図３に示す鉄塔１０の鉄塔本体１４に設けられるアーム１５の先端には、図４（ａ）に示すように、被固定材５が架設されており、この被固定材５に、例えば、ボルトにより固定されるがいし固定材７ａを介してがいし６ａ（「支持がいし」、あるいは、「長幹がいし」ともいう）が鉛直下方側に向って突設され、このがいし６ａの下端にがいし固定材７ｂ及び送電線固定具８を介して送電線９が吊下げ保持されている。 Here, with reference to FIGS. 3 and 4, a method of using the bird harm prevention tool 1 according to the present embodiment will be described.
The bird harm prevention device 1 according to the present embodiment is attached to the vicinity of the tip of the arm that supports the power transmission line mainly in the steel tower or the telephone pole that mainly supports the power transmission line, such as birds to the tip of the arm. This is to prevent flying and nesting by birds. In this embodiment, the main purpose is to prevent birds from flying and nesting to the tip of the arm of a steel tower or telephone pole. However, small animals other than birds (such as mice and flying squirrels) are also prevented from entering. It is an obstacle.
FIG. 3 is a side view showing an example of a steel tower to which the bird harm prevention tool according to the embodiment of the present invention is attached. Moreover, Fig.4 (a) is a side view which shows the use condition of the bird harm prevention tool which concerns on embodiment of this invention, (b) is an AA arrow directional cross-sectional view in Fig.4 (a). is there. The same parts as those described in FIGS. 1 and 2 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 3, when a transmission line (not shown in FIG. 3) is installed at the tip of an arm 15 extending from the tower main body 14 of the tower 10 standing on the ground 16, the tower 10 and the transmission line In order to insulate the power transmission line, the power transmission line is fixed to the steel tower 10 through an insulator which is an insulating material. FIG. 4A shows a state viewed from the direction indicated by the symbol P in FIG.
As shown in FIG. 4A, a fixed material 5 is installed at the tip of the arm 15 provided on the tower main body 14 of the steel tower 10 shown in FIG. The insulator 6a (also called “support insulator” or “long trunk insulator”) is protruded vertically downward through the insulator fixing member 7a, and the insulator fixing member 7b is formed at the lower end of the insulator 6a. The transmission line 9 is suspended and held via the transmission line fixture 8.

図４（ａ）に示すような送電線９の固定構造において、がいし６ａを固定するがいし固定材７ａの上面は平坦であり、この形状が鳥類が止まる際の足場として、あるいは、鳥類の営巣場所として特に適している。そして、このがいし固定材７ａ上に鳥類が営巣した場合、営巣材やそこで羽化した雛等が落下して、がいし６ａの直下に保持される送電線９に接触して接触事故が発生するケースが絶えなかった。
このような事情に鑑み、発明者らは鋭意研究の結果、がいし固定材７ａ上を本実施の形態に係る鳥害防止具１により被覆して、飛来した鳥の足場になり難くするとともに、がいし固定材７ａ上への営巣材の載置を困難にすることで、送電線９と、鳥類を含む生体や営巣材との接触事故を好適に防止できることを見出した。
より具体的には、先の図１，２に示すような形態を有する本実施の形態に係る鳥害防止具１のカバー部２により、図４（ａ）に示すように、がいし固定材７ａの上面を被覆することで、鳥類を含む生体を着地しづらくするとともに、がいし固定材７ａ上への営巣材を含む物体の載置をできなくすることに成功した。 In the structure for fixing the transmission line 9 as shown in FIG. 4 (a), the upper surface of the insulator fixing material 7a for fixing the insulator 6a is flat, and this shape serves as a scaffold when the birds stop, or the nesting place for the birds Particularly suitable as. And when birds nest on this insulator fixing material 7a, the nesting material and the chicks that emerged there fall down and contact the power transmission line 9 held directly under the insulator 6a, causing a contact accident. It did not end.
In view of such circumstances, as a result of diligent research, the inventors have covered the insulator fixing material 7a with the bird damage prevention device 1 according to the present embodiment, making it difficult to become a scaffold for flying birds, and using an insulator. It has been found that by making it difficult to place the nesting material on the fixing material 7a, a contact accident between the power transmission line 9 and a living body or nesting material including birds can be suitably prevented.
More specifically, as shown in FIG. 4 (a), the insulator fixing material 7a is formed by the cover part 2 of the bird harm prevention tool 1 according to the present embodiment having the form shown in FIGS. By covering the upper surface of the body, it was difficult to land a living body including birds, and succeeded in making it impossible to place an object including a nesting material on the insulator fixing material 7a.

