Description

The present invention relates to an electric fence device that delivers an electric shock to various wild animals.

Electric fences, which are used to manage livestock grazing and prevent wild animals from entering the area, have been known for a long time.
Known types of conventional overhead wire-type electric fences include a type that has posts erected at specified intervals, multiple bare electric wires stretched in multiple stages between adjacent posts, and a power supply unit that supplies power to the bare electric wires (Patent Document 1), and a type that has a net provided between adjacent posts with multiple bare electric wires stretched on top of the net (Patent Documents 2 and 3).
Both types are designed to deliver an electric shock to wild animals the moment they come into contact with bare electric wires.

JP 2003-299433 A (FIG. 7) Japanese Patent Application Laid-Open No. 06-225680 Japanese Patent Application Laid-Open No. 08-112055

Conventional overhead wire type electric fences have the following inherent problems that need to be solved:
<1> The bare electric wire is strung continuously around the entire circumference of the fence body.
Therefore, if an electrical fault such as a leakage current or a short circuit occurs in part of the bare electric wire, the impact of the electrical fault will extend to the entire length of the bare electric wire, significantly reducing its functionality as an electric fence or causing it to completely lose its functionality.
<2> As in Patent Document 2, etc., bare electric wires are wired continuously around the entire circumference of the fence, and if an electrical fault occurs in part of the bare electric wires, the manager needs to patrol the entire circumference of the fence to check and identify the location of the electrical fault.
The total length of the fence can reach several thousand meters, so it takes a lot of time and effort to identify the location of the electrical disturbance.
<3> To keep an electric fence in good working order, it is necessary to patrol the entire perimeter of the fence and to cut back more vegetation than necessary, which requires a lot of effort, time, and cost to maintain the electric fence.

The present invention aims to provide an electric fence device that can solve the problems mentioned above.

The present invention provides an electric fence device for wild animals comprising a fence body including at least a plurality of posts erected at intervals, and a power supply system that is wired so as to supply power individually to each of a plurality of divided sections obtained by dividing the fence body along the longitudinal direction of the fence body, the power supply system at least comprising a single power supply device that generates high voltage pulses, a main line with an insulating coating structure that is connected to the output line of the power supply device and wired continuously throughout all of the divided sections of the fence body, a plurality of branch wires with an insulating coating structure branching off from the main line so as to correspond individually to the plurality of divided sections, a resistor interposed in part of the branch wire, and split bare electric wires connected to each of the branch wires so as to supply power individually to the plurality of divided sections, and is configured by wiring through the main line so as to supply power individually to each of the split bare electric wires that are separated into a plurality of divided sections and hung horizontally.
In another form of the present invention, the power supply system may further include a voltage sensor that measures the voltage of the divided bare electric wires provided in each divided section, and a communications module that transmits the measurement data of the voltage sensor to an administrator, and be configured to be able to transmit the measurement data of the voltage of each of the divided bare electric wires provided in the multiple divided sections to the administrator.
In another embodiment of the present invention, a single resistor may be provided for each of the divided sections, and wiring may be performed so that power can be supplied to a plurality of divided bare electric wires that are horizontally arranged in parallel across each of the divided sections through the single resistor.
In another embodiment of the present invention, a plurality of resistors may be provided for each of the divided sections, and wiring may be provided so as to supply power to a plurality of divided bare electric wires that are arranged in parallel across each of the divided sections through the plurality of resistors.
In another embodiment of the present invention, the divided section is defined by a pair of boundary posts erected at a distance from each other, and both ends of the divided bare electric wire are fixed to the pair of boundary posts and laid horizontally.
In another embodiment of the present invention, the start and end of the divided bare electric wires extending across adjacent divided sections may be insulated and fixed to a common boundary post.
In another embodiment of the present invention, the divided section may have an intermediate support erected between a pair of boundary supports, and both ends of the divided bare electric wire may be supported by the intermediate support.
In another embodiment of the present invention, the fence body may have the plurality of divided bare electric wires arranged in multiple stages in the same divided section of the fence body.
In another form of the present invention, the fence body may be provided with an animal-proof netting horizontally disposed between adjacent posts, and divided bare electric wires may be horizontally disposed above or to the sides of the animal-proof netting in multiple divided sections.

