Description

Technical Field

[0001] The present invention relates to the field of ship testing, and in particular to a wave crushing plate device for cavitation water tunnel testing and a preparation method thereof. Background Art

[0002] The flue plate is a large flat plate installed at the top of the working section's segmented inner cavity. It can be considered the upper surface of the fluid during operation. It's typically made of metal or rigid PVC. The flue plate conforms to the waterline of the test ship model and needs to be tailored to the waterline profile of each model. During installation, workers install the flue plate piece by piece within the cavitation tunnel, necessitating extensive installation and adjustment. Furthermore, performing this installation within the tunnel is inconvenient. Due to the varying shapes of ship models, when a replacement model needs to be replaced, the flue plate must be removed piece by piece from the tunnel and then assembled and installed piece by piece, adjusting the position of each piece to the new model's shape. Furthermore, after the flue plate is installed, gaps may exist between the multiple pieces. This can cause water to leak through these gaps during testing, causing surface fluctuations that can affect the uniformity of the flow field. Summary of the Invention

[0050] The present invention provides a wave crusher device for cavitation water tunnel testing, which is used to be set in the cavitation water tunnel and located around the ship model 7, and can reduce the height and strength of waves, thereby reducing the force of waves directly impacting the hull or structure. Figure 1 and Figure 2 As shown, it includes a fixed wave-squeezing plate 1, multiple movable wave-squeezing plates 2, a main frame 3, multiple vertical adjustment frames 4, and multiple longitudinal adjustment frames 5. In this embodiment, the fixed wave-squeezing plate 1 and the movable wave-squeezing plate 2 are made of low-density PP or PVC plastic materials to reduce their own weight and increase the convenience of installation operation.

[0051] The fixed heave plate 1 is generally rectangular in shape and is fixed to the top of the working section of the cavitation tunnel, parallel to the horizontal plane. When the ship model 7 is replaced, the fixed heave plate 1 can remain in the cavitation tunnel. One end of the movable heave plate 2 is cut to match the waterline of the ship model 7. The other end is used to form a sealed connection with the other movable heave plates 2 and the fixed heave plate 1, and can adopt a conventional flat rectangular shape.

[0052] like Figure 1 and Figure 2As shown, the main frame 3 is provided with a longitudinal guide rail extending along the longitudinal direction of the ship model 7 and a plurality of first adapter frames 33 that can slide along the longitudinal guide rail. The first adapter frames 33 are used to connect the movable wave-pressing plate 2. The position of the movable wave-pressing plate 2 can be adjusted along the longitudinal guide rail by the first adapter frames 33 until the shape cut out by the movable wave-pressing plate 2 is aligned with the water surface line of the ship model 7. The vertical adjustment frame 4 includes a bracket body 41 for fixedly connecting to the top of the cavitation water tunnel and a vertical adjustment mechanism provided on the bracket body 41. When assembled outside the cavitation water tunnel, the bracket body 41 can be supported on a ground bracket 8. The ground bracket 8 includes a base 81 and a vertical bracket 82, which connects the vertical adjustment mechanism to the main frame 3. Each longitudinal adjustment frame 5 is perpendicular to the longitudinal guide rail, and multiple longitudinal adjustment frames 5 are arranged along the longitudinal direction of the ship model 7, that is, the longitudinal direction of the main frame 3. Each of the longitudinal adjustment frames 5 can slide along the longitudinal guide rail of the main frame 3. Each of the longitudinal adjustment frames 5 is provided with a transverse guide rail and at least two second adapter frames 51 that can slide along the transverse guide rail and are located on both sides of the ship model 7. The second adapter frame 51 is used to connect the movable wave-breaking plate 2.

[0053] When the ship model 7 needs to be replaced, the wave-crushing plate device for cavitation water tunnel testing of the present invention only needs to remove the vertical adjustment frame 4, move the vertical adjustment frame 4 and the movable wave-crushing plate 2 out of the cavitation water tunnel, replace it with a new movable wave-crushing plate 2, adjust its height and horizontal position, and then move the entire device into the cavitation water tunnel for hoisting. During hoisting, only the vertical adjustment frame 4 needs to be installed, and the fixed wave-crushing plate 1 does not need to be replaced. Compared with the prior art solution of removing all wave-crushing plates piece by piece, installing them piece by piece in the cavitation water tunnel, and adjusting their height and horizontal position, this solution can greatly improve the convenience and efficiency of the installation operation. In addition, when it is suitable for a narrower ship model 7, the second adapter frame 51 is selected to connect the movable wave crushing plate 2. When it is suitable for a wider ship model 7, the movable wave crushing plate 2 is moved outward and can be connected through the first adapter frame 33. When the width occupied by the movable wave crushing plate 2 is larger, the movable wave crushing plate 2 can be connected together through the first adapter frame 33 and the second adapter frame 51. This makes the wave crushing plate device of the present invention basically applicable to all ship models 7.

