The invention relates to the technical field of paddy field irrigation, and provides a paddy field water gap adjusting system. The system comprises a cross beam, a flashboard, tension springs, a support rod, a limiting body, a buoyancy switch and two stand columns. The stand columns are arranged on two sides of a water gap respectively and are in sealing connection with the two side walls of the water gap respectively. Two ends of the cross beam are connected with the tops of the stand columns respectively. A through hole is formed in the cross beam. The bottom of the flashboard is rotatably connected between the stand columns and is in sealing connection with the bottom of the water gap. One end of each tension spring is connected with the flashboard, the other end of each tension spring is connected with the corresponding stand column or the cross beam, and continuous tensile force is formed between the flashboard and the cross beam or the stand columns. The bottom end of the support rod is hinged to the flashboard, and the top end of the support rod passes through the through hole. The limiting body is movably connected to any axial position of the support rod, and the outer diameter of the limiting body is larger than the diameter of the through hole. The buoyance switch is arranged on a next-level piece of paddy field. When the water level meets a preset requirement, the buoyance switch is turned on to loosen a pulling rope, and accordingly, the flashboard is automatically closed to preset limiting openness.
