Field drainage control system

Abstract

The invention provides a field drainage control system, a water tank is arranged beside a field ridge, a water inlet is formed on one side of the water tank which is near to a field, the bottom surface of the water inlet is slightly lower than the field surface, and the top of the water inlet is level with the top of the water tank; a water outlet is formed at the bottom of the water tank, and the water outlet is connected with a drainage pipeline; a buoy is arranged in the water tank; and the buoy is connected with a cover body arranged on the water outlet through a soft rope. The field drainage control system can timely adjust the length of the rope, control the water level in a main tank body and realize the regulation of the water level of the agricultural field according to the different agricultural fields and the different water demands and the drainage requirements of the agricultural fields during the different periods, thereby meeting the requirements of different crops and different development stages of the crops on time and space and realizing the automatic control of field drainage.

Description

technical field [0001] The invention belongs to the technical field of agricultural water and soil engineering, and in particular relates to a field drainage control system. Background technique [0002] European and American countries conduct farmland drainage through underground drainage pipe network systems, and control the opening of drainage gates through computers. In the river network area of ​​our country, farmland drainage outlets are usually temporarily dug according to agricultural needs. The main problems of these field drainage outlets are: first, they are temporarily dug when needed, which is labor-intensive and time-consuming; second, they cannot effectively control the water level of the farmland; The third is that while a large amount of sediment is taken away during drainage, the pollution load of N and P is increased, causing large-scale non-point source pollution. In short, the field ridges and field drainage outlets that are common in farmland at presen...

Problems solved by technology

In the river network area of ​​our country, farmland drainage outlets are usually temporarily dug according to agricultural needs. The main problems of these field drainage outlets are: first, they are temporarily dug when needed, which is labor-intensive and time-consuming; second, they cannot effectively control the water level of the farmland; The third is that while a large amount of sediment is taken away during drainage, the pollution load of N and P is increased, causing a wide range of non-point source pollution.

In short, the field ridges and field drainage outlets that are common in farmland at present cannot effectively control the water level of farmland, and have not played their due role in controlling agricultural non-point source pollution.
