Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater draining ring which is mounted on a plurality of electric wires installed between electric poles at intervals to disperse and drop rainwater that falls along the electric wires.

[0002]

2. Description of the Related Art Generally, an electric wire such as a distribution line or an overhead ground wire installed between electric poles is appropriately stretched so as to form a large circular arc with a certain degree of slack. . Therefore, in such an electric wire, when it rains, the rainwater that hits the electric wire is concentrated and dripped at the lowest point in the center between the electric poles.

[0003]

When the rainwater that has fallen on the long electric wires between the electric poles is concentrated and dripped in this way, a hole is made in the ground directly below, and if it is a field, it causes damage to crops. Also, if there is a roof on the house, there is a problem that the roof tiles will be damaged, and that the roof made of galvanized iron will generate a lot of noise. Therefore, an object of the present invention is to provide a rain drain ring for an electric wire, which can solve such a problem by dispersing rain water dripping from the electric wire.

[0004]

In order to achieve the above object, the present invention provides a hinge part by thinning the circumferential top of the ring body to provide a hinge part, and a lower part facing the ring part to the hinge part. Separated at the position, a pair of locking claws that engage with each other so that they can be engaged and disengaged with each other are provided oppositely, and a ridge is provided around the center of the outer peripheral surface of the ring body excluding the hinge part, and A plurality of transverse ridges are provided at substantially equal intervals on the circumferential surface to form a rain ring for electric wires.

[0005]

The ring body of the rain drain ring constructed as described above is detached from the locking claws and expanded at the cut-off end, and is attached to the electric wire at an appropriate interval to secure the locking claws to each other. Engage and fix the position, and install a plurality of poles between the poles. In this way, each of the plurality of rain drain rings attached to the electric wire hits and drops the rainwater that has fallen on the electric wire by the protrusion of the rain drain ring located at the lower part of the adjacent rain drain rings. For this reason, the rainwater that has fallen on the electric wire between the electric poles will be dispersed and dropped by the number of attached rain drain rings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a ring body formed to have a required width, and the inner diameter of the ring body 1 is selected to match the outer diameter of the electric wire to be deposited. The top of the ring body 1 is made thin to provide a hinge part 2 having elasticity, and the ring part 1 is cut off at a lower position facing the hinge part 2.
The hinge portion 2 can be expanded between the separated both ends 3a and 3b with the hinge portion 2 as a starting point.

A thin engaging piece 4 is provided on the inner peripheral side of one of the separating ends 3a, and a locking claw 5a is provided on the lower surface of the tip thereof.
Is formed. A receiving piece 6 for supporting the lower surface of the engaging piece 4 is provided at the center of the other separating end 3b in the width direction so as to project, and the locking claw 5 is provided on the upper surface of the base portion of the receiving piece 6.
An upward engaging claw 5b that engages with a in a radially detachable manner is formed. Further, a drainage ridge 7 is provided around the entire outer peripheral surface of the ring body 1 except the hinge portion 2 in the widthwise center thereof.

In the rain drain ring A thus constructed, the positions of the ring body 1 near the separating ends 3a, 3b are pressed from the outside so that the separating ends 3a, 3b are pressed.
The engaging claws 5a and 5b projecting from the tip end of are engaged with each other and are in a state of being coupled as shown in FIG. In order to open the ring body 1 thus annularly joined as shown in FIG. 2, the positions of the ring body 1 near the separating ends 3a and 3b are grasped by the fingers of the left hand and the finger of the right hand, respectively. When it is slid in the direction, one of the locking claws 5b is formed to have a width narrower than that of the other locking claw 5a, so that the engagement can be easily disengaged, and the separating ends 3a and 3b are outwardly moved from each other. When pulled, the left and right sides are expanded as shown in FIG.

Therefore, the rain catching ring A whose left and right sides are widened as described above is covered with the electric wire W as shown in FIG.
A and 5b can be engaged, and the rain ring A can be fixed to the electric wire W.

In this manner, a plurality of rain ring A is attached to an electric wire W stretched between electric poles P and P at appropriate intervals as shown in FIG. In the rain drain rings A thus mounted on the electric wires W, the rain water falling on the electric wires W between the adjacent rain drain rings A, A is slackened by the electric wires W of the rain drain rings A, A. Rain-driving ring A located at a low position
, And drops downward along the ridges 7 provided around the outer peripheral surface of the rain ring A. For this reason, the rainwater sprinkled on the electric wire W between the electric poles P, P is separated from each other at the positions between the plurality of rain cut rings A, A ... Installed, and the ridges 7 of the respective rain cut rings A are separated. Will be dispersed and dropped.

As shown in FIGS. 1 to 4, the rain ring A of the present invention is provided with a plurality of ridges 8 projecting in the transverse direction on the inner peripheral surface of the ring body 1 at substantially equal intervals. These ribs 8 adhere to the insulating coating layer on the surface of the electric wire W in a state where the rain cutting ring A is attached to the electric wire W, and the rain cutting ring A can strengthen the fixing to the electric wire A.

[0012]

As described above, the rain ring of the present invention can be used by mounting a plurality of electric wires stretched between electric poles at intervals with use of rainwater that has fallen onto the electric wires. Since it is possible to disperse and drip at the position of the attached rain drain ring, the amount of rain water dropped at one place is reduced. For this reason, it is possible to completely eliminate the problems that are conventionally found such as the formation of holes in the ground by raindrops, the damage to the roof by raindrops, and the generation of noise.
