Foreign matter prevention electric generator

Abstract

The invention relates to a foreign matter prevention electric generator which comprises a ventilating duct, an impeller assembly, an induction motor assembly, an impurity prevention assembly and a transmission assembly. The impeller assembly is mounted in the ventilating duct and comprises an output shaft, and the output shaft is connected with the induction motor assembly. The impurity prevention assembly comprises a blocking impeller, an annular fixing frame is arranged on the edge of the blocking impeller, and the blocking impeller is rotatably arranged at an air inlet of the ventilating duct through a thin-wall bearing which is arranged on the periphery of the fixing frame. The blocking impeller comprises a plurality of blocking rods which are arranged in an annular array mode relative to the axis of the output shaft of the impeller assembly, and an annular isolation net is arranged from the fixing frame of the blocking impeller to the middles of the blocking rods. The transmission assembly enables the fixing frame and the impeller assembly to make reversing rotation movement under the driving of the output shaft.

Description

Technical field [0001] The invention relates to an anti-foreign body generator, belonging to the field of power generation equipment. Background technique [0002] In some office buildings and factories, in response to the national call for energy conservation and emission reduction, some wind power generation devices are often installed in some vents. The power generation devices in these use environments are different from large-scale wind turbines on the grasslands or the ocean. First of all, office buildings and factories do not have space to install such large-scale wind power equipment, and office buildings and factories are generally in densely built areas, and the driving force of wind is relatively limited. Therefore, some small wind power generation is used in office buildings and factories. Installations to improve the secondary use of energy. At the same time, the environment of office buildings and factories is different from the grassland environment. The air contai...
