The purpose of windmills on high-voltage poles is to repel birds.
The small windmills on the telephone poles are used to drive away birds and prevent wild birds from nesting on the poles and causing danger; most small windmills are also equipped with small mirrors, which can be used as small windmills. As it rotates, small mirrors on its blades reflect sunlight in all directions. To birds, the windmill acts like a rotating police light that emits a strong flashing signal.
Bird repelling is also called bird driving, bird prevention, bird collision prevention, etc. Broadly speaking, farms, orchards, wind power plants, military and civilian airports, etc. all prevent harmful birds from invading their own territory and thus endangering themselves. The results of labor or the means of ensuring equipment safety are called bird repellents.
In a narrow sense, bird repelling means specifically used at military and civilian airports to protect the safety of aircraft taking off and landing, and to prevent birds from being sucked into the aircraft engine or hitting the aircraft body, landing gear, tail, and windshield when the aircraft is taking off and landing at high speed. Glass and all aircraft fuselage.
Thus, all measures such as auditory intimidation, visual deterrence, direct killing, chemical, ecological or radar warnings are taken to prevent bird invasion in the key flight areas of the airport, especially the runways or taxiways where aircraft take off and land. means.
Bird repeller classification:
1. Stainless steel wind bird repeller (WMA-B).
The rotating wind bucket is made of high-quality stainless steel, which is corrosion-resistant, lightweight and easy to start with breeze. 360-degree reflection angle, no blind spots. It rotates fifteen to twenty times per minute, and the effect of repelling birds is obvious.
The wind bucket of this product is made in the shape of a windmill to auxiliary power and increase the power and speed of the bird repeller's rotation; the rotating shaft is designed with a damping coefficient, which has an anti-typhoon effect and will not rotate infinitely, which is safe. reliable. The base and the outside of the iron pole are coated with anti-corrosion galvanized coating for durability.
2. Ordinary (WMA-I/II)/double-layer insulated wind bird repeller (WMA-III).
Developed based on the characteristics of birds that are afraid of light and color, especially the fear of flashes. The impeller base, bearings, casing and reflector base of the product are all made of engineering plastic polyacetal. POM, the bearing itself has lubricating properties and does not require any additional lubricant.
The reflective mirror frame is designed in a bowl shape to auxiliary power and increase the power and speed of the bird repeller's rotation; the rapid rotation of the blades and the reflector in different directions can cause visual interference and frighten the birds. , to achieve the effect of repelling birds.

The windmills used in wind power generation are the reason for the three-page turn;
1. Three blades can improve the wind sweeping efficiency, and the three blades can also maintain the balance of the wind turbine.
2. The number of blades of the wind turbine is 3, which is the optimal result under the comprehensive consideration and action of many factors, mainly the optimization and balance between aerodynamic efficiency and structural complexity.balance.
3. The three-piece turning page determines the low manufacturing and maintenance costs and easy use.
