Problems solved by technology

However, the anti-clogging strategy of the drip irrigation system has not had a significant effect at present. The reason is that there is still a lack of in-depth and systematic understanding of the clogging mechanism of the dripper and the drip irrigation system. Therefore, a large number of drip irrigation simulation tests are necessary for the research of drip irrigation clogging. An easy-to-use and accurate dripper anti-clogging test platform is an important tool for dripper clogging strategy research

Abstract

The invention relates to the technical field of experimental devices, and relates to an intelligent test platform for the anti-clogging performance of a drip irrigation belt. The platform mainly comprises a head water taking system, a pipe network, flow collectors, a lower computer and an upper computer; the outlet end of the head water taking system is connected with a water supply main pipe, andone end of the water supply main pipe is connected with a water supply branch pipe; the pipe network is composed of capillary pipes communicated with the water supply branch pipe through capillary electromagnetic valves; the flow collectors are distributed under the capillary pipes respectively; the lower computer is electrically connected with the flow collectors and the capillary electromagnetic valves; and the upper computer is provided with a database and a control instruction set and communicates with the lower computer. Advantages of traditional measurement are integrated, the upper computer is cooperated with the lower computer to prepare and call the head water taking system, the flow collectors collect data of irrigation flow of the capillary pipes, and the test platform for theanti-clogging performance of a dipper is more intelligent.

Description

technical field [0001] The invention relates to the technical field of experimental devices, in particular to an intelligent testing platform for anti-clogging performance of drip irrigation belts. Background technique [0002] Most of the Yellow River irrigation areas in China are located in arid and semi-arid areas, where water resources are in short supply. Drip irrigation is the irrigation technology with the fastest development speed and the greatest development potential in this area. In areas such as Gansu, Ningxia and Inner Mongolia, the sediment content of the Yellow River water is very high. Even after multi-stage filtration, a large number of particles with a particle size of less than 76 μm still enter the drip irrigation system. The flow channel of the dripper and the cross-section of the water inlet and outlet are narrow and small, and are easily blocked by sediment or organic impurities in the water. Therefore, the problem of dripper clogging is the most impor...