<1> By dividing the divided bare electric wire into several divided sections through the main line and wiring each divided bare electric wire so that it can supply power individually through an interposed resistor, it is possible to generate a unique voltage for each divided section.
Therefore, it is possible to reduce the maintenance of the split bare electric wires while providing an animal prevention function.
<2> The main line cable laid over the entire length of the fence body has an insulated coating structure, so voltage drops caused by leakage current through the main line can be avoided.
<3> Even if an electrical fault such as a leakage current or short circuit occurs in the electric fence wire of a specific divided section, the impact of the electrical fault in the specific divided section will not extend to other divided sections.
Therefore, the divided sections other than the section in which the electrical disturbance occurred can maintain normal voltage, and the electric fence does not lose its function.
<4> The administrator can identify electrical disturbances, etc. in specific sections based on the changes in voltage in each section, so that electrical disturbances, etc. can be discovered in a short period of time and responded to promptly.
<5> By placing a metal animal-proof net connected to the negative terminal of a power supply directly below the split bare electric wires so that a sudden voltage drop occurs when a wild animal or other animal tries to climb over the electric fence, each split bare electric wire can function as an animal intrusion detection sensor.
<6> By adding a voltage sensor and a communication module to the power supply system, it will be possible to more accurately detect the intrusion of wild animals from a specific section, and it will be possible to quickly detect the intrusion of dangerous animals such as bears into urban areas.

[Example 1]
<1> Overview of the electric fence device The following description will be given with reference to Figures 1 to 3.
The electric fence device of the present invention comprises a fence body 10 which includes at least a number of posts 11 erected along an animal-prevention area, and a power supply system 20 which divides the fence body 10 into a number of separate sections 10a, 10b, ... along the longitudinal direction of the fence body 10 and is wired so that power can be supplied individually to these multiple separate sections 10a, 10b, ....

<2> Fence Body The fence body 10 comprises a plurality of posts 11 arranged upright at a predetermined interval.
In this example, a form will be described in which the fence body 10 is configured by arranging a plurality of divided bare electric wires 24 horizontally in multiple stages between a plurality of supports 11 erected in each divided section 10a, 10b, . . . .

<2.1> Supports The intervals at which the supports 11 are installed are appropriately selected depending on the type of wild animal.
The posts 11 are preferably made of a non-conductive material (resin, wood, bamboo, etc.), but may also be made of a conductive material (metallic pipes or bars).

<2.2> Divided Sections In the present invention, the fence body 10 is divided at any distance along the longitudinal direction of the fence to form a plurality of divided sections 10a, 10b, ....
The reason for forming the plurality of divided sections 10a, 10b, . . . is to supply power to each divided section individually without being affected by the other divided sections.

The distance of each of the divided sections 10a, 10b, . . . is selected appropriately taking into consideration the cost of materials and the time required to discover an electrical fault or the like when it occurs.
A suitable length of one divided section is, for example, 50 to 150 m.
If one divided section is shorter than 20 m, there is a problem in that the material costs of the electric fence device increase.
If one divided section exceeds 150 m, while the material costs of the electric fence device will be reduced, there will be a problem that it will take a long time to find the location of any electrical faults such as leakage current or short circuits.

<2.2.1> Relationship between divided sections and pillars As shown in FIG. 1, each divided section 10a, 10b, . . . is defined by a plurality of pillars 11 (a pair of boundary pillars 11a).
For example, taking the divided section 10a as an example, a pair of boundary supports 11a, 11a are located at the beginning and end of the section 10a, and one or more intermediate supports 11b are located therebetween.

