In general, a solar cell used in a solar generator, when solar light is irradiated to a solar cell composed of a semiconductor PN junction generates electromotive force by the photovoltaic effect, the current flows to the load connected to the outside.

These solar cells have been commercially used and used in the solar cell panels that can withstand the impact of the solar cells in a certain structure by connecting in series and parallel with the required unit capacity.

However, solar cells have the disadvantage that they cannot generate electricity on rainy, snowy or cloudless days, ie when sunlight is not emitted.

That is, since the solar cell generates electricity using sunlight, the more light is incident, the more electricity can be produced.

In particular, the solar generator 110 of the embodiment of the present invention, a motor (not shown) is installed on the rear of the light collecting plate 120 so that the light collecting angle of the light collecting plate 120 is changed according to the position of the sun, the memory 151 to be described later ) The position of the sun, that is, the circumference of the sun for each time zone, and the controller 150 changes the angle of the light collecting plate 120 according to the set time, or installs a light sensor (not shown). In accordance with the most preferred is applied to the solar position tracking photovoltaic generator configured to change the condensing angle of the light collecting plate 120, but is not limited thereto.

In addition, a specific configuration for changing the condensing angle according to the sun position is already known, so the detailed description thereof will be omitted herein.

Subsequently, the solar generator 110 includes a light collecting plate 120 and a water injection unit 121.

The light collecting plate 120 is provided with a plurality of solar cells arranged in series or in parallel to absorb the sunlight collected and generate electricity, and is configured to produce electric power generated through the solar cells.

The solar cell, as is well known, is composed of a semiconductor PN junction made of a semiconductor compound to enable direct conversion of solar energy into electricity.

That is, when solar light is irradiated to the solar cell, electromotive force is generated by the photovoltaic effect, and current is supplied to a load connected to the light collecting plate 120.

The water spraying unit 121 is provided so that the left and right sides correspond to the circumference of the light collecting plate 120, and the plurality of spray nozzles 122 spraying water to the front surface of the light collecting plate 120 on the left and right sides based on the light collecting plate 120. This is preferably formed, but is not limited to this, a plurality of spray nozzles 122 may be formed to face the front, rear.

The spray nozzle 122 is preferably formed so as to eject a high pressure liquid or gas, it is preferable that the nozzle is formed with a plurality of through-holes so that a large amount can be injected in a wide range even in a small amount.

In addition, the spray nozzle 122 may also be installed in a sprinkler type.

A flexi ball hose (not shown) is connected to the water supply pipe 191 at one side of the water jet part 121 provided around the light collecting plate 120.

That is, when a flexi ball hose (not shown) is provided between the water injection unit 121 and the water supply pipe 191, a motor (not shown) installed at one side of the light collecting plate 120 is driven to collect light according to the sun position. When the angle is changed, the light collecting plate 120 can operate smoothly.

The sensor unit 140 includes an outdoor temperature sensor 141, a light collecting plate temperature sensor 142, an air pollution sensor 143, a water temperature sensor 144, a wind direction and wind speed sensor 145, and a water pressure. Control sensor 146.

The outside temperature sensor 141 detects the temperature of the atmosphere around the light collecting plate 120, and detects the temperature of the atmosphere around the light collecting plate 120 to transmit the detected signal to the controller 150. It is preferable that it is a sensor.

In addition, the outside temperature sensor 141 may be installed on the light collecting plate 120, or may be separately installed around the light collecting plate and connected to the control unit 150. However, although not illustrated, it is most preferable to be installed on the light collecting plate 120. .

The light collecting plate temperature sensor 142 is a contact type temperature sensor that detects a temperature of the surface of the light collecting plate 120, and transmits the detected signal to the controller 150.

For example, it may be a (platinum) resistance temperature sensor, thermistor, thermocouple and bimetal that measures temperature through contact with a measurement object.

The outdoor air pollution sensor 143 is a pollution sensor that detects a pollution state of the air around the light collecting plate 120, and transmits the detected signal to the controller 150.

Similarly, the outside air pollution sensor 143 may be installed on the light collecting plate 120, or may be separately installed around the light collecting plate and connected to the control unit 150. Although not shown, it is most preferably installed on the light collecting plate 120. .

The water temperature sensor 144 is installed in the water supply pipe 191, detects the temperature of the water, and transmits the detected signal to the controller 150.

