The invention relates to a flushing gate structure, in particular to a structure for opening and closing a flushing gate in a manner that a gate board is controlled to rotate by an eccentric center shaft. The flushing gate structure comprises the gate board, a substrate, connecting plates, rocker arms, a rotation center shaft, sliding rails and swing cylinders, wherein the gate board is connected with the bilaterally symmetrical connecting plates; each connecting plate is rigidly connected with the corresponding rocker arm; lower ends of the rocker arms are fixedly arranged on the rotation center shaft; each rocker arm is provided with the corresponding sliding rail; the rotation center shaft is located at the back side of the gate board, and fixedly arranged on the wall of the outer side of the substrate; the axis of the rotation center shaft is located at the middle part of the gate board; a piston rod of each swing cylinder is hinged to the corresponding sliding rail; the other ends of the swing cylinders are hinged to the substrate; when the gate board is closed, the end, contacted with the corresponding sliding rail, of each piston rod is located at the upper part of each rocker arm. The flushing gate with the structure is simple in structure, convenient to open and close, not limited by regions, capable of saving water resources, convenient for dredging pipelines and capable of saving manpower and material resources.
Description
technical field [0001] The invention relates to a flushing door structure, in particular to a structure for opening and closing the flushing door by controlling the rotation of a door panel through an eccentric axis. Background technique [0002] With the continuous development of the water net box culvert system, the box culvert is often blocked by the deposited sludge or sundries. Generally, manual dredging is adopted, which is not safe and labor-intensive. [0003] The Chinese utility model patent application with the patent application number 201320143942.6 titled an environmentally friendly and energy-saving flap flushing door discloses a flushing door structure that controls the flushing door switch through a transmission shaft, a support arm and a driving device. The mechanism flushing door is practical , Easy to open and close, not subject to geographical restrictions. However, the structure is too complicated, the opening and closing speed is slow, and the effect o...
