Figure 3 is a side view of the preferred embodiment of the invention in use on a marine vessel.
Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
As shown in fig. 1 and 2, a large-sized cargo lid for a ship is provided on a cargo wall 10; the two cover plates 20 are openable in the port and starboard outward directions, respectively, and upper ends of the two cover plates 20 are in contact with each other. The cover plate 20 is distributed obliquely from the upper end to the lower end.
After the two cover plates are connected, the joint of the two cover plates is highest, and the joint of the two cover plates is gradually reduced towards two sides. This can prevent rainwater or seawater from accumulating on the cover plate.
A sealing member 21 is provided between the upper end portions of the two cover plates 20. The material of the sealing component is rubber.
A locking device (not shown) for pressing the sealing member is further provided between the upper ends of the two cover plates 20. In this embodiment, the locking device is a hydraulic locking device.
The cover panel 20 includes an open panel beam structure 22 and a rain cover 23 overlying the open panel beam structure.
The cover plate 20 is hinged to the top of the cargo bulkhead 10 by a hinge 25.
A rubber sealing strip 13 is provided between the cover plate 20 and the top of the cargo bulkhead 10. The rubber sealing strip is provided with a water flowing groove. The material of the rubber seal strip 13 may be ethylene propylene diene monomer (EPMD).
The upper part of the cargo compartment wall 10 is provided with an accommodating cavity 11, and a hydraulic oil cylinder 12 for driving the cover plate to rotate is arranged in the accommodating cavity 11.
The lower end of the cover plate 20 is hinged to the top of the hydraulic ram 12. The hinge of the cover plate 20 and the bulkhead 10 is located above the lower end of the cover plate 20.
A first stop block 31 for preventing the lower end part of the cover plate from continuously rotating when the cover plate reaches a closed position is further arranged in the accommodating cavity 11; a second stop bump 32 for preventing the lower end of the cover plate from rotating further when the cover plate is at the maximum opening position is further arranged in the accommodating cavity 11.
A control unit (not shown) for independently controlling the hydraulic cylinders is connected to each corresponding hydraulic cylinder of the cover plate 20.
A hydraulic pump station (not shown in the figure) is arranged on the ship; the hydraulic cylinder is connected with a hydraulic pump station.
A plurality of cover plates 20 are provided from the bow to the stern according to the size of the cargo. For example, 2 pairs of cover plates, 3 pairs of cover plates, or 4 pairs of cover plates, etc. may be provided. As shown in fig. 3, the ship is provided with 4 pairs of cover plates 20.
As shown in fig. 3, the large-sized cargo hatch for ships further includes a stern cover 24 openable in the stern direction, and the stern cover is hinged to the cargo hatch near the stern.
In the invention, the cover plate 20 takes an open plate girder structural member 22 as a main structural framework, and the frameworks are filled with a rain shielding covering member 23, so as to meet the requirement of water-proof performance and provide a proper shielding space for the cargo hold. The cover plate is designed to be inclined so as to prevent water accumulation. When the cover plate is in a fully closed position, the hydraulic locking device locks to tightly press the rubber seal so as to ensure the sealing of the cabin. When the cover plate is in a fully closed position, the hydraulic locking device locks to tightly press the rubber seal so as to ensure the sealing of the cabin.
