Description

Non-contact air generation system using non-power air in/out scheme

The present invention relates to a power generation system, and more particularly, to a non-contact power generation system using a non-powered air suction method.

In the non-contact power generation technology, a magnet generated between a permanent magnet and a coil between a rotating part and a fixed part is mounted by attaching a permanent magnet to a rotating part and a coil to a fixed part, or, conversely, a coil to a rotating part and a permanent magnet to a fixed part. It has a configuration that generates an induced current through a change in the line speed.

Such non-contact power generation technology has been applied to many fields due to advantages such as almost no noise generation and free from damage or wear of parts, so that it can be used permanently.

However, the conventional non-contact power generation technology has a problem in that power generation efficiency is relatively low because it is mainly applied to power such as bicycles.

In addition, since power generation is performed using only power, there is a problem in that power generation efficiency is deteriorated because it is not linked to other power generation such as sunlight.

Therefore, there is a need for a power generation system that increases power generation efficiency using non-power.

1 is a block diagram of a non-powered air suction non-contact power generation system 100 according to an embodiment of the present invention. Referring to FIG. 1, the non-powered air suction non-contact power generation system 100 includes a first generator 110 that generates power using a non-powered suction method, and a second power that generates power using natural power such as sunlight or wind power. It comprises a to the fourth generator (120 ~ 122), a power conversion unit 130 for supplying power by selectively using these generators.

The first generator 110 for producing electric power using the non-powered suction method is engaged with the primary gear 10 and the primary gear 10 connected to the rotation shaft 11 of the non-powered extractor 200 and rotates It includes a secondary gear 111, a power generation motor 112 for producing alternating current (AC) power by rotation of the secondary gear 111, an inverter 114 for converting the AC power to DC power, etc. Can be configured. The primary gear 10 and the secondary gear 111 may be spur gears, helical gears, or the like. In particular, the diameter of the primary gear 10 is larger than the diameter of the secondary gear 111, the secondary gear 111 rotates in proportion to the rotation of the primary gear 10.

Incidentally, the ratio of the rotational speeds of the primary gear 10 and the secondary gear 111 is amplified at a 1:N ratio. Accordingly, when the diameter of the primary gear 10 is 1 m (=100 cm) and the diameter of the secondary gear 111 is 10 cm, the revolutions (REV: revolution) and RPM (revolution per minute) are as follows.

division Diameter (cm) Length (cm) Revolution (REV) ratio RPM (rev/min) 1st gear 100 314 2×3.14×100÷2 1 round 60rpm 60 revolutions/minute Second gear 10 31.4 2×3.14×10÷2 10 turns 600rpm 600 revolutions/minute

The shaft of the power generation motor 113 is connected to the secondary gear rotation shaft 113 to produce electric power as the secondary gear 111 rotates. That is, the power generation motor 113 rotates according to the rotation of the secondary gear 111 to produce electric power. To this end, the power generation motor 113 is composed of a rotor (not shown) connected to the shaft, and a stator (not shown) installed outside the rotor (not shown). Since the structure of the power generation motor 113 is widely known, further description will be omitted.

The inverter 114 converts AC power generated by the power generation motor 113 into DC power. The inverter 114 is a voltage-type inverter, a PWM (Pulse Width Modulation) inverter is used, but is not limited thereto. The current-type inverter may be applied by modifying some components. In the case of a PWM inverter, the rectified DC voltage is simultaneously controlled using the PWM (Pulse Width Modulation) control method.

The power converter 130 is connected between the battery 140 and the inverter 114, and functions to selectively connect the first generator 110 to the fourth generator 122 to supply power to the outside. Therefore, the power conversion unit 130 may be a PCS (Power Conversion System) or the like.

The battery 140 is a place where power received from the power converter 130 is stored. Accordingly, the battery 140 includes battery cells (not shown) in series and/or in parallel, and the battery cells are used for electric vehicles such as nickel metal battery cells, lithium ion battery cells, lithium polymer battery cells, and all-solid-state battery cells. It can be a high voltage battery cell. Generally, a high voltage battery refers to a high voltage of 100V or more. However, it is not limited to this, and a low voltage battery is also possible.

Of course, the battery 140 is configured with a BMS (Battery Management System). BMS optimizes battery management to increase energy efficiency and extend life. It monitors battery voltage, current and temperature in real time and prevents excessive charging and discharging in advance to increase battery safety and reliability.

The second to fourth generators 120 to 122 perform a function of producing electric power using solar cells, wind power generation (small wind power generation), and the like. Inverters, converters, and the like may be configured in the second to fourth generators 120 to 122 to produce DC power.

FIG. 2 is a partially cutaway perspective view of the rotary ejector 200 having the rotation axis shown in FIG. 1. Referring to FIG. 2, the rotary ejector 200 includes a die 291, a fixing ring 290 for fixing the lower end of the wavy blade 280, and an upper plate for fixing the upper end of the wavy blade 280 ( 210), the upper bearing 240 installed on the upper plate 210, the upper cap 220 is covered with the upper portion of the upper bearing 240 to secure the upper plate 210 and the bearing 240, the wavy blade ( 280) the lower bearing 270 rotatably fixing the lower end of the 280, the upper bearing 240 and the lower bearing 270 is rotatably fixed by a rotating shaft 11 rotating according to the rotation of the wavy blade 280 And the like.

In the case of the non-powered rotary ejector 200, the hot air in the room rises upward and is naturally discharged, and once it starts to be discharged, the inertia is attached to the rotation, and the wavy blade 280 continuously rotates. In addition, since the inertia force of the power storage shaft 11 and the flow of the wings of the wavy blade 280 help discharge, the discharge effect is increased. In addition, when the wind blows around the non-powered rotary ejector 200, the indoor gas emission effect and the emission amount increase rapidly.

Therefore, the non-powered rotary ejector 200 is applied only for ventilation of the interior air of the building, and thus can utilize the rotational surplus force by constructing a self-power generation system using the rotational force.

The magnet 322 is installed at a predetermined interval facing the vertical rotor 321 (N pole and S pole). The rotor 321 may be formed integrally with the extended rotation shaft 301. Or it may be of a structure that is assembled to the extended rotary shaft 301. In FIG. 4, a structure in which a circular magnet is embedded is not limited thereto.

The extended rotating shaft 301 is connected and fixed to the rotating shaft 11 of the non-powered ejector 200. Therefore, the rotor 321 rotates as the wavy blades 280 of FIG. 2 rotates. That is, as the magnet 321 rotates, the coil 332 installed on the stator breaks the magnetic flux to induce electromotive force. Therefore, an organic electromotive force is generated, which is as follows.

Here, B is the magnetic flux density, L is the effective length of the coil, and V is the rotational speed.

It is possible to maximize the organic electromotive force by generating three generators up and down. That is, it is similar to the effect of driving three generators in parallel.

FIG. 5 is a front view of a parallel connection of a plurality of generators illustrated in FIG. 3. Referring to FIG. 5, the rotor 321 has a disk shape, and the magnet 322 is alternately arranged with an N-pole magnet and an S-pole magnet at an edge portion of the rotor 321.
