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 from flying to prevent nesting, feces damage and other harm caused by birds flying, and an installation structure thereof.

[0002] Recently, many birds such as crows and pigeons are found in various places. Pigeons are a symbol of peace and are popular among children because they are cute and popular among children. However, there are parts that are harmful to birds including this pigeon. For example, crows and other birds nesting on pole poles can cause electrical accidents, and excretion of birds pollutes various places and impairs aesthetics, and because feces are acidic, Corrosion to metal parts. It may also be a source of infection for various pathogenic bacteria (such as parrot disease). Also, in residential areas, crowing can also interfere with sleep, depending on the bird.

[0003] As means for preventing birds from flying,
Various measures have been implemented so far. This method includes installing needles, nets, etc. to directly prevent birds from flying, installing false eyes to cause birds to fear and keep them away, ultrasonic waves with wavelengths that birds do not like, A method of generating sound to prevent birds from flying, a method of installing a substance that emits an odor that birds dislike and keeping them away, and a local abnormal magnetic field based on the theory that birds' homing is related to the earth's magnetic field Numerous proposals have been made and implemented, such as a method of preventing birds from flying by doing so. However, none of these methods can provide an absolute effect.

[0004] Therefore, in recent years, in order to eliminate the uncertainty of the effect as seen so far, a spark shock using a high voltage difference voltage which has been conventionally used to keep a beast or the like from approaching has been used. A bird flying prevention method having an electric shock part has been adopted.

[0005] In this method, in a two conductor consisting of a non-insulated bare high voltage conductor having a high voltage difference voltage and a ground conductor, a part of a bird's body comes close to or in contact with one of the ground conductors. However, if another part of the body approaches or contacts the other high-voltage conductor, the resistance of the bird's body is much lower than the air between the two conductors, so the high-voltage conductor passes through the bird's body to the ground conductor. And a current flows to generate a spark.

The present inventors have previously proposed a novel construction of a bird flying prevention device having an electric shock portion comprising a high voltage conductor having a high voltage difference voltage and a ground conductor, as disclosed in Japanese Patent Application No. 7-87355 and 1995. Filed on November 27 (reference number P9557S012)
Although proposed in the patent application of 1) and the like, the birds coming prevention device having the electric shock part, such as these, can show a considerable effect.

For this reason, this kind of bird flying prevention device is
It is widely used, and in recent years, its use has been actively studied in order to prevent birds from nesting due to the arrival of birds on the pole poles or the like that cause electrical accidents.

[0008]

However, in such a use, this kind of bird flying prevention device does not always have a convenient structure to be installed on the arm of a utility pole or the like. The electric current naturally flows through the utility pole, and particularly in the case of a high-voltage electric current, the work of installation in close proximity is dangerous. In addition, a wire support insulator, a branch line fixing bolt, a suspension insulator for an overhead wire crossover, and the like are attached to the arm member, and the arm member itself has complicated projections in the vertical and horizontal directions. Therefore, it is not easy to attach the bird flight prevention device to the armature of the utility pole while avoiding these protrusions.

An object of the present invention is to solve the problem in installing a bird flight prevention device having an electric shock portion on the arm of such a power pole.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention holds a moving nut movably below an electric shock portion provided with a high voltage conductor having a high voltage difference voltage and a ground conductor. Attaching a moving rail having an opening on the lower side, a holding portion for holding both sides of the arm to the moving nut, a connecting portion located on the upper side and a magnet attached to the inner surface, and a fitting opening having an opening on the lower side. A bird coming-in prevention device which fixes a connecting portion of a cross-arm opening metal fitting having a cross-section lower opening and which is clamped to a cross-arm by a clamping portion of the cross-arm fixing metal.

[0011]

Embodiments of the present invention will be described with reference to the drawings.

First, the birds flying prevention device will be described in detail with reference to FIG. In FIG. 1, 1 is an electric shock unit, 2 is a rail for movement, 3 is a nut for movement, 4 is a bracket for fixing a brace, and 5 is a magnet.

The electric shock unit 1 is located in parallel with the longitudinal direction with a non-insulated bare high voltage conductor 12 and a ground conductor 13 having a high voltage difference voltage in the longitudinal direction of the base 11. .

The moving rail 2 holds a moving nut 3 and is formed with a holding portion 21 having a U-shaped bent portion on both sides so as to be slidable.
Has an opening 22 so as to be fixed to the moving rail 2 held.

The moving nut 3 is held by a holding portion 21 of the moving rail 2 and is formed in a slidable shape, and a female screw hole 31 is formed so that the arm fixing bracket 4 can be fixed by the bolt 8. Have been.

