Interconnected metering water-saving valve port

Abstract

The invention relates to an interconnected metering water-saving valve port. The interconnected metering water-saving valve port comprises a sensor, a flange, a water inlet, a converter, a communication interface, an RTU circuit board control chamber, a water outlet, pipeline built-in water level measurement and control electrodes, a cover plate and a photovoltaic power generation panel. The interconnected metering water-saving valve port has the advantages that since a port of the water outlet is designed to face upwards and feeds water horizontally, the full water flow velocity of a center pipeline of the sensor is ensured, and metering is accurate; since the water outlet is provided with the pipeline built-in water level measurement and control electrodes, the water level can be measured and controlled, the valve port is opened when water flows in the pipeline and is closed when no water flows in the pipeline, and water in a rice field is prevented from flowing back; a field water level measurement and control electrode is arranged and can automatically control the water level of the rice field; and a corrugated waterproof expansion sleeve arranged on the outer side of an electric push rod has the effective waterproof effect while ensuring the effective telescopic performance of the push rod, and the service life of the push rod is guaranteed.

Description

technical field [0001] The invention relates to an irrigation control valve for aquatic crops, in particular to an interconnected metering water-saving valve port for monitoring and metering water supply and closing water through a wireless network. Background technique [0002] At present, there are mainly two kinds of automatic valve ports for water supply and shutdown control in rice fields. One is the floating cover plate port. In order to save water resources, shallow irrigation is generally used for rice growth. In shallow water areas, it is difficult to exert buoyancy, and it is impossible to accurately control the water level in the field. The second is the automatic valve port. Although it meets the requirements of automatic water supply and shut-off, there are no sensors and wireless communication ports on the valve body, which cannot meet the actual needs of intelligent metering irrigation. Therefore, it is necessary to improve the existing technology to meet mode...

[0002] At present, there are mainly two kinds of automatic valve ports for water supply and shutdown control in rice fields. One is the floating cover plate port. In order to save water resources, shallow irrigation is generally used for rice growth. In shallow water area, it is difficult to exert the buoyancy effect, and it is impossible to accurately control the water level in the field

The second is the automatic valve port. Although it meets the requirements of automatic water supply and shut-off, there are no sensors and wireless communication ports on the valve body, which cannot meet the actual needs of intelligent metering irrigation. Therefore, it is necessary to improve the existing technology to meet modern The actual needs of agricultural intelligent irrigation
