Description
A kind of power propulsion system of shipping high speed navigation, it relates to a kind of new propulsion of ship technology, is the application of spraying technique on naval vessel, submarine.
Up to now, most power vessels all are that screw propeller is installed in behind the ship under water, promote the steamer that boats and ships advance by the diesel engine driven rotary, and remaining is a wooden boat.
The purpose of native system is that will to solve one (be ship kind, load capacity, power size under original condition ... Deng), by changing propulsion mode, its speed of a ship or plane is improved several times (or more), thereby reach the route speed that improves boats and ships, shorten voyage time, the purpose of energy savings.
Design philosophy is, removes existing steamer produces resistance when navigating by water at a high speed mainly parts under water, i.e. screw propeller and mechanical rudder, with nozzle spray water backward and ship in direction controller replace.Give water entirely with the load-bearing of hull and load, with the dynamic concentrated as much as possible aspect of advancing of pushing boat used of the institute of ship, so that it produces big as far as possible acceleration/accel.
The ship lower apron is made drops or eggshell state, remove screw propeller and mechanical rudder, reduce resistance as far as possible; Neck at ship is provided with the inlet opening under water, and both sides behind ship (1/2nd back intervals before 3/4ths of about hull length) symmetry is installed two pairs to four pairs nozzles.Push boat preceding and then replace the effect of screw propeller with spray water the backward thrust that produces of nozzle, with what, the different effect that replaces rudders of control both sides injection flow rate.Diesel engine drives the water of water pump before with ship and is drawn in the ship from the inlet opening in the ship, and its result can produce a power of drawing ship to advance when ship is static, can reduce the suffered resistance of ship (also quite having increased a pulling force) when height speed is advanced; The water pressurization that is drawn in the ship sprays at a high speed from both sides, ship rear portion, consequently produces the thrust of pushing boat and advancing.Pulling force and thrust to the result of ship effect be make ship be subjected to size certain push ahead make a concerted effort.This makes a concerted effort to make boats and ships to do acceleration movement.
According to newton's second law of motion, object is made a concerted effort under the effect of F outside, the acceleration/accel a that object obtains with outward with joint efforts F be directly proportional.Be inversely proportional to the quality m of object, sense of motion is consistent with the direction of making a concerted effort outward.
That is: a=F/m (or F=ma)
And speed V=V
0+ at
From static to motion, V then
0=0
V=at, speed was directly proportional with the time.
Here, the quality m of ship is constant, in a cooresponding scope, and resistance F
ResistanceAlso may be constant, F makes a concerted effort
CloseWhat and the pressure one of pump-out and injection flow rate regularly be one quantitative, so
F
Close-F
Resistance=ma
Produce accelerated movement.
The route speed V=at of boats and ships, promptly V is directly proportional with time t.Along with the increase of time t, the V increase that will be directly proportional reaches at a high speed, purpose of energy saving.
Mainly by inlet opening (1), coolant inlet pipe (2), the place ahead is to controller (3), diesel pump group (4), unidirectional non-return valve (5), water tank (6), back water spray control cock (7), tank line (8), rear be to controller (9), rear nozzle (10), pressure regulating valve (11), high pressure air bag (12), preceding water spray control cock (13) and front nozzle (14) also have Air compressor and corresponding instrument, instrument to form.As shown in the figure.

2. coolant inlet pipe (2): refer to the pipeline between control from loudspeaker to the place ahead, about this pipe is divided into from the centre two (also can every limit be further divided into two-layer up and down, adapt) with the structure of loudspeaker.
3. the place ahead is to controller (3): two inlets (or four inlets) are arranged before this controller, after an outlet is arranged, the inside has one can close the left and right sides control desk (all opening simultaneously at ordinary times) that the right side (or a left side is opened on the right side, pass) is opened on a left side, can also be installed in series one and shut out down or the control desk of opening under closing up and down, to be applicable to Submarine.
