Description

In order to prevent damage to crops and the like by a large variety of wild animals from large beasts such as wild boars and deer to small beasts such as raccoon dogs and raccoons, the present invention It relates to an entry prevention fence.

In recent years, the damage to agriculture and forestry by wild animals has been getting worse. Therefore, as a countermeasure, installation of an entrance prevention fence is widely performed. As an intrusion prevention fence, the invasion of the target animal is blocked by a physical barrier using a net or the like (Patent Document 1), or by an electric shock caused by a bare electric wire connected to the power supply device. What is to be prevented (Patent Document 2) is common. In addition, fences are also used that are designed to prevent psychological invasion against wild animals with strong vigilance by installing blindfolds such as tin plates so that the inside of the fence is not visible from the outside.

In addition, the target wild animals are various, such as monkeys, deer, wild boars, raccoon dogs, and raccoons. In most cases, multiple species are simultaneously problematic. Therefore, the intrusion prevention fence is required to cope with the body size and exercise ability of various wild animals.

However, in the physical barrier fence described above, it is necessary to completely cover the ceiling portion of the field in order to prevent the invasion of animals such as monkeys having excellent climbing ability, which requires a lot of labor and cost for installation and maintenance. In addition, in an electric shock fence, it is necessary to stretch a bare wire at a multi-stage height in order to cope with animals of various body sizes. Furthermore, in order to prevent small animals from slipping through, it is necessary to lay bare wires at a height close to the ground, but frequent weeding work is essential to prevent weeds from touching and leaking electricity. It takes a lot of labor for maintenance. In addition, the blindfold material fence becomes more easily affected by the wind as the fence height increases, and the possibility of collapse during a strong wind becomes very high. Therefore, it is difficult to deal with animals with high eyes such as deer.

Thus, a great deal of labor and cost are required to install and maintain an intrusion prevention fence corresponding to various animals. However, the damage caused by wild animals is mainly in hilly and mountainous areas. In these areas, the terrain is steep and the population is aging so much that it is very difficult to secure the necessary labor. In addition, the cultivated area is small compared to the flat land and the profitability is poor, so the cost that can be input is limited. As described above, it is difficult to prevent damage efficiently with the conventional technology.

As described above, the conventional technique has a problem that it is very difficult in terms of effect and labor to install an intrusion prevention fence that can cope with various wild animals. An object of the present invention is to realize an intrusion prevention fence that can be installed and maintained in a labor-saving manner and that is highly effective against multiple beast species.

According to the present invention, the fence means in which the material is stretched on the support is a double fence installed on the outside and inside at a predetermined interval, and the outside fence means is a material that physically hinders the behavior of wild animals. A wild animal intrusion prevention fence is provided, characterized in that a shading net that obstructs the vision of wild animals is stretched on the inner fence means.

Further, the present invention is a double fence in which the fence means in which materials are stretched on the pillar are installed on the outside and the inside at a predetermined interval, the pillar of the outer fence means is inward and the pillar of the inner fence means is outward. A wild animal intrusion prevention fence characterized by having an inverted V-shaped structure in which each column is inclined and connected to each other at the top is provided.

The present invention also provides a wild animal intrusion prevention fence characterized in that the support column of the fence means is made of a conductive material.

Moreover, this invention provides the wild animal invasion prevention fence characterized by installing the conductive weed control sheet | seat in the ground surface part.

According to the present invention, because of the visual obstruction material stretched on the inner fence means, wild animals with strong vigilance regardless of the type are not confirmed to be safe in the fence, so that the invasion behavior becomes passive. Therefore, the effect of the physical action inhibiting material stretched on the outer fence means is maximized. Moreover, since the visual inhibition material avoids the approach of the target animal to the closest distance by the physical behavior inhibition material, the maximum effect is exhibited. That is, a greater invasion inhibitory effect can be obtained for many animal species by a synergistic effect obtained by combining behavioral inhibition and visual inhibition. As a result, the physical intrusion prevention material can be used only with simple materials that are excellent in installation workability and maintainability, such as bare wires and nets connected to a power supply device to which an impact voltage is applied, and low cost. . Furthermore, it is possible to apply a light-shielding net that has strong wind resistance but can be seen through at close range as a visual hindrance material, and can avoid situations where the fence collapses or deforms during strong winds. .

In addition, since the struts have a palm structure, it is possible to realize a strong fence strength with a simple structure. As a result, the installation workability and maintainability can be improved, and strength sufficient for large beasts such as deer and wild boar can be maintained. Moreover, although it is a double fence, since it becomes unnecessary to provide an individual support structure for each fence means, the depth of a fence becomes small and the sacrifice of the cultivation area by installation of a fence can be suppressed to the minimum.

