Abstract

The application discloses a ship outer plate protection device and a ship. The ship outer plate protection device comprises a flow guide mechanism, a spraying mechanism and a baffle. The flow guide mechanism comprises an inclined flow guide plate. The higher end of the flow guide plate is closer to the inside of the ship than the lower end. The lower end of the flow guide plate is above the outer plate of the ship and does not exceed the outer wall of the outer plate. The spraying mechanism is arranged above the flow guide plate. The baffle is rotationally connected to the flow guide mechanism through a hinge structure. The first end of the baffle is above the flow guide plate. The second end of the baffle extends to the outer wall of the outer plate. There is a gap between the second end of the baffle and the outer plate, which forms a water curtain. When the baffle rotates away from the outer plate, the second end of the baffle can be moved above the flow guide plate. The baffle can be turned over, so that the ship outer plate protection device does not protrude from the outer wall of the outer plate, thereby reducing the risk of collision during the ship running.

Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a marine hull protection device and a ship. Background Technology

[0002] More and more ships are using LNG (liquefied natural gas) as fuel. During the LNG refueling process, if a leak occurs and the sump overflows, the LNG will flow overboard. If the ship is rocking or there is wind, the LNG will fall onto the ship's outer plating. Since the temperature of LNG is more than -160 degrees Celsius, the ship's outer plating will freeze and break, causing serious accidents. Therefore, it is very necessary to protect the ship's outer plating at the refueling station location.

[0003] Existing ships have water curtain generating devices fixed above the ship's outer hull. When the ship's outer hull needs protection, the liquid sprayed by the water curtain generating device can flow down the ship's outer hull to form a water curtain, thereby protecting the ship's outer hull. However, because part of the structure of the water curtain generating device is set beyond the ship's outer hull, it indirectly increases the width of the ship. With this setting, the water curtain generating device is easily damaged by collisions during the operation of the ship. Summary of the Invention

[0004] One objective of this invention is to provide a ship outer plating protection device and a ship that can solve the technical problem that existing water curtain generating devices are easily damaged by collisions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ship's outer plating protection device includes a flow guiding mechanism, a spraying mechanism, and a baffle. The flow guiding mechanism includes an inclined flow guiding plate. The higher end of the flow guiding plate is closer to the interior of the ship than its lower end, and the lower end of the flow guiding plate is located above the ship's outer plating but does not extend beyond the outer wall of the ship's outer plating. The spraying mechanism is located above the flow guiding plate. The baffle is rotatably connected to the flow guiding mechanism via a hinge structure. The first end of the baffle is located above the flow guiding plate, and the second end of the baffle extends to the outer wall of the ship's outer plating, with a gap between the second end of the baffle and the ship's outer plating to allow liquid to form a water curtain. When the baffle rotates in a direction away from the ship's outer plating, the second end of the baffle can move above the flow guiding plate.

[0007] Optionally, the baffle is an arc-shaped plate or a folded plate.

[0008] Optionally, the baffle is a folded plate, and the baffle includes a first connecting plate, a second connecting plate and a third connecting plate connected in sequence; the included angle between the first connecting plate and the second connecting plate and the included angle between the second connecting plate and the third connecting plate are both obtuse angles, and the end of the third connecting plate away from the second connecting plate extends in a direction close to the outer plate of the ship.

[0009] Optionally, the flow guiding mechanism further includes a top plate and two side plates; the top plate is located at the higher end of the flow guiding plate, and the two side plates are respectively located on both sides of the flow guiding plate.

[0010] Optionally, the hinge structure includes a first component and a second component; the first component includes a first connector and a second connector, the first end of the first connector is fixedly connected to the side plate and the flow guiding mechanism, the first end of the second connector is fixedly connected to the baffle, and the second end of the first connector is rotatably connected to the second end of the second connector; the second component includes a third connector and a fourth connector, the first end of the third connector is rotatably connected to the outer wall of the side plate, the first end of the fourth connector is fixedly connected to the baffle, and the second end of the third connector is rotatably connected to the second end of the fourth connector; the length of the third connector is greater than the length of the fourth connector.

[0011] Optionally, a reinforcing rib is connected between the two side plates, and the reinforcing rib is connected to the back of the guide plate.

