Abstract

The utility model discloses a simple device for preventing birds from building a nest. The simple device comprises a semi-circular slipping mechanism arranged on the upper surface of a crossarm, and the slipping mechanism is connected with the crossarm in parallel. According to the simple device disclosed by the utility model, by fixing a PVC (polyvinyl chloride) pipe with an upward circular surface on the iron crossarm of a line through binding or other ways, as the upper surface of the PVC pipe is smooth, the birds can not stop on the PVC pipe and can not build the nest naturally, the occurrence of line trip power failure events caused by building of the nest by the birds can be effectively avoided, and the reliability in power supply can be improved.

Description

Simple and easy anti-bird is taken the nest device

Technical field

The utility model relates to power circuit auxiliary equipment technical field, relates in particular to a kind of simple and easy anti-bird and takes the nest device.

Background technology

Because human reinforcement to natural ecological environment protection consciousness; The procreation quantity of birds also increases gradually; Scope of activities enlarges day by day, and nearly 2 years statistics shows that the East China is because 220kV that the birds activity causes and above circuit relate to bird tripping operation 44 times; The line fault number of times is only second to damage to crops caused by thunder and outside destroy, occupied line fault sum the 3rd.Look at the main harm reason of birds to transmission line of electricity below: birds are nested: birds began on electric power line pole tower, to nest and laid eggs, hatch spring.Through site observation, be mostly birds such as magpie, crow, goshawk.The bird's nest that causes with branch; Though in the weather of drying, do not cause the accident; But chance rainy weather, the Bird's Nest on the shaft tower are blown to four winds and drop on live wire or outstanding bottle, branch contact wire (or near lead) ground fault that will be short-circuited; Like the nest of putting on the shelf at the cross-arm circuit, because of discharge ground connection even can cause and blow lead wire and earth wire or blow the cross-arm accident.Small bird is liked flight; And small bird likes mouth to hold thing flights such as branch, iron wire, faggot in the month; When their empty shuttle flights on the line; When thing such as iron wire, weeds drops on shaft tower cross-arm, the suspension insulator grading ring or when passing through, can cause line fault near shaft tower member and wire insulation gap; During tricky food small animal, small animal shorting stub pass plays the circuit ground tripping to bird on cross-arm; Flight possibly cause phase fault or singlephase earth fault when birds that build is bigger or birds fight between lead.Birds droppings is a kind of conduction mixing material, and water content and electrolyte are higher, between energized conductor, causes flashover; The second, fecal pollution the straight line suspension insulator, if stercoroma is too many, can make insulator generation pollution flashover accident; The 3rd; When birds be in insulator chain directly over when having loose bowels dung; Long rare dung can glide along porcelain patticoat surface, make to form a rare dung short circuit band on the insulator chain, causes insulator full skirt short circuit and creep distance is reduced; When 4 above insulator chains of rare dung short circuit, can cause the singlephase earth fault accident one time.

The utility model content

The purpose of the utility model provide a kind of simple in structure, easy to operate, change to be easy to simple and easy anti-bird and to take the nest device.

The utility model is taken nest, is influenced the Universal Problems of electric power safety to birds on the transmission line of electricity cross-arm; Designed technical scheme of the present invention: a kind of simple and easy anti-bird is taken the nest device; Comprise that the semicircle that is arranged on the cross-arm upper surface increases sliding mechanism, saidly increase the parallel connection of sliding mechanism with cross-arm.

It is the pvc pipe that cuts open to two halves that said semicircle increases sliding mechanism.

The utility model upwards bundlees through the disc with pvc pipe or other modes are fixed on the iron cross arm of circuit; Because it is slick and sly above the pvc pipe; Birds can't be stopped last; Nature can't be built nest in the above, can avoid effectively improving the reliability of power supply because birds are taken the generation that nest causes the line tripping power-off event.Use the technical scheme of the utility model to make a covering device, cost only needs about 5 yuan, and can reach 10 years service life, and preparation is simple, and is easy for installation, economical and practical.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the structural representation of the utility model.

Embodiment

Like Fig. 1, a kind of simple and easy anti-bird is taken the nest device, comprises that the semicircle that is arranged on cross-arm 1 upper surface increases sliding mechanism 2, saidly increases sliding mechanism 2 and cross-arm 1 parallel connection, and said cross-arm is arranged on the electric pole 3.Said semicircle increases sliding mechanism 2 for cuing open the pvc pipe into two halves.The utility model upwards bundlees through the disc with pvc pipe or other modes are fixed on the iron cross arm of circuit; Because it is slick and sly above the pvc pipe; Birds can't be stopped last; Nature can't be built nest in the above, can avoid effectively improving the reliability of power supply because birds are taken the generation that nest causes the line tripping power-off event.Use the technical scheme of the utility model to make a covering device, cost only needs about 5 yuan, and can reach 10 years service life, and preparation is simple, and is easy for installation, economical and practical.

Claims

1. a simple and easy anti-bird is taken the nest device, it is characterized in that: comprise that the semicircle that is arranged on the cross-arm upper surface increases sliding mechanism, saidly increase the parallel connection with cross-arm of sliding mechanism.

2. simple and easy anti-bird as claimed in claim 1 is taken the nest device, it is characterized in that: it is the pvc pipe that cuts open to two halves that said semicircle increases sliding mechanism.
