Description

Technical Field

[0001] The invention relates to the technical field of ship equipment, in particular to a bow wind guide device. Background Art

[0002] Energy conservation and emission reduction in the field of ships and seas are receiving more and more attention. The International Maritime Organization, including my country, is also actively promoting the implementation of EEXI (Energy Efficiency Existing Ship Index). In the past, research on drag reduction and energy saving mainly focused on reducing the water resistance of ships. However, in recent years, we have begun to pay more attention to the details of ship drag reduction and energy saving, and the wind load of ships has received more and more attention. Especially for container ships with a large volume above the waterline, research on reducing ship wind resistance is particularly important. At the same time, reducing operating costs and improving ship energy efficiency have always been the common goals pursued by the shipping industry. From the fundamental purpose of energy conservation and emission reduction, research on reducing ship wind resistance is imperative. From the 700-1000TEU loading capacity in the 1960s to the current maximum loading capacity of 24136TEU, the size of container ships has continued to increase. Because there are multiple layers of containers stacked above the deck, the windward volume is large. After continuous improvements in the hull line and propulsion system in the hydrodynamics department, reducing wind resistance has become a new entry point for energy conservation and emission reduction of container ships. Therefore, it is necessary to design an energy-saving device to reduce wind resistance. Without affecting its loading capacity, the energy-saving device needs to guide the air flow from the front of the bow, taking into account the conditions such as the layout of the foremast, the mechanical layout and mooring working environment at the forecastle deck or main deck, and the blind spot of the cab. Summary of the invention

[0003] In view of the above problems in the prior art, the present application provides a bow wind guide device, which can reduce wind resistance and avoid blocking the view of the cab.

[0004] The present application provides a bow wind guide device, comprising: a supporting structure, which is installed at the bow position; an air guide cover, which is installed on the supporting structure, and covers the bow of the ship and is in the shape of a curved surface extending backwards, a concave portion is provided at the middle position of the top of the air guide cover, so that the air guide cover forms a gap in the middle position when viewed in the front and rear directions of the ship, the highest point of the air guide cover is located below the highest point of the first row of containers on the deck of the ship, and the bottom of the concave portion is located below the minimum requirement for the ship's maneuvering and observation line of sight.

[0005] By adopting the above structure, a wind guide cover is set at the bow position, and the wind guide cover is set to a curved surface extending backward, so that the airflow can be guided to the rear, reducing the pressure of the airflow hitting the main windward surface of the hull, improving the uniformity of the airflow around the hull deck, thereby reducing wind resistance, and can also replace the wave plate to prevent waves from hitting the box. By setting a concave part at the middle position of the top of the wind guide cover, the highest point of the wind guide cover is located below the highest point of the first row of containers on the deck of the ship, and the bottom of the concave part is located below the minimum requirement of the ship's operation and observation line of sight, so that the wind guide cover can avoid blocking the operation and observation line of sight, and meet the requirements of the operation and observation line of sight. At the same time, by supporting the wind guide cover with a supporting structure to guide the airflow, the structure of the bow wind guide device can be simplified, the weight of the bow wind guide device can be reduced, and the difficulty of processing and manufacturing can be reduced.

[0006] In some embodiments, the bottom of the concave portion extends from the mid-longitudinal section position of the ship to both sides, and in the maneuvering observation sight line at the bottom of the concave portion, the angles between the sight line at the mid-longitudinal section position of the ship and the sight lines at both ends of the bottom of the concave portion are respectively greater than or equal to 2.5 degrees.

[0007] By adopting the above structure, in the control observation line of sight at the bottom of the recessed portion, the angles between the line of sight located at the mid-longitudinal section of the ship and the lines of sight located at the two end positions of the bottom of the recessed portion are respectively greater than or equal to 2.5 degrees, thereby avoiding obstruction of the control observation line of sight by the wind guide cover, and making the wind guide cover meet the requirements of the control observation line of sight.

[0008] In some embodiments, the lower edge of the wind deflector is adapted to the shape of the upper edge of the bow bulwark.

[0009] By adopting the above structure, the lower edge of the wind guide cover is matched with the upper edge of the bow side wall, so that the connection between the wind guide cover and the bow side wall can be smoother, and the structure of the bow side wall can be avoided to be changed during installation. Therefore, the difficulty of installing the bow wind guide device can be reduced.

[0010] In some embodiments, the wind deflector is composed of a plurality of curved surfaces, and the plurality of curved surfaces are symmetrically arranged along a mid-longitudinal section of the ship.

