Method and apparatus for automatically adjusting electric gate vale

Abstract

The invention relates to a method and an apparatus for automatically adjusting an electric gate valve, belonging to the technical field of water measurement and measurement and control of a gate valve in the water conservancy industry. According to a technical scheme, the apparatus comprises a gate valve controller (1), a communication interface (2) and a frequency converter (3), wherein the gate valve controller is respectively connected with the communication interface and the frequency converter; and the apparatus also comprises a gate position sensor (5), a water level sensor (6) and a power supply (7) which are respectively connected with the gate valve controller (1); the number of the water level sensor is at least one; the frequency converter is respectively connected with the power supply and a gate valve deceleration motor (8); and the gate valve deceleration motor is connected with a gate valve opening and closing machine (9). The method and the apparatus for automatically adjusting the electric gate valve have the beneficial effects that by adjusting the speed of the gate valve, gate valve water measurement and monitoring parameters are used for setting a value according to the requirement so as to realize the variable-frequency PI adjustment of the gate: high-speed running, low-speed approaching, tail-end crawling and precise flow, and the flow of the gate valve is automatically and precisely adjusted.

Description

technical field [0001] The invention relates to a method and a device for automatically adjusting the flow of an electric gate, belonging to the technical field of gate water measurement and measurement and control in the water conservancy industry. Background technique [0002] At present, in the water conservancy industry, electric gates are the most commonly used water volume control and adjustment equipment. When the existing electric gates are modified for water measurement, due to the high operating speed of the gates, only water volume measurement can be realized, but automatic and accurate flow cannot be realized. Adjustment, can not be automatically adjusted with the flow or water level of the relevant channels, can not realize the automatic adjustment of the gate flow according to the demand, can not realize the adjustment and control of the fixed time, constant flow, and fixed water volume, and can not accurately adjust the flow of agricultural irrigation channels ...
