Technical Field
[0001] This invention relates to the field of marine technology, specifically to a concealed marine flag deployment and suspension system and method. Background Technology
[0002] When a ship needs to hold a ceremony, it usually hangs colorful flags from bow to stern to meet certain ceremonial requirements.
[0003] Generally, flags are hoisted at the top of the midships mast spanner or the fore and aft bulkheads of the superstructure, connecting to the flagpoles or decks at the bow and stern, respectively. On large ships, the distance between the fore and aft flags is considerable, and the area of a single flag is large, making manual deployment and retrieval over long distances difficult. Therefore, the flag deployment and retrieval systems on large ships typically include suspension cables, electric winches for deploying / retrieving the cables, guide pulleys, and bow and stern securing equipment. In existing domestic ships, the fore and aft cable winches are placed outside the deck, with several independent single-drum electric winches horizontally positioned, requiring significant open deck space and impacting the ship's stealth capabilities. With the increasing sophistication of large ship designs, the external space of the mast and superstructure has been significantly reduced, while higher requirements have been placed on the overall stealth performance of the ship. Therefore, without affecting the operation of raising and lowering the flags, the main equipment for raising and lowering the ship's flags should be placed inside the cabin as much as possible to reduce the occupation of the exposed parts of the superstructure and improve the overall stealth. Summary of the Invention
[0004] To address the aforementioned shortcomings of existing technologies, a system and method for the deployment and suspension of marine flags with a concealed main body are provided, which reduces the occupation of exposed parts of the superstructure and improves overall stealth.
[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: The main body of the concealed marine flag deployment and suspension system is characterized by: including The storage compartment has a hatch on its top, and the hatch is equipped with an opening and closing device. An electric winch unit, one or more electric winch units are placed in a storage compartment. The electric winch unit is equipped with two drums, on which a flag rope and a tether rope are wound respectively. The inner ends of the flag rope and the tether rope are fixed to the drums. Each flag rope is equipped with one electric winch unit and one tether rope. The top guide cable pulley and the end guide cable pulley are installed and fixed on the top of the superstructure, and the end guide cable pulleys are installed and fixed to the stern or bow of the hull in a detachable connection manner. Steering cable trolleys, with multiple sets of steering cable trolleys deployed on the superstructure between the storage compartment and the top cable trolley; The guide rope has one end detachably connected to the outer end of the flag-hanging rope and the flag-pulling rope, and the other end is pulled by the operator or external power. The outer ends of the flag-hanging cable and the flag-drawing cable are taken out of the storage compartment by the pulley and pass through the steering guide cable trolley and the top guide cable trolley in sequence; the flag-drawing cable passes through the end guide cable trolley and turns back to the top guide cable trolley, and the outer ends of the flag-drawing cable and the flag-hanging cable are connected.
[0006] According to the above technical solution, based on the number and location of the flag cables, a corresponding number of top guide cable pulleys and end guide cable pulleys are set up, and each group includes two top guide cable pulleys and one end guide cable pulley.
[0007] According to the above technical solution, multiple pairs of first eye plates are set on the top and sides of the superstructure according to the direction of the flag-holding cable and the flag-hanging cable. The steering guide cable pulley is installed on the superstructure through the first eye plates. A second eye plate is installed at the bow or stern of the hull, and the end guide cable pulley is connected to the second eye plate through a shackle.
[0008] According to the above technical solution, the flag hanging cable is made of steel wire rope, and the flag pulling cable is made of high-strength fiber cable; the other end of the pulling cable is manually pulled by the operator.
[0009] According to the above technical solution, the electric winch unit adopts two independent drums and their drive motors and transmission mechanisms arranged parallel to each other along their center lines, and the center lines of the two drums are staggered by a certain distance in height.
[0010] According to the above technical solution, the opening and closing device includes a hatch cover located at the hatch, a sill located on the hatch, and a guide assembly integrated on the sill; the guide assembly includes limiting rollers and guide rollers, with multiple sets of guide rollers arranged in parallel at intervals within the area of the sill, and the axis of the guide rollers being parallel to the center line of the drum; two limiting rollers are arranged in parallel at intervals within the area of the sill, and the axis of the limiting rollers being perpendicular to the center line of the drum; the same set of flag ropes and tethering ropes pass through the area between the same set of guide rollers.
