[0049] Specifically, Figure 3 As shown, the linear drive assembly includes a fixed platform 11 fixed on the dock body 1 in a detachable manner, and the fixed platform 11 is simultaneously rotatably equipped with a screw rod 12 and fixedly equipped with a slide rail 14, the slide rail 14 is consistent with the extension direction of the screw rod 12, and is also consistent with the movement direction of the charging plug 7, the screw rod 12 is transmission-connected to a drive motor 13 arranged on the fixed platform 11, the mounting seat 4 is threadedly connected to the screw rod 12, the mounting seat 4 is slidably connected to the slide rail 14, and the drive motor 13 drives the screw rod 12 to rotate so that the mounting seat 4 moves on the slide rail 14. Two proximity switches 15 are provided on the fixed platform 11, and the two proximity switches 15 are respectively located at the two ends of the slide rail 14, and the two proximity switches 15 are used to limit the moving distance of the mounting seat 4. When the proximity switch 15 on the corresponding side senses that the mounting seat 4 is approaching, the proximity switch 15 will transmit a signal to the drive motor 13 to stop, so as to prevent the drive motor 13 from excessively moving the mounting seat 4.

[0050] In other embodiments, the fixing platform 11 cannot be removed from the dock body 1 .

[0051] In other embodiments, the linear drive assembly includes a fixed platform 11 fixed to the dock body 1 in a detachable manner, a cylinder or a hydraulic cylinder or an electric push rod is provided on the fixed platform 11, a slide rail 14 is also provided on the fixed platform 11, the mounting seat 4 slides on the slide rail 14, and the cylinder or the hydraulic cylinder or the electric push rod is connected to the mounting seat 4 to drive the mounting seat 4 to slide on the slide rail 14.

[0052] like Figure 2 , Figure 3As shown, a protective cover 9 is provided on the fixing platform 11, and the protective cover 9 covers the driving motor 13, the screw rod 12, the slide rail 14 and the proximity switch 15 to prevent the outside from damaging these components.

One end of the torsion spring 22 is fixed to the follower cover 18, and the other end of the torsion spring 22 is fixed to the front fixing seat. Because the front fixing seat is fixed, and the follower cover 18 rotates around the hinged position with the front fixing seat, the torsion spring 22 can reset the follower cover 18 after rotation. A maintenance component is provided between the front fixing seat and the rear fixing seat to keep the charging plug 7 in a posture that can be plugged into the charging socket when the follower cover 18 rotates. The rear fixing seat of the front movable arm 6 is fixedly connected to the front fixing seat of the rear movable arm 6, the front fixing seat of the frontmost movable arm 6 is fixedly connected to the mounting seat 4, and the rear fixing seat of the rearmost movable arm 6 is connected to the charging plug 7.

[0055] When the ship 2 arrives at the dock body 1 and needs to be charged, the drive motor 13 drives the screw rod 12 to rotate, and the screw rod 12 moves the mounting seat 4, thereby driving the charging plug 7 to move toward the charging seat 43. Because of the trumpet-shaped guide shell 31 and the two movable arms 6, even if the ship 2 is not docked at a precise position, the position of the charging plug 7 during operation will also change adaptively, that is, the charging plug 7 can be accurately connected to the charging seat 43 to realize charging of the ship 2; at the same time, by arranging the maintenance component, the charging plug 7 is always in a posture that can be plugged into the charging socket when the follow-up cover 18 rotates. At the same time, when charging is not needed, the swing arm 5 can be reset due to the action of the torsion spring 22.

[0056] Specifically, Figure 4-Figure 7As shown, the front side fixing seat includes two spaced front side fixing plates 16, on which the stator surrounding shaft 23 is rotatably mounted, the torsion spring 22 is sleeved on the stator surrounding shaft 23, one end of the torsion spring 22 is fixed on the follower cover 18, and the other end of the torsion spring 22 is fixed on one of the front side fixing plates 16. The follower cover 18 is located between the two front side fixing plates 16, and the follower cover 18 is rotatably mounted on the stator surrounding shaft 23. Specifically, the rear side fixing seat includes two spaced rear side fixing plates 17, on which the rotor surrounding shaft 24 is rotatably mounted, the follower cover 18 is located between the two rear side fixing plates 17, and the follower cover 18 is rotatably mounted on the rotor surrounding shaft 24. The charging plug 7 is arranged on the two rear side fixing plates 17. In this embodiment, the stator surrounding shaft 23 and the rotor surrounding shaft 24 are parallel to each other. In this embodiment, the stator surrounding axis 23 in the front movable arm 6 and the stator surrounding axis 23 in the rear movable arm 6 are perpendicular to each other. The maintenance assembly includes a stator sprocket 19 fixedly mounted on the front side fixing plate 16 and a rotor sprocket 47 fixedly mounted on the rear side fixing plate 17. The stator sprocket 19 and the rotor sprocket 47 are located on the same side and have the same specifications. The stator sprocket 19 and the rotor sprocket 47 are meshed with a chain 20 at the same time, so that the charging plug 7 is always in a posture that can be plugged into the charging socket when the follower cover 18 rotates.

[0057] Specifically, Figure 5-Figure 7 As shown, the movable arm 6 also includes a protective cover 25 located outside the stator sprocket 19 and the rotor sprocket 47, and the stator surrounding shaft 23 and the rotor surrounding shaft 24 are both rotatably assembled with the protective cover 25.

The protective cover 25 is rotatably assembled with a tensioning wheel 21 that meshes with the chain 20, and the tensioning wheel 21 is used to tension the chain 20. The tensioning wheel 21 can adjust the tightness of the chain 20, ensuring that the stator surrounding shaft 23 and the rotor surrounding shaft 24 can be more accurately synchronized.

