To the 26S Proteasome Structure and Function of the main composition of apparatus of the present invention part in conjunction with the accompanying drawings illustrated embodiment be described as follows.

Bow suction inlet 1(is referring to Fig. 1): strengthen the hull width, make the proper spacing of being separated by between each suction inlet.In order to reduce the value of hull width/hull length, prevent the shortcoming that friction drag is excessive, several suction inlets are set, make the shape of shaping front end collapsible tube 2 not level and smooth, and the space that between each collapsible tube, forms, can be used as the position that hydraulic efficiency gear is set.Increase suction inlet quantity in addition and can make power decentralized, and adopt lightweight miniature high-speed combustion engine, and do not need speed reduction gearing, thrust is dispersed on each row, so that raise the efficiency.

Shaping front end collapsible tube 2(is not referring to Fig. 7): make the upper end (H, W, L) when shipful of suction inlet 1 often be immersed in the underwater, even under ship in ballast and underloading (L, W, L) state, also make it most of not in the underwater.By induction pipe will be thus the resistance of the water that causes of collapsible tube suck, its purpose is to eliminate this resistance.Flooding quantity also increases when ship's speed increases, and with induction pipe 7 water is drunk up, and its major part as superfluous water, is discharged to outboard rapidly from discharge orifice 9.The NO.85104618.5 patent that it is equivalent to authorize.

Air and wave exhaust tube 3(are referring to Fig. 7): ship is at full load, suction inlet 1 is not often in water, but when under zero load and light condition, navigating by water, suction inlet 1 top forms a part that contacts with air, and do not have the place of discharged air, constitute a reason that underspeeds, therefore, start the auto reeling type winch 19 on both sides, the cover plate 18 of exhaust tube 3 is opened.And when fully loaded high speed is navigated by water, cover plate 18 must be closed.The cover plate 18 that makes exhaust tube in the navigation process is switch freely, but is docked on the harbour in the loading process, reach fully loaded before, cautiously rotate the cover plate 18 of exhaust tube 3 imports and outlet.Even there be slight leaking also not have what relation around the cover plate 18, after ship begins navigation, can prevent by means of hydraulic pressure and to leak.

The high-speed screw slurry sucks booster water pump 4, and (referring to Figure 14): this water pump has following feature: as the specific speed N that asks water pump _SThe time, in formula

$N_s\mathrm{=\; N}{}_{\mathrm{<figure-callout\; id="3"\; label="x\; Q\; H"\; filenames="931201349\_DRIMG8.png"\; state="\{\{state\}\}">x</figure-callout>}}\frac{\sqrt{Q}}{H^{}}\frac{{}^{\mathrm{3/4}}}{}$

In

N represents the rotating speed (r.p.m) of water pump

H represents the total (pumping) head of water pump

Q represents the discharge capacity (m of water pump ³/ min)

When the H=negative value, Q depends on the diameter of induction pipe 7, and the rotating speed of the rotating speed=diesel engine of N=water pump there is no need to regulate rotating speed for pumping up water, therefore, also can with the direct connection of the diesel engine of high speed revolution own, do not need pilot blade yet.

With the front end of induction pipe 7, be located at the not position that begins to restrain of shaping front end collapsible tube 2, be used for absorbing the water inlet resistance that causes because of convergence, and unnecessary water is ejected from discharge orifice 9 immediately.The scheme that proposes in No. 170 patent of invention is to adopt the high speed large-scale diesel engine, but the present invention is improved to the quantity (its unique reason is the ultra-large type diesel engine to be set have any problem) that increases suction inlet 1, thereby disperse lightweight small diesel engine is set, and can utilize the ready-made diesel engine product (referring to Figure 10,13) of production in enormous quantities.The suction power of each induction pipe 7, come the diesel engine 33 that is arranged side by side in the self-closed type pump house 12-1 mechanical cabin 13 upstairs, and utilize the big characteristics of water viscosity, make its ground high speed revolution that need not to slow down, its power acts on each pump common axis by the longitudinal axis, in addition diesel engine (referring to Figure 10) can be set simultaneously between each pump.

