Charging and discharging locking mechanism for explosion-proof storage battery power supply device

Abstract

The invention discloses a charging and discharging locking mechanism for an explosion-proof storage battery power supply device. The charging and discharging locking mechanism comprises an explosion-proof switch box, a cable connector, a screw, a lead-in device, a connecting cable, a switch, an opening and closing handle and a plug position detector. When the plug and the socket of the cable connector are separated, a trip coil on the switch which is in a closed state in the explosion-proof switch box is triggered in advance through the detection of the plug position detector, so that the switch is tripped, the interior of the socket is not electrified when the explosion-proof combination state of the plug and the socket does not fail, and the environmental safety is guaranteed. Further, the safety of external operators is safeguarded. A locking mechanism is advanced in design, compact in structure, safe, stable and reliable, can adapt to different types of batteries, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of charging and discharging power supply devices, in particular to a charging and discharging locking mechanism for an explosion-proof storage battery power supply device. Background technique [0002] Explosion-proof trackless rubber-tyred vehicles powered by explosion-proof lead-acid batteries are mainly used in supporting after continuous mining and in the relocation and reverse operations of fully mechanized mining working faces, mainly including: battery scrapers, battery shovels, battery support trucks, etc. It has the advantages of high driving efficiency, green energy saving, simple maintenance and low operating cost. The explosion-proof batteries used in these vehicles require a quick-change structure to improve vehicle utilization. [0003] Traditional battery electric locomotives also use explosion-proof battery power supply units, but their input and output use pin connectors, which can only pre...

AI Technical Summary

Problems solved by technology

When the plug connector is separated, the inside of the plug connector on the battery side is always charged, which poses a safety hazard, especially after a long period of use, conductive dust and water mist accumulate on the inner wall of the female plug, which is prone to ground discharge

In addition, its anti-seismic performance cannot meet the requirements of explosion-proof trackless rubber-tyred vehicles powered by explosion-proof lead-acid batteries.
