Description

Technical Field

[0001] This utility model relates to the technical field of shore power equipment, specifically to a shore power box. Background Technology

[0002] Shore power equipment is a system that supplies power from the shore to the ship while it is docked in port. It utilizes shore power to replace diesel generators, directly supplying power to yachts, passenger ships, cargo ships, and container ships. Its main function is to ensure that ships continue to operate their production, living, and auxiliary equipment while in port, reducing pollution and noise pollution while docked. It also saves fuel costs and improves operational efficiency. A shore power distribution box (hereinafter referred to as a shore power box) is a dedicated power supply device installed at port terminals. It typically uses a three-phase AC power distribution system to provide a fast and safe standard shore power interface for docked ships, enabling branch-cable power supply, data acquisition, billing, and settlement.

[0003] To facilitate convenient charging of yachts at marinas, shore power boxes are now being installed, similar to car charging stations. Currently, these boxes are primarily enclosed structures with doors, and yachts connect to them via cables. Existing shore power boxes typically include protection and monitoring devices for the shore power supply system. The existing shore power supply system includes input interfaces, output plugs, and transformers / frequency converters, primarily connecting high-voltage / low-voltage AC power from shore to the ship's power distribution system via cables to meet the ship's lighting, cooling, and communication needs while it is moored. Existing protection devices typically include circuit breakers, grounding systems, various instrument panels and indicator lights, monitoring parameters such as voltage, current, and power in real time. Some are equipped with intelligent remote control functions to ensure safety. However, existing shore power boxes have many internal components, making assembly cumbersome and causing interference during wiring, which hinders assembly by workers. Furthermore, existing shore power boxes typically lack lighting, making wiring at night when the ship is moored particularly difficult. Utility Model Content

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0024] Depend on Figure 1 Combination Figure 2 As shown, a shore power box includes a box body 1, the box body 1 having a door 2, and further includes:

[0025] The shore power transmission system is located inside the enclosure 1; the shore power transmission system includes a transformer 3;

[0026] Protection system 4 is located inside enclosure 1; the protection system 4 includes circuit breaker 41 and indicator assembly 42;

[0027] Cable outlet compartment 5 is located on the side of housing 1, and cable outlet compartment 5 includes a charging socket;

[0028] A mounting bracket 6 is installed inside the enclosure 1 and is vertically positioned. Multiple mounting plates 7 are mounted on the mounting bracket 6, and these plates are detachably connected to the bracket. The transformer 3 and circuit breaker 41 are mounted on different mounting plates 7. The advantages of this invention are that the mounting bracket and mounting plates are detachable from the bracket, allowing components inside the enclosure to be installed on the mounting plates before being placed inside. This also allows for adjustment of the spatial position of components inside the enclosure, facilitating wiring and heat dissipation. This invention also features a simple structure, convenient assembly, and long service life.

[0029] The mounting bracket 6 has multiple mounting holes 61, which are elongated. The mounting plate 7 is connected to the mounting bracket 6 through the mounting holes 61. This allows different mounting plates to be installed in the mounting holes, resulting in a simple structure and convenient and reliable fixing. The different mounting holes also allow for vertical adjustment of the spacing between different components. The elongated mounting holes also allow for fine-tuning of the spacing between different components in the vertical direction, facilitating assembly, wiring, and heat dissipation.

[0030] The mounting plates 7 consist of multiple pieces, each vertically mounted to the mounting bracket 6. Each mounting plate 7 has a connection hole 71 and a heat dissipation hole 72. Specifically, the mounting plates 7 are elongated and have a C-shaped cross-section, with the opening of the C-shaped mounting plate 7 facing away from the door 2. The connection holes facilitate component assembly, allowing components to be assembled outside the box before overall (modular) assembly, simplifying the internal assembly process. The heat dissipation holes improve the product's heat dissipation performance. The C-shaped mounting plates increase product strength, preventing deformation and extending the product's service life.

[0031] The inner wall of the enclosure door 2 is provided with a cable guide bracket 21, which cooperates with the inner wall of the enclosure door 2 to form a cable passage hole 22. This structure facilitates wiring inside the enclosure and avoids mutual interference between wire harnesses, thus preventing any impact on product performance.

[0032] This utility model also includes a water-blocking component 11, disposed on the upper part of the box body 1; the box door 2 has a first closed position and a second open position; the water-blocking component 11 is disposed above the box door 2 when the box door is in the first position. The water-blocking component can block the connection between the box door and the upper part of the box body, preventing rainwater from flowing into the box door along the upper edge of the box body, thus improving the product safety performance.

[0033] The enclosure door 2 is provided with a vent 23, which corresponds to the transformer 3; the bottom of the enclosure 1 is provided with a heat dissipation slot 12. This structure allows for gas circulation, improves the product's heat dissipation performance, and increases the product's lifespan. The vents are typically small holes.

[0034] The container 1 is equipped with a hook 13 and a lighting component 14. The lighting component 14 is located on the upper part of the container 1, and the hook 13 is located on the top of the container 1. The hook facilitates handling and has a simple structure. Specifically, the lighting component 14 includes a lamp and a lighting cover, the lighting cover being integrally molded from a light-transmitting material. Typically, the lighting cover can be integrally molded from a light-transmitting acrylic sheet. This allows the product to emit light, facilitating nighttime ship berthing and use by personnel.

[0035] The indicator component 42 includes a power supply indicator light 421 and a closing indicator light 422, which are located above the outgoing line compartment 5. This structure facilitates observation by personnel. The enclosure typically also includes a voltmeter, wattmeter, phase sequence meter, and phase sequence selection switch. For example, the fuses in the protection system can be connected to the shore power supply indicator light, closing indicator light, wattmeter, and phase sequence meter; the circuit breakers in the protection system can be connected to the transformer. These can all be implemented using existing technologies and will not be elaborated upon here.
