Description

Technical Field

[0001] This application relates to the field of shore power cables, and more particularly to a cable connection device for dock ships. Background Technology

[0002] When a ship docks, it needs to connect to shore power in order to maintain the normal operation of onboard equipment, provide living facilities such as lighting and air conditioning, and meet the daily needs of crew and passengers.

[0003] The vessel is equipped with a dedicated shore power cable. One end of the shore power cable connects to the shore power box or power distribution system on board, and the other end connects to the shore power supply at the dock. When the distance between the dock's shore power supply and the vessel's berthing location is too far, or when the shore power cable is not long enough, it is necessary to drag an extension cable from the ground to connect with the shore power cable to make up the cable length and ensure that power can be transmitted smoothly.

[0004] Regarding the aforementioned technologies, the inventors believe that during the process of dragging the extension cable from a distance to connect with the shore power cable, the friction between the extension cable and the ground increases continuously with the increase of the dragging distance, making it difficult for workers to move the extension cable, and there is still room for improvement. Utility Model Content

[0005] To address the issue that the friction between the extension cable and the ground increases with the towing distance during the connection of the extension cable to the shore power cable, making it difficult for workers to move the extension cable, this application provides a dock ship cable connection device.

[0006] The technical solution for a dock ship cable connection device provided in this application is as follows:

[0007] A dock ship cable connection device includes a mounting frame, a winch rotatably connected to the mounting frame for winding an extension cable, and a shore power supply fixedly connected to the mounting frame.

[0008] By adopting the above technical solution, the extension cable is wound on the winch. When dragging, the winch rotates, which transforms the sliding friction between the cable and the ground into rolling friction of the winch rotation. This greatly reduces the friction generated during dragging, saves the force required for workers to drag the extension cable, and improves the convenience for workers to drag the extension cable.

[0009] Optionally, the mounting bracket is hinged with a power cover for concealing the connection port of the shore power supply.

[0010] By adopting the above technical solution, the power supply cover can shield the connection port of the shore power supply, preventing common environmental contaminants such as rainwater, dust, sand, and oil from entering the connection port and preventing safety hazards such as short circuits and leakage caused by foreign objects. On the other hand, the power supply cover in the closed state can physically isolate live parts, preventing workers or other personnel from accidentally touching the connection port and causing electric shock accidents, thus significantly improving the safety of the cable connection device of the ship at the dock.

[0011] Optionally, sliding rods are fixedly connected to both sides of the power supply cover, and a pull rod is hinged to the mounting bracket. The pull rod is provided with a guide groove for the sliding rod to slide and connect. The guide groove includes a sliding groove and a fixing groove that are interconnected. When the sliding rod slides into the fixing groove, the power supply cover is in the open state.

[0012] By adopting the above technical solution, the staff can rotate the pull rod to drive the slide rod to slide in the guide groove, and simultaneously open or close the power cover, which simplifies the operation steps of the staff and improves the efficiency of the staff in opening the power cover.

[0013] Optionally, a locking rod is provided through the bottom of the sliding groove to limit the sliding rod. When the sliding rod slides into the fixed groove, the locking rod abuts against the side of the sliding rod near the sliding groove.

[0014] By adopting the above technical solution, when the slide bar slides into the fixed groove (the power cover is fully open), the locking rod abuts against the side of the slide bar near the sliding groove, forming a physical block, eliminating the need for hand-held operation and improving the convenience of keeping the power cover in the open state. On the other hand, during the charging process, keeping the power cover in the open state can prevent the power cover from closing and squeezing the extension cable, thus providing a certain degree of protection for the extension cable.

[0015] Optionally, a limiting block is fixedly connected to the side of the locking rod near the power cover, and a limiting cylinder for the locking rod to pass through is fixedly connected to the side of the pull rod away from the power cover. When the limiting block abuts against the side of the limiting cylinder near the power cover, the slide rod slides freely in the guide groove.

[0016] By adopting the above technical solution, the locking rod is inserted into the limiting cylinder. The inner wall of the limiting cylinder can limit the radial sway of the locking rod, thereby improving the stability of the locking rod inserted into the pull rod. When the limiting block abuts against the limiting cylinder, the pull-out depth of the locking rod is fixed, ensuring that the locking rod will not fall off the pull rod in the unlocked state, further improving the stability of the locking rod inserted into the pull rod.

