Sea passage pipes are generally used to introduce cooling seawater or discharge wastewater. They are typically connected to the hull by welding.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] refer to Figure 1 As shown, current ship navigation systems incorporate flexible connectors into the navigation pipes to compensate for hull deformation at different drafts during navigation, thereby preventing breakage at the weld between the navigation pipe and the hull.

[0038] Currently, once flexible joints are installed, they are difficult to adjust. Especially as ships navigate at different drafts, the deformation of the hull varies significantly, leading to different displacement compensation requirements for the flexible joints. Furthermore, during navigation, environmental conditions and other limitations make it difficult to accurately measure the deformation of the flexible joints in real time. If displacement compensation exceeds acceptable limits, it could cause the pipeline to rupture, seriously affecting the safe operation of the ship.

[0039] Based on this, the present invention proposes a flexible nozzle adjustment system for ships that can ensure minimal deformation of the flexible nozzle at various drafts, effectively avoid the risk of displacement compensation exceeding tolerances of the flexible nozzle, and improve the safety and reliability of ship navigation.

[0040] The following is combined Figure 2 This invention describes a flexible, sea-accessible control system for ships. For example... Figure 2 As shown, in an embodiment of the present invention, the ship's sea passage flexible nozzle adjustment system includes: a sea passage pipe 10, a flexible nozzle 20 connected to the sea passage pipe 10, a plurality of supports 30 and a controller 40.

[0041] One end of each of the brackets 30 is connected to the support part of the hull, and the other end is connected to the sea passage pipe 10 or the flexible connector 20, for supporting the sea passage pipe 10 or the flexible connector 20;

[0042] The controller 40 is electrically connected to several of the brackets 30 and is used to control the height of each bracket 30 based on the current draft of the hull, so that the deformation of the flexible connector 20 meets the expected deformation. The height between the two ends of the bracket 30 is different at different height levels.

[0043] Here, the bracket 30 and controller 40 are key components of the ship's sea passage flexible nozzle adjustment system. One end of the bracket 30 is fixed to a support part of the hull, and the other end is connected to the sea passage pipe 10 or the flexible nozzle 20. The function of the bracket 30 is to support and secure the sea passage pipe 10 and the flexible nozzle 20, ensuring that they do not move or deform excessively.

[0044] Specifically, in this embodiment, the support 30 is a height-adjustable support. The controller 40 is electrically connected to all supports 30, and can receive information about the current draft of the hull, and calculate the height setting that each support 30 should be adjusted to based on this information. By controlling the height of the support 30, the controller 40 can ensure that the deformation of the flexible connector 20 meets expectations, thereby effectively avoiding the risk of the flexible connector exceeding tolerances.

[0045] The ship's flexible nozzle adjustment system first detects the ship's current draft. The controller 40, based on the detected draft and a preset algorithm or control strategy, determines the appropriate height setting for each support 30. The controller 40 sends adjustment commands to each support 30 via electrical signals, and the support 30 adjusts to the corresponding height setting accordingly. By flexibly adjusting the height of the support 30, the controller 40 can control the deformation of the flexible nozzle 20, keeping it within the expected deformation range.

[0046] Specifically, the sea passage pipeline 10 includes a first sea passage pipeline and a second sea passage pipeline respectively connected to both ends of the flexible connector 20, and at least one of the supports 30 is respectively provided on the flexible connector 20, the first sea passage pipeline and the second sea passage pipeline.

[0047] Here, the flexible nozzle 20 is located between the first and second sea passages and is used to absorb the hull deformation generated during navigation. The elastic deformation of the flexible nozzle 20 ensures the overall stability of the sea passages.

[0048] Support brackets 30 are installed on the flexible nozzle 20, the first sea passage pipe, and the second sea passage pipe to provide necessary support and stability. At least one support bracket is installed on each pipe to support and secure the sea passage pipe 10 and the flexible nozzle 20 through its height adjustment function, preventing them from being excessively deformed due to deformation of the hull.

[0049] Further reference Figure 2 As shown, in an embodiment of the present invention, the ship's sea-passing flexible nozzle adjustment system further includes: a server 50, which is communicatively connected to the controller;

[0050] The server 50 stores a database of the correspondence between preset draft and optimal height gear combination under different preset draft depths, so that the controller 40 can adjust the height gear of each of the supports 30 based on the current draft of the hull by using the database stored in the server 50.

