Description

Technical Field

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

[0002] The wave crushing plate is a large flat plate installed on the top of the inner cavity of the working section, which can be considered as the upper wall of the fluid during the working process of the working section. The wave crushing plate is usually made of metal plate or hard PVC plate. The wave crushing plate fits the waterline of the test ship model and needs to be matched according to the waterline profile of different ship models. During processing and installation, the staff will splice and install the wave crushing plate piece by piece in the cavitation water tunnel. The installation and adjustment workload is large, and the splicing and installation in the cavitation water tunnel is very inconvenient. Due to the different shapes of the ship model, when the ship model needs to be replaced, the wave crushing plate needs to be removed from the cavitation water tunnel piece by piece, and then the new wave crushing plate needs to be assembled and installed in the cavitation water tunnel piece by piece, and the position of each wave crushing plate needs to be adjusted according to the shape of the new ship model. In addition, after the wave crushing plate is installed, there will be gaps between the multiple splicing plates, which will cause water to leak from the gaps during the test, thereby causing the fluctuation of the water surface to affect the uniformity of the flow field.

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

[0051] The shape of the fixed wave crushing plate 1 is generally rectangular, and the fixed wave crushing plate 1 is fixed to the top of the working section of the cavitation water tunnel and is parallel to the horizontal plane. When the ship model 7 is replaced, the fixed wave crushing plate 1 can be left in the cavitation water tunnel without replacement. One end of the movable wave crushing plate 2 is cut according to the water surface line of the ship model 7 to form a shape that matches the water surface line of the ship model 7, and the other end is used to form a sealed splice with other movable wave crushing plates 2 and fixed wave crushing plates 1, and can adopt a conventional plane 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 frame 33 is used to connect the active wave crushing plate 2. The position of the active wave crushing plate 2 can be adjusted along the longitudinal guide rail by the first adapter frame 33 until the cut shape of the active wave crushing plate 2 fits the water surface line of the ship model 7. The vertical adjustment frame 4 includes a bracket body 41 for fixedly connecting with 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, and the vertical adjustment mechanism is connected 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 respectively located on both sides of the ship model 7. The second adapter frame 51 is used to connect the movable wave crushing plate 2.

[0053] When the ship model 7 needs to be replaced, the wave crushing plate device for the cavitation water tunnel test 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 together, replace the new movable wave crushing plate 2, adjust its height and horizontal position, and then move the whole 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 the 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 to the movable wave crushing plate 2 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, including two parallel longitudinal frames 31 and two parallel transverse frames 32. In this embodiment, the main frame 3 also includes a plurality of transverse reinforcement frames 34, one end of each transverse reinforcement frame 34 is fixed to one of the longitudinal frames 31, and the other end is fixed to another longitudinal frame 31, so as to strengthen the main frame 3. The plurality of transverse reinforcement frames 34 divide the main frame 3 into a plurality of areas arranged longitudinally. The longitudinal frame 31, the transverse frame 32, the longitudinal adjustment frame 5 and the longitudinal reinforcement frame 34 all include an upper beam, a lower beam, a vertical beam and an oblique beam, forming a plurality of triangular structures, so that it has stable mechanical properties. In this embodiment, the upper beam and the lower beam of each longitudinal frame 31 are provided with a set of longitudinal guide rails, and a set of longitudinal guide rails includes an inner longitudinal guide rail 312 located on the inner side of the upper beam or the lower beam and an outer longitudinal guide rail 311 located on the outer side of the upper beam or the lower beam, and the height of the two guide rails of a set of longitudinal guide rails is the same. A plurality of first adapter frames 33 constitute a plurality of 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, and the set of transverse guide rails includes 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 the second adapter frames 51, and the two groups of the 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 the support body 41 and a slider 43 matched with the transmission screw 42, and the slider 43 is connected to the main frame 3. In this embodiment, the support body 41 is a rectangular frame, and the upper and lower opposite walls of the rectangular frame are provided with bearings. The transmission screw is installed on the support body 41 through a bearing 45, and the transmission screw is driven to rotate by a manual rocker (not shown in the figure). The screws hereinafter can be driven to rotate by the manual rocker, and the slider 43 will drive the main frame 3 to move up and down. In this embodiment, the thread of the transmission screw is a T-type thread, which has a locking function, and the main frame 3 will be locked after moving to a set height. A support frame 44 is also provided on the outside of the fixed frame, and 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 wall of the opposite sides of the fixed frame. The support frame 44 is used to support on the ground bracket 8, which is convenient for connecting 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 rod 332 rotatably mounted on the mounting base 331, and a transmission support 333 having an internal thread that can cooperate with the adjustment screw rod 332. In this embodiment, the mounting base 331 can slide along the longitudinal guide rail of the upper beam, and the transmission support 333 is provided with a guide rod 334, and one end of the guide rod 334 is provided with a wave pressing plate mounting seat 336. The thread of the adjustment screw rod 332 is also a T-type thread, which has a locking function. When the adjustment screw rod 332 rotates, the transmission support 333 drives the guide rod 334 to move up and down, thereby adjusting the height of the wave pressing plate. The first adapter frame 33 also includes a guide support 335 that can slide along the longitudinal guide rail of the lower beam. The guide support 335 is provided with a guide plate 3351, and the guide plate 3351 has a guide hole that allows the guide rod 334 to pass vertically. 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 installed on the guide support 335 and the mounting support through the bearings 337. The wave crushing plate 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, and the movable wave crushing plate 2 is fixed to the second hinge 3363. A single movable wave crushing plate 2 can produce a certain degree of rotation under the impact of water waves, so that the entire wave crushing plate is deformed to buffer and absorb the impact of water waves.

