Double pressure stabilizing hydrodynamic variable frequency automatic air adding and water supplying drip irrigation control system

Abstract

The invention relates to a double pressure stabilizing hydrodynamic variable frequency automatic air adding and water supplying drip irrigation control system. The system is characterized in that the system is provided with an automatic pumping, air adding and water supplying device and a plurality of micro-pressure water and fertilizer drip irrigation devices installed in greenhouses; a Venturi oxygen adding device is connected on a water inlet pipe of a high-level water storage pressure stabilizing container in the water supplying device; the water outlet of the water storage pressure stabilizing container is connected to the water inlet of each micro-pressure water and fertilizer drip irrigation device via a water output pipe provided with a hydrodynamic micro-sense feedback device; an automatic water supply control device formed by a water controlling compound series electromagnetic floating water level sensor group, a transfinite water level sensor group and an on demand automatic pumping controller is arranged on the water supplying device and can automatically supply water and protect the pump and pipeline equipment according to the drip irrigation demands of the crops in the greenhouses; each micro-pressure water and fertilizer drip irrigation device comprises a secondary water storage pressure stabilizing tank with a fertilizer liquid barrel; and water outlet pipes of the pressure stabilizing tanks and fertilizer liquid outlet pipes of the fertilizer liquid barrels are connected with a water output pipe on the high-level water storage pressure stabilizing container to form water and fertilizer mixture output pipes leading to water and fertilizer drip irrigation branch pipes in the greenhouses.

Description

technical field [0001] The invention belongs to the technical field of water and fertilizer supply equipment for facility agriculture, and relates to a dual-stable water and fertilizer drip irrigation control system that can automatically and timely supply aerated water to micro-pressure water and fertilizer drip irrigation devices in multiple greenhouses according to the feedback and induction of drip irrigation water dynamic information . Background technique [0002] In recent years, all parts of the country are vigorously promoting facility agriculture, building greenhouses and implementing integrated drip irrigation for energy saving, water saving, and fertilization, but most of them are water supply in the traditional way, and there are no new methods of voltage stabilization, gas addition, and hydraulic frequency conversion. At present, "power frequency conversion equipment" has been used to control water supply in some places with many greenhouses. It is based on wh...

Problems solved by technology

At present, "power frequency conversion equipment" has been used to control water supply in some places with many greenhouses. It is based on whether the entire irrigation area uses water or not, and the shutdown pump has the disadvantages that it cannot meet the drip irrigation water requirements of some greenhouse crops at any time when the water is cut off, and cannot adapt to the requirements of micro-pressure water and fertilizer drip irrigation in greenhouses, especially small and medium-sized greenhouses.
