Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird and beast protective electric wire to which a high-voltage current is applied. The electric wire is erected over a required length so that the electric wire can be stretched under a predetermined condition. The present invention relates to a holding tool and a tensioning tool for a bird and beast protective electric wire for the purpose of holding each of them and maintaining a tension state. Further, the present invention relates to a bird damage prevention device which can be attached to a column or a horizontal rod and can be given an electric shock, especially when a large bird is retained.

[0002]

2. Description of the Related Art Conventionally, an invention and an invention of an electric wire for bird and beast protection for the purpose of preventing bird damage such as sparrows, gourd birds, crows, pigeons, and bulbuls invading paddy fields, fields and orchards and devouring agricultural crops (Japanese Patent Laid-Open No. 2000-10681)
1 gazette, utility model registration No. 3012207).

This bird and beast protection electric wire utilizes the bird's habit of once landing on a high perch when a bird is stalking a crop, and when the bird stays, a high voltage electric shock is applied to the bird. It is used to repel birds that give.

[0004]

The paddy field, field and orchard where the above-mentioned electric wire for bird and beast protection should be installed has a vast area, and it is preferable that the electric wire is in a uniform state in a tense state. There was a problem that it became more difficult to maintain tension as the length of time became longer.

Further, as described above, the bird and beast protection electric wire is an electric shock to the bird when it stays in the electric wire and repels the bird, so that the bird remains in the electric wire. Also needs to keep the wires straight. In order to reduce the looseness of the electric wire when the bird stays, it is necessary to increase the number of holding points of the electric wire, and to increase the number of holding points of the electric wire, it is necessary to increase the number of columns.

However, the increase in the number of holding points of the electric wire also increases the labor and material for erection of the electric wire, and depending on the shape, there is a problem that the support pillar becomes a perch of a bird.

Further, it is preferable to maintain a proper tension even when the bird is not staying. That is, considering that the habit of the bird is used, it is not preferable that the electric wire is too slack in order to keep the bird on the electric wire. In order to lay the wires without slack, it is necessary to firmly pull the wires to the struts at both ends of the place where the wires are laid, fix the ends of the wires to each stanchion, and always apply a constant tension. .

Further, as a problem when using an electric wire for protecting birds and animals, there is also a problem of large birds. That is, even if the electric wire has a thickness and strength sufficient for sparrows to stay, it is too thin or insufficient for large birds, and the large birds do not try to stay. It is difficult to repel large birds. Further, even if a large bird stays in such an electric wire, the strength of the electric wire is not sufficient and the electric wire may be cut, which is a problem.

[0009]

SUMMARY OF THE INVENTION According to the present invention, an electric wire is sandwiched and held, and the electric wire is stretched and erected on a strut through a coil spring so that the looseness is small and the tension is always maintained. It is a solution to the problem.
In addition, in order to repel large birds, instead of using electric wires, the large birds are retained in a grasping rod having a core body having sufficient strength to solve the above problems.

That is, the invention of the holder is an electric wire holder for holding an electric wire to be erected for each predetermined section, characterized in that the main body portion is provided with an electric wire clamping means and a support means for attaching to the column. It is a retainer for a bird and beast protective electric wire. Further, the main body is a tubular body, and the wire holding means is a slit provided in the tubular body for holding the electric wire and a fixing tool for holding and fixing the electric wire. The fixture is a cap or a ring that fits into the cylinder.

Further, the main body is a plate, and the wire holding means is a plurality of slits for holding the wires provided in the plate and a cover of the plate for preventing the wires from being pulled out. is there.

The attaching means is a holding tool which is a U-shaped holding tool.

The invention of a tensioning tool is a tensioning tool for a bird and animal protection wire characterized in that an insulator for fixing an electric wire is connected to one end of a coil spring, and a fixing means for fixing to a support is connected to the other end.

Next, the invention of a bird damage prevention device comprises a grip bar in which a plus-side conductor and a minus-side conductor are arranged to face each other along a core rod made of an insulator, and a fixture to a support. This is a bird damage prevention device.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Since the electric wire is applied with a voltage of several thousand volts, an insulating material such as a resin that can withstand the electric wire is used as the material of the main body of the bird and animal electric wire holder.