[0012] Optionally, the spraying mechanism includes a nozzle, wherein the angle between the spraying direction of the nozzle and the guide plate is smaller than the angle between the guide plate and the vertical line.

[0013] Optionally, it also includes a base, the base including a height adjustment mechanism, and the flow guiding mechanism is mounted on the base.

[0014] Optionally, the height adjustment mechanism includes an upper support, a lower support, and a support plate; both the upper support and the lower support are rectangular tubular structures, the upper support is disposed inside the lower support, and the outer peripheral wall of the upper support is in contact with the inner peripheral wall of the lower support; both sides of the lower support are provided with adjustment holes corresponding to the support plate; there are multiple adjustment holes, which are arranged sequentially along the height direction.

[0015] The beneficial effects of this invention are as follows: During operation, the spraying mechanism sprays liquid onto the guide plate. The liquid can flow along the inclined guide plate towards the outer wall of the ship's outer hull. During the liquid flow, it is blocked and limited by the baffle, so that the liquid can form a water curtain that flows evenly down the outer wall of the ship's outer hull between the second end of the baffle and the outer hull. This effectively protects the ship's outer hull from low-temperature damage during LNG refueling. Moreover, the baffle is rotatably connected to the guide structure through a hinge structure. When idle, the baffle can be rotated away from the ship's outer hull, so that the second end of the baffle can be moved above the guide plate. The lower end of the guide plate does not extend beyond the outer wall of the ship's outer hull. When no LNG leakage occurs, the flip-up design of the baffle ensures that the ship's outer hull protection device is not exposed on the outer wall of the ship's outer hull, which helps to reduce the risk of the ship's outer hull protection device being collided with during ship navigation. This effectively solves the technical problem that existing water curtain generating devices are easily damaged by collisions.

[0016] The present invention also provides a ship, including a ship outer plating and the aforementioned ship outer plating protection device, which can also reduce the risk of the ship outer plating protection device being collided during the ship's operation, thereby solving the technical problem that existing water curtain generating devices are easily damaged by collisions.

Detailed Implementation

[0028] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] More and more ships are using LNG (liquefied natural gas) as fuel. During the LNG refueling process, if a leak occurs and the sump overflows, the LNG will flow overboard. If the ship is rocking or there is wind, the LNG will fall onto the ship's outer plating. Since the temperature of LNG is more than -160 degrees Celsius, the ship's outer plating will freeze and break, causing serious accidents. Therefore, it is very necessary to protect the ship's outer plating at the refueling station location.

[0032] Existing ships have water curtain generating devices fixed above the ship's outer hull. When the ship's outer hull needs protection, the liquid sprayed by the water curtain generating device can flow down the ship's outer hull to form a water curtain, thereby protecting the ship's outer hull. However, because part of the structure of the water curtain generating device is set beyond the ship's outer hull, it indirectly increases the width of the ship. With this setting, the water curtain generating device is easily damaged by collisions during the operation of the ship.

[0033] In addition, this invention also found that some other existing ships weld water-blocking flat irons to form a water channel on the side deck. A horizontal slit is opened on the flat iron near the side. After the water channel is filled with water, it overflows from the slit to form a water curtain, thereby protecting the ship's outer plating. However, due to the uncertain floating state of the ship, it is difficult to keep the slit at the same height at the bow and stern, resulting in an uneven overflow of water curtain. Moreover, the water curtain formed is generally thrown outward, resulting in poor protection of the ship's outer plating. Furthermore, since many ships are equipped with side rails or oil-blocking flat irons, it is difficult to weld the channel structure onto the deck.

[0034] Please see Figures 1-9This invention provides a ship outer plating protection device, including a flow guiding mechanism 100, a spraying mechanism 200, and a baffle 300. The flow guiding mechanism 100 includes an inclined flow guiding plate 110. The higher end of the flow guiding plate 110 is closer to the interior of the ship than its lower end, and the lower end of the flow guiding plate 110 is located above the ship outer plating 600 and does not extend beyond the outer wall of the ship outer plating 600. The spraying mechanism 200 is located above the flow guiding plate 110. The baffle 300 is rotatably connected to the flow guiding mechanism 100 via a hinge structure 400. The first end of the baffle 300 is located above the flow guiding plate 110, and the second end of the baffle 300 extends to the outer wall of the ship outer plating 600. A gap is formed between the second end of the baffle 300 and the ship outer plating 600 to allow liquid to form a water curtain. When the baffle 300 rotates in a direction away from the ship outer plating 600, the second end of the baffle 300 can move above the flow guiding plate 110.