[0054] like Figure 1As shown, the main frame 3 is a rectangular frame comprising two parallel longitudinal frames 31 and two parallel transverse frames 32. In this embodiment, the main frame 3 also includes multiple transverse reinforcement frames 34, each of which is fixed to one of the longitudinal frames 31 at one end and to another longitudinal frame 31 at the other end, to reinforce the main frame 3. The multiple transverse reinforcement frames 34 divide the main frame 3 into multiple longitudinally arranged areas. The longitudinal frames 31, transverse frames 32, longitudinal adjustment frames 5, and longitudinal reinforcement frames 34 each include upper and lower beams, vertical beams, and diagonal beams, forming a triangular structure that provides stable mechanical properties. In this embodiment, the upper and lower beams of each longitudinal frame 31 are each equipped with a set of longitudinal guide rails. The set of longitudinal guide rails includes an inner longitudinal guide rail 312 located inside the upper or lower beam and an outer longitudinal guide rail 311 located outside the upper or lower beam. The two rails in a set of longitudinal guide rails are of the same height. Multiple first adapter frames 33 constitute multiple groups of first adapter frames 33, each group of first adapter frames 33 includes a first adapter frame 33 that can slide along the outer longitudinal guide rail 311 and a first adapter frame 33 that can slide along the inner longitudinal guide rail 312. Each group of first adapter frames 33 can slide in one of the above-mentioned areas, and a longitudinal adjustment frame 5 can slide along the inner longitudinal guide rail 312 in one of the above-mentioned areas.

[0055] In this embodiment, if Figure 2 As shown, the upper beam and the lower beam of the longitudinal adjustment frame 5 are both provided with a set of transverse guide rails, which include a first transverse guide rail 53 provided on one side of the longitudinal adjustment frame and another transverse guide rail (not shown in the figure) provided on the other side of the longitudinal adjustment frame. Figure 1 As shown, the longitudinal adjustment frame 5 is provided with two groups of second adapter frames 51, and the two groups of second adapter frames 51 are respectively located on both sides of the ship model 7, and each group of the second adapter frames 51 includes a second adapter frame 51 that can slide along the first transverse guide rail 53 in the group of transverse guide rails and another second adapter frame 51 that can slide along the second transverse guide rail in the group of transverse guide rails.

[0056] like Figure 1 As shown, the wave-crushing plate device includes four vertical adjustment brackets 4, and the vertical adjustment mechanisms of the four vertical adjustment brackets 4 are connected to the four corners of the main frame 3 in a one-to-one correspondence. By adjusting the vertical brackets, not only the height of the main frame 3 can be adjusted, but also the inclination angle of the main frame 3 relative to the horizontal plane can be adjusted.

[0057] like Figure 3As shown, the vertical adjustment mechanism includes a transmission screw 42 rotatably mounted on a support body 41 and a slider 43 that cooperates with the transmission screw 42. The slider 43 is connected to the main frame 3. In this embodiment, the support body 41 is a rectangular frame with bearings provided on the upper and lower opposite walls of the rectangular frame. The transmission screw is mounted on the support body 41 via bearings 45. The transmission screw is driven to rotate by a manual rocker (not shown in the figure). All screws herein can be driven to rotate by the manual rocker. The slider 43 drives the main frame 3 up and down. In this embodiment, the thread of the transmission screw is a T-type thread with a locking function. The main frame 3 is locked after it moves to a set height. A support frame 44 is also provided on the outside of the fixed frame. The support frame 44 is perpendicular to the transmission screw 42. In this embodiment, the support frame 44 is a horizontal plate fixed to the outer walls of the fixed frame on opposite sides. The support frame 44 is used to support the ground bracket 8 to facilitate the connection between the main frame 3 and the vertical adjustment frame.

[0058] The first adapter frame 33 and the second adapter frame 51 have the same structure. The structure of the first adapter frame 33 is described below by taking the first adapter frame 33 as an example. Figure 4 As shown, the first adapter frame 33 includes a mounting base 331, an adjustment screw 332 rotatably mounted to the mounting base 331, and a transmission support 333 having internal threads that mate with the adjustment screw 332. In this embodiment, the mounting base 331 can slide along the longitudinal guide rail of the upper beam. The transmission support 333 is equipped with a guide rod 334, one end of which is provided with a wave-crushing plate mounting seat 336. The adjustment screw 332 also has a T-thread thread that provides a locking function. When the adjustment screw 332 rotates, the transmission support 333 drives the guide rod 334 up and down, thereby adjusting the height of the wave-crushing plate. The first adapter frame 333 also includes a guide support 335 that can slide along the longitudinal guide rail of the lower beam. The guide support 335 is equipped with a guide plate 3351 with a guide hole that allows the guide rod 334 to vertically pass through. In this embodiment, the guide support 335 is a vertical plate, the guide plate 3351 is a horizontal plate, and the axis of the guide hole is vertical to prevent the guide rod 334 from deflecting in other directions. In this embodiment, the guide support 335 and the mounting support are both provided with bearings 337, and the adjustment screw 332 is mounted to the guide support 335 and the mounting support via the bearings 337. The wave crusher mounting seat 336 includes a mounting plate 3361, a first hinge 3362 fixed to the mounting plate 3361, and a second hinge 3363 hinged to the first hinge 3362. The movable wave crusher 2 is fixed to the second hinge 3363. A single movable wave crusher 2 can rotate to a certain extent under the impact of water waves, thereby causing the entire wave crusher to deform to cushion and absorb the impact of the water waves.

