Description

A sailing system with the ability to generate electricity

[0001] The invention relates to the field of shipbuilding, namely to the designs of wind propellers for watercraft of various types, equipped with a sail-wing system in various designs, made with the possibility of generating electrical energy by converting the kinetic energy of the wind flow into mechanical energy of rotation, followed by its conversion into electrical energy.

[0002] A sail power plant known from the prior art is known [CN111268080, B63H9 / 06; B63H9 / 08; F03D5 / 00; published 12.06.2020], having the functions of a navigational aid and electricity generation. The dual-purpose sail comprises a pair of arc-shaped sail hulls mounted on a mast; the sail additionally comprises a support, the support comprises a lower edge and two support levers, the distance between the two support levers is greater than the width of the arc-shaped sail hull... This sail system is proposed for use in generating energy when a vessel is moving against the wind, which will present additional resistance to the vessel's motion and, accordingly, will require additional energy costs to overcome the resulting resistance to the vessel's motion, this circumstance levels out the generation of electricity in this way.These sails are essentially classic square sails, which can only be used effectively as a propulsion device when the vessel is underway, reducing the overall efficiency of the sailing vessel. For these reasons, this design is unsuitable for use as a vessel's primary propulsion device.

[0003] A wind power plant similar to the claimed one in terms of the totality of its essential features is: a vessel for generating electricity with a vertical wind generator [KR20220060503, B63B35 / 00; B63H9 / 061; B63H9 / 067; B63J3 / 04; F03D3 / 00; F03D3 / 06; F03D9 / 32; published 11.05.2022]. [WO2023054821, B63H9 / 067; F03D3 / 00; F03D3 / 06; F03D9 / 32; published 06.04.2023]. The present invention relates to a vessel for generating electricity, equipped with a wind turbine that generates energy using a rotating blade assembly with the possibility of sailing, and, more particularly, to a vessel for generating electricity, capable of generating energy using a rotating blade assembly installed on the vessel and, if necessary, can serve as a sail.A disadvantage of vertical turbines is their low efficiency in areas with constant winds, such as seas and coastal areas. This is due to the high drag force exerted by the wind when attempting to capture the moving airflow. Another drawback is the increased load on the blades, as they are constantly subjected to centrifugal force and variable pressure from the oncoming airflow. Compared to horizontal units, this vertical turbine has a lower efficiency. Under the sail, which this unit is transformed into, only full-course sailing is possible, as on a sharp course, much of the sail-generator structure will negatively impact the airflow around the working portion of the sails, leading to a critical drop in lift, making it difficult to maintain the desired course.

[0004] The closest design to the claimed invention is the sail system [RU2827744, B63H 9 / 00, published 05 / 24 / 2024 - prototype]. The sail system includes a mast and rigid sails and is characterized by the mast being equipped with a device for 360-degree rotation.in a horizontal plane of at least two beams, with each beam structurally connected to at least one axle box, to one plane of which a motor is connected for rotating the shaft, and on the other side of it a shaft is mounted on bearings with the possibility of rotation, on which at least one support is fixed, made with the possibility of translational movement along the shaft, as well as up and down relative to the axis of the shaft, having structural elements for hanging on it at least one rigid wing sail, having an asymmetrical transverse profile, and the wing sail consists of one support section or several sections, one of which is a support, wherein the sail system is made with the possibility of transition from the first operating state, in which the shafts are located between the mast and the bow of the vessel symmetrically relative to the centerline plane of the vessel at an angle of 130 degrees to 180 degrees.In the second operating mode, in which the shafts are parallel to each other, facing the wind at a given angle of attack, the wing-sails' leading edges are brought into contact with each other, forming a single straight sail, and the convex surfaces of the wing-sails face the bow of the vessel. This invention improves the vessel's performance and seaworthiness, reduces its roll, and simplifies the sail control system on all courses relative to the wind. A disadvantage of the sailing system described above is that it is intended for use only as a propulsion device and does not provide the ability to generate electricity. Technical challenge

[0005] The objective of the present invention is to create a sailing system that has higher performance qualities and sail efficiency compared to the prototype.

