Description

【０００１】
【発明の属する技術分野】
本発明は、例えば送電線鉄塔の構造材に取り付けられる電撃式鳥害防止装置に関する。
【０００２】
【従来の技術】
従来、この種の電撃式鳥害防止装置としては、例えば特許文献１に記載の装置のように、所定長さの留まり木状に形成された電極部材を鉄塔の横構造材（Ｌ型アングル材）に沿うように取り付けたものが知られている。即ち、前記電極部材は、絶縁体からなる支持棒部材に所定のピッチで一対の導電線がスパイラル状に巻き付けられたものであり、一方の導電線が電圧印加手段に接続されると共に、他方の導電線が鉄塔の横構造材にアース接続された構成になっている。そして、飛来した鳥（カラス、ハト等）が前記電極部材に留まって前記両導電線に同時に接触した際には、当該鳥の体内に低電圧の電流が流れるようにし、その際の電気的ショックで鳥を撃退すると共に、その電気的ショックの学習効果で二度と近付かせないようにして営巣防止を図るようにしていた。

【特許文献１】
特開２０００−１０２１５１公報（請求項１，２、図２，３）
【０００４】
【発明が解決しようとする課題】
ところが、前記特許文献１の電撃式鳥害防止装置の場合には、次のような問題があった。即ち、一般に、鳥害防止装置は送電線鉄塔のＬ型アングル材のような野外の構造材上に取り付けられるため、鳥の留まり部となる前記電極部材は風雨に晒されることになる。そのため、雨天時には前記電極部材における支持棒部材の周面に沿って雨水が流れ、その雨水の流れにより当該支持棒部材の周面に巻き付けられた両導電線間が導通することがあった。また、雨天時ではなくても寒冷時には前記支持棒部材の周面に結露が生じることがあり、そのような結露が起因となって前記両導電線間が導通することもあった。従って、本来は、電極部材上に留まった鳥に対し電気的ショックを与える目的で設けられた電圧印加手段（例えばバッテリ等）の電力が無駄に消費されることになると共に、ときには前記導通が不測の短絡事故を招来する可能性もあり得た。
【０００５】
本発明は、このような事情に鑑みなされたものであり、その主たる目的は、野外に設置された場合でも雨水や結露により電極部の両導電部間が導通することを防止でき、無駄な電力の浪費や不測の短絡事故の虞を回避できる電撃式鳥害防止装置を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、電撃式鳥害防止装置に係る請求項１に記載の発明は、鳥の飛来箇所に設置される装置本体を有し、当該装置本体には飛来した鳥が留まった際に当該鳥に対して電気的ショックを与える電極部が設けられた電撃式鳥害防止装置において、前記電極部は、前記装置本体の上部側で所定方向へ平行に延びる一対の導電部からなり、互いに隣り合う両導電部間に所定の空隙を形成するようにして設けられていることを特徴とする。
【０００７】
なお、本明細書において、導電部間に形成される「空隙」とは、互いに隣り合う両導電部間に介在して当該両導電部間を空間で分離する空間的な隔たりであって、それら両導電部よりも下方の空間域を含んで当該両導電部間に形成されるものをいう。
【０００８】
また、請求項２に記載の発明は、請求項１に記載の電撃式鳥害防止装置において、前記電極部は所定方向へ平行に延びる一対の導電部により構成されると共に、前記装置本体の上部側には装置本体の長さ方向へ平行に延びる一対の突片部が両突片部の互いに対向する先端同士の間に所定の空隙を形成するようにして突設され、各突片部の表面上に前記各導電部が各々露出するように設けられていることを特徴とする。
【０００９】
また、請求項３に記載の発明は、請求項２に記載の電撃式鳥害防止装置において、前記装置本体は、その長さ方向に直交する断面の形状が上方を開口させた略コ字状の樹脂成型品であって、底壁部にて下端間を連結された両側壁部の各上端から前記突片部が突設されており、鳥の飛来箇所に設けられた構造材に対して当該構造材の長さ方向に沿うように取り付けられることを特徴とする。
【００１０】
また、同じく電撃式鳥害防止装置に係る請求項４に記載の発明は、鳥の飛来箇所に設けられた構造材に取り付けられる所定長さの装置本体を有し、当該装置本体には飛来した鳥が留まった際に当該鳥に対して電気的ショックを与える電極部が装置本体の長さ方向に沿って延びるように設けられた電撃式鳥害防止装置において、前記装置本体は板状に形成され、その幅方向における中央部分の所定幅領域が装置本体の長さ方向へ延びる表面に撥水性を備えた絶縁領域とされる一方、その絶縁領域を幅方向両側から挟むようにして装置本体の長さ方向へ延びる各側部領域の表面上に前記電極部を構成する導電部が露出するように設けられていることを特徴とする。
【００１１】
また、請求項５に記載の発明は、請求項１〜請求項４のうち何れか一項に記載の電撃式鳥害防止装置において、前記電極部は、極性が異なる二つの導電部を含み給電手段から常時電圧を印加する構成とされ、当該二つの導電部に対して鳥が同時に接触した際には、前記印加電圧に基づいた電流が当該鳥の体内を通って一方の導電部から他方の導電部へ導通するように構成されていることを特徴とする。
【００１２】
【発明の実施の形態】
（第１の実施形態）
以下、本発明に係る電撃式鳥害防止装置（以下、「鳥害防止装置」ともいう。）の第１の実施形態を図１〜図３に従って説明する。
【００１３】
図１に示すように、本実施形態の鳥害防止装置１１は所定長さの装置本体１２を有しており、当該装置本体１２が送電線鉄塔上におけるカラスやハト等の鳥Ｂの飛来箇所に水平方向へ架設されたＬ型アングル材（構造材）１３に対して当該Ｌ型アングル材１３の長さ方向に沿うように取り付けられている。前記Ｌ型アングル材１３は、図２に二点鎖線で示すように、水平部１３ａと垂直部１３ｂとを備え、その長さ方向に直交する断面の形状がＬ字形状をなす周知の構造材であり、このようなＬ型アングル材１３が縦横・斜めに多数本組み合わされて送電線鉄塔は立設されている。
【００１４】
