Abstract
The utility model provides a thirty-five kV concrete pole line cross arm bird prevention cover, and relates to an electric power transmission line device. A bird prevention cover body is provided with a spherical surface, a semicircular groove is formed in the contact part between the bird prevention cover body and a concrete pole, a sealing panel and a sliding iron rail are arranged at the bottom of the bird prevention cover body, a fixing plate with a bolt hole is arranged on the upper portion of the sealing panel, and sliding chutes are formed in two pieces of sliding iron. The thirty-five kV concrete pole line cross arm bird prevention cover is scientific and reasonable in structural design, low in manufacturing cost, good in insulativity and not prone to damage, a gap between the concrete pole and a cross arm can be effectively blocked, and therefore line tripping faults caused by bird nesting are effectively avoided, power supply reliability of a line is improved, and safe and reliable operation of the line is guaranteed.
Description
Technical field
The utility model relates to a kind of power transmission line pipeline equipment.
Background technology
The line tripping that bird pest causes frequently occurs, the line fault that reinforcement circuit operational management reduction bird pest causes is our groundwork, in recent years social environment good, it is fast that bird breeds, bird has very strong adaptive capacity and love nest habit, the speed of building Bird's Nest is amazing, bring very large hidden danger to our circuit, we also find that in tour bird builds the rule of Bird's Nest, our circuit cross-arm is parallel installation, cross-arm and shaft tower have certain space, bird utilizes this space can build soon a nest, the material of building bird's nest has iron wire, welding rod, wet branch is easy to cause line-to-ground or tripping operation.
Summary of the invention
The purpose of this utility model is to provide a kind of 35kV cement pole circuit cross-arm bird-proof cover, builds bird's nest and causes the problem such as line-to-ground or tripping operation to solve prior art.
It is that bird-proof cover body is sphere that the utility model solves the technical scheme that its technical problem adopts, the part that bird-proof cover body contacts with cement pole is semi-circular recesses, sealing panel and sliding rail track are arranged at bird-proof cover body bottom, sealing panel top has the fixed head in strap bolt hole, sliding rail is connected as a single entity with fixed head with bolt, chute is set in sliding rail, and sliding rail end is bent to form clamping part, and grip bolt is set on clamping part.
Adopting good effect of the present utility model is that scientific structure design is reasonable, cost of manufacture is low, good insulating, not fragile, the effectively space of plugging cement bar and cross-arm, thereby the generation of the line tripping fault of effectively having avoided birds to nest and to cause, improve the power supply reliability of circuit, guaranteed the safe and stable operation of circuit.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model upward view;
Fig. 3 is the utility model end view.
1 grip bolt, 2 clamping parts, 3 sliding rails, 4 bird-proof cover bodies, 5 grooves, 6 chutes, 7 sealing panels, 8 sliding rail tracks, 9 fixed heads in figure.
Embodiment
As shown in the figure: bird-proof cover body 4 is sphere, the part that bird-proof cover body 4 contacts with cement pole is semi-circular recesses, sealing panel 7 and sliding rail track 8 are arranged at bird-proof cover body 4 bottoms, sealing panel 7 tops have the fixed head 9 in strap bolt hole, sliding rail 3 is connected as a single entity with fixed head 9 with bolt, chute 6 is set in sliding rail 3, and sliding rail 3 ends are bent to form clamping part 2, and grip bolt 1 is set on clamping part 2.
