A kind of triplet liquefied gas storage peculiar to vessel
Technical field
The utility model relates to a kind of triplet liquefied gas storage peculiar to vessel.
Background technology
All the time, in liquefied gas transport independent C type storage tank peculiar to vessel and pressure container field, its traditional tank structure form adopts horizontal single cylinder (see Fig. 1 a and Fig. 1 b) or duplex cylinder (see Fig. 2 a and Fig. 2 b), because the tank volume of these two kinds of forms is less, therefore cargo space degree of utilization is lower.The liquefied gas carrier of the type, establish three cargo holds in every ship, former total volume is bound in less than 30,000 cubes mostly, is difficult to break through larger volume, is thus difficult to adapt to international liquefied gas carrier market to demand that is medium-sized, large scale development.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides a kind of triplet liquefied gas storage peculiar to vessel, and it can improve volume and the flow container under greatly saving same volume and the material weight needed for surrounding hull cargo hold thereof and engineering cost greatly.
The purpose of this utility model is achieved in that a kind of triplet liquefied gas storage peculiar to vessel, comprises longitudinally the crouch left tank body in each cargo hold of hull, right tank body and upper tank body, wherein,
Described left tank body and right tank body are symmetrical arranged and are located at lower left quarter and the right lower quadrant of described cargo hold correspondingly, the lower right side of described left tank body and the left lower of right tank body are close together and by a centerline bulkhead isolation, make the spatial accommodation forming a upper tank body between the left upper portion of the right upper portion of left tank body and right tank body;
Described upper tank body is located at the central upper of cargo hold and is positioned at the spatial accommodation of described upper tank body, the left side of this upper tank body and the top of left tank body are close together and are isolated by a left longitudinal bulkhead and left tank body, and the right side of this upper tank body and the top of right tank body are close together and are isolated by a right longitudinal bulkhead and right tank body; Described left longitudinal bulkhead, right longitudinal bulkhead and centerline bulkhead form Y shape and are connected on cross-sectional plane, make left tank body, right tank body and upper tank body form isosceles triangle and arrange.
Above-mentioned triplet liquefied gas storage peculiar to vessel, wherein, the shape of cross section C shape in abnormity identical with the shape of cross section of right tank body of described left tank body, the lower right side of left tank body and the left lower of right tank body are connected in the both side surface of centerline bulkhead correspondingly, make the spatial accommodation of described upper tank body V-shaped; The shape of cross section of described upper tank body is the fan-shaped of abnormity, and two sides of this upper tank body on cross-sectional plane are connected to the upper surface of described left longitudinal bulkhead and the upper surface of right longitudinal bulkhead correspondingly.
Above-mentioned triplet liquefied gas storage peculiar to vessel, wherein, the two ends of described left tank body, right tank body and upper tank body are respectively equipped with end socket.
Above-mentioned triplet liquefied gas storage peculiar to vessel, wherein, described end socket is semisphere or butterfly.
The technical scheme of triplet of the present utility model liquefied gas storage peculiar to vessel, breaches flow container volume design limit, and Selection and Design and the exploitation of having filled up domestic 3 ~ 100,000 cubes of liquefied gas carrier independence C type storage tanks are blank.The volume of triplet flow container of the present utility model compares the monomer flow container of same diameter and length or doublet flow container is compared, and improves about 90% and 15% respectively, thus can meet the flow container volume requirement day by day maximized in international liquefied gas carrier market.The cargo space degree of utilization of triplet flow container of the present utility model compares monomer flow container or the doublet flow container of same diameter and length, improve about 20% and 5% respectively, thus the flow container greatly saved under same volume and the material weight needed for surrounding hull cargo hold thereof and engineering cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 3 a to Fig. 3 e, a kind of triplet of the present utility model liquefied gas storage peculiar to vessel, comprise longitudinally crouch left tank body 1, right tank body 2 and upper tank body 3 in each cargo hold 4 of hull, wherein:
The two ends of left tank body 1, right tank body 2 and upper tank body 3 are respectively equipped with semisphere or butterfly end socket 4,5,6, in order to round and smooth smoothly closed tank;
Left tank body 1 and right tank body 2 are symmetrical arranged and are located at lower left quarter and the right lower quadrant of cargo hold 4 correspondingly, the lower right side of left tank body 1 and the left lower of right tank body 2 are close together and are isolated by a centerline bulkhead 9, make to have the space that is held upper tank body 3 between the right upper portion of left tank body 1 and the left upper portion of right tank body 2;
Upper tank body 3 be located at cargo hold 4 central upper and by the top of left tank body 1 and right tank body 2 upper between in the space that forms, the left side of this upper tank body 3 and the top of left tank body 1 are close together and are isolated with left tank body 1 by a left longitudinal bulkhead 7, the right side of this upper tank body 3 and the top of right tank body 2 are close together and are isolated with right tank body 2 by a right longitudinal bulkhead 8, left longitudinal bulkhead 7, right longitudinal bulkhead 8 and centerline bulkhead 12 form Y shape and are connected on cross-sectional plane, make left tank body 1, right tank body 2 and upper tank body 3 form isosceles triangle and arrange; Left longitudinal bulkhead 7, right longitudinal bulkhead 8 and centerline bulkhead 9 form Y shape and to be connected and at cargo hold 4 Medial Convergence on cross-sectional plane.
In a best embodiment, the shape of cross section C shape in abnormity identical with the shape of cross section of right tank body 2 of left tank body 1, the lower right side of left tank body 1 and the left lower of right tank body 2 are connected in the both side surface of centerline bulkhead 9 correspondingly, make the space that formed between the upper right quarter of left tank body 1 and the left upper portion of right tank body 2 V-shaped; The shape of cross section of upper tank body 3 is the fan-shaped of abnormity, and two sides of this upper tank body 3 on cross-sectional plane are connected to the upper surface of left longitudinal bulkhead 7 and the upper surface of right longitudinal bulkhead 8 correspondingly.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