The combustion engine that these engine installations are equivalent to adopt on the boats and ships in the past rotates the sort of device of a bent axle, though on every pump a general commercially available put-put is set, its power is concentrated into mass action on the common axis of water pump 4.Obtain the pressure (hydraulic) water of energy by means of the rotation of propeller, flow through after the water pump of induction pipe 7, turn 45 °, and will restrain the energy that loses owing to pipeline, small axial flow pump 22 by high-power carries out supercharging again, from the mode of spout 8, form the mean level water column and in the exterior water of hull, spray then with nozzle ejection.The water that ejects, the vortex drag stream that produces with the stern-side of pump house 12-1 impacts, and also contacts on coned face with hull bottom water outward simultaneously and produces friction drag, and the recoil of these resistances just produces thrust (referring to Fig. 5,6).

Biologies such as fish are arranged in the ocean, and foreign matters such as the dirt that swims in addition in order to protect the water pump pump impeller, are provided with anti-dirt device at the front end of induction pipe 7.

Middle part water pump 5 and stern pump 6(are referring to Fig. 5): the electric power that this water pump is sent by gas turbine power generation cabin 15 and steam turbine power generation cabin 16 drives.They are separately positioned in closed pump house 12-2, the 12-3.Water ejects after pressurizeing by axial-flow pump (referring to Figure 15).The vortex drag stream that the stern-side of water and each pump house produces impacts, and also contacts and produce friction drag with hull bottom water outward on coned face simultaneously, and the recoil of these resistances produces thrust.This just is equivalent to that boats and ships in the past are installed in the exterior propeller propelling unit of hull and disperses, and each propeller blade is located at pipe interior.

Boats and ships retreat with jet pipe 10(referring to Fig. 6,11).This boats and ships pull in to shore and anxious situation such as bring under need to have the ability that retreats.Be located at the water pump 4 at the two ends, the left and right sides of middle part pump house 12-2 and stern pump house 12-3, pattern as shown in figure 14.Power is provided by electrical motor 43-2, water generates is regurgitated penetrate.

Conducting element 11(is referring to Fig. 4-6): owing to water with excess pressure from spout 8 ejections, when directly impacting the bow sidewall paneling of closed pump house 12-2,12-3, the resistance of water was bigger during boats and ships advanced, therefore wallboard is made the hollow excrescence that front end is a taper, eliminate wave making resistance, with penstock water conservancy diversion and compiling in addition, and move the water to flow into the suction inlet of induction pipe 7.

Closed pump house 12-1,12-2,12-3: owing to pipeline is set water is introduced, so allow anything but to leak in boats and ships inside.Therefore to make cabin have leak tightness completely, and not influence boats and ships itself water. Booster water pump 4,5,6, induction pipe 7, jet pipe 8, the electrical motor 43 all equipment of sucking are set in cabin.The boats and ships that hull is long are also set up the middle part pump house at the middle part.This is because hull is long more, thus the cause of the big more reduction of friction drag propulsive force.

Closed bow power machine cabin 13: be equivalent to the engine room of boats and ships in the past, in this cabin, with hydraulic efficiency gear and power plant be arranged on each pump directly over, as shown in figure 13.

Concentrate driving compartment 14: equipping control computer, various sensor and high-tech product, various functions are being concentrated in this cabin, guaranteeing the reliable and secure driving of boats and ships by remote handing.

16: two cabins in gas turbine power generation cabin 15 and steam turbine power generation cabin constitute an integral body, adopt new-type pressure boiler cycle mode.Be provided with air compressor, H Exch, automotive gas turbine, electrical generator in 15, utilize connecting pipeline and transmit mutually between the equipment downstairs.Be provided with boiler (being positioned at the middle part), feed water heater, feed pump, condenser, steam turbine and electrical generator in 16.

This cycle mode is, boiler in the steam unit complete equipment and the combustion chamber in the automotive gas turbine is shared, and the high pressure air that comes out from air compressor is transported in the boiler, makes its pressure combustion, utilizes the waste gas of combustion chamber to drive automotive gas turbine.

The electric power of sending from these two generating cabins can satisfy whole electric power required in the boats and ships.

Partial wave plate 17(is referring to Fig. 4-a): when billow surpasses forward, wave is rived to operator's compartment 14 both sides, make the visual field unaffected, so that guarantee driving work.

