Description
Technical field
It the utility model is related to a kind of watertight hatch, more particularly to a kind of square flush type watertight hatch.
Background technology
At present, in bulk freighter or chemical tanker, it is provided with the ship of keeping coal, cement, cereal and chemicals etc.
Cabin, there are multiple hatch on ship, and sealed provided with hatch board, after goods has loaded, hatch board closes up so that in ship
In the transportation of oceangoing ship, will not rain or other foreign matters enter cabin and influence freight.
Hatch board in domestic big-and-middle-sized navigation mark work deck is folding hatch cover, this hatch board and hatch coaming
The center in whole deck effective operation region is occupied, buoy can only be loaded in both sides, cause the buoy quantity of ship loading
Reduce, working space is very crowded, and operating efficiency is low.During lifting operation, operating personnel, which needs to stand, is being higher by deck more than half meter
Jumped on hatch board, abnormally dangerous, especially poor in sea situation, in the case that ship motion is larger, operating personnel Chang Huiyu is floated
Mark collision, tripped or even crash into sea, larger potential safety hazard be present.
Utility model content
For drawbacks described above, the purpose of this utility model is to provide a kind of simple in construction, operating efficiency height, sealing
A kind of good, safe square flush type watertight hatch.
Technical scheme is used by for this utility model：
Including square hatch board frame and hatch board, the hatch board is arranged on square hatch board frame, the square hatch
Lid inframe is provided with the L-type folded plate to infolding, and the inner edge of the L-type folded plate welds vertical sealing plate, hatch board side upper table
Face is connected by hinge with square hatch board frame, and hatch board lower surface outward flange connects with the sealing of vertical sealing plate top edge
Touch, the hatch cap upper surface is concordant with square hatch board frame upper surface.
As the further improvement of above-mentioned technical proposal, hatch board lower surface outward flange is provided with groove, the groove
Interior to be provided with sealing gasket, the vertical sealing plate upper end is located in groove.
It is cavity inside the hatch board, the hatch board thickness is therefrom as the further improvement of above-mentioned technical proposal
The heart is gradually thinning to surrounding.
The utility model has the advantages that：
The utility model is simple in construction, by using embedded structure so that hatch board is concordant with deck, improves deck
Upper operating efficiency, and hatch board good airproof performance, improve security.
