Water self-supplying agricultural greenhouse system

Abstract

The invention belongs to the technical field of agricultural greenhouses, and specifically discloses a water self-supplying agricultural greenhouse system. The system includes an optical system disposed in the greenhouse, a water generating system disposed on one side of the optical system and a blower connected with the water generating system, wherein the optical system includes a Fresnel lens,a first concave lens disposed at the condensing point of the Fresnel lens and solar limited-frequency reflecting glass disposed under the first concave lens, and the water generating system comprisesan insulating layer, a selective absorbing coating and a moisture adsorbing layer; the moisture adsorbing layer includes a adsorbent material layer and a metal thermally conductive rod, and the insulating layer is transmissive to infrared light reflected by the solar limited-frequency reflecting glass. Through the system, gradient utilization of sunlight is realized, cleanness and environmental protection can be achieved, consumption of non-renewable energy is reduced, and meanwhile the water self-supplying function of the greenhouse can be achieved; in a water-deficient area, not only agricultural water can be provided, but also supplementing of domestic water can be achieved, so that the problem of water shortage is alleviated.

Description

technical field [0001] The invention belongs to the technical field of greenhouse water supply, and more specifically relates to an agricultural greenhouse self-supply water system. Background technique [0002] With the continuous progress of the society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization, and the new type of facility agriculture is sought after by people in the industry. The so-called agricultural equipment is actually greenhouse facilities, which are not limited by time and space, and can carry out agricultural production in special environments such as plateaus, deep mountains, and deserts. China is a large agricultural country, and farmers account for more than half of the total population. The space for agricultural innovation and application is infinite. The agricultural equipment industry has moved from behind the scenes to the front of the stage. Throughout the domestic greenhouse ind...

Problems solved by technology

[0005] Chinese patent CN107996209 A provides an intelligent environment-friendly planting greenhouse, which is used for planting plants, including a ceiling, side walls, sensors, controllers and operation terminals. The ceiling includes a rainwater collection tank connected to a water storage tank , a flexible thin-film solar module is arranged under the rainwater collection tank, the sensor includes a plurality of sensors, the sensors detect the humidity, light, and temperature in the greenhouse, and the controller obtains test data from a plurality of sensors, and controls the operation according to the test data The terminal solves the problem that the current intelligent environmental protection planting greenhouses are not highly intelligent

This scheme makes full use of natural precipitation resources to improve the production efficiency of greenhouses, but it is not suitable for water-scarce areas such as western my country