The import and export cover plate 18(of air and wave exhaust tube 3 is referring to Fig. 7): in order to keep the high speed navigation of boats and ships, this cover plate can correspondingly carry out switch according to the drinking water depth.This cover plate is located at import and outlet, has two, and the small-sized auto reeling type winch 19 of Kao Yitai is handled its switch.The service condition that now will manage 3 outlet cover plates 18 is described as follows.As shown in figure 16, position (1) is to lean on the cable wire of a winch 19 outlet cover plate 18 closing state; Loosen cable wire, open the position of cover plate to (2) by the deadweight of cover plate; Make cover plate reach the position of (3) by discharged air and water; When navigating by water at a high speed, cover plate is subjected to the pressure of outside of ship's bottom flowing water and reaches the position of (4); When pulling winch 19 cable wires, cover plate 18 is closed again.

Hydrofoil plate 20(is referring to Fig. 4,5,6,7): because the weight of this ship concentrates on the position of each pump house, therefore, below 12-1,12-2,12-3, lean on bow one side, with cup spring installation shaft 24 and anchor shaft 25, be installed in below baffle plate folding and unfolding cabin 23 and pump house 12-2, the 12-3 hydrofoil plate and bilge top.

Under the effect of the comprehensive effect of jet stream thrust, when the speed of ship is increased, produce resistance on the hydrofoil 20, cup spring 24 shortens, and when being reduced to short status, the hydrofoil plate upwards rotates about 5 °, and boats and ships are risen, and reduces the area of wetted surface of hull.This ship buoyance lift that makes is the purpose that the hydrofoil plate is installed; Another purpose is, makes the big bow of weight often keep up posture, under any circumstance, and the danger that all will avoid bow to bore in the water; That is to say that this is in order to obtain high-speed and stability of hull simultaneously.In addition, the hydrofoil plate around the purpose of bilge setting also is, in order to relax the impact of shear wave by stretching of cup spring 26, and makes the effect that is subjected to shear wave and careen is set back.

Bow portion produces the high speed axial flow pump 22 of jet stream, and (referring to Figure 14): this water pump can adopt general-duty high capacity, low-lift pump.In addition, on middle part water pump 5, stern water pump 6, also can be provided with, and with electrical motor 43-1 as its power.

Closed baffle folding and unfolding hydraulic-driven cabin 23: be located at pump house 12-1 below, except the part of discharge orifice 9, water is kept leak tightness completely, baffle plate 31,32 folding and unfoldings are in wherein, and the assurance baffle plate is mobile, with around the discharge orifice 9 around the material of last flooding safety, even when baffle plate 31,32 moves, also do not soak.This cabin is designed to an independently cabin, just in case soak also unlikely pump house 12-1 and the hull of influencing.

Oil pipe is held concurrently conduit (close discharge orifice with) 27 and oil pipe (recover baffle plate 31,32 positions with) 28(referring to Fig. 7,8,9): shaping front end collapsible tube 2 is not along transversely arranged, dwindle along with pipeline and form the space, above-mentioned two groups of pipes are passed through from bow side and stern-side, hydraulic oil in the pipe is by Hydraulic Pump 36 pressurizations in power machine cabin 13, and flow into baffle plate folding and unfolding cabin 23, drive baffle plate 31,32 and move.

Connecting rod (stern-side) 30(of the connecting rod (bow side) 29 of band piston and band piston is referring to Fig. 9): be located at that conduit (diameter of the oil pipe 27 that its diameter is interior with introducing folding and unfolding cabin 23 is identical) is interior, an end is installed on the piston and the other end is installed in the two groups of connecting rods 29,30 on the baffle plate 31,32, the fluid pressure that is passed to each oil pipe promotes, baffle plate 31,32 is moved, after current are blocked, oil pressure in the oil pipe 28 raises, and makes baffle plate return to the home position (referring to Fig. 9 a).

Baffle plate (bow side) 31 and baffle plate (stern-side) 32, (referring to Fig. 9): this baffle plate adopts the iron plate that imposes antirust agent on lightweight aluminium alloy plate or the surface, is the whole sheet material that a sheet of planar concave-convex surface, length are substantially equal to the hull width.It is far away more that bow suction inlet 1 is left in the position of discharge orifice 9, and it is good more that the shape of collapsible tube 2 becomes, and resistance also reduces (referring to Fig. 7), and therefore, the miles of relative movement of baffle plate 31 is longer than the miles of relative movement of baffle plate 32.So 31 and 32 positions that close up often are positioned at the stern-side of discharge orifice 9.

