Background

Some birds eat fruits on fruit trees or buds on crops, resulting in reduced yields of fruit trees or crops. Especially for large-area planting areas such as orchards or farms, large economic losses can be caused. But also bird droppings can be left on fruits or crops on the fruit trees to pollute the fruits or crops. It is therefore necessary to install bird repellers in an orchard or farm. Bird repellers scare birds by making sounds, lights and movements. The existing bird repeller comprises a manual type and an electric type, and the electric type can be powered by a battery, a solar battery or a power plug. The manual bird repeller has low efficiency and small application range. The electric bird repeller can continuously work for 24 hours, so that the electric bird repeller has good bird repelling effect. But the electric bird repeller is limited in use by the covered area of the power grid. While for people living in mountainous areas, most fruit trees or crops are planted on the reclaimed mountains. And because the mountain land topography is complicated, the electric network coverage degree is less even does not have electric network coverage, so plant orchard or crops on the mountain land, be inconvenient for adopting electric bird repellent to drive the bird.

The utility model provides a bird repellent device which can drive birds by wind power by using sufficient wind power in mountains as driving force through being provided with wind power driving fan blades. Through setting up arm of force adjusting part, can adjust the driving force arm of wind-force drive flabellum according to wind-force size, can adapt to the wind-force in different seasons all the year round. And the bird repeller is not excessively worn, so that the service life of the bird repeller is prolonged.
