Description
本発明は、畑の周囲に設置して猿、猪、ハクビシン、アナグマなど（以後これらを「害獣」と呼ぶ。）の侵入を防止するネット式電気柵に関するものである。The present invention relates to a net-type electric fence that is installed around a field to prevent intrusion of monkeys, rabbits, raccoons, badgers and the like (hereinafter referred to as “harmful animals”).
近年山間地域の畑において害獣の侵入による被害が多発しているため、畑の作物の周囲に電気柵を設置することが行なわれている。図１に示す従来のネット式電気柵は、以下のような構成で畑に侵入しようとする害獣を感電させて撃退するものである。このような従来のネット式電気柵に関する技術について述べた文献として、実願平４−７６８９３がある。
（１）畑の周囲の地表に、数ｍ間隔に絶縁物製の支柱１を立設する。
（２）絶縁物製の撚線で作られた網により電気柵ネット２の長さ方向に帯状に形成された絶縁帯２ｂと、繊維に金属線を撚り込んだ撚線で作られた網により電気柵ネット２の長さ方向に帯状に形成された導電帯２ａを、交互に配置した電気柵ネット２を支柱１に張設する。電気柵ネット２の最下部の網目に通してあるロープ２ｃを留め具４により地面に固定する。
（３）下から数えて奇数番目の導電帯２ａを、６，０００Ｖ〜７，０００Ｖの衝撃高圧を発生する衝撃高圧電源３のプラス側に接続し、下から数えて偶数番目の導電帯２ａと地中に打ち込んだ接地極５を、衝撃高圧電源３のマイナス側に接続する。In recent years, damage caused by the invasion of pests has frequently occurred in mountainous fields, and electric fences have been installed around field crops. The conventional net-type electric fence shown in FIG. 1 repels an electric shock of a harmful animal that is about to enter a field with the following configuration. Japanese Patent Application No. Hei 4-76893 is a document describing such a conventional network electric fence.
(1) Erecting columns 1 made of an insulating material are provided at intervals of several meters on the ground surface around the field.
(2) With an insulating band 2b formed in a band shape in the length direction of the electric fence net 2 by a net made of a twisted wire made of an insulator, and a net made of a twisted wire in which a metal wire is twisted into a fiber The electric fence net 2 in which the conductive bands 2 a formed in a band shape in the length direction of the electric fence net 2 are alternately arranged is stretched on the support column 1. A rope 2 c passed through the lowermost mesh of the electric fence net 2 is fixed to the ground with a fastener 4.
(3) The odd-numbered conductive bands 2a counted from the bottom are connected to the positive side of the shock high-voltage power supply 3 that generates a high-impact high voltage of 6,000V to 7,000V, and the even-numbered conductive bands 2a counted from the bottom The ground electrode 5 driven into the ground is connected to the negative side of the impact high voltage power source 3.
図１に示す従来のネット式電気柵には、以下のような問題があった。
（１）人体への安全上の配慮から、導電帯２ａに印加される衝撃高圧は連続印加ではなく、約１秒間の間隔で約０．１秒間だけ印加される。運動能力に優れた猿は素早く電気柵ネット２をよじ登るので、衝撃高圧電源３のプラス側に接続された導電帯２ａと、マイナス側に接続された導電帯２ａを同時に掴んでも、短時間の内に次の動作に移ってその状態は壊れてしまう。このように猿が短時間だけ感電する状況にあっても、そのタイミングが約１秒間隔で発生する約０．１秒間の通電時間に一致しなければ、猿は感電せずに電気柵ネット２をよじ登り乗り越えてしまう。
（２）撓み易い電気柵ネット２に比べて支柱１は掴み易いので、猿は短時間でよじ登れる。約１秒間の非通電時間のうちに猿がこの支柱１を掴んでよじ登り、感電せずに電気柵を乗り越えてしまう。
（３）猿は電気柵ネット２の最下部の絶縁帯２ｂの撚線を噛み切って、感電せずに侵入してしまう。また猿が最下部の網目に通してあるロープ２ｃを噛み切ると、ロープ２ｃに緩みができるので、猿はロープ２ｃを持ち上げて電気柵ネット２の下を潜り抜けてしまう。猿が噛み切った場所から、猪やハクビシンも侵入してしまう。
（４）電気柵ネット２の最下部にあるロープ２ｃは留め具４により地面に固定されるが、地面に凹凸がある、固定されたロープ２ｃが経年変化で緩む、ロープ２ｃを１ヶ所で持ち上げると付近の緩みがそこに集積するなどの理由により、地面とロープ２ｃの間に隙間ができるので、猫と同様に頭が入ればその隙間を通過できるハクビシンがそこから侵入してしまう。
（５）電気柵ネット２の最下部にあるロープ２ｃは留め具４により地面に固定されるが、アナグマは地面を掘って電気柵ネット２の下を潜り抜けてしまう。そしてアナグマが掘った穴からハクビシンや子供の猿も侵入してしまう。
（６）電気柵付近の地表に生えた草が成長して電気柵ネット２の導電帯２ａに接触すると、漏電により衝撃高圧が下がってしまうので、電気柵の性能を維持するためには電気柵ネット２付近の草刈りを頻繁に行わなければならない。
（７）猿が電気柵ネット２をよじ登る間に感電させるしくみなので、電気柵ネット２の高さは「猿がジャンプして手が届く最大の高さ（約２ｍ）」以上でなければならない。そのために支柱１の長さは、地中に打ち込む長さ約８０ｃｍを含めると３ｍ近くになるので、ハンマーを使って支柱１を立設するのが困難である。The conventional net type electric fence shown in FIG. 1 has the following problems.
