Abstract
The utility model relates to a ship propelling system, in particular to an ultra-shallow-draft ship propelling system. The ultra-shallow-draft ship propelling system comprises a diesel engine installed in a ship's cabin and obtained by dismounting an internal machine of a side internal-external machine, a speed changing box, a shafting, a propeller system and a tunnel type ship stern, wherein the speed changing box, the shafting and the propeller system are driven by a straight shaft. The side internal-external machine is connected with the speed changing box through the diesel engine and a transition plate, the speed changing box is connected with the propeller system through a propelling shaft, and the propelling system is installed under the tunnel type ship stern. The diesel engine adopted by the ultra-shallow-draft ship propelling system is light in weight, the ship displacement is decreased, the propeller diameter can be decreased by adopting the serial propeller design, and propellers do not exceed a hull base line and accordingly the draft is decreased by adopting the hull tunnel line shape. An ultra-shallow-draft powerboat with only 0.33m draft can be designed, and indexes of existing shallow-draft ships with 0.45m draft are exceeded greatly.
Description
Technical field
The utility model relates to a kind of marine propuision system, is specially ultra-shallow draft boats and ships propulsion system.
Background technology
Spitkit adopts the inside and outside machine propulsion mode of the side of a ship or d-axis propulsion mode conventionally, wherein, the diesel engine of the inside and outside machine propulsion mode of the side of a ship is the LD-diesel of high rotating speed (4000rpm), its diesel engine is installed in cabin, on middle-grade stern transom plate overboard, be connected thrust is provided with hull, the tail machine that comprises drop-gear box and screw propeller and middle-grade at right angle setting are in outboard, and this propulsion mode drauht is large, in some super shallow rivers, cannot apply; And d-axis propulsion mode, diesel engine is the diesel engine of higher rotation speed (<2300rpm), its diesel engine and gear case are installed on cabin, shaft extension goes out outboard and drives single screw propeller, screw propeller position is stream line pattern, weight, the size of d-axis propulsion mode diesel engine are large, and diameter of propeller is large, often can not meet screw propeller not only in underwater but also the requirement that does not exceed hull baseline; Above two kinds of conventional propulsion modes are all very limited as the propulsion system of ultra-shallow draft boats and ships.
Utility model content
According to above-mentioned technical matters the utility model, provide a kind of propulsion system that ultra-shallow draft boats and ships use that goes for, concrete technical scheme is:
Ultra-shallow draft boats and ships propulsion system, comprise the inside and outside machine diesel engine of the installation side of a ship belowdecks, it also comprises change speed gear box, cardan shaft and propeller system, and tunnel type ship stern, the inside and outside machine of the described side of a ship passed through scale with diesel engine and was connected with change speed gear box, change speed gear box is connected with propeller system by cardan shaft, and described propeller system is arranged on type ship stern below, tunnel.
Described propeller system comprises two screw propellers, and two screw propellers are connected on cardan shaft.
The ultra-shallow draft boats and ships propulsion system that the utility model provides advances both advantages in conjunction with machine inside and outside the side of a ship and d-axis, avoid both shortcomings, the middle-grade of machine inside and outside the side of a ship and tail machine are dismantled, change the diesel engine of machine inside and outside the side of a ship into d-axis propulsion mode, by transition disc, connect diesel engine case and gear case case, by the change speed gear box of ship design requirement coupling appropriate speed ratio, and changing the axle frenulum single-blade of conventional d-axis propulsion mode into tandem oar, linear employing tunnel, hull tail undercarriage place line style is to guarantee the incoming flow of screw propeller place water.
The diesel engine that the utility model adopts is lightweight, reduces vessel displacement, and the design of tandem oar can reduce diameter of propeller, coordinates hull tunnel linear, and avoiding screw propeller to exceed hull baseline increases draft; Can design and absorb water the only super low draught motor boat of 0.33m, the index of 0.45m shallow draught vessel before superorder far away.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The accompanying drawings specific embodiment of the present utility model, as shown in Figure 1, ultra-shallow draft boats and ships propulsion system, the inside and outside diesel engine 7 for machine of the side of a ship is installed belowdecks, change speed gear box 5, cardan shaft 4 is through hull afterbody and the outer propeller system 2 of installing of cabin, the inside and outside machine of the side of a ship passed through scale 6 with diesel engine 7 and was connected with change speed gear box 5, change speed gear box 5 is connected with propeller system 2 by cardan shaft 4, propeller system 2 is arranged on the below of tunnel type ship stern 1, bracing strut 3 is supported on propeller system 2 outside ship storehouse, the stability that keeps propeller system 2, propeller system 2 comprises screw propeller 21 and screw propeller 22, screw propeller 21 and screw propeller 22 are connected on cardan shaft 4.
Claims (2)
1. ultra-shallow draft boats and ships propulsion system, comprise the inside and outside machine diesel engine of the installation side of a ship belowdecks, it is characterized in that: also comprise change speed gear box, cardan shaft and propeller system, and tunnel type ship stern, the inside and outside machine diesel engine of the described side of a ship, by crossing scale, be connected with change speed gear box, change speed gear box is connected with propeller system by cardan shaft, and described propeller system is arranged on type ship stern below, tunnel.
2. ultra-shallow draft boats and ships propulsion system according to claim 1, is characterized in that: described propeller system comprises two screw propellers, and two screw propellers are installed in series on cardan shaft.
