Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a wind deflector and a container ship. Background Art

[0002] The resistance encountered by ships during operation can be divided into wind resistance and water resistance due to different fluid media. In terms of wind resistance, there are two main factors that change the wind resistance of ships. One is that different stacking modes lead to different wind loads; the other is to change the wind resistance by setting a wind deflector at the bow. Among them, container ships have a larger windward area than other ship types, so the wind resistance is more obvious and the energy consumption is higher. However, the wind deflector in the existing technology is not effective in reducing wind resistance. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of large wind resistance and large energy consumption during the operation of ships in the prior art, and to provide a wind deflector and a container ship.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a wind deflector, which is a curved surface structure arranged at the bow of a hull, and comprises a main body portion, the width of which gradually widens from the front to the rear of the hull, and the main body portion extends from the bow to the top of the hull;

[0006] The main body part includes two side surfaces and a windward surface located on both sides of the hull, the two sides of the windward surface are respectively connected to the two side surfaces, a downwardly recessed recess is provided in the middle of the windward surface, the recess is provided in the middle of the width direction of the hull, the shape of the recess is V-shaped, and the upper edge of the main body part is streamlined.

[0007] In this scheme, a wind guide cover is set at the bow of the hull, and the wind guide cover includes a main part. The width of the main part gradually widens from the front to the rear of the hull, and the main part extends from the bow to the top of the hull, thereby preventing the wind from blowing directly on the cargo at the rear and causing high pressure in some areas, so that the airflow behind the wind guide cover fits the cargo on the ship, reducing the wind resistance during the operation of the hull, and can reduce the energy consumption during the operation of the ship. The wind guide cover adopts a curved structure to make the surface of the wind guide cover smoother and the effect of guiding the wind direction is better.

[0008] The main part includes two side surfaces and a windward surface on both sides of the hull. The two sides of the windward surface are connected to the two side surfaces respectively. A recessed notch is provided in the middle of the windward surface. The notch is provided in the middle of the width direction of the hull. The shape of the notch is V-shaped, so that a mast can be provided at the opening to reduce the interference of the wind deflector on the mast. The upper edge of the main part is streamlined, so that the edge of the wind deflector is smoother, the effect of reducing wind resistance is better, and the appearance of the ship is more dynamic and more beautiful. In addition, the wind deflector can also serve as a wave-breaking board of the ship, reducing the bow waves and improving safety and comfort.

[0009] Preferably, the height of the windward surface increases from the middle of the main body portion to both sides.

[0010] In this scheme, by increasing the height of the windward surface from the middle of the main part to both sides, the height of the windward surface on both sides is made higher, so that the wind direction on both sides can be fully guided, so that the wind guide cover can better reduce the wind resistance during the operation of the hull and reduce the energy consumption during the operation of the ship.

[0011] Preferably, the height of the sides decreases from the front to the rear of the hull.

[0012] In this solution, by reducing the height of the side from the front to the rear of the hull, the lateral projection area is reduced, which is conducive to reducing the lateral wind resistance, so that the wind deflector can better reduce the wind resistance of the hull during operation and reduce the energy consumption of the ship during operation. At the same time, it can reduce the amount of materials used on the two sides, improve the structural strength, and save costs.

[0013] Preferably, the main body portion extends obliquely toward the rear of the hull in a direction from the bottom of the hull to the top of the hull.

[0014] In the present scheme, by tilting and extending the main body toward the rear of the hull from the bottom of the hull to the top of the hull, when the wind blows towards the wind guide cover, the airflow can be lifted upward, so that the airflow can avoid the cargo behind the wind guide cover, and the shape of the wind guide cover can be more in line with the direction of wind flow, so that the wind guide cover can better reduce the wind resistance during the operation of the hull and reduce the energy consumption during the operation of the ship.

[0015] Preferably, the inclination angle formed by the main body portion and the horizontal plane ranges from 50° to 80°.

[0016] In this solution, by setting the size of the inclination angle within a reasonable range, the shape of the wind guide cover is more in line with the wind flow direction, avoiding poor wind-guiding effect caused by too large or too small inclination angle. The size of the inclination angle can be selected according to different ship models, which is more flexible.