つまり、本実施の形態に係る鳥害防止具１におけるカバー部２上に、万一、鳥類等の生体が着地しようとしたり、営巣材を載置した場合は、カバー部２の外形が鉛直上方に突状に湾曲形状していることにより、生体自体や載置物をカバー部２から滑落させて排除することができる。
この場合、図４（ａ），（ｂ）に示すように、鉛直方向において、本実施の形態に係る鳥害防止具１を構成するカバー部２の稜線２ｄの伸長方向と送電線９の伸長方向を一致させるとともに、カバー部２の湾曲辺２ａを、カバー部２の突面２ｆ側に緩やかに反らせておくことで、カバー部２上に載ったり又は落下してきた物体が、カバー部２の湾曲辺２ａ側から滑落するのを好適に防止することができる。
つまり、がいし固定材７ａを被覆するカバー部２上に、生体を含む物体が載ったり又は落下した場合、この物体はカバー部２の湾曲形状に沿って端辺２ｂに向って滑落するのであるが、このとき、湾曲辺２ａは突面２ｆ側に緩やかに反っているので、滑落する物体は湾曲辺２ａからは落下せず、必ずカバー部２の端辺２ｂから落下することになる。
従って、本実施の形態に係る鳥害防止具１によれば、がいし固定材７ａ上に載ったり又は落下した物体が、送電線９上に落下するのを確実に防止できるので、送電線９と、生体を含む物体との接触事故の発生を防止できるのである。 That is, if a living body such as a bird or the like tries to land or a nesting material is placed on the cover part 2 in the bird harm prevention tool 1 according to the present embodiment, the outer shape of the cover part 2 is vertically upward. In this way, the living body itself and the mounted object can be slid down from the cover portion 2 and eliminated.
In this case, as shown in FIGS. 4 (a) and 4 (b), in the vertical direction, the extension direction of the ridge line 2d of the cover portion 2 constituting the bird harm prevention tool 1 according to the present embodiment and the extension of the power transmission line 9 are shown. While the direction is matched and the curved side 2a of the cover part 2 is gently bent toward the projecting surface 2f side of the cover part 2, an object that has been placed on or dropped from the cover part 2 can be It is possible to suitably prevent sliding from the curved side 2a side.
That is, when an object including a living body is placed on or falls on the cover portion 2 that covers the insulator fixing material 7a, the object slides toward the edge 2b along the curved shape of the cover portion 2. At this time, since the curved side 2a gently warps toward the projecting surface 2f, the sliding object does not fall from the curved side 2a but always falls from the end side 2b of the cover portion 2.
Therefore, according to the bird damage prevention tool 1 according to the present embodiment, it is possible to reliably prevent an object placed on the insulator fixing material 7a or dropped from falling on the power transmission line 9, so that It is possible to prevent the occurrence of a contact accident with an object including a living body.

