Description

Technical Field

[0001] The invention belongs to the field of ship supplies, and in particular relates to a windshield structure used for the bow of an ultra-large container ship. Background Art

[0002] Large container ships are ships specially used to carry international standard containers. They have the advantages of large cargo capacity, high loading and unloading efficiency, and low transportation cost. These ships are usually large in size and can carry thousands of containers to meet the needs of large-scale cargo transportation. When ultra-large container ships are fully loaded in severe sea conditions, waves may directly knock down or damage the containers loaded at the front; sea breezes may blow directly on the containers and may blow down the front containers; container ships will be subject to huge wind resistance when sailing against the wind, which will increase the fuel consumption of the ship.

[0003] For this reason, the windbreak structure of ultra-large container ships came into being as an energy-saving device installed at the bow, aiming to reduce the wind resistance of the ship during sailing, thereby reducing fuel consumption and carbon emissions. In terms of application, since Mitsui OSK Lines opened the precedent of application, many shipping companies have followed suit, gradually expanding from the initial small and medium-sized container ships to ultra-large container ships with a carrying capacity of about 20,000 TEU. Not only are new ships more considered for installation when they are built, but a large number of active ships have also been modified.

[0004] However, the existing windshield structures of ultra-large container ships are generally too heavy, which will increase the overall weight of the ship, causing the ship to consume more fuel to overcome the additional resistance during navigation, which not only increases operating costs but also aggravates environmental pollution; and the existing windshield structures of ultra-large container ships fail to fully consider the characteristics of air flow in their design, resulting in additional resistance during navigation, which will not only increase the fuel consumption of the ship but may also affect the navigation speed and stability of the ship; in addition, the existing windshield structures of ultra-large container ships cannot be adjusted in height and angle, and cannot be raised or rotated to a certain angle in case of severe weather, such as strong winds and high waves, so as to better protect the carried containers from the impact of waves.

DETAILED DESCRIPTION

[0018] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figures 1 to 16 The embodiment of the present invention provides a windshield structure for the bow of an ultra-large container ship. Figure 1 Schematic diagram of the overall structure of an embodiment of the present invention, as shown in Figures 2 to 4 As shown, the windshield structure for the bow of a super-large container ship includes a streamlined cladding 1, which is a smooth and continuous curved shell structure. The streamlined cladding 1 is the main body of the windshield structure and is used for windshielding of super-large container ships. A plurality of vertical strong structures 2 are uniformly welded longitudinally inside the streamlined cladding 1, and a plurality of horizontal strong structures 7 are uniformly welded transversely inside the streamlined cladding 1. The vertical strong structures 2 and the horizontal strong structures 7 are staggered to form a solid support network.

[0020] The vertical strong structure 2 is the key support part in the windshield structure, providing the necessary strength and stability. The horizontal strong structure 7 is the horizontal support member in the windshield structure. The vertical strong structure 2 and the horizontal strong structure 7 are staggered to form a solid support system to support the streamlined package 1, which is conducive to the stable windshield effect of the streamlined package 1. The streamlined package 1 is also welded with several rows of vertical profiles 3 attached to its inner surface in the longitudinal direction. The vertical profile 3 is smaller in volume and weight than the vertical strong structure 2. The vertical profile 3 plays a role in assisting the support of the streamlined package 1 while achieving a lightweight design.

[0021] like Figures 2 to 4 As shown, a plurality of large vertical brackets 4 are welded at the lower part of the interior of the streamlined package plate 1, each large vertical bracket 4 corresponds to each column of vertical profiles 3 up and down, and a connecting bracket 6 is connected between each large vertical bracket 4 and each column of vertical profiles 3, and a transition structure 5 is welded at the position where the connecting bracket 6 and the transition structure 5 intersect each column of vertical profiles 3 below the horizontal strong structure 7, and both the connecting bracket 6 and the transition structure 5 are designed as triangular structures, which makes the connection support more stable.

[0022] like Figure 1 to Figure 2 As shown, a top surface twisting connection structure 8 is fixedly connected to the top of the vertical strong structure 2. The top surface twisting connection structure 8 is an irregular curved shell structure adapted to the top surface of the streamlined cladding 1, which is used to block wind and water on the top surface of the windproof structure, and is conducive to protecting the supporting structure of the streamlined cladding 1 below. The top surface twisting connection structure 8 is tightly fitted to the top surface of the streamlined cladding 1. A top surface crescent plate 9 is arranged in the top surface twisting connection structure 8 above each vertical profile 3. The design of the top surface twisting connection structure 8 helps to maintain the integrity and stability of the structure, and can absorb and disperse the impact force or pressure from above. The top surface crescent plate 9 plays a role in supporting the top surface twisting connection structure 8. A height adjustment mechanism 10 is welded below the streamlined cladding 1.