[0011] According to the above technical solution, the guide roller is located directly above the limiting roller, and the guide roller is arranged near the upper edge of the sill.
[0012] According to the above technical solution, it also includes a shackle, with the outer ends of the flag cable and the tow cable respectively connected to both ends of the shackle; the second eye plate and the end guide cable trolley are connected to both ends of the shackle; the storage compartment is located in the area below the side deck of the superstructure.
[0013] The method for hanging marine flags with a concealed main body employs the marine flag deployment and hanging system described above, and includes the following steps: S1: Install end guide cable pulleys and steering guide cable pulleys on the hull; S2: Open the hatch opening and closing device, and the pull rope and electric winch unit will sequentially pass the flag-holding ropes and flag-hanging ropes corresponding to multiple colored flags through the limiting roller, guide roller, steering guide rope trolley, and top guide rope trolley. S3: Pull the flag cable to the stern or bow of the hull, pass it through the end guide cable pulley, and then turn back to the top guide cable pulley; S4: Connect the ends of the flag-holding cable and the flag-hanging cable, and start the corresponding electric winch unit to pull the flag-hanging cable to the end guide cable pulley; disconnect the connected ends of the flag-holding cable and the flag-hanging cable, and connect the end of the flag-hanging cable to the second eye plate; S5: Connect the flag hooks of the colorful flags to the flag hanging rope, and connect the top flag hook of the colorful flag to the flag pulling rope, so that the flag can be pulled to the corresponding height position by the flag pulling rope.
[0014] According to the above technical solution, the flag cable is made of high-strength fiber cable. In step S3, the electric winch unit is started to gradually release the flag cable. Then, the operator manually pulls the flag cable to the bow or stern of the hull and through the end guide cable pulley. Subsequently, the flag cable is manually pulled back to the top guide cable pulley.
[0015] The present invention has the following beneficial effects: 1. Both the steering guide cable pulley and the end guide cable pulley are detachably connected to the hull and are equipped with storage compartments. When the flags are not in use, the electric winch unit, flag-hanging cable, tether cable, steering guide cable pulley, end guide cable pulley, and guide cable are all placed in the storage compartments, and the opening and closing devices are closed. When the flags are needed, the end guide cable pulley and steering guide cable pulley are installed on the hull. Operators then use the guide cable in conjunction with the electric winch unit to pass the outer ends of the flag-hanging cable and tether cable through the opening and closing devices of the storage compartment, then through the various pulleys, and connect at the top guide cable pulley to form a closed loop. Finally, start the electric winch unit to pull the flag-hanging cable to the stern or bow second eye plate and connect it to the second eye plate; then connect the flag hooks of the colorful flags in series on the flag-hanging cable, and connect the uppermost flag hook of the colorful flag to the flag-hanging cable, so that the flag can be pulled to the corresponding height position by the flag-hanging cable to achieve the hanging of the colorful flag; conversely, the colorful flag can be stored.
[0016] Based on the above structural measures, the suspension system is divided into a permanently fixed part and a detachable part. Depending on the usage of the flags, the detachable part is selected to be stored in a storage compartment or installed on the hull. The permanently fixed part, with the electric winch unit as its main body, is installed in the storage compartment via a steering guide trolley and guiding components within the opening and closing device. This overcomes the limited space for flag deployment and suspension system arrangement in exposed areas of large ships, while also supporting the ship's stealth design.
[0017] 2. During the flag hoisting process, existing flag-holding and flag-hanging cables generally use steel wire ropes. However, based on practical analysis, the flag-hanging cable bears the greatest load, so it still uses stainless steel wire rope. The flag-holding cable bears a much lower load than the flag-hanging cable, so a high-strength fiber cable is used to facilitate direct manual pulling by the crew. This eliminates the need for the guide cable to pull the flag-holding cable towards both ends of the bow and stern; only manual pulling by the operator is required to pull both the flag-holding and flag-hanging cables onto the top guide cable pulley. This effectively and significantly reduces the length of the guide cable, and simplifies manual operation, thus eliminating the need for an electric winch for the guide cable and reducing the space requirements of that winch.
