用于受控浇水的独立机械装置
Stand-alone mechanical device for controlled watering
US-7921865-B2提供一种纯机械的自动浇水装置，用于植物灌溉。
专利摘要
本发明涉及一种纯机械的独立式可控喷洒浇水装置，其中土壤模拟构件具有与下方可倾斜杯相关联的吸收体，有助于确定两次浇水之间的间隔。平衡臂承载吸收体和环形磁铁，通过压缩弹簧安装和平衡，有助于确定阀门的开启和关闭时间。阀门包括一个液压继电器，其喷嘴响应于磁场的位移触发阀门的开启或关闭。一个不透水套筒包围芯体和喷嘴。一个滑动罩允许调节决定浇水持续时间的参数之一。一个恒温元件具有可调节位置，防止在阳光下浇水。该装置可旋转地安装在枢轴上，枢轴包括套筒的底座和尾翼。
Original abstractThe invention concerns an exclusively mechanical stand-alone device for controlled watering by sprinkling, wherein a soil simulating member, having an absorbent body associated with a reclinable cup arranged beneath, contributes to determination of the interval between two watering operations. A balance arm, bearing the absorbent body and an annular magnet, is mounted and balanced by a compressed spring, contributing to the determination of the opening and closing times of a valve. The valve includes a hydraulic relay with a nozzle triggering its opening or closure, in response to the displacement of the magnet field. An impermeable sleeve encloses the core and the nozzle. A sliding canopy enables one of the parameters determining the duration of the watering operation to be adjusted. A thermostatic element has an adjustable position preventing watering in sunshine. The device is mounted rotating on a pivot including the base of the sleeve and a tail unit.