[0023] like Figure 8As shown, the height adjustment mechanism 10 includes a tooth plate 1001, a tooth structure 1111 is provided on one side of the tooth plate 1001, an adjusting gear 1007 is meshedly connected to one side of the tooth structure 1111, an output end of a first reduction motor 1008 is passed through the center of the adjusting gear 1007, the first reduction motor 1008 is in a fixed state, a lifting plate 1006 is rotatably connected below the tooth plate 1001, a fixed bottom plate 1005 is provided below the lifting plate 1006, and two groups of first curved side plates 1002, second curved side plates 1003 and third curved side plates 1004 are symmetrically provided on the outer side between the tooth plate 1001 and the fixed bottom plate 1005. When encountering a hurricane diagonally in front, the first reduction motor 1008 is used as a power source. When the first reduction motor 1008 is started, it can drive the adjusting gear 1007 to rotate forward or reverse, so that the adjusting gear 1007 engages with the toothed structure 1111 for transmission, so that the tooth plate 1001 drives the windshield structure with the streamlined wrapping plate 1 as the main body to rotate a certain angle relative to the lifting plate 1006, thereby adjusting the direction of the windshield structure according to the wind direction, which is conducive to achieving a better windshield effect.

[0024] like Figure 8 As shown, the tooth plate 1001 and the lifting plate 1006 are used to support the upper windshield structure mainly composed of the streamlined package plate 1, and the fixed bottom plate 1005 is the base of the height adjustment mechanism 10, providing a stable support surface to ensure that the entire mechanism can be firmly installed on a horizontal plane. A plurality of hydraulic jacks 11 are arranged between the lifting plate 1006 and the fixed bottom plate 1005. The hydraulic jacks 11 are used to lift the tooth plate 1001 and the windshield structure on it through the lifting plate 1006, so as to achieve the height adjustment of the windshield structure, which is conducive to adjusting the height of the windshield structure according to the weather conditions at sea, so as to protect the carried containers from the impact of waves.

[0025] like Figures 9 to 11As shown, two motor fixing frames 12 are symmetrically fixedly installed between the lifting plate 1006 and the fixed bottom plate 1005, and a second reduction motor 13 is fixedly installed in each motor fixing frame 12. The output end of each second reduction motor 13 is sleeved with a driving gear 14, and one side of the driving gear 14 is meshedly connected with a forward transmission lifting mechanism 15, and the other side of the forward transmission lifting mechanism 15 is meshedly connected with a reverse transmission lifting mechanism 16, and the other side of the reverse transmission lifting mechanism 16 is also meshedly connected with another group of forward transmission lifting mechanisms 15, and so on. The forward transmission lifting mechanisms 15 and the reverse transmission lifting mechanisms 16 are staggered and meshed with each other, and the number of the meshed forward transmission lifting mechanisms 15 and the reverse transmission lifting mechanisms 16 is determined according to actual needs. The forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 both include a driven gear 151, and the driving gear 14 is meshed with the driven gear 151. The forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 are also meshed and connected through their respective driven gears 151. A column bracket 152 is penetrated through the center of each driven gear 151, and a threaded column 154 is threadedly connected to the inside of each column bracket 152. A top plate 153 is welded on the top of each threaded column 154. The difference between the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 is that the rotation direction of the threads of the threaded columns 154 of the two are opposite.

[0026] The second reduction motor 13 is used as a power source. The second reduction motor 13 is started, and its output end drives the driving gear 14 to rotate. The driving gear 14 engages with the driven gear 151 to rotate. The rotation of the driven gear 151 drives the internal column bracket 152 to rotate. The rotation of the column bracket 152 causes the threaded column 154 connected with the internal thread to rotate relative to the column bracket 152 and move upward, thereby dragging the upper top plate 153 to move upward. Since the rotation of the driven gear 151 drives the adjacent driven gear 151 to rotate in the opposite direction, since each forward transmission lifting mechanism 15 and each reverse transmission lifting mechanism 16 are adjacent and staggered, and the rotation directions of the threads of the threaded column 154 of the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 are opposite, each threaded column 154 can simultaneously drag the top plate 153 to move upward, and the rising speed of the top plate 153 is the same as the jacking speed of the hydraulic jack 11, thereby realizing the auxiliary jacking and support function of the jacking plate 1006.

