Description
Technical field
The utility model relates to power industry overhead transmission line electrical safety class auxiliary equipment, and specifically one is convenient to the anti-bird gear case of field-installed pair of cross-arm, for preventing overhead transmission line bird pest.
Background technology
Overhead distribution is larger by the impact of birds activity, the structure of distribution line shaft tower and present position are well suited for the birds such as magpie and build a nest, particularly in circuit by two parallel and two cross-arms of close together, its plane formed is comparatively large, is the preferred location that birds are built a nest.Because Bird's Nest is many near the electrical body such as wire, disconnecting link, the activity of birds is easy to cause the accident such as short circuit, tripping operation, causes serious threat to the safe operation of electrical network.In recent years, bird pest has become one of distribution line major failure factor.
Scarer common at present mainly contains honourable bird-scaring unit, voice bird-scaring unit, supersonic wave bird driving device, bionical natural enemy bird-scaring unit, chemical bird repellent, bird thorn etc., all to expel for the purpose of birds, as honourable bird-scaring unit adopts windmill-type structure, blade establishes reflective mirror, larger to the dependence of wind-force and light, soon aging, service life is short; Bionical natural enemy bird-scaring unit transfixion can be penetrated by birds very soon; The sound that voice bird-scaring unit imitates shot or birds natural enemy drives bird, there is noise pollution, can not be used for residential block; Supersonic wave bird driving device cost higher (3 ~ 5 times of normally honourable bird-scaring unit), uses middle discovery birds to ultrasonic and insensitive, and actual effect on driving birds is general; Bird thorn is the acupuncture of radiation metal, can only locally prevent birds from landing, and self-conductive, be not suitable for electric closely spaced distribution line.
Also there is a problem in said apparatus, after namely using a period of time, birds will adapt to gradually and no longer fear, and it drives the reduced capability of bird, and the mode of driveing simple as seen can not prevent bird pest completely in actual use.Especially for two cross-arm shaft tower, its effect of driving anti-bird declines greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of bird-proof device for overhead transmission line, prevents birds from nesting in the parallel double cross-arm position of overhead line structures.
The purpose of this utility model is achieved through the following technical solutions:
Be convenient to the anti-bird gear case of field-installed pair of cross-arm, comprise side plate, base plate, end plate and linkage, end plate is triangular in shape, and side plate and base plate are rectangle, linkage is that two hinge monomers are articulated and connected, and each hinge monomer is equipped with the draw-in groove for end plate, side plate and base plate described in plug-in mounting;
Two end plates, two blocks of side plates and one piece of base plate connect and compose triangular prism structure casing, the edge of end plate, side plate and base plate and the draw-in groove snap fit of each hinge monomer of hollow by multiple linkage.
Further, described end plate is isosceles triangle.
Further, the drift angle of described triangular end plates is 60 ~ 90 degree.
Further, the hinge monomer semicircular in shape of described linkage, the straight flange of two hinge monomers is hinged, and draw-in groove is opened on the curved edge of hinge monomer.
Further, the hinge monomer sidepiece of described linkage is provided with fixing hole.
Further, described base plate Corner Strapped has the permanent magnet for adsorbing angle cross arm.
The beneficial effects of the utility model are: simple and reasonable, with low cost, overcome existing defect of driving bird product, long service life, easy disassembly; And the two cross-arm sizes be convenient to according to shaft tower, field fabrication, assembling, and by permanent magnet and screw, this device is fixed on the twin beams top of cross-arm, occupy the space that birds take nest, the ridge-shaped top that its two blocks of side plates are formed, can effectively prevent birds from perching, realize hindering generation and drive, thoroughly prevent birds to build a nest on cross-arm.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is linkage structure chart of the present utility model;
Fig. 3 is working state figure of the present utility model.
Embodiment
In figure: 1, side plate, 2, base plate, 3, end plate, 4, linkage, 4a, hinge monomer, 4b, draw-in groove, 4c, fixing hole, 5, electric pole, 6, two cross-arm.
Embodiment
From Fig. 1 ~ Fig. 2, technical solutions of the utility model comprise two blocks of side plates 1, one piece of base plate 2, two end plates 3 and linkage 4, and end plate 3 is triangular in shape, and side plate 1 and base plate 2 are rectangle, linkage 4 is that two hinge monomer 4a are articulated and connected, and each hinge monomer 4a is equipped with draw-in groove 4b; Described hinge monomer 4a semicircular in shape, the straight flange of two hinge monomer 4a is hinged, and draw-in groove 4b is opened on the curved edge of hinge monomer, and its semicircular socket (curved edge) is convenient to the plug-in mounting of insulation board.
End plate 3, side plate 1 and base plate 2 connect and compose the triangular prism body structure of hollow by multiple linkage 4, and its connected mode is side plate 1, base plate 2, end plate 3 edge are inserted in the draw-in groove 4b of each hinge monomer 4a.
Angle between two blocks of described side plates 1 is 60 ~ 90 degree.
The hinge monomer 4a sidepiece of described linkage is provided with fixing hole 4c, and this fixing hole can be made into screwed hole, and rigging screw or jackscrew are used for the fastening sheet material (each side plate, base plate and end plate) be inserted in hinge monomer.
Below describe the fabrication and installation of this device in detail, the epoxy resins insulation plate selecting 3mm thick is main material.Due to two cross-arm positions of different size electric pole, the differences such as size, therefore the length according to cross-arm two on electric pole 5 and width is first needed, epoxy resins insulation plate is cut into the rectangular side panels of two pieces of area equation, one piece of rectangular base plate and two pieces of isosceles triangle end plates, and the insulation board of well cutting is inserted respectively the draw-in groove 4b of each linkage, utilize multiple linkage that each plate Connecting groups is dressed up triangular prism shape casing that cross section is isosceles triangle, its two pieces of interpleural angles (i.e. angles between two stringcourses of isosceles triangle end plate) according to circumstances can select (linkage is convenient to regulate the angle between each plate) within the scope of 60 ~ 90 degree.The area of awful weather can be set up jackscrew and reinforce in the fixing hole 4c of hinge monomer 4a.
