Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to an external support structure for the salvage and repair of sunken ships. Background Technology

[0002] Underwater archaeology in my country is currently in its nascent stage. With the continuous development of archaeological exploration, more and more ancient shipwrecks are being discovered in waterways. Shipwreck salvage technology provides important support for marine archaeology, and more and more ship hulls will be excavated as a whole in the future.

[0003] The post-salvage handling is equally important, involving multiple aspects such as environmental cleanup, artifact preservation, structural reinforcement, and exhibition and research. The organic combination of these aspects ensures the safety and maximizes the value of the shipwreck and its artifacts.

[0004] There are some challenges in the archaeological process. For example, the ancient ship may have been damaged to some extent when it sank, and the hull is severely corroded. After being salvaged, the ancient ship is very likely to be further damaged during the long-term cleaning and maintenance process. If not handled carefully, the fragile hull may fall apart, causing incalculable losses.

[0005] Therefore, it is necessary to develop a new type of external support structure for shipwreck salvage and repair in order to improve some of the problems mentioned above in related technologies. Utility Model Content

[0006] The purpose of this invention is to provide an external support structure for the salvage and repair of sunken ships, which can be adjusted in a timely manner as the cleaning and maintenance progresses after the hull and its attachments are salvaged, so as to reduce further damage to the hull.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] The external support structure for shipwreck salvage and repair provided by this utility model includes: a working platform, a base, a support part, and a connecting part; the working platform is used to form a working space for placing the salvaged hull and its attachments; the base is disposed on the inner wall surface of the working platform; the support part is used to support the hull; the connecting part connects the base and the support part; wherein, the working space provided by the working platform is lower than the surrounding height, and the connecting part extends to the bottom of the working space, so that the support part supports the hull at different heights above the bottom.

[0009] Furthermore, the connecting part is a connecting rod system structure, which is formed by spaced-apart rods, the arrangement direction of the rods pointing towards the bottom of the working space, and the support part and the base are disposed opposite to each other at the horizontal ends of the connecting rod system structure.

[0010] Furthermore, at least three layers of the rods are arranged at intervals to form the connecting rod system structure, with the first and second layers of rods connecting to the base, and the third layer of rods connecting to the inner wall surface of the work platform.

[0011] Furthermore, the connecting part is a column member, which is disposed on the surface of the base, and the extending direction of the column member points to the bottom of the working space.

[0012] Furthermore, a diagonal brace is provided between the connecting part and the inner wall surface of the working platform.

[0013] Furthermore, the support includes a cantilever structure and a crossbeam. The length of the bottom of the cantilever structure is greater than its top length. The crossbeam is positioned at different heights on the free end of the cantilever structure to support the hull at different heights from the bottom.

[0014] Furthermore, the support also includes a longitudinal beam, the crossbeam is an I-beam, the two ends of the longitudinal beam are connected to the two side flanges of the crossbeam, and the longitudinal beam is located at the connection between the crossbeam and the supporting cantilever structure.

[0015] Furthermore, the aforementioned beams are interconnected to form a single unit.

[0016] Furthermore, a moving device is provided between the crossbeam and the supporting cantilever structure to move the crossbeam closer to or away from the free end of the supporting cantilever structure.

[0017] Furthermore, the members supporting the cantilever structure are connected by fasteners.

[0018] Furthermore, the base is located at the top of the work space and extends through the wall of the work platform.

[0019] Furthermore, the inner contour surface of the work platform is arc-shaped.

[0020] Furthermore, the support, the connecting part, and the base are symmetrically arranged on the inner wall surfaces of both sides of the working platform.

[0021] Compared with the prior art, the external support structure for shipwreck salvage and repair provided by this utility model has the following beneficial effects:

[0022] 1. The external support structure in this utility model forms a sunken working space lower than the surrounding area through the working platform. After the hull and its attachments are salvaged as a whole, they are placed in the working space. For example, the hull and the soil covering the hull are placed in the working space as a whole. As the attachments covering the hull are gradually cleared from top to bottom in the working space, the hull will gradually lose the support of the attachments and its stress condition will change. At this time, the connecting parts continuously extend to the bottom of the working space, so that the support parts set on the connecting parts replace the attachments and gradually form multiple supports from top to bottom at different heights from the bottom of the working platform. This allows the support structure to be adjusted in a timely manner as the cleaning and maintenance progresses, so as to reduce further damage to the hull. In addition, since the hull and its attachments are salvaged as a whole and placed in the working platform, the attitude of the hull on the seabed before salvage is consistent with the attitude of the hull after salvage and placement in the working space, which also avoids further damage that may be caused by attitude changes.