一方、前記装置本体１２は、図２に示すように、その長さ方向に直交する断面の形状が上方を開口させた略コ字状の絶縁性樹脂からなる長尺の樹脂成型品であり、底壁部１２ａに下端間を連結された両側壁部１２ｂ，１２ｃの各上端からは水平方向へ一対の突片部１２ｄ，１２ｅが対向するように突設されている。前記両突片部１２ｄ，１２ｅは、飛来した鳥Ｂの留まり部として機能するものであって、両突片部１２ｄ，１２ｅの先端同士の間には装置本体１２の長さ方向全体に亘り前記Ｌ型アングル材１３の平面視幅寸法よりも狭い幅寸法の空隙（間隙）Ｓが形成されている。
【００１５】
また、前記装置本体１２における各突片部１２ｄ，１２ｅの上面には、導電性樹脂からなる導電体（導電部）１４ａ，１４ｂが装置本体１２の長さ方向へ平行をなすように露出して設けられ、これら両導電体１４ａ，１４ｂにより一定条件下で鳥Ｂに電気的ショックを与えるための電極部１４が構成されている。前記両導電体１４ａ，１４ｂのうち、一方の導電体１４ａはプラス電極部とされ、他方の導電体１４ｂはマイナス電極部とされている。そして、これら両導電体１４ａ，１４ｂに対して前記底壁部１２ａの外底面に取着された給電手段１５が図示しない電気配線を介して接続され、当該給電手段１５からは常時電圧が印加されている。なお、本実施形態では、前記給電手段１５が図示しない太陽電池と変圧器とを組み合わせた構成とされている。
【００１６】
また、図１，２に示すように、前記装置本体１２の各側壁部１２ｂ，１２ｃにおいて装置本体１２の長さ方向へ所定間隔をおくように離間した複数位置（本実施形態では２位置）には両側壁部１２ｂ，１２ｃ間で互いに位置対応するように前後一対の係止孔（係止部）１６が貫通形成されている。そして、各係止孔１６には可撓性を有する樹脂製の結束部材１７が位置決め係止状態でそれぞれ挿通され、それらの結束部材１７により装置本体１２はＬ型アングル材１３に対し結束固定される構成となっている。なお、本実施形態では、前記結束部材１７が帯状をなすテープ体の一端に当該テープ体の他端側を巻き入れて締付けるロック機構１７ａ（図３参照）を備えた構成とされている。
【００１７】
以上のように構成された本実施形態の鳥害防止装置１１は、次のようにして送電線鉄塔上のＬ型アングル材１３に取り付けられる。まず、鳥害防止装置１１の装置本体１２をＬ型アングル材１３に対し両者の長さ方向が同一方向となるように配置する。そして、装置本体１２における両側壁部１２ｂ，１２ｃの上端側を少し外側へ弾性変形させながら、両突片部１２ｄ，１２ｅ間の空隙Ｓを拡げるようにし、その拡がった空隙Ｓを介してＬ型アングル材１３が装置本体１２の内側に組み入れられるようにする。
【００１８】
すると、前記装置本体１２は、Ｌ型アングル材１３に対して両突片部１２ｄ，１２ｅが掛止係合した仮止め状態となるので、その状態において装置本体１２がＬ型アングル材１３の長さ方向において所望する位置状態となるように位置関係を調節する。その後、装置本体１２の各係止孔１６に結束部材１７を挿通し、その挿通した結束部材１７により装置本体１２をＬ型アングル材１３に対して結束固定する。すると、鳥害防止装置１１は、図１及び図３に示すように、装置本体１２の突片部１２ｄ，１２ｅが留まり部として機能する予め設定した上方位置状態となる取付態様でＬ型アングル材１３に取り付けられる。なお、その取付態様において、装置本体１２の各突片部１２ｄ，１２ｅとＬ型アングル材１３との間には高さ方向へ隙間が形成される。
【００１９】
次に、上記のように構成された本実施形態の鳥害防止装置１１の作用について説明する。
さて、野外に立設された送電線鉄塔上には多数の鳥Ｂが営巣目的等で飛来し、水平方向に架設されて留まり木状をなすＬ型アングル材１３に留まろうとする。しかし、そのようなＬ型アングル材１３に対して上記の作業手順により鳥害防止装置１１の装置本体１２を取り付けておくと、図１に示すように、鳥Ｂは装置本体１２における両突片部１２ｄ，１２ｅ上に留まることになる。そして、両突片部１２ｄ，１２ｅ上に鳥Ｂが留まると、各突片部１２ｄ，１２ｅ上には電極部１４を構成する各導電体１４ａ，１４ｂが露出するように設けられているため、図３に示すように、その鳥Ｂの足Ｆは前記両導電体１４ａ，１４ｂに接触することになる。
【００２０】
すると、給電手段１５からの常時印加電圧に基づいた電流（例えば、０．４Ａ程度の低電流）がプラス電極部とされた一方の導電体１４ａからマイナス電極部とされた他方の導電体１４ｂへ鳥Ｂの体内を通って流れるため、当該鳥Ｂに電気的ショックを与えることができる。従って、その電気的ショックにより忌避反応を起こした鳥Ｂは前記突片部１２ｄ，１２ｅ上から飛び去り、また、その際の学習効果で二度と鳥害防止装置１１が取り付けられたＬ型アングル材１３には近付かないようになるため、鳥Ｂによる送電線鉄塔上への営巣行為が効果的に防止される。
【００２１】
ところで、前記Ｌ型アングル材１３に取り付けられた鳥害防止装置１１は野外立設された送電線鉄塔上に位置しているので、雨天時には装置本体１２上を雨水が流れることがある。また、寒冷時には電極部１４上等に結露が生じることもある。そのため、前記雨水や結露により電極部１４を構成する両導電体１４ａ，１４ｂ間が導通してしまうと、給電手段１５の電力を無駄に消費することになる。また、ときには前記両導電体１４ａ，１４ｂ間の導通により、不測の短絡事故を招いてしまう虞もある。しかし、本実施形態の場合は、以下の理由により、そのような電力の浪費及び短絡事故の虞を回避できる。
【００２２】
即ち、雨天時には鳥害防止装置１１における装置本体１２の各突片部１２ｄ，１２ｅ上を雨水が流れることになる。そのため、電極部１４を構成する各導電体１４ａ，１４ｂも濡れることになるが、両導電体１４ａ，１４ｂが設けられた各突片部１２ｄ，１２ｅ間には空隙Ｓが形成されているので、各突片部１２ｄ，１２ｅ上を流れる雨水は前記空隙Ｓから下方へ流れ落ちることになる。従って、両導電体１４ａ，１４ｂ間が前記雨水により導通することもない。また、寒冷時に前記導電体１４ａ，１４ｂ上に結露が生じた場合でも、両導電体１４ａ，１４ｂが設けられた各突片部１２ｄ，１２ｅ間には空隙Ｓが形成されているので、その結露によって両導電体１４ａ，１４ｂ間が導通することはない。
【００２３】
