Detailed implementation manners

[0019] The following further describes the present application in detail with reference to the Figure 1 - attached Figure 11 drawings.

[0020] The embodiment of the present application discloses a shore power charging device and a charging method.

[0021] Embodiment 1, referring to Figure 1 and Figure 2, A shore power charging device includes a base 1 installed on a ship, a first power interface 3 provided on the base 1, a first cover plate 34 slidable relative to the base 1, a power supply box provided on the shore, a second power interface 4 communicating with the power supply box, and two second cover plates 44 movable relative to the second power interface 4. The first power interface 3 is connected to the ship power supply, and the first power interface 3 and the second power interface 4 are electrically connected by a plug-in method. When not charging, the first cover plate 34 covers the connection part of the first power interface 3, and the two second cover plates 44 cover the connection part of the second power interface 4. This can effectively prevent external environmental factors, such as rain, dust, salts in the marine environment, and other sundries, from entering the connection part of the power interface, avoiding electrical failures such as corrosion and short circuits at the interface caused by the intrusion of these foreign objects, greatly extending the service life of the interface, and ensuring the overall reliability of the shore power charging device; it also reduces the possibility of personnel accidentally touching the live interface in the non-charging state, reducing the hidden danger of safety accidents such as electric shock, and playing a good protective role in the personal safety of personnel working around the ship and shore dock workers.

[0022] Reference Figure 2 , Figure 3 and Figure 4 , The first power interface 3 includes a socket 31, a first cover plate 34, several guide posts 11 fixedly connected to the base 1, a slot body 32 slidably connected to the guide posts 11, and a first power source 33 installed on the base 1. In Embodiment 1, the first power source 33 is taken as an air cylinder. The output end of the air cylinder is fixedly connected to the slot body 32, so that the slot body 32 can move on the guide posts 11; the slot body 32 is provided with a tapered groove 35 adapted to the second power interface 4. In Embodiment 1, the tapered groove 35 is formed by splicing two quadrangular pyramid grooves, and the clamping angle formed by the two inclined surfaces where the two quadrangular pyramid grooves are connected is 170°. In this way, the lower quadrangular pyramid groove has a better supporting effect. When docking with the second power interface 4, it can provide stable and reliable support for the inserted interface part, ensuring that the interface will not easily shake or shift due to external forces and other factors after connection, guaranteeing the stability of the power interface during the charging process, and being beneficial to the continuous and stable transmission of electric energy; the tapered groove 35 extends downward from the top surface of the slot body 32 and completely penetrates to the bottom surface of the slot body 32, and the side with the larger opening of the tapered groove 35 is located at the top of the slot body 32; The second power supply interface 4 includes a plug connector 6, a housing 41 adapted to the tapered slot 35, and a guide wheel 42 mounted on the outside of the housing 2. When the housing 41 is inserted into the tapered slot 35, the guide wheel 42 can abut against the inner wall of the tapered slot 35. During the process of the housing 41 falling and inserting into the tapered slot 35, relying on the abutting action between the guide wheel 42 mounted on the outside of the housing 41 and the inner wall of the tapered slot 35, the housing 41 can be aligned with the center position of the tapered slot 35. This automatic centering mechanism greatly improves the accuracy of the power supply interface docking, ensures accurate positioning every time of insertion, and avoids problems such as poor contact and virtual connection of the interface caused by position deviation, thus ensuring stable and efficient transmission of electric energy during shore power charging and reducing potential faults such as heating and arcing caused by poor connection; during the process of the guide wheel 42 contacting the inner wall of the tapered slot 35, it plays a buffering and guiding role. Compared with the rigid docking without the guide wheel 42, it can effectively prevent the housing 41 from directly colliding and rubbing violently with the tapered slot 35, reduce the wear of the interface components caused by multiple pluggings and unpluggings, extend the service life of the power supply interface, reduce the cost of replacement and repair due to frequent damage of the interface components, and ensure the long-term stable and reliable operation of the shore power charging device.

[0023] Reference Figure 5 , the guide post 11 is fixedly connected to the housing 2. The housing 2 is located between the slot body 32 and the socket 31. Two pulleys 22 are installed on both sides of the first cover plate 34. The housing 2 is provided with two slide rails 21. The pulley 22 can move along the slide rail 21. A second power source 23 is arranged in the housing 2. In Embodiment 1, the second power source 23 is taken as an air cylinder for example. The second power source 23 can drive the first cover plate 34 to move.

