Description

Technical Field

[0001] This invention belongs to the technical field of marine engineering water tank test devices, and particularly relates to a wind measurement system and method for marine engineering test water tanks. Background Technology

[0002] The ocean is rich in energy, mineral, and biological resources, and is also an important international trade route. Strengthening marine science and technology research and development and industrial upgrading, enhancing the ability to develop marine resources, and building a modern marine industry system are of great significance for promoting high-quality economic development, safeguarding national maritime rights and interests, and ensuring national security. The development of marine resources cannot be separated from the support of various marine engineering equipment.

[0003] Marine engineering test pools are crucial infrastructure for the research and development of marine engineering equipment. To simulate marine environmental conditions, these pools typically require wind, wave, and current generation devices. However, existing marine engineering test pools generally lack a corresponding wind field measurement system for their wind generation systems. Understanding the generated wind field is often limited to local wind speed measurements, making it difficult to fully grasp the overall wind field and its changes during the test.

[0004] Furthermore, since the wind field cannot be fully measured, the wind generation system can only simulate simple wind fields. The wind array composed of multiple wind turbines cannot achieve precise control of individual wind turbines, making it difficult for the wind array to fully exert its effectiveness. Therefore, it cannot meet the requirements of water tank model tests for complex wind fields.

[0005] Other existing wind field measurement methods, such as PIV (Particle Image Velocity), which uses laser illumination and high-speed photography to track the trajectory of suspended tracer particles and obtain the fluid velocity field distribution, are relatively complex to operate and costly. Lidar velocimetry, based on the Doppler frequency shift effect, measures the wind field by inverting the frequency change of the echo signal through the interaction between the emitted laser beam and aerosol particles in the atmosphere. This method is suitable for measuring wind fields within a range of 40 to 300 meters from the radar, but is not suitable for laboratory spaces and is relatively expensive.

[0006] Therefore, there is an urgent need for a wind measurement system and method for marine engineering test pools to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a wind measurement system and method for a marine engineering test pool, so as to solve the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following solution: The present invention provides a wind measurement system for a marine engineering test pool, comprising: A gantry frame spans both sides of the test water tank, and a lifting unit is installed on the gantry frame; A traveling mechanism is installed on both sides of the bottom end of the gantry.

[0013] According to the present invention, a wind measurement system for a marine engineering test pool is provided, wherein the wind speed measurement unit includes multiple wind speed sensors, and a vertical telescopic rod is installed at the bottom end of the support beam via a vertical telescopic drive servo motor, and the multiple wind speed sensors are installed at equal intervals along the axial direction at the telescopic end of the vertical telescopic rod.

[0014] According to the present invention, a wind measurement system for a marine engineering test pool is provided, wherein the data acquisition and calculation system includes a data acquisition unit and a computer system, the wind speed measurement unit is electrically connected to the data acquisition unit, and the walking mechanism, the beam lifting mechanism, the lateral sliding mechanism and the data acquisition unit are respectively electrically connected to the computer system.

[0015] According to the present invention, a wind measurement system for a marine engineering test pool is provided, wherein the wind speed sensor is a miniature ultrasonic wind speed sensor.

[0016] According to the wind measurement system of the marine engineering test pool provided by the present invention, the first crossbeam is a hollow I-beam.

[0017] A method for measuring wind field in a marine engineering test pool includes the following steps: The three-dimensional spatial range and scanning measurement step size of the wind field area to be measured are set through the data acquisition and calculation system.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Reference Figures 1-3 This invention provides a wind measurement system for a marine engineering test pool, comprising: A gantry frame spans both sides of the test water tank, and a lifting unit is installed on the gantry frame. The traveling mechanism is installed on both sides of the bottom end of the gantry. The traveling mechanism is used to drive the gantry to move longitudinally and horizontally along the track laid on the side of the pool. A beam lifting mechanism is vertically connected to the gantry, and a lateral sliding mechanism is slidably connected to the beam lifting mechanism. The wind speed measurement unit is mounted on the lateral sliding mechanism and is used to measure wind speed. The data acquisition and calculation system, the walking mechanism, the beam lifting mechanism, the lateral sliding mechanism, and the wind speed measurement unit are all electrically connected to the data acquisition and calculation system.

