This equipment provides berthing vessels with a fast and safe standard shore power interface, ensuring stable and efficient access to shore power during berthing. Furthermore, shore power boxes offer diverse functions such as branch power supply, data acquisition, billing, and settlement, enhancing the intelligence level of port power supply and effectively reducing carbon emissions and noise pollution during vessel berthing, thus contributing significantly to creating a green and environmentally friendly port environment.

[0003] Currently, shore power boxes are equipped with interlocking devices during use. These interlocking devices are crucial for ensuring a safe and reliable connection between the shore power box and the ship's power supply system. They effectively prevent load activation due to misoperation, thereby eliminating potential safety hazards in the shore power system. The most basic form of interlocking device is a door lock, which can be easily opened with a key. Similarly, this type of interlocking device is also applied to the box body and sealed door of the shore power box. However, these interlocking devices rely primarily on keys for operation; if the key is lost, the interlocking device cannot be opened. Consequently, opening the shore power box becomes extremely inconvenient and difficult. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a shore power box interlocking device, including an interlocking mechanism 1, a shore power box body 2 is provided on one side of the interlocking mechanism 1, the interlocking mechanism 1 includes a docking block 4, a fixing block 5, a locking block 6, a spring 7, a mounting block 3, a connecting rod 8 and a snap-fit ​​groove 9, the docking block 4 is connected to one side of the sealing door of the shore power box body 2, the sealing door hinge is on the box shell of the shore power box body 2, the fixing block 5 is connected to the outer wall of the box shell of the shore power box body 2, the spring 7 is assembled inside the fixing block 5, the mounting block 3 is connected to one end of the spring 7, the connecting rod 8 is connected to one end of the mounting block 3, the snap-fit ​​groove 9 is opened on the side wall of the locking block 6, the snap-fit ​​groove 9 is adapted to the size of the docking block 4, the end of the connecting rod 8 is connected to the back end of the locking block 6, the docking block 4 can form an elastic snap-fit ​​connection with the fixing block 5 through the locking block 6, the connecting rod 8, the mounting block 3 and the spring 7.

[0023] In practical use, when it is necessary to close the sealing door of the shore power box body 2 for protection and interlocking, firstly, rotate the sealing door along the central axis of the hinge, causing the docking block 4 to move closer to the fixing block 5. When the docking block 4 approaches the locking block 6, the operator pushes the locking block 6 to move it towards the fixing block 5. During this movement, the locking block 6 will cause the connecting rod 8 to compress the spring 7, resulting in the spring 7 undergoing contraction deformation. At the same time, the movement of the locking block 6 also releases the obstruction to the docking block 4. At this time, the operator rotates the docking block 4 to make it fit tightly against the outer shell of the shore power box body 2. Next, the operator releases the pushed locking block 6. Under the elastic action of the spring 7, the locking block 6 will return to its original position. After returning to its original position, the locking block 6 covers the outside of the docking block 4 through its snap-fit ​​groove 9, thereby fixing the docking block 4. The fixing of the docking block 4 securely locks the sealing door, effectively preventing accidental opening and ensuring the safety of the electrical components inside the shore power box 2. Conversely, to open the sealing door, the operator must first push the locking block 6, causing it to compress the spring 7 again and release the fixing of the docking block 4. Then, the docking block 4 is rotated away from its position against the outer shell of the shore power box 2, moving away from the fixing block 5 as the sealing door moves. Finally, the sealing door is opened by rotating it along the central axis of the hinge. This significantly improves the ease of operation of the interlocking device.

[0024] Preferably, the back end of the fixing block 5 is connected to a protrusion 10, which penetrates the fixing block 5 and fits against one end of the spring 7. The surface of the protrusion 10 is provided with a mating groove 14. The back end of the fixing block 5 is provided with an adjusting sleeve 11. The interior of the adjusting sleeve 11 is connected to a first threaded rod 12 and a second threaded rod 13. The first threaded rod 12 and the second threaded rod 13 are threadedly connected to the adjusting sleeve 11. The threads of the first threaded rod 12 and the second threaded rod 13 are opposite. The surfaces of the first threaded rod 12 and the second threaded rod 13 are both connected to sliders 15. The back end of the fixing block 5 is provided with a sliding groove 16, and the sliders 15 are fitted into the sliding groove 16. Both the sliding groove 16 and the sliders 15 are "T" shaped.

[0025] In practical use, when the operator rotates the adjusting sleeve 11 clockwise, the adjusting sleeve 11 drives the first threaded rod 12 and the second threaded rod 13 to move closer together until they retract into the interior of the adjusting sleeve 11. During this movement, the first threaded rod 12 and the second threaded rod 13 drive the slider 15 to slide along the slide groove 16. This engagement between the slider 15 and the slide groove 16 effectively prevents the first threaded rod 12 and the second threaded rod 13 from rotating with the adjusting sleeve 11. As the first threaded rod 12 and the second threaded rod 13 move closer together, they move out of the mating groove 14, thereby releasing the fixation on the protrusion 10. At this time, the operator can remove the protrusion 10. Removing the protrusion 10 exposes the spring 7 inside the fixing block 5. In this way, when the spring 7 becomes less elastic after long-term use, the operator can easily disassemble and replace it, thereby further improving the convenience of replacement. Conversely, when the operator rotates the adjusting sleeve 11 counterclockwise, the first threaded rod 12 and the second threaded rod 13 move away from each other. After the protrusion 10 is inserted into the opening at the back end of the fixing block 5, the first threaded rod 12 and the second threaded rod 13 can be re-inserted into the mating groove 14, thereby fixing the protrusion 10.

[0026] Working principle: First, the interlocking mechanism 1 is installed on the shore power box body 2. When operating the interlocking mechanism 1, the operator rotates the sealing door along the central axis of the hinge, causing the docking block 4 to gradually approach the locking block 6 as the sealing door moves. When the docking block 4 approaches the locking block 6, the operator pushes the locking block 6 towards the fixing block 5. During this process, the locking block 6 drives the connecting rod 8 to compress the spring 7, causing the spring 7 to contract and deform. At the same time, the movement of the locking block 6 also releases the obstruction to the docking block 4. Next, the operator rotates the docking block 4 again, making it fit tightly against the outer shell of the shore power box body 2. Then, the operator releases the locking block 6. Under the elastic action of the spring 7, the locking block 6 returns to its original position, and the snap-fit ​​groove 9 on it covers the outside of the docking block 4, thus fixing the docking block 4. The fixing of the docking block 4 ensures that the sealing door is firmly locked, effectively preventing the sealing door from being opened accidentally, thereby ensuring the safety of the electrical components inside the shore power box body 2. This design significantly improves the ease of operation of the interlocking device.

[0027] It is worth noting that the shore power box body 2 plays an indispensable and crucial role in the entire technical solution outlined in this document. The model of the shore power box body 2 is AZ10. This model of punch press is a mature existing technology, and therefore will not be elaborated upon further in this document.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
