Constant-negative-pressure irrigation system applied to agricultural irrigation

Abstract

The invention discloses a constant-negative-pressure irrigation system applied to agricultural irrigation. The constant-negative-pressure irrigation system structurally comprises a guide rail, a floating ball, a supporting rod, a sealing plate, a water inlet pipe, a first switch valve, a water storage barrel, an auxiliary water inlet pipe, a fault alarm device, a crop soil layer, a multi-cavity ceramic water seepage pipe, an irrigation water pipe and a second switch valve, wherein the vertical guide rail is arranged on the inner wall of the water storage barrel, the sealing plate is arranged on the guide rail and is in sliding connection with the guide rail, the sealing plate is perpendicular to the guide rail, and the floating ball is vertically connected to the bottom of the sealing plate; the top of the sealing plate is in contact with a water outlet of the water inlet pipe, and a water inlet of the water inlet pipe is communicated with a water inlet of the auxiliary water inlet pipe; the auxiliary water inlet pipe is provided with the first switch valve, and a water outlet of the auxiliary water inlet pipe is communicated with the highest position of the irrigation water pipe.According to the constant-negative-pressure irrigation system applied to agricultural irrigation, the fault alarm device in the system can sound an alarm in time when equipment breaks down, workers can conveniently handle faults in time, water shortage of crops is prevented, the loss is reduced, and risks are reduced.

Description

technical field [0001] The invention relates to a constant negative pressure irrigation system applied to agricultural irrigation and belongs to the field of constant negative pressure irrigation systems for agricultural irrigation. Background technique [0002] Ultra-water-saving negative pressure differential irrigation is a new type of irrigation method that fully utilizes natural forces (capillary phenomenon, gravity, siphon) and uses special porous ceramic seepage pipes to construct ultra-water-saving and energy-saving irrigation methods. The water supply head is "negative" during irrigation, that is, the elevation of the irrigation water source is lower than the elevation of the porous ceramic seepage pipe (irrigator), and the entire irrigation process does not require external water lifting and pressurizing equipment. [0003] Existing negative pressure irrigation cannot detect equipment failures in time, and crops are prone to water shortage, resulting in losses and ...
