Abstract
Description
Technical Field
[0001] This invention relates to the field of vertical axis wind turbine technology, specifically a vertical axis axial magnetic wind turbine. Background Technology
[0002] Vertical axis wind turbines do not need to be aligned with the wind when the wind direction changes, which is a major advantage over horizontal axis wind turbines. This not only simplifies the structural design but also reduces the gyroscopic force on the rotor when it is aligned with the wind.
[0003] Currently, vertical axis wind turbines all use traditional radial magnetic field motors. This type of generator is large in size, not compact in structure, and has poor heat dissipation. In addition, when the vertical axis wind turbine rotates, the blades rotating against the wind direction are subject to wind resistance, which affects the rotation of the vertical axis wind turbine blades and is inconvenient for users.
[0004] To address the aforementioned issues, an improved vertical-axis axial magnetic ventilator is now designed. Summary of the Invention

[0009] As a further embodiment of the present invention: the windbreak mechanism includes an arc-shaped windbreak plate, the arc length of which is one-quarter of the total circumference. The arc-shaped windbreak plate is vertically disposed on the side of the blade away from the rotating frame.

[0010] As a further embodiment of the present invention: the air passage component includes a blocking plate, the arc-shaped windbreak plate has several first openings horizontally provided to facilitate the passage of wind, the blocking plate is vertically slidably connected to the inner wall of the arc-shaped windbreak plate, the blocking plate has several second openings that cooperate with the first openings, when the second openings are misaligned with the first openings, the blocking plate blocks the first openings, several electric telescopic rods are vertically installed on the upper side wall of the fixed plate, the output end of the electric telescopic rods is equipped with a moving ring, the lower end of the blocking plate passes through the arc-shaped windbreak plate and is rotatably connected to the upper end of the moving ring by ball bearings, and the mounting plate is provided with a detection and control component for controlling the opening and closing of the first openings.
[0011] As a further embodiment of the present invention: the detection and control component includes a controller, which is mounted on the upper end of a fixed plate. A fixed frame is mounted on the upper end of the mounting plate on the side away from the wind vane. A rotating shaft is horizontally arranged inside the fixed frame. A support plate for supporting the rotating shaft is rotatably connected to the side wall of the rotating shaft. Both ends of the support plate are mounted on the inner wall of the fixed frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] This invention generates electricity through an axial magnetic flux power generation structure inside a rotating frame, resulting in a compact structure, high power density, and good heat dissipation.
[0019] This invention utilizes the wind-driven rotation of a wind vane, which in turn causes an arc-shaped wind deflector to rotate. This allows the arc-shaped wind deflector to block one side of the rotating frame, facilitating wind to blow the blades from the unfolded side. This avoids wind resistance in the blades' rotation direction and improves the blades' rotation efficiency.
[0020] This invention determines whether the arc-shaped wind deflector needs to be rotated and adjusted by judging the rotational speed of the fan blades being blown by the wind. When the arc-shaped wind deflector is rotated and adjusted, the sealing plate is moved by an electric telescopic rod to align the first opening and the second opening, so that the wind can pass through, reducing the resistance to the rotation of the arc-shaped wind deflector and facilitating the rotational adjustment of the arc-shaped wind deflector.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Please see Figures 1-6 In this embodiment of the invention, a vertical axis axial magnetic field power generator includes a column 1 and several blades 7. A base 2 is installed at the lower end of the column 1. A rotating frame 6 is rotatably connected to the upper end of the side wall of the column 1. Several blades 7 are arranged in a circular array around the rotating frame 6. A support rod 8 is horizontally installed on the side wall of the blades 7 near the rotating frame 6. The end of the support rod 8 away from the blades 7 is installed on the side wall of the rotating frame 6. A fixing plate 18 is horizontally installed on the side wall of the column 1 below the rotating frame 6. A power generation mechanism for generating electricity by rotating the rotating frame 6 is provided inside the rotating frame 6. A windbreak mechanism for directing wind to one side of the blades 7 is provided above the fixing plate 18.