The wind speed sensor 145 and the wind direction sensor 146 are sensors for detecting the wind speed and the wind direction around the light collecting plate 120, and transmit the detected signal to the controller 150.

Similarly, the wind speed sensor 145 and the wind direction detection sensor 146 may be installed on the light collecting plate 120, or may be separately installed around the light collecting plate and connected to the control unit 150, but not illustrated in the light collecting plate 120. Most preferably, it is installed.

The controller 150 receives the detected signal from the outside air temperature sensor 141 and the light collecting plate temperature sensor 142, so that the surface temperature of the light collecting plate 120 is higher than the set reference temperature compared to the ambient air temperature. When the water supply signal is transmitted to the operation unit 160.

That is, when the reference temperature value is stored in the memory 151 and the surface temperature of the light collecting plate 120 rises above the set cooling set temperature value compared to the ambient air temperature, the controller 150 outputs a water supply signal to the operation unit 160. To send).

For example, when the ambient temperature sensed by the outside temperature sensor 141 is 20 degrees Celsius and the reference temperature set in the memory 151 is 10 degrees Celsius, the light collecting plate 120 sensed by the light collecting plate temperature sensor 142 may be used. If the surface temperature is 30 degrees Celsius, the controller 150 transmits a water supply signal to the operation unit 160.

However, if the surface temperature of the light collecting plate 120 is less than 30 degrees Celsius, the controller 150 does not transmit a water supply signal to the operation unit 160.

In addition, when the surface temperature of the light collecting plate 120 detected by the light collecting plate temperature sensor 142 is 10 degrees Celsius, and the coolant set temperature value set in the memory 151 is 5 degrees Celsius, the water temperature detecting sensor 144 detects the water. If the temperature of the water is 15 degrees Celsius or more, the controller 150 does not transmit a water supply signal to the operation unit 160.

That is, if the water temperature is higher than the surface temperature of the light collecting plate 120, the cooling effect is not obtained.

In addition, as will be described later, the coolant setting temperature value and the cooling setting temperature value stored in the memory 151 may be stored for each unit by each season, each month, and each week.

Subsequently, the controller 150 receives a signal detected from the outside air pollution sensor 143 and transmits a water supply signal to the operation unit 160 when the pollution state around the light collecting plate 120 rises above a reference value.

Also, as will be described later, the air pollution reference value is stored in the memory 151, and the stored air pollution reference value may be stored for each unit in each season, each month, and the like.

In addition, the controller 150 receives a signal detected from the outside temperature sensor 141, when the water in the water supply pipe 191 is lowered to 0 degrees Celsius or less, the water drainage signal to the operation unit 160 Send.

In addition, the controller 150 receives the wind speed and wind direction signals detected from the wind speed sensor 1455 and the wind direction sensor 146.

At this time, the controller 150 receives the wind speed detection signal and transmits a water supply cutoff signal to the operation unit 160 when the wind around the light collecting plate 120 rises above the set wind speed.

When the water is sprayed onto the light collecting plate 120, the controller 150 transmits a water supply cutoff signal to the operation unit 160 even when the wind direction of the blowing wind is the reverse direction of the water spraying direction.

That is, the light collecting angle of the light collecting plate 120 is changed according to the circumference of the sun, and the controller 150 is configured to spray the water with the wind direction detected by the wind direction detecting sensor 146 according to the current light collecting angle of the light collecting plate 120. It is to calculate whether or not the reverse direction, and in the reverse direction to transmit the water supply cutoff signal to the operation unit 160.

The same is true when the light collecting angle of the light collecting plate 120 is changed according to the light collecting angle set in the memory 151.

In addition, the controller 150 adjusts the pressure of the automatic pressure adjustment tank 162 to be described later.

The controller 150 also includes a memory 151.

The memory 151 stores a reference value for comparing whether the outside air temperature detected by the outside air temperature sensor 141 is high or low compared to the surface temperature of the light collecting plate 120 detected by the light collecting plate temperature sensor 142.

In addition, a coolant set temperature value is stored which compares whether the temperature of the water in the water supply pipe 191 detected by the water temperature sensor 144 is high or low compared to the ambient air temperature detected by the air temperature sensor 141.

The pollution reference value, the wind speed sensor 145, and the reference wind speed value of the outside air pollution detection sensor 143 are stored, and the opening times of the water supply valve 163 and the water drain valve 164 to be described later are stored.

