[0026] The opening of the collecting container 9 is a slope.

[0027] The vibrating plate 10 is horizontally distributed without external force.

[0028] The working process of the rainwater power generation system which combines the vibration and the rotation of the turbine according to the embodiment of the utility model is as follows: when it rains, the rainwater will first fall into the 36 primary rainwater collecting mechanisms, specifically, the rainwater will enter the primary collecting groove 4 in each primary rainwater collecting mechanism, under the action of the funnel-shaped primary collecting groove 4, the rainwater will be collected to the bottom of the primary collecting groove 4 and flow out through the primary drain pipe 5,

[0029] After the rainwater flows out from the primary drain pipe 5, the rainwater will first impact the impeller 6, specifically, the rainwater will impact the collecting container 9 arranged on the impeller 6, part of the rainwater will directly enter the inner cavity of the collecting container 9, and the other part of the rainwater will be broken and scattered under the action of the collecting container 9 and then drop to the vibrating plate 10 below, since the axis direction of the primary drain pipe 5 is along the tangent direction of the circle formed by the plurality of connecting rods 8, the impeller 6 will rotate under the impact of the water flow, in the process of rotation, the part of the rainwater in the collecting container 9 will also automatically flow out after rotating to a certain angle and then drop to the vibrating plate 10 below, that is, under the action of the impeller 6, the water flow will be fully scattered;

[0030] The free end of the vibrating plate 10 is provided with a first magnet 11, and the support frame 1 is further provided with a second magnet 12 matched with the first magnet 11. Under the repulsion of the two magnets, the vibrating plate 10 can keep a horizontal state when no external force is applied, and can also return to the initial state after being impacted by rain, so as to make the vibrating plate 10 continuously vibrate for a long time, thereby improving the power generation efficiency.

[0031] Since the vibrating plate 10 has a cantilever structure, it will vibrate after being impacted, and the piezoelectric film layer arranged thereon will generate an electric current due to the vibration. The electric current generated by the piezoelectric film layer in the first rainwater collecting mechanism is processed into stable direct current by the processing circuit and then input into the storage battery for storage.

[0032] Rainwater will flow downward through the gap between the vibrating plate 10 and the support frame 1 into the secondary rainwater collecting mechanism. After entering the funnel-shaped secondary collecting groove 13, the rainwater flows into the top water turbine 15 through the secondary drain pipe 14. When the rainwater flows through the top water turbine 15, it drives the impeller inside to rotate. The electric current generated by the top water turbine 15 is processed into stable direct current by the processing circuit and then input into the storage battery for storage.

[0033] The rainwater in the four secondary rainwater collecting mechanisms will finally enter the funnel-shaped tertiary collecting groove 16 and flow downward through the total drain pipe 2 to the ground water turbine 3 arranged at the bottom of the building. When the rainwater flows through the ground water turbine 3, it drives the impeller inside to rotate. The electric current generated by the ground water turbine 3 is processed into stable direct current by the processing circuit and then input into the storage battery for storage. The outlet end of the ground water turbine 3 is connected with the urban drainage system to discharge the rainwater into the sewer.

[0034] The rainwater power generation system utilizes the rainwater to impact the vibrating plate, converts the impact potential energy into electric energy through the piezoelectric film layer, and converts the gravitational potential energy of the rainwater into electric energy through the secondary rainwater collecting mechanism and the tertiary rainwater collecting mechanism. Through the three-stage energy conversion, rainwater power generation is realized.