[0006] The technical result is to ensure the possibility of generating electrical energy during the operation of the sailing system while maintaining the possibility of its operation as a propulsion device. Solution to the problem

[0007] The said problem is solved and the technical result is achieved by the fact that a sailing system with the possibility of generating electric power is proposed, including a mast and sails, wherein the mast is provided with a device for rotating at least two beams by 360 degrees in a horizontal plane, and with each beam at least one axle box is structurally connected, to one plane of which a motor for rotating a horizontal shaft is connected, and on the other side of it a horizontal shaft is mounted on bearings with the possibility of rotation, on which at least one support is fixed, made with the possibility of translational movement along the horizontal shaft, as well as up and down relative to the axis of the horizontal shaft, and having structural elements for hanging on it at least one wing sail, characterized in that the sail consists of at least two segments, wherein each segment consists of one support section or several sections,one of which is a support one, wherein the sail system additionally contains at least one battery, as well as a generator connected to a horizontal shaft configured to rotate the generator, wherein the sail system is configured to reversibly transition from the propulsion mode, in which the sail segments are fixed in such a position that the lifting forces generated on the sail segments have the same direction toward the bow of the vessel, ensuring its movement on a given course, to the mode of generating and accumulating electrical energy by installing shafts holding the sails parallel to the direction of the wind, wherein the sails with their leading edges are set in the direction of the wind, followed by a change in the spatial position of at least one sail segment with its fixation in a position in which the lifting forces generated on the sail segments create a torque on the shaft that rotates the generator.

[0013] There is a variant in which more than one support is installed on the shaft.

[0014] There is an option in which two axle boxes with installed shafts are structurally connected to each beam. The essence of the invention

[0015] The sailing system includes a mast 1, provided with a device 2 for rotating through 360 degrees in a horizontal plane, structurally connected to it by fixing the root ends of two beams 3 in it, wherein an axle box 4 is structurally connected to each beam 3. A generator 5 and an engine 6 are connected to one plane of the axle box 4, and on the other side a horizontal shaft 7,,,,,,, is mounted in the axle box 4 on bearings with the possibility of rotation. The horizontal shaft 7 has parallel working surfaces 8, on which a support 10,,,,,,, is fixed by means of sliding faces 9 with the possibility, by means of a device 11, of moving progressively along the horizontal shaft 7, as well as up and down in the vertical direction relative to the axis of the horizontal shaft 7. The support 10 may have a centering device 12, relative to the horizontal shaft 7.The support 10 has structural elements, in particular, it may have heads; an upper 13 and a lower 14,,,,, on which the slats-flutes 15,,,,, for hanging the wing sail on them are secured. The wing sail consists of an upper 16 and a lower 17,,,, segment. Segments 16, 17 of the wing sail may consist of a single section, which is a supporting 18, or several sections: a supporting 18, intermediate 19 and an end 20,,,,. There may be more than one intermediate section. In a particular embodiment of the invention, the sail-wing is made rigid and has an asymmetrical convex-concave profile, which has a convex surface 21, a concave surface 22, a trailing edge 23 and a leading edge 24. In a particular embodiment of the invention, the axle box 4 is connected to the beam 3 by installing the axle box 4 in the rotating part 25 of the slider 26, with a sliding element 27 for placing the beam 3 in it.In a particular embodiment of the invention, two axle boxes 4 with horizontal shafts 7 installed therein are connected to a beam 3 by installing the axle boxes 4 in a rotating part 25 of a slider 26. In a particular embodiment of the invention, when installing an additional segment 28 on a support 9, a head 29 holding it is mounted on the side surface of the support. Heads 13, 14 can have mechanisms for moving 30, rails-feet 15. Heads can have devices 31 for rotating around the vertical axis of the support 10. In a support carrying one wing sail, the upper 13 and lower 14 heads can have a device 32 for rotating the rail-feet 15 around its horizontal axis. A rotating device 33,,,,, of the support section is fixed on the rail-feet 15. In a particular embodiment, the wing sails are made soft and can be gaff sails mounted on a rigid frame 34.

