Description

Technical Field

[0001] The utility model belongs to the technical field of vertical axis wind power generation and relates to a vertical axis wind power generation device. Background Art

[0002] Currently, wind power generation on the market primarily includes horizontal wind turbines and vertical-axis wind turbines. Small vertical-axis wind turbines primarily consist of a central column and a blade rack rotatably connected to the column, with multiple blades on the blade rack. Larger vertical-axis wind turbines, however, require no central column for support. Instead, multiple support columns are installed around the blade rack, interconnected to support the rotation of the blade rack. The bottom of the blade rack drives a power shaft, which connects to the rotor of a generator or the output of a gearbox driven by the blade rack, increasing its speed and driving the motor's rotor. While this approach allows for large-scale vertical-axis wind power generation, the multiple columns distributed around the blade rack (typically six or more large columns, with reinforcing ribs between adjacent columns) still create resistance to air flow, affecting wind energy utilization and resulting in poor power generation.

[0034] A first end portion 16 is provided on the inner side of the bottom of the blade frame 10, and a plurality of buffer members 17 are provided on the inner side of the first end portion 16. When the movement direction of the blade frame 10 is the same as the direction of the wind, the lower frame 14 abuts against the buffer member 17. When the movement direction of the blade frame 10 is opposite to the direction of the wind, the lower frame 14 and the buffer member 17 are separated.

[0035] The inner wall of the blade frame 10 is also provided with a second end portion 18, and the second end portion 18 is located on the side of the rotating shaft 11. When the upper frame 12 is flipped to a horizontal state, the bottom of the upper frame 12 abuts against the top of the second end portion 18. A first tensioning cable 19 is provided on the inner wall of the upper frame 12, and both ends of the first tensioning cable 19 are connected to the upper frame 12, and the middle part is connected to the first wind-receiving part 13. A second tensioning cable 20 is provided on the inner wall of the lower frame 14, and both ends of the second tensioning cable 20 are connected to the lower frame 14, and the middle part is connected to the second wind-receiving part 15.

[0036] A plurality of fine-tuning holes 21 are formed through the top of the upper frame 12 , and a receiving hole with a diameter larger than that of the fine-tuning hole 21 is formed at both ends of the fine-tuning hole 21 ;

[0037] It also includes a first fine-tuning disk 22 and a second fine-tuning disk 23, which are respectively matched with the two accommodating holes. A connecting screw 24 is provided on the side of the first fine-tuning disk 22, and a connecting tube 25 is provided on the side of the second fine-tuning disk 23. The inner wall of the connecting tube 25 is threadedly connected to the connecting screw 24, and the outer wall is fitted into the fine-tuning hole 21. A plurality of glue injection grooves 26 are provided on the periphery of the first fine-tuning disk 22 and the second fine-tuning disk 23.

[0038] The vertical axis wind turbine generator provided by the present invention is a relatively large vertical axis wind turbine generator, and the blade frame 2 is supported by the support column 1 in the middle, and the top of the support column 1 is provided with a stabilizing frame 3 and a stabilizing member 4, and the bottom of the stabilizing member 4 is connected to the ground (for example, a concrete block is pre-buried in the ground, and the stabilizing member 4 is fixedly connected to the concrete block). In this way, the stability of the support column 1 in the horizontal direction can be ensured by the stabilizing member 4 and the stabilizing frame 3, so that the support column 1 only needs to bear the mass of the blade frame 2, etc., so that large-scale vertical axis wind power generation can be realized; at the same time, since there are only stabilizing members 4 (such as steel cables, etc.) around the blade frame 2, the resistance to wind is small, so that the wind power generation effect is better, and the cost of the power generation device is also lower.

[0039] The stabilizing member 4 is tilted, which provides better support and pulling effects on the stabilizing frame 3. Furthermore, multiple stabilizing members 4 are positioned at the end of the stabilizing frame 3 to simultaneously pull, further enhancing the stability of the stabilizing frame 3. The bottom frame 3a, top frame 3b, and reinforcement 5 of the stabilizing frame 3 fully ensure the structural strength of the stabilizing frame 3 and provide better support for the support column 1. The overall quality control is kept at a low level, which reduces production costs and simplifies transportation and installation.

