Elevator standby power supply automatic switching structure

Abstract

The invention discloses an elevator standby power supply automatic switching structure which comprises an annular fixing block, a first conductive layer is embedded in an inner ring of the fixing block, the first conductive layer is electrically connected with a first power supply, and the first power supply is communicated with normal power supply equipment of an elevator. A second conductive layer of an annular structure is arranged on the portion, located outside the first conductive layer, of the fixing block, the second conductive layer is electrically connected with a second power supply, the second power supply is communicated with a standby power supply of the elevator, the inner ring portion of the fixing block is connected with a conductive block in a matched and abutting mode, and the conductive block is connected with a normal power supply circuit of the elevator. The bottom of the conductive block is fixedly connected with a spring, the bottom of the spring is fixedly connected with a bearing, and the inner ring part of the bearing is rotatably connected with a rotating shaft which is fixedly connected with the fixing block. The structure has the advantages that the function of power supply switching in an elevator can be automatically achieved, the connecting position is cleaned in real time in the switching process, and poor contact is avoided.

Description

technical field [0001] The invention relates to the technical field of safe use of elevators, in particular to an automatic switching structure of an elevator backup power supply. Background technique [0002] As a loading tool in high-rise buildings, the elevator has the advantages of quickness and convenience. However, when in use, problems often occur in the power supply equipment of the elevator, resulting in a power failure of the elevator. [0003] Since the elevator itself is a nearly closed metal shell, the internal signal is poor. When using it, especially at night when the power is cut off, the staff needs to switch the power supply for a long time, or open the door in an emergency, and the power inside the elevator is cut off. Afterwards, the increase of carbon dioxide concentration and the decrease of oxygen content will cause the stranded personnel to bear great psychological pressure, and when the standby circuit is used to switch, the circuit will be poorly co...
