Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] The invention relates to a self-circulation greenhouse irrigation system, comprising a rainwater recovery system, a water supply system and a self-circulation irrigation system. The following is a detailed introduction of each system:

[0035] 1. Rainwater recovery system

[0036] Such as figure 1 , 2 As shown, the rainwater recovery system is composed of a rotating flap 12 , a water-guiding partition 13 , a support rod 14 and a water-guiding pipe 15 . The rotating flap 12 is placed on the four walls of the greenhouse, connected to the walls of the greenhouse through a rotating shaft, and can rotate around the rotating shaft, and the bottom of the rotating flap 12 is provided with a support rod 14 for support. When there is no rainfall, the rotating flap 12 is closed upwards, and the greenhouse becomes a closed system; when it is rain...

Abstract

The invention discloses a self-circulating greenhouse irrigation system, comprising a rotary flap arranged on upper edges of four walls of a greenhouse, wherein the rotary flap is connected to the greenhouse walls through a rotating shaft and can rotate around the rotating shaft, and a support bar is arranged between the rotary flap and the walls for supporting; multiple water-guiding partitions are arranged on the rotary flap, the multiple water-guiding partitions guide and collect rainwater on the rotary flap to multiple water-guiding pipes, and each water-guiding pipe is communicated with awater storage tank of a water tower.Through a rainwater recovery system, water flows on the roof of the greenhouse are collected and used during rainfall, which effectively reduces the waste of waterresources and improves comprehensive benefits; in case of no rainfall, the closure of the greenhouse is still kept.

Description

technical field [0001] The invention relates to the field of efficient utilization of agricultural water resources, in particular to a self-circulating greenhouse agricultural irrigation system. Background technique [0002] The water diversion irrigation of agricultural crops is an important guarantee for their high harvest and high yield. The current agricultural irrigation water diversion methods in my country are mostly "extensive" water diversion methods with direct flow pipelines, which are likely to cause waste of water resources and cause certain economic losses. Greenhouse planting technology is used for refined agricultural cultivation. In this field, the conventional pipeline direct current irrigation method is no longer suitable for the development needs of "smart agriculture", so it is particularly important to develop new irrigation methods. Based on the above problems, the present invention proposes a self-circulating greenhouse irrigation system, which adopts...
