Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention cleans insulators that have been contaminated by typhoons, soot, seasonal winds, etc., maintains the designed insulation strength, and prevents disasters caused by soiling of the insulators. Related to insulator cleaning machines to prevent
This invention relates to an insulator cleaning machine for cleaning insulators being used on power transmission lines while the lines are live.

(Prior Art) Insulators in use at electrical stations, power transmission lines, etc. are contaminated by typhoons, soot, seasonal winds, etc., resulting in a decrease in insulation strength, leading to floodover accidents. For this reason, the applicant of the present application
In Japanese Patent No. 217814, an insulator washer as shown in FIG. 7 is proposed.

This insulator washer is provided with a spray nozzle 7 at the tip of an operating rod 2 made of an insulating material, and a water tank 8 is provided between the operating portion 2a of the operating rod 2 and the spray nozzle 7. An air supply hose 4 is provided which communicates with the injection nozzle 7 through a water pipe 10 and supplies compressed gas from a compressed gas supply source to the injection nozzle 7. Then, the valve 11 provided on the operation part 2a side is opened to inject compressed air from the injection nozzle 7 to the water tank 8.
By spraying the water inside into a mist onto the inner surface of the suspended insulator 13, the soiled surface of the insulator is cleaned.

(Problems to be Solved by the Invention) However, in the above conventional insulator washer, there was no member supported by the suspended insulator 13 on the lower surface of the water tank 8 and at the tip of the tip 2. When a worker holds the operating part 2a of the operating rod 2 and cleans the suspended insulator, the entire load of the water tank 8 and the operating rod 2 is applied to the operator of the operating part 2a, which requires a lot of effort for the cleaning work. There was a problem that it required In order to solve this problem, it was necessary for another worker to lift the tip of the operating rod 2 from above using a separately provided auxiliary rod 31 made of an insulating material.

Therefore, a new problem has arisen in that the insulator cleaning work is extremely troublesome.

The first object of the present invention is to enable the insulator cleaning machine to be easily moved on the insulator, and to reduce the load acting on the operating section of the operating lower F during the insulator cleaning operation, thereby facilitating the insulator cleaning operation. An object of the present invention is to provide an insulator cleaning machine that can be easily cleaned.

In addition to the first object, a second object of the present invention is to provide an insulator cleaning machine that is easier to transport and move on the insulator.

Structure of the Invention (Means for Solving Problems) In order to achieve the first object, the present invention provides a spray nozzle at the tip of an operating rod made of an insulating material, and also includes a spray nozzle between the operating portion of the operating rod and the spray nozzle. A water tank is provided between the insulator and the insulator, the water tank and the injection nozzle are connected through a water pipe, and an air supply hose is provided for supplying compressed gas from a compressed gas supply source to the injection nozzle. In the washing machine, a pedestal made of an insulating material running on the upper surface of the insulator is provided at the tip of the operating rod or the lower surface of the water tank.

Further, in order to achieve the second object, the present invention takes a measure of providing a weight for balance at the base end of the operating rod in addition to the configuration of the first invention.

(Function) In the first invention, since a pedestal made of an insulating material is provided at the tip of the operating rod or the bottom surface of the water tank, the pedestal can be placed on the top surface of the insulator to perform cleaning work on the insulator. As a result, the load of the water tank and the operating rod does not act so much on the operating section of the operating rod, making it possible to easily perform the insulator cleaning work.

Further, in the second invention, since a weight is provided at the base end of the operating rod, in addition to the effect of the first invention, the operation rod and the water tank can be operated with the operating portion of the operating rod lifted. Since the load and the weight are balanced, it becomes easier to transport the insulator washer and move it on the insulator.

(Example) An example embodying the present invention will be described below with reference to FIGS. 1 to 6.

In FIG. 1, reference numeral 1 indicates the entire insulator cleaning machine of the present invention, and a compressed gas supply installed on the ground via a joint 3 is connected to the base end of an operating rod 2 made of an insulated pipe constituting the cleaning machine 1. A flexible air supply hose 4 connected to a source (path shown) is connected so as to be relatively rotatable.

As shown in Fig. 1.2, a mounting pipe 5 is connected to the tip of the working port/throat 2 so as to be perpendicular to the operating rod 2, and a movable mounting member is connected to the tip of the mounting pipe 5. An injection nozzle 7 is attached via 6.