[0018] 3. A guide assembly including a limiting roller and a guide roller is set in the opening and closing device. The limiting roller restricts the range of motion of the cable during the pulling process, and the guide roller guides the direction of the cable being pulled out, so as to guide and limit multiple cables and avoid interference between multiple cables during the pulling process.

Detailed Implementation
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] Reference Figures 1-11 As shown, the present invention provides a concealed marine flag deployment and suspension system.
[0022] Example 1 include Storage compartment 1, with a hatch on the top of the storage compartment and an opening and closing device 2 on the hatch; Electric winch unit 3 (also includes electrical control box 3-1 in the figure), one or more electric winch units are placed in the storage compartment. The electric winch unit is equipped with two drums, and the two drums are respectively wound with flag rope 4 and traction rope 5. The inner ends of the flag rope and traction rope are fixed to the drums; each flag rope is equipped with one electric winch unit and one traction rope. The top guide cable pulley 6 and the end guide cable pulley 7 are installed and fixed on the top of the superstructure 8, and the end guide cable pulley is installed and fixed to the stern or bow of the hull in a detachable connection manner. Steering cable trolley 9, multiple sets of steering cable trolleys are arranged on the superstructure between the storage compartment and the top cable trolley; it can effectively stagger the running routes of the two cables, so that the cables can turn to the top cable trolley after they come out of the opening and closing device.
[0023] The guide rope 10 has one end detachably connected to the outer ends of the flag hanging rope and the flag pulling rope, and the other end is pulled by the operator or external power. The outer ends of the flag-hanging cable and the flag-drawing cable are taken out of the storage compartment by the pulley and pass through the steering guide cable trolley and the top guide cable trolley in sequence; the flag-drawing cable passes through the end guide cable trolley and turns back to the top guide cable trolley, and the outer ends of the flag-drawing cable and the flag-hanging cable are connected.
[0024] In this embodiment, both the steering guide cable trolley and the end guide cable trolley are detachably connected to the hull and are housed in a storage compartment. When the flags are not in use, the electric winch unit, flag-hanging cable, tether cable, steering guide cable trolley, end guide cable trolley, and guide cable are all placed in the storage compartment, and the opening and closing device is closed. When the flags are needed, the end guide cable trolley and steering guide cable trolley are installed on the hull, and the operator, using the guide cable in conjunction with the electric winch unit, guides the outer ends of the flag-hanging cable and tether cable through the opening and closing device of the storage compartment, then through the various trolleys, connecting at the top guide cable trolley to form a closed loop. Finally, start the electric winch unit to pull the flag-hanging cable to the stern or bow second eye plate and connect it to the second eye plate; then connect the flag hooks of the colorful flags in series on the flag-hanging cable, and connect the uppermost flag hook of the colorful flag to the flag-hanging cable, so that the flag can be pulled to the corresponding height position by the flag-hanging cable to achieve the hanging of the colorful flag; conversely, the colorful flag can be stored.
[0025] Based on the above structural measures, the suspension system is divided into a permanently fixed part and a detachable part. Depending on the usage of the flags, the detachable part is selected to be stored in a storage compartment or installed on the hull. The permanently fixed part, with the electric winch unit as its main body, is installed in the storage compartment via a steering guide trolley and guiding components within the opening and closing device. This overcomes the limited space for flag deployment and suspension system arrangement in exposed areas of large ships, while also supporting the ship's stealth design.
