Such small wind turbines usually generate power of 10 kilowatts or less. In order to increase the power generation efficiency of such wind turbines, a steering structure will be set inside them.

[0003] A common direction adjustment structure includes a blade adjustment mechanism for a new energy wind turbine generator set with patent number CN218093300U, which includes a blade mounting shell, on which a groove, a sealing cover, a sealing bearing, a mounting plate and a connecting shaft are provided. The groove is located on the surface of the blade mounting shell, and the sealing cover is sealed and connected to one end of the blade mounting shell through a thread. The outer ring of the sealing bearing is fixedly connected to the inside of the blade mounting shell and is located on the inner periphery of the groove. One end of the mounting plate is fixedly connected to the inner wall of the blade mounting shell.

[0004] Although the above-mentioned adjustment mechanism prevents rainwater from entering the interior of the blade mounting shell from the connection between the blade body and causing rust or damage to the internal components, it drives the blades to adjust their direction through bevel gears. When the blades rotate, they will vibrate due to friction with the air. When the blades vibrate, the bevel gears will rub against each other. As the number of frictions increases, cracks and dents are likely to appear on the bevel gears, which will easily cause the friction temperature between the bevel gears to rise too quickly and increase the friction loss between the bevel gears, which will greatly shorten the service life of the bevel gears. Utility Model Content

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-2 , is the first embodiment of the utility model, which provides an adjustment device, including:

[0031] The fan assembly 100 includes a connecting shell 101, a fan blade 102 connected to one side of the connecting shell 101, and a connecting member 103 connected to the inner wall of the connecting shell 101, wherein a bearing is provided in the connecting shell 101, and the bearing is engaged with the root of the fan blade 102, so that the fan blade 102 can rotate on the connecting shell 101;

[0032] Meanwhile, the figure only shows the fan assembly 100. In actual use, the fan assembly 100 needs to be installed on the support base so that the fan assembly 100 is at a high position;

[0033] The connecting shell 101 is a split and detachable arrangement.

[0034] In summary, because the fan blades 102 can rotate in the connecting shell 101, when the wind speed in a certain direction is faster, the fan blades 102 can be rotated to make the wind blow the fan blades 102 to the faster wind speed, so that the fan assembly 100 rotates faster and generates more electricity.

[0035] Example 2

[0036] Reference Figure 1 to Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0037] The mounting assembly 200 is arranged on the inner wall of the connecting shell 101. The mounting assembly 200 includes a mounting shell 201, a connecting hole 202 arranged on one side of the mounting shell 201, and a fixing frame 203 connected to the inner wall of the mounting shell 201. One side of the mounting shell 201 is connected to one side of the connecting member 103, and the other side of the mounting shell 201 is rotatably connected to one side of the connecting shell 101. A connecting pipe is arranged on one side of the mounting shell 201 away from the connecting member 103. The connecting pipe is rotatably connected to the inner wall of one side of the connecting shell 101 through a bearing. At the same time, the connecting pipe extends out of the connecting shell 101 and can be connected to the main body of the wind turbine generator;

[0038] One side of the fan blade 102 is rotatably connected to the inner wall of the connecting hole 202, wherein a bearing is provided at the root of the fan blade 102, and a fixing tube is connected to the outer side of the bearing by bolts. This fixing tube is fixedly connected to the mounting shell 201 by bolts, so that the fan blade 102 can rotate in the connecting hole 202.

[0039] In summary, when assembling the wind turbine generator, the connecting pipe needs to be connected to the output shaft of the generator, and the fan blades 102 need to be fixed to the mounting shell 201 by connecting bolts on the fixing pipe.

[0040] Example 3

[0041] Reference Figure 1 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0042] A locking assembly 300 is provided on one side of the mounting shell 201, and the locking assembly 300 includes a fixing member 301, a sliding member 302 slidably connected to the outer wall of the fixing member 301, and an elastic member 305 sleeved on the outer wall of the fixing member 301, wherein the cross-sectional shape of the fixing member 301 is a "T" shape, and a serrated continuous protrusion is provided at the bottom of the sliding member 302, and the sliding member 302 can slide on the fixing member 301.

