Description

  [Technical Field] The present invention relates to an electric pole branch line anti-spinning device attached to an electric pole branch line in order to prevent the electric pole branch line from rolling up.

  A branch line is attached to the utility pole to prevent the utility pole from tilting, breaking or collapsing. When the branch winds around the branch line, it rolls up along the branch line, and when it reaches the electric wire, a power failure occurs due to a ground fault. Therefore, in order to prevent the curl from rolling up, a curl-winding prevention tool is attached to the branch line.

  As a curl winding prevention tool for power pole branch lines, the curl rolls up around the power pole branch line while drawing an arc, so that the conventional curl prevention tool is difficult to wind the tip of the curl as seen in the shade and cylindrical shape. The shape in which a protective wall is provided in a circular shape so as to protect a range equidistant from the branch line is the mainstream. For example, in Patent Document 1, as shown in FIG. 3A, a cylindrical peripheral wall 31 made of synthetic resin, two end walls 32 that close both axial ends of the peripheral wall 31, and an axial direction of the peripheral wall 31. There is disclosed a vine plant roll-up prevention device 30 having a plurality of holders (not shown) supported by utility pole branch lines 6 provided at intervals from each other.

Further, in Patent Document 2, as shown in FIG. 4, the upper end portion is provided with an inclined portion 41 extending along the utility pole branch line 6, and a plurality of air holes 42 are formed in the surface to prevent shaking due to strong wind. A shift-up preventing plate 40 is disclosed in which a plate 43 fixed to a utility pole branch line 6 is suspended from a pipe 44 by a wire 45 or the like.

  Since the cylindrical prevention device of the cited document 1 has a cylindrical half-crack structure and has a cavity inside, as shown in FIG. 3B, a strong wind such as a typhoon blows into the inside and deforms. Or fall off and must be replaced. Furthermore, since there are many members such as end walls, holders, and fasteners, the manufacturing process is complicated and the manufacturing cost increases, and since the volume (capacity) is large, the transportation cost and the management cost are high. ing.

  Moreover, since the prevention plate of the cited document 2 has a structure in which the prevention plate is suspended from the pipe fixed to the branch line with a wire, there is a possibility that the shift will roll up along the pipe. Further, since it is necessary to suspend the prevention plate on the pipe with a wire, there is a drawback that it takes time to fix the pipe and to attach the prevention plate.

  Therefore, the present invention provides a power pole branch line anti-spinning device that can reliably prevent the hoisting of the kazura, can be easily attached to the branch line, and is not deformed by a strong wind after being attached to the branch line. It is.

  The power pole branch line curl winding prevention device according to the present invention is a power pole branch line curl winding prevention device in which a branch line mounting cylinder is integrally connected to the upper end of a plate-shaped board blade. It can be opened and closed when the utility pole branch line is passed through the connecting portion, and can be rotated around the utility pole branch line as a rotation axis.

  In the above-described configuration, the branch line mounting cylinder is made of an elastic material so that it can be opened and closed, and the blades are connected to the opening and closing ends of the branch line mounting cylinder, respectively, or the branch line mounting cylinder A leaf blade may be connected to one end portion of the end portion that opens and closes, and a guide piece may be formed on the other end portion.

  In the present invention, the swaying prevention device for utility pole branch lines can be reliably prevented from being rolled up because the blades and the branch line mounting cylinder are integrally formed.

  The present invention's electric pole branch line knurl winding prevention device is plate-shaped and does not have a hollow structure having a cavity inside, and therefore does not undergo deformation such as turning up due to blowing of wind. As a result, it is possible to significantly reduce the cost and replacement work related to defective replacement compared to the conventional case. In addition, it is possible to reduce logging-related costs and prevent accidents associated with the roll-up of a fallen case.

  The knurl winding prevention device for a utility pole branch line of the present invention has an effect of swinging down a knuckle that is going to be rolled up by swinging around the branch line as a rotation axis by receiving the wind pressure.

  In addition, the electric pole branch line squeezing device of the present invention has a simple structure in which the blades and the branch line mounting cylinder are integrated, so that it can be manufactured by extrusion molding. Therefore, the manufacturing cost can be reduced as compared with the conventional case.

  In addition, the present invention's power pole branch line anti-winding device is a plate-like body, so the volume can be reduced compared to the conventional cylindrical anti-winding device, thus reducing transportation costs and management costs. it can.

  In addition, the present invention's electric pole branch line knurl winding prevention device is mounted on the utility pole branch line by simply pushing down the plate blade over the branch line and stopping it, so that the work efficiency is improved.

  Further, according to the present invention, the electric pole branch line knurl prevention device connects the blades to one end of the branch line mounting cylinder that opens and closes, and forms a guide piece on the other end, thereby reducing the amount of material used. Can be reduced.

  Hereinafter, an embodiment of a curl winding prevention tool for a utility pole branch line according to the present invention will be described with reference to the drawings.

  FIG. 1 (a) is a perspective view of a first embodiment of the electric pole branch line squeezing device according to the present invention, and FIG. 1 (b) is a perspective view showing a state where the pole pole branch line is mounted.

  In FIG. 1, the utility pole branch line curl winding prevention device of this embodiment includes a pair of opposed leaf blades 2 a and 2 b and a branch line mounting cylinder 3 that are integrally formed. A pair of opposed blades 2a and 2b are formed so as to be slightly widened to facilitate introduction of the utility pole branch line 6 between the blades 4. As a material, elastic synthetic resin, for example, polyethylene is used, and the blades 2a and 2b and the branch line mounting cylinder 3 are integrally formed by extrusion molding.

  The width of the blades 2a and 2b is 150 mm or more. As a result of verifying the widths of the leaf blades 2a and 2b with four types of widths of 100 mm, 150 mm, 200 mm, and 250 mm, there was a slight roll-up at 100 mm. At 150 mm, one roll was seen, but then it fell. Therefore, the plinth 13 that is going to wind up on the utility pole branch line 6 is transmitted to the outer sides of the blades 2a and 2b through the blades 2a and 2b, and further tries to wind up, but the width of the blades 2a and 2b is 150 mm. By setting it as the above, since the front-end | tip of the shift 13 hangs down to the ground surface by its own weight or wind pressure before the shift 13 is wound, it is possible to prevent the shift 13 from being wound around the power pole branch line shift preventive tool 1. . Note that no roll-up was observed at 200 mm and 250 mm.
