Description

Technical Field

[0001] This invention relates to the field of ship and marine engineering model testing technology, specifically to a buoyancy-assisted model pool space partitioning and water depth adjustment device. Background Technology

[0002] Model tanks are important experimental facilities used in ship and ocean engineering experiments to simulate actual coastal environments and marine conditions. They play an irreplaceable role in research on ship hydrodynamic performance, the stress on marine structures, and ice-covered engineering. Due to the diverse needs of experiments, model tests often require simulating different water depths to reflect the complex characteristics of shallow water, transitional depths, and deep water in actual sea areas.

[0003] Existing model water tanks typically adjust water depth by increasing or decreasing the water volume. This method requires frequent water addition and submersion, which is not only time-consuming and inefficient in experimental preparation, but also leads to significant water waste, hindering experimental continuity and resource conservation. Furthermore, in ice-water tank experiments involving freezing, the water depth is usually designed to be relatively large. Given water's high specific heat capacity, excessive depth significantly prolongs the freezing time, increases the operating time of the refrigeration system and energy consumption, and reduces the energy efficiency of the ice-water tank experiment. Therefore, achieving efficient water depth adjustment in model water tanks while ensuring the realism and applicability of the model experiments, and reducing water and energy consumption, has become a pressing technical problem in the field of model water tank experiments.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] This invention provides a buoyancy-assisted model pool space division and water depth adjustment device, which is mainly designed to enable rapid adjustment and stable control of the effective water depth under different test conditions without frequently increasing or decreasing the water volume in the pool. This reduces water waste, improves test preparation efficiency, shortens freezing time and reduces energy consumption in ice water pool freezing experiments, and ensures the smooth conduct and safe operation of model tests.

Positioning module: Connects with the mobile frame module to fix the mobile frame module inside the model pool.

[0007] This invention uses a combination of a movable frame module and a partition module to divide the space inside the model water tank.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] To more clearly illustrate the technical solutions in this invention, specific embodiments are described below.

[0024] Example 1 like Figures 1-5 As shown, this invention provides a buoyancy-assisted model pool space partitioning and water depth adjustment device. This device is installed inside the model pool and includes a moving frame module 2, a partitioning module 3, and a positioning module 4. The moving frame module 2 is horizontally positioned inside the model pool, and the partitioning module 3 is positioned inside the moving frame module 2. The partitioning module 3 divides the interior of the model pool, and the positioning module 4 positions the moving frame module 2, thus partitioning the model pool and enabling rapid changes in effective water depth. Simultaneously, it reduces heat exchange between the upper and lower water sections, providing convenience and safety for model experiments. This solves the problems of cumbersome, inefficient, and wasteful water depth adjustment operations in existing technologies when simulating marine environments at different depths.

[0025] In this embodiment, the movable frame module 2 is a square frame, which includes crossbeams and longitudinal beams 23. Specifically, it includes two crossbeams and two longitudinal beams 23, wherein the two crossbeams are parallel and the two longitudinal beams 23 are parallel. The ends of the two crossbeams and the two longitudinal beams 23 are welded together to form a square frame. Specifically, the crossbeams and longitudinal beams 23 are perpendicular to each other.

[0026] The main slide rails 24 are provided on the longitudinal beams 23. Specifically, the main slide rails 24 are located inside the longitudinal beams 23, and both longitudinal beams 23 have main slide rails 24. The main slide rails 24 adopt a C-shaped cross-section structure and are made of stainless steel. The partition module 3 is set inside the main slide rail 24. By sliding the partition module 3 within the main slide rail 24, the partition module 3 unfolds and divides the simulated water tank 1.

[0027] In this embodiment, the partition module 3 includes at least one partition plate, wherein the two ends of the partition plate are disposed on the movable frame module 2. Specifically, the partition plate is disposed within the main slide rail 24 opened on the movable frame module 2. The partition plate slides within the main slide rail 24 to unfold and partition the simulated water pool 1.

[0028] Meanwhile, the partition plate is a hollow partition plate with a water inlet and a water outlet. Both the water inlet and the water outlet are connected by water pipes. Water is injected into the partition plate through the water inlet and drained through the water outlet, which changes the buoyancy of the partition plate and adjusts its position in the model pool.

