[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-4 As shown, a shore power interface adapter box in this embodiment includes an adapter box body 1. A shore power socket 4 is installed in the middle of one side wall of the adapter box body 1. The shore power socket 4 is mainly connected to the power supply plug on the shore power equipment. An adapter socket 6 is installed on the side wall of the adapter box body 1 opposite to the shore power socket 4. The adapter socket 6 is mainly connected to the power supply plug on the ship. An anti-loosening component 3 is installed on the adapter box body 1 at the shore power socket 4 and each adapter socket 6. The anti-loosening component 3 includes a rotating head 301, a sliding groove 302, and a bidirectional threaded rod 303. The mounting frame 304, clamping plate 305, wing nut 306, stud 307, and slide groove 308 are used to install power plugs into the shore power socket 4 and the adapter socket 6 respectively. Under the action of the rotating head 301, the bidirectional threaded rod 303 rotates, which can cause the two clamping plates 305 to move closer to the corresponding power plugs under the action of thread transmission. After the clamping plates 305 clamp the power plugs, the wing nut 306 is tightened, which can realize the clamping plate 305's limit after clamping, thereby ensuring the reliable anti-loosening of the power plugs at the shore power socket 4 and the adapter socket 6.

[0025] like Figures 1-4 As shown in this embodiment, a lifting ring 2 is welded to each of the four corners of the top of the adapter box body 1. The adapter box body 1 can be hoisted and used as needed with the help of the lifting ring 2. The opening of the adapter box body 1 is also connected to a door 5 by a hinge. Opening the door 5 allows for convenient inspection and maintenance of the interior of the adapter box body 1. The adapter box body 1 contains a phase sequence meter and a power supply wire with an air switch for connecting the shore power socket 4 and the adapter socket 6. The power supply wire enables the transmission of electrical energy between the shore power socket 4 and the adapter socket 6.

[0026] like Figures 1-4As shown, in this embodiment, the mounting frame 304 is bolted to the outer wall of the adapter box body 1. There are two slide grooves 302, which are symmetrically arranged on the upper and lower sides of the mounting frame 304. The slide grooves 302 are mainly used to guide the sliding of the clamping plate 305, and at the same time, they can ensure that the bidirectional threaded rod 303 has sufficient installation space. The bidirectional threaded rod 303 is rotatably installed in the slide groove 302 on the upper side of the mounting frame 304. Two arc-shaped clamping plates 305 are symmetrically installed on the bidirectional threaded rod 303. The rotating head 301 is installed on the exposed end of the bidirectional threaded rod 303. The clamping plate 305 has a reserved slide table at the part that mates with the slide groove 302. With the help of the rotating head 301 The bidirectional threaded rod 303 can be easily rotated and adjusted. After being clamped by the clamping plate 305, it can be initially limited by the threads on the bidirectional threaded rod 303. The second slide groove 308 is opened on the lower part of one side wall of the mounting frame 304. The stud 307 is welded to the side wall of the slide table at the lower part of the clamping plate 305, and the stud 307 passes through the second slide groove 308. The second slide groove 308 is mainly used to provide space for the stud 307 to slide. The wing nut 306 is threadedly connected to the stud 307. The wing nut 306 is located on the outside of the mounting frame 304. When the clamping plate 305 clamps the external power plug, the wing nut 306 is tightened to fit against the side wall of the mounting frame 304, which can provide secondary limitation for the clamping plate 305.

[0027] The specific implementation process of this embodiment is as follows: When using the adapter box body 1 to supply power to the ship, first install the adapter box body 1 at the designated power supply position, then connect the shore power socket 4 on the adapter box body 1 to the power supply plug on the shore power equipment, and connect the adapter socket 6 to the power supply plug on the ship. Then, under the action of the rotating head 301, the bidirectional threaded rod 303 is rotated so that the two clamping plates 305 move closer to the corresponding power supply plugs under the action of thread transmission. After the clamping plates 305 clamp the power supply plugs, tighten the wing nut 306 to achieve a second limiting of the clamping plates 305 after clamping. This ensures reliable anti-loosening of the power plugs at shore power socket 4 and adapter socket 6, facilitating reliable connection between the ship and shore power equipment using the adapter box body 1, and meeting the ship's power supply needs. Since the anti-loosening component 3 clamps and limits the wiring plugs at shore power socket 4 and adapter socket 6 during use, it effectively reduces the risk of loosening of the wiring plugs at shore power socket 4 and adapter socket 6 due to sea breeze in the external environment, avoids the drawback of poor contact between shore power equipment and the ship, and makes the shore power interface adapter box more stable in use.