<2.2.2> Boundary Supports The boundary supports 11a, 11a in the present invention are supports for fixing the start and end points of the divided bare electric wires 24 in each of the divided sections 10a, 10b, . . .

To prevent the start and end points of each split bare electric wire 24 from being too far apart, it is advisable to share a boundary support 11a at the boundary between each split section 10a, 10b, ... and fix the start and end points of each adjacent split bare electric wire 24 to a part of the shared boundary support 11a.

<2.2.3> Intermediate Support The intermediate support 11b is a support provided between the boundary supports 11a, 11a in each of the divided sections 10a, 10b, 10c, ..., and functions to support the divided bare electric wires 24 and prevent them from sagging.

<3> Power supply system The power supply system 20 comprises a power supply unit 30, a main line 21 electrically connected to the power supply unit 30 and wired along the entire length of the divided sections 10a, 10b, ... of the fence body 10, a plurality of branch lines 22 branching off from the main line 21 to correspond to each of the divided sections 10a, 10b, ..., a resistor 23 interposed in each branch line 22, and one or more divided bare electric wires 24 connected to each branch line 22.

The power supply system 20 comprises at least a single power supply unit 30 that generates high-voltage pulses, a main line 21 with an insulating coating structure that is connected to the output line of the power supply unit 30 and is continuously wired across all the divided sections 10a, 10b, ... of the fence body 10, and divided bare electric wires 24 that are provided separately from the main line 21 so as to be able to individually correspond to the multiple divided sections 10a, 10b, ..., and the main line 21 is wired so that each divided bare electric wire 24 that is cut into multiple divided sections 10a, 10b, ... and laid horizontally can supply power individually.

<3.1> Power supply unit The power supply unit 30 is a device that generates a constant-period high-voltage pulse (3,500 to 7,500 V) based on a power source such as a dry cell, a solar cell (solar type), a battery (12 V), or a household power source (100 V), and supplies power to each of the divided bare electric wires 24.
In this embodiment, a configuration will be described in which the positive pole of the output line of the power supply device 30 is connected to the main line 21, while the negative pole is grounded to the ground.
In the present invention, the entire length of the fence body 10 is divided into multiple sections (divided sections 10a, 10b, 10c, ...), and power is supplied to each of the divided sections 10a, 10b, 10c, ... through one power supply unit 30 and one main line 21.

<3.2> Main Line The main line 21 is a conductive wire that is continuously wired over the entire length of the fence body 10 (all divided sections 10a, 10b, ...) and is covered with insulating material over its entire length to prevent electric leakage.
The main line 21 may be buried underground, laid on the ground surface, or laid along part of the fence body 10.

The main line 21 should be made of neon tube cable (voltage resistance 15 kV) with low electrical resistance to prevent voltage drop due to the resistance of the cable itself, and it is desirable to protect the main line 21 with a plastic pipe or similar to prevent it from being chewed through by rats or other animals.

<3.3> Branch Wire The main line 21 is not directly wired to the divided bare electric wires 24, but is connected to the divided bare electric wires 24 provided in each divided section 10a, 10b, ... via a branch wire 22.
The branch wires 22 are conductive wires branched off from the main wire 21 so as to correspond individually to each of the divided sections 10a, 10b, . . . , and electrically connect the main wire 21 to each of the divided bare electric wires 24.
The branch line 22, like the main line 21, is covered with an insulating material over its entire length.
The branch line 22 is provided in order to interpose a resistor 23 between the main line 21 and the bare electric wire division 24 .

Like the main line 21, the branch line 22 also uses a neon tube cable (withstand voltage 15 kV) with low electrical resistance, and is further protected by a poly pipe or the like.
The branch point of the main line 21 and the branch line 22 has to be exposed from the poly pipe, but is protected using PVC pipe joints.
Furthermore, the main line 21, which is laid over the entire length of the fence body, and the multiple branch lines 22 branching off from the main line 21 are made of insulating cables, so there is no risk of electric leakage from the main line 21 or the branch lines 22.