[0027] In certain preferred embodiments, Fig.12 As shown ( Fig.12Taking the internal structure of the first curved side panel 1002 as an example, the internal structures of the second curved side panel 1003 and the third curved side panel 1004 are the same). The first curved side panel 1002, the second curved side panel 1003 and the third curved side panel 1004 are all slidably connected with the inner windshield 17. The first curved side panel 1002, the second curved side panel 1003 and the third curved side panel 1004 are all provided with a fixed bonding plate 18 in the center. A plurality of balls 181 are embedded and installed on one side of the fixed bonding plate 18, and the inner windshield 17 and the balls 181 are rollingly connected. The inner windshield 17 is used to cooperate with the windshield structure to adjust the height and realize the rise or fall with the lifting plate 1006 to ensure the airtightness of the adjustment mechanism 10. The combination of the fixed bonding plate 18 and the balls 181 is conducive to the inner windshield 17 to slide up and down more smoothly, reducing wear and noise.

[0028] In certain preferred embodiments, Figures 5 and 6 As shown, the streamlined cladding 1 includes a first cladding 101, and second cladding plates 102 are fixedly installed on both sides of the first cladding 101, and a third cladding plate 103 is fixedly installed on the other side of each second cladding plate 102. The first cladding plate 101, the second cladding plate 102 and the third cladding plate 103 together constitute a streamlined shell-shaped smooth curved surface design with a low middle part at the upper end and high sides at both ends of the streamlined cladding 1. This structure is conducive to reducing wind resistance, so as to adapt to wind flow and guide it to flow smoothly through the hull, thereby reducing energy consumption and improving navigation efficiency.

[0029] In certain preferred embodiments, Figure 2 As shown, the vertical strong structure 2 is a longitudinal support structure, and a plurality of vertical strong structures 2 are designed with various lengths and curved surfaces, and are adapted to fit the inner curved surface of the shell of the streamlined cladding 1. As the main supporting member, the vertical strong structure 2 is responsible for bearing and transmitting longitudinal loads and stresses, and ensuring the stability and safety of the entire streamlined cladding 1 structure.

[0030] In certain preferred embodiments, Figure 2 As shown, the horizontal strong structure 7 is a lateral support structure, and a plurality of horizontal strong structures 7 are adapted to fit the inner curved surface of the shell of the streamlined cladding 1 by adopting various lengths and curved surfaces. As a lateral support structure, the horizontal strong structure 7 is mainly responsible for enhancing the stability and bearing capacity of the streamlined cladding 1 in the horizontal direction.

[0031] In certain preferred embodiments, Fig. 9 As shown, the driving gear 14, the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 are all rotatably connected to the fixed base plate 1005. This ensures that the driving gear 14, the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 can only rotate relative to the fixed base plate 1005 and cannot move in other directions.

[0032] In certain preferred embodiments, Fig.12 As shown, the top surface of the inner windshield plate 17 is welded to the lower surface of the lifting plate 1006, and the lower surfaces of the first curved side plate 1002, the second curved side plate 1003 and the third curved side plate 1004 are all welded to the fixed bottom plate 1005 to ensure that only the inner windshield plate 17 moves with the lifting plate 1006.

[0033] In certain preferred embodiments, Figure 8 As shown, two adjusting slots 1009 are symmetrically provided at both ends of the tooth plate 1001, and an adjusting twist 1010 is slidably connected in each adjusting slot 1009, and each adjusting twist 1010 is welded on the lifting plate 1006. The tooth plate 1001 and the lifting plate 1006 are slidably connected through the adjusting slots 1009 and the adjusting twist 1010, that is, when the adjusting gear 1007 is engaged with the toothed structure 1111 for transmission, the tooth plate 1001 moves, and the lifting plate 1006 remains stationary, so that the adjusting slot 1009 slides relative to the adjusting twist 1010, and the rotation of the tooth plate 1001 relative to the lifting plate 1006 is realized, and the sliding adjustment angle of the adjusting twist 1010 in the adjusting slot 1009 is the rotation angle of the tooth plate 1001 relative to the lifting plate 1006.

