In one aspect, in the present invention, the term wind power refers to wind power generated by weak wind, but includes not only weak wind but also wind that can be generally used as energy.
The rotating device 20 rotates with the wind, and a blower 21 is provided on a central shaft 23 having a gear 22 formed at the lower portion thereof, and the central shaft 23 rotates by the rotation of the blower 21 and rotates the gear 22.
The gear device 30 is connected to the rotating device 20 to increase the torque of the wind force generated by the rotation of the blower 21, and the gear 31 is configured to rotate in mesh with the gear 22 of the rotating device 20. At this time, the number of teeth of the gear 31 is greater than that of the gear 22 of the rotating device 20, thereby increasing the torque as compared with the slow rotation of the gear 22 of the rotating device 20.
By configuring the gear 31 of the gear device 30 to have more teeth than the gear 22 formed on the central shaft 23 of the rotating device 20 and causing the gear 31 of the gear device 30 and the gear 22 of the rotating device 20 to rotate in mesh in this manner, torque is increased as compared with the case where the gear 22 of the rotating device 20 rotates more slowly, and power can be generated by weak wind.
The electric storage device 40 receives the torque increased by the gear device 30 to generate electric power, and stores the generated electric power, and includes a center shaft 42 connected to a rotating shaft 411 of the drive motor 41, an input gear 43, a rotating plate 44, a spiral spring 45, and a stopper 46.
The input gear 43 has a central portion coupled to the rotation shaft 411 of the drive motor 41, is formed in a disc shape, has a plurality of serrations 432 formed on an outer side thereof to receive torque from the gear device 30, has a central portion coupled to the rotation shaft of the drive motor 41 via a bearing 412, has serrations 432 formed on an outer side thereof to mesh with the gear 31 of the gear device 30, and has a recess 431 formed on a side thereof facing inward.
The rotating plate 44 is formed in a disc shape with a central portion thereof joined to the central shaft 42 and is spaced apart from the other surface of the input gear 43.
The spiral spring 45 is used to generate power and store or output the power, and has one side coupled to the central shaft 42 and the other side coupled to the rotation plate 44 through the fixing pin 451, and is wound or unwound by the rotation of the rotation plate 44. That is, the power spring generates electric power while being wound by the rotation of the rotating plate 44, stores the generated electric power while maintaining the wound state, and outputs the stored electric power by the unwinding operation.
The stopper 46 includes: a stopper wheel 462 formed in a disc shape, coupled to the rotary shaft 411, and formed in a windmill shape having a plurality of steps 461 formed inward from an outer circumferential surface; a release shaft 463 coupled to the rotation shaft 411 and rotated by the driving of the driving motor 41; an operating wheel 464 coupled to the outside of the release shaft 463; a stopper 466 having one end engaged with the step 461 of the stopper wheel 462 and the other end formed with a gear 465 so as to be rotatably coupled to the input gear 43; a pinion gear 467 coupled to the input gear 43 so as to be rotated by meshing with a gear 465 formed at the other end of the stopper 466; the link 469 is formed in a bar shape, one end of which is rotatably coupled to the operation wheel 464, and the other end of which is formed with serrations 468 for meshing with the pinion 467.
The operation state of the stopper 46 as described above will be described below with reference to fig. 5; when the input gear 43 is rotated by the gear device 30, the clockwork spring 45 is wound by the rotation of the rotating plate 44. At this time, the spring 45 is wound and generates electric power, the generated electric power is stored in a state where the spring 45 is wound, and when the release shaft 463 is rotated by the driving of the driving motor 41, the link 469 rotates the pinion 467 and the stopper 466 is disengaged from the step 461 of the stopper wheel 462, and the spring 45 is released and outputs electric power to the torque adjusting device 60.
The power output device 50 is for outputting the power stored in the power storage device 40, and includes: a flywheel 51 having a center portion coupled to the center shaft 42 and formed in a disc shape; a rotation adjuster 52 provided at a lower portion of the flywheel 51 for adjusting rotation of the flywheel 51; and a gear portion 53 which is located on one side of the flywheel 51, and whose center portion is coupled to the central shaft 42, and which is configured by a plurality of gears 531 so as to convert the rotational force transmitted through the flywheel 51 into a predetermined torque and transmit the predetermined torque to the torque adjusting device 60. At this time, the rotation adjuster 52 includes: a sensor 521 for measuring a rotational force of the flywheel 51; and a brake 522 for controlling the rotational speed of the flywheel 51 measured by the sensor 521.
