Abstract

A propeller with sleeve barrel for ship features that the propeller is arranged in a sleeve barrel whose diameter is consistent with that of propeller, said sleeve barrel is fixed to the ship tail under ship body, and a protecting net is arranged between sleeve barrel and ship bottom. The rotating propeller can generate a cylindrical water stream for increasing speed of ship. Said protecting net can prevent the propeller from being wound by other material.

Description

Telescopic screw slurry propelling unit
(1) technical field
The present invention relates to all kinds of ship domain waterborne, especially relate to a kind of boats and ships and starch propelling unit with telescopic screw.
(2) background technology
All boats and ships propeller all are installed in the below of hull afterbody by open ground at present, and its principle of work is: utilize the rotation of propeller ramp blade, the reaction thrust of the water that is generated when pushing water to rear is pushed forward hull.What at this moment propeller was rotated is fast more, and the reaction thrust of the water that it generates is just big more, and travelling of hull is also just fast more.But propeller is when work done, also there is the phenomenon of waste power to exist, existing propeller all is made up of three inclined-plane blades, when they rotate in water, it is the parallel water column of expansion that water is pushed into a cone, with the water fast and parallel push the rear to, at this moment, the parallel water column of the cone that in water, flows fast, stopped by water cross section with respect to it, make it can't wash a water channel apace open, also give the powerful repulsion power in bottom surface of this parallel cone that flows fast simultaneously relatively, this application force is fed back on the whole cross section of rotating propeller, forcing propeller to retreat, and propeller is the below that is fixed on the hull afterbody, and propeller is driving hull and moves forward thus.From we are not difficult to find out here, rotation by propeller, after the developed surface that water is become a cone is released backward, at this moment with respect to the water surface of this cone basal cross section, as having become " waterwall " together, also promptly given its same repulsion power (comprising the consumption that water is mobile) by the homalographic of this cone basal cross section, and at this moment, the repulsion power of this cone basal cross section, really can feed back on the propeller cross section, a center part of also having only this cone basal cross section, the repulsion power around other has all been made invalid power and slatterned, and therefore says: existing propeller has the phenomenon of waste power to exist! Be contained in the below of hull afterbody by open ground as it existing propeller, when hull travels, can be hindered thing to break frequently and twined by some fish, algae, mobile foreign material, make it can't rotate or reduce thrust, needing thus to send someone frequently, diving keeps in repair or cleaning, results in hand cramps to people.
(3) summary of the invention
The objective of the invention is to utilize a kind of simple mechanism, under power unmodified situation, increase the power of existing propeller, improve the route speed of boats and ships, solve phenomenons such as existing propeller is broken often, winding simultaneously, propeller can need not be repaired and clear up for a long time.
The object of the present invention is achieved like this: peripheral the increasing of existing boats and ships propeller is provided with a sleeve consistent with propeller blade equal diameters, length successively bore and propeller diameter and a protection purse seine, simultaneously the final rotational structure of existing propeller is changed into the independent steering casing of long period of soaking in water, during installation, with entire sleeve propeller propelling unit, be fixed on hull afterbody below, can reach the purpose of protection, speedup.
The invention has the advantages that, owing to will add a sleeve that equates with propeller equal diameters length, front and back bore around the propeller, the taper that forces existing propeller produce launches water column, change over the parallel water column equal with the propeller area, repulsion power with the water of its former cone bottom surface, concentrate on the sleeve outlet perpendicular to propeller, make its repulsion power be used to fully promote among propeller steps back, thereby improve advancing fast of hull! Simultaneously; because this design is to have increased a sleeve around existing propeller; therefore a foreign material grille guard has been installed on this sleeve simultaneously; thereby protected propeller can not clashed into and be twined by foreign material; reduce the maintenance and the cleaning of propeller, and prolonged service life greatly, simple and practical; respond well, be beneficial to popularization.
(4) description of drawings
Fig. 1 is the lateral plan that the present invention is installed in hull afterbody below;
Fig. 2 is back view and the A-A view that the present invention is installed in hull afterbody below.
1 is to go along with sb. to guard him sleeve among the figure, the 2nd, and power rotation axis, the 3rd, protection purse seine, the 4th, hull base plate, the 5th, propeller blade, the 6th, power steering casing, the 7th, power steering gear, the 8th, adapter plate, the 9th, fixed muffle connecting rod.
(5) specific embodiment
The present invention is described in further details with most preferred embodiment below in conjunction with accompanying drawing:
The present invention is by propeller, go along with sb. to guard him sleeve (1) and protection purse seine (3) formation, it is long identical with the propeller diameter to go along with sb. to guard him sleeve (1), front and back bore unanimity, its top is fixed on the hull base plate (4) by adapter plate (8), fixed muffle connecting rod (9) with the S. A. at propeller center part with go along with sb. to guard him sleeve (1) and be connected, propeller rotating shaft and fixed muffle connecting rod (9) joining part, be provided with a power steering casing (6), power rotation axis (2) upper end is fixedly installed on hull base plate (4) position, its lower end is by the gear transmission of the power steering gear (7) in the power steering casing (6), drive propeller blade (5) rotation, protection purse seine (3) is arranged on goes along with sb. to guard him between sleeve (1) and the hull base plate (4).

Claims (4)

1, telescopic screw slurry propelling unit, it is characterized in that it by propeller, go along with sb. to guard him sleeve (1) and protection purse seine (3) constitutes, go along with sb. to guard him sleeve (1) and be socketed in the propeller periphery, and be fixedly linked by adapter plate (8) with hull afterbody base plate (4), protection purse seine (3) is arranged between sleeve (1) and the hull base plate (4).
2, telescopic screw slurry propelling unit as claimed in claim 1, it is characterized in that described propeller rotating shaft part, can be provided with power steering casing (6), the upper end of power steering axle (2) is located at hull base plate (4) position, the lower end is located in the power steering casing (6), by the gear transmission of power steering gear (7), drive the propeller rotation.
3, telescopic screw slurry propelling unit as claimed in claim 1, tool is characterised in that goes along with sb. to guard him between sleeve (1) and the hull base plate (4), also can be provided with fixed muffle connecting rod (9) and fix.
4, telescopic screw slurry propelling unit as claimed in claim 1 is characterized in that the described sleeve (1) of going along with sb. to guard him is consistent with propeller blade (5) equal diameters length, front and back bore and propeller diameter.
