Description

Detailed description of the invention

The present invention relates to an electric fence that is repelled by installing a conductive net around the field and applying shock high voltage to the conductive part to cause electric shock to harmful beasts such as monkeys, foxes and hakubishin. It is.

In recent years, in the fields of mountainous areas, damage caused by invading beasts such as monkeys, rabbits, and hakubishin has frequently occurred. Therefore, electric fences have been installed around the crops in the fields. The electric fence is installed by installing a conductive net around the field and applying an impact high voltage to the conductive part to repel it by causing an electric shock to the invading beast.

As shown in FIG. 1, the electric fence has a net 4 in which insulating bands 2 and conductive bands 3 are alternately arranged by an upright insulating support column 1 around the field. An impact high voltage of 6,000 V to 7,000 V generated from the impact high voltage power source 5 is applied.

In FIG. 2, when a beast such as cocoon 6 touches the conductive band 3 of the stretched net 4 in an attempt to enter the field, as indicated by the arrow, the impact high voltage power source 5 → the conductive band 3 of the net 4 → 猪 6 → An impact current flows along the route of ground surface 7 → ground bar 8 → impact high-voltage power source 5 and the rod 6 is electrocuted.

However, when grass grows on the ground surface 7 below the conductive band 3 and comes into contact with the conductive band 3, a leakage current flows through the grass, so that the impact voltage applied to the conductive band 3 is reduced. Can no longer flow. In order to prevent this, it is necessary to cut the grass below the conductive band 3, but the distance between the surface 7 and the conductive band 3 is about 20cm, so we cut grass every two weeks in the summer when the grass grows fast. Must.

An effective means for preventing grass from growing on the ground surface 7 below the conductive band 3 is to lay a grass protection sheet 9 on the ground surface 7 as shown in FIG. The herbicidal sheet 9 is a sheet made by weaving chemical fibers, and it prevents the growing grass buds from passing through the herbicidal sheet 9 and blocks sunlight from interfering with photosynthesis. Can suppress the growth of grass.

However, since the weedproof sheet 9 is made by weaving chemical fibers, it itself is an electrical insulator. As shown in FIG. 3, when the kite 6 gets on the grass protection sheet 9, the kite 6 is electrically insulated from the ground surface 7. Since the shock current does not flow in the direction, the fence 6 does not receive an electric shock, and the original purpose of the electric fence cannot be achieved.

Therefore, the problem to be solved by the present invention is to suppress the growth of grass under the electric fence net 4 by the grass protection sheet 9 in the electric fence for the purpose of preventing the invasion of harmful beasts such as rabbits and monkeys into the field. Thus, it is an object of the present invention to provide an electric fence that can greatly reduce the labor required for mowing, and that allows the impact current generated from the impact high-voltage power supply 5 to pass through the body of the harmful animal and effectively impact the harmful animal.

As shown in FIG. 4, a conductive band 3 is provided at the lowermost part, and an insulator 2 and a conductive band 3 are alternately arranged on the upper part of the conductive band 3 to form an electric fence net 4, and a protective layer laid on the ground surface 7 The lowermost conductive band 3 is laid on the grass sheet 9, and the remaining part of the electric fence net 4 is vertically stretched by the support column 1 on the center line in the length direction of the grass protection sheet 9. Then, odd-numbered conductive bands 3 counted from the bottom are connected to the negative side of the impact high-voltage power supply 5, and even-numbered conductive bands 3 counted from the bottom are connected to the positive side of the impact high-voltage power supply 5.

In this way, when a harmful animal such as the moth 6 approaches the stretched net 4 when trying to enter the field, it always stands on the conductive band 3 at the bottom of the net 4 of the electric fence. If a pest such as 6 touches the second conductive band 3 from the bottom, an electric shock is received.

As shown in FIG. 4, the conductive band 3 at the bottom of the electric fence net 4 of the present invention is laid on the weedproof sheet 9 laid on the ground surface 7, and the remaining part of the electric fence net 4 is covered with the weedproof sheet 9. If it is stretched vertically by the support column 1 on the longitudinal center line, it is possible to reliably cause an electric shock to a pest 6 or other harmful animal, and the grass growth sheet is inhibited by the weed control sheet 9, so Labor can be greatly reduced.

The width of the electric fence net 4 is 2.5 m, the width of the lowermost conductive band 3 is 0.6 m, and the width of the grass protection sheet 9 is 1 m. It is desirable that the mesh of the lowermost conductive band 3 be 5 cm or less so that a harmful animal such as a kite 6 always steps.
