Description

Technical Field

[0001] This invention relates to a lateral propulsion device for ships. Background Technology

[0002] As is well known, maneuvering a ship using the main propulsion system and rudder during berthing or unberthing is complex, especially for large ships.

[0003] In fact, using a rudder in confined spaces and at low speeds is neither easy nor effective, because a rudder (as an airfoil) requires flow in water at a given speed to generate lift. Furthermore, since the main propulsion system and rudder are located at the stern, the bow area of ​​the vessel is essentially uncontrolled during berthing and unberthing maneuvers.

[0004] Therefore, it is known to equip a ship with at least one transverse propulsion device (also known as a motorized propeller) that includes an impeller whose axis of rotation is oriented perpendicular to the plane of symmetry of the ship.

[0005] Lateral propulsion devices are built into channels defined within the ship's hull, which extend from one side of the ship to the other, either at the bow or even the stern.

[0006] To protect the lateral propulsion device from possible collisions or damage, it is known to install grilles or open doors at the entrance of the passageway that houses the lateral propulsion device.

[0007] Compared to grilles, open doors have the advantage that, during cruising, when the lateral propulsion system is not in use, the open doors can be closed to minimize turbulence caused by the passage opening and to optimally cover and protect the lateral propulsion system, and can be opened when the lateral propulsion system is needed.

[0008] A known solution involves mounting the door on multiple through hinges connected to the passageway entrance. Examples of these solutions are described in CN205819525, CN105329405, CN102381439, CN109094715, CN205327529, WO2019 / 220152, and GB782628. These known solutions demonstrate a structure that must be accommodated in appropriate holes, which are formed as recesses at the passageway entrance and welded to the hull as clearly described. Because of the need to weld the frame surrounding and supporting the door to the hull, these known solutions require a design with square, sharp-edged motorized passageway entrances, which generates vortices and turbulence in the fluid flow entering or leaving the passage, resulting in high energy losses.

[0009] The presence of a door at the entrance to the passageway makes maintenance of the lateral propulsion device slow and laborious, as the door prevents maintenance personnel from quickly entering the passageway to intervene in the lateral propulsion device.

[0010] Another known drawback of transverse propulsion is that the doors are in a closed configuration and, during cruising, the doors generate friction and eddy current drag due to the discontinuity of the hull profile at the doors.

[0011] Another known drawback of the transverse propulsion device is that the door is in the open configuration and generates turbulence when the impeller is in use, which affects the operating conditions of the impeller itself. Summary of the Invention

[0012] The object of the present invention is to provide a lateral propulsion device in order to overcome at least some of the disadvantages of the prior art.

[0013] A particular object of the present invention is to provide a lateral propulsion device that facilitates maintenance operations by making it easily accessible to maintenance personnel.

[0014] Another specific object of the present invention is to provide a lateral propulsion device that reduces eddy current drag and friction generated during cruising.

[0015] Another specific object of the present invention is to provide a lateral propulsion device that reduces the generation of turbulent flow, thereby maintaining laminar flow and avoiding boundary layer separation and vortex phenomena during the use of the lateral propulsion device.

[0016] These and other objectives are achieved by means of the ship's lateral propulsion device according to claim 1.

[0043] Referring to the accompanying drawings, the lateral propulsion device is indicated by reference numeral 1.

[0044] The transverse propulsion device 1 of the vessel 2 includes a motor channel 3, which is defined in the hull 4 of the vessel 2 and is adapted to accommodate at least one motor propeller 5.

[0045] The motorway 3 is defined by the channel wall 6, which extends between the first channel entrance 7 and the opposite second channel entrance 8.

[0046] The lateral propulsion device 1 further includes at least one connector 9, which extends from the channel wall 6 at at least one channel inlet 7, 8.

[0047] In addition, the lateral propulsion device 1 includes at least one support structure 10, which includes at least one mating connector 27.

[0048] The support structure 10 is detachably connected to the at least one connector 9 using its at least one mating connector 27.

[0049] The lateral propulsion device 1 further includes at least two closing doors 12, which are shaped such that when in the closed position, at least one channel entrance 7, 8 is completely closed.

[0050] According to one aspect of the invention, at least one support structure 10 includes a hinge 11.

[0051] Furthermore, at least two locking doors 12 are rotatably hinged to hinges 11 of the support structure 10, such that when at least one mating connector 27 of the support structure 10 is separated from at least one connector 9, the locking door 12 and the support structure 10 are separated from the motor access channel 3, thereby allowing access to the motor access channel 3.

[0052] Advantageously, this configuration of the lateral propulsion device 1 facilitates maintenance operations by making it easy for maintenance personnel to access the lateral propulsion device.