[0016] Mast 1 is a link in the sail system, structurally connecting all elements and blocks of the sail system to the vessel's hull to transmit wind energy, propelling the vessel along a given course. Rotating device 2 is secured to mast 1 and is used to connect mast 1 to beams 3 of the sail system. Rotating device 2 allows beams 3 to rotate horizontally around the vertical axis of the mast by 360 degrees, adjusting the position of the wing sails based on wind direction and the vessel's course. Beam 3 is structurally connected to axlebox 4. Generator 5 and engine 6 are attached to one plane of the axlebox, while horizontal shaft 7 is mounted on bearings on the other side of the axlebox, allowing rotation. Axlebox 4 may be installed directly on the end of beam 3 or secured to rotating element 25 of slider 26.Generator 5 is structurally connected via axlebox 4 to rotating shaft 7 and is intended to generate electrical energy for the sail system when operating in generation mode. Motor 6 is designed to rotate shaft 7, implementing the reversibility of the wing sail held by the shaft. Runner 26 is a unit of the sail system that can move translationally along beam 3 and also rotate axlebox 4 and, consequently, shaft 7 in the horizontal plane at the required angle. Runner 26 consists of two elements: slide 27, allowing translational movement along beam 3, and rotating part 25 with axlebox 4 installed therein; there may be two axleboxes 4 installed. Horizontal shaft 7 is designed to secure support 10 to it, on which the wing sails are suspended. When the system operates in the propulsion mode, the horizontal shaft 7 transmits the lifting force from the wing sail through the beam 3 and the mast 1 to the hull of the vessel, for its movement along a given course.When operating in the generation mode, the shaft 7 transmits the torque generated by the wing-sail to the generator 5 connected to it, for generating electric power. In particular, the horizontal shaft 7 can be made cylindrical with double-sided parallel chamfers, which form working surfaces 8. The horizontal shaft 7 can also have a different cross-sectional profile with the formed working surfaces 8. The working surfaces 8 of the horizontal shaft 7 are used to hold the carriage 10 in the required spatial position. In addition, the working surfaces 8 are tightly coupled with the sliding faces 9 of the carriage 10 and cause the dependent joint rotation of the shaft 7 with the carriage 10. In the initial operating position of the horizontal shaft 7, the planes of the working surfaces 8 are installed vertically. The carriage 10 is an element of the sail system, connecting the wing-sail to the shaft 7, and performs the basic adjustments and settings of the sail for the standard functioning of the sail system.The support 10 may be designed as a hollow parallelepiped. The support 10 is connected to the shaft 7 such that the largest opposite faces 9 of the support 10 tightly embrace the working surfaces 8 of the shaft 7, allowing the support 10 to move translationally along the horizontal shaft 7, as well as up and down, relative to the axis of the shaft 7. This connection ensures dependent joint rotation of the horizontal shaft 7 with the support 10 about the axis of the horizontal shaft 7, which allows the support 10 and, accordingly, the wing sail to rotate 180 degrees around the axis of the shaft, achieving sail reversibility. The support 10 may have a centering device 12 with the horizontal shaft 7, used when rotating the wing sails around the axis of the shaft 7, when changing the vessel's course, and in generation mode.It should be noted that, in general, the sail system will operate normally even without the centering device 12 on the support, since in generation mode, the support's torque is created by a couple of forces and is a free vector, independent of the point of application. Support 10 has a device 11 for longitudinal movement along horizontal shaft 7. Support 10 allows the wing sail's deviation angle (ϕ) to be adjusted from the vertical to reduce the vessel's roll. On support 10, in its upper and lower parts, symmetrically relative to the central horizontal plane of support 10, heads (upper 13 and lower 14) can be mounted for rotation around the vertical axis, respectively, with slats-flutes 15 attached to them in a specific manner, on which the wing sails are hung. More than one wing sail can be hung on support 10, if necessary.When installing an additional sail segment 28 on the support 10, the head 29 holding it is mounted on the side surface of the support 10. The heads of the support 13, 14 serve to install the wing sail segments in them by means of the slats-feet 15. For the sake of clarity, in relation to the horizontal shaft 7, the heads can be conventionally designated as the upper head 13 and the lower head 14, respectively. The designation convention arises from the ability of the support 10 to rotate around the axis of the shaft 7. The heads 13, 14 can have mechanisms 30 for moving the slats-feet 15. The heads can also have devices 31 for rotating around the vertical axis. By means of devices 31, for the efficient operation of the system, the angles of attack a of the sail segments are set, and in the generation mode, the angles of attack a of the sail-wing segments, respectively the upper 16 and lower 17, are set equal in magnitude, but in different directions to the direction of the speed vector of the oncoming wind,,,.It should be noted that when the sail system is equipped with rigid wing sails with an asymmetrical transverse profile, in particular a convex-concave profile, the sail system can be operated in generation mode without setting different angles of attack on the wing sail segments using the heads, as in this case, lift is generated on the sail segments at an angle of attack of up to minus 5 degrees. When the sail system is equipped with soft sails, for normal and efficient operation in generation mode, the heads can be used to set different angles of attack on the segments. The sail system rigging options shown in this description utilize wing sails with a convex-concave profile, which has a higher lift coefficient. Setting the angle of attack for such profiles increases the efficiency of wind force utilization in various operating conditions.In the support 10, which carries one wing-sail, the upper 13 and lower 14 heads have a device 32 for rotating the rake-flute 15 around its horizontal axis. The main difference between the supports 10, which carry a different number of wing-sails, lies in the design of the heads 13, 14. The rake-flute 15 is a structural element of the sail system, secured to the heads 13, 14 of the support 10, which serves to move and maintain in a given position with the ability to rotate around the horizontal axis the supporting section 18 of the wing-sail. A rotating device 33 of the supporting section 18 is secured to the rake-flute 15. The sail is the propulsion device of the vessel. Rigid sails of watercraft are made like airplane wings and generate lift using the principles of aerodynamics characteristic of aircraft wings, which is why they are called wing-sails.Such sails are typically mounted vertically on vessels and may have a symmetrical or asymmetrical transverse profile, in particular, a convex-concave profile. A wingsail may also be soft, in particular, in the form of a classic oblique sail mounted on a rigid frame 34. On a wingsail with an asymmetrical convex-concave transverse profile, the direction of the lift vector Fy generated by the wing, without significant error, can be assumed to extend outward from the convex surface of the wing and perpendicular to it. Sail reversibility is the change in direction of the lift vector generated by the wingsail (or wingsail segment) to the opposite of the given direction. The reversibility of a wing-sail with an asymmetrical convex-concave transverse profile is achieved by rotating it around a horizontal axis by 180 degrees, whereby the direction of the lift force created on the convex plane of the wing-sail changes to the opposite.The working position of the wing sail in the propeller mode, having an asymmetrical convex-concave transverse profile, is generally determined when the wing sail is positioned vertically and faces the convex surface 21 that forms it towards the bow of the vessel, which ensures adequate thrust in the direction of the vessel's movement.