[0058] A connecting plate 46 is detachably fixed between the protective cover 25 and the follower cover 18 . Four avoidance notches 26 are provided on the connecting plate 46 . The positions of the four avoidance notches 26 correspond to the positions of the two front fixing plates 16 and the two rear fixing plates 17 .

[0059] Specifically, Figure 8 , Fig. 9 , Fig.12 , Fig.13As shown, the charging socket includes a guide shell 31 arranged on the ship 2, the guide shell 31 is a trumpet-shaped one with a diameter gradually decreasing from the outside to the inside, the guide shell 31 has a trumpet-shaped accommodating cavity 32 with a diameter gradually decreasing from the outside to the inside, and the inner wall of the accommodating cavity 32 is provided with two sliding guide grooves 33 with a width gradually decreasing from the outside to the inside, and a guide seat 36 is provided in the accommodating cavity 32 at the ends of the two sliding guide grooves 33, and a charging seat 43 is provided on the guide seat 36.

[0060] like Figure 8-Figure 11 As shown, the charging plug 7 includes a shell 34, a guide ring 37 provided on the shell 34, and a charging head 41 provided on the shell 34. The shell 34 is connected to the two rear fixing plates 17 of the most terminal movable arm 6. The charging head 41 is located in the guide ring 37. The outer side of the shell 34 is provided with a guide column 35 for sliding in the corresponding sliding guide groove 33, so that the charging head 41 can be more accurately connected to the charging seat 43. The guide ring 37 is used to wrap the guide seat 36, so that the charging head 41 can be more accurately inserted into the charging seat 43. The cooperation between the guide column 35 and the sliding guide groove 33 can make the charging plug 7 easier and more accurately inserted into the charging seat 43 even if the docking position of the ship 2 is not accurate, thereby increasing the fault tolerance. In this embodiment, the sizes of the two guide columns 35 are different, and the sizes of the two sliding guide grooves 33 are also different. The guide column 35 and the sliding guide groove 33 are adapted, so that the charging head 41 can be more accurately inserted into the charging seat 43. In this embodiment, two guide posts 35 of different sizes are arranged relatively on the housing 34 , and the sliding guide grooves 33 are also arranged relatively in the accommodating cavity 32 .

[0061] like Figure 8 , Fig.10 , Fig.12As shown, the guide seat 36 is provided with a socket iron block 44, and the socket iron block 44 is provided with a protrusion 45 facing outward. The outer shell 34 is provided with an electromagnet 39 located in the guide ring 37 and corresponding to the socket iron block 44, and the electromagnet 39 is electrically connected to a limit switch 38 located inside the outer shell 34, and the limit switch 38 partially extends out of the outer shell 34 and the position corresponds to the protrusion 45. The limit switch 38 is electrically connected to the electromagnet 39 and the drive motor 13, and the limit switch 38 is used to control the operation of the electromagnet 39 and the drive motor 13, and the limit switch 38 is connected to a reset spring. When the limit switch 38 is triggered, the ship 2 starts to be charged, and the drive motor 13 will stop running at the same time, and the electromagnet 39 magnetically attracts the socket iron block 44. After charging is completed, the charging head 41 is separated from the charging seat 43, and the limit switch 38 is reset under the action of the reset spring. When the charging head 41 is connected to the charging seat 43, the limit switch 38 will be triggered by the protrusion 45 on the socket iron block 44, so that the electromagnet 39 can electromagnetically attract the socket iron block 44, thereby ensuring the stability of the connection between the charging head 41 and the charging seat 43. At the same time, when the limit switch 38 is triggered, the limit switch 38 will simultaneously turn off the drive motor 13 and stop it from running, thereby preventing the drive motor 13 from excessively driving the charging head 41 to move and damaging the charging head 41 (or the drive motor 13 stops after running for a set time).

[0062] The guide seat 36 is provided with a guide hole 42, and the housing 34 is provided with a guide rod 40 for inserting into the guide hole 42, and the guide rod 40 is located in the guide ring 37. When the charging head 41 is moved, the guide rod 40 is first inserted into the guide hole 42, so that the charging head 41 and the charging seat 43 can be connected more accurately.

[0063] The housing 34 is connected to a connector electrically connected to the charging head 41 , and the connector is connected to an external power source via a cable 8 .

[0064] like Figure 7 , Figure 8 As shown, a connection seat 27 is fixed on the rear fixing seat of the most distal movable arm 6, a sliding rod 28 for sliding on the connection seat 27 is fixed on the side of the housing 34 away from the guide ring 37, and a buffer spring 30 for pressing the connection seat 27 and the housing 34 is sleeved on the sliding rod 28. A buffer space is provided in the connection seat 27, one end of the sliding rod 28 extends into the buffer space, and a stopper 29 for preventing the sliding rod 28 from sliding out of the buffer space is provided on the end. The buffer space is provided in the connection seat 27, and when the ship 2 shakes, the charging plug 7 can slide on the connection seat 27, so that the charging equipment can be prevented from being damaged when the ship 2 shakes.

[0065] The working process of the present invention is as follows:

[0066] After the ship 2 reaches the charging position of the dock body 1, the charging module starts to operate. The drive motor 13 is started, the screw 12 rotates, and the mounting seat 4 slides on the slide rail 14 to move the charging head 41 toward the charging seat 43. When the docking position of the ship 2 is not suitable, the sliding of the guide column 35 in the sliding guide groove 33 will cause the follower covers 18 in the two movable arms 6 to rotate to adapt to the position of the charging seat 43.

[0067] After charging is completed, the driving motor 13 is reversed to reset the mounting base 4 , and the two movable arms 6 will return to their original postures under the action of the torsion springs 22 .
