Description
Technical Field
[0001] This utility model relates to the field of marine equipment technology, specifically to a shore power charging interface structure for ships. Background Technology
[0002] Shore power refers to a technology system that allows ships to stop using their own diesel generators or other self-provided power sources while berthing in port, and instead obtain electrical energy from the port's landside power grid through dedicated cables, interfaces, and control equipment to meet the ship's power needs for power, lighting, communication, cargo loading and unloading, air conditioning, etc. during their stay in port. In existing technologies, shore power charging connectors are generally installed at the front edge of the port wharf. They are usually distributed according to the layout of the wharf and the location of the ships to facilitate the connection of the ships to shore power after they dock. Since the shore power charging interface is located on the water-closed shore, the environment is humid and water can easily enter, leading to accidents such as short circuits. Even if the current shore power connectors are hinged with covers, such waterproof design may not be perfect. Water vapor can still enter the connector through gaps, resulting in poor sealing and making it difficult to guarantee safety. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a ship shore power charging interface structure, which solves the technical problem that the sealing and waterproofing effect at the shore power charging connector in the prior art is not good and it is difficult to ensure safety.
[0004] According to one aspect, at least one embodiment of the present invention provides a shore power charging interface structure for a ship, including a shore power box, a charging connector on the shore power box, a protective shell, a protective plate, a sealing cover, a waterproof sleeve, and a fixing component. The protective shell is fitted and fixed to the charging connector. The protective plate is hinged to the protective shell via a hinge. A through groove is formed on the protective plate to cooperate with the sealing cover. The sealing cover is movably disposed on the protective plate via a moving mechanism. The waterproof sleeve is coaxially fixed inside the sealing cover for cooperating with the protective plate, the sealing cover, and the moving mechanism to abut against the charging connector. The fixing component is disposed on the charging connector for fixing the sealing cover.
[0005] Preferably, the moving mechanism includes a push rod, a connecting plate, and a handle. One end of the push rod passes through the protective plate and is coaxially and fixedly connected to the sealing cover. The push rod is slidably engaged with the protective plate. One end of the connecting plate is fixedly connected to the other end of the push rod, and the handle is fixedly connected to one end of the connecting plate.
[0006] Furthermore, the fixing component includes an abutment ring, a insert plate, a limiting plate, a socket, and a snap-fit groove. The abutment ring is fitted onto the charging connector and is coaxially and fixedly connected to the charging connector. One end of the insert plate is fixedly connected to the sealing cover, and one end of the limiting plate is fixedly connected to the other end of the insert plate. The limiting plate and the insert plate form an L-shape. The abutment ring has a socket that mates with the limiting plate, and the abutment ring has a snap-fit groove that mates with the insert plate and the limiting plate.
[0007] Furthermore, in order to fix the sealing cover inside the protective plate and the protective shell, the other end of the connecting plate is detachably connected to the protective plate by bolts.
[0008] As a further aspect of this application, in order to increase the sealing of the connection between the push rod and the protective plate, a rubber sleeve is provided at the connection between the push rod and the protective plate, and the rubber sleeve abuts against the push rod.
[0009] As a further embodiment of this application, in order to enable the protective plate to rotate and abut against the protective shell, the sealing cover is located in the through groove and coincides with the axis of the charging connector. After the protective shell and the protective plate abut against each other, the charging connector and the sealing cover are coaxially arranged.
[0010] Based on the aforementioned scheme, in order to enable the sealing cover to drive the insert plate and the limiting plate to rotate within the abutment ring, so that the limiting plate is engaged within the abutment ring, one end of the insert plate and the limiting plate are both arc-shaped, and the engaging groove is fan-shaped.
[0011] Furthermore, in order to ensure that the sealing cover can be supported and guided by the inner wall of the through groove as it moves toward the charging connector, the length of the through groove is the same as the width of the waterproof sleeve.