[0024] As an optional implementation, the gantry includes two side columns 1, which are arranged in parallel, and a first crossbeam 2 is fixedly connected to the top of the two side columns 1.

[0025] In one embodiment of the present invention, the gantry includes two side columns 1 and a first crossbeam 2, forming a U-shape. The gantry structure is made of ordinary steel and serves as the supporting and motion foundation frame for the entire system, spanning across both sides of the test water tank. A lifting unit is installed on the gantry to support and drive the subsequent measuring components for vertical movement. The gantry structure provides stable and reliable support across the space, ensuring that the entire measurement system can cover the effective test area of ​​the water tank. Its spanning design avoids encroachment on the internal space of the water tank and does not affect the normal wave generation and flow generation functions of the water tank. The lifting unit provides the structural foundation for subsequent precise vertical measurements.

[0026] As an optional implementation, the walking mechanism includes a left walking beam 3 and a right walking beam 4, which are fixedly connected to the bottom ends of the two side columns 1 respectively. Both the left walking beam 3 and the right walking beam 4 are equipped with a walking drive servo motor 5 and rollers, and the walking drive servo motor 5 is used to drive the rollers to rotate.

[0027] In one embodiment of the present invention, the traveling mechanism includes a left traveling beam 3 and a right traveling beam 4. The left traveling beam 3 and the right traveling beam 4 are respectively fixedly connected to the lower ends of the columns 1 on both sides of the gantry through their top flanges. The left traveling beam 3 and the right traveling beam 4 are made of ordinary steel. The traveling mechanism is installed on both sides of the bottom end of the gantry. Its main function is to drive the entire gantry to move longitudinally and horizontally along the track pre-laid on the side of the pool, realizing the system's large-range longitudinal movement capability. The traveling mechanism is equipped with a traveling drive servo motor 5 and rollers. The traveling drive servo motor 5 controls the rollers to rotate and move on the track. The track guide ensures the linearity and stability of the movement, which is the key to realizing long-distance, continuous spatial scanning. It transforms the entire measurement system into a mobile scanning platform.

[0028] As an optional implementation, the beam lifting mechanism includes a second beam 6, a lifting slide rail 7 fixedly connected to the side column 1, the second beam 6 being slidably connected to the lifting slide rail 7, and the second beam 6 sliding on the lifting slide rail 7 via a lifting drive motor 8.

[0029] In one embodiment of the present invention, the second crossbeam 6 is slidably connected to the lifting slide rail 7. A lifting drive motor 8 and gears are mounted on the second crossbeam 6. By sliding the second crossbeam 6 on the lifting slide rail 7 via the lifting drive motor 8 and gears, the crossbeam lifting mechanism provides the system with precise adjustment capability in the Z-axis direction (vertical height). By controlling its lifting, the height of the measuring sensor array above the water can be changed, thereby enabling the measurement of wind field information at different vertical profiles. This is crucial for studying wind profile changes and boundary layer effects.

[0030] As an optional implementation, the lateral sliding mechanism includes a lateral moving slide rail 9, which is fixedly connected to the second crossbeam 6. A support beam 10 is slidably connected to the lateral moving slide rail 9, and the support beam 10 slides on the lateral moving slide rail 9 via a lateral moving drive servo motor 11.

[0031] In one embodiment of the present invention, the support beam 10 is slidably connected to the transverse sliding rail 9. A transverse drive servo motor 11 and gears are mounted on the support beam 10. The support beam 10 slides on the transverse sliding rail 9 via the transverse drive servo motor 11 and gears. This transverse sliding mechanism enables the system to achieve precise scanning capability in the Y-axis direction (lateral). Combined with the walking mechanism (X-axis) and the beam lifting mechanism (Z-axis), it forms a complete three-dimensional Cartesian coordinate motion system, enabling the measurement unit installed at the end to reach any preset three-dimensional coordinate point covering the entire target water body.

