AI Technical Summary

Technical Problem

Existing electric watertight dampers cannot be manually opened or closed when the motor fails, resulting in a single drive mode that cannot meet usage requirements.

Method used

A transmission gear and driven gear structure was designed, which, combined with a manual drive structure and a motor drive, realizes dual-mode drive. The manual drive structure enables manual opening and closing through a movable rod and a limit block, while the motor drive drives the gate to rotate through gears.

Benefits of technology

It enables manual opening and closing of the damper even in the event of a motor failure, ensuring the reliability and flexibility of the damper's operation and meeting the needs of various drive modes.

Abstract

The utility model relates to a dual-mode driving device of a ship electric watertight air brake, which belongs to the technical field of electric watertight air brakes and comprises an air brake frame and a first flashboard rotatably connected inside the air brake frame. And a manual driving structure capable of driving the first flashboard to rotate is arranged at the top of the air brake frame. According to the dual-mode driving device for the electric watertight air brake of the ship, by arranging a transmission gear and a driven gear, the transmission gear can drive the driven gear to rotate so as to enable a first gate plate to rotate, then by arranging a movable rod and a baffle, a movable plate can drive a limiting block to move upwards, and at the moment, the baffle can extrude a reset spring; and at the moment, a worker can conveniently and manually drive the rotating plate to rotate, so that the first gate plate can be manually driven, meanwhile, by arranging a driving motor, the dual-mode driving effect is achieved, and the operation condition of the whole watertight air brake is greatly guaranteed.
