Description

  The present invention relates to an electric fence that repels pests such as wild boar with high-voltage current.

  In the conventional electric fence, for example, as shown in Patent Document 1, a field or a field is surrounded by a bare electric wire, and a high-voltage current always flows.

JP 2011-167104 A JP 2012-254043 A

As described above, when a high-voltage current is continuously applied, even if a plant such as grass or rice is touched, even if a slight current flows, it continues to flow for a long time, so that the electricity of the battery is discharged and cannot be stored.
As shown in Patent Document 2, there is an invention in which a high voltage current flows only when a pest touches an electric fence, but an accessory device related to a touch sensor is necessary and expensive.

  In order to solve the above-mentioned problem, the present invention is an electric fence for repelling pests, and a plurality of struts erected at a predetermined interval, and a pulley having an insulating performance attached to each of the struts. A bare wire continuously stretched between, a power supply for supplying a high-voltage current to the bare wire, a ground rod connected to the power supply and driven into the ground, and a harmful animal touching the bare wire And a power switch device for supplying a high voltage current from the power supply device to the bare wire intermittently for a certain time.

At one of the two pillars, the end of the bare wire is stopped with an insulator at the height where the pest touches, and a pulley made of several insulators is attached on the same height of the opposite pillar, and A case like a tea tube with a weight is hung from the pulley on the column via the pulley to the end of the bare wire, which is 15 centimeters below, and the inner surface of the case serves as a guide and the weight serves as a spring. A contact is provided in the center of the bottom of this weight, and the small spring contact that becomes an electrode from the bottom of the case is stopped by an insulator without contacting the weight contact, and is pulled by the case containing the weight. When a harmful animal touches the bare wire, the case is pulled up through the pulley, the weight supported by the spring is inertial, and the spring shrinks and rises late, so it stops with an insulator in the middle of the case bottom Small spring contact and bottom contact of weight High-voltage current flows in the bare contact, weight is repeated up and down swinging a spring, a power switch device that flows high-voltage current is several times bare.
Instead of constantly passing a high-voltage current through the bare wire, it will only flow for 4-5 seconds intermittently when a pest such as a boar touches the bare wire.

Because high voltage current flows intermittently for several seconds only when a pest touches, without always flowing high voltage current.
(1) The life of the battery becomes very long because there is no discharge even if the plant touches the bare wire.
(2) It can be grounded even in places where wild animals such as wild boars, bears and monkeys descend, or where plants may touch the bare lines along the road.
(3) Battery capacity and solar battery charging may be small.
(4) Easy grounding even in small farms (5) Even if a person grasps it by mistake, it is released because the high-voltage current is intermittently turned on and off.
(6) Even if the grass around the bare wire is not frequently cut, it may be cut before the harmful effect is reduced on the pests.

Embodiment 1
The power switch device 4 according to claim 1 or 2 is provided with an electrode 1 for a bare wire 12 on an upper side of a substantially sealed conductive cylindrical case 2 and an electrode 7 attached in an insulated state from the case 2 on a lower side. A weight 3 that can swing up and down supported by a spring 6 housed in a guide, an inner surface of the case 2, a contact 5 attached to the center of the bottom of the weight 3, and the contact 5. The contact made by the vertical swing of the weight 3 in the case 2 that is interlocked with the vertical swing of the entire power switch device 4 when the pest touches the bare wire 12. An electric fence for repelling pests, characterized in that high voltage current is intermittently supplied to the bare wire 12 by intermittent contact between the small electrode spring 7 and the small electrode spring 7.

Embodiment 2
Attach the bare wire 12 to one pillar 10 with an insulator 13 at a height where the harmful animal touches, and use several pulleys 11 made of the insulator so that the bare wire 12 can be stretched parallel to the ground. 10, the lower pulley 11 and the upper pulley 11 are attached, the bare wire 12 is hung from the lower pulley 11 to the upper pulley 11, and the bare wire at a position lower than the pulley 11 on the support column 10 by several tens of centimeters. The conductive cylindrical case 2 containing the weight 3 is suspended by a fastening screw at the end of 12 and this weight 3 is supported by a spring 6 from the bottom with the inner surface of the case 2 like a brown tube as a guide. In the middle of the bottom of 2, a small spring 7 that becomes an electrode is attached to the contact 5 at the bottom of the weight 3 with an insulator (plastic or the like) to the extent that it does not come in contact with a bolt and nut 8. When touching 12, bare wire 12 is pulled The case 2 containing the weight 3 is pulled upward via the pulley 11 so that the light case 2 rises first, the spring 6 supporting the weight 3 with mass is shrunk, and the small electrode spring 7 is placed at the bottom of the weight 3. A harmful animal in which a high voltage current flows through the bare wire 12 for the first time when it contacts the contact 5, and is repeatedly swung up and down several times by the inertia of the spring 6 and the weight 3, and the high voltage current flows intermittently through the bare wire 12. Repel electric fence.