[0032] As an optional implementation, the wind speed measurement unit includes multiple wind speed sensors 12. A vertical telescopic rod 14 is mounted on the bottom end of the support beam 10 via a vertical telescopic drive servo motor 13. The multiple wind speed sensors 12 are installed at equal intervals along the axial direction at the telescopic ends of the vertical telescopic rod 14.

[0033] In one embodiment of the present invention, the vertical telescopic drive servo motor 13 drives the vertical telescopic rod 14 to extend and retract, thereby moving the wind speed sensor 12. The wind speed measurement unit is a sensing component that directly acquires physical quantities such as wind speed and wind direction. As the sensing terminal of the system, the wind speed measurement unit is responsible for collecting raw wind field data at each specified spatial point. It is installed at the end of the motion system, ensuring the controllability and accuracy of the measurement position. Multiple wind speed sensors 12 are installed on a support beam 10, which can simultaneously measure wind data at multiple height points on a vertical line after one lateral and longitudinal positioning, greatly improving the scanning measurement efficiency, especially suitable for situations requiring dense vertical profiles. The height of each wind speed sensor 12 is controlled by an independent vertical telescopic rod 14 and drive motor 13. This means that the position and density of vertical measurement points can be flexibly configured as needed, without being limited by a fixed spacing. For example, denser measurement points can be set in the near-water boundary layer region, and sparser measurement points can be set at high altitudes. The telescopic rod can extend the sensor a certain distance away from the support structure, effectively reducing the disturbance of the local flow field near the sensor by the support beam 10 and other structures, and improving the accuracy of the measurement.

[0034] As an optional implementation, the data acquisition and computing system includes a data acquisition unit 15 and a computer system 16. The wind speed measurement unit is electrically connected to the data acquisition unit 15, and the walking mechanism, the beam lifting mechanism, the lateral sliding mechanism, and the data acquisition unit 15 are electrically connected to the computer system 16.

[0035] In one embodiment of the present invention, the data acquisition and computing system is a core unit integrating control and data processing. The walking mechanism, the beam lifting mechanism, the lateral sliding mechanism, the vertical telescopic rod 14, and the wind speed measurement unit are all electrically connected to the data acquisition and computing system via cables, receiving its commands and transmitting data back. This system is responsible for precisely coordinating the movement mechanisms in three directions, enabling the wind speed measurement unit to automatically move to each measurement point according to a predetermined path and speed. After the measurement point is in place, it triggers and synchronously acquires signals from the wind speed sensor. The massive amount of spatially discrete wind speed data acquired is processed through storage, calibration, filtering, interpolation, and fitting, ultimately reconstructing a continuous three-dimensional wind field model and achieving visualization and characteristic parameter analysis. This system achieves complete automation and intelligence in the measurement process, greatly improving measurement efficiency and data availability.

[0036] As an alternative implementation, the wind speed sensor 12 is a miniature ultrasonic wind speed sensor.

[0037] In one embodiment of the present invention, the ultrasonic anemometer 12 has advantages such as having no moving parts, fast response speed, high measurement accuracy, simultaneous measurement of three-dimensional wind speed and direction, and low start-up wind speed. The use of a miniature sensor, with its small size and light weight, further reduces the sensor's own obstruction and interference to the airflow field, making it particularly suitable for high spatial resolution fine measurements. Simultaneously, its rapid response characteristics can capture instantaneous pulsation information of the wind field, providing possibilities for turbulence analysis.

[0038] As an optional implementation, the first crossbeam 2 is a hollowed-out I-beam.

[0039] In one embodiment of the present invention, the I-beam structure, while ensuring sufficient bending strength, exhibits high material utilization efficiency. The use of a hollow design (such as perforations or a lattice structure) significantly reduces the self-weight of the beam, thereby lowering the load requirements on the gantry columns and traveling mechanism. More importantly, the hollow structure effectively reduces the wind resistance experienced by the beam, reducing both the additional load and vibration caused by wind resistance during system movement and the beam's obstruction and wake interference on the wind field below, thus improving the overall cleanliness of the measurement environment.

