Description

Technical Field

[0001] This utility model belongs to the field of cable equipment technology, specifically relating to an auxiliary support device for shore power cable deployment and take-up. Background Technology

[0002] Shore power systems are a key technology for the green transformation of modern ports and shipping industries. Their core function is to supply power to ships when they are docked, replacing auxiliary engine power generation and effectively reducing emissions of harmful substances such as sulfur oxides, nitrogen oxides, and particulate matter. This plays a crucial role in improving air quality and reducing noise pollution in port areas. Shore power cables, as the "lifeline" connecting ships to shore power sources, are directly affected by the efficiency and safety of their deployment and retrieval operations. During cable deployment and retrieval, due to the cable's weight, length, and the often varying slopes or angles along the path, a lack of effective support and guidance can easily lead to friction between the cable and the ground or ship's side, accelerating sheath wear and even causing problems such as cable kinking and jamming. This not only affects cable lifespan but may also pose operational safety hazards. Therefore, specialized auxiliary support devices are typically required during shore power cable laying and retrieval operations to support and guide the cable, reducing resistance, preventing wear, and adapting to different deployment and retrieval conditions.

[0003] During the process of connecting ships to shore power, shore power cables are usually quite heavy (a single cable can weigh hundreds of kilograms) and need to be frequently deployed and retracted. Traditional operating methods have the following problems: 1. Severe cable wear: When cables are dragged directly on the ground during winding and unwinding, the friction between the outer sheath and the ground can easily damage the insulation layer, increasing the risk of leakage. 2. High labor costs: It is time-consuming and labor-intensive for multiple people to work together to lift the cable, especially when the ship's altitude changes (such as due to tides), and the support points need to be adjusted repeatedly; 3. Insufficient adaptability: Existing fixed supports cannot adapt to changes in the height difference between ships and docks, which can easily lead to excessive tension or slack in cables.

[0004] While some solutions employ guide rollers or electrically operated take-up and take-down devices, these suffer from complex structures and high modification costs. Therefore, a low-cost, easily implemented mechanical auxiliary device is urgently needed to address these pain points.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary support device for the deployment and retraction of shore power cables to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A shore power cable retraction and deployment auxiliary support device includes a base plate.

[0018] See attached document Figure 1-7 A shore power cable retraction and deployment auxiliary support device includes a base plate 11. Two symmetrically distributed outer frames 5 are fixed on the top side of the base plate 11. An inner frame 3 is arranged between the two outer frames 5. A shaft 6, rotatably connected to the outer frames 5, is fixed to one end of the inner frame 3. A locking assembly 1 is arranged between the inner frame 3 and the outer frames 5. A support 7 is fixed to the top of the inner frame 3. A rubber roller 8 is rotatably connected inside the support 7. A stabilizing assembly 2 is arranged at the bottom of the base plate 11. During use, the cable is supported by the rotation of the rubber roller 8, reducing the friction when the cable moves. The rubber roller 8 is made of rubber material, which ensures sufficient friction to prevent cable slippage and avoids wear on the cable sheath. The shaft provides stable support. The inner frame 3 and rubber roller 8 are supported to ensure smooth rotation of the roller. Operators can adjust the tilt angle of the inner frame 3 and rubber roller 8 by rotating them according to the actual cable routing requirements. The inner frame 3 is then locked after adjustment by the locking component 1, which allows for easy adjustment of the tilt angle of the rubber roller 8. This allows the adjustment to adapt to different cable retraction angles. The operation is simple and requires no special tools. It can cope with changes in ship height caused by tidal changes, making it highly adaptable. The overall structure is relatively simple and practical. The stabilization component 2 combines convenient movement and stable placement of the entire device into one unit, facilitating relocation and use, and effectively improving overall practicality.

[0019] Further as Figure 2 and Figure 3 As shown, it is worth noting that the locking assembly 1 includes a protruding post 102 fixed to the side of the inner frame 3. An arc-shaped groove 101 that slides and adapts to the protruding post 102 is provided on the side of the outer frame 5. The arc-shaped groove 101 is arranged concentrically with the shaft 6. A threaded hole 105 is provided in the arc-shaped groove 101, and a locking bolt 103 is threadedly connected in the threaded hole 105. When the inner frame 3 is rotated and adjusted, the inner frame 3 drives the protruding post 102 to slide in the arc-shaped groove 101. By tightening the locking bolt 103, the inner frame 3 is clamped and fixed, thereby achieving stable locking of the inclination angle of the inner frame 3 and the rubber roller 8.

[0020] Further as Figure 3As shown, it is worth noting that a rubber pad 104 is provided at the nut end of the locking bolt 103; in actual operation, the rubber pad 104 effectively increases the friction between the nut of the locking bolt 103 and the side of the outer frame 5, further improving the locking stability of the inner frame 3.

[0021] Further as Figure 2 , Figure 6 and Figure 7 As shown, it is worth noting that multiple symmetrically distributed support legs 9 are fixed to the bottom end of the base plate 11, and casters 10 are installed at the bottom ends of the support legs 9. The stabilization assembly 2 includes a base plate 201 fixed to the bottom end of the base plate 11. The base plate 201 has an inner cavity 206, and multiple liquid cylinders 202 are arranged equidistantly within the inner cavity 206. The liquid cylinders 202 are connected to the inner cavity 206. A connecting rod 204 is inserted inside the liquid cylinder 202. A support plate 205 is fixed to the bottom end of the connecting rod 204, and a piston plate 203 that fits tightly against the inner wall of the liquid cylinder 202 is fixed to the top end of the connecting rod 204. Liquid cylinders are fixed to the side of the base plate 201, and the ends of the liquid cylinders are threadedly connected to a device inserted inside the liquid cylinder. The device has a threaded rod at one end, with a piston fixed to it that fits tightly against the inner wall of the liquid cylinder. Both the liquid cylinder and the inner cavity 206 are filled with a certain amount of liquid, such as water or hydraulic oil. By rotating the threaded rod, the piston moves within the liquid cylinder, forcing the liquid into the inner cavity 206. This creates hydraulic pressure within the inner cavity 206, which in turn pushes the piston plate 203 downward within the liquid cylinder 202. This, in turn, moves the support plate 205 downward until it contacts the ground, simultaneously lifting the casters 10. This achieves stable placement of the entire device, combining convenient movement and stable placement into a single unit. This facilitates relocation and improves overall practicality.

[0022] Further as Figure 5 As shown, it is worth noting that the side of the rubber roller 8 is provided with a number of equidistant ribs 12; the ribs 12 on the surface of the rubber roller 8 are 2mm deep and 15mm apart, which further increases the friction with the cable of the rubber roller 8 and prevents slippage.

[0023] In summary: Operators can adjust the tilt angle of the inner frame 3 and the rubber roller 8 by rotating them according to the actual cable routing requirements. The inner frame 3 is then locked after adjustment using the locking component 1. This allows for easy adjustment of the tilt angle of the rubber roller 8, enabling the system to adapt to different cable deployment and retraction angles. The system is simple to operate, requires no special tools, and can handle changes in ship height caused by tidal variations. It is highly adaptable, has a relatively simple overall structure, and is highly practical. The stabilization component 2 combines convenient movement and stable placement of the entire device into one unit, facilitating relocation and effectively improving overall practicality.
