TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird flying prevention device for preventing birds such as pigeons and crows from flying and approaching houses, factories, fields, and the like, and preventing damage by these birds.
[0002]
[Prior art]
Conventionally, sparrows and crows in paddy fields and fields and the like, and fecal damage in houses and factories have been problematic. In particular, bird feces not only stains the roof and veranda, but also transmits various pathogens, and scattered fine powder of dried feces causes respiratory diseases. In order to avoid the approach of these birds and prevent various harms, various bird flying prevention devices have been proposed.
[0003]
For example, there are those that use dolls imitating human figures or natural enemies such as eagle and hawk, those that emit voices and explosions intermittently, and those that emit light, ultrasonic waves, and magnetism that birds avoid.
[0004]
These use a doll such as a human or an eagle to threaten or repel birds by utilizing the fact that birds do not approach natural enemies. In addition, the birds are surprised by voices and explosions to prevent them from approaching. In addition, birds feel threats and repel light and ultrasonic waves, and fluctuate the body magnets due to the fluctuating magnetic field.
[0005]
[Problems to be solved by the invention]
However, among these, the dolls and sounds have a problem that the birds become accustomed to their shapes and sounds over time, and the bird following effect is reduced. In addition, in order to obtain an effect over a wide range, an apparatus using an ultrasonic wave or a magnet requires a relatively large device and requires a large cost.
[0006]
Under such circumstances, the present inventor pays attention to the property that birds are sensitive to instantaneous light emission and repels them, and provides an inexpensive device that repels birds over a wide range by instantaneous light emission. It is intended for that purpose.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention employs a means in which a windmill is formed by a plurality of blades, rotatably supported on a support shaft, and a light emitter that emits light instantaneously is attached to the blades.
[0008]
In this case, a luminous body may be attached to each blade plate, or a plurality of luminous bodies may be attached to one blade plate.
[0009]
In any case, since the luminous body emits light instantaneously while rotating, birds can avoid the light and prevent the light from flying.
[0010]
In addition, a means for further attaching a magnet to each blade plate was adopted.
[0011]
An abnormally fluctuating magnetic field is formed by the rotating magnet, and this magnetic field disturbs the bird's internal magnet and repels it.
[0012]
In addition, a means is adopted in which the support shaft is rotatably supported by a support rod.
[0013]
Since the support shaft for supporting the rotating windmill is further rotatably supported by the support rod, light is emitted over the entire circumference of the support rod, and a repelling effect can be exerted over a wide range.
[0014]
In addition, a means for attaching a power generation unit including a power generator and a control circuit to the support shaft and generating light by rotating the windmill to emit light from the luminous body is adopted.
[0015]
Since the luminous body is caused to emit light instantaneously by the electric power generated in-house by wind power, energy saving can be achieved and the present apparatus can be provided at low cost.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of a bird flight prevention device according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of the present apparatus, and FIG. 2 is a side view.
[0017]
In each of the figures, reference numeral 1 denotes a wind turbine composed of a plurality (five in the figure) of blade plates 1a, 1a,... Made of a synthetic resin having excellent weather resistance and light weight. It is rotatably supported via a. The wind turbine 1 is formed so that each blade plate 1a is bent so as to be easily rotated even by a slight wind. Reference numerals 4, 4,... Denote light emitters mounted on the respective blades 1a of the wind turbine 1 toward the front, and are composed of, for example, high-brightness LEDs, strobe bulbs, etc., and emit intense, straight-forward light instantaneously. Things. Each light emitting body 4 is attached at a position different from the center so as to draw a concentric circle when the windmill rotates. The instantaneous light emission of the light emitter 4 stimulates the optic nerves of birds, and has an effect of keeping birds away. For example, when a high-brightness LED is used, the light emission sensing distance is about 20 to 30 m. Reference numeral 5 denotes a film-like cable wired in accordance with the curved shape of the blades to supply a current to the light-emitting bodies 4, and connects each light-emitting body 4 to a power generation unit 7 described below.
[0018]
Reference numeral 6 denotes a magnet mounted near the tip of each blade plate, which forms an abnormally fluctuating magnetic field by rotation of the windmill. The birds disturb and repel the biomagnets.
[0019]
Reference numeral 7 denotes a power generation unit provided at the tip of the support shaft 2, comprising a power generator 7 a and a control circuit 7 b. The power generator 7 a generates power in accordance with the rotation of the wind turbine 1 and supplies current to each light emitter 4. . The light emitting elements 4 are intermittently and simultaneously emitted at appropriate intervals by the control circuit 7b. The light emitting intervals and the mutual light emission of the respective light emitting elements 4 are set by the control circuit 7b. Can be set arbitrarily.
[0020]
Reference numeral 8 denotes a support rod which supports the support shaft 2 to which the wind turbine 1 is attached so as to be swingable about the vertical axis. Therefore, the present device can freely change the direction according to the wind direction. The device is installed at a desired place such as the ground, a roof, a veranda, etc. via the support rod 8.
[0021]
In the above-described embodiment, the number of blades of the wind turbine is set to five, and the wind is received in a torsion shape supported at two positions in front and behind the support shaft. However, the present invention is not limited to this. The shape and the number are not particularly limited as long as it is a windmill shaped to rotate.
[0022]
Further, in the above-described embodiment, an example in which one luminous body 4 is attached to each blade plate 1a is exemplified. However, the present invention is not limited to this, and a plurality of (for example, 5, 6) ) Light-emitting bodies 4 may be attached. Also in this case, the luminous body 4 draws concentric circles as the windmill 1 rotates, so that the effect of repelling birds is the same as in the above embodiment. Further, in this case, since the wiring of the cable 5 needs only one blade plate, the manufacturing cost can be reduced.
[0023]
Furthermore, in each of the above embodiments, if the color of the light emitting body 4 is set to a plurality of colors such as white and red, and the colors are alternately emitted, the repelling effect of birds is increased. In this case, if the light emission timing of each light emitter is made to emit light irregularly, birds are prevented from getting used to light emission, and the repellent effect is maintained for a long time.
[0024]
【The invention's effect】
As described above, since the birds flying prevention device according to the present invention has a powerful luminous body that emits light intermittently on the blades of a rotating windmill, birds are threatened and dazzled by the instantaneous light emission. And can surely avoid birds. In particular, since the luminous body rotates concentrically around the support shaft and swings and swings with the support rod, instantaneous light emission is emitted over the entire circumference around this device, and the bird's repelling effect is widespread Excellent effect can be expected.
[0025]
In addition, since a magnet is attached to each wing plate, an abnormally fluctuating magnetic field is formed around the windmill by rotating, and the internal magnet of birds is disturbed. The combined effect results in a greater repellent effect.
[0026]
Furthermore, since the luminous body emits light by the current generated by the rotation of the windmill by natural wind power, it is environmentally friendly and can save energy, and does not require a separate power supply. Do not choose. Further, since the configuration is relatively simple, it is inexpensive and has excellent durability.
