Description
Technical field
The scarer installed in a kind of tower bar is the utility model is related to, is specifically to be related to one kind to utilize wind-force
The pneumatic type rotation bird-scaring unit of driving rotation, belongs to the safe ancillary technique field of power transmission.
Background technology
In recent years, as technological progress and development cost gradually reduce, to meet that new energy concentrates large-scale development and complete
State's consumption needs, and China accelerates the construction speed of power network.But in these years, with the improvement of ecological environment, the procreation of birds
Speed increases year by year, is influenceed by human lives, it is necessary to birds are all liked nesting on the shaft tower in ultra-high-tension power transmission line in the procreation phase,
These birds are when nesting, the conductive materials such as the withered rattan of branch and iron wire due to being often mingled with moistening in Bird's Nest, and birds
The insulator that a large amount of excrement of discharge are also easily installed on pollution shaft tower very much, therefore easily cause line-to-ground or short circuit occurs
Trip accident, serious threat the safe operation of power network.At present, in order on the premise of birds are not injured ensure circuit it is normal
Operation, power department mainly installs various scarers for bird pest on high voltage transmission line tower, to avoid birds in high voltage transmission line tower
It is upper to stop, nest.
Scarer common at present is that bird repellent thorn, this bird repellent is fixedly mounted in the key position installed on high voltage transmission line tower
Thorn is that a branch of spring draw point is fixed on base, and the upper end of spring draw point is outwards scattered in corolla shape, passes through the point of spring draw point
Thorn realizes bird repellent, and the concrete structure of this bird repellent thorn can be referring to Chinese utility model patent open file CN201204417Y, this
Kind of bird repellent thorn use fixed installation mode, simple in construction, cost is relatively low, and effect on driving birds is preferable when initially installing, but the time one is grown
Many birds just no longer fear, can still pierce at bottom gap and nest in bird repellent, the effect of bird repellent can be worse and worse with time lengthening.
Chinese utility model patent open file provides a kind of autonomous rotary bird repellent thorn, and it is to be arranged on draw point beam by rotating shaft
On base, motor is connected in rotating shaft, uses battery and solar panel to be powered for motor, drive needle Shu Xuanzhuan strengthens
The effect of bird repellent.But for being arranged on the high voltage transmission line tower in mountain forest field, exposed to the weather influences for a long time, its sun installed
Can cell panel be difficult to battery stable power supply be provided, and the bearing assembled in the motor of its installation and rotating shaft also easily by
The influence of adverse circumstances and break down, its work steady in a long-term can not be ensured.
Utility model content
The purpose of this utility model is：A kind of pneumatic type simple in construction, being capable of long-term stable operation in the wild is provided
Rotate bird-scaring unit.
The technical solution adopted in the utility model is as follows：A kind of pneumatic type rotates bird-scaring unit, including base, is rotatably installed in
Rotating shaft on base and the draw point beam being fixed at the top of rotating shaft, offer mounting hole, the mounting hole site vertically on the base
It is stepped hole in the aperture of base top, the axis of rotation is plugged in mounting hole and insertion step is fixed with the rotating shaft
Land in hole, left between the outer rim and stepped hole inwall of land gap and land bottom surface and stepped hole step surface it is mutual
Parallel, circumference is laid with some permanent magnets respectively on the land bottom surface and step surface, the land bottom surface fix it is each forever
The pole orientation and magnetic induction intensity of magnet are identical, and the pole orientation of fixed each permanent magnet and magnetic induction are strong on the step surface
Spend the pole orientation and the pole orientation phase of each permanent magnet set on the step surface of identical each permanent magnet in the land
Instead, the upper end of the rotating shaft is higher by base and passes through two radially fixed setting with upper connecting rod even circumferential in rotating shaft upper end
There is driving wind bowl.
Described land bottom surface and groove floor are up big and down small frustum of a cone table top.
Described permanent magnet is tile-type permanent magnet, and the magnetic pole of each tile-type permanent magnet is divided into its inner concave or arcuate surface
On.
On the base dust cover is installed at the aperture of stepped hole.
The hole of getting out of a predicament or an embarrassing situation with the mounting hole coaxial communication is offered upward in the bottom surface of the base, in the rotating shaft
Bottom be fixed with and get out of a predicament or an embarrassing situation hole step surface block coordinate limiting plate.
Pneumatic type rotation bird-scaring unit of the present utility model is the land and step between rotating shaft and base by being engaged
The opposite permanent magnet of hole installation pole orientation, causes rotating shaft to be arranged on base in suspended state using the principle that identical charges repel each other
On, the frictional force that is effectively reduced between rotating shaft and base also can be operated normally even in bad weather, so as to
Easily bird repellent thorn is promoted to rotate for a long time by wind bowl using the wind-force of nature, its overall structure is simple, the side of installing and using
Just, solve the problems, such as that prior art is present.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model pneumatic type rotation bird-scaring unit.
