The windshield of the container ship is formed as a curved plate-like structure arranged around the bow 101 of the hull 100. Specifically, the windshield of the container ship includes a wind guide portion 10, and the width of the wind guide portion 10 gradually widens from the front to the rear of the hull 100, and the wind guide portion 10 gradually tilts from bottom to top toward the direction close to the hull 100, so that the end of the wind guide portion 10 away from the container 200 (that is, the front end of the wind guide portion 10) is formed into a structure similar to a tip, so that the airflow facing the wind guide is lifted and blown above the container 200, so that the windshield of the container ship has the effect of guiding the wind flow in front to the wind. It should be noted that the width of the wind guide portion 10 is Figure 2 Horizontal direction of viewing angle.

[0060] Furthermore, in this embodiment, if Figure 2 As shown, the height of the wind guide 10 increases first and then decreases from the middle to both sides, so that the top of the wind guide 10 forms a double convex structure in the vertical direction, so that the airflow is smoother and fits the flow of the container 200, and the disturbance range is small, so as to achieve the purpose of reducing wind resistance, effectively reduce energy consumption in ship operation, and achieve energy conservation and emission reduction. In addition, the windshield of the container ship is visually dynamic and beautiful, and can replace the original wave-breaking board structure, reduce the bow 101 from rising waves, and improve the safety and comfort of the ship.

[0061] Furthermore, in this embodiment, if Figure 2 As shown, the minimum dimension of the air guide portion 10 in the height direction is located on the edge 12 of the air guide portion 10 close to the container 200, that is, the height dimension marked H33 in the figure is the minimum dimension of the air guide portion 10, the position marked H31 is the position of the center line 11 of the air guide portion 10, the air guide portion 10 is symmetrical in the width direction with the center line 11 as the axis, the position marked H32 is the highest position of the air guide portion 10, H32>H31 / H32, so that the top of the air guide portion 10 forms a double convex structure in the vertical direction.

[0062] In this embodiment, if Figure 3 As shown, in the length direction of the hull 100 (i.e. Figure 3The minimum distance between the center line 11 and the edge 12 of the wind guide 10 close to the container 200 is L1, the minimum distance between the highest position of the wind guide 10 and the edge 12 of the wind guide 10 close to the container 200 is L2, and the size of the wind guide 10 in the length direction of the hull 100 is L3, L3>L1>L2, so that the highest position of the wind guide 10 is located between the center line 11 and the edge 12 of the wind guide 10, which is conducive to guiding and reducing resistance. It can also reduce the material used and improve the structural strength.

[0063] In this embodiment, the windshield of the container ship may be made of a steel structure or new materials (such as fiberglass, carbon fiber, etc.).

[0064] In this embodiment, if Figures 1 to 4 As shown, the container ship windshield also includes a first forecastle portion 21 arranged below the wind guide portion 10, and the first forecastle portion 21 gradually inclines from bottom to top in a direction away from the container 200. The first forecastle portion 21 is installed on the bow 101 and the lower edge of the first forecastle portion 21 is adapted to the shape of the bow 101, thereby facilitating the fixed connection of the wind guide portion 10.

[0065] Furthermore, in this embodiment, if Figures 1 to 4 As shown, the container ship windshield also includes a second forecastle portion 22 arranged between the first forecastle portion 21 and the wind guide portion 10. The second forecastle portion 22 is formed as an arc-shaped curved surface structure. The upper edge and the lower edge of the second forecastle portion 22 have the same shape and size, so as to facilitate the adjustment of the height of the wind guide portion 10 to improve the effect of reducing wind resistance.

[0066] In a preferred embodiment, Figure 2 As shown, the height dimension of the first forecastle 21 is H1, the height dimension of the second forecastle 22 is H2, and the maximum height dimension of the wind guide 10 is H3, that is, H3=max{H31,H32,H33}. H1+H2+H3<the height dimension of the container 200 exceeding the deck, so that the airflow is smoother and ensures that the wind flow blowing through the wind guide 10 can be more in line with the flow of the container 200, and the airflow disturbance range is small to achieve the purpose of effectively building wind resistance on the container 200 ship, saving energy and reducing emissions.

