Technical field
The present invention relates to technical field of ships, and in particular to it is a kind of with follow-up steering and stablize auxiliary system water spray push away
Into ships and light boats, efficiency and stability when can assist improving the navigation of hydraulic jet propulsion ships and light boats and turning to, moreover it is possible to exist to hydraulic jet propulsion system
Part other than hull plays a protective role.
Background technology
Current hydraulic jet propulsion ships and light boats have the characteristics that manipulation is flexible and power output efficiency is high, and being that one kind is advanced pushes away
Into system ships and light boats.Because hydraulic jet propulsion system is usually mounted on the tailgate of hull, hull bottom need not be placed in hereinafter, also having
Having can be the advantages of shallow water area be navigated by water.
Current hydraulic jet propulsion ships and light boats, hydraulic jet propulsion system are typically mounted on the tailgate portion of ships and light boats, water jet and commutation
Usually because moving backward or being turned in barrier zone, damage caused by with the collision of hard object occurs for air deflector.Commonly solution is
The placement stainless steel protection device of the portion other than hull or addition stern diving platform etc. are protruded from hydraulic jet propulsion system
Protrusion is protected, the disadvantage is that sacrifice hull it is overall beautiful, increase aft weight.
Current hydraulic jet propulsion ships and light boats steering operation, merely by changing the direction realization of water jet jet flow, but due to spray
The thrust vectoring degree of water propeller is relatively low, is particularly easy to lose navigating by water steering thrust when turning to.
The thrust of hydraulic jet propulsion ships and light boats is sucked after flow to spray and be generated by hydraulic jet propulsion system, the pipeline of hydraulic jet propulsion system
Middle sucked water body weight can cause the displacement of hull tail portion to increase（Usually account for 5% or so of full marine railway water）Make ships and light boats
Stern settlement reduces the navigation effect of ships and light boats since the increase of tail portion draining also brings the increase of ships and light boats tail portion wave making resistance
Rate and stability.
Invention content
The technical problem to be solved by the present invention is to：There is provided it is a kind of with follow-up steering and stablize auxiliary system water spray push away
Into ships and light boats, while so that part of the hydraulic jet propulsion system of hydraulic jet propulsion ships and light boats outside prominent hull is adequately protected, moreover it is possible to
The stability when wave making resistance of ships and light boats and the navigation of service hoisting hydraulic jet propulsion ships and light boats and steering is answered, reduced to the steerage of raising ships and light boats
And efficiency.
To achieve the above object, the technical solution adopted in the present invention is:One kind is with follow-up steering and stablizes auxiliary system
The hydraulic jet propulsion ships and light boats of system include hull platform with hydraulic jet propulsion system, tail portion fixed appendage, the attached body of follow-up steering, biography
Lever, synchronising (connecting) rod, the tail portion fixed appendage is using hollow body filling expanded material or by other materials with buoyancy
It is made, is fixed on the hull tail portion of the hull platform underwater with hydraulic jet propulsion system, bottom faces form is that hull is flat
The continuity of platform hull bottom face molded line, side of a ship side form are the continuities of the side of a ship side molded line of hull platform underwater, can so be risen
To the effect for extending hull Water Plane length, wave making resistance of the ships and light boats in navigation, the attached body connection of the follow-up steering are reduced
In the rotation axis of tail portion fixed appendage, bottom is equipped with fair water fin, can improve the flow field of ships and light boats tail portion, reduces viscous pressure resistance,
The stability of ships and light boats is improved, the attached body of follow-up steering is connect by drive link with synchronising (connecting) rod, and the synchronising (connecting) rod is pushed away with water spray
Water jet steer-drive into device connects, and when water jet steer-drive control water jet turns to, follow-up steering is attached
Body keeps rotating synchronously with water jet, and be conducive to ships and light boats reduces lateral resistance when turning to, and is located at the attached body bottom of follow-up steering
The steerage that fair water fin generates is answered, and assisted diversion is played the role of.
