Description

Technical Field

[0001] The invention relates to the technical field of ship engineering, and in particular to a flow diversion device based on a one-way water pool. Background Art

[0002] In the fields of ship engineering, waves, strong winds, and ocean currents are important factors controlling ship construction. Waves in the ocean are mainly wind waves and swell waves. Wind waves are waves formed under the direct action of wind. When the wind stops or when the waves leave the wind zone, the waves are called swell waves.

[0003] Under the influence of the marine environment, such as waves and currents, when the wave fluctuation period is close to the vibration period of the ship structure, it will cause a large resonance of the ship structure, and the ship structure may suffer devastating damage.

[0004] In related technologies, wind and wave tests require that the experimental physical model be placed in a one-way water pool for simulation and testing. However, when the wind and waves in the water pool are one-way waves from one end to the other, the wind and waves will directly hit the end face of the physical model, causing damage to the wave shape and making the experimental data inaccurate. Summary of the invention

[0005] The purpose of the present invention is to provide a diversion device based on a one-way water pool to solve the technical problem that the physical model will cause wave type destruction in the one-way water pool of the wind and wave test, resulting in inaccurate experimental data.

[0008] The water pool comprises a first pool bottom and two pool side plates arranged opposite to each other, wherein the two pool side plates and the first pool bottom are arranged in a U-shaped structure;

[0009] The lifting device is used to change the height of the physical model in the water pool;

[0010] One end of the flow guide device is hinged to one side of the incoming flow direction of the physical model, and the other end is slidably arranged on the first pool bottom of the pool;

[0011] When the physical model has a preset height from the first pool bottom of the water pool, the flow guiding device guides the incoming flow from the first pool bottom of the water pool to the physical model.

[0012] According to at least one embodiment of the present invention, the width of the flow guiding device is consistent with the width of the physical model.

[0013] According to at least one embodiment of the present invention, the flow guiding device comprises a flat plate, and the flat plate is a plate with a smooth surface.

[0014] According to at least one embodiment of the present invention, the guide device further comprises a frame structure arranged at the bottom of the flat plate, and the frame structure is a steel pipe welded structure.

[0015] According to at least one embodiment of the present invention, the flow guide device further comprises a walking wheel arranged at an end of the frame structure away from the physical model;

[0016] The flat plate is slidably arranged on the first pool bottom of the pool through the walking wheels.

[0017] According to at least one embodiment of the present invention, the hinge between the flow guide device and the physical model is close to the top surface of the physical model;

[0018] When the physical model is at the maximum water depth of the pool, the top surface of the physical model is flush with the top surface of the flat plate.

[0019] According to at least one embodiment of the present invention, a second pool bottom is arranged on the first pool bottom of the water pool, the second pool bottom is arranged on one side of the incoming flow direction of the physical model, and the depth of the second pool bottom relative to the first pool bottom is consistent with the thickness of the guide device.

[0020] According to at least one embodiment of the present invention, the lifting device includes one of a crane, a gantry, a hydraulic cylinder, a hydraulic cylinder, a pneumatic cylinder or a winch.

[0021] According to at least one embodiment of the present invention, the lifting device includes two lifting units, and the two lifting units are respectively arranged on both sides of the physical model;

[0022] Each lifting unit includes a winch, which is a double-drum winch connected to the physical model via two riggings.

[0023] According to at least one embodiment of the present invention, the double-drum winch is located outside the pool;

[0024] The lifting unit further comprises a first guide wheel and a second guide wheel disposed on a side plate of the pool near the top, wherein the second guide wheel is located on the inner side of the pool and the first guide wheel is located on the outer side of the pool;

[0025] One end of the rigging passes around the first guide wheel and the second guide wheel and is connected to the physical model.

[0026] Among the one or more technical solutions provided in the exemplary embodiments of the present invention, at least one of the following beneficial effects can be achieved.

Specifically, the water pool is a roughly U-shaped water pool, which has a first pool bottom and two oppositely arranged pool side panels, and the water flow and wind and waves flow from one end of the water pool to the other end, that is, the wind and waves will impact one end of the physical model, and leave the physical model from the opposite other end position. Since the height of the physical model is constantly changing during the experiment, it is inevitable that the water flow and wind and waves will impact the end face of the physical model, thereby causing the destruction of the wave type. In order to reduce the impact of the end face of the physical model on the destruction of the wave type, when the physical model has a preset height from the first pool bottom of the water pool, the flow from the first pool bottom of the water pool is directed to the physical model by a diversion device hinged on the end face of the physical model, rather than directly hitting the end face of the physical model.

