Description

FIELD OF THE INVENTION

The invention relates to the shipbuilding of high-speed vessels, especially boats and small vessels.

State of the art

The invention (according to the "Method for creating an emphasis between water and a vessel of increased maneuverability" No. 2646005, published on 02.28.2018) relates to the shipbuilding of high-speed vessels, especially boats and small vessels.

The change in resistance to the movement of ships on the surface of the water with increasing speed increases in quadratic and even cubic dependence and is a problem when creating high-speed swimming equipment. To solve this problem, in the manufacture of the bottom of the vessel using special materials and processing that contribute to reducing the friction force of the vessel against water; using a method and device for creating bottom structures of an optimal shape, forcing an 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.

Known patent for the invention of the Russian Federation No. 2514964, publ. 05/10/2014, containing the right and left side of the hull, deck, bow, which is made in the form of a bulb. Known US patent No. 5819677, published October 13, 1998. to create a nasal bulb. The well-known "Reduced boat with a water-jet propulsion" patent for the invention of the Russian Federation No. 2519303, publ. 06/10/2014, containing a housing with sharp-cut contours, transom stern and keel bottom, in which a transverse redan is made.

The disadvantage of these solutions are significant friction losses, significant hydrodynamic drag and poor vessel streamlining conditions.

The well-known "Method of creating an emphasis on a hovercraft and a vessel for its implementation" (W02013100778A1, published 04.07.2013), which is based on 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 over water through compressed air coming out of an air cushion.

The disadvantage of this design is that the emphasis is made in a drop of water flying above the water by means of compressed air leaving the air cushion, with large losses of energy due to friction sliding of the air cushion and vehicle parts against water. In addition, the installation of creating compressed air, a spray-forming installation, the removal of part of the air flow from the screw during the formation of the air cushion is necessary.

Known patents and applications: China CN 101704402 A dated 05/12/2010; CN 102211654 A dated 10/13/2011; Japan JP 2002316694 from 10.29.2002; Europe EP 2189368 A1 dated 05/26/2010; US No. 6.116.176 dated September 12, 2000; where the vessel rests on 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 decisions is the inefficient control of the vessel with a significant reduction in friction when touching the bottom of the tape surface of the water. Loss of maneuverability of the vessel negatively affects operational performance.

It is also known "Device for reducing friction against water" WO 2004037636 (A1) from 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 a farm 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 driving modes, especially with the planing mode, since the interaction force of the vessel with the water surface is minimized. Another disadvantage is the significant movement of the vessel with low sliding friction and, as a result, the insufficient efficiency of maneuvering when the vessel is moving.

Disclosure of Invention

The claimed device for creating an emphasis between water and a vessel of increased maneuverability is based on the task of reducing the sliding friction losses, to create maximum maneuvering efficiency when the vessel is moving.

The technical result achieved in the proposed device is the elimination of friction sliding surface of the vessel on the surface of the water when the direction of movement changes.

In this case, the sliding friction of the vessel on the surface of the water is replaced by the rolling friction of the surface of the conveyor. The work of sliding friction forces is used for the efficiency of maneuvering by changing the direction of the reaction of water on the unfolded surface of the conveyor belt.

The proposed device increases the use of energy when moving the ship at higher speeds in a straight line, during acceleration and braking, and when changing the direction of movement.

The specified technical result is achieved by the fact that the device for creating an abutment between water and a vessel of increased maneuverability uses two conveyors in which the lower parts of the belt can be stationary relative to the surface of the water, and according to the invention, the abutment between the water and the vessel is carried out using two conveyors with an independent change in their position relative to the ship and the kinematics of movement.

The supporting part of each of the two parts of the tape is made on its frame with the ability to independently change its position in space relative to the body and the kinematics of movement.

The independent position of each belt in space determines the force interaction on the vessel through the reaction of the belt on water and changes the pattern of movement of the vessel when organizing effective maneuvering of the vessel.

A comparative analysis of the proposed solution with the prototype shows that the claimed device differs from the known one in that an independent change in the position of the frame with the tape in space allows you to use the module and direction efforts of the water surface on the lower part of the belt when performing a maneuver of the vessel on the water surface, as well as braking and accelerating the movement of the vessel with a reduction in friction losses.

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

Known technical solutions, where there are specially installed surfaces that contribute to the completion of the given maneuvers of the vessel. The use of the claimed device to improve the maneuvering of the vessel meets the criterion of "Industrial applicability".

The effectiveness of the proposed device to increase the maneuverability of the vessel is achieved by fundamentally new possibilities for regulating the intensity of the maneuver, changing the magnitude and direction of the force of interaction with water with minimal loss of energy supplied due to the ability to change the position of the tape surfaces in space.

