Recently, an old-fashioned sea patrol boat that has been idle for a long time due to the inability to open air conditioners using DC batteries has been reborn under the innovation of the Zhenjiang Maritime Safety Administration.
"Sea patrol 0824 boat" is a 15M FRP modified boat. Because there is no AC power supply system, air conditioning cannot be used during navigation. In summer, the cab temperature is above 40 °C, and personnel cannot work. In winter, low temperature water waves hit the cab, and the glass is easy to freeze. It gives hope to cause difficulties and affects safe navigation.
In order to let the air conditioner open and revitalize the old boat, the maintenance personnel of Zhenjiang Maritime Safety Bureau actively used their brains to find ways to consult with local manufacturers and carefully research and design. Finally, they successfully developed DC inverter booster power supply. The device makes the DC battery installed on the boat after being supercharged by the inverter, and becomes an AC voltage. The primary battery can be used for 1.5 hours of continuous operation for 6 hours. The long-lost "Sea patrol 0824" has been re-arriving on the Yangtze River. The success of this technology saves the tens of thousands of generators for the unit, and the technology can also be used in special environments and emergency power supply for computers.