The arm bracket fixing bracket 4 is located on the upper side with the clamping sections 41, 41 for clamping both sides of the arm, and is fitted with the connecting section 42 of the clamping sections 41, 41 with the magnet 5 attached to the inner surface and the lower side opened. A bolt insertion hole 44 is formed in the lower portion of the cross section including the opening 43 and is fixed to the connecting nut 42 with the bolt 8 to the moving nut 3.

The magnet 5 is fixed to the inner surface of the connecting portion 42 of the bracket 4 by bolts 7. The magnet 5 used in this example can be turned on or off by a perforated handle 51.

In each of the parts thus constructed, the electric shock portion 1 is formed in advance on the rear surface of the base 11 of the electric shock portion 1 on the moving rail 2 and the screw hole 14 and the bolt formed in advance on the moving rail 2 are provided. The bolts 6 are integrally fixed by inserting the bolts 6 into the insertion holes 23, and the arm bracket fixing bracket 4 is connected to the bolt nut insertion holes 44 previously formed in the connecting portion 42 of the moving nut 3 held on the moving rail 2. Since it is formed in advance on the moving rail 3, it is integrally fixed by inserting the bolt 8 into the screw hole 31. In this embodiment, two sets of the arm bracket fixing brackets 4 are attached to the moving rail 2 via the moving bolts 3, but the number of sets may be determined as needed.

In this way, the birds flying prevention device is formed as a whole.

Next, the installation structure of the bird fly prevention device will be described with reference to FIG.

The birds flying prevention device is attached to the arm B of the telephone pole A,
Arms B between insulators C are held by holding portions 41 of arm brackets 4.
It is installed by sandwiching both sides of After installing the birds fly prevention device on the arm B, the magnetic force of the magnet 5 is perforated and the handle 51 is operated to turn the magnetic force ON, and the magnet 5 and the arm B are turned on.

Obstacles to wear. Therefore, the moving nut 3 is moved along the moving rail 2 so that the arm bracket fixing metal 4 is not affected by the protrusion D, and the position of the fixing metal 4 is adjusted before setting the arm bracket B.

FIG. 3 schematically shows a cross-sectional structure of the installation structure.

FIG. 4 is a schematic cross-sectional view showing another embodiment of the bird flying prevention device and the installation structure thereof. In the bird flying prevention device, the first embodiment is different from the bird flying prevention device in the longitudinal direction. The difference is that two were replaced by two instead of one.

FIG. 5 shows a state in which a plurality of birds flying prevention devices E are installed on a crosspiece B of a utility pole A and are electrically connected by a cord F.

Normally, a bird flying prevention device comprising a high voltage conductor having a high voltage difference voltage and a ground conductor is generally provided with a high voltage generator for each one. When installed close to each other as shown in Fig. 5, if the high-voltage generating device is provided in one of the electric shock parts, a plug receiving hole is formed in each of the high-voltage generating devices, and the cord is electrically connected by the cord F. Since it is enough, it is not necessary to equip other electric shock parts. Therefore, cost can be greatly reduced.

Although the present invention is configured as described above, this kind of bird flying prevention apparatus is often carried out by a work robot arm H on a bucket truck G as shown in FIG.

Therefore, in order to facilitate the work, a perforated ear 45 for scissoring the robot arm is fixed to the arm bracket fixing bracket 4 as shown in FIG. 7, or each of the electric shock parts is connected as shown in FIG. A rubber cover K may be placed over the grip of the plug J to be connected.

Since the perforated ears are fixed to the arm bracket fixing bracket 4, the work robot arm can be easily pinched, and the hole can be pierced with a stylus to prevent falling. The above-described perforated handle 51 of the magnet 5 is also a preferable example in the operation of the operation robot arm. Further, by slipping the rubber cover K over the grip portion of the plug J, slipping from the working robot arm can be prevented.

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

The attachment to the crosspiece is performed by using a crosspiece with a lower opening in cross section comprising a holding portion for holding both sides of the crosspiece, a connecting portion located on the upper side and having a magnet mounted on the inner surface, and a fitting opening with a lower side opened. Since the work can be performed from the fitting hole, the work can be easily performed by the work by the work robot arm. Further, since the magnetic force is applied to the arm by the magnetic force of the magnet, the work is simple and the fixation is strong.

Even if there is a protrusion on the arm, the arm fixing bracket holds the moving nut so as to be movable, and is connected to the moving rail having an opening at the lower side by fixing the connecting nut and the connecting nut. Therefore, this can be avoided by moving the moving nut along the moving rail.