[0040] A method for measuring wind field in a marine engineering test pool includes the following steps: The three-dimensional spatial range and scanning measurement step size of the wind field area to be measured are set through the data acquisition and calculation system; The data acquisition and calculation system controls the walking mechanism, the beam lifting mechanism and the lateral sliding mechanism to work together to drive the wind speed measurement unit to move sequentially to each preset three-dimensional space measurement point for measurement; At each measurement point, the data acquisition and calculation system synchronously collects data measured by the wind speed measurement unit; The data acquisition and computing system processes the wind speed data of all spatially discrete points, reconstructs a continuous three-dimensional wind field distribution model, and performs visualization and characteristic parameter analysis.

[0041] In one embodiment of the present invention, during use, the three-dimensional spatial range (X_min-X_max, Y_min-Y_max, Z_min-Z_max) and scanning measurement step size (ΔX, ΔY, ΔZ) of the wind field area to be measured are set through a data acquisition and calculation system (specifically, the software interface of computer system 16). This enables customized and programmed measurement. Users can flexibly define the scanning space and density according to the specific experimental model size, the wind field area of ​​interest, and the required measurement resolution. The software automatically generates a three-dimensional coordinate sequence of all points to be measured.

[0042] Automatic scanning measurement: The data acquisition and computing system controls the walking mechanism, beam lifting mechanism, and lateral sliding mechanism to work in concert, driving the wind speed measurement unit to move sequentially to each preset three-dimensional spatial measurement point according to a predetermined path plan (usually scanning row by row or layer by layer). Under the precise control of the computer, the three-axis motion system efficiently and orderly transports the sensor array to each target point. The coordinated action ensures smooth and rapid movement, avoiding unnecessary shaking and waiting time.

[0043] Synchronous Data Acquisition: At each measurement point, after the moving mechanism has come to a stop and reached a preset settling time, the data acquisition and calculation system synchronously acquires data measured by the wind speed measurement unit (all wind speed sensors 12). Typically, data is collected for a period of time (e.g., several seconds to tens of seconds) at each point to calculate the average value and statistics, and this data is bound and stored with the three-dimensional coordinates of the current point. This achieves a strict correlation between data and spatial location. Synchronous acquisition ensures the temporal consistency of data from various height sensors at the same spatial point, which is crucial for analyzing the vertical wind field structure. The automated acquisition process eliminates human error.

[0044] Data processing and wind field reconstruction: The data acquisition and computing system processes the wind speed data from all spatially discrete points to reconstruct a continuous three-dimensional wind field distribution model, which is then visualized and its characteristic parameters analyzed. This is a key step in transforming data into knowledge. Processing methods may include: Data preprocessing: outlier removal, filtering and noise reduction, coordinate transformation, etc.

[0045] Spatial interpolation / fitting: Using methods such as Kriging interpolation, radial basis function (RBF) interpolation, and polynomial fitting, discrete point data are transformed into a continuous spatial scalar field (wind speed magnitude) or vector field (wind speed and direction).

[0046] Visualization: Generate wind speed cloud maps, isosurface maps, 3D streamline maps, or vector slice maps to intuitively display the wind field distribution.

[0047] Feature analysis includes extracting horizontal / vertical wind profile curves, calculating regional average wind speed and turbulence intensity, analyzing wind field uniformity, plotting turbulence energy spectra, and calculating spatial correlations. The final output is a comprehensive, quantitative, and visualized wind field measurement report, providing strong data support for experimental analysis.

[0048] In one embodiment of the present invention, before the test begins, it is ensured that all mechanisms of the wind measurement system are operating normally and the sensors are calibrated. The dedicated software on the computer system 16 is then started. The user sets the measurement area in the software according to the requirements of this test. The scanning step size is set as follows: ΔX = 1.0 meter, ΔY = 1.0 meter, ΔZ = 0.5 meters (when the support beam 10 is fixed at the Y position, vertical scanning is achieved by simultaneously measuring at different heights using 8 sensors. If a denser vertical scan is required, the sensor height can be adjusted multiple times).