The main body may be a tubular body having a slit at one end for holding an electric wire. The slit may have a width and a depth that allow the electric wire to be inserted and held. If the slit is provided on the cap side as well, the slit of the main body portion and the slit of the cap overlap, so that the depth of the slit can be made shallower by that amount.

The cap is preferably capped on the main body so as to narrow the width of the slit of the main body, and the electric wire is pressed and clamped by the slit so that the electric wire does not move. In addition, it is preferable to prevent rainwater, dust, etc. from entering the inside of the main unit by the cap and to prevent the electric wire in the slit part from getting wet, but instead of the cap, a simple ring is provided in the main unit slit. It can also be attached to the surrounding area.

The main body may be a plate instead of the cylinder, as long as it can hold an electric wire. The plate body is provided with two or more slits, and the electric wires can be held by alternately sandwiching the electric wires there.

The mounting means may be a U-shaped clamp so that mounting and dismounting on the column can be completed with one touch. In the U-shaped clamp, if the U-shaped opening side is curved smoothly toward the outside, the clamp is attached to the column by bringing the curved portion into contact with the column and pushing the column. Due to the elasticity of, the opening side opens and it can be attached to the column. Even when it is detached from the column, the opening can be opened by the elasticity of the sandwiching tool and easily removed. Also,
As the attachment means, the cylindrical body of the main body may be directly covered on the upper end of the support column.

The coil spring of the tensioning tool may have an elasticity capable of giving a tension to the extent that the electric wire after installation is not loosened significantly.

Further, as the means for fixing the tensioning tool to the column, a U-shaped clamp similar to the mounting means to which the above-mentioned bird and beast protective wire holder is mounted can be adopted.

The grip bar of the bird damage prevention device is a large bird,
For example, a crow can be caught and stayed. The thickness and strength of the core rod made of an insulating material that composes the grip rod are determined in consideration of the retention of large birds. This gripping rod is attached to a support post or the like so that the bird can be easily gripped (height equivalent to the ground level, slightly higher than other nearby objects so that the bird can easily stay), but it is usually horizontal to the ground. It is attached so that.

The plus-side conductor and the minus-side conductor arranged on the core rod are attached to the core rod so that they do not contact each other, and are spaced apart from each other so as not to spark when a high voltage is applied. Then, when the bird is grasped by the grasping rod, a high-voltage electric shock can be given through the legs of the bird. For example, it is possible to arrange a plate-shaped positive-side conductor on one side of the core rod and a plate-shaped negative-side conductor on the other side along the longitudinal direction of the core rod. Also,
It is also possible to wind two conductive wires, which are spaced apart from each other so as not to spark when a high voltage is applied, around the core rod, and use one wire as a positive-side conductor and the other wire as a negative-side conductor.
If the distance between the two conductive wires is smaller than the width of the bird's foot, a high-voltage electric shock can be given when the bird stays on the grip bar.

The attachment is used to attach the bird damage prevention device to a column or the like, and has, for example, a pipe shape that can be fitted to the column. As mentioned above, the grip bar is usually
Since it is attached so as to be horizontal to the ground, the shape of the attachment can be changed to various shapes such as a straight line or an L shape so that the grip bar is substantially horizontal to the ground. . Further, the angle of the joint between the grip portion and the fixture can be variously changed so that the grip bar is horizontal with the ground.

For example, if the mounting bar is linear and the joint with the grip bar is at a substantially right angle, the grip bar can be mounted substantially horizontally to the ground. That is, the grip portion and the attachment are formed in a T shape. By doing so, if the top of the pillar standing upright to the ground is crowned or the end of the horizontal rod is crowned, the gripping rod and the pillar or the horizontal rod form a T-shape. Bird damage control devices can be installed so that the bar is approximately level with the ground.

If the mounting rod is linear and the connection with the gripping rod is substantially linear, the gripping rod and the horizontal rod form a linear shape by crowning the end of the horizontal rod. Bird damage control devices can be installed so that the bar is level with the ground.