[0023] 2. This utility model uses a rod-like structure to form the connecting part, which provides high spatial flexibility when the connecting part forms a multi-layered structure. As the attached material is cleaned, the depth of the connecting part extending towards the bottom of the working space can be flexibly adjusted from top to bottom as needed. This flexibility ensures effective support for the hull at different heights above the bottom. Furthermore, the rod-like structure of the connecting part can effectively resist various loads, which helps to increase the overall load-bearing capacity of the external support structure.

[0024] 3. This utility model forms a stable and reliable base by setting the base at the top of the work space and penetrating the wall of the work platform. At least three layers of rods are arranged at intervals to form a rod system structure. The first and second layers of rods connect to the base, which improves the stability and load-bearing capacity of the external support structure. The third layer of rods connects to the inner wall surface of the work platform. When the number of connection layers increases, it takes into account both structural stability and flexibility to extend to the bottom of the work space.

[0025] 4. This utility model further enhances the structural stability of the connecting part by providing diagonal bracing between the connecting part and the inner wall surface of the working platform.

[0026] 5. This utility model uses a method where the length of the bottom of the cantilever structure is greater than the length of its top to make its free end inclined, and sets crossbeams at different heights on the free end of the cantilever structure to form several inclined support layouts. Due to the characteristics of shipwrecks, the bottom of a shipwreck will generally be inclined to a certain extent. The inclined support layout can effectively disperse stress when the hull is supported by crossbeams, making the stress distribution more uniform, thereby reducing local stress concentration and thus reducing damage to the hull.

[0027] 6. This utility model connects the two ends of the longitudinal beam to the two side flanges of the transverse beam, so that the longitudinal beam is located at the connection between the transverse beam and the supporting cantilever structure, which helps to enhance the structural strength of the connection and improve the support stability of the hull.

[0028] 7. This utility model has a moving device between the crossbeam and the supporting cantilever structure, which moves the crossbeam closer to or away from the free end of the supporting cantilever structure. It can adjust the magnitude of the supporting force and the position of the supporting point according to the changes in the stress on the hull, which is beneficial to protecting the hull.

[0029] 8. This utility model uses fasteners to connect the supporting rods of the cantilever structure. The fasteners have outstanding convenience in installation and disassembly, which is conducive to the construction at any time according to the cleaning and maintenance progress of the hull, improving construction efficiency, reducing construction time, and allowing the supporting cantilever structure to extend to the bottom of the working space along with the connecting part.

[0030] 9. This utility model makes the inner contour surface of the working platform arc-shaped, matching the bottom arc shape of the arc-shaped shield tunnel when it excavates the hull and its attachments from the bottom of the water. When the hull and its attachments are placed in the working space of the working platform, it helps to keep the stress on the hull and its attachments unchanged.

[0031] 10. This utility model uses a support part, a connecting part and a base symmetrically arranged on the inner wall surface of both sides of the working platform, so that the hull can be evenly and symmetrically supported on both sides, which is beneficial to protecting the hull.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0039] Figure 1 This is a schematic diagram of the external support structure for shipwreck salvage and repair in an embodiment of this utility model.

[0040] This utility model embodiment provides an external support structure for shipwreck salvage and repair, such as Figure 1 As shown, the external support structure includes: a working platform 1, a base 2, a support part 4, and a connecting part 3; the working platform 1 is used to form a working space to place the salvaged hull 5 and its attached objects 6; the base 2 is disposed on the inner wall surface of the working platform 1; the support part 4 is used to support the hull 5; the connecting part 3 connects the base 2 and the support part 4; wherein, the working space provided by the working platform 1 is lower than the surrounding height, and the connecting part 3 extends to the bottom of the working space, so that the support part 4 supports the hull 5 at different heights from the bottom.

