Example Embodiment

[0026] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0027] Such as figure 1 As shown, the present invention is an efficient anti-foreign object discharge machine. The generator includes an air guide tube 6, an impeller assembly, an induction motor assembly, and an anti-miscellaneous assembly. The impeller assembly is installed inside the air guide tube 6, so The impeller assembly includes an output shaft 4, the output shaft 4 is connected with the induction motor assembly, the impeller is driven by the air flow blown into the air guide tube 6 to make the induction motor assembly generate electricity, and the anti-miscellaneous assembly includes a barrier impeller. An annular fixed frame 5 is provided on the edge of the b...

Abstract

The invention relates to an efficient foreign-body-proof electric generator. The electric generator comprises a ventilating duct, an impeller assembly, an induction motor assembly and an impurity-proof assembly. The impeller assembly is installed inside the ventilating duct and comprises an output shaft, and the output shaft is connected with the induction motor assembly. The impurity-proof assembly comprises a grid impeller, an annular fixing frame is arranged at the edge of the grid impeller, the grid impeller is arranged on an air inlet of the ventilating duct through a thin-wall bearing in a rotary mode, the thin-wall bearing is arranged on the periphery of the fixing frame, the grid impeller comprises a plurality of grid pieces which are arranged relative to the axis of the output shaft of the impeller assembly to form an annular array and an annular isolation net is arranged from the fixing frame of the grid impeller to the middles of the grid pieces; the bending direction of each grid piece is opposite to the bending direction of each blade in the impeller assembly, the isolation net comprises a plurality of isolating rings which are fixed to the grid pieces with the axis of the output shaft as the circle center, and the diameters of the isolating rings gradually increase from the center of the grid impeller to the outside.

Description

technical field [0001] The invention relates to an efficient anti-foreign matter discharger, which belongs to the field of power generation equipment. Background technique [0002] In some office buildings and factories, in order to respond to the national call for energy conservation and emission reduction, some wind power generation devices are often installed at some vents. The power generation devices in these environments are different from large-scale wind power generation units on grasslands or oceans. First of all, office buildings and factories do not have space to install such large-scale wind power generation equipment. Furthermore, office buildings and factories are generally located in densely built areas, and the driving force of the wind is relatively limited. Therefore, some small wind power generation equipment will be used in office buildings and factories. device to improve the secondary utilization of energy. At the same time, the environment of office bu...