Furthermore, when using a bare wire connected to a power supply device as a physical intrusion prevention material, not only when the target animal comes into contact with the ground and the bare wire by using a conductive material such as an iron pipe for the support of the fence Also, when a part of the support comes into contact with the bare wire, an impact voltage is felt. As a result, it is possible to increase the chance of electric shock of the target animal, and even small animals whose legs are separated from the ground when coming into contact with the bare electric wire can be electrocuted. High invasion inhibitory effect can be obtained.

In addition, by installing a conductive weeding sheet on the ground surface, it is possible to prevent leakage due to the contact of the overgrown weeds with the bare wire without impairing the effect of the impact voltage. This eliminates the need for frequent mowing work with a large labor burden, and can significantly improve the maintenance of the fence.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings, but the invention is not limited thereto.

FIG. 1 is an external perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view. The wild animal intrusion prevention fence according to the present invention basically has a configuration in which an outer fence means 10 having a physical invasion inhibiting effect and an inner fence means 20 having a visual blocking effect are connected to an inverted V-shaped structure by a horizontal pipe 30. It has. Since wild animals that have attempted intrusion cannot confirm the safety inside the fence by the inner fence means 20, the intrusion behavior becomes negative, and the physical invasion deterrent effect by the outer fence means 10 is maximized. Moreover, since the target animal cannot approach the closest distance of the inner fence means 20 by the outer fence means 10, the visual obstruction effect of the inner fence means 20 is exhibited to the maximum extent.

The outer fence means 10 is provided with a behavior inhibition net 11 that is a material that physically inhibits behavior. The behavior inhibition net 11 is made of polyethylene or the like, and has a strength that can not be cut even when a large beast such as a wild boar tries to enter. Moreover, by installing in a slightly slackened state, the foot of the target animal is entangled with the behavior inhibition net 11 and the invasion inhibition effect is enhanced.

Two steps of insulators 41 are attached to the outer fence means support column 12, and a lower bare wire 42 and a middle bare wire 43 connected to the positive pole of the power supply device that generates an impact current pulse are stretched. Further, a folding pole 50 is installed on the outer fence means support column 12, and an upper-stage bare electric wire 44 connected to the power supply device is similarly stretched there. Note that the negative pole of the power supply device is grounded to the ground 70. The outer fence means column 12 and the horizontal pipe 30 use conductive materials such as a straight metal pipe, and the outer fence means column 12 is driven into the ground. An impact current can be applied to the target animal not only when it contacts the ground simultaneously but also when it contacts the outer fence means column 12 at the same time. Therefore, even in the case of wild animals such as the wild boar that only energizes only a part of the body such as the nose and the raccoon dog that leaves its foot away from the ground when it comes into contact with the bare electric wire, the invasion inhibiting effect by the impact current is enhanced. Further, when an animal having excellent climbing ability such as a monkey tries to invade, the target animal is attached to the folded pole 50 projecting outward with an unstable posture, and the stretched bare electric wire 44 and the outer fence means Intrusion is inhibited together with the impact current when the strut 12 or the horizontal pipe 30 is simultaneously contacted. In addition, the number of installation stages of the bare electric wire and the insulator may be any number, and is adjusted according to the type of the target animal and the frequency of appearance at the fence installation location.

A light shielding net 21 is stretched on the inner fence means 20. The light-shielding net 21 is a net material in which dark colored yarns are knitted with high density and blocks most of the light. In addition, since a certain level of ventilation is ensured, the wind resistance of the fence is greatly improved as compared with the case of using a material that does not transmit light and does not transmit air, such as a tin plate. Further, the light shielding net 21 has a drawback that the other side can be seen through a little at a close distance. However, the outer fence means 10 prevents the target animal from approaching the close distance, thereby covering this drawback.

The outer fence means column 12 and the inner fence means column 22 are connected with an inverted V-shaped structure. By adopting this structure, the outer fence means 10 and the inner fence means 20 support each other, and the fence strength that can cope with large beasts such as deer and wild boar is realized. In addition, since the structure is simple, installation workability and maintainability are ensured.

A conductive weed sheet 60 is laid on the ground surface. Since the conductive weed sheet 60 functions to suppress the growth of weeds by blocking light, a situation in which weeds come into contact with the bare electric wires 42, 43 or 44 can be saved labor-saving. In addition, the conductive weeding sheet 60 is made of a conductive material such as a conductive plastic, or a method of opening a large number of small holes in the sheet so as not to hinder the weeding function. The sex is secured. Therefore, even when the target animal is in contact with the bare electric wires 42, 43, or 44 while being on the conductive grass sheet 60, the intrusion behavior is inhibited by the impact current.

It is an external appearance perspective view which shows one Embodiment of this invention. It is sectional drawing which shows one Embodiment of this invention.
