Irrigation terminal device with water measuring function

Abstract

The invention relates to an irrigation terminal device with a water measuring function. The device consists of a three-phase asynchronous brake motor, a speed reducer, a rotary shifting rod, an open-position detection switch, a clamp, a close-position detection switch, multiple valve bodies, a support, a valve switch, water pipes, a circuit, a local processing device, a solar power generation plate, a master control cabinet and a terminal controller, wherein the speed reducer and the rotary shifting rod are mounted on the three-phase asynchronous brake motor, the clamp is connected with the support, the close-position detection switch is mounted on the corresponding valve body, and the three-phase asynchronous brake motor, the speed reducer, the rotary shifting rod, the open-position detection switch and the close-position detection switch are mounted on the support. The irrigation terminal device is characterized in that the valve bodies are connected by the water pipes, and the circuit is connected with the three-phase asynchronous brake motor, the open-position detection switch, the close-position detection switch, the local processing device and the solar power generation plate. The irrigation terminal device has the advantages of being flexible, convenient, easy to operate, capable of reducing labor consumption and low in cost.

Description

technical field [0001] The invention relates to a remote-controlled automatic irrigation terminal device, which is especially suitable for irrigation in farms, large-scale gardens, large-scale flower gardens, etc. that have certain requirements for remote control and automation. Background technique [0002] In the farmland irrigation of the Yellow River floodplain, there are often a large number of small-area irrigation areas. For such small-area irrigation areas, it is suitable to use the irrigation pipe as the irrigation terminal, and directly divert water from the channel for irrigation. For irrigation to the pipe, there is still no ideal means of measuring water at present. Some irrigation districts use water meters, but water meters are expensive and inconvenient to maintain; another alternative is to measure water in the channel behind the pipe, but the water loss between the pipe and the water point of the channel cannot be measured. Large-scale channels or irrigati...

Some irrigation areas use water meters, but the water meters are expensive and inconvenient to maintain; another alternative method is to measure water in the channel behind the pipe, but the water loss between the pipe and the water point of the channel cannot be measured

Large-scale channels or irrigation areas can use the supporting hydraulic structures on the irrigation canal system, such as gates, culverts, aqueducts, inverted siphons, etc., to measure water, but for irrigation pipes with much smaller dimensions and water delivery, the current water-measuring structures objects, the cost is relatively high, and the structural form is not applicable
