Generating device of ventilation system

Abstract

The invention provides a generating device of a ventilation system, which comprises a wind inlet unit, a generating unit, a wind outlet unit and a control unit, wherein a plurality of generating fan blades are arranged at the relatively open position in the pipeline of the wind inlet unit and the wind outlet unit; the generating fan blades of the wind inlet unit are finally connected with a main speed changer together through respective speed changers, and the generating fan blades of the wind outlet unit are finally connected with the main speed changer together through respective speed changers; each speed changer is connected with a respective generator; and the direct-current electric quantity generated by each generator can be stored by a power storing device and can be also used directly. The invention has the obvious effects that the wind inlet unit and the wind outlet unit of the ventilation system are provided with the generating fan blades, thus the potential of the ventilation system is fully used, and the ventilation system can not be influenced. The generating device of the ventilation system can be used for emergency protection of motors under the condition of instantpower failure.

Description

technical field [0001] The invention relates to a power generating device, in particular to a power generating device for a ventilation system. Background technique [0002] We convert the kinetic energy of the wind into mechanical energy, and then convert the mechanical energy into electrical energy, which is wind power generation. The devices required for wind power generation are called wind turbines. This wind turbine can be roughly divided into three parts: the wind rotor (including the tail rudder), the generator and the iron tower. Because the speed of the wind wheel is relatively low, and the size and direction of the wind force often change, which makes the speed unstable; therefore, before driving the generator, a gear box must be added to increase the speed to the rated speed of the generator. Add a speed regulating mechanism to keep the speed stable, and then connect to the generator. In order to keep the wind rotor aligned with the wind direction to obtain ma...

AI Technical Summary

Problems solved by technology

[0004] As an indoor air intake and return air device, the ventilation system can transfer a considerable amount of wind power. If it can be used in a small wind power generation device, not only can the energy be utilized, but it can also be used For emergency power needs, however, the technology used is not very mature and needs continuous improvement
