However, in the conventional systems, there is a problem that the harmful birds become accustomed to the stimulation and the repulsion effect is weakened after a while after installation.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an apparatus for repelling a harmful bird that can reliably prevent damage to birds and animals for a long period of time.

[0006]

Accordingly, a repelling device for a harmful bird according to the present invention is a repelling device for repelling a harmful bird or animal from a desired area. A bird and beast detecting means for detecting that a harmful bird or animal approaches the area to be evacuated or enters the area to be repelled, and receives a signal from the bird or beast detecting means to control the stimulating means so that the harmful bird or animal is alerted. Or a control means for intermittently and repeatedly generating a repellent stimulus.

One of the features of the present invention is that when a harmful bird approaches a region to be repelled or when a harmful bird enters the region to be repelled, a stimulus to watch or repel the harmful bird is generated intermittently and repeatedly. It is in the point which was made. As a result, the harmful birds and animals are intermittently and repeatedly alerted or repelled by stimuli, and are surprised by the illusion that there is a human or other animal, for example, a natural enemy. It is possible to secure the effect of repelling harmful birds and animals for a long time.

[0008] Also, since the harmful birds and animals vigilantly or repelling stimuli are intermittently and repeatedly generated, not only doves and chicks but also crows and other birds, dogs, cats, monkeys, wild boars, etc. are expected to have a repelling effect. .

The control means may be constituted by using a CPU or the like in which program software is stored, but is preferably constituted by using a hardware circuit in terms of cost. That is, the control means includes: a start signal generating means for generating a start signal in response to a signal from the bird and beast detecting means; a timer unit for generating an operation time signal in response to the start signal; Operation control means for intermittently and repeatedly operating the means.

In this case, a photosensor can be used as the starting signal generating means as shown in the following embodiment, and a timer can be used as the operation control means.

The stimulus may be a stimulus having a certain time width repeatedly, but in this case, the harmful birds and animals may become accustomed to the stimulus. Therefore, it is preferable to repeatedly apply stimuli having different time widths.

In other words, the control means can control the stimulating means so as to repeatedly generate a stimulus having a certain time width to warn or repel harmful birds and animals. Preferably, the stimulating means is controlled so as to repeatedly generate a stimulus having a width. The interval between stimuli may be constant, but in view of habituation of the harmful birds and animals, the stimuli may be generated at different time intervals.

The stimulus to the harmful birds and beasts is a sound such as a buzzer.
Although light such as a strobe light may be used, harmful birds and beasts are generally the most vigilant or repellent to humans and natural enemies, and it is preferable to employ an object that moves in association with these. Therefore, it is preferable to employ a mechanism that expands and contracts, a mechanism that expands, a mechanism that moves in and out, and a mechanism that moves, and it is more preferable to use such a mechanism in combination with a sound or light generation mechanism.

That is, the stimulating means can be constituted by a telescopic member supported by the mounting base and a driving means for expanding and contracting the telescopic member. Specifically, the extensible member may be a hose body whose tip is closed and contractable by its own weight, and the driving means may be an air compressor for supplying air to the hose body. As the hose body, for example, a rubber hose, a hose made of a synthetic resin thin sheet, a waterproof paper, or the like can be used. When a synthetic resin thin sheet or water-resistant paper hose is used, it is preferable to incorporate a wire spring inside to assist contraction.

[0015] The stimulus generation stage can be constituted by an inflating member supported by the mounting base and a driving means for inflating the inflating member. Specifically, the inflatable member may be a balloon body capable of contracting by its own weight, and the driving means may be an air compressor that supplies air to the balloon body.

Further, the stimulating means can be constituted by a rod-like member supported so as to be able to protrude and retract from the mounting base, and a driving means for causing the rod-like member to protrude and retract.

The bird and beast detecting means may be of any type as long as it can detect birds and beasts. For example, a vibration sensor for detecting vibrations caused by the movement of harmful birds and animals; An infrared sensor that detects the presence of a harmful bird, a heat sensor that detects the presence of a harmful bird or animal based on a temperature change in the area to be repelled, and a piezoelectric sensor can be used. A piezoelectric sensor has a piezoelectric element as a main component and is a sensor capable of extracting a change in pressure acting on the sensor as an electric signal.

The vibration sensor may be of any structure and type as long as it can detect vibration caused by the movement of the harmful birds and beasts. However, in order to reliably detect a slight vibration of the bird, a vibration sensor having the structure described in the following embodiment is preferable.

That is, the vibration sensor includes a conductor-made contact member supported by a base, a conductor-made contact member provided so as to be able to contact and separate from the contact member, and a conductor fixing the contact-piece member. Weight, and a spring member made of a conductor that vibrates and supports the weight based on the weight, and the weight vibrates due to the vibration caused by the harmful birds and animals entering the area to be repelled. Preferably, the contact member and the contact member are electrically connected. In this case, a part of the weight may be formed in a contact piece shape to have the function of the contact piece member, or the weight of the contact piece member may be made to have the function of the weight.

The vibration sensor having such a structure is also novel.
That is, according to the present invention, a vibration sensor suitable for detecting that a harmful bird or beast has entered a predetermined area,
A contact member made of a conductor is supported in the housing, and a contact piece made of a conductor is provided on the contact member so as to be capable of coming and going. The contact piece is fixed to a weight made of a conductor, and the weight is made of a conductor. It is supported by the housing by a spring member so that it can vibrate,
It is possible to provide a vibration sensor in which the weight vibrates due to external vibration received by the housing, and the contact member and the contact piece member are electrically connected.
