What's the use of installing windmills on telephone poles?

Used to drive away birds.

According to the query of Baidu Library, the windmill on the fairy waste is used to drive away birds. In order to prevent the construction of desert islands on electric waste, most small windmills are also equipped with small mirrors. When small windmills rotate, small mirrors on their blades can reflect sunlight in all directions. For birds, a small windmill is like a rotating warning light, which can send out a strong flashing signal.

Bird repellent is also called bird repellent, bird prevention, bird collision prevention, etc. Broadly speaking, farms, orchards, wind power plants, military and civilian airports and all other means to prevent harmful birds from invading their own territory, thus endangering the safety of their labor achievements or equipment, are called bird repellent. In a narrow sense, bird repelling refers to military and civil airports. In order to protect the safety of aircraft take-off and landing, and to prevent birds from being sucked into the aircraft engine or hitting all aircraft bodies such as the aircraft body, landing gear, tail wing and windshield during high-speed take-off and landing, all measures such as auditory intimidation, visual shock, direct killing, chemical, ecological or radar warning are taken to prevent birds from entering the key flight areas of the airport, especially the runway or taxiway where aircraft take off and land.