[0041] In some specific embodiments, such as Figure 1 As shown, the work platform 1 includes a pool-like structure, forming a work space that is lower than the surrounding height. The work platform 1 can be housed within a sunken building or a ground-level building; this invention does not impose any limitations on this.

[0042] In some specific embodiments, such as Figure 1 As shown, the base 101 of the work platform 1 is reinforced concrete, and a pool-shaped wall 102 is constructed on the base 101, forming a work space inside the wall 102.

[0043] In some specific embodiments, such as Figure 1 As shown, the inner contour surface of the work platform 1 is arc-shaped, that is, the cross-sectional shape of the wall 102 is arc-shaped.

[0044] Specifically, the arc-shaped inner contour surface can form a cylindrical working space or a hemispherical working space, and this utility model does not limit it in this way.

[0045] In some other specific embodiments, the wall 102 of the work platform 1 includes a vertically arranged wall 102 and a horizontally arranged wall 102 at the bottom to form a cuboid work space. The present invention does not limit the shape of the work space.

[0046] In some specific embodiments, such as Figure 1 As shown, the base 2 is mounted on the surface of the wall 102 by fasteners.

[0047] In some specific embodiments, the support part 4 abuts against the outer surface of the hull 5, and a flexible breathable pad is provided on the support part 4 to protect the position on the hull 5 that is abutted by the support part 4.

[0048] In some specific embodiments, such as Figure 1 As shown, the support part 4 is provided on the connecting part 3. As the connecting part 3 extends towards the bottom of the working space, the height of the connecting part 3 gradually increases, and the height of the support part 4 increases along with the connecting part 3, so that the connecting part 3 is provided with the support part 4 at each extension point, so as to support the hull 5 at different heights from the bottom.

[0049] In some specific embodiments, different heights from the bottom refer to different distances from the bottom of the workspace.

[0050] In some specific embodiments, the connecting portion 3 extends vertically downward.

[0051] In some other embodiments, the extension direction of the connecting part 3 can match the extension direction of the wall 102 of the work platform 1.

[0052] For example, the wall 102 is vertically arranged, and the extension direction of the connecting part 3 is vertically downward.

[0053] For example, the wall 102 is arranged in an arc shape, and the extension direction of the connecting part 3 can also extend along the arc direction.

[0054] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the connecting part 3 is a connecting rod system structure 301, which is formed by spaced rods. The arrangement direction of the rods points to the bottom of the working space. The support part 4 and the base 2 are arranged opposite each other at the horizontal ends of the connecting rod system structure 301.

[0055] Figure 3 This is a schematic diagram of a connecting rod system with two layers in the first type of embodiment.

[0056] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the base 2 is set at the top of the work space and penetrates the wall 102 of the work platform 1. At least two layers of rods are arranged at intervals to form a connecting rod structure 301. The first layer of rods and the second layer of rods connect the base 2.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, at least three layers of rods are arranged at intervals to form a connecting rod structure 301. The first and second layers of rods are connected to the base 2, and the third layer of rods is connected to the inner wall surface of the work platform 1.

[0058] Figure 4 This is a schematic diagram of a structure in the second type of embodiment where the connecting part is a column.

[0059] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, a diagonal brace 7013 is provided between the connecting part 3 and the inner wall surface of the working platform 1.

[0060] In some specific embodiments, such as Figure 3 As shown, the connecting rod structure 301 includes horizontal members 7011, diagonal braces 7013, and vertical members 7012. The first layer of horizontal members 7011 and the second layer of horizontal members 7011 constitute the first layer of the connecting rod structure 301. The two ends of the horizontal members 7011 are connected to the vertical members 7012 and the base 2, respectively. The two ends of the diagonal braces 7013 are connected to the end of the first layer of horizontal members 7011 away from the base 2 and the end of the second layer of horizontal members 7011 near the base 2.

