The invention relates to the field of shipbuilding, in particular to small floating means - boats and rafts, including rescue, as well as to the field of their driving mechanisms, in particular to drive the lead screw.

Famous lifeboat with a hard closing, equipped with seats for passengers, engine shafting, steering device, cutting, and landing pads on the roof of the closing, at which boarding hatches are located in the upper part of the hard close and under the landing sites are back hatches for the passage of the exhausted people, fitted caps, openable from the inside and the outside of the boat (see A.S. USSR №395303, M. CL. VS 9/02, lifeboat. Application No. 1498218/27-11 from 14.12.70, publ. 28.08.73. Bull. No. 35).

The disadvantage of this boat is the application to ensure its stroke engine, which is the internal combustion engine.

Also known lifeboat with the device to ensure its progress, consisting of a lead screw, drive motor, battery and generator of electric current containing a rotor and a stator with a horizontal common longitudinal axis, the stator or rotor which is fixed in the boat, and pair them with the rotor or the stator is set free from the other drive units, with the possibility of fluctuations around the VOA axis from acting on the boat waves of water, why the rotor or the stator is made of a statically unbalanced due to the different variants of the eccentric displacement of the center of the mass about an axis of rotation and their positioning on the boat (see Russian Federation Patent for the invention №2397104 IPC VS 9/02. Lifeboat with the device to ensure its progress and its indirect application. Application No. 2009100835/09 from 12.01.09. Auth. Fig. Nastasenko VA // BI No. 23 dated 20.08.10).

The disadvantage of this boat is a low power electric generators at the expense of low speed rotor or stator, generating an electric current, a very high complexity and cost of the generators, as well as losses on the conversion of mechanical energy waves into electrical and then back into mechanical energy of rotation of the driving motor and driven them into the movement of the lead screw.

The purpose of this invention is the simplification of the device to ensure the progress of the boat and the exclusion of conversion of mechanical energy of the waves into electricity, and Vice versa, by means of kinematic connection of the shaft lead screw through put with him in the gearing system of gear wheels, bucket trucks with seats for passengers, mounted on the radial rods, freely suspended on the axles installed on poles associated with the body of the boat, the possibility is using the cyclic fluctuations in the bassinet at an angle of ±α when rolling keel boat waves surrounding water.

The design of our boats and versions of devices to ensure its progress shown on the drawings.

Figure 1 shows lifeboat 1, comprising a housing 2 with the installed screw 3, a shaft 4 which is connected through a system of gears 5 with a weight of 6, with seats 7 passengers, which is fixed on the radial rods 8, freely suspended on the axles 9, installed on the supports 10, rigidly connected with the hull of the boat, with the possibility of cyclical fluctuations bassinet at an angle of ±α, when the keel rolling of the boat in the storm waves surrounding water. To limit the sector rocking cradles, including the overturning of the boat on the cradle, or supports 10, or building boats set spring, pneumatic or other types of elastic dampers 11, with the possibility of contact with adequate supporting ledges on the supports and the cradle. An additional positive factor is higher center of gravity over metacentrum boats, which leads to its rapid turnaround in its original position (passengers must wear seat belts). To exclude arbitrary rotation of the cradles at the time of embarkation-disembarkation of passengers, the bassinet is enshrined in the boat hard detachable rods, or flexible belts 12, or slings, or stops, with the possibility of their subsequent separation pass the fats. For ease of boarding / alighting passengers boarding hatches 13 are located on both sides of the boat opposite the rows of seats and is equipped with locking systems 14, open and close from inside and outside the boat.

Secure the cradle straps 12 belt type 15 have the support 16 with covered belt clamping platform on an axis 17 which has an L-shaped swing handle 18 with teeth on its short side to hold the belt, between which and the presser pad introduced a free end, conceded in its upper part through the eyelet 19, is fixed, for example, on the ceiling of the cabin, and through the eyelet 20, mounted on the cradle. Thus the handles are located in the area available for passengers, and their turn-down is facilitated by application to it of the weight of the passenger. Such clamping is possible for the terminals in contact with ears hooks. The lines can be cut. Other versions of straps and clamps (such as type safety belts for passenger aircraft) and their mounts.

The most simple type of mounting cradles - a bunch of their brackets or straps in pairs with each other.

In addition to the seats 20, the lifeboat space for steering 21 and two removable assistants 22, which may be members of the ship's crew.

