Contactor type mechanical emergency starting device

Abstract

The invention discloses a contactor type mechanical emergency starting device, and the device comprises a bottom plate; a plurality of alternating current contactors are arranged on the bottom plate,and a shell covers each alternating current contactor; a driving device and a travel switch are arranged above the shell, and a linkage device is arranged below the shell; the linkage devices are driven by the driving devices to reciprocate up and down, the right lower portions of the linkage devices correspond to contacts of the alternating current contactor, the linkage devices make contact with the contacts when moving downwards and are far away from the contacts when moving upwards, and the driving devices are in linkage. The device is simple in structure and convenient to operate, operation of multiple devices in different states is achieved, the operation duration is greatly shortened, and precious time is saved for emergency situations.

Description

technical field [0001] The invention belongs to the field of mechanical emergency starting, and in particular relates to a contactor type mechanical emergency starting device. Background technique [0002] According to 11.0.12 of the "Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974-2014 (the fire pump control cabinet should be equipped with a manual mechanical pump to supply energy, and it should be ensured that when the control circuit in the control cabinet fails, there will be a management Authorized personnel start the fire pump in an emergency. Manually, it should work normally within 5 minutes of the alarm.) [0003] When the control circuit in the fire pump control cabinet breaks down and the fire pump cannot be started automatically, the immediate repair will meet the limitation of personnel quality and time. Fire alarm is also an emergency situation. This device can ensure the power supply Under normal conditions, no matter what the...

Problems solved by technology

[0004] The existing emergency start-stop device consists of a single or a group of start and stop buttons, which are used to start and stop the fire extinguishing system. When an emergency occurs, the separate stop buttons need to be operated one by one, and the operation time is long; the whole group of start-stop buttons It can only be started or stopped at the same time, and the state of all contactors must be consistent, so some equipment that does not have to be stopped or started must be stopped and started together, which brings a lot of inconvenience to actual use
