when the water stored in the water storage cavity 33 reaches a set amount, the second piston 56 moves downwards to abut against the third piston rod 67 and push the third piston rod 67 to move downwards, the third piston rod 67 drives the third piston 64, the fixing plate 68 and the limiting rod 69 to move downwards, negative pressure generated by downward movement of the third piston 64 is conveyed into the auxiliary piston cavity 82 through the air pipe 62, so that the fourth piston 83, the rotary disc 74 and the second gear 75 move leftwards, the second gear 75 is separated from contact with the rack 40, the second gear 75 is meshed with the fourth gear 79, the limiting rod 69 is separated from contact with the limiting hole 70, under the action of water pressure in the water storage cavity 33, the watertight box door 71 rotates leftwards and is opened, so that sewage in the water storage cavity 33 is conveyed into the impeller cavity 48 through the input pipe 31 and drives the impeller 47 to rotate, the impeller 47 drives the auxiliary generator shaft 49 to rotate, so that the auxiliary generator 23 generates electricity, and because the water flow rate flowing into the impeller cavity 48 through the input pipe 31 after the water storage cavity 33 stores water can enable the impeller 47 to, therefore, the efficiency of converting water flowing energy into electric energy can be improved, then sewage flows into the sewer 16, wave energy formed by the sewage in the sewer 16 is up and down moved by the buoyancy plate 19 and the lifting rack 20, the lifting rack 20 drives the first gear 43 to rotate through meshing connection when moving, and when the lifting rack 20 moves up, the first gear 43 rotates and can drive the one-way clutch 42 and the first rotating shaft 41 to rotate, so that the air pump 21 generates air flow, the air flow is conveyed into the air storage box 22 through the waste material box 54 to be stored, and when the lifting rack 20 moves down, the first gear 43 cannot drive the first rotating shaft 41 to rotate through the one-way clutch 42; after the water in the water storage cavity 33 is discharged, the second piston 56 moves upwards to reset under the action of the second compression spring 60, the watertight box door 71 rotates rightwards to reset under the action of the auxiliary torsion spring 72, the third piston 64 moves upwards to reset under the action of the third compression spring 66, and the damping force between the third piston 64 and the inner wall of the piston cavity 65 is larger, so that the upward moving speed of the limit rod 69 is smaller than the rightward rotating resetting speed of the watertight box door 71, after the watertight box door 71 resets, the limit rod 69 moves upwards to extend into the limit hole 70, meanwhile, the upward moving speed of the limit rod 69 is far smaller than the upward moving resetting speed of the second piston 56, after the second piston 56 moves upwards to reset, the fourth piston 83 can drive the second gear 75 to move rightwards to be separated from contact with the second gear 75, the rack 40 moves upwards to drive the third gear 76 to rotate through meshing connection, the third gear 76 drives the gear shaft 78 and the fourth gear 79 to rotate, and the fourth gear 79 drives the second gear 75 to rotate through, the second gear 75 is connected with the generator shaft 15 through a flat key to rotate, so that the generator 14 rotates in the same direction to generate electricity, the original kinetic energy of the rotor in the generator 14 is prevented from being lost due to the fact that the generator 14 rotates reversely, the third piston 64 moves upwards to reset, airflow generated by the third piston 64 moving upwards is conveyed into the auxiliary piston cavity 82 through the air pipe 62, and the fourth piston 83, the fourth piston rod 80, the rotary disc 74 and the second gear 75 move rightwards to reset; after the set time, the three-position five-way valve 51 leads the air inlet pipe 53 to be communicated with the air passage pipe 44, part of the compressed air in the air storage box 22 is conveyed into the impeller 45 through the air inlet pipe 53, the three-position five-way valve 51 and the air passage pipe 44 to drive the second rotating shaft 46 and the brush 18 to rotate, the blades on the impeller 47 are cleaned, then the three-position five-way valve 51 leads the air inlet pipe 53 to be communicated with the air conveying pipe 25, the compressed air in the air storage box 22 is conveyed into the air cavity 28 through the air inlet pipe 53, the three-position five-way valve 51 and the air conveying pipe 25, and pushes the piston 27, the piston rod 30 and the scraper 58 to move to the right, so that the solid garbage on the filter screen 35 is conveyed to the right, the door 36 is opened by pushing the solid garbage, and then the solid garbage is pushed into the waste storage chamber 38 to be stored, thereby realize the solid waste in the automatic filtration waste water, avoid solid waste impact impeller 47 to can prolong power generating equipment life.

The invention has the beneficial effects that: the water storage power generation device can realize the delivery of quantitative water flow to the water turbine power generation mechanism by accumulating sewage, thereby ensuring that the water turbine can work within the working rotating speed range, further improving the water energy conversion efficiency of the water turbine and improving the utilization rate of water kinetic energy.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