4. diesel pump group (4): this is the power that boats and ships advance.The gross horsepower of diesel engine equates with the power of corresponding boats and ships, and gross horsepower is divided into three groups by two, three, five, or is divided into three to five parts.Select the diesel engine of close power then, be equipped with the water pump that adapts again and form the diesel pump group.Requirement to water pump is that discharge capacity is big as much as possible under the situation of diesel oil function burden, and pump pressure is high as much as possible, the hydraulic pressure that is drawn into can be gone into have high-voltage water tank (pressure is about 3～10 barometric pressures in the water pot).
5. unidirectional non-return valve (5): be contained between the coolant outlet pipe and water tank of water pump, when water pump is gone into water tank with hydraulic pressure, opening of valves, water enters water pot.Otherwise valve cuts out.
6. water tank (6): it is to utilize bottom, ship storehouse some are difficult for spaces of utilizing and part ship storehouse (also can increase the volume of ship and do not increase the load capacity of ship) for this reason and make withstand voltage, resistant to corrosion water pot, and shape will be decided according to particular case.Volume will make the upper limit spray more than one minute to the enough all nozzle standard-sized sheets of the water yield between the lower limit.Preceding order is arrived pumping line to non-return valve; The least significant end water receiving pipe is to the control cock of spraying water behind the ship; Most significant end at water pot connects automatic pressure regulator.The dress compression indicator is gone back the filled with water level controller, safety valve, equipment such as blow off valve to monitor the operation pressure of water pot on the water pot.
7. water spray control cock (7): one at the every pair of nozzle, the control nozzle is devoted oneself to work what.Before water receiving jar coolant outlet pipe, after connect the rear to controller, available electromagnetic valve.
8. tank line (8): refer to from the water spray control cock to the rear pipeline section between controller.One at the every pair of nozzle is separated from each other.
9. the rear is to controller (9): one at the every pair of nozzle, and whole same axle controls, structure is identical to controller with the place ahead.The last hole of each controller, two holes, back, centre have one can close the control desk that the right side (or a left side is opened on the right side, pass) opened on a left side, and the both sides balance is all opened at ordinary times.
10. nozzle (10): at the interval before to 3/4ths after the hull 1/2nd, two pairs to four pairs nozzles of both sides symmetry installation.The angle of nozzle water spray and ship axis is between 30 ° to 45 °.The size of nozzle diameter depends on the advance size of required thrust of ship, can be identical diameter, also can be different diameters.But load onto the lid of SELF CL outside nozzle, when not spraying water, SELF CL is in case marine life adhere to and block.
11. automatic pressure regulator (11): its effect is to guarantee in the water pot constant compression force is arranged, and makes the glassware for drinking water of ejection that certain kinetic energy be arranged.Its front end connects the high pressure air bag by air diverter valve, after connect the most significant end of water tank.Its principle of work is when the pressure of back water tank is equal to or greater than required pressure, the SELF CL air inlet valve; When the pressure in the water pot of back during less than required pressure, open valve automatically, allow pressurized air enter water pot, utilize the scalability of air to go to compensate and regulate in the water pot because of the water pressure that overbalance produces of coming in and going out changes, guarantee that pressure is 3～10kg/cm
2In certain certain value.Even require all whole unlatchings of nozzle can guarantee that also the pressure that compensates in the water pot is constant.
12. high pressure air bag (12): the air that compresses is pressed in it about 50kg/cm of pressure in tank dome by air compressor
2, to guarantee the charging pressure required air quantity of supply water tank.
The control cock (13) 13. spray water forward: its structure is identical with back water spray control cock, and its effect is need slow down, brake, open this valve when falling back when ship, allows water pot water spray forward.
14. Pen Shui nozzle (14) forward: be installed in the both sides, forward quarter, have only a pair ofly, its structure is identical with backward nozzle.
Also have Air compressor, safety valve, aie escape valve, compression indicator etc.Other supervision control instrument equipment is identical with former ship.
