PROBLEM TO BE SOLVED: To provide an electric fence that prevents invasion of a monkey, and also prevents entry of a wild boar, a badger and a palm civet, and thereby prevents the monkey and the palm civet from invading from the place where the wild boar and the badger invade.SOLUTION: (1) When a monkey gets over an electric fence, the monkey is made to continue touching over the time of a non-energization time or more to a conduction band of an electric fence net 2 connected to the positive side of a shock high voltage power supply 3, and a conduction band connected to the negative side. (2) A rectangular plate 1c is attached to a strut 1, and the monkey is made to be hard to get the strut 1. (3) Metal wire is twisted in the bottommost mesh of the electric fence net 2, and cannot be broken by the monkey. (4) The bottommost mesh of the electric fence net 2 is laid on the outside surface of the earth of the electric fence, and it is covered with grass 7, and thereby the badger and the palm civet are prevented from coming through the bottom of the electric fence. (5) A cheesecloth 6 is stretched from the surface of the earth to the height of 1 m in the electric fence net 2, and the wild boar is made to hesitate to invade to the place where the inside is not seen according to the behavior of the wild boar. (6) The shock high voltage is applied only to the topmost conduction band of the electric fence net 2.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】猿の侵入を防止しかつ猪、アナグマ、ハクビシンの侵入も防止して、猪やアナグマの侵入した箇所から猿やハクビシンが侵入しない電気柵を提供する。【解決手段】(1)猿が電気柵を乗越える時に、衝撃高圧電源3のプラス側に接続された電気柵ネット2の導電帯と、マイナス側に接続された導電帯に、非通電時間以上の時間に亘って触れ続けるようにする。(2)支柱1に長方形の板1cを取付けて、猿が支柱1を掴み難くする。(3)電気柵ネット2の最下部の網に金属線を撚り込み、猿が噛み切れなくする。(4)電気柵ネット2の最下部の網を電気柵の外側の地表に敷設し、それが草7で覆われるようにして、アナグマやハクビシンが電気柵の下を潜り抜けるのを防ぐ。(5)電気柵ネット2に地表から1mの高さまで寒冷紗6を張設し、猪の習性により内側が見えない場所への侵入を躊躇させる。(6)電気柵ネット2の最上部の導電帯のみに衝撃高圧を印加する。【選択図】図3