[0011] With the above structure, the wind guide cover is composed of multiple curved surfaces, and the multiple curved surfaces are symmetrically arranged along the middle longitudinal section of the ship, so that the design and processing of the wind guide cover can be facilitated. Therefore, the processing and manufacturing difficulty of the wind guide cover can be further reduced.

[0012] In some embodiments, the wind deflector includes: a first curved surface, which is arranged at the bottom of the wind deflector and vertically arranged along the bow bulwark.

[0013] With the above structure, by vertically arranging the first curved surface along the bow bulwark, the space between the wind deflector and the bow deck can be increased, thereby avoiding interference with the mooring operation of the crew at the bow position.

[0015] By adopting the above structure, there can be enough space between the wind deflector and the bow deck to avoid interference with the mooring operation of the crew at the bow. At the same time, it can also avoid the increase of wind resistance due to the wind deflector being too high.

[0016] In some embodiments, the first curved surface is provided with openings, and the openings are provided at positions corresponding to mooring operations on the ship.

[0017] With the above structure, by setting an opening on the first curved surface, it is convenient for the crew to perform mooring operations at the bow position.

[0018] In some embodiments, the wind guide cover also includes a second curved surface, a third curved surface and a fourth curved surface, and the first curved surface, the second curved surface, the third curved surface and the fourth curved surface are arranged in pairs and are symmetrically arranged on both sides of the mid-longitudinal section of the ship; the fourth curved surface is located at the top position of the wind guide cover, and the second curved surface and the third curved surface are located between the first curved surface and the second curved surface, and are arranged in the horizontal direction.

[0019] In some embodiments, the supporting structure includes: a vertical girder, a plurality of which are vertically arranged on the bow; and a horizontal girder, a plurality of which are horizontally arranged on the vertical girder; wherein the wind guide cover is arranged on the vertical girder and the horizontal girder.

[0038] Below, in conjunction with the accompanying drawings, the specific structure of the bow wind guide device 10 in the present application is exemplarily described.

[0039] like Figure 1 , Figure 2As shown, the present application provides a bow wind guide device 10, including a support structure 100 and a wind guide cover 200. Among them, the support structure 100 is installed at the position of the bow 21, and the wind guide cover 200 is installed on the support structure 100. The wind guide cover 200 covers the bow 21 and is in the shape of a curved surface extending backward. A recessed portion 250 is provided at the middle position of the top of the wind guide cover 200, so that the wind guide cover 200 forms a gap in the middle position when viewed along the front and rear direction of the ship 20. The highest point of the wind guide cover 200 is located below the highest point of the first row of containers on the deck of the ship 20 (i.e., the row of containers closest to the wind guide cover), and the bottom of the recessed portion 250 is located below the minimum requirement for the maneuvering and observation line of sight of the ship 20. Therefore, by setting the wind guide cover 200 at the bow 21, and setting the wind guide cover 200 to a curved surface extending backward, the airflow can be guided backward, the pressure of the airflow hitting the main windward surface of the hull can be reduced, the uniformity of the airflow around the deck of the hull can be improved, and the wind resistance can be reduced. It can also replace the wave-breaking board to prevent the waves from hitting the box. By setting the lower concave part 250 at the middle position of the top of the wind guide cover 200, the highest point of the wind guide cover 200 is located below the highest point of the cargo on the deck of the ship 20, and the bottom of the lower concave part 250 is located below the minimum requirement of the operation and observation line of sight of the ship 20, so that the wind guide cover 200 can be avoided from blocking the operation and observation line of sight, and the requirements of the operation and observation line of sight can be met. At the same time, by supporting the wind guide cover 200 with the support structure 100 to guide the airflow, the structure of the bow wind guide device 10 can be simplified, the weight of the bow wind guide device 10 can be reduced, and the difficulty of processing and manufacturing can be reduced.

[0040] In some embodiments, Figure 3 , Figure 4 As shown, the bottom of the lower concave portion 250 extends from the position of the middle longitudinal section P of the ship 20 to both sides, and in the control observation line of sight at the bottom of the lower concave portion 250, the angles between the line of sight at the position of the middle longitudinal section P of the ship 20 and the line of sight at the two ends of the bottom of the lower concave portion 250 are respectively greater than or equal to 2.5 degrees. Therefore, by making the angles between the line of sight at the position of the middle longitudinal section P of the ship 20 and the line of sight at the two ends of the bottom of the lower concave portion 250 in the control observation line of sight at the bottom of the lower concave portion 250 greater than or equal to 2.5 degrees, it is possible to avoid the wind guide cover 200 from blocking the control observation line of sight, so that the wind guide cover 200 meets the control observation line of sight requirements.

