[0057] The marine charging device provided in this embodiment includes a charging interface and a charging plug connected to a power supply. When charging, the charging interface can be matched and connected to the charging plug for charging. In order to facilitate ship charging, improve the efficiency and safety of ship charging, reduce labor intensity, and reduce labor costs, such as Figure 1 to Figure 3 As shown, the charging interface includes an automatic charging interface 101, and the charging plug includes an automatic charging plug 204 that matches the automatic charging interface 101. The automatic charging plug 204 is used to automatically insert or pull out the automatic charging interface 101, thereby realizing automatic charging.

[0058] In order to realize the above-mentioned automatic charging, the marine charging device also includes a docking bin 10 , a charging room 20 , a positioning mechanism (not shown) and a clamping mechanism 205 .

[0059] The docking bin 10 is set on the ship, and the automatic charging interface 101 is set in the docking bin 10 . When the ship needs to be charged, the ship docks so that the docking chamber 10 faces the shore, so as to facilitate docking with the equipment on the shore.

[0060] The automatic charging plug 204 , the positioning mechanism and the clamping mechanism 205 are all arranged in the charging room 20 . Wherein, the positioning mechanism is configured to determine the position of the automatic charging interface 101 . The clamping mechanism 205 is used for clamping the automatic charging plug 204 .

[0061] In this embodiment, when the ship needs to be charged, after the corresponding charging room 20 docks, the positioning mechanism can determine the position of the automatic charging interface 101 in the docking compartment 10. According to the position information determined by the positioning mechanism, the clamping mechanism 205 will automatically charge the charging plug. 204 corresponds to the insertion of the automatic charging interface 101 . After the charging is completed, the clamping mechanism 205 clamps the automatic charging plug 204 to move out of the automatic charging interface 101, and moves into the charging room 20, thereby realizing the automatic charging of the ship, reducing the time for docking the charging plug and the charging interface, and improving the charging efficiency. Efficiency, reliability and safety, reduced labor intensity, and saved labor costs.

[0062] Due to the high frequency of ship charging and the use environment is outdoors, it is easily affected by external factors such as weather, which may cause failures during use. When the automatic charging fails, in order to enable the ship to charge normally, such as figure 2 , image 3 As shown, the charging interface further includes a manual charging interface 102 disposed below the automatic charging interface 101 , and the manual charging interface 102 is disposed below, which is convenient for personnel to operate. The charging plug (not shown) also includes a manual charging plug matched with the manual charging interface 102 , and the manual charging plug is arranged in the charging room 20 . Specifically, an industrial booster arm 207 is provided in the charging room 20 , and a manual charging plug is set on the industrial booster arm 207 , and the manual charging plug is inserted into the manual charging interface 102 with the assistance of the industrial booster arm 207 .

[0063] Therefore, the marine charging device of the present invention has two charging methods, automatic charging and manual charging, which can meet different charging needs and have a wide range of applications.

[0064] In order to facilitate the understanding of the implementation form of automatic charging, the part of automatic charging will be introduced in detail below.

Both sides of the main body 2053 are provided with a movable plate 2052 inside the fixed plate 2051 . A fixing groove 2054 capable of clamping and releasing the second roller 2043 is formed between the movable plate 2052 and the fixed plate 2051 on the same side.

[0067] Specifically, one side of the fixed plate 2051 is provided with a U-shaped groove, and the middle of the bottom of the U-shaped groove is recessed to form a semi-arc groove. The movable plate 2052 is provided with a lug 20521 corresponding to the opening of the half-arc groove. The arc-shaped groove cooperates to form a fixing groove 2054 .

[0068] The movable plate 2052 and the fixed plate 2051 are connected by a connecting rod assembly, and the movable plate 2052 is driven to swing relative to the fixed plate 2051 by the connecting rod assembly, so as to change the size of the opening of the fixed slot 2054 .

[0069] In order to facilitate the clamping mechanism 205 to clamp the automatic charging plug 204, as Figure 5 , Image 6 As shown, a second roller 2043 is respectively provided on both sides of the automatic charging plug 204 . When it is necessary to insert the automatic charging plug 204 into the automatic charging interface 101, the clamping mechanism 205 clamps the automatic charging plug 204, specifically, the clamping mechanism 205 opens the fixing groove 2054, so that the second roller 2043 is snapped into the fixing groove 2054 to realize Clamping; when the automatic charging plug 204 reaches the specified position, such as after being inserted into the automatic charging interface 101, and returns to the initial position, the fixing groove 2054 is opened, and the second roller 2043 is released to realize separation.

[0070] Further, a sensor 20511 is provided on the fixing plate 2051 corresponding to the fixing groove 2054 , and the sensor 20511 is configured to detect whether the second roller 2043 is clamped in the fixing groove 2054 . When the automatic charging plug 204 needs to be removed from the automatic charging interface 101 , the sensor 20511 can determine whether the clamping mechanism 205 clamps the automatic charging plug 204 in place.

[0071] In order to enable the clamping mechanism 205 to better cooperate with the positioning mechanism to insert the automatic charging plug 204 into the automatic charging interface 101, as Figure 1 to Figure 3 As shown, the marine charging device also includes an industrial robot 206 , and the industrial robot 206 is set in the charging room 20 .

After the 204 is moved out, the industrial robot 206 drives the clamping mechanism 205 to return to the initial position, so that the clamping mechanism 205 can accurately position the automatic charging plug 204 when it is pulled out or recharged. Specifically, the return mechanism 203 includes a reference base provided in the charging room 20 , and the clamping mechanism 205 can return to the initial position through the positional relationship information between the initial position of the clamping mechanism 205 and the reference base.