[0017] Optionally, a grip sleeve is fixedly connected to the side of the locking rod away from the power cover. When the grip sleeve abuts against the side of the limiting cylinder away from the power cover, the sliding position of the slide rod is restricted.

[0018] By adopting the above technical solution, the grip sleeve provides workers with a more comfortable point of force application, making it easier to quickly insert and remove the locking rod and improving operating efficiency. On the other hand, the abutting relationship between the grip sleeve and the limiting cylinder can further restrict the axial movement of the locking rod. The grip sleeve and the limiting block work together to prevent the locking rod from falling off during operation, thus improving the reliability of the overall structure.

[0019] Optionally, the sliding groove extends through the side of the pull rod away from the shore power source on the side of the fixed groove near the sliding groove, so that the sliding rod can disengage from the guide groove.

[0020] By adopting the above technical solution, the slide bar can be completely detached from the side of the sliding groove that passes through the pull rod, so that the power cover is separated from the pull rod. This makes it convenient for staff to inspect or replace the power cover or pull rod separately without disassembling the whole or damaging other structures, thus improving the maintainability and component versatility of the dock ship cable connection device.

[0021] Optionally, the mounting bracket has reinforcing ribs.

[0022] By adopting the above technical solution, the reinforcing ribs can effectively resist bending and torsional deformation caused by external forces (such as cable pulling, equipment vibration, environmental wind force, etc.) by increasing the moment of inertia of the mounting frame, thereby improving the stability of the mounting frame supporting winches, shore power supply, extension cables and other related components.

[0023] Optionally, the mounting bracket has a base at its bottom.

[0024] By adopting the above-mentioned technical methods and adding a heavier base to lower the center of gravity of the entire device, the device can be reduced from being overturned by horizontal external forces such as cable dragging and ship docking impacts, thus improving the stability of the dock ship cable connection device when subjected to horizontal forces.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. In this application, the extension cable is wound on a winch. When dragging, the winch converts the sliding friction between the cable and the ground into rolling friction, which improves the convenience of dragging the extension cable.

[0027] 2. The power supply cover prevents rainwater, dust, and other common pollutants found in dock environments from entering the wiring ports, thus preventing accidental contact by staff and preventing electric shock accidents, thereby improving the safety of the device;

[0028] 3. By rotating the pull rod, the slide bar is driven to slide in the guide groove, which simultaneously opens or closes the power supply cover, simplifying the operation steps and improving the efficiency of the staff in opening the power supply cover. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a cable connection device for dock ships.

[0038] Reference Figure 1 and Figure 2 The dockside vessel cable connection device includes a base 1, a mounting frame 2, a winch 3, and a shore power supply 4. The mounting frame 2 is fixedly connected to the base 1 for mounting the winch 3 and the shore power supply 4. The winch 3 is rotatably connected to the mounting frame 2 for winding extension cables. The shore power supply 4 is fixedly connected to the mounting frame 2 to provide power to the vessel after the extension cable is connected.

[0039] Reference Figure 1 and Figure 2The mounting frame 2 includes a base frame 21, four uprights 22, two crossbars 23, and a power supply box 24. The base frame 21 is fixedly connected to the base 1, and the four uprights 22 are fixedly connected to the four corners of the base frame 21 respectively. To enhance the structural stability between the base frame 21 and the uprights 22, reinforcing ribs 221 are fixedly connected to the uprights 22. The crossbars 23 are fixedly connected to the ends of the two uprights 22 on the same side away from the base frame 21. Each of the two crossbars 23 has a lug 231 fixedly connected to it, and a mounting rod 232 is also installed on the crossbar 23. The two ends of the mounting rod 232 are fixedly connected to the two lugs 231 respectively for the installation of the winch 3 and the shore power supply 4. The winch 3 is fitted onto the mounting rod 232 to allow the winch 3 to rotate and connect to the mounting frame 2. Limiting discs 31 are fixedly connected to both sides of the winch 3 to prevent the extension cable from detaching from the sides of the winch 3.

[0040] Reference Figure 2 and Figure 3 The power supply box 24 is fixedly connected to the mounting rod 232 for the installation of the shore power supply 4. In order to prevent foreign objects such as rainwater, dust, sand, and oil, which are common in the dock environment, from entering the wiring port of the shore power supply 4, a power supply cover 241 is hinged on the power supply box 24 to cover the wiring port of the shore power supply 4 when it is not in operation.

