Description

FIELD OF THE INVENTION

The invention relates to transport shipbuilding and can be used to create high-speed vessels, especially boats and small vessels.

The problem of creating high-speed floating means is the change in resistance to movement along the surface, which increases with increasing speed in the quadratic and even cubic dependence. To solve this problem, we use a method and device for creating optimal bottom structures, forced air gap between the bottom and the surface of the water, installation of a conveyor belt and at least two drums under the bottom of the vessel. In the manufacture of the bottom using materials and processing, contributing to the reduction of the friction force of the vessel against water.

State of the art

A known method of creation and design of the nose bulb (RF patent for the invention No. 2514964, publ. 03/27/2013), containing the right and left side of the hull, deck, bow, while the bow is made in the form of a bulb. Known US patent No. 5819677, publ. 10/13/1998, to create a nasal bulb. The well-known "Redan boat with a water-jet propulsion" (RF patent for the invention No. 2519303, publ. 06/10/2014), comprising a hull with sharp contours, transom stern and keel bottom, in which a transverse redan is made.

The disadvantage of these solutions is significant hydrodynamic drag and poor ship streamlining conditions.

Known patents of Great Britain No. 1173335, publ. 12/10/1969, France No. 1510301, publ. 01/19/1968, containing fans for creating an air cushion.

The well-known "Method of creating emphasis on a hovercraft and a vessel for its implementation" (WO2013100778A1, publ. 04.07.2013). The method of creating an emphasis on water is based on the fact that the emphasis of the vessel is made in a drop of air-water aerosol created by a compressor located on a vessel with special channels flying above the water by means of compressed air leaving the air cushion.

The disadvantage of this method is that the emphasis is on droplets of water flying above the water by means of compressed air leaving the air bag. The effectiveness of this method is low due to large energy losses due to sliding friction of the air cushion and friction of the vehicle parts against water. In addition, the creation of a compressed air installation, a spray-forming installation, and removal of a part of the air flow from the air screw when forming an air cushion is required.

Known patents and applications: China CN 101704402 A dated 05/12/2010; CN102211654 A dated 12/10/2011; Japan JP 2002316694 from 10.29.2002; Europe EP 2189368 A1 dated 05/26/2010; US No. 6.116.176 dated 09/12/2000, where the vessel is supported by water through a conveyor belt moving relative to the vessel, which tends to a stationary state relative to the surface of the water.

The disadvantage of these solutions is the difficulty in controlling the vessel in connection with a significant reduction in friction when the tape touches the surface of the water. Loss of maneuverability of the vessel negatively affects its operational performance.

Also known application "Device for reducing friction against water" WO2004037636 (A1), publ. 05.06.2004, selected as a prototype, containing in various versions: a conveyor belt having at least two drums under the bottom of the vessel on the truss with a mounting rail to the hull, shock absorbers and a rotation drive through a bevel gear to one drum; two conveyors on both sides of the vessel, located symmetrically relative to the longitudinal axis of the vessel; including conveyor belts with transverse slats to increase resistance during belt drive, etc.

The disadvantage of this device is the low maneuverability and the lack of an effective way to change the direction of movement. Changing the direction of movement of the vessel with the planing mode is difficult, since the efforts of the interaction of the vessel with the surface of the water are minimized.

Disclosure of invention

The declared “Method of creating an emphasis between water and a vessel of increased maneuverability” is based on the task of reducing the sliding friction losses, to create traffic conditions that ensure maximum efficiency of maneuvering.

The technical result achieved during the implementation of this method is the elimination of friction of the sliding of the vessel on the surface of the water when performing maneuvers. In this case, sliding friction in the direction of motion is replaced by rolling friction. The work of sliding friction forces is used to increase the efficiency of maneuvering by changing the direction of the water reaction.

The proposed method improves energy efficiency when moving a ship at significant speeds both in a straight line, during acceleration and stop, and when changing the direction of movement.

The specified technical result is achieved by the fact that the method of creating an emphasis between water and a vessel of increased maneuverability using a conveyor, in which the lower part of the belt is stationary relative to water, and according to the invention, the emphasis between water and a vessel is carried out using two conveyors with independent change of their position relative to the vessel and kinematics of motion.

The supporting part of the tape is divided into two parts, and each part is made on its own frame, capable of independently changing the position in space relative to the hull and the kinematics of movement.

