[0052] In order to solve the problem of deformation caused by vibration when the ship stern 101 presses the wave, as shown in the prior art, Figure 1 The embodiment provides a wave pressing assembly, which comprises:

[0053] A stern sealing plate 1 is used to seal the ship stern 101.

[0054] Two wave blocking plates 2 are fixedly connected to the edges of the stern sealing plate 1, and the two wave blocking plates 2 arranged at intervals form a containing groove with the stern sealing plate 1.

[0055] A wave pressing plate 3 is arranged in the containing groove, and the wave pressing plate 3 comprises a first plate body 31 and a second plate body 32 which are hingedly connected to each other, and the first plate body 31 and the second plate body 32 are hingedly connected to the stern sealing plate 1, respectively.

[0056] A controller 4 is arranged on the stern sealing plate 1.

[0057] A vibration sensor 41 is arranged on the stern sealing plate 1 and is communicatively connected to the controller 4, and the vibration sensor 41 can detect the vibration frequency of the stern sealing plate 1.

[0058] A plurality of telescopic modules 5 are communicatively connected to the controller 4, each telescopic module 5 has a first end 51 and a second end 52 which are opposite and telescopic, the first end 51 is hingedly connected to the first plate body 31 or the second plate body 32, and the second end 52 is hingedly connected to the stern sealing plate 1, the first end 51 and the second end 52 of each telescopic module 5 can change the relative angle between the first plate body 31 and the second plate body 32 by telescoping, or change the angle formed by the first plate body 31 and the second plate body 32 relative to the stern sealing plate 1.

[0059] The application installs the transom plate 1 on the ship stern 101, and fixes the edges of the two wave plates 2 to the transom plate 1, so that the two wave plates 2 arranged at intervals form a containing groove with the transom plate 1. The wave plate 3 hinged to the transom plate 1 is arranged in the containing groove, and a plurality of telescopic modules 5 are arranged between the wave plate 3 and the transom plate 1, so that the setting angle of the wave plate 3 relative to the transom plate 1 can be changed through the telescopic modules 5. Moreover, the wave plate 2 can also block the upward rolling spray from flowing to the upper side of the wave plate 3, so as to avoid the vortex formed by the spray above the wave plate 3 from causing the up-down vibration of the wave plate 3.

[0060] The wave plate 3 comprises the first plate body 31 and the second plate body 32 hinged to each other, and the edges of the first plate body 31 and the second plate body 32 are hinged to the transom plate 1. Meanwhile, each telescopic module 5 has opposite and telescopic first end 51 and second end 52, each first end 51 is hinged to the first plate body 31 or the second plate body 32, and each second end 52 is hinged to the transom plate 1. When the telescopic module 5 drives the first end 51 and the second end 52 to move telescopically, the first plate body 31 or the second plate body 32 can be driven to rotate relative to the transom plate 1, so that the first plate body 31 and the second plate body 32 can be folded to each other to adjust the relative angle of the two, and can also change the angle relative to the transom plate 1 at the same time.

[0061] In addition, the transom plate 1 is provided with the controller 4 and the vibration sensor 41, and the controller 4 is in communication connection with the vibration sensor 41 and each telescopic module 5. The vibration frequency at the ship stern 101 where the transom plate 1 is located is detected by the vibration sensor 41, and the detected vibration frequency is obtained by the controller 4. According to the relative angle and the inclination angle of the first plate body 31 and the second plate body 32 corresponding to different vibration frequencies, the spray can be suppressed and the vibration can be reduced, and the vibration transmitted from the wave plate 3 to the transom plate 1 can also be reduced, so as to reduce the vibration impact of the ship stern 101 and improve the service life.

[0062] Compared with the ship stern 101 structure of the prior art in the shape of outward protrusion, the wave plate assembly of the application can provide the functions of wave suppression, vibration reduction and buffering by setting the wave plate 3 in the corresponding angle and posture according to the vibration frequency detected by the vibration sensor 41 in the face of different sea conditions. Since the ship stern 101 does not need to be set in the shape of outward protrusion, the use space of the ship stern 101 can be ensured, the ship stern 101 can be avoided to be suspended to reduce the structural deformation of the ship stern 101 caused by the sea wave impact, and the construction difficulty of the ship stern 101 is also reduced.

[0063] It should be noted that the hinging mode of the first plate body 31 and the second plate body 32 to the transom plate 1 can be spherical hinge or multi-angle hinge formed by a plurality of hinge arms, so that the first plate body 31 and the second plate body 32 can be adjusted in three-dimensional direction.

[0064] For the preferred structure of the telescopic module 5, the telescopic module 5 can be a hydraulic telescopic rod or a hydraulic cylinder.

