Description

Technical Field

[0001] This invention relates to the field of wind-powered propulsion for ships, specifically a measurement and control device for wind-powered propulsion model testing of ship models. Background Technology

[0002] In response to the global trend towards green and low-carbon development, the shipbuilding industry is constantly seeking greener and more economical energy-saving devices to reduce its dependence on fossil fuels. Wind-powered propulsion devices utilize offshore wind energy to provide auxiliary propulsion for ship navigation, which has far-reaching significance for reducing ship carbon emissions and improving energy efficiency, and has become a research hotspot in the shipping industry in recent years. While research on wind-powered propulsion devices has yielded some results both domestically and internationally, most devices are still in the prototype stage. Researchers urgently need more testing methods and equipment to study and validate wind-powered propulsion technology. Currently, research on ship model wind-powered propulsion mainly relies on ship model wind simulation methods. However, establishing a simulation model requires setting a large number of complex and numerous simulation model input parameters, and the values ​​of these parameters are often derived from empirical or theoretical data, resulting in a certain degree of uncertainty. This uncertainty can lead to significant deviations between the final simulation results and actual measurements. Therefore, simulation methods are insufficient to accurately predict the wind-powered propulsion effect on real ships. Ship model testing offers higher reliability and can more effectively solve the above problems.

[0003] Currently, most existing ship model wind-powered propulsion test devices follow the testing equipment used in fields such as wind power generation, focusing more on the efficiency of blades in wind power conversion, structural strength and stiffness equivalence, and electric transmission. They exhibit significant functional limitations and have obvious shortcomings in terms of wind-powered propulsion effects and ship model coupling effects. The windward angle adjustment of traditional wind-powered propulsion test devices is often done manually, which cannot accurately adjust the windward angle, has poor repeatability, and cannot monitor the angle changes in real time. Furthermore, existing testing devices and methods often only test a single wind-powered propulsion device. However, in actual use, ships often carry multiple wind-powered propulsion devices. Current testing devices cannot achieve comprehensive acquisition, accurate measurement, analysis, and comparison of wind power data from multiple ship models, making it difficult to cope with complex application testing scenarios. This lack of flexibility and practicality limits the research and development of ship wind-powered propulsion technology. Summary of the Invention

Detailed Implementation

[0023] This invention provides a measurement and control device for wind-powered propulsion model testing of ship models, including a testing device, such as... Figure 1-4 As shown, the testing device includes: a fan unit 1, a support component 2, a rotating platform 3, a force sensor 4, and a base 5. The measurement and control device also includes a control cabinet 6 and a data acquisition unit 7. The fan unit 1 includes a fan drive motor 11, fan blades (not shown in the figure) driven by the fan drive motor 11, and a driver connected to the fan drive motor 11. The fan drive motor 11 is designed with a universal drive interface, allowing simulation tests of wind power devices of different power and forms to be performed by replacing fans of different sizes and shapes. In this embodiment, the fan blades are locked and fixed to the fan drive motor 11 by a locking cap (not shown in the figure), and the fan drive motor 11 drives the fan blades to rotate, simulating an equivalent wind-driven booster device. The driver can be connected to the control cabinet 6, modulating and outputting the digital information from the control cabinet 6 to the electrical signals required for different speeds of the fan drive motor 11. Furthermore, the driver integrates communication interfaces such as a serial port, allowing real-time data interaction and operation control with a host computer 8 after connecting a communication cable.

[0024] Support member 2 supports the wind turbine unit 1, ensuring a certain height distance between the wind turbine unit 1 and the deck of the model ship. A rotating platform 3 drives the support member 2 to rotate. The rotating platform 3 includes a mounting base 32, a rotating connecting platform 31 rotatable relative to the mounting base 32, and a rotating drive mechanism that drives the rotating connecting platform 31 to rotate relative to the mounting base 32. The support member 2 is fixed to the rotating connecting platform 31 and can rotate around its axis. The rotating drive mechanism of the rotating platform 3 can communicate with the host computer 8 via RS485 serial communication for real-time data exchange and monitoring. By driving the wind turbine unit 1 to rotate horizontally to the required angle at a set speed, the rotating platform 3 simulates the rotation of a real ship's sail, thus automatically adjusting the windward angle in real time. The windward angle is a crucial indicator of the wind-powered propulsion device, significantly affecting its propulsion efficiency. Data on the automatic change of the windward angle can be measured by a force sensor 4.

[0025] In this embodiment, the force sensor 4 is a three-part force sensor. The upper end of the force sensor 4 is fixed to the mounting base 32 of the rotating platform 3, which is tightly fixed with bolts. The lower end of the force sensor 4 is also fixed to the base 5 with bolts. The lower end of the base 5 is fixed to the ship. When the fan blades of the wind turbine rotate at high speed and generate wind force, the thrust generated by the wind turbine will directly act on the three-part force sensor. The elastic body inside the sensor will deform and convert the deformation of the elastic body into a certain electrical signal output. After signal modulation and analog-to-digital conversion by the data acquisition unit 7, it is finally converted into the specific magnitude of the force. Therefore, the measurement and control device designed in this scheme can accurately measure the magnitude of the thrust generated by the wind turbine on the entire device in all directions. When the rotating platform unit drives the upper components to rotate, the direction of the measured bow can always be kept consistent with the positive direction of the force received by the entire device.