[0059] After splicing, the edge of the entire wave crushing plate is fixed, and adjacent wave crushing plates are spliced ​​together by horizontal force. The spliced ​​plates can be two movable wave crushing plates 2 or two fixed wave crushing plates 1 or one movable wave crushing plate 2 and one fixed wave crushing plate 1. Figure 5 This is a schematic diagram of the first structure for splicing corrugated plates. The first structure is described by taking the splicing of two fixed corrugated plates 1 as an example. The edges of the fixed corrugated plates 1 that are spliced ​​together have a vertical splicing surface 11, and the vertical splicing surface 11 is provided with a sealing groove 12. During splicing, it is only necessary to align the sealing grooves 12 of adjacent corrugated plates to form a sealing hole. An elastic sealing tube 6 is provided in the sealing hole. The elastic sealing tube 6 is filled with compressed gas to expand the elastic sealing tube 6 and adhere to the inner wall of the sealing hole to form a seal. This structure makes splicing more convenient, and the elastic sealing tube 6 filled with compressed gas adheres to the inner wall of the sealing groove 12 to form a reliable seal. The sealing tube can be made of a polymer chemical material or rubber, preferably a rubber tube.

[0060] Figure 6 22, and the second step 22 has a first step 21 and a second step 22. The first step 21 and the second step 22 both have upward horizontal surfaces 211, 21 and vertical surfaces 212, 222 perpendicular thereto. The edge of the other of the movable wave crushing plates 2 or the fixed wave crushing plates 1 that are spliced ​​together has a third step 23. The third step 23 has a downward horizontal surface 231 and a vertical surface 232 perpendicular thereto. The first part of the horizontal surface 231 of the third step 23 cooperates with the horizontal surface 211 of the first step 21 up and down, and the second part of the horizontal surface 231 of the third step 23 and the vertical surface 232, the horizontal surface 221 and the vertical surface 222 of the second step 22 form a sealing hole. An elastic sealing tube 6 is provided in the sealing hole. The elastic sealing tube 6 is filled with compressed gas to expand the elastic sealing tube 6 and tightly adhere to the inner wall of the sealing hole to form a seal. In this embodiment, after the splicing is completed, a gap is formed in the horizontal direction between the third step 23 and the second step 22, which provides a deformation space between the two spliced ​​wave crushing plates, thereby buffering and absorbing the impact of waves.

[0061] Both structures above employ an elastic sealing tube 6, which ensures a seal between adjacent crush plates and reduces the requirements for the installation and coordination of adjacent crush plates, thereby reducing assembly requirements while ensuring a seal. The above are only specific embodiments. In practice, each crush plate, including the movable crush plate 2 and the fixed crush plate 1, may employ both the first and second structures. Of course, in the same embodiment, it is preferred to employ the same structure.

[0062] Each of the longitudinal adjustment frames 5 further includes two third adapter frames 52 that slide along the transverse guide rails and are used to connect to the ship model 7. The two third adapter frames 52 are located between the two second adapter frames 51. The two third adapter frames 52 are used to connect to the two sides of the ship model 7. Figure 7 As shown, the third adapter frame 52 includes a mounting base 521 that can slide along the transverse guide rail of the upper beam of the longitudinal adjustment frame 5, an adjustment screw 522 rotatably mounted on the mounting base 521, and a transmission support 523 with an internal thread that can cooperate with the adjustment screw 522. The thread of the adjustment screw 522 is also a T-type thread that can lock the position of the transmission support 523. The transmission support 523 is provided with a guide rod 524. The third adapter frame 52 also includes a guide support 525 that can slide along the transverse guide rail of the lower beam. The guide support 5 25 is provided with a horizontal guide plate 5251 having a guide hole with a vertical axis that allows the guide rod 524 to pass through. One end of the guide rod 524 is provided with a ship side mounting seat 526. The ship side mounting seat 526 includes a horizontal mounting plate 5264, a first hinge 5261 fixed to the mounting plate 5264, and a second hinge 5262 hinged to the first hinge 5261. The second hinge 5262 is provided with two vertical fixing plates 5263, which can clamp the ship side 71 therebetween. In this way, adjusting the vertical adjustment frame 4 can adjust the height and pitch angle of the entire ship model 7. In this embodiment, both the mounting base 521 and the guide support 525 are provided with bearings 527, and the adjustment screw 522 is mounted to the mounting base 521 and the guide support 525 via the bearings 527.
