Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes use of the undulations of birds, such as crows, pigeons, and barn birds, to fly in large numbers and become a source of fecal damage and various pathogens. The present invention relates to a device for driving out harmful birds.

[0002]

2. Description of the Related Art In a building, an apartment, a station, a factory, and the like, a bird flying prevention device using a magnet to prevent pigeon dropping has been conventionally employed. In fact, the applicant of the present application has disclosed a bird flying prevention device in which a sphere is supported on an upright shaft rod, and a magnet that forms a magnetic field in the normal direction is provided on the surface of the sphere (Japanese Utility Model Application Laid-Open No. HEI 4-104). 129789).
In this device, an abnormal magnetic field which is disliked by birds is formed to repel birds, and further, wind wings are provided to rotate the sphere so that the magnetic field is spread over a wide range.

[0003] On the other hand, birds can sense waves different from humans, and can sense, for example, the ultrasonic range by hearing. However, birds dislike ultrasound. In view of the above, an object of the present invention is to disclose a bird flight prevention device that can be used in a wide range by utilizing the above-described wave motion that cannot be sensed by humans and repelled by birds as means for preventing bird flight.

[0004]

According to the present invention, in order to achieve the above object, in a bird flying prevention device, a sphere is supported on an upright shaft, and the sphere generates a wave which repels birds. , A solar cell for driving the wave transmitting device, and a wind vane for rotating the sphere are employed. Adopting such a means makes it possible to abolish birds without using a magnetic force as in the related art. In particular, means for generating an ultrasonic wave from the wave transmitting device as a wave motion that birds avoid is adopted. In addition, since a solar cell is used to drive the wave transmitting device, private power generation is possible and the device can be used in places where electricity is not conducted, which is convenient for the user.

[0005] Further, when the device is installed above a building or the like, which is a target for preventing birds from flying, the wave transmitting device transmits a wave obliquely downward of a sphere.

In order to intimidate birds such as pigeons from a visual point of view, means for connecting a pseudo bird feather to the wind feather is employed.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example of a bird flying prevention device disclosed in the present invention, in which a shaft 2 has a spherical body 2.
Further, on the surface of the spherical body 2, a wave transmitting device 3, a wind blade 4 and an absorbing plate 5 of a solar cell are provided. A characteristic configuration of the present embodiment is that a wave transmitting device 3 and a solar cell device for generating a wave aversion of birds to a sphere are provided. It is driven by in-house power generation. And the wave from the wave transmitting device gives a strong stimulus to the audiovisual nerves of birds, and the device has an effect of preventing birds from flying over a wide range.

FIG. 2 shows the inside of the birds flying prevention device, wherein 6 denotes an internal device of the solar cell, and 7 denotes a wiring portion of the solar cell. Note that the wind blade 4 is omitted in FIG. The solar cell absorbs sunlight with the absorbing plate 5 and becomes energy for driving the wave transmitting device via the wiring portion 7 and the internal device 6. When a solar cell is used, the wave transmitting device can be driven without using other power energy, and thus can be mounted even without a power supply device. Further, a charging device may be provided so that it can be used even at night or in bad weather. If necessary, a plurality of solar cells can be provided in series to increase the corresponding voltage of the device. In addition, the absorption plate 5 of the solar cell is
It is advisable to lay it on the upper half surface of the sphere, which has good sunlight absorption. Since the absorbing plate 5 can be provided on the spherical surface as described above, there is an advantage that the flying device itself does not become larger than the conventional one even when the solar cell device is employed.

The wave generated by the wave transmitting device is not particularly limited as long as it is aversion to birds and cannot be sensed by human audiovisual detection. Adopting such a wave is convenient because it does not cause discomfort to humans and can prevent birds from flying. For example, in the auditory region, it is an ultrasonic wave transmitted from an ultrasonic speaker, and in the visual region, it is an infrared ray transmitted from an infrared radiator. Although a method of preventing birds from flying by using sound waves has been conventionally used, most of the methods include a human audible range and often cause driving noise or are unpleasant sounds. The present invention avoids this point by using ultrasonic waves, and is very useful when used in places where people enter and exit frequently.