更に、給電手段１５から電極部１４を構成する両導電体１４ａ，１４ｂに対して常時電圧を印加する構成であっても、両導電体１４ａ，１４ｂの間には空隙Ｓが存在するため、たとえ突片部１２ｄ，１２ｅ上が表面汚損した場合でも、汚損漏洩電流が発生して両導電体１４ａ，１４ｂ間で導通するような事態が回避される。そして、鳥Ｂが前記両導電体１４ａ，１４ｂに同時に接触した際には、特別なスイッチ構成等を持っていなくても、前述した常時印加電圧に基づいた電流が鳥Ｂの体内を通って瞬時に導通することになる。
【００２４】
従って、上記した第１の実施形態の電撃式鳥害防止装置１１によれば、以下のような効果を得ることができる。
（１）上記実施形態では、鳥害防止装置１１の装置本体１２が雨風に晒される環境に設けられているが、雨天時には各突片部１２ｄ，１２ｅ上を流れる雨水が両突片部１２ｄ，１２ｅ間の空隙Ｓから下方へ流れ落ちるため、装置本体１２上の電極部１４の両導電体１４ａ，１４ｂ間が導通する事態を防止できる。また、寒冷時において各導電体１４ａ，１４ｂに結露が生じた場合でも、前記空隙Ｓの存在により両導電体１４ａ，１４ｂ間が結露により導通する事態を防止できる。従って、雨水や結露により両導電体１４ａ，１４ｂ間が導通して、給電手段１５の電力を浪費したり、不測の短絡事故を起こしたりする虞を確実に回避することができる。
【００２５】
（２）上記実施形態では、Ｌ型アングル材（構造材）１３に鳥害防止装置１１を取り付ける際、装置本体１２の両突片部１２ｄ，１２ｅ間の空隙ＳからＬ型アングル材１３を装置本体１２内に組み入れれば、結束部材１７により結束固定する前段階で、装置本体１２をＬ型アングル材１３に仮止めできる。従って、送電線鉄塔上において、取付作業が完了するまで装置本体１２を手で持ち続ける必要がなくなり、鳥害防止装置１１の取り付けに関わる作業負担を軽減できる。
【００２６】
（３）上記実施形態では、装置本体１２を結束部材１７によりＬ型アングル材１３に結束固定するようにした。従って、送電線鉄塔上での鳥害防止装置１１の取付作業を迅速且つ容易に行うことができる。しかも、前記結束部材１７は装置本体１２の各側壁部１２ｂ，１２ｃに形成された係止孔１６に位置決め係止するように挿通され、結束後においては装置本体１２の長さ方向へ位置ズレすることもない。従って、各係止孔１６の数に対応した複数の結束部材１７により装置本体１２を安定した結束固定状態で長期間に亘り確実に取り付けできる。
【００２７】
（４）上記実施形態では、装置本体１２における底壁部１２ａの外底面に給電手段１５が装置本体１２と一体化するように取着されている。そのため、前記装置本体１２をＬ型アングル材１３に対して結束部材１７により結束固定すれば、その鳥害防止装置１１における給電手段１５の取り付け作業をも同時に完了できるので、鳥害防止装置１１の取り付けに関わる作業時間を短縮できる。
【００２８】
（５）上記実施形態では、電極部１４を構成する両導電体１４ａ，１４ｂに給電手段１５から常時電圧を印加する構成とした場合でも、両導電体１４ａ，１４ｂ間が突片部１２ｄ，１２ｅの表面汚損等により導通することを空隙Ｓの存在によって回避できる。従って、野外に設置される電撃式鳥害防止装置１１としては、長期に亘って機能を良好に維持することができ、実用的効果を発揮することができる。
【００２９】
（６）また、上記実施形態では、両導電体１４ａ，１４ｂに鳥Ｂが同時に接触した際には、給電手段１５からの常時印加電圧に基づいた電流が特別なスイッチ構成によるオン作動に依存することなく瞬時に鳥Ｂの体内に導通するため、電撃式鳥害防止装置１１の装置コスト低減にも貢献できる。
【００３０】
（７）また、上記実施形態では、飛来した鳥Ｂが接触した際に電気的ショックを与えるための電極部１４を、装置本体１２の上部側で装置本体１２の長さ方向（所定方向）へ延びる一対（複数）の導電体（導電部）１４ａ，１４ｂからなる構成とした。そのため、構造が簡単で、設置場所に応じて長さを自由に調整することが可能であり、飛来した鳥Ｂが装置本体１２上の長さ方向におけるどの位置に留まっても、当該鳥Ｂに確実に電気的ショックを与えることができる。
【００３１】
（第２の実施形態）
次に、本発明の第２の実施形態を図４に従って説明する。
図４に示すように、本実施形態の鳥害防止装置２１は、板状に形成された所定長さの装置本体２２を有しており、当該装置本体２２が電柱（図示略）上において水平方向へ支持された腕金（構造材）２３に対して当該腕金２３の長さ方向に沿うように取り付けられている。前記腕金２３は、四角筒状をなす周知の構造材であり、通常は、電線の支持碍子を固定した上面が水平状態となる態様で支持されるため、留まり木状をなす腕金２３の上面にはカラスやハト等の鳥Ｂが飛来して留まることが多い。
【００３２】
一方、前記装置本体２２は、フッ素系樹脂にて所定幅（例えば、３５ｍｍ幅）の板体に形成された絶縁体２４と、導電性樹脂にて所定幅（例えば、５ｍｍ幅）の板体に形成された一対の導電体２５ａ，２５ｂとが互いに接合されて板状体に一体化された構成になっている。即ち、図４に示すように、前記絶縁体２４と両導電体２５ａ，２５ｂとは、両導電体２５ａ，２５ｂが絶縁体２４を幅方向両側から挟む位置関係で且つそれぞれの上面が面一になる態様で、互いに対応する側端面同士を接合されている。そして、前記装置本体２２では、絶縁体２４の表面領域（所定幅領域）が撥水性を備えた絶縁部（絶縁領域）Ｓ１とされる一方、前記両導電体２５ａ，２５ｂの各表面領域（側部領域）が導電部とされ、一定条件下において鳥Ｂに電気的ショックを与えるための電極部２５が構成されている。
【００３３】
なお、前記電極部２５は、前記第１の実施形態の場合と同様に、両導電体２５ａ，２５ｂのうち、一方の導電体２５ａがプラス電極部とされ、他方の導電体２５ｂがマイナス電極部とされている。そして、図示はしないが、これら両導電体２５ａ，２５ｂに対して、前記第１の実施形態の給電手段１５と同様の給電手段（本実施形態の場合は、腕金２３上に装置本体２２とは別に取り付けられているものとする。）が電気配線を介して接続され、当該給電手段１５からは常時電圧が印加されている。
【００３４】
