The shore-based support of pure electric cargo ships mainly includes shore power systems, technical support, material supply, fault repair and other aspects. The shore power system refers to the use of shore power to provide electricity to ships docked at the port, replacing the ship's own fuel generator, thereby reducing the emission pollution of the ship while in the port.

A shore-based mobile charging pile for a pure electric cargo ship according to claim 6, Features: A driving motor (31) is installed inside the support base (1), the output end of the driving motor (31) is fixedly connected to the adjusting screw rod (30), the bottom of the adjusting slide plate (29) is symmetrically fixedly connected to a connecting support block (32), the bottom of the connecting support block (32) is fixedly connected to the adjusting box (34), and the connecting support block (32) is slidably connected to the support base (1).

8. A shore-based mobile charging pile for a pure electric cargo ship according to claim 7, Features: A second limiting slide bar (33) is symmetrically slidably connected inside the adjusting slide plate (29), and the second limiting slide bar (33) is fixedly connected to the supporting base (1).

9. A shore-based mobile charging pile for a pure electric cargo ship according to claim 8, Features: The outer side of the external thread pressing column (18) is threadedly connected with a limiting nut (19).

10. A method for using a shore-based mobile charging pile for a pure electric cargo ship according to any one of claims 1 to 9, It is characterized in that The following steps are involved: S1. Install and replace the detachable plug (10) and the charging plug (14) according to different types of pure electric cargo ships, rotate the limiting nut (19) upward, rotate the limiting nut (19) to the uppermost position of the external thread pressing column (18), insert the matching plug (13) on one side of the detachable plug (10) into the installation plug (7), and insert the detachable plug (10) into the inner sealing ring (12) on the inner side of the fixing tube (9), and seal the outer sealing ring (11) and the inner sealing ring (12) on the outer side of the detachable plug (10) to perform a sealed installation connection; S2, the mating plug (13) is inserted into the mounting plug (7), and when the sliding plate (16) and the inclined surface block (17) reach the position of the mounting groove (22), the mounting groove (22) pushes the inclined surface block (17), and the inclined surface block (17) is driven by the force to move the sliding plate (16), and the sliding plate (16) drives the external thread pressing column (18) to move to the position inside the fixed outer box (15), and the sliding plate (16) presses the reset spring (21), and when the inclined surface block (17) reaches the position below the bayonet (23), the reset spring is (21) will reset and drive the sliding plate (16) and the inclined clamping block (17) to reset, the inclined clamping block (17) enters the bayonet (23), the inclined clamping block (17) and the bayonet (23) are limited and fixed, and then the limiting nut (19) on the outside of the external thread pressing column (18) is rotated downward, and the bottom of the limiting nut (19) contacts the fixed outer box (15), and the pressing position of the external thread pressing column (18) is limited by the limiting nut (19), so that the stable installation and fixation between the inclined clamping block (17) and the bayonet (23) is completed; S3. When the position of the pure electric cargo ship charging pile body (4) needs to be moved, the universal wheels (2) below the support base (1) are moved. When the support base (1) moves, the position of the pure electric cargo ship charging pile body (4) is moved and adjusted. When the universal wheels (2) move, the universal wheels (2) drive the connecting support (38) and the inner sliding plate (35) to push the damper (36) and the shock-absorbing spring (37) upward, thereby reducing the vibration during movement; S4. While the pure electric cargo ship charging pile body (4) is moving and adjusting, the motor on one side of the winding box (24) is started, and the output end of the motor drives the winding roller (27) to rotate, and the outer connecting line (26) is released through the winding roller (27), so as to facilitate the movement of the support base (1) and the pure electric cargo ship charging pile body (4). After moving to a suitable charging position, the drive motor (31) is started through an external controller, and the output end of the drive motor (31) drives the adjustment screw rod (30) to rotate. When the adjustment screw rod (30) rotates, the outer adjustment slide plate (29) is moved upward, and the adjustment slide plate (29) moves upward and drives the bottom connection support block (32) to move upward. The connection support block (32) drives the adjustment box (34) to slide upward in the support base (1), thereby driving the connection support (38) and the universal wheel (2) to move upward, and the universal wheel (2) is stored in the opening (3) and supported by the support base (1).
