Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird harm prevention device and a bird harm prevention device for preventing crows from nesting on a steel tower or the like.

[0002]

[Prior Art] In order to protect yourself from external enemies such as snakes,
Nests are built on high places such as on trees, but in recent years when forests have been cut down, nests are often made on steel towers that support power transmission lines, which has led to an increase in the number of electrical accidents caused by the attachment of nesting materials. ing.

FIG. 10 shows an example in which a crow nest is formed on a steel tower 40. As shown in the figure, a nest 43 is formed on a horizontal portion 45 of an arm 42 extending horizontally from a tower body 41 of the steel tower 40. Often.

[0004] In making nests, crows have the habit of forming dummy nests everywhere in addition to the nests actually used, and use disposable wires or metal clothing crests as nesting materials. Because of this,
If these many nests are left as they are, the nesting material may be separated from the nests by the wind or the like and may be caught or hit by the transmission line 46 to cause a short circuit accident.

[0005] Since nest building is generally performed around March, the nest is conventionally removed according to the nesting season. However, the work is performed at a high place, and power transmission is stopped during the work. Must.

For this reason, various countermeasures have been developed for preventing accidents caused by crows.

For example, there is a fence 44 mounted on the horizontal portion 45 of the arm 42 to prevent the crow from entering the tower 40. This mounting requires stopping the power transmission.

Therefore, without stopping the power transmission, the crows dislike the crows, singing the crows away with special sound waves, and installing various types of prevention tools such as simulated eyeballs, needles, and propellers on the horizontal part of the tower. To prevent nesting.

[0009]

However, these preventive devices have a problem in that they are costly. In particular, since wisdom has developed considerably in crows, there has been a problem in that if learning shows that these preventive devices are not dangerous, they become completely useless.

It is an object of the present invention to solve the above-mentioned problems and to provide a bird harm prevention apparatus and a bird mitigation device which can be inexpensively without stopping power transmission and which can surely prevent crow's nest formation.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a method for suspending a bird on a relatively horizontal part such as a steel tower where a crow passes therethrough. This constitutes a prevention device. The crow has the wisdom and feels the trick and does not lean on the tower.

Preferably, a plurality of the ring members are suspended at a predetermined interval from a relatively horizontal portion where the crow nests.
It is possible to more effectively prevent the crow from approaching the horizontal portion.

The bird harm prevention device constituting the bird harm prevention device includes a ring member formed of a synthetic resin thread,
One end is connected to the ring member via a return member, and the other end is detachably attached to a fixed portion above a relatively horizontal portion where the crow nests, and the ring member is attached above the horizontal portion. And a suspending thread member for suspending at a predetermined height.

The ring member is preferably formed of a synthetic resin thread so as to have an inside diameter that allows the nest of the crow to pass through.

Further, the hanging thread member is formed of a synthetic resin thread material, one end is connected to the ring member via a monkey ring, and the other end is detachably attached to the fixing portion. It is good to have a mounting member connected so that return is possible.

It is preferable that the length of the hanging string member is adjustable between a mounting member for detachably attaching to the fixing portion and the ring member.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 3, the bird harm prevention device 1 is formed by suspending a ring member 3 such as a steel tower 2 having a size such that the crow can pass over a relatively horizontal portion 5 where the crow nests. .

More specifically, as shown in FIGS. 3, 4 and 5, a plurality of ring members 3 are suspended at predetermined intervals from each other near the base end of each arm 4 and on the top 6 of the steel tower 2. Lower. At this time, the height of the ring member 3 is adjusted and suspended so that the head of the crow is located at the center of the ring member 3 when the crow stops at the horizontal portion 5.

The ring member 3 is formed by a thread made of a synthetic resin so as to have an inside diameter enough to allow the crow body to pass through. Specifically, the ring member 3 is made of nylon 3
A translucent fishing line equivalent to No. 0 is bent in an annular shape, and both ends of the fishing line are connected by a double sleeve 7. Ring member 3
Is formed to have a diameter of about 10 cm, and a monkey ring 8 as a return member is connected to the ring member 3.

The monkey ring 8 is connected to a hanging string member 9 described later to form a bird damage prevention device 11.

The suspension line member 9 is formed of a fishing line as a synthetic resin line. This fishing line is translucent equivalent to nylon 20.

The hanging string member 9 has one end (lower end) at the monkey ring 8.
And the other end (upper end) is detachably attached to a fixed portion of the steel tower 2 via an attachment 10 described later, and is connected more removably to the ring member 3. Have.

The hanging thread member 9 is provided with a length adjusting means 13.
And the length is adjustable between a mounting member 14 and a ring member 3 for detachably mounting to a fixed portion or the like of the steel tower 2.

More specifically, one end of the hanging string member 9 is inserted into a connecting ring 12 formed at one end of the monkey ring 8 and is folded back, and is connected to a lower portion of the hanging string member 9 by a double sleeve 7. ing. Further, a length adjusting means 13 is provided at the other end of the hanging thread member 9, and is connected to the mounting member 14 via the length adjusting means 13.

