Permanent-magnet fan blade and wind power generation integrated machine

Abstract

The invention relates to a permanent-magnet fan blade and wind power generation integrated machine, which comprises a vertical shaft fan made of permanent material. The shaft of the fan is arranged between an upper fan cover and a lower fan base. A ring structure formed by a first soft magnet and a second magnet is respectively arranged on the internal side of the fan cover and the internal side of the fan base. A saw-toothed blade is inward arranged on the fan. The first soft magnet and the second soft magnet protrude outward in the two angle directions of the fan cover and the fan base and are extended upward and downward to break over a magnet circuit. The polarities of the upper end and the lower end of the fan blade of the vertical shaft fan are different. Coils are arranged on the fan blade. An upper edge and a lower edge with the same shape as the saw-toothed blade are respectively arranged at the upper end and the lower end of the fan blade. The vertical shaft fan, the first soft magnet and the second soft magnet can form a closed main magnetic circuit with two small air gaps. When the fan rotates, magnetic flux in the main magnetic circuit is varied, the magnetic flux of each coil is correspondingly increased or reduced and AC electromotive force is produced. The invention has the advantages of compact structure, convenient installation, small volume, strong applicability, energy saving and environmental protection.

Description

technical field [0001] The invention relates to an integrated wind power generation machine, in particular to a permanent magnet fan blade wind power generation integrated machine suitable for wireless sensor networks and distributed small systems. Background technique [0002] With the emergence and development of wireless sensor networks, distributed small systems and the Internet, the problem of power supply for the nodes that are scattered everywhere and make up the above systems has become a difficult problem. These nodes generally need to have their own independent power supply devices, and batteries are often used. However, the power of the battery is limited. Even if the wireless sensor node is designed with low power consumption, it can only last for several months. The life of the battery becomes the bottleneck of the life of the node. secondary pollution is bound to become a major threat to the environment. Therefore, it is imperative to use new energy sources t...
