Description

[Technical field]

[0001] The present invention relates to the field of marine technology, and more particularly to a swinging wing plate structure for providing buoyancy to a ship hull and a ship hull equipped with said wing plate structure. [Background technology]

[0002] The draft of a ship generally refers to the depth to which the ship is submerged in water, which is the vertical distance from the bottom of the hull to where the hull meets the water surface. It indirectly reflects the buoyancy the ship experiences while sailing (i.e. the weight of the ship and its cargo, which is equal to the buoyancy on the hull). Therefore, the deeper the draft of a ship, the greater the ship's carrying capacity.

[0003] However, as the hull draft deepens, the resistance it receives increases, energy consumption increases, and speed is also affected. Therefore, reducing the hull draft while maintaining the stability of the hull is advantageous for reducing energy consumption and increasing speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] In order to make the purpose, technical solution and advantages of the invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below based on the embodiments of the present invention. Obviously, the embodiments described below are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0020] As shown in Figures 1 and 2, the present invention is a swinging wing plate structure for providing buoyancy to a hull, which comprises a portal frame 3 attached to the hull, with vertical slide rails on both sides of the portal frame 3, and a slide plate slidingly connected to the vertical slide rails. A first hydraulic cylinder 5 is attached to the portal frame 3, and a piston rod of the first hydraulic cylinder 5 is connected to the slide plate. A wing plate 6 is attached to the slide plate 4, and ends of the wing plate 6 extend to both sides of the hull body 1.

[0021] It should be noted that in this embodiment, the top of the portal frame 3 is higher than the hull, and the wing plate 6 can be controlled up and down via the first hydraulic cylinder 5. In this embodiment, when the water draft is deep, the wing plate 6 can contact the water surface when it is at its lowest position, and the wing plate 6 is adjusted according to the water draft to keep the lower surface of the wing plate 6 in contact with the water surface.

[0022] The slide plate includes a first slide plate 4 and a second slide plate 11, and there is a fixed connection between the first slide plate 4 and the second slide plate 11. The piston rod of a first hydraulic cylinder is connected to the first slide plate 4.

[0023] The wing plate is movably connected to the second slide plate 11, and the connection structure is a connection frame connected to the second slide plate 11 by a hinge, and a wing plate connected to the connection frame. The first slide plate 4 is provided with a lateral support frame, and a second hydraulic cylinder is hinged to the lateral support frame. The piston rod of the second hydraulic cylinder is hinged to the wing plate.

[0024] The piston rod of the second hydraulic cylinder of the present invention passes between the first slide plate 4 and the second slide plate 11, and a space is maintained to ensure the operation space of the second hydraulic cylinder when the wing plate is raised from a horizontal state to a vertical (vertical) state.

[0025] It should be noted that when the boat speed reaches a certain level, the wing plate 6 is deployed, causing the wing plate 6 to come into contact with the water surface, and the wing plate 6 is lifted by the water current, thereby increasing the buoyancy of the hull main body 1 and improving the boat speed.

[0026] It should be noted that when the piston rod of the first hydraulic cylinder 5 is in the maximum position, the second sliding plate 11 is pushed to the bottom of the receiving groove 2, and when it is in the minimum position, the first sliding plate 4 is pulled up to the top of the receiving groove 2. The piston rod of the second hydraulic cylinder 7 can pull the wing plate from a horizontal position to a vertical position.

[0027] In the present invention, when the wing plate is in a horizontal position, the movable end of the wing plate may rise due to the influence of the water current, and in that case, it is necessary to strongly hold it down with the second hydraulic cylinder. In order to prevent such a situation, the connecting frame is provided with a slide groove 12, a stopper plate (position limiting plate) 13, and a first pulley unit 14.

