Description

Technical Field

[0001] This invention relates to the field of ship damage stability model testing technology, and in particular, to an active control device for ship damage stability model testing. Background Technology

[0002] Ship damage stability is a crucial performance indicator for assessing navigational safety. When a ship suffers damage to its side or bottom due to accidents such as collisions, grounding, or reef strikes, it may sink or capsize, posing a serious threat to navigational safety. The survivability of a damaged ship is an important indicator for evaluating its safety. Based on research into the motion characteristics of damaged ships, and considering the environmental conditions of the damaged ship, it is necessary to establish prediction methods and model testing techniques for the unstable motion of damaged ships, providing effective technical means for assessing the survivability of damaged ships. Currently, in active control of ship damage, experiments mainly involve using heavy objects to instantly open the damage opening and using a cover plate driven by a motor to open the damage opening. The heavy object method can only study one type of damage opening size. While opening different sizes of damage openings with a cover plate can achieve different sizes of research, the impact of waves on the ship during navigation varies. If the wave direction receives a large impact force, the opening of the cover plate will be subject to a certain impact force, and the opening process will be relatively slow. This method cannot meet the requirement of rapid opening time of the damage opening. Summary of the Invention

[0003] To address the above problems, the present invention provides an active control device for ship damage stability model testing.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an active control device for ship damage stability model testing, the structure of which includes a hull, a railing, and a control room. The hull is provided with a railing, the control room is installed on the hull, the hull is provided with a damage opening, and the control room includes a connecting rod, a support base, and a transmission rack. The support base is connected to the damage opening through the connecting rod, and the connecting rod is provided with a transmission rack, which contacts and engages with the damage opening.

[0005] As a further improvement of the present invention, the damaged opening includes a turntable, a clamping device, a sealing strip, a baffle, a movable groove, a hinge interface, a connecting shaft, and a magnetic block. The turntable and the edge of the baffle are fitted with a clearance fit. A connecting shaft is welded to the baffle. The connecting shaft is fixed to the turntable through the hinge interface. The inner side of the baffle is provided with a movable groove and a magnetic block. The movable groove is fitted with a clamping device, which is fixed on the turntable. The sealing strip is fixed on both sides of the baffle.

[0006] As a further improvement of the present invention, the movable groove extends between adjacent baffles, and the adjacent magnetic blocks are opposite magnetic to each other and are magnetically attracted to each other.

[0007] As a further improvement of the present invention, the turntable and the transmission rack are engaged in a meshing manner, and the baffle is a fan-shaped structure with four baffles that are fitted together to form a circular shape.

[0008] As a further improvement of the present invention, the movable groove includes a groove body, a compact guide block, a swing rod, and a fixed opening. The compact guide block is fitted inside the groove body, and the compact guide block is connected by the swing rod. The swing rod is mechanically connected to the fixed opening.

[0009] As a further improvement of the present invention, the compact guide block includes a connection port, a support cavity, an open opening, a partition, a suction cup, and a spring. The connection port is fixed with the support cavity, and the support cavity is provided with a spring and a suction cup inside. The partition and the support cavity are an integrated structure, and the partition has an open opening at its center.

[0010] As a further improvement of the present invention, the suction cup is movably fitted to the open opening, two springs are provided and are respectively connected to the inner wall of the support cavity, and the outer surface of the partition layer is in close contact with the inner wall of the groove.

[0011] The beneficial effects of this invention are: The invention features four baffles of equal size in the breach opening. The baffles are connected to a hinge interface via a connecting shaft. When the breach opening is closed, the hinge interface electrically folds the baffles during breach. The folding effect of the baffles can be coordinated with the impact direction of the waves, enabling breach studies of different sizes. At the same time, it can also open the breach opening more quickly and effectively.

[0012] The baffle of this invention is equipped with a sealing strip and a magnetic block. The cooperation of the sealing strip and the magnetic block can ensure the tightness of the baffle closure. The movable groove on the baffle is equipped with a clamping device. The clamping device passes through the inside of the movable groove, which closes the adjacent baffles together more tightly from the inside, improves the closing performance of the baffle and prevents it from being opened by wave impact.

[0013] The clamping device of this invention works in conjunction with a turntable. The rotation of the turntable is used to fix and separate the clamping device from the movable groove. The movable groove adopts a crescent-shaped structure. The wide end makes it easier for the swing rod to enter the movable groove, while the narrow end can improve the tightness between the compact guide block and the movable groove, making it more secure.

