Abstract
The present invention is a kind of device that is combined into one that ships and light boats are advanced and handle.It utilizes the pump of propulsive units to form jet water course generation thrust, utilize the rotation of rudder shell and rudder blade or closure to reflect again or reflect jet flow and form steerage or inverted navigation thrust, just can not make ships and light boats system stop or fall to navigate so need main frame to reverse, and make boats and ships under various boat attitudes, all have good maneuvering performance.It can obtain to be better than the efficient of routine propelling when being used for ships and light boats that heavy load advances.It is specially adapted to the ships and light boats of shallow draft waterway, makes it significantly reduce shallow water effect, to reduce resistance, improves propulsion coefficient.
Description
The present invention is a kind of waterjet propulsion and operating control of ships and light boats.
Current waterjet propulsion ships and light boats, it is handled and propelling unit is discrete, and spout does not have the rectification leaf, and the rudder shell does not rotate, and propulsion coefficient is low.
Task of the present invention is that propelling and manipulation are combined into one, and improves propulsion coefficient, improves maneuvering performance, reduces the influence of shallow water effect.
The present invention promptly is made up of water jet propulsion pump and rudder gear two parts and hangs on hull (see figure 1) outward by advancing and handling.
Propulsive units by custom-designed pump case 1., preposition support 2., 4. axial-flow type or the diagonal flow type pump wheel spout that 3. reaches band rectification leaf form.Its function is to produce thrust by main engine power output shaft impeller to form jet water course.Actuating element by the rudder shell 5., 7. 6. rudder blade form with splitter.Its function is to rotate when handling or the closed relatively runner that forms refraction or reflection jet flow, controls thrust direction to handle boats and ships.
It is lower and require the boats and ships of the bigger heavy load propulsion quality of thrust that the present invention is particularly suitable for shallow draft boats and ships and the speed of a ship or plane, can obtain higher propulsion coefficient.On handling, the invention belongs to the active rudder pattern, so can significantly improve the road-holding property of boats and ships under various boat attitudes and can reach cast.
Implement technical essential of the present invention and the applied in any combination situation is as follows:
1, propulsive units
11 utilize custom-designed pump case to improve the influent stream condition of impeller, impeller is operated in the flow field far beyond conventional screw propeller expansion, thereby improves its water effect rate;
12 owing to the interface of pump case as the deadening internal and external flow field, the punching press that forms when enabling to utilize ship's navigation, improved the cavity performance of impeller, thus can be the transformation of energy that little blade is finished same mechanical water merit with more conventional screw propeller disc area, thus raise the efficiency;
13 when being used for multiaxis propelling ship time, and the pump shaft support as preceding stator, is saved Shears, reduced appendage drag, can also give whole current, improves the impeller work flow field;
The stator at 14 spout places can be led the circumferential induction velocity of wake flow behind the impeller directly, thereby recuperated energy is used for advancing, and has improved propulsion coefficient;
15 specially designed aerofoil profile pump cases have the function that is similar to conventional mozzle, thus can increase thrust, and differ from conventional water jet propulsion pump, and pressure loss in duct is reduced, can increase propulsion coefficient.
2. when this pattern of actuating element rudder type A-mainly advances for single shaft and the propulsive units use (Fig. 2) that forms a complete set of.
21 utilization hydraulic pressure hollow sleeves handle respectively two halves rudder shell 5. with rudder blade 6., when the two synchronous or asynchronous left, when starboard rotates, the steerage when producing the positive car navigation of boats and ships then;
The 22 two halves rudder shells with aerofoil profile rotate relatively until closure, satisfy and behind spout, form the reflection runner, this moment, jet flow reflected to form the boats and ships astern thrust and main frame does not still reverse, and turned left and right the manipulation purpose that then reaches when navigating synchronously as the rudder shell of closure and rudder blade face;
7. 23 rudder shells are provided with splitter, and it separates jet flow and contrajet, reduces the two phase mutual interference, thereby improve astern thrust;
24 stream line pattern rudder blades are in order to improving little rudder angle steerage, the overbalance torque that balanced rotation rudder shell is excessive, and when reversing in order to separate the contrajet on both sides, reduce water impact and eddy loss;
Have the oblique through flow hole of intersection on 25 rudder blades, its pore size, quantity and degree of dip thereof change with the watt level of water jet propulsion pump, are beneficial to the formation of contrajet, and increase through-current capability when the reversing steering;
26 when the rudder shell from standard-sized sheet gradually to full cut-off, then the thrust that causes of jet flow infinitely carries out the transition to the reversing maxim and main frame does not need speed change and reverse from positive car maxim, but the steerage of handling does not weaken yet, so easily reach the good result of cabin hormany operating;
The present invention and other various types of seemingly functional device relatively have following good result:
1. propelling of the present invention and handle effect and can add rudder, voith schneider propeller with existing tuning for Controllable Pitch Propeller, circle round catheter propeller etc. quite entirely, but in simple in structure, the unique advantages in aspect such as parts are few, cost is low, easy to maintenance, manoeuvrable;
2. the present invention all works in higher jet speed at any boat attitude of boats and ships lower rudder shell and rudder blade, and higher steerage is provided, and this will be better than such as existing various efficient manipulation devices such as rotation diversion tube, flap, active rudder;
3. the present invention is used for shallow water and heavily advances the ship of loading, cause has concurrently and reclaims the wake flow rotating energy, pump case provides additional thrust, rudder shell to increase characteristics such as work done water flow, smaller conduit loss, so will be better than catheter propeller, conventional waterjet propulsion and other energy-conservation propelling unit on efficient;
4. when the present invention works in shallow water because pump case and rudder shell have been separated the meiobar that the inner high speed current cause, cause backward dip to reduce, guaranteeing under the import water yield, thrust reduces very little, so make boats and ships seldom in the shallow water effect that is subjected to aspect resistance and the propelling, this be other various propelling units can't be obtained.