また、図４に示すように、前記装置本体２２の下面には、当該装置本体２２と平面視形状が略同一のシート体２６が、当該シート体２６と装置本体２２との間に可撓性を有する一対の樹脂製の結束部材２７を上下両側から挟み込む態様で、樹脂溶接されている。前記結束部材２７は、装置本体２２の長さ方向へ所定間隔をおくように離間した複数位置（本実施形態では２位置）において装置本体２２の長さ方向と直交する方向（幅方向）に沿って延びるように位置決め状態で挟持固定されている。なお、本実施形態の結束部材２７も、前記第１の実施形態の結束部材１７と同様に、帯状をなすテープ体の一端に当該テープ体の他端側を巻き入れて締付けるロック機構（図示略）を備えた構成とされている。
【００３５】
以上のように構成された本実施形態の鳥害防止装置２１は、次のようにして電柱上の腕金２３に取り付けられる。まず、腕金２３の上面に鳥害防止装置２１の装置本体２２をシート体２６が接するように載置した後、その装置本体２２及び腕金２３の両者の長さ方向が同一方向となるように位置合せする。そして、その状態において、腕金２３上の装置本体２２から両側下方へ垂れ下がっている前記各結束部材２７により装置本体２２を腕金２３に対して結束固定する。すると、鳥害防止装置２１は、図４に示すように、装置本体２２の表面（上面）側が留まり部として機能する予め設定した上方位置状態となる取付態様で腕金２３に取り付けられる。
【００３６】
次に、上記のように構成された本実施形態の電撃式鳥害防止装置２１の作用について説明する。
さて、市街地の道路脇等に立設された電柱上には多数の鳥Ｂが飛来し、水平方向に支持されて留まり木状をなす腕金２３に留まろうとする。しかし、そのような腕金２３に対して上記の作業手順により鳥害防止装置２１の装置本体２２を取り付けておくと、その鳥Ｂは装置本体２２上に留まることになる。そして、その装置本体２２上に鳥Ｂが留まると、装置本体２２の表面上には電極部２５を構成する各導電体２５ａ，２５ｂの表面（上面）が露出しているため、その鳥Ｂの足は前記両導電体２５ａ，２５ｂに接触することになる。
【００３７】
すると、前記給電手段からの常時印加電圧に基づいた電流（例えば、０．４Ａ程度の低電流）が一方の導電体２５ａから他方の導電体２５ｂへ鳥Ｂの体内を通って流れるため、当該鳥Ｂに電気的ショックを与えることができる。従って、その電気的ショックにより忌避反応を起こした鳥Ｂは前記装置本体２２上から飛び去り、また、その際の学習効果で二度と鳥害防止装置２１が取り付けられた腕金２３には近付かないようになるため、以後において電柱上へ鳥Ｂが飛来して留まることが防止される。
【００３８】
また、本実施形態の鳥害防止装置２１が取り付けられる構造材である腕金２３も、野外に立設された電柱上に支持されるものであるため、雨天時には、その鳥害防止装置２１の装置本体２２上を雨水が流れることになる。また、寒冷時には電極部２５上等に結露が生じることもある。そのため、前記雨水や結露により電極部２５を構成する両導電体２５ａ，２５ｂ間が導通してしまうと、給電手段の電力の浪費及び不測の短絡事故を招くという虞がある。しかし、本実施形態の場合、以下の理由により、そのような電力の浪費及び短絡事故の虞を回避できる。
【００３９】
即ち、雨天時には鳥害防止装置２１における装置本体２２の表面も雨水により濡れてしまい、ときには絶縁体２４の表面領域（絶縁部Ｓ１）を横断して電極部２５の両導電体２５ａ，２５ｂ間を連絡するように雨水が流れようとする。しかし、本実施形態では、両導電体２５ａ，２５ｂ間に位置する絶縁体２４が撥水性を有するフッ素系樹脂により形成されているため、その表面領域（絶縁部Ｓ１）では、図４に一点鎖線で示すように、雨水の流れが複数の水滴粒（Ｗ）に分離されることになる。
【００４０】
そのため、雨天時において装置本体２２の表面が雨水により濡れたとしても、その装置本体２２上に露出した電極部２５の両導電体２５ａ，２５ｂ間が雨水の流れで連絡して導通することはない。また、寒冷時において電極部２５の両導電体２５ａ，２５ｂ上に結露が生じたとしても、両導電体２５ａ，２５ｂ間に位置する所定幅の絶縁体２４は表面領域（絶縁部Ｓ１）が撥水性を有しているため、同様に、両導電体２５ａ，２５ｂ間が雨水の流れで導通することはない。
【００４１】
更に、給電手段１５から電極部２５を構成する両導電体２５ａ，２５ｂに対して常時電圧を印加する構成であるため、鳥Ｂが前記両導電体１４ａ，１４ｂに同時に接触した際には、特別なスイッチ構成等を持っていなくても、前述した常時印加電圧に基づいた電流が鳥Ｂの体内を通って瞬時に導通することになる。
【００４２】
従って、上記した第２の実施形態の電撃式鳥害防止装置２１によれば、第１の実施形態における前記（１）に記載の効果と同様に、雨水や結露によって電極部２５の両導電体２５ａ，２５ｂ間が導通することを防止でき、無駄な電力の浪費や短絡事故の虞を回避できる。また、第１の実施形態における前記（３）に記載の効果と同様に、装置本体２２を結束部材２７により腕金２３に結束固定するようにしたので、電柱上での鳥害防止装置２１の取付作業を迅速且つ容易に行うことができる。また、第１の実施形態における前記（６）に記載の効果と同様に、鳥Ｂに対し電気的ショックを与えるために特別なスイッチ構成等を必要としないので、電撃式鳥害防止装置２１の装置コスト低減にも貢献できる。更には、第１の実施形態における前記（７）に記載の効果と同様に、飛来した鳥Ｂが装置本体１２上の長さ方向におけるどの位置に留まっても、当該鳥Ｂに確実に電気的ショックを与えることができる。
【００４３】
そして更に、この第２の実施形態においては、次のような特有の効果がある。
（８）即ち、上記実施形態（第２の実施形態）では、装置本体１２の断面形状が上方を開口させた略コ字状をなしていた第１実施形態の場合と異なり、装置本体２２が板状体であるため、取付箇所となる構造材が腕金２３のように断面矩形状をなすものである場合も、その上面に載置して取り付けることができる。また、取付箇所となる構造材が断面円形状又は不定形状をなすもの（例えば、樹木の枝など）である場合にも、その上面に装置本体２２を載置できる限り、本実施形態の鳥害防止装置２１を取り付けることができる。
【００４４】

[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