[0017] Preferably, the wind guide cover also includes a transition portion, which is connected to the bottom of the main body portion, and the shape of the upper edge of the transition portion matches the shape of the lower edge of the main body portion. In the height direction of the hull, the transition portion extends vertically upward from the bow away from the bow.

[0018] In this solution, the wind deflector further includes a transition part, which is connected to the bottom of the main part. The transition part cooperates with the main part, so that the wind deflector has a better effect of reducing wind resistance. By adjusting the height of the transition part, a better combination of the transition part and the main part can be found, so that the wind resistance is lower. The shape of the upper edge of the transition part matches the shape of the lower edge of the main part, so that the transition part and the main part can be better connected, and the strength of the wind deflector is enhanced. The transition part extends vertically upward from the bow away from the bow, so that the transition part has a better effect of increasing the height. By adjusting the height of the transition part, a better combination of the transition part and the main part can be found, so that the wind resistance is lower.

[0019] Preferably, the wind deflector further comprises a forecastle portion, the forecastle portion is connected to the lower portion of the transition portion, the shape of the lower edge of the forecastle portion matches the shape of the bow, and the shape of the upper edge of the forecastle portion matches the shape of the lower edge of the transition portion;

[0020] And / or, in the height direction of the hull, the forecastle portion extends obliquely from the bow away from the bow toward the outer side of the hull.

[0021] In this solution, the wind deflector also includes a forecastle part, which is connected to the bottom of the transition part. The forecastle part can also serve as the forecastle of the ship. The shape of the lower edge of the forecastle part matches the shape of the bow, so that the forecastle part is better connected to the bow. The shape of the upper edge of the forecastle part matches the shape of the lower edge of the transition part, so that the forecastle part and the transition part can be better connected, thereby enhancing the strength of the wind deflector. By extending the forecastle part from the bow away from the bow toward the outside of the hull, the width of the wind deflector is increased to match the widest part of the hull, so that the wind deflector has a better effect of reducing wind resistance.

[0022] The present invention also provides a container ship, comprising the above-mentioned wind deflector.

[0023] Preferably, the container ship further comprises a mast, and the mast is arranged at the recess.

[0024] In this solution, the container ship also includes a mast, and the interference of the wind deflector on the mast is reduced by arranging the mast in the recess.

[0025] Preferably, the container ship further comprises a container, and the container is arranged behind the wind deflector, and the maximum height of the wind deflector is smaller than the height of the container.

[0026] In this solution, by making the maximum height of the air guide cover smaller than the height of the container, it is avoided that the air guide cover is too high to increase the resistance, and at the same time, the material used for the air guide cover can be reduced, thereby reducing the cost.

[0027] The positive and progressive effects of the present invention are:

[0028] A wind deflector is set at the bow of the hull, and the wind deflector includes a main part. The width of the main part gradually widens from the front to the rear of the hull, and the main part extends from the bow to the top of the hull, thereby preventing the wind from blowing directly on the cargo at the rear and causing high pressure in some areas, so that the airflow behind the wind deflector fits the cargo on the ship, reducing the wind resistance during the operation of the hull, and can reduce the energy consumption during the operation of the ship. The wind deflector adopts a curved structure, which makes the surface of the wind deflector smoother and the effect of guiding the wind direction is better.

[0029] The main body includes two side surfaces and a windward surface located on both sides of the hull. The two sides of the windward surface are respectively connected to the two side surfaces. A recessed notch is provided in the middle of the windward surface. The notch is provided in the middle of the width direction of the ship. The shape of the notch is V-shaped, so that a mast can be provided at the opening to reduce the interference of the wind deflector on the mast. The upper edge of the main body is streamlined, so that the edge of the wind deflector is smoother, the effect of reducing wind resistance is better, and the appearance of the ship is more dynamic and the shape is more beautiful. In addition, the wind deflector can also serve as a wave-breaking board of the ship, reducing the bow waves and improving safety and comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Container 300 DETAILED DESCRIPTION

[0050] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the following examples.

[0051] The present embodiment provides a container ship 100, which includes a wind deflector 200 and a container 300. The container 300 is arranged behind the wind deflector 200. The wind deflector 200 is provided to divert the wind blowing directly on the container 300, thereby reducing the wind resistance on the container ship 100 and achieving the effect of energy saving and emission reduction.