The length adjusting means 13 is formed by folding the upper part of the hanging string member 9 and slidably inserting the hanging string members 9 extending downward from the folded position into the double sleeve 15 for adjustment.

The length adjusting means 13 can adjust the length of the hanging string member 9 by sliding the hanging string member 9 within the adjusting double sleeve 15 and changing the folded length. Further, the length adjusting means 13 slides the double sleeve 15 for adjustment and makes the suspension thread member 9 bend tight by bringing it close to the folding position.
The adjusting double sleeve 15 can be stopped by utilizing the repulsive force of the above.

At the end of the hanging thread member 9 extending from the adjusting double sleeve 15, a single sleeve 1 for terminal treatment is attached.
6 and a double sleeve 15 for adjusting the thread end.
From falling off.

The mounting member 14 is a monkey ring with snaps. The monkey ring with a snap is generally sold as fishing gear, and a hook-shaped snap 17 is attached to one end of the monkey ring 8.
Are connected.

As shown in FIG. 1 and FIG.
Are connected to a fixture 10 attached to a fixed portion of the steel tower 2 or the like.

The mounting fixture 10 is a commercially available insulation lock 18.
Consists of The insulating lock 18 is wound and fixed around a steel frame material 23 or the like forming a metal arm or the like serving as a fixing portion, and is formed in a belt shape from a weather-resistant synthetic resin.

A locking portion 19 is formed at one end of the insulating lock 18 for inserting and locking the other end. Claws 21 projecting toward the center of the holes are formed in the insertion holes 20 formed in the locking portions 19, and receiving grooves 22 for engaging with the claws 21 are formed on one surface of the insulating lock 18 in the longitudinal direction. Is also formed.

The claw 21 and the receiving groove 22 engage with the insertion hole 2 when engaged.
Movement in the direction of insertion through 0 is allowed, and movement in the removal direction is restricted.

Then, the insulating lock 18 is connected to the steel frame material 23.
The other end is inserted through the locking portion 19 and pulled and pulled and fixed.

Next, the operation will be described.

In the case where the bird harm prevention device 1 is provided on the steel tower 2, as shown in FIGS. 1 and 3, a steel frame in the vicinity of the arm bar such as the arm bar hanging portion or the main member of the arm bar located above the horizontal portion 5 of the arm 4. The bird harm prevention tool 11 is attached to the material 23 via the attachment 10,
The ring member 3 is suspended near the horizontal portion 5.

More specifically, first, the steel frame member 23 near the arm is used.
Wrap the insulation lock 18 around the insulation lock 18
The other end is inserted through the locking portion 19 formed at one end of the, and pulled, tightened and fixed.

Next, the attachment member 1 is attached to the insulation lock 18.
When the snap 17 of No. 4 is engaged and the length of the hanging string member 9 is appropriately adjusted by the length adjusting means 13, the process is completed.

When the length of the hanging member 9 is to be reduced, the adjusting double sleeve 15 is once pulled down below the ring member 3. As a result, the adjusting double sleeve 15 approaches the ring member 3, the turning point is moved toward the ring member 3, and the ring member 3 is pulled up.

When the ring member 3 is positioned at a predetermined height, the adjusting double sleeve 15 is slid upward (toward the mounting member 14) so as not to move the single sleeve 16. As a result, the suspending thread member 9 is tightly bent, and the adjusting double sleeve 15 stops near the turning point due to the repulsive force of the suspending thread member 9.
Length can be easily adjusted.

When the length of the hanging member 9 is to be increased, the adjusting double sleeve 15 is once pulled down below the ring member 3 and the ring member 3 is pulled down. The adjusting double sleeve 15 is raised, and the ring member 3 is lowered.

When the ring member 3 is positioned at a predetermined height, the adjusting double sleeve 15 is slid upward so as not to move the single sleeve 16. Thereby, the length of the hanging string member 9 can be easily adjusted.

When the tower 2 is provided with the bird harm prevention device 11, the crow approaching the tower 2 will have the ring member 3 suspended from the tower 2.
Be cautious and feel danger.

That is, since the suspended ring member 3 has such a size that it can pass through the crow, it is possible to have a caution that it is a collar.
Is translucent, so you can be wary of tricks.

Moreover, since the ring member 3 is suspended by the hanging thread member 9 and swings irregularly and easily by wind or the like, the danger of the ring member 3 being caught on the neck can be sufficiently predicted as a crow. Can be recognized as dangerous.

In particular, for crows intending to nest on the horizontal portion 5 of the tower 2, the ring member 3 is located at the height of the head. When the nesting material is carried, the danger of the nesting material being caught can be predicted, so that a strong caution can be given and the nesting on the horizontal portion 5 can be abandoned.

As a result, no nest is formed in the vicinity of the horizontal portion 5 of the arm 4 having the ring member 3, and an accident due to a crow can be prevented.

The bird harm prevention device 11 should not be attached to the inside of the tower 41 as far as possible without hindrance. We will try to avoid disturbing the birds as much as possible and prevent harm to the birds while harmonizing with the natural world based on the idea of coexistence and coexistence.

