Abstract

(57) [Summary] [Purpose] To prevent climbing plants such as vines and small animals such as snakes from climbing along utility pole branches. [Structure] Cylindrical body 2 which can be rotatably mounted on a utility pole branch line 5.
In addition, the three prevention plates 3 were radially arranged to constitute the climbing prevention tool 1 for a utility pole branch line. At this time, the length and the arrangement angle of these prevention plates 3 may be equal to each other so that the center of gravity of the climbing prevention tool 1 for a utility pole branch line may coincide with the axial center of the cylindrical body 2. The arranging angles of the sheaths may be unequal, and the center of gravity of the climbing preventive tool 1 for utility pole branch lines may be decentered from the axis of the tubular body 2. As a result, it is vibrated, swung, and rotated by external forces such as wind and climbing plants. As a result of the structure in which the three prevention plates 3 are radially arranged in the tubular body 2, the mountable position when mounted on a branch line including the Y branch line and used is expanded in a wide range.

[Problems to be solved by the device]

 However, in this case, the effect of preventing climbing was not always sufficient because it was fixed to the utility pole branch line, whether it was bowl-shaped or cylindrical.

In addition, when used by being attached to the Y branch line, there are cases where the two climbing prevention tools for utility pole branch lines interfere with each other and cannot be attached. That is, since the distance between the branch lines at the installation position of the climbing prevention tool for utility pole branch lines needs to be wider than the diameter of the climbing prevention tool for utility pole branch lines, there is a disadvantage that the mountable position is limited. .

In view of the above circumstances, the present invention provides a climbing prevention tool for utility pole branch lines, which has a sufficient effect of preventing climbing and can be attached and used at any position on a branch line including a Y branch line. The purpose is to

[Means for Solving the Problems]

 According to the present invention, if the pole pole line that a climbing plant tries to climb is vibrated, the climbing speed becomes slower, and if the vine winding direction is reversed, the pole is separated from the pole pole line. We paid attention to the property that the branches stick and stick to each other when they come into contact with a fixed object, thereby forming a footrest and climbing.

That is, the present invention is a climbing prevention device (1) for a utility pole branch line that is attached to a utility pole branch line (5) and has a tubular body (2) rotatably attached to the utility pole branch line. Two to several prevention plates (3) are radially arranged on the cylindrical body.

Further, the center of gravity of the cylindrical body (2) is made eccentric.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a climbing prevention device for utility pole branch lines according to the present invention, FIG. 2 is an enlarged side view of the climbing prevention device for utility pole branch lines shown in FIG. 1, and FIG. 3 is a utility pole shown in FIG. FIG. 4 is a perspective view showing a state in which a branch line climbing prevention device is attached to a utility pole branch line, and FIG. 4 is a diagram showing a state in which the utility pole climbing prevention device shown in FIG. 1 is attached to a Y branch line, and FIG. 5B is an enlarged side view, FIG. 5 is a side view showing another embodiment of the climbing prevention device for utility pole branch lines according to the present invention, and FIG. 6 is yet another embodiment of the climbing prevention device for utility pole branch lines according to the present invention. FIG. 7 is a perspective view showing yet another embodiment of the climbing prevention device for utility pole branch lines according to the present invention.

As shown in FIGS. 1 and 2, a climbing prevention tool 1 for a utility pole branch according to the present invention is made of synthetic resin or the like, and has a cylindrical body 2 at the center thereof. 2 has three prevention plates 3 (3A, 3B, 3C) arranged radially. The center of gravity of the climbing prevention tool 1 for utility pole branch lines does not coincide with the axis of the tubular body 2 and is eccentric. Various methods can be considered to make the center of gravity of the climbing prevention tool 1 for utility pole branch lines eccentric. For example, the angles formed by the three prevention plates 3 may be unequal (for example, the prevention plate 3A and the prevention plate 3A). The angle between the prevention plate 3B and the prevention plate 3C may be set to 130 °, the angle between the prevention plate 3B and the prevention plate 3C may be set to 100 °, and the angle between the prevention plate 3C and the prevention plate 3A may be set to 130 °). By making the heights unequal, the center of gravity of the climbing protection device 1 for utility pole branch lines can be made eccentric.

It should be noted that the prevention plate 3A has a structure in which it can be separately opened at its center plane, and the climbing prevention tool 1 for a utility pole branch line can be attached to the utility pole branch line through the opening. Further, since the hook portion 3a is formed on the prevention plate 3A, the utility pole branch line climbing prevention tool 1 attached to the utility pole branch line does not fall off.

