Description

Technical Field

[0001] This application relates to the field of marine environment simulation technology, and in particular to a double-sided flow-generating deep-water test pool system. Background Technology

[0002] With the development of underwater vehicles, marine engineering equipment, and marine environmental sensing devices, the demand for simulating complex water flow environments in laboratories is constantly increasing.

[0003] Existing flow generation systems typically create an environment for testing water flow by installing flow-generating pumps and flow-guiding components within a water tank, in order to meet experimental requirements such as model resistance and attitude control. Consequently, during testing with existing flow generation systems, the variables that can be adjusted are generally fluid parameters such as direction, flow rate, and velocity, limiting the range of experimental scenarios that can be simulated.

[0004] In addition, in order to meet different types of experimental needs, existing laboratories often need to configure and use multiple flow generation systems, which are costly to configure and difficult to coordinate in a unified manner among multiple systems. Summary of the Invention

[0020] Furthermore, the circulation mode includes a three-pump mode;

[0021] In the three-pump mode, the first pump group, the second pump group, and the third pump group are activated.

[0024] The width of the second test area along the first direction is greater than the width of the third test area along the first direction.

[0025] Furthermore, the diverter block is movable along the first direction and is disposed at the end of the second test area.

Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0057] Please see Figure 1This application provides a dual-sided flow-generating deep-water test pool system, comprising: a pool body 10, a flow-diverting component 20, a pump component 30, and a control component 40. The pool body 10 is configured as a single large pool capable of accommodating test water and the model to be tested, and is configured to meet the water depth and horizontal space requirements for testing underwater vehicle models, marine engineering equipment models, or underwater sensing devices.

[0058] Within the pool body 10, a first test zone 11, a second test zone 12, and a third test zone 13 are arranged sequentially along a planar direction. Specifically, the first test zone 11, the second test zone 12, and the third test zone 13 can be arranged along... Figure 1 The three test zones are arranged sequentially along the X-axis, and the X-axis direction will be referred to as the first direction below. In this embodiment, the three test zones are functional test areas within the same pool body and can be located in the same circulating water body. The three test zones can be directly connected, or the water can be connected through the diversion component 20 and the corresponding flow guiding path, so that the water in the pool body 10 can circulate between different test zones.

[0059] In one implementation, the first test area 11 and the third test area 13 are located on both sides of the second test area 12, making the second test area 12 the central test area. The first test area 11 and the third test area 13 can be used as separate test areas, or they can work together with the second test area 12 to form two test areas that provide lateral incoming flow, return flow, or disturbed incoming flow.

[0060] In this embodiment, the diversion component 20 includes a diversion block 21 disposed at at least one end of the second test zone 12. For example, the diversion block 21 may be disposed in the end region of the second test zone 12 along the water flow circulation direction. When the water flow in the second test zone 12 flows toward the diversion block 21, the water flow can be guided to the first test zone 11 and the third test zone 13 respectively under the action of the diversion block 21. Specifically, the diversion block 21 has a first guide surface facing the first test zone 11 and a second guide surface facing the third test zone 13. When the water flow impacts or approaches the diversion block 21, part of the water flow enters the first test zone 11 along the first guide surface, and another part of the water flow enters the third test zone 13 along the second guide surface, thereby forming a flow path that diverts from the central region to the two side regions within a pool.

[0061] The pump assembly 30 includes a first pump group 31 disposed in a first test zone 11, a second pump group 32 disposed in a second test zone 12, and a third pump group 33 disposed in a third test zone 13. The first pump group 31 is used to drive water movement within the first test zone 11; the second pump group 32 is used to drive water movement within the second test zone 12; and the third pump group 33 is used to drive water movement within the third test zone 13. Each pump group may include one or more pumps, and the output direction of the pumps may be a second direction, i.e. Figure 1The Y-axis direction in the pump set. A bidirectional pump capable of changing the water delivery direction can be used.

[0062] The control component 40 is electrically connected to the first pump group 31, the second pump group 32, and the third pump group 33, respectively, and is used to control the number of pump groups 31, 32, and 33 that are started and their output direction according to the operating conditions. In this embodiment, the control component 40 may include a controller, a driver, a human-machine interface terminal, and a power supply module. Operators can use the control component 40 to select test conditions and control the number of pump groups started, their starting sequence, their running direction, and their output power. Therefore, different types of water flow environments can be created in the same pool 10 without replacing the entire equipment.

