The application installs the stern sealing plate 1 on the stern 101, and fixedly connects the edges of the two manger plates 2 on the stern sealing plate 1, so that the two manger plates 2 and the stern sealing plate 1 which are arranged at intervals form a containing groove. The wave pressing plate 3 hinged with the stern-seal plate 1 is arranged in the accommodating groove, and a plurality of telescopic modules 5 are arranged between the wave pressing plate 3 and the stern-seal plate 1, so that the setting angle of the wave pressing plate 3 relative to the stern-seal plate 1 can be changed through the telescopic modules 5. Moreover, the breakwater 2 can also prevent the upward-tumbling spray from flowing to the upper side of the breakwater 3, and prevent the spray from forming a vortex above the breakwater 3 to cause the breakwater 3 to vibrate up and down.
The wave plate 3 comprises a first plate body 31 and a second plate body 32 which are hinged with each other, and edges of the first plate body 31 and the second plate body 32 are hinged with the stern seal board 1. At the same time, each expansion module 5 has opposite and telescopic first and second ends 51, 52, each first end 51 being hinged to the first or second plate body 31, 32 and each second end 52 being hinged to the transom 1.

In addition, a controller 4 and a vibration sensor 41 are provided on the transom 1, and the controller 4 is in communication with both the vibration sensor 41 and each telescoping module 5.

Since the stern 101 does not need to be arranged in an outward-floating shape, the use space of the stern 101 can be ensured, the stern 101 can be prevented from being suspended, the structural deformation of the stern 101 caused by sea wave impact can be reduced, and the construction difficulty of the stern 101 can be reduced.
It should be noted that, the hinge manner of the first plate 31 and the second plate 32 with the stern board 1 may be ball hinge, or may be multi-angle hinge formed by a plurality of hinge arms, so that the first plate 31 and the second plate 32 can perform angle adjustment in three-dimensional directions.
For the preferred construction of the telescopic module 5, the telescopic module 5 may be a hydraulic telescopic rod or a hydraulic cylinder.
If a ship encounters severe sea conditions during the running process of the ship, the ship may run to the peak on the rough sea and fall down to strike the sea, thereby threatening the structural safety of the stern 101. To this end, referring to fig. 3 and 4, the wave pressing assembly further comprises an acceleration sensor 42 arranged on the transom plate 1, the acceleration sensor 42 being further communicatively connected to the controller 4. The acceleration sensor 42 of the present embodiment can detect the vertical acceleration of the stern sealing plate 1, send the detected data to the controller 4, analyze the detected data by the controller 4, determine whether the stern 101 is in a falling state currently, if so, control the expansion module 5 to act, thereby further adjusting the relative angle between the first plate 31 and the second plate 32, for example, increasing the opening and closing angle between the first plate 31 and the second plate 32 to improve the wave pressing effect.
In particular, referring to fig. 2 and 3, the wave pressing assembly further includes an air bag 6 disposed under the wave pressing plate 3 and an air inflation module 7 communicating with the inside of the air bag 6, and the air bag 6 can be inflated or deflated by the air inflation module 7 to increase or decrease buoyancy of the wave pressing plate 3 under the sea surface. Further, the inflation module 7 is in communication connection with the controller 4, and the inflation rate, the inflation amount, the deflation rate and the deflation amount of the inflation module 7 can be controlled by the controller 4, so that the air amount in the air bag 6 can be accurately adjusted. Because the ship has different draft when entering into the waters with different densities, the wave pressing assembly of the embodiment can adjust the specified draft by adjusting the inflation amount of the air bags 6 under the wave pressing plate 3, thereby changing the buoyancy of the wave pressing assembly in the corresponding water body and keeping the draft of the ship in each water body consistent.
Preferably, referring to fig. 3 and 4, the wave pressing assembly further comprises a pressure sensor 43 arranged at the transom 1, and the pressure sensor 43 is capable of detecting the hydraulic pressure of the water body in which the transom 1 is located. The pressure sensor 43 is in communication connection with the controller 4, the current draft of the wave pressing assembly can be calculated and analyzed by the controller 4, and the inflation amount or deflation amount of the air bag 6 is obtained according to the target draft and the required buoyancy, so that the inflation module 7 is controlled to work, and the deviation between the actual draft of the wave pressing assembly and the target draft is further reduced.
Generally, a propagation screw is generally arranged below the breakwater 3, and foam spray generated when the screw is started easily surrounds the vicinity of the screw under the action of buoyancy and suction force of the screw. Optionally, referring to fig. 1, a deflector 33 is provided at the bottom of the first plate 31, and foam spray is guided away from the propeller by the deflector 33, so that the rotational resistance to the propeller can be reduced, thereby ensuring the propulsive efficiency of the propeller. Alternatively, a deflector 33 may be provided at the bottom of the second plate 32, which can also guide the foam spray away from the propeller to reduce the rotational resistance to the propeller. If the guide plates 33 are arranged on the first plate 31 and the second plate 32 at the same time, foam spray can be pressed and guided at the same time, so that large bubbles are reduced to surround the vicinity of the propeller, and the propulsion efficiency of the propeller is further improved.
Preferably, the breakwater 3 is made of an elastic material, such as rubber, silica gel, etc., which is capable of absorbing the impact vibration of the water flow on the breakwater 3, further reducing the vibration transferred to the transom 1.
