[0002] In the field of electric vessel offshore charging technology, existing charging docking devices face numerous technical challenges due to the unique marine environment. Traditional devices generally suffer from the following technical deficiencies: 1. Sea waves cause the ship to move in six degrees of freedom (pitch, roll, heave, etc.). Existing devices mostly use straight tube or single cone surface guide structures, which lack the ability to dynamically correct deviations in three-dimensional space. 2. Alignment using manual or robotic arm assistance is inefficient and difficult to adapt to real-time changes in relative position; 3. Rigid docking mechanisms are prone to stress concentration under wave impact, leading to pin deformation and insulation layer damage; 4. The lack of a buffer mechanism causes mechanical fatigue during repeated insertion and removal, shortening the service life of the equipment.

[0014] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: for the electric boat marine charging docking device described above, the inner end of the guide hole 6 is a horn hole, and the guide head 29 is conical.

[0015] The technical problem to be solved by the present invention can also be further achieved through the following technical solution: For the electric ship marine charging docking device described above, an electric ship marine charging docking method comprises the following steps: (1) Preliminary positioning and guidance preparation When the electric boat sails to the charging area, the charging interface area of ​​the boat is brought close to the guide plate 3 on the side of the waterproof box 1, and the horizontal distance between the two is kept within a safe range. Check whether the guide plate 3 has been installed on the designated side of the waterproof box 1 via the detachable sliding structure, and confirm that the interface 4, plug connector 5 and guide hole 6 are not obstructed or damaged; (2) Initial alignment of the directional insertion mechanism 2 Activate the directional insertion mechanism 2, and the hydraulic cylinder 211 pushes the fixing block 26 and the plug 27 forward to the initial docking position; Confirm that the tapered guide head 29 at the front end of the guide rod 28 has extended out of the fixing plate 25 and that the buffer spring 210 is in a free state; Check the axial alignment of the guide head 29 and the guide hole 6, allowing for an angular deviation within ±5°; (3) Coarse guidance and position correction The electric boat approaches the guide plate 3 at a low speed, causing the guide head 29 to gradually enter the flared area of ​​the guide hole 6. The tapered design of the guide head 29, combined with the flared hole structure of the guide hole 6, automatically guides the guide rod 28 to move along the axis of the guide hole 6 upon contact, correcting hull sway or initial positioning deviation. The buffer spring 210 absorbs part of the impact force during compression, preventing hard contact from damaging components; (4) Precise docking and locking After the guide head 29 is fully inserted into the guide hole 6, the hydraulic cylinder 211 continues to push the fixing block 26 forward, so that the plug 27 is inserted into the plug connector body 51. The rubber retaining sleeve 511 at the bottom of the plug connector body 51 first contacts the inner cavity of the plug 27, which serves to seal and buffer. The inclined surface of slider 55 is pressed by the inner wall of plug 27, compressing spring 56 and sliding inward along rectangular groove 54, allowing the plug body 51 to continue to penetrate deeper. When the slider 55 moves to the position of the second rectangular groove 57, the spring 56 rebounds and pushes the slider 55 outward to lock into the second rectangular groove 57, thus achieving mechanical locking; At the same time, the connector 52 is fully inserted into the electrical slot 271 to complete the electrical connection; (5) Monitoring of the charging process Once docking is confirmed, the charging process is initiated via the shipborne or shore-based control system, monitoring parameters such as charging current, voltage, and temperature. If the hull experiences slight displacement due to wind and waves during charging, the positioning spring 24 absorbs the displacement through the elastic deformation of the slide rod 22 and the end plate 23, maintaining a stable connection between the plug 27 and the connector 5. (6) Separation and Reset After charging is complete, press the arc-shaped pressure strips 272 on both sides of the plug 27 inward, push the locking block 273 to squeeze the slider 55, and make it disengage from the rectangular groove 2 57. Hydraulic cylinder 211 retracts, causing plug 27 to separate from connector body 51, and rubber retaining sleeve 511 exits with plug 27. The guide head 29 retracts to its initial position, the directional insertion mechanism 2 returns to standby status, and the electric boat leaves the charging area.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Self-correcting guidance system: This invention, through the cooperation of a tapered guide head and a flared guide hole, along with a buffer spring at the rear end of the guide rod, can automatically correct the docking position deviation caused by sea waves, ensuring precise alignment of the charging interface, while effectively absorbing docking impact and improving the stability of the equipment in a wave environment. 2. Reliable connection and quick disconnection: When the plug is inserted, the slider is squeezed by the inclined plane and moves towards the opposite side, compressing the spring. After it is fully inserted, the spring rebounds and the slider is locked into the second rectangular groove, forming a stable limit. Secondly, through the lever action of the arc-shaped pressure bar and the locking block, the locking of the slider and the rectangular groove can be quickly released, achieving efficient separation. Furthermore, the hydraulic cylinder can independently control the movement of the fixed block, ensuring that the mating pressure between the plug and the connector is stable and controllable.

