Rainwater collecting and utilizing system for energy-saving greenhouse

Abstract

The invention relates to the technical field of greenhouse rainwater collection, and particularly relates to a rainwater collecting and utilizing system for an energy-saving greenhouse. The rainwater collecting and utilizing system comprises a box body, wherein a groove is formed in the top surface of the box body in the length direction; rotatable collecting grooves are formed in the groove; the collecting grooves are used for collecting rainwater; the end surfaces of one sides of the adjacent collecting grooves are connected through connecting plates; a movable plate is rotationally mounted on one side, facing the inner wall of the box body, of one connecting plate through a bearing part; a driving shaft is led out of the movable plate; and the end part of the driving shaft penetrates through the box body and extends to the outside of the box body. The rainwater collecting and utilizing system solves the problems that rainwater collected by utilizing greenhouse rainwater collecting equipment is contaminated by impurities in the long-term external arrangement process and the rainwater receiving rate is not high. The rainwater collecting and utilizing system can ensure that rainwater after standing is quickly transferred out and is convenient to utilize, and can further enlarge the area of a rainwater receiving notch and improve the rainwater receiving rate.

Description

technical field [0001] The invention relates to the technical field of rainwater collection in greenhouses, in particular to an energy-saving rainwater collection and utilization system for greenhouses. Background technique [0002] Greenhouse buildings promote the recycling of rainwater, so as to maximize the comprehensive utilization rate of the water environment system and reduce energy consumption. The collection of roof rainwater is an important way to make good use of water resources. The existing rainwater collection in greenhouses has the following problems in practical application: rainwater collection requires the installation of water receiving tanks in the open air. Although the existing water receiving tanks can filter rainwater, the standing rainwater is exposed to the air for a long time, and there is still contamination. The possibility of fine impurities and particles will affect the subsequent use; at the same time, the water receiving efficiency of the si...
