Abstract

A snow cover having a high snow fall effect is provided.
A main body 11 having an inner diameter larger than a diameter of a cable 100, a snow cut plate 12 formed on an upper portion of the main body 11, and a plate-like weight 13 formed on a lower portion of the main body 11 are provided. The snow-cut plate 12 and the weight 13 are subjected to water repellent finishing. As a result, the weight of the weight 13 causes the snow-cutting plate 12 to be perpendicular to the ground, so that the snow that accumulates on the hard-to-attach snow cover 1 is divided by the snow-cutting plate 12 and snow falls easily. Moreover, since the wind is received by the snow-cut plate 12 and the plate-like weight 13 and the cable 100 is shaken, it is possible to promote the fall of the snow accumulated on the cable 100 to which the hard-to-attach snow cover 1 is not attached.

  However, as shown in the cross-sectional view of FIG. 4, even if the surface of the hard snow ring or cable 100 is subjected to a water repellent treatment, there is a problem that the snows 200 stick to each other around the cable and do not easily fall. is there.

  This invention is made | formed in view of the above, The place made into the subject is providing the difficult snow cover which is easy to attach and has a high snow fall effect.

  A difficult snow cover according to the present invention is a hard snow cover to be attached to a cable, and has a cylindrical inner cover body having an inner diameter larger than the diameter of the cable and a water-repellent outer peripheral surface; It is characterized by having a snow cut portion disposed on the upper portion and having a water repellent finish, and a weight disposed on the lower portion of the cover main body facing the snow cut portion.

  In the present invention, a snow-cut portion that is disposed on an upper portion of a cylindrical cover body that accommodates a cable and is water-repellent processed, and a weight that is disposed on a lower portion of the cover body facing the snow-cut portion. As a result, the snow cut portion stands with respect to the ground due to the weight, so that it is possible to provide a difficult snow cover that is easy to fall because the snow accumulated on the cover body is divided.

  In the difficult snow cover, the weight is plate-shaped.

  In the present invention, by providing a plate-like weight, it is possible to sway the hard snow cover when the weight receives wind, and to encourage snow falling on the cable not attached with the hard snow cover. To do.

  In the above difficult snow cover, the cover body has an opening that can be opened larger than the diameter of the cable.

  In the present invention, it is possible to easily attach the difficult snow cover to the cable by having the opening in the cover body.

  In the difficult snow cover, it is desirable to have a stopper disposed on the cable in order to control the movable range of the hard snow cover.

  According to the present invention, it is possible to provide a difficult snow cover that is easy to attach and has a high snow fall effect.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to only those described below.

  FIG. 1 is a perspective view showing the configuration of a difficult snow cover in the present embodiment. As shown in the figure, the hard snow cover 1 includes a cylindrical main body 11, a snow cutting plate 12 at the upper part of the outer peripheral surface of the main body 11, and an outer peripheral surface of the main body 11 facing the snow cutting plate 12. This is a structure provided with a plate-like weight 13 at the bottom.

  The length of the main body 11 in the longitudinal direction is about several cm to 20 cm. The inner diameter of the main body 11 is about several mm to 1 cm, and is about several mm larger than the diameter of the cable 100 to which the hard-to-cover snow cover 1 is attached. The length of the snow-cutting plate 12 is equal to the length of the main body 11, and the height of the snow-cutting plate 12 is about several centimeters. The length of the weight 13 is also equal to the length of the main body 11. The height of the weight 13 is about twice that of the snow cut plate 12.

  As a material for the hard-to-attach snow cover 1, a polyester resin, an acrylic resin, a polypropylene resin, or the like is used. The outer surface of the hard-to-attach snow cover 1 is coated with a water-repellent material and is water-repellent. As the water repellent material, it is desirable to use a super water repellent material having a contact angle of 140 degrees or more.

