Description

本発明は、鳥害防止具に関する。   The present invention relates to a bird harm prevention device.

電力線には、鳥害を防止するため、鳥害防止用のワイヤ（テグス）が張られることがある。この場合、ワイヤ架線用の鳥害防止具が電力線に取り付けられる（例えば、特許文献１）。この取り付けの際、電力線は、鳥害防止具が備える把持具に挟まれる。   In order to prevent bird damage, wires (tegs) for preventing bird damage may be provided on the power line. In this case, a bird harm prevention device for a wire overhead wire is attached to the power line (for example, Patent Document 1). At the time of this attachment, the power line is sandwiched between grippers provided in the bird harm prevention device.

特願２０１５−１５７１８８号Japanese Patent Application No. 2015-157188

ところで、図４（ａ）に示すように、鳥害防止具１００は、雪害対策等のため、電力線３００の外部表面上に、電力線３００の軸方向に沿った長尺な形状に形成された突起である軸方向突起３１０が設けられることがある。   By the way, as shown in FIG. 4A, the bird harm prevention device 100 is a protrusion formed on the outer surface of the power line 300 in a long shape along the axial direction of the power line 300 for snow damage prevention or the like. May be provided.

この場合、軸方向突起３１０が電力線３００と、鳥害防止具１００の把持具１１０との間に挟まれると、その挟まれた位置から軸方向突起３１０が脱しようとして、図４（ｂ） に示すように、鳥害防止具１００が傾いてしまう可能性があった。   In this case, when the axial projection 310 is sandwiched between the power line 300 and the gripper 110 of the bird harm prevention tool 100, the axial projection 310 tends to come off from the sandwiched position, as shown in FIG. As shown in the figure, there is a possibility that the bird harm prevention tool 100 is inclined.

本発明は、電力線の外部表面上に軸方向突起を有する電力線に取り付けても傾きにくい鳥害防止具を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a bird harm prevention device which is hardly inclined even when attached to a power line having an axial projection on an external surface of the power line.

本発明の鳥害防止具は、電力線に固定する電力線固定部と、電力線固定部から延設され、ワイヤを固定するワイヤ固定部と、を備える。
電力線固定部は、第１把持部と、第１把持部との間に電力線を挟む第２把持部とを備えている。 The bird harm prevention device of the present invention includes a power line fixing portion for fixing to a power line, and a wire fixing portion extending from the power line fixing portion and fixing a wire.
The power line fixing unit includes a first holding unit and a second holding unit that sandwiches the power line between the first holding unit and the first holding unit.

第１把持部又は第２把持部のうち少なくとも一方の電力線との当接面には、電力線の外部表面上に設けられた突起であって電力線の軸方向に沿って設けられた軸方向突起を嵌め合わせる又は遊びをつけて嵌め合わせることが可能な溝部が、電力線の軸周方向に沿った状態に並べて設けられている。   At least one of the first gripping portion and the second gripping portion, on the contact surface with the power line, is provided a projection provided on the outer surface of the power line, the axial projection provided along the axial direction of the power line. Grooves that can be fitted or fitted with play are provided side by side along the axial direction of the power line.

このようにすると、鳥害防止具を、軸方向突起を有する電力線に取り付けたとき、電力線の軸方向突起が鳥害防止具のいずれかの溝部に嵌ることとなる。そうすると、軸方向突起には、電力線を第１把持部と第２把持部とで挟んだときの力が加わらないので、軸方向突起には、挟まれた位置から脱しようとする力が働かない。   With this configuration, when the bird harm prevention tool is attached to the power line having the axial projection, the axial projection of the power line fits into one of the grooves of the bird harm prevention tool. Then, no force is exerted on the axial projection when the power line is sandwiched between the first gripping portion and the second gripping portion. .

