Detailed Description

Referring to fig. 1 and 2, the utility model relates to a first embodiment of bird damage prevention device of wire pole cross arm, including triangle-shaped main part 41, be equipped with one row of interval distribution's spine 42 and be used for with the fixed coupling mechanism of wire pole cross arm in this triangle-shaped main part 41 apex angle one end and bottom surface distribution, this triangle-shaped main part 41 is made by stereoplasm insulating material, this spine 42 and triangle-shaped main part 41 structure as an organic whole, or the metal spine of embedding this triangle-shaped main part 41 apex angle.

In the first embodiment, a middle plate 47 is arranged in the middle of the triangular main body 41; a necking is arranged on the bottom surface of the triangular main body 41, the two sides of the necking are respectively a wide side 45 and a narrow side 46, the width of the wide side 45 is larger than that of the narrow side 46, at least two nuts or screw holes 44 (the nuts are equivalent to lengthened screw holes) are arranged on the wide side 45, and fastening bolts 43 are arranged; the wide side 45, the narrow side 46, the middle plate 47, the nut or the screw hole 44 and the fastening bolt 43 constitute the connecting mechanism, and the connecting mechanism is suitable for being mounted on an angle iron cross arm (steel cross arm without the reinforcing angle 11 in fig. 2) or an insulating cross arm with the same shape as the angle iron cross arm (insulating cross arm with the reinforcing angle 11 in fig. 2).

Referring to fig. 3 and 4, the connecting mechanism of this embodiment is different from the previous embodiment in that the connecting mechanism includes a U-shaped bayonet 48 and fastening bolts 43, the opening of the U-shaped bayonet 48 faces downward and is connected to two sides of the bottom surface of the triangular main body 41, nuts 44 (corresponding to screw holes) are connected to the outer side of one or two sides of the U-shaped bayonet 48, and one fastening bolt 43 is mounted at the outer end of each nut or screw hole 44. The connecting mechanism is suitable for being mounted on a cross arm (mainly an insulating cross arm) with a rectangular cross section.

Referring to fig. 5 and 6, the connection mechanism of this embodiment includes a clip formed of two opposite L-shaped catching arms 49, the top ends of the catching arms 49 are hinged to both sides of the bottom surface of the triangular body 41 by means of pins 40, the lower ends of the catching arms 49 are bent downward and provided with through holes, and fastening bolts 43 are inserted through the through holes at the lower ends of the two catching arms 49 to be connected with nuts 44.
