Floating irrigation device

Abstract

The invention provides a floating irrigation device. The device comprises a hollow assembly and a floating assembly housed in the hollow assembly, a water inlet is formed in one end of the hollow assembly, a drain port is formed in the other end of the water inlet, a hollow chamber is formed between the water inlet and the drain port, the hollow chamber accommodates the floating assembly, the floating assembly can be displaced upward and downward in the hollow chamber, a drain small port is formed between the drain port and the floating assembly, when liquid flows downward, the floating assembly flows down, blocks the drain port, and prevents a large amount of liquid from flowing out, and only a small amount of the liquid flows out from the drain small port; when the liquid stops flowing,the floating assembly floats upward, and a residue flows to the drain port to prevent blocking.

Description

technical field [0001] The invention relates to a floating irrigation device utilizing low pressure or gravity irrigation and having the functions of reducing flow, watering and exhausting. Background technique [0002] At present, the drip irrigation technology developed in Israel is relatively water-saving, but it also has high requirements for water quality. As long as there is no regular flushing of the filter device, it is easy to cause pipeline blockage and affect the irrigation system. In addition, due to the high investment cost and the need for training in equipment maintenance, it is only suitable for planting high-value crops at present, and it is difficult to promote it on a large scale. Although many parties are working on the design of the dropper to reduce clogging, it still cannot prevent clogging from happening. [0003] refer to Figure 5 As shown, it is the trace irrigation technology published in China. The core of this technology is the water-saving com...

AI Technical Summary

Problems solved by technology

[0004] Disadvantage 1: The turbulence caused by this method can remove the light slag with a specific gravity smaller than the liquid, but the heavy slag with a larger specific gravity than the liquid is still not easy to remove, and it is easy to settle in the trace filling film, which will still cause blockage in the long run

[0005] Disadvantage 2: The discharged light slag still flows in the pipe and is not discharged out of the pipe. After long-term accumulation, the light slag in the pipe gradually increases, which will still cause blockage

[0006] It can be seen that the above-mentioned existing trace irrigation technology still has many defects, is not a good design, and urgently needs to be improved.
