Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting equipment technology, specifically to a rainwater dynamic harvesting device. Background Technology

[0002] Currently, green energy is highly favored, with wind power and photovoltaics developing rapidly. However, in southern China and tropical regions of the world, rainfall is abundant. Apart from new energy sources such as wind and solar power, no technology has yet been found to utilize the potential energy of falling rainwater for power generation. Therefore, in tropical rainy regions, how to collect the power of falling rainwater and directly use the potential energy of rapid, heavy rainfall for power generation or other purposes is an urgent problem to be solved. Based on this, developing a rainwater dynamics harvesting device is particularly necessary. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a rainwater dynamic harvesting device with a simple structure and reasonable design. It can effectively recover the power of rainwater during rainfall, utilize the potential energy of rainfall to generate electricity and perform work, reduce power generation costs, benefit the public, and is highly practical and easy to promote and use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rainwater power harvesting device, comprising fan blades, a power harvesting central shaft, a limiting slide rail, an upper cover for the fan blade return area, and a support structure. Multiple sets of fan blades are provided, each set traversing the power harvesting central shaft. The fan blades traversing the power harvesting central shaft are evenly distributed in a crisscross pattern. Each set of fan blades consists of a main rod, a rain-receiving impact surface, a traveling wheel, and a baffle perpendicular to the rain-receiving impact surface. A set of rain-receiving impact surfaces and baffles are installed on both sides of the main rod, and the angle between the rain-receiving impact surface and the baffle forms a rainwater storage area. Traveling wheels are also installed at both ends of the main rod, and the traveling wheels cooperate with the limiting slide rail. The power harvesting central shaft is mounted on the support structure on both sides. Holes for the main rod are provided vertically on the power harvesting central shaft, and power output areas are symmetrically arranged outside the holes. The fourth quadrant area formed by the rotation of the fan blades is covered with an upper cover for the fan blade return area.

[0005] Preferably, the fan blades are provided in two sets, with each set of fan blades passing perpendicularly through the power collection central axis and arranged in a cross pattern; the fan blades reciprocate along the pre-reserved holes on the power collection central axis via the main rod.

[0006] Preferably, the length of the power collection central shaft is greater than the width of the fan blades.

[0007] Preferably, the limiting slide rail is an arc-shaped slide rail. By contacting the traveling wheel of the fan blade with the limiting slide rail, the length of the fan blade arm is adjusted, so that the arm length of the power receiving area is increased and the arm length of the non-power receiving area is reduced, thereby obtaining greater torque.

[0008] Preferably, the power output area is connected to an external power system via a gear or belt structure to output the collected power to the outside.

[0012] Figure 2 This is a schematic diagram of the installation of the fan blades and the power collection central shaft of the present invention;

[0014] 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.

[0015] Reference Figure 1-3 The specific embodiment adopts the following technical solution: a rainwater dynamic harvesting device, including fan blades 1, a dynamic harvesting central shaft 2, a limiting slide rail 3, an upper cover 4 for the fan blade return area, and a support structure 5. Multiple sets of fan blades 1 are provided, each set of fan blades 1 traversing the dynamic harvesting central shaft 2. The length of the dynamic harvesting central shaft 2 is greater than the width of the fan blades 1. The fan blades 1 traversing the dynamic harvesting central shaft 2 are evenly distributed in a crisscross pattern. Each set of fan blades 1 consists of a main rod 101, a rain-receiving impact surface 102, a traveling wheel 103, and a baffle 104 perpendicular to the rain-receiving impact surface 102. The main rod 1... Both sides of the main rod 101 are equipped with a set of rain-receiving impact surfaces 102 and baffles 104. The included angle between the rain-receiving impact surfaces 102 and baffles 104 forms a rainwater storage area. Both ends of the main rod 101 are also equipped with driving wheels 103, which cooperate with the limiting slide rails 3. The two sides of the power collection center shaft 2 are mounted on the support structure 5. The power collection center shaft 2 has holes 6 through the main rod 101 in a vertical direction. The power output area 7 is symmetrically arranged outside the holes 6. The fourth quadrant area formed by the rotation of the fan blade 1 is equipped with an upper cover 4 for the fan blade return area.

[0016] It is worth noting that the power output zone 7 is connected to an external power system via a structure such as gears or belts to output the collected power to the outside.

[0017] In this specific embodiment, the fan blade 1 reciprocates along the pre-drilled hole 6 on the power collection center shaft 2 via the main rod 101. Since the fan blade 1 may rotate axially along the main rod 101 when there is only one main rod, at least two main rods 101 are required to prevent this. Figure 1 The collection device structure shown has two sets of fan blades 1, each set of fan blades 1 passing perpendicularly through the power collection central axis 2, arranged in a cross shape.

[0018] This specific embodiment also adds a fan blade return zone upper cover 4 above the fan blade 1 reverse motion zone to prevent torque cancellation. Simultaneously, a limiting slide rail 3 is used to adjust the fan blade arm length, increasing the arm length in the power receiving zone and decreasing the arm length in the non-power receiving zone to obtain greater torque and reduce cancellation torque. Furthermore, the device reinforces the load-bearing capacity at the outer openings of the holes 6 pre-drilled on the power collection center shaft 2, and can also appropriately extend the fan blade main rod 101 to both sides for load-bearing reinforcement, improving the device's operational stability. Specifically, the operating principle of this device is as follows ( Figure 3 ):

[0019] (1) When the fan blade 1 is in position I, the upper end of the fan blade 1 is under raindrop impact. The rain-receiving impact surface 102 and the upward-facing surface of the baffle 104 are both impacted by rain. The fan blade 1 receives a downward rotation torque. At the same time, rainwater is stored in the angle between the rain-receiving impact surface 102 and the baffle 104, which increases the downward rotation torque of the fan blade 1.

[0020] (2) When the fan blade 1 is in position II, the fan blade 1 is perpendicular to the rainwater impact and bears the maximum rainwater impact force.

[0021] (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 is in contact with the limit slide rail 3.

[0022] (4) When the fan blade 1 is in position IV, under the action of the limit slide rail 3, the fan blade 1 moves as a whole to the opposite side of the power collection center shaft 2 while rotating with the system, making the fan blade cantilever on the opposite side longer and the fan blade cantilever on this side shorter.

[0023] (5) When the fan blade 1 is in position V, the cantilever on this side of the fan blade is at its shortest, the fan blade on the opposite side has reached position I, and there is a fan blade return area upper cover 4 above the fan blade on this side, so that the fan blade is not affected by rain.

[0024] (6) When the fan blade 1 is in position VI, the fan blade continues to move upward while keeping the shortest side. The fan blade on the opposite side has reached position II and is not affected by rainwater.

[0025] (7) When fan blade 1 is in position VII, the opposite fan blade is in position III. The opposite side will gradually shorten and the local side will gradually lengthen.

[0026] (8) When fan blade 1 is in position VIII, the cantilever of the fan blade on this side continues to lengthen, while the fan blade on the opposite side is in position V and the cantilever gradually shortens.

[0027] (9) The power collection center 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 to generate electricity or do work directly.

[0028] This specific implementation method can collect the potential energy of rainwater falling during heavy rain in southern or tropical regions of my country, and use it for direct work and power generation, or for other purposes. It is a considerable green energy source that benefits local people and has broad market application prospects.
