Description
Technical field
This utility model relates to electric power overhead transmission line operation maintenance field, particularly relates to the anti-bird pest field of transmission line of electricity.
Background technology
In recent years; along with mankind's reinforcement to natural ecological environment protective awareness; the procreation quantity of birds increases gradually; range of activity expands increasingly; many birds are nested breeding on electric power line pole tower; high risks is caused to the safe operation of transmission line of electricity; statistics in recent years shows; the line fault caused due to birds activity is only second to damage to crops caused by thunder and external force destruction; occupied line fault sum the 3rd, the line tripping fault that bird pest causes has become affects the key factor that electric power safety produces.
The harm form of overhead power line is mainly had by birds: birds are nested, Bird Flight and birds droppings flashover three kinds, and this flashover fault that wherein birds droppings flashover causes accounts for the overwhelming majority in bird pest.Birds droppings flashover refers to the flashover fault caused by the birds Excreta perched on shaft tower.Birds droppings pollutes insulator chain, there was dampness in the air, dense fog time easily there is flashover.Bird stand in the cross-arm on porcelain vase string (or silicon) top voids excreta downwards along bottle string dirty time cause single-phase earthing, or birds droppings blows to electrical body with the wind and causes the air gap to puncture, and causes flashover.Main Prevention method currently for birds droppings flashover has installation bird-resistant, bird-proof cover and adopts bird frightening device etc..
The middle installation bird-proof cover that works at the scene is to adopt relatively more anti-bird measures of one.But existing bird-proof cover volume is big, charged install when tower carries owing to pole tower operation space is little, carry inconvenience.After bird-proof cover installs simultaneously, when shaft tower maintenance needs upper and lower insulator chain, due to blocking of bird-proof cover, need repeated disassembled and assembled bird-proof cover, add the burden of operating personnel.In addition, if 220kV straight cement pole installs bird-proof cover, owing to cement cross-arm is relatively large in diameter, it is impossible to charged installation on tower, the lower insulator chain that can only have a power failure is installed, but owing to bird-proof cover blocks after installing, operating personnel is difficult to return on shaft tower.

In an embodiment of the present utility model, can be connected by arranging multiple bolt 13 between the first shutter 1 and the 3rd shutter 3.Specifically, between the first shutter 1 and the 3rd shutter 3, along the first shutter 1 and the 3rd shutter 3 edge can be arranged symmetrically multiple bolt aperture 11 and multiple nut perforate 12, among bolt aperture 11 and nut perforate 12, load bolt 13 first shutter 1 and the 3rd shutter 3 are coupled together.In addition, in an embodiment of the present utility model, as it is shown in figure 1, the first to the 6th shutter 1,2,3,4,5,6 edge is provided with closed seamless gap when sealing strip 7 makes each portion connect, it is prevented that birds droppings is dripped by gap.
In sum, shutter 1,2,3,4,5,6 connects into overall structure by latch 9, insulation turn plate hinge 8 and bolt 13.First shutter 1 and the 3rd shutter 3 combine back wall and are installed on the bulb gold utensil 17 of insulator chain 18 around forming cylindrical hole nest, as shown in Figure 2.In the present embodiment, shutter 1,2,3,4,5,6 outer edge corner angle circular arc chamfering, it is combined into disc bird-proof cover.In other embodiments, each shutter can optionally be combined into other shape, and therefore, bird-proof cover of the present utility model is not limited to the disc shown in Fig. 1.
As it has been described above, latch 9 is for controlling the folding of the second shutter the 2, the 5th shutter the 5, the 4th shutter the 4, the 6th shutter 6.Describe how latch 9 realizes this control below in conjunction with Fig. 2 and Fig. 3.First illustrating to install the open configuration of bird-proof cover after bird-proof cover on shaft tower according to an embodiment of the present utility model in conjunction with Fig. 2, namely bird-proof cover is playing the state of protective action.Referring to Fig. 2, the bird-proof cover of embodiment of the present utility model is arranged on via cylindrical hole nest on the bulb gold utensil 17 of the insulator chain 18 of cross arm of tower 15.Insulator chain 18 is connected with cross arm of tower 15 via bulb gold utensil 17 and U-bolt 16.After latch 9 closes, integrally-built shutter 1 is connected into by insulation turn plate hinge 8 and bolt 13, 2, 3, 4, 5, 6 present level, second shutter 2, 5th shutter 5, 4th shutter 4, maintenance level cannot be sagging under the effect of insulation turn plate hinge 8 for 6th shutter 6, and owing to now latch 9 closes, second shutter 2, 5th shutter 5, 4th shutter 4, 6th shutter 6 cannot move up, so prevent owing to wind action is the second shutter 2, 5th shutter 5, 4th shutter 4, 6th shutter 6 upwards blows afloat.Therefore, after latch 9 closes, bird-proof cover entirety under the effect of latch 9 and insulation turn plate hinge 8 presents horizontal open configuration, and each shutter will not be sagging without moving up, so each shutter is locked, and transmission line of electricity can be played protective action by bird-proof cover well.
Illustrate on shaft tower, to install the folded state of bird-proof cover after bird-proof cover according to an embodiment of the present utility model in conjunction with Fig. 3 below, for instance, when overhaul, bird-proof cover is folded up convenient maintenance by operating personnel.Usual bird-proof cover presents open configuration as shown in Figure 2 when playing protective action, and latch 9 is Guan Bi, and each shutter is locked.When operating personnel's upper and lower shaft tower for maintenance, latch 9 can be opened by maintainer, thus the second shutter the 2, the 5th shutter the 5, the 4th shutter the 4, the 6th shutter 6 can be folded up, shrink by bird-proof cover, to facilitate the upper and lower shaft tower of maintainer.In an embodiment of the present utility model, when latch 9 is opened, maintenance level cannot be sagging under the effect of insulation turn plate hinge 8 for second shutter the 2, the 5th shutter the 5, the 4th shutter the 4, the 6th shutter 6, but owing to now latch 9 is opened, second shutter the 2, the 5th shutter the 5, the 4th shutter the 4, the 6th shutter 6 is except can keeping level, it is also possible to present folded state.Folded state be will be described below.Specifically, referring to Fig. 3, after latch 9 is opened, the 5th shutter 5 can flip up on the second shutter 2 via insulation turn plate hinge 8, and the 5th shutter 5 and the second shutter 2 can flip up on the first shutter 1 via insulation turn plate hinge 8 after being folded together；6th shutter 6 can flip up on the 4th shutter 4 via insulation turn plate hinge 8, and the 6th shutter 6 and the 4th shutter 4 can flip up on the 3rd shutter 3 via insulation turn plate hinge 8 after being folded together.Therefore, after six shutters 1,2,3,4,5,6 are folding, the reduction of whole bird-proof cover volume can the upper and lower bird-proof cover of convenient working personnel.Operating personnel can by turning down the second shutter the 2, the 5th shutter the 5, the 4th shutter the 4, the 6th shutter 6 and Guan Bi latch 9 by bird-proof cover recovery to the protection state shown in Fig. 2 after returning shaft tower.
Therefore, be can be seen that by the description of above-described embodiment, folding bird-proof cover of the present utility model is while playing anti-bird effect, upper and lower tower is installed easy to carry, bird-proof cover installs rear operating personnel and just can conveniently return after folding for bird-proof cover, need not repeated disassembled and assembled bird-proof cover again when upper and lower insulator chain overhauls.Folding bird-proof cover of the present utility model is practical, carries with easy for installation, can play anti-bird effect, does not affect again the upkeep operation on transmission line of electricity, economical and practical.
The above is only detailed description of the invention of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
