Wind power generating integrated machine with coil fan blade

Abstract

The invention provides a wind power generating integrated machine with a coil fan blade, which comprises a vertical shaft fan made of non-magnetic materials. A shaft is arranged between a fan cover at the upper part and a fan seat at the lower part, circular ring-shaped permanent magnets are respectively arranged at the inner sides of the fan cover and the fan seat, the inner side face of each permanent magnet is composed of N poles and S poles which are uniformly distributed in a spaced manner, and circular ring-shaped magnetic-conduction flexible magnets are respectively arranged between the permanent magnets and the fan cover or the fan seat. Fan blade upper and lower rims made of flexible magnetic materials are respectively arranged at the upper and lower ends of the fan blade of the verticals shaft fan, the fan blade upper and lower rims are protruded along the two sides and are parallel to the permanent magnets, and coils are respectively wound in grooves of the fan blade upper and lower rims. The N poles, the fan blade upper rim or the fan blade lower rim, the S poles and the magnetic-conduction flexible magnets can form closed main magnetic circuits with air gaps. When the fan is in rotation, magnetic flux of each coil can be increased or decreased along with the changing of the magnetic flux in each main magnetic circuit, so as to generate AC electromotive force. The wind power generating integrated machine has the beneficial effects of compact structure, small volume, high energy conversion rate, energy saving and environmental protection.

Description

technical field [0001] The invention relates to an integrated wind power generation machine with fan blades with coils, in particular to an integrated wind power generation machine with fan blades with coils which is 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 i...