[0034] In certain preferred embodiments, Figures 13 to 16 As shown, the lower end of the vertical large toggle plate 4 is also buckled with an auxiliary fixing structure 19, and the auxiliary fixing structure 19 is provided with a pressing groove 191 adapted to the protruding structure at the lower end of the vertical large toggle plate 4, and the protruding structure at the lower end of the vertical large toggle plate 4 is placed in the pressing groove 191, and a clamping block 192 is welded on the lower surface of the auxiliary fixing structure 19, and a avoiding slide groove 1011 is further provided on the tooth plate 1001 below the clamping block 192, and it is ensured that the opening of the avoiding slide groove 1011 does not affect the rotation of the tooth plate 1001 relative to the lifting plate 1006, and the clamping block 192 passes through the tooth plate 1001 The avoidance groove 1011 passes through the lifting plate 1006 (that is, the lifting plate 1006 is also provided with an avoidance groove 1011), and the thickness of the clamping block 192 is equal to the thickness of the tooth plate 1001 plus the lifting plate 1006, a protruding block 193 is welded below the clamping block 192, springs 194 are welded on both sides of the protruding block 193, and a stopper 195 is welded at the other end of each spring 194, and the sum of the thickness of the protruding block 193, the length of the two springs 194 compressed to the shortest state and the thickness of the two stoppers 195 is equal to the thickness of the clamping block 192.

[0035] After the height adjustment mechanism 10 is welded on the streamlined package plate 1, in order to achieve better connection and fixation between the height adjustment mechanism 10 passing through the tooth plate 1001 and the lower height adjustment mechanism, the two blocks 195 are squeezed inward to compress the spring 194 to the shortest state, and the protruding block 193, the spring 194 and the block 195 are passed through the avoidance slide groove 1011 and the through holes on the lifting plate 1006 and pushed downward until the clamping block 192 is completely inserted into the lifting plate 1006. At this time, the block 195 is no longer squeezed, and the spring 194 drives the block 195 to naturally bounce open. The upper surface of the block 195 is against the lower surface of the lifting plate 1006, realizing the upper and lower direction limitation of the auxiliary fixing structure 19. At the same time, the auxiliary fixing structure 19 is tightly pressed on the protruding structure at the lower end of the vertical large toggle plate 4 through the pressing groove 191, realizing the auxiliary connection and fixation function of the height adjustment mechanism 10 and the streamlined package plate 1.

[0036] In the above embodiment, a method for adjusting the height of a windshield structure for the bow of an ultra-large container ship includes: when encountering severe weather, such as strong winds and large waves, it is necessary to raise the windshield to increase its stability and reduce the impact of wind resistance on the navigation of the ship, a plurality of hydraulic jacks 11 are simultaneously started to drag the jacking plate 1006 upward, and the jacking plate 1006 drives the windshield structure with the streamlined package plate 1 as the main body to move upward through the tooth plate 1001, and at the same time, each inner windshield plate 17 moves upward with the jacking plate 1006, and while the inner windshield plate 17 slides upward relative to the first curved side plate 1002, the second curved side plate 1003 and the third curved side plate 1004, the ball 181 forms a rolling contact with the inner windshield plate 17 to reduce friction, and at the same time the second deceleration plate 1001 is driven by the gear plate 1001 to drive the windshield structure with the streamlined package plate 1 as the main body to move upward, and at the same time, each inner windshield plate 17 moves upward with the jacking plate 1006. The motor 13 is started, and the output end of the second reduction motor 13 drives the driving gear 14 to rotate, and the driving gear 14 meshes with the driven gear 151 to rotate. The rotation of the driven gear 151 drives the internal column bracket 152 to rotate, and the rotation of the column bracket 152 causes the threaded column 154 connected with the internal thread to drag the top plate 153 to move upward, and the rotation of the driven gear 151 drives the adjacent driven gear 151 to rotate in the opposite direction. Since the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 are staggered, and the rotation directions of the threads of the threaded column 154 of the forward transmission lifting mechanism 15 and the reverse transmission lifting mechanism 16 are opposite, each threaded column 154 can drag the top plate 153 to move upward at the same time, and the rising speed of the top plate 153 is the same as the lifting speed of the hydraulic jack 11.

[0037] When encountering a hurricane blowing diagonally from the front, the first reduction motor 1008 is started to drive the adjusting gear 1007 to rotate forward or reverse, so that the adjusting gear 1007 engages with the toothed structure 1111 for transmission, thereby causing the toothed plate 1001 to drive the wind-shielding structure with the streamlined wrapping plate 1 as the main body to rotate a certain angle relative to the lifting plate 1006, ensuring that the direction facing the first wrapping plate 101 is the direction of the incoming wind, thereby adjusting the direction of the wind-shielding structure according to the wind direction, which is conducive to achieving a better wind-shielding effect.