<3.4> Resistor A resistor 23 is interposed in each branch line 22.
The resistor 23 is an electrical resistor for limiting the load on the main line 21 when an electrical fault such as a leakage current occurs in any of the divided sections 10a, 10b, ..., so as to prevent a voltage drop from affecting the other divided sections.

In this example, a resistor 23 is provided for each divided section 10a, 10b, ..., and multiple divided bare wires 24 are arranged in parallel to one resistor 23.

<3.5> Split bare electric wires The split bare electric wires 24 connected to the ends of the branch wires 22 are conductive wires for conducting electricity between the split sections 10a, 10b, ..., and the split bare electric wires 24 are exposed over their entire length.

<3.5.1> Arrangement of the divided bare electric wire In the present invention, unlike conventional electric fences, a continuous bare electric wire is not wired around the entire circumference of the fence body, but the divided bare electric wires 24 are separated and wired independently for each of the divided sections 10a, 10b, ....
In other words, the divided bare electric wires 24 have a start point and an end point for each divided section 10a, 10b, ..., and the start point and the end point of each divided bare electric wire 24 are fixed to a common boundary post 11a.
In each of the divided sections 10a, 10b, ..., the multiple divided bare electric wires 24 are arranged in a vertical line, so that the multiple divided bare electric wires 24 appear as if they have continuity, but in reality, they are separated and independent in each of the divided sections 10a, 10b, ....

<3.5.1.1> When the boundary post is made of a conductive material When the boundary post 11a is made of a conductive material such as a steel pipe, the ends of the split bare electric wires 24 are fixed via a non-conductive insulator 13.
As the insulator 13, a known insulator, a wire clip, or the like is used.

<3.5.1.2> When the intermediate support is made of a conductive material When the intermediate support 11b is made of a conductive material, the intersection with the split bare electric wire 24 is supported via a non-conductive insulator 13.

<3.5.2> Number of Wires in the Split Electric Wires Although FIGS. 1 and 2 show a configuration in which three split bare electric wires 24 are wired in parallel in each of the split sections 10a, 10b, ..., the number of wires in the split bare electric wire 24 may be one or more.

<3.5.3> Wiring Spacing of Split Electric Wires When wiring multiple split bare electric wires 24 in parallel, the wiring spacing is appropriately selected depending on the size of the target wild animal, etc.

<3.6> Other Equipment If necessary, the power supply system 20 may further include a voltage sensor 26 and a communication module 27 for each of the divided bare electric wires 24 provided in each of the divided sections 10a, 10b, . . .
The voltage sensor 26 is electrically connected to the split bare electric wire 24 and constantly measures the voltage of the split bare electric wire 24 .
The communication module 27 operates in conjunction with the voltage measurement sensor 26 and may constantly transmit voltage measurement data of each divided bare wire 24 to the administrator wirelessly or via cable, or may be configured to transmit voltage drop information of a specific divided section to the administrator when a voltage drop is detected by the voltage measurement sensor 26.
The communication module 27 may be, for example, a known e-mail system.

[Electric fence device operation]
The operation of the electric fence device will be described with reference to Figures 3A and 3B.

<1> Normal Operation Figure 3A shows a model diagram of an electric fence device under normal operation.
In the figure, for ease of understanding, the split bare electric wires 24 arranged in each of the divided sections 10a, 10b, . . . are shown as single wires, and the intermediate supports 11b in each of the divided sections 10a, 10b, .

The power supply unit 30 supplies power via a main line 21 and a branch line 22 to divided bare electric wires 24 that are installed separately and independently in each divided section 10a, 10b, . . .
Under normal conditions when there is no contact with wild animals or no electrical leakage across any of the divided sections 10a, 10b, . . . , an electrical pulse is supplied from the power supply device 30 through the main line 21 and the branch line 22 to each of the divided sections 10a, 10b, .

