[0030] 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.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a smart shore power station with dual safety protection, comprising a cabinet 1 and a power outlet 4 installed on the right side of the cabinet 1. The cabinet 1 is the main body of the smart shore power station, used to carry internal electrical components and provide basic installation support. The power outlet 4 is used to realize electrical connection with the ship's charging plug to supply power to the ship. A shielding component 2 is provided on the right side of the cabinet 1 to cover and shield the power outlet 4. The shielding component 2 includes a support frame 24 fixedly connected to the right surface of the cabinet 1. The support frame 24 provides a sliding guide and mounting base for the shielding frame 21, ensuring stable movement of the shielding frame 21. The top of the support frame 24 is slidably connected to the shielding frame 21. The shielding frame 21 can cover and expose the power outlet 4 through sliding, forming physical isolation protection. A shielding plate 22 is fixedly connected to the top of the shielding frame 21. The shielding plate 22 can prevent falling debris and rainwater from directly impacting the power outlet 4 and the top gap of the shielding frame 21. A sealing gasket 23 is fixedly connected to the left surface of the shielding plate 22 to seal. The gasket 23 enhances the seal between the baffle 22 and the cabinet 1, preventing rainwater from seeping into the baffle frame 21 through the gap. The sealing gasket 23 is attached to the right side surface of the cabinet 1 and slidably connected to it, ensuring that the baffle 22 remains sealed as the baffle frame 21 moves. The front surface of the support frame 24 is threaded through and connected to a screw 25. The front surface of the baffle frame 21 has two sets of threaded holes that engage with the screw 25. By engaging with the two sets of threaded holes, the screw 25 can fix the baffle frame 21 to the support frame. The specific position of 24 prevents the shielding frame 21 from sliding accidentally when not in operation. The right side of the shielding frame 21 is provided with a protective component 3 for protecting the charging head during charging. The shielding frame 21 is U-shaped, and its opening faces to the left and is set opposite to the right side surface of the cabinet 1. The U-shape can form a surrounding shield for the plug-in port 4 from the top, front, back and right, and achieve all-round wrapping with the right side surface of the cabinet 1. The upper surface of the shielding plate 22 is set as an inclined surface that tilts to the right, which can guide rainwater to slide down to the right.

[0032] Reference Figure 1 , Figure 4 and Figure 5The protective component 3 includes a sliding plate 31 and a turntable 35. When not charging, the sliding plate 31 can block the upper part of the through-slot 32, preventing rainwater from contacting the power outlet 4. The right side surface of the shielding frame 21 has a through-slot 32 extending from the bottom, providing a passage for the charging cable to pass through, facilitating cable routing when the ship's charging plug is connected to the power outlet 4. The top of the inner wall of the through-slot 32 is semi-circular, which conforms to the outer wall of the cable, reducing friction between the cable and the edge of the through-slot 32 while enhancing sealing. Guide grooves 3 are provided on both the front and rear sides of the right side surface of the shielding frame 21 near the through-slot 32. 3. The guide groove 33 provides a sliding trajectory for the slide rod 34, limits the rotation range of the turntable 35 and guides it to precise positioning. The two sets of guide grooves 33 are symmetrically arranged and both are arc-shaped. The arc shape is adapted to the rotation trajectory of the turntable 35 to ensure that the slide rod 34 slides smoothly. The right side of the shielding frame 21 is provided with a sliding groove 313 at the top of the through groove 32 and on both the front and rear sides. The sliding groove 313 provides a sliding track for the slide plate 31 to ensure that the slide plate 31 moves up and down stably. The slide plate 31 is slidably connected to the inner wall of the sliding groove 313. The through groove 32 is opened and closed by sliding. When charging, it is opened to facilitate the cable passing through, and when not charging, it is closed to form protection.

[0033] Furthermore, a circular groove 38 is provided on the right side of the shielding frame 21, located on the left side of the slide groove 313. The turntable 35 is rotatably connected to the inner wall of the circular groove 38. The circular groove 38 provides installation space for the turntable 35 and restricts its rotation, ensuring rotational stability. A second through groove 312 is provided on the top left and right sides of the turntable 35. The second through groove 312 and the first through groove 32 cooperate to form a cable passage. The design of the circular hole in the middle enhances the protection of the cable. The bottom of the inner wall of the second through groove 312 is set as a semi-circular arc, which cooperates with the semi-circular arc of the first through groove 32 to fit the cable from the top and bottom sides, reducing gaps and avoiding cable wear. A sliding rod 34 is fixedly connected to the right side surface of the second through groove 312 near the rear end. The sliding rod 34 connects the turntable 35 and the guide groove 33, converting the rotation of the turntable 35 into sliding along the guide groove 33, achieving precise positioning.

