Helical labyrinth wide-passage type water filler for filling water into fountain from bottom

Abstract

The invention discloses a helical labyrinth wide-passage type water filler for filling water into a fountain from the bottom, which comprises a hollow round tube with a bottom, wherein a helical labyrinth wide-passage (03) is arranged on the outer wall of the round tube; a water inlet (01) and a ventilating water guiding port (02) are reserved on the upper part of the round tube; a passage inlet filter screen (04) is arranged in the water inlet (01); the water inlet (01) is communicated with the helical labyrinth wide-passage (03) through a passage inlet (06); a water buffering area (07), a water stopping area (08) and a water outlet (09) are reserved at the tail end of the passage (03); the tail end of the passage (03) is communicated with the water buffering area (07) through the passage inlet (06); the water buffering area (07) is communicated with the water stopping area (08); the water stopping area (08) is formed by using the inner cavity of the hollow round tube with the bottom; and meshes are arranged at the bottom of the round tube to form the water outlet (09). The water filler has the advantages of high flow rate and high anti-clogging performance.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a helical tooth labyrinth wide channel type gushing spring root irrigation device, which is used for water-saving irrigation of wide-row economic crops in water-deficient areas. Background technique [0002] The land area of ​​my country's arid, semi-arid and semi-humid drought-prone areas accounts for more than 50% of the total land area of ​​the country, and the cultivated land area accounts for more than 50% of the total cultivated land area of ​​the country. However, agriculture in these areas mainly relies on natural precipitation for supplementary irrigation, and agricultural production levels are greatly affected. limit. Among the water-saving irrigation technologies researched and promoted in my country at present, micro-irrigation has developed rapidly in recent years due to its advantages of water saving, energy saving, high efficiency, and in...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned deficiencies of above-ground and underground drip irrigation projects, some patent applications have proposed a new concept of spring root irrigation, which not only overcomes the shortcomings of above-ground and underground drip irrigation methods, but also increases the capillary service life from 5-8 years to 20 years. Water is directly replenished to the roots of crops, realizing the transformation from irrigated soil to irrigated crops, reducing ground evaporation and clogging of emitters, and improving irrigation water utilization efficiency. However, this technology requires emitters with large flow and high anti-clogging performance. Currently, there is no A true spring root irrigation product
