Description

Technical Field

[0001] The invention belongs to the technical field of intelligent power supplies, and in particular relates to an intelligent power supply for powering monitoring equipment in metal and non-metal mines. Background Art

[0002] Metal and non-metal mines refer to all mining enterprises except coal mines, coal-based pyrite mines, coal-related and associated mines, and petroleum mines. Metal and non-metal mines include "six major systems" such as monitoring and surveillance system, underground personnel positioning system, emergency evacuation system, compressed air self-rescue system, water supply and rescue system, and communication system.

[0003] At present, most products on the market are mainly of several types: the first is a simple ACDC switching power supply. This solution has poor safety protection and no backup power, which can easily cause safety hazards to production; the second is to install a shell outside the ACDC switching power supply. This solution has no backup power and also has safety hazards; the third is to have backup power, but there is no input and output voltage and current monitoring function and self-operation status monitoring and detection supply, and no self-protection device is set.

[0004] Chinese utility model CN216649302U discloses a backup power supply for metal and non-metal mines, belonging to the field of backup power supplies. A backup power supply for metal and non-metal mines, including a power supply body, the power supply body is placed in a box, the bottom of the box is provided with a base, the power supply body is placed on the base; a circular arc plate is slidably connected in the box, the outer wall of the circular arc plate is provided with an air bag, the air bag is not full of air in the initial state, the circular arc plate and the air bag are both against the power supply body; a U-shaped rod is slidably connected to the outer wall of the box, one end of the U-shaped rod placed in the box is against the circular arc plate, a slide plate is slidably connected to the U-shaped rod, and an inflatable component is provided on the slide plate; the above scheme can protect the power supply body, prevent it from tipping over or exploding due to collision, and reduce the occurrence of safety hazards; however, this scheme cannot monitor the power supply operation status and environmental parameters, which is easy to cause safety hazards.
