Description

  TECHNICAL FIELD The present invention relates to a steel pipe tower drain groove cleaning device suitable for use in cleaning a drain groove of a slanted water disk attached to a hollow steel pipe tower such as a transmission line tower.

As shown in FIG. 5, the lower end portion of the transmission line tower 1 includes a main pillar material 2 made of a hollow steel pipe and two flange portions 4 on a bottom base material 3 attached to a concrete base (not shown). After connecting through the main pillar material 2, the main pillar material 2 is added.
Moreover, the transmission line tower 1 is often installed in a high altitude mountainous area, and is placed in a high humidity environment due to the influence of rainfall and fog, and the hollow portion of the main pillar 2 penetrates vertically. Therefore, a swash water disk 5 (drainage plate) is sandwiched between the two flange portions 4 at the bottom so that the dew condensation generated in the main column 2 is not accumulated inside.

  As shown in FIG. 6A, the swash water disk 5 has a disk shape, and the surface of the swash water disk 5 has an opening 5b (see FIG. And two drain grooves 5a having a cross shape (see FIG. 6B).

  Thus, since the opening 5b of the both ends of the draining groove 5a is formed in the outer peripheral surface of the oblique water board 5, insects, such as a bee and a ladybug, are inside the main pillar material 2 of the transmission line tower 1 from the opening 5b. In order to prevent the rust from being generated in the main pillar material 2 due to insect discharge by entering and overwintering or using as a cocoon, the spring 6 is opened as shown in FIG. 6B. In order to prevent the insects from entering the main pillar 2 by inserting it laterally and closing the opening 5b (see FIG. 10 of Patent Document 1 below).

JP 2007-89500 A

However, when removing the spring 6 from the opening 5b of the drain groove 5a during the patrol inspection of the transmission line tower 1, the worker uses the bare hand to hold the spring 6 inserted laterally with respect to the opening 5b. Since it cannot be removed, there was a problem that it was removed using a long-nose radio pliers.
In addition, after removing the spring 6, the worker pushes out dust collected in the draining groove 5a with a twig or a plucking wick and cleans the draining groove 5a. There is a problem that if dust or the like is pushed out 2-3 times, it will break, and the shape of the twigs and the core of the pampas grass is not necessarily suitable for insertion from the opening 5b of the drain groove 5a. The insertion has to be repeated many times, and there is a problem that it takes work time.

  An object of the present invention is to provide a steel pipe tower drainage cleaning device that can prevent insects from entering the hollow steel pipe tower and can easily perform the cleaning operation of the drainage groove of the slanting basin. .
