Description
Technical field
The present invention relates to a kind of spray deflector, specifically a kind of double-deck spray deflector knot being arranged on high-speed catamaran
Structure.
Background technique
Currently, not installing spray deflector on conventional high rate ship or only installing a horizontal spray deflector, ship is in high-speed aircraft
Foremost part of ship is raised when row, and ship stern settlement, stem will form water jets under high pressure, and when water column is impacted to hull structural member, water column is opened
Flower, conventional high rate ship may cause not in time spray of water to driver's cabin front glass because of draining at this time, influence to drive, more seriously
When shipping of green water, cause hatch to be intake, influence accommodation under deck.
Summary of the invention
According to technical problem set forth above, and provide a kind of double-deck spray deflector structure being arranged on high-speed catamaran.
The technological means that the present invention uses is as follows:
A kind of double-deck spray deflector structure being arranged on high-speed catamaran, two including being separately positioned on high-speed catamaran
The spray deflector I of the two sides of hull, the spray deflector I from the chine of the stem front end of the high-speed catamaran body backward under
Fang Yanshen, and the length of the spray deflector I be the high-speed catamaran body length 12%-17%, the spray deflector I with it is described
The angle of the baseline of high-speed catamaran is 4 °~6 °, and the lower surface of the spray deflector I is parallel to the base of the high-speed catamaran
Line；
Spray deflector II is equipped on the outside of two hulls of the high-speed catamaran, and the spray deflector II is arranged described
The top of spray deflector I, and the spray deflector II is parallel to the spray deflector I, the spray deflector II is from the high-speed catamaran body
Stem front end be arranged backward, and the length of the spray deflector II be the high-speed catamaran body length 8%~12%, institute
State ship outer casing of the lower surface perpendicular to the high-speed catamaran of spray deflector II.
The lower section of the spray deflector I is equipped with the bracket to match with the length of the spray deflector I, the bracket it is following with
The shell of the high-speed catamaran is fixedly connected, and the angle between the bracket and the shell of the high-speed catamaran is 45 °,
It is fixedly connected in the middle part of the top of the bracket and the lower surface of the spray deflector I.
The shell of the bracket and the high speed catamaran hull is fixedly connected by the way of welded corner joint, the bracket with
It is also fixedly connected by the way of welded corner joint in the middle part of the lower surface of the spray deflector I.
The integral structure that the spray deflector I is formed by upper plate I and lower plate I, the side of the lower plate I and the high speed binary
The shell of ship is fixedly connected, and the lower plate I is parallel to the baseline of the high-speed catamaran, the side of the upper plate I with it is described
The shell of high speed hull ship is fixedly connected, and the other side of the upper plate I is intersected and is fixedly connected with the other side of the lower plate I,
And the upper plate I and the inner surface of I fixed connection place of lower plate have fillet, the upper plate I is fixedly connected with the lower plate I
Outer surface be wedge angle；
The integral structure that the spray deflector II is formed by upper plate II and lower plate II, the side of the lower plate II and the high speed
The shell of catamaran is fixedly connected, and the lower plate II is perpendicular to the shell of the high speed catamaran hull, the side of the upper plate II
It is fixedly connected with the shell of the high speed hull ship, the other side of the upper plate II is intersected and consolidated with the other side of the lower plate II
Fixed connection, and the upper plate II and the inner surface of II fixed connection place of lower plate have a fillet, the upper plate II with it is described under
The outer surface that plate II is fixedly connected is wedge angle.
The shell bearing and the lower plate I of the upper plate I and the high-speed catamaran are outer with the high speed catamaran hull
The distance between shell bearing is 150mm~200mm；The shell bearing of the upper plate II and the high-speed catamaran and described
The distance between shell bearing of lower plate II and the high speed catamaran hull is 70mm~150mm.
Stating the difference in height between spray deflector I and the spray deflector II is 800mm~1200mm.
The present invention obtains ship by installing two groups of spray deflectors (i.e. spray deflector I and spray deflector II) in high-speed catamaran
Better drag-reduction effect and rolling performance, spray deflector I and horizontal plane form the stem that a low-angle inclination angle can make and form spray
When splashing, the water in spray deflector I can be quickly discharged.The length of spray deflector I and spray deflector II selected by the present invention can prevent too short
Spray deflector length inhibit fore body splashing effect it is unobvious, too long spray deflector length may result in heave and trim is excessive
The problems such as.It is turned round when after horizontal spray deflector is installed along chine, being advantageous to resistance and rolling performance, but grasping small rudder angle
Angle of Heel is larger, brings adverse effect to steering.If horizontal spray deflector is changed to vertical spray deflector, turning round heel can be obtained
To improvement appropriate, but the real ship speed of a ship or plane can lose, and the rolling performance in stormy waves also wants difference.Therefore horizontal spray deflector is used
The mode (i.e. spray deflector I and spray deflector II) combined with vertical spray deflector will not lose the speed of a ship or plane and rolling when splashing smaller
Performance can also obtain smaller angle of banking when splashing larger, reduce the operational danger in stormy waves.
The present invention can be widely popularized in fields such as spray deflectors based on the above reasons.
