Vessel with blade paddle wheels

FIELD: transport.

SUBSTANCE: stern of vessel with blade paddle wheels is made as two through water-flow channels dividing bilge into three water displacing sections. On vertical walls of water-flow channels bearings of two driving shafts with paddle wheels are installed. The paddle wheels consist of two parallel to each other solid disks with blades installed between them which blades are located on several heterodistant diameters. When wheels are rotating the blades move one after another in groups decanting water on more distant from shaft blades ensuring bumpless entrance in water at an angle of 45 degrees for them. At an exit from water, angle of blade inclination to horizon ensures accelerated water discharge under water for them.

EFFECT: creation of vessel with propulsor having large hydraulic cross-section ensuring bumpless entrance into water, absence of wave at an exit from water, creation of large support for vessel both in deep water and draft is restricted, possibility to use impact pressure of water counter flow.

Our country has the largest and most extensive network of waterways. Currently mastered no more than 10 percent of their length. But in the uncharted territories are the main natural wealth of the country. That is why currently made a decision to learn a wealth of Siberia and the Far East.

Outdated river fleet requires immediate construction of a powerful, modern river fleet high capacity, ability to operate in deep water and in shallow water. Complicate the task as a contamination of rivers and turbulent flow on small rivers and Slough ice and wave formation in the Northern latitudes, in the mouths of the Siberian rivers. In the European part of the country require expensive dredging operations or the creation of new powerful ships, able to work with limited draught.

River / sea vessels able to operate in sea conditions, river conditions are not able to work optimally, as the draught of these vessels is limited by the diameter of the propeller. You must create such a thruster, which would be able to create a strong emphasis on deep water, and under conditions of limited rainfall. Currently, more than 95% of vessels equipped polupogruzhnye screw propellers, which may not work on finely�odier. The cannons have a small pressure section and a low efficiency and therefore can't be installed on heavy courts. Paddle wheels are able to develop great focus, even in shallow water, but they work only at 40-50 rpm. The same engine goes the way of increasing the number of revolutions, and these conflicting requirements are insurmountable. Besides paddle wheels, bulky, heavy, complicated and unreliable in operation. For unstressed of water entering the slots of the wheels do swivel, but then these wheels became 25 times harder and 40 times more expensive. In addition, paddle wheels, creating a large wave over the stern, what is spent on energy. Many scientists shipbuilders, including Nizhny Novgorod Professor M. J. alferiev and N. N. Kabacinski, tried to regulate the flow of water behind them, but their designs were cumbersome and did not find application. Almost all modern engines are based on the principle of the helix, giving a spiral flow at the stern, eroding riverbanks. Nevertheless, more than 150 years the screws have a monopoly position on water transport.

The solution can be found in the development of new propulsion, discarding the water straight back, in the direction opposite to the direction of motion of the vessel. Such attempt was made by me, izobreteny� No. 2391249 dated 10.06.2010

This proposal attempts to improve the above-mentioned invention.

Created by the propeller must:

- to possess a large hydraulic cross-section;

- to provide a shockless entry into the water;

- not to make wave in the water;

- to create a large emphasis to the vessel as in deep water and limited sediment;

- to use the dynamic pressure of the oncoming flow of water.

This can be done when the transverse location of the drive shaft, which can accommodate not one propeller, as the propeller shaft, and several paddle wheels. It is necessary to streamline the flow accelerated water from the water inlet to the water in the feed. Therefore, the device proposed in the stern of the vessel is very different from existing vessels.

A feature of the ship is that the ship's hull 1 aft on the hull is made of two short section of the channels 2 and 3. On the sides and in the middle of the stern there are two side displacement sections 4 and 5 and one middle 6. They provide maintenance afloat propellers 7, 8 and 9, 10 mounted on the leading shafts 11 and 12. Cm. Fig.1, 2.

Drive shafts are fixed on the vertical walls of the channels, on supports with bearings 13, 14 and 15, 16. Effort from the motors 17 and 18 are transmitted to the drive shafts by means of intermediate shafts 19, 20, 21, 22, 23, 24 and bevel gears 25, 26, 27, 2, 29, 30 and 31, 32, 33, 34, 35, 36. Section of the channels in the input have a funnel-shaped inlets 37, 38, grilles fences 39, 40. On the bottom section of the channels is set vodoprylad sheets 41 and 42. At the entrance to the channels is set vodoprylad sills 43, 44, which spraylat swirling water wheels in the horizontal plane. The aft section of open channels. At the exit of the channels on its sides are the feathers of the steering gear 45 and 46. Above them a branch of steering gears 47, which does not allow the discharged stream to rise above the waterline and create a wave.

