Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric fence, and more particularly to an electric fence that can prevent animals from coming and going between a protected area and an unprotected area and can be constructed at low cost.
[0002]
[Prior art]
Recently, to protect field crops from livestock and wildlife, or to prevent livestock from being separated from the ranch, electricity has been added to the boundary between protected fields such as fields and ranches and their surrounding unprotected areas. Construction of fence is carried out.
[0003]
The electric fence is constructed by setting up a pile along the boundary between the protected area and the non-protected area, and holding the bare wire, which is a conductive member routed along the boundary. Apply voltage. When livestock or wild animals come into contact with bare electric wires of an electric fence, a high-voltage current applied by the power supply device flows through the body to the ground and receives an electric shock. As a result, the electric fence prevents animals from moving back and forth between the protected area and the unprotected area.
[0004]
[Problems to be solved by the invention]
By the way, the conventional electric fence uses an insulator in order to hold a bare electric wire on the pile erected along the boundary between the protected area and the non-protected area.
[0005]
However, insulators have a high unit price and are easily damaged. Further, in order to fix the insulator to the pile, there is a problem that it is necessary to form a bolt insertion hole in the pile and to use a dedicated fixing tool such as a hook bolt. For this reason, the electric fence which made the pile hold | maintain a bare electric wire using a lever has the problem which raises a cost.
[0006]
A power supply device that applies a high voltage to a bare wire is composed of a battery as a power source, an oscillator for generating a high voltage, a transformer, and the like, but is installed outdoors in fields such as fields and ranches. It is necessary to provide a water-resistant outer shell that can be protected from wetness due to rain or the like. For this reason, the power supply device has the disadvantage of increasing the size and complexity of the structure.
[0007]
[Means for Solving the Problems]
Therefore, in order to eliminate the inconvenience described above, the present invention provides a plastic bottle fixedly provided on a pile standing along the boundary between the protected area and the non-protected area, and the plastic bottle is routed along the boundary. The bare wire or the insulated thin film coated wire is held and provided, and a power supply device for applying a high voltage to the bare wire or the insulated thin film coated wire is disposed in the PET bottle.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The electric fence according to the present invention is provided with a plastic bottle fixed to a pile standing along a boundary between a protected area and a non-protected area, and a bare electric wire or an insulating thin film coated electric wire arranged along the boundary in the PET bottle. Can be used to route bare wires or insulated thin-film coated wires without the need for insulators or insulator-dedicated fixtures, and high voltage can be applied to bare wires or insulated thin-film coated wires. By disposing the power supply device to be applied in the PET bottle, the power supply device can be easily made into a water-resistant structure, and the outer shell of the water-resistant structure can be made unnecessary.
