Description

Electric power line pole tower aerofoil bird-scaring unit

Technical field

The utility model relates to a kind of electric power facility, i.e. a kind of electric power line pole tower aerofoil bird-scaring unit.

Background technology

Transmission line of electricity also claims power transmission sequence, is to consist of a plurality of tower and conductors.In the time of on shaft tower, there are birds to nest and perch, easily cause the accidents such as circuit overlap joint short circuit.Therefore, guarantee line security, will prevent that birds from nesting.The measure that past adopts mainly contains electric discharge, luminous, sounding etc.Electric discharge can cause birds injures and deaths, destroys ecology, is prohibited.And acousto-optic equipment was used after a period of time, birds will adapt to, no longer frightened and ineffective.In addition, some comparison in equipments is complicated, easy break-down, be contained in above shaft tower, safeguard more difficult.Therefore, this difficult problem not yet solves so far.

Summary of the invention

The purpose of this utility model is to provide and a kind ofly can not injures birds, can prevent that again birds from nesting on shaft tower, and fairly simple, not fragile, the bird-scaring unit that can use for a long time.

Above-mentioned purpose is realized by following technical scheme: develop a kind of electric power line pole tower aerofoil bird-scaring unit, be characterized in: said bird-scaring unit has the aerofoil of elongated strip, aerofoil is installed on vertical shaft to be rotatably assorted by the axle sleeve at middle part, vertical shaft is arranged on above the cross-arm of shaft tower, the slide bar of the horizontal that is connected below the aerofoil of axle sleeve both sides, the axis of slide bar intersects with aerofoil plate face direction or is vertical, and downside and the cross-arm of slide bar offset, and slide bar two ends are bent to form claw downwards.

The short thorn stretching upwards is equipped with at the middle part of said aerofoil.

Said short thorn has branched, is contained in the outside of minute surface ball, and minute surface ball is contained in vertical shaft upper end.

A plurality of aerofoils are housed above said cross-arm, and the height of adjacent two aerofoils is different, and mutually interts.

On the plate face of said aerofoil, be connected to guide vane.

The beneficial effects of the utility model are: this device is fixed on shaft tower, and aerofoil swings with the wind, can make birds produce fear, dare not approach.Can also sweep the Bird's Nest of having built.And have simple in structure, cheap, working stability, the feature such as easy to use, is expected to become the equipment of overhead line structures indispensability.

Embodiment

The total design of the utility model is that a kind of aerofoil that can wind-force effect lower swing is installed on overhead line structures, by swing, drives away birds, prevents from nesting, and avoids accident.Below in conjunction with accompanying drawing, introduce four kinds of embodiment.

The first embodiment: Fig. 1 Fig. 2 has introduced a kind of aerofoil bird-scaring unit, the main body of this bird-scaring unit is an elongated rectangle aerofoil 1, visible in conjunction with Fig. 3 Fig. 4 Fig. 5: there is an axle sleeve 2 at the middle part of aerofoil 1, and axle sleeve 2 is contained in the outside of a vertical shaft 3, axle sleeve 2 and aerofoil 1 can rotate around vertical shaft 3.Below aerofoil two, be fixed with respectively slide bar 4, slide bar 4 is preferably vertical with aerofoil 1, can certainly intersect at an anglely, is generally not more than 45° angle.Slide bar 4 two ends are bent to form two claws 5 downwards.The length of slide bar 4 can be more than 150mm.

During use, as shown in Figure 6, the lower end of vertical shaft 3 is connected to above the cross-arm 6 of shaft tower 7 to the upper surface of the downside of slide bar 4 contact cross-arm.Like this, aerofoil 1 will be as shown in Figure 7, and at the lower swing that blows of wind-force, slide bar 4 also slides on cross-arm 6 along with the swing of aerofoil, when a side claw 4 touching cross-arm 6, is the extreme position that aerofoil 1 swings.Along with the variation of wind direction, aerofoil 1 also can swing back and forth thereupon.Like this, will frighten birds away, even if nest, also can be turned down by aerofoil.Because the frequency of blowing is very high, and birds build the time of nest and often need the time of growing, thereby can not leave the time of building nest to birds.In recent years, prove by experiment the effect on driving birds highly significant of this bird-scaring unit, can avoid Bird's Nest accident.

The second embodiment: when aerofoil 1 swings, middle amplitude of fluctuation is less, and birds can also be stopped over.For this reason, at aerofoil middle part, be provided with branched short thorn 8, meeting shouting pain flying bird, but can not cause severe injury, more can not injure life.The short thorn 8 representing in figure is contained in the outside of a minute surface ball 9, and minute surface ball 9 can adopt stainless steel to make, and surface-brightening can make flying bird produce fear, dare not approach.

The third embodiment: as shown in Fig. 9 Figure 10, on a cross-arm 6, a plurality of aerofoils 1 are installed, the height of aerofoil is different, mutually interts, and the end of an aerofoil approaches the middle part of adjacent aerofoil, the area of mopping up that can strengthen aerofoil middle part, effect on driving birds is better.

The 4th kind of embodiment: as shown in figure 11, the both sides of aerofoil are provided with the guide vane 10 of outside stretching, extension, its effect is, under same wind direction effect, guide vane 10 be subject to force direction different from aerofoil 1, when aerofoil reaches the limit of position, the stressed of guide vane 10 can disequilibrate, and increases the frequency of aerofoil 1 reciprocally swinging.
