Description

  The present invention relates to an electric fence post and an electric fence. Specifically, for example, it relates to an electric fence post and an electric fence for protecting a field from wild animals.

  In rural areas in mountainous areas, electric fences are often used to prevent wild animals such as deer, foxes, monkeys and bears from entering the fields.

  The electric fence is applied to the bare wire laid around the field, and the voltage generated from the voltage generation circuit in the power supply device is applied to repel the wild animal that touched the bare wire by electric shock of the applied voltage. The fence.

FIG. 7 shows a conventional electric fence.
As shown in FIG. 7, the conventional electric fence 100 includes a bare electric wire (103a to 103d) that is stretched by being locked to an insulator (103a to 103d) attached to a support column 102 placed around the field. Is provided.

  Further, the bare wires (103a to 103d) are connected by the upper and lower connections 104 made of bare wires every about 50 m.

  Further, among the bare wires (103a to 103d), the first bare wire 103d closest to the ground surface is located at a height of about 20 cm from the ground surface, and the second bare wire 103c is from the bare wire 103d. The third stage bare electric wire 103b is located at a height of about 40 cm upward from the bare electric wire 103c, and the fourth stage bare electric wire 103a is arranged from the bare electric wire 103b. It is located at a height of about 50 cm upward.

  A power supply device 105 having a voltage generation circuit that generates a predetermined voltage applied to the stretched bare wires (103a to 103d) is electrically connected to the bare wire 103c.

When a wild animal comes into contact with a stretched bare wire (103a to 103d) in an attempt to invade a field surrounded by the electric fence 100, the wild animal is shocked to animals, humans, and the like. High current (impact current) flows as much as possible.
At this time, as shown by the arrows in FIG. 7, the impact current includes the output terminal 106 of the power supply device 105, the output line 107 of the power supply device 105, the bare wire 103c, the vertical connection 104, the bare wires (103a, 103b and 103d), deer, etc. The wild animal 108, the underground 109, the earthing rod 110, the earthing wire 111, and the earthing terminal 112 flow through the route.

  As a result, the wild animal 108 is repulsed by receiving an electric shock.

Moreover, as a support | pillar used for such an electric fence, patent document 1 describes the support | pillar for electric fences as shown in FIG.
That is, the electric fence post 100 described in Patent Document 1 includes a columnar column main body 110 made of synthetic resin, a hook portion 111 provided on the surface of the column main body 110, and a circumferential surface of the column main body 110.

  However, although a voltage is applied to the bare wire of the electric fence, the pole has insulation, so the monkey can climb over the electric fence by grabbing the pole with his hand without touching the bare wire. There is a problem that a bear or a spider intrudes into the field by pushing down the support without touching the bare wire.

  Moreover, the conventional electric fence has a structure in which an insulator and a bare electric wire are attached to protrude from one side of a support column. In this case, it is easy to get an electric shock when a wild animal approaches the support from the side where the insulator or bare wire protrudes, but when the wild animal approaches the support from the side opposite to the side where the insulator protrudes, contact the bare wire. It is difficult to touch the column without electric shock.

  In general, an electric fence is installed by protruding an insulator or a bare electric wire toward the outside of the field in order to prevent wild animals from entering the field. However, this structure has a problem that it is easy for a wild animal that has once entered the field for some reason to escape from the field without electric shock. In particular, animals that can climb, such as monkeys, may enter by jumping over an electric fence from a three-dimensional building or tree adjacent to the field. There is a problem that the effect of the electric fence disappears after learning to climb and escape.

[Electric fence]
FIG. 6 is a schematic view showing an example of an electric fence to which the present invention is applied.
The electric fence 31 of the present invention shown in FIG. 6 includes the electric fence post 1 according to the first embodiment of the present invention that is erected around the field.

Moreover, the electric fence 31 of the present invention includes four bare electric wires 6 stretched in parallel with each other on the electric fence post 1 of the present invention.

The member support itself can also be charged with electricity flowing through the conductive member.

  In addition, the electric fence post of the present invention can be mounted on the surface of the post body and has a conductive part having conductivity, so it is attached to one conductive member support part attached to the post body and the post body. It is possible to energize between the other conductive member support portions.

Therefore, since the electric fence post of the present invention is electrocuted even if a wild animal touches the main body of the pole, it is easy to cause an electric shock to the wild animal when used in the electric fence.
Moreover, the electric fence of this invention provided with the support | pillar for electric fences of this invention is also easy to make a wild animal receive an electric shock.

  In addition, since the electric fence post of the present invention receives an electric shock even when a wild animal touches the main body of the post, the ease of electric shock does not change from one side or the other side of the post.

Therefore, the electric fence post of the present invention can establish repelling learning for the wild animal.
