Environmentally-friendly high-efficiency water circulation system used for water irrigation

Abstract

The invention discloses an environmentally-friendly high-efficiency water circulation system used for water irrigation. The system comprises a soil layer and a water storing pool, a variable frequencywater pump is installed at the upper end of the soil layer; a water inlet of the variable frequency water pump communicates with the water storing pool through a pipeline; a water outlet of the variable frequency water pump communicates with a water outlet main pipe; the corresponding magnetic poles of a first magnet and a second magnet which are arranged in a damping device are same; according to the principle of repulsion of like poles of magnets, the second magnet slides in a sleeve; an air cushion and a spring are installed; through a plurality of shock-absorbing manners including magnetic shock absorption, air pressure shock absorption and elastic shock absorption, the vibration of the variable frequency water pump during work is reduced, and the service life and working efficiency of the variable frequency water pump are improved; and a stainless steel net plate is arranged in a filter device, and an activated carbon filter net plate is arranged on the right side of the stainless steel net plate, so that the purifying treatment of sewage is greatly improved, and pipeline blocking by impurities in water is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy irrigation, in particular to an environment-friendly and high-efficiency water circulation system for water conservancy irrigation. Background technique [0002] Agriculture is the foundation of national development, and irrigation is an essential step in agricultural production. Among them, irrigation is widely used, without deep leakage and surface loss, and the amount of watering can be adjusted according to the water demand of crops, thereby greatly saving irrigation water. Generally, it can save 30-50% of water, and it can save more than 70% of water on the sandy soil layer with strong water permeability and poor water retention capacity. Increase production. It can control the irrigation in a timely and appropriate amount, so that the moisture in the soil layer can be kept in the suitable range for the normal growth of crops; it will not cause mechanical damage to the soil layer ...

AI Technical Summary

Problems solved by technology

However, the invention patent (201610051202.8) discloses an environmentally friendly and efficient water circulation system for agricultural sprinkler irrigation. Due to defects in this design, the frequency conversion water pump is not equipped with a shock absorber during irrigation, resulting in low irrigation efficiency and high noise. No waterproof and anti-rust treatment is done, which affects the service life of the frequency conversion water pump; and because only activated carbon filter is installed inside the filter device, the purification effect on sewage is poor, resulting in a greatly shortened service time of the filter device and improved filtration efficiency. The device is to install a sewage device, so that the filtered impurities cannot be removed from the pipeline in time, causing pipeline blockage for a long time and affecting irrigation, so the irrigation device needs to be improved
