AI Technical Summary
In existing technologies, large mobile vehicles are not allowed to travel to the front edge of the dock, which prevents high-voltage electricity from being safely converted into low-voltage electricity to supply the equipment at the dock's front edge, thus presenting limitations.
A transformer-type mobile cable winch is used to convert high-voltage electricity to low-voltage electricity by laying cables in a pit below the dock. The high-voltage electricity is then connected to a low-voltage socket box via a low-voltage transfer box, enabling high-voltage to low-voltage conversion and flexible power supply.
It enables the safe conversion of high-voltage electricity to low-voltage electricity, meets the voltage requirements of equipment at the dock front, improves power supply efficiency and safety, and allows for flexible layout in different locations.