したがって、本発明の鳥害防止具は、電力線の外部表面上に軸方向突起を有する電力線に取り付けても傾きにくい。
次に、本発明の鳥害防止具の溝部は、電力線の軸方向に沿った中央部分が狭く、両端側に向かって拡幅された形状に形成されていてもよい。電力線は、軸周りにひねられている場合がある。しかし、このような場合でも、溝部の形状を上記のような形状に形成すれば、軸方向突起が溝部に嵌る。したがって、本発明の鳥害防止具は、軸周りにひねられた電力線に取り付けても傾きにくい。 Therefore, the bird harm prevention device of the present invention is hardly inclined even when attached to a power line having an axial projection on the external surface of the power line.
Next, the groove portion of the bird harm prevention device of the present invention may be formed in a shape in which a central portion along the axial direction of the power line is narrow and widened toward both ends. The power line may be twisted about an axis. However, even in such a case, if the shape of the groove is formed as described above, the axial projection fits into the groove. Therefore, the bird harm prevention device of the present invention is hardly inclined even when attached to a power line twisted around the axis.

次に、本発明の鳥害防止具では、第１把持部又は第２把持部のうち少なくとも一方の電力線との当接面に、電力線の軸方向に沿った長尺な形状に形成された複数の長尺状突起を、電力線の軸周方向に沿って並べてもよい。この場合、溝部は、複数の長尺状突起によって、それぞれの長尺状突起の間に形成される。溝部は、第１把持部又は第２把持部の電力線との当接部分を削って設けてもよいが、このように、長尺状突起を設けて溝部を設けてもよい。   Next, in the bird harm prevention device of the present invention, at least one of the first gripping portion and the second gripping portion, which is in contact with the power line, has a plurality of elongated shapes formed along the axial direction of the power line. May be arranged along the axial direction of the power line. In this case, the groove is formed between each of the long protrusions by a plurality of long protrusions. The groove may be provided by cutting off the contact portion of the first gripping portion or the second gripping portion with the power line. In this manner, the groove may be provided by providing a long projection.

次に、本発明の鳥害防止具では、第１把持部又は第２把持部のうち少なくとも一方の電力線との当接面には、複数の小突起を複数列に並べて形成し、それぞれの小突起は、各列の間に溝部が形成されるように並べてもよい。溝部の形状は、必ずしも連続した形状ではなくてもよく、このように、複数の小突起により形成してもよい。   Next, in the bird harm prevention device of the present invention, a plurality of small projections are formed in a plurality of rows on a contact surface of at least one of the first grip portion and the second grip portion with the power line. The protrusions may be arranged such that a groove is formed between each row. The shape of the groove is not necessarily a continuous shape, and may be formed by a plurality of small projections.

以下に本発明の例示的な実施形態について図面を参照しながら説明する。
図１に示すように、本実施形態の鳥害防止具１は、電力線固定部２と締結具３とワイヤ固定部４とを備えている。 Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the bird harm prevention device 1 of the present embodiment includes a power line fixing unit 2, a fastener 3, and a wire fixing unit 4.

なお、以下の説明では、ワイヤ固定部４についてはどのような形態でもよいので、説明は省略する。
電力線固定部２は、鳥害防止具１を電力線３００に固定する部位である。電力線固定部２は、コの字状に形成された本体部２０と、この本体部２０が形成するコの字の開口部分を閉じる蓋部２１とを備えている。電力線固定部２は、蓋部２１を閉じると、本体部２０及び蓋部２１で形成する四角形状の枠で囲まれた電線固定空間２２を形成する。また、本体部２０の下側端部には、突起２９が設けられている。
蓋部２１は、本体部２０の上側端部（コの字の上側端部）に揺動可能に取り付けられ、遊端側には本体部２０の下側端部（コの字の下側端部）に係合させるための係合部２３が形成されている。この係合部２３は、電線固定空間２２の軸方向αの両端側に位置する両辺の一部を切り欠いたもので、蓋部２１は、蓋部２１を本体部２０に対して閉じたときに係合部２３を突起２９に係合させることで本体部２０に固定される。 In the following description, the wire fixing portion 4 may be in any form, and a description thereof will be omitted.
The power line fixing part 2 is a part for fixing the bird harm prevention device 1 to the power line 300. The power line fixing portion 2 includes a main body portion 20 formed in a U-shape, and a lid portion 21 for closing an opening portion of the U-shape formed by the main body portion 20. When the lid 21 is closed, the power line fixing unit 2 forms an electric wire fixing space 22 surrounded by a rectangular frame formed by the main body 20 and the lid 21. A projection 29 is provided at a lower end of the main body 20.
The lid portion 21 is swingably attached to an upper end portion (upper end portion of a U-shape) of the main body portion 20 and has a lower end portion (lower end portion of the U-shape) at the free end side. ) Is formed. The engaging portion 23 is formed by cutting out both sides located at both ends in the axial direction α of the electric wire fixing space 22, and the lid 21 is closed when the lid 21 is closed with respect to the main body 20. Then, the engaging portion 23 is engaged with the projection 29 to be fixed to the main body 20.