In a normal state, the voltage sensor 26 measures a specific voltage for each of the divided sections 10a, 10b, . . .
Voltage information for each section measured by the voltage sensor 26 is periodically transmitted via the communication module 27 to the receiving module of the administrator.

<2> When a wild animal invades FIG. 3B shows a model diagram of an electric fence device when a wild animal is attempting to invade part of the divided sections 10a, 10b, ....

<2.1> Administration of electric shock If a wild animal attempts to enter a prohibited area such as a field or orchard and comes into contact with, for example, the split bare electric wire 24 wired in one of the divided sections 10c, electricity will flow between the ground and the split bare electric wire 24, and the wild animal will be given a strong electric shock.
If a wild animal repeatedly comes into contact with the split bare wires 24, an electric shock will be administered each time.
The painful learning effect discourages wild animals from entering the restricted area, effectively eliminating them.

<2.2> Effects on other divided sections When a wild animal comes into contact with the divided bare electric wire 24 wired in a particular divided section 10c, the voltage in the divided section 10c changes temporarily and significantly.
Since the resistors 23 are provided in all of the divided sections 10a, 10b, . . . , even if a voltage change occurs in a specific divided section 10c, this voltage change does not affect the other divided sections 10a, 10b, 10d, .
Therefore, even if wild animals simultaneously invade multiple divided sections 10a, 10b, ..., the intrusion of wild animals can be effectively suppressed.

<2.3> Checking for Intrusion of Wild Animals When a wild animal receives an electric shock in one of the divided sections 10c, the voltage in that divided section 10c changes temporarily and significantly.

When an electric shock is administered to an invading wild animal, the voltage in a specific divided section 10c changes, and this voltage change is notified to the administrator via the voltage sensor 26 and the communication module 27.

Based on the voltage information of all divided sections 10a, 10b, ... transmitted through the voltage sensor 26 and the communication module 27, the manager can instantly confirm the intrusion of a wild animal and grasp the location (specific divided section 10c) from which the wild animal attempted to intrude.
If the wild animal is an aggressive animal such as a bear, it is possible to go directly to a specific divided section 10c to exterminate the wild animal or set a trap to capture it, if necessary.

<3> In the event of an electric leakage Figure 3B also serves as a model diagram of an electric fence device in the event of an electric leakage.

Conventional electric fences, which typically have a continuous bare wire connected to a single power supply, generally show the same voltage no matter where you measure it on the fence.
Therefore, with conventional long-distance electric fences, if a leakage current occurs somewhere, not only does it take a long time to find the leak, but the voltage drops over the entire length of the bare wire, reducing the functionality of the electric fence or causing it to lose all functionality.

<3.1> Scope of influence of leakage current In contrast, in the present invention, a resistor 23 is provided in each of the divided sections 10a, 10b, 10c, ..., so that even if a leakage current occurs in a specific divided section 10c due to contact with herbaceous plants, etc., the influence of the leakage current will not extend to the other divided sections 10a, 10b, 10d, ....
In other words, the effect of the electric leakage is limited to the specific divided section 10c in which the electric leakage has occurred, and the other divided sections 10a, 10b, 10d, . . . can maintain a normal power supply state (normal voltage).
Therefore, the electric fence can continue to function in all divided sections except for the divided section 10c where the leakage current has occurred.

<3.2> Location of leakage current When a leakage current occurs in one of the divided sections 10c, the voltage sensor 26 detects a voltage drop in that section 10c and notifies the administrator of the leakage current in the specific divided section 10c via the communication module 27.
This enables the administrator to grasp the occurrence of a leak and the location where the leak occurred (a specific divided section 10c).