[0029] Specifically, the partition includes an edge partition 30 and at least one middle partition 31. To better describe the position and connection relationship between the edge partition 30 and the middle partition 31, in this embodiment, the middle partition 31 located at the outermost edge (away from the edge partition 30) is referred to as the fixed partition 32. The crossbeams include a first crossbeam 21 and a second crossbeam 22. The fixed partition 32 is fixedly connected to the second crossbeam 22 via a pivot. The fixed partition 32 is connected to the middle partition 31, adjacent middle partitions 31, and the middle partition 31 is connected to the edge partition 30 via pivots. When the water tank does not need to be separated, the edge partition 30, the middle partition 31, and the fixed partition 32 are stacked. When the water tank needs to be separated, the edge partition 30 is pulled, and the edge partition 30 drives the middle partition 31 and the fixed partition 32 to slide and unfold along the main slide rail 24 to simulate the separation of the water tank 1.

[0030] Specifically, the rotating shaft includes a joint shaft 35 and a rotation shaft 36. Starting with the edge partition 30, the intermediate partitions 31 connected to the edge partition 30 are sequentially designated as the first intermediate partition, the second intermediate partition, and so on. The joint shaft 35 is located at the end of the edge partition 30 furthest from the first intermediate partition. The other end of the edge partition 30 is rotatably connected to one end of the first intermediate partition via the rotation shaft 36. The other end of the first intermediate partition is connected to one end of the second intermediate partition via the joint shaft 35, and so on. The lengths of the middle partition 31, edge partition 30, and fixed partition 32 need to be set according to the length of the model pool and longitudinal beam 23. This ensures that one end of the fixed partition 32 is connected to the middle partition 31 through the rotating shaft 36, and the other end of the fixed partition 32 is rotatably fixed on the second crossbeam 22 through the rotating shaft 36 (or joint shaft 35). Of course, in actual operation, the middle partition 31, edge partition 30, and fixed partition 32 are the same partition. The separate naming of these partitions is only for better description of the structure of the present invention.

[0031] In order not to affect the unfolding and folding of the middle partition 31, in this embodiment, sliders are provided at both ends of the joint pivot 35. The two sliders are respectively set in the main slide rail 24, and the joint pivot 35 can slide along the main slide rail 24 as the middle partition 31 unfolds and folds. The length of the pivot 36 is less than or equal to the length of the middle partition 31 and less than or equal to the length between the two main slide rails 24.

[0032] Meanwhile, in this embodiment, a positioning post 34 and a traction hole 33 are provided at one end of the edge partition 30. The edge partition 30 is moved by the traction rope in the traction hole 33. Two positioning posts 34 are provided symmetrically on one end of the edge partition 30 for structural positioning after unfolding.

[0033] To better achieve structural positioning, a fixed column 27 is provided on the first crossbeam 21. The fixed column 27 and the positioning column 34 are fixed to each other by the fixing clip 26, so as to achieve stability of the edge partition 30, the middle partition 31 and the fixed partition 32 in the unfolded state, thereby forming a stable water tank partition structure.

[0034] Meanwhile, for ease of use, the drain outlet of the edge partition 30 is connected to the water inlet of the first middle partition via a connecting water pipe 37, the drain outlet of the first middle partition is connected to the water inlet of the second middle partition via a connecting water pipe 37, and so on, until it is connected to the water inlet of the fixed partition 32. The connecting water pipe 37 at the outlet of the fixed partition 32 is provided with an outlet, and the connecting water pipe 37 at the water inlet of the edge partition 30 is provided with an inlet. In this way, the edge partition 30, the middle partition 31 and the fixed partition 32 can be connected in series via the connecting water pipe 37. The water volume in the edge partition 30, the middle partition 31 and the fixed partition 32 can be adjusted uniformly through the inlet 38 and the outlet 39 (which can be adjusted by a water pump or other equipment), thereby controlling the overall buoyancy of the edge partition 30, the middle partition 31 and the fixed partition 32 and adjusting the vertical position of the whole device in the model pool. It is important to note that during the adjustment process, attention should be paid to the amount of water being changed. While adjusting the amount of water in the edge partition 30, the middle partition 31, and the fixed partition 32, attention should also be paid to the buoyancy in the edge partition 30, the middle partition 31, and the fixed partition 32. Careful observation is necessary to ensure that the buoyancy adjustment does not cause the edge partition 30, the middle partition 31, and the fixed partition 32 to deviate from the target position.