本体部２０のうち、コの字の上辺部分を第１把持部２４と呼ぶ。第１把持部２４は、電線固定空間２２を形成する側の面に、上方に向かって凹んだ三角形状の第１窪部２４０が設けられている。この第１窪部２４０は、軸方向αに沿った断面で見た形状が上方に向かって凹んだ三角形状に形成されている。そして、第１窪部２４０には、図２（ａ）に示すように、下方から見たときに、第１窪部２４０が形成する三角形の頂点が軸方向αに沿って連続する連続線βを挟んで左右対称に配置され、かつ、連続線βに垂直な方向に沿って等間隔に並べられた複数の長尺状突起２５が形成されている。これら長尺状突起２５は、下方から見ると、軸方向αに沿って細長い形状であって、軸方向αに沿って長い対角線を有する菱形形状に形成されている。   The upper side of the U-shape of the main body 20 is referred to as a first grip 24. The first grip portion 24 is provided with a first concave portion 240 having a triangular shape that is recessed upward on a surface on the side where the electric wire fixing space 22 is formed. The first recessed part 240 is formed in a triangular shape in which the shape as viewed in a cross section along the axial direction α is concave upward. As shown in FIG. 2A, the first concave portion 240 has a continuous line β in which the vertices of a triangle formed by the first concave portion 240 are continuous along the axial direction α when viewed from below. And a plurality of elongated projections 25 are arranged symmetrically with respect to the left and right and arranged at equal intervals along a direction perpendicular to the continuous line β. These elongated projections 25 are elongated in the axial direction α when viewed from below, and are formed in a rhombus shape having a long diagonal line in the axial direction α.

このように長尺状突起２５を設けると、これら長尺状突起２５の間には、図２（ｂ）（ｃ）に示すように、電力線３００の外部表面上に設けられた軸方向突起３１０であって、電力線３００の軸方向に沿って設けられた軸方向突起３１０を、遊びをつけて嵌め合わせることが可能な溝部２６が形成される。また、これら長尺状突起２５は、上述したように並設すると、連続線βの両側で、電力線３００の接線方向に沿って並べて設けられることとなる。   When the elongated projections 25 are provided in this manner, between the elongated projections 25, as shown in FIGS. 2B and 2C, the axial projections 310 provided on the outer surface of the power line 300. In addition, the groove 26 is formed in which the axial projection 310 provided along the axial direction of the power line 300 can be fitted with play. Further, when these elongated projections 25 are juxtaposed as described above, they are arranged side by side along the tangential direction of the power line 300 on both sides of the continuous line β.

締結具３は、図１に示すように、電力線固定部２の本体部２０のうち、コの字の下辺部分の上方側に第２把持部３０、下方側にハンドル部３９を備えている。本体部２０のうち、コの字の下辺部分を、以下、基礎部２７とよぶ。   As shown in FIG. 1, the fastener 3 includes a second grip 30 on the lower side of the U-shape of the main body 20 of the power line fixing section 2 and a handle 39 on the lower side. The lower side of the U-shape of the main body 20 is hereinafter referred to as a base 27.