[0012] The beneficial effects of this utility model are as follows: In this utility model, by cooperating with the protective shell, protective plate, sealing cover, waterproof sleeve, moving mechanism and fixing components, when the shore power box is not in use, the bolts are loosened to "release" the restriction on the connecting plate, and the handle is held and the sealing cover is fully inserted into the through groove. The handle is kept stable and the protective plate is rotated so that the protective plate abuts against the protective plate (4). By holding the handle and pushing the handle close to the charging connector, the waterproof sleeve is moved to waterproof one end of the charging connector, and the plug plate and the limiting plate are inserted into the snap-fit groove through the plug hole. By rotating the handle, the limiting plate is "restricted" in the snap-fit groove, and the connecting plate is just in the position fixed to the protective plate by the bolts. Then the bolts are used to fix the protective plate and the connecting plate. In this way, the protective shell and the protective plate can be tightly attached and fixed, and the charging connector is sealed and waterproofed, and it is also protected from collisions with external debris.

[0022] like Figures 1-5As shown, it illustrates a shore power charging interface structure for a ship according to an embodiment of the present invention, including a shore power box 1, which is installed on the shore and has a charging connector 2. It also includes a protective shell 3, a protective plate 4, a sealing cover 6, a waterproof sleeve 8, and a fixing component. The protective shell 3 is fitted and fixed on the charging connector 2. The protective shell 3 is hinged to the protective plate 4 by the hinge 5. By rotating the protective plate 4, the protective plate 4 is opened, so that the charging connector 2 can be connected to the outside world and the ship can be charged by connecting to the cable. like Figure 3 As shown, the protective plate 4 has a through groove 7 that matches the sealing cover 6. The sealing cover 6 is slidably disposed in the through groove 7. In order to allow the protective plate 4 to rotate and abut against the protective shell 3, the sealing cover 6 is located in the through groove 7 and coincides with the axis of the charging connector 2. After the protective shell 3 and the protective plate 4 abut against each other, the charging connector 2 and the sealing cover 6 are coaxially disposed. The sealing cover 6 is movably disposed on the protective plate 4 through a moving mechanism. In order to allow the sealing cover 6 to be supported and guided by the inner wall of the through groove 7 during the process of moving towards the charging connector 2, the length of the through groove 7 is the same as the width of the waterproof sleeve 8. like Figure 2 and Figure 3 As shown, the moving mechanism includes a push rod 9, a connecting plate 10, and a handle 11. One end of the push rod 9 passes through the protective plate 4 and is coaxially and fixedly connected to the sealing cover 6. The push rod 9 and the protective plate 4 are slidably engaged. In order to increase the sealing of the connection between the push rod 9 and the protective plate 4, a rubber sleeve 18 is provided at the connection between the push rod 9 and the protective plate 4. The rubber sleeve 18 abuts against the push rod 9. One end of the connecting plate 10 is fixedly connected to the other end of the push rod 9. A handle 11 is fixedly connected to one end of the connecting plate 10. In order to fix the sealing cover 6 inside the protective plate 4 and the protective shell 3, the other end of the connecting plate 10 is detachably connected to the protective plate 4 by bolts 17. It should be added that when the protective plate 4 is not rotated and is in contact with the protective shell 3, the connecting plate 10 and the protective plate 4 are fixed by bolts 17 to maintain the stability of the sealing cover 6. By unscrewing the bolts 17, the restriction on the connecting plate 10 is "released". Hold the handle 11 and move the push rod 9 away from the protective plate 4. The push rod 9 moves the sealing cover 6 completely into the through groove 7. At this time, part of the push rod 9 is outside the protective plate 4, and the connecting plate 10 is not in contact with the protective plate 4. Then, keep the handle 11 stable and rotate the protective plate 4 so that the protective plate 4 is in contact with the protective plate 4. At this time, both the protective plate 4 and the protective shell 3 are in a horizontal state. A waterproof sleeve 8 is coaxially fixed inside the sealing cover 6. It is used to cooperate with the protective plate 4, the sealing cover 6 and the moving mechanism to abut against the charging connector 2. By holding the handle 11 and pushing the handle 11 close to the charging connector 2, the handle 11 drives the connecting plate 10 to move. The connecting plate 10 drives the push rod 9 to move. The push rod 9 pushes the sealing cover 6 along the inner wall of the through groove 7 toward the charging connector 