[0035] It should be noted that the spraying mechanism 200 is located on the side near the higher end of the guide plate 110, and is used to spray liquid onto the guide plate 110; the lower end of the guide plate 110 can be located between the inner wall and the outer wall of the ship's outer plate 600, and the lower end of the guide plate 110 is located near the top of the ship's outer plate 600, so that the liquid sprayed by the spraying mechanism 200 can flow along the guide plate 110 to the outer wall of the ship's outer plate 600; the hinge structure 400 is a mechanical structure used to connect the guide mechanism 100 and the baffle 300 and allow relative rotation between the two; when the baffle 300 rotates in a direction away from the ship's outer plate 600, the second end of the baffle 300 can move above the guide plate 110, at which time the entire baffle 300 is located above the guide plate 110.

[0036] The present invention has the following effects: (1) During operation, the spraying mechanism 200 sprays liquid from the guide plate 110. The liquid can flow along the inclined guide plate 110 to the outer wall of the ship's outer plate 600. During the flow of the liquid, it will be blocked and limited by the baffle 300, so that the liquid can form a water curtain that flows evenly down the outer wall of the ship's outer plate 600 between the second end of the baffle 300 and the ship's outer plate 600, thereby achieving the effect of effectively protecting the ship's outer plate 600 from low temperature damage during LNG refueling; (2) The baffle 300 is connected to the guide structure through the hinge structure 400. The rotating connection allows the baffle 300 to be rotated away from the ship's outer plating 600 when idle, so that the second end of the baffle 300 can be moved above the guide plate 110, and the lower end of the guide plate 110 does not extend beyond the outer wall of the ship's outer plating 600. When no LNG leakage occurs, the flip-up design of the baffle 300 ensures that the ship's outer plating protection device is not exposed on the outer wall of the ship's outer plating 600, which helps to reduce the risk of collision to the ship's outer plating protection device during ship navigation and effectively solves the technical problem that existing water curtain generating devices are easily damaged by collisions.

[0037] In one embodiment, the baffle 300 is an arc-shaped plate or a folded plate. Whether the baffle 300 is an arc-shaped plate or a folded plate, it can surround the lower end of the guide plate 110, thereby blocking and guiding the liquid sprayed from the lower end of the guide plate 110. This not only prevents the liquid on the guide plate 110 from being thrown directly overboard, but also allows the liquid to flow more concentratedly to the outer wall of the ship's outer plating 600. This helps guide the liquid to the gap between the second end of the baffle 300 and the ship's outer plating 600, so as to form a relatively uniform water curtain on the outer wall of the ship's outer plating 600, which has a good protective effect on the ship's outer plating 600.

[0038] As an optional implementation, please refer to Figure 3 and Figure 4 The baffle 300 is a folded plate, comprising a first connecting plate 310, a second connecting plate 320, and a third connecting plate 330 connected in sequence. The included angles between the first connecting plate 310 and the second connecting plate 320, and between the second connecting plate 320 and the third connecting plate 330, are both obtuse angles. The end of the third connecting plate 330 away from the second connecting plate 320 extends in a direction close to the outer plating 600 of the ship. The folded plate, composed of the first connecting plate 310, the second connecting plate 320, and the third connecting plate 330, effectively surrounds the lower end of the guide plate 110. As the distance between the baffle 300 and the outer plating 600 gradually decreases, the flow velocity of the liquid closer to the gap between the baffle 300 and the outer plating 600 increases, which is beneficial for guiding the liquid through the gap to form a stable and effective water curtain. Moreover, since the included angles between the first connecting plate 310 and the second connecting plate 320 and between the second connecting plate 320 and the third connecting plate 330 are both obtuse angles, the lateral span of the entire baffle 300 can be minimized as much as possible, which helps to reduce the risk of the baffle 300 being collided with when protecting the outer plate 600 of the ship.

