Square embedded watertight hatch cover

Abstract

The invention relates to the field of hatch covers, and discloses a square embedded watertight hatch cover. The hatch cover comprises a hatch, mounting plates are arranged on the outer surfaces of the two ends of the hatch, mounting bolts are arranged in the mounting plates in a penetrating mode, a sealing ring is arranged on the outer surface of the upper end of the hatch, and a protection mechanism is arranged on the surface of the inner side of the hatch. And a rotating mechanism is arranged on the outer surface of the upper end of the mounting plate. According to the square embedded watertight hatch cover, people can be prevented from sliding into a hatch accidentally through the protective net under the condition that the hatch cover is not closed, the prevention effect can be achieved, accidents are prevented, the situation that a rotating mechanism is broken due to overexertion in the using process is avoided, the hatch cover can be fixed conveniently, and fixation is firm; and the fixing mode is flexible, the structure is simple, the situation of the inner side of the hatch can be observed without opening the hatch cover, flexibility is achieved, and trouble is saved.

Description

technical field [0001] The invention relates to the field of hatch covers, in particular to a square embedded watertight hatch cover. Background technique [0002] The hatch cover is the closing device for the deck opening in the cargo area of ​​the ship, which belongs to the passage device for vertical cargo loading and unloading. The hatch cover on the weather deck is a weather-tight hatch cover. When the cargo tank doubles as a ballast water tank, the hatch cover on the weather deck is still weather-tight Mode. The middle deck hatch covers are generally non-tight hatch covers. In addition to being used as a closing device, the hatch cover can also carry various deck cargoes, such as general cargo, timber, containers and other goods. hatch covers, folding hatch covers for general cargo ships. Among them, the foldable hatch cover can also be used on a bulk carrier whose hatches are connected, and the lift-off hatch cover can also be used on a general cargo ship. If the ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a square embedded watertight hatch cover. The protective net can prevent people from accidentally slipping into the hatch when the hatch cover is not closed, which can play a preventive role and prevent accidental accidents. It will not occur when the rotating mechanism breaks due to excessive force during use. It is convenient to fix the hatch cover, the fixation is relatively firm, the fixing method is more flexible, the structure is relatively simple, and it can be done without opening the hatch cover. Observing the situation on the inside of the hatch, it is more flexible and less troublesome. It solves the problem that the traditional square embedded watertight hatch cover and the hatch are connected by hinges. The hinges are not strong enough and easy to disconnect. The caliber is large and has no protective effect. It is easy to step on the hatch if you are not careful, endangering the safety of personnel. In addition, the fixing method of the hatch cover is more complicated and the fixation is not firm enough. Finally, once the hatch cover is closed, people outside will not be able to see it. To the internal situation, you need to open the hatch cover to wipe the internal situation