Also, the reference value may be stored in the memory 151 for each unit such as each season, month, and week, and the reference value may be input or changed using the user computer 180.

In addition, the sensor unit 140 may be installed on one side of the solar generator 110, but may be installed around the solar generator 110, but most preferably, the sensor unit 140 is installed on the solar generator 110.

The controller 150 may be installed in the solar generator 110 or the operation unit 160, but is not limited thereto.

Meanwhile, the operation unit 160 includes a water supply pump 161, an automatic pressure control tank 162, a water supply valve 163, and a water drain valve 164.

The water supply pump 161 is connected to the water storage tank 170, and when the water supply signal is received from the controller 150, pumps the water stored in the water storage tank 170.

In addition, water is stored in the water storage tank 170, and the water is preferably cold water, but low temperature gas may be stored in addition to water, but is not limited thereto.

Subsequently, the automatic pressure adjusting tank 162 adjusts the intensity of the flow pressure of the water supplied to the water supply pipe 191 by pumping the water supply pump 161.

Then, the flow pressure of the water adjusted from the automatic pressure control tank 162 is adjusted from the control unit 150.

The water supply valve 163 opens the valve when the water supply signal is transmitted from the control unit 150.

When the water supply valve 163 is open, the water flowing into the water supply pipe 191 is controlled by the pressure pumped by the water supply pump 161 and the pressure adjusted from the automatic pressure control tank 162. Is supplied.

In addition, when the water supply shutoff signal is transmitted from the controller 150 to the operation unit 160, the water supply valve 163 closes the valve to prevent the water from flowing into the water supply pipe 191.

That is, as described above, when water is sprayed on the surface of the light collecting plate 120 when the surface temperature of the light collecting plate 120 rises above the set coolant setting temperature value compared to the outside temperature, the wind speed around the light collecting plate 120 is set. If the above rises, the controller 150 transmits a water supply cutoff signal to the operation unit 160, and when the water supply cutoff signal is transmitted to the operation unit 160, the water drain valve 164 closes the valve so that the water is closed. It does not flow into the water supply pipe (191).

In addition, when the water drain signal is transmitted from the controller 150, the water drain valve 164 opens the valve to discharge water in the water supply pipe to the drain pipe 192 connected to the water supply pipe 191.

That is, the outside air temperature measured by the outside air temperature sensor 141 is lowered to 0 degrees Celsius or less, and the water in the water supply pipe 191 is discharged before the water in the water supply pipe 191 is frozen and the water supply pipe is frozen. In winter, the water supply pipe 191 can prevent freezing.

Subsequently, the user terminal 180 is most preferably a personal computer (PC) capable of transmitting a water supply signal, a water supply cutoff signal, and a water drainage signal to the controller 150 through wireless or wired communication. It may also be a mobile phone, but is not limited thereto.

In addition, the user detects the above-described cooling set temperature value, the coolant set temperature value, the pollution reference value of the outside air pollution sensor 143, and the wind speed by using the user terminal 180 in the memory 151 of the controller 150. The reference wind speed value of the sensor 145 and the reference wind speed value of the wind direction detection sensor 146 may be stored, and opening times of the water supply valve 163 and the water drain valve 164 may be stored.

Accordingly, the user may remotely operate the operation unit 160 by transmitting a water supply signal, a water supply cutoff signal, and a water drainage signal using the user terminal 180 at a remote location.

That is, since the user can manually operate the control unit 150 from a remote location, even when a wildfire or other fire, which is a natural disaster, may occur, remotely spraying water even in a distant area may protect the solar generator 110. .

2 is an overall configuration diagram of a solar generator washing and cooling system according to another embodiment of the present invention.

With reference to Figure 2 will be described in detail another embodiment of a solar generator washing and cooling system according to the present invention.

First, another embodiment of the present invention is preferably applied to a stationary solar generator.

The water supply pipe 191 is connected to one side of the first support 210 and the second support 220, and is preferably connected to the water supply pipe 191 connected to the water storage tank 170.

The spray nozzle 122 is most preferably installed on one side of the water supply pipe 191 so as to face the light collecting plate 120, but may be installed on both sides so as to face the rear surface of the light collecting plate 120.

In addition, the spray nozzle 122 is preferably formed in a form that can spray the water supplied to the water supply pipe 191, and also in the form of a sprinkler to rotate the spray nozzle 122 left, right or 360 degrees You can also install it.

