Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, specifically to a modular integrated new energy wind power generation device. Background Technology

[0002] Wind power, as a clean and renewable energy technology, is playing an increasingly important role in the global energy structure. Vertical axis wind turbines have attracted widespread attention in distributed generation, urban environments, and small and medium-sized wind power applications due to their advantages such as not requiring wind-catching devices, compact structure, and convenient maintenance. Among them, drag-type vertical axis wind turbines that capture wind energy using curved blades have the characteristics of good self-starting performance and can operate at low wind speeds, making them suitable for complex environments with frequent changes in wind speed and direction.

[0003] However, when dealing with extreme wind conditions, existing vertical axis wind power generation devices mainly rely on mechanical or electromagnetic braking to force the turbines to stop when the wind speed exceeds the design safety threshold. However, the braking system is subjected to huge wind load torque for a long time, which can easily lead to wear, overheating or even failure of the braking components. Furthermore, the blades and shafts are still subjected to large aerodynamic loads under the continuous action of strong winds, which poses safety hazards such as structural fatigue and overspeeding. It is difficult to achieve truly reliable wind unloading protection. Summary of the Invention

[0026] 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.

[0027] like Figures 1-6 As shown, the present invention provides a technical solution:

[0028] A modular integrated new energy wind power generation device includes a base 1, with a transmission shell 2 fixedly connected to the middle of its top. A bottom shell 3 is fixedly connected to one side of the transmission shell 2. A rotating mechanism is provided at the top of the bottom shell 3. The rotating mechanism includes a hollow shaft 6 rotatably connected to the middle of the bottom shell 3 via bearings, and a column 7 fixedly connected to the middle of the top of the hollow shaft 6. Several guide frames 8 are evenly distributed and fixedly connected to the upper and lower ends of the side wall of the column 7. A drive disk 9 is rotatably arranged at the upper and lower ends inside the column 7. A synchronous shaft 10 is fixedly connected between the middle of two drive disks 9. Several oblique elongated holes 11 are evenly distributed on the drive disk 9 along the circumference. The rotating mechanism also includes a... The column 7 has several blades 12 on its outer side, and rotating shafts 13 fixedly connected to the upper and lower ends of the blades 12. The ends of the upper and lower rotating shafts 13 away from the blades 12 extend into the interior of the guide frame 8 and are fixedly connected to gears 14. A rack 15 that meshes with the gears 14 is arranged laterally in the middle of the inner side of the guide frame 8. Guide grooves that slide with the rack 15 are opened through both ends of the guide frame 8. A drive rod 16 that slides with the elongated hole 11 is fixedly connected to the end of the rack 15 near the column 7. The blades 12 are arc-shaped, and arc-shaped rubber strips 17 are fixedly connected to both sides along the length direction. The chassis 4 is fixedly connected to the top of the other side of the transmission housing 2. A generator 5 is fixedly connected inside the chassis 4. A through-hole slip ring 18 is provided on the inner bottom wall of the transmission housing 2 near the bottom housing 3. A reducer 29 is fixedly connected to the bottom end of the hollow shaft 6. A drive motor 30 is fixedly connected to the outside of one side of the reducer 29. The output shaft of the drive motor 30 is fixedly connected to the high-speed shaft of the reducer 29. The low-speed shaft of the reducer 29 is coaxially fixed with the synchronous shaft 10. A rotating shaft is fixedly connected to the bottom end of the housing of the reducer 29. The reducer 29 is a worm gear reducer. The rotating shaft is rotatably connected to the through-hole slip ring 18. The bottom end of the hollow shaft 6 extends into the transmission housing 2 and is fixedly connected to a synchronous pulley 19. A synchronous pulley 20 is fixedly connected to the output shaft end of the generator 5. The synchronous pulley 20 is connected to the synchronous belt. Synchronous pulley 19 is connected for transmission. The upper ends of the chassis 4 and the bottom shell 3 are connected through the transmission box 21. Synchronous pulley 22 is fixedly connected to the outer periphery of the top of the hollow shaft 6. A rotating rod 23 is rotatably connected to the side of the transmission box 21 away from the bottom shell 3 through a bearing. Synchronous pulley 24 is fixedly connected to the middle of the rotating rod 23. Synchronous pulley 24 is connected to synchronous pulley 22 through a synchronous belt. The bottom end of the rotating rod 23 extends into the interior of the chassis 4 and is fixedly connected to a fan blade 25. Ventilation openings 26 are provided on both sides of the chassis 4. A water baffle 27 is fixedly connected to the exterior of the chassis 4 on the side of the ventilation opening 26. A dustproof net 28 is fixedly connected in the ventilation opening 26.

