Description

Technical Field

[0001] The present invention relates to the technical field of wave suppression plates, and specifically to an adjustable stern wave suppression plate structure. Background Technique

[0002] The stern wave suppression plate is a flat plate device installed at the rear end of the ship's bottom. It can form a certain angle with the extension line of the ship's bottom plate. The wave suppression plate can suppress the phenomenon of waves hitting the stern, improve the maneuverability of the ship under high-speed or complex sea conditions. At the same time, for high-speed ships, using the wave suppression plate can help reduce the angle of the bow rising, which also plays a positive role in reducing the navigation resistance. The current stern wave suppression plate structure is not convenient for automatically controlling the angle of the wave suppression plate to adjust with the driving speed. Most use hydraulic control angle adjustment structures. Once the power fails, it will directly affect the ship's performance. At the same time, the rigid angle adjustment structure has poor anti-collision effect and is not convenient for automatically adjusting the ship's attitude. When the ship is tilted and unilateral wave suppression is carried out, it will directly affect the ship's driving safety. At the same time, the wave suppression plate is immersed in seawater for a long time and is prone to attaching marine organisms, affecting the flow resistance of the water flow during wave suppression and the stability of the ship's stern, and is not convenient for keeping clean.

[0003] Therefore, we propose an adjustable stern wave suppression plate structure. Summary of the Invention

The length of the swing plate is greater than that of the pressing plate, which is more convenient for using the lever principle to control the downward turning of the pressing plate. When the pressing plate and the swing plate hit impurities such as pin stones underwater, they have a buffering and retracting effect because the water pressure is not a rigid support, avoiding the problem of poor anti-collision effect in the traditional hydraulic control method of directly fixing and lowering the swing plate. The wave pressing work can be controlled without a cumbersome electrification control structure, and the stagnation of the pressing plate angle caused by power failure can be avoided.

By turning up the pressing plate on the other side, under the action of water flow, the ship can be pressed downward, which is convenient for pressing and assisting the tilted side to stabilize the ship and prevent the ship from tilting too much during turning, affecting the navigation safety.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention provides a technical solution: An adjustable stern wave suppressing plate structure, including a wave suppressing mounting member 1.

The fixed rack 1011 is fixedly installed on the side of the wave suppressing mounting plate 101 through bolts; four through grooves are provided on the wave suppressing mounting plate 101; the four through grooves on the wave suppressing mounting plate 101 are used for passing through bolts and installing on the stern of the ship.

[0033] Among them, the wave suppressing mounting member 1 further includes: a rotating mounting frame 1012, a pneumatic propulsion cylinder 102, a piston shaft 103, a pressing plate 104, and a rotating connecting frame 105. The rotating mounting frame 1012 is fixedly mounted on the wave suppressing mounting plate 101 by bolts; the tail of the pneumatic propulsion cylinder 102 is rotatably mounted on the rotating mounting frame 1012 through a shaft seat; the piston shaft 103 is slidably inserted into the pneumatic propulsion cylinder 102, and the piston shaft 103 is sealingly fitted to the pneumatic propulsion cylinder 102; the pressing plate 104 is rotatably mounted on the wave suppressing mounting plate 101; the rotating connecting frame 105 is fixedly mounted on the pressing plate 104 by bolts; the end of the piston shaft 103 is rotatably mounted on the rotating connecting frame 105; the unidirectional moving member 2 includes: conveying rollers 201, a conveyor belt 202, a unidirectional bearing 203, and a swinging gear 204. Two conveying rollers 201 are rotatably mounted on the pressing plate 104, and the end parts of the two conveying rollers 201 respectively pass through the pressing plate 104; the conveyor belt 202 is rotatably sleeved on the two conveying rollers 201; the conveyor belt 202 is located outside the pressing plate 104; a unidirectional bearing 203 is fixedly mounted on the end part of the conveying roller 201 close to the wave suppressing mounting plate 101, and a swinging gear 204 is fixedly sleeved on the outside of the unidirectional bearing 203; the swinging gear 204 meshes with the fixed rack 1011; the conveyor belt 202 is used for suppressing waves; the cleaning and fitting member 3 includes: a cleaning strip 301 and a cleaning spring 302. The side of the cleaning strip 301 is elastically fitted to the outside of the conveyor belt 202; the cleaning strip 301 is slidably inserted into the bottom of the wave suppressing mounting plate 101; a row of cleaning springs 302 are fixedly mounted on the tail of the cleaning strip 301, and the other ends of the row of cleaning springs 302 are respectively connected to the inside of the wave suppressing mounting plate 101; the row of cleaning springs 302 are respectively located inside the wave suppressing mounting plate 101;The cleaning scraper 301 has an inclined structure on both sides. The one-way moving part 2 can realize the automatic control of the one-way conveying movement of the conveyor belt 202 during the process of the pressure plate 104 rotating to press the waves, so as to keep the conveyor belt 202 in a recycling state, and ensure that the wave pressing quality of the conveyor belt 202 remains unchanged. At the same time, the cleaning fitting part 3 can be used to automatically clean the conveyor belt 202 when it moves, so as to prevent impurities from adhering to its surface. At the same time, the cleaning fitting part 3 can achieve elastic retraction to avoid jamming, so it is more practical, can improve the cleanliness of the surface of the conveyor belt 202, has a more reasonable structure, and can prevent ships that have been moored for a long time from being affected by impurities adhering to the surface of the conveyor belt 202 and affecting the actual wave pressing effect. At the same time, if a large amount of attachments are attached to the surface of the conveyor belt 202, it will cause increased vibration during wave pressing, affecting the navigation quality of the ship. This structure can automatically control cleaning. When the ship is docked, the waves will also drive the swing test piece 4 to rotate for driving work. Cleaning work can also be performed during navigation, ensuring the real-time cleanliness of the conveyor belt 202 in this structure. No electric cleaning or manual cleaning is required. When the pressure plate 104 is controlled to rotate to adjust the wave pressing angle, the swing gear 204 will mesh and roll on the fixed rack 1011, and cooperate with the one-way limiting structure of the one-way bearing 203 to drive the conveying roller 201 to rotate in one direction, realizing one-way driving of the conveyor belt 202 for transportation. During the process, the cleaning scraper 301 can scrape and clean in real time. ;