(1st Embodiment)
Hereinafter, a first embodiment of an electric shock type bird harm prevention device (hereinafter, also referred to as a “bird harm prevention device”) according to the present invention will be described with reference to FIGS.
[0013]
As shown in FIG. 1, the bird harm prevention device 11 of the present embodiment has a device main body 12 of a predetermined length, and the device main body 12 is a place where birds B such as crows and pigeons fly on a power transmission tower. Is attached to an L-shaped angle member (structural material) 13 extending in the horizontal direction along the length direction of the L-shaped angle member 13. As shown by a two-dot chain line in FIG. 2, the L-shaped angle member 13 includes a horizontal portion 13a and a vertical portion 13b, and is a well-known structural material having a L-shaped cross section orthogonal to its length direction. A number of such L-shaped angle members 13 are vertically and horizontally and diagonally combined to form a transmission line tower.
[0014]
On the other hand, as shown in FIG. 2, the device main body 12 is a long resin molded product made of a substantially U-shaped insulating resin having a cross section orthogonal to the length direction and having an upper opening. A pair of protruding pieces 12d, 12e project in the horizontal direction from upper ends of both side walls 12b, 12c having a lower end connected to the bottom wall 12a. The two projecting pieces 12d and 12e function as a staying part for the bird B that has come flying, and the distance between the tips of the two projecting pieces 12d and 12e extends over the entire length of the apparatus body 12. A gap (gap) S having a width smaller than the width in plan view of the L-shaped angle member 13 is formed.
[0015]
On the upper surfaces of the projecting pieces 12d and 12e of the device main body 12, conductors (conductive portions) 14a and 14b made of a conductive resin are exposed so as to be parallel to the longitudinal direction of the device main body 12. The two conductors 14a and 14b constitute an electrode section 14 for applying an electric shock to the bird B under certain conditions. Of the two conductors 14a and 14b, one conductor 14a is a plus electrode portion, and the other conductor 14b is a minus electrode portion. Then, a power supply means 15 attached to the outer bottom surface of the bottom wall 12a is connected to both of the conductors 14a and 14b via an electric wiring (not shown), and a voltage is constantly applied from the power supply means 15. ing. In the present embodiment, the power supply means 15 is configured by combining a solar cell (not shown) and a transformer.
