The tubular body is formed so as to have a thickness and a length such that the fertile plant is not rolled up, and is fixed to a part of the branch line and arranged. FIG. 7 is an explanatory view showing a state in which a conventional dwarf plant roll-up prevention device is disposed on a branch line. As shown in FIG. 7, the lower part of the utility pole 11 and the branch line 12 is buried in the ground 13, and the branch line guard 14 is provided on the ground surface side of the branch line 12 exposed to the ground. The dwarf plant roll-up prevention device 15 is fixedly provided on a part of the branch line 12 exposed upward from the branch line guard 14. The branch line 12 is divided into two by the insulator 16, and the insulator 16 prevents the current from flowing through the branch line 12 from the electric wire or the charging portion of the utility pole 11.

  The dwarf plant rolling-up prevention device 15 is a cylinder formed to have a thickness and a length such that the dwarfing plant 17 is not rolled up, and the dwarfing plant 17 may be wound around the dwarf plant rolling-up prevention device 15 It can not be done. That is, even if the dwarf plant 17 extends from the ground 13 and reaches the dwarf plant rolling-up prevention device 15, the dwarf plant 17 can not extend further upward, and the electric wire of the utility pole 11 and the charging portion Is prevented from reaching.

  Here, as a dwarf plant rolling up prevention device, the device body of the dwarf plant rolling up prevention device is fixed to a branch line by a cord locking portion, the cross section of the device body is formed into a polygon, and a dwarf plant is wound There is one in which the contact surface is made smaller to prevent wrapping of the fertile plant (see, for example, Patent Document 1). In addition, a wind turbine (rotational force application mechanism) for applying rotational force to the rotating body rotatably attached to the branch line is provided, and the free fall of the rotating body is restricted by the stopper fixed to the branch line. An uneven part formed on the outer periphery of the rotating body collides with a dwarf plant which is going to be rolled up, and the dwarf plant is guided in a direction away from the center of the rotating body so that it hangs down under its own weight. There are some which are intended to more reliably prevent the rolling up of fertile plants with respect to (see, for example, Patent Document 2).

FIG. 1: is explanatory drawing which shows the state which has arrange | positioned the fertile plant rolling-up prevention apparatus based on 1st Embodiment of this invention on a branch line. 2 is a cross-sectional view taken along the line X-X in FIG. 1, and FIG. 2 (a) is a cross-sectional view showing a state in which the fertile plant is not wound, and FIG. 2 (b) is in which the fertile plant is wound It is sectional drawing which shows a state. The same elements as in FIG. 7 are assigned the same reference numerals and redundant explanations will be omitted.

  In FIG. 1, the device for preventing plant rolling up according to the first embodiment of the present invention continuously arranges a plurality of cylindrical bodies 18 from the lower portion to the upper portion of the branch wire 12 to form a cylindrical array 19. Formed and configured. FIG. 1 shows the case where two cylindrical bodies 18 are arranged in the branch line 12 with the forceps 16 of the branch line 12 interposed therebetween. Winding portions 20 are provided at both ends of the cylindrical body 18.

  In FIG. 2A, the cylindrical body 18 is composed of a cylindrical body 21 and a projection 22. The cylinder body 21 is rotatably disposed so that the radius of the hollow portion 23 hollowed out is larger than the radius of the branch wire 12 so as to surround the branch wire 12. FIG. 2A shows a state in which the branch line 12 is in contact with the inner surface of the hollow portion 23. This is because the cylindrical body 21 is in contact with the branch 12 by the weight of the cylindrical body 21.

  The protrusion 22 is provided so as to protrude from the outer peripheral surface of the cylindrical body 21. The protrusions 22 will be described later. On the other hand, an opening 24 is provided in the cylindrical body 21 in the axial direction of the cylindrical body 21. The opening 24 is an insertion port for inserting the branch wire 21 into the hollow portion 23.

  The size of the opening 24 is formed to be large enough to insert the branch 12 (a little larger than the diameter of the branch 12). When the cylindrical main body 21 is formed of a synthetic resin having elasticity, the size of the opening 24 is made the same as or slightly smaller than the diameter of the branch 12, and the opening 24 is expanded to insert the branch 12. Thereby, it can prevent that the cylinder main body 21 remove | deviates from the branch line 12. As shown in FIG. FIG. 1 shows the case where the opening 24 is smaller than the diameter of the branch 12.

