Farmland irrigation device
The invention discloses a farmland irrigation device. The farmland irrigation device comprises a support and an observation well; the support is provided with at least one fixed pulley, a pull rope iswound across the fixed pulley, one end of the pull rope is connected with a gate, the other end of the pull rope is connected with a floating body, and a metal block is arranged on the floating body;the gate is installed at a rectangular water outlet of a final-stage channel; the observation well communicates with a farmland, and the water level of the observation well is the same as the water level in the farmland; and at least one magnet is arranged at the bottom of the observation well. The farmland irrigation device is simple in structure, electric power and manpower are not needed, automatic water filling and stopping are realized by combining the effects of magnetic force and buoyancy, the gate is automatically opened or closed according to the water level in the farmland, the operation is very convenient, and manpower cost is saved. The farmland irrigation device can be widely popularized in various functional irrigation channel systems.
本发明公开了一种农田灌溉装置，包括：支架，所述支架上设置有连个至少一个定滑轮，定滑轮上绕设有拉绳，拉绳的一端连接闸门，另一端连接有浮体，浮体上设置有金属块；所述闸门安装在末级渠道矩形放水口处；观测井，所述观测井于农田连通，观测井中的水位于农田中的水位相同；所述观测井的底部设置有至少一个磁铁。该装置结构简单，无需电力、人力，整个装置结构简易，利用磁力和浮力的作用相结合实现自动灌止水，通过农田中的水位高低实现闸门的自动开闭，操作非常方便，节省人力成本。可广泛推广于各种功能灌溉渠道系统中。