[0026] In Example 1, based on the number and location of the flag cables, a corresponding number of top guide cable pulleys and end guide cable pulleys are set up, with each group containing two top guide cable pulleys and one end guide cable pulley. In this example, a single flag cable and a flag-drafting cable are pulled out from the storage compartment, pass through multiple steering guide cable pulleys and a single top guide cable pulley, and are then suspended at the top guide cable pulley. Subsequently, the operator continues to pull the flag-drafting cable through the pulley, passing it through the end guide cable pulley located at the end of the hull and returning it to the top guide cable pulley. Finally, the outer end of the flag-drafting cable and the outer end of the flag cable are connected.
[0027] Example 2 The structure and principle of Embodiment 2 are similar to those of Embodiment 1, with the following differences: To facilitate the installation of end guide cable pulleys and steering guide cable pulleys on the hull, multiple pairs of first eye plates 11 are installed on the top and sides of the superstructure according to the direction of the flag-holding cable and the flag-hanging cable. The steering guide cable pulley is installed on the superstructure through the first eye plates. A second eye plate 12 is installed at the bow or stern of the hull, and the end guide cable pulley is connected to the second eye plate through shackles. The first and second eye plates serve as the mounting points for the steering guide cable pulley and the end guide cable pulley on the hull, respectively. When colored flags are used, various second eye plates used to connect the flag-holding cable and the flag-holding cable are connected to the hull through the first and second eye plates. When colored flags are not needed, the steering guide cable pulley, the end guide cable pulley, the flag-holding cable, and the flag-holding cable are removed from the hull, thereby improving the stealth performance of the hull.
[0028] Example 3 The structure and principle of Example 3 are similar to those of Example 1 or 2, with the difference being that the flag-hanging cable uses a steel wire rope, while the tethering cable uses a high-strength fiber rope; the other end of the tethering cable is manually pulled by the operator. In the flag-hanging operation, existing tethering and hanging cables generally use steel wire ropes; however, based on practical analysis, the hanging cable bears the greatest load, so it still uses a stainless steel wire rope. The tethering cable bears a much smaller load than the hanging cable, so a high-strength fiber rope is used to facilitate direct manual pulling by the crew, thus eliminating the need for the tethering cable to pull the tethering cable towards the bow and stern. Only manual pulling by the operator is required to pull both the tethering and hanging cables onto the top guide cable pulley. This effectively and significantly reduces the length of the tethering cable, and simplifies manual operation, thereby eliminating the need for an electric winch for the tethering cable and reducing the space requirements of that winch.
[0029] Example 4 The structure and principle of Embodiment 4 are similar to those of Embodiments 1-3, except that: preferably, the electric winch unit uses two independent drums, their drive motors, and transmission mechanisms arranged parallel to each other along their centerlines, with the centerlines of the two drums offset by a certain distance in height. This arrangement reduces the space occupied on the horizontal plane while ensuring the winding and unwinding of the two cables, thus minimizing the overall size of the integrated double-drum cable winding / unwinding electric winch. The integrated electric winch unit also eliminates the need to consider the spacing between the two drums, effectively reducing the overall space requirements. Alternatively, the electric winch unit can use two independent single-drum electric winches or two independent horizontal winches mounted on a shared base; however, this arrangement requires a larger deck space than the preferred embodiment.
[0030] Example 5 The structure and principle of Embodiment 5 are similar to those of Embodiments 1-4, except that: the opening and closing device includes a hatch cover at the hatch, a sill at the hatch, and a guide assembly integrated on the sill; the guide assembly includes limiting rollers and guide rollers, with multiple sets of guide rollers arranged in parallel at intervals within the area of the sill, and the axis of the guide rollers being parallel to the center line of the drum; two limiting rollers are arranged in parallel at intervals within the area of the sill, and the axis of the limiting rollers being perpendicular to the center line of the drum; the same set of flag ropes and tow ropes pass through the area between the same set of guide rollers.
[0031] In this embodiment, during the process of the same set of flag cables and traction cables being pulled out of the storage compartment by the guide cables within the corresponding electric winch unit, the range of motion of the cables during the pulling process is limited by limiting rollers, and the direction of pulling is guided by guide rollers, thereby guiding and limiting multiple cables and preventing interference between them during the pulling process. A hatch cover is provided at the top of the hatch cofferdam, which is closed after the cables are retracted to meet the compartment airtightness requirements.