The flooding safety material 42 of discharge orifice 9 is referring to Fig. 8.In the space in baffle plate folding and unfolding cabin 23, discharge orifice 9 around, be embedded with flooding safety material 42.As shown in the figure, respectively the marginal portion of baffle plate 31,32 is clamped with this material, under clamp position, even by hydraulic pressure moving stop 31,32, water can not immerse in the cabin yet.The material and the technology of this material are as follows: with materials such as petrochemical industry goods such as whippy polyurethane or rubber system sponges, with carbon fiber or glass fibre its pressure seal is coated, to impose synthetic resin be coating to the part that contacts with baffle plate 31,32 then, its effect just like people's lip close the same can water repellant immersion.

Now the progradation with this boats and ships is described as follows:

All propulsion machinerieies all often are immersed under the water surface, present water filled state.Each water pump starts simultaneously, water in the feed pump is exerted pressure, begin to suck new water in each induction pipe 7, and penstock sprayed simultaneously from each spout 8, ship leans on the recoil of the injection that forms on the horizontal water column coned face to begin to advance, ship when initial motion, because of and water between friction drag big, so with lowsteaming; Along with advancing of ship, water flows into front end collapsible tube 2 from suction inlet 1, inhales the part of going except being inhaled into pipe 7, and remaining water is discharged from discharge orifice 9 immediately, and in becoming the process of moderate velocity, friction drag diminishes.

At this moment, an important item is that even ship's speed increases, the flow that flows into the water of suction inlet 1 also increases, and increased slightly by potential difference head produce power, but this energy becomes current, discharges from discharge orifice 9.Obtain the water of energy by pump power, from nozzle exit 8 ejection outboards, impact mutually with the vortex drag stream that each pump house 12-1,12-2,12-3 stern-side take place, also on coned face, contact simultaneously and cause friction drag with the water of outboard, the recoil of these resistances produces thrust, with propulsion of ship.Itself and rotation propeller propelling unit, the ship in the past that water is rearward pushed away is identical.Flow deformation also appears in water easily under the effect of small power, thereby leaves flight path at the boats and ships rear, can not disappear in a period of time.The water that ejects can not disappear immediately, and its energy is also residual and swim a period of time in water.The present invention utilizes this characteristic, propulsive force is distributed to the very big hull bottom of area, utilize lightweight miniature high-speed diesel engine and need not deceleration, backward between the pump house 12-212-3 of Pen Chu penstock and progressive boats and ships, the high more time that both meet of ship's speed is short more, so the generation comprehensive effect behind the water that the suction residual amount of energy is bigger in the induction pipe 7, further makes speed increase.Therefore, if the big boats and ships of hull length, just plural pump house is set up in the position in the middle.

Situation about fast stopping ship further specifies as follows.

In driving compartment 14, urgent when the knob (referring to Figure 13) when pushing, each pump 4,5,6 stop motions, electrical motor 43-2 and hydraulic pressure are started working with electrical motor 34.Oil in the Hydraulic Pump 36 work back pumps hydraulic fuel tanks 35.Regulate oil pressure with pressure-modulation valve 37 earlier, use flow regulating valve regulation flow again, the pressure with hydraulic oil is delivered to bow side and stern-side respectively then.Because the miles of relative movement of the baffle plate 31 of bow side is long, so direction of passage control cock 39 passes to oil pipe 27 earlier strongly with the pressure of hydraulic oil; The situation of stern-side is, regulates again with 38 pairs of flows of flow control valve, makes its flow be fit to the short needs of baffle plate 32 miles of relative movement, again direction of passage control cock 39 with the transmission of pressure of hydraulic oil to oil pipe 27.This hydraulic pressure transfer is in the conduit 27 in baffle plate folding and unfolding cabin 23, and pushing piston, and this masterpiece is used for connecting rod 29,30, and the baffle plate 31,32 that is installed on the connecting rod just produces mobile.Yet, job procedure below just is described, high pressure oil is not to transmit pressure gradually, in fact, because not with the hydraulic oil of energy often oil pump and oil pipe abrim, according to pascal's principle, by the hydraulic fluid pressure that Hydraulic Pump 34 applies, act on immediately on the piston 29,30, just begin immediately to move at pressing button back shield 31,32, and seem like the folder current of both sides, to close up, discharge orifice 9 is closed (referring to Fig. 9-b), meanwhile, electrical motor 43-2 sends maximum power, spray water with maximum capacity from retreating, make ship approach the state of bringing to jet pipe 10.Then, electrical motor 34 is automatically shut down, and Hydraulic Pump 36 also quits work.So near not shaping front end collapsible tube 2 and suction inlet 1, current generation counter-flow makes ship bring to fully immediately (process that similar road transport stops by friction drag) by its resistance with regurgitating to penetrate on the road surface.