[0039] Please see Figures 1-4 The flow guiding mechanism 100 also includes a top plate 120 and two side plates 130; the top plate 120 is located at the higher end of the flow guiding plate 110, and the two side plates 130 are respectively located on both sides of the flow guiding plate 110. The top of the top plate 120 and the top of the two side plates 130 are both higher than the flow guiding plate 110. The arrangement of the top plate 120 and the two side plates 130 can restrict the water flow, which helps to prevent liquid from splashing into the hull and to the sides of the flow guiding plate 110, and ensures that the liquid can flow normally along the inclined direction of the flow guiding plate 110 to the outer wall of the ship's outer plating 600.

[0040] In one embodiment, please refer to Figure 3 and Figure 4The lower end of the deflector 110 is flush with the outer wall of the ship's outer plating 600, away from the interior wall of the ship. The side plate 130 is flush with the outer wall of the ship's outer plating 600, away from the interior wall of the ship. The lower end of the deflector 110 is positioned close to the top of the ship's outer plating 600. This arrangement allows the liquid to be guided onto the ship's outer plating 600 as smoothly and with minimal loss as possible without increasing the width of the ship.

[0041] Please continue reading. Figure 3 and Figure 4 The hinge structure 400 includes a first component 410 and a second component 420. The first component 410 includes a first connector 411 and a second connector 412. The first end of the first connector 411 is fixedly connected to the side plate 130 and the flow guiding mechanism 100. The first end of the second connector 412 is fixedly connected to the baffle 300. The second end of the first connector 411 is rotatably connected to the second end of the second connector 412. The second component 420 includes a third connector 421 and a fourth connector 422. The first end of the third connector 421 is rotatably connected to the outer wall of the side plate 130. The first end of the fourth connector 422 is fixedly connected to the baffle 300. The second end of the third connector 421 is rotatably connected to the second end of the fourth connector 422. The length of the third connector 421 is greater than the length of the fourth connector 422. When the baffle 300 is flipped, a force is applied to the second end of the baffle 300, and the second connecting member 412 and the fourth connecting member 422, which are fixedly connected to the baffle 300, will also move accordingly. The second connecting member 412 will rotate around the axis between the first connecting member 411 and the second connecting member 412, while the fourth connecting member 422, while rotating around the axis between the third connecting member 421 and the fourth connecting member 422, will also drive the third connecting member 421 to rotate around the axis between the third connecting member 421 and the outer wall of the side plate 130. The simultaneous rotation of the shaft, the longer third connector 421, and the shorter fourth connector 422 allows the second end of the baffle 300 to rotate within a wide range of angles. This facilitates the second end of the baffle 300 to rotate from the outer wall of the ship's outer plating 600 to above the guide plate 110, so that the baffle 300 can be released during operation to guide liquid to form a water curtain on the outer wall of the ship's outer plating 600. When not in use, the baffle 300 can be retracted into the hull, without affecting the ship's width and less susceptible to damage from collisions.

[0042] It should be noted that there are two sets of hinge structures 400, which are distributed on both sides of the baffle 300 respectively. The two sets of hinge structures 400 together provide support for the baffle 300. The second connector 412 can be connected and fixed to the part of the side plate 130 that is higher than the guide plate 110. When the part of the side plate 130 that is higher than the guide plate 110 has a beveled edge parallel to the guide plate 110, the second connector 412 can be fixedly connected to the beveled edge of the side plate 130.

[0043] In one embodiment, please refer to Figures 1-6 The first connecting member 411 and the second connecting member 412, the third connecting member 421 and the fourth connecting member 422, and the third connecting member 421 and the outer wall of the side plate 130 are all rotatably connected by bolts 430. The bolts 430 are equipped with nuts. When the baffle 300 needs to be flipped or the gap between the second end of the baffle 300 and the outer plate of the ship needs to be adjusted, the nuts can be loosened appropriately to flip the baffle 300 or adjust the gap between the second end of the baffle 300 and the outer plate of the ship to meet the adjustment requirements of the baffle 300 in different working environments. When the device needs to be maintained, the bolts 430 and nuts can be removed to disassemble the entire baffle 300 for subsequent maintenance or replacement. In addition, based on the hinge structure 400 which enables the baffle 300 to be flipped, the angle of the baffle 300 can also be locked by the bolt 430. Both the hinge structure 400 and the bolt 430 are built-in structures of the protective device, making the entire protective device a steel outfitting component on the ship. Moreover, the hinge structure 400 integrated inside the protective device can achieve the flipping of the baffle 300 without the assistance of external structures or equipment (such as slings or pulley blocks), which provides better flexibility in installation and use and helps to expand the application range of the protective device.