さらに、本実施の形態に係る鳥害防止具１においては、図１、図２、図４（ａ）にも示すように、カバー部２の４つの角２ｃを、その突面２ｆ側に、その湾曲辺２ａ中央よりも大きく反らせておいてもよい。
この場合、カバー部２上に載ったり又は落下した物体が、カバー部２上を滑落する際の勢いで、カバー部２の角２ｃ近傍において湾曲辺２ａに形成される反りを越えて送電線９上に落下するのを防止できる。
つまり、カバー部２における角２ｃ近傍の大きな反りが堤防の役割をして、湾曲辺２ａ側に物体が落下するのを防止できる。
この結果、カバー部２の湾曲辺２ａからの物体の落下を一層確実に防止でき、これにより、送電線９と生体を含む物体との接触事故を一層確実に低減できる。 Furthermore, in the bird harm prevention tool 1 according to the present embodiment, as shown in FIGS. 1, 2, and 4A, the four corners 2c of the cover portion 2 are arranged on the projecting surface 2f side. It may be warped larger than the center of the curved side 2a.
In this case, the power line 9 exceeds the warp formed on the curved side 2a in the vicinity of the corner 2c of the cover part 2 due to the moment when an object that has fallen on or dropped on the cover part 2 slides on the cover part 2. It can prevent falling down.
That is, it is possible to prevent the object from falling to the curved side 2a side by a large warp in the vicinity of the corner 2c in the cover portion 2 serving as a bank.
As a result, the fall of the object from the curved side 2a of the cover part 2 can be prevented more reliably, and thereby contact accidents between the power transmission line 9 and the object including the living body can be more reliably reduced.

また、本実施の形態に係る鳥害防止具１においては、図１、図２、図４（ｂ）に示すように、カバー部２の端辺２ｂを、カバー部２の突面２ｆ側に緩やかに反らせておいてもよい。
この場合、カバー部２上に載ろうとした又は落下した物体が、カバー部２の湾曲面上を滑落して端辺２ｂから落下する際に、図４（ｂ）にも矢印で示すように、カバー部２から離れる方向に（カバー部２の端辺２ｂから外側に）付勢して落下させることができる。これにより、カバー部２上を滑落して落下する物体が、カバー部２の鉛直下方に配設される送電線９に（図４（ａ），（ｂ）を参照）接触するあるいは引っ掛かるリスクを一層低減することができる。 Moreover, in the bird damage prevention tool 1 according to the present embodiment, as shown in FIGS. 1, 2, and 4 (b), the end 2 b of the cover 2 is placed on the projecting surface 2 f side of the cover 2. You may warp gently.
In this case, when an object about to fall on or fall on the cover portion 2 slides down on the curved surface of the cover portion 2 and falls from the end 2b, as shown by an arrow in FIG. It can be urged and dropped in a direction away from the cover portion 2 (outward from the end side 2b of the cover portion 2). As a result, there is a risk that an object that slides and falls on the cover part 2 comes into contact with or gets caught by the power transmission line 9 arranged below the cover part 2 (see FIGS. 4A and 4B). Further reduction can be achieved.

ここで、図４（ｂ）を参照しながら、被固定材５への本実施の形態に係る鳥害防止具１の取り付け方法について更に説明を加える。
図４（ｂ）に示すように、本実施の形態に係る鳥害防止具１は、例えば、カバー部２の湾曲内側面側に、稜線２ｄ方向と交差する向きに、平板状の補強部材２ｅを少なくとも１箇所設けておき、この補強部材２ｅに、例えば、羽子板ボルト状の支持部３を、例えば、ボルト等により、又は、溶接により固定してもよい。
この場合、例えば、図４（ｂ）に示すように、補強部材２ｅに複数個のボルト孔から成る位置決定孔１３を稜線２ｄ方向、すなわち送電線９の伸長方向と直角の方向に設けておいてもよい。これにより、がいし固定材７ａ上をカバー部２で確実に被覆することができるよう、支持部３の取り付け位置を適宜変更できるという効果を有する。
なお、カバー部２の補強部材２ｅにおいて、支持部３の取付け位置を変更可能にする手段は、必ずしも上述のような位置決定孔１３を設ける方法に限定される必要はなく、例えば、支持部３の固定具４に接続されない側の端部に挟持具を設けておき、平板状の補強部材２ｅの下端をスライド可能に挟持できるよう構成してもよい。すなわち、被覆対象である、例えば、がいし固定材７ａ上におけるカバー部２の相対位置を変更可能に構成されるものであればどのような構造を用いてもよい。 Here, with reference to FIG. 4 (b), a further description will be given of a method for attaching the bird harm prevention tool 1 according to the present embodiment to the material to be fixed 5.
As shown in FIG. 4 (b), the bird damage prevention device 1 according to the present embodiment has, for example, a flat reinforcing member 2e on the curved inner surface side of the cover portion 2 in a direction crossing the ridgeline 2d direction. At least one place may be provided, and for example, the support member 3 in the form of a battledore bolt may be fixed to the reinforcing member 2e by, for example, a bolt or by welding.
In this case, for example, as shown in FIG. 4B, the reinforcing member 2e is provided with position determining holes 13 made of a plurality of bolt holes in the ridgeline 2d direction, that is, in the direction perpendicular to the extending direction of the power transmission line 9. May be. Thereby, it has the effect that the attachment position of the support part 3 can be changed suitably so that the insulator fixing material 7a can be reliably coat | covered with the cover part 2. FIG.
In addition, in the reinforcing member 2e of the cover part 2, the means for making it possible to change the mounting position of the support part 3 is not necessarily limited to the method of providing the position determination hole 13 as described above. A holding tool may be provided at an end of the side not connected to the fixing tool 4 so that the lower end of the flat reinforcing member 2e can be slidably held. That is, any structure may be used as long as it is configured to change the relative position of the cover portion 2 on the insulator fixing material 7a, which is a covering target.

