In the cross-sectional view of the control panel of Figure 2b is a cross-sectional view taken from the bottom to the top. The upper part of the control panel is to install a forced exhaust fan 106 and forcibly discharge the heated air inside, and the filter 200 is installed in the lower part of the roof to allow the air to be discharged smoothly.

The forced exhaust fan 106 also has the effect of dissipating the photovoltaic panel 101 because it is located below the photovoltaic panel 101. When snow is accumulated on the roof of the control panel in winter, the air warmed by the equipment inside the control panel is discharged by the forced exhaust fan 106 and this heat can be used to melt the snow of the solar panel 101 and the roof.

As shown in FIG. 3, the control panel is manufactured by filling a heat insulating material 301 between the outer wall steel plate 302 and the inner wall steel sheet 300 in the double insulation wall detailed view.

As the heat insulator 301, it is preferable to use a silver foil-coated heat insulator capable of reflecting radiant heat transmitted through the outer wall steel plate 302. This can block the radiant heat in the summer to suppress the temperature rise of the internal control panel, and conversely, in winter, the control panel can be insulated from cold outside air.

Figure 4a is shown to explain the ventilation structure of the outdoor control panel of the pump station according to the present invention, Figure 4b shows the base structure for air-cooled heat exchange of the outdoor control panel of the pump station according to the present invention, Figure 4c 4 shows a detailed view of the baffle plate shown in FIG.

As shown in Figure 4a to 4c, in the lower underground structure of the concrete foundation 400, the control panel is installed in the ventilation structure by the water (sewage, waste water, etc.) to be introduced in the summer using air-cooling excellent cooling effect in the summer Heat exchange is performed with the base 104 for heat exchange.

The air flowing into the lower air filter 401 is cooled while passing through the air-cooled heat exchange base 104 half a turn and is supplied into the control panel through the control panel internal filter 201. The control panel internal filter 201 uses a ventilation opening of a structure that can be opened and closed to close in winter to block the inflow of cold air.

The air-cooled heat exchange base 104 may further increase the cooling effect when installed in the form of being buried as much as possible in the concrete foundation 400.

The air supplied into the control panel is discharged through the forced exhaust fan 106 through the filter 200 at the bottom of the roof and the vent 402 at the top of the roof. Ventilation openings 402 in the upper part of the roof are installed on both sides to serve to discharge the internal air discharged from the forced exhaust fan 106 and the heat generated from the solar panel 101 to the outside.

Here, in the duct structure of the air-cooled heat exchange base 104, a baffle plate 501 may be installed to heat exchange with hot air introduced from the outside in order to increase the effect of air cooling, and preferably, hot air Can be installed on both sides facing the inlet to the inlet.

The baffle plate 501 serves to control the flow of airflow, the inside is empty, and the inside shape of the baffle plate 501 has a form in which the letter 'L' is continuously connected, as shown in FIG. The hot air introduced from the outside passes through the inside of the relatively cold baffle plate 501 through the inlet 502 of the baffle plate 501, and the air cooled by heat exchange with the outside hot air and the baffle plate 501 is baffle plate ( 501) exit through exit 503. The cooled air is then introduced into the outdoor control panel through the internal filter 201.

The double base 504 of the duct structure can be widely contacted with the ground surface 603d separately from the air-cooled heat exchange base 104. It is a structure that can be installed buried in the ground to collect cold air on the surface 603d more effectively.

The portion having the heat exchanger may be installed so that the cold air 603c can circulate through the baffle plate 104 into the discharge hole 602a. The remaining principle is the same as the description of the drawing shown in FIG.

Figure 8 shows the internal circuit diagram of the outdoor control panel of the pump station according to the present invention.

As shown in FIG. 8, the control panel includes a solar cell 802, a commercial power source 801, a charging device 803, a storage battery 805, and a remote terminal unit (RTU) 806. . The charging device 803 charges the storage battery 805 by the charge controller 804 through the voltage sensing device 803a and the switching device 808 using the photovoltaic cell 802 as a main power source, and the remote terminal device 806 and the modem. Configured for use as a water level and flowmeter power.

It is determined by the remote terminal device 807 through the voltage sensor 803a and the illuminance sensor 807 that the solar cell is abnormal, and the transfer command to receive power through the commercial power 801 through the switch 808. Down. The part 801 that receives the AC for commercial use and changes the DC 24V may be combined with or separate from the charging device, so it is referred to as a commercial power supply 801 from the device (SMPS DC POWER DC 24V) converted from AC to DC.

The time point of switching from the commercial power supply 801 to the photovoltaic cell 802 is changed when the main power photovoltaic cell outputs a normal output. The storage battery 805 can be used for the back-up when the main power supply 802 and the auxiliary power supply 801 are abnormal to realize an uninterrupted operation of the remote terminal device 806. The remote terminal device 806 determines whether there is an abnormality of the photovoltaic cell 802 as the main power source and the commercial power source 801 as the auxiliary power source through the voltage sensing 803a and 803b, and the efficiency of the photovoltaic cell through the illuminance sensor 807. Is sent to the remote monitoring PC. The charging controller 804 transmits the state of charge of the battery 805 to the remote terminal device 806, and the remote terminal device transmits to the remote monitoring PC through the transmission device.

Compared with the existing uninterruptible power supply of the charging device, the simplest structure and dual power supply are the biggest features. There is no need for a device that converts DC to AC by using a remote terminal device whose power supply is DC. The remote terminal can know the state of the main power supply, the preliminary power supply, and the battery in advance, so there is an advantage of non-stop operation through preventive maintenance.