[0061] In some specific embodiments, such as Figure 3 As shown, the second layer of horizontal members 7011 and the third layer of horizontal members 7011 form the second layer of the connecting rod structure 301. The two ends of the third layer of horizontal members 7011 are connected to the inner wall surface of the work platform 1 and the vertical member 7012, that is, the surface of the wall 102 of the work platform 1 and the vertical member 7012, respectively. The two ends of the diagonal brace 7013 are connected to the end of the second layer of horizontal members 7011 away from the base 2 and the end of the third layer of horizontal members 7011 near the inner wall surface of the work platform 1.

[0062] In some specific embodiments, such as Figure 3 As shown, the third layer horizontal members 7011 and the fourth layer horizontal members 7011 form the third layer of the connecting rod structure 301. The two ends of the fourth layer horizontal member 7011 are connected to the inner wall surface of the work platform 1 and the vertical member 7012, that is, the surface of the wall 102 of the work platform 1 and the vertical member 7012, respectively. The two ends of the diagonal brace 7013 are connected to the end of the third layer horizontal member 7011 away from the inner wall surface of the work platform 1 and the end of the fourth layer horizontal member 7011 close to the inner wall surface of the work platform 1.

[0063] In some specific embodiments, the vertical member 7012 can be formed by combining multiple members. The length of the vertical member 7012 formed by combining multiple members can be selected according to the distance between the two farthest horizontal members 7011. This utility model does not limit this.

[0064] In some specific embodiments, although the base 2 is named "base", the location of the base 2 is not limited to the bottom of the work space. It can be set at any height in the work space by fixing it to the inner wall surface of the work platform 1.

[0065] In some specific embodiments, the base 2 can be connected to the top of the wall 102 near the work platform 1 by pre-embedded parts, bolts and other fasteners.

[0066] In some specific embodiments, the base 2 can penetrate the wall 102 of the entire working platform 1 through tie rods or other means to obtain better connection strength. The present invention does not limit the specific connection method.

[0067] In some specific embodiments, the support 4 is disposed on the vertical rod 7012.

[0068] In some specific embodiments, the purpose of the connecting part 3 is to provide support for the support part 4 through the side of the work space. The inner wall surface of the work platform 1 is the lateral inner wall surface of the work platform 1. Generally, the connecting part 3 is formed by building it layer by layer from top to bottom, and the connecting part 3 does not provide support for the support part 4 through the bottom of the work space. Specifically, the horizontal members 7011 of the connecting rod structure 301 do not contact the bottom of the work space, and the ends of the vertical members 7012 of the connecting rod structure 301 also do not contact the bottom of the work space.

[0069] It should be noted that if the work space is rectangular, the side walls and bottom walls of the work platform 1 are clearly distinguishable, the base 2 is set on the side wall of the work platform 1, and the connecting part 3 is set on the base 2 and the side wall of the work platform 1.

[0070] It should be noted that when the inner contour of the work space is curved, the wall 102 of the work platform 1 is also curved, making it difficult to determine the boundary between the side and bottom of the work space. The bottom of the work space can be determined by taking one-fifth of the overall height of the work space as the boundary. Above this boundary is the side wall of the work platform wall 102, and below this boundary is the bottom surface of the work platform wall 102.

[0071] It should be noted that in extreme cases, such as when there are few attachments 6 on the hull 5 and the bottom of the hull 5 is close to the bottom of the work space, the connecting part 3 extends to a greater extent towards the bottom of the work space in order to provide support from below the hull 5. The bottom end of the connecting part 3 may be close to the bottom of the work space. In this case, if the bottom of the connecting part 3 inevitably has some contact with the bottom of the work space, or has some contact with the bottom of the work space due to engineering practice requirements, the existence of such contact should not exclude the technical solution from the scope of protection defined in this claim.

[0072] In other embodiments of this utility model, such as Figure 4 As shown, the connecting part 3 is a column 302, which is disposed on the surface of the base 2, and the extension direction of the column 302 points to the bottom of the working space.

[0073] In some specific embodiments, such as Figure 4 As shown, the column 302 is directly installed and fixed by connecting the side to the base 2. The end of the column 302 extends downward, and the two ends of at least one diagonal brace 7013 are connected to the side of the column 302 and the inner wall surface of the work platform 1.

[0074] In some specific embodiments, the support portion 4 connects to the side of the column member 302.

[0075] In some embodiments of this utility model, the support part 4, the connecting part 3 and the base 2 are symmetrically arranged on the inner wall surfaces of both sides of the working platform 1.

