Cause electrical distance not enough, make line tripping.
Conventional bird-proof device has bird-resistant, anti-bird pad, sound expulsion etc., because the adaptability of bird is very strong, the anti-bird action period of these devices is shorter, does not have basic anti-bird effect, and existing anti-bird case is a triangle box body, be arranged on the place that cross-arm birds are easily nested, occupy the space of nesting of birds, but installation method is all adopted and is screwed dead or iron wire colligation etc., installs like this, dismounting inconvenience, be unfavorable for the maintenance to circuit, and the anti-bird case entirety pulled down when overhauling not easily is put.
Therefore, be necessary to improve existing anti-bird case, anti-bird is effective, facilitates installing/dismounting, puts during convenient maintenance.
Summary of the invention
In order to overcome Problems existing in background technology, the utility model proposes the anti-bird case of a kind of electric power line pole tower cross-arm, can facilitate installing/dismounting, during line maintenance, the anti-bird case disassembled can be folded up, conveniently laying, is also convenient to the maintenance of circuit.
For achieving the above object, the utility model is achieved by the following technical solution: described electric power line pole tower cross-arm anti-bird case entirety is triangular prism shaped in one, comprise two inclined-planes, two sides and a bottom surface, inclined-plane and bottom surface are rectangular epoxy resin board, the top edge on two inclined-planes is hinged, the lower limb on two inclined-planes is hinged with two minor faces of bottom surface respectively, bottom surface forms by identical two boards is hinged, two sides are triangle epoxy resin board, three tops of side are provided with static line, the jointed shaft end points place of the jointed shaft on two inclined-planes and inclined-plane and bottom surface is equipped with fixed leg, the anti-bird case of described electric power line pole tower cross-arm is fixed on cross-arm by Fixing clamp-seat, Fixing clamp-seat is " F " type structure that " U " type card and one piece of extension board are formed, " U " type card is bolted on cross-arm angle steel, rivet is fixed together through the baffle on bottom surface and extension board.
Described inclined-plane, side and bottom surface are shiny surface, and inclined-plane is provided with reflective mirror.
The beneficial effects of the utility model: the utility model adopts articulated structure, whole anti-bird case can be made to fold up, facilitate during line maintenance and put, conserve space, use Fixing clamp-seat conveniently to installation and the dismounting of anti-bird case, to reduce labor intensity, installing reflective mirror can make anti-bird better effects if, make bird not near cross-arm place, for transmission line safe and stable operation is taken a firm foundation.