[0034] Among them, the swing test piece 4 includes: a swing mounting shaft 401, a swing plate 402, a guide plate 4021, and a lower electromagnet 403. The swing mounting shaft 401 is fixedly installed on the side of the wave-pressing mounting plate 101; the swing plate 402 is rotatably installed on the swing mounting shaft 401; a torsion spring is sleeved on the swing mounting shaft 401; the torsion spring on the swing mounting shaft 401 is connected between the swing mounting shaft 401 and the swing plate 402; the bottom of the swing plate 402 is fixedly installed with the guide plate 4021; the swing plate 402 is inclined to the water surface; the length of the swing plate 402 is greater than that of the pressing plate 104; the lower electromagnet 403 is fixedly embedded on the swing plate 402; the swing plate 402 is used to be controlled to rotate by water pressure when the ship is traveling at high speed; by adopting the swing test piece 4, its structure can move along with the ship's navigation. At the same time, the guide plate 4021 can play a guiding role, improve the navigation stability, and play the role of a fin plate. At the same time, by adopting the swing plate 402, as the navigation speed increases and the bow of the ship tilts up, the swing plate 402 can be gradually controlled by the sea water flow to rotate upward under the action of water pressure on the horizontal plane, and can be used for driving work. At the same time, the length of the swing plate 402 is greater than that of the pressing plate 104, which can make it more convenient to utilize the lever effect to control the pressing plate 104 to turn down, ensuring the rationality of this structure. By using the method of relying on water pressure of the swing plate 402 to control the lowering of the pressing plate 104, the pressing plate 104 and the swing plate 402 have a buffer retraction effect when hitting impurities such as pin stones underwater. Because the water pressure is not a rigid support, it avoids the problem of poor anti-collision effect in the traditional way of directly fixing and lowering the swing plate 402 by hydraulic control.

[0035] Among them, the air pressure shunt member 5 includes: an air cushion 501 and a flow pipe 502. The air cushion 501 is fixedly installed on the swing plate 402; the flow pipe 502 is fixedly installed on the side of the air cushion 501; the air cushion 501 is located below the lower electromagnet 403; the air pressure shunt member 5 further includes: a discharge pipe 503, and the discharge pipe 503 is fixedly installed on the side of the air cushion 501; the other end of the discharge pipe 503 is fixedly installed on the air pressure propulsion cylinder 102 on the same side; the discharge pipe 503 is used to conduct air pressure; the swing positioning member 6 includes: a positioning pressure plate 601 and an upper electromagnet 602. The positioning pressure plate 601 is fixedly installed on the swing mounting shaft 401 through a bracket; the bottom of the positioning pressure plate 601 is fixedly installed on the top of the air cushion 501; the upper electromagnet 602 is fixedly installed on the positioning pressure plate 601; the upper electromagnet 602 is aligned with the lower electromagnet 403 on the same side; after the upper electromagnet 602 and the upper electromagnet 602 are energized, they repel each other. By using the swing positioning member 6 in cooperation with the air pressure shunt member 5, it is possible to control the swing of the pressure plate 104 underwater through air pressure. The control method is simple and stable, and at the same time, the air pressure method is relatively more flexible. This structure can control the wave suppression work without a cumbersome electrification control structure, which can avoid the angle of the pressure plate 104 from stagnating due to power failure and affecting navigation. This structure has a longer service life. At the same time, the two pressure plates 104 can be independently controlled. When the swing plate 402 is gradually controlled by the sea water flow to rotate upward under the action of water pressure on the horizontal plane, it can squeeze the air cushion 501. At this time, the air cushion 501 can input air pressure into the discharge pipe 503 and introduce it into the air pressure propulsion cylinder 102 to realize the pushing out of the piston shaft 103 and downward extrusion of the pressure plate 104 to rotate.

