PURPOSE: An aerogenerator equipped with a coil spring power-train is provided to rotate an impeller using weak wind by delivering the power using a method in which a drive winding spring and a driven winding spring are meshed. CONSTITUTION: An aerogenerator comprises a case(200), an impeller(210), a generator(220), a LED(230), a drive winding spring(240) and driven winding spring(250). The impeller is mounted on the front side of the case to rotate and has a light-passing hole(218) on the center part. The generator is built in the case. The LED is arranged on the location which faces the light-passing hole of the impeller and is electrically connected to the generator The drive winding spring has a hooking part on one side. The drive winding spring is installed on the circumference of an impeller rotary shaft(216). The driven winding spring has a hooking part on one side. The driven winding spring is installed on the circumference of a generator rotary shaft(226). The hooking part is interlocked in the hooking part of the drive winding spring. The torque of the impeller is delivered to the generator rotary shaft. |