[0030] The power generation mechanism includes a base plate 26, which is horizontally mounted on the side wall of the column 1 inside the rotating frame 6. A stator yoke 25 is mounted on the upper end of the base plate 26. Several stator coils 24 are mounted in a circular array on the upper end of the stator yoke 25. Mounting frames 29 are mounted on the inner walls of the rotating frame 6 above and below the base plate 26. Several permanent magnet poles 27 are mounted in a circular array on the end of the mounting frame 29 near the base plate 26. There is an even number of permanent magnet poles 27, and the polarities of two adjacent permanent magnet poles 27 are opposite. A rotor yoke 28 is mounted between the permanent magnet poles 27 and the mounting frames 29. The permanent magnet poles 27 on two mounting frames 29 on the same vertical line have the same polarity.
[0031] When in use, the wind blows the blades 7, which in turn drive the rotating frame 6 to rotate via the support rod 8. The rotating frame 6 drives the mounting frame 29 to rotate, which in turn drives the permanent magnet pole 27 to rotate, causing the stator coil 24 to cut the magnetic field lines. This causes the stator coil 24 to generate an induced current, which is then output through an external wire.
[0032] The windbreak mechanism includes an arc-shaped windbreak plate 14, the arc length of which is one-quarter of the total circumference. The arc-shaped windbreak plate 14 is vertically arranged on the side of the blade 7 away from the rotating frame 6. A connecting rod 13 is horizontally installed on the upper end of the side wall of the arc-shaped windbreak plate 14 near the rotating frame 6. A rotating sleeve 3 is installed on the end of the connecting rod 13 away from the arc-shaped windbreak plate 14. The rotating sleeve 3 is rotatably connected to the side walls of the columns 1 above and below the rotating frame 6. An installation plate 10 is horizontally installed on the upper end of the rotating sleeve 3 above the rotating frame 6. A wind vane 9 for guiding according to the wind direction is installed on one side of the upper end of the installation plate 10. The diameter of the outermost part of the installation plate 10 is parallel to that of the arc-shaped windbreak plate 14. A wind-passing component is provided on the arc-shaped windbreak plate 14 to facilitate the rotation and adjustment of the arc-shaped windbreak plate 14.
[0033] When in use, the wind blows onto the wind vane 9, which causes the mounting plate 10 to rotate. The mounting plate 10 then causes the rotating sleeve 3 to rotate, which in turn causes the connecting rod 13 to rotate. The connecting rod 13 then causes the arc-shaped wind deflector 14 to rotate, thus blocking the wind from one side of the rotating frame 6 and directing the wind towards the unblocked blades 7, thereby causing the blades 7 to rotate.
[0034] The air passage assembly includes a blocking plate 16. The arc-shaped windbreak plate 14 has several first openings 15 horizontally formed to facilitate air passage. The blocking plate 16 is vertically slidably connected to the inner wall of the arc-shaped windbreak plate 14. The blocking plate 16 has several second openings 19 that cooperate with the first openings 15. When the second openings 19 and the first openings 15 are misaligned, the blocking plate 16 blocks the first openings 15. Several electric telescopic rods 4 are vertically installed on the upper side wall of the fixing plate 18. A moving ring 5 is installed at the output end of the electric telescopic rod 4. The lower end of the blocking plate 16 passes through the arc-shaped windbreak plate 14 and is rotatably connected to the upper end of the moving ring 5 by ball bearings. The mounting plate 10 is provided with a detection and control assembly for controlling the opening and closing of the first openings 15.
[0035] The detection and control assembly includes a controller 17, which is mounted on the upper end of a fixed plate 18. A fixed frame 11 is mounted on the upper end of the mounting plate 10 away from the wind vane 9. A rotating shaft 23 is horizontally arranged inside the fixed frame 11. A support plate 20 for supporting the rotating shaft 23 is rotatably connected to the side wall of the rotating shaft 23. Both ends of the support plate 20 are mounted on the inner wall of the fixed frame 11. A fan blade 22 is mounted on the side wall of one end of the rotating shaft 23. A speed sensor 21 for measuring the rotation speed of the rotating shaft 23 is mounted on the inner wall of the fixed frame 11 on the side of the support plate 20 away from the fan blade 22. A conical guide block 12 is mounted on the end of the fixed frame 11 away from the wind vane 9.