On top of the deck wheels can be closed with a solid glass cover that will allow tourists to watch the game of spray with the blades of the wheels, illuminated by colored floodlights. The impeller is made of planar parts. On the device it is extremely simple. I wheel no hub. Cm. Fig.3, 4. The wheels 48 are bolted to power the coil 49 on its sides. The coil itself is mounted on the splined drive shaft. If necessary, the drive shaft can be manufactured in the form of a hexagon. Then the holes in the coil must have the same shape. The blades 50 are fixed between two parallel disks. This allows you to place them on several diversity-remoted from the shaft diameters. All blades on dis�Ah are they provided input into the water at an angle of 45 degrees. It can provide a shockless entry into the water, and the accelerated release of water below the waterline. The blades of the diversity-remoted diameters are grouped in several groups, where they at rotation follow each other at short distance, passing the stream of water on the blades of the more remote orbits. Water with the blades straightening large diameter bottom leaves and thrown over the stern. Fig.2 and 3 show two coaxial wheels, the blades of which are located along two diameters of the diversity-remoted. The circumference of the blades are grouped in six groups. Wheels can be made with blades located on 3, 4, 5 or more diameters. Therefore will change as the number of blades in one group, so the number of groups on the disc. Fig.2 shows the arrangement of two propulsion systems, located at different sides of the ship. This allows you to have a good ship handling and maneuverability. The fastening of the blades on the discs allows you to place the blades in several diversity-remoted from the center of rotation diameters, which ensures efficient operation of ships under different rainfall conditions. Transverse drive shafts allows you to obtain a large area of the blades simultaneously working in channels section that provides �big emphasis, unattainable by other drivers.

Great emphasis is created on the vessel due to the direction of all accelerated water straight back, in the direction opposite to the direction of motion of the vessel. This is achieved by the ordering of water and its direction in section channels, and by paddle wheels, blades which direct the water only fast ago. The location of the blades on the discs allows them to be positioned so that the flow of water, Express in small orbits, kept the energy and momentum given to the blade more remote from the center of rotation of the orbits. This ensures the transfer of energy of centrifugal force to accelerate the water in the horizontal plane, i.e. for movement of the vessel. When you rotate the wheels the blades enter the water in unstressed mode at an inclination angle of 45 degrees. Subsequent rotation of the wheels for a moment rotates the blades in a horizontal plane, allowing a counter stream to enter the channel section. It does not create resistance to a counter stream. Upon further rotation of the wheels the blades in this group be at an angle to the incident flow of water. Most of the water is accelerated towards the open aft section of the channel. A portion of the water entrained by the centrifugal force shimmers into more remote from the center of rotation of the blade. Middle lobe passes into the water on lapastica remote, which not only accelerates, but also leads the accumulated water in the bilge water the leaves. Further rotation of the vane wheel makes this group vertical. All water is expelled through the open channel. Accumulated on the bottom of the water creates a backwater necessary for the blades to increase the density of water. The creation of backwater helps funnel-shape inlets that accelerate the flow of water due to the energy of a moving ship. When moving against the current funnel accelerates the flow of the energy of velocity head of the river. The density of the water on the blades, accelerating and discharging the water at the stern, significantly increases the efficiency of the paddle wheels. Upon exiting the water the blades are already vertical in the water with them rolled down. The bottom of the steering gear hanging in the channel, does not allow to form volnoobrazovaniye. All expedited water is directed in the direction opposite to the movement of the ship.

The efficiency of the courts with bladed paddle wheels consists of the following advantages:

1. Transverse drive shafts allows you to obtain a large area of the blades, while working in the channels section, which provides a strong emphasis unattainable by other drivers.

2. The fastening of the blades on the discs allows you to place the blades in several diversity-remoted from the center� rotation diameters, which ensures efficient operation of the wheels at different precipitation vessel.

3. Accelerate the flow of water is regulated in section channels and goes from the stern only in the direction opposite to the direction of motion of the ship, expending more energy in his movement.

4. Good security wheels both below and on the sides allows you to create vessels for operation in the littered fairways, a bit of ice and on a rampage. There is no danger of twisting cables for propulsion, like trawlers, minesweepers, tugs, vessels of technical fleet, etc., the Lateral wave is not bare paddle wheels.

5. Section TV placed directly on the bottom of the vessel, does not require the expenditure of energy to overcome the resistance of the water in the pipe when lifted to the pumping device, like a water cannon.

6. Accommodation gross lines above the waterline does not create resistance to the movement of the vessel. Transmission repairs do not require docking the vessel and allows repair of outside plant environments.

7. The ability to work bladed paddle wheels in unstressed and momentumless modes allows the use of modern engines.

The creation of courts with bladed paddle wheels will expand the area served by water transport, to eliminate the overload of work at the entrance to river ports to unload a train and a bus�road mobile, to reduce the need for costly dredging, using only a new design solution. This will give the country a huge economic impact.