[0016]
Further, as shown in FIGS. 1 and 2, each of the side walls 12 b and 12 c of the apparatus main body 12 is located at a plurality of positions (two positions in the present embodiment) which are separated by a predetermined distance in the length direction of the apparatus main body 12. A pair of front and rear locking holes (locking portions) 16 are formed to penetrate so as to correspond to each other between the side wall portions 12b and 12c. A flexible resin bundling member 17 is inserted into each locking hole 16 in a positioning and locked state, and the apparatus body 12 is bound and fixed to the L-shaped angle member 13 by the bundling members 17. Configuration. In the present embodiment, the binding member 17 is provided with a lock mechanism 17a (see FIG. 3) that winds and tightens the other end of the tape body at one end of the band-shaped tape body.
[0017]
The bird harm prevention device 11 of the present embodiment configured as described above is attached to the L-shaped angle member 13 on the power transmission tower as follows. First, the device main body 12 of the bird harm prevention device 11 is arranged with respect to the L-shaped angle member 13 such that the length directions thereof are the same. The space S between the two protruding pieces 12d and 12e is expanded while slightly elastically deforming the upper ends of the side walls 12b and 12c of the apparatus body 12 outward, and the L-shape is formed through the expanded space S. The angle member 13 is incorporated inside the apparatus main body 12.
[0018]
Then, the device main body 12 is in a temporary fixing state in which the two protruding pieces 12 d and 12 e are engaged with the L-shaped angle member 13. The positional relationship is adjusted so as to obtain a desired position in the vertical direction. Thereafter, the binding member 17 is inserted into each locking hole 16 of the apparatus main body 12, and the apparatus main body 12 is bound and fixed to the L-shaped angle member 13 by the inserted binding member 17. Then, as shown in FIGS. 1 and 3, the bird harm prevention device 11 has an L-shaped angle material in a mounting mode in which the projecting pieces 12 d and 12 e of the device main body 12 are in a predetermined upper position functioning as a retaining portion. 13 is attached. In the mounting mode, a gap is formed in the height direction between each of the projecting pieces 12 d and 12 e of the apparatus main body 12 and the L-shaped angle member 13.
[0019]
Next, the operation of the bird harm prevention device 11 of the present embodiment configured as described above will be described.
Now, a large number of birds B fly for nesting purposes and the like on the transmission line tower erected in the field and try to stay on the L-shaped angle member 13 which is erected in a horizontal direction and forms a perch. However, if the device main body 12 of the bird harm prevention device 11 is attached to such an L-shaped angle member 13 according to the above-described operation procedure, as shown in FIG. It will stay on the parts 12d and 12e. Then, when the bird B stays on the both protruding pieces 12d and 12e, the conductors 14a and 14b constituting the electrode section 14 are provided on the protruding pieces 12d and 12e so as to be exposed. As shown in FIG. 3, the foot F of the bird B comes into contact with the conductors 14a and 14b.
[0020]
Then, a current (for example, a low current of about 0.4 A) based on the constantly applied voltage from the power supply means 15 is transferred from one conductor 14a serving as a plus electrode to the other conductor 14b serving as a minus electrode. Since the bird B flows through the body of the bird B, an electrical shock can be given to the bird B. Therefore, the bird B which has caused the repelling reaction by the electric shock flies off from the protruding pieces 12d and 12e, and the L-type angle member 13 to which the bird harm prevention device 11 is attached again by the learning effect at that time. The birds B are effectively prevented from nesting on the power transmission tower.
[0021]
By the way, since the bird harm prevention device 11 attached to the L-shaped angle member 13 is located on a power transmission tower installed outdoors, rainwater may flow on the device body 12 in rainy weather. In cold weather, dew may be formed on the electrode section 14 or the like. Therefore, if the conductors 14a and 14b constituting the electrode portion 14 are electrically connected to each other due to the rainwater or dew, the power of the power supply means 15 is wasted. Further, sometimes, there is a possibility that an unexpected short circuit accident may be caused by conduction between the conductors 14a and 14b. However, in the case of the present embodiment, it is possible to avoid such a waste of power and a risk of a short circuit accident for the following reasons.
[0022]
That is, during rainy weather, rainwater flows on the projecting pieces 12d and 12e of the device main body 12 in the bird harm prevention device 11. Therefore, the conductors 14a and 14b constituting the electrode portion 14 also become wet, but since the gap S is formed between the protruding pieces 12d and 12e provided with the conductors 14a and 14b, The rainwater flowing on each of the projecting pieces 12d and 12e flows downward from the gap S. Therefore, there is no conduction between the conductors 14a and 14b due to the rainwater. Further, even when dew condensation occurs on the conductors 14a and 14b during cold weather, the space S is formed between the protruding pieces 12d and 12e provided with the conductors 14a and 14b. As a result, conduction between the conductors 14a and 14b does not occur.
[0023]
Further, even when the voltage is always applied from the power supply means 15 to the conductors 14a and 14b constituting the electrode section 14, the gap S exists between the conductors 14a and 14b. Even when the surface of the protruding pieces 12d and 12e is contaminated, a situation in which a contaminated leakage current is generated and the conduction between the conductors 14a and 14b is avoided. When the bird B comes into contact with the conductors 14a and 14b at the same time, the current based on the constantly applied voltage instantaneously passes through the body of the bird B, even if the bird B does not have a special switch configuration or the like. Will be conducted.
[0024]
Therefore, according to the electric shock type bird harm prevention device 11 of the first embodiment, the following effects can be obtained.
