The ship should have good movement performance in waves, good comfort during navigation, be able to berth accurately at the foundation of the wind turbine at low speed, and be able to maintain contact with the foundation, and be able to safely and conveniently transport personnel and equipment to the wind turbine. When the ship is docked, most of the power is supplied to the electrical equipment on board by taking electricity from the shore. The specifications of the shore power cable are calculated and determined according to the corresponding working conditions of the power load. The shore power box will be installed inside the cabin for waterproof considerations. When the shore power cable needs to be connected, the shore power cable needs to be pulled from the inside of the cabin to the shore. At this time, the shore power cable is usually led out from the cabin door, so the cabin door is bound to be in an open state for a long time, and there is a risk of the cable being stepped on by people and squeezed by the door, thereby damaging the cable.

[0003] A hull hatch structure is disclosed in the patent with the announcement number CN209112395U. When in use, the cover is first removed, and then the shore power cable can be pulled to the shore through the barrel. In rainy days, rainwater will enter the cabin through the barrel, affecting the internal environment of the cabin. Utility Model Content

[0017] In the above technical solution, the pressure plate can press the rubber ring onto the cylinder body, thereby improving the sealing performance of the rubber ring to the cylinder body, and further reducing the possibility of water entering the hull when the cover plate is removed.

[0018] Furthermore, the rubber ring is provided with an annular groove, and the axis of the annular groove is consistent with the axis of the rubber ring. The pressing plate is annular, and the annular groove is used for the pressing plate to be inserted.

[0019] In the above technical solution, the pressing plate is annular, and the annular groove is used for the pressing plate to be inserted, so that the pressing plate can more comprehensively press the annular end surface of the cylinder body through the rubber ring, and the sealing effect is better.

[0020] In summary, the present application has the following technical effects: the shore power cable in the hull can be pulled to the shore through the cylinder body, and a rubber ring is installed at one end of the cylinder body in the length direction close to the outside of the hull, and the inner ring of the rubber ring can contact the axial outer wall of the shore power cable, and the diameter of the inner ring of the rubber ring is smaller than the diameter of the axial outer wall of the shore power cable. This design can prevent rainwater from entering the hull through the cylinder body on rainy days and polluting the internal environment of the hull. When the shore power cable is retracted into the hull through the cylinder body after use, the rubber ring can scrape off the rainwater on the outer wall of the shore power cable, so that the rainwater on the outer wall of the shore power cable is not easy to enter the interior of the hull. When the cover plate is installed on the cylinder body, the end face of the rubber ring can contact the inner wall of the cover plate, thereby improving the sealing of the cover plate.

A barrel 2 is welded to the hatch 12 and is inserted through the hatch 12. The barrel 2 is placed horizontally, and a hole 22 for the shore power cable to pass through is formed through the barrel 2 along its own axis. When the shore power box is arranged inside the hull 1, the shore power cable can be pulled out to the shore through the hole 22. One end of the barrel 2 in the length direction outside the hull 1 is detachably connected to a cover plate 3, and the axial outer wall of the barrel 2 is formed with a thread 21, and the barrel 2 can be connected to the cover plate 3 through the thread 21. When it is not necessary to pull the shore power cable to the shore, the cover plate 3 can be installed on the barrel 2 to prevent external dust and other impurities from entering the hull 1.

[0028] Please refer to the attached drawings in the instruction manual. Figure 1 and Figure 3 The cover plate 3 is fixed to the hatch 12 by a connecting line 5, and this design can prevent the cover plate 3 from being lost. The thickness outer wall of the cover plate 3 is formed with anti-skid lines 31, which can prevent workers from slipping when turning the cover plate 3.

[0029] Please refer to the attached drawings in the instruction manual. Figure 2 The end surface of the barrel 2 near the cover plate 3 is detachably mounted with a rubber ring 4, the axis of the rubber ring 4 is consistent with the axis of the barrel 2, the end surface of the rubber ring 4 can contact the end surface of the barrel 2, the inner ring of the rubber ring 4 is used to pass the shore power cable, and the diameter of the inner ring of the rubber ring 4 is smaller than the diameter of the axial outer wall of the shore power cable. When the axial outer wall of the shore power cable contacts the inner ring of the rubber ring 4, it can squeeze the inner ring of the rubber ring 4, thereby expanding the inner ring of the rubber ring 4. This design can reduce the possibility of external rainwater entering the hull 1 through the barrel 2 when the shore power cable is passed through the barrel 2. In the process of retracting the shore power cable through the barrel 2, the inner ring of the rubber ring 4 can scrape off the rainwater on the shore power cable, reducing the possibility of rainwater entering the hull 1. After the cover plate 3 is installed on the barrel 2, the end surface of the rubber ring 4 can contact the end surface of the inner wall of the cover plate 3. This design can improve the sealing performance of the cover plate 3 and further reduce the possibility of rainwater entering the hull 1 through the cover plate 3.

[0030] Please refer to the attached drawings in the instruction manual. Figure 2 and Figure 4, an annular groove 41 is provided at one end of the rubber ring 4 away from the barrel 2, the axis of the annular groove 41 coincides with the axis of the rubber ring 4, and the annular groove 41 is used for a pressing plate 8 to be inserted, the pressing plate 8 is annular, the pressing plate 8 and the rubber ring 4 are fixed to the end face of the barrel 2 by screws 7, there are three screws 7, and the three screws 7 are simultaneously and sequentially threadedly connected to the pressing plate 8, the rubber ring 4 and the barrel 2. After the screws 7 are installed, the end face of the rubber ring 4 away from the barrel 2 can abut against the end face of the inner wall of the cover plate 3. The rubber ring 4 will age and break after being used for a period of time, thereby affecting its own sealing performance. This design facilitates the removal and replacement of the rubber ring 4. By setting the annular pressing plate 8, the pressing plate 8 can apply force to the rubber ring 4 so that the rubber ring 4 is tightly attached to the end face of the barrel 2, improving the fit between the rubber ring 4 and the end face of the barrel 2, and reducing the possibility of water entering the interior of the hull 11 through the gap between the rubber ring 4 and the barrel 2 when the cover plate 3 is removed.