  FIG. 2 is an external view showing a state where the hard snow cover 1 is attached to the cable 100. As shown in the figure, the cable 100 is accommodated inside the main body 11 when the hard snow cover 1 is attached. Since the inner diameter of the main body 11 is larger than the diameter of the cable 100, the hard snow cover 1 is movable left and right along the cable 100 and is rotatable about the cable 100. Since the weight 13 has a larger weight 13 than the snow-cutting plate 12, the difficult snow cover 1 rests with the snow-cutting plate 12 up and the weight 13 down when there is no wind. When there is snow in this state, the snow falling on the upper part of the main body 11 is unbalanced by the snow cutting plate 12 without causing the snow to stick together at the upper part of the main body 11 and falls by its own weight.

  Although it snows on the cable 100 portion where the hard snow cover 1 is not attached, since the snow landing portion on the cable 100 is divided at the place where the hard snow cover 1 is attached, the snow on the cable 100 easily falls. Become. Moreover, the fall of the snow on the cable 100 is accelerated | stimulated because the cable 100 shakes by the wind pressure which the snow-cut board 12 and the plate-like weight 13 receive, or the hard snow cover 1 shakes and moves right and left. .

  The difficult snow cover 1 is preferably attached to the cable 100 at intervals of about 2 m to 10 m. In addition, as shown in FIG. 2, by attaching the movement prevention stopper 20 to the cable 100, the left and right movable ranges of the hard snow cover 1 can be limited.

  FIG. 3 is a perspective view showing a configuration of another difficult snow cover in the present embodiment. The difficult snow cover 3 shown in FIG. 1 includes a cylindrical main body 31 having a polygonal cross section, a snow cut portion 32, and weight plates 33A and 33B, similar to the one shown in FIG. Structure.

  The plates 33A and 33B are connected to openings formed in the longitudinal direction at the lower part of the main body 31, and each of the plates 33A and 33B is held by a finger, and the opening is made larger than the diameter of the cable, thereby easily connecting the cables. It becomes possible to attach the difficult snow cover 3 to 100. After attaching the difficult snow cover 3 to the cable 100, the holes 34 formed corresponding to the plates 33A and 33B are tied with a binding band or a wire, and the plates 33A and 33B are bonded together. Thus, by providing the main body 31 with an opening that can be opened larger than the diameter of the cable 100, it is possible to easily attach the difficult snow cover 3 to the cable 100. Needless to say, it is easy to remove. Therefore, attachment and removal can be easily performed according to the snowfall situation, season, and the like.

  As shown in FIG. 3, the main body 31 of the hard-to-cover snow cover 3 may have a polygonal cylindrical shape or an elliptical cross section. The snow cut portion 32 is preferably plate-shaped so as to be perpendicular to the ground. However, for example, it may be a triangle shape having one side of two plates bonded to each other and having an inclination angle of 50 degrees or more. .

  Therefore, according to the present embodiment, the main body 11 having an inner diameter larger than the diameter of the cable 100, the snow cutting plate 12 formed on the upper portion of the main body 11, and the plate-like weight 13 formed on the lower portion of the main body 11. The body 11, the snow cut plate 12 and the weight 13 are subjected to water repellent treatment so that the weight of the weight 13 makes the snow cut plate 12 perpendicular to the ground. The snow that accumulates on the snow cover 1 is divided, making it easier to fall. Moreover, since the wind is received by the snow-cut plate 12 and the plate-like weight 13 and the cable 100 is shaken, it is possible to urge the snow falling on the cable 100 to which the hard-to-attach snow cover 1 is not attached.

  According to the present embodiment, it is possible to easily attach the difficult snow cover 3 to the cable 100 by providing the lower portion of the main body 31 with an opening that can be opened larger than the diameter of the cable 100. Thereby, the difficult snow cover 3 can be attached to the cable 100 without interrupting communication.

It is a perspective view which shows the structure of the difficult snow cover in one Embodiment. It is an external view which shows a mode that the said difficult snow cover was attached to the cable. It is a perspective view which shows the structure of another difficult snow cover in one Embodiment. It is sectional drawing which shows a mode that it snowed on the cable.
