Domestic early stage dredger is the drag suction dredge from Japanese import before 30 years.This batch of ship adopts adjustable pitch propeller to advance.At present, because tenure of use is longer, marine main engine power drop, during rake suction operation, thrust is not enough.If change main frame, the investment of transformation axle system is huge, and the cycle is long.Therefore need to redress, extremely urgent.
And main reforming direction adopts this mature technology of shrouded propeller.Shrouded propeller is a sleeve on the peripheral equipment of conventional propeller, and the elevation profile of sleeve is airfoil type or knuckle line style, and this sleeve is just called conduit.When the principle of work of catheter propeller mainly relies on current to flow through conduit, the speed of current changes, and produces pressure reduction, makes conduit produce positive thrust, thus alleviates the load of screw propeller, raise the efficiency, improve the efficiency of heavy lift screw propeller.Use the benefit of catheter propeller except improving except propulsion coefficient, because catheter propeller can be optimized flow field, improve current, can make to act on pulsating pressure on catheter propeller and vibration all little than spacious water oar.But this technology is unsatisfactory for the support effect of this special ship class of dredger.Also rarely have the example of utilization, major cause is summed up as the particularity of dredger, requires the propulsive force larger than ordinary ships, and mud can affect the normal operation of screw propeller simultaneously.Therefore, the utility model is innovated on the basis of traditional shrouded propeller.
First, conduit 100 of the present utility model.Compared with traditional conduit, the structure of conduit 100 makes improvement, have a special guide margin 110 for circle and the outside plate 120 of S type.This appearance profile of conduit 100, makes the flow velocity of the current flow through around section higher, and does not produce separation, thus conduit 100 inside and outside differential pressure made becomes larger, produces larger thrust.We find in testing, and conduit 100 is greatly improved than the efficiency of conventional catheters, and concrete data are about and improve 4 ~ 6%.
In order to adapt to dredger, be provided with 24mm corrosion-resistant steel endless belt 130 in outside plate 120 inside, internal diameter 3.03m, length 1.5m.Lateral partitions 140 and fore and aft diaphragm 150 is provided with in outside plate 120 outside, lateral partitions 140 and fore and aft diaphragm 150 cross connection in length and breadth, in this enforcement, lateral partitions 140 has 3 roads, fore and aft diaphragm 15014 road, this design can the strength and stability of effective reinforced tube 100, and the ship being applicable to this high loss of dredger uses.
Consider restriction and the Joint strenght of locus, the connect box 400 of design conduit 100 and hull 600 adopts two box type constructions, arranges according to the angle of bracing strut.Outside plate 120 is connected with connect box 400 by rib position strong component 160.Connect box 400 comprises: cabinet shell 410, cross-tie plate 420, longitudinal reinforcer 430, flame diversion trough 440 and fixing inclined shaft 450, cabinet shell 410 upper end is connected with hull 600, cabinet shell 410 is internally connected with cross-tie plate 420 and longitudinal reinforcer 430, longitudinal reinforcer 430 is located on cross-tie plate 420, longitudinal reinforcer 430 is connected with cross-tie plate 420 is vertical, the side of cabinet shell 410 is connected with fixing inclined shaft 450, and fixing inclined shaft 450 is connected with hull 600.Although whole connect box 400 is casings, rectangular box, case body is very flat, simultaneously in order to reduce resistance, connects using narrower one side as front, improves the propulsive force of dredger.Cabinet shell 410 inside is also provided with cross-tie plate 420 and the longitudinal reinforcer 430 of criss-cross, and cross-tie plate 420 and longitudinal reinforcer 430, by being connected with mistake rib position strong component 160, strengthen the degree of being connected firmly of conduit 100 and connect box 400.
On the other hand, the utility model is still provided with flame diversion trough 440 at connect box 400, and flame diversion trough 440 is located at cabinet shell 410 two ends, and connect box is strengthening internuncial while, or dredger can be made to lose certain propulsive force, this and original intention run in the opposite direction, therefore, in order to make up this defect, we add flame diversion trough 440, flame diversion trough 440, due to the rectangular configuration of connect box 400, can't destroy overall balance, can increase the power of promoting comprehensively of dredger simultaneously.
Moreover be the structure of oar axle 240, blade 210 quantity in the present embodiment is 4, and blade 210 surface is provided with jog 211, and blade 210 is connected with one end of oar shell 230 by blade root 220, the other end of oar shell 230 is connected with oar axle 240, and oar axle 240 is connected with adapter shaft 300.
Last the utility model also improves deflecting plate, deflecting plate 500 comprises: plate body 510, deflecting plate attaching parts 520, upper drainage block 530 and lower drainage block 540, plate body 510 is connected with hull 600 by deflecting plate attaching parts 520, upper drainage block 530 and lower drainage block 540 are stream line pattern list structure, upper drainage block 530 and lower drainage block 540 are provided with through drainage trough 550, upper drainage block 530 is located at plate body 510 top, and lower drainage block 540 is located at plate body 510 bottom.The propulsive force of traditional deflecting plate to dredger has negative effect, very take installing space, but the most important transforms for this obsolete vessel, its line style and device are not considered to increase deflecting plate simultaneously, be often not mounting guiding board on dredger, or selectivity is installed.But deflecting plate about 500 of the present utility model is provided with drainage block 530 and lower drainage block 540 respectively, upper drainage block 530 and lower drainage block 540 are provided with through drainage trough 550, drainage trough 550 reduces the resistance of deflecting plate 500, effectively increases net thrust when dredging.
Be illustrated detailed description of the invention of the present utility model above, but the utility model is not as limit, only otherwise depart from aim of the present utility model, the utility model can also have various change.
