Quantitative and constant-temperature irrigation device for flow-storage separation

Abstract

The invention provides a quantitative and constant-temperature irrigation device for flow-storage separation. The quantitative and constant-temperature irrigation device comprises a solar water heater, a treatment water tank, a water storage tank, a main electric valve and an auxiliary electric valve. The interior of the treatment water tank is provided with a solar coil pipe. The treatment water tank is connected with the water storage tank through a hot water conveying pipeline. The water storage tank is connected with the water storage tank through a cold water conveying pipeline. The right side of the water storage tank is connected with a water outlet pipeline, on which the main electric valve is arranged. The right side of the water storage tank is connected with a drainage soft pipe, on which the auxiliary electric valve is arranged. Compared with the prior art, the quantitative and constant-temperature irrigation device for flow-storage separation has following beneficial effects: automatic control over fixed quantity and water consumption crop irrigation are achieved; and water waste during management caused by improper management in water-saving irrigation projects such as sprinkling irrigation and micro-irrigation is avoided.

Description

technical field [0001] The invention relates to a flow storage separation quantitative constant temperature irrigation device, which relates to the flow storage separation irrigation technology. Background technique [0002] Among the known technologies, domestic and foreign research and application irrigation techniques and methods in the field of agricultural high-efficiency water-saving irrigation technology mainly include: sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, drip irrigation under mulch, underground seepage irrigation, etc. The key technology of irrigation water outflow in these water-saving irrigation systems is-irrigator, such as sprinkler nozzle; [0003] Sprinkler irrigation and micro-spray irrigation sprinklers are spraying water appliances. According to the nozzle structure, they can be divided into three types: rotary nozzle, fixed nozzle and spray hole tube. Among them, the rotary nozzle (jet nozzle) is the most widely used in my cou...

AI Technical Summary

Problems solved by technology

[0008] There are obvious problems in the technology of underground seepage irrigation emitters: seepage irrigation is continuous energy consumption from beginning to end, spring irrigation affects the normal growth of crops due to the low water temperature of the seepage irrigation system, seepage irrigation itself does not have the ability of irrigation quota self-control, underground water delivery seepage irrigation pipes The phenomenon of solid particles and biological clogging of irrigation water due to the relationship with the soil environment, large investment in management, high operation and maintenance costs, etc.