(1) In consideration of safety to the human body, the impact high voltage applied to the conductive band 2a is not continuously applied, but is applied for about 0.1 second at intervals of about 1 second. Since monkeys with excellent athletic ability climb up the electric fence net 2 quickly, even if the conductive band 2a connected to the positive side of the impact high-voltage power supply 3 and the conductive band 2a connected to the negative side are grasped at the same time, In the next operation, the state is broken. Thus, even if the monkey is in a situation of electric shock for a short time, if the timing does not coincide with the energization time of about 0.1 seconds generated at intervals of about 1 second, the monkey does not get an electric shock and the electric fence net 2 I climbed up and got over.
(2) Compared with the electric fence net 2 which is easy to bend, the column 1 is easy to grasp, so that the monkey can climb in a short time. The monkey grabs the support column 1 and climbs up within about 1 second of de-energization time and gets over the electric fence without electric shock.
(3) The monkey bites through the stranded wire of the lowermost insulating band 2b of the electric fence net 2 and enters without electric shock. Further, when the monkey bites the rope 2c passing through the lowermost mesh, the rope 2c can be loosened, and the monkey lifts the rope 2c and goes under the electric fence net 2. Spiders and hakubishin also invade from where the monkey bites.
(4) The rope 2c at the bottom of the electric fence net 2 is fixed to the ground by the fastener 4, but the ground is uneven, the fixed rope 2c is loosened over time, the rope 2c is lifted at one place A gap is formed between the ground and the rope 2c because the looseness in the vicinity accumulates there, and if the head enters like a cat, a hakubicin that can pass through the gap will enter from there.
(5) Although the rope 2c at the bottom of the electric fence net 2 is fixed to the ground by the fastener 4, the badger digs into the ground and goes under the electric fence net 2. Hakubishin and children's monkeys also invade through the holes dug by badgers.
(6) When the grass growing on the surface near the electric fence grows up and contacts the conductive band 2a of the electric fence net 2, the impact high voltage is reduced due to electric leakage. To maintain the performance of the electric fence, use the electric fence. Mowing around the net 2 must be done frequently.
(7) Since the monkey climbs the electric fence net 2 to get an electric shock, the height of the electric fence net 2 must be equal to or greater than the “maximum height that the monkey can jump to reach (about 2 m)”. For this reason, the length of the support column 1 is close to 3 m when the length of about 80 cm to be driven into the ground is included. Therefore, it is difficult to erect the support column 1 using a hammer.
そこで本発明が解決しようとする課題は、上記の問題を解決して害獣の侵入を防止する電気柵を提供することにある。Therefore, the problem to be solved by the present invention is to provide an electric fence that solves the above-mentioned problems and prevents the invading pests.

ｈを噛み切っても、補強帯２ｇがＬ字型に折れ曲がっているので、ロープ２
ｈを持ち上げて電気柵ネット２の下を潜り抜けることができない。
（４）地表に生えた草７が上部導電帯２ｅに到達するまで漏電が起こらないので、

の侵入を躊躇する。By using an electric fence with such a configuration, the following effects occur.
(1) When the monkey climbs over the electric fence net 2 and goes over the left hand over several movements
Or keep holding the uppermost conductive rope 2d or upper conductive band 2e with your right hand
I must. The lower conductive band 2f is the number of conductive bands 2a of the conventional electric fence net 2.
Since there is a double width, the monkey will then guide the lower part with the left or right foot over several movements.
You have to keep grabbing the electric band 2f. Therefore monkeys (impact high-voltage power supply 3
Uppermost conductive rope 2d or upper conductive band 2e (connected to the positive side);
Both the lower conductive band 2f (connected to the negative side of the impact high voltage power supply 3)
It feels like it keeps touching for longer than the non-energization time (about 1 second)
It will be difficult to climb over the electric fence net 2 and get over it.
The
(2) The monkey jumps to the support column 1 to get over the electric fence and grabs the tip with his hand.
Even if you try to grab the middle part of the column 1 with your feet, the rectangle attached to the middle part of the column 1
Since the width of the board 1c is larger than the length of the monkey's foot, the monkey cannot hold the support 1 with his foot,
Conductive rope at the tip of column 1 (connected to the positive side of impact high voltage power supply 3)
2d or upper conductive band 2e and the middle part of the column 1 (the impact high voltage power source 3
Both sides of the lower conductive band 2f (connected to the eggplant side) have no impact high voltage non-energization time (about
(1 second) will continue to touch for over a period of time
It is difficult for the monkey to climb the support column 1 and get over the electric fence within the electric time.
(3) The stranded wire of the reinforcing band 2g is twisted with a thick metal wire to make it difficult for a monkey to bite it.
So it is difficult for monkeys to bite it and enter. Monkey is rope 2
Even if h is completely bitten, the reinforcing band 2g is bent in an L shape, so the rope 2
It is impossible to lift h and get under the electric fence net 2.
(4) Since no leakage occurs until the grass 7 growing on the ground surface reaches the upper conductive band 2e,
The frequency of mowing is low.
(5) Therefore, the reinforcing band 2g laid on the ground surface is often the grass 7 growing on the ground surface.
The badger finds the end of the reinforcing band 2g
It is difficult to dig into the ground and go under the reinforcing band 2g to enter the inside of the compartment.
is there. Similarly, Hakubishin finds the end of the reinforcing band 2g, the reinforcing band 2g and the ground
It is also difficult to enter the inside of the compartment through the gap.
(6) An opaque sheet like a cold chill 6 is stretched from the surface to a height of about 1 m.
So, the height of the line of sight of the cocoon is about 70cm, so this opacity sheet will make the cocoon compartment
I can't look inside. Go is a gonorrhea, so you can't see the inside because of its habit.
Hesitate to break in.