[0032] In embodiment 5, preferably, in order to ensure that each cable passes between two adjacent guide rollers and avoids interference during the passage of multiple cables, the guide roller is located directly above the limiting roller and is arranged near the upper edge of the sill.
[0033] In embodiments 1-5, a shackle 13 is included to facilitate the connection between the flag-hanging cable and the tow cable, with the outer ends of the flag-hanging cable and the tow cable respectively connected to both ends of the shackle; in addition, to facilitate the connection of the end guide cable trolley to the second eye plate, the second eye plate and the end guide cable trolley are connected to both ends of the shackle; the storage compartment is located in the area below the side deck 14 of the superstructure.
[0034] This invention also provides a method for hanging marine flags with a concealed main body, employing the marine flag deployment and hanging system with a concealed main body as described above; such as Figure 6-11 As shown, it includes the following steps: S1: Install end guide cable pulleys and steering guide cable pulleys on the hull; specifically, according to the number of flags to be hoisted, install a corresponding number of end guide cable pulleys at the bow or stern of the hull using shackles, install a corresponding number of top guide cable pulleys on the top of the superstructure, and install a corresponding number of steering guide cable pulleys in the middle of the superstructure.
[0035] S2: Open the hatch opening and closing device. The pull rope, in conjunction with the electric winch unit, sequentially passes the flag-holding and flag-hanging cables corresponding to the multiple colored flags through the limiting roller, guide roller, steering guide cable trolley, and top guide cable trolley. Specifically, the electric winch unit is started to release the flag-hanging and flag-holding cables appropriately. The flag-holding and flag-holding cables are then passed through the limiting roller and guide roller to the open area outside the hatch via the pull rope or other short ropes. Afterward, the flag-holding and flag-holding cables are passed through the steering guide cable trolley in the middle of the superstructure and hoisted onto the trolley. Finally, at the uppermost open area, the flag-holding and flag-holding cables are pulled to the corresponding top guide cable trolleys via the pull ropes and passed through them. Then, they are hoisted to the open area below.
[0036] S3: Pull the flag cable to the stern or bow of the hull, pass it through the end guide cable pulley, and then turn back to the top guide cable pulley. Specifically, start the electric winch unit to gradually release the flag cable, and then pull the other end of the flag cable to the end guide cable pulley position at the stern by manpower or machinery. Pass the flag cable through the end guide cable pulley and pull it back to the exposed part under the top guide cable pulley by manpower or machinery.
[0037] S4: Connect the ends of the flag-pulling cable and the flag-hanging cable, and start the corresponding electric winch unit. The electric winch unit will wind up the flag-pulling cable and release the flag-hanging cable, pulling the flag-hanging cable to the end guide cable pulley. Then, disconnect the connected ends of the flag-pulling cable and the flag-hanging cable, and connect the end of the flag-hanging cable to the second eye plate via a shackle.
[0038] S5: Connect the flag hooks to the flag hanging rope in series, and then connect the flags to the hooks one by one; connect the top flag hook to the flag pulling rope, and tighten the flag pulling rope to pull the flag to the corresponding height. The flags are stored by reversing the basic steps.
[0039] Preferably, the flag cable is made of high-strength fiber cable. In step S3, the electric winch unit is activated to gradually lower the flag cable, and then the operator manually pulls the flag cable to the bow or stern of the hull and through the end guide cable pulley. Subsequently, the flag cable is manually pulled back to the top guide cable pulley. This eliminates the need for the traction cable to pull the flag cable to both ends of the bow and stern; only the operator manually pulls the traction cable to pull the flag cable and the flag-hanging cable onto the top guide cable pulley. This effectively and significantly reduces the length of the traction cable, and the operation is easier for personnel, thus eliminating the need for an electric winch for the traction cable and reducing the space requirements of the winch.
[0040] The above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent changes made in accordance with the claims of the present invention shall still fall within the protection scope of the present invention.