When installing in the case of two or more quantities of the cradles, each of them is connected through its system of gear with its shaft lead screw, for which they are displaced to the sides to her sides.

Other control systems and equipment boats similar base.

Figure 2 shows the kinematic diagram of the drive of the boat, which consists of the cradles 6, suspended on the radial rods 8 axles 9, installed on the supports 10. At the ends of the bassinet fixed wheel gear sectors 23 and 24, the axis 25 which are aligned with the common axis of the axle shafts 9, and with them entered into the engagement of the intermediate gear wheels 26 and 27 mounted on shafts 28 and 29 with the possibility of rotation in bearings placed in the slots 30, 31, secured to, or made in the supports of the cradle, and on both ends of these shafts is fixed mirror symmetric pair hrapovic wheels 39. On the one hand thereto adjacent intermediate gears 26 and 27, the ends of which has a pawl 40 with the possibility of rotation on the axis 41, and due to the clamping springs 42, dogs may be entered in engagement with the teeth hrapovic wheels 39, ensuring the engagement of the wheels 26 or 27 with the shaft. To the ratchet wheel 39, a mirror mounted on the other side of the shafts 27, 28, adjacent the conical wheels 32 and 33, the ends of which also have dogs 40 with the possibility of rotation on the axis 41, and due to their pressure springs 42, they can be entered in azepine with the teeth of their hrapovic wheels. Between the conical wheels, normal to their common axis parallel to the axis of the shaft 4 screw, put them in the General engagement of bevel gear 34, and the shaft 35 mounted output gear wheel 36, which is inserted into engagement with the gear 37 of the shaft 4 lead screw. Instead of the output gear wheel 36 can be mounted gearbox, or between the output wheel 36 and the gear 37 can be set to a block or blocks of the dual gears that increase the speed of rotation of the shaft lead screw.

To increase the rigidity of the system of swing, especially with side rolling of the boat, between the ends of the cradle 6 and the supports 10 entered the balls or rollers 38, e.g., conical, vertices which are aligned with the center of swing of the cot, or on its outer radius at the ends or in the middle part, at least one rim entered in the corresponding groove, mounted on poles bassinet or on the hull of the boat, and in it all these supports are fixed integrally.

The principle of operation of the kinematics of the drive boat next. When the keel rolling of the boat, its bow and stern alternately bend at an angle of ±α due to the motion of the waves, and the cradle 6, suspended on the radial rods 8, loosely mounted on the axle shafts 9, mounted on poles 10, under the action of gravity forces retain the vertical position toward the center of the Earth that provides the rotation of lol is to angle ±α when moving clockwise and counterclockwise relative to the original horizontal position of the boat. When you rotate the latter clockwise, fixed at its ends leading toothed sectors 23 and 24, the axis 25 which are aligned with the common axis of the axle shafts 9, make the same turn, and entered with them into engagement of the intermediate gear wheels 26 and 27 make a counterclockwise rotation on the shafts 28 and 29 mounted for rotation in the slots 30 and 31. At both ends of these shafts mirror-symmetrically fixed pair hrapovic wheels 39, which are attached to the ends of the gear wheels 26, 27, 32, 33, mounted with dogs 40, with the possibility of rotation on axes 41 and the pressing spring 42 to the teeth of the ratchet wheel 39. The gear 26 is engaged with the first ratchet wheel and results in counterclockwise rotation of the shaft 28, which rotates counterclockwise set mirrored the first, the second ratchet wheel (when looking at it from the side of the shaft 28 is rotating clockwise), and when the contact of teeth with dogs 40 mounted on the end of the conical gears 32 with the possibility of rotation on axes 41, due to the pressure of their springs 42 to the teeth of the second ratchet wheel, the shaft rotates counterclockwise is conical wheel, which rotates counterclockwise (when the view from the side of its shaft 35) bevel gear 34, and it simultaneously rotates counterclockwise p is the CTL installed on its shaft 35, the output gear wheel 36, and through it clockwise gear 37 of the shaft 4 of the screw 3, and it rotates clockwise entered with her engages a second bevel wheel 33, mounted with its end face dogs 40, with the possibility of rotation on axes 41 and presses the springs 42 to the teeth of the third ratchet wheel 39 mounted in the same direction as the first ratchet wheel intermediate gear wheel 26, so dogs slide on the third ratchet wheel and does not rotate the shaft 29 mounted on the other end of the fourth ratchet wheel 39, mirror-symmetrical to the third and the first ratchet wheel. At the same rotation of the cradle is pivoted clockwise toothed sector 24 rotates counterclockwise intermediate gear wheel 27 (when looking at it from the side of the shaft 29, it rotates clockwise), and installed on his end of the pawl 40 with the possibility of free rotation on the axis 41 and is pressed by a spring 42 to the teeth of the fourth ratchet wheel, not included into engagement with these teeth and also can't rotate the shaft 29.

