Micro wind power generation mainly uses a vertical axis wind turbine, which can convert wind energy into electrical energy in a gentle breeze environment.

[0003] For example, a micro wind power generation device convenient for replacing fan blades with the authorization announcement number of "CN221628316U" preliminarily ensures that the main shaft and the middle shaft can rotate synchronously by the cross limit block extending into the cross limit groove, and then positions the middle shaft by relying on the positioning component to prevent the middle shaft from disengaging from the insertion groove on the main shaft, so as to connect the main shaft and the middle shaft, that is, install the fan blade. However, when replacing the fan blade of this device for the micro wind power generation equipment, it is necessary to disassemble the entire rotating part, that is, remove the three groups of fan blades at the same time. When one fan blade is damaged, it is also necessary to replace the entire rotating part, resulting in a high cost for maintenance and replacement of this device, and at the same time, the disassembly method of this device is relatively single.

[0013] For a breeze power generation device with easily replaceable fan blades proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the locking device and the fixing device, when only one group of fan blades is damaged, the operator rotates the fourth bolt so that the fourth bolt is no longer threadedly connected to the second base. The operator pulls the circular plate, so that the circular plate can drive the two bolts on both sides to move outward from the second base, so that the two bolts on both sides are no longer inserted into the fan blade, enabling the operator to pull out the damaged fan blade and replace a single fan blade. When two or more fan blades are damaged, the operator rotates the two second bolts on both sides so that the two second bolts on both sides are no longer inserted into the groove rod. The operator pulls out the groove rod so that the groove rod is no longer clamped with the convex rod, and then the three groups of fan blades can be replaced simultaneously.

[0024] The inner wall of the second ring 905 fits against the outer wall of the groove rod 10. One end of each of the two second bolts 906 on both sides is inserted into the groove formed on the surface of the groove rod 10. The inner wall of the cylinder 5 fits against the outer wall of the groove rod 10. The groove formed at one end of the groove rod 10 is inserted into the protruding part of the convex rod 11. A cross-shaped groove is formed at one end of the groove rod 10, and the size of the groove is engaged with the cross-shaped protrusion at one end of the convex rod 11. A rotating block 7 is fixedly connected to the left end of the groove rod 10. Multiple locking devices 8 are provided on the outer wall of the rotating block 7. The base two 804 is inserted into the fan blade 6 through the groove formed on its surface. The fan blade 6 is installed by means of insertion, enabling the separate disassembly of the fan blade 6. The fan blade 6 fits against the pin 803 through the through hole formed on its surface.

[0025] The fixing device 9 includes a connecting block 901 and a support rod 902. One end of each of multiple support rods 902 is fixedly connected to the cylinder 5. Multiple support rods 902 can fix the first ring 903. The other end of the support rod 902 is fixedly connected to the connecting block 901. One end of each of multiple connecting blocks 901 is fixedly connected to the first ring 903. The inner wall of the first ring 903 is rotatably connected to the second ring 905 through a bearing. The first ring 903 can support the second ring 905 to continue rotating. At the same time, the second ring 905 can support the groove rod 10. The third ring 904 can rotate synchronously with the second ring 905. At the same time, the third ring 904 can be fixed to the groove rod 10 through the two second bolts 906 on both sides, enabling the groove rod 10 to drive the second ring 905 to rotate synchronously. The third ring 904 is fixedly connected to the left end of the second ring 905. The third ring 904 is slidably connected to the two second bolts 906 respectively through the through holes formed on its surface.

[0027] Working principle:

[0028] When using the micro-wind power generation device:

[0029] When the wind passes through the three groups of fan blades 6, it will push the three groups of fans 6 to drive the rotating block 7 to rotate, enabling the rotating block 7 to drive the groove rod 10 to rotate synchronously. The groove rod 10 can drive the second ring 905 to rotate synchronously through the third ring 904. At the same time, the groove rod 10 can drive the convex rod 11 to rotate, and the convex rod 11 can drive the equipment inside the generator main body 1 to rotate. The rotating magnetic field generated by the rotation of the internal structure of the generator main body 1 will cut the magnetic induction lines passing through the wire winding, thereby generating an induced electromotive force, and then generating an electric current to convert mechanical energy into electrical energy.

[0030] Disassembly process:

[0031] When only one group of fan blades 6 is damaged, the operator rotates the fourth bolt 801 so that the fourth bolt 801 is no longer threadedly connected to the base one 4. The operator pulls the round plate 802, enabling the round plate 802 to drive the two side pins 803 to move outward from the base two 804, so that the two side pins 803 are no longer inserted into the fan blades 6, allowing the operator to pull out the damaged fan blades 6 and replace them individually. When two or more of the fan blades 6 are damaged, the operator rotates the two side second bolts 906 so that the two side second bolts 906 are no longer inserted into the groove rod 10. The operator pulls out the groove rod 10 so that the groove rod 10 is no longer clamped with the convex rod 11, and then the three groups of fan blades 6 can be replaced simultaneously.

[0032] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