[0026] The rotary drive mechanism includes a rotary drive motor 33, a worm gear (not shown in the figure) driven by the rotary drive motor 33, and a worm wheel (not shown in the figure) meshing with the worm gear. The worm wheel is fixed to the rotary connection platform 31. The structure and transmission method of the worm wheel and worm gear are existing. The rotary drive motor 33 is equipped with an encoder, which can monitor and provide feedback on the current boost wind direction of the model in real time. Through the above structure, the rotary platform 3 can achieve automated control at any time and any angle, which is helpful for research on windward angle optimization and boost efficiency improvement tests. In this embodiment, the upper end of the mounting base 32 of the rotary platform 3 is provided with multiple mounting threaded holes, and the support member 2 is fixedly installed with the rotary platform 3 through bolts and threaded holes.

[0027] like Figure 2 and Figure 4 As shown, the support member 2 includes a hollow base rod 21 and a first lifting rod 22 that can move up and down along the hollow part of the base rod 21. The base rod 21 is fixed to the rotating platform 3, and the first lifting rod 22 is rotatably connected to the base rod 21. The lifting and lowering of the first lifting rod 22 relative to the base rod 21 can realize the lifting and lowering of the wind turbine unit 1 in one operation, thereby achieving accurate control of the height of the wind turbine unit 1, and thus achieving effective control of the height position of the wind center point. This well meets the design requirements of wind power tests for different ship models, as well as the test requirements of raising and lowering the sails in different states during model tests.

[0028] The outer wall of the first lifting rod 22 is provided with a first limiting groove 221 extending vertically. The bottom rod 21 is fixed with a first limiting key 211, which cooperates with the first limiting groove 221. The first limiting key 211 and the first limiting groove 221 can form a track for the extension and retraction of the first lifting rod 22, making the lifting and lowering of the first lifting rod 22 more stable. On the other hand, when the bottom rod 21 rotates, it will generate a torque on the first lifting rod 22 in the circumferential direction, causing it to rotate synchronously with the bottom rod 21.

[0029] In this embodiment, the first lifting rod 22 is a hollow rod, and the support member 2 further includes a second lifting rod 23 that can move up and down along the hollow part of the first lifting rod 22. The second lifting rod 23 is rotatably connected to the first lifting rod 22, and the fan unit 1 is fixedly connected to the second lifting rod 23. The outer wall of the second lifting rod 23 is provided with a second limiting groove 231 that extends up and down, and the first lifting rod 22 is fixed with a second limiting key 222, which cooperates with the second limiting groove 231. The lifting and lowering of the second lifting rod 23 relative to the first lifting rod 22 can further increase the lifting range of the fan unit 1, thereby achieving effective control of the height position of the wind center point within a larger height range.

[0030] like Figure 4 As shown, the side wall of the base rod 21 has a limiting hole 212 near its upper end, perpendicular to the length direction of the base rod 21. The support member 2 also includes a limiting bolt 24, one end of which passes through the limiting hole 212 and abuts against the first lifting rod 22. The limiting bolt 24 can further enhance the synchronization of the first lifting rod 22 and the base rod 21 in rotation. In this embodiment, the limiting bolt 24 and the first limiting key 211 are located on the same plane passing through the axis of the base rod 21. In this way, the force on the first lifting rod 22 can be more balanced.

[0031] like Figure 5 and Figure 6 As shown, in this embodiment, the measurement and control device includes multiple testing devices, each constituting a module, which can be added or removed as needed. The measurement and control device also includes a host computer 8, such as... Figure 6 As shown, the force sensor 4 of each of the test devices is connected to the data acquisition unit 7, and the data acquisition unit 7 transmits the data collected from the force sensors 4 of all the test devices to the host computer 8. Real-time control and monitoring of multiple wind-powered booster model test devices can be achieved through the control cabinet 6, the data acquisition unit 7, and the host computer 8.

[0032] In addition, such as Figure 6As shown, the driver of each fan unit 1 of the test device is connected to the control cabinet 6, and the rotation drive mechanism of the rotating platform 3 is also connected to the control cabinet 6. The control cabinet 6 can control the fan units 1 of all test devices separately, and control the rotating platform 3 of all test devices separately. The operator can input and set the operating parameters on the host computer 8 according to the test requirements. During the ship model test, the operator will control the motion operation of the measurement and control device in real time through the host computer 8 according to the project test requirements to ensure that the wind force and wind direction output by the fan simulation meet the design specifications.

[0033] The measurement and control device for wind-powered propulsion model testing of ship models of the present invention is multifunctional, compact, and easy to assemble and disassemble, and can be modularly combined and used according to project design requirements. These testing devices can be mounted in multiple parallel configurations at the designed locations on the ship model, depending on the test layout requirements, such as... Figure 5 As shown, combined joint debugging is achieved. During the test process, the operator can directly control multiple test devices through the host computer 8, and precisely adjust the dynamic parameters such as the fan speed and direction on each device, thereby simulating multiple sets of booster wind force model combinations and joint test scenarios.

[0034] Furthermore, through the host computer interface, staff can intuitively monitor the thrust curve changes generated by the wind force of each model, providing strong support for in-depth research on the interaction mechanism between wind models. This method of joint debugging using multiple sets of measurement and control devices can, on the one hand, verify the accuracy of existing model designs and simulation calculations, and on the other hand, allow for continuous experimentation with different model combination schemes, joint testing, and the collection and analysis of wind data. This process greatly facilitates comparative analysis of overall schemes regarding wind magnitude, wind direction, wind center location, and placement, helping to identify and optimize the best combination strategy. This allows for further research into the mutual coupling effects between the designed wind models, providing fundamental experimental support for systematic research on fan blade structure design and other aspects in ship wind-powered propulsion experiments.