[0052] like Figure 1-Figure 4 As shown, the wind deflector 200 is a curved structure arranged at the bow 112 of the hull 110. The wind deflector 200 includes a main body 210. The width of the main body 210 gradually widens from the front to the rear of the hull 110. The main body 210 extends from the bow 112 to the top of the hull 110, thereby preventing the wind from blowing directly on the cargo at the rear and causing high pressure in some areas, so that the airflow behind the wind deflector 200 fits the cargo on the ship, reducing the wind resistance of the hull 110 during operation, and reducing the energy consumption of the ship during operation. The wind deflector 200 adopts a curved structure, which makes the surface of the wind deflector 200 smoother and the effect of guiding the wind direction is better.

[0053] The main body 210 includes two side surfaces 212 and a windward surface 211 located on both sides of the hull 110. The two sides of the windward surface 211 are connected to the two side surfaces 212 respectively. A recessed notch 213 is provided in the middle of the windward surface 211. The notch 213 is provided in the middle of the width direction of the hull 110. The shape of the notch 213 is V-shaped. The container ship 100 also includes a mast, which is provided at the notch 213, thereby reducing the interference of the wind deflector 200 on the mast. The upper edge of the main body 210 is streamlined, so that the edge of the wind deflector 200 is smoother, the effect of reducing wind resistance is better, and the appearance of the ship is more dynamic and more beautiful. In addition, the wind deflector 200 can also serve as a wave-breaking board of the ship, reducing the bow waves and improving safety and comfort.

[0054] In this embodiment, the air guide cover 200 is disposed symmetrically. In other embodiments, the air guide cover 200 may also be disposed asymmetrically.

[0055] The height of the windward surface 211 increases from the middle of the main body 210 to both sides, so that the heights of both sides of the windward surface 211 are higher, thereby being able to fully guide the wind direction on both sides, so that the wind guide cover 200 can better reduce the wind resistance of the hull 110 during operation and reduce energy consumption during ship operation.

[0056] The height of the side surface 212 decreases from the front to the rear of the hull 110, reducing the lateral projection area, thereby reducing the lateral wind resistance, making the wind deflector 200 more effective in reducing the wind resistance of the hull 110 during operation, and reducing the energy consumption during the operation of the ship. At the same time, the amount of material used for the two side surfaces 212 can be reduced, the structural strength can be improved, and the cost can be saved.

[0057] like Figure 3 As shown, in this embodiment, the upper edge of the main body 210 is symmetrically arranged in an S shape, and the wind guide cover 200 is significantly reduced in height at both sides and remains relatively stable at the bottom with a small height change, thereby significantly reducing the area of ​​the side 212, and further reducing resistance in crosswinds. In other embodiments, other shapes deemed appropriate by those skilled in the art may also be selected.

[0058] Along the direction from the bottom of the hull 110 to the top of the hull 110, the main body 210 extends obliquely toward the rear of the hull 110, so that when the wind blows towards the wind guide cover 200, the airflow can be lifted upward, allowing the airflow to avoid the cargo behind the wind guide cover 200, making the shape of the wind guide cover 200 more in line with the direction of wind flow, so that the wind guide cover 200 can better reduce the wind resistance of the hull 110 during operation, thereby reducing energy consumption during ship operation.

[0059] The inclination angle formed by the main body 210 and the horizontal plane ranges from 50° to 80°. A high inclination angle can lift the airflow upward. By setting the inclination angle within a reasonable range, the shape of the wind deflector 200 can better conform to the wind flow direction, avoiding a poor wind deflection effect caused by an inclination angle that is too large or too small. The inclination angle can be selected according to different ship models, which is more flexible. Figure 3 As shown, in this embodiment, the inclination angle A is 65.3°. In other embodiments, those skilled in the art can select a suitable inclination angle according to specific circumstances.

[0060] The wind deflector 200 further includes a transition portion 220, which is connected to the lower part of the main body 210. The shape of the upper edge of the transition portion 220 matches the shape of the lower edge of the main body 210. In the height direction of the hull 110, the wind deflector 200 has a better effect of reducing wind resistance. By adjusting the height of the transition portion 220, a better combination of the transition portion 220 and the main body 210 can be found to reduce wind resistance. The shape of the upper edge of the transition portion 220 matches the shape of the lower edge of the main body 210, so that the transition portion 220 and the main body 210 can be better connected, thereby enhancing the strength of the wind deflector 200. In the height direction of the hull 110, the transition portion 220 extends vertically upward from the bow 112 to away from the bow 112, so that the transition portion 220 has a better effect of increasing the height. By adjusting the height of the transition portion 220, a better combination of the transition portion 220 and the main body 210 can be found to reduce wind resistance.

