A rotating plate 5 is attached to the upper surface of the above so as to be connected to the built-in electric motor rotating shaft 4 in conformity with the axis of the column 2. Then, the rotary body 6 having a predetermined length formed by forming a piano wire into a rod shape having a required thickness is used.
The book is fixed so as to face the axis of the support column 2 and project from the peripheral end of the rotary plate 5. A raptor model body 7a, which also functions as a weight, is provided as a threatening member 7 at the tip of the rotating body 6, so that the rotating body 6 bends in a drooping shape when stationary and an arc when rotating. Furthermore, a plastic film, which is vapor-deposited with aluminum so as to reflect light and glitter, is hung as a threatening member 7 at various places on the rotating body 6 as a fluttering ribbon 7b.
In addition, install a permanent magnet as a repellent. Further, a microphone 8 that collects the sound of a harmful bird and a speaker 9 that generates a repellent sound are provided on the pillar 2 below the drive unit 3, and the photovoltaic power generation element 1 is provided between the microphone 8 and the speaker 9.
It is arranged so that 0 receives the sunlight conveniently.

いようにすることができる。The function of each part in the above structure will be sequentially described. Harmful birds such as sparrows, crows, and pigeons do not fly directly to Inada from a distance.First, nearby electric wires and fences,
Sometimes he stays at Sakashiko and is alert and intimidating. Then make a loud cry. When this squealing sound is caught by the microphone 8, the electric motor of the drive unit 3 is driven and the rotating body 6 fixed to the rotating plate 5 rotates. At the same time, the crowing and repellant sounds of the bird of prey on the voice board 15 reverberate from the speaker 9, and the rotating body 6 swirls together with the model bird 7a of the bird of prey and the ribbon 7b that flutters and scatters the light rays, and a positive recursive motion. I do. Then, due to the fear of hearing and the visual / instinctive fear / disgust of the object turning with the anti-bend motion, the harmful bird quickly dissipates. In addition, even when the solar radiation is weak in cloudy weather or the rotation of the rotating body 6 is weak, there is a positive inflexion motion, so that the irregular reflection of the light beam of the ribbon 7b is less decreased, and the movement of the reflective bird of prey model 7a is realistic. There is no possibility that a harmful bird will be used to stop on the rotating body 6. Further, since the driving unit 3 uses the electric motor, it is easy to make the rotation adjustment of the rotating body 6 irregular, and it is possible to prevent the harmful bird from getting used to it.

In the first embodiment, the rotating plate portion of the drive unit that houses the electric motor provided at the upper end of the support pillar in the first embodiment is the Saponius wind turbine 18, and the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. With this configuration, the electric motor becomes a generator when the rotation speed by wind reaches a predetermined value, and is stored in the storage battery together with the electric power from the photovoltaic power generation element 10. And when it is not charged but there is a rotating wind force, if a harmful bird comes in, only the wind force is used, and if the rotation by the wind force is insufficient, the electric motor that is also the generator is driven by the commercial power source and the storage battery power from natural energy. To do.

必要時に都度利用できるようにするのが効果的である。As described above, the electric power due to the natural energy fluctuates greatly. For example, harmful birds have a strong appetite in the early morning and before sunset, and during this time, the crops easily suffer from eating damage. However, since the sunlight is weak and the wind is weak during this time, the amount of power generation is small. Therefore, a storage battery is installed to accumulate surplus power from wind power that can be generated even when the sunlight is strong during the blue sun or at night.
It is effective to make it available whenever necessary.

The flexible long rod-shaped rotating body is made into a solid rod shape and is rotatably suspended from the upper end portion of the column with a thread-like material. Omit it. That is, the bird damage prevention device 19 is located at a required height above the surface of the earth on the lower outer periphery of the columnar pillar 20 that is erected.
A cylindrical rotating wheel 21 is rotatably mounted, and a belt is driven by an electric motor 22 externally attached to the column 20. The pillar 20 is vertically installed by burying the lower end where it is needed, and a branch line 20a is stretched from the upper end to the ground surface and fixed by an anchor 20b. Two rod-shaped rotating bodies 23 each having a predetermined length are provided on the outer circumference of the rotating wheel 21,
The support 20 is fixed so as to be opposed to the axial center of the support 20, and an auxiliary ring 24 is rotatably attached to the upper outer periphery of the support 19, and the tip of the rotor 23 is thin and strong like a fishing line. It is connected by a suspension line 25 and held horizontally. In this way, since the rotating body 23 is held at both ends by the rotating wheel 21 and the suspension wire 25, the rotating body 23 can be made considerably long. Therefore, the support column 20 is also reinforced by extending the branch line 20a. And the rotator 23 has a raptor model body 7 as a threatening member 7.

Even so, when the harmful bird approaches the rotating body 23 to come close to it, it comes into contact with the slender line 25, which is thin and difficult to see, and once the foreign body comes into contact with the body, the harmful bird never approaches again. Further, since the rotating body 23 can be made considerably long, the rotating body 23 can exert its effect over a wide range.

In the first embodiment, the connection of the rotating body protruding to the outer periphery of the rotating wheel can be moved up and down, and the shape material of the suspension wire for connecting the protruding tip end to the upper end of the support has elasticity. The same parts as 2 and 3 are denoted by the same reference numerals and the description thereof will be omitted. That is, the bird damage prevention device 26 includes the electric motor 2 that is rotatably mounted on the lower outer periphery of the standing columnar column 20.
Two rod-shaped rotating bodies 28 of a predetermined length are provided on the outer periphery of a cylindrical rotating wheel 27 which is belt-driven by 1, and are connected so as to be movable up and down in a hinge-like manner so as to protrude toward the axis of the support column 20. Prop 19
The upper auxiliary ring 24 and the tip of the rotary body 28 are connected by a suspension wire 29 of a tension coil spring and held horizontally.