Since the crow has an extremely high learning ability, if the preventive device 11 is always left attached, it becomes accustomed and the effect is lost. Since it is possible to attach the preventive device 11 only for a certain period of time from the time when the crow starts nesting activity, or it can be detachably attached to the steel tower 2, it is removed once after about 2 years from the installation, and a new one is installed. Can be replaced with something.

The removal of the bird harm prevention device 11 is performed by cutting the insulation lock 18 with a tool such as a nipper. Since the insulation lock 18 is formed of a synthetic resin, it can be easily cut, and the bird harm prevention tool 11 can be easily collected without stopping power transmission.

As described above, since only the ring member 3 large enough for the crow to pass through is hung on the relatively horizontal portion 5 where the crow nests, such as the steel tower 2, the power transmission can be easily performed without stopping the power transmission. It is possible to inexpensively prevent crow accidents.

The ring member 3 is connected to the horizontal portion 5 of the steel tower 2.
A horizontal part 5 where crows prefer to nest because they are hung nearby
Can keep the crow away.

The ring member 3 is formed of a translucent fishing line, and the hanging member 9 is formed of a translucent fishing line. Can be.

Then, since the ring member 3 is connected to the hanging string member 9 by the monkey ring 8, the ring member 3 can rotate freely, thereby making the crow more alarmed.

Further, since the ring member 3 is formed with a fishing line to a diameter of about 10 cm and the hanging line member 9 made of a fishing line is connected via a monkey ring 8, a bird damage prevention device 11 is formed. It can be made by assembling fishing gear,
The bird harm prevention tool 11 can be provided at low cost.

The attachment 10 is made of an insulation lock 18 wound around a steel frame 23 or the like, and the attachment member 14 for hanging the insulation lock 18 is connected to the hanging string member 9. 11 can be attached easily and without stopping power transmission.

The ring member 3 is formed of a fishing line equivalent to nylon No. 30, and the hanging line member 9 is formed of nylon 2
Since the suspension line member 9 is formed to be thinner than the ring member 3 by forming a fishing line equivalent to No. 0, the ring member 3 can be made to appear to be floating in the air, and a stronger caution is given to the crow. it can.

Further, since the bird harm prevention tool 11 is manufactured using only fishing line and extremely small metal fittings such as the monkey ring 8,
It is lightweight and can be dropped at a sufficiently low speed even if it falls, preventing damage to houses and pedestrians below. Further, since it is hardly visible from the ground, it is possible to prevent giving an illusion to a nearby inhabitant that an accident such as a spark has occurred.

Next, another embodiment will be described.

As shown in FIG. 6, the bird harm prevention device 24 described here is a modification of the above-mentioned attachment 10. There is no change in the bird harm prevention tool 11 (the ring member 3 and the hanging string member 9), and it is the same as that described above.

The mounting fixture 10 includes a pair of insulation locks 1.
8, 18 and a tension thread 25 stretched between the insulated locks 18, 18. The insulation lock 18 is the same as described above.

The tensioning thread 25 has a pair of snaps 17 for hooking on the insulation lock 18, and one of the snaps 17 is connected to the thread portion 27 via the length adjusting means 26.

The length adjusting means 26 is the same as the length adjusting means 13 of the hanging thread member 9, and can adjust the length of the thread between the snaps 17.

As shown in FIG. 7, the thread portion 27 has a plurality of loops 28 at appropriate intervals in the middle. Specifically, a plurality of fishing lines 29 are connected to form a line portion 27,
A hanging ring 28 is formed at a connection portion between the fishing lines 29.

Then, the plurality of ring members 3 are suspended in the shape of a noren by hanging the snap 17 of the hanging thread member 9 on each hanging ring 28.

In the case where the bird harm prevention tool 11 is provided on the steel tower 2, a pair of insulated locks 18, 18 are provided on the steel frame member 23 near the arm.
Are attached at appropriate intervals. Then, the snap 17 of the tension thread 25 is hung on each of the insulation locks 18, 18.

The length of the thread between the snaps 17 is adjusted by the length adjusting means 26, and the tension thread 25 is stretched between the insulated locks 18. Thereafter, the hanging ring 28 formed on the thread portion 27
Then, the snap 17 of the hanging thread member 9 is hooked, and the ring member 3 is hung.

By changing the mounting member 10 in this manner, a large number of ring members 3 can be easily mounted in a short time, and the number of the insulating locks 18 to be used can be reduced.

Further, the ring member 3 can be hung at an arbitrary position by stretching the tension string 25 between the different steel members 23, 23.

The mounting fixture is not limited to the one described above, and is shown in FIG.
As shown in FIG.
May be formed with a hole 31 for hooking.

As shown in FIG. 9, a clip 32 may be used.

When these magnets 30 and clips 32 are used, the magnets 30 and clips 32 may fall off from the steel tower 2, so that they should be small and light.

Needless to say, the bird harm prevention device may be suspended from a building other than the steel tower 2.