さらに、特に図示しないが、本実施の形態に係る鳥害防止具１における支持部３の棒状部分の少なくとも一部又は全部をコイルバネ等の弾性体に置換し、カバー部２上に荷重が作用した際に、カバー部２を復元可能に傾動させるよう構成してもよい。
この場合、カバー部２上に荷重が作用した際に、カバー部２の荷重が作用した位置が沈み込むなどして傾動することで、カバー部２上にある生体を含む物体の滑落を促進することができる。
より具体的には、例えば、カバー部２上の降雪があった際に、カバー部２は雪の重みで傾動して、雪をカバー部２の上面から好適に滑落させることができる。また、例えば、カバー部２上に鳥類等が止まった場合も、その荷重によりカバー部２自体が傾動して、カバー部２上の鳥類等のバランスを崩させてカバー部２上から鳥類等を排除できる。このとき、カバー部２に止まった鳥類等に対し、足場が不安定な不快感を与えて、以後、カバー部２上への飛来を忌避させる効果も期待できる。
加えて、傾動後にカバー部２を自然に復元するよう構成しておくことで、移動したカバー部２を元の位置に復元させて、覆設対象（例えば、がいし固定材７ａの上面など）を引き続き被覆して本来の作用，効果を継続して発揮させることができる。 Further, although not particularly illustrated, at least a part or all of the rod-shaped portion of the support portion 3 in the bird harm prevention tool 1 according to the present embodiment is replaced with an elastic body such as a coil spring, and a load acts on the cover portion 2. At this time, the cover 2 may be configured to tilt so as to be restored.
In this case, when a load acts on the cover part 2, the position where the load of the cover part 2 acts is tilted, for example, so that sliding of an object including a living body on the cover part 2 is promoted. be able to.
More specifically, for example, when there is snow on the cover part 2, the cover part 2 can be tilted by the weight of the snow, and the snow can be suitably slid down from the upper surface of the cover part 2. Further, for example, even when birds or the like stop on the cover part 2, the cover part 2 itself tilts due to the load, causing the birds or the like on the cover part 2 to be out of balance and removing the birds or the like from the cover part 2. Can be eliminated. At this time, it is also possible to expect an effect of giving an unpleasant feeling that the scaffolding is unstable to the birds and the like that have stopped on the cover part 2 and subsequently avoiding flying onto the cover part 2.
In addition, the cover part 2 is configured to be naturally restored after tilting, so that the moved cover part 2 is restored to the original position, and the covering object (for example, the upper surface of the insulator fixing material 7a) is restored. It can be continuously covered to continue to exhibit its original functions and effects.