[0024] Reference Figure 2 、 Figure 5 and Figure 6, the housing 41 is provided with a slot hole 43 communicating with the interior. The top end of the socket body 32 is provided with a ring 322. Five elastic pieces 323 distributed annularly in position are fixedly connected to the top surface of the ring 322. The top end of the elastic piece 323 is provided with an inclined platform 3231. The elastic piece 323 and the ring 322 can extend into the slot hole 43. The socket body 32 is fixedly connected with a first mounting member 321. In Embodiment 1, the first mounting member 321 is formed by welding multiple plate members. The first cover plate 34 is rotatably connected with a first connecting rod 5. The end of the first connecting rod 5 is rotatably connected with a first vertical rod 51. The first vertical rod 51 is fixedly connected with a first abutting platform 512. A first spring 511 is arranged between the first abutting platform 512 and the first mounting member 321. The first spring 511 forces the first vertical rod 51 to move upward. The first vertical rod 51 sequentially penetrates through the socket body 32, the first mounting member 321, and the ring 322. After the housing 41 and the socket body 32 are mated, the first cover plate 34 is driven to move by the second power source 23. Then, by means of a series of transmission structures such as the first connecting rod 5 and the first vertical rod 51, the inclined platform 3231 of the elastic piece 323 is pushed to cause the elastic piece 323 to deform outward, achieving the effect of locking the housing 41 and the plug-in slot. This locking mechanism can effectively prevent the interface from accidentally loosening or detaching due to factors such as the shaking of the ship and external force pulling during the charging process, ensuring the stability of the connection between the shore power charging power interfaces, ensuring that the electric energy can be transmitted continuously and stably, and avoiding problems such as poor contact and power-off caused by loose connection; by using components such as the ring 322, the elastic piece 323 on the socket body 32, and the first connecting rod 5, the first vertical rod 51, and the first spring 511 associated with the first cover plate 34, a set of compact and mutually cooperative locking structures is constructed. The components are cleverly connected and interact with each other, realizing complex and effective functions within a limited space, neither affecting the normal docking process of the interface nor failing to play the locking role in a timely manner when needed, reflecting the rationality and efficiency of the structural design.

[0025] Reference Figure 7 and Figure 8 , a second mounting member 521 is fixedly connected inside the housing 41. In Embodiment 1, the second mounting bracket takes a pipe fitting as an example. The second mounting member 521 is slidably connected with a second vertical rod 52. The end of the second vertical rod 52 is rotatably connected with a second connecting rod 53. The second mounting member 521 is provided with an avoidance groove for avoiding the second connecting rod 53. A second spring 522 is arranged between the end of the second vertical rod 52 and the inner wall of the second mounting member 521. The second spring 522 forces the second vertical rod 52 to move downward. The second mounting member 521 is located above the slot hole 43. The end of the second connecting rod 53 is rotatably connected with a first cross rod 54. The first cross rod 54 is slidably connected with the housing 41. The end of the first cross rod 54 is rotatably connected with a third connecting rod 55. A moving plate 56 is slidably connected to the housing 41 in the vertical direction. The moving plate 56 is rotatably connected with the third connecting rod 55.

[0026] After the elastic piece 323 and the circular ring 322 can extend into the slot hole 43, they are both located below the second mounting member 521. After the elastic piece 323 expands outwards, the first vertical rod 51 can continue to move upwards and extend into the second mounting member 521. The first vertical rod 51 can push the second vertical rod 52 to move upwards. The second vertical rod 52, the second connecting rod 53, the first cross rod 54, the third connecting rod 55 and the moving plate 56 form a connecting rod mechanism, so that the moving plate 56 can move up and down in the housing 41. The second spring 522 mainly plays a reset role. When placed normally, the second spring 522 applies a downward force to the second vertical rod 52. Under the action of the connecting rod mechanism, the moving plate 56 is in the lowest position.

