Description

Technical Field

[0001] This invention relates to the field of wind power generation tower technology, and in particular to a wind power generation tower. Background Technology

[0002] Wind power generation systems involve technologies that generate electricity by converting wind power into rotational force; they are systems that convert wind energy into mechanical energy and drive a generator to produce electricity. Patent publication number CN105452649A discloses a wind power tower. According to one embodiment of the invention, the wind power tower can accelerate wind speeds even in low-speed winds to generate electricity, while also improving the utilization efficiency of wind for the rotating blades, thereby increasing overall power generation efficiency. Furthermore, the wind power tower according to one embodiment of the invention can enhance wind power through the Venturi effect, and by utilizing vortices generated on the back of the cylindrical wind power tower, it increases the pressure drop of the wind passing through the tower, thereby further improving the rotation of the blades installed inside the tower. To address the instability of wind direction and force and effectively improve wind power generation efficiency, current technologies adopt multi-inlet and multi-outlet airflow designs. However, due to the variability of wind direction, wind power generation efficiency may still be affected when the wind direction changes, leading to a decrease in efficiency. Summary of the Invention

[0003] This invention provides a wind power generation tower, aiming to solve the problem of low wind power generation efficiency when the wind direction changes due to the variable wind direction.

[0004] The present invention provides the following technical solution to achieve the above objectives:

[0005] A wind power tower includes a support mechanism, inside which is a main structure. The main structure includes a mounting block, which is movably connected to the top surface inside the support mechanism. A rotating rod is movably mounted inside the mounting block, with its top end passing through the mounting block and connected to a wind turbine housing. A limit ring is fixedly connected to the top of the outer surface of the rotating rod, which is in close contact with the bottom surface of the mounting block. An adjustment device is provided at the bottom of the rotating rod, and an indicator is provided at the bottom of the rotating rod. The wind turbine housing is rotatably connected to a fan blade assembly.

[0006] Furthermore, the fan blade device includes a fan blade rod, which is rotatably mounted inside the wind power generator box. One end of the fan blade rod is connected to a fixing plate, and the other end of the fan blade rod is provided with a fan blade. A fixing groove is provided on the side of the fan blade rod adjacent to the fan blade, and a fixing ring is movably mounted in the fixing groove.

[0007] Furthermore, a fixing block is fixedly connected to the top surface of the wind turbine box, and a fixing rod is provided on the side of the fixing block facing the fan blade. The fixing rod is connected to a fixing ring, and a controller is provided on the fixing block. A buzzer is provided on the controller.

[0008] Furthermore, the adjustment device includes a motor, which is connected to the mounting plate via a connecting block. A gear is mounted on the output shaft of the motor, and the gear is fixedly connected to the bottom end of the rotating rod. A locking rod is mounted on the gear, and a reset plate is fixedly connected to the bottom surface of the locking rod. A fixed slider is movably connected to the outer surface of the reset plate, and a reset spring is fixedly connected to the side of the reset plate. A lever is fixedly connected to the top surface of the locking rod, and the outer surface of the locking rod is slidably connected to the inside of the side of the fixed slider.

[0009] Furthermore, the support mechanism includes a base plate, a bracket connected to the top surface of the base plate, a mounting block movably disposed inside the top surface of the bracket, and a fixing nut movably connected to the top side of the mounting block. One end of the fixing nut passes through the side of the bracket and is threadedly connected to the mounting block. An extension plate is fixedly connected to the side of the base plate, a bearing is fixedly connected to the top surface of the extension plate, a heightening rod is fixedly connected to the top surface of the bearing, and a wind vane is fixedly connected to the top surface of the heightening rod. The mounting plate is fixedly connected to the inner top of the base plate, and a fixing slider is provided on the inner bottom surface of the base plate.

[0010] Furthermore, the bracket is equipped with a support device, which includes a stabilizing plate fixedly connected inside the bracket. A piston rod is movably connected to the side of the stabilizing plate, and a sleeve is slidably connected to the outer surface of the piston rod. A second spring is fixedly connected to the side of the piston rod, and a first spring is fixedly connected to the other side of the piston rod. The other end of the first spring is fixedly connected to the top of the inner sleeve. A contact rod is fixedly connected to the center of the side of the piston rod, and a pressure sensor is fixedly connected to the side of the contact rod. The pressure sensor is electrically connected to the controller.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This invention provides a wind power generation tower. Wind force acts on the blades, causing them to rotate, thereby driving a wind turbine generator to generate electricity. The blade stalk is kept horizontal by a fixing plate, ensuring the blade is in a balanced state. The synergistic effect of the fixing block, fixing rod, and fixing ring enhances stability without hindering the rotation of the blade stalk. The design of the mounting block allows the main structure to be easily installed inside the support structure. When the wind speed facing the blade is low, the adjustment device can adjust the blade direction to increase the wind force on the blade and ensure wind power generation efficiency. The indication of the adjustment device is synchronized with the blade direction, facilitating accurate determination of the blade direction during adjustment. The rotating rod is fixedly connected to the top surface of the gear, so that when the motor drives the gear to rotate, the rotating rod can also rotate synchronously. Since both ends of the rotating rod are fixed, its rotation process is extremely stable. When the blade direction is adjusted to the appropriate position, the lever is released, and the return spring pushes the return plate, causing the locking rod to mesh with the gear, thereby locking the blade direction, facilitating stable blade rotation, and improving the flexibility of the device.

