Description

[Detailed description of the invention] (Field of industrial application) This invention is designed to prevent erroneous contact with adjacent areas and illusions when working in a vertically long area where relays, switches, etc. of a predetermined substation system are arranged on a switchboard. It also relates to accident prevention devices such as switchboards that prevent accidents caused by misidentification.

(Prior art) A single vertical area with approximately the same width is used as the area where relays, switches, etc. of a specified substation system are installed,
In a switchboard made up of a plurality of these single vertically long areas connected horizontally, when working on a specific single vertically long area, the adjacent single vertically long areas on both sides of that specific single vertically long area will be marked with a red frame. Transparent vinyl sheets were installed to prevent accidents caused by accidental contact with adjacent areas, illusions, and misunderstandings.

(Problem that the invention aims to solve) Every time a specific single vertically long area is worked, a transparent vinyl sheet with a red frame is stretched over the adjacent single vertically long area, which is difficult to stop and remove when expanding. There was a problem in that it required a lot of time and was extremely troublesome.

(Means for solving the problem) The present invention is such that a holding member equipped with a transparent sheet with a danger display frame is movably attached to a guide rail provided at the upper end of a switchboard, and when working in a single vertically long area as required. The holding member can be displaced to an adjacent single vertically long area, and the transparent sheet with a danger display frame can be immediately pulled downward to cover the adjacent single vertically long area, and the horizontal width is approximately the same. The switchboard is made up of multiple horizontally connected single vertical sections, with a full-width guide rail installed at the top end of the switchboard, which can be pulled out downwards and stopped at the bottom end at a predetermined position, and comes with a danger display frame that can be rolled up. The present invention provides an accident prevention device for a switchboard, etc., in which a holding member made of a transparent sheet is attached to the guide rail so as to be freely displaceable in the longitudinal direction.

(Function) By displacing the holding member along the guide rail, the transparent sheet with the danger display frame can be immediately drawn downward to cover an adjacent single longitudinal area.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the switchboard 1 in the device of the present invention consists of a single vertical area 2 ₁ , 2 ₂ , approximately the same width, in which relays, switches, meters, etc. of each substation system are arranged vertically. 2 ₃ , 2 ₄ . . . are arranged in series in the horizontal direction.

A downward opening 3a is provided at the upper end of the switchboard 1C
A guide rail 3 consisting of a shaped cross-sectional member and spanning almost the entire width.
will be established.

Next, as shown in FIGS. 1 and 3, a transparent sheet 6 with a danger display frame 6 having a danger display frame section 6a such as a red frame is wrapped around the winding shaft 5 whose both ends are supported on the bracket 4, and the sheet is pulled out downward. A holding member 7 whose lower end can be stopped at a predetermined position and can be wound up is provided. It is slidably fitted into the guide path 3b, and in this case, two such holding members 7 are attached to the guide rail 3.

Therefore, the holding members 7, 7 are moved along the guide path 3b of the guide rail 3 via the headed frame 8, and are freely displaceable.

In the figure, 9 is a guide rail mounting bracket, 10 is a weight bar, 11 is a tension string, 12 is a relay, 1
3 is a switch, 14 is a meter, and 15 is a stop provided at the lower end of each single longitudinal section.

Since the device of the present invention is constructed as described above, the fourth
Referring to the figure, when working on a predetermined single vertical area 2 ₃ in the switchboard 1, this single vertical area 2 ₃
The holding members 7 and 7 are moved and displaced along the guide rail 3 in the single vertically long areas 2 ₂ and 2 ₄ adjacent to each other, and the respective tension strings 11 are immediately pulled to lower the transparent sheet with the danger display frame. Pull out 6,
A tension string 11 is tied to the stopper 15, and the single longitudinal area 2 ₂ , 2 ₄ on both adjacent sides is covered by the transparent sheet 6 with a danger indicator frame.

In this way, when working in the single vertically long area 2 ₃ , since the adjacent single vertically long areas 2 ₂ and 2 ₄ are covered by the transparent sheet 6 with the danger display frame, the operator may accidentally Relays of single elongated area 2 ₂ , 2 ₄ ,
It does not come into contact with switches etc.

After the work is completed, when the tension string 11 is released, the transparent sheet 6 with the danger display frame is automatically wound around the winding shaft 5.

Although this embodiment is applied to a power distribution board, the present invention can also be applied to a power substation device or the like in which single longitudinal sections of approximately the same width are arranged in series in the horizontal direction.

(Effect of the invention) The present invention allows the operator to move and displace the holding member along the guide rail and immediately pull down the transparent sheet with the danger display frame to cover a single longitudinal area adjacent to the work area. Not only can it prevent accidents, but it can also prevent equipment damage and destruction accidents, and its practical effects are great.