[0041] In some embodiments, Figure 2 As shown, the lower edge of the wind guide cover 200 is matched with the upper edge of the bulwark 22 of the bow 21. Therefore, by making the lower edge of the wind guide cover 200 match the upper edge of the bulwark 22 of the bow 21, the connection between the wind guide cover 200 and the bulwark 22 of the bow 21 can be smoother, avoiding the need to change the structure of the bulwark 22 of the bow 21 during installation. Therefore, the difficulty of installing the bow wind guide device 10 can be reduced.

[0042] In some embodiments, Figure 1 , Figure 3-Figure 5 As shown, the wind guide cover 200 is composed of a plurality of curved surfaces, and the plurality of curved surfaces are symmetrically arranged along the middle longitudinal section P of the ship 20. Thus, by making the wind guide cover 200 composed of a plurality of curved surfaces, and making the plurality of curved surfaces symmetrically arranged along the middle longitudinal section P of the ship 20, the design and processing of the wind guide cover 200 can be facilitated. Thus, the processing and manufacturing difficulty of the wind guide cover 200 can be further reduced.

[0043] In some embodiments, Figure 1 , Figure 3-Figure 5 As shown, the wind deflector 200 includes a first curved surface 210, which is disposed at the bottom of the wind deflector 200 and vertically disposed along the bulwark 22 of the bow 21. Thus, by vertically disposing the first curved surface 210 along the bulwark 22 of the bow 21, the space between the wind deflector 200 and the deck of the bow 21 can be increased, thereby avoiding interference with the mooring operation of the crew at the bow 21.

[0044] In some embodiments, the first curved surface 210 extends upward from the bulwark 22 of the bow 21 by 1000 mm to 1500 mm. Thus, there is enough space between the wind deflector 200 and the deck of the bow 21 to avoid interference with the mooring operation of the crew at the bow 21. At the same time, it can also avoid increasing wind resistance due to the wind deflector 200 being too high.

[0045] In some embodiments, Figure 2 As shown, the first curved surface 210 is provided with an opening 211, and the opening 211 is provided at a corresponding position for mooring the ship 20. Thus, by providing the opening 211 on the first curved surface 210, it is convenient for the crew to perform mooring operations at the bow 21 position.

[0046] In some embodiments, Figure 1 , Figure 3-Figure 5 As shown, the wind deflector 200 further includes a second curved surface 220, a third curved surface 230 and a fourth curved surface 240. The first curved surface 210, the second curved surface 220, the third curved surface 230 and the fourth curved surface 240 are arranged in pairs, and are symmetrically arranged on both sides of the mid-longitudinal section P of the ship 20. The fourth curved surface 240 is located at the top of the wind deflector 200, and the second curved surface 220 and the third curved surface 230 are located between the first curved surface 210 and the second curved surface 220, and are arranged in the horizontal direction.

[0047] In some embodiments, Figure 2 , Figure 6 , Figure 7As shown, the support structure 100 includes a vertical girder 110 and a horizontal girder 120. A plurality of vertical girder 110 are provided, which are vertically arranged on the bow 21 (i.e., the plane where the vertical girder 110 is located is vertically arranged, perpendicular to the deck of the bow 21). A plurality of horizontal girder 120 are provided, which are horizontally arranged on the vertical girder 110. Among them, the wind guide cover 200 is arranged on the vertical girder 110 and the horizontal girder 120. Therefore, by arranging the vertical girder 110 and the horizontal girder 120, the wind guide cover 200 is arranged on the vertical girder 110 and the horizontal girder 120, so that the wind guide cover 200 can be easily installed, and the firmness and stability of the wind guide cover 200 are improved.

[0048] In some embodiments, Figure 2 , Figure 8 As shown, the support structure 100 further includes a plurality of reinforcing frames 130, and the reinforcing frames 130 are vertically arranged to connect the plurality of horizontal girders 120. Thus, by arranging the reinforcing frames 130 between the horizontal girders 120, the support capacity of the air scoop 200 can be improved, thereby improving the firmness and stability of the air scoop 200.

[0049] The above content is an exemplary description of a possible embodiment of the bow wind guide device 10. Next, in conjunction with the accompanying drawings, a specific embodiment of the bow wind guide device 10 is described in detail.

