Description

  The present invention relates to a generator using a battery as a power source.

  Conventionally, natural energy such as solar power generation and wind power generation can be used as an independent power source only by storing and stabilizing electricity in a storage battery.

  In order to convert natural energy into a stable commercial power source, a battery charge / discharge control device and a DC / AC converter are required, which is a complicated and expensive device.

  Conventional engine generators must be refueled regularly. Natural energy such as solar power generation and wind power generation can only be used as an independent power source by storing and stabilizing electricity in a storage battery, but in order to convert it into a stable commercial power source, charging and discharging the battery A control device and a DC / AC conversion device are required, resulting in a complicated and expensive device.

  In order to solve such a problem, the present invention provides a small generator that is stable for a long time, low in cost, and simple.

  The apparatus configuration includes a main battery, a charge / discharge switching device, a DCAC converter, a motor, a load reduction rotor, a flywheel generator, a belt, a power conversion control panel, a control control panel, and an ACDC converter.

  In the present invention, the flywheel generator is rotated by rotating the motor with the main battery. The main battery is charged with the power generated by the flywheel generator. The main battery is composed of three or more batteries, and charging and discharging to the load are repeated in order. The output of the flywheel generator is converted into power and connected to a load via a control panel.

  The generator used in the present invention is a flywheel generator, and stable power generation is possible by a flywheel function.

  According to the present invention, it is not necessary to supply fuel like an engine generator, and a simple automatic small generator can be provided at a lower cost than a method of storing natural energy in a battery and converting the power.

It is a block diagram of the automatic small generator in embodiment of this invention. It consists of a main battery, charge / discharge switcher, DCAC converter, motor, load reduction rotor, flywheel generator, belt, power conversion control panel, control control panel, and ACDC converter. It is sectional drawing of the flywheel type generator of this invention. It is a charge / discharge switching timing diagram of the main battery of the present invention.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments according to the invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of an automatic small generator according to the present invention. The automatic small generator includes main batteries 100, 101, 102, charge / discharge switching units 103, 104, 105, a DCAC converter. 106, a motor 107, a load reducing rotor 108, a flywheel generator 109, a belt 110, a power conversion control panel 111, a control control panel 112, and an ACDC converter 113.

  The main battery A100 is connected to the DCAC converter 106 via the charge / discharge switcher A103. The main battery B101 is connected to the DCAC converter 106 via the charge / discharge switcher B104. The main battery C102 is connected to the DCAC converter 106 via the charge / discharge switcher C105. The DCAC converter 106 is configured to be supplied with electricity from one of the main battery A100, main battery B101, and main battery C102 switched by the charge / discharge switchers 103, 104, and 105.

  The DCAC converter 106 is connected to a motor 107, and the motor 107 rotates using one of the main battery A100, the main battery B101, and the main battery C102 as a power source.

  The motor 107 is connected to a load reducing rotor 108 and a flywheel generator 109 by a belt 110. When the motor 107 rotates, the load reducing rotor 108 and the flywheel generator 109 rotate simultaneously. The load reducing rotor 108 has an effect of maintaining the rotational force with a flywheel.

  The output of the flywheel generator 109 is connected to a load 114 and an ACDC converter 113 through a power conversion control panel 111 and a control control panel 112 for AC power. The output of the ACDC converter is connected to the main batteries 100, 101, 102 via charge / discharge switchers 103, 104, 105. The electric power generated by the flywheel generator 109 is supplied to the load 114 and simultaneously used for charging the main batteries 100, 101, 102. The charging / discharging switchers 103, 104, and 105 are configured to charge a battery that is not used for driving the motor.

  The flywheel generator 109 has a function of making the output current larger than the input current. According to the experiment, surplus power of 15% to 18% of the consumed load power is generated. This surplus power can be charged to the main batteries 100, 101, 102.

  FIG. 2 is a cross-sectional view of the flywheel generator 109. The rotating body 201 and the rotating shaft 207 are fixed inside the flywheel generator main body 200 so that the flywheel generator main body 200 can rotate freely. The coil (outer ring portion) 204 is fixed inside the flywheel generator main body 200, and the coil (inner ring portion) 205 is fixed outside the silicon holder 206. The silicon holder 206 is fixed to the flywheel generator body 200.

  A magnet (outer ring portion) 202 is fixed to the outside of the rotating body 201, and a magnet (inner ring portion) 203 is fixed to the inside. When the rotating body 201 rotates, the magnet (outer ring portion) 202 and the magnet (inner ring portion) 203 rotate simultaneously.

  With the above configuration, when the rotating body 202 rotates, the magnetic field changes with respect to the coil, and a current flows through the coil.

  FIG. 3 is a charge / discharge switching timing diagram of the main battery. When the main battery A100 is used for driving the motor, the main battery B101 is fully charged and the main battery C102 is being charged. When the main battery B101 is used for driving the motor, the main battery C102 is fully charged and the main battery A100 is being charged. When the main battery C102 is used for driving the motor, the main battery A100 is fully charged and the main battery B101 is being charged. These switching operations are performed automatically while monitoring the battery voltage. When the voltage of the main battery becomes 22V or less, the discharge is completed and the battery is switched to charge.

  By switching the main battery, the power can be supplied constantly and stably.

  In the present invention, for example, it is possible to increase the voltage by connecting a plurality of 12V main batteries in series, for example, 24V, 36V, 48V, etc., and configuring three main batteries.

  In addition, this invention is not limited to the said embodiment, The structure and form in the range which can achieve the objective of this invention are also included.

Examples of the automatic small power generator according to one embodiment of the present invention will be described below.
When installing an earthquake observatory, etc. in a place without electrical equipment, it is necessary to operate measuring instruments, recorders, communication devices, etc., but using this generator will supply stable power for a long time. It is environmentally friendly because it does not emit exhaust gas.