In the front of boats and ships, produce vertical water column buffering ripple this moment, boats and ships are taken advantage of this ripple and are risen, so although there not be to bump against suddenly at full speed impact such on the cliff of bank, but still the interior safety method of ship resemble the rapid need be arranged.

If confirm that boats and ships halt; and accident prevention is after possible trouble; start electrical motor 34 and Hydraulic Pump 36 once more; the directional control valve 39 of bow side makes two-way cut out the hydraulic limitations valve work of (any pipeline is all obstructed); hydraulic pressure only passes to the oil pipe 27 of stern-side; at baffle plate 31; 32 maintenances are closed up under the state mobile a little to the bow side; state shown in Fig. 9-c (refer to can to the state of the oil pipe fuel feeding on both sides); the directional control valve 39 on both sides is transformed into oil pipe 28 sides; hydraulic pressure transfer arrives oil pipe 28, and acts on piston 29; on 30, with baffle plate 31; 32 pushed home are (referring to Fig. 9-a); electrical motor 34 is automatically shut down, and Hydraulic Pump 36 also quits work.

As mentioned above, this ship is provided with the urgency of the using when dangerous equipment that brings to that meets with, can guarantee high speed, stable continuous navigation, even if in long-term navigation, electrical generator possibility et out of order, but many diesel engines can not be simultaneously et out of orders all, and can be in process only by diesel engine navigation (function of ship in the past), the fault of repairing electric system.

When turning to flexibly; with the pump 5,6 that is provided with among pump house 12-2, the 12-3 by about be divided into 2 groups every group each 3 (referring to Fig. 6,11); make the pump of a group strengthen simultaneously or weaken workload just can turning to; especially when the needs sharply turning; can make one group of dead halt in two groups of pumps; another organizes then full-load operation, so just can avoid the generation of most of ship collision accident.

The fast stopping ship boat equipment and the spraying propelling apparatus under bottom of ship that utilize the present invention to propose can obtain following all effects.

(1) present, ship can't be realized anxious bringing to, but after utilizing this device, boats and ships also can be realized anxious bringing to as road transport. Simultaneously, can also turn to neatly, can avoid the generation of most of accident so need not bring to by just turning to.

When (2) ship's speed is high, can sucks a large amount of water of possessing residual amount of energy, thereby can produce comprehensive effect, realize at a high speed navigation. In addition, removed the rudder and the propeller that hinder at a high speed navigation, contacted with the water of outside on the water column coned face of level and obtain recoil strength.

(3) wave of ocean itself is unfavorable for ship's navigation, and the present invention very effectively utilizes wave, and it is good that the navigation of boats and ships has been play a part. That is, the top of boats and ships wave in front is sucked or passes, like this, compare with boats and ships with existing, fore upwards floats little, thereby can not pierce trough, in addition, owing to be the big ship of hull width, so be subjected to the impact of shear wave littler. In a word, compare with boats and ships with existing, front and back pitching and lateral oscillation are all little, so riding comfort is good.

(4) also less than now using ship, bent axle vibrates without spin, so travelling comfort is good for the vibration of diesel engine and noise.

(5) general, high speed vessel or huge ship at high speed by the time, produces bigger navigation ripple, this makes troubles for other canoe, when adopting the boats and ships of this device to pass through, can not influence other ship.

Claims (1)

1, a kind of marine propulsion and hull shape thereof of utilizing the residual amount of energy of water, the penstock that was once spraying, take advantage of residual amount of energy in addition during, to spray after its suction again by mid-ship, and this process on the quarter repeated once, on the contact surface between the water of coned face that injection water forms and outside of ship's bottom, by friction drag with induce that to flow the caused recoil of vortex drag be exactly the thrust of boats and ships.