(1) In the above-described embodiment, the device body 12 of the bird harm prevention device 11 is provided in an environment where it is exposed to rain and wind, but when it rains, rainwater flowing on each of the projecting portions 12d and 12e causes the two projecting portions 12d, Since the water flows downward from the gap S between the electrodes 12e, it is possible to prevent a situation in which the conductors 14a and 14b of the electrode portion 14 on the apparatus main body 12 are electrically connected. Further, even when dew condensation occurs on each of the conductors 14a and 14b during cold weather, it is possible to prevent a situation in which the conductors 14a and 14b become conductive due to dew condensation due to the presence of the gap S. Therefore, it is possible to reliably avoid the possibility that the conductors 14a and 14b are electrically connected to each other due to rainwater or dew, and thus waste the power of the power supply means 15 or cause an unexpected short circuit accident.
[0025]
(2) In the above embodiment, when the bird harm prevention device 11 is attached to the L-shaped angle member (structural material) 13, the L-shaped angle member 13 is removed from the gap S between the two projecting pieces 12 d and 12 e of the device main body 12. If incorporated in the main body 12, the apparatus main body 12 can be temporarily fixed to the L-shaped angle material 13 before being fixed and bound by the binding member 17. Therefore, it is not necessary to hold the apparatus main body 12 by hand on the transmission line tower until the installation operation is completed, and the work load related to the installation of the bird harm prevention device 11 can be reduced.
[0026]
(3) In the above embodiment, the apparatus main body 12 is bound and fixed to the L-shaped angle member 13 by the binding member 17. Therefore, the work of mounting the bird harm prevention device 11 on the power transmission tower can be performed quickly and easily. Moreover, the binding member 17 is inserted so as to be positioned and locked in the locking holes 16 formed in the side walls 12b and 12c of the apparatus main body 12, and is displaced in the length direction of the apparatus main body 12 after the binding. Not even. Therefore, the apparatus main body 12 can be securely attached for a long period of time in a stable binding and fixed state by the plurality of binding members 17 corresponding to the number of the locking holes 16.
[0027]
(4) In the above embodiment, the power supply means 15 is attached to the outer bottom surface of the bottom wall portion 12 a of the device main body 12 so as to be integrated with the device main body 12. Therefore, if the device main body 12 is bound and fixed to the L-shaped angle member 13 by the binding member 17, the work of attaching the power supply means 15 in the bird harm prevention device 11 can be completed at the same time, so that the bird harm prevention device 11 Work time related to installation can be reduced.
[0028]
(5) In the above embodiment, even when the voltage is always applied from the power supply means 15 to the conductors 14a and 14b constituting the electrode section 14, the protruding pieces 12d and 12e are formed between the conductors 14a and 14b. Can be avoided by the presence of the gap S. Therefore, the function of the electric shock type bird harm prevention device 11 installed outdoors can be maintained satisfactorily over a long period of time, and a practical effect can be exhibited.
[0029]
(6) In the above-described embodiment, when the bird B simultaneously contacts the conductors 14a and 14b, the current based on the constantly applied voltage from the power supply means 15 depends on the ON operation by a special switch configuration. Since it is instantaneously conducted into the body of the bird B without being involved, it is possible to contribute to a reduction in the cost of the electric shock type bird harm prevention device 11.
[0030]
(7) In the above embodiment, the electrode portion 14 for applying an electric shock when the flying bird B comes into contact with the bird B is arranged in the length direction (predetermined direction) of the device main body 12 on the upper side of the device main body 12. It is configured to include a pair (plurality) of conductors (conductive portions) 14a and 14b extending. Therefore, the structure is simple, the length can be freely adjusted according to the installation location, and even if the flying bird B stays at any position in the length direction on the apparatus main body 12, the bird B An electric shock can be reliably applied.
[0031]

As shown in FIG. 4, the bird harm prevention device 21 of the present embodiment has a device main body 22 having a predetermined length formed in a plate shape, and the device main body 22 is horizontally mounted on a utility pole (not shown). The arm member (structural material) 23 supported in the direction is attached along the length direction of the arm member 23. The arm bar 23 is a well-known structural member having a square tubular shape. Usually, the arm bar 23 is supported in such a manner that the upper surface to which the support insulator of the electric wire is fixed is in a horizontal state. Birds B such as crows and pigeons often fly and stay on the upper surface.
[0032]
On the other hand, the device main body 22 includes an insulator 24 formed of a fluororesin on a plate having a predetermined width (for example, 35 mm width) and a conductive resin formed on a plate having a predetermined width (for example, 5 mm width). The formed pair of conductors 25a and 25b are joined to each other and integrated into a plate. That is, as shown in FIG. 4, the insulator 24 and the conductors 25a and 25b are in a positional relationship in which the conductors 25a and 25b sandwich the insulator 24 from both sides in the width direction and the upper surfaces thereof are flush with each other. In this manner, the corresponding side end surfaces are joined to each other. In the device body 22, the surface region (predetermined width region) of the insulator 24 is an insulating portion (insulating region) S1 having water repellency, while the surface region (side) of the conductors 25a and 25b is formed. The part area is a conductive part, and an electrode part 25 for applying an electric shock to the bird B under certain conditions is configured.
[0033]
In addition, as in the case of the first embodiment, one of the conductors 25a and 25b has a positive electrode portion, and the other conductor 25b has a negative electrode portion. It has been. Although not shown, a power supply unit similar to the power supply unit 15 of the first embodiment (in the case of the present embodiment, the device main body 22 Are connected separately via electric wiring, and a voltage is constantly applied from the power supply means 15.
[0034]
As shown in FIG. 4, on the lower surface of the device main body 22, a sheet body 26 having substantially the same planar shape as the device main body 22 is provided between the sheet body 26 and the device main body 22. Are resin-welded in such a manner as to sandwich a pair of resin binding members 27 having upper and lower sides from both upper and lower sides. The bundling member 27 extends in a direction (width direction) orthogonal to the length direction of the device main body 22 at a plurality of positions (two positions in the present embodiment) separated at a predetermined interval in the length direction of the device main body 22. It is pinched and fixed in a positioning state so as to extend. Note that, similarly to the binding member 17 of the first embodiment, the binding member 27 of the present embodiment also includes a lock mechanism (not shown in the drawing) that winds the other end of the tape body around one end of the belt-shaped tape body. ).