[0010] Even if the sound is audible to humans, it can be adopted in the present invention as long as it is not a sound wave that is unpleasant for humans but a sound that is aversion to birds. Further, it is also possible to use the above-mentioned audible sound and ultrasonic waves together. As a method of using both of them, a wave transmitting device may be separately provided for one sphere, or a device that generates these waves randomly from one wave transmitting device may be adopted. On the other hand, a wave transmitting device that can be arbitrarily changed even in the ultrasonic band may be adopted. Adopting these can avoid getting used to birds. Waves are not limited to sound waves, and light waves that birds can visually sense, and light waves that humans cannot sense also apply to the present invention.

By the way, the power of the wave extends around the sphere along the rotation trajectory of the wave device because the wave device rotates with the sphere on which the wave device is mounted. In particular, in the embodiment shown in FIG. 1, the wave device is provided obliquely downward from the sphere. This device protects buildings and the like, and is often installed on these buildings. It was done. Of course, the number of wave devices is not limited to one, and a plurality of wave devices may be provided as necessary. Providing a plurality of wave devices on the same rotating orbit enhances the effect on the orbit. On the other hand, when provided on different rotating orbits, the effect is exerted over a wide range from the spherical surface. In this case, it is most effective to provide them at different positions in both circumstances.

The wind vane 4 serves to rotate the sphere 2 and adapt the effect of the wave motion to a wide range. However, the wind vane and the solar cell, that is, a place where the wind or sunlight cannot be used, for example, For indoor use such as inside factories and station buildings where wind is not always available or where sunlight is blocked, a motor may be used instead. Of course, both may be used in combination, and the configuration may be such that the motor is operated by the storage battery only at night or when there is no wind.

FIG. 3 shows a configuration in which a simulated bird blade 8 is further connected to the wind blade 4 of the above-mentioned flying prevention device. The simulated bird feather simulates the arrival of a large bird such as an eagle or a hawk by floating in the air or flying horizontally with the rotation of the sphere. By giving the impression that such a large bird is flying, it is possible to visually threaten the arrival of small birds such as pigeons. As a result, the repelling effect by the wave and the threatening effect by the pseudo feather are combined, and a more powerful bird-flying prevention effect is obtained. In addition, a conventionally used magnet may be provided on the sphere.

In order to prevent damage or deformation even in strong winds or gusts, the spheres are made of weather-resistant reinforced plastic and the shaft is made of SUS steel with a single diameter. With such a configuration, the bird flight prevention device is approximately 40 m
/ S wind force. In addition, all rotating parts are equipped with sealed bearings to withstand long-term rotation. The size of the sphere or shaft is not particularly specified,
The user can appropriately set according to the target and the use environment. To give an example, the diameter of the sphere is 10 to 30c.
When the maximum diameter of the wind vane is about 10 to 50 cm, the effect can be exhibited in a wide range without any obstacle.

The flying prevention device disclosed in the present invention is:
It is preferably provided on a high-rise building, an air-conditioning facility, an elevated water tank, a stage of a power transmission tower or a wireless communication tower, a marine buoy, a lighthouse facility, various facilities at an airport, near overhead lines, various facilities such as a dome, a bullet train, and the like. In this case, it is particularly effective in preventing fecal damage and mischief. Further, it may be provided in a farm, an orchard, a farm for shellfish, seaweed, or the like and used to prevent food damage.

[0016]

According to the birds fly prevention device disclosed in the present invention, the wave transmitting device is provided on the surface of the sphere, thereby stimulating the audiovisual nerves of the birds and eliminating the use of the conventionally used magnet. In addition, it has become possible to prevent birds from flying over a wide area. In particular, by employing ultrasonic waves that are not in the audible range of humans, it has become possible to avoid birds without causing discomfort to humans.

Further, by providing a solar cell, the wave transmitting device can be driven without using other energy, and can be easily installed even in a place where electricity is not conducted. In addition, the absorption plate of the solar cell can be provided on the surface of the sphere, so that the device can be maintained at almost the same level as in the past.

Further, since the wind vane rotates the sphere, the wave transmitting device provided on the surface of the sphere also rotates with the rotation of the sphere, so that the effect of the wave reaches the entire rotation orbit. In particular, by providing the wave transmitting device so as to transmit the wave obliquely downward of the sphere, the effect can be more effectively exerted in the direction of the building or the like in which the device is installed, and remarkable birds The flying prevention effect was obtained. On the other hand, the use of a plurality of wave devices has effects in various fields and can cover a very wide range. Further, since the pseudo bird feather provided on the wind feather rotates, the small bird reminds of the arrival of a large bird. Thus, combined with the repelling effect by the wave motion, a composite flying prevention effect is obtained.