[0065] During the operation of the ship, if the ship encounters severe sea conditions, the ship may travel on the rough sea surface to the wave crest and then fall to hit the sea surface, threatening the structural safety of the ship stern 101. For this purpose, referring to Figure 3 and Figure 4 , the wave compression assembly further comprises an acceleration sensor 42 arranged on the stern plate 1, and the acceleration sensor 42 is also communicatively connected to the controller 4. The acceleration sensor 42 of the embodiment can detect the vertical acceleration of the stern plate 1 and send the detected data to the controller 4. Through the analysis of the controller 4 according to the detection data, it is judged whether the current ship stern 101 is in the falling state. If so, the telescopic module 5 is controlled to act, so as to further adjust the relative angle of the first plate body 31 and the second plate body 32, such as increasing the opening angle of the first plate body 31 and the second plate body 32 to improve the wave compression effect.

[0066] In particular, referring to Figure 2 and Figure 3 , the wave compression assembly further comprises an air bag 6 arranged below the wave compression plate 3 and a inflation module 7 communicating with the inside of the air bag 6, which can inflate or deflate the air bag 6 through the inflation module 7 to increase or decrease the buoyancy of the wave compression plate 3 under the sea surface. Further, the inflation module 7 is communicatively connected to the controller 4, and the inflation rate, inflation amount, deflation rate and deflation amount of the inflation module 7 can also be controlled by the controller 4, so as to accurately adjust the amount of air in the air bag 6. Since the ship will have different draft depths when entering different density water areas, the wave compression assembly of the embodiment can adjust the inflation amount of the air bag 6 below the wave compression plate 3, so as to change the buoyancy of the wave compression assembly in the corresponding water body and adjust to the specified draft depth, so as to keep the draft depth of the ship in each water area consistent.

[0067] Preferably, referring to Figure 3 and Figure 4 , the wave compression assembly further comprises a pressure sensor 43 arranged on the stern plate 1, which can detect the hydraulic pressure of the water body where the stern plate 1 is located. The pressure sensor 43 is communicatively connected to the controller 4, and the current draft depth of the wave compression assembly can be calculated and analyzed by the controller 4. According to the target draft depth and the required buoyancy, the inflation amount or deflation amount of the air bag 6 is obtained, so as to control the inflation module 7 to work, further reducing the deviation between the actual draft depth of the wave compression assembly and the target draft depth.

[0068] Generally, a spreading propeller is usually arranged below the wave compression plate 3. The foam spray generated by the propeller when starting is easy to surround the propeller under the action of the buoyancy and the suction force of the propeller. Optionally, referring to Figure 1A deflector 33 is arranged at the bottom of the first plate body 31 to guide the foam spray away from the propeller, thereby reducing the rotating resistance of the propeller and ensuring the propulsive efficiency of the propeller. Alternatively, a deflector 33 can also be arranged at the bottom of the second plate body 32 to guide the foam spray away from the propeller, thereby reducing the rotating resistance of the propeller. If the deflectors 33 are arranged on both the first plate body 31 and the second plate body 32, the foam spray can be suppressed and guided at the same time, and the large bubbles can be prevented from surrounding the propeller, thereby further improving the propulsive efficiency of the propeller.

[0069] Preferably, the wave suppression plate 3 is made of an elastic material such as rubber, silica gel, etc., which can absorb the impact vibration of the water flow on the wave suppression plate 3, thereby further reducing the vibration transmitted to the stern plate 1.

[0070] In another embodiment, the application also provides a control method applied to any of the above wave suppression assemblies, which comprises:

[0071] S101, obtaining the vibration frequency of the stern plate 1 detected by the vibration sensor 41;

[0072] S102, driving the first end 51 or the second end 52 of each telescopic module 5 to move relative to the telescopic module 5 to change the angle between the first plate body 31 and the second plate body 32 relative to the stern plate 1 according to the vibration frequency.

[0073] In this embodiment, the vibration sensor 41 is used to detect the vibration frequency at the stern 101 where the stern plate 1 is located, and the controller 4 obtains the detected vibration frequency. According to the relative angle and the inclination angle of the first plate body 31 and the second plate body 32 corresponding to different vibration frequencies, the wave can be suppressed and the vibration can be reduced, and the vibration transmitted from the wave suppression plate 3 to the stern plate 1 can also be reduced, thereby reducing the vibration impact on the stern 101 and improving the service life. The wave suppression assembly in this embodiment can have the same effect as the wave suppression assembly in the above embodiments, and will not be described again.

[0074] In actual use, when the vibration frequency detected by the vibration sensor 41 is 0.8 to 1.2 times the natural frequency of the stern plate 1, the preferred angle between the wave suppression plate 3 and the stern plate 1 is 30 to 60 degrees. It should be noted that the angle between the wave suppression plate 3 and the stern plate 1 at this time does not include the relative setting angle of the first plate body 31 and the second plate body 32. When the relative setting angle of the first plate body 31 and the second plate body 32 is combined with the angle between the wave suppression plate 3 and the stern plate 1, the angle between the first plate body 31 and the stern plate 1 alone and the angle between the second plate body 32 and the stern plate 1 alone can be obtained.

