Description

  TECHNICAL FIELD The present invention relates to a climbing prevention apparatus for climbing plants, and a climbing prevention apparatus for climbing plants that suppresses climbing of climbing plants along a branch line supporting a power pole standing on the ground. About.

  The applicant jointly completed and filed a scooping prevention device that prevents climbing plants from scooping up along a branch line that supports a structure such as a utility pole erected on the ground (Patent Document). 1). This climbing prevention device for climbing plants is a longitudinal body of a cable body (for example, a stranded steel wire cable or the like is used specifically) that functions as a branch line stretched between the ground and a utility pole. A cylindrical covering attached to the middle part of the cable body is provided so as to cover the middle part. A slit is formed in a part around the axial center of the covering, and the middle part of the cable body is inserted into the covering through the cutting. Moreover, the effect of an apparatus is heightened by suppressing the growth of a plant by giving the repellent (growth inhibitor) of the sexual plant to the outer surface around the axial center of a covering.

  In addition, as a device for preventing climbing of a climbing plant with a simple structure, there has been proposed a curl winding preventer for a utility pole branch line (Patent Document 2). This curl-winding prevention tool is a synthetic resin extrusion molded product obtained by integrally molding a plate-like board blade and a branch line mounting cylinder, and is used so that the branch line mounting cylinder portion is fitted along the branch line. A prayer (a climbing plant) that crawls up from the ground cannot wrap around a plate feather portion having a predetermined width and cannot extend a vine above the device.

JP 2014-217301 A Utility Model Registration No. 3123795

  In the scooping prevention device disclosed in Patent Document 1, a slit is formed over the entire axial direction of a cylindrical covering body having a predetermined diameter in order to facilitate the attachment work of the branch line to the cable body, By inserting the striatum, holding the striatum, and applying a repellent of vines to the outer surface of the covering, climbing of the vines is prevented. In this apparatus, firstly, it is considered to prevent creeping plants from creeping up with a cylindrical covering, and further to suppress the growth of plants with a repellent applied to the outer periphery of the covering. In order to ensure that the coating does not wrap around the covering, the diameter of the covering must be sufficiently large. Therefore, in order to prevent the climbing of the vine in various climbing plants, the diameter of the covering must be increased, which causes a problem that the apparatus is increased in size and weight.

  On the other hand, the curl prevention tool disclosed in Patent Document 2 has an advantage that, compared with Patent Document 1, it is possible to increase the winding effect of the climbing plant only by increasing the width of the blade. However, since this preventer is an integrally molded product of synthetic resin, it can only deal with a wire rod (strand body) that fits into a branch line mounting cylinder molded to a predetermined size. Therefore, for example, it cannot attach to outer peripheral surfaces, such as a covering body indicated by patent documents 1.

  Therefore, the object of the present invention is to solve the problems of the conventional techniques described above, and to attach the tubular body of the climbing prevention apparatus for climbing plants having a tubular body, which is directly attached to the cable body of the branch line of the utility pole.

An apparatus for preventing creeping of climbing plants, wherein the sheet main body has a roll portion wound around an intermediate position of the cable body, and a predetermined hanging width connected to the roll portion. In addition, the shape retaining member has a flag-like portion disposed on the edge, and the winding and scooping of the climbing plant are suppressed by the shape-retained flag-like portion.

  It is preferable to apply the growth inhibitor of the vine plant to the flag-shaped part.

  The sheet body is preferably made of a mesh sheet.

  It is preferable that the roll portion is wound so as to cover an outer periphery of a cylindrical support attached to the cable body, and is fixed and held on the cylindrical support by a plurality of strips.

  It is preferable that the shape-retaining member is a small-diameter bar attached along the edge of the flag-shaped portion.

  It is preferable that the small-diameter bar is accommodated in a bag-shaped portion formed along the edge of the flag-shaped portion.
