Constant-humidity agricultural water supply system based on energy conversion

Abstract

The invention relates to a constant-humidity agricultural water supply system based on energy conversion. The system comprises an infiltration collection port, a first infiltration pipeline, a first relay cavity, a plurality of second infiltration pipelines, a plurality of second relay cavities, a plurality of third infiltration pipelines, a plurality of third relay cavities and a plurality of permeable membranes; the infiltration collection port is connected with the first relay cavities through the first infiltration pipeline; the first relay cavity is connected with the second relay cavitythrough the second infiltration pipelines; the second relay cavities are connected with the third relay cavities through the third infiltration pipelines; the third relay cavities are provided with water seepage ports; the permeable membranes are respectively arranged at the joint of the first relay cavity and the second infiltration pipelines, the joint of the second relay cavities and the secondinfiltration pipelines and the water seepage ports of the third relay cavities; the first relay cavity, the second relay cavities and the third relay cavities are each provided with a concave groove,and the concave grooves are formed in the connecting position of the first relay cavity and the second infiltration pipelines, the connecting position of the second relay cavities and the second infiltration pipelines and the periphery of a water seepage opening of the third relay cavities respectively.

Description

technical field [0001] The invention relates to the fields of energy conversion and water supply, in particular to an energy conversion-based constant humidity agricultural water supply system. Background technique [0002] With the advocacy of conservation-oriented thinking, the awareness of agricultural water-saving irrigation has become more and more accepted and valued by the majority of farmers. Therefore, in farmland irrigation projects, the thin dew irrigation for rice and other crops involves water saving issues. The so-called thin dew irrigation refers to thin water, shallow irrigation, and often exposed fields. As a result, water-saving irrigation valves that look like fire hydrants are quietly seen in the fields, and water-saving or waterproofing of fields can be realized by means of such water-saving valves. However, in the prior art, water saving is often limited to water saving during irrigation, that is, water saving is only considered from how to control the...

Problems solved by technology

[0004] In view of the existing technology, water saving is often limited to water saving during irrigation, that is, water saving is only considered from how to control the amount of water required for irrigation, and water saving is not considered from the aspect of how to improve the efficiency of irrigation. Instead, it leads to the waste of water resources. The present invention provides a constant humidity agricultural water supply system based on energy conversion