[0061] The wind deflector 200 further includes a forecastle portion 230, which is connected to the bottom of the transition portion 220. The forecastle portion 230 can also serve as the forecastle of the ship. The shape of the lower edge of the forecastle portion 230 matches the shape of the bow 112, so that the forecastle portion 230 is better connected to the bow 112. The shape of the upper edge of the forecastle portion 230 matches the shape of the lower edge of the transition portion 220, so that the forecastle portion 230 and the transition portion 220 can be better connected, thereby enhancing the strength of the wind deflector 200.

[0062] In the height direction of the hull 110, the forecastle part 230 extends obliquely from the bow 112 to the outside of the hull 110 away from the bow 112, thereby increasing the width of the wind deflector 200 to match it with the widest part of the hull 110, so that the wind deflector 200 can better reduce wind resistance.

[0063] like Figure 2 As shown, the maximum width of the lower end of the forecastle part 230 is B1, the maximum width of the upper end of the forecastle part 230 is B2, and the maximum width of the hull 110 is B, wherein B1<B2<B.

[0064] The maximum height of the air guide cover 200 is smaller than the height of the container 300, thereby preventing the air guide cover 200 from being too high and increasing resistance, and at the same time reducing the material used for the air guide cover 200 and reducing costs.

[0065] like Figure 2 As shown, the height of the forecastle part 230 is H1, the height of the transition part 220 is H2, the maximum height of the main part 210 is H3 (H3=max{H31, H32, H33, H34}), and the height of the container 300 behind the air scoop 200 is H, wherein H1+H2+H3<H.

[0066] like Figure 2 As shown, the height of the middle point a of the main body portion 210 is relatively low, where the height is H31, and a deeper V-shaped notch 213 is formed in the middle. The main body portion 210 gradually increases in height at point b, with a height of H32, and then the main body portion 210 decreases in height at point c, with a height of H33. Finally, the main body portion 210 turns to point d, with a height of H34, H32>H31>H32 / H34.

[0067] In this embodiment, H34=1.55*H33, which can be changed within 0.3*H33≤H34≤3*H33 according to different ship types. max{H34,H31}=0.3*H32, which can be changed within 0.1*0.32≤max{H34,H31}≤0.6*H32 according to different ship types.

[0068] The widths at a, b, and c are B31, B32, and B33, respectively, and B31>B32>B33. In this embodiment, B32=0.7*B31, and can be changed within 0.25*H33≤H34≤0.9*H33 according to different ship types.

[0069] like Figure 3 As shown, the distance between the lower rear end of the wind deflector 200 and the bow 112 is L1, the distance between the upper part of the wind deflector 200 and the rear end is L2, the distance between the central symmetrical point a and the rear end is L31, the distance between the highest point b and the rear end is L32, and the distance between the end low point c and the rear end is L33, wherein L1≥L2>L31>L32>L33. In this embodiment, L32=0.8*L31, and can be changed in the range of 0.3*L31≤L32≤0.95*L31 according to different ship types.

[0070] like Figure 4 As shown, the upper and lower ends of the wind deflector 200 are both in smooth arc shape. The top of the superstructure is shorter in length and narrower in width than the bottom, with a smooth transition, and the slope gradually becomes gentler from the width of the ship to the middle of the ship.

[0071] like Figure 5 and Figure 6As shown in the velocity flow field in FIG. 1 , different colors represent different wind speeds. Before the wind guide cover 200 is installed, the airflow disturbance on the top of the container 300 is obvious and has a large impact range. After the wind guide cover 200 is installed, the airflow is more smoothly guided from the bow 112 to the container 300. The flow field fits the container 300 body and the disturbance range is relatively small, thereby achieving the purpose of reducing wind resistance.

[0072] like Figure 7 and Figure 8 It can be seen from the resistance curve that at the bow 112 wind direction, the wind resistance can be reduced by 22% after installing the wind deflector 200, and the effect of reducing the wind resistance is obvious.