[0063] In this embodiment, multiple test areas, flow diversion components 20, and multiple independently controlled pump sets are integrated into the same deep-water test pool. This allows the solution to form a circulating flow by utilizing the connectivity between the second test area 12, the first test area 11, and the third test area 13. On the other hand, it can change the flow field type by utilizing different operating combinations of the three pump sets. This reduces the need to build independent pools or independent flow generation systems for different test scenarios, improves the overall utilization rate of the test facilities, and reduces the scheduling difficulty for conducting tests under different operating conditions.

[0064] In a more specific embodiment, the control component 40 is configured with one or more operating modes, including circulation mode and convergence mode. Specifically, the control component 40 can pre-store the pump set start / stop status, running direction, and operating power parameters corresponding to different operating conditions. When the test personnel select the target operating condition, the control component 40 controls the corresponding pump set to work according to the corresponding parameters, and can adjust the pump set operating status during the test.

[0065] In circulating mode, the control component 40 controls the start-up of several pump groups among the first pump group 31, the second pump group 32, and the third pump group 33, and avoids the convergence of opposing flows by controlling the output direction of the pump groups, thereby forming a stable circulating flow. For example, controlling the start-up of the first pump group 31 and along... Figure 1 The output moves from left to right, simultaneously controlling the second pump group 32 to start and move along... Figure 1 The output moves from right to left, and a stable clockwise circulation can be formed in the first test zone 11 and the second test zone 12.

[0066] As one implementation method, the circulation mode includes a single-pump mode. In the single-pump mode, the control component 40 controls the start-up of any one of the three pump groups: the first pump group 31, the second pump group 32, and the third pump group 33, and only one pump group is started, while the other pump groups are stopped or in a non-active flow-generating state. For example, when only the second pump group 32 is controlled, a relatively stable central region flow can be formed in the second test zone 12. This flow can flow into the first test zone 11 and the third test zone 13 to form a circulation, which can be used for conventional downstream tests, upstream tests, or basic resistance tests. When only the first pump group 31 or the third pump group 33 is controlled, a local circulating flow or a local turbulent flow can be formed in the corresponding two adjacent test zones. The control logic of the single-pump mode is simple, can provide a basic test flow field under low energy consumption conditions, and is also convenient for individual calibration of the flow-generating performance of different test zones.

[0067] Furthermore, in the embodiment where the pump group consists of multiple pumps arranged in an array along a first direction, the pump group can generate a biased water flow by controlling the number of pumps activated according to the control component. For example, when all pumps in the second pump group 32 are started at the same power, the water flow in the second test zone 12 will be relatively evenly distributed to the first test zone 11 and the third test zone 13, forming two relatively equal circulations. When the pumps in the second pump group 32 are started at different power levels, for example, the pumps closer to the first test zone 11 are configured with higher power, the water flow velocity in the second test zone 12 closer to the first test zone 11 will be higher, thus forming two unequal circulations. The same applies when the number of pumps started on both sides of the second pump group 32 is unequal; for example, if more pumps are started on the side closer to the first test zone 11 and fewer pumps are started on the side closer to the third test zone 13, two unequal circulations can also be formed.

[0068] As one implementation, the circulation mode includes a dual-pump mode. In dual-pump mode, the control component 40 controls the operation of two adjacent pump sets. For example, the first pump set 31 and the second pump set 32 ​​are started simultaneously while the third pump set 33 is stopped, or the second pump set 32 ​​and the third pump set 33 are started simultaneously while the first pump set 31 is stopped.

[0069] In situations where starting the second pump group 32 alone does not meet the flow requirements, the dual-pump mode can increase the flow rate in the test area, thereby improving its applicability to different operating conditions. Taking the starting of the first pump group 31 and the second pump group 32 in dual-pump mode as an example, both the first test area 11 and the second test area 12 can generate pump-driven water flow, allowing both to be used as test areas while meeting the flow requirements.

[0070] It should be noted that while the first test zone 11 and the second test zone 12 form a circulation (hereinafter referred to as the first circulation), part of the water flow in the second test zone 12 will be diverted to the third test zone 13 under the action of the diversion component 20, so that the second test zone 12 and the third test zone 13 also form a circulation (hereinafter referred to as the second circulation). In this mode, the flow rate of the first circulation is greater than that of the second circulation, which creates a transverse velocity gradient region in the second test zone 12. Therefore, while model tests can be conducted in the second test zone 12, it can also be used to study the influence of the transverse velocity gradient on the model.