[0034] Furthermore, the slide rod 34 slides on the inner walls of the two sets of guide grooves 33 respectively. The center of the right surface of the slide rod 34 and the left surface of the turntable 35 are connected by a pull rod 36. The pull rod 36 can be plugged and unplugged to fix or unlock the turntable 35, which is convenient for adjusting the position of the turntable 35. A positioning ring 39 is fixedly connected to the outer wall of the pull rod 36 near the left end. The positioning ring 39 limits the sliding range of the pull rod 36 and provides a force point for the spring 310. A positioning groove 311 is opened on the left side of the rear of the slide rod 34. The positioning groove 311 provides sliding space for the positioning ring 39 to ensure that the pull rod 36 moves smoothly. The positioning ring 39 is slidably connected to the positioning groove. The inner wall of 311 is elastically connected between the positioning ring 39 and the slide rod 34 by a spring 310. The elastic force of the spring 310 pushes the positioning ring 39, so that the left end of the pull rod 36 is always inserted into the socket 37, ensuring that the turntable 35 is stably fixed. The inner wall of the left side of the circular groove 38 is symmetrically provided with two sets of sockets 37 near the front and rear sides. The two sets of sockets 37 correspond to the top of the two sets of guide grooves 33 respectively. The left end of the pull rod 36 is inserted into the inner wall of the socket 37. The two sets of sockets 37 correspond to the opening position of the through groove 312 of the turntable 35 respectively, which facilitates the passage of the charging cable or its protection. The fixed turntable 35 can stably protect the cable and charging plug during charging.

[0035] Working principle: When in use, the U-shaped shielding frame 21 can surround the power socket 4 from the top, bottom, front, back and right sides, and together with the right side surface of the cabinet 1, it can achieve all-round wrapping and form the first layer of physical isolation protection. The inclined surface of the shielding plate 22 guides rainwater to slide to the right side to reduce rainwater retention. At the same time, the sealing gasket 23 is tightly attached to the right side surface of the cabinet 1 to prevent rainwater from seeping in through the gaps and enhance the sealing performance. Meanwhile, the sliding plate 31 is in the initial position, blocking the upper part of the through groove 32 to prevent rainwater from contacting the power socket 4.

[0036] When charging the ship is required, first loosen screw 25 and slide it out of the threaded hole. Then slide the cover frame 21 upward to open it, exposing the charging port 4. Next, fix the cover frame 21 by engaging screw 25 with another set of threaded holes. Then pull the lever 36 to pull its left end out of the socket 37, unlocking the turntable 35. Rotate the turntable 35 to slide the slide rod 34 along the inner wall of the guide groove 33 until the second through groove 312 is also downward. At this point, release the lever 36. Under the elastic force of spring 310, the left end of the lever 36 inserts into another set of sockets 37, fixing the turntable 35. Now connect the ship's charging plug to the charging port 4, and then unlock. The screw 25 moves the shielding frame 21 downward, and the charging cable passes through the inner walls of the first through slot 32 and the second through slot 312. After the shielding frame 21 moves downward and resets, the pull rod 36 is pulled and the slide rod 34 is rotated to reset, so that the first through slot 32 and the second through slot 312 cooperate to form a circular hole that completely wraps the charging cable. The semi-circular arc of the inner walls of the first through slot 32 and the second through slot 312 fits the outer wall of the cable, reducing friction and enhancing sealing. The turntable 35 and the shielding frame 21 can completely seal and protect the charging head and connection parts during charging, thereby blocking external debris and rainwater. The double protection ensures a safe and stable charging process.

[0037] After charging is complete, rotate the turntable 35 so that the through slot 312 faces downwards, and then move the shield 21 upwards to easily unplug the charging plug. At this time, reset the shield 21 and the slide plate 31 to restore the double protection of the non-charging state.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
