The invention discloses an anti-silt and self-cleaning device for farmland water irrigation. The anti-silt and self-cleaning device comprises a track frame and a main gate, a water tank protruding outwards is fixed to one side of the upstream surface of the main gate in a sealed mode, a water inlet is formed in the lower part of the water tank, a water outlet is formed in the lower part of the water tank or the lower part of the main gate, a conical opening is formed in the position, corresponding to the water outlet, of the inner side of the water tank, the upper side of the conical opening is sleeved with a fusiform opening and closing valve in a matched manner; after the water level in the water tank rises to a certain height, a floating ball floats upwards and opens the fusiform opening and closing valve to quickly discharge water, the water tank floats and moves upwards along with the main gate after water discharging, and in the quick opening process of the main gate, the upstream high-pressure water can quickly enter the downstream position to form shock waves. The impulse type shock waves can be automatically provided, variable-amplitude impact is continuously carried out on the mounting and movement frequency of the channel bottom, and the purpose of automatically cleaning deposited silt at the channel bottom is achieved.
本发明公开了一种农田水利灌溉防淤自清理装置，包括轨道架和主闸门，在主闸门的迎水面一侧密封固定有向外凸出的水箱，水箱的下部设置有进水口，水箱的下部或者主闸门的下部设置有排水口，与排水口对应的水箱内侧设置有锥形口并在其上侧匹配套装有梭形启闭阀，当水箱内水位上升到达一定高度后，浮球上浮且开启梭形启闭阀进行快速排水，水箱排水后随主闸门一起漂浮上移，主闸门迅速开启的过程，上游高压水能快速进入下游形成冲击波。本发明能够自动提供脉冲式冲击波，对渠底安装移动的频率不断进行变幅度冲击，达到自动清理渠底淤积泥沙的目的。