[0035] To ensure the stability of the vertical movement of the entire device within the model pool, in this embodiment, a guide 25 is welded at the connection between the crossbeam and the longitudinal beam 23 to guide the vertical movement of the entire device within the model pool, thereby ensuring stability during the lifting process.

[0036] This embodiment also includes a positioning module 4, which is located between the crossbeam / longitudinal beam 23 and the wall of the model pool, and is used to lock and fix the entire device after reaching the predetermined water depth.

[0037] The positioning module 4 includes a depth fixing pin 41, which is made of polyurethane (PU) elastomer material. The depth fixing pin 41 is CNC machined to form an insertion guide ramp 42, anti-slip texture 43, lifting hole 44, and positioning hole 45. The guide ramp 42 is located at the lower end of the depth fixing pin 41. The anti-slip texture 43 is evenly distributed on the depth fixing pin 41. The lifting hole 44 and positioning hole 45 are both located at the upper end of the depth fixing pin 41 for lifting and positioning the depth fixing pin 41.

[0038] To further enhance the understanding of the present invention, the following specific operating steps are provided in this embodiment: First, when it is necessary to divide the simulated water tank 1, the edge partition 30 is pulled by the traction rope in the traction hole 33. The edge partition 30 drives the middle partition 31 and the fixed partition 32 to unfold. After it is fully unfolded, the positioning post 34 on the edge partition 30 is fixed to the fixed post 27 on the first crossbeam 21 by the fixing clip 26. Next, the water volume inside the edge partition 30, middle partition 31, and fixed partition 32 is adjusted through the water inlet 38 and the water outlet 39: water is injected into the edge partition 30, middle partition 31, and fixed partition 32 through the water inlet 38 to increase the overall weight, causing the edge partition 30, middle partition 31, and fixed partition 32 to move downwards; the water inside the edge partition 30, middle partition 31, and fixed partition 32 is discharged through the water outlet 39 to reduce the overall weight, thereby achieving the adjustment of the overall vertical position in the model pool; After being adjusted to the appropriate position, the guide ramp 42 of the depth fixing pin 41 is installed facing the first crossbeam 21 and / or the second crossbeam 22 and / or the longitudinal beam 23 between the first crossbeam 21, the second crossbeam 22, the longitudinal beam 23 and the pool wall of the model pool. At the same time, the anti-slip texture 43 provides friction after fixing. The lifting hole 44 is used to remove the depth fixing pin 41 when in use, and the positioning hole 45 is used to achieve stable positioning. When the water depth needs to be adjusted again, the depth fixing pin 41 can be removed by lifting hole 44, and the above operation can be repeated.

[0039] The beneficial effects of this invention are as follows: 1. This invention uses partition plates to reasonably divide the test water area of ​​the model water tank and implement water depth control, so that the model test can quickly construct different water depth conditions without changing the overall water storage capacity of the water tank, significantly shortening the test preparation time and improving the efficiency of test organization and implementation. 2. This invention can effectively reduce water consumption caused by frequent water release and water addition operations, and has a good water-saving effect; 3. This invention uses partition plates to divide the model water tank. In the ice water tank freezing test application, by reducing the effective water depth, the volume of water participating in the freezing process is reduced, thereby shortening the freezing formation cycle, reducing the running time of the refrigeration system and power consumption, and improving energy utilization efficiency. 4. This invention can keep the water level relatively stable, which facilitates the arrangement, manipulation and observation of the test model by the test personnel, improves the test operation conditions, and further enhances the safety, stability and adaptability of the model pool test to various test conditions.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. The present invention is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of the present invention should be considered to fall within the protection scope of the present invention.
