Description

Technical Field

[0001] The present invention relates to the technical field of ship application devices, and in particular to an active self-deforming flexible device for suppressing liquid tank sloshing and a suppression method thereof. Background Art

[0002] In existing technologies, liquid sloshing in liquid tanks is a common phenomenon in various ship transportation systems, most notably liquefied natural gas (LNG) carriers. This liquid sloshing behavior can cause a shift in the ship's roll resonance frequency and induce multiple coupled roll modes to exhibit amplitude peaks within a specific frequency range, thereby reducing the overall stability of the ship. Furthermore, the transient impact pressure caused by sloshing poses a serious threat to the tank bulkheads and hull structure. Therefore, effective mitigation solutions are urgently needed to address the adverse effects of liquid tank sloshing during navigation, thereby enhancing the safety and stability of ships during navigation.

[0003] At present, the main measure to solve this problem is to install baffles or sway plates in the liquid tank, but the current mainstream baffles or sway plates have the following disadvantages: the baffles or sway plates have a single configuration and are difficult to adapt to complex sea conditions; baffles and sway plates are passive anti-rolling devices and cannot make targeted adjustments to the actual liquid tank swaying conditions in real time in the real marine environment; traditional baffles and sway plates have poor scalability and are difficult to adapt to the configuration requirements of liquid tanks of different sizes.

[0017] The present invention also provides a method for suppressing liquid tank sloshing by an active self-deforming flexible device, comprising the following steps: S1. Select the appropriate height to weld the transverse plate to the inner wall of the tank according to the designed height of the liquid level in the tank and the tank size, and adjust the positions of the left and right moving mechanisms at the same time; S2.

[0024] The technical solutions of the present application are further described below by means of the accompanying drawings and examples.

[0027] The active self-deformation flexible device includes a liquid tank fixing structure 1, an active self-deformation structure 2 and a rotating shaft 3. The liquid tank fixing structure 1 can replace different specifications of cross plates according to the actual size of the liquid tank to adapt to the engineering needs of the actual liquid cargo transport ship.

[0028] As shown in Figure 7As shown, the liquid tank fixing structure 1 includes a transverse plate 1-2, and the two transverse plates 1-2 are fixed to the inner walls on both sides of the liquid tank by welding. An inner guide rail 1-3 is provided on the transverse plate 1-2, and a moving mechanism is provided on the inner guide rail 1-3. The moving mechanism includes a left moving mechanism 1-4 and a right moving mechanism 1-5. The outer surfaces of the left moving mechanism 1-4 and the right moving mechanism 1-5 are both provided with threaded holes, which can be fixedly connected to the first rotating shaft connector 3-5.

[0029] A transverse plate motor 1-1 is provided on the outside of the transverse plate 1-2. The transverse plate motor 1-1 is connected to the left moving mechanism 1-4 and the right moving mechanism 1-5 respectively through a translation screw. The transverse plate motor 1-1 can control the moving mechanism to move horizontally along the inner guide rail 1-3 in the transverse plate 1-2.

[0030] like Figure 8 、 Figure 9 、 Figure 10 As shown, the active self-deforming structure 2 is composed of a flexible film 2-1, a connecting block 2-2, a fixed plate 2-3, a first power control system 2-4 and a second power control system 2-5. The flexible film 2-1 is connected to the fixed plate 2-3 through the connecting blocks 2-2 on both sides thereof, and the number of the connecting blocks 2-2 and the fixed plate 2-3 are both two.

[0031] A single tenon 2-6 is provided at one end of the fixed plate 2-3, and a double tenon 2-7 is provided at the other end of the fixed plate 2-3 for connecting to the rotating shaft 3; a first power control system 2-4 and a second power control system 2-5 are respectively provided in the two fixed plates 2-3, and the first power control system 2-4 and the second power control system 2-5 both have sensors, controllers, drivers and built-in motors.

[0032] The sensor is used to detect the liquid sloshing condition in the liquid tank; the driver is used to adjust the rotation amplitude and rotation frequency of the built-in motor; the sensor, driver, and built-in motor are all electrically connected to the controller, and the built-in motor can drive the flexible film 2-1 to move axially along the rotating shaft 3. Its motion structure is well known to technicians in this field and will not be repeated here.

[0033] The active self-deforming structure 2 is connected to the liquid tank fixed structure 1 through a moving mechanism. The active self-deforming structure 2 is connected to the left moving mechanism 1-4 and the right moving structure 1-5 of the liquid tank fixed structure 1 through a first rotating shaft. The built-in motors in the first power control system 2-4 and the second power control system 2-5 can drive the flexible film 2-1 to move axially along the rotating shaft 3, and the moving mechanism is driven to translate in the direction of the inner guide rail 1-3 in the transverse plate 1-2 through the transverse plate motor 1-1, thereby realizing real-time changes in the shape of the anti-roll plate, solving the problem that the traditional anti-roll device has a single configuration and cannot cope with complex sea conditions, and is more adaptable to the actual situation during the ship's navigation.

[0034] The active self-deforming structure 2 is composed of a plurality of flexible film structures nested with each other through a rotating shaft 3. The number of flexible film structures can be appropriately increased or decreased according to different liquid tank structures to achieve an ideal anti-swaying effect.

