Intelligent water-saving irrigation system applied to modern agriculture

Abstract

The invention relates to an intelligent water-saving irrigation system applied to modern agriculture. The irrigation system comprises a rainwater collection tank, a fertilizer mixing tank, a water well, a water feeding main pipe, multiple water feeding branch pipes and a controller; a first low-level liquid level sensor is arranged in the rainwater collection tank, and a water outlet is formed inthe side wall of the rainwater collection tank; the fertilizer mixing tank is communicated with the water outlet of the rainwater collection tank through a pipe, a second low-level liquid level sensorand a high-level liquid level sensor are arranged in the fertilizer mixing tank respectively, and a water conveying port is formed in the side wall of the fertilizer mixing tank; a first water pump is arranged in the water well, and the fertilizer mixing tank is communicated with the output end of the first water pump; one end of the water feeding main pipe is communicated with the water conveying port of the fertilizer mixing tank, and the other end of the water feeding main pipe is communicated with the water feeding branch pipes; multiple sprinkler heads are arranged on the water feeding branch pipes; the controller is electrically connected with the first low-level liquid level sensor, the second low-level liquid level sensor, the high-level liquid level sensor and the first water pump respectively. The intelligent water-saving irrigation system has the advantages that the system can automatically supply the water source in the fertilizer mixing tank, it is guaranteed that the whole system can automatically run and irrigate the planting field, and the irrigation system is extremely convenient to use.

Description

technical field [0001] The invention relates to modern agricultural irrigation technology, in particular to an intelligent water-saving irrigation system applied to modern agriculture. Background technique [0002] Fresh water, that is, water with a salt content of less than 0.5g / L, is used in various fields of life. Fresh water reserves account for only 2.53% of the total global water, and 68.7% of them belong to solid glaciers, distributed in difficult-to-use mountains and In the South and North Pole regions, some fresh water is buried deep underground, which is difficult to exploit. As a relatively abundant fresh water resource, the utilization rate of rainwater is not high. [0003] At present, in modern agricultural irrigation, groundwater is mostly used for irrigation, resulting in a large consumption of fresh water resources, and the cost is relatively high. Therefore, it is urgent to improve this irrigation method and strengthen the collection and utilization of rain...

[0002] Fresh water, that is, water with a salt content of less than 0.5g / L, is used in various fields of life. Fresh water reserves account for only 2.53% of the total global water, and 68.7% of them belong to solid glaciers, distributed in difficult-to-use mountains and In the South and North Pole regions, there is still some fresh water buried deep underground, which is difficult to exploit, and rainwater, as a relatively abundant fresh water resource, has a low utilization rate.

[0003] At present, in modern agricultural irrigation, groundwater is mostly used for irrigation, resulting in a large consumption of fresh water resources, and the cost is relatively high. Therefore, it is urgent to improve this irrigation method and strengthen the collection and utilization of rainwater
