DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing birds such as pigeons from flying to prevent feces and other damages caused by the birds.

[0002]

2. Description of the Related Art Recently, a large number of pigeons inhabit in various places, especially in parks and shrines and temples. Pigeons are a symbol of peace and are loved by everyone because of their cuteness and are very popular with children. However, this pigeon also has some harmful parts. This pollutes various places with excreted feces and impairs aesthetic appearance, and also causes corrosion on metal parts because feces are acidic. It may also be a source of infection by various pathogenic bacteria (such as parrot disease). Besides, not only feces damage but also squeals in residential areas interfere with sleep and become harmful.

Various measures have been implemented as means for preventing this harmful pigeon from flying. This can be achieved by installing needles, nets, etc., to prevent the pigeons from flying directly, by installing false eyeballs, causing the pigeons to scare them away, or by using ultrasound with a wavelength that the pigeons do not like. Numerous ideas have been devised and put into practice, such as a method of generating a sound to prevent a pigeon from flying, a method of installing a substance that emits an odor that hates a pigeon, and a method of keeping it away. However,
None of these methods can provide an absolute effect.

[0004] Therefore, based on the theory that the homing of pigeons is related to the earth's magnetic field, a device has been devised to prevent the pigeons from flying by locally generating an abnormal magnetic field.
It has been implemented. Japanese Utility Model Laid-Open Publication No. 1-63386 describes an apparatus for preventing bird damage, for example, the S pole and the N pole of one magnet body.
It is intended to prevent birds by generating a fluctuating magnetic field by rotating using a natural wind around an intermediate portion of the poles. It is intended to prevent birds by generating a fluctuating magnetic field by rotating a motor around a pole intermediate portion. In addition,
In 108090 "Birdproof device using fluctuating magnetic field" and Japanese Utility Model Laid-Open No. 1-146881 "Dove flying prevention device", a magnet body is fixed to a tension string, and it is installed at a predetermined position, and the bird itself raises itself. By creating a fluctuating magnetic field by the wind, birds are to be protected. Next, 4-2
The 8080 "birds flying prevention device" is intended to prevent birds by generating a fluctuating magnetic field by rotating a plurality of magnet bodies attached to a propeller using wind.

Each of these methods also has advantages and disadvantages. That is, in the actual Kaihei 1-63386 "device for preventing bird damage", the movement of one magnet body is controlled, and the control method is also the method of the present application in which natural wind is used. When there is no, it does not function at all.
It is also an inefficient method of moving one magnet body with one motor. Moreover, the rotation of the magnet body is limited to the shape of the magnet body, and the range of the fluctuating magnetic field is very small. In Japanese Utility Model Laid-Open No. 1-108090 "Birdproofing device using fluctuating magnetic field" and Japanese Utility Model Laid-Open No. 1-146881 "Dove flying prevention device", the method of the present invention is to use the wind generated by the bird itself. Since the wind power is also small, its effect has not been fully demonstrated. In Japanese Utility Model Laid-Open No. 4-28080 "Bird flying prevention device", since the former two are one magnet body, a plurality of them are simultaneously moved, so that it can be said that the point is efficient. However, this is also a method of the present invention that utilizes the natural wind, does not function at all when there is no wind, and even if there is wind, the position of the fluctuating magnetic field depends on the wind direction, and it is one-sided, It is only a part of the effect in a certain direction and cannot be said to be fully effective.

[0006]

In view of the above, the means for oscillating the magnet in the present application to cause a magnetic field fluctuation due to other force such as wind is unstable and cannot be said to always operate effectively.
In addition, automating each of the plurality of magnets by driving a motor not only complicates the apparatus but also is very uneconomical. The present invention is intended to solve such problems by the following points.