[0035] The rotating shaft 3 includes a first rotating shaft and a second rotating shaft, which are respectively connected to the moving mechanism and the active self-deforming structure.

[0036] like Figure 11 As shown, the first rotating shaft is composed of a first rotating shaft upper shaft cap 3-1, a first shaft rod 3-2, a first rotating shaft lower shaft cap 3-3 and a first rotating shaft connector 3-5. The first rotating shaft upper shaft cap 3-1 and the first shaft rod 3-2 are connected by a bearing. The surface of the first rotating shaft connector 3-5 has a thread for connecting to the left moving mechanism 1-4 or the right moving mechanism 1-5 on the liquid tank fixed structure 1, thereby connecting the tip of the first rotating shaft to the liquid tank fixed structure 1.

[0037] like Figure 12 As shown, the side of the first rotating shaft upper shaft cap 3-1 is provided with a first rotating shaft upper snap-in 3-10, and the side of the first rotating shaft lower shaft cap 3-3 is provided with a first rotating shaft lower snap-in 3-11. The first rotating shaft upper snap-in 3-10 and the first rotating shaft lower snap-in 3-11 are snap-connected with the double tenon 2-7. The side of the first shaft rod 3-2 is provided with a first snap-in 3-4, and the first snap-in 3-4 is snap-connected with the single tenon 2-6, thereby connecting both sides of the first rotating shaft to the active self-deformation structure 2.

[0038] like Figure 13 、 Figure 14 As shown, the second rotating shaft is composed of a second rotating shaft upper cap 3-6, a second shaft rod, and a second rotating shaft lower cap 3-7. A second rotating shaft upper snap-in 3-8 is provided on the side of the second rotating shaft upper cap 3-6, and a second rotating shaft lower snap-in 3-9 is provided on the side of the second rotating shaft lower cap 3-7. The second rotating shaft upper snap-in 3-8 and the second rotating shaft lower snap-in 3-9 engage with the double tenon 2-7. A second snap-in is provided on the side of the second shaft rod, and the second snap-in engages with the single tenon 2-6. Thus, both sides of the second rotating shaft are connected to the active self-deforming structure 2.

[0039] Both the rotating shaft 3 and the active self-deforming structure 2 are modular in design, and the number of flexible membranes 2-1 can be appropriately increased or decreased based on the space limitations of the cabin, making the overall structure more adaptable to actual engineering needs. The first power control system 2-4 and the second power control system 2-5 in the active self-deforming structure 2, along with the mobile mechanism in the liquid tank fixed structure 1, jointly achieve the posture transformation of the active self-deforming structure, allowing multiple flexible membranes to freely combine into different postures to respond to different types of oscillation and wave damping, successfully achieving real-time changes in the morphology of the sway control plate. This solves the problem that the single configuration of traditional anti-roll devices is difficult to adapt to actual sway conditions, meeting the needs of suppressing sway under complex oscillation conditions during ship navigation. At the same time, the number of mobile mechanisms can be appropriately increased based on the actual size of the liquid tank to meet actual engineering needs.

[0040] At the same time, the flexible film 2-1 can absorb the energy generated by the sloshing liquid during the interaction with the liquid in the liquid tank. At the same time, since the flexible film 2-1 significantly reduces the liquid elevation during the vibration process, the disorder of the free liquid surface is reduced. At the same time, there is a fluid-solid coupling effect between the flexible film 2-1 and the liquid in the liquid tank, which changes the original natural frequency of the liquid, reduces the probability of resonance, and improves the structural safety of the ship during navigation.

[0041] The dimensions of each structure of the device of the present invention can be adjusted according to actual conditions, and the overall size of the device can be enlarged or reduced according to the actual conditions of the liquid tank. At the same time, the device has good anti-corrosion and waterproof properties. The flexible film 2-1 of the present invention is made of PVC, and the remaining parts are mainly made of metal.

[0042] Example 2 The present invention also provides a method for suppressing liquid tank sloshing by an active self-deforming flexible device, comprising the following steps: S1. According to the designed height of the liquid level in the liquid tank and the size of the liquid tank, select the appropriate height to weld the transverse plate 1-2 to the inner wall of the liquid tank, and adjust the positions of the left moving mechanism 1-4 and the right moving mechanism 1-5; S2. Select an appropriate number of active self-deforming structures 2 according to the actual size of the liquid tank and connect them to the rotating shaft 3. At the same time, connect the first rotating shaft connector 3-5 to the left moving mechanism 1-4 and the right moving mechanism 1-5 in the liquid tank fixed structure 1; S3. The flow field information of the liquid surface in the liquid tank is detected by the sensor and the information is fed back to the controller. The staff manually adjusts or automatically adjusts the rotation amplitude and movement distance of the built-in motor and the horizontal plate motor 1-1 according to the feedback information of the controller.

[0043] Therefore, the application adopts the above-mentioned active self-deformation flexible device for suppressing the sloshing of the liquid tank and the suppressing method, which can adapt to complex sea conditions, adapt to the configuration requirements of liquid tanks of different sizes, and solve the problem of poor suppression effect of the existing roll reduction device.

[0044] It is worth noting that the contents not elaborated in the application are all prior art and are well known to those skilled in the art.

[0045] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application but not to limit it, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: it can still modify or equivalently replace the technical solutions of the present application, and these modifications or equivalent replacements also cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
