PROBLEM TO BE SOLVED: To provide a water-sprinkling device intended for solving such problems that a water-sprinkling device sets a watering time of a water spray tube from an electric equipment by a timer, and water spray is controlled by a solenoid valve, so a water-sprinkling device cannot be operated without a power source equipment.SOLUTION: This water-sprinkling device comprises controlling water spray with the water spray tube from the water-sprinkling device through making a control valve operable by buoyancy of a float ball, taking a water level of water in a monitor container in the device, and synchronizing the change of the float ball in the inside of the device with the control valve.COPYRIGHT: (C)2009,JPO&INPIT【課題】 灌水装置は電気設備より散水管の散水時間をタイマーで決めている。散水を制御するにも電磁弁による。電源設備が無ければ灌水装置は動作出来ない。【解決手段】 灌水装置より散水管による散水の制御は、浮玉の浮力によって制御弁が動作可能で、モニター用容器の水の水位を灌水装置に取り入れて、灌水装置内部の浮玉の変化と制御弁が連動していることで解決した。【選択図】図2