[0044] In another embodiment, the ship's outer plating protection device also includes a push-pull mechanism connected to the baffle 300 or the hinge structure 400. For example, the push-pull mechanism can be installed on the side plate 130 and connected to the third connector 421. The push-pull mechanism can push the baffle 300 to rotate, thereby controlling the baffle 300 to automatically flip, which helps to reduce manual operation and thus reduce the labor intensity of the crew.

[0045] As an optional implementation, please refer to Figure 3 and Figure 4The baffle 300 includes a first connecting plate 310, a second connecting plate 320, and a third connecting plate 330 connected in sequence. The included angles between the first connecting plate 310 and the second connecting plate 320, and between the second connecting plate 320 and the third connecting plate 330, are both obtuse angles. The end of the third connecting plate 330 away from the second connecting plate 320 extends in a direction close to the outer plate 600 of the ship. The end of the first connecting plate 310 away from the second connecting member 412 is provided with a fourth connecting plate 340. The fourth connecting plate 340 facilitates the connection and fixation of the first connecting plate 310 and the second connecting member 412. The side plate 130 is provided with a bevel parallel to the guide plate 110. The first end of the second connecting member 412 is connected to the bevel of the side plate 130. The first end of the fourth connecting member 422 is fixedly connected to the side of the third connecting plate 330 facing the outer plate 600 of the ship. The first end of the third connecting member 421 is rotatably connected to the outer wall of the side plate 130. The above connection method can ensure that the baffle 300 has enough space to rotate, and at the same time, the baffle 300 can be as close as possible to the guide plate 110 or the outer plate of the ship when it rotates, thereby reducing the space occupied by the whole device and helping to reduce the risk of the device being collided with.

[0046] Please see Figures 2-4 A reinforcing rib 140 is connected between the two side plates 130, and the reinforcing rib 140 is connected to the back of the guide plate 110. The reinforcing rib 140 can strengthen the connection between the side plate 130 and the guide plate 110, and can increase the support area of ​​the guide plate 110, which is beneficial to improving the stability of the guide plate 110.

[0047] As an optional implementation, the reinforcing rib 140 includes horizontally and vertically arranged reinforcing ribs 140, which can further strengthen the connection strength between the side plate 130 and the guide plate 110 from multiple directions, thereby ensuring the stability of the guide plate 110.

[0048] In one embodiment, the spraying mechanism 200 includes a nozzle 220, the angle between the spraying direction of the nozzle 220 and the guide plate 110 being smaller than the angle between the guide plate 110 and the vertical line. See also... Figure 7Line m is a vertical line, line n is the vertical line of guide plate 110, angle α is the angle between the spray direction of nozzle 220 and guide plate 110, angle β is the angle between the vertical line and guide plate 110, ray OA is the splash direction of the liquid sprayed by nozzle 220 on guide plate 110, and ray OB is the splash direction of the liquid sprayed by nozzle 220 along the vertical line on guide plate 110. Obviously, when the liquid spray speed is the same, under the influence of gravity, the splash height of the liquid splashed along ray OA will be smaller than that of the liquid splashed along ray OA. Therefore, by setting the angle between the spray direction of the nozzle 220 and the guide plate 110 to be smaller than the angle between the guide plate 110 and the vertical line, the splash height of the liquid sprayed by the nozzle 220 on the guide plate 110 can be reduced, making it less likely for the liquid to splash out of the guide mechanism 100. Combined with the setting of the side plate 130, the top plate 120 and the baffle 300, the liquid sprayed by the nozzle 220 can be effectively prevented from splashing out of the guide mechanism 100, thereby achieving the effect of reducing liquid loss.

