[0003] However, the traditional vertical axis windmill cannot effectively utilize the return air after being placed for use, and the wind blades are easily disturbed by the outside world, resulting in large wind resistance and low power generation efficiency. Utility Model Content

[0004] In order to increase power generation efficiency, the present application provides a vertical axis return air high efficiency wind turbine.

[0005] The present application provides a vertical shaft return air high-efficiency wind turbine, which adopts the following technical solution:

[0007] By adopting the above technical solution, after the mounting base is placed, the return air utilization device can be driven to move by the driving assembly, and the angle of the return air utilization device can be adjusted so that the return air utilization device faces the return air. The return air utilization device receives the return air and guides it to the blades to blow the blades, thereby effectively increasing the rotation speed of the blades and increasing the power generation efficiency. The return air utilization device can also block part of the external turbulence on the blades, further increasing the power generation efficiency.

The adjusted return air box absorbs the external return air from the air inlet, passes it into the return air box and flows to the air outlet for discharge. The air discharged from the air outlet will blow directly on the fan blades to increase the speed of the fan blades.

[0010] Preferably, the air inlet is arranged in a flared shape.

[0011] By adopting the above technical solution, the return air can easily enter the return air box through the expanded air inlet.

[0012] Preferably, the return air box is installed with a first speed regulating component and a second speed regulating component for regulating the rotation speed of the blades.

[0017] By adopting the above technical solution, the second speed regulating motor is electrically connected to the external power supply. When the gas flow rate is too fast, the second speed regulating motor is started, and the shaft of the second speed regulating motor rotates. The rotation of the shaft of the second speed regulating motor will drive the driving gear to rotate, and the rotation of the driving gear will drive the driven gear to rotate. The rotation of the driven gear will drive the second rotating shaft to rotate, and the rotation of the second rotating shaft will drive the rotating gear to rotate. The rotation of the rotating gear will drive the moving rack to move, thereby moving the second wind shield to block the air inlet, adjusting the wind speed blowing on the blades, and thus adjusting the rotation speed of the blades.

The rotation of the shaft of the transposition motor will drive the transposition gear to rotate, and the rotation of the transposition gear will drive the driving gear to rotate. The rotation of the driving gear will drive the connecting seat to rotate, and the rotation of the connecting seat will drive the return air box to rotate, thereby realizing the movement of the return air box.

[0020] Preferably, the return air box is provided with an avoidance groove for avoiding the blades.

[0021] By adopting the above technical solution and setting the avoidance groove, the return air box can set a part of the blade cover inside the return air box, effectively reducing the influence of external disturbance on the blade.