[0013] 2. This invention uses a base plate to firmly fix the device to the ground. Thanks to the top-narrow, bottom-wide design of the support frame, the overall stability of the device is enhanced. The fixing nuts ensure the stable installation of the main structure inside the support frame. When wind direction adjustment is needed, the wind direction is determined by the wind vane, and the parameters are adjusted to match the wind vane to ensure the fan blades can withstand maximum wind force, thereby increasing the power output of the wind turbine. However, if the wind force is too strong, it may compromise the stability of the device. In this case, the piston rod compresses the spring and the contact rod, absorbing most of the pressure and further enhancing the stability of the device. If the wind force exceeds the bearing limit of the spring and the contact rod, the contact rod will press the pressure sensor, which then sends a signal to the controller. The controller then drives the buzzer to sound an alarm to warn surrounding personnel to evacuate quickly, preventing the device from collapsing and causing injury, thus improving the safety of the device.

[0024] Example 1. As... Figure 1-6As shown, the present invention provides a wind power tower, including a support mechanism 1, a main body mechanism 2 is arranged inside the support mechanism 1, and the main body mechanism 2 includes a mounting block 21, which is movably connected to the top surface of the support mechanism 1. A threaded hole is provided on the side of the mounting block 21. A rotating rod 25 is rotatably connected inside the mounting block 21. A limit ring 23 is fixedly connected to the top of the outer surface of the rotating rod 25, and the limit ring 23 is tightly attached to the bottom surface of the mounting block 21. One end of the rotating rod 25 passes through the top surface of the mounting block 21 and is fixedly connected to a wind turbine housing 24. A fan blade device 28 is rotatably connected inside the wind turbine housing 24. A fixing block 29 is fixedly connected to the top surface of the wind turbine housing 24, and a fixing rod 21 is fixedly connected to the side of the fixing block 29. 0. A fixing ring 211 is fixedly connected to the side of the fixing rod 210. A controller 212 is fixedly connected to the side of the fixing block 29. A buzzer 22 is fixedly connected to the top surface of the controller 212. An adjustment device 26 is provided on the bottom surface of the rotating rod 25. An index 27 is fixedly connected to the bottom end of the outer surface of the rotating rod 25. The fan blade device 28 includes a fan blade rod 281. The fan blade rod 281 is rotatably connected to the inside of the wind turbine box 24. One end of the fan blade rod 281 passes through the side of the wind turbine box 24 and is fixedly connected to a fixing plate 282. The other end of the outer surface of the fan blade rod 281 is provided with a fixing groove 283. The inside of the fixing ring 211 is movably connected to the outer surface of the fixing groove 283. A fan blade 284 is fixedly connected to the side of the fan blade rod 281.

[0025] In this embodiment, the fan blade 284 is rotated by the wind. When the fan blade 284 rotates, it drives the wind power generation box 24 to generate electricity. The fixing plate 282 keeps the fan blade rod 281 horizontal, thus keeping the fan blade 284 in a horizontal state. The cooperation of the fixing block 29, fixing rod 210, and fixing ring 211 makes the fan blade rod 281 more stable without affecting its rotation. The mounting block 21 makes it easier to install the main body mechanism 2 inside the support mechanism 1. When the wind speed in the direction in which the fan blade 284 is facing is low, the direction of the fan blade 284 can be adjusted by the adjusting device 26 to generate a greater wind force on the fan blade 284. The index 27 is consistent with the direction of the fan blade 284, making it convenient to determine the direction of the fan blade 284 during adjustment.

[0026] Example 2. (As shown) Figure 1-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the adjusting device 26 includes a gear 262, which is fixedly connected to the bottom surface of the rotating rod 25. A motor 263 is fixedly connected to the bottom surface of the gear 262. The gear 262 is fixedly connected to the output shaft of the motor 263. A connecting block 264 is fixedly connected to the side of the motor 263. A mounting plate 261 is fixedly connected to the top surface of the connecting block 264. A locking rod 265 is engaged with the side of the gear 262. A reset plate 266 is fixedly connected to the bottom surface of the locking rod 265. A fixed slider 269 is movably connected to the outer surface of the reset plate 266. A reset spring 267 is fixedly connected to the side of the reset plate 266. A lever 268 is fixedly connected to the top surface of the locking rod 265. The outer surface of the locking rod 265 is slidably connected to the inside of the side of the fixed slider 269.