[0053] According to an embodiment, the maneuvering passage 3 includes a passage wall 6. The passage wall 6 forms a connecting wall 16 at the passage entrances 7 and 8. The connecting wall 16 is connected to the outer wall 17 of the hull 2.

[0054] By means of the connecting wall 16, any discontinuity or edge between the passage wall 6 and the outer hull wall 17 is avoided, thereby allowing fluid entering or leaving the maneuvering passage 3 to move quickly without vortices or with minimal vortices, which allows for a significant reduction in the ship's forward drag.

[0055] At least one connector 9 fixed to the channel wall 6, at least one removable mating connector 27 (which is also removable) to the support structure 10, and a closing door 12 operably connected to the support structure 10 are provided so that they can be separated from the motor channel 3 together with the support structure 10 without changing the geometry of the connecting wall 16, thereby enabling the maximum hydrodynamic force of the lateral propulsion device 1 and thus the possibility of using the solution on the pre-existing motor channel 3, which is optimized for hydrodynamic efficiency and therefore does not initially have a closing door 12 (this allows for modification of the old solution without a closing door 12).

[0056] Connect the support structure 10 to the connector 9

[0057] According to an embodiment, the shape of at least one mating connector 27 is complementary to the shape of at least one connector 9 so that it can be geometrically connected to at least one connector 9.

[0058] Furthermore, at least one mating connector 27 and at least one connector 9 are shaped such that when the at least one mating connector and the at least one connector are geometrically connected, they define a hydrodynamic shape.

[0059] Advantageously, this hydrodynamic shape reduces the generation of turbulent flow, thereby maintaining laminar flow when using the lateral propulsion device 1.

[0060] According to an embodiment, at least one mating connector 27 can be detachably connected to at least one connector 9 via a threaded connection.

[0061] According to this application, at least one mating connector 27 and at least one geometrically connected connector 9 are locked together by a threaded connection (preferably by a plurality of captive screws 28).

[0062] According to an embodiment, the lateral propulsion device 1 includes at least one pair of connectors 9 positioned relative to each other with respect to the channel inlets 7, 8.

[0063] According to an embodiment, the support structure 10 includes at least one beam 21 that extends between two beam ends.

[0064] Each beam end is configured to form a mating connector 27.

[0065] According to this embodiment, hinges 11 are connected to at least one beam 21 such that each of the hinges 11 defines a door rotation axis 14 located in a plane transverse to the ship.

[0066] According to an embodiment, the support structure 10 includes at least two beams 21 that are substantially parallel to each other.

[0067] According to this embodiment, a hinge 11 positioned on a beam 21 points to a hinge 11 positioned on at least one second beam 21 to form multiple pairs of hinges 11, wherein each pair of hinges 11 defines a door rotation axis 14 located in a plane transverse to the ship.

[0068] According to an embodiment, at least one beam 21 is an airfoil or is shaped into a hydrodynamic shape.

[0069] According to an embodiment, the support structure 10 includes at least one upright member 22 extending between two upright ends. The upright ends are connected to two opposing connectors 9.

[0070] In addition, at least one upright member 22 is connected to at least one beam 21 and is laterally positioned relative to at least one beam 21.

[0071] According to an embodiment, the upright end is connected to the connector 9 via a threaded connection (preferably via multiple external screws).

[0072] According to an embodiment, each upright end is configured to form a mating connector 27 that can be separated from the connector 9.

[0073] According to an embodiment, at least one upright member 22 is an airfoil or is shaped into a hydrodynamic shape.

[0074] According to an embodiment, the support structure 10 includes at least two uprights 22, which are substantially parallel to each other and connected to at least one beam 21.

[0075] According to a preferred embodiment, the support structure 10 includes two beams 21, each beam being connected to two uprights 22 to form a frame, such as, but not necessarily, a quadrilateral frame.

[0076] Connect the closed door 12 to the hinge 11

[0077] The closed door 12 defines the outer surface 29 of the door and the opposite inner surface 30 of the door.

[0078] In the closed configuration, the outer surface 29 of the door faces outward from the motor access channel 3, while the inner surface 30 of the door faces inward from the motor access channel 3.

[0079] According to an embodiment of the invention, the closed door 12 is rotatably hinged to the hinge 11 such that, in the closed configuration, the outer surface 29 of the door is flush with the outer surface 17 of the hull of the vessel 2.

[0080] Advantageously, this positioning of the closing door 12 reduces eddy current drag and vortex formation, and the closing door 12 prevents the water flow from impacting the inner surface of the channel, thus avoiding it from becoming the main source of additional drag generated by the brake.