第２把持部３０は、本体部２０に対し、電線固定空間２２内を上下方向に移動可能に取り付けられている。この第２把持部３０の上方側の面には、下方に向かって凹んだ三角形上の第２窪部３００が設けられている。この第２窪部３００は、第１窪部２４０に対向する位置に設けられている。   The second grip 30 is attached to the main body 20 so as to be movable in the vertical direction in the wire fixing space 22. On the upper surface of the second grip portion 30, a triangular second concave portion 300 that is concave downward is provided. The second recess 300 is provided at a position facing the first recess 240.

ハンドル部３９は、基礎部２７に対し回転可能に取り付けられている。第２把持部３０は、このハンドル部３９を回転させると、電線固定空間２２内で上下に移動する。そして、所定位置で回転を止めると、その位置で固定され、ハンドル部３９を回転させることによって電線固定空間２２で移動した第２把持部３０も、その移動した後の位置で固定される。   The handle 39 is rotatably attached to the base 27. When the handle portion 39 is rotated, the second grip portion 30 moves up and down in the electric wire fixing space 22. Then, when the rotation is stopped at a predetermined position, the second grip portion 30 fixed at that position and moved in the wire fixing space 22 by rotating the handle portion 39 is also fixed at the position after the movement.

本実施形態の鳥害防止具１を電力線３００に固定する場合は、次のように取り付け、テグスを電力線３００上に張る。
（１）作業者は、ハンドル部３９を回転させて、第２把持部３０を下端まで下げる。 When fixing the bird harm prevention device 1 of the present embodiment to the power line 300, the bird harm prevention device 1 is attached as follows, and the grease is stretched on the power line 300.
(1) The operator rotates the handle 39 to lower the second grip 30 to the lower end.

（２）作業者は、鳥害防止具１が鉛直になるように、鳥害防止具１を電力線３００に取り付ける。本実施形態では、複数の溝部２６が形成されているので、電力線３００が軸周りにねじれていても、電力線３００の軸方向突起３１０が、いずれかの溝部２６に嵌る。
そうすると、鳥害防止具１は、傾きなく電力線３００に取り付けることができる。 (2) The worker attaches the bird harm prevention tool 1 to the power line 300 so that the bird harm prevention tool 1 becomes vertical. In the present embodiment, since the plurality of grooves 26 are formed, even when the power line 300 is twisted around the axis, the axial projection 310 of the power line 300 fits into one of the grooves 26.
Then, the bird harm prevention device 1 can be attached to the power line 300 without tilting.

（３）作業者は、蓋部２１を閉める。
（４）作業者は、ハンドル部３９を操作して第２把持部３０を上方に移動させ、電力線３００を第１把持部２４と第２把持部３０との間に挟む。 (3) The worker closes the lid 21.
(4) The operator operates the handle 39 to move the second grip 30 upward, and sandwiches the power line 300 between the first grip 24 and the second grip 30.

（５）作業者は、電力線３００に鳥害防止具１を取り付け終えたら、テグスをワイヤ固定部４に固定しながら、電力線３００上に張る。
以上説明した鳥害防止具１の特徴的な作用効果について説明する。 (5) After finishing attaching the bird harm prevention device 1 to the power line 300, the worker stretches the grease on the power line 300 while fixing the tex to the wire fixing portion 4.
The characteristic operation and effect of the bird harm prevention device 1 described above will be described.

本実施形態の鳥害防止具１は、雪害対策用の電力線３００のように、軸方向突起３１０を有する電力線３００に取り付けたとき、電力線３００の軸方向突起３１０が鳥害防止具１のいずれかの溝部２６に嵌ることとなる。そうすると、電力線３００の軸方向突起３１０には、電力線３００を第１把持部２４と第２把持部３０とで挟んだときの力が加わらないので、電力線３００の軸方向突起３１０には、挟まれた位置から脱しようとする力が働かない。   When the bird harm prevention device 1 of the present embodiment is attached to the power line 300 having the axial protrusion 310 like the power line 300 for snow damage countermeasures, the axial protrusion 310 of the power line 300 is attached to any one of the bird harm prevention device 1. In the groove 26 of FIG. Then, the force generated when the power line 300 is sandwiched between the first grip 24 and the second grip 30 is not applied to the axial projection 310 of the power line 300, and thus the axial projection 310 of the power line 300 is sandwiched between the axial projection 310 of the power line 300. The force to get out of the position does not work.

