Description

Technical Field

[0001] This utility model relates to the technical field of dock shore power cable box shell structure design, specifically to an outdoor cable box structure for a dock shore power system. Background Technology

[0002] Ships typically use fuel-fired power, a method that is affected by factors such as the quality and scale of the ship's equipment, resulting in low fuel utilization, significant losses, and substantial energy waste. With the increasing maturity of new energy sources, shore power technology for ships is also developing in the maritime sector, offering better ways to reduce environmental pollution and save on power costs during port calls. The electrical system of shore power should be as consistent as possible with the ship's electrical system. Most ships primarily use low-voltage power transmission, with a small portion using high-voltage. A single shore power supply at a dock is usually either high-voltage or low-voltage and cannot simultaneously supply both. With the development of cable-based power distribution networks, when small, independent loads are concentrated, cable branch boxes can be used to connect multiple cable branches. These branch boxes cannot directly operate on each branch; they are only used as cable branches. The main function of the cable branch box is to split or transfer cables.

[0003] Cable branch boxes are mostly used in outdoor locations for cable distribution and connection. Outdoor cable branch boxes also serve as cable transfer points. On a relatively long line, if the cable length cannot meet the line requirements, cable joints or cable transfer boxes must be used. Usually, cable intermediate joints are used for short distances, but for longer lines, based on experience, on cable lines over 1000m, if there are multiple intermediate joints in the cable, cable branch boxes will be considered for transfer to ensure safety. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide an outdoor cable box structure for a dock shore power system, which is equipped with an external hook chain to restrict the opening and closing of the box cover, realize multi-angle opening and closing adjustment, and facilitate tapping, wiring or maintenance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an outdoor cable box structure for a dock shore power system, comprising a main box body and a box cover that opens and closes relative to the main box body.

The cover 2 is provided with a locking structure that matches the main box body 1. The upper end of the cover 2 is provided with a hinged hinge 8 that is hinged to the main box body 1. The outer side of the cover 2 is also provided with a hook chain 3 and a hook 4. The main box body 1 is also provided with a hanging ring 5. The hook chain 3 includes a ring chain 31 and a self-locking hook 32. The self-locking hook 32 is provided with a return spring for locking the self-locking hook 32.

[0017] As a further feature of the above scheme, the box cover 2 is provided with two sets of mirror symmetrical boxes, which can be independently flipped and opened and closed, and the hook chain 3 can be used to limit the opening and closing angle of the box cover 2 by switching between the hook 4 and the hanging ring 5.

[0018] As a further provision of the above solution, the locking structure includes a locking groove 11 provided on the main body 1 and a locking ring 12 provided in the locking groove 11. The cover 2 is provided with a locking plate 21 opposite to the locking groove 11, and the locking plate 21 is provided with a locking groove 22 opposite to the locking ring 12.

[0019] As a further provision of the above scheme, a rainwater trough 13 is provided on the main body 1 at the hinge point relative to the cover 2, and a rainwater baffle 14 is also provided on the main body 1. A rainwater eave 23 is provided on the cover 2, and when closed, it is fastened to the outside of the rainwater trough 13 and the rainwater baffle 14. A main heat dissipation vent 18 is also provided on the main body 1, and a sub-heat dissipation vent 24 is provided on the inner side of the cover 2 relative to the rainwater eave 23.
