Wind power generator with dual purposes of ventilation and electricity generation

Abstract

The invention discloses a wind power generator with dual purposes of ventilation and electricity generation, belonging to the technical field of new energy power supply system devices. The wind power generator mainly comprises a main engine (9), a spherical holder (8), a main shaft (6), a rack (10), a main bearing (4), a wind wheel (5), an auxiliary wind wheel (2), an auxiliary wind inlet (3), an engine base (11),a control box (12), a stop (13) and a lead (14), wherein, the main engine (9) is connected with the spherical holder (8); the main shaft 6 is fixed on the rack (10); the wind wheel (5) and the auxiliary wind wheel (2) are supported by the main bearing (4) at the upper end of the main shaft (6) and the top of the main shaft (6) is connected with the auxiliary wind inlet (3); the rack (10) is sleeved on the engine base (11). The wind power generator is characterized in that a ventilation cooling device and an automatic monitoring and speed regulating system are arranged in the main engine, thus solving the problems of demagnetizing and aging of permanent magnets caused by temperature rise and the problem that the wind power generator is difficult to start at low wind speed or is low in generating efficiency, unstable in output and big in noise at high wind speed. The weight and volume of the generator are decreased and the manufacturing cost is dramatically lowered. The product not only has huge market potential but also has multiple purposes including ventilation and illumination free of charge, thus having the effect of half effort with double results in the case of remitting the urban power consumption which is steadily on the increase at present.

Description

technical field [0001] The invention relates to a dual-purpose wind power generator for ventilation and power generation, which belongs to the technical field of new energy, and in particular to a wind power generation device integrating building ventilation and power generation. Background technique [0002] In the prior art, the wind power generator is only limited to the power generation function, and does not integrate the indoor ventilation and power generation functions in order to exert greater energy-saving potential and application range. In this regard, I have been involved in the patent No. 200820084371.2, "Unpowered Ventilator Fan That Can Generate Power", because the wind speed in nature is always changing, so designing and selecting an excellent generator to match it is to realize the above-mentioned One of the important conditions of the goal. [0003] In order to make this new energy project of wind power generation more widely used and benefit mankind, it i...
