Monitoring device for water conservancy micro-infiltration pipe irrigation

Abstract

The present invention discloses a monitoring device for water conservancy micro-infiltration pipe irrigation. The monitoring device for the water conservancy micro-infiltration pipe irrigation comprises a water pump, solenoid valves, a pressure switch and a stabilized power supply, and also a detection circuit, a delay circuit, a control circuit and a prompt circuit; the solenoid valves are three,one ends of the first solenoid valve and the second solenoid valve are respectively connected with a farmland irrigation pipeline and a tap water pipeline, the other end of the first solenoid valve is connected with one end of the third solenoid valve, a water outlet pipe of the water pump, and water inlet ends of micro-infiltration pipes in farmland soil; the pressure switch is arranged on the other end of the first solenoid valve; the stabilized power supply, detection circuit, delay circuit, control circuit and prompt circuit are arranged in a component box and electrically connected withthe water pump, solenoid valves, and pressure switch. When the pipelines are blocked, the water pump outputs pressure clear water into the micro-infiltration pipes to wash the micro-infiltration pipesfor many times, when the micro-infiltration pipes are severely blocked, the monitoring device can prompt management personnel by text messages to achieve purposes of intelligent monitoring and control and also ensures healthy growth of crops.

Description

technical field [0001] The invention relates to the field of micro-seepage pipe monitoring equipment, in particular to a monitoring device for water conservancy micro-seepage pipe irrigation. Background technique [0002] Micro-seepage pipe is a water-saving irrigation facility that has emerged in recent years. It uses rubber as the main raw material, and through polymer foaming technology, countless microscopic small holes are made on the pipe wall, just like the tiny pores on human skin. At the same time, the micro-seepage pipe is buried in the soil below the root of the crop, so that the water and fertilizer nutrients in the micro-seepage pipe slowly and evenly seep out from the capillary pores on the pipe wall, and directly act on the root system of the crop (in practical applications, The farmland irrigation system controls the tap water or the water pumped by the water pump to enter the farmland irrigation pipeline in the required time period, and enters the micro-seep...

Problems solved by technology

[0004] In order to overcome the fact that the existing micro-seepage pipes are buried under the ground, farmland managers cannot immediately find out whether the micro-seepage pipes are blocked, which will affect the production of crops irrigated by the blocked micro-seepage pipes, which will lead to crop yield reduction or even failure. However, the present invention provides real-time monitoring of the pressure in the micro-osmotic tube during application. When the pipeline is blocked in a large area and the pressure becomes high, under the action of related equipment and circuits, it can automatically perform multi- Washing with clean water once with pressure restores the capillary opening of the micro-seepage tube to unblocked, ensuring the healthy production of crops, and when the blockage is serious and the capillary opening of the micro-seepage tube cannot be effectively dredged, the farmland management personnel can be prompted at the first time , replace the micro-seepage pipe after the blockage, or adopt other emergency irrigation methods to irrigate the crops around the blocked micro-seepage pipe, thus achieving the purpose of intelligent monitoring and control, and ensuring the healthy growth of crops.