<3.3> Confirmation and recovery from leakage current In the present invention, by inserting a resistor 23 into part of the branch line 22 and further wiring a split bare electric wire 24 to the end of the resistor 23, it is possible to create a situation in which a unique voltage is measured for each divided section 10a, 10b, ... (for each branch line 22), despite the use of a single power supply unit 30.
Since the manager can specify the approximate location where the leakage current has occurred (the specific divided section 10c), there is no need to check sections that do not have leakage current as well.
Therefore, the location of the electric leakage in a specific divided section 10c can be found within a short period of time.

The manager eliminates the cause of the leakage current and restores the specific divided section 10c.
If the cause of the leakage current is contact with herbaceous plants, the specific divided section 10c can be restored quickly by cutting the herbaceous plants.

In the present invention, leakage current management is performed by utilizing the fact that each of the divided sections 10a, 10b, . . . exhibits a unique voltage.
This eliminates the need to patrol the entire perimeter of the fence or to cut back vegetation more than necessary in order to maintain its functionality as an electric fence, significantly reducing the effort, time and cost required to maintain the electric fence device.

<4> In the event of a short circuit When a short circuit occurs in the divided bare electric wires 24 of some of the divided sections 10a, 10b, ..., the operation is the same as that in the event of an electric leakage as described above.

For example, even if a short circuit occurs in the divided bare electric wire 24 of one of the divided sections 10c and the voltage drops to approximately 0 V, the effect of the short circuit is contained only in the specific divided section 10c, and the effect of the short circuit does not extend to the other divided sections 10a, 10b, 10d, ....
Therefore, all divided sections except for the specific divided section 10c where the short circuit occurred can continue to function as an electric fence.

The occurrence of a short circuit in a specific divided section 10c and the location of the short circuit (specific divided section 10c) are notified to a receiving module (not shown) of the administrator via the voltage sensor 26 and the communication module 27.
If necessary, the manager will go directly to the location where the short circuit has occurred to confirm the short circuit.
If the cause of the short circuit is an electrical short circuit, the cause of the short circuit is eliminated and the specific divided section 10c is restored.

[Example 2]
Other embodiments will be described below. In the description, the same parts as those in the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

<1> Structure of the Split Bare Electric Wire In the above-described first embodiment, the adjacent split bare electric wires 24, 24 are separated using an insulating material 13 such as a porcelain insulator. However, the structure of the separation of the adjacent split bare electric wires 24 is not limited to the structure in the first embodiment.

FIG. 4A shows a configuration in which adjacent split bare electric wires 24 are separated using a metal wire fitting 14 such as a clip.
In this example, metal wire fittings 14, 14 such as clips are attached to both sides of the boundary support 11a, and the start and end points of adjacent divided bare electric wires 24, 24 are fixed to each wire fitting 14, 14.
In this example, a separator 15 made of an insulating material is interposed between the two wire fittings 14, 14, thereby separating the adjacent split bare electric wires 24, 24 while sharing the boundary support 11a.

FIG. 4(b) shows a configuration in which adjacent split bare electric wires 24 are separated without sharing a boundary post 11a.
In this example, a pair of boundary posts 11a are used independently for each of the divided sections 10a, 10b, . . . to separate adjacent divided bare electric wires 24, 24.
In this example, two boundary posts 11a are erected next to each other, and the start and end points of adjacent split bare electric wires 24, 24 are fixed via metal overhead line fixtures 14 or the like provided on each boundary post 11a, thereby separating the adjacent split bare electric wires 24, 24.

<2> Effects of this Example This example has the same effects as those of the first embodiment described above.
In particular, in this example, the dividing structure of the split bare electric wire 24 can be changed depending on the installation environment and site of the electric fence device.

[Example 3]
Referring to FIG. 5, another arrangement of the resistor 23 will be described assuming that a plurality of divided bare electric wires 24 are arranged in parallel in multiple stages in the same divided section.

<1> Other Arrangements of the Resistor In this embodiment, the branch line 21 is branched into a plurality of branches, and the resistors 23 are individually arranged between the branch line 21 and each of the divided bare electric wires 24 .
That is, the same number of resistors 23 as the number of wires of each divided bare electric wire 24 are used.

