LED sound-light alarm device

Abstract

The invention discloses an LED sound-light alarm device, and belongs to the technical field of power safety protection. A solved technical problem is to provide the LED sound-light alarm device which can protect an electric power worker working in a dangerous region from electric shock. An employed technical scheme is that the device comprises an LED lampshade; the bottom of the LED lampshade is connected with a pedestal; the LED lampshade comprises an outer housing, an inner housing, and a reflecting cover; the outer wall of the pedestal is provided with a power input connector and a power switch; the interior of the pedestal is provided with a sound-light alarm circuit board; the outer wall of the top of the pedestal is provided with an LED light-emitting lamp board; the top of the inner housing is provided with an induction chip and a loudspeaker; the sound-light alarm circuit board comprises a power circuit, a control circuit, a boost circuit, a voice alarm circuit, and a power input terminal A1; and the device is suitable for the power field.

Description

technical field [0001] The LED sound and light alarm device of the invention belongs to the technical field of electric power safety protection. Background technique [0002] In the power system, when an equipment maintenance is carried out in the substation room, the operating equipment adjacent to the equipment that needs to be overhauled is usually in a charged state. This type of live operating equipment is called a "dangerous point" in the safety production of the power system; Maintenance workers enter the area by mistake, board or touch live equipment by mistake, causing personal and equipment accidents. On the barriers or fences between the operating equipment on both sides of the workplace and on the opposite side, as well as on the barriers or fences of the aisle that prohibits passage, hang the "stop, high voltage danger" sign to warn maintenance workers not to enter the electrified area or approach the dangerous point However, in the actual work process, due to ...

Problems solved by technology

[0002] In the power system, when an equipment maintenance is carried out in the substation room, the operating equipment adjacent to the equipment that needs to be overhauled is usually in a charged state. This type of live operating equipment is called a "dangerous point" in the safety production of the power system; Maintenance operators mistakenly enter the area, mistakenly log on or touch live equipment, causing personal and equipment accidents. On the barriers or fences between the operating equipment on both sides of the workplace and on the opposite side, as well as on the barriers or fences of the aisles that prohibit passage, hang "stop, high voltage danger" signs to warn maintenance workers not to enter live areas or approach dangerous points However, in the actual work process, due to factors such as lack of concentration, work fatigue, and carelessness, it is easy for maintenance operators to enter live areas by mistake, approach dangerous points, and cause personal injury accidents by mistakenly boarding or touching live equipment, threatening The life safety of maintenance workers

[0003] Although the "stop, high voltage danger" signboard can clearly distinguish the working area and the live area, the flat text format is not noticeable in an environment with a lot of equipment, miscellaneous personnel, and loud maintenance tools and appliances; therefore, for more LED sound and light alarm device is particularly important to effectively warn that the live area is a dangerous point