[0081] According to an embodiment, each locking door 12 forms at least a pair of opposing forked eyelets 33, which surround a hinge 11 for alignment with the hinge 11 for inserting a door rotating pin 34 that rotatably connects the eyelets 33 to the hinge 11.

[0082] According to this embodiment, the closing door 12 is connected to the support structure 10 so that it is located in a plane transverse to the ship when open.

[0083] According to an embodiment, a pair of opposing holes 33 includes a through hole 36 and a threaded hole 37.

[0084] The door pivot pin 34 is configured to pass through the through hole 36 and the hinge 11, and be inserted into the threaded hole 37.

[0085] According to an embodiment, the door rotating pin 34, screwed into the threaded hole 37, protrudes beyond the through hole 36.

[0086] According to this embodiment, the nut 20 is screwed onto the protruding portion of the door rotating pin 34 to secure the hinge of the closed door 12 to at least one hinge 11.

[0087] According to an embodiment, opposite holes 33 are formed in the niche 35 of the closed door 12.

[0088] According to an embodiment, each closed door 12 includes a closed wall 31 and a door frame 32, which are connected to each other.

[0089] According to this embodiment, the eyelet 33 is formed on the door frame 32.

[0090] According to an embodiment, the end wall 31 is shaped to be geometrically connected to the eyelet 33 of the door frame 32.

[0091] According to an embodiment, a first set of closing doors 12 (e.g., having five closing doors 12) is hinged to a support structure 10 such that when the closing doors are partially open and the vessel 2 moves forward, the fluid flow generated by the movement of the vessel 2 tends to further close the first set of closing doors 12.

[0092] Furthermore, a second set of closed doors 12 (e.g., having a single closed door 12) is hinged to the support structure 10 such that when the closed doors are partially opened and when the vessel 2 moves forward, the fluid flow generated by the movement of the vessel 2 tends to open such a second set of closed doors 12.

[0093] According to an embodiment, a group of five doors consists of four doors that tend to close when the ship is moving forward and only one door that tends to open when there is forward movement. Considering that the doors can be fully closed or fully open, the group with more exposed hydrodynamic surface area is dominant, and the system tends to close automatically when the ship is moving forward.

[0094] According to an embodiment, when the closed door 12 is in the open or partially open position, the closed door 12 is an airfoil or is shaped into a hydrodynamic shape.

[0095] Therefore, when the lateral propulsion device 1 moves, this shaping of the closing door 12 restricts the formation of turbulent motion of the fluid passing through the closing door 12.

[0096] According to another embodiment, at least one pair of adjacent closed doors 12 includes an outer door surface 29 and an inner door surface 30.

[0097] In the closed configuration, the outer surface 29 of the door faces outward from the motor access channel 3, while the inner surface 30 of the door faces inward from the motor access channel 3.

[0098] In an open or open configuration, at least one pair of adjacent doors 12 are rotated such that each closed door 12 rotates in opposite directions (i.e., in a counter-rotating manner), so that the corresponding outer surfaces 29 of the doors face each other and the inner surfaces 30 of the doors are opposite each other, thereby forming a hydrodynamic profile (in the combination of two adjacent open doors).

[0099] Close door 12 actuation

[0100] According to an embodiment, the lateral propulsion device 1 includes a door control mechanism 24 configured to move the closed door 12 from a closed position to an open position and vice versa.

[0101] According to an embodiment, at least one closed door 12 forms at least one slot or eyelet 33, which is aligned with at least one hinge 11 disposed in the support structure 10.

[0102] At least one hinge 11 of the support structure 10 is a rotary motor 50, which includes a rotary motor stator 51 and a rotary motor rotor 53.

[0103] The at least one eyelet 33 of the closed door 12 is connected to the rotary motor rotor 53, such that rotational motion is generated in the closed door 12 when the rotary motor rotor 53 rotates.

[0104] According to an embodiment, at least one closed door 12 forms at least one eyelet 33, which is aligned with at least one hinge 11 disposed in the support structure 10.

[0105] The at least one hole 33 of the closed door 12 is a rotary motor 50, which includes a rotary motor stator 51 and a rotary motor rotor 53.

[0106] The at least one hinge 11 includes a slot, and the slot is connected to the rotary motor rotor 53 such that rotational motion is generated in the closed door 12 when the rotary motor rotor 53 rotates.

[0107] According to an embodiment, the rotary motor 50 is a hydraulic motor or an electric motor, which is operably connected to the hull by means of the operating connection of the rotary motor 53.

[0108] According to an embodiment, the rotary motor 50 is a hydraulic motor or an electric motor, which is operably connected to the hull via a releasable connector 54 (e.g., a quick connector 55) by means of a rotary motor 53.

