[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a wind power tower, in which wind acts on the blades to rotate them, thereby driving the wind turbine generator set to generate electricity. The blade rod is kept in a horizontal position by a fixing plate to ensure that the blade is in a balanced state. The synergistic effect of the fixing block, the fixing rod and the fixing ring enhances its stability without hindering the rotation of the blade rod. The design of the mounting block enables the main structure to be conveniently installed inside the supporting structure. When the wind speed faced by the blade is low, the adjustment device can adjust the direction of the blade to increase the wind force received by the blade and ensure the efficiency of wind power generation. The indication of the adjustment device is synchronized with the direction of the blade, which is convenient for accurately determining the direction of the blade during the adjustment process. 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 direction of the blade is adjusted to a suitable position, the dial plate is released, and the reset spring will push the reset plate to make the clamping rod mesh with the gear, thereby locking the direction of the blade, facilitating the stable rotation of the blade, and improving the flexibility of the device.

[0011] 2. The present invention uses a base plate to firmly fix the device to the ground. Thanks to the narrow top and wide bottom design of the bracket, the overall stability of the device is enhanced. The fixing nut ensures that the main mechanism is firmly installed inside the bracket. When the wind direction needs to be adjusted, the wind direction is determined by the indication of the wind vane, and then the indicator is adjusted to be consistent with the wind vane to ensure that the fan blades withstand the maximum wind force, thereby increasing the power output of the wind turbine box. However, if the wind force is too strong, the stability of the device may be impaired. At this time, the piston rod compression spring 1 and the touch rod can absorb most of the pressure, further enhancing the stability of the device. If the wind force exceeds the bearing limit of spring 1 and the touch rod, the touch rod will squeeze the pressure sensor, and the pressure sensor will then send a signal to the controller, and the controller will then drive the buzzer to sound an alarm to warn the surrounding personnel to evacuate quickly to avoid personal injury caused by the collapse of the device, thereby improving the safety of the device.

[0017] Example 1. Figure 1-6As shown, the present invention provides a wind power generation tower, including a support mechanism 1, a main body mechanism 2 is arranged inside the support mechanism 1, the main body mechanism 2 includes a mounting block 21, the mounting block 21 is movably connected to the inside of the top surface of the support mechanism 1, a threaded hole is arranged on the side of the mounting block 21, a rotating rod 25 is rotatably connected inside the mounting block 21, a limiting ring 23 is fixedly connected to the top of the outer surface of the rotating rod 25, the limiting 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 power generation box 24, a fan blade device 28 is rotatably connected inside the wind power generation box 24, a fixing block 29 is fixedly connected to the top surface of the wind power generation box 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 adjusting device 26 is provided on the bottom surface of the rotating rod 25, an indicator 27 is fixedly connected to the bottom end of the outer surface of the rotating rod 25, and the blade device 28 includes a blade rod 281, which is rotatably connected to the inside of the wind power box 24, one end of the blade rod 281 passes through the side of the wind power box 24 and is fixedly connected to a fixing plate 282, and a fixing groove 283 is provided on the other end of the outer surface of the blade rod 281, the interior of the fixing ring 211 is movably connected to the outer surface of the fixing groove 283, and a blade 284 is fixedly connected to the side of the blade rod 281.

[0018] In this embodiment, the fan blades 284 are rotated by the wind, and when the fan blades 284 rotate, they will drive the wind turbine box 24 to generate electricity. The fixing plate 282 keeps the fan blade rod 281 horizontal, driving the fan blades 284 to be in a horizontal state. The cooperation of the fixing block 29, the fixing rod 210, and the fixing ring 211 will make the fan blade rod 281 more stable without affecting the rotation of the fan blade rod 281. The mounting block 21 can make the main body 2 more convenient to install inside the support mechanism 1. When the wind speed in the direction facing the fan blades 284 is small, the direction of the fan blades 284 can be adjusted by the adjusting device 26 to make the wind force on the fan blades 284 greater. The indicator 27 is consistent with the direction of the fan blades 284, so that the direction of the fan blades 284 can be determined during adjustment.

[0019] Example 2. Figure 1-6As shown, on the basis of Example 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, the bottom surface of the gear 262 is fixedly connected to the motor 263, the gear 262 is fixedly connected to the output shaft of the motor 263, the side of the motor 263 is fixedly connected to the connecting block 264, the top surface of the connecting block 264 is fixedly connected to the mounting plate 261, the side of the gear 262 is clamped with a clamping rod 265, the bottom surface of the clamping rod 265 is fixedly connected to a reset plate 266, the outer surface of the reset plate 266 is movably connected to a fixed slider 269, the side of the reset plate 266 is fixedly connected to a reset spring 267, the top surface of the clamping rod 265 is fixedly connected to a dial plate 268, and the outer surface of the clamping rod 265 is slidably connected to the inside of the side of the fixed slider 269.