[0075] Preferably, the control method of the wave suppression assembly further comprises:

[0076] The vertical acceleration of the transom plate 1 detected by the acceleration sensor 42 can be calculated and analyzed to determine whether the pressure wave assembly is in an overloading state, a stable state or a weightless state.

[0077] According to the obtained vertical acceleration, the first end 51 or the second end 52 of each telescopic module 5 is driven to move relative to the telescopic module 5 to change the relative angle between the first plate body 31 and the second plate body 32. Different setting angles of the first plate body 31 and the second plate body 32 in different states of the pressure wave assembly can reduce the impact of the pressure wave plate 3 on the water surface.

[0078] Since the ship is in a weightless state when it falls from the wave crest in rough sea conditions, in order to reduce the impact of the pressure wave assembly falling onto the sea surface, specifically, when the vertical acceleration of the transom plate 1 downward is greater than 2.5 m / s2and less than 3.5 m / s2, the relative angle of the first plate body 31 and the second plate body 32 can be set to 45 degrees to 90 degrees, which can open the pressure wave plate 3 to suppress the sea surface and reduce the impact vibration of the transom plate 1 on the sea surface. Similarly, when the vertical acceleration of the transom plate 1 downward is greater than 3.5 m / s2and less than 5 m / s2, the relative angle of the first plate body 31 and the second plate body 32 can be set to 90 degrees to 120 degrees, which can further open the pressure wave plate 3 to suppress the sea surface and further reduce the impact of the sea surface on the transom plate 1. If the vertical acceleration of the transom plate 1 downward is greater than 7 m / s2, the relative angle of the first plate body 31 and the second plate body 32 is set to 0 degrees to retract the pressure wave plate 3, reducing the direct impact of the pressure wave plate 3 on the sea surface and damaging the pressure wave plate 3.

[0079] Another preferred embodiment, the control method of the pressure wave assembly further comprises:

[0080] The inflation module 7 is driven to inflate or deflate the air bag 6 to change the buoyancy of the transom plate 1 relative to the water body.

[0081] The inflation rate, inflation amount, deflation rate and deflation amount of the inflation module 7 can be controlled by the controller 4 to accurately adjust the amount of air in the air bag 6. Since the ship has different draft depths when entering different density water areas, the inflation amount of the air bag 6 under the pressure wave plate 3 is adjusted to change the buoyancy of the pressure wave assembly in the corresponding water body to adjust to the specified draft depth, which can keep the draft depth of the ship consistent in each water area.

[0082] Further, in the control method of the pressure wave assembly described above, the step of driving the inflation module 7 to inflate or deflate the air bag 6 comprises:

[0083] The pressure value of the transom plate 1 in the water body detected by the pressure sensor 43 is obtained, and the controller 4 can calculate and analyze the current draft depth of the pressure wave assembly.

[0084] According to the pressure value of the transom plate 1 in the water body, the difference between the current draft and the target draft is calculated, and then the required buoyancy is calculated, so as to obtain the inflation or deflation amount of the air bag 6, so as to drive the inflation module 7 to inflate or deflate the air bag 6, so as to reduce the deviation between the actual draft of the pressure wave assembly and the target draft.

[0085] For example, when the draft increases by 0.01 meters, the inflation volume of the air bag 6 is increased by 20 cubic meters. When the pressure wave assembly of the embodiment is arranged on a ship of different size, the inflation amount of the air bag 6 is positively related to the volume and weight of the ship on which the pressure wave assembly is arranged. The embodiment is only illustrative and is not limited.

[0086] Optionally, the application also provides another control method applied to any of the above pressure wave assemblies, comprising:

[0087] S201, obtaining the vibration frequency of the transom plate 1 detected by the vibration sensor 41;

[0088] S202, driving the first end 51 or the second end 52 of each telescopic module 5 to move relative to the telescopic module 5 to change the angle between the first plate body 31 and the second plate body 32 relative to the transom plate 1 according to the vibration frequency;

[0089] S203, obtaining the vertical acceleration of the transom plate 1 detected by the acceleration sensor 42;

[0090] S204, driving the first end 51 or the second end 52 of each telescopic module 5 to move relative to the telescopic module 5 to change the relative angle between the first plate body 31 and the second plate body 32 according to the vertical acceleration.

[0091] S205, obtaining the pressure value of the transom plate 1 in the water body detected by the pressure sensor 43;

[0092] S206, driving the inflation module 7 to inflate or deflate the air bag 6 according to the pressure value of the transom plate 1 in the water body to change the buoyancy of the transom plate 1 relative to the water body.

[0093] The control method of the pressure wave assembly in the embodiment can have the same effect as the control method of the pressure wave assembly in the above embodiment, and the embodiment will not be repeated.

[0094] In addition, the application also provides a ship comprising a ship body 100 and the pressure wave assembly of any of the above embodiments, and the transom plate 1 of the pressure wave assembly blocks the ship stern 101 of the ship body 100. The pressure wave assembly in the embodiment can have the same structure and effect as the pressure wave assembly in the above embodiment, and the embodiment will not be repeated.
