Description

Technical Field

[0001] This application relates to the field of experimental water tank technology, and in particular to a baffle structure for deep and shallow water tanks and an experimental water tank. Background Technology

[0002] The combined deep-shallow water tank is an experimental facility used in fields such as fluid mechanics testing, marine engineering simulation, and hydraulic research. It is spatially divided into a deep pool and a shallow pool, which work together to reproduce complex fluid interaction scenarios across depth gradients. Furthermore, by controlling the on / off states of the deep and shallow pools during experiments, it is possible to simulate independent operation of the deep and shallow pools or cross-pool flow of fluid between them.

[0003] In existing combined deep and shallow water tanks, the connection and separation are generally achieved by manually transporting or using a crane to move the partition device. Common structures for these partition devices include steel plate seats, concrete baffles, and detachable gates. Taking a steel plate seat as an example: the plate seat adopts a steel frame structure with sealing rubber strips embedded in its edges; when switching states, it is necessary to use equipment such as cranes to lift the plate seat between the deep and shallow water tanks to separate the two water tanks. After installation, the plate seat is fixed in position by its own weight.

[0004] The existing partition device suffers from low installation efficiency, requiring large hoisting equipment for state switching, which cannot meet the needs of high-frequency testing. In addition, under long-term hydrodynamic impact, the existing partition device may loosen and shift, compromising the test boundary conditions. Utility Model Content

[0053] Please see Figure 1 and Figure 2 The first aspect of this application provides a baffle structure for a deep and shallow water pool, including: a support 10, a baffle body 20 and a rotation drive 30.

[0054] Specifically, the baffle structure provided in this embodiment is applied to a test water tank having a deep water tank 1 and a shallow water tank 2. The water depth of the deep water tank 1 is greater than that of the shallow water tank 2. A support 10 is disposed on the shallow water tank. The support 10 can be a metal support, and a rotating shaft is threaded through the support 10. In application, multiple supports 10 can be provided and arranged at linear intervals, and multiple supports 10 can share the same rotating shaft. The rotary drive 30 can be a rotary motor. The output end of the rotary drive 30 is connected to the rotating shaft of the support 10, so that when the rotary drive 30 is started, it can drive the rotating shaft to rotate.

[0055] In this embodiment, the baffle body 20 is hinged to the support 10, that is, the baffle body 20 and the rotation shaft of the support 10 are fixedly connected. The output end of the rotary drive 30 is connected to the baffle body 20 through the rotation shaft. When the rotary drive 30 drives the rotation shaft to rotate, it can synchronously drive the baffle body 20 to flip, so that the baffle body 20 flips between the partitioned state and the retracted state.

[0056] In its intermediate state, the baffle body 20 stands upright between the deep pool 1 and the shallow pool 2. In its retracted state, the baffle body 20 flips to a horizontal position, allowing fluid exchange between the deep pool 1 and the shallow pool 2.

[0057] In practical applications of the test water tank, wave-generating equipment is installed at the boundary of the tank. Specifically, the wave-generating equipment can be installed at the boundary between the deep water tank 1 and the shallow water tank 2 along the first direction X and the second direction Y, and correspondingly generate waves along the first direction X and the second direction Y.

[0058] In this embodiment, the deep pool 1 and the shallow pool 2 are arranged along the first direction X. In the separated state, waves traveling along the first direction X are blocked by the baffle body 20, allowing the deep pool 1 and the shallow pool 2 to be tested separately. In the retracted state, the baffle body 20 is flipped to a horizontal position, parallel to the bottom of the shallow pool 2. At this time, waves traveling along the first direction X can be transmitted between the deep pool 1 and the shallow pool 2, enabling combined testing of the deep pool 1 and the shallow pool 2.

