Description

Technical Field

[0001] This utility model relates to the field of aerodynamic equipment technology, and in particular to a multi-stage vector array power device for use in wind tunnels. Background Technology

[0002] A wind tunnel is an experimental device used for aerodynamic research. Its core function is to artificially generate and control airflow to simulate the flow characteristics of gases around aircraft or objects. By precisely measuring the forces exerted by the airflow on objects and observing related physical phenomena, wind tunnel experiments provide crucial scientific data support for various engineering fields. Wind tunnel technology has wide applications in aerospace, automotive industry, architectural design, wind energy utilization, and sports science, among others.

[0003] Although wind tunnels play an important role in aerodynamic research, they have many limitations in practical applications, mainly in the following aspects:

[0004] First, due to limitations in flow field conditions, boundary effects cause the flow field within the wind tunnel to be constrained by boundaries, resulting in differences from the actual flight environment. Furthermore, the scaling effect also limits the similarity between the model and the real aircraft, affecting the accuracy of experimental results.

[0005] Secondly, traditional wind tunnels can usually only provide a constant wind field with a certain flow rate and direction, which is difficult to simulate complex and ever-changing real-world environments. Their design is relatively fixed and it is difficult to flexibly adapt to different operating scenarios. Utility Model Content

[0028] In the technical solution provided by this utility model embodiment, the frame component is used to support the wind field component. The frame component includes a first frame 11, a second frame 12, a first rotating shaft 13, and a second rotating shaft 14. One end of the first rotating shaft 13 is connected to the inner side of the first frame 11, and the other end is connected to the second frame 12. The second rotating shaft 14 is located inside the second frame 12. The wind field component is used to generate a wind field. The wind field component includes a third frame 21 and multiple fan components 22. The third frame 21 includes a frame body and multiple support rods 211. Multiple mounting holes 213 are provided inside the frame body, and the support rods 211 are located in the mounting holes 213. Each fan component 22 is connected to each support rod 211 in a one-to-one correspondence. Compared with the prior art, wind tunnels are used to generate and control airflow to simulate the flow characteristics of gas around aircraft or objects. Wind tunnels play an important role in aerodynamic research. However, there are many limitations in actual use, mainly reflected in the following aspects: First, the limitation of flow field conditions. Boundary effects will cause the flow field in the wind tunnel to be constrained by the boundary, thus differing from the real flight environment. Furthermore, the scaling effect also limits the similarity between the model and the real aircraft, affecting the accuracy of the experimental results. Second, traditional wind tunnels can usually only provide a constant wind field with a certain flow velocity and direction, which is difficult to simulate complex and ever-changing real environments. Their design is relatively fixed and it is difficult to flexibly adapt to different operating scenarios. In this technical solution, multiple wind turbine components 22 are set in the third frame 21. The wind turbine components 22 generate a wind field by rotating. The lateral and longitudinal angles of the wind field components are adjusted by the first frame 11, the second frame 12, the first rotating shaft 13 and the second rotating shaft 14. At the same time, the wind speed and wind direction are changed by adjusting the rotation angle and rotation speed of different wind turbine components 22, so that the wind field produces complex multi-dimensional wind speed changes. Moreover, wind speed and wind tunnel tests can be carried out outdoors, eliminating the influence of the existing wind tunnel boundary effect and scaling effect on the wind field test, thereby achieving the technical effect of improving the applicability of the wind field.

[0029] The aforementioned frame components support the wind farm components. The frame components include a first frame 11, a second frame 12, a first rotating shaft 13, and a second rotating shaft 14. One end of the first rotating shaft 13 is connected to the inner side of the first frame 11, and the other end is connected to the second frame 12. The second rotating shaft 14 is located inside the second frame 12. The first frame 11 and the second frame 12 are rectangular or circular frames. The first rotating shaft 13 is located at both ends of the inner side of the first frame 11, and the axes of the two first rotating shafts 13 coincide. The outer ends of both ends of the second frame 12 are rotatably connected to the first rotating shafts 13, allowing the second frame 12 to rotate within the first frame 11 around the axis of the first rotating shaft 13. The second rotating shaft 14... The second frame 12 is located inside the second rotating shaft 14. There are two second rotating shafts 14, with their axes coinciding. The axes of the first rotating shaft 13 and the second rotating shaft 14 are perpendicular to each other. Specifically, a driver is installed on the first rotating shaft 13 and the second rotating shaft 14. The driver uses an existing micro-driver, capable of driving the first rotating shaft 13 and the second rotating shaft 14 to rotate around their axes. The function of the wind farm component is to generate a wind field. The wind farm component includes a third frame 21 and multiple fan components 22. The third frame 21 includes a frame body and multiple support rods 211. Multiple mounting holes 213 are provided inside the frame body, and the support rods 211 are installed within the mounting holes 213. Each fan component 22 is connected to each... Support rods 211 are connected one-to-one. The third frame 21 is externally fixedly connected to the second rotating shaft 14, allowing the third frame 21 to rotate around the axis of the second rotating shaft 14. This allows the third frame 21 to adjust its angle under the action of the first rotating shaft 13 and the second rotating shaft 14. Multiple mounting holes 213 are provided within the frame body, and a support rod 211 is installed in each mounting hole 213. Each fan component 22 is connected one-to-one with each support rod 211. That is, the number of mounting holes 213 is the same as the number of fan components 22. Optionally, a moving component is added, installed at the bottom of the first frame 11, to facilitate movement of the device. In this technical solution, through the first... Multiple fan components 22 are installed within the three-frame 21. The rotation of the fan components 22 generates a wind field. The lateral and longitudinal angles of the wind field components are adjusted by the first frame 11, the second frame 12, the first rotating shaft 13, and the second rotating shaft 14. At the same time, the wind speed and wind direction are changed by adjusting the rotation angle and rotation speed of different fan components 22, thereby generating complex multi-dimensional wind speed changes in the wind field. Furthermore, wind speed and wind tunnel tests can be conducted outdoors, eliminating the influence of existing wind tunnel boundary effects and scaling effects on wind field testing. Moreover, the wind speed generation mode can be formed by negative pressure intake or positive pressure wind delivery according to the orientation of the fan components 22, thereby achieving the technical effect of improving the applicability of the wind field.

