Description
Technical field
The utility model relates to the live line working field, builds the nest masking device and has its distribution overhead line in particular to a kind of anti-bird.
Background technology
Build nest the northern area birds, breed and mainly concentrate on annual March to June, during this period because Bird's Nest causes 10kV distribution overhead line Frequent Troubles, the safe operation of serious threat circuit has caused huge economic loss to electric power enterprise and user.At present, it is varied that the anti-bird of using on the 10kV distribution overhead line is built the nest measure, affected by various factors, and effect is very little, and the progress of making a breakthrough property is failed in preventing and controlling all the time.Power supply enterprise is in order to reduce bird pest to the impact of line security operation simultaneously, strengthen operational management, increase and make an inspection tour density, drop into a large amount of manpower and materials and remove Bird's Nest, although obtained certain effect, also brought greatly seasonal work pressure to the operations staff, simultaneously in the process of removing Bird's Nest, also easily cause line fault, for hidden danger has been buried in the line security operation.
The technical scheme of prior art and shortcoming: 1, pneumatic type bird-scaring unit: the principle that keeps in dark place, fears look according to birds, the employing natural wind is power, drive pretend to know interruption reverberation that chromium plating stainless steel reflecting piece on axle sends of wind bowl with atwirl wind bowl and reach and drive the bird effect, prevent the purpose that birds are nested, have a rest at the overhead line structures dangerous position.The pneumatic type bird-scaring unit plays certain effect for preventing that birds danger on tower is difficult for nesting, the installation but this bird-scaring unit need have a power failure, and do not having in the weather of wind, the wind bowl can't rotate, and bird-scaring unit also loses flush, goes the usefulness of bird.The phenomenons such as after moving certain hour simultaneously, the partial devices accessory corrosion, weathering occur, fall off, damaged, thus the effect on driving birds of bird-scaring unit lost, near the residential block, easily cause light pollution.
2, supersonic wave bird driving device: this device comprises the parts such as solar panel, radar, eagle model, loud speaker, adopt solar powered, store in advance that birds are wrecked, to meet natural enemy be the warning of sending, sound of call for help etc., be under normal circumstances mute state, in case ultrasonic sensing is when having bird flew near, the sound that will give a warning is driven birds and is perched on shaft tower, reduce the possibility that birds are nested, prevented that birds from nesting in the deathtrap.This device need to have a power failure is installed, and for nest has not played remarkable effect to preventing birds in shaft tower danger at the application initial stage, still use a period of time after birds be accustomed to eagle model and the cry of bird-scaring unit, the dangerous position that begins again on electric pole is nested.Can not effectively frighten for a long time and expel birds, near the residential block, easily cause noise pollution.
3, bird-resistant: solve the difficult problem that birds are nested at the shaft tower dangerous position, on the cross-arm that is placed on high-voltage transmission line pole tower insulator limit, prevent that birds from nesting and stop for a long time on cross-arm, steel wire generally adopts the steel wire of 2 millimeters of diameters, adopt the rotating structure of middle screw, increase elasticity, birds can't be stopped and fly away, from the effect of rear defence bird is installed, this device can prevent effectively that larger birds from stopping in suspension string cross-arm position and have a rest, the erosion of the open-air sleet frost of energy withstand long term exposure dirt has long-term effect on driving birds.But this device needs to have a power failure and installs, and bird-resistant is metallic conductor, the bird thorn needs to form the thorn hat with specific density and area, because 10kV distribution overhead line cross-arm, electric pole and wire space are less, do not satisfy safe distance relatively, if reduce the length of bird-resistant, drive the bird function with what reduce bird-resistant.
4, anti-bird pest cross-arm: by special structural design, make bird not possess the condition of building nest, anti-bird pest effect is remarkable.Product owing to being new research and development does not come into operation on a large scale, and is multiplex in newly-built 10kV distribution overhead line, as the circuit that puts into operation is changed, needs a huge sum of money and needs large tracts of land, the long-time power failure.
5, other anti-bird pest measures among the people: as in position hanging plastic bottle, polybag, birds corpse even.The installation that need have a power failure of this type of way, and hang plastic bottle, polybag, the even measure such as birds corpse, can only play in a short time the flush effect.
