[0013] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Referring to Figures 1-3 , the following technical solutions are adopted in this specific embodiment: A rainwater power collection device, including a fan blade 1, a power collection central shaft 2, a limit slide rail 3, an upper cover of the fan blade return area 4 and a support structure 5. Multiple groups of fan blades 1 are provided, and each group of fan blades 1 crosses the power collection central shaft 2. The length of the power collection central shaft 2 is greater than the width of the fan blade 1. The fan blades 1 passing through the power collection central shaft 2 are evenly distributed in a crosswise manner. Each group of fan blades 1 is composed of a main rod 101, a rain-bearing impact surface 102, a moving wheel 103 and a baffle 104 perpendicular to the rain-bearing impact surface 102. A group of rain-bearing impact surfaces 102 and baffles 104 are installed on both sides of the main rod 101. An included angle between the rain-bearing impact surface 102 and the baffle 104 forms a rainwater storage area. Moving wheels 103 are also installed at both ends of the main rod 101, and the moving wheels 103 cooperate with the limit slide rail 3; both sides of the power collection central shaft 2 are installed on the support structure 5. A hole 6 for passing through the main rod 101 is provided on the power collection central shaft 2 in the vertical direction, and power output areas 7 are symmetrically arranged outside the hole 6; An upper cover 4 of the fan blade return area is erected in the fourth quadrant area formed by the rotation of the fan blade 1.

[0015] It should be noted that the power output area 7 is connected to an external power system through structures such as gears or belts to output the collected power outward.

[0016] In this specific embodiment, the fan blade 1 reciprocates along the hole 6 reserved on the power collection central shaft 2 through the main rod 101. Since the fan blade 1 may rotate axially along the main rod 101 when there is only one main rod, in order to prevent such a situation, at least two main rods 101 need to be provided. Figure 1In the structure of the collection device shown, there are two sets of fan blades 1, and each set of fan blades 1 perpendicularly penetrates the power collection central axis 2 and is arranged in a cross shape.

[0017] In this specific embodiment, a upper cover 4 of the fan blade return area is also added above the reverse movement area of the fan blade 1 to avoid torque cancellation. At the same time, a limit slide rail 3 is used to adjust the length of the fan blade arm, so that the arm length in the power receiving area is lengthened and the arm length in the non-power receiving area is reduced to obtain a greater torque and reduce the canceling torque. In addition, the device strengthens the bearing capacity at the outer openings on both sides of the hole 6 reserved on the power collection central axis 2, and can also extend appropriately to both sides along the main rod 101 of the fan blade and perform bearing reinforcement to improve the operation stability of the device. Specifically, the operation principle of this device is as follows( Figure 3 ):

[0018] (1) When the fan blade 1 is in position I, the upper end of the fan blade 1 is in the state of being impacted by raindrops. The rain receiving impact surface 102 and the upward-facing surface of the baffle 104 are both impacted by the rain. The fan blade 1 receives a downward rotation torque. At the same time, there is rainwater stored in the angle between the rain receiving impact surface 102 and the baffle 104, increasing the downward rotation torque of the fan blade 1.

[0019] (2) When the fan blade 1 is in position II, the fan blade 1 is perpendicular to the rain impact and bears the maximum rain impact force.

[0020] (3) When the fan blade 1 is in position III, the rainwater stored in the fan blade 1 has been poured out. At this time, the fan blade has reached the position of the limit slide rail 3, and the moving wheel 103 at its end contacts the limit slide rail 3.

[0021] (4) When the fan blade 1 is in position IV, under the action of the limit slide rail 3, while the fan blade group rotates with the system, the whole fan blade group moves to the opposite side of the power collection central axis 2, making the fan blade cantilever on the opposite side longer and the fan blade cantilever on this side shorter.

[0022] (5) When the fan blade 1 is in position V, the cantilever on this side of the fan blade reaches the shortest. The fan blade on the opposite side has reached position I, and there is an upper cover 4 of the fan blade return area above the fan blade on this side, so that the fan blade is not impacted by rainwater.

[0023] (6) When the fan blade 1 is in position VI, the fan blade keeps the shortest on this side and continues to move upward. The fan blade on the opposite side has reached position II, and the fan blade is not impacted by rainwater.

[0024] (7) When the fan blade 1 is in position VII, at this time, the fan blade on the opposite side is in position III, the opposite side is about to gradually shorten, and this side is about to gradually lengthen.

[0025] (8) When the fan blade 1 is in position VIII, the cantilever of the fan blade on this side continues to lengthen, and the fan blade on the opposite side is in position V, and the cantilever gradually shortens.

[0026] (9) The power collection central shaft 2 collects the power of rainwater during the rotation of the fan blade 1 and outputs the power through the power output area 7 for power generation or direct work.

[0027] This specific embodiment can collect the potential energy of the falling rainwater during heavy rain in southern China or tropical regions, and is used for direct work, power generation, or other utilization methods. It is a considerable green energy source, which is beneficial to the local people and has broad market application prospects.