[0050] Figure 1 It is a schematic diagram of the side structure of the bow wind guide device 10 after installation in the present application. Figure 2 for Figure 1 A side perspective schematic diagram of the bow wind guide device 10 of the midship. Figure 1 , Figure 2 As shown, the bow wind guide device 10 in this embodiment is installed on the bow 21 of the ship 20, and is used to guide the airflow to reduce wind resistance. Among them, the ship 20 is a container ship 30, and a plurality of containers 30 are stacked in the middle position of the ship 20. A cab is provided at the stern of the ship 20 for controlling the ship 20. The bow 21 of the ship 20 is provided with devices such as anchors, and the crew performs mooring work at the bow 21. The bow wind guide device 10 includes a support structure 100 and a wind guide cover 200, the support structure 100 is installed at the bow 21, and the wind guide cover 200 is installed on the support structure 100. The wind guide cover 200 covers the bow 21 and is in the shape of a curved surface extending backward. In this way, the airflow can be guided backward, the pressure of the airflow hitting the main windward surface of the hull is reduced, the uniformity of the airflow around the deck of the hull is improved, thereby reducing wind resistance, and it can also replace the wave board to prevent waves from hitting the box.

[0051] Figure 3 for Figure 1The front side orthographic structural diagram of the middle air guide cover 200 shows the structure of the left half of the air guide cover 200. Figure 3 As shown, the wind guide cover 200 includes a first curved surface 210, a second curved surface 220, a third curved surface 230 and a fourth curved surface 240. The first curved surface 210, the second curved surface 220, the third curved surface 230 and the fourth curved surface 240 are arranged in pairs, and are symmetrically arranged on both sides of the middle longitudinal section P of the ship 20, and are spliced ​​to form the wind guide cover 200. Among them, the first curved surface 210 is arranged at the bottom position of the wind guide cover 200, the fourth curved surface 240 is arranged at the top position of the wind guide cover 200, and the second curved surface 220 and the third curved surface 230 are arranged between the first curved surface 210 and the fourth curved surface 240. The paired first curved surface 210, the second curved surface 220 and the fourth curved surface 240 are connected at the middle longitudinal section P of the ship 20, respectively, and the paired third curved surface 230 is respectively located at the two sides of the paired second curved surface 220 separated from each other.

[0052] like Figure 1-Figure 3 As shown, the first curved surface 210 is vertically arranged along the bulwark 22 of the bow 21 to increase the space between the wind deflector 200 and the deck of the bow 21, so as to avoid interference with the mooring operation of the crew at the bow 21. The first curved surface 210 extends upward from the bulwark 22 of the bow 21 by 1000mm-1500mm. There is enough space between the wind deflector 200 and the deck of the bow 21, so as to avoid interference with the mooring operation of the crew at the bow 21. At the same time, it can also avoid the increase of wind resistance due to the wind deflector 200 being too high.

[0053] like Figure 2 As shown, the shape of the lower edge of the first curved surface 210 is adapted to the shape of the upper edge of the bulwark 22 of the bow 21, so that the connection between the wind deflector 200 and the bulwark 22 of the bow 21 can be smoother, avoiding the need to change the structure of the bulwark 22 of the bow 21 during installation. Thus, the difficulty of installing the bow wind deflector 10 can be reduced. The upper edge of the first curved surface 210 is kept horizontal, so that the connection position between the first curved surface 210 and the second curved surface 220 and the third curved surface 230 can be smoother, thereby reducing the design difficulty of the wind deflector 200. The first curved surface 210 is also provided with an opening 211, which is provided at a corresponding position for mooring the ship 20. Thus, it is convenient for the crew to perform mooring operations at the bow 21.

[0054] Figure 4 is a schematic diagram of characteristic lines of the air guide cover 200 in the YZ coordinate system; Figure 5 Schematic diagram of characteristic lines of the air guide cover 200 in the XZ coordinate system, wherein the X direction is the front-rear direction of the ship 20, the Y direction is the left-right direction of the ship 20, and the Z direction is the up-down direction. Figure 4, the characteristic lines of the left half of the air scoop 200 are shown. The right half of the air scoop 200 is symmetrical to the left half, so the right half is omitted.

[0055] like Figure 4 , Figure 5 As shown, the front and left orthographic projections of the second curved surface 220 are quadrilaterals, that is, Figure 4 , Figure 5 The front and left sides of the third curved surface 230 are projected as a quadrilateral, that is, Figure 4 , Figure 5 The front and left orthographic projections of the fourth curved surface 240 are hexagonal, that is, Figure 4 , Figure 5 The area shown in EFJIHG.