[0071] As one implementation method, the circulation mode includes a three-pump mode. In the three-pump mode, the control component 40 controls the simultaneous activation of the first pump group 31, the second pump group 32, and the third pump group 33. The three pump groups can use the same or different output power. For example, the second pump group 32 is used to form the mainstream transport zone in the central area, while the first pump group 31 and the third pump group 33 are used to form supplementary or disturbed inflows on both sides, resulting in a complex flow field in the second test area 12 where the mainstream and the influences from both sides work together. The three-pump mode can be used to simulate test scenarios such as multi-regional flow coupling, complex inflows in port or strait areas, and vehicles crossing flow field boundaries, thereby increasing the complexity and adjustability of the test flow field and supporting the completion of various comprehensive flow field tests in the same pool.

[0072] In the confluence mode, the control component 40 controls the first pump group 31 and the third pump group 33 to start, and the output directions of the first pump group 31 and the third pump group 33 are the same, so that the first test zone 11 and the third test zone 13 can respectively send water flow into the second test zone 12, so as to form a symmetrical double-sided confluence flow field or an asymmetrical double-sided confluence flow field in the second test zone 12. Specifically, in the confluence mode, the second test zone 12 forms a flow field in which water flows back from both sides to the center when the second pump group 32 is stopped.

[0073] It should be noted that in the confluence mode, the second pump group 32 can be selectively turned on or off as needed, depending on the flow field scenario to be simulated.

[0074] When the control component 40 makes the output directions of the first pump group 31 and the third pump group 33 the same and the output power the same, the second test area 12 can form a symmetrical double-sided confluence flow field.

[0075] When the control component 40 sets the output directions of the first pump group 31 and the third pump group 33 to be the same, but their output powers are different—for example, setting the output power of the first pump group 31 to be greater than that of the third pump group 33—the inflow intensities on both sides of the second test zone 12 will be different. The confluence area in the second test zone 12 will shift towards the side with the weaker inflow, thus forming an asymmetric double-sided confluence flow field. This flow field can simulate real water environments such as inconsistent inflow intensities on both sides of a strait and different flow intensities on both sides of an island or reef.

[0076] In practical applications, under the confluence mode, the control component 40 can continuously adjust the output power difference between the first pump group 31 and the third pump group 33. When the power difference is small, the second test zone 12 exhibits a relatively gentle lateral velocity change; when the power difference increases, the degree of offset and shear in the confluence region increases accordingly; when the direction or intensity of the incoming flow on at least one side changes dynamically, a confluence shear zone and / or a lateral velocity gradient zone can also be formed. Through the above implementation process, this application can provide confluence, offset, shear, and abrupt flow conditions that are difficult to obtain in a traditional single stable flow field, making the test platform more suitable for model testing in complex marine environments.

[0077] Specifically, when there is a velocity difference between the incoming flows on both sides of the second test zone 12, a convergence shear zone can be formed at their confluence boundary; when the confluenced water flows undergo local deflection or backflow, a local vortex zone can be formed; when there is a significant change in the water flow velocity at adjacent positions along the first direction within the second test zone 12, a transverse velocity gradient zone can be formed; when the disturbance generated by the confluence of the two water flows acts together with the original circulating flow or local backflow within the pool, a disturbance superposition zone can be formed. The control component 40 can also change the position, range, and disturbance intensity of the aforementioned confluence area by adjusting or dynamically changing the starting power of the first pump group 31 and the third pump group 33 in stages, thereby obtaining test water flow environments of different complexities, making the system more suitable for conducting simulation tests of the anti-disturbance capabilities and attitude adjustment capabilities of different equipment under complex water flow environments.

[0078] In other embodiments, the confluence mode includes a countercurrent confluence mode. In the countercurrent confluence mode, the control component 40 controls the first pump group 31 and the third pump group 33 to start and the second pump group 32 to stop, and the output directions of the first pump group 31 and the third pump group 33 are opposite, so that the water flow from the first test area 11 and the water flow from the third test area 13 converge countercurrently in the second test area 12. Since the two water flows move in opposite directions, a convergence shear or a strong lateral velocity gradient region can be formed in the convergence area. Furthermore, by adjusting the output power of the first pump group 31 and the third pump group 33, the countercurrent convergence position and the intensity of local disturbance can also be changed. The countercurrent confluence mode can form a convergence environment of adjacent water flows with opposite directions in the same test platform, thereby reproducing actual complex hydrodynamic scenarios such as shear zones between adjacent opposite ocean currents or tidal currents, thereby further improving the simulation capability of the system.

