Title: Non-interruptible electric power supply system with sound power generation

Description:
TECHNICAL FIELD 
     The present invention relates to a non-interruptible electric power supply system, more specifically to a non-interruptible electric power supply system with sound power generation which converts a certain level or higher of noise generated from a motor, etc., which is mainly used in an industrial site, into electricity, thereby increasing power generation efficiency. 
     BACKGROUND ART 
     Korean Patent No. 10-0964597 (Uninterrupted power supply) discloses, “An uninterrupted power supply (UPS) includes a battery, a balance node, a first power converting circuit, and a second power converting circuit. The battery stores energy. The balance node is connected to an AC input power through a switch. The first power converting circuit is connected to the balance node, battery and load, and adjusts a voltage level applied to the load by charging and discharging the energy of the battery. The second power converting circuit is connected to the balance node and battery, and adjusts current inflowed into or outflowed from the balance node and current inflowed into or outflowed from the load by charging and discharging the energy of the battery.” 
     However, the conventional non-interruptible electric power supply system charges power into the battery at ordinary time and discharges the power charged in the battery outside in an emergency. Thus, energy efficiency thereof is not good. 
     Furthermore, in order to extend the dischargeable time in case of an emergency of the non-interruptible electric power supply system, energy efficiency or battery capacity needs to be increased. However, recently, there is a limit in terms of structure, and battery-related costs are excessively increased for increasing the battery capacity unlimitedly.

     BEST MODE FOR CARRYING OUT THE INVENTION 
     Hereinafter, the present invention will be explained in detail with reference to the attached drawings. 
     For reference, the present invention relates to a non-interruptible electric power supply system with sound power generation. However, a power generation circuit and a circuit for supplying non-interruptible electric power may be fully implemented with the currently published technologies alone, so the detailed description thereof will be omitted. The main constitution of the present invention, which is the constitution of sound collection, will be explained in detail. 
       FIG. 1  is a block diagram illustrating a schematic constitution of a non-interruptible electric power supply system with sound power generation according to the present invention. The non-interruptible electric power supply system includes a battery charger  11  which charges power into an internal battery from a household power source or an industrial power source, and discharges the power charged in the internal battery after the supply of the household power source or industrial power source is discontinued. 
     In this case, as illustrated in  FIG. 4  and  FIG. 5 , the non-interruptible electric power supply system includes a noise generator  1200  which gathers a noise generated by a normal driving of an industrial apparatus not to be scattered in all directions. 
     Additionally, the non-interruptible electric power supply system includes a sound power generator  12  including a vibration plate where vibration is generated by a sound collected from the noise generator  1200 , a vibration pole which is vertically fixed at an end of the vibration plate and repeats ascending and descending, and an electric converter which generates electricity from an electric field variation generated according to the ascending or descending of the vibration pole upward or downward, and an inverter  13  which converts direct current delivered from the sound power generator  12  into alternating current and outputs the alternating current. 
     A structural characteristic of the sound power generator  12  collecting the sound to be used as a power generation source will be explained in detail. 
       FIG. 2  is a cross-sectional view illustrating a main part of a sound power generator of a non-interruptible electric power supply system according to the present invention.  FIG. 3  is an exploded perspective view illustrating the disassembly of constitutional elements of  FIG. 2 . 
     Referring to  FIG. 2  and  FIG. 3 , a sound power generating body  120  includes a vibration plate  128  which gathers a noise collected and vibrates due to the noise. When an upward and downward movement is made as the vibration plate  128  vibrates, a vibration pole  127  fixed at an end of the vibration plate moves upward and downward. 
     As such, the upward and downward movement of the vibration pole  127  triggers a magnetic field variation due to current passing through a coil  125  which is wound on an external circumference of an annular guide  126  which surrounds the vibration pole  127 . The coil  125  allows electricity to flow, to form a magnetic field by the current. 
     An induced electromotive force is generated between magnetic fields of a magnetic  124  arranged at an outer edge of the sound power generating body, which is used as a power generation source. According to the necessity, the vibration pole  127  may be made of a permanent magnetic to increase the induced electromotive force. 
     Meanwhile, a case  121  is electrically blocked from outside, to minimize an influence of an external electric field or an external magnetic field. A main body  122  has a ‘T’-shaped cross-section so as to support each constitutional element. 
     A support plate  123  has a circle shape which opens in the middle so as to support the magnetic  124  and coil  125  inside, and includes an electrical connecting part  129  for outputting electricity generated. 
     The sound power generating body  120  with the above-mentioned constitution may be carried out as in a first embodiment illustrated in  FIG. 4 , or may be carried out as in a second embodiment illustrated in  FIG. 5 . The sound power generating body may be properly selected according to a situation of a place of business. 
       FIG. 4  is a cross-sectional view illustrating an arrangement of a sound power generator of a non-interruptible electric power supply system according to the first embodiment of the present invention.  FIG. 5  is a cross-sectional view illustrating an arrangement of a sound power generator of a non-interruptible electric power supply system according to the second embodiment of the present invention 
     For reference, for the first and second embodiments, it is proper in terms of efficiency to arrange the noise generator  1200  and sound power generating body  120  to be adjacent to each other. First, second, third and fourth vacuum walls  1211 ,  1212 ,  1213  and  1214  are provided outside. In this case, a gap between the first, second, third and fourth vacuum walls  1211 ,  1212 ,  1213  and  1214  is in a vacuum state, and an innermost and an outermost thereof are not in a vacuum state. 
     Referring to  FIG. 4 , by arranging the sound power generating bodies  120 A and  120 B at a lateral end or a lower end of a rotational axis of a noise source like a motor, which is a main noise source in an industrial site, efficiency of noise collection may be increased while a worker may not hear that noise. 
     Referring to  FIG. 5 , an outer case of the sound power generating body  120  includes a plurality of holes  200 A,  200 B,  200 C and  200 D, and an outer case of the noise generator  1200  includes a plurality of holes  300 A,  300 B,  300 C and  300 D, so as for the noise to be distributed inside, without leakage outside.