[0049] The software automatically calculates and generates a list of three-dimensional coordinates for all measurement points. At the same time, it is set to collect wind speed data for 10 seconds (sampling frequency 50Hz) after each measurement point stabilizes, and calculate the average wind speed, wind direction and turbulence intensity within 10 seconds.

[0050] The motion control module of computer system 16 sends commands to each servo drive sequentially according to the optimized path. First, the walking drive servo motor 5 actuates, moving the gantry to the first X-coordinate position. Next, the lateral drive servo motor 11 actuates, moving the support beam 10 to the first Y-coordinate below that X position. Then, the lifting drive motor 8 actuates, adjusting the second crossbeam 6 to a predetermined starting height layer (e.g., Z=0.5m). Simultaneously, the vertical extension drive servo motor 13, according to a preset, adjusts the eight ultrasonic wind speed sensors 12 to eight different heights to be measured below that Y position (e.g., 0.5m, 0.75m, 1.0m, 1.25m, 1.5m, 2.0m, 2.5m, 3.0m). The system waits for 1 second to ensure mechanical vibration attenuation. Then, the computer triggers the data acquisition unit 15 to begin collecting data from the eight sensors for 10 seconds. After collection, the data, along with the spatial coordinates of the current point (X, Y, Z_i, i=1-8), is saved to the database. Next, the lifting drive motor 8 raises the second crossbeam 6 to the next height level (e.g., Z=3.5m), and the vertical telescopic drive servo motor 13 adjusts the sensor to the corresponding 8 heights of that level, repeating the data acquisition. This continues until all preset height levels at that (X, Y) coordinate have been measured. Then, the horizontal traverse drive servo motor 11 drives the support beam 10 to move to the next Y coordinate, repeating the steps. After all Y coordinates at that X position have been measured, the traveling mechanism drives the gantry to move to the next X coordinate, repeating the entire process. The entire scanning process is fully automatic, and the software interface displays the current measurement progress, position, and a preview of the acquired data in real time.

[0051] After all measurements are completed, the software indicates the measurement is finished. The user then starts the post-processing analysis module. The software automatically loads all data. A simple data quality check is performed, such as removing obvious outliers caused by momentary sensor obstruction. The raw voltage signal is converted into wind speed and direction values ​​according to the calibration coefficient. A built-in interpolation algorithm (e.g., ordinary Kriging interpolation) is invoked to interpolate the discrete (X, Y, Z, U, V, W) data points (U, V, W being the three-dimensional wind speed components) onto a regular and denser three-dimensional grid. Based on the interpolated data, various graphs are generated. After analysis, the software can automatically generate a PDF measurement report containing key charts, data, and basic conclusions.

[0052] Example 2: Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the support beam 10 is arranged vertically, and the bottom end of the vertical telescopic rod 14 is provided with a hinge point. The support beam 10 is adjusted from horizontal to vertical by adjusting the hinge point. When the support beam 10 is arranged vertically, multiple wind speed sensors 12 are installed at equal intervals along the horizontal direction at the telescopic end of the vertical telescopic rod 14. This is suitable for measuring the wind speed distribution at different horizontal positions at the same height, which facilitates fine scanning of the horizontal profile.

[0053] In one embodiment of the present invention, the support beam 10 can be flexibly switched between horizontal and vertical arrangement through the hinge point design to adapt to different measurement needs. When it is necessary to focus on studying the horizontal uniformity or lateral gradient of the wind field, the vertically arranged support beam 10, together with multiple wind speed sensors 12, can simultaneously collect data at different horizontal positions at the same height, which can efficiently obtain the characteristics of wind speed changes in the horizontal direction.

[0054] This embodiment further expands the measurement dimensions and adaptability of the wind measurement system by adjusting the arrangement of the support beam 10. The vertical arrangement is particularly suitable for rapid scanning of horizontal wind field profiles, improving the system's ability to analyze complex wind field structures; at the same time, the hinged structure design enhances the system's flexibility and reconfigurability, meeting the measurement needs of various test scenarios.