[0027] Reference Figure 9 , there are two baffles 45 at the bottom opening of the housing 41. The second cover plate 44 abuts against the baffle 45. The second cover plate 44 is rotatably connected with a first driving member 46. In Embodiment 1, the first driving member 46 is composed of a plate member and a rod member rigidly connected to form a symmetric part. The first driving member 46 is fixedly connected with the moving plate 56. The projection of the first driving member 46 and the second cover plate 44 in the vertical direction is located on the baffle 45. The length direction of the baffle 45 is parallel to the arrangement direction of the plug connectors 6. When placed normally, the two second cover plates 44 are in a mutually abutting and closed state. When the moving plate 56 moves upwards, the first driving member 46 will simultaneously pull up the ends of the two cover plates. The second cover plate 44 tilts upwards. One side of the second cover plate 44 abuts against the side of the baffle 45. The second cover plate 44 rotates relative to the baffle 45, effectively preventing interference with other components when the second cover plate 44 is pulled outwards. When the first driving member 46 moves downwards, the first driving member 46 will push the second cover plate 44 to move and rotate along the baffle 45 until the two second cover plates 44 are in a parallel and closed state.

[0028] Reference Figure 10, the plug connector 6 includes a first housing 61 fixedly connected to the housing 41, a second housing 62 sleeved on the first housing 61, a first plastic part 63 slidably connected to the first housing 61, a second plastic part 64 fixedly connected to the second housing 62, a first conductive part 65 fixedly connected to the first plastic part 63, and a second conductive part 66 fixedly connected to the second plastic part 64. The first conductive part 65 is electrically connected to the power supply box, and the second conductive part 66 can be electrically connected to the socket 31. When the second housing 62 moves, the first conductive part 65 and the second conductive part 66 can achieve electrical connection. A third spring 67 is provided between the first housing 61 and the second housing 62. The third spring 67 forces the end of the second housing 62 away from the first housing 61. The second housing 62 is connected to the moving plate 56 through a second driving member 47. In Embodiment 1, the first conductive part 65 and the second conductive part 66 are made of conductive metal, with one end being a male plug and the other end being a female socket. In the initial state, the moving plate 56 is at the lowest position. At this time, the first housing 61 and the second housing 62 are in a separated state, and the first conductive part 65 and the second conductive part 66 are in a power-off state. After the housing 41 and the plug-in body are plugged together, the moving plate 56 will drive the second housing 62 to move upward, so that the first conductive part 65 and the second conductive part 66 are connected. This makes the second conductive part 66 in a power-off state during normal placement. Since the second conductive part 66 is in contact with air for a long time, if it is always in a powered-on state, the corrosion rate of the second conductive part 66 will be accelerated; the sea air also contains salt. Even if not in the sea, the sea breeze will carry tiny salt particles in the sea water, and these salt particles will deposit on the surface of objects. When the humidity in the air is relatively high, the salt particles will dissolve to form an electrolyte solution containing salt. Taking sodium chloride as an example, it will ionize into sodium ions and chloride ions in the solution and is prone to electrochemical corrosion on the second conductive part 66.

[0029] Reference Figure 10, the first conductive member 65 is provided with a cable plugging portion 651. Both the first conductive member 65 and the first plastic member 63 are provided with mutually communicating notch openings 636. A plurality of clamping blocks 634 are rotatably connected within the first plastic member 63. At least a part of the clamping blocks 634 can extend into the cable plugging portion 651. Inside the first housing 61, there is a trigger platform which abuts against the clamping blocks 634. The first plastic member 63 is provided with a sliding groove 631. A slider 632 is slidably connected within the sliding groove 631. The slider 632 is fixedly connected to a pull rod 633. The pull rod 633 is slidably connected to the clamping blocks 634. A fifth spring 69 is provided between the slider 632 and the inner wall of the sliding groove 631. The fifth spring 69 forces the pull rod 633 to retract into the sliding groove 631. At the tail end of the first housing 61, there is also a tightening nut. When connecting the cable to the plug head, first pass the cable through the tightening nut and expose the conductive parts of each sub-cable. Insert the conductive parts of the sub-cables into the cable plugging portion 651 of the first conductive member 65. After all the sub-cables are plugged in, forcefully push the entire cable, causing the first plastic member 63 to move within the first housing 61. During the movement of the first plastic member 63, the clamping blocks 634 will rotate under the abutting action of the trigger platform, enabling the clamping blocks 634 to clamp the sub-cables in the cable plugging portion 651. Preferably, rotate and screw the tightening nut into the end of the first housing 61 to fix the first housing 61 to the cable. In this way, the first conductive member 65 and the clamping blocks 634 inside the first housing 61 are still in a clamped state. This enables the rapid connection of the cable to the plug 6. A fourth spring 68 is provided between the first plastic member 63 and the first housing 61. The fourth spring 68 forces the first plastic member 63 to move towards the cable. In this way, when the cable is pulled out, the fourth spring 68 can reset the first plastic member 63.