[0017] The claimed sailing system has two main operating modes: the propulsion mode, when the vessel follows a given course using the sails as the main propulsion device, and the generation mode, when the sails are reconfigured in a certain way to generate electrical energy.

[0018] In propulsion mode, the lift generated by all sail segments is directed in one direction, conventionally toward the vessel's bow, and provides the propulsive force for the vessel's movement in a given direction. The sail system in propulsion mode has two main operating states. When the vessel is sailing at full speed, the sail system operates similarly to "classic" square sails. With the vessel at full speed, beams 3, rotating around the vertical axis of mast 1, position horizontal shafts 7, which hold the wing sails, between mast 1 and the vessel's bow, positioning them symmetrically relative to the vessel's centerline, at an angle of 130 degrees to 180 degrees to each other. The wing sails are also positioned symmetrically relative to the vessel's centerline, with the leading edges of the wing sails butting against each other, forming a single square sail, and the convex surfaces of the wing sails facing the vessel's bow.In this way, a single sail surface is created from individual sail-wings, as shown, allowing the most efficient use of wind energy to move the vessel along the chosen course.

[0019] When sailing a sharp course upwind, this sailing system enables tacking. When sailing upwind, the sailing system is configured as follows: beams 3, rotating around the vertical axis of mast 1, are adjusted so that shafts 7 are aligned with the wind, parallel to each other, at a predetermined angle of attack relative to the wind direction. The leading edges of the wing sails also point downwind, and the convex surfaces of the wing sails face the bow of the vessel, ensuring adequate propulsion in the direction of the vessel's travel.

[0020] In generation mode, the sail system transforms the conventionally linear sail-wing into a three-dimensional structure: as a result of this transformation, the multidirectional lift forces of the sail-wing segments relative to the horizontal shaft 7 create a torque on the shaft 7 supporting the sail, which is used to rotate the generator 5 and generate electricity. Thus, the sail system is transformed from a propulsion system into a wind generator.

[0021] The device operates as follows. The principle of the reversible transition of the sail system to the generation mode is shown using a sail system variant where a single wing sail is mounted on a support 10, divided into two segments 16, 17, which consist of a single supporting section 18. At the beginning of the transition to the generation mode, the sail system is adjusted by rotating the beams 3 to the desired angle so that the horizontal shafts 7 of the system are aligned parallel to the wind flow direction, and the leading edges 24 of the wing sails are directed into the wind. The supports 10 of the wing sails are centered relative to the horizontal shaft 7 by means of a device 12. Since the wing sail segments, the upper 16 and the lower 17, are identical and oriented identically downwind, the lift forces Yв and Yн arising on the convex surface of the segments are equal in magnitude and direction.The direction of the lift vector of the upper segment 16 coincides with the direction of the lift vector of the lower segment 17 and, as a result, there is no torque on the shaft 7, and the resultant force Y'p is the thrust force. Then, the rotation device 33 rotates the support section 18 of the upper segment 16 by 180 degrees around the horizontal axis. As a result of this rearrangement, the support section 18 of the upper segment 16 is installed and fixed symmetrically with the support section 18 of the lower segment 17 with respect to the horizontal shaft 7. In this case, the support section 18 of the upper segment 16 performs reversibility, changing the direction of the lift vector by 180 degrees. Further, the upper head 13 and the lower head 14 of the support 10, rotating around the vertical axis of the support 10 at the same angle, but in opposite directions, set the required angles of attack a and a' of the sail segments, and thereby transferring the sail system to the working state of the generation mode.The oncoming air flow generates parallel, equal-magnitude lift forces on the support section 18 of the upper segment 16 and the support section 18 of the lower segment 17, directed in opposite directions from the axis of rotation of the horizontal shaft 7. These forces create a torque on the shaft 7, which drives the generator 5. This system of forces is called a force couple. The action of this force couple on the horizontal shaft 7 underlies the operating principle in generation mode for all the described sail system variants. This generates electrical energy, which charges the batteries that power the propulsion motor and other electrical equipment on the vessel.

