AI Technical Summary

Technical Problem

The existing battery replacement method for electric ships requires docking at a designated wharf or shore-side battery replacement station, and has requirements for the docking direction of the ship, which makes battery replacement difficult and the experience poor, especially for large ships, where turning operations are difficult.

Method used

A floating battery swapping system was designed, in which the station itself is fixed to the riverbed, with a support platform elevated above the river surface. The battery swapping mechanism is mounted on the platform, allowing ships to swap batteries from either side of the platform. The system includes tracks, a movable arm, and a battery gripper, capable of traveling, rotating, and lifting, enabling battery swapping operations in any direction and position.

Benefits of technology

It enables the ship to complete battery replacement during normal sailing, avoiding the operation of sailing to the shore or turning the bow, and improving the battery replacement efficiency and user experience.

Abstract

The present invention provides an on-water battery exchange system, comprising: a battery exchange station body, a battery exchange mechanism and a ship. The battery exchange station body is fixed to the riverbed, and the battery exchange station body has a support platform, which is higher than the river surface. The battery exchange station body and the river banks on both sides have space for ships to pass through, and battery boxes are stored on the support platform. The battery exchange mechanism is arranged on the support platform. The ship has a mounting seat for installing the battery box, and the ship can travel to either side of the support platform to cooperate with the battery exchange mechanism to perform the battery exchange operation. The battery exchange station body of the on-water battery exchange system of the present application is arranged in the center of the water area, and no longer occupies the dock or other venues, thereby increasing space utilization, and the ship can perform battery exchange during normal driving, avoiding operations such as driving to the shore or turning the bow, saving time. The battery exchange mechanism of the on-water battery exchange system has the functions of walking, rotating and lifting, so the ship can complete the battery exchange task in any direction and position of the support platform, thereby improving the battery exchange efficiency.