[0049] Please see Figure 1 The sprinkler system 200 also includes a sprinkler pipe 210, which is fixedly installed above the flow guide mechanism 100. The sprinkler pipe 210 is supplied with water by the ship's fire protection system. Multiple nozzles 220 are evenly distributed in the area above the flow guide plate 110 of the sprinkler pipe 210, so that the water supply can be dispersed and sprayed into the flow guide plate 110, which prepares for the formation of a uniform water curtain. The flow rate of the water curtain can be controlled by adjusting the water inlet of the sprinkler pipe 210 through the flow valve of the water supply system. During LNG refueling, it can effectively protect the ship's outer plate 600 from low-temperature damage. Compared to the existing solution that forms a protective water curtain for the ship's outer plating 600 by overflowing water through the gaps in the fixed water tank, the embodiment of the present invention uses a spraying mechanism 200 with multiple evenly distributed nozzles 220 for spraying. The ship's buoyancy does not affect the spraying direction of the nozzles 220 onto the guide plate 110, so the ship's buoyancy has little impact on the formation of the water curtain, and the generated water curtain is relatively uniform. This can effectively improve the problem that due to the uncertainty of the ship's buoyancy, it is difficult to keep the gaps in the water tank at the same height at both ends, resulting in uneven overflow of water curtain and poor protection effect on the ship's outer plating.

[0050] Furthermore, compared to the scheme of directly installing the spray mechanism 200 at the bottom of the baffle 300, this embodiment of the invention installs the spray mechanism 200 above the flow guiding mechanism 100. On the one hand, during installation, there is no need to consider the issue of needing sufficient installation space for the spray mechanism 200 between the baffle 300 and the flow guiding mechanism 100, thereby reducing the installation difficulty of the spray mechanism 200. At the same time, it can avoid the trouble of the water supply pipe connected to the spray pipe 210 moving as the baffle 300 is flipped. On the other hand, when the size of the gap between the baffle 300 and the ship's outer plate 600 is adjusted, the placement angle of the baffle 300 will change, thereby causing the spray mechanism 200 to move accordingly. The spray angle of the nozzle 220 of the spray mechanism 200 toward the ship's outer plate 600 will also change accordingly. The spray angle of the nozzle 220 installed on the baffle 300 will directly affect the water curtain generation effect, thereby affecting the protective effect of the protective device on the ship's outer plate 600.

[0051] Please see Figure 3 and Figure 4 It also includes a base 500, which includes a height adjustment mechanism, and a flow guiding mechanism 100 is mounted on the base 500. After determining the installation height and position of the flow guiding mechanism 100 according to the hull form, the flow guiding mechanism 100 and the baffle 300 can be installed at the required height using the height adjustment structure of the base 500. This allows the entire ship outer plating protection device to be made into an independent iron outfitting component, suitable for installation on ships with various hull forms, and can form an effective water curtain to protect the ship outer plating 600. Moreover, the overall structure of the device occupies relatively little space on the hull, which is beneficial for the overall layout of the LNG refueling station and hose brackets.

[0052] Please see Figure 8 and Figure 9 The height adjustment mechanism includes an upper support 510, a lower support 520, and a support plate 530. Both the upper support 510 and the lower support 520 are rectangular tubular structures. The upper support 510 is located inside the lower support 520, and the outer peripheral wall of the upper support 510 contacts and abuts against the inner peripheral wall of the lower support 520. The lower support 520 has adjustment holes 521 on both sides corresponding to the support plate 530. There are multiple adjustment holes 521, which are arranged sequentially along the height direction. That is, the upper support member 510 can move up and down within the lower support member 520. The upper support member 510 is used to connect with the flow guiding mechanism 100. The lower support member 520 can be provided with a base plate that is fixed to the internal structure of the ship. The length of the support plate 530 is greater than the width of both sides of the lower support member 520. The support plate 530 is snapped into the lower support member 520 through the snap-in adjustment hole 521. The support plate 530 supports the upper support member 510. The upper support member 510 can be installed at a suitable height according to actual needs.

