the invention relates to a gear driving system of a sector rotary gate, belonging to the field of medical treatment.

background

At present, the gate is opened and closed mainly by two modes, namely winch opening and closing and hydraulic press opening and closing. Because the sector rotary gate is not applicable to a hoisting opening and closing mode due to a special working mode, the main opening and closing mode of the sector rotary gate at present is that a hydraulic machine is matched with a connecting rod mechanism to open and close, such as a Thames river tidal gate.