Since the climbing prevention tool 1 for a utility pole branch line according to the present invention has the above-described structure, when using the climbing prevention tool 1 for a utility pole branch line, first, as shown in FIG. After installing the climbing prevention tool 1 for the utility pole branch line at the predetermined position, attach fasteners 6 to the utility pole branch line 5 portions on the upper and lower sides of the climbing prevention tool 1 for the utility pole branch line, respectively, to prevent the climbing prevention tool 1 for the utility pole branch line. Up and down (movement of utility pole branch line 5 in the axial direction) is restricted.

The utility pole climbing climbing preventive tool 1 mounted on the utility pole branch line 5 rotates around the tubular body 2 in response to wind force. At this time, the center of gravity of the utility pole climbing climbing preventive tool 1 is Since it is eccentric, it vibrates, sways, and rotates, which can prevent climbing plants such as vines and small animals such as snakes from climbing along the utility pole branch line 5. Further, it is possible to prevent climbing plants and small animals from climbing in a windless state or even when there is not enough wind to rotate the pole pole climbing preventive tool 1 even in the presence of wind.

That is, in the normal state, the climbing prevention tool 1 for utility pole branch lines stops with its center of gravity located at the lowest position, but climbing plants and small animals travel along the utility pole branch line 5 and climb up for utility pole branch lines. When climbing up to the preventive tool 1, the climbing preventive tool 1 for utility pole branch lines is rotated by the climbing of the climbing plant or small animal. Then, the position of its center of gravity becomes higher, and the reaction causes it to rotate in the opposite direction in an attempt to return to the original state. Since the climbing plants or small animals are shaken off by the vibrations accompanying the rotation at this time, further climbing is prevented or delayed.

By the way, as shown in FIG. 4, the climbing prevention tool 1 for utility pole branch lines can be mounted in a stack even when two utility pole branch lines 5 are adjacent to each other to form a Y branch line. At this time, if the distance L1 between the utility pole branch lines 5 and 5 is wider than the length of the prevention plate 3, it can be attached and used at any position.

In addition, in the above-mentioned embodiment, although the center of gravity is described as the climbing preventive tool 1 for a utility pole branch line which is eccentric from the axial center of the cylindrical body 2, when it is used in a place where the wind is always blowing, Even the climbing preventive tool 1 for a utility pole branch line whose center of gravity coincides with the axis of the cylindrical body 2 vibrates, swings, and rotates due to the wind, and thus prevents climbing plants and small animals from climbing.

Further, in addition to the climbing preventive tool 1 for a utility pole branch line as shown in FIG. 2, for example, as shown in FIG. It is also possible to fix it with a tool such as the one and use it as the climbing prevention tool 1 for utility pole branch lines. Alternatively, it is also possible to bond three substrates 7 having a substantially V-shaped cross-section to each other to form the climbing prevention tool 1 for a utility pole branch line.

Further, in the above embodiment, the climbing prevention tool 1 for utility pole branch lines having the three prevention plates 3 has been described, but the number of the prevention plates 3 is not limited to three in the present invention. For example, as shown in FIGS. 6 and 7, two or four prevention plates 3 may be provided, or five or more prevention plates 3 may be provided. However, when the number of the prevention plate 3 is one, smooth rotation of the prevention plate 3 cannot be expected, so the effect of preventing climbing is weakened. On the contrary, if the number of the prevention plates 3 is too large, the adaptability to the Y branch line is reduced. Therefore, the number of the prevention plates 3 is preferably 2 to several.

[Effect of device]

 As described above, according to the present invention, the climbing prevention tool 1 for a utility pole branch line that is used by being attached to the utility pole branch line 5 includes the cylindrical body 2 that can be rotatably attached to the utility pole branch line 5, Since the cylindrical body 2 is configured by arranging two to several prevention plates 3 in a radial pattern, the climbing prevention tool 1 for utility pole branch lines vibrates, swings, and rotates due to the wind, so it is excellent in the climbing prevention effect. It is possible to provide a climbing prevention tool 1 for utility pole branch lines. Moreover, since the climbing prevention tool 1 for the utility pole branch line has a structure in which two to several prevention plates 3 are radially arranged on the tubular body 2, when it is attached to a branch line including the Y branch line and used, The mountable position expands over a wide range.

When the center of gravity of the climbing preventive tool 1 for the utility pole branch is eccentric from the axial center of the cylindrical body 2, the climbing preventive tool 1 for the utility pole branch line 1 is caused not only by the wind but also by the climbing plants themselves. Since the plant vibrates, oscillates, and rotates, it is possible to prevent climbing plants and small animals from climbing even under no wind or breeze.
