Multiple wind wheel strong generator

Abstract

The invention relates to a kind of wind-driven geenrator, especially relate to a multi-wind wheels forceful generator. That can generate electricity with the wind force above grade 1.5. This inventionis: a multi-wind wheels forceful generator, including the pillar, the generator, the wind wheel, the level rotary disc is fixed on the pillar, and connected with the main frame firmly; the connectingwheel and the main wind-wheel are fixed on the shaft of generator; on the main frame there is bearing assembly, the shaft of the bearing assembly is connected firmly with the auxiliary wind-wheel andthe auxiliary wind-wheel connecting wheel; the connecting wheel is connected to the auxiliary wind wheel connecting wheel by transmission belt. The drawing electric wire on the generator is guided out by wire. Advantages are effects: the invention uses several wind-wheels, passes on the rotary square to the generator shaft. This new structure is bound to raise efficiency several-fold or hundred-fold. This wind-driven generator can keep generating electricity in a big area with wind force of grade 1.5.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a powerful generator with multiple wind rotors capable of generating electricity with wind force above level 1.5. Background technique [0002] As early as 30 years ago, wind power generators were popular in Europe and the United States, but they were all column type single wind wheel structures. With the strengthening of people's awareness of environmental protection, green power generation has been widely valued by all countries in the world. Therefore, the diameter of wind turbines ranging from 10 meters to 30 meters Large wind turbines have been used in a wide range of applications. However, due to the large diameter of the wind wheel, the linear velocity difference between the small diameter position of the blade near the center of the circle and the rotating large outer diameter is too large. The diameter is 30 meters at 40 revolutions per minute, and the linear velocity at 1 meter...

Problems solved by technology

However, due to the large diameter of the wind wheel, the linear velocity difference between the small diameter position of the blade near the center of the circle and the rotating large outer diameter is too large. The diameter is 30 meters at 40 revolutions per minute, and the linear velocity at 1 meter and 15 meters from the center is 25 respectively. m / min and 3768 m / min (speed at the large diameter), which are much higher than the wind speed, so the parasitic resistance generated on the upper end of the actual wind blade restricts the efficiency of wind turbine power generation

[0003] Although US20040047733A1 of the United States discloses a generator with multiple wind rotors, the wind rotors are connected in series on the shaft and then transmitted to the generator at a variable speed, and a plurality of wind rotors are connected in series on one shaft. The wind resistance, that is, the beam flow resistance, doubles the aerodynamic stirring effect, which just reduces the rotational torque of the wind energy impeller and reduces the wind energy efficiency. When the wind impeller placed at the front end of the windward direction is the first wind receiving impeller, its rotation torque is greater than that of the rear The number of impellers at the back is affected by the vortex flow of the front rotating impeller, and the number of revolutions drops sharply. The torque becomes smaller as it goes to the rear. , it is an inescapable load for the front windward impeller, so it is not that the more impellers in series, the greater the rotational torque, but the rear impeller is affected by the eddy current and the rotational torque decreases, and the load of the front windward impeller is more, so in the same axis Wind rotors connected in series have a great influence on each other, so this kind of series aerodynamic structure does not have the possibility of improving aerodynamic efficiency in principle
