Abstract
The utility model discloses a draft-adaptable vertical bulbous bow of a tanker. The bulbous bow is positioned at the bottom of a stem, and a groove is reserved at the joint of the stem and the bulbous bow, extends from the front end of the stem to a hull. Through the groove, the stem and the bulbous bow are in smooth transition, and a keel line at the front end of the bulbous bow and the front end of the stem is similar to a straight line. The draft-adaptable vertical bulbous bow of the tanker can effectively reduce resistance in running of the tanker.
Description
Technical field
The utility model relates generally to the shipbuilding field, especially relates to the suitable drinking water of a kind of oil carrier erect type ball first.
Background technology
Now, ships that transport extensively adopts the first line style of ball.On energy-saving principle, it has been generally acknowledged that, for middle low powered, the expection ball is first to form the favourable interference of wave making with main body, thereby reduces the wave making resistance of boats and ships, and in addition for some full formed ship, ball head also can reduce its bilge whirlpool.
In the prior art, the first ball head that protrudes first post for front end of the ball that most of boats and ships adopt, it is the ball head of one " S " type from the side, the resistance reducing performance of this kind ball head is often relatively responsive for drinking water.Because carrier usually has the operation demand of multiple drinking water state, normally design for a certain drinking water of being concerned about most, to reach more excellent resistance performance, take into account simultaneously the performance of other drinking water as far as possible, and this difficult point place of the first design of ball often.
The utility model content
Problem for above-mentioned existence, the purpose of this utility model is to provide the suitable drinking water of a kind of oil carrier erect type ball first, utilize the ball of this type first, can adapt to preferably the operation demand of multiple drinking water state, thereby can effectively reduce the fuel oil consumption of boats and ships in the whole operation cycle.
Specifically be achieved through the following technical solutions:
The suitable drinking water of a kind of oil carrier erect type ball is first, and described ball first place is in the bottom of bow, wherein, the junction of described bow and described ball head is a groove, described groove extends to hull from the front end of described bow, by described groove, forms between described bow and the described ball head and seamlessly transits; The keel line of the first front end of described ball and described bow front end is similar to linearity.
The suitable drinking water of above-mentioned oil carrier erect type ball is first, and wherein, described groove is a shallow ridges type groove.
The suitable drinking water of above-mentioned oil carrier erect type ball is first, and wherein, the described groove that is positioned at described hull place is similar to linearity.
The suitable drinking water of above-mentioned oil carrier erect type ball is first, and wherein, described ball head is a level and smooth cambered surface.
By above-described the technical solution of the utility model, compared with prior art, the utlity model has following technique effect:
The suitable drinking water of a kind of oil carrier of the present utility model erect type ball is first, by a shallow ridges type groove is set between bow and ball head, the bow of the first post of the protrusion compared to existing technology, the resistance performance of this erect type ball head is less sensitive for the difference drinking water, thereby can better adapt to the operation demand of multiple drinking water state.Simultaneously, first with respect to conventional ball, this erect type ball head has been equivalent to increase the length of design load water line, has reduced near the angle of attack of the waterline of designed draft, and this also is conducive to reduce wave making resistance and the form resistance of boats and ships.
Those skilled in the art reads the detailed description of following preferred embodiment, and with reference to after the accompanying drawing, the advantage of these and other aspects of the present utility model undoubtedly will be apparent.
Description of drawings
Fig. 1 is the structural representation of the suitable drinking water of a kind of oil carrier of the present utility model erect type ball head.
Fig. 2 is the schematic diagram at another visual angle of the suitable drinking water of a kind of oil carrier of the present utility model erect type ball head.
Fig. 3 is the again schematic diagram at a visual angle of the suitable drinking water of a kind of oil carrier of the present utility model erect type ball head.
The specific embodiment
With reference to appended accompanying drawing, describing more fully embodiment of the present utility model, yet appended accompanying drawing only is used for explanation and sets forth, and does not consist of the restriction to the utility model scope.
The embodiment main process of the suitable drinking water of a kind of oil carrier of the utility model erect type ball head is:
In conjunction with shown in Fig. 1 to 3, the suitable drinking water of a kind of oil carrier erect type ball is first, this ball head 1 is positioned at the bottom of bow 2, wherein, bow 2 is a groove 3 with the junction of ball head 1, and groove 3 is a shallow ridges type groove, and this groove 3 extends to hull 4 from the front end of bow 2,, be positioned at first 1 front end of ball on the keel line 21 and the front end of bow 2 and be always linear structure so that form between bow 1 and the ball head 2 and seamlessly transit by groove 3.
In a specific embodiment of the present utility model, this groove 3 is positioned at curvature on the keel line 21 of bow 2 close to zero, the part that this groove 3 is positioned at these keel line 21 both sides caves inward slightly, and simultaneously, the part that is positioned at the groove 3 at hull 4 places is similar to linearity.
In addition, ball head 1 is a level and smooth cambered surface.
In the utility model by the groove 3 of a shallow ridges type is set between bow and ball head, particularly, the curvature of this groove 3 on keel line is almost close to zero, so that the ball on the keel line 21 first 1 and the bow line on it are close to a level and smooth straight line, project organization by this groove 3, boats and ships under steam, current from the part of the groove 3 of the front end that is positioned at ship and along groove 3 with the water water conservancy diversion to hull bottom.The resistance performance of this erect type ball head is less sensitive for the difference drinking water, thereby can better adapt to the operation demand of multiple drinking water state.Simultaneously, first with respect to conventional ball, this erect type ball head has been equivalent to increase the length of design load water line, has reduced near the angle of attack of the waterline of designed draft, and this also is conducive to reduce wave making resistance and the form resistance of boats and ships.
By specification sheets and accompanying drawing, provided the exemplary embodiments of the ad hoc structure of the specific embodiment, therefore, although above-mentioned utility model has proposed existing preferred embodiment, yet these contents are not as limitation.For a person skilled in the art, read above-mentioned explanation after, various changes and modifications undoubtedly will be apparent.Therefore, appending claims should be regarded whole variations and the correction of containing true intention of the present utility model and scope as, and any and all scope of equal value and contents all should be thought still to belong in intention of the present utility model and the scope in claims scope.
