WATER GATE OPENING AND CLOSING DEVICE
To provide a water gate opening and closing device that does not require a conventional counterweight.SOLUTION: In a water gate opening and closing device 10 having a cord-like member 12 that supports a gate body 11 on one side, and winding means 13 that rolls up one side of the cord-like member 12 to raise the gate body 11 that is located at the lowest position and closes the gate, thereby opening the gate, the cord-like member 12 has a hanging region that is continuous with the other end, where the other end is fixed and hangs down when the gate body 11 is located at the lowest position. The hanging region is provided with a weight portion 22 that has a weight per unit length greater than the other portions of the cord-like member 12. When the gate body 11 is located at the lowest position, the weight portion 22 is located on the opposite side to the other end of the cord-like member 12 based on the lowest part 35 that is located at the lowest position in the hanging region, with one end of the cord-like member 12 that is closer to the support position of the gate body 11 along the cord-like member 12.SELECTED DRAWING: Figure 1
【課題】従来のカウンターウエイトを不要とする水門開閉装置を提供する。【解決手段】一側で扉体１１を支持する索状物１２と、索状物１２の一側を巻き上げて、最下位置に配されて水門を閉じている扉体１１を上昇させ、水門を開く巻回手段１３とを有する水門開閉装置１０において、索状物１２は、他端部が固定され、扉体１１が最下位置に配された状態で垂れ下がる、他端部に連続した垂下領域を有し、垂下領域には、単位長さあたりの重量が索状物１２の他の部位より大きい重量部２２が設けられ、扉体１１が最下位置に配された状態で、重量部２２は、索状物１２に沿って索状物１２の扉体１１の支持位置に近い側の一端が、垂下領域において最も低い位置に配された最下部３５を基準にして索状物１２の他端部とは反対側に位置する。【選択図】図１
