Problems solved by technology

[0003] However, after 2 years of operation of the gravity drip irrigation system of the prior art, the clogging of the emitter generally exceeds 10%, which is much larger than that of the conventional drip irrigation system
The gravity drip irrigation system lacks the most critical anti-clogging proprietary technology, which is the main problem and bottleneck faced by the large-scale application of the gravity drip irrigation system

Embodiment Construction

[0017] A photovoltaic water lifting anti-clogging gravity underground drip irrigation system, as attached figure 1 , 2 , 3, 4, and 5, including four parts: photovoltaic water lifting, water transmission and distribution, intermittent water supply, and pressure-controlled irrigation. The photovoltaic water lifting part consists of a solar cell array 11, a three-phase AC inverter 12 and a three-phase The AC water pump 13 is composed of the output end of the solar battery array 11 connected to the DC input end of the three-phase AC inverter 12 through a cable, and the three-phase AC end output end of the three-phase AC inverter 12 is connected to the three-phase AC water pump 13 through a cable. The input end of the three-phase AC power supply is connected, the water transmission and distribution part is composed of the upper water main pipe, the filter, the lower water main pipe, the branch pipe and the capillary pipe, and the water outlet of the three-phase AC water pump 13 is co...

Abstract

The invention belongs to the technical field of agricultural water-saving irrigation and particularly relates to an anti-blocking gravity-type underground drip irrigation system for photovoltaic water lifting. The anti-blocking gravity-type underground drip irrigation system for the photovoltaic water lifting comprises a photovoltaic water lifting part, a water transporting and distributing part, an interval water supply part and a pressure controlled emitter, wherein the pressure controlled emitter is started to carry out irrigation by an interval water supply device in cycles, mechanical dredging is carried out on the emitter water outlet of the pressure controlled emitter in the irrigation process of every round, and therefore blocking of the emitter water outlet is effectively prevented. The solution that the unstable photovoltaic water lifting is directly used for the irrigation system with the requirements for stable pressure and flows in a low-cost mode is provided. Compared with the solution of stabilizing water supply flows of the water lifting and pressure through storage voltage stabilization of a storage battery, the anti-blocking gravity-type underground drip irrigation system for the photovoltaic lifting water is more economical and effective.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to an anti-clogging gravity underground drip irrigation system for photovoltaic water lifting. Background technique: [0002] Drip irrigation is a kind of local irrigation, which consists of five parts: the first hub, the main pipe, the branch pipe, the capillary pipe, and the sprinkler. ①The head hub is responsible for water intake, pressurization and water treatment, and is composed of water pumps, fertilizer tanks, filters, pressure gauges, flow meters and other components; ②The main pipe plays the role of water delivery; Crop water demand, distribute irrigation water to the irrigation area; ④ Capillary pipes are connected with branch pipes to send water to the roots of crops; ⑤ Irrigators, including: drippers, water outlets, etc., have different types and shapes to Moisten the soil at the root of the crop. Arranging drip irrigation cap...