[0051] The optimal height setting combination is a combination of several height settings of the bracket 30 that minimize the deformation of the flexible pipe at the preset draft depth.

[0052] Here, server 50 pre-stores a database that records the correspondence between the optimal height gear combination and the preset draft under different preset draft depths.

[0053] Specifically, the correspondence between the preset draft and the optimal height combination is obtained through ship mooring tests. In these tests, the ship's draft is adjusted one by one to each preset draft, such as L1, L2, L3, ..., L... m Then, for each preset draft, the optimal height setting combination with the minimum deformation of the flexible hose 20 was tested.

[0054] Furthermore, in an embodiment of the present invention, it includes: m supports 30, each of the supports 30 including n height levels, where m and n are both positive integers;

[0055] The optimal height combinations of several brackets 30 at each preset draft depth are obtained by the following method: for each preset draft depth, n is measured at that preset draft depth. m The flexible hose n under each height setting combination m One deformation amount;

[0056] Determine n at the preset draft depth m The height gear combination corresponding to the smallest deformation among the aforementioned deformation amounts is the optimal height gear combination under the preset draft.

[0057] Here, each bracket 30 includes n height settings, and m brackets 30 have n height settings. m In this embodiment, for each preset draft depth, n is measured using a combination of height settings. m Deformation of flexible hose 20 under different height settings Then the amount of deformation The combination of height settings corresponding to the minimum value is the optimal combination of height settings for this preset draft.

[0058] Furthermore, in an embodiment of the present invention, the controller 40 is also used to obtain the current draft of the hull, and when it is detected that there is a first preset draft in the database stored in the server 50 that is the same as the current draft, the controller adjusts the height of each of the supports based on the optimal height gear combination corresponding to the first preset draft.

[0059] The ship's flexible seakeeping maneuvering system first obtains the ship's current draft depth through sensors or other devices. After receiving the current draft depth, the controller 40 queries the database through communication with the server 50 to see if a first preset draft depth with the same current draft depth exists. After finding the corresponding first preset draft depth, the controller 40 sends adjustment commands to each support 30 through the communication protocol based on the optimal height gear combination stored at the first preset draft depth, so that they are adjusted to the corresponding height gear.

[0060] Furthermore, in an embodiment of the present invention, the controller 40 is also used to obtain the current draft of the hull, and when it is detected that there is no first preset draft that is the same as the current draft in the database stored in the server 50, the height of each of the supports is adjusted based on the optimal height gear combination corresponding to the second preset draft.

[0061] The second preset draft is the preset draft depth with the smallest depth difference from the current draft depth among a plurality of preset draft depths stored in the database of the server 50.

[0062] If the database does not contain a first preset draft that is the same as the current draft, the controller 40 will further search the database for the preset draft that has the smallest depth difference with the current draft, i.e., the second preset draft.

[0063] The controller 40 compares the differences between all preset draft depths in the database and the current draft depth, and selects the preset draft depth with the smallest difference as the second preset draft depth. Based on the optimal height gear combination corresponding to the found second preset draft depth, the controller 40 sends adjustment commands to each support to adjust them to the corresponding height gear.

[0064] Furthermore, in an embodiment of the present invention, it further includes: a draft measuring device, which communicates with the controller;

[0065] The draft measuring device is used to measure the current draft of the hull in real time and send the measured current draft of the hull to the controller.

[0066] Here, the draft gauge is used to measure the ship's current draft in real time. It is usually installed on the hull and can directly sense the vertical distance between the hull and the water surface, thus obtaining accurate draft data.

[0067] Draft measuring instruments can be used in various ways, such as ultrasonic waves and water pressure sensors, without any restrictions.

[0068] Once the current draft of the hull is measured, the draft depth measuring device converts the data into an electrical or digital signal and sends it to the controller 40 via a communication interface, so that the controller 40 can adjust the height of the bracket 30 based on the current draft of the hull.

[0069] The ship sea passage flexible nozzle adjustment system provided in this embodiment of the invention is configured such that one end of each bracket is connected to a support part of the hull, and the other end is connected to a sea passage pipe or flexible nozzle; the controller is electrically connected to several brackets and is used to control the height of each bracket based on the current draft of the hull, so that the deformation of the flexible nozzle meets the expected deformation. In this way, the height of the bracket is automatically adjusted according to the current draft of the hull, ensuring that the deformation of the flexible nozzle is minimized at various drafts, effectively avoiding the risk of the flexible nozzle exceeding tolerance, and improving the safety and reliability of ship navigation.