[0053] During installation, on the one hand, after determining the installation height and position of the flow guiding mechanism 100 according to the side profile, the upper support 510 moves up and down within the lower support 520 to the required height. Then, the adjustment holes 521 located on both sides of the lower support 520 and corresponding to the bottom of the upper support 510 are checked. The corresponding adjustment holes 521 can be marked, and then the support plate 530 is inserted into the marked adjustment holes 521 on both sides. The installed support plate 530 can provide stable support for the upper support 510, achieving the effect of installing the upper support 510 at the corresponding height. This realizes the installation of the flow guiding mechanism 100 and the baffle 300 at the required height, meeting the needs of installing the ship's outer plating protection device at different heights, effectively expanding the scope of application of the device; on the other hand, the upper... Both the upper support 510 and the lower support 520 adopt a rectangular tubular structure. The outer peripheral wall of the upper support 510 and the inner peripheral wall of the lower support 520 are in contact and abut against each other. This ensures that the upper support 510 can move up and down within the lower support 520, while also limiting the upper support 510 at various angles in the horizontal direction. This effectively prevents the upper support 510 from swaying left and right, ensuring the stability of the upper support 510 in supporting the flow guiding mechanism 100. This is beneficial to improving the stability and impact resistance of the flow guiding mechanism 100, so that the flow guiding plate 110 and the baffle 300 can stably guide the water flow to form a water curtain to protect the outer plate 600 of the ship. Moreover, using a rectangular tubular structure for the upper support 510 and the lower support 520 can effectively reduce the weight of the device and facilitate movement and disassembly.

[0054] As an optional implementation, the side plate 130 of the flow guiding mechanism 100 is fixedly connected to the upper support member 510 by a detachable fastener. The side wall of the upper support member 510 may have a plurality of connecting holes 511 arranged along the height direction. The connecting holes 511 allow the fastener to fix the side plate 130 to the upper support member 510, and the side plate 130 can be installed on the connecting holes 511 at the corresponding heights of the upper support member 510 as needed. The distance between two adjacent connecting holes 511 is smaller than the distance between two adjacent adjusting holes 521. This arrangement allows for a wide range of height adjustment of the flow guiding mechanism 100 through the adjusting holes 521, and a small range of height adjustment of the flow guiding mechanism 100 through the connecting holes 511, thereby facilitating the accurate installation of the flow guiding mechanism 100 at the required height.

[0055] It should be noted that during installation, the height of the upper support member 510 within the lower support member 520 must be at least 1 / 3 of its own height. This arrangement ensures that the upper support member 510 can be stably installed within the lower support member 520. Furthermore, when the height of the upper support member 510 within the lower support member 520 is less than 1 / 2 of its own height, a reinforcing kit 540 can be provided at the top of the lower support member 520 as needed. The reinforcing kit 540 can be simultaneously fitted onto the outer periphery of both the upper support member 510 and the lower support member 520. The top of the reinforcing kit 540 has a connection point with the upper support member 510. The first port matches the outer peripheral wall, and the bottom end of the reinforcing kit 540 is provided with a second port that matches the outer peripheral wall of the lower support 520. The first port and the second port are interconnected through the inner cavity of the reinforcing kit 540. The reinforcing kit 540 can further reinforce the upper support 510, which helps to ensure the stability of the flow guiding mechanism 100. The flow guiding mechanism 100 and the baffle 300 can be made of lightweight materials, making the overall structure simple, lightweight, and easy to install and disassemble. The number of bases 500 is not limited to one set. Two or more sets of bases 500 can be set according to actual needs to provide stable support for the flow guiding mechanism 100.

[0056] In one embodiment, please refer to Figure 8 and Figure 9 The tray 530 is provided with a protrusion 531 that matches the inner peripheral wall of the upper support member 510. The tray 530, including the height of the protrusion 531, can pass through the adjustment hole 521. The two sides of the tray 530 can be provided with gripping parts 532 for easy holding. The protrusion 531, together with the lower support member 520, can limit and fix the bottom end of the upper support member 510, which helps to prevent the upper support member 510 from shaking. This ensures that the upper support member 510 can be stably installed on the tray 530, thereby ensuring the stability of the flow guiding mechanism 100 installation and allowing the flow guiding plate 110 and the baffle 300 to operate in a stable environment.

[0057] This invention also provides a ship, including a ship outer plating 600 and the aforementioned ship outer plating protection device, which can also reduce the risk of the ship outer plating protection device being collided with during ship navigation, thereby solving the technical problem that existing water curtain generating devices are easily damaged by collisions.
