Description

Technical Field

[0001] The utility model relates to the technical field of electricity boxes, in particular to a shore power box. Background Art

[0002] A shore power box (pile), also known as a shore power connection box or shore power conversion box, is a key device used to connect the shore power supply to the ship's power system when the ship is docked. Usually installed at a dock or on a ship, the shore power box converts shore power into power specifications suitable for the ship, thereby replacing the ship's own power generation equipment, reducing fuel consumption and emissions while the ship is at anchor, and achieving the goals of energy conservation, emission reduction, and environmental protection. The shore power box usually contains power conversion equipment, control and protection devices, and interfaces for connecting to the shore power grid and the ship's power system.

[0003] Since the shore power box is installed outdoors at the front of the port terminal, the humidity and salinity at the seaside are high, and it is prone to problems such as waves and heavy rain. These moisture can easily erode the interior of the shore power box through the ventilation holes. The salt and alkali can easily corrode the surface of the shore power box, causing damage to the components and the surface of the box. As a result, the shore power box has low safety, a short service life, and requires frequent maintenance.

[0004] Therefore, it is necessary to invent a shore power box to solve the above problems. Utility Model Content

Three groups of second shields are hinged on the upper right side of the front surface of the electric box body, and instrument panels are provided inside the second shields. Multiple groups of indicator lights are fixedly connected to the lower right side of the front surface of the electric box body.

[0016] By adopting the above technical solution, the first shield and the second shield are both made of transparent materials and are used to protect the control buttons and the instrument panel. The control buttons are used to control the electric box body, and the instrument panel is used to observe the power consumption of the electric box body.

[0017] Optionally, two sets of adapters are fixedly connected to the right side surface of the electrical box body, and the adapters are plugged into the inside of the plug holes.

[0032] During the installation process, the two sets of movable sealing plates 18 on the left side of the protective box 1 are opened, and the electric box body 3 is pushed from the left side of the protective box 1 to the inside of the protective box 1, and then the two sets of movable sealing plates 18 are closed to seal the left side of the protective box 1. The protective box 1 protects the electric box body 3 to prevent rainwater and seawater from directly splashing onto the surface of the electric box body 3, thereby preventing rainwater, seawater and salinity from eroding the surface and interior of the electric box body 3, effectively improving the safety and service life of the equipment, reducing the number of equipment maintenance times, and improving the equipment operation efficiency. At the same time, the raised ventilation box 2 is coordinated with the inverted protective cover 23 to make the first exhaust vent 21 and the second exhaust vent 24 staggered, while effectively dissipating heat for the electric box body 3, preventing rainwater and seawater from entering the interior of the protective box 1. At the same time, the dehumidifier 22 dehumidifies the air entering the interior of the protective box 1, so that the interior of the protective box 1 is in a dry state, avoiding the erosion of the interior of the electric box body 3 by moisture in the air, further improving the safety and service life of the equipment.

[0033] See Figure 4Two groups of first shields 31 are hinged on the left side of the front surface of the electric box body 3, and control buttons are arranged inside the first shields 31. Three groups of second shields 32 are hinged on the upper right side of the front surface of the electric box body 3, and an instrument panel is arranged inside the second shield 32. Multiple groups of indicator lights 33 are fixedly connected to the lower right side of the front surface of the electric box body 3, and two groups of adapters 35 are fixedly connected to the right side surface of the electric box body 3. The adapter 35 is plugged into the inside of the socket 13. Two groups of third support frames 34 are fixedly connected to the lower surface of the electric box body 3. The third support frame 34 is mounted on the upper surface of the first support frame 16, and the bottom of the electric box body 3 is mounted on the upper side of the second support frame 17.

[0034] Specifically, the control button inside the first protective cover 31 is used to control the opening and closing of the entire electrical box body 3. The instrument panel inside the second protective cover 32 is a color touch screen, which can display the power usage of the three shore power sockets of the electrical box in real time, and can locally control the power supply off. During the use of the electrical box body 3, the sealing cover 14 on the right is opened, and then the connector on the ship is inserted into the adapter 35, and then the transparent sealing plate 12 is opened, and then the second protective cover 32 is opened. The electrical box body 3 is controlled through the touch screen, and then the transparent sealing plate 12 is closed. At this time, the status of the instrument panel and the status of the indicator light 33 can be observed through the transparent sealing plate 12 and the second protective cover 32, and the power supply status can be observed.

[0035] In addition, a smart meter can be installed inside the electrical box body 3. The smart meter can transmit real-time electricity data to the ship E-travel platform in real time, directly collect real-time data through the network connection module and push it to the owner's platform, and transmit the smart meter data to the owner's power monitoring background through optical fiber, thereby realizing real-time monitoring of the electricity consumption of the electrical box body 3. At the same time, the power supply and power outage of the socket can be controlled by scanning the corresponding QR code with a mobile phone, which effectively improves the intelligence of the electrical box body 3 and can remotely supply and cut off power, avoids frequent opening of the transparent sealing plate 12, reduces external moisture from entering the interior of the protective box body 1, especially in rainy weather, avoids rainwater from entering the interior of the protective box 1, and further improves the protection function of the electrical box body 3.

[0036] The working principle of the utility model is as follows: the protective box body 1 is used to protect the electric box body 3 to prevent rain, seawater and saline-alkali from eroding the electric box body 3; at the same time, the ventilation box 2 cooperates with the inverted protective cover 23 to effectively dissipate heat for the electric box body 3 while preventing rainwater and seawater from entering the interior of the protective box body 1; and the dehumidifier 22 is used to dehumidify the air entering the interior of the protective box body 1, so that the interior of the protective box body 1 is in a dry state, which effectively improves the safety and service life of the equipment, reduces the number of equipment maintenance times, and improves the equipment operation efficiency.
