Description
Technical field
The utility model relates to a kind of ultrasonic generator, and particularly relate to a kind of for driveing the supersonic wave bird driving device of birds away from overhead transmission line equipment, its structure is external, and emission angle is adjustable.
Background technology
At present, the overhead transmission line equipment of Ge Jia Utilities Electric Co. is primarily of this several main line composition of 110KV circuit, 35KV circuit and 10KV circuit, the tortuous spider net type distribution of these circuits, Nei Gejia enterprise of district, unit and residential electricity consumption are supplied, thus these overhead transmission lines run whether stablize the electricity consumption situation directly having had influence on regional enterprise, unit and resident.
Along with the progress of scientific and technological level, overhead transmission line equipment under prior art itself fastness and reliability grow with each passing day, unless there is the situation of strong natural calamity weather, regular maintenance at ordinary times just can ensure the operation of overhead transmission line equipment long-term stability, but, also there is uncontrollable loss factor in existing overhead transmission line equipment, wherein maximum uncontrollable loss factor is exactly along with progressively improvement and the people of natural environment like that bird protects the enhancing of bird consciousness, the quantity of birds and population present to be increased year by year, the behavior of birds has but threatened power equipment safety and has run reliably.Because birds are liked the electric line of pinnacled overhead transmission line equipment and equipment are nested and defecation, because these birds rank picks up the objects such as branch, iron wire, faggot, flight is passed through on the line between sky or wire, when the metal objects such as iron wire drop between cross-arm and wire, line fault will be caused.And when strong wind weather or birds are movable in nest, the movement of iron wire sometimes also can be touched overhead transmission line or produce electric discharge with overhead transmission line because of hypotelorism, this all can cause circuit single-phase earthing or line to line fault thus cause line tripping, and the pollution insulator edge of bird excrement instantaneously can shorted section air duct, air dielectric is worsened, very easily form the arcing short circuit electric discharge between full skirt, arcing fault occurs.Though sometimes line flashover fault can not be caused immediately, but As time goes on, the pollution of insulator chain is more and more heavier, there was dampness in the air, dense fog time that the phenomenon of the failure of line insulator flashover very easily occurs is too numerous to mention especially, the electric line and the equipment fault which results in overhead transmission line equipment are of common occurrence.In order to improve reliability and the safety of equipment for power transmission and distribution, necessary measure is taked to drive when not injuring birds with regard to needing.
And due to bird pest fault be fault type more common in overhead transmission line fault, different from other faults, there is certain randomness, disguise and cumulative, not by any manual control, but but can cause very important impact to the normal operation of circuit, if the March of southern area is to May, the migratory bird migrated can be welcome, birds activity is increased, also makes this kind of fault occur many
And in order to solve the problem, under prior art, also taked manpower to drive and install additional the way of bird-scaring unit, but these ways are fed back through on-the-spot for a long time, and its result is not satisfactory, and main cause is:
1. manpower is driven and is investigated bird's nest, emphasis investigation is carried out to the circuit of severely afflicated area, one is found to clear up one, accomplish zero bird's nest on trolley line thus reduce the line fault because Bird's Nest causes further, this way wastes time and energy very much, manpower is driven almost useless, and in the peak period of avian reproduction, the forward foot in a step has just been driven and investigated bird's nest.The rear foot has again birds to stand to nest.
2. install bird-scaring unit additional and drive bird, the mainly Wind bird scaring device of the bird-scaring unit under prior art, this bird-scaring unit utilizes wind-force to rotate, thus plays the effect of driveing birds.Nesting according to migratory bird likes with vicinal principle, the shaft tower at Bird's Nest place and had the shaft tower of Bird's Nest to install this bird-scaring unit respectively for passing several years.Just start effect really good, but find problem gradually afterwards.Wind bird scaring device can play more effective dispersion effect on straight line pole, but in complex device and the more shaft tower of cross-arm, just cannot play good effect on driving birds, although and there is no Bird's Nest installing this block cross-arm of bird-scaring unit when finding that there is, migratory bird can again start to nest on lower floor's cross-arm.So Wind bird scaring device effect on driving birds on single straight line pole is better, but effect on driving birds is poor on baroque equipment and the more shaft tower of cross-arm, and Wind bird scaring device function is too single.
3. adopt novel supersonic wave bird driving device, supersonic wave bird driving device, according to bionics principle, utilizes singlechip technology to realize transformation mechanism that is frequently fixed and frequency sweep.Sent the ultrasonic of different frequency by supersonic generator, birds living environment is worsened, makes it the sphere of action away from bird-scaring unit.But, through use after a while, the electric pole partly installing this type of bird-scaring unit has found Bird's Nest again, supersonic wave bird driving device has omnibearing effect on driving birds, but still there is this situation why, this is relevant with the architectural characteristic of supersonic wave bird driving, the transmitter of supersonic wave bird driving device is all be built in Rainproof louver window, when ultrasonic occurs, according to the feature of ultrasonic high directivity, so mainly can two parts be divided into: a part of ultrasonic is not launched away due to reflex in Rainproof louver window, finally be consumed in the inside of supersonic wave bird driving device casing, do not play and any drive bird effect, the ultrasonic of another part then by the guide effect of Rainproof louver window oliquely downward spread out go, such result just cause supersonic wave bird driving device horizontal direction and above obtain the ultrasonic of very little energy, even there is no ultrasonic, relatively strong ultrasonic is obtained in the oblique below of supersonic wave bird driving device, after tested, energy is lower than 80% (inside wastes about 20%) of expected energy, therefore the effect on driving birds of supersonic wave bird driving device is sometimes not fully up to expectations.
In sum, as why not allow the safety and stability of bird damage circuit be current Ge Jia Utilities Electric Co. the problem that will urgently solve.
Utility model content
