Abstract
The utility model discloses a small waterplane area catamaran hull with a plurality of communication type stabilization fins, which comprises an upper deck, wherein the lower part of the upper deck is provided with two demi bodies which are placed in parallel, the demi body is composed of a support post and submergence bodies, the support post is a plate-shaped structure, the upper part is fixedly connected with both sides of the lower surface of the upper deck, the lower rim is welded on the outer side surface of the submergence body along longitudinal direction of the submergence body and the stabilization fins are arranged on the submergence bodies. The utility model is characterized in that the stabilization fins are communication type stabilization fins, and at least three stabilization fins are arranged. The three stabilization fins are perpendicular to the submergence bodies and are uniformly distributed between the two submergence bodies along the longitudinal direction of the hull, and both ends are respectively fixedly connected with the two submergence bodies. The small waterplane area catamaran hull has the advantages that the force lifting performance is good, the heave damping coefficient is large, the fluctuation height of heave of the hull can be reduced, crew are not easily seasick, and the utility model is good to the crew's health.
Description
(1) technical field
The utility model relates to a kind of boats and ships.Be the small waterplane area twin hull ship (SWATH) hull that has a plurality of communication type stabilizing fins specifically.
(2) background technology
Small waterplane area twin hull ship (SWATH) is widely used on military and civilian for a long time as a kind of High Performance draining boats and ships.Because small waterplane area twin hull ship (SWATH) under sail, submerged body is subjected to " Munch moment " effect under two, can produce the instability problem of longitudinal movement.For this reason, two down the inboard, two ends of submerged body respectively be equipped with a stabilizing fin be its head and the tail each is a pair of, to be used to improve the stability of small waterplane area twin hull ship (SWATH) longitudinal movement.Both sides, stabilizing fin front and back wherein are trapezoidal, and when navigation, its end can form eddy current, thereby makes loss of lift.In addition and since this stabilizing fin along beam direction weak point to be that its exhibition is grown less, less along the length ratio of captain's direction and Width is that aspect ratio is less, also can reduce the lift coefficient of stabilizing fin.Therefore, use the small waterplane area twin hull ship (SWATH) hull of this stabilizing fin, the lift poor-performing.
Again because the lift poor-performing, it is less to make that hull vertical swings damping coefficient, and height of heave is bigger up and down, easily makes the occupant seasick, healthy unfavorable to the occupant.
(3) content of utility model
The technical problems to be solved in the utility model provides a kind of small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has.This small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has, the lift performance is good, hang down that it is big to swing damping coefficient, can reduce the height of heave up and down of hull, and it is seasick that the occupant is difficult for, and helps occupant's health.
For addressing the above problem, the utility model is taked following technical scheme:
The small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has of the present utility model comprises upper deck, and upper deck below has two to be and to be arranged in parallel, and this lamellar body is made up of pillar and following submerged body.Said pillar is a platy structure, and its top is connected mutually with the lower surface both sides of upper deck, and submerged body vertically is welded on the external side of dive under its lower edge.On the following submerged body stabilizing fin is arranged, be characterized in that said stabilizing fin is the communication type stabilizing fin, this communication type stabilizing fin has three at least, they and following submerged body is perpendicular and vertically be distributed between two following submerged bodies along hull, their two ends are connected mutually with twice submerged bodies respectively.
Take such scheme, have the following advantages:
Because the small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has of the present utility model, its stabilizing fin is the communication type stabilizing fin, and long ratio of exhibition and aspect ratio are all quite big, have eliminated the loss of lift that traditional stabilizing fin end eddy current causes, have improved the lift coefficient of stabilizing fin.Therefore, use this small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has, can improve the lift performance of hull greatly.
Because the lift performance is good, make the vertical damping coefficient that swings of hull improve greatly again, height of heave reduces up and down, has effectively improved vertical swing and pitching motion of hull in wave, has avoided the occupant seasick, helps the healthy of occupant.
(4) description of drawings
Fig. 1 is the small waterplane area twin hull ship (SWATH) hull scheme drawing that is communicated with fin that has of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
(5) specific embodiment
As shown in Figure 1 and Figure 2, the small waterplane area twin hull ship (SWATH) hull that is communicated with fin that has of the present utility model comprises upper deck 1, and upper deck 1 below is provided with two lamellar bodies.These two lamellar bodies parallel, and they are formed by pillar 2 and following submerged body 3.Said pillar is a platy structure, and its top is connected mutually with the lower surface both sides of upper deck 1, and submerged body 3 vertically is welded on down on submerged body 3 lateral surfaces under its lower edge.Be provided with three stabilizing fins 4 between two following submerged bodies, these three stabilizing fins 4 are the communication type stabilizing fin, they vertically and following submerged body 3 is perpendicular and vertically be evenly arranged between two following submerged bodies 3 along hull, their two ends respectively with the lateral surface weld together of twice submerged bodies 3.
Said communication type stabilizing fin is a flats, and in its vertical both sides: a limit is thin, and a limit is thick, and is linear transition between both sides.
Claims (2)
1. have the small waterplane area twin hull ship (SWATH) hull that is communicated with fin, comprise upper deck (1), upper deck (1) below has two to be the lamellar body that is arranged in parallel; This lamellar body is made up of pillar (2) and following submerged body (3); Said pillar is a platy structure, and its top is connected mutually with the lower surface both sides of upper deck (1), vertically being welded on down on submerged body (3) lateral surface of submerged body under its lower edge (3); Stabilizing fin (4) is arranged on the following submerged body, it is characterized in that said stabilizing fin (4) is the communication type stabilizing fin, this communication type stabilizing fin has three at least, they vertically and following submerged body (3) is perpendicular and vertically be distributed between two following submerged bodies (3) along hull, their two ends are connected mutually with twice submerged bodies (3) respectively.