[0036] Embodiment 2, on the basis of Embodiment 1, the balance control member 7 includes: a detection cylinder 701, a sliding piston column 702, and an electrical connection column 703. The detection cylinder 701 is fixedly installed at the ends of the two flow pipes 502; the detection cylinder 701 communicates with the two air cushions 501; the sliding piston column 702 is slidably sleeved in the middle of the detection cylinder 701; electrical connection columns 703 are fixedly installed on both sides of the sliding piston column 702 respectively; the balance control member 7 further includes: an electrical connection cylinder 704 and a centering spring 705. Electrical connection cylinders 704 are fixedly installed on both sides inside the detection cylinder 701; the two electrical connection columns 703 are respectively used to fit the electrical connection cylinders 704; the electrical connection columns 703, the electrical connection cylinders 704, the upper electromagnet 602 and the upper electromagnet 602 on the same side are connected in series to a power source; centering springs 705 are sleeved on both sides inside the detection cylinder 701, and the centering springs 705 are respectively located on both sides of the two sliding piston columns 702; insulating layers are provided outside the two centering springs 705. The balance control member 7 can be used to detect the balance state of the two extrusion air cushions 501. By using the method of detecting air pressure, the skew attitude of the ship can be reflected. When the ship is sailing smoothly and normally, the pressure conditions of the two extrusion air cushions 501 should be relatively consistent. Once the pressure deviation between the two extrusion air cushions 501 is large, it can reflect that the swing plate 402 on one side is highly compressed by the water pressure, and the ship is skewed downward here. The upper turning of the pressing plate 104 on the other side can be directly controlled. By turning up the pressing plate 104 on the other side, under the action of the water flow, the ship can be pressed down, which is convenient for pressing down and assisting the tilted side to stabilize the ship and prevent the ship from turning with too large an inclination angle, affecting the navigation safety. The control of this structure is simple, avoiding the usually cumbersome manual control of traditional wave suppression plates. This structure can facilitate the adjustment of the ship's attitude and has stronger functionality. Because the two pressing plates 104 are respectively immersed in seawater, once the ship tilts, the air cushion 501 on the lower side of the tilt will push the sliding piston column 702 under the action of air pressure, and the electrical connection column 703 on the moving side will fit the electrical connection cylinder 704. At this time, the upper electromagnet 602 and the upper electromagnet 602 are respectively energized and repel each other, and the air cushion 501 is stretched and pulled upward to rotate the pressing plate 104, which is convenient for guiding the water flow to press down on the higher side of the tilt at this time, playing a balancing role.

[0037] Working principle of this embodiment: First, four through slots on the wave-suppressing mounting plate 101 are bolted to the stern of the hull. When the ship is sailing, the swing plate 402 can be gradually controlled by the sea water flow under the action of water pressure to rotate upward. When it rotates upward, it can squeeze the air cushion 501. At this time, the air cushion 501 can input air pressure into the discharge pipe 503 and introduce it into the air pressure propulsion cylinder 102 to push out the piston shaft 103 and squeeze the pressing plate 104 to rotate downward. At the same time, under the impact of the waves, the swing plate 402 can also rotate slightly to drive the pressing plate 104 to rotate. When the pressing plate 104 is controlled to rotate to adjust the wave-suppressing angle, the conveying roller 201 is also driven to rotate at this time. At this time, the swing gear 204 will roll meshingly on the fixed rack 1011. With the one-way limiting structure of the one-way bearing 203, it will only idle when rotating in the reverse direction. At this time, as the pressing plate 104 swings up and down and rotates, the swing gear 204 will be meshingly driven to drive the conveying roller 201 to rotate unidirectionally, realizing the unidirectional driving of the conveyor belt 202 for conveying. During the process, the cleaning scraper 301 can scrape and clean in real time. Once the adhesion of impurities on the surface of the conveyor belt 202 is too large or it is damaged, the cleaning scraper 301 can elastically retract and compress the cleaning spring 302. Workers can conduct regular inspections. Once the ship tilts, at this time, the pressures of the two air cushions 501 are different. The air cushion 501 on the lower side of the tilt will push the sliding piston column 702 under the action of air pressure and compress the centering spring 705 on the moving side. At this time, the electrical contact column 703 on the moving side of the sliding piston column 702 will fit the electrical contact cylinder 704. At this time, the upper electromagnet 602 and the upper electromagnet 602 are respectively energized and repel each other, increasing the downward rotation angle of the swing plate 402. At this time, the air cushion 501 on the higher side of the tilt is stretched and sucks back the air pressure propulsion cylinder 102 to assist in contracting the piston shaft 103 and pulling the pressing plate 104 upward to rotate and assist in adjustment.