The point is that the attachment can be changed into various forms in relation to the grip bar according to the installation conditions required for the bird damage prevention device. Further, a plurality of attachments can be provided depending on the length of the grip bar, the size of the target bird, and the like.

Since they are overlapped by assembling, the height of the cylindrical body 17 can be made lower than that of the cylindrical body 3 of the first embodiment. Further, since the electric wire 2 is sandwiched between the slit of the cap 16 and the slit of the cylindrical body 17, the electric wire 2 is held more stably than the holder of the first embodiment. Furthermore, cap 1
The lower end portion 16c of 6 is positioned below the lower edge 2a of the held electric wire 2, so that rainwater or the like can be prevented from flowing into the lower end portion 16c.
Since it flows down from c, it is possible to reduce the accumulation of rainwater and the like on the cap 16 in the slits 17a and 17b.

[0042]

Third Embodiment Still another embodiment will be described with reference to FIG.

The holder 18 shown in FIG. 5 differs from the holder 1 of the first embodiment in the method of attaching the U-shaped clamp 5 to the tubular body 3. That is, in the holder 1 of the first embodiment, the U-shaped clamp 5 is arranged so that the cylindrical body 3 and the support pillar are parallel to each other.
However, in this embodiment, the U-shaped clamp 5 is attached so that the cylindrical body 3 is substantially perpendicular to the support.

Become.

It is advantageous that the electric wire 2 is installed so that its wide surface is perpendicular to the ground, that is, as shown in FIG. 1, in terms of strength against bending when a bird stays. However, depending on the habit of the bird to be repelled, etc., it is advantageous to erection so that a wide surface is parallel to the ground as shown in FIG.
It can be installed using the holder 18 as shown in FIG.

[0046]

[Fourth Embodiment] Still another embodiment will be described with reference to FIG.

The holder 19 of this embodiment is different from the above-mentioned embodiment in that a plate body 20 is used instead of the cylindrical body 3 of the main body. Further, a cover 21 is attached to play the role of the cap 6.

The plate body 20 made of an insulating material is shown in FIG.
Slits 22a and 22b are provided as shown in FIG. The slits 22a and 22b divide the upper portion of the plate body 20 into side pieces 20a and 20b and a central piece 20c. The electric wire 2 is sandwiched so as to alternate with the side pieces 20a and 20b and the center piece 20c, and is attached to the slits 22a and 22b.

[0052]

[Embodiment 5] Next, regarding an embodiment of a tensioning tool for the electric wire 2,
This will be described with reference to FIG.

The tensioning tool 33 has a coil spring 23, one end of which is provided with a fixing means for the support, and the other end of which is provided with an insulator 25.

The fixing means is a U-shaped clamp 24 having the same shape as that used in the holder 1 or the like of the above-mentioned embodiment, and the coil spring 23 and the coil spring 23 via a metal fitting 26 in the shape of an eight. It is installed. By attaching via the metal fitting 26, the degree of freedom of rotation of the fixing means is increased, and the workability of attachment to the support 27 is improved.

The insulator 25 is fixed to a connecting fitting 28 attached to the side of the coil spring 23 opposite to the side where the fixing means 24 is attached. Insulator 25
The electric wire 2 is wound around the wire, one end of the electric wire 2 is connected to a power source, and the other end of the electric wire 2 is installed on the field side to be protected from birds.

The tensioning tool 33 thus constructed is used to install the end portion of the electric wire 2. When the electric wire 2 is erected, the coil spring 23 is extended toward the arrow 30, the U-shaped clamp 24 is pulled toward the column 27 side, and the U-shaped clamp 24 is attached to the column 27 with one touch.

[0057]

[Embodiment 6] Next, referring to FIG.
0 will be described with reference to FIG. The bird damage prevention device 34 of the present invention is composed of a grip bar 35 and an attachment 36.

