When the water flows into the filter box 411, it passes through the filter screen 422. The filter screen 422 is composed of fine meshes and can effectively intercept impurities, pollutants and other particulate matter in the water. The filtered water becomes cleaner and then flows out through the outlet pipe 412 to prepare for subsequent pressure relief treatment. Through the pressure relief mechanism 2, using the pressure sensor 213 in the discharge part 21, when the pressure sensor 213 detects that the pressure relief mechanism 2 and the hydraulic When the pressure between the power generation modules 1 exceeds a preset threshold, it triggers a corresponding signal, and the pressure sensor 213 sends a signal to the control template, indicating that the current pressure is too high. After receiving the signal, the control template immediately starts the corresponding driving mechanism, and the control template drives the micro motor 215 to start working. The rotation of the micro motor 215 drives the worm 222 to rotate, so the rotation of the worm 222 drives the worm gear 223 to rotate, and the rotation of the worm gear 223 further drives the rotating rod 224 and the adjusting plate 225 to move in the valve body 211.
