In addition to power supply, the shore power box also has functions such as data acquisition, billing, and settlement, facilitating power management for both ports and vessels. The working principle of the shore power box is based on modern power transmission technology. First, the shore power box converts the AC power from the external power grid into DC power suitable for vessel use. Then, the power is transmitted to the connection device on the dock via cables. Under the action of the connection device, the power is delivered to the vessel's electrical system, providing the required power. This intelligent power transmission method not only achieves efficient power supply but also enables real-time monitoring of power quality and supply status, ensuring safety and reliability.

[0003] Currently, existing dockside power distribution boxes are typically equipped with supports to elevate them. However, traditional dockside power distribution boxes are usually fixed to the base support using bolts. This method of connection is time-consuming and requires tools during installation, thus reducing the ease of assembly. Furthermore, bolts exposed to the outside for extended periods are prone to corrosion, making disassembly very inconvenient. Utility Model Content

Furthermore, the stability is improved after the shore power box body 1 and the base frame 2 are assembled and connected. Then, the connecting seat 5 is placed from the bottom of the base frame 2 onto the two fixed plates 3. The connecting plate 3 is positioned between the two plates, and the top of the connecting seat 5 is made to fit against the main body 1 of the dock shore power box. Then, by rotating the adjusting knob 14 clockwise, the bidirectional lead screw 6 is driven to rotate by the meshing relationship between the first bevel tooth 13 and the second bevel tooth 15. At this time, the two threaded sleeves 7 connected to the outer wall will drive the connecting block 8 to move in opposite directions along the guide rod 9, and the limiting insert 10 connected to the outer wall of the connecting block 8 will extend outward and then be inserted into the first limiting groove 4 and the second limiting groove 12 in sequence. Thus, the assembly between the main body 1 of the dock shore power box and the base frame 2 can be realized more conveniently through the above method.