[0109] By providing a rotary motor 50 fixed to the support structure 20 or the closing door 12, the fully external solution can be made unaffected by the actuation mechanism passing through the hull, thereby simplifying the construction, greatly reducing the overall size, and avoiding the movement of sliding parts immersed in seawater.

[0110] According to an embodiment, the actuator (e.g., but not necessarily a linear actuator 38) exits the hull via the motor access channel 3 and is operatively and detachably connected to the door control mechanism 24.

[0111] According to an embodiment, the door control mechanism 24 includes a linear actuator 38 configured to operate along a door actuation axis 26 that is substantially transverse to the door rotation axis 14.

[0112] According to an embodiment, the linear actuator 38 is positioned at the channel entrances 7 and 8 and extends in a sealed manner from the channel wall 6 into the interior of the motor channel 3.

[0113] According to an embodiment, the door control mechanism 24 includes a control bracket 23 which is connected to the linear actuator 38 via a hinged connection.

[0114] The control bracket 23 is further connected to the closed door 12, so that the closed door 12 moves with the movement of the linear actuator 38.

[0115] According to an embodiment of the present invention, the hinged connection between the control bracket 23 and the linear actuator 38 includes a connecting pin 43 that rotatably connects the control bracket 23 to the linear actuator 38.

[0116] According to an embodiment, the control bracket 23 is connected to the locking door 12 via a plurality of control levers 39, which are connected to the locking door 12 and rotatably connected to the control bracket 23.

[0117] Preferably, only one control lever 39 is connected to each closed door 12.

[0118] According to an embodiment, a reversing control lever 41 among a plurality of control levers 39 is connected to a motion reversing connecting rod 40, which is configured to reverse the direction of rotation of a closed door 12 connected to the reversing control lever 41.

[0119] In this way, when the control bracket 23 actuates the control lever 39 to open the closed door 12 in a counterclockwise direction, the motion reversing connecting rod 40 operates the reversing control lever 41 to open the corresponding closed door in a clockwise direction, and vice versa.

[0120] According to an embodiment, the motion reversing connecting rod 40 is pivotally connected to the control rod 42, which is fixed relative to the control bracket 23.

[0121] According to an embodiment, the control bracket 23 is configured to act on the door frame 32 of each closed door 12.

[0122] According to an embodiment of the present invention, the lateral propulsion device 1 includes two control mechanisms 24, which are positioned relative to each other with respect to the channel entrances 7 and 8.

[0123] Advantageously, one of the two control mechanisms 24 is redundant relative to the other control mechanism 24 so as to replace the first control mechanism 24 in case of failure.

[0124] According to an embodiment, the corresponding linear actuators 38 of the two control mechanisms 24 operate along the same door actuation axis 26, such that the forward movement of one linear actuator 38 corresponds to the retraction of the other linear actuator 38.

[0125] According to an embodiment, the first set of locking doors 12 is connected to the control bracket 23 of one of the two control mechanisms 24, while the second set of locking doors 12 is connected to the control bracket 23 of the other control mechanism 24.

[0126] In addition, the control brackets 23 of the two control mechanisms 24 are rotatably connected to each other.

[0127] According to an embodiment, both control mechanisms 24 include a reversing control lever 41, which is connected to the same motion reversing connecting rod 40.

[0128] Advantageously, the two control mechanisms 24 configured in this way cooperate to actuate the closed door 12 during normal operation of both control mechanisms, while in the event of a failure of one of the two control mechanisms 24, the other control mechanism is configured to move all closed doors 12 independently.

[0129] Disassembly tool 44

[0130] According to another aspect of the invention, the assembly kit 45 of the lateral propulsion device 1 includes the lateral propulsion device 1 as previously described and the disassembly tool 44.

[0131] According to an embodiment, the disassembly tool 44 includes two hollow base rails 46, which are configured to be lifted, for example, by a forklift.

[0132] In addition, the dismantling tool 44 includes at least one support column 47, which is transverse to the base track 46 and configured to support at least one mating connector 27 of the transverse propulsion device 1 disengaged from the hull 4 of the vessel 2.

[0133] According to a preferred embodiment, the dismantling tool 44 includes two support columns 47 configured to support at least one beam 21 of the transverse propulsion device 1 detached from the hull 4 of the vessel 2.

[0134] According to an embodiment, the disassembly tool 47 includes a polygonal structure 48 that connects the support post 47 to the base track 46.

[0135] A stop element 49 is formed at the connection between the polygonal structure 48 and the base track 46 to prevent it from detaching from the hull 4 of the vessel 2 and from separating from the lateral propulsion device 1 associated with the dismantling tool 44.
