Preferably, the battery box hanging ladder C3 is optionally but not limited to be connected to the floating island body in a rotating way, and can be connected with an electrically driven ship to form a transportation channel when put down, and can form a portal structure of the guardrail C4 when retracted, so that the safety of the floating island is improved.

Further, the power conversion floating island C further comprises a ship hook C5 used for being connected with the electrically driven ship.

In this embodiment, the ship hook C5 is located on the side of the power conversion floating island C close to the side where the electrically driven ship is berthed; the ship hook C5 is directly connected with the electric driving ship, so that relative standing between the electric driving ship and the power changing floating island C is further stabilized, and accidents of the battery in the replacement process are prevented.

Preferably, the ship hook C5 is connected with the power conversion floating island C in a rotating way.

(IV) Battery box D

Further, in order to facilitate the quick replacement of batteries for electrically driven vessels by the power-driven floating island C, the invention also provides a battery box D, as shown in FIG. 8, comprising a box base D1 for bearing the batteries, a cover plate D2 movably connected to the box base D1, and a rotating rod D11 capable of rotating around itself relative to the box base D1.

In the embodiment, a battery box of the invention is provided, on one hand, a box body structure with a certain protection effect is formed by a box body base and a cover plate, and the battery box is arranged on an electric driving ship; on the other hand, add the dwang that can rotate around self for the box base for the battery can be under the effect of dwang, light quick input or output battery box improves battery replacement efficiency, reduces intensity of labour.

Specifically, when the battery needs to be input into the battery box D, the cover plate D2 is firstly moved away from the upper side of the battery box underframe 1, the upper side of the box base D1 is guaranteed to be in an open state, then the battery is placed on the rotating rod D11 positioned at the edge of the battery box D, then the battery is pushed inwards, the rotating rod D11 rotates around the battery in the pushing process, the battery is moved to the depth of the box base D1, and then the cover plate D2 is placed above the box base D1 again. And otherwise, outputting the battery to the battery box.

Preferably, the cover plate D2 is rotatably connected to the box base D1. Specifically, a cover plug is arranged at a position on the cover plate D2, which is in contact with the box base D1, and a cover socket is arranged at a position on the box base D1, which is in contact with the cover plate D2, and the cover plug and the cover socket are matched, so that the cover plate D2 rotates around a common shaft.

Further, the cover plate D2 is provided with a backrest D21 on a side away from the rotation center thereof.

In this embodiment, the cover D2 and the backrest D21 constitute a seat for passengers, that is, the battery box is used as a seat, and does not occupy other space of the electrically driven ship to improve the passenger carrying capacity.

Further, two sides of the outer wall of the box base D1 are provided with connecting hanging columns D3.

In this embodiment, when the electrically driven vessel is stopped near the power changing floating island C, it is convenient to cooperate with the power changing floating island, and the battery box D and the electrically driven vessel are fixed by using the connection hanging column D3, so as to ensure that the electrically driven vessel and the power changing floating island C are relatively stationary when the battery is replaced, and reduce the risk when the battery is replaced.

The invention has the advantages that:

the invention is provided with a charging station A, a transfer mechanism B and a power conversion floating island C; a charging cabinet A1 is provided in the charging station A, and is used for facilitating the putting in and taking out of the battery; the tray is provided in the transfer mechanism B and is used for improving the battery transfer efficiency and reducing the labor intensity; the specific structure of the power-changing floating island is provided in the power-changing floating island C, and is used for realizing the quick battery replacement of the electrically-driven ship; the battery box is used for facilitating input and output of the battery; the novel charging and replacing mode is integrally provided.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
