Abstract

The utility model discloses a novel multi-engine ship and is characterized in that the ship is provided with more than four engines, has a two-gear gearbox (including an advance gear and a reverse gear) and straight plate propellers which are quite different from impellers and correspondingly mounted on two sides of the ship, and a common rear rudder is omitted. The novel multi-engine ship has a simple structure and a high ship velocity and is safer and more fuel-saving.

Description

Novel multiple steamer

(1) technical field: the utility model relates to the transport facility of rivers,lakes and seas, is a kind of novel multiple steamer specifically.

(2) background technology: as the shipping transportation means, common steamer is the single-shot configuration, and machinery space is installed in the steamer rear portion, and its moving system element is driving engine, power-transfer clutch, change speed gear box, transmission shaft and impeller.Marine engine is generally diesel motor or automotive gas turbine.Power-transfer clutch is generally platen power-transfer clutch or hydraulic clutch.Change speed gear box is drop-gear box, is generally more than the third gear two D Drives, a reverse gear.Impeller is the screw propeller that is shaped as fan-type.Such configuration makes steamer mostly be two sending out most and drives, and the arbitrary link et out of order of drive-system just needs the tugboat rescue, at the local et out of order away from land, can cause very large rescue cost.And common steamer need to be installed rear rudder, and the deflection by steering wheel reaches the purpose that turns to, and operating system is relatively heavier.The common steamer speed of a ship or plane is low, oil consumption.

(3) utility model content:

For the weak point of above-mentioned common steamer, the purpose of this utility model provides a kind of steamer that can realize the high speed navigation, and it can make turn radius less, more saves fuel oil.

The novel multiple steamer that can realize above-mentioned purpose equally comprises hull, driving engine, power-transfer clutch, change speed gear box, transmission shaft, screw propeller with common steamer.They all are to connect power-transfer clutch by driving engine to drive change speed gear box and rotate, and through the transmission shaft transmitting torque screw propeller are rotated again, drive steamer forward, travel backward.Difference is: described promotor site system occurs in pairs, and constituent elements is size equally, and correspondence is installed in the hull both sides respectively.Driving engine can adopt diesel motor or automotive gas turbine, contains low speed, at a high speed for making engine speed, and the utility model changes its Oil Switch into Thread valve and controls, and is beneficial to Long-distance Control.Power-transfer clutch adopts clutch with meshing magnetic faces, and more former platen power-transfer clutch or hydraulic clutch have lighter, safer, more durable advantage.The change speed gear box that the novel multiple steamer of the utility model adopts is flat fast case, and namely change speed gear box is exported engine torque with rotating speed.Therefore change speed gear box only has D Drive and reverse gear, thereby the gear-change operation system can be designed to operate before and after the electromagnetic valve, reaches the purpose of remote control.Cancelled again the low gear of common change speed gear box because of it, when travelling entirely at high speed gear, should be able to be more fuel-efficient.For engine power is better exported, transmission shaft should be short as far as possible, so driving engine generally adopts the vertical column type that becomes an angle of 90 degrees with hull, and this is applicable to mammoth tanker or warship; On small-sized steamer, driving engine can adopt the cross-arranging type that becomes 180 degree angles with hull, and so transmission shaft is slightly long, means that horsepower output is smaller.The screw propeller of the novel multiple steamer of the utility model adopts straight plate screw propeller, and its blade rectangularity is evenly distributed on the transmission shaft, and becomes an angle of 90 degrees with the tangent line of transmission shaft.Because of its hand of rotation with advance, direction of retreat is always consistent, can utilize more efficiently motor torque, and be suitable for the installations of organizing the promotor site system more, reach the purpose of many engine drive steamers, the steamer population equilibrium is more easily adjusted, and ship's speed is faster, safer.In order to make the novel multiple steamer ship trajectory of the utility model more hidden, block length shape wales can be installed on screw propeller, block spray (screw propeller can also be positioned under the hull), wales and screw propeller should be below floating lines.Take six steamers as example, because its driving engine is arranged installation relatively with three groups, therefore, there is a driving engine to change rotating speed when travelling, just can handle the steamer rerouting, the rudder that turns to of common steamer heaviness can be cancelled.

The utility model has the advantages that at a high speed, safe, fuel-efficient, turn rapidly, available puffer promotes steamer.

Fig. 2 is the lateral plan of Fig. 1 embodiment.

Fig. 3 is the back view of Fig. 1 embodiment.

Figure number sign: 1, hull 2, straight plate screw propeller 3, transmission shaft 4, change speed gear box 5, power-transfer clutch 6, driving engine 7, wales

(5) specific embodiment:

Mode is the plan structure figure after the novel multiple steamer of the utility model is the level of state as shown in Figure 1, its main body is hull 1, six cover promotor site systems are installed on the hull 1, based on the gravity balance principle, placed at three positions before, during and after six cover promotor site systems were divided into, and corresponding both sides, each position are equipped with the promotor site system of formed objects.Each promotor site system is comprised of driving engine 6, power-transfer clutch 5, change speed gear box 4, transmission shaft 3, straight plate screw propeller 2 respectively.Driving engine 6, power-transfer clutch 5, change speed gear box 4 closely connection are placed in the hull bottom, and are mounted on hull 1 straight plate screw propeller 2 outward by the transmission shaft 3 that rubber seal, metal o-ring are housed, and consist of the fundamental of drive wheel foot.

Such as Fig. 2, shown in Figure 3, straight plate screw propeller 2 is covered by microscler wales 7, to block spray.

The throttle of the driving engine 6 of the novel multiple steamer of the utility model adopts Thread valve, to reach wider modification scope; Power-transfer clutch 5 adopts clutch with meshing magnetic faces, can control at a distance; Change speed gear box 4 only has D Drive and reverse gear, is beneficial to an electromagnetic valve distant place and controls and fuel-economizing; Every blade rectangularity of straight plate screw propeller 2 evenly distributes, and vertical with the tangent line of transmission shaft 3, so is beneficial in the steamer both sides and installs, and reaches many engine-driven effects.

For the novel multiple steamer more than six driving engines, part promotor site system can cancel change speed gear box (not reverse gear, in pairs cancellation), to shorten propeller shaft length, improves engine power output.

On the profile, the novel multiple forward quarter of taking turns is the same with common steamer, and the up and down width at middle part, rear portion is the same, is flat-bottomed boat, and the wheel waterline is shoaled, and reduces resistance to motion, means that also the chance of hitting a submerged reef is less slightly.