[0027] In this embodiment, the rotating rod 25 is fixedly connected to the top surface of the gear 262, so that when the motor 263 drives the gear 262 to rotate, the rotating rod 25 on the top surface can rotate together with it. Since the top and bottom ends of the rotating rod 25 are fixed, its rotation process is very stable. When the fan blade 284 is in the right orientation, the lever 268 is released, causing the return spring 267 to push the return plate 266, which drives the locking rod 265 to lock the gear 262. At this time, the orientation of the fan blade 284 is fixed, which facilitates the rotation of the fan blade 284.

[0028] Example 3. (As shown) Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the support mechanism 1 includes a base plate 11, a bracket 12 connected to the top surface of the base plate 11, a mounting plate 261 fixedly connected to the inner top of the base plate 11, a fixed slider 269 fixedly connected to the inner bottom surface of the base plate 11, a mounting block 21 movably connected to the inner top surface of the bracket 12, a fixing nut 13 movably connected to the inner top side of the mounting block 21, one end of the fixing nut 13 penetrating the side of the bracket 12 and threadedly connected to the mounting block 21, a support device 14 fixedly connected inside the bracket 12, an extension plate 15 fixedly connected to the side of the base plate 11, a bearing 16 fixedly connected to the top surface of the extension plate 15, a heightening rod 17 fixedly connected to the top surface of the bearing 16, and a wind vane 18 fixedly connected to the top surface of the heightening rod 17.

[0029] In this embodiment, the entire device is fixed to the ground by the base plate 11. Due to the structure of the bracket 12 being wider at the top and narrower at the bottom, the entire device can be more stable. The fixing nut 13 can fix the main body 2 when it is installed inside the bracket 12. When it is necessary to adjust the wind direction, the direction of the wind can be determined by observing the direction of the wind vane 18. When the direction of the adjustment index 27 is consistent with the direction of the wind vane 18, the wind force borne by the fan blade 284 is the greatest, which can generate more electricity to drive the wind power generation box 24.

[0030] Example 4. (As shown) Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the support device 14 includes a stabilizing plate 141, which is fixedly connected to the inside of the bracket 12. A piston rod 142 is movably connected to the side of the stabilizing plate 141. A sleeve 143 is slidably connected to the outer surface of the piston rod 142. A second spring 146 is fixedly connected to the side of the piston rod 142. A first spring 144 is fixedly connected to the other side of the piston rod 142. The other end of the first spring 144 is fixedly connected to the top end of the sleeve 143. A contact rod 145 is fixedly connected to the center of the side of the piston rod 142. A pressure sensor 147 is fixedly connected to the side of the contact rod 145. The pressure sensor 147 is electrically connected to the controller 212.

[0031] In this embodiment, when the wind force is too strong, it may cause instability of the device. At this time, the piston rod 142 can compress the spring 144 and the contact rod 145 to relieve most of the pressure and make the device more stable. When the spring 144 and the contact rod 145 reach the wind force that cannot be withstood, the contact rod 145 will squeeze the pressure sensor 147. The pressure sensor 147 will send a signal to the controller 212. The controller 212 will drive the buzzer 22 to sound, which will serve as a warning and allow people in the vicinity to evacuate quickly to prevent the device from collapsing and causing casualties.

[0032] The working principle of this wind power tower is as follows: Figure 1-6 As shown, by moving the entire device to a suitable position and fixing another stabilizing plate 141 to the ground, the stability of the entire device is improved. At this time, the mounting block 21 is inserted from the top surface of the bracket 12 and fixed by the fixing nut 13, completing the installation of the entire device. The rotation of the fan blade 284 drives the fan blade rod 281 to rotate inside the wind turbine box 24 to complete the power generation work. When the wind direction changes and the fan blade 284 speed decreases, the power generation efficiency is low. When the toggle plate 268 is moved, the locking lever 265 is disengaged from the gear 262. At this time, the motor 263 will drive the rotating rod 25 to rotate, and the orientation of the fan blade 284 will also change accordingly. When the orientation of the indicator 27 is consistent with the orientation of the wind vane 18, the fan blade... 284 can withstand the maximum wind force. When the lever 268 is released, the reset plate 266 is pushed by the reset spring 267, which drives the locking rod 265 to engage with the gear 262, fixing the position of the fan blade 284. When the wind force is too strong, it may cause the device to become unstable. At this time, the piston rod 142 can compress the spring 144 and the contact rod 145 to relieve most of the pressure and make the device more stable. When the spring 144 and the contact rod 145 reach the wind force that cannot be withstood, the contact rod 145 will squeeze the pressure sensor 147. The pressure sensor 147 will send a signal to the controller 212. The controller 212 will drive the buzzer 22 to sound, which will serve as a warning and allow people in the vicinity to evacuate quickly to prevent the device from collapsing and causing casualties.

[0033] Obviously, the above description is only a part of the embodiments of the present invention, and not all of the embodiments. The above embodiments are not intended to limit the present invention, and various modifications and variations can be made to the present invention by those skilled in the art. Any combination, modification, equivalent substitution, improvement, and all other embodiments that can be made by those skilled in the art within the spirit and principles of the present invention should be within the protection scope of the present invention.