Working process: before ship starts, open the air diverter valve of high pressure air bag.Regulating automatic pressure regulator makes the compression indicator on the water pot be designated as required force value.When sailing, open the water spray control cock, the high pressure water in the water pot just promotes ship advance (or direction of passage controller control turning) through the direction controller from the nozzle ejection.Meanwhile, start corresponding diesel engine, running steadily back drive water pump is drawn water, and the hydraulic pressure of suction is gone in the water pot to replenish water pot.The ejection that high pressure water in the water pot does not stop promotes ship advances, and the water with before the ship that water pump does not stop again is drawn into and replenishes the water that reduces because of discharge in the water pot.That does not so stop goes on, and ship has just advanced under the draw water pulling force that produces and the thrust combined action that produces of spraying water.The action direction that cause is made a concerted effort aboard ship is consistent with the ship working direction, and is constant force, so make ship give birth to a uniform acceleration motion.The growth that the route speed of boats and ships is directly proportional along with the increase of time, when the route speed of boats and ships reaches our required speed, closed portion nozzle (or changing out small nozzle) then, the thrust that remaining nozzle water spray is produced is enough to overcome the suffered resistance of boats and ships, keeps acquired kinematic velocity.
We can be by regulating the pressure and the requirement of how much satisfying the required acceleration size that sprays water in the water pot.In the work,, when reaching the lower position, start high-power diesel unit work (or increase unit) automatically if the water level in the water pot descends always; If water level rises always, when reaching upper limit water level, just change out miniwatt unit (or stopping certain unit) work automatically.
Slow down, brake or retreat as need, can be interrupted or the continuous unlatching control cock of spraying water forward, the high pressure water in the water pot is sprayed the effect that to play deceleration, brake or fall back forward.
When the need ship is turned, rotate steering wheel, before making (back) direction controller control both sides advance (going out) water yield difference, make the power of both sides generation different, reach the purpose of turning.For example, ship will turn left, and rotates steering wheel, makes ship the place ahead control the flooding quantity of the flooding quantity of inlet opening, the left side more than inlet opening, the right to controller, so produce a meiobar lower than the right at the ship neck, ship to the Zola, has been realized left-handed turning; Otherwise right-hand turning.Also make simultaneously the ship rear spray than the more water of right nozzle to controller control left nozzle, thereby the left side produces a thrust bigger than the right behind ship, and stern is pushed away to the right, the ship neck has been a left-handed turning; Otherwise right-hand turning.
Ship need stop to the harbour, as long as turned off all water spray by-pass valve controls.This moment, the diesel pump group was also worked, and gave the water pot amount of makeup water, prescribed a time limit when water level reaches, under the diesel pump group ability full cut-off.If ship does not stop, also need adjusting of a little, the water spray control cock that can open front or rear nozzle (also can be certain on one side front and back nozzle) this moment again once, allow in the water pot water more forward (or backwards, or on one side) towards certain sprayed some just.If ship has stopped to walk, shut air diverter valve, open the drain tap of water tank, bleed off the high pressure air in the water pot, make to be in atmospheric pressure state in the water pot.
Advantage: because removed exposed parts under water such as screw propeller and rudder, make ship under the effect of constant force, do acceleration movement, can under the situation that does not increase ship power, accomplish high-speed operation.Can be several times (also may be higher) of present ship.Can improve the flying power of ship greatly, energy savings.Owing to only need the just ejection on demand of opening controlling valve water, so ship starts soon, advance, retreat, about the turning collision avoidance all very flexible, can have very strong self-saving ability.Applied widely, can make all ships such as various high speed warships, high speed transport, salvor, lifeboat, Submarine.Make new ship and all be easier to the transformation obsolete vessel, armamentarium all can be based on our country.Navigation, communication, illumination, firepower and living facilities etc. need not redesign.And individual other parts are also very simple as the structure of automatic pressure regulator, direction controller, make easily.Whole ship with short production cycle, cost can be very not high.General shipbuilding yard all can be made.