[0036] During use, the wind blows onto the wind vane 9 and also onto the fan blades 22 inside the fixed frame 11, causing the fan blades 22 to rotate. The fan blades 22 drive the rotating shaft 23 to rotate. The speed sensor 21 measures the rotation speed of the speed sensor 21 in real time and wirelessly transmits the data to the controller 17. The controller 17 compares and analyzes the rotation speed. When the rotation speed is greater than the set value, the controller 17 controls the electric telescopic rod 4 to start. The output end of the electric telescopic rod 4 pushes the moving ring 5 to move. The moving ring 5 pushes the sealing plate 16 to move. The sealing plate 16 drives the second opening 19 to move and aligns the second opening 19 with the first opening 15, making it easier for the wind to pass through, thereby facilitating the rotation of the arc-shaped wind deflector 14.
[0037] When the wind vane 9 is aligned with the wind direction, the fan blade 22 is not blown by the wind or rotates at a low speed, with the rotation speed being less than the set value. The controller 17 controls the electric telescopic rod 4 to start, and the output end of the electric telescopic rod 4 drives the moving ring 5 to move. Under the action of gravity, the sealing plate 16 moves downward, and the sealing plate 16 drives the second opening 19 to move, causing the second opening 19 to be misaligned with the first opening 15. The sealing plate 16 then seals the first opening 15.
[0038] Working principle of a vertical axis axial magnetic pneumatic generator:
[0039] In use, the wind blows onto the fan blades 22 inside the wind vane 9 and the fixed frame 11, causing the fan blades 22 to rotate. The fan blades 22 drive the rotating shaft 23 to rotate. The speed sensor 21 measures the rotation speed of the speed sensor 21 in real time and wirelessly transmits the data information to the controller 17. The controller 17 compares and analyzes the rotation speed. When the rotation speed is greater than the set value, the controller 17 controls the electric telescopic rod 4 to start. The output end of the electric telescopic rod 4 pushes the moving ring 5 to move. The moving ring 5 pushes the sealing plate 16 to move. The sealing plate 16 drives the second opening 19 to move and aligns the second opening 19 with the first opening 15, making it easier for the wind to pass through. This facilitates the rotation of the arc-shaped wind deflector 14. The wind vane 9 drives the mounting plate 10 to rotate. The mounting plate 10 drives the rotating sleeve 3 to rotate. The rotating sleeve 3 drives the connecting rod 13 to rotate. The connecting rod 13 drives the arc-shaped wind deflector 14 to rotate, so that the arc-shaped wind deflector 14 blocks the wind on one side of the rotating frame 6, causing the wind to blow onto the unblocked blades 7, thereby causing the blades 7 to rotate.
[0040] When the wind vane 9 is aligned with the wind direction, the fan blade 22 is not blown by the wind or rotates at a low speed, with the rotation speed being less than the set value. The controller 17 controls the electric telescopic rod 4 to start, and the output end of the electric telescopic rod 4 drives the moving ring 5 to move. Under the action of gravity, the sealing plate 16 moves downward, and the sealing plate 16 drives the second opening 19 to move, causing the second opening 19 to be misaligned with the first opening 15. The sealing plate 16 then seals the first opening 15.
[0041] The wind blows the blade 7, which drives the rotating frame 6 to rotate via the support rod 8. The rotating frame 6 drives the mounting frame 29 to rotate, and the mounting frame 29 drives the permanent magnet pole 27 to rotate, causing the stator coil 24 to cut the magnetic field lines, thereby generating an induced current in the stator coil 24, which is then output through an external wire.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