[0070] This invention also provides a method for adjusting a ship's flexible seakeeping nozzle based on a ship's flexible seakeeping nozzle adjustment system, with reference to... Figure 3 This includes steps 310 and 320.

[0071] Step 310: Obtain the current draft of the ship;

[0072] Step 320: Based on the current draft of the hull, control the height of each support to ensure that the deformation of the flexible connector meets the expected deformation, wherein the height between the two ends of the support is different at different height levels.

[0073] Specifically, in this embodiment, the support frame is a height-adjustable frame. The controller is electrically connected to all the supports and can receive information about the current draft of the hull, and calculate the appropriate height setting for each support frame based on this information. By controlling the height of the supports, the controller can ensure that the deformation of the flexible joint meets expectations, thereby effectively avoiding the risk of deviations in the flexible joint.

[0074] The ship's flexible noose adjustment system first detects the ship's current draft. Based on the detected draft and a preset algorithm or control strategy, the controller determines the appropriate height setting for each support. The controller sends adjustment commands to each support via electrical signals, and the supports adjust to the corresponding height setting accordingly. By flexibly adjusting the height of the supports, the controller can control the deformation of the flexible noose, keeping it within the expected deformation range.

[0075] In some embodiments, controlling the height of each support based on the current draft of the hull includes:

[0076] If a first preset draft depth identical to the current draft depth is detected in the database stored in the server, the height of each support is adjusted based on the optimal height gear combination corresponding to the first preset draft depth; if a first preset draft depth identical to the current draft depth is not detected in the database stored in the server, the height of each support is adjusted based on the optimal height gear combination corresponding to a second preset draft depth; wherein, the second preset draft depth is the preset draft depth with the smallest depth difference from the current draft depth among a plurality of preset draft depths stored in the database stored in the server.

[0077] Here, the server pre-stores a database that records the correspondence between the optimal height gear combination and the preset draft under different preset draft depths.

[0078] Specifically, the correspondence between the preset draft and the optimal height combination is obtained through ship mooring tests. In these tests, the ship's draft is adjusted one by one to each preset draft, such as L1, L2, L3, ..., L... m Then, for each preset draft, the optimal height setting combination with the minimum deformation of the flexible hose was tested.

[0079] The ship's flexible boom adjustment system first obtains the ship's current draft using sensors or other devices. Upon receiving the current draft, the controller communicates with the server to query the database for a first preset draft that matches the current draft. Once the corresponding first preset draft is found, the controller, based on the optimal height settings stored at that first preset draft, sends adjustment commands to each support via a communication protocol, causing them to adjust to the corresponding height settings.

[0080] If the database does not contain a first preset draft that is the same as the current draft, the controller will further search the database for the preset draft that has the smallest depth difference from the current draft, i.e., the second preset draft.

[0081] The controller compares the differences between all preset draft depths in the database and the current draft depth, and selects the preset draft depth with the smallest difference as the second preset draft depth. Based on the optimal height gear combination corresponding to the found second preset draft depth, the controller sends adjustment commands to each support to adjust them to the corresponding height gear.

[0082] In some embodiments, the method includes: m supports, each support including n height levels, where m and n are both positive integers; the method further includes:

[0083] For each preset draft, measure n at the preset draft. m The flexible hose n under each height setting combination m One deformation amount;

[0084] Determine n at the preset draft depth m The height gear combination corresponding to the smallest deformation among the aforementioned deformation amounts is the optimal height gear combination under the preset draft.

[0085] Here, each bracket includes n height settings, so m brackets (30) have n height settings. m In this embodiment, for each preset draft depth, n is measured using a combination of height settings. m Deformation of the flexible joint under different height settings Then the amount of deformation The combination of height settings corresponding to the minimum value is the optimal combination of height settings for this preset draft.

[0086] The flexible nozzle adjustment method for ships providing sea access provided in this invention automatically adjusts the height of the support according to the current draft of the hull, ensuring that the deformation of the flexible nozzle is minimized at various draft depths, effectively avoiding the risk of the flexible nozzle exceeding tolerances, and improving the safety and reliability of ship navigation.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