[0028] As shown in FIG. 2, a positioning ring 15 is provided in the slide groove 12, and a movable locking plate 16 that can slide in the slide groove 12 is provided in the slide groove 12. The movable locking plate 16 passes through the positioning ring 15, and an insertion hole 17 is provided on one side of the movable locking plate 16. An insertion rod 18 is connected to the stopper plate 13, and the insertion rod 18 is inserted into the insertion hole 17. A compression spring 19 is attached to the insertion rod 18, and one end of the compression spring 19 abuts against the stopper plate 13 and the other end abuts against the movable locking plate 16. A pull ring 25 is provided on the movable locking plate 16, and a hoist (winch) 20 is provided on the first slide plate 4. A second pulley unit 21 is provided on the second slide plate 11, and the wire rope of the hoist 20 is connected to the pull ring via the second pulley unit 21 and the first pulley unit 14.

[0029] In the above structure, when the compression spring 19 is in a normal state, the other end of the movable locking plate 16 abuts against the second slide plate 11, and they come into contact on both sides to form a jack block structure. When the movable locking plate 16 moves within the slide groove 12, it always passes through the positioning ring 15, and therefore does not come off from the slide groove 12. When it is necessary to store the wing plate, the hoist 20 is operated to pull the wire rope, pulling the pull ring 25, moving the movable locking plate 16, compressing the compression spring 19, and separating the end face of the movable locking plate 16 from the second slide plate 11, allowing the wing plate to be stored.

[0030] The upper surface of the wing plate 6 is a downwardly curved arched surface, and the lower surface is a stepped (folded) staircase surface, and the stepped portion is connected by an arched surface. The cross section of the wing plate 6 is an arched plate with a downward pushing structure.

[0031] A vertical plate 9 is provided at the free end of the wing plate 6, and a floor board 10 is provided on the lower surface of the wing plate 6. The floor board 10 is arranged parallel to the vertical plate 9.

[0032] 3, the wing plate is an assembled structure of an outer frame 22 and an inner swing plate 23, and the outer frame 22 and the inner swing plate 23 are connected by a hinge. A third hydraulic cylinder 24 is provided on the connecting frame, and a piston rod of the third hydraulic cylinder 24 is connected to the inner swing plate 23 by a hinge.

[0033] The angle of the inner swing plate 23 can be adjusted according to the speed of the water current, thereby improving the buoyancy in accordance with the speed of the water current.

[0034] It should be noted that the first hydraulic cylinder 5, the second hydraulic cylinder 7, and the third hydraulic cylinder 24 can be replaced with air cylinders and controlled through the PLC remote control module. The device that is compatible with the PLC remote control module is a common and existing mature technology, so its electrical connection and specific circuit structure are not described in detail here.

[0035] At the same time, it should be noted that although the present invention preferably uses the first hydraulic cylinder 5, the second hydraulic cylinder 7, and the third hydraulic cylinder 24, devices such as air cylinders and screws can also be used.

[0036] As shown in Figures 4-5, this embodiment also provides a hull structure with wing plates 6 on both sides, which includes a hull body 1, and both sides of the hull body 1 are longitudinal structures, and the front and rear are inclined plates. Both ends of the longitudinal structures on both sides extend to the front and rear inclined plates of the hull body 1, and the lower ends extend to the bottom of the hull body 1.

[0037] The water flow is guided between the longitudinal structures on both sides, and the water flow that passes through the front and rear inclined plates is less likely to spread outside the longitudinal structures, significantly reducing waves caused by water breaking.

[0038] The hull body 1 has a receiving groove 2 on both sides thereof, and the wing plate structure is installed in the receiving groove 2.

[0039] The longitudinal structures on both sides reduce waves, and more importantly, reduce the impact of waves on the wing plate 6. In the prior art, although the structure of the wing plate 6 is added to the hull, the water surface may become unstable due to the presence of waves, making it impossible to use the wing plate. The wing plate 6 requires a stable water surface, and the lower surface of the wing plate 6 is located below the water surface and the upper surface is located above the water surface, so that the water flow passing through the wing plate 6 is utilized to lift the wing plate 6, thereby increasing the buoyancy of the hull.