A fixed block 26 is provided on the front side of the fixed plate 25. A plug 27 is fixedly mounted on the fixed block 26. The plug 27 corresponds one-to-one with the interface 4. Guide rods 28 corresponding to guide holes 6 are provided on the front side of the fixed plate 25 and on both sides of the plug 27. A guide head 29 is provided at the front end of the guide rod 28. The guide head 29 is conical. There are two slide rods 22. There are four sets of positioning springs 24. The guide hole 6 is provided on the guide hole plate 7. The guide hole plate 7 is detachably fixed on the guide plate 3. The guide head 29 is detachably slidably mounted on the front end of the guide rod 28. A buffer spring 210 is provided on the rear side of the guide head 29 and on the guide rod 28. A hydraulic cylinder 211 is provided between the fixing block 26 and the fixing plate 25. The fixing block 26 is fixedly installed at the output end of the hydraulic cylinder 211, and the end of the hydraulic cylinder 211 is fixedly installed on the front side of the fixing plate 25. like Figure 4 , Figure 5 Figure 6 and Figure 7As shown, plug 27 is connected to connector 5. Connector 5 includes connector body 51, with connector 52 fixedly connected to the top of connector body 51. Sleeves 53 are fixedly connected to both sides of connector body 51. A contact groove 271 adapted to connector 52 is provided at the top of the inner cavity of plug 27. Rectangular grooves 54 are provided on both sides of sleeve 53. Slider 55s are slidably connected to the inner cavity of rectangular grooves 54. Multiple springs 56 are welded to opposite sides of the two sliders 55. The ends of springs 56 away from sliders 55 are welded to the inner wall of rectangular grooves 54. Rectangular grooves 57 adapted to sliders 55 are provided at the bottom of both sides of plug 27. A cable 58 is provided at the bottom of connector body 51. The top of cable 58 extends through to the top of connector body 51 and is electrically connected to connector 52. The side of slider 55 away from spring 56 is sloped. Arc-shaped pressure strips 272 are fixedly connected to the top of both sides of the plug 27. A locking block 273 is fixedly connected to the bottom of the opposite side of each of the two arc-shaped pressure strips 272, and the opposite side of each locking block 273 is in contact with the slider 55. Limiting protrusions 59 are fixedly connected to the top and bottom of the slider 55. Rectangular grooves 510, which are adapted to the limiting protrusions 59, are opened at the top and bottom of the inner cavity of the rectangular groove 54. A rubber retaining sleeve 511 is glued to the bottom of the plug connector body 51, and the rubber retaining sleeve 511 is fitted onto the surface of the cable 58.

[0020] This invention utilizes the inclined surfaces of two sliders 55 facing away from each other. As the sliders 55 move upwards, the inclined surfaces are pressed against the plug 27, causing them to move towards each other and directly engage with the inner cavity of the second rectangular groove 57. The combination of the limiting protrusion 59 and the third rectangular groove 510 provides limiting and guiding for the sliders 55, improving their stability during sliding. The combination of the arc-shaped pressure strip 272 and the locking block 273 pushes the sliders 55, making the release of the sliders 55 from the second rectangular groove 57 more convenient and quick, increasing the practicality of the connection. The rubber fixing sleeve 511 prevents the cable 58 from breaking due to bending during use, greatly extending its service life.

[0021] Working principle of the invention: In use, the electric boat moves the waterproof box 1 close to the guide plate 3, and the guide head 29 is aligned with the guide hole 6. Even if the guide head 29 is slightly off-center from the center of the guide hole 6 due to the strong winds and waves at sea, the guide head 29 is conical because the inner end of the guide hole 6 is a flared hole. The fit between the guide head 29 and the guide hole 6 can automatically correct the fit position. Then, the rubber fixing sleeve 511, along with the plug connector body 51, is inserted into the inner cavity of the plug 27. When the slider 55 contacts the inner wall of the plug 27, the two sliders 55 are squeezed and move towards each other, compressing the spring 56. When the slider 55 is fully inside the inner cavity of the plug 27, the spring 56 rebounds, and the two sliders 55 move back to their original state and enter the inner cavity of the rectangular groove 2 57, thus limiting the plug connector body 51. At the same time, the connecting connector 52 is also fully inside the inner cavity of the electrical groove 271, completing the fit.

[0022] After completion, the two arc-shaped pressure strips 272 can be pressed inward to make them move towards each other. The locking block 273 is pushed and the two 273s move towards each other, thereby causing the two sliders 55 to move towards each other, releasing the engagement with the rectangular groove 57. At the same time, the rubber fixing sleeve 511 is pulled outward to separate the connecting joint 52 from the electrical groove 271 and the plug-in connector body 51 from the plug 27.