[0059] After splicing, the edge of the entire wave crushing plate is fixed, and the adjacent wave crushing plates are spliced ​​together by horizontal force. The spliced ​​plates may 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 of the splicing of wave crushing plates. The splicing of two fixed wave crushing plates 1 is used as an example to describe the first structure. The edges of the fixed wave crushing 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. When splicing, it is only necessary to align the sealing grooves 12 of adjacent wave crushing 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 to fit tightly against the inner wall of the sealing hole to form a seal. This structure makes splicing more convenient, and at the same time, the elastic sealing tube 6 filled with compressed gas fits tightly against 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 The schematic diagram of the second structure of the splicing of wave crushing plates is shown. The second structure is described by taking the splicing of two movable wave crushing plates 2 as an example. The edge of one of the mutually spliced ​​movable wave crushing plates 2 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 mutually spliced ​​movable wave crushing plates 2 or the fixed wave crushing plates 1 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 between the third step 23 and the second step 22 in the horizontal direction, which provides a deformation space between the two spliced ​​wave crushing plates, and can buffer and absorb the impact of waves.

[0061] The elastic sealing tube 6 is adopted in both structures to ensure the sealing between adjacent wave crushing plates and reduce the installation and matching requirements of adjacent wave crushing plates, that is, the assembly requirements can be reduced while ensuring the sealing. The above are only specific embodiments. In fact, each wave crushing plate including the movable wave crushing plate 2 and the fixed wave crushing plate 1 may adopt the first structure and the second structure. Of course, in the same embodiment, it is best to use the same structure.

[0062] Each of the longitudinal adjustment frames 5 further includes two third adapter frames 52 sliding along the transverse guide rails for connecting to the ship model 7, and the two third adapter frames 52 are located between the two second adapter frames 51, and 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 rod 522 that can be rotatably mounted on the mounting base 521, and a transmission support 523 with an internal thread that can cooperate with the adjustment screw rod 522. The thread of the adjustment screw rod 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, the guide plate 5251 has 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, and the two fixing plates 5263 can clamp and fix the ship side 71 between them. 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, the mounting base 521 and the guide support 525 are both provided with bearings 527, and the adjustment screw 522 is installed on the mounting base 521 and the guide support 525 through the bearing 527.