[0043] The top of the fixing member 301 is connected to the inner wall of the mounting shell 201 , and the inner wall of the fixing member 301 is rotatably connected to one side of the fan blade 102 , wherein a bearing is arranged inside the fixing member 301 , and the bearing is sleeved on the root of the fan blade 102 , so that the fan blade 102 can rotate inside the fixing member 301 .

[0044] The outer wall of the fixing member 301 is provided with a slide groove 304, and the inner wall of the sliding member 302 is provided with a protrusion 303, the outer wall of the protrusion 303 is slidably connected with the inner wall of the slide groove 304, and the top of the elastic member 305 is in contact with the top of the sliding member 302, wherein the upper and lower sides of the slide groove 304 are provided with seals, which can ensure that the protrusion 303 will not slide out of the slide groove 304;

[0045] The elastic member 305 is a shock absorbing spring.

[0046] A connecting block 306 is installed on one side of the sliding member 302, and a top rod 307 is connected to the outer wall of the connecting block 306. The bottom of the top rod 307 is rotatably connected to a roller 308. When the top rod 307 and the roller 308 move upward, the sliding member 302 will move upward.

[0047] The outer wall of the fan blade 102 is connected to a pushing assembly 400, which includes a positioning member 401 connected to one side of the fan blade 102, a moving ring 402 connected to the outer wall of the fixing frame 203, a motor 403 connected to one side of the moving ring 402, and an electric telescopic rod 406 connected to the outer wall of the fixing frame 203, wherein the positioning member 401 is fixedly connected to the fan blade 102 by bolts, and continuous serrated protrusions are provided on the upper and lower sides thereof;

[0048] The electric telescopic rod 406 is a universal standard component or a component known to those skilled in the art, and its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0049] The top of the positioning member 401 is meshed with the bottom of the fixing member 301, a groove 404 is provided on one side of the moving ring 402, the bottom of the roller 308 is connected to the top of the groove 404, wherein the cross-sectional shape of the groove 404 is a trapezoid, when the moving ring 402, the groove 404 will push the roller 308 to rise.

[0050] The output end of the motor 403 is provided with a transmission wheel 405, and the output end of the electric telescopic rod 406 is connected to the outer wall of the moving ring 402. When the electric telescopic rod 406 pulls the moving ring 402 to move toward the fan blade 102, the motor 403 and the transmission wheel 405 will be driven to move toward the fixing member 301. At this time, the motor 403 can be started to drive the transmission wheel 405 to rotate, thereby driving the fixing member 301 to rotate;

[0051] The transmission wheel 405 here is made of polyurethane rubber.

[0052] In summary, when the angle of the fan blade 102 needs to be adjusted, the electric telescopic rod 406 is used to pull the moving ring 402 to move in the direction of the fan blade 102, so that the groove 404 will push the roller 308 to rise, so that the top rod 307 and the roller 308 move upward, and the sliding member 302 will squeeze the elastic member 305 upward. At this time, the sliding member 302 is no longer engaged with the positioning member 401. At this time, continuing to pull the moving ring 402 can make the transmission wheel 405 contact the positioning member 401, and then start the motor 403 to drive the transmission wheel 405 and the fixing member 301 to rotate, so that the angle of the fan blade 102 changes. After the adjustment is completed, the electric telescopic rod 406 pushes the moving ring 402 back to its original position, so that the elastic member 305 pushes the sliding member 302 down and locks the positioning member 401, so that the fan blade 102 is fixed again. In this way, when the fan blade 102 vibrates, the force will be transmitted to the elastic member 305. At this time, the elastic member 305 can absorb most of the force to reduce the impact of the vibration force on other components. At the same time, the transmission wheel 405 and the motor 403 as the power source do not contact the fan blade 102. This can greatly reduce the impact on the transmission wheel 405 and the motor 403, thereby extending the service life of the transmission wheel 405, the motor 403 and other parts.

[0054] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