[0028] Furthermore, one end of the flow guide device is hinged to one side of the incoming flow direction of the physical model, and the other end is a free end, which can be slidably arranged or overlapped on the first bottom of the pool, and the length of the flow guide device is long enough, so that no matter what height the physical model is lifted to, the flow guide device will always form an inclined surface between the physical model and the first bottom of the pool, so as to transfer the wind and waves to the top surface of the physical model through the flow guide device. Therefore, no matter what height the physical model is at, the flow guide device can play a diversion role, and the flow guide device does not require manual intervention, so that it can be easy to operate and have high experimental efficiency on the basis of improving the accuracy of experimental data.

DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Figure 1 is an axonometric structural schematic diagram of a pool according to an embodiment of the present invention; Figure 3 Schematic diagram of the axonometric structure of the lifting device and the tightening device according to the embodiment of the present invention. Figure 1 and Figure 3 As shown, in the guide device of the exemplary embodiment of the present invention, the pool has a first pool bottom 41 and two pool side plates 42 arranged opposite to each other, and the two pool side plates 42 and the first pool bottom 41 are arranged in a U-shaped structure.

[0040] The water tank and its ancillary equipment are used to simulate marine environments such as waves, strong winds, and ocean currents, thereby performing wave simulation, flow field simulation, and wind field simulation, while the physical model 20 is used to simulate cross-sea bridges, oil platforms, offshore wind power generation devices, etc. The physical model 20 undergoes structural changes based on the actual needs of the simulation object.

[0041] Specifically, the water flow and wind and waves flow from one end of the pool to the other end (the direction of the wind and waves is shown in the figure). Figure 1), that is, the wind and waves will impact one end of the physical model 20, and leave the physical model 20 from the other end. Since the height of the physical model 20 needs to be constantly changed during the experiment, the water flow and wind and waves will inevitably impact the end face of the physical model 20 head-on, thereby causing damage to the wave shape.

[0042] It can be understood that the physical model 20 is located in the middle of the water flow direction of the pool; the width of the physical model 20 is less than or equal to the distance between the two pool side panels 42.

[0043] Figure 2 is an axonometric structural schematic diagram of a lifting device according to an embodiment of the present invention; Figure 4 2 is a schematic diagram of the main structure of the first tightening unit according to an embodiment of the present invention. Figure 2-Figure 4 As described, the lifting device 30 can lift the physical model 20 to different water depths, and lock the physical model 20 at the preset height through the locking device, so that experiments in wave, strong wind and ocean current environments can be carried out stably; after the experiment is completed, the height of the physical model 20 can be further lifted or lowered by the lifting device 30 to test various performance indicators at the next preset height.

[0044] The lifting device 30 includes two lifting units, which are respectively arranged on both sides of the physical model 20. The lifting units are used to lift the physical model 20 to a preset height.

[0045] Exemplarily, the power of the lifting unit can be a crane, a gantry or a drive cylinder (electric / hydraulic / pneumatic) to provide vertical driving force. The drive cylinder in the above-mentioned power device is not easy to arrange when used to lift the physical model 20 in water and is difficult to operate for the physical model 20 that is a large equipment, while the crane and the gantry are not easy to fix and tighten the position of the physical model 20.

[0046] In the exemplary embodiment of the present invention, the power of the lifting unit is a winch. A winch is set on the ground on both sides outside the pool. The winch is a double-drum winch, which drags two riggings 31 respectively. The two riggings 31 pass through the pool side plate 42 of the pool and are connected to one side of the physical model 20. The double-drum winch can ensure the synchronous lifting of one side of the physical model 20. The double-drum winches of the two lifting units all use servo drive motors to ensure the synchronous lifting of the two winches, that is, it can ensure the synchronous lifting of both sides of the physical model 20, and the lifting process is relatively stable.

[0047] In order to make the rigging 31 be in a vertical state when connected to the physical model 20, that is, inside the pool, third grooves 421 are respectively set at positions corresponding to the rigging 31 on the pool side plates 42 of the pool, and the third grooves 421 are formed by the pool side plates 42 protruding toward the outside of the pool, wherein the first guide wheel 321 uses the outer wall surface of the groove bottom of the third groove 421 as a fulcrum, and the second guide wheel 322 uses the inner wall surface of the groove bottom of the third groove 421 as a fulcrum, and the entire second guide wheel 322 and the bracket and the corresponding part of the rigging 31 are all located in the third groove 421, that is, there is no protrusion on the inner wall surface of the pool side plates 42 of the pool, so that the physical model 20 can be smoothly lifted to the corresponding height without hindrance.

