Description
Technical field
The utility model relates to the bird-proof device for overhead power transmission line pole tower, belongs to field of electrical equipment.
Background technology
Bird-proof device on overhead transmission line is part important on overhead transmission line.Along with the fast development of national economy, the whole society has higher requirement for the safe and high quality service of power system.Be subject to for a long time the impact of natural world birds activity due to power circuit, and the overhead transmission line tripping operation fault causing, it directly has influence on the safe and reliable economical operation of transmission line of electricity.In recent years, the flashover tripping operation fault that transmission line of electricity causes because of bird pest constantly increases, and the activity of birds has formed and had a strong impact on the stable operation of electrical network.Overhead transmission line operates in field, wilderness mostly, its broad covered area, and ecotope is changeable again, will be subject to undoubtedly the impact of birds activity on it.
Birds are the harm of overhead power line
Birds are nested:
Birds In Spring starts on electric power line pole tower, to nest, hatch.Through site observation, be mostly the birds such as crow, blue or green stork, goshawk.These bird mouths are held the things such as branch, iron wire, faggot in the month, pass through on the line flight between sky or wire, when the things such as iron wire drop between cross-arm and wire, will cause line fault.While blowing, the Bird's Nest on shaft tower is blown to four winds and drops on live wire or outstanding bottle, can cause short circuit grounding fault.
Bird Flight:
The birds that the bodily form is larger, as black stork, its body is long more than 1 meter, and wing launches larger.When the birds that the bodily form is larger are fought in the air, flight may cause phase fault or singlephase earth fault between wire.
Birds droppings flashover:
Birds droppings flashover refers to the flashover fault being caused by the birds excreta of perching on shaft tower.The birds droppings dung that particularly blue or green stork has loose bowels pollutes insulator chain, and flashover easily occurs there was dampness in the air, when dense fog.Bird stands in and on the cross-arm on porcelain vase string or silicon top, has loose bowels dung downwards and cause single-phase earthing when dirty along bottle string, or birds droppings blows to the wind electrical body and cause the air gap to puncture, and causes flashover.
Harm for above-mentioned birds to transmission line of electricity, existing bird-proof device has bird-resistant, bird-preventing plate, supersonic wave bird driving devices etc. but bird-resistant can damage birds, run counter to the theory watching for animals, and bird-preventing plate can not prevent that birds from nesting.After supersonic wave bird driving device application a period of time, birds habituation after the eagle model and horrible cry sound of bird-scaring unit, start again dangerous position on shaft tower and nest and can not permanently effectively frighten, expel birds and nest at the dangerous position of shaft tower, thereby cannot reach the generation of effectively controlling bird pest fault.Therefore existing anti-bird pest measure cannot effectively reduce the nest rate of birds at overhead line structures dangerous position, can not meet production requirement.
Utility model content
The present invention is in order to solve existing bird-proof device in anti-bird, the problem that birds are damaged, and the utility model provides a kind of overhead transmission line bird proof device.
A kind of overhead transmission line bird proof device, it comprises bracing frame, a N rotating shaft and N reflective plate; Described N is positive integer;
The longitudinal cross-section of described bracing frame is spill, on former and later two sidewalls of bracing frame, be equipped with N through hole, and the through hole on each sidewall is all uniformly distributed along straight line, and the through hole on two sidewalls is oppositely arranged, distance on each sidewall between adjacent two through holes is greater than the width of reflective plate
N rotating shaft passes respectively the N forming on former and later two sidewalls of bracing frame to through hole, and rotating shaft and through hole are slidably connected, and the length of rotating shaft is greater than the vertical range between former and later two sidewalls of bracing frame,
The length of reflective plate is less than the vertical range between former and later two sidewalls of bracing frame, reflective plate is between former and later two sidewalls of bracing frame, N rotating shaft is separately fixed on the center line of N reflective plate, and ensures that the distance between two adjacent reflective plates is greater than 0.
It also comprises N wind wheel, and the center of a described N wind wheel is fixedly connected with one end of N rotating shaft respectively, and distance between wind wheel and bracing frame sidewall is greater than 0, and in same plane, N rotating shaft is arranged in parallel.
Described N is more than or equal to 5 integer.
A kind of overhead transmission line bird proof device described in the utility model can be fixed on to position that birds easily nest and the top of insulator chain, when birds are stepped on or touch reflective plate, reflector sector-meeting rotates and birds is shied, birds cannot be nested herein, the support baseboard of bracing frame also can play and prevent that birds droppings from dropping to the effect on insulator chain, reduce the pollution level of birds droppings to insulator, improve the stable operation of transmission line of electricity, when wind wheel rotates, wind wheel can drive reflective plate to rotate, because birds fear the object of high light and motion, so it can shy birds around to walk.
The beneficial effect that the utility model brings is, effectively solve the difficult problem that birds cease and nest at shaft tower, the light of reflective plate reflection can be expelled birds, in the time that birds are dropped on reflective plate, reflective plate rotates the effect that also can play expulsion birds, birds are not injured, stop the generation of bird pest fault.To the person and birds without injury, cost is low, be suitable for large range promotion use, the utility model safety is light and handy, installs, dismounting (when upkeep operation) is convenient, solid and reliable, use material can meet antirust, anticorrosion and environmental requirement.