[0059] In this embodiment, taking a test pool with an internal dimension of 10m along the second direction Y as an example, the length direction of the baffle body 20 can be configured along the second direction Y, and the length of the baffle body 20 along the second direction Y can be close to 10m, for example, 9.9m. Filling structures such as adhesive strips can be provided on both sides of the baffle body 20 along the second direction Y, allowing the baffle body 20 to rotate while flexibly fitting against the inner wall of the test pool, thereby improving the blocking effect of the baffle body 20 in the intermediate state. It should be noted that in this embodiment, the baffle body 20 can block the main body of the wave, causing its energy to dissipate.

[0060] In this embodiment, in the intermediate state, wave-dissipating beaches can be set on both sides of the baffle body 20 to simulate the scenario where the energy of waves is absorbed by the wave-dissipating beaches in independent deep-water pool conditions or independent shallow-water pool conditions.

[0061] The deep and shallow pool baffle structure provided in this embodiment enables the control of the opening and closing of the deep pool 1 and the shallow pool 2 without relying on external large hoisting equipment. Furthermore, with the support 10 limiting the position of the baffle body 20, it avoids the risk of displacement due to wave impact, unlike existing baffle supports that rely solely on their own weight. This improves both switching efficiency and stability during the test. In addition, because the support 10 is fixed, the rotation path of the baffle body 20 is also fixed, resulting in high consistency in the position of the baffle body 20 after flipping. Compared to manually positioned and installed partition devices, this reduces installation deviations in different tests and improves the consistency of physical conditions across different tests.

[0062] In a more specific embodiment, it further includes: a bottom support base 40; the support 10 is fixed on the bottom support base 40. In the partitioned state, the baffle body 20 is perpendicular to the bottom surface of the bottom support base 40; in the retracted state, the baffle body 20 is parallel to the bottom surface of the bottom support base 40.

[0063] The bottom support 40 provides a unified load-bearing foundation for the support 10 and the baffle body 20. In practical applications, the bottom support 40 can be integrated with the pool body of the shallow water pool.

[0064] In one embodiment, the bottom support 40 is provided with a first placement area 41 and a second placement area 42; in the intermediate state, the baffle body 20 is located at the boundary between the first placement area 41 and the second placement area 42.

[0065] The first placement area 41 can serve as a wave-dissipating beach bearing area at the boundary of the shallow pool 2. The second placement area 42 can serve as a wave-dissipating beach bearing area at the boundary of the deep pool 1. The wave-dissipating beach can attenuate wave energy through its own structure to simulate wave dissipation in actual engineering, suppress eddy current generation, and reduce the impact of waves on the baffle body 20, thereby improving the stability of the baffle body 20 in the intermediate state.

[0066] In practical applications, the breakwater can be disassembled and assembled manually or mechanically. When in the retracted state, the main body 20 of the baffle is flipped to a horizontal position, at which point the breakwater can be disassembled and moved away.

[0067] In a further improved embodiment, the first placement area 41 is provided with a sink 411; the support 10 is disposed in the sink 411; in the retracted state, the baffle body 20 is located in the sink 411 and is flush with the top edge of the sink 411.

[0068] In this embodiment, the support 10 is located within the settling trough 411, which avoids the support 10 being directly exposed to the water and subjected to wave impact, thereby improving the service life of the support 10. Furthermore, in the case of combined deep and shallow water pools, the baffle body 20 can be flipped to be fully embedded in the settling trough 411 and flush with the top edge of the trough, making the bottom of the shallow water pool 2 flat and forming a single plane, avoiding the generation of bottom eddies, thereby ensuring the authenticity of wave propagation across the pool.

[0069] In one embodiment, the system further includes: a linear drive member 50 and a limiting block 60; the linear drive member 50 is disposed on the bottom support base 40; the output end of the linear drive member 50 is connected to the limiting block 60, and is used to drive the limiting block 60 to extend or retract; in the extended state, the limiting block 60 is located in the flipping path of the baffle body 20, and is used to provide support for the baffle body 20 in the partition state; in the retracted state, the baffle body 20 can flip between the partition state and the retracted state.

