Abstract
The utility model discloses it is a kind of can anti-bird pest arc extinguishing lightning protection device, the lightning protection device main body (1) including being fixedly mounted on cross-arm or insulator chain upper end by connection gold utensil, at the top of lightning protection device main body (1) equipped with bird-resistant；The bird-resistant is mainly made of bolt (2), nut (3) and thorn item (4)；The lightning protection device main body (1) is equipped with the internal thread hole being adapted with bolt (2)；One end of bolt (2) is threaded togather with lightning protection device main body (1), and the other end is connected with nut (3)；The bottom of the thorn item (4) is fixedly mounted on nut (3).The utility model is installed in parallel beside the insulator chain of transmission line of electricity, and is provided with bird-resistant, and the phenomenon that birds nest on insulator chain or lightning protection device, reduce line fault caused by nesting because of birds to greatest extent can be effectively prevented.
Description
Technical field
The utility model belongs to thunder resisting equipment technical field, and in particular to it is a kind of can anti-bird pest arc extinguishing lightning protection device.
Background technique
From security consideration, overhead transmission line operates in deserted mountain field, broad covered area, variation of ecology and environment mostly at present
It is variable.Gradually improve however as ecological environment, birds quantity gradually increases, and also gets in the activity of electric power line pole tower attachment
Come more frequent.Many birds selections are built above power overhead network line pole tower porcelain vase string or lightning protection device nests, and birds utilize
The objects such as branch, iron wire faggot, square shuttle flight on the line, or when meeting strong wind weather, the objects such as iron wire fall in cross-arm and lead
Between line, will cause line fault, birds droppings can also pollute porcelain vase string, encounter there was dampness in the air, foggy weather when flashover easily occurs, it is right
Line security operation, which causes, to be seriously threatened.To since bird collides overhead transmission line, manure contamination insulator and constructs
Transmission line short-circuit fault caused by Bird's Nest had become after damage to crops caused by thunder and external force broken outer an important factor for causing line tripping later, had
Effect prevention and treatment bird pest has become defeated
The key of electric line safe and stable operation.And existing scarer has plenty of using special in outside of deivce face smearing
Determine color flush, but birds are adaptable, staticizer can be adapted in a short time, so this scarer can not be held
It is continuous to play the role of bird repellent；Some scarers by play birds natural enemy pipe or birds wail sound make birds generate fear
Fear and flees from.But the scarer has very big regional limitation, the using effect difference of different regions is larger, is not suitable for big
Range is promoted, and this device is easy to produce noise pollution in residential area, has an impact to resident's normal life.Therefore, city
Be badly in need of on field it is a kind of it is effective, lasting effect is long, scarer without geographical restrictions, applied widely.
Utility model content
The purpose of this utility model is that be directed to the deficiencies in the prior art, provide that a kind of structure is simple, design
Rationally, it is stable and reliable in work can anti-bird pest arc extinguishing lightning protection device.
To achieve the goals above, the utility model uses following technical scheme:
It is a kind of can anti-bird pest arc extinguishing lightning protection device, including be fixedly mounted on cross-arm by connection gold utensil or insulator chain
The lightning protection device main body of upper end is equipped with bird-resistant at the top of lightning protection device main body；The bird-resistant is mainly by bolt, nut
It is constituted with thorn item；The lightning protection device main body is equipped with the internal thread hole being adapted with bolt；One end of bolt and lightning protection device
Main body screw links together, and the other end is connected with nut；The bottom of the thorn item is fixedly mounted on nut.
The utility model is installed in parallel beside the insulator chain of transmission line of electricity, and bird-resistant is provided at the top of device, can
To effectively prevent birds to nest on insulator chain or lightning protection device, reduce to greatest extent because birds nest cause route therefore
The phenomenon that barrier；Meanwhile lightning protection device can also carry out arc extinguishing to the arc flash that lightning stroke generates, and guarantee the normal steady of transmission line of electricity
Fixed operation.
It further illustrates, the bottom of the thorn item is welded on nut and in the shape that scatters.Scatter shape thorn item not only
It can cover above lightning protection device, the top of insulator chain can also be covered, it is ensured that birds are in lightning protection device and insulator chain
Top can not nest.
It further illustrates, the thorn item is the needle-shaped steel wire of stainless steel material.Using stainless steel material, anti-bird can be prevented
Corrosion in harsh environment is pierced, maintenance cost is reduced.
It further illustrates, the thorn top is thin, bottom end is thick.
In the present invention, lightning protection device main body is mainly to use the structure of the lightning protection arc-control device of previous design, such as
Chinese Patent Application No. is 2015100691235,201510069029X, 2015100690105 etc., naturally it is also possible to be used
Other lightning protection structures in the prior art.
It is that the utility model has the utility model has the advantages that
1. the utility model simple structure and reasonable design, maintenance cost is low, can effectively administer bird pest problem.
2. the lightning protection device main body in the utility model and being all made of threaded connection side between bolt, between screw bolt and nut
Formula, not only stable connection, but also the component accordingly damaged convenient for later maintenance, replacement.
3. several thorn items of the utility model setting are in scattering shape, wide coverage, at the same cover insulator chain with
The top of lightning protection device main body effectively prevents birds nest building behavior on insulator chain or lightning protection device main body.