The rotation speed of the flywheel 51 is measured by the sensor 521, and when the measured rotation speed of the flywheel 51 is fast, the electric power output device 50 activates the brake 522 to maintain the rotation speed of the flywheel 51 in a predetermined manner. This is an action of preventing the gear portion 53 from being damaged by the output instantaneous force when the gear portion is suddenly rotated when the stopper portion 46 performs the unwinding operation in a state where the spring 45 of the electric storage device 40 is wound.
In this way, when the electric power stored in the electric storage device 40 is output, the sensor 521 of the electric power output device 50 measures the rotation speed, and by controlling the rotation speed, the electric storage device 40 is prevented from being damaged, and a predetermined electric power can be output.
The torque adjusting device 60 is a device for adjusting the output torque transmitted from the electric power output device 50, and includes: an input portion 61 connected to the gear portion 53 of the power output device 50 and receiving a rotational force from the power output device 50; the output unit 63 is connected to the input unit 61 via a chain 62, and outputs the rotational force received from the input unit 61 to the power generation device 70.
The input portion 61 is coupled to the power transmission shaft 611 at its center portion and is configured by a plurality of gears 612 having different sizes so as to have a large diameter from one side to the other side, and the output portion 63 is coupled to the power transmission shaft 631 at its center portion and is configured by a plurality of gears 632 having different sizes so as to have a small diameter from one side to the other side. At this time, the power transmission shaft 611 of the input unit 61 is rotated by selecting any one of the plurality of gears 612 by the hydraulic cylinder by the rotational force received from the gear portion 53 of the electric power output apparatus 50, and the plurality of gears 632 of the output unit 63 are rotated by meshing the selected gear 612 of the input unit 61 with the gear 631 at the corresponding position, and output electric power to the power generation apparatus 70.
That is, the power transmission shaft 611 of the input unit 61 and the power transmission shaft 631 of the output unit 63 are configured to be coupled by selecting only a specific gear from the plurality of gears 612 and 632 by the respective hydraulic cylinders (not shown), and after the electric power output apparatus 50 analyzes the values of the torque and rotation required for power generation, and selects an appropriate gear from the plurality of gears based on the torque and the rotational force and transmits the selected gear to the hydraulic cylinder of the input unit 61, the power transmission shaft 611 automatically couples only the gear based on the command to the plurality of gears 612, and the hydraulic cylinder of the output unit 63 similarly selects and rotates the gear 632 that meshes with the gear 612 of the input unit 61, and then outputs the power via the power transmission shaft 631.
A process of generating electric power by the power generation system 10 using wind power generated by weak wind according to the preferred embodiment of the present invention is explained as follows; the blower 21 of the rotating device 20 is rotated by the weak wind, and the central shaft 23 is rotated by the rotation of the blower 21, so that the gear device 30 rotates slower than the rotation of the central shaft 23 while increasing the torque. The torque increased by the gear device 30 is input through the input gear 43 of the electricity storage device 40 rotating in mesh with the gear 31 of the gear device 30, and the rotation plate 44 winds the clockwork spring 45 while rotating by the rotation of the input gear 43, so that the power is stored in the clockwork spring 45. The spring 45 is rapidly unwound while performing an unwinding operation by driving the stopper 46 of the accumulator 40, and at this time, rotates together with the flywheel 51 of the power output device 50, the rotation speed of the flywheel 51 is measured by the sensor 521, and the rotation speed is adjusted by the brake 522 to rotate the flywheel 51 at a predetermined speed. The power transmitted while the flywheel 51 rotates at a prescribed speed is increased by the gear portion 53, and is stably rotated by the plurality of gears 612, 632 of the torque adjusting device 60 to be supplied to the power generation device 70.
As described above, the power generation system using wind force generated by weak wind according to the preferred embodiment of the present invention is illustrated in the above description and the drawings, but these are merely examples, and those skilled in the art to which the present invention pertains will appreciate that various changes and modifications can be made without departing from the scope of the technical idea of the present invention.