金属製パイプ１ａに長方形の板１ｃを取り付けず、（図４の断面図に示すように）内径が金属製パイプ１ａの外径より大きく、外径の半周が猿の足の長さより大きく、長方形の板１ｃと同じ長さの肉厚パイプ１ｄを、金属製パイプ１ａに差し込んで長方形の板１ｃと同じ位置に固定すれば（固定する手段は、図４に示していない。）、猿が電気柵を乗り越えようとして支柱１に飛びついて、支柱１の先端を手で掴み足でその中間部を掴もうとしても、肉厚パイプ１ｄの直径が太過ぎて猿が足で掴むことができず、乗り越えに時間がかかり過ぎて感電してしまうので、猿が支柱１をよじ登って電気柵を乗り越えることが困難となる。Without attaching the rectangular plate 1c to the metal pipe 1a, the inner diameter is larger than the outer diameter of the metal pipe 1a (as shown in the sectional view of FIG. 4), and the half circumference of the outer diameter is larger than the length of the monkey's foot. If the thick pipe 1d having the same length as that of the plate 1c is inserted into the metal pipe 1a and fixed at the same position as the rectangular plate 1c (the fixing means is not shown in FIG. 4), the monkey is electric. Even if you jump on the column 1 to get over the fence, grab the tip of the column 1 with your hand and grab the middle part with your feet, the thick pipe 1d is too thick and the monkey cannot grab with your feet, Since it takes too much time to get over the electric shock, it is difficult for the monkey to climb the support column 1 and get over the electric fence.
金属製パイプ１ａに長方形の板１ｃを取り付けず、（図５の断面図に示すように）以下のようにして支柱１の中間部の電気柵ネット２を支柱１から離隔させれば、猿が電気柵を乗り越えようとして支柱１に飛びついて、支柱１の先端を手で掴み足でその中間部を掴もうとしても、電気柵ネット２が邪魔になって猿が支柱１を足で掴むことができず、乗り越えに時間がかかり過ぎて感電してしまうので、猿が支柱１をよじ登って電気柵を乗り越えることが困難となる。
（ア） １本又は複数本の棒体１１を、直交クランプ１０のような固定器具で支柱１に区画の外側に向かって水平に固定する。
（イ） その棒体１１の先端に電気柵ネット２を固定する。（固定する手段は、図５に示していない。）If the rectangular plate 1c is not attached to the metal pipe 1a and the electric fence net 2 in the middle part of the support column 1 is separated from the support column 1 as follows (as shown in the sectional view of FIG. 5), the monkey Even if you jump over the pole 1 to get over the electric fence, grab the tip of the pole 1 with your hand and grab the middle part with your feet, the electric fence net 2 gets in the way and the monkey grabs the pole 1 with your legs It cannot be done, and it takes too much time to get over, and an electric shock is caused. Therefore, it is difficult for the monkey to climb the support column 1 and get over the electric fence.
(A) One or a plurality of rods 11 are horizontally fixed to the support column 1 toward the outside of the section with a fixing device such as an orthogonal clamp 10.
(A) The electric fence net 2 is fixed to the tip of the rod 11. (Means for fixing are not shown in FIG. 5)
以下に図面を参照して、本発明の実施の形態を説明する。図２の正面図と図３の断面図は、請求項１に記載の電気柵の実施の形態を示す。この電気柵は地表に数ｍ間隔に立設された支柱１、その支柱１に張設された電気柵ネット２、電気柵ネット２により張設された寒冷紗６のような不透明シートにより構成される。なお以下に述べる数値は一例を示すもので、これに限るものではない。Embodiments of the present invention will be described below with reference to the drawings. The front view of FIG. 2 and the cross-sectional view of FIG. 3 show an embodiment of the electric fence according to claim 1. This electric fence is composed of a column 1 erected on the ground surface at intervals of several meters, an electric fence net 2 stretched on the column 1, and an opaque sheet such as a cold chiller 6 stretched by the electric fence net 2. . In addition, the numerical value described below shows an example and is not limited to this.
支柱１は以下のような構造とする。
（１）金属製パイプ１ａの先端に絶縁物製キャップ１ｂを被せた場合に絶縁物製キャップ１ｂの下端となる位置から下方に１０ｃｍ空けて、長方形の板１ｃを、その長方形の幅を２等分する中心線が金属製パイプ１ａに接するように取り付ける。金属製パイプ１ａを鋼管とし、長方形の板１ｃを鋼板として、溶接により後者を前者に取り付けた後に全体を腐食防止のために溶融亜鉛メッキしたものが適当である。
（２）長方形の板１ｃを取り付けた金属製パイプ１ａを地表に立設し、その先端にその金属製パイプ１ａの外径より大きい内径を持つ絶縁物製キャップ１ｂを被せる。絶縁物製キャップ１ｂは塩化ビニールなどのプラスチック製とし、その長さは４０ｃｍとする。絶縁物製キャップ１ｂには電気柵ネット２の導電性ロープ２ｄを固定するので、固定した導電性ロープ２ｄが滑り落ちないように、（図３に示すように）絶縁物製キャップ１ｂの先端の直径を絞って段差をつけるとか、その表面に多数の突起や環状の突起を設けることが望ましい。支柱１の地上部の長さは、「猿がジャンプして手が届く最大の高さ（約２ｍ）」以上必要なので、金属製パイプ１ａの長さは、地上部２．０ｍ＋地中に埋設される長さ０．８ｍ＝２．８ｍ 程度である。金属製パイプ１ａをハンマーで地中に打ち込んだ後に、その先端に絶縁物製キャップ１ｂを被せることになるが、ハンマーで地中に打ち込む時に金属製パイプ１ａの先端を歪めてしまうと被せることができなくなるので、金属製パイプ１ａの先端に打ち込み用のキャップを被せて打設を行う。それでも打設時に金属製パイプ１ａの先端が歪み、打設後に打ち込み用のキャップが金属製パイプ１ａの先端から抜けなくなることがあるので、絶縁物製キャップ１ｂの内径を打ち込み用のキャップの外径より大きくしておくのが望ましい。
（３）長方形の板１ｃは猿が足で支柱１を掴み難くするための物なので、その幅は猿の足の長さ以上でなければならない。猿の足の長さのデータは公開されていないが１０ｃｍ以下と考えられるので、長方形の板１ｃの幅は余裕を見て１５ｃｍとする。長方形の板１ｃが効果を発揮するには、猿が支柱１に飛びついて絶縁物製キャップ１ｂの先端を掴んだ時、猿の足は長方形の板１ｃの下端より上に無ければならない。猿が地上に立って手を伸ばした時の手の高さを猿の身長（約９０ｃｍ）の１．２倍と仮定すると、長方形の板１ｃの長さは、
猿の身長（約９０ｃｍ）×１．２−猿が掴んだ手の位置から絶縁物製キャップ１ｂの下端までの長さ（３０ｃｍ）−絶縁物製キャップ１ｂの下端と長方形の板１ｃの上端との距離（１０ｃｍ）＝約７０ｃｍ となる。