したがって、本実施形態の鳥害防止具１は、電力線３００の外部表面上に軸方向突起３１０を有する電力線３００に取り付けても傾きにくい。
次に、本実施形態の鳥害防止具１の溝部２６は、細長い菱形形状に形成されているので、電力線３００が軸周りにひねられ、電力線３００の周りに螺旋形状に巻かれたような状態になっても、電力線３００の軸方向突起３１０が溝部２６に嵌る。したがって、本実施形態の鳥害防止具１は、軸周りにひねられた電力線３００に取り付けても傾きにくい。 Therefore, the bird harm prevention device 1 of the present embodiment is hardly inclined even when attached to the power line 300 having the axial projection 310 on the outer surface of the power line 300.
Next, since the groove 26 of the bird harm prevention device 1 of the present embodiment is formed in an elongated rhombus shape, the power line 300 is twisted around the axis and spirally wound around the power line 300. , The axial projection 310 of the power line 300 fits into the groove 26. Therefore, the bird harm prevention device 1 of the present embodiment is hardly inclined even when attached to the power line 300 twisted around the axis.

以上、実施形態について説明したが、特許請求の範囲に記載された発明は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。

In this case, the first recess 240 may be formed in a shape along the circumference of the power line 300.

（２）上記実施形態では、長尺状突起２５を複数設けて溝部２６を形成したが、第１把持部２４を削って、長尺状突起２５を設けることなく、溝部２６を第１把持部２４に設けてもよい。   (2) In the above-described embodiment, the groove 26 is formed by providing a plurality of elongated protrusions 25. However, the first grip 24 is cut off, and the groove 26 is formed by the first grip 25 without providing the elongated protrusion 25. 24.

（３）上記実施形態では、菱形の長尺状突起２５を用いて溝部２６を形成したが、これに限るものではない。例えば、図３に示すように、溝部２６は、電力線３００との当接面に、複数の小突起２８を複数列に並べて形成してもよい。   (3) In the above embodiment, the groove 26 is formed by using the long protrusion 25 of a rhombus, but the present invention is not limited to this. For example, as shown in FIG. 3, the groove 26 may be formed by arranging a plurality of small protrusions 28 in a plurality of rows on a contact surface with the power line 300.

（４）上記実施形態では、溝部２６を菱形形状に形成したが、溝部２６は、電力線３００の軸方向に沿った中央部分が狭く、両端側に向かって拡幅された形状に形成されていればよく、菱形は、その一形態である。   (4) In the above embodiment, the groove 26 is formed in a rhombic shape. However, the groove 26 may be formed in a shape in which the central portion along the axial direction of the power line 300 is narrow and widened toward both ends. Often, a diamond is one form.

（５）上記実施形態では、溝部２６を第１把持部２４に設けたが、第２把持部３０に設けてもよい。また、溝部２６は、第１把持部２４と第２把持部３０に設けてもよい。
（６）上記実施形態では、溝部２６は、電力線３００の軸方向突起３１０を、遊びをもって嵌め合わせる大きさの溝としたが、電力線３００の軸方向突起３１０が遊びなく嵌る大きさに形成してもよい。 (5) In the above embodiment, the groove 26 is provided on the first grip 24, but may be provided on the second grip 30. Further, the groove 26 may be provided in the first grip 24 and the second grip 30.
(6) In the above-described embodiment, the groove 26 is a groove having a size such that the axial protrusion 310 of the power line 300 fits with play. However, the groove 26 is formed to have such a size that the axial protrusion 310 of the power line 300 fits without play. Is also good.