[0048] Furthermore, the third groove 421 is provided so that the rigging 31 and the second guide wheel 322 do not affect the wind and wave test area in the water pool.

[0049] The above-mentioned method of arranging winches on both sides of the pool and using the pulley and rigging 31 set in the third groove 421 is more suitable for the arrangement of the physical model 20 due to fewer components and less internal space occupied by the pool, and will not damage the water flow environment in the pool; the hoisting method using the winch and rigging 31 is applicable to both large and small physical models 20. Compared with cranes and trusses, it does not occupy too much height space, is more friendly to the construction of experimental plants, and has lower costs.

[0050] like Figure 1 As shown, the number of the third grooves 421 is four, and the third grooves 421 on different pool side plates 42 are symmetrically arranged in pairs, and the ends of the two riggings 31 of the same winch are connected to the side of the physical model 20.

[0051] like Figure 2 As shown, in the device of the exemplary embodiment of the present invention, at the top of the rigging 31 passing through the third groove 421, the first guide wheel 321 is respectively arranged on the outside and the second guide wheel 322 is arranged on the inside, wherein the rigging 31 of the second guide wheel 322 arranged on the inside is vertically connected to the physical model 20, thereby ensuring the stability of the lifting. It can be understood that the first guide wheel 321 and the second guide wheel 322 both use the wall surface of the third groove 421 as a fulcrum, and the rigging 31 from the winch is guided by the first guide wheel 321 and the second guide wheel 322 to enter the inside of the pool and is connected to the side of the physical model 20.

[0052] It should be noted that, in order to ensure the stability of the physical model 20 during the lifting process, the rigging 31 located on both sides of the pool are symmetrically arranged with respect to the physical model 20 .

[0053] Considering the lifting method using the winch and rigging 31, it is difficult for the large physical model 20 to remain stable under the impact of wind and waves. Figure 3 and Figure 4 As shown, the fastening device in the apparatus of the exemplary embodiment of the present invention includes at least one first fastening unit and at least one second fastening unit, and the first fastening unit and the second fastening unit are respectively arranged on both sides of the physical model 20.

[0054] The number of the first tightening units and the number of the second tightening units can be determined according to actual needs. Considering the stability during the lifting process, the number of the first tightening units is two, and the two first tightening units are respectively arranged at positions close to the ends of the physical model 20. The number of the second tightening units is two, and the two second tightening units are respectively arranged at positions close to the ends of the physical model 20.

[0055] In some embodiments, the first tightening unit and the second tightening unit are symmetrically arranged about the physical model 20. Specifically, a portion of the first tightening unit and a portion of the second tightening unit are both located in the corresponding third groove 421. The first tightening unit and the second tightening unit cooperate with each other to tighten the physical model 20 in different water depths.

[0056] Figure 5 is a schematic diagram of the front view structure of a flow guide device according to an embodiment of the present invention; Figure 6 Schematic diagram of the partial structure of the flow guide device according to an embodiment of the present invention. Figure 1 , Figure 5 and Figure 6 As shown, the first pool bottom 41 of the pool is provided with a second pool bottom 411 on the inflow side of the physical model 20. When the physical model 20 is located at the maximum water depth of the pool, illustratively, the hinge between the flat plate 51 and the physical model 20 is close to the top surface of the physical model 20. The top surface of the flat plate 51 is on the same horizontal plane as the top surface of the physical model 20, and the bottom surface of the flat plate 51 is attached to the second pool bottom 411 of the first pool bottom 41 of the pool.

[0057] It can be understood that in the area of ​​the pool close to the four third grooves 421, a cavity for holding the physical model 20 is also provided, and the cavity, the second pool bottom 411 and the first pool bottom 41 form a two-step step, so that when the physical model 20 is located in the cavity (when the physical model 20 is at the maximum water depth), the top surface of the physical model 20, the top surface of the flat plate 51 and the first pool bottom 41 are on the same horizontal plane.

[0058] like Figure 5 As shown, the flow guiding device of the exemplary embodiment of the present invention includes a flat plate 51 hinged to the incoming flow end of the physical model 20 , and the hinge position between the flat plate 51 and the physical model 20 is located at the top position of the physical model 20 .

[0059] Exemplarily, the flat plate 51 is a plate with a smooth surface; the width of the flat plate 51 is the same as the width of the physical model 20 , and the length of the flat plate 51 is substantially the same as the length of the physical model 20 .

