Abstract
Arrangement for propulsion of seaborne vessels, especially high speed boats, wherein a paddle wheel (1) is fitted in a closed pump house (11) and acts like a waterjet impeller. Pump house and paddle wheel are formed to make the system act like a pump, according to a combination of the centrifugal and the displacement principle. The propulsive efficiency can be optimised by controlling the vacuum in the pump house (11) with an air valve. Steering is done by small rudders in the water outlet (4), changing direction of the water flow through the outlet (4). Reversing is done by reversing ducts (6) similar to the systems on ordinary waterjets.
Description
Invention field
The present invention relates to a kind of novel hydro-jet propulsion system that is used for high speed vessel.
The prior art situation
Existing hydro-jet propulsion system comprises various screw propellers (fixed pitch or variable-pitch), blade face perforate screw propeller, waterjet propulsor and air screw.
Blade face perforate screw propeller and air screw have good propulsion coefficient when high speed, but often at low speed timeliness rate variance, and maneuvering performance is poor.Perforate screw propeller in blade face also often has the defective of vibration problem.
The speed of common screw propeller (particularly controllable pitch propeller) below about 40 joints has good propulsion coefficient.They do not use more than 40 joints usually.
It is more reliable that waterjet propulsor and screw propeller are compared with blade face perforate screw propeller, and do not have any vibration problem.The propulsion coefficient specific leaf area perforate screw propeller of waterjet propulsor when high speed is low, but they have higher propulsion coefficient and maneuvering ability usually when low speed.
Above-mentioned all propulsion systems all have following shortcoming, i.e. its rotation is all 90 degree with respect to current.
The applicant understands Norwegian Patent numbers 913921, WO93/08075 and British Patent No. 1090062.These systems all adopt with paddle wheel that rotates with the current equidirectional and so on.
Overview of the present invention
Waterjet propulsor of the present invention also adopts with the paddle wheel that rotates with the current equidirectional, but this paddle wheel is installed in the pump chamber of closing, and its effect is equivalent to an impeller.This is equivalent to a waterjet propulsor with regard to the effect that makes system, and is different from the situation of aforementioned system.
Adopt waterjet propulsor of the present invention, the propulsion coefficient in the time of can being implemented in high speed is similar or better to blade face perforate screw propeller, compares with present waterjet propulsor when being implemented in low speed simultaneously to have similar or better reliability, road-holding property and propulsion coefficient.
Present system, its problem just are to be difficult to keep a very high propulsion coefficient in a very big speed range.Paddle wheel of the present invention with and current equidirectional this fact of rotating make the relative motion between water and the paddle wheel all roughly remain constant at all speed places.This just can keep a very high propulsion coefficient in a very big speed range.
The present invention adopts pack into a fully enclosed pump chamber and it is realized this target as an impeller of paddle wheel.Because this configuration of paddle wheel, will increase pressure and speed by pump chamber for current.
Direction control is similar to present waterjet propulsor, can realize by the direction that adopts yaw rudder to change current in the outlet.
Then the waterjet propulsor with general is the same in reversing, can be undertaken by adopting reverse pipeline.
By following description and in conjunction with the accompanying drawings and appended claims, will be further understood that advantage of the present invention and characteristics.
Brief Description Of Drawings
Fig. 1,2 and 3 illustrates an especially configuration as just representational embodiment that is used to advance the waterjet propulsor of high speed vessel of the present invention.
Fig. 1 and Fig. 2 illustrate the partial cutaway side figure of one embodiment of the invention, and wherein Fig. 1 represents system under the reversing situation, and Fig. 2 represents that system is under high-speed case.
Fig. 3 represents system's birds-eye view.
The embodiment general introduction
One paddle wheel 1 is loaded into a basic fully enclosed pump chamber 11 and as an impeller.
A water inlet 8 is equipped with in these pump chamber 11 fronts, and a water outlet 4 is equipped with in the back.This pump chamber 11 forms in such a way, promptly the bottom between water inlet 8 and the water outlet 42 and paddle wheel 1 remain close to and force the water change of direction and along the bottom 2 of pump chamber 11 until being discharged from by water outlet 4.
The bottom 2 of pump chamber 11 keeps closely close with paddle wheel 1 in this zone, this just can prevent sealing from blade 7 effusions, and causes the pressure of water and speed to increase according to centrifugal principle.
The top 3 of pump chamber 11 is airtight pump chamber 11 because of its function, so can be designed to paddle wheel 1 a suitable distance is arranged.Because this pump chamber can be described as complete fully enclosed except that water inlet 8 and water outlet 4, so when water is discharged by water outlet 4, in this pump chamber 11, produce a vacuum.According to principle,displacement, this vacuum sucks pump chamber 11 by water inlet 8 with new water then.
For the vacuum in the pump chamber 11 is controlled, preferably by paddle shaft 9 being made hollow and disposing an air intake by chamber of each between 7 from the quill shaft to the blade, hole 10.Can make air pass through a control cock then and link to each other, use level of vacuum is controlled with system.
When ship berths or during with driven at low speed, must gas clean-up with water suction pump chamber 11 that will be enough.When the ship at high speed drives, i.e. the motion of passing water by ship is forced into water in the pump chamber, and the degree of vacuum in this pump chamber then can reduce.
For the various combinations of ship's speed and engine revolution, the level of vacuum an of the best is arranged all.
This can adopt ship's speed and engine revolution to be controlled as input by a computing machine.
Quite similar by the effect that reaches like this with the effect that reaches by a controllable pitch propeller.
Adopt a paddle wheel that rotates with current to replace rotation direction to become the general impeller of 90 degree that we can be avoided by the problem that rotation produced that becomes 90 degree with current with current.
Waterjet propulsor of the present invention does not produce the lower apron of friction.Only loss due to friction is from the bottom and the water outlet of pump chamber.
Calculate and test shown waterjet propulsor of the present invention can do forr a short time than present waterjet propulsor, lighter.In addition, the construction of this system and maintenance are all very simple.
For fear of the cavity problem, general waterjet propulsor must reduce the water velocity that enters this waterjet propulsor when high ship's speed.This is to resemble the water inlet that forms the diffuser by one to realize, and causes a very big water inlet.Waterjet propulsor of the present invention can the speed identical with ship's speed suck waterjet propulsor with water, and this just makes us can adopt the water inlet more much smaller than general waterjet propulsor.
Waterjet propulsor of the present invention can be with making with present waterjet propulsor identical materials.
For the ships of various driving engine and different size, the size of paddle wheel, shape and quantity can as in waterjet propulsor and the screw propeller the same manner regulate.
