Parasitic turbine generator

Abstract

The invention relates to a parasitic turbine generator, and belongs to the technical field of new energy and power generation. The parasitic turbine generator mainly comprises a machine shell, a machine cover, an inner ring frame, an outer ring frame, a wheel shaft, a movable magnet, a fixed magnet, a vibrating reed, a fixed sheet, a coupler, a circuit board and a sensor, the machine shell is provided with an outer shell and an outer shell shaft sleeve, the machine cover is composed of a cover plate and a machine cover shaft sleeve, and the wheel shaft is composed of a left half shaft, a right half shaft and a turntable embedded with the movable magnet; the outer ring frame is provided with a ring cavity and a ring groove embedded with a fixed magnet, and the inner ring frame is provided with a counter bore and a ring cavity provided with an annular fixing piece on the bottom wall; and the machine cover and the wheel shaft are installed on the machine shell, fan blades of the coupler are installed at the end of the left half shaft, the machine cover presses the vibrating reed in the machine shell through the inner ring frame and the outer ring frame, the vibrating reed is located between the inner ring frame and the outer ring frame, the circuit board is installed on the machine shell, and the sensor is installed on fan blades or a fan main shaft. During working, the fan main shaft and the wheel shaft rotate reversely, moving magnets and vibrating pieces alternately get close to or away from the moving magnets, the moving magnets are alternately in contact with or separated from the fixing pieces on the two sides, and then mechanical energy is converted into electric energy.

Description

technical field [0001] The invention belongs to the technical field of new energy and power generation, and in particular relates to a parasitic turbine generator, which provides real-time power supply for a wind power generator blade monitoring system. Background technique [0002] The blade is the key component of the wind turbine to receive wind energy and convert it into rotational motion, which directly affects the reliability and service life of the generator. Because wind turbine blades usually work in harsh natural environments, and their structural size, weight and working load are large, in addition to being damaged by irresistible natural disasters such as lightning strikes and earthquakes, natural corrosion, wear and fatigue stress, etc. The resulting blade damage is also unavoidable. Practice has shown that one-third of the accidents that occur during the operation of wind turbines are caused by blade damage, so the health monitoring of wind turbine blades is u...

AI Technical Summary

Problems solved by technology

[0003]With the increasing length of wind turbine blades and the overall number of wind turbines, the previous method of relying on manual regular inspection and maintenance can no longer meet production needs

Therefore, various forms of wind turbine blade health status monitoring methods and corresponding self-powered generating devices have been proposed. However, due to the constraints of existing self-powered generating The online monitoring technology of blades has not been widely used, especially there is no online monitoring system based on self-powered technology
