Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention cleans insulators soiled by typhoons, soot, seasonal winds, etc., maintains the designed insulation strength, and prevents disasters due to soiling of the insulators. The present invention relates to an insulator washing machine for cleaning insulators used in electrical stations and power transmission lines in a live state.

(Prior Art) When insulators used in electrical stations, power transmission lines, etc. become contaminated by typhoons, soot, seasonal winds, etc., their insulation strength decreases, and if the strength falls below a predetermined value, a flashover accident occurs. For this reason, the applicant of this application
62-217814 proposes an insulator washer as shown in FIG. This insulator cleaning machine has a spray nozzle 7 at the tip of an operating rod 2 made of an insulating material.
In addition, a water tank 8 is provided between the operating portion 2a of the operating rod 2 and the injection nozzle 7, and the water tank 8 and the injection nozzle 7 are communicated through a water pipe 10, so that water from the compressed gas supply source is Air supply hose 4 for supplying compressed gas to the injection nozzle 7
has been established. Then, by opening the valve 11 provided on the operating part 2a side and injecting compressed air from the injection nozzle 7, the water in the water tank 8 is made into a mist and is injected 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 near the tip of the operating rod 2, so the operating section of the operating rod 2 When a worker holds the part 2a 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 poses a problem in that the cleaning work requires a great deal of effort. . 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 correction rod 31 made of an insulating material. Therefore, a new problem has arisen in that the insulator cleaning machine is very cumbersome.

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 rod during the insulator cleaning operation, thereby facilitating the insulator cleaning operation. The purpose of this invention is to provide an insulator cleaning machine that can be used to clean insulators.

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 the Problems) In order to achieve the first object, the present invention provides an injection nozzle at the tip of an operating rod made of an insulating material, and also provides an injection nozzle at the proximal end of the operating rod. In an insulator washing machine, the insulator cleaning machine is equipped with an operating section, and a means for rotatably connecting and supporting a pedestal made of an insulating material running on the surface of the insulator to a mounting section provided near the tip of the operating rod. It's getting better.

Moreover, in order to achieve the second object, the present invention
In addition to the structure of the invention, a measure is taken in which a weight for balance is provided at the proximal end of the operating rod, rather than at the supporting position.

(Function) In the first invention, when cleaning an insulator, first, the operating rod held at the support position on the base end side is tilted, and the pedestal near the tip of the operating rod is brought into contact with the surface of the insulator. let Then, the load of the operating rod, etc. acts on the surface of the insulator through the pedestal, and the entire load of the insulator washer is shared between the supporting position and the pedestal. When the operating rod is moved with the pedestal in contact with the surface of the insulator, the pedestal moves on the surface of the insulator, and the position of the injection nozzle is accordingly moved. In addition, since the pedestal is rotatably connected and supported to the mounting part, if you change the inclination angle of the operating rod while the pedestal is in contact with the surface of the insulator, the injection direction of the injection nozzle will change. The surface of the insulator is cleaned from all angles.

Further, in the second invention, since the weight is provided closer to the proximal end than the supporting position of the operating rod, in addition to the effect of the first invention, the operating rod can be moved with the operating portion of the operating rod lifted. Since the weight and the weight are balanced, it becomes easier to transport the insulator washer and move it on the insulator.

(Example) Hereinafter, an example embodying this invention will be described in the first to
Figure 6 will be explained.

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 (not shown) is connected for relative rotation.

As shown in FIGS. 1 and 2, a mounting tube 5 is connected to the distal end of the operating rod 2 so as to be perpendicular to the operating rod 2, and a movable mounting member 6 is connected to the distal end of the mounting tube 5. A spray nozzle 7 is attached. Further, at a position near the tip of the operating rod 2,
A front annular water tank 8 shown in FIG. 6 is fitted so as to be relatively rotatable (maximum angle is about 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 connected to each other by a flexible water pipe 10, and the water sent from the water tank 8 to the injection nozzle 7 passes through the air supply hose 4 and the inside of the operating rod 2 to the attachment pipe. The compressed gas sent to 5 is sucked and mixed by the ventilate effect of the injection nozzle 7, and is sprayed in the form of mist.

On the operation part 2a side of the operation rod 2, there is a valve 1 for supplying and shutting off air to the injection nozzle 7.
1 is provided. Further, a shoulder belt 12 is fixed to the operating portion 2a, and as shown in FIG. 1, a shoulder hanging point P is provided on the belt 12 as a supporting position when lifting the operating rod 2. .

