The specific embodiment
The proposition of bidirectional force applying spiral prize installation method is to carry out in the realistic model repetition test than standard, with the application of reality be numerous tube, the branch of size, quantifications does not have essence other, its principle is the same, is reliable mature technology.About propeller for vessels the bidirectional force applying effect is arranged when doing work, single based on above experiment, and by model ship test affirmation.The proposition of this programme at first is from the investigation to existing power driven vessel.When the ship on resting in harbour need cast off wharf, often make the screw propeller counter-rotating, allowing ship retreat rotary head again leaves, why can the screw propeller counter-rotating make ship retreat? we know that screw propeller is when just changeing, its oar leans against stern, screw propeller towards outside, screw propeller is just being changed a job when doing, the screw propeller face says that the recoil pull power that is subjected to water is advanced ship.But when screw propeller reversed, its draining had turned to stern and stern has directly been produced anti-impulsive contact force, and at this moment Jiang recoil kinetic energy is zero.According to application force in the mechanics and antagonistic force principle, the recoil pull power of the water that propeller is subjected to is offset by the anti-impulsive contact force of stern, from existing ship is retreated, and this is general mechanics general knowledge.Since it is so, is that what power retreats ship? unique answer is that the water inlet back side of screw propeller produces, and this attractive force is returned ship backward.The insider is familiar with to some extent and uses the positive anti-application force of doing that produces of the water of screw propeller since the dawn of human civilization, but equal traction, suction pulling force that the back of the body per mu yield of screw propeller is given birth to are then ignored fully, and this is a very big error.
Do an introduction in detail with regard to the technical solution of the utility model with reference to the accompanying drawings, and utilize shown in Figure 1 the contrast to be illustrated with the existing ship screw propeller.This " bidirectional force applying propeller " mentioned in the place ahead is the constructing technology of quoting the existing ship screw propeller substantially, and different is that the existing ship screw propeller is the afterbody that is placed in ship, and this " bidirectional force applying propeller " then is the lower position that is placed in the forward quarter ship side.Optimal way of the present utility model is at position, hull the place ahead, a diameter is set can holds " metallic conduit " of this ship screw propeller down.Pipeline enters from hull the place ahead, and in hull behind the certain-length, two direction branches to the left and right from hull port and starboard pass-out rearward, are communicated with the water of ship port and starboard.Its pipeline is smaller in two outlet bore sums of ship port and starboard, and the ratio of general water inlet cross section and two outlet sums is about 3 to 2.In this pipeline, settle screw propeller near the water inlet suitable position, to settle screw propeller to be because the attractive force that screw propeller produces when doing work is not singly pointed to water inlet near the water inlet, but all inside pipe walls, the screw propeller preceding pipeline is long will to disperse this attractive force.Consider that as hull is long front and back are provided with flow velocity and decompression that twin screw (screw propeller is respectively pacified in front and back) is accelerated water.Also have a bit and settle a guard in case in the foreign material inlet pipe road at water inlet exactly.
The setting of screw propeller sleeve, its purpose are exactly in order to make screw propeller better bring into play the effect of its bidirectional force applying.Its concrete structure is as shown in Figure 1:
Below the water surface of the fore 1 of common boats and ships a screw propeller sleeve 4 is set, the water inlet of this screw propeller sleeve 42 leads to outboard from fore; Near the position of wearing fore screw propeller 3 is set in the screw propeller sleeve 4, screw propeller sleeve 4 extends in boats and ships behind the segment distance backward, both sides extend to screw propeller sleeve left side arm 10 and the right arm 9 of screw propeller sleeve to the left and right again, the left side water outlet 5 and the right side water outlet 6 of left side arm 10 and right arm 9 lead to the rear of outboard respectively from the port and starboard of boats and ships, propeller drive shaft 7 is supported by transmission axle bed 8, drives screw propeller 3 work.
Transformation for convenient existing ship screw propeller and bidirectional force applying, can be on the intact basis of existing ship inner structure, whole propeller sleeve 2, left and right sides manifold system and screw propeller 3 are placed in bottom of ship, below described fore bottom, extend back, water inlet (2) is arranged on the fore direction, left side arm (10) and right arm (9) stretch to the hull both sides, and described screw propeller (3) is arranged in the screw propeller sleeve (4).This structure is brought into play the effect of bidirectional force applying equally.
Said structure be except can bringing into play the effect of its bidirectional force applying, also favourable with dissolve fore and hinder shock wave, energy-conservation and improve the ship speed of a ship or plane.Propeller installation in the wings, the fore in the place ahead is compressed water level and increases and form the violent obstruction shock wave of one deck.At bidirectional force applying oar type ship head of the present utility model, even it is right that ship navigates by water in high speed, above obstruction shock wave can not appear yet, this be because this fore screw propeller pipeline in time fast with the left and right sides of hydraulic pressure to ship, travelling forward under the strong potential difference effect of low water and stern high water level on the bow of opposite low water, boats and ships appears in fore on the contrary.It is that the attractive force of fore can favourable ship coursekeeping that bidirectional force applying propeller also has an effect, resists more by force to impact from various degree stormy waves and improves the safety of navigation coefficient.It has avoided the deficiency of screw propeller outside hull, can eliminate the preceding obstruction shock wave of fore the most intuitively, produces low water, and the flow of water of low pressure is poor, favourable ship hyper-speed navigation, energy-conservation.