[0060] In some embodiments, the guide device further includes a frame structure disposed at the bottom of the flat plate 51, and the frame structure is a steel pipe welded structure. The steel pipe welded structure is a truss-type hollow structure, which is welded vertically and horizontally, and the structure can ensure that the flat plate 51 has overall rigidity, and prevent deformation under the impact of wind and waves, thereby reducing the guide effect.

[0061] In some embodiments, the free end of the flat plate 51 can slide on the second pool bottom 411. As the physical model 20 rises, an angle is formed between the flat plate 51 and the physical model 20, and the free end of the flat plate 51 gradually moves toward the physical model 20. When wind and waves impact the side from the incoming flow direction, the wind and waves transition to the top surface of the physical model 20 through the slope of the flat plate 51, thereby preventing the wind and waves from directly hitting the side of the physical model 20 and causing wave damage.

[0062] In some embodiments, the guide device further includes a running wheel 511 disposed at one end of the frame structure away from the physical model 20; the flat plate 51 is slidably disposed on the first pool bottom 41 of the pool via the running wheel 511. The number of running wheels 511 disposed at the free end of the flat plate 51 can be adjusted according to actual needs, and the arrangement of the running wheels 511 can enable the guide device to move smoothly on the second pool bottom 411.

[0063] Considering the height difference between the second pool bottom 411 and the first pool bottom 41 of the pool, when the free end of the flat plate 51 moves toward the physical model 20 along the surface of the second pool bottom 411, the water flow on the first pool bottom 41 will directly impact the free end of the flat plate 51 and form a vortex between the flat plate 51 and the step surface.

[0064] like Figure 5 and Figure 6 As shown, the guide device of the exemplary embodiment of the present invention further includes a transition plate 52 hinged to the first pool bottom 41 of the pool. The width of the transition plate 52 is consistent with the width of the flat plate 51, and the length is determined according to actual conditions.

[0065] One end of the transition plate 52 is hinged at a position where the first pool bottom 41 and the second pool bottom 411 of the pool are adjacent, and the transition plate 52 is hinged to the first pool bottom 41 through a movable hinge, wherein a connecting plate of the movable hinge is fixed to the first pool bottom 41 of the pool, and another connecting plate is welded to the transition plate 52.

[0066] The transition plate 52 has a sufficient length, and the free end of the transition plate 52 is always overlapped on the top surface of the flat plate 51. When the flat plate 51 is tilted and displaced as the physical model 20 rises, the transition plate 52 overlapped on the flat plate 51 can form a smooth transition between the first pool bottom 41 of the pool and the free end of the flat plate 51, thereby minimizing the damage to the wave shape and ensuring the consistency and validity of the experimental data.

[0067] Since there is a relative movement process between the transition plate 52 and the flat plate 51, in order to make the process transition smoothly, a first roller 521 is set at the bottom of the free end of the transition plate 52. Optionally, one or more second rollers 522 are set in the middle part of the bottom of the transition plate 52. The transition plate 52 has a sufficient length. No matter in any position, the overlapping movement process between the transition plate 52 and the flat plate 51 can be completed by the rolling friction of the first roller 521 and the second roller 522.

[0068] Exemplarily, the first fastening unit includes a first groove member 112 , and the second fastening unit includes a second groove member 122 . The first groove member 112 and the second groove member 122 have the same structure.

[0069] In order to make the physical model 20 fit the pool side plate 42 of the pool as closely as possible and maintain the accuracy of the experimental data, two first groove members 112 and two second groove members 122 are respectively provided on both sides of the physical model 20 .

[0070] For example, two first groove members 112 are disposed on the first side of the physical model 20 and are located near the bottom of the physical model 20; two second groove members 122 are disposed on the second side of the physical model 20 and are located near the bottom of the physical model 20. The four groove members are respectively protruded from the side of the physical model 20, wherein at least a portion of the groove members is located in the corresponding third groove 421.

[0071] For example, two ear plates are arranged on the top surface of each groove member, a pin is arranged between the two ear plates, and the rigging 31 is sleeved on the pin to form a connection with the groove member.

[0072] Exemplarily, a first groove is provided on the side of each first groove member 112 facing away from the physical model 20, and the first groove extends along the vertical direction to the top and bottom surfaces of the first groove member 112; a second groove is provided on the side of each second groove member 122 facing away from the physical model 20, and the second groove extends along the vertical direction to the top and bottom surfaces of the second groove member 122.