At a position near the tip of the operating rod 2, there is a suspension insulator chain 14, which is connected in series with a suspension insulator 13 for a tension tower, to carry the load of the rod 2, water tank 8, etc.
A pedestal 15, which is a main part of the first invention and is made of an insulating material, is attached to the upper part of the holder. This pedestal 15 is connected to the suspension insulator 13 as shown in FIGS.
A pair of left and right brackets 1 are provided on the opposite side of the surface on which the contact protrusions 15a are provided.
5b are integrally erected. Then, with the mounting plate portion 16a as a mounting portion integrally formed on the outer circumferential surface of the mounting cylinder 16 fitted and fixed to the operating rod 2 engaged with the bracket 15b, the connecting pin 17 is held by the connecting pin 17. It is rotatably connected and supported as a fulcrum. By doing this, even if the inclination angle of the suspended insulator chain 14 is different or if the suspended insulator chain 14 is long and slack in the middle, the contact protrusion 15a of the pedestal 15 can be cleaned during the insulator cleaning operation. It becomes possible to change the injection direction of the injection nozzle 7 while keeping it in contact with the surface of the suspended insulator 13.

The reason why a large number of the contact protrusions 15a are formed is to ensure a sufficient creepage insulation distance when the pedestal 15 is placed in a bridge shape on the adjacent suspended insulator 13.

On the other hand, on the operating portion 2a side of the operating rod 2, a weight 1, which is a main part of the second invention, is located closer to the proximal end than the shoulder hanging point P, as shown in FIGS. 1 and 4.
8 is installed. This weight 18 is movable in the longitudinal direction of the operating rod 2 and is fitted onto the rod 2 and fixed to the mounting cylinder 20 by a bolt 19.
It is detachable and can be divided into multiple parts so that the weight can be changed.

The cleaning of the suspended insulator 13 by the insulator washer 1 configured as described above will be explained.

First, when the belt 12 is put on the shoulder, since the weight 18 is attached to the base end of the operating part 2a of the operating rod 2, the parts on the distal end side of the shoulder hanging point P, that is, the operating rod 2, the water tank 8 Since the combined load W1 of the pedestal 15, etc. (see Fig. 1) and the load W2 of the weight 18 located closer to the proximal end than the shoulder point P are almost balanced, the whole insulator cleaning machine can be easily cleaned. The injection nozzle 7 at the tip of the operating rod 2 can be transported to the desired location.
It can be easily placed on top of 3.

Further, the contact convex portion 1 formed on the lower surface of the pedestal 15
By sliding 5a 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.

Next, when the operating rod 2 is rotated to allow the injection nozzle 7 to enter between the adjacent suspended insulators 13 and the valve 11 of the operating section 2a is opened, compressed gas from the compressed gas supply source is supplied to the air supply hose 4. The compressed gas is supplied to the attachment pipe 5 through the operating rod 2, and the water in the water tank 8 is suction-mixed by the injection nozzle 7, and is sprayed from the injection nozzle 7. As a result, the inner surface of the suspended insulator 13 is cleaned. Ru.

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 1
3 is thoroughly cleaned.

After cleaning a certain suspension insulator 13, the operation rod 2 is operated to move to the next suspension insulator 13. At this time, the contact convex portion 15a of the pedestal 15 is slid on the surface of the suspension insulator 13. , it can be easily moved using only pressing force.

The above embodiment describes the cleaning work of suspended insulators among the insulators for power transmission line towers, but this work can also be applied to cleaning other insulators, such as long trunk insulators, insulator pipes used in electrical stations, support insulators, etc. The same is basically true for cases where

Moreover, this invention may be implemented as follows.

In the embodiment described above, the pedestal 15 is attached to the mounting plate portion 16a of the mounting cylinder 16 that is fitted and fixed to the operating rod 2, but it is also possible to provide a mounting portion on the side surface of the water tank 8 and mount the pedestal 15 thereto. .

Effects of the Invention As detailed above, the first invention allows the entire load of the insulator washer to be shared between the pedestal and the support position, and when the pedestal is run along the surface of the insulator, the injection nozzle The injection position of the nozzle can be easily moved, and its pedestal is rotatably connected to the mounting part from the tip of the operating rod, so tilting the operating rod changes the injection direction of the injection nozzle. can be easily changed, and the surface of the insulator can be quickly cleaned from all angles.

Moreover, the second invention has, in addition to the effects of the first invention,
Since the weight is provided closer to the proximal end than the supporting position of the operating rod, the load of the operating rod etc. and the weight are balanced, making it easier to move and transport the insulator washer on the insulator. There are excellent effects that can be achieved.
