Therefore, in the tropical rain region, how to collect the power of rainwater falling, and use the potential energy of rainwater falling to generate electricity or in other ways is a problem to be solved, and therefore it is particularly necessary to develop a rainwater power collection and utilization system. SUMMARY

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Reference Figures 1-8This specific embodiment adopts the following technical solution: a rainwater dynamic harvesting and utilization system, including blades 1, columns 2, shielding areas 3, and a dynamic harvesting central shaft 4. The fourth quadrant area formed by the rotation of the blades 1 is designated as the shielding area 3, which is fixed by the columns 2. The blades 1 consist of flaps 101, a central column 102, and hinges 103. The dynamic harvesting central shaft 4 is connected to multiple blades 1. The blades 1 are fixedly connected to the dynamic harvesting central shaft 4 through the column ends 104 of the central column 102. Flaps 101 are connected to both sides of the central column 102 through hinges 103. The flaps 101 are installed on the central column 102 through multiple evenly distributed hinges 103. Two blades 1 are installed symmetrically on both sides of the central column 102 to form a foldable flap structure. The length of the flap 101 is shorter than the length of the central column 102. The flap 101 is installed on both sides of the outer end of the central column 102 away from the power collection central shaft 4, that is, the flap 101 is located at the outer end of the blade 1 to collect a larger torque relative to the power collection central shaft 4. The appropriate distance near the column end 104 is used to retain only the central column 102 to reduce the air resistance when the blade rotates upward.

[0020] In this specific embodiment, the flap 101 is designed as a concave shape resembling a winnowing basket. A water-storing groove 105 is formed on the flap 101. The water-storing groove 105 consists of a concave portion for collecting rainwater and an arc-shaped portion for facilitating drainage. The concave portion is located near the end of the flap 101 close to the power collection central axis 4. When the blade 1 is subjected to rainwater impact on its front side, the concave portion of the water-storing groove 105 can collect rainwater, thereby increasing the downward gravity and increasing the torque relative to the power collection central axis 4. The arc-shaped portion is located at the far end of the flap 101 away from the power collection central axis 4. When the blade 1 moves in the opposite direction, the rainwater can be completely poured out, reducing the weight of the blade. Specifically, in conjunction with Figure 8 The working principle of this system is as follows:

[0021] ① When blade 1 is in position I, blade 1 opens, rainwater impacts the opened flap 101, and water accumulates in the water storage groove 105. The accumulated water increases the weight of blade 1, promoting the downward movement of blade 1.

[0022] ② When blade 1 descends to position II, the front of blade 1 receives rain. At this time, the folding blade 101 bears the greatest impact force, the water accumulation in the water storage groove 105 is the greatest, the downward rotation kinetic energy of blade 1 is the greatest, and blade 1 continues to descend.

[0023] ③ When blade 1 is in position III, the water in the water storage groove 105 is gradually discharged, and blade 1 continues to rotate with the system;

[0024] ④ When blade 1 is in position IV, the water in the water storage groove 105 is completely drained, and blade 1 continues to rotate with the system;

[0025] ⑤ When blade 1 is in position V, the flap 101 bends downward under the action of gravity, and blade 1 rotates upward. Since the flap 101 is already in a bent state, the wind resistance of blade 1 is reduced, and blade 1 continues to rotate upward.

[0026] ⑥ When blade 1 rotates to position VI, flap 101 is completely folded. Figure 7 In this state, blade 1 has the lowest wind resistance and continues to move upward;

[0027] ⑦ When blade 1 is in position VII, this area is the shielding area 3, which can prevent rainwater from impacting the upward movement of blade 1, and blade 1 continues to rotate upward with the system;

[0028] ⑧ When blade 1 rotates to position VIII, blade 1 is in the state where flap 101 is about to open, and begins to withstand the impact of rainwater, and then proceeds to the next cycle, and so on.

[0029] This specific embodiment designs the blades as foldable flaps. When the front is subjected to rainwater impact, the flaps open to collect the rainwater's energy. The blades only fold and shield the system when rotating in the opposite direction, preventing rainwater impact and creating a positive bending moment around the central axis. This reduces the area perpendicular to the trajectory of motion, thus reducing air resistance. This collection and reuse system has a reasonable structural design and can collect the potential energy of rainwater falling during heavy rains in tropical regions for power generation or other uses. It provides low-cost electricity to the people in the installation area, benefiting the local population and possessing broad market application prospects.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
