Although the paddle-floating windmill of this structure can realize the rotation direction of the paddle plate in the variable wind direction, and has a high utilization rate of wind energy, the structure of the windmill is not high enough because of its chassis strength, and the transmission mechanism adopts Cylindrical gear transmission mechanism, in order to make the windmill have high power, it must be achieved by increasing the size of the gear, which not only increases the cost, but also has a very limited increase in power. In addition, large-sized gears are not conducive to the transmission mechanism. It is closed, and at the same time it cannot guarantee a good lubrication effect, which will inevitably affect the normal use of the windmill, which will also cause unsafe use.

Utility model content

In order to overcome the drawbacks in the above-mentioned prior art, the utility model provides a paddle-turning windmill with a bevel gear transmission mechanism, which can not only make full use of wind energy, but also increase the size of the paddle board, thereby improving Windmill power.

The positions of the sizing boards on the transverse axes are intersecting. The paddle board is made of canvas with a frame.

Compared with the prior art, the beneficial effects of the utility model are:

In order to achieve the application efficiency of the pumping type windmill, it is necessary to manufacture a large windmill with a large area of pumping, so as to reduce the cost and improve its application value. If the paddle type windmill with a cylindrical gear transmission mechanism is made into a large one, it must be realized by increasing the size of the gear. The large gear is not only difficult to manufacture, but also uses a lot of materials, and the increased weight is essentially increased at the same time. On the rotating parts, the increased centrifugal force cannot be ignored. Therefore, it is very limited to increase the power of the windmill by increasing the size of the gear. In addition, the large gear is not conducive to the sealing of the transmission mechanism and the guarantee of reliable and effective lubrication. The fanning type windmill of the utility model adopts conical gears as the transmission mechanism, wherein the rotor gears are designed as two sets of conical gears connected by shafts, so that the length of the gear shaft can be lengthened, and the size of the fanning board can be correspondingly increased. It is convenient to make a high-power windmill.
