Description

Electric air-break warning sign board

Technical Field

The utility model relates to a signboard, in particular to an electric air-break warning signboard.

Background

The low-voltage AC/DC small-sized idle switch is widely applied to a power system, when the corresponding load is required to be overhauled, the corresponding small-sized idle switch is disconnected firstly according to the requirements of electric power industry safety working regulations, and a sign board for prohibiting switching on and working by people is arranged on the body of the switch. The hanging nameplate is an important technical measure for ensuring safety in the power industry, so that the switch is prevented from being turned on by mistake to send electricity to a maintenance site, and the safety of operators or equipment is threatened.

Because the small-sized idle opening has smaller volume, the sign board is not convenient to install on the small-sized idle opening, at present, the method adopted by each factory station mainly winds the hanging rope for hanging the sign board on the small-sized idle opening operating handle or the opening and closing state indicator lamp thereof, and because the small-sized idle opening operating handle has extremely small volume and smoother surface, the hanging rope of the sign board is not easy to wind, and the sign board is easy to fall off, and does not meet the requirements of safety measures. The length of each sign hanging rope is different, so that the heights and directions of the sign hanging ropes are uneven, and especially the space in the cabinet is more, when the sign hanging ropes are arranged together in a row in a concentrated mode, when a plurality of switches are required to be simultaneously provided with the sign, the sites are extremely messy, and harm is caused to human bodies or equipment in severe cases.

The nameplate unit and the base are both made of PVC materials.

The utility model discloses an electric air-break warning sign board, which has the following technical effects:

1) The first splicing block and the second splicing block are adopted for splicing, the nameplate can be installed rapidly, the nameplate shields the idle opening operation handle, the idle opening can not be closed, and the mechanical error prevention function is achieved. When later-stage needs to be taken down, can directly pull out the sign, and is simple and convenient.

2) The device can be matched with the empty openings of different models, the lower ends of the identification plates are clamped with the second splicing blocks with corresponding numbers through the first splicing blocks, the warning plates at the empty openings of different models are tidy and attractive, and the warning plates can be flexibly adjusted according to the needs.

In the figure: the novel multifunctional portable electronic device comprises a nameplate unit 1, a base 2, an empty opening 3, a cabinet inner side plate 4, a warning sign 5, a graphic sign 6, a nameplate 1.1, a first splicing block 1.2, a bulge 1.3, a second splicing block 1.4 and a clamping groove 1.5.

Detailed Description

As shown in fig. 1 and 6, an electric air-break warning sign board is formed by processing a PVC material. The device comprises a plurality of nameplate units 1 and a base 2. The plurality of sign units 1 are mounted side by side on the base 2 and match the width of the space 3 in the width direction (the width of the mounted sign shielding surface is equal to or slightly larger than the width of the space). Namely, when the air gap 3 is single-phase, the width of the shielding surface of the signboard is consistent with the width of the single-phase air gap; when the space opening 3 is two-phase, the width of the shielding surface of the signboard is consistent with the width of the two-phase space opening; when the air gap 3 is three-phase, the width of the shielding surface of the signboard is consistent with the width of the three-phase air gap. The base 2 is fixed on the inner side plate 4 of the tray cabinet through screws or strong magnets and is positioned below the air switch 3, so that the stability of the device is ensured.

As shown in fig. 2-5, the sign unit 1 includes a sign 1.1, where the thickness of the sign 1.1 is 1.5mm, and the front surface of the sign 1.1 is printed with a "closing prohibition" and a "manual" warning sign 5 (white background red character) and a graphic sign 6.

The back of the lower end of the signboard 1.1 is integrally formed with a first splicing block 1.2, four groups of bulges 1.3 are arranged at the rear end of the first splicing block 1.2, one end of a second splicing block 1.4 is tightly spliced with the bulges 1.3 on the first splicing block 1.2 through a clamping groove 1.5, and the other end of the second splicing block 1.4 is tightly spliced with the clamping groove 1.5 on the base 2 through the bulges 1.3.

Preferably, strong magnet adsorption layers are sprayed on the outer side wall of the bulge 1.3 or the inner side wall of the clamping groove 1.5, so that the adsorption reliability is ensured.

The dimensions of the first and second tiles 1.2, 1.4 may be 16 mm by mm (length by width by height), and the overall length of the sign 1.1 and first tile 1.2 is 80mm.

Working principle and process: based on the great available space in the switch board cabinet, install base 2 in sky division 3 below level, joint second splice 1.4 on the base 2, second splice 1.4 can be by a plurality of constitutions, the level is arranged to the empty division 3 of adaptation not unidimensional cabinet body and different forms, quantity arrangement. After the opening 3 has been opened, a corresponding number of first tiles 1.2 are mounted on the second tiles 1.4. The front of the nameplate 1.1 just shields the idle opening operation handle so as to ensure that the idle opening 3 cannot be closed again under the condition that the device is not dismantled, thereby ensuring the safety of maintenance personnel and equipment. When the device is required to be dismantled in the later stage, only the signboard 1.1 with the first splicing block 1.2 is required to be taken down.
