Description

Unrestrained guiding device that divides of unrestrained on bow is prevented

Technical Field

The application relates to the technical field of catamarans, in particular to a bow wave-rising-preventing water diversion device.

Background

The catamaran is a ship formed by connecting the upper parts of two separated underwater hulls into a whole by using a reinforcing framework, wherein a strong framework for connecting the two hulls is called a connecting bridge, and a plurality of cabins are arranged on the strong framework; the catamaran has the advantages of good stability, safety, comfort, flexible operation and the like, and is often used as a medium-sized passenger ship, a small-sized passenger ship and a ferry.

But the catamaran also has the swing cycle short, and the weak shortcoming of midbody structure causes the ship draught to be relatively darker because small-size marine catamaran ubiquitous type is dark big enough and in addition be the reason of little waterline face boats and ships, and the height that forms between two hulls and the connecting bridge is lower, therefore easily receives the surge and slamming towards the hull that sets up on the connecting bridge, causes the hull to jolt from top to bottom, the operation unstable, even causes certain harm to the hull in serious time, has certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

Optionally, one side of the connecting bridge facing the bow direction is provided with a first inclined surface for guiding swell waves to move towards the wave dividing plate.

By adopting the technical scheme, one side of the connecting bridge facing the bow is set to be the first inclined plane, when the surge surges towards the bow, under the action of the first inclined plane, the acting force of the upward part in the surge is divided into two acting forces, one of the two acting forces faces upwards, and the other acting force faces the horizontal direction, so that the upward bumping acting force at the bow is further reduced.

Optionally, the connecting bridge is further provided with a guide plate for guiding surge which flows in towards the bow to each diversion channel, the guide plate is arranged in a pointed manner towards the bow direction and is fixedly arranged on the side surface of the diversion plate facing towards the bow, and the pointed side of the guide plate and the diversion plate are arranged to be curved surface connection surfaces through arc-shaped steel plates.

By adopting the technical scheme, when the surge flows towards the bow, the flow guide plate arranged at the tip cuts the surge in advance through the tip, and the diverted surge is guided into each diversion channel through the curved surface arrangement, so that the resistance of the ship body and the diversion plate in the surge diversion process is reduced.

Optionally, the cross-sectional area of the passage from the bow to the middle of the hull decreases progressively.

Through adopting above-mentioned technical scheme, set up progressively steadily from the cross-sectional area of bow to hull middle part passageway through the connecting bridge, indirectly changed the circulation cross-sectional area that the flow direction hull was shoved for the velocity of flow of surging when through the middle part passageway increases, makes the rapid through hull of surging, and indirect reduction is shoved and is slammed the number of times to the hull.

Optionally, the side of the connecting bridge facing away from the bow is arranged to be used for guiding surge flowing from the stern to the second inclined plane below the connecting bridge.

By adopting the technical scheme, the second inclined plane can divide the acting force of the upward part of the surge rushing from the stern into an upward acting force and a horizontal acting force so as to further reduce the upward bumping acting force on the bow.

Optionally, the side of the wave dividing plate facing away from the bow is provided with a third inclined surface for reducing impact force generated when surge from the stern is guided to the lower part of the connecting bridge.

By adopting the technical scheme, the third inclined plane can weaken the acting force of the horizontal part in the surge gushing from the stern, and the flow distribution plate is protected.

Optionally, the connecting bridge, the wave dividing plate, the inclined block and the guide plate are welded into a whole through steel plates.

Through adopting above-mentioned technical scheme, connect bridge, wave dividing board, slope piece and guide plate and all weld as an organic wholely through the steel sheet, through integral compact setting, improved overall structure's attack resistance ability.

In summary, the present application at least includes the following beneficial technical effects:

1. the diversion plate and the diversion plate are arranged on the connecting bridge, and the diversion and guide structures are formed by utilizing curved surfaces among the diversion plate and the diversion plate, so that the surge from the bow of the ship firstly primarily shunts through the diversion plate and then enters the diversion channels on the two sides of the diversion plate, the slamming effect of the surge direction is reduced through the arched channels, and the jolt of the ship body is reduced;

2. through all being the inclined plane setting in bow, stern direction at the connecting bridge for no matter when surging in the bow or stern direction, can both play the effect that reduces surge and slam the ship body.