（４）猿が支柱１に飛びついた時支柱１を掴み難くするためには、図３に示すように電気柵ネット２の面と長方形の板１ｃの面が直交するように金属製パイプ１ａを立設するのが、最も効果的と思われる。猿が支柱１に飛びつく前に、長方形の板１ｃの存在を確認し難いからである。
（５）金属製パイプ１ａの地面に打ち込む方の端を圧縮して板状にしてから、先端を鋭角に切断して尖らせ、地面に打ち込み易くするのが望ましい。
（６）金属製パイプ１ａの地面に打ち込む方の端から約８０ｃｍの位置に印をつけておき、立設作業時にはこの印まで地面に打ち込むようにすると打ち込み過ぎを防げる。The strut 1 has the following structure.
(1) When the tip of the metal pipe 1a is covered with the insulating cap 1b, the rectangular plate 1c is spaced from the lower end of the insulating cap 1b by 10 cm, and the rectangular width is set to 2 etc. The center line to be divided is attached so as to be in contact with the metal pipe 1a. The metal pipe 1a is a steel pipe, the rectangular plate 1c is a steel plate, and the latter is attached to the former by welding and then the whole is hot-dip galvanized to prevent corrosion.
(2) A metal pipe 1a to which a rectangular plate 1c is attached is erected on the ground surface, and an insulating cap 1b having an inner diameter larger than the outer diameter of the metal pipe 1a is placed on the tip. The insulating cap 1b is made of plastic such as vinyl chloride, and its length is 40 cm. Since the conductive rope 2d of the electric fence net 2 is fixed to the insulating cap 1b, the tip of the insulating cap 1b is prevented from slipping down (as shown in FIG. 3). It is desirable to provide a step by reducing the diameter, or to provide a large number of protrusions or annular protrusions on the surface. Since the length of the ground part of the support column 1 is required to be more than the “maximum height (approximately 2 m) that the monkey can jump to reach”, the length of the metal pipe 1a is embedded in the ground part 2.0 m + underground The length of 0.8 m = 2.8 m. After the metal pipe 1a is driven into the ground with a hammer, the tip of the metal cap 1b is covered with the insulator. However, if the tip of the metal pipe 1a is distorted when driven into the ground with a hammer, the metal pipe 1a may be covered. Since this is impossible, the metal pipe 1a is placed with a driving cap on the tip. Still, the tip of the metal pipe 1a may be distorted during placement, and the placement cap may not come out of the tip of the metal pipe 1a after placement. Therefore, the inner diameter of the insulator cap 1b is set to the outer diameter of the placement cap. It is desirable to make it larger.
(3) The rectangular plate 1c is a thing for the monkey to make it difficult for the monkey to hold the support column 1 with his / her foot, so the width thereof must be equal to or greater than the length of the monkey's foot. The data on the length of the monkey's foot is not disclosed, but is considered to be 10 cm or less. Therefore, the width of the rectangular plate 1c is set to 15 cm with a margin. In order for the rectangular plate 1c to be effective, the monkey's feet must be above the lower end of the rectangular plate 1c when the monkey jumps onto the support column 1 and grabs the tip of the insulating cap 1b. Assuming that the height of the hand when the monkey is standing on the ground and reaching out is 1.2 times the height of the monkey (about 90 cm), the length of the rectangular plate 1c is
Monkey height (approx. 90 cm) × 1.2—Length from the position of the hand held by the monkey to the lower end of the insulating cap 1 b (30 cm) —The lower end of the insulating cap 1 b and the upper end of the rectangular plate 1 c Distance (10 cm) = about 70 cm.
(4) In order to make it difficult for the monkey to jump to the column 1, the metal pipe 1 a is placed so that the surface of the electric fence net 2 and the surface of the rectangular plate 1 c are orthogonal as shown in FIG. 3. Standing up seems to be the most effective. This is because it is difficult to confirm the presence of the rectangular plate 1c before the monkey jumps on the column 1.
(5) It is desirable that the end of the metal pipe 1a that is driven into the ground is compressed into a plate shape, and then the tip is cut and sharpened to facilitate driving into the ground.
(6) If a mark is placed at a position about 80 cm from the end of the metal pipe 1a that is driven into the ground, and if the mark is driven to the ground up to this mark, it is possible to prevent excessive driving.