[0073] For example, the first groove and the second groove are both wedge-shaped grooves, and the cross-section of the first groove decreases in size along the direction close to the physical model 20, that is, the first groove is in an expanding structure along the direction away from the physical model 20; the second groove is also in an expanding structure in the direction away from the physical model 20. Exemplarily, the cross-sections of the first groove and the second groove are both isosceles trapezoids and right-angled trapezoids. When the cross-sections of the first groove and the second groove are both isosceles trapezoids, the lifting process of the physical model 20 is smoother and the positioning is more accurate.

[0074] The first tightening unit also includes a first gate 111 that cooperates with the first groove member 112, one end of the first gate 111 is hinged on the ground and extends along the vertical direction; the second tightening unit also includes a second gate 121 that cooperates with the second groove member 122, one end of the second gate 121 is fixed on the ground and extends along the vertical direction.

[0075] In actual application, one end of the first gate 111 is hinged on the first pool bottom 41 of the pool and is located in the corresponding third groove 421; one end of the second gate 121 is fixed on the first pool bottom 41 of the pool and is located in the corresponding third groove 421. The first gate 111 and the second gate 121 extend along the height direction of the third groove 421 to a position near the top of the pool. A linear motion structure is also provided near the top of the third groove 421 where the first gate 111 is located, such as a hydraulic cylinder 13, a cylinder or a hydraulic cylinder 13. The following description takes the servo hydraulic cylinder 13 as an example. The telescopic end of the servo hydraulic cylinder 13 is hinged to the top of the first gate 111, and its telescopic end moves in a direction perpendicular to the pool side plate 42 of the pool.

[0076] When the physical model 20 reaches the preset height position driven by the lifting device 30, the telescopic end of the servo hydraulic cylinder 13 extends, pushing the top of the first gate 111 to move toward the inside of the pool, and the middle part of the first gate 111 is gradually pressed against the first groove of the first groove member 112, and the second groove of the second groove member 122 is also pressed against the middle part of the second gate 121. Based on this, a part of the first gate 111 is embedded in the first groove, and a part of the second gate 121 is embedded in the second groove, so that the corresponding first gate 111 and the second gate 121 cooperate to clamp the physical model 20, maintain its stability and bear lateral loads, such as Figure 1 The force shown is from the side impact of wind and waves.

[0077] When the physical model 20 needs to change the water depth in the pool, the telescopic end of the servo hydraulic cylinder 13 is shortened, driving the top of the first gate 111 to move outward from the pool, the pressing force of the first gate 111 in the first groove is reduced, and the pressing force of the second gate 121 in the second groove is also reduced, and the first gate 111 and the second gate 121 lose their grip on the physical model 20. At this time, the lifting device 30 can drive the physical model 20 to rise and fall to the corresponding water depth.

[0078] Exemplarily, the first gate 111 and the second gate 121 are plates with uniform thickness. Optionally, the first gate 111 also has a first cone 111a that cooperates with the first groove, and the second gate 121 has a second cone 121a that cooperates with the second groove, wherein the shape of the first cone 111a matches the first groove, and its cross-section is an isosceles trapezoid; the shape of the second cone 121a matches the second groove, and its cross-section is also an isosceles trapezoid.

[0079] In some embodiments, when the telescopic end of the servo hydraulic cylinder 13 is fully retracted, the first cone 111a of the first gate 111 is still within the first groove range of the first groove member 112, that is, the first gate 111 and the first groove are not completely disengaged; the second cone 121a of the second gate 121 is still within the second groove range of the second groove member 122, that is, the second gate 121 and the second groove are not completely disengaged. Therefore, when the physical model 20 needs to change the water depth in the pool, driven by the lifting device 30, the physical model 20 will still move along the first gate 111 and the second gate 121. At this time, the first gate 111 and the second gate 121 are used to guide the physical model 20, avoiding the physical model 20 from vigorous shaking due to the flexibility of the rigging 31, preventing the heavy-loaded physical model 20 from damaging the pool and related equipment, and improving the safety of the experiment.

[0080] Considering that the first gate 111 is a movable plate and a long strip plate, for example, its length can be 3m to 5m, or longer, and in order to install the second guide wheel 322 and the rigging 31 and other auxiliary components, the width of the third groove 421 of the pool is much greater than the thickness of the first gate 111, therefore, the third groove 421 of the pool cannot limit the movable first gate 111, and the first gate 111 may be misaligned during the activity due to its own rigidity. Therefore, a guide device is also provided in the third groove 421 where the first gate 111 is located, and the guide device includes a first guide unit provided on one groove wall of the third groove 421 and a second guide unit provided on another groove wall, and an activity space for the first gate 111 to move is formed between the first guide unit and the second guide unit, so as to maintain the movement accuracy of the first gate 111 and avoid deviation.