[0029] Preferably, the device also includes a wind speed detection unit and a controller. The wind speed detection unit is fixedly installed on the outside of the housing 4 or the transmission shell 2, and is used to collect the ambient wind speed signal in real time and transmit it to the controller. The controller is electrically connected to the wind speed detection unit, the drive motor 30 and the through-hole slip ring 18. The controller has a preset safe wind speed threshold. When the wind speed value collected by the wind speed detection unit exceeds the threshold, the controller sends a forward rotation command to the drive motor 30 through the through-hole slip ring 18. When the wind speed value falls below the threshold, the controller sends a reverse rotation command to the drive motor 30.

[0030] Preferably, at least one drive disk 9 or synchronous shaft 10 is provided with an angle sensor, the signal line of which is electrically connected to the controller through a through-hole slip ring 18; the angle sensor is used to detect the rotation angle of the drive disk 9 relative to the column 7 in real time, thereby indirectly obtaining the opening and closing status information of the blade 12; the controller determines whether the blade 12 has been fully closed or fully opened according to the signal fed back by the angle sensor, and automatically cuts off the power supply of the drive motor 30 after it is in position to avoid overload damage.

[0031] In this embodiment, through the coordinated use of blades 12, drive disk 9, elongated hole 11, drive rod 16, rack 15, gear 14, drive motor 30 and reducer 29, all arc blades 12 are synchronously rotated and merged into a vertical cylindrical structure under strong wind conditions, so that the net torque generated by the wind acting on the cylindrical surface approaches zero, thereby achieving the purpose of complete wind relief protection.

[0032] By using the hollow shaft 6, synchronous pulley 3 22, synchronous pulley 4 24, rotating rod 23 and fan blade 25 in combination, the fan blade 25 is driven by the rotation of the wind turbine itself to perform forced air cooling of the inside of the casing 4. There is no need to configure an additional cooling motor or control system. The cooling is automatically completed while the generator 5 generates electricity, which improves the integration and operational reliability of the device.

[0033] All electrical components mentioned in this solution are existing technologies, and each model is only one of them. Any electrical component that meets the requirements of this solution can be used. Those skilled in the art should connect all electrical components and their compatible power supplies via wires. A suitable controller should be selected based on the actual situation to meet control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical connections are completed according to the sequential operation of each electrical component. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0034] Working principle: When natural wind blows towards the blade 12, due to the arc-shaped structure of the blade 12, it can effectively capture wind energy. The wind energy drives the blade 12 to revolve around the central axis of the column 7, which in turn drives the guide frame 8 and the fixedly connected column 7 to rotate through the rotating shaft 13. The column 7 drives the hollow shaft 6 to rotate inside the bottom shell 3 through bearings. The synchronous pulley 19 at the bottom of the hollow shaft 6 drives the synchronous pulley 20 at the output shaft end of the generator 5 to rotate through the synchronous belt, thereby driving the generator 5 to generate electricity. At the same time, when the wind speed exceeds the safe range, the external control system sends a signal through the through-hole slip ring 18 to the... The drive motor 30, in its rotating state, is powered and drives the high-speed shaft of the reducer 29 to rotate. After being reduced in speed and torque by the reducer 29, the low-speed shaft drives the synchronous shaft 10 to rotate. The synchronous shaft 10 drives the two drive discs 9 to rotate relative to the column 7. The oblique elongated holes 11 evenly distributed along the circumference of the drive discs 9 push the drive rod 16 through the inclined surface of the hole wall, causing the drive rod 16 to move laterally along the guide groove of the guide frame 8. The drive rod 16 drives the rack 15 to move synchronously, and the rack 15 then meshes with the drive gear 14 to rotate. The gear 14 drives the blade 12 to rotate around the shaft 13. The axis of shaft 13 rotates synchronously, causing all blades 12 to gradually return from the open state and merge into a vertical cylindrical structure. At this time, the arc-shaped rubber strips 17 fixedly connected to both sides of the blades 12 form an elastic seal between the contact surfaces of adjacent blades 12, eliminating gaps to maintain the aerodynamic integrity of the cylindrical surface. The net torque generated by the wind acting on the cylindrical surface approaches zero, thereby achieving wind deceleration protection. When the wind speed drops back to the normal operating range, the control system again supplies reverse power to the drive motor 30 through the through-hole slip ring 18, causing the drive motor 30 to rotate in the reverse direction, which is achieved through the reducer 29 and the synchronous shaft 10. The blades 12 are synchronously reversed and reset to the power generation state, restoring the capture of wind energy. In addition, during the power generation process of the generator 5, the hollow shaft 6 drives the synchronous pulley 3 22 to rotate. The synchronous pulley 3 22 drives the synchronous pulley 4 24 and the rotating rod 23 to rotate through the synchronous belt. The rotating rod 23 drives the fan blades 25 to rotate. The fan blades 25 force the hot air inside the casing 4 to be discharged from the ventilation port 26 on one side, while the cold air outside is drawn in from the ventilation port 26 on the other side, forming a forced convection circulation to reduce the internal temperature of the casing 4. The water shield 27 prevents rainwater from entering, and the dustproof net 28 blocks dust.
