Solar boiler system {SOLAR BOILER SYSTEM}

The present invention relates to a solar light boiler system.

In general, solar heat collecting plates are efficiently combined and arranged in hot water and heating systems using solar heat, thereby maximizing solar heat collecting efficiency.

As shown in FIG. 1, a conventional solar energy utilization apparatus as a boiler fuel source for heating uses a difference in electromotive force applied to sunlight incident on an amorphous panel (not shown) to generate a DC power A direct current control unit 2 for supplying the direct current power of the solar cell module unit 1 to the direct current control unit 3 for preventing reverse current of the power source, A solar cell protection unit 5 for preventing the solar cell from being broken due to the reverse current of the unexpected current of the inverter 4, An alternating current regulating switch 6 for regulating the overcurrent of the alternating current power applied from the protection unit 5, a generation watt hour meter 7 for measuring the amount of power output from the alternating current regulating switching unit 6, To each household's heating system ( 9 for the boiler.

Hereinafter, the operation of the solar energy utilization apparatus as the heating source boiler fuel source according to the related art will be described.

First, when solar light is incident on the amorphous panel of the solar cell module 1, DC power is generated due to the difference in electromotive force, and this DC power is appropriately controlled by the connector control unit 2 and the direct current control switching unit 3 Is applied to the solar cell protection unit 5 which is adjusted to be applied to the inverter 4 and converted into an AC power source, and then the solar cell is prevented from being destroyed by an external overcurrent and a backward flow of an unexpected current.

Thereafter, the AC power outputted from the solar cell protection unit 5 is measured by the generated watt-hour meter 7 via the AC control switching unit 6 and then transmitted to the heating unit 9).

However, the method and apparatus for utilizing solar energy as a heating source for a boiler fuel source according to the related art can not operate normally when the solar heat can not be properly received due to weather, especially snow, rain, So that the power can not be generated.

Also, on a clear weather day, a larger amount of electric power is produced than the amount of electric power required for each household's heating apparatus. In the past, however, the surplus electric power could not be utilized properly, thereby failing to maximize the function as an alternative energy.

On the other hand, the generated electric power connected to the conventional heat sink structure is charged in the battery. In the night or cloudy days when there is no sunlight, the electric power is not charged, so that the battery may generate sulfate.

When the sulfate is fixed to the electrode plate of the battery, there is a problem that the electricity generating area is reduced and the life of the battery is shortened.

In addition, conventionally, the direct current power generated by the sunlight is converted into the alternating current power by the inverter 4 and used, so that the configuration of the separate inverter 4 is complicated and the installation cost is increased .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a solar-powered boiler system capable of collecting sunlight and absorbing a large amount of sunlight while rotating the solar- .

It is another object of the present invention to provide a solar-powered boiler system in which a household power source is charged in the absence of sunlight to prevent the occurrence of non-charging time, thereby preventing the sulfate from sticking to the battery.

It is still another object of the present invention to provide a solar boiler system capable of heating a boiler by using a separate heating means in the absence of sunlight.

According to another aspect of the present invention, there is provided a solar battery module including a solar battery unit for absorbing sunlight to generate a power source, a power controller for regulating power generated by the solar battery unit, An external power input unit that is supplied to the solar battery unit and to which external power supplied to the battery is input; an external power input unit that receives external power input from the external power input unit; And a control box for controlling the solar battery section, the power controller, and the switching section.

According to the present invention, since the solar panel is rotated along the direction of the sun and collects sunlight, there is an advantage that a large amount of sunlight can be absorbed.

In addition, the present invention is advantageous in that when the solar light is absent, the household power source is charged to prevent the time for not being charged, thereby preventing the sulfate from sticking to the battery.

Further, the present invention has an advantage that the boiler can be heated by using a separate heating means in the absence of sunlight.

At this time, the motor driving unit 19e drives the driving motor 15 to correct the motor driving unit 19e by a different value.

When the driving motor 15 is driven and no difference in sensing values sensed by the plurality of solar sensors 17 is generated, the motor driving unit 19e stops driving the driving motor 15.

When the pressure of the water tank 41 is raised by the heating of the heater 43 and the weight 49b rises along the pressure discharge pipe 49a due to the raised pressure, the raised pressure is transmitted to the pressure discharge hole 49e To the outside. Then, when the raised pressure is discharged and the pressure of the water tank 41 is lowered, the weight 49b is lowered and supported by the weight supporting step 49d. At this time, the weight of the weight 49b may be adjusted so as to discharge an abnormality of pressure that the water tank 41 can withstand.