[0079] In one embodiment, pump sets can be installed on both sides of the pool 10 along the second direction. Specifically, first pump sets 31 are installed on both sides of the first test area 11. Two second pump sets 32 are installed on both sides of the second test area 12. Two third pump sets 33 are installed on both sides of the third test area 13. The two pump sets on both sides along the second direction can be configured with different orientations to achieve bidirectional flow generation.

[0080] In one implementation, the pump body in each pump group can be a bidirectional pump; generally, a bidirectional pump can deliver in both forward and reverse directions, and the forward delivery direction is the commonly used direction of a bidirectional pump.

[0081] In this embodiment, the two sides of the pool body 10 along the second direction are referred to as the left pump group and the right pump group, respectively. That is, the first pump group 31, the second pump group 32, and the third pump group 33 all include a left pump group and a right pump group. When using a bidirectional pump, the left pump group and the right pump group can be configured such that their common directions are opposite, so that the quality of the flow field formed during forward flow generation and reverse flow generation is similar.

[0082] In one embodiment, the width of the second test area 12 along the first direction is greater than the width of the first test area 11 along the first direction; the width of the second test area 12 along the first direction is greater than the width of the third test area 13 along the first direction.

[0083] In this embodiment, the second test zone 12 serves as the central flow-generating area, providing a large flow field space. The wider second test zone 12 can accommodate underwater vehicle models or other testing equipment, and offers ample space for the convergence, development, and measurement of water flows from both sides, thereby improving the observability and measurability of the complex flow field formation process. This also helps reduce the overall construction space requirements of the pool.

[0084] In one embodiment, the diversion block 21 is movable along a first direction and disposed at the end of the second test area 12.

[0085] Specifically, the end area of ​​the second test zone 12 may be provided with a guide rail, a detachable connecting seat or other installation structure that can adjust the position of the diverter block 21. The diverter block 21 is installed in the corresponding position by sliding connection or detachable fastening connection.

[0086] During use, the test personnel can adjust the position of the diverter block 21 relative to the end of the second test zone 12 according to the test conditions. When the diverter block 21 is located in the center relative to the second test zone 12 along the first direction, the flow space on both sides of the diverter block 21 leading to the first test zone 11 and the third test zone 13 is roughly equal, allowing the water flowing from the second test zone 12 to the diverter block 21 to be distributed relatively evenly to the first test zone 11 and the third test zone 13. When the diverter block 21 moves towards the first test zone 11 along the first direction, the flow space between the diverter block 21 and the first test zone 11 decreases, and correspondingly, the flow space between the diverter block 21 and the third test zone 13 increases. The opposite occurs when the diverter block 21 moves towards the third test zone 13 along the first direction.

[0087] In this embodiment, without the need to build an additional pool 10, the staff can adjust the position of the diversion block 21 along the first direction to change the flow ratio entering the first test area 11 and the third test area 13, thereby forming a balanced or biased diversion state, so as to more realistically simulate the scenario where the main waterway splits into two sides after passing through islands, reefs, capes or branch channels.

[0088] In one embodiment, the diversion block 21 is an isosceles triangular diversion block. The apex of the isosceles triangular diversion block can face the water flow entering the diversion area in the second test area 12, and its two sides form a first guide surface facing the first test area 11 and a second guide surface facing the third test area 13, respectively.

[0089] When the water flow in the second test zone 12 reaches the apex of the isosceles triangular diversion block, the water flow can flow along the two guide surfaces to the first test zone 11 and the third test zone 13 respectively. Since the structures of the two guide surfaces are basically symmetrical, when the pump set operating conditions are similar, it is beneficial to distribute the water flow in the second test zone 12 to the two test zones on both sides more evenly; when it is necessary to form a non-uniform flow, the water flow intensity on both sides can also be changed by combining the pump set power difference or the position of the diversion block 21.