On the other hand, since the sensor unit 140, the controller 150, the operation unit 160, the water storage tank 170 and the user terminal 180 has already been described in an embodiment of the present invention, a more detailed description here Will be omitted.

That is, the solar generator cleaning and cooling system according to another embodiment of the present invention is applied to a stationary solar generator.

3 is an operational flowchart of a cooling system for cooling the light collecting plate in the solar generator cleaning and cooling system of FIGS. 1 and 2.

Referring to FIG. 3, one embodiment of the present invention is applied to the following method as well as another embodiment.

First, the controller 150 compares whether the outside air temperature detected by the outside air temperature sensor 141 is lower than a temperature at which the water in the water supply pipe 191 freezes (for example, 0 degrees Celsius) (step S201).

At this time, if the outside temperature is lower than the temperature (zero degrees Celsius) to freeze the water in the water supply pipe 191, the controller 150 transmits a water drain signal to the water drain valve 164.

Then, the valve of the water drain valve 164 is opened, and the water in the water supply pipe 191 is discharged to the outside through the drain pipe 192 (step S202).

After the step S201, if the outside air temperature is higher than the temperature (0 degrees Celsius) to freeze the water in the water supply pipe 191, the water temperature detected from the water temperature sensor 144 is detected from the light collecting plate temperature sensor 142 In step S203, the controller 150 compares whether the water temperature is higher or lower than the cooling water set temperature value set in the memory 151 (step S204).

At this time, when the water temperature is higher than the surface temperature of the light collecting plate 120 than the set coolant set temperature value, compared to the surface temperature of the light collecting plate 120 detected by the light collecting plate temperature sensor 142 from the outside air temperature sensor 141 The controller 150 compares whether the detected outside temperature (step S205) is higher or lower than the cooling set temperature value set in the memory 151 (step S206).

Next, when the surface temperature of the light collecting plate 120 is higher than the cooling set temperature value set in the memory 151 compared to the outside temperature, the wind blowing around the light collecting plate 120 detected by the wind speed sensor 145 (step S207). The controller 150 compares whether the air temperature rises above the wind speed set in the memory 151 (step S208).

At this time, when the wind blowing around the light collecting plate 120 is more than the wind speed set in the memory 151, the wind direction around the light collecting plate 120 detected by the wind direction detecting sensor 147 (step S209) of the water to be sprayed to the light collecting plate 120. When not in the reverse direction, if the outside air temperature is higher than the reference temperature value set in the memory 151 compared to the surface temperature of the light collecting plate 120 (step S210), the controller 150 outputs a water supply signal to the operation unit 160. The water supply pump 161, the automatic pressure control tank 162 and the water supply valve 163 transmits a water supply signal.

Then, when a water supply signal is transmitted to the water supply pump 161, the automatic pressure regulating tank 162, and the water supply valve 163, the water supply pump 161 receives the water stored in the water storage tank 170. When the pump is pressurized to the automatic pressure control tank 162 and the water supply valve 163 opens the valve, the pumped water is introduced into the water supply pipe 191.

Thus, the water flowing into the water supply pipe 191 is supplied to the water injection unit 121 by the pressure pumped from the water supply pump 161 and the pressure of the automatic pressure control tank 162, to the light collecting plate 120 It is injected (step S211).

Then, when the opening time of the water supply valve 163 set in the memory 151 is reached, for example, when the set opening time is about 3 to 10 minutes, when the opening time is reached, the controller 150 The water cutoff signal is transmitted to the operation unit 160 (step S212), and the water cutoff signal is sent to the water supply pump 161, the automatic pressure control tank 162, and the water supply valve 163 of the operation unit 160. When transmitted, the water supply pump 161 and the automatic pressure regulating tank 162 stop operation, and the water supply valve 163 closes the valve (step S213).

Subsequently, the controller 150 compares whether the pollution state of the surrounding external air of the light collecting plate 120 detected by the air pollution detection sensor 143 is greater than or equal to the pollution reference value set in the memory 151.

At this time, when the external air pollution state is higher than the pollution reference value set in the memory 151, the water supply signal to the water supply pump 161, the automatic pressure control tank 162 and the water supply valve 163 of the operation unit 160. If it is transmitted (step S215) and the external air pollution state is equal to or less than the pollution reference value set in the memory 151, the process returns to the step S201.
