[0008] Here, the place where the flying bird may stop is defined as a ground wire stretched over a high-voltage power transmission tower, a support arm of the tower supporting the ground, power transmission and distribution lines, and a power pole. It refers to installed electric wires (distribution lines, etc.), other handrails outside buildings, laundry poles, and the like. As the fine wire for bird damage prevention, a thin wire made of vinylidene fluoride resin is usually used, but any other thin wire may be used. In the case of using at a location related to power transmission lines, it is preferable to use a material having an insulating property, and at other locations, a general wire, a rope, or the like may be used.

The tape measure body is similar to a general tape measure, and can be fed and unwound (taken up) freely. In the present invention, a difference from a normal tape measure is that a normal tape measure is used. There is a difference in that the tape measure is made of a measure having a width, whereas the tape measure is made of a thin line. And it is preferable that it is a form which can fix and stop a thin wire in the middle like a conventional tape measure in a tape measure main body. In addition, as a locking tool for locking the erection mounting member at a location where the flying bird may stop, a ring shape, a clip shape, and others,
Various forms can be used. In short, any form may be used as long as the leading end on the feeding side can be fixed.

In the case where the bird prevention device of the present invention is stretched above a ground line, the bird's prevention device is directly connected to the ground line.
Alternatively, the tape measure main body is attached via the mounting support, and the payout side of the bird harm-preventing thin wire is fed out to a predetermined position from the tape measure main body, and the tip is fixed to the erection mounting member attached to the ground wire. By doing so, a thin line for bird damage prevention can be stretched. If the bird harm prevention wire is cut in the middle due to the wind or the like after the installation, the bird harm prevention wire is in a state of being urged by the tape measure main body, and thus the tape measure is immediately used. It is wound up (unwound) around the main body.

[0011]

As apparent from the above description, according to the bird protection device of the present invention, the bird-prevention instrument has a tape-measure-like main body in which a bird-prevention thin wire is wound in a tape measure. Since the thin wire can be unwound from the tape measure main body and urged in the rewinding direction, it can be easily stretched and replaced. The harm prevention thin wire is wound around the tape-shaped main body portion, which has the effect of preventing a power transmission accident or the like.

Further, in the above invention, at the tip of the feeding side of the bird damage prevention thin wire, the bird damage prevention thin wire is locked to a bridge mounting member at a location where the flying bird may stop. According to the configuration provided with, the extension work can be easily performed. Further, according to the configuration in which the leading end of the feeding line of the bird harm prevention wire is wound around another tape measure main body portion, even if the bird harm prevention wire is cut in the middle, the bird harm prevention wire is cut off. Since the tape is wound around each of the tape measure main bodies from the cut portion, the power transmission accident and the like can be more effectively prevented. Further, according to the configuration in which the tape-shaped main body has the mounting support for mounting at a place where the flying bird may stop, there is an effect that the stretching operation can be easily performed. Furthermore, according to the configuration in which a place where a flying bird may stop is an overhead wire such as a ground wire of a high-voltage power transmission tower, or a support arm for installing an overhead wire, it can be used as a bird damage prevention instrument at various locations. Has an effect.

FIG. 1 is a perspective view of the bird harm prevention device, and FIG. 2 is an explanatory view of a state where the bird harm prevention device is stretched.

The bird harm prevention device of this embodiment is an embodiment in which it is installed above a ground line installed on a high-voltage power transmission tower, and is schematically shown in FIGS. In this manner, the tape measure main body 2 is formed by winding the bird damage preventing thin wire 1 so as to be able to be fed out and rewinded freely. As the fine wire 1 for bird damage prevention, a fine wire made of vinylidene fluoride resin is used, and its diameter is 0.5 mm to 2 mm.
mm is used. At the leading end 1a of the feeding-prevention thin wire 1 on the feeding side, there is provided a locking tool 5 which is engaged with the erection mounting member 4 mounted on the ground wire 3. The erection mounting member 4 is made of an elongated plate or a rod-like member, and has a lower end provided with a fixing member 6 which sandwiches the ground wire 3 and can be fixedly fastened with bolts and nuts. A clip-like member 7 is attached. As a result, the leading end 1a of the bird harm-preventing thin wire 1 drawn out from the tape measure main body 2 can be fixed at a position above the ground line 3 (parallel along the ground line). The length of the bird wire 1 for preventing bird damage is usually about 3 m to 5 m. This corresponds to the length conventionally stretched on the ground wire 3 in the high-voltage power transmission tower. This is because if the length is long, it is likely to be shaken by the wind or the like, and the parallel stretchability with the ground line 3 may not be maintained. In addition, in cases other than high-voltage transmission line towers, poles, and wires, 1
It is preferable to be about 0 m.