[0022] This is the primary property of a sail system—changing the direction of the lift vector of structurally unchanged sails to achieve a new technical result when using the sail system. With the sail system design shown in pos. 7a–7d, the system's conversion from propulsion to generation mode occurs similarly to that described above; the only difference between the two designs is the position of rack-flute 15.

[0032] pos. 10a - 10g shows a diagram of a sail made of two segments during the transition from the propeller mode to the generation mode.

[0033] Transition to generation mode for a sail system with telescopic sails is performed similarly to that described above, with the difference being that, before rotating upper segment 16 to the opposite side of shaft 7, sections 19 and 20 are folded into support section 18. Support section 18 is then rotated to the opposite side of shaft 7, reversing the wing-sail. Following this, telescopic sections 19 and 20 extend from the opposite side of support section 18. Next, the heads set the angle of attack α of the upper segment and the angle of attack α of the lower segment, switching the system to generation mode.

[0034] The transition to system generation mode with support 10, on which two wing sails are mounted, is shown in . Setting the sails to the wind proceeds in the same manner as described above. Next, the upper segments are folded into support sections. Then, support sections 18 of the upper segments are rotated 180 degrees, making the upper sail reversible. Following this, sections 19 and 20 are extended from the back of section 18. Next, the upper 13 and lower 14 heads, rotating around the vertical axis, set the desired angle of attack a of the sails. Then, using rotation devices 33, the sail segments are rotated around the horizontal axes of sections 18 by an angle of 45 degrees. from the vertical plane of the support, forming a four-bladed rotor symmetrical relative to the horizontal shaft 7 with uniformly directed, clockwise or counterclockwise, vectors of lifting forces generated on the convex surfaces 21 of the sails, which causes the rotation of the shaft 7 to generate electricity by the generator 5.

[0035] Positions 9a–9g show a variant with a support on which a wing sail consisting of three segments is suspended. Rail-flute 15, which holds additional segment 28, is mounted on head 29. In the initial position, segment 28 is folded into support section 18, and the sail is in the propulsion position. After setting the system to the wind, as described above, sections 19, 20 of the upper and lower segments of the sail are folded into sections 18, then the slats-flutes 15 of the upper and lower segments are rotated in the device 32 in such a way that the angle between the three slats-flutes 15 in the plane perpendicular to the horizontal axis of the shaft 7 is 120 degrees, while the support section 18 of the upper segment, depending on the choice of the direction of rotation of the shaft 7, clockwise or counterclockwise, rotates by 180 degrees, making the upper segment of the sail reversible.Support section 18 of additional segment 28 rotates 90 degrees around its horizontal axis, thereby generating lift forces on segments 16, 17, and 28, the vectors of which are directed in the direction of rotation of the wind turbine. The heads of segments 16, 17, and 28 then rotate to set the angle of attack a. Sections 19 and 20 of segments 16, 17, and 28 are unfolded into their operating position. The oncoming wind generates lift on the sail segments, which creates a torque on shaft 7, which holds the wing sail, transmitted to generator 5. Thus, the wing sail is configured as a three-bladed wind turbine.

[0036] The system can operate in generation mode using soft sails made of modern materials. Figures 9d-9z show a version with a soft sail. The upper 16 and lower 17 sail segments are mirror-symmetrical relative to shaft 7 and act as oblique soft sails. When switching from propulsion mode to generation mode, the upper 13 and lower 14 support heads, rotating around the vertical axis by the same angle but in opposite directions, set the required angles of attack a, a' for the sail segments. As a result, the oncoming airflow creates lift forces on the upper and lower sail segments in opposite directions relative to horizontal shaft 7, thereby generating torque that drives generator 5.

[0037] Thus, the description demonstrates the solution to the technical problem. The result is a hybrid sailing system that serves both as a vessel's propulsion system and as a power generator, ensuring the independent operation of watercraft of various types and classes.