[0035]
The bird harm prevention device 21 of the present embodiment configured as described above is attached to the arm 23 on a utility pole as follows. First, after the apparatus main body 22 of the bird harm prevention device 21 is placed on the upper surface of the arm 23 so that the sheet body 26 is in contact therewith, the length direction of both the apparatus main body 22 and the arm 23 is in the same direction. Align to. Then, in this state, the apparatus main body 22 is bound and fixed to the arm 23 by the respective binding members 27 hanging down from both sides of the apparatus main body 22 on the arm 23. Then, as shown in FIG. 4, the bird harm prevention device 21 is attached to the arm 23 in such a manner that the front surface (upper surface) side of the device main body 22 is in a predetermined upper position functioning as a retaining portion.
[0036]
Next, the operation of the electric shock type bird harm prevention device 21 of the present embodiment configured as described above will be described.
Now, a large number of birds B fly on a telephone pole erected on the side of a road in an urban area, and try to stay on the arm bar 23 which is supported in the horizontal direction and forms a perch. However, if the device main body 22 of the bird harm prevention device 21 is attached to such an arm 23 according to the above-mentioned operation procedure, the bird B will remain on the device main body 22. When the bird B stays on the device main body 22, the surface (upper surface) of each of the conductors 25 a and 25 b constituting the electrode unit 25 is exposed on the surface of the device main body 22. The foot comes into contact with the conductors 25a and 25b.
[0037]
Then, a current (for example, a low current of about 0.4 A) based on the constantly applied voltage from the power supply means flows from one conductor 25a to the other conductor 25b through the body of the bird B. B can be electrically shocked. Therefore, the bird B that has caused a repelling reaction due to the electric shock flies off the device main body 22 and does not approach the arm 23 to which the bird harm prevention device 21 is attached again due to the learning effect at that time. Therefore, the bird B is prevented from flying and staying on the telephone pole.
[0038]
In addition, since the arm 23 which is a structural material to which the bird harm prevention device 21 of the present embodiment is attached is also supported on a telephone pole erected outdoors, the rain damage prevention device 21 can be used in rainy weather. Rainwater flows on the apparatus main body 22. In cold weather, dew may be formed on the electrode section 25 or the like. Therefore, if the conductors 25a and 25b constituting the electrode portion 25 are electrically connected to each other due to the rainwater or the dew, there is a possibility that the power of the power supply means is wasted and an unexpected short circuit accident occurs. However, in the case of the present embodiment, it is possible to avoid such a waste of power and a risk of a short circuit accident for the following reasons.
[0039]
That is, during rainy weather, the surface of the device main body 22 of the bird harm prevention device 21 also gets wet with rainwater, and sometimes crosses the surface region of the insulator 24 (insulating portion S1) and passes between the conductors 25a and 25b of the electrode portion 25. Rainwater is going to flow as if to contact. However, in the present embodiment, since the insulator 24 located between the conductors 25a and 25b is formed of a water-repellent fluorine-based resin, its surface region (insulating portion S1) is indicated by a chain line in FIG. As shown by, the flow of rainwater is separated into a plurality of water droplets (W).
[0040]
Therefore, even if the surface of the device main body 22 is wet by rainwater in rainy weather, the two conductors 25a and 25b of the electrode portion 25 exposed on the device main body 22 do not communicate with each other by the flow of rainwater. . Also, even if dew condensation occurs on both conductors 25a and 25b of electrode portion 25 during cold weather, insulator 24 of a predetermined width located between both conductors 25a and 25b has a repelling surface area (insulating portion S1). Since it is water-based, similarly, there is no conduction between the conductors 25a and 25b due to the flow of rainwater.
[0041]
Further, since the voltage is always applied from the power supply means 15 to the conductors 25a and 25b constituting the electrode unit 25, when the bird B simultaneously contacts the conductors 14a and 14b, a special Even if it does not have a simple switch configuration or the like, the current based on the above-described constantly applied voltage is instantaneously conducted through the body of the bird B.
[0042]
Therefore, according to the electric shock type bird harm prevention device 21 of the above-described second embodiment, both the conductors of the electrode portion 25 are exposed to rainwater or dew condensation, similarly to the effect described in (1) in the first embodiment. It is possible to prevent continuity between 25a and 25b, and to avoid waste of power and short circuit accidents. Further, similar to the effect described in the above (3) in the first embodiment, the device main body 22 is bound and fixed to the arm 23 by the binding member 27, so that the bird harm prevention device 21 on the utility pole can be prevented. The mounting operation can be performed quickly and easily. Further, similar to the effect described in the above (6) in the first embodiment, since a special switch configuration or the like is not required for applying an electric shock to the bird B, the electric shock type bird harm prevention device 21 is not required. It can also contribute to reducing equipment costs. Further, similarly to the effect described in (7) in the first embodiment, even if the flying bird B stays at any position in the length direction on the apparatus main body 12, the bird B is reliably electrically connected to the bird B. Can shock.
[0043]
Further, the second embodiment has the following specific effects.
(8) That is, in the above-described embodiment (second embodiment), unlike the first embodiment in which the cross-sectional shape of the device main body 12 has a substantially U-shape with an open top, the device main body 22 is Since it is a plate-like body, even when the structural material serving as the mounting portion has a rectangular cross section like the arm bar 23, it can be mounted and mounted on the upper surface thereof. Further, even when the structural material serving as an attachment portion has a circular cross section or an irregular shape (for example, a tree branch or the like), as long as the apparatus main body 22 can be mounted on the upper surface thereof, the bird harm of the present embodiment is not affected. The prevention device 21 can be attached.