The tape measure main body 2 has the same configuration as a tape measure as a normal measuring instrument. The difference from the tape measure as a measuring instrument is that the part to be fed out is a strip-shaped measure, whereas the one according to the present embodiment is the above-described bird damage preventing thin wire 1. This tape measure body 2
Has a structure in which the bird's harm prevention thin wire 1 can be always rewound around its center shaft 10 by an urging spring 11. This configuration also uses the same configuration as a generally known tape measure. That is, it is only necessary that the bird wire 1 for preventing bird damage can be rewound. The tape-shaped main body 2 is provided with a hole 9 at its tip for feeding out the bird harm-preventing thin wire 1, and has a mounting support 8 for fixing the tape-shaped main body 2 to the ground wire 3. The mounting support 8 has a fixture 12 that can be fixed by bolts and nuts. The tape measure main body 2 and the mounting support 8 may be joined in advance or may be fixed later.

In the apparatus for preventing bird harm according to this embodiment, the tape-shaped main body 2 is attached to the ground wire 3 via a mounting member 4 and a mounting support 8 at a predetermined interval.
Of the thin wire 1 for preventing bird damage is pulled out from the tape measure body 2 to pull out the thin wire 1 for preventing bird damage, and the locking tool 5 for the thin wire 1 for preventing bird damage is installed. By fixing to the clip-like member 7 of the mounting member 4, the bird damage preventing thin wire 1 can be stretched in parallel with the ground wire 3.

When the bird damage preventing thin wire 1 is cut in the middle due to the influence of wind or the like after being stretched, the bird damage preventing thin wire 1 is urged to the tape measure body 2 by the spring 11. In the state, the tape-shaped main body 2
It is wound up. When removing this bird harm prevention device,
The bird's harm prevention thin wire 1 is automatically wound around the tape measure body 2 by removing the locking member 5 of the bird harm prevention wire 1 from the clip-like member 7 of the erection mounting member 4. Can be replaced or exchanged.

It should be noted that the present invention is not limited to the above-described embodiment, but may be variously modified. For example, a configuration as shown in FIGS. In the bird harm prevention device having this configuration, two tape measure bodies 2 are paired, and one end of one bird harm prevention thin wire 1 is automatically wound around one tape measure body 2. It is wound so that it can be rewound, and the other end is wound so that it can be automatically rewound to the other tape measure main body 2. In other words, in the above-described embodiment, the distal end side 1a of the bird harm-preventing thin wire 1 is configured to be wound around another tape measure main body 2 that forms a pair. And
In both the tape measure bodies 2, the bird harm-preventing thin wire 1 is urged by a spring or the like so as to be wound around the respective tape measure bodies 2. When this bird harm prevention device is attached to the ground line 3, the form shown in FIG. 4 is obtained. In this configuration, when the bird damage preventing thin wire 1 is cut in the middle, the bird wire for preventing bird damage is wound around the tape measure main bodies 2 and 2 by the urging force. It is possible to eliminate the danger that 1 will hang down.

Further, in each of the above-described embodiments, the bird harm prevention device is described as being attached to the ground line 3, but may be attached to a wire supporting arm in a high-voltage transmission line tower or the like. In addition to the ground wire, it can be attached to transmission lines in high-voltage transmission towers, distribution lines in utility poles, wire support arms for utility poles, towers, and also to building handrails and clothes poles.
