Description

The overhead transmission line bird damage prevention device

Technical field

The utility model belongs to anti-bird pest technology, relates to the bird damage prevention device of overhead transmission line.

Background technology

Because people's reinforcement that protection is realized to natural ecological environment and the appearance of forbidding catching and killing the wildlife rules; birds quantity increases gradually; scope of activities also enlarges day by day; birds have been caused great harm to the safe operation of transmission line of electricity; in recent years, some regional electrical networks were owing to the transmission line of electricity tripping operation accident that bird pest causes shows a rising trend.Therefore, must take preventive measures, reduce the bird pest accident, improve power supply reliability.The anti-bird method that the current power transmission circuit is commonly used has following several respects.The one, flush measure: adopt windmill, scarecrow, reflex reflector lens, turnover panel, flush flag, lens type light bird-scaring unit etc., or on shaft tower, hang dead bird or terrified graphics device, and as the 3 D stereo board, can be reflective, and the eyes of flexible rotation are arranged, play the scaring birds.The 2nd, prevent the bird measure: adopt thorn bird device: the multiply steel strand wires are loaded on porcelain vase string top, and steel strand wires and cross-arm are clamped,, make bird not stop falling at this diffusing glomeration of steel strand wires with the ditch wire clamp; Or adopt bird-proof cover, anti-bird baffle plate, as big disk track porcelain vase or composite insulator cover, plastics or glass steel cage etc. are loaded on by first outstanding bottle of cross-arm place, cause line fault to prevent the birds excreta.

Above-mentioned the whole bag of tricks has certain effect in actual use, but still can not stop bird pest.Wherein, the flush device has certain effect at the installation initial stage, easily is accustomed to by birds after long-time the use and loses scaring and drive effect.Especially its unaware function, no matter whether birds are present near space, luminous and sounding types all, the fright effect a little less than.Bird-resistant and bird-proof cover have certain effect in actual use, but it is bulky, have had influence on the service work of trackman on shaft tower.

Summary of the invention:

The utility model provides a kind of electronic type overhead transmission line bird damage prevention device at the defective that above-mentioned prior art exists.It has the whether approaching function of perception birds, is difficult for being accustomed to by birds, has multiple safeguard procedures, and the fright effect is strong, can both protect day and night, and volume is small and exquisite, does not influence the shaft tower maintenance.

To achieve these goals, technical solutions of the utility model have a supply unit, and connection can detect the approaching intrusion detecting sensor of birds, the performance element work of the anti-bird of control.It is made up of sensing unit, power subsystem, performance element republicanism electronic switch four parts.The power line of sensing unit directly is connected with power subsystem; Three parts of performance element are after ruddiness produces circuit, audio-frequency generator, motor and drives the power line of device and be connected in parallel, with the electronic switch polyphone, to be connected to power subsystem; The output of sensing unit is connected with the control end of electronic switch.

Sensing unit is one and invades detecting sensor that for example infrared rays is invaded detecting sensor, ultrasonic is invaded detecting sensor, microwave intrusion detecting sensor.As moving objects such as birds during near this sensor, saltus step can take place in sensor output level, in this device when birds fly near to from 1 to 2 meter of this sensor apart from the time, sensor can detect and make the output level saltus step, make electronic switch closes, thereby connect the power supply of performance element, make performance element work.Power unit is made up of solar cell and accumulator, is used for to whole device power supply.

Advantage of the present utility model and effect: owing to adopted the intrusion detecting sensor, the performance element that can make scaring and drive birds is in peace and quiet and inactive state when no birds are close, have only when birds near the time just move, pointed, scaring and dispersion effect are better than conventional method, be difficult for being accustomed to, can keep anti-bird effect for a long time by birds.

Statistics shows that bird trouble on transmission line fault majority occurs in the time period in night to morning, and conventional prism, reflective mirror flush device are invalid at night, and this device has power supply, makes the luminescence unit of device can be luminous at night, and is still effective at night.

Electro-motor is driven device and is not only played the effect of driveing, just in case some birds ignore and drive signal, when desiring to stop by force to drop on the shaft tower, because motor is driven on the cross-arm that device is installed in insulator chain top, at motor with drive and when arm rotates birds can't be stopped falling in the cross-arm place above insulator chain.

Audio-frequency generator sends the stronger audio signal of loudness of single-frequency, not only plays the scaring effect, and birds are felt sick or pain, and this its sound of feeling bad that makes is difficult for being accustomed to by birds, makes this device have anti-bird pest effect for a long time.

Volume is small and exquisite, can not influence trackman's service work.