電気柵ネット２は以下のような構造とする。
（１）電気柵ネット２の高さは、「猿がジャンプして手が届く最大の高さ（約２ｍ）」以上必要なので２ｍとする。
（２）電気柵ネット２の最上部の導電性ロープ２ｄの直径は５ｍｍ程度とする。
（３）上部導電帯２ｅの幅は２０ｃｍとする。
（４）絶縁帯２ｂは衝撃高圧に対して漏電が起こらないように、上部導電帯２ｅと下部導電帯２ｆの間の絶縁を保つ働きをする。その幅は２０ｃｍとする。
（５）下部導電帯２ｆが効果を発揮するには、猿が電気柵ネット２をよじ登り、手で上部導電帯２ｅの下端を掴んだ時、猿の足が下部導電帯２ｆの下端より上に無ければならない。猿が地上に立って手を伸ばした時の手の高さを猿の身長（約９０ｃｍ）の１．２倍と仮定すると、下部導電帯２ｆの幅は、
猿の身長（約９０ｃｍ）×１．２−絶縁帯２ｂの幅（２０ｃｍ）＝約９０ｃｍ となるので、余裕を見て１ｍとする。
（６）補強帯２ｇをＬ字型に折り曲げて半分の幅は鉛直に張設し、残りの半分の幅は区画の外側の地表に敷設する。補強帯２ｇの鉛直部分の幅は、
電気柵ネット２の高さ（２ｍ）−上部導電帯２ｅの幅（２０ｃｍ）−絶縁帯２ｂの幅（２０ｃｍ）−下部導電帯２ｇの幅（１ｍ）＝６０ｃｍ
となる。したがって電気柵ネット２の幅は２．６ｍになる。
（７）網目の形状である正方形や菱形の１辺の長さを網目の大きさと定義すれば、上部導電帯２ｅ、絶縁帯２ｂ、下部導電帯２ｆの網目の大きさは、ハクビシンが通過できないように１０ｃｍ以下が望ましい。補強帯２ｇの網目の大きさは、１箇所喰いちぎられただけではハクビシンが通過できないように、５ｃｍ以下が望ましい。The electric fence net 2 has the following structure.
(1) The height of the electric fence net 2 is 2 m because it is required to be equal to or greater than the “maximum height (approximately 2 m) that a monkey can jump and reach”.
(2) The diameter of the uppermost conductive rope 2d of the electric fence net 2 is about 5 mm.
(3) The width of the upper conductive band 2e is 20 cm.
(4) The insulating band 2b functions to maintain insulation between the upper conductive band 2e and the lower conductive band 2f so that no leakage occurs due to impact high voltage. The width is 20 cm.
(5) For the lower conductive band 2f to be effective, when the monkey climbs the electric fence net 2 and grasps the lower end of the upper conductive band 2e by hand, the monkey's foot is above the lower end of the lower conductive band 2f. There must be. Assuming that the height of the hand when the monkey stands on the ground and extends his hand is 1.2 times the height of the monkey (about 90 cm), the width of the lower conductive band 2f is
Since the height of the monkey (about 90 cm) × 1.2−the width of the insulating band 2 b (20 cm) = about 90 cm 2, the margin is set to 1 m.
(6) The reinforcing band 2g is bent into an L shape, and half the width is stretched vertically, and the remaining half width is laid on the ground surface outside the section. The width of the vertical part of the reinforcing band 2g is
Height of electric fence net 2 (2 m) -width of upper conductive band 2e (20 cm) -width of insulating band 2b (20 cm) -width of lower conductive band 2g (1 m) = 60 cm
It becomes. Therefore, the width of the electric fence net 2 is 2.6 m.
(7) If the length of one side of a square or rhombus that is the shape of the mesh is defined as the size of the mesh, the mesh size of the upper conductive band 2e, the insulating band 2b, and the lower conductive band 2f cannot pass the hakubishin. Thus, 10 cm or less is desirable. The size of the mesh of the reinforcing band 2g is desirably 5 cm or less so that the hakubicin cannot pass only by being bitten at one place.
電気柵ネット２を支柱１に以下のように張設する。
（１）補強帯２ｇをＬ字型に折り曲げて半分の幅は鉛直に張設し、残りの半分の幅は区画の外側の地表に敷設するので、区画の内側に支柱１が存在するように電気柵ネット２を支柱１に張設する。
（２）上部導電帯２ｅが絶縁物製キャップ１ｂのみに接触し金属製パイプ１ａに接触しないように、導電性ロープ２ｄを絶縁物製キャップ１ｂに固定する。絶縁物製キャップ１ｂの長さを４０ｃｍ、上部導電帯２ｅの幅を２０ｃｍとすると、絶縁物製キャップ１ｂの先端から１０ｃｍ以内の位置に導電性ロープ２ｄを固定する。図３のように絶縁物製キャップ１ｂの先端の直径を絞って段差をつける場合は、先端から１０ｃｍ以内の位置で段差をつける。
（３）下部導電帯２ｆを支柱１の金属製パイプ１ａに固定する。この固定により下部導電帯２ｆと金属製パイプ１ａを電気的に接続するので、両者がある程度の圧力で接触するように、下部導電帯２ｆを金属製パイプ１ａに結束バンドなどで緊縛する。
（４）補強帯２ｇが地面に到着したらＬ字型に折り曲げて、補強帯２ｇのおよそ半分の幅の部分を支柱１に張設し、残りのおよそ半分の幅の部分を区画の外側の地表に敷設する。支柱１が地表に一直線に並んでいる場合は敷設に問題は無いが、（図６の斜視図に示すように）地表に補強帯２ｇを固定しているロープ２ｈを考えると、そのロープ２ｈがある支柱１で（区画の内側から見て）１８０度以下の角度で曲がっている場合は、その支柱１付近では地表に敷設する補強帯２ｇの長さが不足するため、補強帯２ｇは長さ方向に延びて幅方向に縮む。すなわち支柱１が地表に一直線に並んでいる場合は地表を覆う補強帯２ｇの網目は正方形だが、この場所では補強帯２ｇの長さ方向に延びた菱形になる。補強帯２ｇが幅方向に縮んだことで覆えなくなった地表は、図６のように金網８で覆って補い、その金網８を留め具４で地表に固定する。（図６には留め具４は示していない。）金網８の網目の大きさは、補強帯２ｇの網目の大きさに近い方がよい。
（５）補強帯２ｇの幅方向の中央にあるロープ２ｈを、地表に数十ｃｍの間隔で留め具４により固定する。従来のネット式電気柵のようにこの固定によって害獣の潜り抜けを防ぐのではなく、単に補強帯２ｇが草の繁茂によって地面から浮き上がらないように固定するだけだから、留め具４の長さは２０ｃｍ程度とする。
（６）末端のロープ２ｃを、地表に数十ｃｍの間隔で留め具４により固定する。上記と同じ理由で、留め具４の長さは２０ｃｍ程度とする。
（７）電気柵を設置する前に地表の草を刈っておけば、その後草の芽は地表に敷設された補強帯２ｇの網目を通ってから枝葉を広げるから、草７は補強帯２ｇを持ち上げずに補強帯２ｇを覆い隠すので好都合である。しかし草刈り直後は補強帯２ｇがむき出しになるので、刈った草で覆って見えないようにする。なおアナグマが地表にある補強帯２ｇの末端を見分け難いように、補強帯２ｇや末端のロープ２ｃの色を地面と同じ色にするのは効果が期待できる。The electric fence net 2 is stretched on the column 1 as follows.
