10. A high-standard farmland water-saving irrigation device and method according to any one of claims 1 to 9, characterized in that: The Method The following steps are involved: S1: When working, the device is moved to a designated position in the farmland, and the two water pipes (4) are respectively drawn out from the two storage vertical cylinders (10), and then one end of the two water pipes (4) is respectively placed on the two arc-shaped lower bottom blocks (12), and then the two driving screws (13) are rotated to make the two arc-shaped upper pressing blocks (11) descend to clamp and fix the two water pipes (4) respectively; S2: Then the first motor (20) drives the rotating disk (17) to rotate via the rotating rod (19), and the two rotating disks (17) are meshed and connected with each other through the two gears (18), so that the two rotating disks (17) rotate in opposite directions, and the two rotating disks (17) drive the two water pipes (4) to rotate until the multiple nozzles (9) are all located above the crops in the farmland, and then the water pump (16) is started to work, and the water in the water storage tank (2) is introduced into the water pipe (4) through the water diversion hose (15), and then sprayed onto the crops through the multiple nozzles (9), and at the same time, the device is moved forward at a uniform speed through the walking wheel (28), thereby completing the irrigation work; S3: When the height of the two water pipes (4) needs to be adjusted according to the height of the crops, firstly, the second motor (25) drives the bidirectional screw (24) to rotate, so that the two sliders (26) move closer to or farther away from each other, and the height of the two water pipes (4) can be raised or lowered by cooperating with the two transfer rods (27) until they are moved to a height position suitable for the crops, thereby greatly improving the practicality of the device; S4: When the device is not in use, firstly, the two driving screws (13) are rotated in the opposite direction to move the two arc-shaped upper pressing blocks (11) upward, and then the two water pipes (4) are removed from the two arc-shaped lower bottom blocks (12) respectively, and are inserted into the two storage vertical cylinders (10) respectively for storage, thereby greatly reducing the space occupied by the water pipes (4) and preventing the water pipes (4) from being damaged by external collisions; S5: During operation, the remaining amount of water in the water storage tank (2) can be observed in real time through the transparent observation window (31) and the scale (32), so that water can be added in a timely manner through the water filling port (30); S6: When water is added to the water storage tank (2) through the water inlet (30), the filter cotton pad (33) is used to filter small particles of impurities in the water to prevent them from being accumulated in the nozzle (9) for a long time and causing blockage, which affects the normal use of the device. The filter cotton pad (33) is supported by the metal screen (35) to prevent the filter cotton pad (33) from being deformed and damaged due to the impact of water and gravity, which affects the normal filtering work. When the filter cotton pad (33) needs to be replaced or cleaned, the replacement plate (34) is pulled to extract the metal screen (35) together with the filter cotton pad (33) from the water storage tank (2), and the filter cotton pad (33) can be cleaned or replaced.
