Abstract
The utility model provides a low-resistance ship body which comprises a ship body and propellers; the ship body adopts streamline structure; a left buoy and a right buoy are fixed under the ship body and parallel to the ship body; for each buoy, the propeller is mounted on the front part of the buoy; a faring is nested on the front part of the propeller, the fairing and the buoy are spliced to form a fusiform buoy; the interior of each buoy is divided into two parts, the front part separation bin is the power bin in which a reversing mechanism is mounted, the propeller is mounted on the output shaft of the reversing mechanism, the input shaft of the reversing mechanism is threaded through the suspension bracket of the buoy to be rotationally connected with an engine in the ship body; the rear part of the buoy is a buoyancy bin and the diameter of each propeller is 1.5-2 times of the diameter of the buoy. As small resistance is applied on the fusiform buoys in moving process, the propellers are combined with the fusiform buoys; thereby, the water inlet flow of the front parts of the propellers has small resistance, the rear water flow can reduce the eddy through the fairing effect of the buoys; the work efficiency of propellers is improved.
Description
Technical field
The utility model relates to boats and ships, particularly the design of hull construction.
Background technology
During ship's navigation, consumption of power mainly is to overcome the suffered resistance of hull, wherein most of resistance that hull is caused for water.Existing ship, hull are designed to stream line pattern as far as possible, but because screw propeller generally is contained in afterbody, and it is very near with the stern distance, the current that screw propeller the sucks hull of flowing through earlier, hull itself has just produced resistance to these current like this, and hull is brought into play the efficient of screw propeller and is impacted.In addition, because the current that screw propeller produces contain a large amount of eddy current compositions, also reduced the promotion efficient of screw propeller.
Summary of the invention
The utility model purpose is to provide a kind of can give full play to propeller efficiency, hull structure that resistance is low, to reach purpose of energy saving.
Scheme of the present utility model is: a kind of low resistance hull, comprise hull and screw propeller, hull adopts streamlined configuration, two floating drums parallel about the hull below is fixed with hull, on each floating drum, screw propeller is installed in the front portion of floating drum, the screw propeller front is with fairing, and fairing and floating drum are spliced into a spindle shape, and floating drum inside is divided into two parts, anterior compartment is a power bin, the inside is equiped with direction reverser, and screw propeller is contained on the output shaft of direction reverser, and the suspension bracket that the input shaft of direction reverser passes floating drum is connected rotation with the interior driving engine of hull, the rear portion of floating drum is a buoyant cabin, and diameter of propeller is 1.5-2 a times of spar diameter.
The utility model has the advantages that: resistance suffered during owing to the spindle object of which movement is minimum, and two floating drums under the hull can hold up hull again, have so just reduced the resistance when boats and ships are advanced; Screw propeller is combined in the N, and the anterior suction of screw propeller resistance to water-flow is little, and diameter of propeller is 1.5-2 a times of spar diameter, make the current at rear portion along the floating drum surface flow, through the valve action of floating drum, can reduce eddy current, improved the work efficiency of screw propeller.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is a construction profile scheme drawing of the present utility model.
Fig. 2 is the Facad structure scheme drawing.
Fig. 3 is the cutaway view of A-A direction among Fig. 1.
Mark among the figure: 1 hull, 2 floating drum suspension brackets, the input shaft of 3 direction reversers, 4 fairings, 5 screw propellers, the output shaft of 6 direction reversers, 7 direction reversers, 8 power bins, 9 floating drums, 10 floating drum supports.
The specific embodiment
In conjunction with illustrated in figures 1 and 2, the low resistance hull comprises hull 1 and screw propeller 5, two floating drums parallel 9 about hull 1 below is fixed with by floating drum suspension bracket 2 with hull, the longest length that equals hull of the length of floating drum 9, be shaped as stream line pattern, the buoyancy of two floating drums is enough to dried up of hull holder can be realized minimum drag like this.
On each floating drum, screw propeller 5 is installed in the front portion of floating drum 9, and screw propeller 5 fronts are with fairing 4, and fairing 4 and floating drum 9 are spliced into a spindle shape.
Floating drum 9 inside are divided into two parts, anterior compartment is a power bin 8, power bin is a fully enclosed warehouse, the inside is equiped with direction reverser 7, and screw propeller 5 is contained on the output shaft 6 of direction reverser, and the suspension bracket 2 that the input shaft 3 of direction reverser passes floating drum is connected rotation with the interior driving engine of hull, the output shaft 6 of direction reverser and input shaft 3 are 90 °, the inside is made up of two cone gears, the rotation of vertical direction is changed into the rotation of horizontal direction, drives screw propeller 5 and rotates.
The rear portion of floating drum 9 is buoyant cabins, in order to produce buoyancy.
Screw propeller 5 diameters be floating drum 9 diameters 1.5-2 doubly, can make the current at screw propeller rear portion be attached to the floating drum surface flow like this, floating drum plays this part current rectification, reduces the effect of eddy current.
The cross-sectional plane of floating drum suspension bracket 2 is oval, to reduce resistance.
