[0002] Wind power generation refers to a power generation method that converts the kinetic energy of wind into electrical energy. The equipment used is called power generation equipment. Generally, wind power generation equipment with a power generation capacity of 10 kilowatts or less is called small wind power generation equipment. Small wind power generation equipment mainly consists of components such as a wind turbine, a generator, a rotating body, a speed regulating mechanism, a direction regulating mechanism, a braking mechanism, and a tower, and is often installed on the top of street lamps.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects:

[0004] Existing small wind power generation equipment is mostly fixed to the base by a bolt structure. After installation and fixation, it is inconvenient to adjust the direction according to the actual use situation, resulting in poor adaptability in use and reducing the wind energy utilization efficiency. Therefore, it is necessary to provide a small wind power generation equipment with adjustable direction to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a small wind power generation equipment with adjustable direction to solve the problem that existing small wind power generation equipment is mostly fixed to the base by a bolt structure.

[0006] The technical solution of the utility model is: a small wind power generation equipment with adjustable direction, including a fan generator main body and a base. A wind speed and direction sensor is fixedly installed at the bottom of the fan generator main body. A fixed box body is fixedly installed on the upper surface of the base, and a column passing through the fixed box body is rotatably connected to the upper surface of the base. An annular groove is opened on the outer side of the column, and a limit gear is fixedly installed inside the annular groove. An electric telescopic rod is fixedly installed inside the fixed box body, and a block engaging with the limit gear is fixedly connected to the output end of the electric telescopic rod. A driving motor is embedded at the bottom of the base, and the output shaft of the driving motor is fixedly connected to the column.

[0007] Preferably, the bottom of the block contacts the base, and four fixing holes are evenly opened on the upper surface of the base.

[0008] Preferably, the fan generator main body includes a connecting shaft arranged at one end, and three fan blades are evenly fixedly installed on the outer side of the connecting shaft.

[0009] Preferably, a connection groove is formed at the upper end of the column, and a connection column inserted into the connection groove is fixedly installed at the bottom of the main body of the wind turbine generator.

[0010] Preferably, a notch communicating with the connection groove is formed on the outer side of the column, a limiting hole is formed on one side of the connection column, and a limiting block is jointly inserted into the limiting hole and the notch.

Specific implementation mode

[0023] The following is a detailed description of the present utility model. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0024] As Figures 1-5 shown, a small - sized wind power generation device with adjustable direction provided by the present utility model includes a fan - generator main body 3 and a base 1. A wind speed and direction sensor 18 is fixedly installed at the bottom of the fan - generator main body 3. A fixed box body 2 is fixedly installed on the upper surface of the base 1, and a column 5 passing through the fixed box body 2 is rotatably connected to the upper surface of the base 1. An annular groove 17 is formed on the outer side of the column 5, and a limit gear 12 is fixedly installed on the inner side of the annular groove 17. An electric telescopic rod 7 is fixedly installed inside the fixed box body 2, and a block 13 engaged with the limit gear 12 is fixedly connected to the output end of the electric telescopic rod 7. A driving motor 19 is embedded at the bottom of the base 1, and a fixed connection is established between the output shaft of the driving motor 19 and the column 5.

[0025] Furthermore, the bottom of the block 13 is in contact with the base 1, and four fixed holes 6 are evenly formed on the upper surface of the base 1, which is convenient for fixing the base 1 at the working position by using bolts through the fixed holes 6.

[0026] During implementation, a limit gear 12 is arranged on the outer side of the column 5. After rotating the column 5 and the fan - generator main body 3 by a certain angle, the electric telescopic rod 7 is adjusted so that the block 13 connected to its output end is engaged with the limit gear 12, thereby conveniently adjusting and fixing the angle of the fan - generator main body 3. This solves the problem that most existing small - sized wind power generation devices are fixed to the base by bolt structures, and it is inconvenient to adjust the direction according to the actual use situation after installation and fixation, resulting in poor adaptability in use and reduced wind energy utilization efficiency.

[0027] The main body 3 of the wind turbine generator includes a connecting shaft 14 arranged at one end. Three fan blades 15 are evenly and fixedly installed on the outer side of the connecting shaft 14. A connecting groove 8 is opened at the upper end of the column 5. A connecting column 11 inserted into the connecting groove 8 is fixedly installed at the bottom of the main body 3 of the wind turbine generator. A notch 16 communicating with the connecting groove 8 is opened on the outer side of the column 5. A limiting hole 9 is opened on one side of the connecting column 11. A limiting block 10 is jointly inserted into the limiting hole 9 and the notch 16. A threaded sleeve 4 is screwed on the outer side of the column 5. The threaded sleeve 4 is located on the outer side of the limiting block 10. The connecting column 11 has a rectangular structure, and the connecting column 11 and the main body 3 of the wind turbine generator are integrally formed structures.

[0028] In implementation, the connecting column 11 and the connecting groove 8 are used for inserting between the main body 3 of the wind turbine generator and the column 5. At the same time, the limiting block 10 is inserted into the limiting hole 9 opened on the connecting column 11, and the threaded sleeve 4 is screwed on the outer side of the limiting block 10, so that the main body 3 of the wind turbine generator and the column 5 can be conveniently connected and fixed, improving the assembly efficiency.

[0029] Working principle: During assembly, first insert the connecting column 11 connected to the main body 3 of the wind turbine generator into the connecting groove 8, then insert the limiting block 10 into the notch 16 and the limiting hole 9, and finally rotate the threaded sleeve 4 upward so that it wraps around the outer side of the limiting block 10. Then, use bolts to fix the base 1 to the working area through the fixing holes 6. When the wind speed and direction sensor 18 detects a change in the wind speed and direction, it sends a signal to the corresponding controller to command the driving motor 19 and the electric telescopic rod 7 to start. At this time, the electric telescopic rod 7 drives the clamping block 13 connected to its output end to disengage from the tooth gap of the limiting gear 12. At the same time, the output shaft of the driving motor 19 drives the column 5 and the main body 3 of the wind turbine generator to rotate a certain angle. After the adjustment angle is in place, the electric telescopic rod 7 starts again to make the clamping block 13 clamped in the tooth gap of the limiting gear 12, so that the main body 3 of the wind turbine generator after the adjustment angle is fixed.

[0030] The above description enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
