Description

Technical Field

[0001] The utility model belongs to the technical field of ship equipment, and particularly relates to a ship shore power charging interface structure. Background Art

[0002] Shore power refers to the equipment that provides power supply to moored ships through the port power system. When a ship is moored at a port, it needs to use electricity to maintain basic operations, such as lighting, air conditioning, cargo handling, and communication. If the ship uses its on-board generator to supply power, it will produce exhaust emissions, noise, and energy consumption. The shore power system provides a land power source (usually the power of the port power grid) to replace the ship's self-powered generating device, reducing fuel consumption and lowering carbon emissions and noise pollution during the ship's stay at the port. It is a green and environmentally friendly port operation method.

[0003] A ship shore power charging interface structure is a device used to connect the port shore power system and the ship's power system, usually installed at the interface between the ship and the port. Conventionally, such as a ship shore power charging interface structure disclosed in the patent application No. CN2023232561292, which includes a shore power box and a charging cable. A protection box is arranged on one side inside the shore power box, and the protection box is rotatably connected to the shore power box through a movable hinge. A charging base is arranged inside the shore power box; a clamping auxiliary component is arranged on one side of the charging base, and the clamping auxiliary component is used for assisting the installation and clamping fixation of the charging cable; a protection component is arranged on the charging base and the protection box, and the protection component is used to provide protection for the uncharged interface to prevent accidental damage; an induction component is arranged on the charging base, and the induction component is used to sense and identify whether the position of the charging cable is normal.

[0004] Since the use environment of the ship shore power charging interface is a humid environment, water accumulation or water vapor is likely to occur on the protection box in this technical solution. During the process of opening the protection box, the accumulated water will flow obliquely downward along the upper end surface of the protection box. Since the connection between the shore power box and the protection box is a hinge rotational connection, there is a certain gap during the opening process, and the accumulated water may flow into the shore power box through this gap, making the inside of the shore power box humid, accelerating the aging of electrical components, being unfavorable for ensuring the service life of the shore power box, and at the same time, it may also cause the risk of short circuit or electric shock to personnel, and the safety needs to be improved.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] Embodiment 1: As Figures 1 to 5 shown, a ship shore power charging interface structure includes a shore power box 1, a charging cable 2 and a protective cover 3. A charging seat 11 is arranged on the front side of the shore power box 1. The upper end of the rear side of the protective cover 3 is rotatably connected to the upper end of the front side of the shore power box 1 through a movable hinge 4. One end of the charging cable 2 is provided with a plug 21 for plugging and mating with the charging seat 11. An elastic water baffle 5 is arranged on the upper end surface of the protective cover 3. The rear side of the water baffle 5 is placed on the upper end surface of the shore power box 1, and the water baffle 5 covers the movable hinge 4. Among them, the water baffle 5 is made of rubber material.

[0028] In this embodiment, a groove 51 adapted to the movable hinge 4 is arranged on the lower end surface of the water baffle 5, and the movable hinge 4 is located in the groove 51, which helps to improve the tightness of the fit and further improve the waterproof effect.

[0029] During the opening process of the protective cover 3, the water baffle 5 can always keep in contact with the upper end surface of the shore power box 1, and the water baffle 5 is located above the gap between the upper end surface of the shore power box 1 and the upper end surface of the protective cover 3. The accumulated water on the upper end surface of the protective cover 3 can only flow to the upper end surface of the shore power box 1 along the water baffle 5 and cannot flow into the shore power box 1 through this gap.

[0030] Embodiment 2: As Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the rest of the parts are the same as those in the first embodiment, except that a mounting seat 31 is fixedly provided on the upper end surface of the protection cover 3 , and the front side of the water retaining strip 5 is detachably connected to the mounting seat 31 .

[0031] In this embodiment, a slot 311 is provided on the rear side surface of the mounting seat 31, and a screw hole 312 and a bolt 313 are provided on the upper end surface of the mounting seat 31. The front side of the water retaining strip 5 is inserted into the slot 311, and the bolt 313 passes through the screw hole 312 and is pressed on the water retaining strip 5. The structure is simple, and it is convenient to disassemble and replace the water retaining strip 5, which is convenient for later maintenance.

[0032] In this embodiment, a support seat 12 is fixedly provided on the upper end surface of the shore power box 1, and the upper end of the support seat 12 extends forward to form a convex strip 13, and the convex strip 13 is embedded with a first magnet (not shown in the figure), and the mounting seat 31 is embedded with a second magnet (not shown in the figure). When the protective cover 3 is flipped upward, the mounting seat 31 abuts against the convex strip 13, and at this time, the first magnet and the second magnet are adsorbed and matched. The conventional structural design requires that the protective cover 3 be flipped to the upper end surface of the shore power box 1, and the flipping angle is 180°. After the water retaining bar 5 is set, the present technical solution cannot be flipped 180°, and too large a flipping angle may easily cause the water retaining bar 5 to tear, which is not conducive to the long-term use of the water retaining bar 5. Therefore, by setting a support seat 12, a convex strip 13, a first magnet and a second magnet, when the protective cover 3 is flipped upward by about 90°, the first magnet and the second magnet are adsorbed and cooperated to keep the protective cover 3 in an open state. The user plugs the plug 21 into the charging seat 11 and then flips the protective cover 3 downward. The operation is relatively simple, and the water retaining bar 5 will not be excessively bent, which is beneficial to extending the service life of the water retaining bar 5.

[0033] Embodiment 3: Figure 1 , Figure 2 and Figure 5 As shown, the rest of the parts are the same as those of the first embodiment, except that a plurality of drainage grooves 14 distributed along the front-to-back direction are arranged on the upper end surface of the shore power box 1, and the left and right sides of the drainage grooves 14 penetrate the left and right sides of the shore power box 1, and the water retaining bar 5 covers part of the drainage grooves 14, and the accumulated water on the upper end surface of the shore power box 1 can flow into the drainage grooves 14 and be discharged. In the process of opening the protective cover 3, the rear side of the water retaining bar 5 will move backward, and the accumulated water on the upper end surface of the protective cover 3 will flow along the water retaining bar 5 to the upper end surface of the shore power box 1 and flow into the drainage grooves 14 located behind the water retaining bar 5 for discharge; when closing the protective cover 3, if there is a little accumulated water on the upper end surface of the shore power box 1, and the accumulated water is located below the water retaining bar 5, the rear side of the water retaining bar 5 will move forward and scrape the accumulated water forward into the drainage grooves 14 to prevent the accumulated water from possibly seeping into the shore power box 1, and the reliability is good.

[0034] Furthermore, the rear side surface of the drainage groove 14 is an inclined surface that slopes from the rear to the front and downward, so as to prevent the rear side of the water retaining bar 5 from having a hard collision with the side surface of the drainage groove 14 during the backward movement.

[0035] In this embodiment, a base 15 extending forward is provided on the lower end surface of the shore power box 1, and a protective cover 3 covers the front side of the shore power box 1 and the upper end surface of the base 15. A through groove 32 is provided at the lower end of the protective cover 3, and two rubber sheets 33 symmetrically distributed on the inner wall of the through groove 32 are provided. One end of the charging cable 2 passes through the through groove 32 and extends into the protective cover 3 to be connected to the charging seat 11.

[0036] In this embodiment, a fixing seat 6 is provided on the base 15, and the upper end surface of the fixing seat 6 is recessed downward to form a first arc-shaped groove 61.
