Interconnected metering cover plate type valve port

Abstract

The invention relates to an interconnected metering cover plate type valve port. The interconnected metering cover plate type valve port comprises a sensor, a flange, a water inlet, a transformer, a communication interface, an RTU circuit board control chamber, a water outlet, a water level electrode, a cover plate and a photovoltaic power generation plate; the water inlet is arranged at the leftside of a central pipeline of the sensor; the flange is arranged at the left side of the water inlet; the transformer and the communication interface are arranged at the upper end of the sensor; the water outlet is arranged at the right side of the sensor; the opening part of the water outlet is designed upwards; the water level electrode is arranged at the inner side of the opening part of the water outlet; a reversed U-shaped frame is arranged above the water outlet; an electric push rod is installed at the middle of the upper end of the U-shaped frame; the cover plate is arranged at the lower end of the electric push rod; and the lower end face of the cover plate and the opening part of the water outlet are hermetically matched with each other in design. The interconnected metering cover plate type valve port has the advantages that water is horizontally discharged because the opening part of the water outlet is designed upwards so that full-water flowing speed of the central pipeline of the sensor is guaranteed and accurate metering is realized.

Description

technical field [0001] The invention relates to an irrigation control valve for aquatic crops, in particular to a metering cover plate valve port integrated with remote monitoring. 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 modern The actual needs of agricultural intelligent irrigation. Conten...

Problems solved by technology

[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
