This disclosure relates to methods and apparatuses for limiting the growth of vines.
Guy wires are often used to add stability to free-standing poles and other structures, including, for example, telephone and power line poles. Vines are plants that will grow along rigid structures, including guy wires. This can be problematic because the weight of the vine may damage the guy wire or the structure that the guy wire is stabilizing. Some vines, notably kudzu, can even climb the entire guy wire and then envelope telephone or power lines, which may interfere with signal or power transmission.
Kudzu often climbs up guy wires and either weaves into the hot wire or causes the pole to fall, causing an interruption in the power supply. Electric utilities must spend substantial resources to clear kudzu from power transmission lines.
A method of restricting the growth of vines along a guy wire is provided. The method includes possessing a member defining a tapered chamber having first and second openings. The chamber is tapered such that the chamber is widest at the first opening. The method further includes positioning the member such that the guy wire extends through the first opening, the second opening, and the tapered chamber.
In use, the growing end of a vine climbing the guy wire will enter the chamber through the first opening. Once in the chamber, the tapered inner surface of the member will deflect the growth of the vine downward, causing the vine to succumb to its own weight. Furthermore, in one embodiment, the member defining the chamber is substantially opaque. The vine will sense the lack of light inside the chamber, which will also stop the vine from further growth along the guy wire.
Accordingly, the method provides a physical barrier that will effectively stop the growth of vines along guy wires. The method is cost-effective compared to the prior art because a single application of the member to a guy wire may prevent the growth of vines for several years, thereby eliminating the need to clear vine growth manually or through herbicides several times per year.
A corresponding system for restricting vine growth is also provided.
The above features and advantages and other features and advantages of the present disclosure are readily apparent from the following detailed description of the best modes for carrying out the disclosure when taken in connection with the accompanying drawings
Referring to the Figures, wherein like reference numbers refer to like components throughout, a vine inhibiting cone assembly 8 includes a member 10. The member 10 includes a first part 14 that defines a frusto-conical outer surface 18 and a frusto-conical inner surface 22. The member 10 also includes a second part 26 that defines a cylindrical outer surface 30 and a cylindrical inner surface 34. The frusto-conical inner surface 22 and the cylindrical inner surface 34 cooperate to define a chamber 38 that extends through the member 10.
The first part 14 of the member 10 defines a first opening 42 to the chamber 38. The second part 26 of the member 10 defines a second opening 46 to the chamber 38. The chamber 38 includes a tapered, frusto-conical portion 50 defined by inner surface 22, and a cylindrical portion 54 defined by inner surface 34. The diameter of the frusto-conical portion 50 of the chamber 34 is largest at the first opening 42 and decreases with proximity to the cylindrical portion 54. The cylindrical portion 54 of the chamber 34 has a constant diameter between the frusto-conical portion 50 and the second opening 46.
It should be noted that, though the tapering portion 50 of the chamber 38 is frusto-conical, any tapering geometry may be employed within the scope of the claimed invention. For example, the tapering portion 50 and surface 22 may be a parabaloid such that the width of the chamber is wider at opening 42 and narrows with distance from the opening 42.
The member 10 also includes two edges 58, 62 that extend between the first and second openings 42, 46. Prior to installation on a guy wire, edges 58, 62 cooperate to define a third opening 66 therebetween, as shown in
Referring to
A clamp 90, such as a radiator clamp, is applied to the cylindrical outer surface 30 such that the clamp 90 exerts a compressive force radially inward on the second part 26. The compressive force is transmitted through the member 10 to the elastomeric bushing member 86 and the guy wire 70. Accordingly, the clamp 90 retains the member 10 in place on the guy wire 70 and also ensures that the second opening 46 remains obstructed.