During the reverse rotation of the cradle (counterclockwise) the process is reversed: the leading toothed sectors 23 and 24 rotate the intermediate gear wheels 26 and 27 in a clockwise direction, while the ratchet toothed wheel 26 is opened, and the wheels 27 is closed which it rotates clockwise shaft 29, which closes the ratchet toothed bevel wheel 33, and it also rotates clockwise, resulting in the counter-clockwise rotation of bevel gear 34. Thus, the associated output gear wheel 36 is identical with the first swing of the cradle the direction of rotation is counterclockwise, which provides constant direction to the clockwise rotation of the propeller at all stages of the swing of the cradle.

Braking bassinet at the endpoints of its swing can be smoothed by inertial rotation of the shafts 28 and 29 of the gear wheels 32, 33, except that the output gear wheel 36 may be in the form of a flywheel, which continues its inertial rotation when the fall speed of rotation of the shaft 35, by means of their connection through the ratchet wheel with the spring-loaded dogs, by analogy with rapovymi mechanisms connections gears 27 and 33, or other mechanisms and couplings, gearing which is possible with the advance of the angular velocity of rotation of the flywheel angular velocity of the rotating shaft.

Instead of the bevel gear wheel 32, 33, 34 can be applied overrunning differentials with bevel or hypoid, or with a spiroid gearing, input shafts or gears which are connected with the shafts 28 and 29, and the output shaft is connected with the shaft 4 screw directly or through to anicello gear. Can also be used engagement with the helical gear wheel connected to opposite sides of the shafts 28, 29 through its ratchet wheel mounted on the ends of the helical wheel spring-loaded dogs, or other types of gearing for rotating one of these shafts in direct, and the other in a reverse rocking of the cradle, and put into the engaged position, perpendicular to the helical wheel, helical toothed gear mounted on the shaft coaxially with the output gear wheel 36, or associated with gear, put into mesh with the gear 37 of the shaft 4 lead screw.

To increase the frequency of rotation of the shaft 4 lead screw through a system of gears bassinet radius is fixed at its terminals sectors leading gear wheels 23, 24 can be reduced, and between them and the intermediate toothed wheels 26 and 27 is introduced into the engagement blocks or block dual gear wheels mounted on the support 10 bassinet or on the hull of the boat.

Figure 3 shows the new implementation of the mechanism of rotation of the shaft of the screw, which instead hrapovic wheels with dogs, on the shafts 28, 29 and the intermediate gear wheels 26, 27, can be installed overrunning clutch, for example, in version 1 with the teeth on the coupling sleeve 43 connected with the gear wheels, and smooth (no teeth) by the coupling 44, associated with the shaft, between the teeth of the coupling RA is medeni balls or rollers 45, ensure that it engages with the coupling shaft for direct rotation of the gears 26, 27 (in this case, when rotating them counter-clockwise, when looking from the shaft side). For bevel gears 32 and 33 can be installed overrunning clutch in version 2, for example with a smooth coupling sleeve 46 associated with the gears, and the teeth on the coupling sleeve 47, associated with the shaft, and between the teeth posted by balls or rollers 45, ensuring the engagement of the coupling with the shaft for direct rotation (in this case, while rotating it counterclockwise, when viewed from the shaft side).

To reduce the size of the connection, smooth coupling 44 and 46 in versions 3 and 4 can be eliminated, and in versions 5 and 6 instead of the toothed coupling sleeve, the teeth can be performed in the Central holes of the wheels 26 and 27, or on the ends of the shafts 28 and 29, entered into a smooth hole of the conical gears 32 and 33. Such compounds can be made for the shaft 35 and the output gear 36. All other elements of the gears and how they work appropriate to their previous performances.

Instead of the proposed compounds may also use mechanical Cam clutches with rapovymi teeth, with orientation-dependent rotation.

Figure 4 shows the new version of the kinematics of the drive shaft of the lead screw, in which the two most cradles, through the output gear 36 and gear 37, rotate the common shaft 48, reducing the number of propellers, which facilitates and simplifies the design of the boat and its management. To compensate for differences in speed of rotation of the toothed wheels 36, they must have a detachable connection with the shaft 35 through the application shown in figure 2 and 3 hrapovic wheels, overrunning and Cam clutches, however, will be the loss of power.