[0007]

SUMMARY OF THE INVENTION In the present invention, the above-mentioned problems are solved by a main magnet device having a magnet which is rotated by driving a motor and a plurality of sub magnet devices having a magnet which is rotated about a free rotating shaft. And at least one of the magnets of the subordinate magnet device is arranged at an interval that rotates in synchronization with the rotation of the magnet of the main magnet device about the free rotation axis, and the magnets of other subordinate magnet devices are subordinate to each other. The problem is solved by providing a magnet rotation tuning type bird flying prevention device installed side by side at an interval of rotating in synchronization with the rotation of the magnet.

[0008]

The plurality of magnets have a property of adsorbing or repelling each other within a certain distance depending on the magnetizing direction and interfering with each other. The present invention takes advantage of this property, and when the magnet of the main magnet device including the magnet that rotates axially by the drive of the motor rotates, the magnet of at least one sub magnet device is synchronously rotated, and the sub magnet is rotated. When the main magnet device and the plurality of subordinate magnet devices are installed side by side at intervals such that the rotation of the magnets of the device sequentially rotates the magnets of the other subordinate magnet devices, the rotation of the magnets of the main magnet device is sequentially Is transmitted to the magnet of the subordinate magnet device.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows the principle of synchronous rotation of the magnet due to in-plane rotation. Four magnets 1a, 1b, 1c,
1d is arranged so as to rotate in the same plane with each center as an axis. In this figure, the magnet 1
When a is rotated as indicated by the arrow, the magnets 1b, 1c, 1d rotate in synchronization as indicated by the arrow.

FIG. 2 shows an embodiment in which a main flying magnet device and a plurality of secondary magnet devices are attached to a lower mounting base material in a bird flying prevention device. The main magnet device 1 is axially coupled to a motor shaft 5 of a motor 4 so that a magnet 3a rotates in the same plane by axial rotation, and is attached to a mounting base material A by a bolt 7 via a mounting portion 6. Each of the plurality of subordinate magnet devices 2 is equipped with the magnet 3b so that the magnet 3b can freely rotate on the free rotation shaft 8 and rotates in the same plane. It is attached to the base material A. Reference numeral 10 is a holding portion that holds the magnet 3b so that it does not fall downward because the magnet 3b freely rotates with respect to the free rotation shaft 8.

The distance between the main magnet device 1 and the sub magnet device 2 is such that when the magnet 3a of the main magnet device 1 rotates.
The distance that the magnet 3b of the subordinate magnet device 2 is tuned and rotated. The distance between the subordinate magnet device 2 and the subordinate magnet device 2 is also one when the magnet 3b of one subordinate magnet device 2 rotates,
The distance by which the magnet 3b of the other subordinate magnet device 2 rotates in synchronization. By the way, the distance between the magnets 3a and 3b is φ10 mm.
When a magnet of × 50 mm is used, it is about 100 mm.

The magnet rotation tuning type bird flying prevention device thus constructed operates as follows. When the magnet 3a of the main magnet device 1 is rotated by the drive of the motor 4, the magnet 3b of the secondary magnet device 2 is rotated by the free rotation shaft 8
Rotate synchronously around. Then, this rotation further causes the magnet 3b of the adjacent magnet device 2 to rotate in synchronization.

[0013]

The present invention has the following effects because it is constructed as described above.

When the magnet of the primary magnet system rotates, at least one of the magnets of the secondary magnet system rotates synchronously,
The rotation of the magnet of the subordinate magnet device is sequentially arranged by arranging the main magnet device and the plurality of subordinate magnet devices side by side at an interval at which the magnets of the other subordinate magnet devices are synchronously rotated. , Sequentially transmitted to the magnets of the plurality of subordinate magnet devices.

Therefore, among the magnets of the plurality of magnet devices to be installed, the magnet of the main magnet device is rotated by driving the motor, and the magnets of the other subordinate magnet devices are synchronously rotated to generate the fluctuating magnetic field. Therefore, unlike rotating a plurality of magnets by a motor, the device is not complicated and is economically advantageous. Further, since the magnet device itself is independent, it can be arbitrarily arranged depending on the situation of the site.