(1) The reinforcing band 2g is bent into an L-shape, and the half width is stretched vertically, and the remaining half width is laid on the ground surface outside the section, so that the column 1 exists inside the section. The electric fence net 2 is stretched on the column 1.
(2) The conductive rope 2d is fixed to the insulator cap 1b so that the upper conductive band 2e contacts only the insulator cap 1b and does not contact the metal pipe 1a. When the length of the insulating cap 1b is 40 cm and the width of the upper conductive band 2e is 20 cm, the conductive rope 2d is fixed at a position within 10 cm from the tip of the insulating cap 1b. When the step is made by reducing the diameter of the tip of the insulating cap 1b as shown in FIG. 3, the step is made at a position within 10 cm from the tip.
(3) The lower conductive band 2 f is fixed to the metal pipe 1 a of the column 1. Since the lower conductive band 2f and the metal pipe 1a are electrically connected by this fixing, the lower conductive band 2f is bound to the metal pipe 1a with a binding band or the like so that they are in contact with each other with a certain pressure.
(4) When the reinforcing band 2g arrives on the ground, it is bent into an L shape, and the half-width portion of the reinforcing band 2g is stretched on the support column 1, and the remaining half-width portion is grounded outside the section. Lay in. There is no problem in laying when the support columns 1 are aligned in a straight line on the ground surface (as shown in the perspective view of FIG. 6), but considering the rope 2h fixing the reinforcing band 2g to the ground surface, the rope 2h When a certain strut 1 is bent at an angle of 180 degrees or less (as viewed from the inside of the section), the length of the reinforcing band 2g laid on the ground surface is short in the vicinity of the strut 1, so the reinforcing band 2g is long. It extends in the direction and shrinks in the width direction. That is, when the pillars 1 are aligned with the ground surface, the mesh of the reinforcing band 2g covering the ground surface is a square, but at this place, a rhombus extending in the length direction of the reinforcing band 2g is formed. The ground surface that cannot be covered by the reinforcement band 2g being shrunk in the width direction is covered with a wire mesh 8 as shown in FIG. 6 and the wire mesh 8 is fixed to the ground surface with a fastener 4. (The fastener 4 is not shown in FIG. 6) The mesh size of the wire mesh 8 should be close to the mesh size of the reinforcing band 2g.
(5) The rope 2h at the center in the width direction of the reinforcing band 2g is fixed to the ground surface with a fastener 4 at intervals of several tens of centimeters. This fixing does not prevent the pests from passing through like conventional net type electric fences, but the fixing band 2g is simply fixed so that it does not rise from the ground due to the overgrowth of grass. About 20 cm.
(6) The rope 2c at the end is fixed to the ground surface with a fastener 4 at intervals of several tens of centimeters. For the same reason as described above, the length of the fastener 4 is about 20 cm.
(7) If you cut the grass on the surface before installing the electric fence, then the grass buds will spread the branches and leaves through the mesh of the reinforcing band 2g laid on the surface. This is advantageous because it covers the reinforcing band 2g without lifting it. However, since the reinforcing band 2g is exposed immediately after mowing, it is covered with the mowing grass so that it cannot be seen. In order to make it difficult for the badger to distinguish the end of the reinforcing band 2g on the ground surface, it can be expected that the color of the reinforcing band 2g and the end rope 2c is the same color as the ground.
寒冷紗６のような不透明シートを結束バンドなどで電気柵ネット２に固定し、区画の内側に地表から１ｍ程度の高さまで張設する。寒冷紗には５０％遮光、７０％遮光、９０％遮光などの種類があるが、９０％遮光が最適である。An opaque sheet such as a cold tub 6 is fixed to the electric fence net 2 with a binding band or the like, and is stretched to a height of about 1 m from the ground surface inside the compartment. There are various types of cold smoke, such as 50% light shielding, 70% light shielding, 90% light shielding, and 90% light shielding is optimal.
