Technical Field

[0001] The utility model relates to the technical field of distribution boards, in particular to a main distribution board for ships. Background Art

[0002] With the development of the maritime transportation industry, the safety and reliability of shipboard electrical equipment have become crucial factors. As the core of a ship's power system, the ship's main switchboard is responsible for receiving, distributing, and protecting power. However, due to the unique operating environment of ships, such as seawater corrosion, high humidity, and hull vibration, the main switchboard faces numerous challenges. Preventing ground water from seeping into the switchboard is a key concern for designers.

[0003] Most marine main switchboards currently on the market are designed with waterproofing and moisture-proofing in mind, employing methods such as waterproof coatings and sealing materials to enhance their corrosion resistance. However, when a ship encounters severe weather or sea conditions, water may accumulate within the hull. This is particularly true in lower deck areas or when equipment is installed at a low point. Traditional waterproofing measures are unable to completely prevent moisture from entering the switchboard from the bottom, thus affecting the safe operation of electrical equipment.

[0004] In view of the above problems, it is particularly important to design a structure that can enhance the waterproof performance of the bottom of the main distribution board. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 7As shown, the present invention discloses a marine main switchboard, comprising a functional panel mechanism comprising a plurality of load panels 1, a combination starter panel 2, a generator panel 3, and an isolation and paralleling panel 4. It should be noted that these panels may be increased, decreased, or combined depending on the specific needs of the vessel. The design requires customization of the appropriate configuration based on the actual use and scale of the vessel to ensure that all necessary functions are properly managed and controlled. In the present invention, a bottom side protection mechanism is provided on the lower side of the functional screen mechanism, which includes a left frame assembly 5, a right frame assembly 6 and several middle frame assemblies 14. The middle frame assembly 14 is detachably connected between the left frame assembly 5 and the right frame assembly 6. The left frame assembly 5, the middle frame assembly 14 and the right frame assembly 6 are combined to surround the bottom side of the functional screen mechanism, thereby preventing accumulated water from penetrating from the bottom of the main distribution board and improving the waterproof performance of the bottom of the main distribution board. In addition, the middle frame assembly 14 can be specifically set according to the number of load panels 1, combined starting panels 2, generator panels 3 and isolation and paralleling panels 4, because the specific needs of different ships may increase, decrease or merge, and the functional screen mechanism composed of different numbers of load panels 1, combined starting panels 2, generator panels 3 and isolation and paralleling panels 4 has a different footprint. The present invention can set the number of middle frame assemblies 14 according to the actual size of the functional screen mechanism, so that the bottom side of the functional screen mechanism can be effectively and reasonably surrounded without wasting space.
