Standby power for down-hole emergency refuge facility

Abstract

The invention discloses a standby power for a down-hole emergency refuge facility. The standby power utilizes a distributed structure and is composed of a main control standby power and a plurality of subordinate standby powers, and the main control standby power supply comprises a power explosion-proof tank and a LCD (liquid crystal display) module. The inside of the power explosion-proof tank is divided into a battery chamber, a wiring chamber, an electronic control chamber and a switch chamber, the inside of the battery chamber is provided with a battery module, and the inside of the electronic control chamber is provided with a control system. Every subordinate standby power consists of a power explosion-proof tank and a battery module of the subordinate standby power, every subordinate standby power can be in parallel connection with the battery module of the main control standby power, and is controlled by the main control standby power. The standby power for the down-hole emergency refuge facility can switch quickly to supply power for electric loads in the emergency refuge facility when an external power supply is interrupted after a mine accident happens, and has the advantages of being compact in structure, convenient to operate, quick in response, safe and reliable, having many output interfaces, and being wide in range of application and applicable to being used in mine coal down-hole emergency refuge facilities.

Description

technical field [0001] The invention relates to the field of underground emergency avoidance systems in coal mines, in particular to a large-capacity backup power supply for powering underground emergency avoidance facilities. Background technique [0002] my country is a large coal-producing country in the world. Due to the relatively backward operating equipment and technology, various mine accidents occur frequently, resulting in the number of deaths in coal mine accidents ranking first in the world. The underground emergency escape facility is a confined space that provides life support for those in distress who cannot evacuate in time when a disaster accident occurs underground, and is an important part of underground rescue. When the external power supply is interrupted after the mine accident, the backup power supply of the underground emergency escape facilities is responsible for providing power for the escape facilities and maintaining their continuous work, the im...
