Abstract

The invention relates to an automatic control device for canal discharge. The automatic control device is characterized in that a status display is arranged on a box body; an upper-half part of the box body is a semi-closed box body, and a gate at the lower-half part of the box body is embedded into a concave gate sliding chute and a bottom sealing groove; a lifting motor and a descending motor are fixed on a thickening steel plate at the top of the box body; one end of a steel cable is connected with the lifting motor, and bypasses a top plate pulley, a middle steel plate main pulley and a middle steel plate auxiliary pulley; the other end of the steel cable is connected with the descending motor; a gate opening/closing pivot and a gate motion stabilizing pivot are arranged in the middle of the gate and are positioned in a gate sliding stabilizing groove on a back plate of the box body; a controller with signal receiving and transmitting functions and a gate opening height sensor are arranged on the top thickening steel plate; and the controller is arranged on the back plate of the box body and is connected with the status display, the lifting motor and the descending motor. The automatic control device disclosed by the invention has the advantages of timely opening/closing the gate, accurately adjusting the gate height and calculating the canal discharge; and field irrigation can be controlled more accurately, and the utilization efficiency of agricultural water resources is effectively improved.

Description

technical field [0001] The invention belongs to an automatic control instrument, in particular to an automatic control device for realizing the opening and closing time of a channel flow gate. Background technique [0002] my country is a large agricultural country, and irrigated agriculture is very common. Manual gates are used in the traditional channel irrigation process. For areas with developed irrigation canal systems, manual gate operation requires a lot of manpower, and it is difficult to accurately control the channel water level due to the interference of human subjective factors. , gate opening and closing time and flow, resulting in a lot of waste of water resources. In order to improve the utilization efficiency of agricultural water resources, it is necessary to develop an automatic channel flow control device with strong controllability, timing opening and closing of gates, and automatic control of gate height. Contents of the invention [0003] In order t...
