Description

Technical Field

[0001] The present invention relates to the technical field of power production, and in particular to a voice prompt device for preventing accidental entry into outdoor cabinets for operation. Background Art

[0002] In power facilities, there are various boxes and cabinets. De-energized equipment and energized equipment are interlaced, and there may also be cross-operation among different specialties and teams in the same de-energized area. Different boxes and cabinets belong to different specialties and teams. Accidental entry into the cabinets for operation may lead to adverse consequences. For outdoor areas, at present, the reminder for preventing accidental entry into the interval is limited to reminding according to the spatial area, and there is an inaccurate situation.

[0003] Publication No. CN213024778U, a voice broadcast system for preventing wrong interval entry, relates to the early warning system field of power inspection equipment, and includes a main control room alarm and a main control room voice dialer arranged in the main control room, an infrared sensor and a door frame pressure sensor arranged in the protection screen cabinet in the protection room, and a logic processor, an indoor alarm and a voice dialer arranged in the protection room. The infrared sensors are respectively installed at the front cabinet door and the rear cabinet door of the protection screen cabinet. When it senses that the operation and maintenance personnel open the cabinet door of the protection screen cabinet, it sends a signal and transmits it to the input end of the logic processor for operation; the door frame pressure sensor is installed on the cabinet door handle of the protection screen cabinet. When the operation and maintenance personnel touch the cabinet door handle, the induction signal is transmitted to the input end of the logic processor for operation. When the operation and maintenance personnel select the protection screen cabinet to be inspected in this voice broadcast system before performing the inspection work, if they enter the wrong interval, the main control room alarm and the indoor alarm are activated for alarm, and the operation and maintenance personnel in the main control room can stop it in time through the main control room voice dialer.

[0004] Publication No. CN205563933U, a new type of alarm device for preventing accidental entry into the energized interval, belongs to the power technology field, and includes: a power supply, a power switch, a force-sensitive resistor, a signal reset button, a relay and a speaker; the power supply, the power switch, the force-sensitive resistor, the signal reset button, the relay and the speaker are connected in series to form an alarm circuit; the relay is connected in parallel with the force-sensitive resistor in a normally open contact manner; the power supply, the power switch, the force-sensitive resistor, the signal reset button, the relay and the speaker are all arranged in a metal shell, and a plurality of electromagnets are fixedly arranged on the bottom surface of the metal shell, and the electromagnets are used for adsorbing and connecting the alarm device to the cabinet door handle of the operation interval. When in use, the new type of alarm device for preventing accidental entry into the energized interval is adsorbed to the cabinet door handle of the operation interval through the electromagnet 1; when a person removes the alarm device and wants to enter the operation interval, the resistance value of the force-sensitive resistor will change, resulting in the conduction of the alarm circuit inside the alarm device, and the speaker 6 emits an alarm signal, causing the construction personnel and other nearby personnel to be alert and discover and stop this dangerous behavior in time.

[0005] In the above-mentioned prior art, the alarm device uses wired signal transmission and magnetic adsorption, which is limited to indoor equipment cabinets. However, for outdoor boxes and cabinets in power sites, the distribution gaps are large and the scope is wide. The cost of wired transmission is extremely high, and some boxes and cabinets are made of materials such as stainless steel and cannot be magnetically adsorbed, so it cannot be applied to outdoor boxes and cabinets. Summary of the Invention

[0006] To solve the above deficiencies, the present invention provides a voice prompt device for preventing unauthorized entry into outdoor boxes and cabinets, which is used to solve the problem of reminding unauthorized entry into outdoor boxes and cabinets and prevent unauthorized entry into interval operations.

[0007] To achieve the above and other related purposes, the present invention provides a voice prompt device for preventing unauthorized entry into outdoor boxes and cabinets, including: a photovoltaic power generation panel (1), a photosensitive switch (2), a voice broadcast module (3), and a power supply module (4); the photovoltaic power generation panel is installed outside the box and cabinet (5), and the photosensitive switch, voice broadcast module, and power supply module are installed inside the box and cabinet (5), and are connected by a power cord (6) inside and outside; the photovoltaic power generation panel receives sunlight to generate electricity and supplies power to the power supply module; the power supply module includes a rechargeable battery, which provides working power for the voice broadcast module; the photosensitive switch starts the voice broadcast module to work when receiving light; the voice broadcast module includes an audio storage and audio playback unit.

[0008] Preferably, the photovoltaic power generation panel is connected to the power supply module inside the box and cabinet through an insulated power cord, and can be inserted through the original holes (such as cable holes, ventilation holes, etc.) of the box and cabinet without affecting the original sealing performance.

[0009] Preferably, the audio file input of the voice broadcast module includes USB input and microphone input methods, which are convenient for importing from the computer terminal or inputting on-site recordings.
