PURPOSE: A safety device against overturning a pneumatic type movable weir installed on a breakwater, a river bank and a road is provided to stably guarantee the rotator motion of a movable panel by preventing a movable panel from overturning when water flows backwards due to a difference between high and low water. CONSTITUTION: A safety device against overturning a pneumatic type movable weir installed on a breakwater, a river bank and a road comprises a fixed plate(31), multiple projecting bars(32) and a projecting height adjustment bolt(33). The fixing plate is installed on the upper side of an anchorage zone(12) with an airbag(10) installed and inserted into an anchor bolt(2). The multiple projecting bars are installed with the same gap from each other on the upper side of the fixing plate, and protruded to be sloped towards an elastic hinge(13). The height adjustment bolt is combined with a screw to the inside of the projection bar and adjusts the height of the projection. |