Further, a front annular water tank 8 shown in FIG. 6 is fitted in a position near the tip of the operating rod 2 so as to be relatively rotatable (maximum angle is approximately 20 degrees). At the top of the water tank 8, there is provided an air intake pipe 9 which also serves as a water supply port and is equipped with a check valve (not shown).

The water tank 8 and the injection nozzle 7 are formed by a flexible water pipe 10.
The water sent from the water tank 8 to the injection nozzle 7 is sucked by the venturi effect of the injection nozzle 7 by the compressed gas sent to the attachment pipe 5 through the air supply hose 4 and the inside of the operating rod 2. It is mixed and sprayed as a mist.

A valve 11 for supplying and shutting off air to the injection nozzle 7 is provided on the operating portion 2a side of the operating rod 2. Further, a shoulder strap 12 is fixed to the operating portion 2a.

At a position near the tip of the operating rod 2, there is an insulator for supporting the load of the rod 2, water tank 8, etc. on the upper part of a suspension insulator chain 14 formed by connecting suspension insulators 13 for a tension tower in series. A pedestal 15, which is a main part of the first invention and is made of material, is attached. As shown in FIGS. 2 and 3, this pedestal 15 is provided with a plurality of contact convex portions 15a arranged in two rows at a predetermined interval for contacting the upper surface of the suspension insulator 13, and a pair of left and right brackets 15b are integrated on the upper surface. It is erected. Then, the mounting plate portion 16a integrally formed on the lower surface of the mounting cylinder 16 fitted and fixed to the operating rod 2 is connected to the bracket 15b so as to be relatively rotatable in the vertical direction using the connecting pin 17. ing. By doing this, when the inclination angle of the suspended insulator chain 14 is different, or when the suspension insulator chain 14
Even if the suspension is long and slack in the middle, the lower surface of the pedestal 15 can be moved to follow the upper surface of the suspended insulator chain 14 during the insulator cleaning operation.

The reason why a large number of the contact protrusions 15a are formed is that the pedestal 15 is connected to the adjacent suspension insulator 13 in a bridge shape! ! This is to ensure sufficient creepage insulation distance when installed.

On the other hand, as shown in FIGS. 1 and 4, a weight 18, which is a main part of the second invention, is attached to the operating portion 2a side of the operating rod 2. As shown in FIGS. This weight 18 is fitted onto the rod 2 so as to be movable in the front-rear direction, and is attached to the cylindrical body 20 which is fixed by a bolt 19, and is divided into a plurality of parts so as to be removable and changeable in weight. has been done.

First, when the bell) 12 is hung on the shoulder, since the weight 18 is attached to the base end of the operating part 2a of the operating rod 2, the shoulder rest is attached to the members in front of the point P, that is, the operating rod 2, the water tank 8 Since the combined load Wl of the cradle 15, etc. (see Fig. 1) and the load W2 of the weight 18, which is located behind the point P on the shoulder rest, are almost balanced, the entire insulator washing machine can be easily cleaned. It can be transported to a target location, and the injection nozzle 7 at the tip of the operating rod 2 can be easily placed on the target suspension insulator 13.

Further, by sliding the contact convex portion 15a formed on the lower surface of the pedestal 15 in contact with the upper surface of the suspension insulator 13, the injection nozzle 7 can be easily moved to the target suspension insulator 13 using only pressing force. can.

Next, rotate the operating rod 2 to remove the adjacent suspension insulator 1.
3, enter the injection nozzle 7 between the valves 1 and 1 of the operating section 2a.
When the compressed gas (Jl; The mixture is mixed by suction and sprayed from the injection nozzle 7, and as a result, the inner surface of the suspended insulator 13 is cleaned.

The operator rotates the operating part 2a of the operating rod 2 in the direction of the arrow as shown in FIG. The suspended insulator 13 is cleaned thoroughly.

After cleaning a certain suspension insulator 13, operate the operating rod 2 and proceed to the next step 9. When moving to the tatami mat 13, by sliding the F side of the pedestal 15 on the top surface of the insulator 13, the tatami mat 13 can be easily moved using only pressing force.

The above Example C describes the cleaning work of the ゛U insulator among the insulators for power transmission line towers.
For example, the same principle applies when cleaning long insulators, insulator pipes used in electrical stations, support insulators, and the like.

Moreover, this invention may be implemented as follows.

In the embodiment described above, the pedestal 15 was attached to the tip of the operating rod 2, but this should be attached to the F side of the water tank 8.

Although not directly related to the present invention, even if the pedestal 15 is omitted and only the weight 18 is used, the insulator cleaning machine can be easily moved.
