Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird and beast repellent device for preventing harmful behavior by birds and beasts having a charging sensation such as crows.

Countermeasures against damage caused by birds and beasts such as crows such as dust clams at garbage collection points and food damage to agricultural products have been long-standing issues. Especially for electric power companies, if a crow nests on a utility pole or the like, the nest may touch an electric wire and cause a power failure, so the nest must be removed, which requires a great deal of labor. There is.

BACKGROUND ART Conventionally, various repellent measures have been implemented in order to prevent behaviors such as nesting of crows on electric poles, feeding damage on farmland, and rubbing of garbage at garbage collection points. For example, in the conventional repelling means, a bird damage prevention tool that repels crows by shaking a tape or the like that reflects light, or a large number of transparent or translucent wires are attached to a tape-shaped support, There is a device that avoids crows by swinging (see Patent Document 1). There is also a method in which a crow-like object is installed to give an illusion that there is another crow, and birds and beasts such as a crow cannot be brought close to each other (see Patent Document 2). In addition, a device that emits a sound to surprise and avoid birds and beasts is generally known. Alternatively, there is also a repellent device that uses a magnet that emits magnetism that crows dislike (see Patent Document 3) and a repellent device that uses a repellent such as capsaicin.

Japanese Patent No. 3540270 JP 2005-058092A Japanese Patent No. 5767767

In the conventional measures, if the diffuse reflection of light that crows hate is used, there is a problem that the reflective material is glitter and the shiny material damages the landscape. In addition, there is a problem in that the generated sound becomes noise when it is a means of generating a sound and making it startle. As countermeasures against crows that repel crows using magnetic force or using repellents, pets and other animals are adversely affected as countermeasures against damage that crows attack pets and livestock. Was a concern.

Among other things, crows are known to be highly intelligent, and among the conventional repellent devices and methods that can be seen, heard, smelled, and touched, crows can identify the device and method, so that they can be used over time. There was a problem that the repellent effect was reduced and the effect did not last long because the crows recognized that the crows would not be harmed after being installed for a while and gradually approaching.

The present invention provides a bird and beast repellent device that utilizes the habit of the crows and has a wide range of effects while the installation cost and the running cost are low in order to solve the above problems, and that the repellent effect continues. With the goal.

On the other hand, because the work that can be carried out by people with disabilities is limited at the delivery facility, it is not possible to secure the work necessary for sound management of the work place, and there is a social problem such as the occurrence of a work place that collapses. It has occurred. The purpose of this technology is to secure work that can be performed by people with disabilities.

In order to tackle such a problem, the inventor investigated the ecology of crows and found that there are regularly arranged sensory receptors around the roots of the crows' nose hairs, and these receptors receive sensations due to electrification and the like. I knew that what was pointed out by experts. Therefore, when the inventors conducted an experiment in which the crows were subjected to discharge irradiation, the crows in the normal state disliked the discharge, except for the crows whose nose hair was wet and became difficult to be charged due to bathing or the like, and caused a flight flight. It was confirmed to be taken. In addition, from the examination of the experimental results, it was found that the crows hate spike-like discharges with a fast potential rising speed. It was also confirmed that a pair of crows with children would not take flight until the child was left behind. From this, it was found that this method did not cause damage to birds and beasts that conflict with the Bird Conservation Law.

On the other hand, a thin film piece made of a conductive material has characteristics such as reduced electric resistance, and has a low electric resistance, and the movement of electrons is difficult to be suppressed. It has the property of being easy. This is thought to be caused by the uniform atomic arrangement on the glossy surface of the conductive material thin film piece, but due to its characteristics, it is possible to perform discharge that crows dislike by using the conductive material thin film piece. I understood.

In order to solve the above problems, the invention of claim 1 is provided with a plurality of thin film pieces of a conductive material, and uses the characteristics of the crow and the characteristics of the thin film piece of a conductive material, and the thin film pieces of the conductive material are arranged in the entire area direction or a fixed direction. It is characterized by stimulating birds and beasts having a charging sensation including crows by a dischargeable discharge body.

According to this aspect of the invention, the electric discharge of the bird-repelling device causes the electric discharge, which is disliked by birds and animals having a charging sensation including crows.

According to a second aspect of the present invention, in the bird and beast repellent device according to the first aspect, a detection unit that detects the bird and the beast is provided, and the discharge control unit discharges the discharge body when the bird and the beast is detected by the detection unit. The feature is that

According to a third aspect of the invention, in the bird and beast repellent device according to any one of the first and second aspects, the discharge control means discharges the discharge body by applying a negative potential to the thin film piece. The feature is that

A fourth aspect of the present invention is the bird and beast repellent device according to any one of the first and second aspects, wherein the discharge control means causes the thin film pieces to rub against each other as the discharge body shakes. Then, the electric charge charged in the thin film piece is discharged.

According to the invention of claim 5, a plurality of thin film pieces made of a conductive material are provided, the discharge body is capable of discharging, and a mounting body for mounting the discharge body on an animal including a dog. When the discharge body shakes, the electric charge charged in the thin film piece is discharged to stimulate birds and animals having a sensation of charging including crows.

According to a sixth aspect of the present invention, in the bird and beast repellent device according to the fifth aspect, the discharge body includes a positive charging member made of a material easily charged positively, and a negative charging member made of a material easily negatively charged, The positive charging member and the negative charging member are slidably attached to each other, and the positive charging member and the negative charging member slide so that either the positive charging member or the negative charging member can be moved. It is characterized in that electric charges are discharged from the thin film piece of the conductive material arranged on the urchin to stimulate birds and animals having a sensation of charging including crows.

According to the invention of claim 1, the crow includes the crow in the vicinity of the bird and beast repellent device by discharging the discharge body by utilizing the habit of dislike of spike-like discharge having a high potential rising speed. Birds and animals having a sensation of electrification can be stimulated, eliminated from the discharge area, or prevented from remaining in the discharge area. Therefore, by discharging from the bird and beast repellent device at or near the place where damage is expected, the damage to the birds and beasts can be effectively prevented. Further, although the discharge stimulates the charging sensation of the crow, the crow cannot identify the device and method due to the speed of the air-borne transmission, so the repellent effect continues.

In addition, since the discharger that can discharge in the whole area or in a fixed direction only needs to be provided with a plurality of thin film pieces of conductive material, the structure is simple, and it is possible to produce it at a child-rearing facility. It is possible to reduce maintenance costs.

According to the invention of claim 2, it is possible to timely discharge only when a bird or a beast is detected. Thereby, the repellent effect can be improved, and the birds and beasts can be prevented from becoming accustomed to the stimulus, and the repellent effect can be maintained.

According to the third aspect of the present invention, since the negative potential is positively applied to the thin film piece, it is possible to give an electric charge suitable for the repelling effect and discharge the thin film piece. As a result, it becomes possible to efficiently exhibit the repellent effect.

According to the invention of claim 4, since the discharge body is shaken by the action of wind or the like, static electricity is generated in the thin film piece, and the thin film piece can be discharged, so that the electric charge is positively applied. It can be discharged without mounting, and it can be expected to save cost and reduce the labor of installation.

According to the invention of claim 5, the bird and beast repellent device is attached to an animal such as a dog, and the animal and animal are discharged by the movement of the animal to give a stimulus to birds and beasts having a charging sensation including crows. It is possible to prevent the animal from being attacked by the bird and beast without approaching the animal and the bird and beast.

Also, since the structure of the mounting body for mounting a dischargeable body on animals including dogs is simple, it is possible to produce at a delivery facility and reduce production costs and maintenance costs. Is.

According to the invention of claim 6, the bird and beast repellent device is attached to an animal such as a dog, and the discharge body is discharged by the positive charging member and the negative charging member sliding along with the movement of the animal. Since it can be discharged well and surely gives a stimulus to birds and animals having a charging sensation including crows, the animals do not approach the animals equipped with the birds and animals repellent device, and the animals are attacked by the animals and birds. You can prevent being exposed.

(Embodiment 1)
Hereinafter, the present invention will be described based on the illustrated first embodiment. In the first embodiment described below, a crow is assumed as a bird/beast to be avoided.

The feature of the first embodiment is that the discharge control means has a circuit for generating a high voltage, and the regular or irregular timing is the timing for detecting a crow.

As shown in FIG. 1, the bird and beast repellent device 10 discharges the discharge body 20 in which a plurality of thin film pieces 21, 21,... Made of a conductive material are arranged and the discharge body 20 at regular or irregular timing. And a discharge control means 30. The discharge control means 30 is housed in a housing 40, and two support pillars 41, 41 are erected in the housing 40 in a separated state.

The discharge body 20 is composed of a conductor 22 and a large number of thin film pieces 21, 21,... And the thin film piece 21 is, for example, a small piece of aluminum foil in the form of an elongated tape. Each thin film piece 21 is attached at its central portion to the conductor wire 22 and is in a radial shape when viewed from the line direction of the conductor wire 22, and is electrically connected to the conductor wire 22. A large number of such thin film pieces 21 are attached over substantially the entire length of the conductive wire 22.

Both ends of the conductor 22 of the discharge body 20 are attached to the upper portions of the two support columns 41, 41, respectively, and the conductor 22 is passed with a slight slack. At this time, the thin film pieces 21, 21,... Are placed so as not to come into contact with the ground or other equipment.

The discharge control means 30 includes a piezoelectric element 31 that generates a high voltage by applying a pressure. Electrodes 32, 32 of the piezoelectric element 31 are connected to both ends of the conductor wire 22 of the discharge body 20, respectively. The generated high voltage is applied to the discharge body 20.

The sound collecting microphone 33 is a part of a crying sensor as a detecting means, and the piezoelectric element 31 is activated by collecting a crowing sound.

Although not shown, there is a means for pressurizing the piezoelectric element 31 when the sound collecting microphone 33 detects a crowing voice, and the pressurization causes a high voltage to be generated from the piezoelectric element 31.

When a high-voltage charge generated from the piezoelectric element 31 is applied to the conductive wire 22 from the electrodes 32, 32, the charge moves to the thin film pieces 21, 21,..., From the thin film pieces 21, 21,. It will discharge and stimulate the crows.

As described above, according to the bird-repelling device 10, the crow does not approach the periphery of the bird-repelling device 10 when the crowing voice is detected, because the discharge body 20 discharges the crow's hating. That is, the crow can be repelled, and damage from the crow can be prevented. Since the crow is discharged only when the crow is detected, it is difficult for the crow to get used to the stimulus due to the discharge, and the repellent effect continues. Furthermore, it is considered that the discharge between the crows, which is a means of communication between the crows, is detected to discharge the crows, so that the communication between the crows is hindered, and the crow's discomfort is thought to be increased, and a further repellent effect can be expected.

The piezoelectric element 31 is for giving electric charge to the discharge body 20, and instead of this, may be provided with a high voltage generating device used in a circuit of an electric gun, for example, and a detecting means. Is not limited to the sound collecting microphone 33, and image recognition by a proximity sensor or a camera may be adopted.

(Embodiment 2)
FIG. 2 shows the second embodiment of the present invention. As shown in FIG. 2, the bird and beast repellent device 60 includes a discharge body 20 and a discharge control unit 70 that charges the discharge body 20 and emits an electric charge.

Since the discharge body 20 is the same as that described in the first embodiment, the detailed description thereof will be omitted by giving the same reference numeral.

The discharge control means 70 is configured to apply vibration to the discharge body 20 so that the thin film pieces 21 rub against each other and are charged to discharge, and the discharge motor 70 is disposed in the case 73 and the case 73. It is composed of two support pillars 74, 74 that stand upright and support the discharge body 20.

A weight eccentric to the motor shaft is fixed to the vibration motor 71, and the rotation of the motor causes the eccentric weight to rotate and generate vibration.

The case 73 is divided into an upper case 73a and a lower case 73b, and the upper case 73a and the lower case 73b are connected by a coil 73c to form a rectangular parallelepiped case 73, and the lower case 73b. On the other hand, since the upper casing 73a is likely to vibrate, the vibration of the discharge body 20 can be further promoted. The vibration motor 71 is arranged on the lower surface of the upper plate of the upper casing 73a.

The two support pillars 74, 74 are provided upright on the upper casing 73a while being appropriately separated from each other, and the conductor wire 22 of the discharge body 20 is attached between the tips of the two support pillars 74, 74.

The means for taking a regular or irregular timing is a timer 72 which outputs a signal at a preset time or a fixed time, and a signal emitted at the set time or a fixed time is input to the discharge control means 70 and the vibration motor 71 rotates. It is like this. Although such a timer 72 is provided in the case 73, it may be provided in either the upper case 73a or the lower case 73b.

Further, among the above-mentioned regular or irregular timing, the "set time" may be, for example, an early morning when the crow's activity becomes active or the time to return home, etc. Can be repelled. Furthermore, the "regular time" is, for example, every one hour or every two hours, and it is possible to discharge periodically at a place where it is not desired to approach the crow.

According to the bird and beast repellent device 60 according to the second embodiment, vibration is generated by rotating the vibration motor 71 at a regular or irregular timing, that is, a time preset by the timer 72 or at a fixed time. It is propagated to the discharge body 20 and discharged from the thin film piece 21.

That is, when the vibration motor 71 is rotated and vibration is generated, this vibration is propagated to the discharge body 20 through the upper housing 73a and the support columns 74, and when the discharge body 20 is vibrated, the thin film piece 21 is shaken and the thin film piece 21 is shaken. The pieces 21 are rubbed against each other and charged, and the thin film pieces 21 are discharged by this charging.

Moreover, in the bird and beast repellent device 60 according to the second embodiment, since the discharge body 20 is vibrated to cause the electric discharge, a circuit for generating a high voltage as in the first embodiment is not required, The structure can be relatively simple.

Further, since the bird and beast repellent device 60 discharges at regular or irregular timing, the crow is less accustomed to the stimulus due to the discharge, and the repellent effect can be maintained.

Such a bird and beast repellent device 60 has components such as the discharge body 20, the discharge control means 70, and the timer 72 attached to the housing 73, so that it is easy to carry and a place where the crow is not desired to approach, for example, It can be easily installed at a garbage collection site, a crop cultivated land, a utility pole where there is a concern of nesting, or in the vicinity thereof.

In addition, in the second embodiment, the case 73 is divided into the upper and lower parts and coupled by the coil 73c, but the present invention is not limited to this, and the vibration motor 71 may be formed as an integrated case. The vibration can be propagated to the thin film piece 21 through the housing, the support columns 74, 74, and the discharge body 20, and the thin film piece 21 can be discharged.

By the way, the discharge body 20 can have the directionality of the discharge depending on its shape and the mounting position of the thin film piece 21 made of a conductive material. 3A to 3E exemplify the discharge body 20 in a mode in which the directionality of discharge is changed. The bird and beast repellent device shown in this figure has a discharge body 20 in which a plurality of thin film pieces 21, 21,... Of conductive material are arranged, a discharge control means 80 for applying an electric charge to the discharge body 20, and a power supply to the discharge control means 80. Power source 81 and is connected to ground 82.

FIG. 3A shows a discharge body 20 formed by attaching thin film pieces 21, 21,... To the entire surface of a spherical body. With this discharge body 20, radial discharge can be generated in all directions.

FIG. 3( b) shows a discharge body 20 horizontally installed with thin film pieces 21, 21,... Attached to the outer peripheral surface of an annular body. With this discharge body 20, a radial discharge can be generated in the horizontal direction.

FIG. 3C shows a discharge body 20 constructed by attaching thin film pieces 21, 21,... To the upper half of the spherical body. With this discharge body 20, it is possible to perform a radial discharge in the upward direction.

FIG. 3D shows a discharge body 20 configured by attaching thin film pieces 21, 21,... To the lower half of the spherical body. With this discharge body 20, a radial discharge can be generated in the downward direction.

By applying these, the discharge body 20 in which the locations where the thin film pieces 21, 21,... Are densely attached to the spherical body and the locations where the thin film pieces are loosely attached are provided in the direction corresponding to the locations where they are densely attached. Can produce many radial discharges.

3(e) is a cylindrical discharge shield in which thin film pieces 21, 21,... Are attached to the ends of a cylindrical body so as to surround the thin film pieces 21, 21,. The discharge body 20 in which the conductive member 23 is installed is shown. According to this discharge body 20, the discharge that spreads radially can be unidirectionally discharged by the discharge shield member 23 installed around the thin film pieces 21, 21,.

As described above, the shape of the discharge body 20 and the attachment location of the thin film piece 21 can be selected in an optimum shape depending on the installation location and the installation form. For example, when it is not desired to bring the crow close to only one limited place, the thin film piece attachment location of the discharge body 20 (opening portion of the discharge shield member 23) shown in FIG. It should be installed.

(Embodiment 3)

The bird and beast repellent device 90 includes a discharge body 100 and a mounting body 110.

The discharge body 100 includes a cylindrical positive charging member 103, a round bar negative charging member 104, and a thin film piece bundle including a large number of thin film pieces 101, 101,... Attached to both ends of the negative charging member 104. And 102 and 102.

The positive charging member 103 is a glass cylindrical member that is relatively easily charged positively in the frictional charging train, and the negative charging member 104 is made of a vinyl chloride rod that is relatively easily charged negatively in the frictional charging train. The glass tubular member of the positive charging member 103 has an inner diameter slightly larger than the outer shape of the vinyl chloride rod of the negative charging member 104, and the length of the positive charging member 103 is shorter than that of the negative charging member 104. .. The negative charging member 104 is slidably inserted in the cylinder of the positive charging member 103. One retaining pin 105, 105 is attached to each of the side surfaces near both ends of the negative charging member 104 to prevent the negative charging member 104 from falling off when sliding.

Then, when the negative charging member 104 is slid on the positive charging member 103, static electricity is generated, and the positive charging member 103 is charged with a positive charge and the negative charging member 104 is charged with a negative charge.

Similar to the first and second embodiments, the thin film piece bundle 102 is formed by bundling thin film pieces 101 made of aluminum foil in the form of elongated tapes at their central portions.

Such thin film piece bundles 102, 102 are attached to both ends of the negative charging member 104 in a state where electrical conduction is achieved, and when the positive charging member 103 slides on the negative charging member 104 and becomes charged, The thin film piece bundles 102, 102 are also negatively charged.

The mounting body 110 is for mounting the discharge body 100 on the small dog D, and in the third embodiment, a dog collar 110 is used.

The collar 110 is composed of a belt 111 and a buckle 112 connecting both ends of the belt, and the positive charging member 103 of the discharge body 100 is attached to the belt 111 of the collar 110. As a method of attaching the positive charging member 103 to the collar 110, for example, an adhesive material can be considered.

In the third embodiment, the collar 110 is given as an example of the attachment body for attaching the discharge body 100 to the small dog D, but the present invention is not limited to this, and the discharge body 100 can be attached to the existing collar attached to the small dog D. It may be a hook or the like attached by hooking.

And 104 generate friction and generate static electricity. As described above, due to this static electricity, electric charges are emitted from the thin film piece bundles 102, 102 attached to both ends of the negative charging member 104.

Therefore, when the small dog D walks, the discharge action works around the small dog D and the crow C does not approach, and the small dog D is prevented from being attacked by the crow C.

Such a bird and beast repellent device 90 has a simple structure in which a rod-shaped member is inserted into a tubular member and the thin film piece bundles 102 are attached to both ends of the rod-shaped member. Is small, and since it is discharged by static electricity, it does not affect the small dog D.

Although the first, second, and third embodiments of the present invention have been described above, the specific configuration is not limited to the above-described embodiments, and changes in design within the scope not departing from the gist of the present invention may be made. Even if it is included in this invention. For example, although aluminum foil is used as the thin film pieces 21 and 101 made of a conductive material, when the aluminum foil is installed in an environment where irregular reflection of light is not preferable, the surface of the aluminum foil is coated with a low reflection material. May be. Alternatively, instead of the aluminum foil, for example, a carbon fiber sheet of a conductive material or the like can be expected to have the same effect. In the third embodiment, the bird and beast repellent device 90 is attached to the small dog D, but the design of the collar 110 is changed so that the dog and animal repellent device 90 is attached to livestock such as cows that are damaged by crows and human bodies such as when jogging.