[0056] like Figure 4 , Figure 5 As shown, JIHG in the fourth curved surface 240 is the upper edge of the fourth curved surface 240. Figure 4 As shown, the upper edge of the fourth curved surface 240 is recessed downward to form a recessed portion 250. Among them, HG is the bottom of the recessed portion 250, and HG is below the minimum requirement for the maneuvering observation line of sight of the ship 20. In this way, the wind deflector 200 can avoid the maneuvering observation line of sight of the ship 20 in the up and down directions, so as not to affect the maneuvering field of sight of the ship 20. The two side edges JIH of the recessed portion 250 gradually move upward from the bottom of the recessed portion 250 away from the position of the middle longitudinal section P of the ship 20, that is, the recessed portion 250 increases in size as it moves upward. In the maneuvering observation line of sight at the bottom of the recessed portion 250, the angle between the line of sight at the G position and the line of sight at the H position is greater than or equal to 2.5 degrees. In this way, the wind deflector 200 can avoid the maneuvering observation line of sight of the ship 20 in the left and right directions, so as not to affect the maneuvering field of sight of the ship 20. In addition, combined with Figure 1 It can be seen that the highest point J node of the fourth curved surface 240 is located below the highest point of the first row of containers 30 on the ship 20. Therefore, the wind guide cover 200 can be further prevented from protruding from above the container 30, thereby avoiding affecting the maneuvering vision of the ship 20.

[0057] like Figure 4 As shown, in the YZ coordinate plane, the distance between node C and point B is 3 / 4-2 / 3 of the distance between D and point B. HI and FJ have the same angle, that is, in the YZ coordinate plane, HI and FJ are parallel. Thus, the shape of the wind deflector 200 can be adjusted according to the different shapes of the bow 21 of the ship 20, the wind deflector performance can be adjusted, and the adaptation range of the wind deflector 200 can be improved.

[0058] like Figure 4 As shown in , in the YZ coordinate plane, the angle between DJ and the vertical line is α, and the angle range is 0°~30°. Figure 5 As shown, in the XZ coordinate plane, the angle between EB and the vertical line is γ, and the range of the γ angle is -15° to -60°. The angle between GE and the extended line of BE is θ, and the θ angle increases by 0° to 30° on the basis of the BE angle, that is, GE is more vertical than BE. The height of point F is 100mm-400mm less than that of point G. The angle between CF and the vertical line is β, and the β angle is 0° to -60°. The connection point (EF) of the angle line of the wind guide cover 200 is smooth, and CF and FJ are straight lines in space. Therefore, the shape of the wind guide cover 200 can be adjusted according to the different shapes of the bow 21 of the ship 20, the wind guiding performance can be adjusted, and the adaptation range of the wind guide cover 200 can be improved.

[0059] Figure 6 for Figure 2 A schematic structural diagram of the middle horizontal girder 120; Figure 7 for Figure 2 A schematic diagram of the structure of the middle vertical girder 110, Figure 8 for Figure 2 The structural diagram of the middle reinforcing frame 130 is shown in FIG. Figure 6-Figure 8 As shown, the support structure 100 includes a vertical girder 110, a horizontal girder 120 and a reinforcing frame 130. Among them, a plurality of vertical girder 110 are provided, and are evenly arranged along the bulwark 22 of the bow 21. The vertical girder 110 is fixedly installed on the deck of the bow 21 or on the bulwark 22. The vertical girder 110 is bent in a vertical plane according to the shape of the wind deflector 200, and the angle between the planes where different vertical girder 110 are located changes with the curvature of the bulwark 22 of the bow 21. A plurality of horizontal girder 120 are provided, and are horizontally arranged on the vertical girder 110. The horizontal girder 120 is bent in the horizontal plane according to the shape of the wind deflector 200, and the distance between two adjacent horizontal girder 120 is approximately equal. In this way, the wind deflector 200 can be fixed in the horizontal and vertical directions, so as to improve the firmness and stability of the wind deflector 200. In addition, a plurality of reinforcing frame 130 are provided, and are arranged on the horizontal girder 120. The reinforcing frame 130 is bent on a vertical plane along the shape of the wind deflector 200, and the angle between the planes where different reinforcing frame 130 are located varies along the curvature of the bow 21 bulwark 22. The reinforcing frame 130 is fixedly connected to the horizontal beams 120 at the corresponding positions one by one, the top of the reinforcing frame 130 is fixedly connected to the uppermost horizontal beam 120 at the corresponding position, and the bottom is fixedly connected to the lowermost horizontal beam 120 at the corresponding position, providing support for the wind deflector 200. Thus, the firmness and stability of the wind deflector 200 can be improved.
