Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a ship and its external power supply system. Background Technology

[0002] As the installed capacity of offshore wind power increases, the requirements for the navigation ecology and technology of wind power operation and maintenance vessels are constantly rising, making the functionality of these vessels and the protection of personnel's electrical safety increasingly important. When transporting personnel and equipment to wind turbine piles, offshore wind power operation and maintenance vessels often require additional power supply boxes for maintenance work due to the needs of wind farm construction. In such cases, the external power supply system on the vessel can be used as a supplement. Currently, the external power supply system on existing wind power operation and maintenance vessels typically stores power cables manually on the deck or in open rooms. Due to the influence of the work area and the required cable diameter, the length and weight of the cables are limited, gradually increasing the workload of the personnel, especially during cable retraction and coiling. This is inconvenient, time-consuming, and labor-intensive, and also poses certain safety hazards to personnel using external power supply. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4 This utility model provides an external power supply system for a ship, including a power supply box 100, a reel 200, a waterproof protection box 300, and a cable 400. The power supply box 100 is installed in the ship's interior, the reel 200 is rotatably installed in the ship's interior, the waterproof protection box 300 is installed on the deck, and the cable 400 is wound on the reel 200. The two ends of the cable 400 are respectively provided with a first plug 410 and a second plug 420. The first plug 410 can be plugged into the power supply box 100, and the second plug 420 extends from the deck into the waterproof protection box 300. The waterproof protection box 300 includes a box body 310 and a box cover 320, and the box cover 320 can be opened to allow the second plug 420 to be taken out.

[0022] When not in use, cable 400 is wound on drum 200, located inside the ship's interior. This protects the cable from seawater immersion and sun exposure, extending its lifespan and maintaining a neat deck layout. The second plug 420 of cable 400 is located inside a waterproof protective box 300, which protects it from seawater corrosion, extending its lifespan and preventing accidental leakage, thus improving electrical safety. When cable 400 needs to be used, operators simply open the box cover 320, remove the second plug 420, and easily pull it to rotate the drum 200 to release the cable 400. The second plug 420 is then connected to a wind turbine for power supply. After use, the drum 200 is rotated to retract the cable 400, the second plug 420 is returned to the waterproof protective box 300, and the box cover 320 is closed. Compared to existing technologies, this significantly reduces the workload for operators.

[0023] Furthermore, the waterproof protective box 300 is made of aluminum sheet, which is lightweight and easy to weld and form, making it easy to weld onto the deck. A through-hole is provided on the deck corresponding to the position of the waterproof protective box 300, allowing the second plug 420 to extend from the ship's interior through the through-hole into the waterproof protective box 300. The box body 310 of the waterproof protective box 300 has an opening, and the lid 320 can rotate to close the opening. A waterproof ring is provided around the outer periphery of the opening. When the lid 320 rotates to close the opening, the waterproof ring effectively improves the waterproof performance of the waterproof protective box 300. Further, refer to... Figure 2 A pulley 600 is rotatably connected inside the waterproof protective box 300. The pulley 600 is positioned near the opening, and the cable 400 is wound around the groove of the pulley 600. This effectively protects the outer insulation layer of the cable 400, preventing wear during pull-out. Simultaneously, the pulley 600 allows for easy pulling of the cable 400. Further, refer to... Figure 2 A hook 700 is provided on the second plug 420 or the cable 400 near the second plug 420, which facilitates the use of a ship's crane to transport the cable 400 and the second plug 420 to a greater distance via a lifting rope and the hook 700, reducing the workload of the operators. Furthermore, a locking device is provided on the second plug 420 or the cable 400 near the second plug 420 to secure the second plug 420 to the wind turbine plug. This prevents the plugs from detaching and causing a leakage hazard when the ship is rocked by wind and waves. Furthermore, the locking device can be a snap-fit ​​or similar structure.

[0024] Furthermore, this external power supply system also includes a mounting bracket 500, which is installed on the grating plate inside the ship's interior. The drum 200 is rotatably mounted on the mounting bracket 500. While meeting the requirements for weight and structural strength of the drum 200, it can be made of aluminum profiles, which are lightweight, easy to weld, and simple to construct. Further, refer to... Figure 4 The fixing frame 500 includes a connecting part 510 and support parts 520 located at both ends of the connecting part 510. The connecting part 510 is fixedly connected to the hull grating plate. The support parts 520 are trapezoidal in shape, wider at the bottom than the top, to improve support stability. The two ends of the drum 200 are rotatably connected to the two support parts 520. Furthermore, while meeting the weight and structural strength requirements of the cable 400, the drum 200 is made of aluminum tubing, which is lightweight, easy to weld, and simple to install. Further, refer to... Figure 3 The drum 200 includes a rotating shaft 210 and a winding frame 220 and a stop frame 230 fixedly connected to the shaft. The stop frame 230 is located at both ends of the winding frame 220, and the outer diameter of the stop frame 230 is larger than the outer diameter of the winding frame 220. Bearing seats 530 are mounted on the support portion 520 of the fixed frame 500. Both ends of the rotating shaft 210 are connected to the bearing seats 530. The rotating shaft 210 can be driven by a motor or other drive components, or it can be manually rotated by a handle. The cable 400 is wound on the winding frame 220, and the stop frame 230 can stop the cable 400 to prevent it from falling off from both ends of the winding frame 220. Furthermore, the winding frame 220 includes multiple crossbars 221, which are distributed circumferentially along the rotating shaft 210. Two stop frames 230 are fixedly connected to both ends of the crossbars 221. Each crossbar 221 is connected to a reinforcing rib 222, which can reduce the weight of the winding frame 220 while ensuring the structural strength of the winding frame 220.
