摘要： An opening/closing device 1 includes a gate 10 that receives a flow of a sewage W, and can fall toward a downstream side of the flow, a fall prevention unit 20b that prevents the gate 10 from falling by supporting the gate 10, a support release unit 22b that releases the support for the gate 10 by the fall prevention unit 20b, a first float 18 that is arranged on the upstream side of the gate 10, and is smaller in specific gravity than the sewage W, a surfacing prevention unit 44 that prevents the first float 18 from surfacing, a second float 16 that is arranged on the upstream side of the gate 10, is arranged above the first float 18, and is smaller in specific gravity than the fluid, and a surfacing-prevention release unit 42 that releases, resulting from surfacing of the second float 16, the prevention of the surfacing of the first float 18 by the surfacing prevention unit 44. Further, the support release unit 22b is activated resulting from surfacing of the first float 18.

摘要： An opening/closing device 1 according to the present invention includes a gate 10 that receives a flow of a sewage W in an upright state, and can fall toward a downstream side of the flow and a first spring 52a that generates a force for bringing the gate 10 into an upright state, wherein the first spring 52 generates a force insufficient for bringing the gate 10 into the upright state if the gate 10 is in a fallen state, and generates a force sufficient for bringing the gate into the upright state if the gate 10 is tilted by an angle equal to or less than a predetermined angle.
摘要翻译： 根据本发明的开闭装置1包括：门10，其竖立状态地接收污水W的流动并且能够朝向流的下游侧下降;以及第一弹簧52a，其产生用于使污水W 门10处于直立状态，其中如果门10处于倒下状态，则第一弹簧52产生不足以使门10进入直立状态的力，并且如果门10处于直立状态，则产生足以使门进入直立状态的力 门10倾斜等于或小于预定角度的角度。
