Water circulation irrigation and drainage system for Hetao irrigation area field

Abstract

The invention relates to the technical field of irrigation and drainage systems, and discloses a water circulation irrigation and drainage system for a Hetao irrigation area field. The system comprises a saline-alkali land. A water drainage underground pipe is arranged in the saline-alkali land body. A filtering device is connected to the left end of the water drainage underground pipe. A water storage tank is connected to the left side of the filtering device. A float ball switch is arranged on the left sidewall of the inner cavity of the water storage tank. The top of the water storage tank is at a same level with the top of the saline-alkali land. Two sets of electric water pumps are arranged on the top of the saline-alkali land. The two sets of the electric pumps are respectively positioned on the left and right sides of the top of the water storage tank. Water inlet ports of the electric water pumps are both connected with the inner cavity of the water storage tank through water pipes. Supporting rods are arranged between the water pipes and the inner wall of the water storage tank. A drainage pipe is connected to the left end of the water outlet port of the left electric water pump. With the system, water is recycled, and water usage and distribution are reasonable. An automatic sprinkler irrigation technology is adopted, such that the intelligence degree is high.

Description

Technical field [0001] The invention relates to the technical field of irrigation and drainage systems, in particular to a farmland water conservancy circulating irrigation and drainage system in Hetao irrigation areas. Background technique [0002] The existing automatic irrigation system needs to detect the physiological parameters of plants, soil moisture parameters and many meteorological parameters to calculate and predict the appropriate irrigation time and irrigation volume. It is quite cumbersome, and some detections are difficult for even professionals to grasp, and the structure is complicated. , The equipment is expensive, it is difficult for farmers to accept, and popularization is also very difficult. For example, the Chinese patent application number is 201110056863.7, an automatic irrigation and drainage system for farmland. Irrigation water enters the water level control pool through the water level control valve, and the floating ball drives the water level contro...
