PROBLEM TO BE SOLVED: To provide a movable weir capable of preventing the occurrence of a water drop, and capable of relieving an upstream side water level variation by a flow rate variation, by automatically adjusting opening of a weir body, while holding an upstream side water level by resistance of a weir body of a submerged weir type.SOLUTION: The movable weir is interposed in a water passage, and includes at least the weir body and a set of support links for forming an acute angle to the horizontal direction and having mutually the equal length in parallel. One end of the set of support links is respectively joined by a hinge to the weir body, and the other end of the set of the support links is respectively joined by a hinge to an immovable point.
【課題】潜り堰型の堰本体の抵抗によって上流側の水位を保持しつつ、堰本体の開度を自動的に調整することで、落水の発生を防止し且つ流量変動による上流側の水位変動を緩和することが可能な可動堰を提供する。【解決手段】水路に介設する可動堰であって、堰本体と、水平方向に対して鋭角をなし、互いに平行且つ等長な一組の支持リンクと、を少なくとも含み、前記一組の支持リンクの一端は、前記堰本体にそれぞれヒンジ結合し、前記一組の支持リンクの他端は、不動点にそれぞれヒンジ結合する。【選択図】図１
