Abstract
The utility model belongs to the field of ship manufacture, in particular to a ship with propellers exerting force bidirectionally. The propellers are installed at the middle-lower portions of two sides of a boardside. Sleeves are arranged on the excircles of the propellers, and water inlets of the sleeves are provided with mesh enclosures. Compared with a traditional ship, the speed of the ship with the propellers exerting force bidirectionally is improved by one time, and energy sources are greatly saved.
Description
Technical field
The utility model belongs to system bateau neck territory, relates to a kind of boats and ships that can make the screw propeller bidirectional force applying specifically.
Background technology
Since boats and ships were realized power machineization, propeller for vessels just was installed in stern always, and the recoil thrust of dependence screw propeller promotes boats and ships and advances.This installation method is used till today always.And can only being screw propeller, in fact existing this method for installing screw propeller produces the unidirectional application of force.Screw propeller acting has only utilized half the, and second half then is having slatterned in vain.Its actual drawback of bringing is exactly: waste energy, ship's speed is crossed low and safety is not high.
Summary of the invention
The purpose of the utility model is to provide a kind of boats and ships that can make the screw propeller bidirectional force applying, can only do one-way force applied shortcoming with the screw propeller that overcomes traditional boats and ships, makes full use of the screw propeller acting, saves the energy.
The utility model is realized through technical scheme once:
A kind of boats and ships of screw propeller bidirectional force applying comprise fore, stern 12, ship side 13 and screw propeller 2, said fore, stern 12, the ship side 13 common hulls of forming, and it is characterized in that: said screw propeller 2 is installed in the middle and lower part of ship side 13 both sides.
Further, in the technique scheme, said screw propeller 2 is installed on the ship side 13 position near fore.
Further, in the technique scheme, the outer ring of said screw propeller 2 is provided with sleeve 4, and the bore of said sleeve 4 water inlets is slightly larger than water outlet aperture.
Further, in the technique scheme, the water inlet of said sleeve 4 is equipped with guard 5.
The beneficial effect of the utility model is: the screw propeller bidirectional force applying, improved efficiency of energy utilization greatly, and simultaneously boats and ships are raised speed greatly, and safety is higher.
Description of drawings
Fig. 1 is the structural representation that the utility model ship side formula is installed;
Fig. 2 is the planar rear view that the utility model ship side formula is installed;
Fig. 3 installs the structural representation of screw propeller installing sleeve for the utility model.
The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
Like Fig. 1, shown in Figure 2, the specific embodiment of the utility model is installed in the middle and lower part of ship side 13 both sides with screw propeller 2, and screw propeller 2 rotates and produces attractive force and recoil thrust simultaneously, promotes boats and ships and advances.Wherein the installation site of screw propeller 2 is preferably at the position near fore, the strong like this resistance of dissolving the fore current, more effective energy-conservation with improve the ship speed of a ship or plane.Screw propeller 2 is installed in parallel in ship side 13 both sides, makes the power can balance, guarantees that boats and ships balance safety advances.
Further, screw propeller 2 is installed in the position near fore, suitably near fore, the favourable fore of dissolving hinders shock wave, the energy-conservation and raising ship speed of a ship or plane.When screw propeller 2 rotated, the current of fore were taken out to stern 12 by a large amount of, fast speed at once.At this moment the water level of fore and hydraulic pressure all are lower than stern 12, and this flow of water difference advances with ship always and appear at fore all the time, attract ship forward; Description water according to the Reynolds number convection cell has stickiness, and this stickiness makes current become the integral body that an ability involves a little less than each other.Therefore when screw propeller 2 rotates moving and takes out the water of fore to stern 12 fast; The one side fore resistance relative with aquatic product; It is poor that the flow of water of favourable ship's navigation also appears in then generation is bigger on the other hand suction dragline gravitation simultaneously, moves ahead thereby constantly draw boats and ships.
Simultaneously, current are constantly discharged, and produce recoil thrust, promote boats and ships and move ahead.This is the principle of work of existing ship.But the screw propeller of existing ship is to be placed in stern, has sheltered from the front portion of screw propeller, thereby has only the tractive force that recoils thrust and do not have to bring like the utility model.
In addition, as shown in Figure 3, the outer ring of screw propeller 2 can add a sleeve 4 in the above-mentioned embodiment, similar properller, and its water inlet is slightly larger than water outlet, and its ratio is approximately 10: 8.When screw propeller 2 high speed rotating were done work, current were because of going out the young more powerful ejection generation recoil that obtains compressing; Because the orientation of sleeve 4 is arranged, make oar application of force direction place best angle, the sleeved water guide of its attractive force seems more strong, also can help ship constant-bearing navigation wind-proof and wave-proof, eliminates current and partly hinders power.
Secondly the water inlet at sleeve 4 adds a guard 5, can prevent that like this screw propeller 2 from being twined, breaking by foreign material etc.
[0019] the utility model, is compared with traditional dummy ship in the identical time through the model ship test, and speed is doubled, and is energy-conservation half the.
