Description

  The present invention relates to a support column that supports an electric fence installed to prevent invasion of harmful animals.

  In recent years, with the increase in the number of wild animals such as wild boars, monkeys and deer, and changes in habitats, so-called food damage that eats crops such as fields and orchards has become a major social problem. In addition, animals invade mountains, ranches, and golf courses, causing various damage.

  Various methods have been employed in the past to prevent such damage caused by harmful animals. A typical method is to dispel animals by making them feel pain by an electric shock called an electric fence. There is. This is because a high-voltage pulse voltage is applied to the bare wires supported by the pillars, each connected to the plus or minus electrode, and the animals touching the plus and minus poles of these bare wires are affected by electric shock. It is dissipated by feeling pain and prevents invasion.

  In this way, the method of dispelling harmful animals by giving pain due to electric shock not only has the effect of feeling pain and dispelling, but also has the effect of becoming inaccessible due to the learning effect due to frequent pain, Recently, it is often used because it is easy to install and operate and its cost is relatively low.

  As shown in FIG. 28, such an electric fence includes a bare wire connected to the ground (earth) and the plus electrode, or a bare wire connected to the minus electrode and a bare wire connected to the plus electrode. In order to obtain the electrical insulation, the support 1 and the insulator 2 having electrical insulation are used. The support column 1 uses a steel pipe whose surface is coated with an electrically insulating synthetic resin, a synthetic resin rod, or the like. In many cases, the insulator 2 is composed of a portion for fixing to the support column 1 and a portion for providing a groove for preventing creeping discharge and a wire for winding or hooking the bare electric wire 3. An insulating insulator 2 is fixed to the column 1 toward the side from which the cage 4 and other animals enter, and the bare wire 3 is wound around or hooked on the groove portion 5 of the insulator 2.

  Although it is an electric fence constructed as described above, animals with high jumping power, such as deer, and animals with high climbing ability, such as monkeys, jump over electric fences, nets, etc. May invade. Therefore, in order to prevent such a situation, a method has been proposed in which a return member is provided on the upper part (Patent Document 1) and a column is extended (Patent Document 2).