[0040] The entire blade frame 2 and the transmission sleeve 7 are rotatably connected to the support column 1 through the first support bearing 6 and the second support bearing 8 (both of which are preferably large tapered roller bearings), and the blade frame 2 transmits kinetic energy through the transmission sleeve 7; when the blade frame 2 rotates, the transmission sleeve 7 is synchronously driven to rotate, which results in a slower speed of the transmission sleeve 7, but a large force; while the transmission sleeve 7 rotates, the active tooth body 9 on its outer wall drives the passive gear to rotate, and the passive gear drives the gearbox (or transmission, preferably a planetary gearbox or gear transmission purchased directly on the market to increase the speed), and then the gearbox drives the rotor of the generator to rotate and generate electricity.

[0041] When the blade frame 10 rotates to the side blown by the wind, the second wind receiving member 15 with a larger area is subjected to a greater wind pressure, and the side of the lower frame 14 is in contact with the buffer member 17 (which plays a protective role). At the same time, the upper frame 12 is kept in a vertical state. In this way, the first wind receiving member 13 and the second wind receiving member 15 can be better affected by the air flow and generate a greater wind resistance thrust. Then, when the blade frame 10 rotates to the other side blown by the wind and returns, since the second wind receiving member 15 is subjected to a greater wind force, the lower frame 14 is flipped upward, driving the upper frame 12 to rotate downward to be open or horizontal. At this time, the air can pass through the blade frame 10 better and generate less resistance. In this way, no matter which direction the air blows from, the blade frame 2 can be rotated in one direction and drive the transmission sleeve 7 to rotate and generate electricity.

[0042] The upper frame 12 is smaller than the lower frame 14, but its mass is greater. This allows the upper frame 12 (with the first wind-receiving member 13 and the first tensioning cable 19) and the lower frame 14 (with the second wind-receiving member 15 and the second tensioning cable 20) to achieve mass balance or near-balance around the rotation axis 11, thereby minimizing the rotational resistance of the entire blade frame 10. This allows the blade frame 10 to rotate nearly horizontally during its return stroke when wind speeds are high, thereby minimizing resistance. The second end stop 18 acts as a limiter for the lower frame 14, preventing the upper frame 12 from rotating excessively upward when wind speeds are high.

[0043] The first tensioning cable 19 and the second tensioning cable 20 can improve the use stability and extend the service life of the first wind receiving part 13 and the second wind receiving part 15, and the first wind receiving part 13 and the second wind receiving part 15 are preferably made of fiber cloth material, so that they are lighter in weight and have a longer service life.

[0044] In the actual production process, it is difficult to make the mass of the upper frame 12 (with the first wind receiving part 13, the first tensioning cable 19) and the lower frame 14 (with the second wind receiving part 15, the second tensioning cable 20) completely balanced with the rotation axis 11 as the axis (usually the upper frame 14 is slightly lighter). At this time, after the upper frame 12 (with the first wind receiving part 13, the first tensioning cable 19) and the lower frame 14 (with the second wind receiving part 15, the second tensioning cable 20) are assembled, if they are balanced, no fine-tuning is required. However, if they are unbalanced, fine-tuning can be performed through the first fine-tuning disk 22 and the second fine-tuning disk 23, which act as a counterweight. That is, they can be used for the upper frame 12 according to actual conditions, and the number of them to be used can also be selected according to actual conditions, so that the upper frame 12 (with the first wind receiving part 13, the first tensioning cable 19) and the lower frame 14 (with the second wind receiving part 15, the second tensioning cable 20) are balanced or as close to balanced as possible.

[0045] When in use, just insert the connecting tube 25 into the fine-tuning hole 21, then thread the connecting screw 24 to the connecting tube 25 until the first fine-tuning disk 22 and the second fine-tuning disk 23 are located in the two fine-tuning holes 21, and finally inject glue through the glue injection groove 26 to fully fix the first fine-tuning disk 22 and the second fine-tuning disk 23 to the blade frame 10.

[0046] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
