Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an insulator cleaning device that cleans the lower surface of an insulator using an elastic rough surface body that has excellent conformability and adhesion to the surface shape of the lower surface of an insulator. This is what I did.

(Prior Art) A conventional cleaning device for insulators installed at power transmission line towers, power generation substations, etc. is a frame attached to the tip of an operating rod, as seen in Japanese Patent Publication No. 51-25595, for example. A brush was attached to the insulator, and cleaning was performed by sliding the brush against the surface of the insulator by operating an operating lever while injecting cleaning water toward the insulator. However, in this type of conventional brush, the grain of the brush is coarse, so that the bristles of the brush only come into point or line contact with the insulator surface, resulting in low cleaning efficiency. In addition, because insulators have the property of causing dimensional variations, deformation, and distortion during the manufacturing process, conventional brushes are unable to follow and adhere closely to the uneven lower surface shape of the insulator cap. There was a problem that the bottom surface could not be cleaned thoroughly. Furthermore, there were other problems such as the brush not being sufficiently durable, such as wear and tear of the brush in a relatively short period of time and hair loss.

(Objective of the Invention) An object of the present invention is to provide an insulator cleaning device that has excellent cleaning properties and durability for the uneven lower surface of an insulator umbrella.

(Summary of the Invention) The present invention replaces the conventional brush that makes only point or line contact with the insulator surface with a sliding contact portion that comes into sliding contact with the insulator surface to clean it, and which can be applied to the uneven insulator surface shape. An elastic rough surface material such as felt is used, which has excellent followability and can make surface contact with the insulator surface. The rough surface body is formed from a bulge portion which is elastically deformably attached to the elastic core material and fits into a recessed portion on the lower surface of the insulator umbrella, and a base portion which comes into sliding contact with the lower end surface of the insulator umbrella. With such a sliding contact part, it is possible to follow the shape of the uneven lower surface of the umbrella and ensure surface contact therewith, and operate the operating rod while injecting cleaning water toward the insulator. By doing so, the lower surface of the insulator can be sufficiently cleaned.

Embodiment 1 In FIG. 1, 1 is an operating rod made of an electrically insulated rod, and 2 is a cleaning section attached to the tip of the operating rod via hinges 3 and 4 so as to be rotatable vertically and horizontally. be. The cleaning section 2 is mainly composed of a frame 5 formed by bending wire, and components such as sliding contact sections 6, 6 and a water tank 7 are attached to this frame. The entire frame 5 is formed into a substantially U-shape, and is removably fitted to the insulator.
Nozzles 8 and 9 inject cleaning water supplied from the water tank 7 toward the insulator. 11 is a guide rod for fitting the cleaning part 2 to the insulator; 12, 13;
is a roller that rolls in contact with the insulator surface and guides the rotation of the cleaning section 2. The sliding contact part 6 is a coil spring 1
When the roll 15 hits the insulator, the sliding portion 6 rises against the spring force of the spring 14 and comes into close contact with the lower surface of the insulator. In the above configuration, the parts other than the sliding contact part 6 are well known. Next, details of the sliding contact portion 6 will be explained with reference to FIGS. 2 and 3.

The sliding contact portion 6 consists of a lower body portion 6a that slides on the lower surface of the umbrella portion 10A of the insulator 10, and an upper body portion 6b that slides on the upper surface of the umbrella portion 10A. 10B is insulator 1
It is a cap of 0. The lower body part 6a includes a base part 20 attached to the frame 5, and an elastic rough surface body 2, such as felt, attached to the upper surface of the base part 20.
It starts from 1. The rough surface body 21 is a ring-shaped core material 2 such as a silicon tube having sufficient elasticity.
The core material 22 is attached to the base portion 20 with a stopper 23. The rough surface body 21 is wound around the core material 22 with a wire 24, leaving both ends 21b. Therefore, the rough surface body 21 has a bulge part 21a which is elastically deformably attached to the core material 22, and a bulge part 21a attached to the core material 22 so as to be elastically deformable. 21b, that is, a base 21b, and the bulging part 21a follows the shape of the lower surface of the umbrella and fits into the recessed part a, and the base 21b abuts on the lower end surface b of the umbrella. The upper body part 6b is composed of a support plate 25 extending upwardly from the lower body part 6a, and a second elastic rough surface body 26 attached to the lower surface of the support plate 25. It comes into contact with the upper surface of the insulator shank 10A.

This cleaning device has the above-mentioned configuration, in which the operating rod 1 is held, the guide rods 11, 11 are brought into contact with the upper surface of the umbrella part 10A of the insulator 10 with the cap 10B in between, and the rollers 12, 13 are moved around the insulator umbrella. When pushed forward until it contacts the portion 10A, the roll 15 hits the edge of the bulk portion 10A, and the lower body portion 6a rises against the spring force of the spring 14 to form the bulge portion 21.
A is elastically deformed and fits into the recess a on the lower surface of the umbrella (see FIG. 3). Here, the rough surface body 21 not only has elasticity itself, but also is given sufficient elasticity by the core material 22, so that the bulging portion 21a of the rough surface body 21 is attached to the bulk portion 10 as shown in the figure.
Following the shape of the lower surface of A, it is elastically deformed into an elliptical shape and tightly adheres to the recessed part a. Also in that state,
The base portion 21b is in close contact with the lower end surface b of the umbrella. Moreover, since the grains of the rough surfaces 21 and 26 are fine, they can make sufficient surface contact with the surface of the umbrella. Therefore, by operating the operating rod 1 and rotating the sliding contact portion 6 back and forth along the insulator surface while injecting cleaning water from the nozzles 8 and 9, the entire surface of the insulator bulk portion 10A can be sufficiently cleaned.

Embodiment 2 In FIG. 4, a rough surface body 31 consists of a bulging portion 31b wound around a core material 22 and a base portion 31a disposed in a groove portion of a base material 20. As shown in FIG. Both parts 31
Although a and 31b are separate bodies, they are in close contact with the recessed portion a and the lower end surface b, respectively, and have the same effects as those of the first embodiment.

(Effects of the Invention) As explained above, in the insulator cleaning device according to the present invention, the sliding contact portion 6 that comes into sliding contact with the insulator bulk portion 10A is formed of the elastic rough surface body 21 instead of the conventional brush. It can come into surface contact with the surface of the umbrella to thoroughly clean it, and it also has excellent durability. In addition, since the sliding contact portion 6 is formed of a bulge portion 21a that elastically deforms and fits into the recessed portion a on the lower surface of the umbrella, and a base portion 21b that contacts the lower end surface b of the umbrella, the uneven portion of the umbrella portion is formed. It can follow the surface shape of the lower surface, reliably adhere to it, and thoroughly clean it.
