[0001] The present invention relates to the technical field of ship shore power connection devices, and specifically relates to a ship high-efficiency shore power connection device. Background Technique

[0002] The shore power access system is an important part of the ship power system. During the process of the ship docking at the wharf for loading and unloading goods, equipment maintenance, and shipbuilding, in order to save resources, shore power is generally used to supply power to meet the basic power requirements for ship lighting and daily life.

[0003] Currently, when supplying shore power, it is necessary to manually wire inside the shore power device to complete. Generally, the shore power cable has a relatively thick specification, and the space inside the shore power device is limited. The incoming line and wiring are quite troublesome. Moreover, frequent disconnection and connection of the cable will damage the shore power cable, reduce the insulation, and it is necessary to check whether the terminal is tightened, and the terminal is often damaged, which has a relatively large potential safety hazard. In addition, when the ship approaches or leaves the shore (or wharf), the above disconnection and connection work processes need to be repeated, which requires high technical skills for the crew and increases the labor intensity to a certain extent. Summary of the Invention

[0046] Secondly, when the ship needs to be charged, only need to use the moving assembly and the moving wheels 7 of this equipment to move this equipment to a suitable position, then start the lifting assembly and start the cylinder 10 to drive the connecting plate 11 to move downward. Finally, move the support assembly out of the shore power connection main body 2 along the guiding groove. Specifically, the downward-moving connecting plate 11 moves the symmetric connecting columns 13 and the support seats 9 to contact the ground respectively. At the same time, under the action of the redirecting wheel 22, start the braking assembly and the downward-moving connecting plate 11 pulls the braking steel rope 23 to drive the brake pads inside the brake disc 8 to tighten. Also, because the brake disc 8 and the moving wheel 7 are coaxially designed, the moving wheel 7 is fixed. Through the above mechanism, during the charging process, the shore power connection main body 2 operates more stably;

[0047] Finally, while braking and supporting, the sealing assembly is opened. Specifically, the downwardly moving connecting plate 11 drives the connecting rod 12 and the rack 14 to move. Since the gear shaft 15 meshes with the rack 14, the gear shaft 15 is slowly rotated.

[0048] After charging is completed, after separating the corresponding connection plug 5 from the connection socket 4, the lifting assembly is started to restore it to its original state, the braking assembly is opened, the moving assembly is restored, the sealing assembly is closed, and the supporting assembly is retracted. Finally, the movement of the device is completed.
