Description
Technical Field
[0001] The utility model relates to the technical field of rainwater collection equipment, and particularly relates to a rainwater power collection and utilization system. Background Art
[0002] At present, in tropical regions, rainwater is relatively abundant. However, except for new energy forms such as wind power and solar power generation, no technology for generating electricity by using the potential energy of rainwater falling has been found. Therefore, in tropical rainy regions, how to collect the power of rainwater when it falls and use the potential energy of rainwater falling for power generation or in other ways is an urgent problem to be solved. Based on this, it is particularly necessary to develop a rainwater power collection and utilization system. Content of the Utility Model
[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a rainwater power collection and utilization system, with reasonable structural design, effectively recovering the power of rainwater when it falls, using the rainfall potential energy for power generation and doing work, reducing the power generation cost, benefiting the people, and having strong practicability and being easy to promote and use.
[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions: a rainwater power collection and utilization system includes blades, columns, a shielding area, and a power collection central shaft. The fourth quadrant area formed by the rotation of the blades is set as the shielding area, and this shielding area is fixed by being erected by columns; the blades are composed of folding pieces, a central column, and turning hinges. The power collection central shaft is connected with multiple blades. The blades are fixedly connected to the power collection central shaft through the column ends of the central column. Folding pieces are connected to both sides of the central column through turning hinges to form a foldable folding piece structure. The folding pieces are in a concave shape like a dustpan, and a water storage groove is formed.
[0005] Preferably, the length of the folding piece is shorter than the length of the central column. The folding pieces are installed on both outer ends of the central column far from the power collection central shaft to collect a relatively large torque relative to the central shaft and at the same time reduce air resistance.
[0006] Preferably, the folding pieces are installed on the central column through a plurality of evenly distributed turning hinges, and two blades are symmetrically installed on both sides of the central column.
[0007] Preferably, the water storage groove is composed of a concave part for collecting rainwater and an arc part for facilitating drainage. The concave part is arranged at the proximal end of the folding piece close to the power collection central shaft. When the front of the blade bears the impact of rainwater, the concave part of the water storage groove collects rainwater, increasing the downward gravity and increasing the torque relative to the power collection central shaft; the arc part is arranged at the distal end of the folding piece far from the power collection central shaft. When the blade moves in the reverse direction, the rainwater can be completely poured out to reduce the self-weight of the blade.
[0008] Advantages of the present utility model: This device can collect the potential energy of rainwater falling, generate electricity and do work by utilizing the rainfall potential energy, reduce the power generation cost, benefit the local people, and has high reliability and broad application prospects.

[0018] 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.
[0019] Refer to Figures 1-8, the present specific embodiment adopts the following technical solution: A rainwater power collection and utilization system includes a blade 1, a column 2, a shielding area 3, and a power collection central shaft 4. The fourth quadrant area formed by the rotation of the blade 1 is set as the shielding area 3, and the shielding area 3 is fixed by being erected on the column 2. The blade 1 is composed of a folding piece 101, a central column 102, and a turning hinge 103. The power collection central shaft 4 is connected with multiple blades 1. The blade 1 is fixedly connected to the power collection central shaft 4 through the column end 104 of the central column 102. Folding pieces 101 are connected to both sides of the central column 102 through turning hinges 103. The folding pieces 101 are installed on the central column 102 through multiple evenly distributed turning hinges 103. Two blades 1 are symmetrically installed on both sides of the central column 102, forming a foldable folding piece structure. The length of the folding piece 101 is shorter than the length of the central column 102. The folding pieces 101 are installed on both outer ends of the central column 102 far from the power collection central shaft 4, that is, the folding pieces 101 are located at the outer ends of the blade 1 to collect a relatively large torque relative to the power collection central shaft 4. Only the central column 102 is retained at an appropriate distance near the column end 104 to reduce the air resistance when the blade rotates upward.
[0020] In the present specific embodiment, the folding piece 101 is designed to be a concave shape like a dustpan. A water storage groove 105 is formed on the folding piece 101. The water storage groove 105 is composed of a concave part for collecting rainwater and an arc part for facilitating drainage. The concave part is arranged at the proximal end of the folding piece 101 close to the power collection central shaft 4. When the front of the blade 1 bears the impact of rainwater, the concave part of the water storage groove 105 can collect rainwater, thereby increasing the downward gravity and increasing the torque relative to the power collection central shaft 4. The arc part is arranged at the distal end of the folding piece 101 far from the power collection central shaft 4. When the blade 1 moves in the reverse direction, the rainwater can be completely poured out to reduce the self-weight of the blade. Specifically, in combination with Figure 8 , the working principle of this system is as follows:
[0021] ① When the blade 1 is in position I, the blade 1 is opened, rainwater impacts the opened folding piece 101, and water accumulates in the water storage groove 105. The accumulated water increases the weight of the blade 1 and promotes the downward movement of the blade 1;
[0022] ② When the blade 1 moves down to position II, the front of the blade 1 receives rain. At this time, the folding piece 101 bears the maximum impact force, the water accumulation in the water storage groove 105 is the largest, the downward rotation kinetic energy of the blade 1 is the largest, and the blade 1 continues to move downward;
[0023] ③ When the blade 1 is in position III, the accumulated water in the water storage groove 105 is gradually discharged, and the blade 1 continues to rotate with the system;
[0024] ④ When the blade 1 is in position IV, the accumulated water in the water storage groove 105 is completely discharged, and the blade 1 continues to rotate with the system;
[0025] ⑤When the blade 1 is in position V, the flap 101 bends downward under the action of gravity, and the blade 1 rotates upward. Since the flap 101 is already in a bent state, the wind resistance of the blade 1 is reduced at this time, and the blade 1 continues to rotate upward;
[0026] ⑥When the blade 1 rotates to position VI, the flap 101 is completely folded ( Figure 7 ), in this state, the wind resistance of the blade 1 is the smallest, and it continues to move upward;
[0027] ⑦When the blade 1 is in position VII, this area is the shielding area 3, which can prevent rainwater from impacting the upward movement of the blade 1, and the blade 1 continues to rotate upward with the system;
[0028] ⑧When the blade 1 rotates to position VIII, the blade 1 is in a state where the flap 101 is about to open, starts to bear the impact of rainwater, and enters the next cycle, and so on.
[0029] In this specific embodiment, the blade is designed as a foldable flap. When the front side bears the impact of rainwater, the flap opens to collect the rainwater power. When the blade only rotates reversely with the system, it folds and shields to avoid the impact of rainwater, forms a positive bending moment on the central axis, reduces the area perpendicular to the movement trajectory, and reduces air resistance. The structure design of this collection and reuse system is reasonable, can collect the potential energy of rainwater falling during heavy rain in tropical regions, and is used for power generation or other uses, bringing low-cost electricity to the people in the installation area, which is beneficial to the local people and has broad market application prospects.
