Description

Technical Field

[0001] The utility model relates to the technical field of UPS uninterruptible power supply, in particular to a direct current UPS backup power device. Background Art

[0002] UPS stands for Uninterruptible Power Supply, which is an uninterruptible power supply with an energy storage device. It is mainly used to provide uninterruptible power supply to some equipment that requires high power stability. When the mains input is normal, the UPS stabilizes the mains and supplies it to the load. At this time, the UPS is an AC voltage stabilizer, and it also charges the battery inside the machine; when the mains power is interrupted (accidental power outage), the UPS immediately switches the DC power of the battery to the load through the inverter switching method to continue to supply 220V AC power to the load, so that the load maintains normal operation and protects the load software and hardware from damage. UPS equipment can usually provide protection against overvoltage or undervoltage.

[0003] Publication of patent specification for utility model patent in China CN213093934U The portable UPS uninterruptible power supply disclosed in the utility model is easy to move, simple in design and highly practical, but its practicality is poor. It needs to convert AC power into DC power through a rectifier / charger to charge the battery, and convert the DC power stored in the battery into AC power through an inverter to supply the equipment. In some special environments, the UPS backup power equipment cannot be charged by itself, which has the disadvantage of poor practicality. Utility Model Content

When in use, the main body of the backup power device is electrically connected to the power-consuming equipment, and at the same time detects the power supply of the main power supply. When the main power supply is normally supplied, the UPS will convert the power supply into DC power and charge the battery at the same time.

In addition to uninterrupted power supply, the backup power device can also be used by the staff to switch the backup power supply to the AC power supply after the power supply is exhausted. The electrical device is pushed to a place with sunlight, and at the same time, the output ends of the two servo motors are controlled by the controller to rotate forward, and the servo motor drives the screw rod to rotate, so that the moving block threadedly connected to the surface of the screw rod moves outward. During the movement, the moving block slides on the surface of the guide rod through the guide hole, which plays a role of limiting. Then, through the movement of the moving block, the moving frame is pushed outward from the through groove. At this time, the solar charging panel on the inside of the moving frame is exposed to sunlight, and the solar charging panel starts to work, converting solar energy into electrical energy through the solar charging panel, and the converted electrical energy is stored in the battery. The practicality of the device can meet the self-charging needs, and the mobile frame and the solar charging panel can be stored to reduce the space occupied, thereby achieving the purpose of improving the practicality of the device.