Figure 5 shows the new execution boats, which provide electricity for their own needs, for which the output gear wheel or shaft lead screw through a gear 49, or through other transfer, introduced in engagement with the electrical generator 50, charging batteries or capacitors, electric current (for condensers possible execution of the electronic synchronization system of a given frequency discharge).

For the needs of the boat and its progress in the calm outside cuttings can be set rotating solar battery 51, with the possibility of hermetic closure for the period of the storm. In addition, to ensure the progress of the boat in calm perhaps swinging cradles sitting in their passengers.

Figure 6 shows the new version of the boat 1, comprising a housing 2 with the installed screw 3, a shaft 4 which is connected through a new system of gear wheels 52 mounted on radial is cerinah 8, freely suspended on the axles 9, installed on the rigidly connected with the hull of the boat supports 10, with the possibility of cyclical fluctuations on the angle ±α when the keel rolling of the boat in the storm waves surrounding water, the cradle 53, which, to exclude negative contacts sitting opposite each other passengers, seats 7 installed in one row. However, this decreases the number of seats for passengers and decreases develop when the swing cradles power, to compensate for which you want to increase the size of the boat. Therefore, in addition to accommodation in cradle seats in two rows facing each other or in a row behind each other, the possible execution cradles with more than two rows, with different combinations of options for boarding passengers to each other.

To exclude arbitrary rotation of the cradles for boarding and alighting passengers, cradles fixed in the housing of the boat hard detachable rods, or flexible belts 12, or slings, or stops, or bassinet in pairs interconnected by brackets or straps, with quick their subsequent separation passengers.

To increase the rigidity of the cradle with side rolling of the boat between the supports 10 is installed crossbars 54, and between them and the ends of the bassinet entered the balls or rollers, e.g., conical, vertex which combined the center of swing of the cradle, or on the outer radius at the ends or in the middle of the cradle, at least one rim entered in the corresponding groove, mounted on poles bassinet or on the hull of the boat, and in it all these supports are fixed integrally.

Restriction sector rocking cradles, including overturning boats, provide a spring, pneumatic or other types of elastic dampers 55 mounted on the rods 8 bassinet, or on the supports 56, or on the hull of the boat with the possibility of contact with appropriate support extensions.

Transmission of rotation of the running screws 3 through the elongated shafts 57, 58, and for the convenience of placing system of gear wheels connecting the lead screw with carrycot, between fixed on the rods bassinet sectors 23, 24 leading gears and intermediate gears 26 entered engages parasitic gears 59, 60, or chain, or belt, or other similar transmission installed on the supports of the cradle or on the hull of the boat.

The principle of operation of the kinematic system of the new version of boat similar to the one described above.

To improve the efficiency of the lead screw at different speeds and amplitudes rocking bassinet is made adjustable in step of previously known devices for all proposed versions of the boats.

To eliminate timing mechanisms re the Seminary system of gear wheels in different directions rocking bassinet lead screw variable pitch can be made with the possibility of reverse when reverse motion of the bassinet which further simplifies the system gears up to unilateral, although this option leads to undesirable load asymmetry and deformities of the bassinet.

The combination of all these signs is shown in figure 1...6 performances boats with devices to ensure their progress and their installation allows to characterize them as technical solutions that are new and non-obvious from the underlying technology. Their manufacturing is possible in real industrial production, as the design of boats and gears similar to a known and bassinet similar garden or children's swings, adapted to the new conditions. All performance boats, structures cradles and systems gears are a development of the previous versions, consequential from each other, which ensures the unity of purpose of the proposed application for the invention. Thus, it is possible to classify all proposed in the application of technical solutions, as inventions that meet all the required criteria.

All of the proposed execution of the cradles, systems of gears and their installation in the boat, when the oscillation waves that allow stable rotation driving screws with high power and with a constant direction of rotation, therefore, eliminates the need for other power transmission device is two and engines, which increases the overall efficiency of the system, consisting of only 5 pairs of gear wheels, 7 concurrent bearings and 3 couplings, up to 85% and provides a positive effect from their use.

