JP4517052B2 - Climbing prevention tool for vines - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vine plant used to prevent climbing of vine plants that cause ground faults and short-circuits (short-circuits) with a transformer or the like installed on a power pole supporting a power pole. It relates to climbing prevention devices. (Hereafter referred to as prevention tool.)
[0002]
[Prior art]
Conventionally, various types of preventive devices such as a cylindrical box or a bowl-shaped cap have been proposed.
[0003]
These preventive tools have the effect of increasing the diameter so as to block the destination of the vines and becoming an obstacle, and cannot reach the upper transformer.
[0004]
However, these conventional preventive devices are attached with the length and diameter of the approximately cylindrical body according to the rising height of the vine plant so as not to climb the branch line, but rarely mischief such as strong winds and birds In some cases, the vines overcame the protective devices gradually because the vines and varieties of plants (waste, ivy, wig, etc.) and those with remarkable growth sometimes get over.
[0005]
In addition, when a pole operator needs to monitor the climbing status of the vines by patrol, and depending on the climbing status, the vines must be logged. Expenses and burdens on workers will increase.
[0006]
Increasing the diameter of the prevention device can surely prevent climbing of vines, but the prevention device cannot be attached when there is no distance between adjacent branch lines. In addition, an entirely new mold was produced to increase the diameter, which caused an economic burden on the manufacturing side.
[0007]
In addition, even if climbed by any chance, it is necessary to extend the total length of the preventive tool, paying attention to the fact that it is possible to delay the time to reach the upper transformer and the like, thereby reducing the work interval of the felling contractor.
[0008]
[Problems to be solved by the invention]
This invention is made | formed in view of such a problem, and it aims at providing the prevention tool which can change the shape which maintained the effect of prevention of a vine plant as much as possible, and restrained mold investment.
[0009]
[Means for Solving the Problems and Effects of the Invention]
The invention according to claim 1, which was made to achieve such an object, is a preventer that is attached to a branch line that supports a power pole and the like and can prevent climbing of vines,
A vine plant having a structure in which a fixing device that can be fixed to a branch line and a substantially cylindrical body that can cover the predetermined length of the branch line by incorporating the fixing tool can be connected in the longitudinal direction. No climbing prevention device.
[0010]
That is, according to the prevention tool of the present invention (Claim 1), it takes time to completely get over the prevention tool even if the vine plant starts to get over the prevention tool by increasing the total length of the fixing tool. Therefore, since it takes time to reach the upper transformer, etc., it is possible to earn time until the felling contractor cuts.
[0011]
Claims 2 and 3 show a specific connecting structure of the preventive tool, and are listed as the cheapest method in manufacturing the mold.
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings while matching the assembly procedure.
FIG. 1 is a perspective view showing the inside of the preventive device according to the first embodiment to which the present invention is applied, in a state before assembling, when the two are connected.
[0012]
As shown in FIG. 1, after the opposing semi-cylindrical boss portion 12 of the other protective device main body 11 facing the semi-cylindrical boss portion 2 of the present embodiment facing the semi-cylindrical boss portion 2 of this embodiment is combined into a cylindrical shape, It inserts from the front-end | tip part of the cylindrical boss | hub part 5 in which the stop 6 was formed so that it may not isolate | separate. The same applies to the other bosses 3 and 13, 4 (not shown) and 14. Thereafter, the connecting plate 7 is attached to the boss portion 8 with the hole of the main body 1 of the prevention tool and the boss portion 18 with the hole of the main body 11 of the prevention device with the screw 10. Similarly, the connecting plate 7 is attached to the other boss 9 with holes (not shown) and the boss 19 with holes.
[0013]
After assembling the connecting plate 7 and the locking tool 6, the branch line fixing tool 21 is attached to the prevention tool main bodies 1 and 11 to the holed boss parts 22 and 23 having the same shape as the holed boss parts 8 and 18, respectively.
[0014]
Thereafter, the hinge part (female part) 24 and the hinge part (male part) 25 are fitted into the semi-cylindrical prevention device 26 and another set of semi-cylindrical prevention devices 27. Then rotate around the hinge. The size of the prevention tool at this time is 20 cm in diameter and 110 cm in length.
[0015]
The branch line is passed through the branch line through ports 30 and 31 of the prevention tool 29, and the branch part 38 is also passed through the branch line through parts 33 and 34 of the branch line fixing tool. Thus, the attachment to the branch line 38 is completed.
[0016]
Next, a method for molding each preventive device according to the embodiment will be described.
There is a single prevention device 35 which is the most basic shape.
When molding the preventive device 1, the resin of the material is prevented from flowing into the A portion of the preventive device single 35, and when the preventing device 11 is molded, the resin is prevented from flowing into the B portion. In the case where the preventive tool 32 is molded, the resin is prevented from flowing into both the A part and the B part.
[0017]
Next, the usage example when connecting 3 using the intermediate | middle member prevention tool of embodiment is demonstrated.
[0018]
The prevention tool single 31 has the same shape as the prevention tool single 1, and the prevention tool single 33 has the same shape as the prevention tool single 11. The preventive tool 32 is formed by the above method. Subsequent assembly is performed in the same manner as described above.
The size of the prevention tool at this time is 20 cm in diameter and 150 cm in length.
[0019]
As mentioned above, although the Example of this invention was described, this invention is not limited to the said Example, It can take a various aspect. The preventive tool may be an insulating material, and polypropylene or polyethylene may be used as a main material.
