Abstract
The invention provides a bird preventing device and an overhead line with the bird preventing device. The bird preventing device is installed on the overhead line and is matched with an electric pole of the overhead line. The bird preventing device comprises a shielding plate and a rolling device, wherein the shielding plate is used for shielding a gap between a cross arm and the electric pole of the overhead line and arranged on the cross arm and abuts against the electric pole, and the rolling device comprises a support fixed to the cross arm and roller arranged on the support in a rolling mode. By the adoption of the bird preventing device, the shielding plate is arranged to shield the gap between the cross arm and the electric pole, in this way, tree branches used for nest building can not be inserted in the gap by birds, and supporting points are not available for birds any more; due to the fact that the rolling device is arranged, birds can not stand on the cross arm due to the rotation of the roller, and the purpose of preventing birds from building nests in the overhead line realized.
Description
Technical field
The present invention relates to field of electrical equipment, in particular to a kind of bird proof device and the aerial line with this bird proof device
Road.
Background technology
Build nest, breed the June being concentrated mainly on annual December to next year in northern area birds, during this period because
Bird's Nest causes distribution overhead line Frequent Troubles, the serious safe operation threatening circuit, causes huge to electric power enterprise and user
Big economic loss.At present, it is varied that the anti-bird using on distribution overhead line builds nest measure, affected by various factors,
Effect is little, and preventing and controlling fail the progress of making a breakthrough property all the time.Power supply enterprise is in order to reduce bird pest to line security simultaneously
The impact running, strengthens operational management, increases and makes an inspection tour density, puts into a large amount of manpower and materials and removes Bird's Nest although achieving certain
Effect, but also bring greatly seasonal work pressure to operations staff, simultaneously during removing Bird's Nest, also easily cause
Line fault, is that hidden danger has been buried in line security operation.
The technical scheme of prior art and shortcoming:
1st, pneumatic type bird-scaring unit: the principle of the color that kept in dark place according to birds, fears, is power using natural wind, with atwirl
The interruption reflected light that wind bowl sends with the chromium plating rustless steel reflecting piece in wind symptom bowl rotary shaft reaches bird repellent effect, prevents birds from existing
The purpose that overhead line structures dangerous position is nested, rested.Pneumatic type bird-scaring unit is difficult to have nested for preventing birds danger on tower
To certain effect, the installation but this bird-scaring unit need to have a power failure, and do not having in windy day, wind bowl cannot rotate, and bird-scaring unit also loses
Go the efficiency of flush, bird repellent.After running certain time simultaneously, partial devices accessory occur corrosion, air slaking, fall off, breakage etc. existing
As thus losing the effect on driving birds of bird-scaring unit, for residential neighborhood, easily causing light pollution.
2nd, supersonic wave bird driving device: this device includes the parts such as solar panel, radar, eagle model, speaker, adopts
Solar powered, storage birds are wrecked in advance, meet the warning sending during natural enemy, sound of call for help etc., are in quiet under normal circumstances
Sound-like state, once ultrasonic sensing to have bird flew near when, will give a warning sound, drive birds and perch on shaft tower, reduce
The probability that birds are nested is it is therefore prevented that birds are nested in deathtrap.This device need to have a power failure installation, and at the application initial stage to preventing
Birds are not to nest to serve remarkable effect in shaft tower danger, but after application a period of time, birds get used to the old of bird-scaring unit
Eagle model and cry, the dangerous position starting again on electric pole is nested.Can not effectively frighten for a long time and expel birds, for
Residential neighborhood, easily causes noise pollution.