2, and drives the waterproof sleeve 8 to abut against the outer wall of the charging connector 2. When the connecting plate 10 abuts against the protective plate 4, the waterproof sleeve 8 waterproofs one end of the charging connector 2. like Figure 2 , Figure 3 and Figure 4 As shown, a fixing assembly is installed on the charging connector 2 to fix the sealing cover 6. The fixing assembly includes an abutment ring 12, a insert plate 13, a limiting plate 14, a socket 15, and a snap-fit groove 16. The abutment ring 12 is fitted onto the charging connector 2 and is coaxially and fixedly connected to the charging connector 2. One end of the insert plate 13 is fixedly connected to the sealing cover 6, and one end of the limiting plate 14 is fixedly connected to the other end of the insert plate 13. The limiting plate 14 and the insert plate 13 form an L-shape. The abutment ring 12 has a groove for engaging with the limiting plate 15. The four-part socket 15 has a locking groove 16 on the abutment ring 12 that mates with the insert plate 13 and the limiting plate 14. The locking groove 16 communicates with the socket 15. In order for the sealing cover 6 to drive the insert plate 13 and the limiting plate 14 to rotate within the abutment ring 12, so that the limiting plate 14 is locked within the abutment ring 12, one end of the insert plate 13 and the limiting plate 14 are both arc-shaped, and the locking groove 16 is fan-shaped. When the sealing cover 6 moves toward the charging connector 2, the sealing cover 6 drives the insert plate 13. The limiting plate 14 moves toward the socket 15. When the connecting plate 10 abuts against the protective plate 4, the waterproof sleeve 8 waterproofs one end of the charging connector 2. The plug plate 13 and the limiting plate 14 enter the snap-fit groove 16 through the socket 15. By turning the handle 11, the handle 11 drives the connecting plate 10 to rotate. The connecting plate 10 drives the push rod 9 to rotate. The push rod 9 drives the sealing cover 6 to rotate. The sealing cover 6 drives the plug plate 13 and the limiting plate 14 to rotate along the inner wall of the snap-fit groove 16. When the connecting plate 10 rotates 90 degrees, the plug plate 13 and the limiting plate 14 abut against the other side wall of the snap-fit groove 16. The limiting plate 14 is "restricted" in the snap-fit groove 16. The connecting plate 10 is just in the position to be fixed to the protective plate 4 by the bolt 17. Then the bolt 17 is used to fix the protective plate 4 and the connecting plate 10. In this way, the protective shell 3 and the protective plate 4 can be tightly attached and fixed. The charging connector 2 is sealed and waterproofed, and it is also protected from collisions with external debris. It should be added that, after the restriction on the connecting plate 10 is "released", before moving the push rod 9, the handle 11 needs to be rotated to make the handle 11 vertical so that the insert plate 13 and the limiting plate 14 are aligned with the slot. Working Principle: After the shore power charging interface structure finishes charging the ship, and the shore power box 1 is not in use, the restriction on the connecting plate 10 is "released" by unscrewing bolt 17. Holding handle 11 and moving push rod 9 away from protective plate 4, push rod 9 causes sealing cover 6 to fully enter through groove 7. At this time, part of push rod 9 is outside protective plate 4, and the connecting plate is not in contact with protective plate 4. Then, keeping handle 11 stable, rotate protective plate 4 so that protective plate 4 abuts against protective plate 4. Holding handle 11 and pushing it closer to charging connector 2, handle 11 moves connecting plate 10, which in turn moves push rod 9. Push rod 9 pushes sealing cover 6 along the inner wall of through groove 7 towards charging connector 2, causing waterproof sleeve 8 to abut against the outer wall of charging connector 2. When connecting plate 10 abuts against protective plate 4, waterproof sleeve... 8. Waterproof one end of the charging connector 2. During this process, the insert plate 13 and the limiting plate 14 enter the snap-fit groove 16 through the insertion hole 15. By turning the handle 11, the handle 11 drives the connecting plate 10 to rotate, the connecting plate 10 drives the push rod 9 to rotate, the push rod 9 drives the sealing cover 6 to rotate, and the sealing cover 6 drives the insert plate 13 and the limiting plate 14 to rotate along the inner wall of the snap-fit groove 16. When the connecting plate 10 rotates 90 degrees, the insert plate 13 and the limiting plate 14 are both in contact with the other side wall of the snap-fit groove 16, and the limiting plate 14 is "restricted" in the snap-fit groove 16. The connecting plate 10 is just in the position to be fixed to the protective plate 4 by the bolt 17. Then, the protective plate 4 and the connecting plate 10 are fixed with the bolt 17. In this way, the protective shell 3 and the protective plate 4 can be tightly attached and fixed, and the charging connector 2 is sealed and waterproofed, and is also protected from collisions with external debris.