In another embodiment, the present application further provides a control method applied to any one of the above wave pressing assemblies, including:
s101, acquiring the vibration frequency of the stern transom plate 1 detected by the vibration sensor 41;
s102, driving the first end 51 or the second end 52 of each expansion module 5 to move in an expansion mode relative to the expansion modules 5 according to the vibration frequency so as to change the angle formed by the first plate 31 and the second plate 32 relative to the transom 1.
In the embodiment, the vibration sensor 41 is used to detect the vibration frequency of the stern 101 where the stern sealing plate 1 is located, the controller 4 obtains the detected vibration frequency, and according to the relative angles and the inclination angles of the first plate 31 and the second plate 32 corresponding to different vibration frequencies, the spray can be suppressed, the vibration can be reduced, and the vibration transmitted to the stern sealing plate 1 by the spray pressing plate 3 can be reduced, so that the vibration impact of the stern 101 is reduced, and the service life is prolonged. The wave pressing assembly in this embodiment may have the same effect as the wave pressing assembly in the above embodiment, and this embodiment will not be described again.
In practical use, the vibration frequency detected by the vibration sensor 41 may be adjusted to a preferred angle of 30 to 60 degrees between the breakwater 3 and the transom plate 1 if it is between 0.8 and 1.2 times the natural frequency of the transom plate 1. It should be noted that, at this time, the angle formed between the wave plate 3 and the stern board 1 does not include the relative set angles of the first plate 31 and the second plate 32, and the combination of the relative set angles of the first plate 31 and the second plate 32 to the angle formed between the wave plate 3 and the stern board 1 may result in the angle formed between the first plate 31 and the stern board 1, and the angle formed between the second plate 32 and the stern board 1.
Preferably, the control method of the wave pressing assembly further comprises the following steps:
the vertical acceleration of the stern transom plate 1 detected by the acceleration sensor 42 is obtained, and the obtained vertical acceleration can be calculated and analyzed to obtain that the wave pressing assembly is in an overweight state, a stable state or a weightlessness state.
The first end 51 or the second end 52 of each telescopic module 5 is driven to move telescopically relative to the telescopic module 5 according to the obtained vertical acceleration so as to change the relative angle between the first plate 31 and the second plate 32. The wave pressing assembly is provided with different setting angles of the first plate body 31 and the second plate body 32 in different states, so that the impact between the wave pressing plate 3 and the liquid level can be reduced.
Since the ship is in a weightless state when falling from a wave crest in a severe sea condition, in order to reduce the impact of the wave pressing assembly falling onto the sea surface, specifically, when the downward vertical acceleration of the transom plate 1 is greater than 2.5m/s2 and less than 3.5m/s2, the relative angle between the first plate 31 and the second plate 32 may be set to 45 degrees to 90 degrees, so that the wave pressing plate 3 may be opened to press the sea surface, and the impact vibration between the transom plate 1 and the sea surface may be reduced. Similarly, when the downward vertical acceleration of the transom 1 is greater than 3.5m/s2 and less than 5m/s2, the relative angle between the first plate 31 and the second plate 32 may be set to 90 degrees to 120 degrees, further expanding the heave plate 3 to compress the sea surface, and also further reducing the sea surface to the transom 1. If the downward vertical acceleration of the stern transom 1 is greater than 7m/s2, the relative angle between the first plate 31 and the second plate 32 is set to be 0 degrees, so as to retract the breakwater 3, and reduce the direct impact between the breakwater 3 and the sea surface to damage the breakwater 3.
Another preferred control method of the wave pressing assembly further includes:
the inflation module 7 is driven to inflate or deflate the air bag 6 so as to change the buoyancy of the stern transom plate 1 relative to the water body.
The present embodiment can control the inflation rate, the inflation amount, and the deflation rate and the deflation amount of the inflation module 7 through the controller 4, thereby precisely adjusting the amount of air in the airbag 6. Because the ships have different draft when entering into the waters with different densities, the embodiment changes the buoyancy of the wave assembly in the corresponding water body to adjust the specified draft by adjusting the inflation amount of the air bags 6 under the wave pressing plate 3, and can keep the draft of the ships in each water body consistent.
Further, in the control method of the wave pressing assembly, the step of driving the inflation module 7 to inflate or deflate the air bag 6 includes:
the pressure value of the stern 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 of the wave pressing assembly.
The difference value between the current draft and the target draft is calculated according to the pressure value of the water body where the stern transom 1 is positioned, and then the required buoyancy is calculated, so that the inflation amount or deflation amount of the air bag 6 is obtained, the inflation module 7 is driven to inflate or deflate the air bag 6, and the deviation between the actual draft of the wave pressing assembly and the target draft can be reduced.
Illustratively, every 0.01 meter increase in draft, the inflated volume of the bladder 6 is correspondingly increased by 20 cubic meters. When the wave-pressing assembly of the present embodiment is disposed on vessels of different sizes, the inflation amount of the air bag 6 is positively correlated with the volume and weight of the vessel in which the wave-pressing assembly is disposed, and the present embodiment is merely illustrative and not particularly limited.
Optionally, the application further provides another control method applied to any wave pressing assembly, which comprises the following steps:
