Description

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, many pigeons are inhabiting in various places, and many pigeons are seen especially in parks and shrines and temples. Pigeons are a symbol of peace, and because they are cute, they are popular with everyone and are very popular with children. However, this pigeon also has some harmful parts. This is because the excrement of feces pollutes various places and spoils the appearance, and the feces are acidic, which causes corrosion of metal parts. It may also be a source of infection of various pathogenic bacteria (parrot disease, etc.). Besides, not only damaging feces but also screaming in the residential area disturbs the sleep and is harmful.

Various measures have been taken so far as means for preventing flying of birds such as pigeons. As means for this, a method of directly preventing the birds from flying by installing a needle, a net, etc., a method of setting a pseudo eyeball to scare the birds and keeping them away, ultrasonic waves of a wavelength that birds dislike, From the theory that the sound is generated to prevent birds from flying, the substance that emits the odor that birds dislike is placed away from them, and that the homing property of birds is related to the earth's magnetic field, the abnormal magnetic field is locally generated. A great number of proposals have been made and implemented, such as a method for preventing the arrival of birds by generating them. However, none of these methods can obtain an absolute effect.

Therefore, in order to eliminate the uncertainty of the effect that has been seen so far in recent years, birds caused by a spark shock using a high voltage differential voltage which has been conventionally used to keep animals and animals away from each other. Flying prevention methods have been adopted.

In this method, as shown in FIG. 9, in a two-conductor consisting of a high voltage conductor 1 having a high voltage difference and a ground conductor 2, one of the ground conductors 2 has a part of the body of the bird 3 ( When the part A of the foot in the figure approaches or contacts, and another part of the body (point B of the beak in the figure) approaches or contacts the other high-voltage conductor 1, the resistance value of the bird's body becomes two. Since it is much smaller than the air between the conductors, a current flows from the high-voltage conductor 1 through the body of the bird 3 to the ground conductor 2 to generate a spark.

If the high-voltage generator 4 controls the flowing current to a current that is safe to the body and is similar to the static electricity that is experienced in the doors of automobiles, birds will be violent in a part of the body. Receive a spark shock. Sparks are shocked by the fact that the objects in the high-temperature plasma-like air layer of the electric spark when igniting skin nerves.

More specifically, as shown in FIG. 10, Vpp of several thousands to tens of thousands of volts and several μsec to several msec are set so that the high voltage generator 4 does not cause any damage to the body.
And the voltage continuation time is shortened, and the generation cycle T is several hundred ms.
The energy of one spark is reduced as much as possible from ec to several minutes to make it as close as possible to the electrostatic shock.

[0008] The timing (T
At timing 1), if birds come into contact with the high-voltage conductor 1 and the ground conductor 2 in FIG. 1, they will be connected by a low conductor, and only a small current inversely proportional to the ohmic resistance of the conductor will be applied. No flow, no spark, no spark shock. Therefore, in such a case, the effect of giving a spark shock to the bird by using the method and preventing the bird from flying is lost.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to solve the problem that a high voltage conductor and a ground conductor are connected to each other due to pre-contact of birds and no spark is generated.

[0010]

SUMMARY OF THE INVENTION In the present invention, the above object consists of two conductors, a high voltage conductor having a high voltage difference voltage and a ground conductor, and when a bird approaches or contacts, a current flows between the two conductors. In a bird flying prevention device that flows and causes a spark shock to birds, the problem is solved by having a structure in which at least one conductor does not contact the birds.

Specifically, in the bird flying prevention device, by positioning at least one conductor in a groove formed in an insulator having a length in the length direction of the conductor, An example is a structure in which the bird does not come into contact with it, or at least one of the conductors is covered with an insulator having a gap at an appropriate interval so that the conductor does not come into contact with the bird.

[0012]

The present invention consists of two conductors, a high voltage conductor having a high differential voltage and a ground conductor, and when birds come close to or in contact with each other, a current flows between the two conductors to cause a spark shock to the birds. Since the flying prevention device has a structure in which at least one conductor does not contact the bird, the flying bird does not contact both the high-voltage conductor and the ground conductor at the same time. Therefore, when the birds approach or come into contact with any of the conductors, a spark is surely generated, which gives a strong shock to the birds.

[0013]

EXAMPLES Examples of the present invention will be described below. FIG.
FIG. 2 is a schematic perspective view showing a state in which a bird has come to the birds flying prevention device according to the present invention. In the figure, both the high voltage conductor 1 and the ground conductor 2 are configured to be located in a groove 5a formed in an insulator 5 having a length in the length direction of the conductor. Details of the structure in which both conductors are located in the grooves 5a formed in the insulator 5 are as shown in FIG. FIG.

In this figure, the high voltage conductor 1 is located in the groove 5a of the insulator 5. In FIG. 3A, the ground conductor 2 is a foil-shaped one.

FIG. 4 shows the relationship between the groove and the conductor. The groove entrance gap G is preferably smaller than the diameter dφ of the conductor located in the groove 5a, in this figure, the high voltage conductor 1, and this prevents the conductor from jumping out of the groove 5a.

FIG. 5 shows the positional relationship between the insulator and the conductor, wherein the distance between the upper surface of the high-voltage conductor 1 is indicated by h. h is determined by the magnitude of Vpp shown in FIG.
For example, if Vpp is 10,000 volts, the separation distance h is at least 1
The range from mm to maximum 8 mm is the most efficient area.

In the birds flying prevention apparatus thus constructed, even if the birds 3 fly and come into contact with the conductor or the insulator as shown in FIG. 1, at least one of the conductors is located in the groove of the insulator. The conductor does not come into contact with the bird's body.

Here, a high resistance material such as rubber, synthetic resin, dry wood or the like can be used for the insulator, and conductors such as electric conductors such as copper wires, aluminum foil, conductive paint and the like are used. You.

Further, it is possible to reduce the power consumption by connecting the light detecting device to the high voltage generating device and operating it only in the daytime.

[0023]

Since the present invention is constructed as described above,
It has the following effects. In the first, second, and third aspects, a high voltage conductor having a high voltage difference voltage and a ground conductor are provided, and when a bird approaches or contacts, a current flows between the conductors to spark the bird. In the birds flying prevention device that gives a shock, at least one of the conductors does not contact the birds, so the flying birds do not contact both the high-voltage conductor and the grounding conductor at the same time. The phenomenon that spark does not occur can be prevented, and a certain spark shock can be given to birds. This can effectively prevent birds from flying.

According to the second aspect of the present invention, at least one of the conductors is located in a groove formed in the insulator having a length in the longitudinal direction of the conductor, so that when birds fly, the groove of the insulator is formed. There is no contact between the conductor and the bird's body. Also, since the groove is not closed, it does not interfere with the flow of current between the two conductors. Therefore, when birds fly,
Since it does not come into contact with either one of the conductors, a spark is reliably generated and shocks the birds, so that the birds can be effectively prevented from flying.

In claim 3, at least one of the conductors is covered with an insulator having gaps formed at appropriate intervals. Therefore, even if a bird flies and comes into contact with the other conductor, the body of the bird is covered. Does not come into contact with certain conductors. In addition, since gaps are formed at appropriate intervals in the insulator, the flow of current between the two conductors is not hindered. Therefore, when the birds fly, they do not come into contact with either one of the conductors, so that a spark is reliably generated and the birds are shocked, so that the birds can be effectively prevented from flying.