[0041] Reference Figure 3 and Figure 4 Both sides of the power supply cover 241 are fixedly connected to sliding rods 2411, and the power supply box 24 is also hinged to a pull rod 242. Both sides of the pull rod 242 have sliding grooves 2431 and fixing grooves 2432. The fixing groove 2432 is located at the end of the sliding groove 2431 away from the hinge point of the pull rod 242, and the sliding groove 2431 and the fixing groove 2432 are interconnected and cooperate to form a guide groove 243 for the sliding rod 2411 to slide and connect. Two sliding rods 2411 are respectively embedded and slide in two guide grooves 243 to realize that rotating the pull rod 242 drives the power cover 241 to open or close synchronously: when rotating the pull rod 242 drives the sliding rod 2411 to slide into the fixed groove 2432, the power cover 241 is in the open state; when rotating the pull rod 242 drives the sliding rod 2411 to slide to the end of the sliding groove 2431 away from the fixed groove 2432, the power cover 241 is in the closed state.

[0042] Reference Figure 4-6To lock the power supply cover 241 in its open state, the pull rod 242 has a locking assembly 244. The locking assembly 244 includes a locking rod 2441, a limiting cylinder 2442, a limiting block 2443, and a grip sleeve 2444. The locking rod 2441 passes through the bottom of the sliding groove 2431. The limiting cylinder 2442 is fitted onto the locking rod 2441 and is fixedly connected to the side of the pull rod 242 away from the power supply cover 241, so that the locking rod 2441 moves only along its own length. The limiting block 2443 is fixedly connected to the side of the locking rod 2441 near the power supply cover 241. When the locking rod 2441 is pulled away from the power supply cover 241, the limiting block 2443 abuts against the side of the limiting cylinder 2442 near the power supply cover 241, at which point the locking rod 2441 is pulled away from the bottom of the sliding groove 2431.

[0043] Reference Figure 4 and Figure 6 The grip sleeve 2444 is fixedly connected to the end of the locking rod 2441 away from the power cover 241 for the operator to grip. When the sliding rod 2411 slides into the fixing groove 2432, it pushes the locking rod 2441 to move closer to the power cover 241. The grip sleeve 2444 abuts against the side of the limiting cylinder 2442 away from the power cover 241, and the locking rod 2441 abuts against the side of the sliding rod 2411 near the sliding groove 2431, preventing the sliding rod 2411 from sliding within the guide groove 243. At this time, the distances between the hinge points of the sliding rod 2411 and the power cover 241, the sliding rod 2411 and the pull rod 242, and the power cover 241 and the pull rod 242 are all fixed values. When the lengths of the three sides of the triangle are determined, the shape and size of the triangle are completely determined, that is, the angle at which the power cover 241 is opened is locked.

[0044] Reference Figure 4 In order to allow for separate repair or replacement of the power supply cover 241 in case of damage, the sliding groove 2431 passes through the side of the pull rod 242 away from the power supply box 24 on the side near the fixed groove 2432. This allows the staff to separate the pull rod 2411 from the guide groove 243 from the side of the pull rod 242 through which the sliding groove 2431 passes, thereby separating the power supply cover 241 and the pull rod 242.

[0045] The implementation principle of the dock ship cable connection device in this application embodiment is as follows: when the extension cable is pulled closer to the shore power cable of the ship, the winch 3 rotates and converts the sliding friction of directly dragging the extension cable into rotational friction, providing operational convenience.

[0046] When shore power 4 needs to be connected, hold the grip sleeve 2444 and pull the locking rod 2441 away from the power cover 241. The limiting block 2443 abuts against the limiting cylinder 2442. Pull the pull rod 242 to rotate away from the base 1. The sliding rod 2411 slides in the guide groove 243, and the power cover 241 rotates synchronously. When the sliding rod 2411 slides into the fixing groove 2432, push the locking rod 2441 towards the power cover 241. The grip sleeve 2444 abuts against the limiting cylinder 2442. At this time, the locking rod 2441 abuts against the side of the sliding rod 2411 near the sliding groove 2431, and the power cover 241 remains open.

[0047] When the power cover 241 needs to be replaced, rotate the pull rod 242 slightly so that the slide rod 2411 slides a certain distance closer to the fixing groove 2432. Then rotate the power cover 241 separately so that the slide rod 2411 is disengaged from the pull rod 242 from the side through which the guide groove 243 passes. Then the power cover 241 can be disassembled.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