[0030] Reference Figure 10 , a plurality of fourth connecting rods 635 are rotatably connected to the first plastic member 63. A plurality of first rotating rods 6351 are rotatably connected to the inner wall of the first housing 61. The end of the first rotating rod 6351 is rotatably connected to a second rotating rod 6352. The fourth connecting rod 635 is rotatably connected to the first rotating rod 6351. A rubber ring 6353 is sleeved on the first rotating rod 6351 and the second rotating rod 6352. One section of the rubber ring 6353 is fixed to the inner wall of the first housing 61. When the first plastic member 63 moves, it will drive the first rotating rod 6351 to rotate through the fourth connecting rod 635. Since one end of the second rotating rod 6352 abuts against the cable and cannot rotate, the first rotating rod 6351 and the second rotating rod 6352 will bend, increasing the contact area between the rubber ring 6353 and the cable and enhancing the sealing performance at the tail of the first housing 61.

[0031] Example 2, reference Figure 11 , a charging method, the specific method includes: Charging Preparation: The ship is docked at the designated onshore power charging position on the shore, ensuring the stability of the ship's position for subsequent onshore power connection operations; before connection, check the first power interface 3 on the ship and the second power interface 4 on the shore respectively to ensure that there is no debris or damage at the interface, the first cover plate 34 covers the connection of the first power interface 3, and two second cover plates 44 cover the connections of the second power interface 4; connect one end of the cable of the onshore power charging device to the power supply box on the shore, ensure the connection is firm, and there is no damage or leakage in the cable; Interface Docking: Start the first power source 33 to move the slot body 32 on the guide post 11, and adjust the slot body 32 of the first power interface 3 to a position convenient for plugging into the second power interface 4; align the housing 41 of the second power interface 4 with the conical groove 35 of the first power interface 3, and slowly lower and insert it. During the lowering process, relying on the abutting effect of the guide wheel 42 on the outer side of the housing 41 and the inner wall of the conical groove 35, the housing 41 and the conical groove 35 are automatically centered to ensure accurate interface plugging; Interface Locking: When the housing 41 and the slot body 32 are successfully mated, start the second power source 23 in the mounting shell 2 to drive the first cover plate 34 to move; the movement of the first cover plate 34 passes through a series of transmission structures such as the first connecting rod 5 and the first vertical rod 51, and pushes the inclined platform 3231 of the elastic piece 323 to cause the elastic piece 323 to deform outward, realizing locking the housing 41 and the plugging groove; Circuit Connection: At the same time as the housing 41 and the slot body 32 are locked, the first vertical rod 51 moves upward and extends into the second mounting member 521, pushing the second vertical rod 52 upward. Through the link mechanism composed of the second vertical rod 52, the second connecting rod 53, the first cross rod 54, the third connecting rod 55 and the moving plate 56, the moving plate 56 moves upward in the housing 41; the upward movement of the moving plate 56 drives the second housing 62 to move upward against the force of the third spring 67, so that the first conductive member 65 and the second conductive member 66 are connected, thus realizing the electrical connection between the onshore power supply box and the ship power supply; Charging Completion: When the ship's charging is completed, start the second power source 23 to move the first cover plate 34 in the reverse direction, relieve the extrusion of the elastic piece 323, and the elastic piece 323 returns to its original state. Then, pull out the housing 41 of the second power interface 4 from the conical groove 35 of the first power interface 3; during the process of pulling out the housing 41, the moving plate 56 moves downward, driving the second cover plate 44 to return to the initial closed state, and the first cover plate 34 also returns to the initial position to cover the connection of the first power interface 3.
