower end to allow the lifting rod which freely descends to vibrate for a predetermined time. The moving part contains a chain(230) which vertically rotates to raise the lifting rod to the preset height and freely lower it, a hooking protrusion(240) formed on one side of the chain and hanging on the groove(221) of lifting rod for a predetermined time and a power generating part for rotating the chain. |
