Floatable hatch cover of independent cargo cabin

Abstract

The invention discloses a floatable hatch cover of an independent cargo cabin. The cargo cabin adopts a double-layer structure of an independent cargo cabin panel and a delivery vehicle structure panel, and a gap exists between the independent cargo cabin panel and the delivery vehicle structure panel; the hatch cover comprises a cargo cabin cover plate and a small hatch cover arranged on the cargo cabin cover plate, the cargo cabin cover plate is connected with the independent cargo cabin panel through an inner hatch coaming, and the edge of the cargo cabin cover plate is connected through a rubber sealing ring with the inner hatch coaming connected onto the delivery vehicle structure panel. The hatch cover has the advantages as follows: by the aid of the hatch cover, floating connection of the independent cargo cabin and a delivery vehicle structure can be realized, and the watertightness of the external structure of a delivery vehicle can also be guaranteed.

Description

technical field [0001] The invention relates to a floatable independent cargo hold hatch cover. The utility model relates to a hatch cover suitable for an independent cargo compartment in a transportation vehicle, and belongs to the technical field of manufacturing transportation vehicles such as ships and automobiles. Background technique [0002] In the manufacture of transportation vehicles such as ships and automobiles, due to the diversity of the physical properties of the medium being carried, during the transportation process, the medium often requires heat preservation measures such as heating (such as asphalt) or freezing. The thermal expansion and contraction effect caused by the huge temperature difference, as well as the structural deformation caused by the uneven loading of the large cargo tank itself, cause a large internal stress inside the cargo tank structure, which seriously affects the structural safety of the cargo tank and even the vehicle itself. There...

AI Technical Summary

Problems solved by technology

Obviously, this kind of cargo hatch cover cannot realize the floating connection between the cargo compartment and the vehicle, and cannot be applied to independent cargo compartments

[0004] On the other hand, on the independent cargo hold, there are often a large number of accessories and equipment such as connecting pipes and sensors connected to the delivery vehicle. Due to the shape and space of the independent cargo compartment, it will also have a bad impact on its structure in terms of strength and rigidity
