SLUICE GATE EQUIPPED WITH SEESAW FORM OF AUXILIARY COVER FOR WATERTIGHT

摘要

The present invention relates to a sluice gate equipped with a seesaw type watertight auxiliary cover to provide a sluice gate formed with a stable watertight structure between a gate frame and a gate leaf. According to the present invention, the sluice gate comprises: a gate frame comprising a frame body having an opening for allowing the fluid to flow, and a gate leaf guide formed on the frame body to stand upright on two sides of the opening; a gate leaf moving upwards and downwards on inner side of the gate leaf guide to open and close the opening; and a watertight auxiliary cover installed on the gate leaf guide in order to press and attach the gate leaf to the frame body by being hindered by the gate leaf and rotating while the gate leaf for closing the opening is lowered. The watertight auxiliary cover comprises: a seesaw type reaction member which is coupled to the gate leaf guide to face the gate leaf on the front side thereof and has a rotational structure by coupling a rotational coupling part formed by bending the left and right sides thereof to the gate leaf guide by a horizontal rotational axis; a first protruding member formed on the lower portion of the seesaw type reaction member to protrude toward the gate leaf to come in contact with the lower portion of the gate leaf while the gate leaf is lowered in order to pressurize the lower portion of the gate leaf; and an elastic member which connects the seesaw type reaction member to the frame body and elastically supports the seesaw type reaction member to make the lower portion of the seesaw type reaction member rotated toward the gate leaf around the rotational axis.