[0067] In addition, in this embodiment, Figure 2 As shown, the dimension of the first forecastle 21 in the width direction of the hull 100 is B1, the dimension of the second forecastle 22 in the width direction of the hull 100 is B2, and B1<B2<the maximum width dimension of the hull 100.

[0068] In this embodiment, if Figure 3As shown, the center line 11 of the air guide portion 10 gradually tilts from bottom to top to a first preset angle A1, A1 = 50°~80°, for example, A = 67.1°, so that when wind blows towards the air guide portion 10, the angle A1 setting can effectively lift the airflow upward to reduce wind resistance.

[0069] In this embodiment, if Figure 4 As shown, the top of the air guide portion 10 is a smooth arc.

[0070] See also Figure 5 and Figure 6 As shown in the comparison, before the container ship windshield is installed, the airflow disturbance on the top of the container 200 is obvious and has a large impact range. After the container ship windshield is installed, the airflow is smoother and fits the container 200, and the disturbance range is smaller. In addition, see Figure 7 and Figure 8 As shown in the comparison, the wind resistance in the X direction (ie, the length direction of the hull 100) can be reduced by 18%, thereby proving that the windshield of the container ship of this embodiment can effectively reduce the wind resistance after installation.

[0071] Embodiment 2

[0072] In this embodiment, if Figures 9 to 12 As shown, the windshield of the container ship is installed at the bow 101 of the hull 100, and the container 200 on the hull 100 is arranged behind the windshield of the container ship, so that the windshield of the container ship can guide the gas in front of the container 200 to reduce wind resistance. The windshield of the container ship is formed as a curved plate-like structure arranged around the bow 101 of the hull 100. Specifically, the windshield of the container ship includes a wind guide portion 10, and the width of the wind guide portion 10 gradually widens from the front to the rear of the hull 100, and the wind guide portion 10 gradually tilts from bottom to top toward the direction close to the hull 100, so that the end of the wind guide portion 10 away from the container 200 (that is, the front end of the wind guide portion 10) is formed into a structure similar to a tip, so that the airflow facing the wind guide is lifted and blown above the container 200, so that the windshield of the container ship has the effect of guiding the wind flow in front to the wind. It should be noted that the width of the wind guide portion 10 is Fig.10 Horizontal direction of viewing angle.

In addition, the windshield of the container ship is visually dynamic and beautiful in shape, which can replace the original wave-breaking board structure, reduce the bow 101 from rising waves, and improve the safety and comfort of the ship.

[0074] Furthermore, in this embodiment, if Figure 2 As shown, the minimum dimension of the air guide 10 in the height direction is located between the edge 12 of the air guide 10 close to the container 200 and the position of the air guide 10 with the maximum dimension in the height direction. Specifically, the air guide 10 is symmetrical in the width direction with the center line 11 as the axis.

[0077] In this embodiment, if Figures 9 to 12As shown, the container ship windshield also includes a first forecastle portion 21 arranged below the wind guide portion 10, and the first forecastle portion 21 gradually inclines from bottom to top in a direction away from the container 200. The first forecastle portion 21 is installed on the bow 101 and the lower edge of the first forecastle portion 21 is adapted to the shape of the bow 101, thereby facilitating the fixed connection of the wind guide portion 10.

[0078] Furthermore, in this embodiment, if Figures 9 to 12 As shown, the container ship windshield also includes a second forecastle portion 22 arranged between the first forecastle portion 21 and the wind guide portion 10. The second forecastle portion 22 is formed as an arc-shaped curved surface structure. The upper edge and the lower edge of the second forecastle portion 22 have the same shape and size, so as to facilitate the adjustment of the height of the wind guide portion 10 to improve the effect of reducing wind resistance.

