Hereinafter, a snake climbing prevention device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an external view showing a state where a snake climbing prevention device according to an embodiment of the present invention is installed on a utility pole, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. It is a perspective view which shows a member.

As shown in FIGS. 1 to 2, the snake climbing prevention device 1 according to the present embodiment is installed on a utility pole 2.

And have.

  As shown in FIG. 3, the outer circumferential member 3 is formed of an insulating material such as synthetic resin, has a curved plate shape having an inner surface 3 a that forms a curved surface along the outer circumferential surface 2 a of the utility pole 2, and the circumferential direction of the utility pole 2 The length in the vertical direction is sufficiently longer than the width along the line. The width in the circumferential direction of the outer circumferential member 3 is such that, for example, when a plurality of (eight in the example of FIG. 1) outer circumferential members 3 are arranged at intervals from each other along the outer circumferential surface 2a of the utility pole 2 The interval between the members 3 is formed to be substantially the same as the width of the outer peripheral member 3.

  In the outer peripheral member 3, through holes 3 b penetrating in the width direction (circumferential direction of the utility pole 2) are provided at three locations, the upper and lower end portions and the center in the vertical direction. A binding band 8 that is wound around the utility pole 2 in order to fix the outer peripheral member 3 to the utility pole 2 is inserted into the through hole 3b.

The screw 4 has conductivity, and is screwed onto the outer surface 3c of the outer peripheral member 3 so as to protrude from the outer surface 3c with a space in the vertical direction. Since the screw 4 is screwed together without penetrating the outer peripheral member 3, the tip of the screw 4 is not in contact with the utility pole 2.
The conductive wire 5 is an uncovered bare wire and is connected to the positive electrode of the voltage application device 6.

  The voltage application device 6 is fixed to the utility pole 2 and includes a power source, a switch, a timer, and the like, and can apply or cut off the voltage to the conductive wire 5 according to switch operation or a set termer. The ground wire 7 is connected so as to connect the negative electrode of the voltage application device 6 and the electrode 9 embedded in the ground.

  The plurality of outer peripheral members 3 of the snake climbing prevention device 1 are brought into contact with the outer peripheral surface 2a of the utility pole 2 and the three binding bands 8 inserted through the respective through holes 3b are bound together. It is held by the utility pole 2. Two screws 4 are screwed to each outer peripheral member 3 at intervals in the vertical direction, and a plurality of screws 4 positioned on the upper side of each outer peripheral member 3 and positioned on the lower side. A plurality of screws 4 projecting substantially radially from the utility pole 2.

  Conductive wires 5 are wound around the screws 4 positioned on the upper side and the screws 4 positioned on the lower side, and the conductive wires 5 are connected in a ring shape so as to surround the utility pole 2. The upper conductive line 5 and the lower conductive line 5 are connected by a conductive line 5a at at least one place in the circumferential direction of the utility pole 2, and the upper conductive line 5, the lower conductive line 5, and the upper and lower conductive lines 5 Is connected to the positive electrode of the voltage application device 6, so that a positive voltage is applied to all of the conductive wires 5. The

  The snake climbing prevention device 1 applies a voltage to the upper and lower conductive wires 5 surrounding the utility pole 2 and the conductive wires 5 connecting the upper and lower conductive wires 5 by switching on the voltage application device 6, and When the snake climbs the utility pole 2 as a clue, or when it touches any one of the upper conductive wire 5, the lower conductive wire 5, and the upper and lower conductive wires 5, a current flows through the snake. Will be given a blitz.

  According to the snake climbing prevention device 1 of the present embodiment, since the screw 4 protrudes from the outer periphery of the utility pole 2, it is possible to climb the snake to the utility pole using the habit that the snake rises with the protrusion as a clue. is there. And the screw 4 has electroconductivity, the voltage is applied to the conductive wire 5 connected to the screw 4 by the voltage application device 6, and the concrete which comprises the utility pole 2 also has fixed electroconductivity. . For this reason, when a snake contacts the screw 4, a current flows from the screw 4 to the ground through the snake and the concrete of the power pole, so that it is possible to give an electric shock to the snake. For this reason, it is possible to more reliably prevent the snake from climbing.

  In addition, since the conductive wire 5 connecting the plurality of screws 4 provided in the circumferential direction of the utility pole 2 surrounds the utility pole 2 in the circumferential direction, it is possible to prevent the snake from climbing from any direction.

  Further, in this embodiment, since the outer peripheral member 3 that is an insulating member is provided on the outer periphery of the electric pole 2 made of concrete having conductivity, the conductive screw 4 and the conductive wire 5 provided on the outer peripheral member 3 and Even when a short circuit occurs between the electric pole 2 made of concrete and the snake, it is possible to give an electric shock to the snake. For this reason, even if it is a position away from the ground, it is possible to make an electric shock to the snake by grounding through the concrete electric pole 2.

In the said embodiment, although the example which connected the electroconductive wire 5 to the screw 4 made to protrude from the electric pole 2 substantially radially so that it encloses the electric pole 2 was demonstrated, it does not necessarily need to be connected cyclically. For example, a conductive wire connected to the voltage application device may be connected to one screw protruding from the utility pole via the outer peripheral member. Even in this case, it is possible to give an electric shock to a snake that rises with a clue of a screw.
Moreover, you may provide not only the screw 4 but the electroconductive member which protrudes from the outer peripheral member 3. FIG.

  Moreover, in the said embodiment, although the example which connected the electrically conductive wire 5 connected cyclically | annularly so that the utility pole 2 might be enclosed up and down was demonstrated to two places of an up-down direction, it is not restricted to this, and it exists in one place of an up-down direction. Alternatively, one of the two conductive wires may be connected to the voltage application device and the other may be grounded. Alternatively, three or more conductive wires may be provided in the vertical direction, and one of two adjacent conductive wires may be connected to the voltage application device and the other may be grounded.

  In the above embodiment, the electric pole 2 is made of concrete. However, the present invention is not limited to this. For example, the electric pole 2 may be made of an insulating member such as wooden or synthetic resin. In this case, since the surface of the utility pole itself is an insulating portion, a conductive screw or the like may be directly screwed onto the utility pole to connect the conductive wire. In this case, the conductive wire is placed at a low position so that the ground and the conductive wire can be short-circuited by the snake, or the grounded conductive wire is appropriately spaced from the conductive wire connected to the voltage application device. It is desirable to provide them separately.

  In addition, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