[0076] In some specific embodiments, the connecting part 3 is a connecting rod structure 301 and is symmetrically arranged on both sides.

[0077] In some specific embodiments, the connecting part 3 is a column 302 and is symmetrically arranged on both sides.

[0078] In other embodiments of this utility model, such as Figure 1 As shown, one side of the connecting part 3 is a connecting rod structure 301, and the other side is a column 302, with the two sides arranged asymmetrically.

[0079] Figure 2 for Figure 1 Enlarged structural diagram at point A in the middle.

[0080] In some embodiments of this utility model, such as Figure 2 As shown, the support part 4 includes a support cantilever structure 401 and a crossbeam 402. The length of the bottom of the support cantilever structure 401 is greater than the length of its top. The crossbeam 402 is set at different heights on the free end of the support cantilever structure 401 to support the hull 5 at different heights from the bottom.

[0081] In some specific embodiments, such as Figure 1 and Figure 2 As shown, the supporting cantilever structure 401 includes horizontal members 7011 and vertical members 7012. The length of each layer of horizontal members 7011 increases as it approaches the bottom of the working space. One end of each layer of horizontal members 7011 is connected to the connecting part 3, and the other end forms an inclined support layout, and a crossbeam 402 is provided on it.

[0082] In some specific embodiments, such as Figure 2 As shown, the crossbeam 402 is inclined in the horizontal direction to fit against the inclined surface of the hull 5.

[0083] In some specific embodiments, a crossbeam 402 is provided at the end of each layer of horizontal members 7011.

[0084] In some specific embodiments, the crossbeams 402 at the ends of each layer of horizontal members 7011 are connected end to end to form a single unit.

[0085] In some embodiments of this utility model, such as Figure 2 As shown, the support part 4 also includes a longitudinal beam 403 and a crossbeam 402 which is an I-beam. The two ends of the longitudinal beam 403 are connected to the two side flanges of the crossbeam 402. The longitudinal beam 403 is located at the connection between the crossbeam 402 and the supporting cantilever structure 401.

[0086] In some specific embodiments, the crossbeam 402 connects to the end of the horizontal member 7011 on the cantilever structure 401, and the two ends of the longitudinal beam 403 are connected to the two side flanges of the crossbeam 402.

[0087] In some specific embodiments, the longitudinal beam 403 connects to the end of the horizontal member 7011 on the cantilever structure 401, and the crossbeam 402 is disposed on the longitudinal beam 403.

[0088] In some specific embodiments, the crossbeam 402 or the longitudinal beam 403 is an I-beam.

[0089] In some specific embodiments, a flexible breathable pad is disposed on the crossbeam 402.

[0090] It should be noted that the component supporting the hull 5 is named "crossbeam". The term "cross" or "beam" in this name should not be construed as limiting the shape, length or orientation of the component. Any component that can provide support, regardless of its structure, should be within the scope of protection defined by the claims.

[0091] In some embodiments of this utility model, such as Figure 2 As shown, a moving device 404 is provided between the crossbeam 402 and the supporting cantilever structure 401, which is used to move the crossbeam 402 closer to or away from the free end of the supporting cantilever structure 401.

[0092] In some specific embodiments, the mobile device 404 uses a motor as a power source, and the output of the mobile device 404 is connected to the crossbeam 402, which drives the crossbeam 402 to move horizontally.

[0093] In some specific embodiments, the moving device 404 also includes a displacement sensor to detect the distance the crossbeam 402 has moved.

[0094] In some specific embodiments, the moving device 404 further includes a detection unit for detecting stress changes at various locations on the hull 5. The detection unit is electrically connected to the motor and automatically adjusts the movement of the crossbeam 402 according to the stress changes.

[0095] In some specific embodiments, the detection of stress changes at multiple locations on the hull 5 by the detection unit can be achieved in various ways, including setting strain gauges at multiple locations on the hull 5. These various specific methods are known to those skilled in the art, and therefore will not be described in detail here.

[0096] In some embodiments of this utility model, the rods supporting the cantilever structure 401 are connected by fasteners 405.

[0097] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0100] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
