Abstract

The invention discloses a grid plate type water metering and control device applicable to field irrigation. The device is characterized by comprising a water passing box (3), a water inlet gate (4), a water-permeable grid plate (8), an electromagnetic lock (5), a controller (6) and a linear displacement sensor (7). The water passing box (3) is installed in a ditch slope (1), the water inlet gate (4) is installed on the water inlet side, the water-permeable grid plate (8) is installed on the water outlet side, the linear displacement sensor (7) is installed on the top of the water outlet side of the water passing box (3), the controller (6) is fixed to the top of the water passing box (3) and is connected with the linear displacement sensor (7) and the electromagnetic lock (5), and the controller (6) receives the signals of the linear displacement sensor (7), and can also control the electromagnetic lock (5) to be opened and closed. The grid plate type water metering and control device applicable to field irrigation has the advantages of being simple in structure, accurate in metering, wide in measuring range, capable of achieving remote automatic control easily and the like, and is particularly applicable to accurate metering of and control over the water consumption of field irrigation.

Description

technical field

[0001] The invention relates to a grid-type water metering and control device suitable for field irrigation, which belongs to the technical field of farmland water conservancy. Background technique

[0002] Water resources are a major issue that people are increasingly concerned about. my country's agricultural water consumption accounts for nearly 70% of the country's total water consumption, of which 90% is consumed in farmland irrigation. Irrigated agriculture plays an irreplaceable role in supporting food production. However, with the rapid development of my country's social economy, the problems existing in irrigation in irrigation areas are becoming more and more prominent, such as the aging of irrigation area projects leading to the failure of water transmission and distribution functions, the lack of water resources in northern my country but the serious phenomenon of wasting water, water use efficiency and Productivity is lower and so on. At present,...
