Abstract
The invention discloses a bird preventing needle plate of an electric transmission line. The bird preventing needle plate comprises a lower-layer insulation plate and an upper-layer insulation layer stacked mutually and fixedly connected with each other, wherein a plurality of bird preventing needles are vertically arranged on the board of the lower-layer insulation plate; U-shaped stop bases are fixed on the board of the upper-layer insulation plate; the opening directions of the U-shaped stop bases are perpendicular to the length directions of the bird preventing needles. The bird preventing needle plate of the invention is mounted above an insulator, uses the sharpness and coverage area of the bird preventing needles to force birds to not stop or even nest in the dangerous positions of towers to achieve the bird expelling purpose, and can be operated for a long time; an insulation base avoids possible short-circuit hidden dangers when dropping.
Description
Technical field:
The present invention relates to a kind of transmission line bird-proof needle plate.
Background technology:
Electric power line pole tower is tall and big firm, and a lot of birds are liked the breeding of nesting in the above, especially often Bird's Nest are built to the danger positions such as skewed crossing place above shaft tower insulator string hitch point and above wire jumper.When causing line tripping accident during three kinds of situations below occurring: the materials of nesting such as (1) branch, iron wire are sagging or fall, short circuit insulator string, and such fault is not easy to search; (2) the birds ight soil of perching above shaft tower falls to polluting insulator, reduces line insulation level, and run up to and to a certain degree cause flashover, or all or part of insulator of ight soil whereabouts moment short circuit, the frequency that such accident occurs is the highest; (3) birds that build is larger are movable on cross arm of tower, and the moment of spreading the wings is by insulator string short circuit.The flashover tripping operation that the annual birds that all can occur some at home and abroad cause.The America & Canada large area blackout occurring for 2004, cause is exactly that ultra-high-tension power transmission line birds droppings flashover causes tripping operation, causes system concussion, off-the-line.
The main anti-bird measure of taking at present has: (1) installs bird-resistant.Bird-resistant is the most frequently used scarer, be umbrella, developed area is larger, and also larger to the protected area of insulator, price is low, install more convenient, early stage, effect was better, but easily aging, aging rear weak effect, and because of dismounting difficulty after corrosion, and there is the situation that birds are directly nested on bird-resistant; (2) anti-bird windmill is installed.Anti-bird windmill mainly consists of rotary reflective device and the holder device of metal material or glass-mirror, constantly rotation under the effect of wind-force, by mirror-reflection light, reach and drive bird, prevent the object that birds are nested, have a rest at overhead line structures dangerous position, but at calm weather, windmill cannot rotate, also just lost the usefulness of driving bird, the discovery of field investigation is simultaneously after installing a period of time, and part rolling bearing very easily damages and causes windmill rotate difficulty or stop.(3) supersonic wave bird driving device is installed.Adopt solar poweredly, once sense that birds are near the sound that will give a warning, Stimulation of Birds, to reach the object of driving bird, but is used after a period of time, birds gradually habituation after warning tones, also just lost effect.In addition strengthen insulator cluster parachute, manually stepping on bar, to remove Bird's Nest etc. be all also the anti-bird measure of using, although above-mentioned several different methods respectively has feature, also played certain effect, all has certain drawback, all can not effectively prevent the generation of bird pest.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of transmission line bird-proof needle plate, improve the corresponding shortcoming of prior art, bird-proof needle plate of the present invention is arranged on to insulator top, utilize the sharp and area coverage of its bird-proof needle, force birds cannot stop even and nest at shaft tower danger position, thereby reach the object of driving bird, and can long-play, the short circuit hidden danger that may exist when insulator foot has also been avoided falling.
Technical solution problem of the present invention adopts following technical scheme:
Transmission line bird-proof needle plate, it comprises: the lower floor's insulation board and the upper strata insulation board that overlap each other and be fixedly connected with, on the plate face of described lower floor insulation board, many bird-proof needles have been arranged vertically, on the plate face of described upper strata insulation board, be installed with U-shaped deck, the opening direction of described U-shaped deck is perpendicular to the length direction of described bird-proof needle.
Between described lower floor insulation board and described upper strata insulation board, with rivet, be fixedly connected with.
Be provided for described bird-proof needle plate to be fixed on the securing member on cross arm of tower, described securing member comprises: cross section is the tabular shackle member of U font, at a nut that free-ended middle part is fixed with bolt and mates with bolt of described shackle member; The plate face of described lower floor insulation board and upper strata insulation board is provided with the bolt hole mating with described bolt.
Between described bolt and the free end of described shackle member, be also fixed with stainless steel band.
The large end section of described bird-proof needle is trapezoidal, is provided with a plurality ofly for assembling the trapezoidal hole of described bird-proof needle on the plate face of described lower floor insulation board, and the large end of described trapezoidal hole is towards insulation board place, described upper strata one side.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Upper strata of the present invention insulation board and lower floor's insulation board are made by insulating material; even if accidentally come off, can between wire and shaft tower, not form short circuit yet; bird-proof needle needle point is sharp; birds can not be based oneself upon; material is stainless steel; can not get rusty, the area coverage of formation is protected below insulator effectively.Anti-bird effect is remarkable, has effectively protected below insulator; Easy accessibility, has insulation protection; Can long-play.
Accompanying drawing explanation:
Figure 1A, 1B, 1C are respectively front view, left view and the vertical view of bird-proof needle plate; Fig. 2 A, 2B are front view and the vertical view of securing member; Fig. 2 C, 2D are front view and the vertical view of another securing member.
Number in the figure: 1 upper strata insulation board, 2 lower floor's insulation boards, 3 bird-proof needles, 4 is U-shaped deck, 5 rivets, 6 shackle member, 7 bolts hole, 8 stainless steel bands, 9 bolts.
Below pass through embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment:
Embodiment: referring to Figure 1A-1C, the transmission line bird-proof needle plate of the present embodiment, it comprises: the lower floor's insulation board 2 and the upper strata insulation board 1 that overlap each other and be fixedly connected with, on the plate face of lower floor's insulation board 2, many bird-proof needles 3 have been arranged vertically, on the plate face of upper strata insulation board 1, be installed with U-shaped deck 4, this U-shaped deck is for being fixed on cross arm of tower by bird-proof needle plate, and the opening direction of U-shaped deck is perpendicular to the length direction of bird-proof needle.In specifically arranging, the quantity of bird-proof needle can be set to 100 left and right, and dense degree is to stop birds to stop over and be advisable on insulation board.