また、本実施の形態に係る鳥害防止具１におけるカバー部２の材質は特に限定されないが、金属製又は合成樹脂製とすることで、成形を容易にするとともに、十分な耐久性や形状保持性も発揮させることができる。さらに、支持部３については強度等を考えると金属製とすることが望ましい。
なお、カバー部２の上面は、その表面における滑面性を高めるために可能な限り滑らかであることが望ましい。必要であれば、合成樹脂やその他の材質から成る塗膜をカバー部２の上面側に形成して滑面性を向上させたり、あるいは、カバー部２の表面に滑面性を高めるための表面加工を施してもよい。 Moreover, the material of the cover part 2 in the bird harm prevention tool 1 according to the present embodiment is not particularly limited. However, by using a metal or a synthetic resin, molding is facilitated and sufficient durability and shape retention are achieved. Sex can also be exhibited. Furthermore, it is desirable that the support portion 3 is made of metal in consideration of strength and the like.
In addition, as for the upper surface of the cover part 2, in order to improve the smoothness in the surface, it is desirable that it is as smooth as possible. If necessary, a surface made of synthetic resin or other material is formed on the upper surface side of the cover part 2 to improve the smoothness, or the surface of the cover part 2 to improve the smoothness. Processing may be performed.

従って、上述のような本実施の形態に係る鳥害防止具１によれば、送電線９上に配設される横架材や平板材上をカバー部２により被覆して、鳥類等の生体が飛来した際の足場になったり、鳥類等の営巣材の載置場所になるのを好適に防止できる。
また、万一、本実施の形態に係る鳥害防止具１のカバー部２上に鳥類等の生体を含む物体が（飛来し）載ったり又は落下した場合でも、カバー部２が湾曲形状を有し、かつ、その稜線と送電線の伸長方向を一致させて（略一致の概念も含む）取り付け、さらに、カバー部２の湾曲辺２ａに反りを形成しておくことで、カバー部２上にある物体がカバー部２の真下に配される送電線９に落下して接触事故を起こすリスクを大幅に低減できる。
従って、本実施の形態に係る鳥害防止具１を備えることで、鉄塔１０のアーム１５近傍における送電線９の安全性を高めることができる。 Therefore, according to the bird damage prevention device 1 according to the present embodiment as described above, the horizontal member or the flat member disposed on the power transmission line 9 is covered with the cover portion 2 so that a living body such as a bird can be obtained. Can be suitably prevented from becoming a scaffold when flying, or a place for placing nesting materials such as birds.
In addition, even if an object including a living body such as a bird is placed (falls) or falls on the cover part 2 of the bird harm prevention tool 1 according to the present embodiment, the cover part 2 has a curved shape. In addition, by attaching the ridge line and the extension direction of the power transmission line (including the concept of substantially coincidence), and further forming a warp on the curved side 2a of the cover part 2, The risk that a certain object falls on the power transmission line 9 arranged directly under the cover part 2 and causes a contact accident can be greatly reduced.
Therefore, the safety of the power transmission line 9 in the vicinity of the arm 15 of the steel tower 10 can be improved by providing the bird harm prevention tool 1 according to the present embodiment.

ここで図５を参照しながら本実施の形態に係る鳥害防止具１の他の取付け例について説明する。
図５は本発明の実施の形態に係る鳥害防止具の他の使用状態を示す側面図である。なお、図１乃至図４に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
本実施の形態に係る鳥害防止具１は、より大掛かりな送電線９の支持構造に対しても、例えば、必要に応じてカバー部２の湾曲辺２ａ側の幅を大きくする等により支障なく使用できる。
具体的には、図５に示すように、図中に破線で示す鉄塔１１（鉄塔１１の外形については図３を参照）から伸びるアーム（図示せず）の先端に配される被固定材５に、がいし６ｂを介して引張され、かつ、がいし固定材７ｃの鉛直下方側に垂下される縦長のがいし６ａを介して送電線固定具８により支持される送電線９の支持構造にも使用可能である。 Here, another example of attachment of the bird harm prevention tool 1 according to the present embodiment will be described with reference to FIG.
FIG. 5: is a side view which shows the other use condition of the bird damage prevention tool which concerns on embodiment of this invention. The same parts as those described in FIGS. 1 to 4 are denoted by the same reference numerals, and description of the configuration is omitted.
The bird harm prevention tool 1 according to the present embodiment can be used for a larger support structure of the power transmission line 9 by, for example, increasing the width on the curved side 2a side of the cover portion 2 as necessary. Can be used.
Specifically, as shown in FIG. 5, the fixed member 5 disposed at the tip of an arm (not shown) extending from a steel tower 11 (see FIG. 3 for the outer shape of the steel tower 11) indicated by a broken line in the figure. Moreover, it can be used also for the support structure of the transmission line 9 supported by the transmission line fixing tool 8 through the vertically long insulator 6a that is pulled through the insulator 6b and is suspended vertically below the insulator fixing member 7c. It is.