Real options offer boats is possible at any base sizes of boats and buildings, which facilitates their selection, design and manufacture. Differences exist only in the kinematics of the drive shaft of the propeller and the mechanisms controlling its pitch, which is derived from the actual speed of the shaft of the propeller, depending on the actual amplitude and the number of oscillations of the boat waves. Usually the waves in a storm provide value from 6 to 10 cycles of oscillations per minute, while limiting the maximum sector fluctuations carrycot angle α_max=±45° (storm more than 7 points), and the minimum - angle α_min=±15° (storm 3 points), which provides an effective range of speeds and capacities of the boat.

For example, for the original versions of the boat and its kinematics, shown in figures 1 and 2, with two cradles with a weight of 150 kg, 8 passengers each, with an average mass of 75 kg, the total mass m will be the value of

m=2(150+8×75)=1500 (kg) or 1.5 T.

When the radius of the bassinet r=1.3 m, the height of the center of mass of the h_m=0.5 m from the floor of the bassinet and the angles of oscillation α_max=±45°, α_min=±15°, the energy potential of E raised the Oia its center of mass to the height h will be

E_max=mgh_max=mg(r-h_m)(1-cosα_max)=1,5×9,8×(1,3-0,5)×-(1-cos45°)≈3,4 (kJ),

E_min=mgh_min=mg(r-h_m)(1-cosα_min)=1,5×9,8×(1,3-0,5)×(1-cos15°)≈0,4 (kJ).

When two such liftings for the cycle of movement of the waves and at 6 cycles per minute, developing in an hour (60 min) power N, the total system efficiency η=0,85, will be the amount

N_max=η×2×6×60×E_max=0,85×2×6×60×3,4≈2170 (kW)

N_max=η×2×6×60×E_max=0,85×2×6×60×0,4≈255 (kW).

Because the available lifeboats engine power, as a rule, does not exceed 50 kW, the obtained data confirm the feasibility of the proposed option.

When the outer diameter of the bassinet 2r=2×1,3=2.6 m dividing the diameter of a sector of a leading gear wheel will be the same size of 2600 mm, when dividing the diameter of the intermediate gear wheels 200 mm (acceptable for installation in him overrunning), their ratio will be the value of

n₁=2600:200=13.

At the same dividing the diameter of the associated conical wheels and dividing the diameter mating with them bevel gear 80 mm, gear ratio between them will be the value of

n₂=200:80=2,5.

When dividing the diameter coaxially associated with the conical gear of the output gear 360 mm and the diameter mating with him pinion shaft lead screw 80 mm, predation the E. the relationship between them will be the value of

n₃=360:80=4,5.

Then the total gear ratio of n₀system gear mechanism swing bassinet amount value

n₀=n₁n₂n₃=13×2,5×4,5=146,25.

In this case, the number of revolutions of the lead screw n_Bfor one cycle of a wave-motion amount value

n_Bmax=(2×2×α_max):360°n₀=(2×2×45°):360°×146,25≈73 (about),

n_Bmin=(2×2×α_min):360°n₀=(2×2×15°):360°×146,25≈24 (about).

With 6 cycles of movements of waves per minute, these values will be

∑n_Bmax=6n_Bmax=6×73=438=(rpm),

∑n_Bmin=6n_Bmin=6×24=146=(rpm),

This range is acceptable for the effective operation of the controllable pitch propeller, but there are other possible gear ratio and speed.

These data are the basis for the manufacture of boats, then the calculation is an engineering task that are available for professionals with an average level of engineering training.

An additional advantage of this lifeboat is almost unlimited range of its stroke, and in such capacities and speeds can be effective movement of the boat to the shore, towards and after passing vessels, which dramatically increases the chances of rescue passengers.

In addition, in comparison with the existing rescue boats, no fumes in the cabin of fuel, exhaust gas and noise work the surrounding ice, and less sickness passengers waves, contributes to better their physical and moral condition, which increases the chances of their salvation.

The achievement of technical and economic indicators for such technical solution is not necessary, as it ensures the salvation of human lives that has a social effect, but the possible economic effect can be estimated through the amount of insurance in case of death of passengers and Klenow crew. However, there is a direct economic effect, because the cost of production, we offer boats can be below the cost of production of existing boats, equipped with internal combustion engines and fuel, have their value, or boats with other power plants, but its value depends on the specific conditions, therefore, can be estimated conditionally in 10...20 thousand$ per boat.

The above data confirms the feasibility of wide application of the proposed boats, devices to ensure their progress, their positioning and application.

Currently being prepared for production, we offer lifeboats on JSC Kherson shipyard, Ukraine.
