Description

Technical Field

[0001] This utility model relates to the field of cable reel technology, specifically to a shore power cable reel. Background Technology

[0002] During ship berthing operations, shore power cable reels are key equipment for connecting ships to the dock's shore power system. By winding up and unwinding shore power cables through the reels, clean power can be provided to ships, replacing the operation of the ships' own generators.

[0003] However, existing shore power cable reels lack corresponding cable support and guidance structures in actual use. After the cable is released from the reel, it is in direct contact with the dock surface throughout the entire process. During the dragging and pulling process, the cable surface is prone to friction and collision with rough parts and sharp protrusions on the ground, causing wear and cracking of the outer sheath. This not only shortens the cable's service life but may also damage the insulation layer and cause leakage risks. Moreover, shore power cables are usually thick in diameter and heavy in order to meet the needs of high-power power transmission. However, the reel only has basic winding and unwinding functions and lacks auxiliary labor-saving mechanisms. A single person cannot complete the dragging, alignment, and connection of the cable. It is necessary to rely on the cooperation of multiple crew members or dock workers, which not only results in high labor intensity but also high personnel coordination costs and low work efficiency. Especially in emergency docking or personnel shortage scenarios, it seriously affects the timeliness of shore power connection. Therefore, we propose a shore power cable reel. Utility Model Content

[0004] The purpose of this utility model is to provide a shore power cable reel that has the advantages of a cable support and guidance structure and auxiliary cable winding and unwinding. It solves the problem that existing shore power cable reels lack a corresponding cable support and guidance structure in actual use. After the cable is unwound from the reel, it is in direct contact with the dock surface throughout the entire process. During the dragging and pulling process, the cable surface is prone to friction and collision with rough parts and sharp protrusions on the ground, causing wear and cracking of the outer sheath. This not only shortens the service life of the cable, but may also damage the insulation layer and cause leakage risks. Moreover, shore power cables are usually thick and heavy to meet the requirements of high-power power transmission. However, the reel only has basic winding and unwinding functions and lacks auxiliary labor-saving mechanisms. It is impossible for a single person to complete the dragging, alignment and connection of the cable. It must rely on the cooperation of multiple crew members or dock workers, which not only has high labor intensity, but also has the problems of high personnel coordination costs and low work efficiency.

[0026] Example 1

[0027] Please see Figures 1-5 As shown, this utility model provides a shore power cable reel technical solution: a shore power cable reel, comprising:

[0028] Base frame 1, support bracket 2, and positioning seat 4;

[0029] Among them, a support 101 is installed at the middle of the top of the base frame 1, and a reel body 103 is provided at the upper end of the inner side of the support 101. A drive motor 104 and a control box 102 are respectively installed at the upper and lower ends of one side of the support 101, and the output end of the drive motor 104 is fixedly connected to one side of the reel body 103.

[0030] Among them, the support bracket 2 is installed at the right end of the top of the base frame 1. The upper end of the support bracket 2 is movably connected to a number of transmission shafts 203 through bearings. The outer surface of the transmission shaft 203 is fixed with a transmission wheel 205. An auxiliary motor 204 is installed on one side of the support bracket 2, and the output end of the auxiliary motor 204 is fixedly connected to the transmission shaft 203.

[0031] The positioning seat 4 is fixed above the transmission wheel 205 on the inner side of the support bracket 2. A spring 401 is fixed on the top of the inner side of the positioning seat 4. One end of the spring 401 is fixed with a guide plate 402 that slides on the inner side of the positioning seat 4. An auxiliary pressure roller 403 is installed at the bottom of the guide plate 402.

[0032] The support bracket 2 is composed of multiple L-shaped support plates distributed at equal intervals. A double-groove pulley 201 is fixed on one side of the drive shaft 203. A synchronous toothed belt 202 is sleeved on the inner side of the double-groove pulley 201. The output end of the control box 102 is electrically connected to the output ends of the drive motor 104 and the auxiliary motor 204 through wires. The output end of the laser range sensor 301 is electrically connected to the input end of the control box 102 through wires.

[0033] This technical solution involves: The entire equipment base frame 1 is securely positioned near the shore power junction box at the dock, and the control box 102 is connected to mains power. Then, the cable end is led out from the reel body 103 and sequentially passed through the gap between multiple drive rollers 205 supported by the support bracket 2 and the auxiliary pressure roller 403 under the positioning seat 4. Under the action of the spring 401 and guide plate 402, the auxiliary pressure roller 403 gently and stably presses the cable against the drive rollers 205 below, completing the cable threading. This raises the cable height, preventing direct contact between the cable and the ground. The operator starts the equipment and enters the cable laying mode via the control box 102. At this time, the operator holds the cable connector and walks towards the ship's interface, dragging the cable. Simultaneously, the drive motor 104 drives the reel body 103 to unwind the cable. Meanwhile, the laser rangefinder 301, with the assistance of the auxiliary support 3, monitors the cable movement and synchronously transmits the monitoring data to the control box 102. The controller (such as a PLC) inside the control box 102 processes the data and then activates the auxiliary motor 204 to drive the drive shaft 203 to rotate. When in operation, with the cooperation of the double-grooved pulley 201 and the synchronous toothed belt 202, all drive shafts 203 and drive rail wheels 205 can rotate synchronously, thereby enabling auxiliary transmission of the cable, greatly saving manpower. When the ship has finished its operations and needs to leave port, the operator switches to the cable reel mode through the control box 102, and the drive motor 104 reverses to act as the main force for cable recovery. The reel body 103 begins to reel in the cable, and the laser rangefinder 301 detects that the cable is moving back. The control box 102 then commands the auxiliary motor 204 to rotate synchronously in a direction and speed that matches the cable reel speed. The synchronous auxiliary rotation of the drive wheel 205 ensures that the cable is smoothly and neatly guided and retracted onto the reel, effectively preventing the cable from becoming loose, tangled, or colliding with the equipment frame during the winding process. Throughout the process, the cable is always lifted off the dock ground and moves smoothly in the track formed by the drive wheel 205 and the auxiliary pressure wheel 403, which has both protection and guiding functions. The synchronous toothed belt 202 transmission system ensures the consistency of the movement of multiple drive wheels 205, enabling this equipment to achieve a fundamental transformation from manual dragging to human guidance and machine drive, making it safe, efficient, and labor-saving.

[0034] Example 2

[0035] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a cleaning pad 206 is adhered to the inner side of the drive wheel 205.

[0036] This technical solution: By setting the cleaning pad 206, the surface of the cable can be wiped during cable winding, ensuring the surface cleanliness of the cable during winding.

[0037] Example 3

[0038] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, an auxiliary support 3 is installed on the upper end of the support bracket 2, and a laser rangefinder sensor 301 is installed at the bottom of one end of the auxiliary support 3.

[0039] This technical solution uses a laser rangefinder 301 to detect cable movement in real time and intelligently coordinates the rotation speed of the reel and drive wheel to ensure a smooth, synchronous, and uninterrupted winding and unwinding process, thereby improving the smoothness, safety, and reliability of the operation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