電気柵ネット２の導電性ロープ２ｄを衝撃高圧電源３のプラス側に、地中に打ち込んだ接地極５を衝撃高圧電源３のマイナス側に接続する。衝撃高圧電源３のプラス側の配線は、ネオン電線のように高電圧に耐えられる電線を使用する。The conductive rope 2d of the electric fence net 2 is connected to the plus side of the impact high-voltage power source 3, and the ground electrode 5 driven into the ground is connected to the minus side of the impact high-voltage power source 3. For the plus-side wiring of the impact high-voltage power supply 3, an electric wire that can withstand a high voltage such as a neon electric wire is used.
草刈り時にチップソー式草刈り機を使うと、草刈り機の刃が電気柵ネット２に触れた時に切断してしまうので、ナイロンコード式草刈り機を使うべきである。また草刈り機のナイロンコードにより寒冷紗６のような不透明シートが損傷されないように、予め地表から２０ｃｍ程度の高さに下端が来るように張設しておくほうが良い。猪の視点の高さは約７０ｃｍなので、このように張設しても猪は依然として区画の内側を見ることができずその効果に変わりはない。If a tip saw mower is used when mowing, the blade of the mower will cut when it touches the electric fence net 2, so a nylon cord mower should be used. In addition, it is better to stretch in advance so that the lower end comes to a height of about 20 cm from the ground surface so that the opaque sheet such as the cold chiller 6 is not damaged by the nylon cord of the mower. Since the height of the eyelid's viewpoint is about 70 cm, even if it is stretched in this way, the eyelid still cannot see the inside of the compartment and its effect remains the same.
区画の外側の草７を刈る場合、草７を根元から刈ると地表を覆っている補強帯２ｇに草刈り機のナイロンコードが触れて、補強帯２ｇがめくれてしまう。地表から２０ｃｍ程度の高さで刈るようにすれば、ナイロンコードが地表を覆っている補強帯２ｇに触れないので上記のトラブルを防げる。また補強帯２ｇの網目の大きさは５ｃｍ以下なので、草刈り機のナイロンコードは区画の内側にある寒冷紗６のような不透明シートに触れてこれを損傷することは無く、鉛直に張設した補強帯２ｇのみに触れる。しかしながら補強帯２ｇの撚線には太い金属線が撚り込んであるので、草刈り機のナイロンコードによって損傷を受けることは無い。When the grass 7 outside the section is cut, when the grass 7 is cut from the base, the nylon cord of the mower touches the reinforcing band 2g covering the ground surface, and the reinforcing band 2g is turned up. If it is made to cut at a height of about 20 cm from the ground surface, the nylon cord does not touch the reinforcing band 2g covering the ground surface, so the above trouble can be prevented. In addition, since the mesh size of the reinforcing band 2g is 5 cm or less, the nylon cord of the mower does not touch the opaque sheet such as the cold chiller 6 inside the compartment and damages it, and the reinforcing band 2g stretched vertically. Touch only. However, since the thick metal wire is twisted into the stranded wire of the reinforcing band 2g, it is not damaged by the nylon cord of the mower.
区画の内側の草７を刈る場合、草７を根元から刈るようにする。草７を根元から刈れば、草刈り機のナイロンコードは２０ｃｍ以上の高さにある寒冷紗６のような不透明シートに触れてこれを損傷することは無く、鉛直に張設した補強帯２ｇのみに触れる。When the grass 7 inside the section is cut, the grass 7 is cut from the root. If the grass 7 is cut from the root, the nylon cord of the mower does not touch and damage the opaque sheet such as the cold tub 6 at a height of 20 cm or more, and touches only the reinforcing band 2g stretched vertically.
図７のように、地表に草が生えることを防止する防草シートを電気柵と組み合わせて敷設すれば、草７は電気柵から防草シートの幅だけ離れた場所にしか生えないので、草刈り機により電気柵ネット２や寒冷紗６のような不透明シートに損傷を与えることは無くなる。まず区画の外側の地表を幅３０ｃｍ、区画の内側の地表を幅６０ｃｍで覆うように防草シート（以後この防草シートを「内側の防草シート９ａ」と呼ぶ。）を敷設してから、請求項１に記載の電気柵を設置する。その後区画の外側の地表を幅９０ｃｍで覆うように防草シート（以後この防草シートを「外側の防草シート９ｂ」と呼ぶ。）を敷設すれば、区画の外側の地表に敷設された補強帯２ｇは外側の防草シート９ｂに覆われてしまうので、アナグマが補強帯２ｇの末端を見つけて、そこから地面を掘って補強帯２ｇの下を潜り抜け区画の内側に侵入するのは困難である。As shown in Fig. 7, if a grass protection sheet that prevents grass from growing on the ground surface is laid in combination with an electric fence, the grass 7 can only grow away from the electric fence by the width of the grass protection sheet. As a result, the non-transparent sheet such as the electric fence net 2 and the cold water bottle 6 is not damaged. First, after laying a weedproof sheet (hereinafter referred to as “inner weedproof sheet 9a”) so as to cover the outer surface of the section with a width of 30 cm and the inner surface of the section with a width of 60 cm, The electric fence according to claim 1 is installed. After that, if a weedproof sheet (hereinafter referred to as "outer weedproof sheet 9b") is laid so as to cover the ground surface outside the section with a width of 90 cm, the reinforcement laid on the ground surface outside the section Since the band 2g is covered with the outer grass protection sheet 9b, it is difficult for the badger to find the end of the reinforcing band 2g and dig out of the ground from there to penetrate under the reinforcing band 2g and enter the inside of the section. It is.