H1+H2+H3<the height dimension of the container 200 exceeding the deck, so that the airflow is smoother and ensures that the wind flow blowing through the wind guide 10 can be more in line with the flow of the container 200, and the airflow disturbance range is small to achieve the purpose of effectively building wind resistance on the container 200 ship, saving energy and reducing emissions.

[0080] In this embodiment, if Fig.11 As shown, in the length direction of the hull 100 (i.e. Fig.11 The minimum distance between point a and the edge 12 of the wind guide 10 close to the container 200 is L31, the minimum distance between point b and the edge 12 of the wind guide 10 close to the container 200 is L32, and the minimum distance between point c and the edge 12 of the wind guide 10 close to the container 200 is L33.

[0081] In this embodiment, the windshield of the container ship may be made of a steel structure or new materials (such as fiberglass, carbon fiber, etc.).

[0082] In addition, in this embodiment, Fig.10As shown, the dimension of the first forecastle 21 in the width direction of the hull 100 is B1, the dimension of the second forecastle 22 in the width direction of the hull 100 is B2, and B1<B2<the maximum width dimension of the hull 100.

The container ship windshield is formed as a curved plate-like structure surrounding the bow 101 of the hull 100. Specifically, the container ship windshield includes a wind guide portion 10, and the width of the wind guide portion 10 gradually widens from the front to the rear of the hull 100, and the wind guide portion 10 gradually tilts from bottom to top toward the direction close to the hull 100, so that the end of the wind guide portion 10 away from the container 200 (that is, the front end of the wind guide portion 10) is formed into a structure similar to a tip; thereby achieving the effect of guiding the wind flow in front to the wind from the container ship windshield. It should be noted that the width of the wind guide portion 10 is Fig.18 The horizontal direction under the viewing angle is the width direction of the hull 100 .

[0088] In this embodiment, the air guide portion 10 is bilaterally symmetrical in the width direction with the center line 11 as the axis.

[0089] Furthermore, in this embodiment, if Figures 19 to 21As shown, in the horizontal direction, the top of the wind guide 10 is bent from the middle to both sides first in the direction away from the container 200 and then in the direction close to the container 200, so that the top of the wind guide 10 is a plane formed into an M-shaped structure, and a double convex structure is formed on the side of the M-shaped structure facing away from the container 200, so that the air at different positions is more smoothly guided to the rear, so that the airflow blowing in front of the bow 101 smoothly transitions to the container 200, reducing the obvious turbulence generated when the airflow blows directly to the container 200, thereby reducing energy dissipation. In addition, the windshield of the container ship is visually dynamic and beautiful in shape, and can replace the original wave-breaking board structure, reduce the bow 101 from rising waves, and improve the safety and comfort of the ship.

[0090] It should be noted that Fig. 20 and Fig.21 Two different air guide 10 structures are shown, the difference between the two is Fig. 20 The first structure shown is formed into a sharp angle at the center line 11, and the curvature of the arc portion in the M-shaped structure is greater, while Fig.21 The second structure shown is formed into an arc shape in the center line 11 area, so that the M-shaped structure transitions more gently and smoothly.

[0091] Specifically, Fig. 20 As shown, the wind guide 10 is in the length direction of the hull 100 (i.e. Fig. 20 and Fig.21 The dimension of the M-shaped structure in the horizontal direction of the viewing angle is L1, the distance between the highest point (i.e., the most protruding position) in the length direction of the hull 100 and the edge 12 of the wind guide 10 facing the container 200 is L2, and the distance between the center line 11 and the edge 12 of the wind guide 10 facing the container 200 in the length direction of the hull 100 is L3, L1>L2>L3.

[0092] In this embodiment, if Fig.19 As shown, the center line 11 at the bottom of the wind guide portion 10 is inclined to a first preset angle A1, and the center line 11 at the top of the wind guide portion 10 is inclined to a second preset angle A2, A2>A1, so that the center line 11 of the wind guide portion 10 is formed into a curved arc, so that the airflow is directed upward at a larger angle, and combined with the double convex structure in the M-shaped structure, the container ship windshield can have a smaller height as a whole to achieve overall smooth guidance.