より詳細には、図５に示すように、送電線９は、がいし６ｂを複数個連結してなる連結体の端部に設けられる送電線引張具１２により鉄塔１１に引張支持されている。なお、がいし６ｂの連結体は、鉄塔１１から伸びるアーム（図示せず）の先端に配される被固定材５に取設されるがいし固定材７ｃの側面に固定されている。すなわち、図５に示す送電線９の支持構造において、がいし固定材７ｃは、がいし６ａ，６ｂを支持している。
上述の図５に示すような送電線９の支持構造においては、被固定材５の両端部に設けられるがいし固定材７ｃの上面が平面状になっており、鳥類等が飛来した際の足場に適しているだけでなく、営巣場所としても適しており、特に後者の場合、がいし固定材７ｃ上に形成された巣から落下した巣材や雛が送電線９に接触して接触事故を引き起こすケースが多々あった。 More specifically, as shown in FIG. 5, the power transmission line 9 is tension supported by the steel tower 11 by a power transmission line tensioning tool 12 provided at an end portion of a connection body formed by connecting a plurality of insulators 6 b. In addition, the connection body of the insulator 6b is fixed to the side surface of the insulator fixing member 7c installed on the fixing member 5 arranged at the tip of an arm (not shown) extending from the steel tower 11. That is, in the support structure of the power transmission line 9 shown in FIG. 5, the insulator fixing material 7c supports the insulators 6a and 6b.
In the support structure of the power transmission line 9 as shown in FIG. 5 described above, the upper surface of the insulator fixing material 7c provided at both ends of the material to be fixed 5 is flat, and serves as a scaffold when birds or the like fly. Not only suitable, but also suitable as a nesting place, especially in the latter case, a case where a nest or chick dropped from a nest formed on the insulator fixing material 7c contacts the power transmission line 9 to cause a contact accident There were many.

図５に示すような送電線９の支持構造の場合には、例えば、がいし固定材７ｃを支持する被固定材５に、例えば、固定具４を介して鳥害防止具１の支持部３を取設することで、本実施の形態に係る鳥害防止具１のカバー部２によりがいし固定材７ｃの上面を被覆することができる。この場合、固定材７ｃの上面への鳥類等を含む生体の着地や生体による物体の載置、物体の落地を好適に妨げることができる。
また、この時、図５に示すように、カバー部２の稜線２ｄ方向と送電線９の伸長方向を一致させておくことで、万一、がいし固定材７ｃを被覆するカバー部２上に生体を含む物体が（飛来し）載ったり又は落下した場合に、カバー部２を滑落して落下した物体が送電線９に接触するのを防止することができる。 In the case of the support structure of the power transmission line 9 as shown in FIG. 5, for example, the support portion 3 of the bird harm prevention tool 1 is attached to the fixed material 5 that supports the insulator fixing material 7 c, for example, via the fixing tool 4. By installing, the upper surface of the insulator fixing material 7c can be covered with the cover portion 2 of the bird harm prevention tool 1 according to the present embodiment. In this case, the landing of the living body including birds and the like on the upper surface of the fixing member 7c, the placement of the object by the living body, and the falling of the object can be suitably prevented.
At this time, as shown in FIG. 5, the ridge line 2d direction of the cover part 2 and the extending direction of the power transmission line 9 are made to coincide with each other so that the living body is covered on the cover part 2 covering the insulator fixing material 7c. When an object including the (flying) is placed or falls, it is possible to prevent the object that has fallen by sliding down the cover portion 2 from coming into contact with the power transmission line 9.