[0090] In one embodiment, the diversion component 20 further includes a first diversion channel 22 and a second diversion channel 23; the first diversion channel 22 is disposed between the diversion block 21 and the first test area 11; and the second diversion channel 23 is disposed between the diversion block 21 and the third test area 13.

[0091] The first guide channel 22 is used to further guide the water flow moving along the first guide surface to the first test area 11; the second guide channel 23 is used to further guide the water flow moving along the second guide surface to the third test area 13.

[0092] In this embodiment, guide plates or other guiding structures can be provided in the first guide channel 22 and the second guide channel 23. The first guide channel 22 and the second guide channel 23 can limit the diffusion range of the water flow after diversion, reduce the possibility of disordered dispersion or local swirling of the water flow at the diversion end, and make the water flow enter the corresponding test area more stably.

[0093] As one implementation, guide blocks 24 may be provided in the first guide channel 22 and the second guide channel 23. Specifically, the guide blocks 24 may be provided in the corner area of ​​the pool body 10 to guide the water flow entering the corner.

[0094] As one implementation, a flow stabilizer 25 can be installed inside the pool body 10 in front of the pump unit along the water flow direction.

[0095] In one embodiment, a truss assembly 50 is also included; the truss assembly 50 is detachably disposed on the pool body 10; and a pump assembly 30 is detachably disposed on the truss assembly 50.

[0096] In one embodiment, the pump assembly 30 includes a plurality of pump bodies; the truss assembly 50 is provided with a plurality of pump mounting positions 51; the plurality of pump mounting positions 51 are arranged in a matrix; and the plurality of pump bodies are detachably disposed on the plurality of pump mounting positions 51.

[0097] In one implementation, multiple pump bodies can be installed into the truss assembly 50 in the same direction, for example, from top to bottom. After the pump body is installed in the pump mounting position 51, it can be secured with bolts or the like. Similarly, when maintenance or replacement is required, the pump body can be removed from bottom to top.

[0098] With the truss assembly 50, this solution eliminates the need to remove the entire truss assembly 50 or damage the pool structure when maintaining the pump units, adding or removing pump units, or changing the installation location of the pump units, thereby reducing the workload of the staff.

[0099] In one embodiment, at least one of the first test area 11, the second test area 12, and the third test area 13 has installation stations on both sides; the truss assembly 50 is detachably installed at the installation station. The installation station can be a connection structure provided on the pool wall or pool edge support structure, and the installation structure can be configured as a pre-embedded connector embedded in the pool body.

[0100] In one embodiment, installation stations can be provided on both sides of the first test area 11, the second test area 12, and the third test area 13. The installation stations provide multiple optional arrangement positions for the pump assembly 30, enabling the test system to adjust the pump assembly installation position according to test requirements, while improving equipment reusability and ease of modification.

[0101] In one embodiment, a detection component is also included; the detection component includes at least one of a flow rate sensor, a flow sensor, a pressure sensor, and a water level sensor; the detection component is disposed within the pool body 10 and is electrically connected to the control component 40.

[0102] Specifically, the flow velocity sensor and pressure sensor can be set at the target measurement position in the first test area 11, the second test area 12 or the third test area 13 to obtain the water flow velocity and water pressure data at the corresponding positions; the flow sensor can be set in the output area of ​​the pump group to detect the output flow of the pump group; and the water level sensor can be used to detect the liquid level status in the pool 10.

[0103] Before the test begins, the control component 40 can determine whether the water level and initial flow field state in the pool 10 meet the test requirements based on the initial detection results of the detection component. During the test, the control component 40 can receive flow velocity, flow rate, pressure, or water level information collected by the detection component to evaluate whether the actual flow field reaches the preset operating conditions.

[0104] The dual-sided flow-generating deep-water test pool system provided in this application sets up a first test zone 11, a second test zone 12, and a third test zone 13 within a single large pool 10, all of which are in the same circulating water body. It is equipped with a flow-dividing component 20, pump components 30 corresponding to the three test zones respectively, and a control component 40. This allows the same test platform to form various test environments such as single-pump flow field, dual-pump flow field, triple-pump flow field, and confluence flow field. This improves the simulation capability of complex water flow environments within a limited test space, reduces the need to set up multiple independent flow-generating facilities for different test scenarios, reduces equipment construction and maintenance costs, and improves the utilization rate of the test platform.

Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments 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.
