Description
Technical field
The utility model relates to a kind of boats and ships, relates in particular to a kind of streamlined reefer housing that is arranged on boats and ships bow top.
Background technology
Along with manifesting gradually of world energy sources crisis, international oil price is always in concussion rise state since entering 21 century, and this makes shipping cost high, therefore cuts operating costs and becomes the common problem of shipbuilding industry.And meanwhile, because the various environmental problems that greenhouse gas emission causes are increasingly serious, and be subject to the extensive concern of international community.Along with EEDI is about to enforce, green ship concept is rooted in the hearts of the people, although air draught only accounts for a seldom part of boats and ships total drag, if adopt good fairing, can obtain good energy-saving effect, the energy saver that exploitation reduces boats and ships air draught also becomes focus.
Utility model content
The purpose of this utility model is to solve the problems of the prior art, provides a kind of and reduce ship superstructure resistance, has the ship superstructure drag reduction streamlined reefer housing of effects of energy saving and emission reduction.
The technical solution of the utility model is: a kind of ship superstructure drag reduction streamlined reefer housing, and this streamlined reefer housing is mainly by Guide flow, right side flow deflector and middle flow deflector is one-body molded forms; The both sides of flow deflector in the middle of described Guide flow, right side flow deflector are symmetricly set on; The space that described Guide flow, right side flow deflector and middle flow deflector form is hollow cavity; Described Guide flow, the front end of right side flow deflector and the front end of middle flow deflector converge at a bit, and open opening with this point to its tail end formation one.
Preferably, described Guide flow, right side flow deflector all curve inwardly curved.
Preferably, described middle streamlined reefer housing is bent downwardly curved.
Preferably, the height of the distance horizontal surface of described Guide flow, right side flow deflector and middle flow deflector is 18～25m.
Preferably, the height of the distance horizontal surface of described Guide flow, right side flow deflector and middle flow deflector is 20.3m.
Preferably, the length of described middle flow deflector is 35～50m.
Preferably, the length of described middle flow deflector is 42m.
The utility model relates to and is generally arranged on boats and ships bow, is knuckle streamlined structure, and this device has the Flow Field of improvement, thereby reduces ship superstructure air draught, has good energy-saving effect.
Brief description of the drawings
Fig. 1 is installation block diagram of the present utility model;
Fig. 2 is the front elevation of installing and using of the present utility model;
Fig. 3 is the birds-eye view of installing and using of the present utility model.
Detailed description of the invention
For technological means, technical characterictic, utility model object and technique effect that the utility model is realized are easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of ship superstructure drag reduction streamlined reefer housing, this streamlined reefer housing 100 is mainly by Guide flow 101, right side flow deflector 102 and middle flow deflector 103 is one-body molded forms; The both sides of flow deflector 103 in the middle of described Guide flow 101, right side flow deflector 102 are symmetricly set on.
Guide flow 101, right side flow deflector 102 are hollow cavity with the space that middle flow deflector 103 forms; The front end of Guide flow 101, right side flow deflector 102 and the front end of middle flow deflector converge at 1: 104, and extend to form one with this point 104 to its tail end and open opening.
Guide flow 101 of the present utility model, right side flow deflector 102 all curve inwardly curved, for knuckle stream line pattern, have utilized aerodynamic principle, reduce building air draught, and middle streamlined reefer housing 103 of the present utility model is bent downwardly curved.Guide flow 101, right side flow deflector 102 are 18～25m with the height of the distance horizontal surface of middle flow deflector 103, are preferably 20.3m.The length of middle flow deflector 103 is 35～50m, is preferably 42m.
The following is 9000 casees freight containers, 200 ship hull principal parameters, as shown in table 1.
Table 1
Referring to Fig. 2,3 known, stem streamlined reefer housing 100 is installed on promenade deck, and streamlined reefer housing 100 is knuckle stream line pattern, highly being equal to the height of freight container 200, is 20.3m, and length is 42m, be installed on the region of upper deck boats and ships 201 bows to freight container 200 front ends, approximately 30 ° of horizontal sextant angles.
The utility model relates to and is generally arranged on boats and ships 201 bows, is knuckle streamlined structure, and this device has the Flow Field of improvement, thereby reduces ship superstructure air draught, has good energy-saving effect, generally can reach 2%～4% energy-saving effect.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