The grip bar 35 has a plate-shaped plus-side conductor 38 on one side along the longitudinal direction of the core bar 37 made of an insulating material.
However, plate-shaped negative side conductors 39 are attached to the other side by rivets 42, respectively. The tip of the rivet 42 is opened inside the core rod 37, so that the plus side conductor 38 and the minus side conductor 39 are attached to the core rod 37. That is, the tip of the rivet 42 for attaching the positive side conductor 38 to the core rod 37 is
Of the rivet 42 for attaching the negative side conductor 39 to the core rod 37 does not protrude to the plus side conductor 38 side of the core rod 37. . The reason why the tip of the rivet 42 is not projected to the other side is that the positive side conductor 38 and the negative side conductor 39 are kept in an insulating state and sparks are not generated.

A plus terminal 43 is attached to the plus side conductor 38, and a minus terminal 44 is attached to the minus side conductor 39. Lead wires 45 and 46 for applying a high voltage are connected to the positive terminal 43 and the negative terminal 44, respectively. Since the lead wire is connected by tightening the butterfly nut 47, the lead wire can be easily connected and removed without using an instrument, and the labor for installing the bird damage prevention device 34 can be reduced. I am trying.

At both ends of the core rod 37, resin caps 40a and 40b are fitted together with the end of the plus side conductor 38 and the end of the minus side conductor. As a result, the ends of the plus-side conductor 38 and the minus-side conductor 39 are separated from the ends of the core rod 37 so that they are not opened. Further, a voltage of several thousand volts is applied to the bird damage prevention device 34, but by fitting the resin caps 40a and 40b, the end portion of the plus side conductor 38 and the minus side conductor 39 are separated from each other. It is possible to prevent the occurrence of sparks between them. Furthermore, the ends are not exposed to the weather.

The fitting 36 is a metal pipe, and the grip bar 35 and the fitting 36 are spacers 41 made of an insulating material.
Through a and 41b, they are joined at a substantially right angle to form a T-shape. Since the fixture 36 is made of metal and a high voltage is applied to the positive side conductor 38 and the negative side conductor 39, the positive side is joined through the spacers 41a and 41b made of an insulator. This is to secure a space that does not spark from the conductor 38 and the minus conductor 39 to the fixture 36.

The bird damage prevention device 34 thus configured
Is attached to the upper end of the column 27 as shown in FIG.
You can easily attach it just by fitting
In order to securely fix the support 27 to the support 27 and to fix the support 27 so as not to rotate, the screw 48 is tightened and fixed to the support 27.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, but can be implemented in various forms within the scope of the matters described in the claims. It can be changed.

For example, in the invention of the holder, the slit 4a and the slit 4b are provided on a straight line in the above embodiment, but they may be provided at an angle. The retainer may be used as a fulcrum for bending the electric wire 2 when the electric wire 2 is attached to a corner of the field where the electric wire 2 should be installed. However, if the slit is provided in the tubular body at an angle,
Can be gently bent and the stress can be relieved.

Further, as shown in FIG. 9 (a), it is possible to change the means for attaching to the column. The holder shown in FIG. 9A is replaced with the U-shaped clamp 5 which is a means for attaching the holder 1 shown in FIG.
Is provided, and the expanded diameter portion 3a is directly attached to the upper end portion of the column 27 by covering.

Similarly, the holder shown in FIG. 9 (b) is similar to that shown in FIG.
Instead of the U-shaped clamp of the illustrated holder 18, a pipe 34 as an attachment means is attached in a direction perpendicular to the tubular body 3 and the pipe 34 is covered on the upper end portion of the column 27.

Further, the cap, ring, and
The shape of the upper end of the cylindrical body is circular, and the shape is such that birds can be retained. Since the cap or the like is not energized, if the bird remains in the cap or the like, the bird cannot be effectively repelled. Therefore, the cap, the ring, and the upper end of the cylindrical body including the upper end of the column can be devised such that they are pointed.

[0068]

According to the present invention, it is possible to always maintain a uniform tension state of the electric wire, and to easily attach a holder of the bird and beast protective electric wire, hold the electric wire, and attach the electric tip. Therefore, there is an effect that the time and labor for installing the electric wire can be reduced.

Further, since the bird damage prevention device having the core rod is used, it is possible to repel large birds without considering the tension of the electric wire and the fear of cutting. Furthermore, the bird damage prevention device can be installed by simply fitting the attachment part to the end of the support column or the horizontal rod and fixing it with a screw, which has the effect of saving installation time and reducing labor.
