Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, and more specifically, to a safety warning sign that can distinguish different maintenance tasks. Background Technology

[0002] Electrical signs, also known as electrical warning signs, are used to warn workers not to approach live parts or operate equipment to prevent sudden power restoration to de-energized equipment. The signs also indicate where workers can work and remind them of other safety precautions. "Do Not Close Switch, People Working" signs should be hung at work sites, on construction equipment, and on switches and knife switches that supply power to the work site or construction equipment once closed.

[0003] In existing technology, "Do Not Close Switch, People Working" signs are only available in a white background with red lettering, which cannot distinguish between mechanical and electrical work. Furthermore, multiple work permits may exist for the same equipment. Previously, due to the failure to verify work permit details after restoration work, accidents involving personal injury have occurred. Using signs of the same color and type makes it impossible to distinguish work permit types, easily leading to personnel misoperation and subsequent safety hazards. There is a lack of safe, durable, and distinguishable safety warning signs for different maintenance tasks. Additionally, a utility model patent with announcement number CN202976690U discloses a sign for electrical equipment maintenance, including a sign body and a rope for suspending the sign body on the electrical equipment, with a locking buckle on the rope; the sign body is made of insulating laminate; and a long strip magnet is located on the back of the sign body. This makes it difficult to distinguish between mechanical and electrical work, and its durability and practicality need improvement. Utility Model Content

[0004] To overcome the shortcomings of existing technologies where "Do Not Close Switch, People Working" signs are only white with red lettering, making it impossible to distinguish between mechanical and electrical work, and where multiple work permits may exist for the same equipment, resulting in personal injury accidents due to failure to verify work permit information during restoration efforts, and the lack of durable and safe safety warning signs that can differentiate between different maintenance tasks, this utility model provides a safety warning sign that can distinguish between different maintenance tasks. The sign includes a housing, a warning plate, and an identification plate. The warning plate is located in the center of the front of the housing, and an identification plate with a warning slogan is installed in the center of the warning plate. Red light zones are located on both sides of the identification plate, and yellow light zones are located above and below the identification plate.

[0005] Placing safety warning signs on electrical equipment allows for both textual and electrical warnings. When the mechanical side of the equipment is operating, the red lights on both sides of the sign illuminate as a reminder. When the electrical side is operating, the yellow lights above and below illuminate as a reminder. When both the mechanical and electrical sides are operating simultaneously, the red and yellow lights illuminate at the same time, making it easier for staff to distinguish between the two and preventing accidents caused by misoperation due to confusion. This significantly improves the practicality and safety warning effect of the signs.

[0006] Preferably, the connection between the warning board and the yellow and red light zones is made of transparent material, and the yellow and red light zones are respectively provided with yellow light sources and red light sources inside.

[0007] Preferably, a storage battery is installed inside the housing, and the storage battery is electrically connected to both the yellow light source and the red light source.

[0008] Preferably, a hanging plate is detachably mounted on the top of the back of the outer casing, the hanging plate is equipped with lifting lugs, and the bottom of the hanging plate extends downward to form a hanging groove between it and the outer casing.

[0009] Preferably, a warning light is installed in the middle of the top of the outer casing.

[0010] Preferably, heat dissipation grilles are installed on both sides of the outer casing, and a dustproof mesh is provided on the inner side of the heat dissipation grilles.

[0011] The ventilation grilles installed on the side wall of the safety warning sign's casing can dissipate heat, preventing overheating from prolonged illumination. Furthermore, the safety warning sign is easy to hang and secure, facilitating installation and removal by staff. Additionally, a single sign can serve multiple warning functions, avoiding the need for staff to hang excessive numbers of ordinary warning signs.

[0012] Preferably, the inner wall of the outer casing is provided with a high-temperature resistant coating, and the outer surface of the outer casing is equipped with a reinforcing plate.

[0013] Preferably, a control switch is installed on one side of the top of the housing, and the control switch is connected to the yellow light source and the red light source.

[0014] Preferably, a fixing back plate is installed in the middle of the back of the outer casing, and a plurality of threaded fixing holes are formed on the fixing back plate.

[0015] Preferably, the inner surface of the outer casing is provided with an insulating coating.

[0016] By applying an insulating coating, the insulation effect of the safety warning sign itself can be improved, thus preventing leakage and electric shock. Beneficial effects

[0017] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0018] (1) Place safety warning signs on electrical equipment. Warning signs can be displayed on signs with warning slogans. When the mechanical side of the electrical equipment is working, the red light zone on both sides of the warning sign can be turned on as a reminder. When the electrical side of the electrical equipment is working, the yellow light zone set above and below the warning sign can be turned on as a reminder. When the mechanical side and electrical side of the electrical equipment are working at the same time, the red light zone and the yellow light zone can be turned on at the same time, so that the staff can distinguish them. This avoids the staff from making mistakes due to inability to distinguish them, which leads to safety accidents. This greatly improves the practicality and safety warning effect of the warning signs.

[0019] (2) By setting the heat dissipation grid on the side wall of the safety warning sign, heat can be dissipated, avoiding overheating when the light is on for a long time. At the same time, the safety warning sign is easy to hang and fix, making it convenient for staff to install and remove. Moreover, one warning sign can serve multiple warning functions, avoiding the need for staff to hang too many ordinary warning signs.

[0020] (3) The high-temperature resistance can be improved by the high-temperature coating inside the warning sign shell, and the heat of the light can be used to prevent damage to the shell. The strength can be improved by the reinforcing plate outside the warning sign shell, making it less susceptible to damage from impact. Attached Figure Description