[0030] Furthermore, the frame body includes an outer frame 2111 and a bracket. The bracket includes a transverse bracket 2112 and a longitudinal bracket 2113. The transverse bracket 2112 and the longitudinal bracket 2113 are arranged to cross each other and form a plurality of mounting holes 213. The two ends of the support rod 211 are connected to the transverse bracket 2112 and the longitudinal bracket 2113. In this embodiment, the frame body is further defined, and a bracket is provided inside the outer frame 2111. The bracket is composed of multiple horizontal brackets 2112 and vertical brackets 2113. The horizontal brackets 2112 and vertical brackets 2113 are arranged perpendicularly to each other and form multiple mounting holes 213. Furthermore, the horizontal brackets 2112 and vertical brackets 2113 are arranged in a rectangular or circular row. The fan component 22 adopts a modular design. The number of support rods 211 is one or two. When there is one support rod 211, the fan component 22 is installed in the middle position of the support rod 211. When there are two support rods 211, the two support rods 211 are arranged crosswise, and the fan component 22 is installed at the intersection of the two support rods 211, so that the position of the fan component 22 is fixed.

[0031] Furthermore, each fan component 22 includes a motor, a bearing, a shaft, and a fan. The outer side of the bearing is fixed and passes through the support rod 211. The shaft passes through the bearing, the motor is connected to one end of the shaft, and the fan is connected to the other end of the shaft. In this embodiment, the fan component 22 is further defined. The bearing is mounted on the support rod 211, and the axis of the bearing is perpendicular to the support rod 211. The shaft is installed inside the bearing, the motor is fixed on the support rod 211, the output end of the motor is fixedly connected to the shaft, and the fan is located at the other end of the shaft. When the motor is powered on, it rotates, which can drive the fan to rotate.

[0032] Furthermore, a power supply component is provided, comprising a power supply device and connecting cables. The power supply device is connected to the connecting cables, which in turn are connected to each fan component 22. In this embodiment, a power supply component is added. The power supply device uses an existing battery or AC power source. The power supply device supplies power to each fan component 22 via the connecting cables. Moreover, the rotation speed of each fan component 22 can be adjusted as needed, thereby achieving the technical effect of convenient power supply.

[0033] The specific wind field formation is as follows:

[0034] First, the one-dimensional wind speed direction is changed through a vector array-type multi-stage dynamic wind tunnel, such as... Figure 2 As shown, the third frame 21 rotates about the y-axis, while the second frame 12 does not rotate about the x-axis. Figure 3 As shown, the second frame 12 rotates around the x-axis, while the first frame 11 does not rotate around the y-axis, resulting in a one-dimensional change in wind speed direction.

[0035] Second, the two-dimensional wind speed direction changes in a vector array-type multi-stage dynamic wind tunnel, such as... Figure 4 As shown, the first frame 11 rotates around the y-axis and the second frame 12 rotates around the x-axis, resulting in a change in the two-dimensional wind speed direction.

[0036] Third, multi-stage power units can be used in combination, such as Figure 5 As shown, multiple power units are arranged and combined according to the required positions to form a high-dimensional matrix wind tunnel. Among them, the first power unit 51, the second power unit 52, the third power unit 53 and the fourth power unit 54 are placed according to the set positions, which can generate complex high-dimensional wind speed changes, such as simulating the dynamic processes of tornado and typhoon formation and migration.

[0037] Fourth, corridor-type wind tunnels can be formed based on existing building corridors, thereby saving costs and allowing wind tunnel tests to be conducted outdoors, thus eliminating the influence of existing wind tunnel boundary effects and scaling effects on wind field testing.