The independent position of each part of the tape in space changes the pattern of movement and force interaction of the vessel through the tapes against water and contributes to the organization of effective maneuvering of the vessel.

A comparative analysis of the proposed solution with the prototype shows that the claimed method differs from the known one in that an individual change in the position of the frame with the tape in space and the kinematics of movement allows you to use changes in the force of the lower part of the tape with water when maneuvering the vessel along the water surface, as well as when accelerating and braking with minimal friction loss.

Thus, the claimed method meets the criterion of "Novelty."

Known technical solutions, where there are devices in the form of specially installed surfaces that contribute to the completion of certain maneuvers of the vessel. The application of the proposed method when maneuvering the vessel meets the criterion of "Industrial applicability".

The effectiveness of the proposed method for increasing the maneuverability of the vessel with fundamentally new possibilities for regulating the intensity of maneuvering, changing the magnitude of the force of interaction with water and its direction with minimal losses of supplied energy is due to the ability to change the position of the tape surfaces in space.

The organization of the impact on the vessel by water reactions through the surfaces of the belts in various directions corresponds to the need for maneuvering at high speeds.

For the first time, the authors formulated methods for changing the position of support tapes and motion kinematics in space, which ensure the action of forces of different modulus and direction to the ship during maneuvers, which meet the criterion of "Inventive step".

In addition, the interaction of water with a moving belt on rolling bearings significantly reduces sliding friction losses when the nature of the vessel’s movement changes; the consumption of supplied movement energy is significantly reduced, especially at high speeds.

The claimed method of creating an emphasis between water and a vessel of increased maneuverability differs from the prototype in that, due to a change in the moving tapes of the emphasis in space and the kinematics of the movement to preserve their interaction with water, increased maneuverability of the vessel at high speeds with minimal loss of supplied energy is provided.

The implementation of the invention

The features distinguishing the claimed solution from the prototype are explained using the scheme of the device with the stops shown in FIG. 1-3.

The device comprises a ship hull 1, a right conveyor 2, a right front adjustable suspension 3, a right rear adjustable suspension 4, an inner right front adjustable suspension 5, an inner right rear adjustable suspension 6, a thrust right part of the belt 7, an inner left front adjustable suspension 8, an inner the left rear adjustable suspension 9, the left conveyor 10, the outer left front suspension 11, the outer left rear suspension 12, the persistent left side of the belt 13.

The device operates as follows. At the beginning of the movement, the hull 1 of the vessel is immersed in water; to enter the high-speed mode, four front adjustable suspension (pos. 3, 5, 8, 11, Fig. 3) are shortened; the surfaces 7 and 13 of the part of the belts of the conveyors 2 and 10 change the angle of inclination, turning relative to the axis y ', and contribute to the accelerated lifting of the hull 1 of the vessel; (the rear suspensions 4, 6, 9, 12 of Fig. 3 can also be extended and the conveyor is additionally rotated about the y axis); when turning to the left, two internal suspensions (pos. 5, 6, Fig. 3) are lengthened and the right conveyor (pos. 2, Fig. 1) rotates about the x 'axis and creates additional resistance to skidding of the vessel; when turning in the opposite direction, the internal suspension is lengthened (pos. 8, 9, Fig. 3); for emergency braking, the front part of the left 10 and right 2 conveyors is lowered (the suspensions of pos. 3, 5, 8, 11, Fig. 3 are lengthened) and the rear suspensions (pos. 4, 6, 9, 12, Fig. 3 can be shortened at the same time) . Necessary and sufficient for position adjustment are three adjustable suspensions on each conveyor with one fixed point on the ship's hull.

Such a “Method of creating an emphasis between water and a vessel of increased maneuverability” was not found in existing technical solutions for the emphasis of the vessel. The “method of creating emphasis between water and a vessel of increased maneuverability” is advisable to use when using the vessel at speed to improve maneuverability.

In the considered method, the operating conditions of the vessel with minimal losses due to sliding friction and the use of rolling friction when performing various modes of movement are created. The use of water reactive forces when performing maneuvers will change the trajectory of the vessel more efficiently. The use of moving belts in various versions of the positions of the conveyors optimizes the technical and economic performance of the vessel. In addition, the drive of rotation of the conveyor belts can be used to differentiate the movement of the belts along the curved path of the vessel.