[0070] Specifically, in the intermediate state, the extended limiting block 60 can be located on the side of the baffle body 20 facing the shallow water pool 2; and the limiting block 60 can abut against the baffle body 20 at this time, so that the limiting block 60 can improve the resistance of the baffle body 20 to the impact of waves from the deep water pool 1, and ensure that the baffle body 20 has no displacement or tilting during the test, and the test boundary conditions are stable.

[0071] In practical applications, a stroke positioning sensor can be installed on the bottom support 40. The stroke positioning sensor can detect whether the baffle body 20 has been flipped to a vertical intermediate state. If so, the central control module used for control will then activate the linear drive 50 to prevent the limit block 60 from interfering with the flipping of the baffle body 20.

[0072] In the application, the bottom support 40 is provided with a drive chamber 43; both the rotary drive 30 and the linear drive 50 are provided in the drive chamber 43; the support 10 is provided outside the drive chamber 43; the output end of the rotary drive 30 extends outside the drive chamber 43; and the output end of the linear drive 50 extends outside the drive chamber 43.

[0073] Specifically, the output end of the rotary drive 30 is sealed to the cavity wall of the drive chamber 43 via a rotary seal. The output end of the linear drive 50 is sealed to the cavity wall of the drive chamber 43 via a linear seal. The rotary seal can be, for example, a skeleton oil seal as used in the prior art; the linear seal can be, for example, a shaft seal as used in the prior art.

[0074] In one embodiment, the bottom support 40 is provided with two drive chambers 43; the support 10 and the baffle body 20 are disposed between the two drive chambers 43; a rotary drive component 30 and a linear drive component 50 are provided in each of the two drive chambers 43.

[0075] Specifically, when the baffle body 20 is rotated, the rotary drive components 30 at both ends can be activated simultaneously. Similarly, when supported by the limit block 60, the linear drive components 50 at both ends of the baffle body 20 can be activated simultaneously, so that both ends of the baffle body 20 are supported by the limit block 60.

[0076] In one embodiment, the baffle body 20 includes a support plate 21 and a reinforcing plate 22; the support plate 21 is hinged to the support 10; the reinforcing plate 22 includes a plurality of plates and is disposed on the support plate 21; the plurality of reinforcing plates 22 intersect each other to form a grid structure.

[0077] Specifically, the support plate 21 may include two. The reinforcing plate 22 is disposed between the two support plates 21. The grid structure formed by the interlacing of multiple reinforcing plates 22 can evenly distribute the load generated by hydrodynamic impact to the entire support plate 21, avoiding local stress concentration; the rigidity of the grid structure is much higher than that of a simple frame structure, and it is not easy to bend or deform even when subjected to strong lateral pressure, and has good impact resistance and bending resistance.

[0078] The second aspect of this application provides a test water tank, including: a deep water tank 1, a shallow water tank 2, and a deep and shallow water tank baffle structure of any one of the above.

[0079] Specifically, the experimental pool provided in this embodiment also includes a breakwater; the deep and shallow pool baffle structure includes a bottom support 40; the bottom support 40 can be set in the shallow pool 2, and its top surface is provided with a first placement area 41 and a second placement area 42; the first placement area 41 and / or the second placement area 42 are used to place the breakwater. The support 10 is set in the bottom support 40, specifically in the settling groove 411 of the bottom support 40. The first placement area 41 and the second placement area 42 are respectively located on both sides of the support 10.

[0080] In existing test pools, the deep and shallow pools are generally set up independently. However, in this design, the deep pool 1 and the shallow pool 2 are interconnected. Therefore, in this embodiment, a dedicated first placement area 41 and a second placement area 42 are provided on the bottom support 40, forming a dedicated area for placing the breakwater beach to simulate its wave-damping effect on the deep and shallow pools. Furthermore, the breakwater beach can be moved to adapt to different test conditions. Specifically, in the retracted state, when the breakwater beach needs to be placed, it can be placed directly on the baffle body 20; in the intermediate state, the breakwater beach can be placed inside the settling tank 411.

[0081] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