  As shown in FIG. 2 (b), the protrusion 22 forms a clearance 25 for inserting the blade edge and cutting the fertile plant 17 when the fertile plant 17 is wound around the cylindrical body 21 and ascends. 2 (a) and 2 (b) show the case where five protrusions 22 are provided. That is, a total of five protrusions 22 are provided on the outer peripheral surface of the cylindrical main body 21 and three at the both edges of the opening 24. The protrusions 22 are generally provided on the outer peripheral surface at intervals of π / 2 (90 °), and the protrusions 22 on both edges of the opening 24 are provided keeping the distance of the size of the opening 24. . The blade is inserted into the gap 25 formed by the projection 22 to cut the fertile plant 17. Moreover, the contact surface to the cylinder main body 21 with which the fertile plant 17 was wound is made small by having provided the projection part 22. As shown in FIG. That is, since the location where the fertile plant 17 contacts is the tip of the protrusion 22, rolling up of the fertile plant 17 can be suppressed.

  In FIG. 1, the winding portions 20 at both ends of the cylindrical body 18 are formed by, for example, winding an adhesive tape at both ends of the cylindrical body 21 after inserting the branch wire 12 into the hollow portion 23 of the cylindrical body 21. Ru. Thereby, the opening 24 is reliably prevented from opening, and even when the opening 24 is larger than the diameter of the branch wire 12, the cylinder main body 21 is prevented from being detached from the branch 12.

  FIG. 3: is explanatory drawing of the removal operation of the fertile plant which rolled up to the fertile plant rolling-up prevention apparatus of FIG. The same elements as those in FIG. In FIG. 1, the fertile plant 17 extends from the ground 13 and the branch guard 14, the cylinder 18 of the cylindrical array 19 on the lower side of the fertile plant roll up prevention device, the forceps 16, and the fertile plant roll up prevention The cylindrical body 18 of the cylinder array 19 on the upper side of the device and the power pole 11 are shown in a rolled up state.

Therefore, as shown in FIG. 1, although it takes time to roll up to the utility pole 11, it is necessary to remove the fertile plant 17 which rolled up the cylinder 18.

  Then, as shown in FIG. 3, the worker 26 performs the removal operation of the ungulate plant 17. At that time, the worker 26 inserts the cutting edge into the gap 25 between the cylinder main body 21 of the cylinder 18 and the green plant 17 to cut the green plant 17, but the branch 12 is the cylinder main body. As it is surrounded by 21, the cutting edge does not damage the branch line 12. That is, the ungplants 17 wound around the cylindrical body 18 can be easily cut without damaging the branch lines 12. Further, at that time, the cylinder body 21 of the cylinder 18 can rotate the cylinder body 21 because the radius of the hollow portion 23 hollowed out is larger than the radius of the branch wire 12 and surrounds the circumference of the branch wire 12. Thus, by pulling the cut fertile plant 17, the main body 21 of the cylinder can be rotated and the fertile plant 17 wound around the can 18 can be easily removed.

  According to the first embodiment, since the cylinder array 19 formed by continuously arranging the plurality of cylinders 18 from the lower portion to the upper portion of the branch wire 12 is provided, the cylinders 18 are arranged. The branch line 12 is not exposed at the point, and the green plant 17 wound around the cylindrical body 18 can be easily cut with the cutting edge without damaging the branch line 12. Further, since the cylindrical body 21 is rotatable, pulling the cut fertile plant 17 allows the cylindrical body 21 to be rotated and the fertile plant 17 wound around the cylindrical body 18 to be easily removed. Furthermore, since the cylinder 18 can insert the branch wire 12 into the hollow portion 23 through the opening 24 provided in the axial direction, the cylinder 18 can be easily attached to the branch wire 12, and further, the cylinder 18 Since the winding portion 20 is formed at both ends of the sleeve 18, the cylinder 18 does not come off the branch wire 12.

  Next, a second embodiment of the present invention will be described.

Even if the cross section is a projection 22 having a triangular shape, as in the case of the first embodiment, the projection 22 inserts a blade edge when the fertile plant is wound around the cylindrical body 18 and cuts the fertile plant. The gap 23 can be formed. This is because the cross section of the cylindrical body 18 is star-shaped.

  Further, the cylindrical body 18 in the second embodiment is configured by connecting two divided bodies 27 by a hinge 28, and a locking portion 29 for locking the two divided bodies 27 at the facing portion of the hinge 28 is used. Have. Then, when the two divided bodies 27 are joined together, the cylinder main body 21 is formed to surround the branch line 12, and the facing portion of the hinge 28 is locked by the locking portion 29 to form the cylinder 18. . The locking portion 29 may be locked by fitting, or may be locked by adhesive tape or screwing.

  According to the second embodiment, when the two divided bodies 27 connected by the hinge 28 are joined together, the cylindrical body 21 is formed to surround the branch line 12. Therefore, the cylindrical body 18 can be easily attached to the branch line 12, and the branch line 12 is covered with the cylindrical body 18 at the portion where the cylindrical body 18 is disposed. Further, since the two divided bodies 27 are locked by the locking portions 29 at the facing portion of the hinge 28, the branch wires 12 are positioned in the hollow portion 23 of the cylinder 18 without the two divided bodies 27 being detached. Can.

  Next, a third embodiment of the present invention will be described.