The organization of the action on the vessel of the water reaction through the surfaces of the belts in various directions corresponds to the need for maneuvering at high speeds, especially in planing mode.

For the first time, the authors proposed a device for changing the position in the space of support tapes and kinematics of movement, which ensure the action of forces on the vessel that are different in modulus and direction when performing a maneuver, which meets the criterion of "Inventive step".

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

The claimed device for creating an emphasis between water and a vessel of increased maneuverability differs from the prototype in that due to a change in the space of the moving belts of the emphasis and the kinematics of movement, the preservation of their interaction with water, increased vessel maneuverability is provided, especially at high speeds and minimal losses of supplied energy.

The implementation of the invention

The features distinguishing the claimed device from the prototype are explained with the help of the device diagram of the vessel with stops shown in FIG. 1-3 and the suspension scheme of the rigid attachment to the hull of the vessel shown in FIG. 4.

The device comprises a ship hull 1; right conveyor 2; adjustable front suspension 3; adjustable right rear suspension 4; adjustable inner right, rigidly connected to the hull of the vessel, front suspension 5; adjustable suspension 6; persistent right side of the tape 7; adjustable inner left, rigidly connected to the hull of the vessel, front suspension 8; adjustable inner left rear suspension 9; left conveyor 10; outer left pendant 11; outer left rear suspension 12; the persistent left side of the tape 13; hard bracket 14; cylinder 15; the supporting surface of the piston 16; stock 17; lower abutment surface 18; the upper node 19 of the cardan rotation; the lower node 20 cardan rotation; the attachment point of the frame 21 of the conveyor; right transverse suspension cylinder 22; rear bracket 23; left transverse suspension cylinder 24; left outer suspension assembly 25; the right outer suspension assembly 26.

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, the front adjustable suspension (pos. 3, 5, 8, 11 of Fig. 3) are shortened; surfaces 7 and 13 of the lower part of the conveyor belt (pos. 2, 10 of Fig. 3) change the angle of inclination, turning relative to the y 'axis and contribute to the accelerated lifting of the hull 1 of the vessel; at the same time, the rear suspension (pos. 4, 6, 9, 12 of Fig. 3) can be lengthened and the conveyors (pos. 2, 10 of Fig. 3) can also be turned relative to the y axis, activating the lift; when turning to the left, two internal suspensions (pos. 5, 6 of Fig. 3) are lengthened and the right conveyor (pos. 2 of Fig. 1) rotates about the x 'axis and creates additional resistance to skidding (you can activate skidding resistance by turning the left conveyor (pos. 10 Fig. 1, 3)); when turning in the opposite direction, the internal suspensions are lengthened (pos. 8, 9 of Fig. 3) and the right conveyor 10 is rotated (at the same time, the left conveyor 2 can be used); for emergency braking, the front of the left conveyor 10 and the right conveyor 2 are lowered (the suspensions (pos. 3, 5, 8, 11 of Fig. 3 are lengthened) and the suspensions (pos. 4, 6, 9, 12 of Fig. 3 can be shortened at the same time).

The transfer of force from the vessel to the transporters and the braking force from the conveyors to the vessel during spherical movement of the conveyors relative to the point of the vessel is carried out through the suspension 5 (Fig. 1) of the right conveyor 2 (Fig. 1) and the suspension 8 (Fig. 1) of the left conveyor 10 (Fig. 1).

Conveyors 2 and 10 (Fig. 1, 3) are able to make spherical motion relative to the hull 1 of the vessel. To fix the axis of the conveyors parallel to the movement relative to the vessel, a bracket is installed in its rear part (pos. 23 of Fig. 4). The right cylinder (pos. 22 of Fig. 3) moves the back of the right conveyor (pos. 2 of Fig. 3), and the left cylinder (pos. 24 of Fig. 3) moves the back of the left conveyor (pos. 10 of Fig. 3) and provides preset position of the conveyors (pos. 2, 10 of Fig. 3) relative to the housing (pos. 1 of Fig. 1, 2).

Necessary and sufficient to adjust the position of the conveyors relative to the hull are three adjustable suspensions on each conveyor with one fixed point on the ship's hull.

Such “Device for 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 “device for creating an emphasis between water and a vessel of increased maneuverability” is advisable to use when using the vessel at high speeds to improve maneuverability, especially when the vessel glides on the surface of the water.

The considered device creates the operating conditions of the vessel with minimal loss of sliding friction and the use of rolling friction when performing various modes of movement.

The increase in water reactive forces when performing maneuvers, the trajectory of the vessel will change more efficiently. The use of moving belts in different positions of the conveyors optimizes the technical and economic performance of the vessel. In addition, the differential drive of the belts along curved paths can be used in the conveyor belt rotation drive.