<2> Effects of this Example This example has the same effects as those of the first embodiment described above.
In particular, in this example, by disposing resistors 23 individually for each of the multiple divided bare electric wires 24, even if a wild animal comes into contact with one of the divided bare electric wires 24 or a ground fault occurs, the impact will not extend to the other divided bare electric wires 24 in the same divided section.

[Example 4]
Another electric fence device will now be described with reference to FIG.
<1> Other electric fence devices The electric fence device of this example differs from Example 1 in that the fence body 10 is composed of a number of posts 11 (boundary posts 11a, intermediate posts 11b) and an animal-proof net 12 stretched continuously between each of the posts 11.
Since this embodiment also includes the power supply system 20 as in the first embodiment, a detailed description of the power supply system 20 will be omitted.

In this example, an animal-proof net 12 is laid horizontally between adjacent posts 11, and one or more split bare electric wires 24 are installed on the top of the posts 11 protruding from the upper edge of the animal-proof net 12.
In this example, it is sufficient that one or more split bare electric wires 24 are positioned above the animal-proof net 12 .

<2> Animal prevention net An animal prevention net 12 is attached between adjacent posts 11.
The animal prevention net 12 is a high-strength mesh-structured net material that prevents the intrusion of wild animals, and may be made of, for example, conductive wire mesh or non-conductive net material.
The overall dimensions of the animal protection net 12 are appropriately selected depending on the type of wild animal.

If the animal protection net 12 is made of a conductive material, the negative terminal extending from the power supply unit 30 and grounded to the earth is also connected to a part of the animal protection net 12.

<3> Operation of the electric fence device In this example, the animal prevention net 12 stretched horizontally between adjacent posts 11 physically prevents the intrusion of wild animals.
When wild animals such as bears and monkeys try to climb over the animal-prevention net 12, they come into an energized state when they touch the split bare electric wires 24, causing an impulse current to flow through the wild animal's body, resulting in an electric shock.
The painful learning effect of electric shocks can effectively prevent wild animals from entering restricted areas.

<4> Effects of this Example In addition to achieving the same effects as those of the first example described above, this example makes it possible to quickly detect and take necessary measures against the increasing number of cases in which bears, which pose a risk of causing personal injury, have invaded areas where people live in recent years.

[Example 5]
Another electric fence device will now be described with reference to FIG.
<1> Other electric fence devices This example is a modification of the fourth embodiment, and describes a configuration in which a single or multiple divided bare electric wires 24 are horizontally hung on the side of the animal prevention net 12 for each of multiple divided sections.
Since this embodiment also includes the power supply system 20 as in the first embodiment, a detailed description of the power supply system 20 will be omitted.

<2> Arrangement structure of split bare electric wire To suspend the split bare electric wire 24 across adjacent pillars 11, for example, the split bare electric wire 24 is suspended across an outrigger 16 protruding from a part of each pillar 11 (boundary pillar 11a, intermediate pillar 11b) and an insulator 13 such as a porcelain insulator attached to the outrigger 16.

If the support 11 is made of a conductive material, an insulator 13 is provided, and if the support 11 is made of an insulating material, the insulator 13 may be omitted.

The outrigger 16 may be provided as a part of the animal prevention net 12.
In addition, the animal prevention net 12 may be installed in the same position relative to each support 11 as the side on which the outriggers 16 are installed.

<3> Operation of the electric fence device If the animal-proof net 12 is made of a conductive material, the negative pole extending from the power supply unit 30 and grounded to the ground is connected to a part of the animal-proof net 12 .
In this example, when a wild animal such as a bear or monkey tries to climb over the animal-proof net 12, it becomes electrically conductive when it touches the split bare electric wires 24, causing an impulse current to flow through the wild animal's body, resulting in an electric shock.
