DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to insulation of a high-voltage live line for applying an insulating paint to a high-voltage live line wired near an insulator in order to prevent a short circuit accident caused by a bird flying. It relates to a painting tool.

[0002]

2. Description of the Related Art A high-voltage power transmission line is supported through an insulator on a tower arm or the like. However, birds fly into the tower, making it easier to build nests. Birds sometimes fly in addition to conductive materials such as long crows as their nest material in their beaks. When such a conductive material comes into contact with a high-voltage transmission line that is a high-voltage live line, a short circuit accident occurs.

[0003] Conventionally, various measures against bird damage have been taken in high-voltage facilities such as high-voltage transmission line towers and substations. As a countermeasure against bird harm, for example, a bird guard is installed in a place where a short circuit may occur.

[0004]

However, birds often fly without fear of this and cause a short-circuit accident even if a bird-frog is installed. The effect was insufficient or incomplete.

Accordingly, an object of the present invention is to provide an insulating coating tool for a high-voltage live line for preventing a short circuit accident caused by bird damage.

[0006]

According to the present invention, there is provided an insulating coating tool for a high-voltage live line, comprising an operating rod and a coating unit provided at the tip of the operating rod and supplied with an insulating coating from a coating supply unit. An openable / closable case in which the unit is detachably fitted to a high-voltage live wire wired near the insulator, and a slit for securing the insulating paint supplied from the paint supply unit in the fitted state is secured. And a means for opening and closing the case is provided on the base end side of the operating rod, and a half case obtained by dividing the case into two is provided .
The half case in the closing direction
It has a resilient spring, and the opening and closing operation means,
Extends from the coating unit to the base end of the operation rod
By pulling this, the spring of the spring
Is the wire material that forcibly expands the half case against the force?
It consists of:

[0007]

In the above structure, if the case is fitted to the high-voltage live line and the operating rod is operated to move the case along the high-voltage live line, the insulating paint leaking from the slit is applied to the high-voltage live line. Therefore, even if a bird comes in contact with a high voltage live line and the like, a short circuit accident does not occur.

In FIG. 1, reference numeral 1 denotes an operating rod made of an insulating material such as a synthetic resin. A paint supply unit 2 is attached to the tip of the operation rod 1. The paint supply unit 2 and its operating means are the same as those described in Japanese Patent Application Laid-Open No. 9-155261, and the lever 3 is provided with a spool 4 provided on the base end 1a of the operating rod 1. When the operator pulls the wire 5 toward the user, the lever 3 rotates, and the insulating paint stored in the paint supply unit 2 is pushed out to the tube 6. It should be noted that other components can be applied as the paint supply unit.

A coating unit 10 is mounted on the tip of the operating rod 1 via a frame 9. 2 and 3
In the figure, reference numeral 11 denotes a drum-type case serving as a main body of the coating unit 10. The case 11 is formed by rotatably mounting a half case 12, 13 halved by a hinge portion 14.

Arms 15 and 16 extend from the half cases 12 and 13, respectively. The arm 15 and the arm 16 are rotatably mounted on a shaft by a pin 17 and are connected by a spring 18. The spring 18 rebounds the half cases 12 and 13 in the closing direction. One arm 1
A wire 19 extends from 6. As shown in FIG. 1, the wire 19 extends to the base end 1 a of the operation rod 1,
It is locked to. Note that nylon wires or the like are used as the wires 5 and 19.

Cover plates 12a and 13a are mounted on one end surfaces of the half cases 12 and 13 (FIGS. 3 and 4). A transmission line (high-voltage live line) 30 is provided at the center of the cover plates 12a and 13a.
Is formed with a circular hole 22 that fits into the hole. The inner diameter of the hole 22 is slightly larger than the outer diameter of the high-voltage live wire 30. Therefore, as shown in the solid line of FIG. 2 and FIG.
In the state where 2, 13 are closed and fitted to the high-voltage live line 30, a slight paint leakage slit t is secured between the high-voltage live line 30 and the high-voltage live line 30.

In FIG. 4, long holes 23 are formed in the cover plates 12a and 13a,
3 is detachably attached to the end face. Thereby, the mounting position of the lid members 12a, 13a to the half cases 12, 13 is finely adjusted according to the wiring curvature of the high-voltage live wire 30, and the case 11 is fitted to the high-voltage live wire 30, 11 can be smoothly moved along the high-voltage live line 30.

In FIG. 3, a bracket 25 extends from one end surface of the half cases 12 and 13. A roller 26 is axially mounted on the bracket 25. As shown in FIGS. 3 and 5, the high-voltage live line 30 is sandwiched between the rollers 26 from above and below, thereby preventing the case 11 from wobbling and guiding the case 11 to move smoothly along the high-voltage live line 30. I am trying to do it.

In FIG. 3, a container-shaped liquid receiver 28 is provided on the other end surface of the case 11 (an end surface on the rear side in the moving direction of the case 11). The insulating paint 29 of the paint supply unit 2 is supplied into the case 11 through the tube 6, leaks from the slit t, and is applied to the high-voltage live wire 30. Paint 2

The worker climbs the tower and holds the base 1a of the operating rod 1 in his hand. Then, by pulling the wire 19 forward, the half cases 12 and 13 are opened as shown by a chain line in FIG. Next, the half cases 12 and 13 are moved to the position where the high-voltage live wire 30 is sandwiched, and the wire 19 is loosened. Then, the half cases 12 and 13 are closed by the spring force of the spring 18, and the hole 22 is fitted into the high-voltage live line 30.

As described above, when the half cases 12, 13 are fitted to the high-voltage live wire 30, the other wire 5 (FIG. 1) is operated to apply the insulating paint 29 of the paint supply unit 2 to the case. 11 inside. At this time, the roller 26 holds the high-voltage live wire 30 as shown in FIG.

When the insulating paint 29 is supplied to the case 11, the operating rod 1 is operated in FIG.
Is moved in the direction of arrow A along the high-voltage live line 30, the insulating paint 29 in the case 11 leaks from the slit t and is applied to the high-voltage live line 30. At this time, since the insulating paint 29 that has fallen is collected in the liquid receiver 28, it does not fall to the ground and contaminate the ground. When the painting is completed, the wire case 19 is pulled back again to open the half cases 12 and 13 and removed from the high-voltage live wire 30.

As described above, according to this insulating coating tool,
The insulating paint can be easily applied to the high-voltage live line, and the painting operation can be performed safely even in the live state. In FIG. 6, reference numeral 33 denotes a crow that a bird has come flying and carried. In this way, even if the harness 33 is carried between the high-voltage live line 30 and the arm 31, the high-voltage live line 30
No short-circuit accidents occur because they are insulated. In addition,
The insulating coating tool of the present invention can be used not only in a steel tower but also in a substation or the like.