[0014] The compact guide block of this invention is provided with an integrated support cavity and partition. Both the support cavity and the partition are made of rubber. When the compact guide block enters the movable groove, as the space shrinks, the support cavity is compressed by the groove, causing the partition to adhere to the surface of the suction cup. The suction cup is exposed in the open opening and is tightly adsorbed and fixed inside the groove by the suction cup, which further improves the engagement stability between the clamping device and the movable groove.

The railing 2 is mounted on the hull 1, and the control room 3 is installed on the hull 1. The hull 1 has a damage port 11. The control room 3 includes a connecting rod 31, a support base 32, and a transmission rack 33. The support base 32 is connected to the damage port 11 via the connecting rod 31. The transmission rack 33 is mounted on the connecting rod 31 and engages with the damage port 11. The damage port 11 includes a turntable 111, a clamping device 112, and a sealing strip. 113, baffle 114, movable groove 115, hinge interface 116, connecting shaft 117, and magnet 118. The turntable 111 is clearance-fitted with the edge of the baffle 114. The connecting shaft 117 is welded to the baffle 114 and fixed to the turntable 111 via the hinge interface 116. The inner side of the baffle 114 is provided with a movable groove 115 and a magnet 118. A clamping device 112 is movably fitted inside the movable groove 115 and fixed to the turntable 111. The sealing strip 113 is fixed to both sides of the baffle 114. The movable groove 114... 5. The magnetic blocks 118 are mutually opposite magnetic and magnetically attracted to each other. The turntable 111 and the transmission rack 33 are engaged. The baffles 114 are fan-shaped and there are four of them. The four baffles 114 are fitted together to form a circle. The movable groove 115 includes a groove body 15a, a compact guide block 15b, a swing rod 15c, and a fixing port 15d. The compact guide block 15b is fitted inside the groove body 15a. The compact guide block 15b is connected by the swing rod 15c. The swing rod 15c is mechanically connected to the fixing port 15d. The compact guide block 15a is connected to the transmission rack 33. b includes a connection port 5b1, a support cavity 5b2, an open opening 5b3, a partition 5b4, a suction cup 5b5, and a spring 5b6. The connection port 5b1 is fixed to the support cavity 5b2. The support cavity 5b2 is equipped with a spring 5b6 and a suction cup 5b5. The partition 5b4 and the support cavity 5b2 are an integral structure. The center of the partition 5b4 is provided with an open opening 5b3. The suction cup 5b5 is movably fitted into the open opening 5b3. Two springs 5b6 are provided and are respectively connected to the inner wall of the support cavity 5b2. The outer surface of the partition 5b4 is in close contact with the inner wall of the groove 15a.

[0024] The working principle of the active control device in the above technical solution is explained below: In the present invention, during the damage test, the damage opening 11 is engaged with four baffles 114 of equal structural size. The baffles 114 are folded open using hinge interfaces 116, and the opening direction is the same as the wave direction. During operation, the hinge interfaces 116 are electrically driven. Figure 4As shown, a single baffle 114 is opened inward. By opening different baffles 114, damage studies of openings of different sizes can be conducted. This also allows for faster and more effective opening of the damage opening 11. After the experiment, the baffle 114 returns to its original position. During closure, the sealing strips 113 on the sides of the baffle 114 fit tightly together, and the magnetic blocks 118 are magnetically attracted together, ensuring better sealing of the baffle 114 and preventing positional shifts during repositioning. When the baffle 114 is closed, to prevent strong wave impact from breaking through it, a movable groove 115 is provided between adjacent baffles 114. The movable groove 115 cooperates with the clamping device 112, and the transmission gear... The 33 meshes with the turntable 111, causing the turntable 111 to rotate. During the rotation, the turntable 111 drives the swing rod 15c to enter along the direction of the groove 15a. As the swing rod 15c continues to penetrate deeper into the groove 15a, the compact guide block 15b connected to the swing rod 15c is subjected to pressure at the narrow end of the groove 15a. At this time, the support cavity 5b2 located on both sides of the connection port 5b1 is continuously compressed, causing the suction cup 5b5 to be exposed at the open port 5b3. The suction cup 5b5 is used to tightly adhere to the inner wall of the groove 15a, and the clamping device 112 is tightly fixed inside the movable groove 115, thereby firmly locking the baffles 114 together and increasing the impact force of the baffles 114. The support cavity 5b2 and the partition 5b4 are an integrated structure, and the surface of the partition 5b4 is arc-shaped. When the swing rod 15c extends into the movable groove 115, it can be more smoothly. When it is not subjected to the pressure of the groove 15a, the suction cup 5b5 is placed inside the support cavity 5b2, ensuring that the swing rod 15c can effectively extend into the movable groove 15.
