Embodiment 1

[0030] Embodiment 1: as Figure 1-3 As shown, the ecological agricultural water-saving irrigation system proposed by the present invention includes a water supply system, a water diversion device, an intermediate water supply unit and a drip irrigation intubation pipe, and the drainage main pipe 27 of the output part of the water supply system is divided into a plurality of drainage branch pipes 29 by the water diversion device. , each drainage branch pipe 29 communicates with the corresponding intermediate water supply unit respectively, and the intermediate water supply unit includes a water tank part and a buffer water bag part, and the two parts are respectively fixed on the corresponding brackets and communicated with each other through the transition pipe 21 as a whole (control water tank The height of the part can change the water inlet speed and water inlet volume of the intermediate water supply unit, and the drip irrigation speed and drip irrigation water volume can b...

Embodiment 2

[0040] Example 2: After the water tank 1 of the intermediate water supply unit in the scheme of Example 1 is filled with water, in order to keep it flowing downward smoothly, the upper end needs to have a vent hole, but the existence of the vent hole leads to the water tank 1 of the intermediate water supply unit The water level may overflow, that is, the continuous water supply of the water supply system will cause a steady stream of water to overflow from the vent hole. In view of this problem, this embodiment improves on the basis of the water tank of Embodiment 1. The top of the water tank 1 is set as a conical top 31, and the inner side is matched with a conical floating body 33 or a floating ball. When the water level rises to a certain height, The conical floating body 33 or the floating ball float upwards to block the air inlet 32 ​​at the upper end. In order to ensure that the conical floating body 33 or the floating ball moves upwards smoothly, a guide rod 35 is fixe...

Embodiment 3

[0041] Example 3: After the water tank 1 of the intermediate water supply unit in the scheme of Example 1 is filled with water, in order to keep it flowing downward smoothly, the upper end needs to have air holes, but the existence of the air holes leads to the water tank 1 of the intermediate water supply unit The water level may overflow. The way to solve this technical problem is different from embodiment 2 in this implementation. In this embodiment, a liquid level sensor needs to be installed in the water tank, and a water inlet solenoid valve is installed on the water inlet or the water inlet pipe of the water tank. And it is controlled by the controller to open and close. When the water level in the water tank is high, it will automatically control the water supply to cut off. In addition to realizing the corresponding functions as in Embodiment 2, this function can also control the water supply volume, aiming at the overall water supply control of some intermediate water...

Abstract

The invention belongs to the technical field of agricultural irrigation, and particularly relates to an ecological agricultural water-saving irrigation system. The ecological agricultural water-saving irrigation system comprises a water supply system, a water distribution device, a middle water supply unit and a drip irrigation insertion pipe, a partition plate is arranged in the water tank, a drainage pipe is connected to the middle of the partition plate, an electromagnetic valve is installed in the middle of the drainage pipe, an irrigation insertion pipe located below the water tank is connected to the bottom of the electromagnetic valve, drainage holes are formed in the outer side of the irrigation insertion pipe, an inner supporting net located on the outer side of the irrigation insertion pipe is installed at the bottom of the water tank, the inner supporting net is sleeved with a filter cotton net, an outer supporting net is arranged on the outer side of the filter cotton net, the outer side of the outer supporting net is wrapped with a protective net, and a water level detector is installed on the inner wall of the water tank. Through the water tank and the irrigation insertion pipe inserted into the ground, the electromagnetic valve can periodically open a channel to immerse water flow into the ground through the irrigation insertion pipe for underground irrigation, evaporation waste of irrigation water on the ground is effectively reduced, and the reasonability and feasibility of the device are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an ecological agricultural water-saving irrigation system. Background technique [0002] Traditional agricultural irrigation mainly refers to the irrigation of agricultural farming areas. Agricultural irrigation methods can generally be divided into traditional ground irrigation, ordinary sprinkler irrigation and micro-irrigation. At present, agricultural irrigation has gradually developed to a unified sprinkler irrigation method. Drip irrigation technology is to slowly drip water to the soil through drip irrigation belts or drip irrigation pipes, and is an irrigation system that directly supplies water, fertilizers or other chemicals to the soil. It does not spray or run water in ditches, it just trickles out slowly and penetrates the soil by gravity and capillary action. Drips of water near the roots of the crops keep the soil in the main root zone of the crop...