[0093] In this embodiment, in the length direction of the hull 100 , the minimum distance between the center line 11 of the wind deflector 10 and the container 200 is greater than the minimum distance between the edges 12 at both ends of the wind deflector 10 in the width direction and the container 200 .

[0094] In this embodiment, if Figures 17 to 21As shown, the container ship windshield also includes a first forecastle portion 21 arranged below the wind guide portion 10, and the first forecastle portion 21 gradually inclines from bottom to top in a direction away from the container 200. The first forecastle portion 21 is installed on the bow 101 and the lower edge of the first forecastle portion 21 is adapted to the shape of the bow 101, thereby facilitating the fixed connection of the wind guide portion 10.

[0095] Furthermore, in this embodiment, if Figures 17 to 21 As shown, the container ship windshield also includes a second forecastle portion 22 arranged between the first forecastle portion 21 and the wind guide portion 10. The second forecastle portion 22 is formed as an arc-shaped curved surface structure. The upper edge and the lower edge of the second forecastle portion 22 have the same shape and size, so as to facilitate the adjustment of the height of the wind guide portion 10 to improve the effect of reducing wind resistance.

[0096] In this embodiment, if Fig.18 As shown, in the width direction of the hull 100 , the maximum width dimension of the wind guide portion 10 is B2 , the minimum width dimension of the first forecastle portion 21 is B1 , and B1 < B2 < the maximum dimension of the hull 100 in the width direction.

[0097] In this embodiment, if Fig.18 As shown, the height dimension of the first forecastle 21 is H1, the height dimension of the second forecastle 22 is H2, the height dimension of the wind guide 10 is H3, and H1+H2+H3<0.6×the height dimension of the container 200 exceeding the deck. It should be noted that, compared with the above-mentioned embodiments 1 and 2, this embodiment can effectively reduce the height dimension of the windshield of the container ship, thereby saving costs.

[0098] See also Fig. 22 and Fig.23 As shown in the comparison, the high pressure area at the bow 101 of the container ship 200 is obvious. After installing the wind shield of the container ship, the range and peak value of the high pressure area are reduced; see Fig.24 and Fig.25 As shown in the comparison, before the container ship windshield is installed, the airflow disturbance on the top of the container 200 is obvious and has a large impact range. After the container ship windshield is installed, the airflow is smoother and fits the container 200, and the disturbance range is smaller, thereby achieving the purpose of reducing energy dissipation and wind resistance; in addition, see Fig.26 and Fig. 27 As shown in the comparison, the wind resistance in the X direction (ie, the length direction of the hull 100) can be reduced by 20%, thereby proving that the windshield of the container ship of this embodiment can effectively reduce the wind resistance after installation.

[0099] According to the present invention, the windshield of the container ship is formed as a curved plate-shaped structure surrounding the bow of the hull, and the container on the hull is arranged behind the windshield of the container ship. The windshield of the container ship includes a wind guide portion, the width of the wind guide portion gradually widens from the front to the rear of the hull, and the wind guide portion gradually tilts from bottom to top in the direction close to the hull; the height dimension of the wind guide portion increases first from the middle to the two sides and then decreases, so that the top of the wind guide portion is formed into a double convex structure in the vertical direction; or the top of the wind guide portion is first bent from the middle to the two sides in the direction away from the container and then bent in the direction close to the container, so that the top of the wind guide is a plane formed into an M-shaped structure. Due to the setting of the windshield, the wind blowing directly on the container is diverted, so that the airflow is smoother and fits the container, and the disturbance range is small, so as to achieve the purpose of reducing wind resistance, effectively reduce the energy consumption in the operation of the ship, and achieve the effect of energy saving and emission reduction. In addition, the windshield of the container ship is visually dynamic and beautiful in shape, and can replace the original wave-breaking board structure, reduce the bow waves, and improve the safety and comfort of the ship.

[0100] A second aspect of the present invention provides a ship, comprising the container ship windshield as described above, and thus having all the beneficial effects of the container ship windshield, which will not be described in detail herein.