[0081] Furthermore, the first guide unit and the second guide unit are arranged on both sides of the first gate 111, which ensures that the rotation direction of the first gate 111 is always perpendicular to the vertical direction. When the physical model 20 is locked by the fastening device, the cooperation between the first guide unit and the second guide unit and the first gate 111, and the fixed arrangement of the second gate 121 on the first pool bottom 41 of the pool can bear the impact force of wind and waves from the side (such as Figure 1 Thus, the physical model 20 of the exemplary embodiment of the present invention does not tilt or shake under the impact of wind and waves, and remains stable to ensure the accuracy of the test data.

[0082] Exemplarily, the first guide unit is located on the outer side of the first gate 111 (the side where the two first gates 111 face away from each other), and the second guide unit is located on the inner side of the first gate 111 .

[0083] For example, the first guide unit is composed of a plurality of first rods 141 disposed on the wall of the third groove 421 , wherein the axial direction of the first rods 141 is perpendicular to the first gate 111 , and the plurality of first rods 141 are evenly disposed along the height direction of the wall of the third groove 421 .

[0084] The second guide unit is composed of a plurality of second rods 142 arranged on another groove wall of the third groove 421 , wherein the axial direction of the second rods 142 is parallel to the first gate 111 , and the plurality of second rods 142 are evenly arranged along the height direction of the groove wall of the third groove 421 .

[0085] In some embodiments, the first rods 141 and the second rods 142 correspond to each other one by one, and the corresponding first rods 141 and the second rods 142 are located at the same position in the height direction of the third groove 421 .

[0086] It should be noted that the axial direction of the first rod 141 is set to be perpendicular to the first gate 111. According to the movable space required by the first gate 111, the axial length of the first rod 141 can be conveniently cut to maintain a certain distance with the second rod 142. When the axial directions of the first rod 141 and the second rod 142 are parallel to the first gate 111, the distance between the first rod 141 and the second rod 142 may be too large to cause the first gate 111 to shake in the incoming flow direction, and the physical model 20 cannot be tightened, thereby causing inaccurate experimental data.

[0087] Exemplarily, the first card slot, the second card slot and the third card slot are respectively arranged on the wall surfaces opposite to the third groove 421, and the first card slot, the second card slot and the third card slot are arranged in the direction away from the physical model 20, and all extend in the vertical direction, the first card slot extends downward from the top of the third groove 421 to 2 / 3 of the height of the third groove 421; the second card slot extends downward from the top of the third groove 421 to 1 / 3 of the height of the third groove 421, and the third card slot extends downward from the top of the third groove 421 to a position near the bottom of the third groove 421.

[0088] The flow guide device also includes a third sealing member, a first sealing member and a second sealing member, wherein the two sides of the third sealing member are fixedly arranged in the corresponding first slot; the two sides of the first sealing member are slidably arranged in the corresponding second slot; and the two sides of the second sealing member are slidably arranged in the corresponding third slot.

[0089] In another optional embodiment, sliders are provided on both sides of the first sealing member and the second sealing member, and the first sealing member and the second sealing member are slidably disposed in the second clamping groove and the third clamping groove respectively through the sliders.

[0090] For example, the bottom end of the first sealing member is further provided with a first hook portion facing the second sealing member; the top end of the second sealing member is further provided with a second hook portion facing the first sealing member. The first sealing member is attached to the third sealing member, and the bottom ends of the first sealing member and the second sealing member can be arranged on the corresponding first groove member 112.

[0091] When the physical model 20 rises, it pushes the first sealing member and the second sealing member to move upward; when the physical model 20 falls, the first sealing member and the second sealing member fall under the action of gravity, and when the first sealing member falls to the lowest position, the second sealing member continues to fall until the second hook and the first hook overlap. Based on this, during the entire lifting or lowering process of the physical model 20, the opening of the third groove 421 above the bottom of the physical model 20 can be sealed by the third sealing member, the first sealing member, and the second sealing member, so that the inner wall surface of the pool side plate 42 of the pool forms a roughly complete wall surface, thereby preventing the damage of the wave shape and improving the accuracy of the experimental data.

[0092] It should be understood by those skilled in the art that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