図４の断面図は、請求項２に記載の電気柵の実施の形態を示す。肉厚パイプ１ｄとしては、凍結防止用水道パイプが適当である。凍結防止用水道パイプは、ポリエチレン製パイプを発泡ウレタンで覆い、外側をポリエチレン被覆で包んだものである。猿の足の長さを１０ｃｍと仮定すれば、肉厚パイプ１ｄの直径は６．４ｃｍ以上となるので、余裕を見て１０ｃｍ程度とする。肉厚パイプ１ｄの長さは、長方形の板１ｃと同じく７０ｃｍとする。なお段落００１０の（２）に述べたと同じ理由で、肉厚パイプ１ｄの内径は、金属製パイプ１ａを打設する時の打ち込み用キャップの外径より大きくしておくのが望ましい。The cross-sectional view of FIG. 4 shows an embodiment of the electric fence according to claim 2. As the thick pipe 1d, a water pipe for preventing freezing is suitable. The anti-freezing water pipe is a polyethylene pipe covered with foamed urethane, and the outside is wrapped with polyethylene. If the length of the monkey's foot is assumed to be 10 cm, the diameter of the thick pipe 1d is 6.4 cm or more. The length of the thick pipe 1d is 70 cm, the same as the rectangular plate 1c. For the same reason as described in paragraph 0010 (2), it is desirable that the inner diameter of the thick pipe 1d be larger than the outer diameter of the driving cap when the metal pipe 1a is driven.
図５の断面図は、請求項３に記載の電気柵の実施の形態を示す。棒体１１としては、溶融亜鉛メッキした鋼管が適当である。支柱１の中間部において、電気柵ネット２を支柱１から最大で２０ｃｍ程度離隔させる。棒体１１に電気柵ネット２を固定する手段（図５には示していない。）としては、既存の電線式電気柵において裸電線を絶縁物製の支柱に固定する電線式電気柵用クリップが適当である。The cross-sectional view of FIG. 5 shows an embodiment of an electric fence according to claim 3. As the rod 11, a hot-dip galvanized steel pipe is suitable. In the middle part of the support column 1, the electric fence net 2 is separated from the support column 1 by about 20 cm at the maximum. As a means for fixing the electric fence net 2 to the rod 11 (not shown in FIG. 5), there is a wire electric fence clip for fixing a bare electric wire to an insulating column in an existing electric wire electric fence. Is appropriate.
段落００１０の（２）で述べたように、支柱１の金属製パイプ１ａの長さは２．８ｍ程度となるので、ハンマーを使って打設するのは困難である。しかしながら図８のように支柱１を二重管構造にすればその立設が容易となる。すなわち打設の容易な短い金属製パイプ１ｅをまず打設し、その短い金属製パイプ１ｅにその外径より大きい内径を持つ金属製パイプ１ａを差し込めばよい。支柱１の金属製パイプ１ａの地上部の長さが２．０ｍ程度の場合は、金属製パイプ１ｅの長さは、 地上部１ｍ＋地中部０．８ｍ＝１．８ｍ 程度となる。これは、ハンマーを使って容易に打設できる長さである。支柱１を二重管構造にすると、金属製パイプ１ａは地中に打ち込まれていないので、下部導電帯２ｆを金属製パイプ１ａに固定しても下部導電帯２ｆが衝撃高圧電源３のマイナス側に接続されたことにはならない。そこで新たに接地極５を地中に打ち込んで、その接地極５と下部導電帯２ｆを配線で接続しなければならない。金属製パイプ１ｅについては、以下のようにするのが望ましい。
（１）地面に打ち込み易いように、金属製パイプ１ｅの先端を圧縮して板状にしてから鋭角に切断して尖らせておく。
（２）金属製パイプ１ｅの地面に打ち込む方の端から約８０ｃｍの位置に印をつけておき、立設作業時にはこの印まで地面に打ち込むようにすると打ち込み過ぎを防げる。
（３）金属製パイプ１ｅをハンマーで地中に打ち込む時にその先端を歪めてしまうと金属製パイプ１ａの差し込みができなくなるので、金属製パイプ１ｅの先端に打ち込み用のキャップを被せて打設を行う。それでも打設時に金属製パイプ１ｅの先端が歪み、打設後に打ち込み用のキャップが金属製パイプ１ｅの先端から抜けなくなることがあるので、金属製パイプ１ａの内径を打ち込み用のキャップの外径より大きくしておく。As described in paragraph (0010) of paragraph 0010, the length of the metal pipe 1a of the support column 1 is about 2.8 m, so that it is difficult to drive using a hammer. However, if the support column 1 has a double tube structure as shown in FIG. That is, a short metal pipe 1e that is easy to be placed is first placed, and a metal pipe 1a having an inner diameter larger than the outer diameter is inserted into the short metal pipe 1e. When the length of the ground part of the metal pipe 1a of the support column 1 is about 2.0 m, the length of the metal pipe 1e is about 1m above the ground part + 0.8 m = underground part = 1.8 m. This is a length that can be easily placed using a hammer. When the support column 1 has a double pipe structure, the metal pipe 1a is not driven into the ground, so even if the lower conductive band 2f is fixed to the metal pipe 1a, the lower conductive band 2f remains on the negative side of the impact high voltage power source 3. It is not connected to. Therefore, a new ground electrode 5 must be driven into the ground, and the ground electrode 5 and the lower conductive band 2f must be connected by wiring. The metal pipe 1e is preferably as follows.
(1) The tip of the metal pipe 1e is compressed into a plate shape and then cut into an acute angle and sharpened so as to be easily driven into the ground.
(2) If a mark is placed at a position of about 80 cm from the end of the metal pipe 1e that is driven into the ground, and it is driven to the ground up to this mark during standing work, excessive driving can be prevented.
(3) Since the metal pipe 1a cannot be inserted if the tip of the metal pipe 1e is distorted when the metal pipe 1e is driven into the ground with a hammer, the tip of the metal pipe 1e is covered with a driving cap. Do.