なお、本実施の形態に係る鳥害防止具１は、例えば、がいし６ａを固定するがいし固定材７ａやがいし固定材７ｃ上を被覆して、これらの上面側への生体を含む物体の着地や落地、載置を妨げるためのものであるが、カバー部２に取設される支持部３は、必ずしもがいし固定材７ａやがいし固定材７ｃに取設する必要はなく、カバー部２によりがいし固定材７ａの上面や、がいし固定材７ｃの上面を被覆できるのであれば、がいし固定材７ａ，７ｃの周囲にある架材等に鳥害防止具１の支持部３を固定してもよい。
また、本実施の形態に係る鳥害防止具１のカバー部２と、被覆対象である、例えば、がいし固定材７ａやがいし固定材７ｃの隙間に小鳥や小動物などが侵入したり、営巣する恐れがある場合は、支持部３の長さを短くしたり、湾曲辺２ａ下への侵入を防止するための被覆部材を配設する、あるいは、カバー部２の下面側に針状の突起物を設けて鳥類等の侵入を阻止するなどの方法がある。
さらに、本実施の形態においては、図３に示すような鉄塔１０から伸びるアーム１５の端部近傍における送電線９の支持構造に鳥害防止具１を取設する場合を例に挙げて説明しているが、図４，５に示すような送電線９の支持構造以外にも、例えば、電信柱に設けられる架材の端部における送電線の支持構造（簡易な構造のものを含む）にも支障なく使用可能である。 Note that the bird damage prevention device 1 according to the present embodiment covers, for example, the insulator fixing material 7a and the insulator fixing material 7c for fixing the insulator 6a, and landing of an object including a living body on these upper surfaces. Although it is intended to prevent falling and placing, the support part 3 installed on the cover part 2 does not necessarily need to be installed on the insulator fixing material 7a or the insulator fixing material 7c. As long as the upper surface of the material 7a and the upper surface of the insulator fixing material 7c can be covered, the support part 3 of the bird damage prevention tool 1 may be fixed to a frame around the insulator fixing materials 7a and 7c.
Further, there is a risk that a small bird, a small animal, etc. may invade or nest in the gap between the cover part 2 of the bird harm prevention device 1 according to the present embodiment and the covering target, for example, the insulator fixing material 7a or the insulator fixing material 7c. If there is, a covering member for shortening the length of the support part 3 or preventing the penetration under the curved side 2a is provided, or a needle-like protrusion is provided on the lower surface side of the cover part 2. There are methods such as setting up to prevent the invasion of birds and the like.
Furthermore, in this embodiment, the case where the bird damage prevention tool 1 is installed on the support structure of the transmission line 9 in the vicinity of the end of the arm 15 extending from the tower 10 as shown in FIG. 3 will be described as an example. However, in addition to the support structure for the power transmission line 9 as shown in FIGS. 4 and 5, for example, a support structure for a power transmission line (including a simple structure) at the end of a frame provided on a telegraph pole. Can be used without any problem.

以上説明したように本発明は、鉄塔又は電信柱のアームの先端近傍においてがいしを固定するがいし固定具上を被覆して、このがいし固定具上への鳥類の飛来や営巣材の載置を防止するとともに、万一、このカバー部上に鳥類などの生体を含む物体が（飛来し）載ったり又は落下した場合に、送電線上への物体の滑落を好適に防止できる鳥害防止具であり、送電設備に関する分野において利用可能である。   As described above, the present invention covers the insulator fixture that fixes the insulator in the vicinity of the tip of the arm of the steel tower or telephone pole, and prevents birds from flying on the insulator fixture and placing the nesting material. In addition, in the unlikely event that an object containing a living body such as birds is placed (falls) or falls on this cover part, it is a bird damage prevention tool that can suitably prevent the object from sliding down on the power transmission line, It can be used in the field related to power transmission equipment.
