PROBLEM TO BE SOLVED: To provide a water level adjustment device, for operating only by a mechanical mechanism, installable in anyplace of a paddy field, also reducing the number of part items, being compact, and capable of adjusting a water level of the paddy field in a constant range.SOLUTION: A water level adjustment device comprises a water intake port for communicating with the irrigation channel side, a casing having a water supply port for communicating with the paddy field side, a float movably provided in the substantially vertical direction inside the water supply port side of the casing and a valve installed on a first rotary shaft provided in an upper end part of a horizontal part of the water supply port and is constituted so as to open the water intake port when the valve rotates to the irrigation channel side in response to a descent of the float. The connection of the float and the valve is executed by a second rotary shaft provided in a holding member installed on the substantially upper end of a shaft extending above the substantial center of the float and a rod-like member having both ends rotatably installed on a third rotary shaft installed on an opposite side surface of the water intake port side of the valve.
【課題】 機械的機構のみで作動し、水田の何処にでも設置が可能で、かつ、部品点数が少なく、コンパクトな、水田の水位を一定範囲で調整可能な水位調整装置を提供する。【解決手段】 用水路側に連通する取水口と、水田側に連通する給水口を備えた筐体と、筐体の給水口側の内部に、略鉛直方向に移動可能に設けられたフロートと、給水口の水平部の上端部に設けられた第一の回動軸に取り付けられた弁を備え、弁がフロートの下降に従って前記用水路側に回動することにより、取水口が開放されるように、水位調整装置を構成する。フロートと弁の接続は、フロートの略中央の上方に延在するシャフトの、略上端に取り付けられた保持部材に設けられた第二の回動軸と、弁の取水口側の反対側の面に取り付けられた第三の回動軸に、両端が回動可能に取り付けられた棒状部材によってなされる。【選択図】図1
