All data is transmitted to a microcontroller for comprehensive analysis, which automatically adjusts the opening of the regulating valve in the flange pipe, dynamically changing the influent volume to match the real-time water requirements of the plants. This system eliminates the need for manual pre-setting of irrigation volume, overcoming the limitations of traditional manual operation.

This promotes the transformation of landscaping irrigation towards intelligence and precision, fundamentally different from existing irrigation devices that rely on manual intervention.

[0016] 3. This invention achieves multi-level and efficient utilization of water kinetic energy, eliminating the need for additional drive devices such as motors and air pumps, significantly reducing equipment energy consumption and operating costs. After the water flows into the power cylinder, it drives the first water-driven blade to rotate the shaft, providing power for the sliding of the slide table and the swing of the sleeve. On the other hand, after the water flows into the water-driven housing, it impacts the second water-driven blade. Through the intermittent transmission of some gears and linkage gears, it realizes the automatic switching of six different spraying modes of the nozzles, adapting to the water requirements of different plants. At the same time, the rotational power of the first water-driven shaft also drives the reciprocating drum mechanism through the sector gear, providing stable air pressure for the pneumatic push rod, realizing the reciprocating extension and retraction of the liquid guide tube. This multi-energy power coordination mode fully converts the water kinetic energy into mechanical motion and air pressure energy, forming a closed-loop power cycle. Compared with traditional irrigation devices that require multiple power sources, the structure is simpler and the energy consumption is lower. Attached Figure Description
