Automatic control drainage device for farmland
The invention discloses a farmland automatic control drainage device which comprises a three-way pipe, the three-way pipe is composed of a first pipe body and a second pipe body, a water inlet part of the first pipe body is rotationally connected with a flashboard, a balancing weight is arranged in the second pipe body, the balancing weight is connected with a rope, one end of the rope extends out of the second pipe body to be fixedly connected with the flashboard, and the other end of the rope extends out of the second pipe body to be fixedly connected with the flashboard. The flashboard is under the action of water pressure, the water pressure on the bottom of the flashboard is gradually increased along with the increase of the water depth of the farmland, and the water pressure on the top of the flashboard is relatively small, so that the flashboard is rotated under the action of the water pressure to open the water inlet part, and the flashboard is driven by the rope to lift the balancing weight to discharge the farmland water. The rope is pulled to enable the balancing weight to rise, at the moment, the farmland accumulated water enters the first pipe body and is automatically discharged into the field canal through the first pipe body, automatic drainage operation of the farmland accumulated water is achieved, and the device is of a mechanical structure, does not contain electric elements, control elements and the like and is suitable for being used in large-area farmland.
本发明公开了一种农田自动控制排水装置，包括三通管，所述三通管由第一管体和第二管体组成，所述第一管体的进水部转动连接有闸板，所述第二管体内设置有配重块，所述配重块上连接有绳索，且绳索一端伸出第二管体与闸板固定连接，所述闸板用于农田水深时因压差旋转并通过绳索带动配重块升高以将农田水排出，本发明的闸板受水压力作用，随着农田水深的加大，闸板底部受水压力逐渐变大，闸板顶部受水压力相对较小，因此，闸板受水压力作用旋转打开进水部，从而拉动绳索，使得配重块上升，此时，农田积水进入第一管体，通过第一管体自动排入农渠，实现农田积水的自动排放作业，本装置采用机械结构，不含电力、控制等元件，适合在大面积的农田使用。