[0020] 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 with it. Since the top and bottom ends of the rotating rod 25 are fixed, its rotation process is very stable. When the direction of the fan blade 284 is appropriate, the shift plate 268 is released to allow the reset spring 267 to push the reset plate 266, driving the locking rod 265 to lock the gear 262. At this time, the direction of the fan blade 284 is fixed, which facilitates the rotation of the fan blade 284.

[0021] Example 3. Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the support mechanism 1 includes a base plate 11, the top surface of the base plate 11 is connected to a bracket 12, a mounting plate 261 is fixedly connected to the inner top end of the base plate 11, a fixed slider 269 is fixedly connected to the inner bottom surface of the base plate 11, a mounting block 21 is movably connected to the inside of the top surface of the bracket 12, a fixing nut 13 is movably connected to the inside of the side top end of the mounting block 21, one end of the fixing nut 13 passes through the side surface of the bracket 12 and is threadedly connected to the mounting block 21, a support device 14 is fixedly connected to the inside of the bracket 12, an extension plate 15 is fixedly connected to the side of the base plate 11, a bearing 16 is fixedly connected to the top surface of the extension plate 15, a heightening rod 17 is fixedly connected to the top surface of the bearing 16, and a weather vane 18 is fixedly connected to the top surface of the heightening rod 17.

[0022] In this embodiment, the entire device is fixed to the ground through the base plate 11. Due to the structure of the bracket 12 that is wide at the top and narrow at the bottom, the entire device can be more stable. The fixing nut 13 can fix the main body mechanism 2 when it is installed inside the bracket 12. When the wind direction needs to be adjusted, the direction of the wind vane 18 can be observed to determine the direction of the wind. When the direction of the adjustment indicator 27 is consistent with the direction of the wind vane 18, the wind force borne by the fan blades 284 is the largest, and the wind turbine box 24 can be driven to generate more electricity.

[0023] Example 4. Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the supporting device 14 includes a stabilizing plate 141, the stabilizing plate 141 is fixedly connected to the inside of the bracket 12, the side of the stabilizing plate 141 is movably connected with a piston rod 142, the outer surface of the piston rod 142 is slidably connected with a sleeve 143, the side of the piston rod 142 is fixedly connected with a spring 2 146, the other side of the piston rod 142 is fixedly connected with a spring 144, the other end of the spring 144 is fixedly connected to the inner top end of the sleeve 143, the side center of the piston rod 142 is fixedly connected with a touch rod 145, the side of the touch rod 145 is fixedly connected with a pressure sensor 147, and the pressure sensor 147 is electrically connected to the controller 212.

[0024] In this embodiment, when the wind force is too strong, it may cause instability of the device. At this time, the piston rod 142 compresses the spring 144 and the touch rod 145 to relieve most of the pressure and make the device more stable. When the spring 144 and the touch rod 145 reach an unbearable wind force, the touch rod 145 will squeeze the pressure sensor 147, and the pressure sensor 147 will send a signal to the controller 212. The controller 212 drives the buzzer 22 to sound, which has the effect of warning, allowing people around to evacuate quickly, preventing the device from collapsing and causing casualties.

[0025] The working principle of this wind power tower: Figure 1-6 As shown, by moving the entire device to a suitable position and fixing another stabilizing plate 141 on 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 the mounting block 21 is fixed by the fixing nut 13 to complete 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, the speed of the fan blade 284 decreases, and the power generation efficiency is low, the dial plate 268 is moved to make the clamping rod 265 release the clamping of the gear 262. At this time, the motor 263 will drive the rotating rod 25 to rotate, and the direction of the fan blade 284 will also change accordingly. When the direction of the indicator 27 is consistent with the direction of the wind vane 18, the fan blade 284 will be in the same direction as the wind vane 18. When the wind force that fan blade 284 can withstand is the largest, the dial plate 268 is released, and the reset spring 267 pushes the reset plate 266, which drives the clamping rod 265 to clamp the gear 262 and fix the position of the fan blade 284. When the wind force is too strong, the device may become unstable. At this time, the piston rod 142 compresses the spring 144 and the touch rod 145 to relieve most of the pressure and make the device more stable. When the spring 144 and the touch rod 145 reach a wind force that they cannot withstand, the touch rod 145 will squeeze the pressure sensor 147, and the pressure sensor 147 will send a signal to the controller 212. The controller 212 drives the buzzer 22 to sound a buzzer, which has a warning effect, allowing people around to evacuate quickly, thereby preventing the device from collapsing and causing casualties.

[0026] Obviously, the above is only a part of the embodiments of the present invention, not all of the embodiments. The above embodiments are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any combination, modification, equivalent replacement, improvement and all other embodiments that can be made by those of ordinary skill in the art within the spirit and principle of the present invention should be within the protection scope of the present invention.
