5. The water conservancy irrigation device with environmental protection function according to claim 4, characterized in that: A branch three-way valve (23) is fixedly provided in the middle of the opposite face of a pair of fixed side plates (22). The top end of the high pressure drain pipe (19) is connected to the water inlet end of the main control three-way valve (26). A pair of telescopic pipes (27) are provided at the drain end of the main control three-way valve (26). The outer end of each telescopic pipe (27) is connected to the water inlet end of the branch three-way valve (23) on the corresponding side. Each of the branch three-way valves (23) has a pair of atomizing branch pipes (24) at its drain end. The outer end of each atomizing branch pipe (24) passes through the fixed side plate (22) on the corresponding side and is connected to the atomizing nozzle (25).

6. The irrigation method of the environmentally friendly irrigation device according to claim 5, characterized in that, Includes the following steps: Step 1: Start the servo motor (37). The motor shaft of the servo motor (37) drives the small diameter sprocket to rotate synchronously. The small diameter sprocket drives a pair of linkage sprockets, linkage shaft (41), and rocker arm connecting rod (42) to rotate synchronously through the first chain belt (38). The other linkage sprocket drives the large diameter sprocket, fixed shaft (31), and collar to rotate synchronously through the second chain belt (39). Step 2: When the rocker arm connecting rod (42) rotates, the rocker arm pin (43) and the elliptical ring (47) form a limiting action, driving the elliptical ring (47), L-shaped slide plate (46), and elliptical slider (45) to slide back and forth along the elliptical sliding hole. The L-shaped slide plate (46) simultaneously drives the hollow rod (2), fixed horizontal plate (21), and a pair of fixed side plates (22) to slide up and down along the sleeve (16). Step 3: When the collar rotates, it drives the limiting rod (33), the limiting slide plate (34), and the limiting pin (32) to rotate synchronously. A pair of limiting pins (32) and the limiting slide groove alternately form a limiting effect, driving the limiting slide plate (34) to slide alternately along the limiting notch, driving the limiting cylinder (35), the limiting retaining ring (36), the hollow rod (2), the fixed horizontal plate (21), and a pair of fixed side plates (22) to reciprocate. Step 4: Start the water pump (11). Under the action of the water pump (11), the irrigation water enters the bottom tank (1) through the inlet pipe and outlet pipe. After being filtered by a pair of filter plates (12) and activated carbon filler (13), the irrigation water flows into the middle of the bottom tank (1). Step 5: Start the high-pressure pump (17). Under the action of the high-pressure pump (17), the irrigation water flows through the high-pressure pumping pipe (18), the high-pressure drain pipe (19), the main control three-way valve (26), the telescopic pipe (27), the branch three-way valve (23), and the atomizing branch pipe (24) into the atomizing nozzle (25) and performs atomized irrigation through the atomizing nozzle (25).
