[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a device for testing the performance of UAV blades, comprising a fixed base 1, a support block 2 fixedly connected to the upper surface of the fixed base 1, a placement shell 3 slidably connected to the upper surface of the support block 2, a load-bearing frame 4 fixedly connected inside the placement shell 3, a cylinder 5 fixedly connected inside the load-bearing frame 4, a base plate 6 fixedly connected to the output end of the cylinder 5, a support frame 7 fixedly connected to the upper surface of the base plate 6, a rotating block 8 rotatably connected inside the support frame 7, a fixed frame 9 rotatably connected to the outer wall of the rotating block 8, a clamp 10 fixedly connected to the upper surface of the fixed frame 9, a fixed plate 11 slidably connected to the inner wall of the fixed frame 9, a lower surface of the fixed plate 11 fixedly connected to the upper surface of the cylinder 5, a blade body 33 slidably connected to the outer wall of the clamp 10, and a drive assembly disposed inside the support block 2.

[0025] Specifically, support block 2 supports housing 3, load-bearing frame 4 is fixed inside housing 3 to fix cylinder 5, ensuring cylinder 5's stability, cylinder 5 fixes base plate 6, base plate 6 fixes support frame 7, support frame 7 and fixed frame 9 support rotating block 8, rotating block 8 causes fixed frame 9 to move clamp 10, cylinder 5 fixes fixed plate 11, fixed plate 11 supports and limits the offset of fixed frame 9, so that fixed frame 9 can only slide on the upper surface of fixed plate 11, base plate 6 has four support frames 7 on the upper surface, and then four rotating blocks 8 and fixed frames 9 respectively, the four fixed frames 9 drive the four clamps 10 to move, can clamp and fix blade body 33, can adapt to blade body 33 of different sizes, and can also keep blade body 33 in the center position, ensuring the accuracy of detection.

[0026] Reference Figure 2 The drive assembly includes a motor 12, the outer wall of which is fixedly connected to the inside of the support block 2. A rotating shaft 13 is fixedly provided at the output end of the motor 12. The outer wall of the rotating shaft 13 is rotatably connected to the inside of the support block 2 and fixedly connected to the inside of the housing 3.

[0027] Specifically, the support block 2 fixes the motor 12, and the rotating shaft 13 fixes the housing 3. Starting the motor 12 will drive the rotating shaft 13 to rotate, which in turn drives the housing 3 to rotate, thereby driving the blade body 33 to rotate, so that the blade body 33 can be rotated while performing performance testing.

[0028] Reference Figure 4 and Figure 5The fixed base 1 has a sliding block 14 inside, a motor 15 inside the sliding block 14, a rotating column 16 fixedly installed at the output end of the motor 15, a fixed block 17 rotatably connected to the outer wall of the rotating column 16, a load-bearing block 22 fixedly connected to the lower surface of the fixed block 17, and the outer wall of the load-bearing block 22 fixedly connected to the inside of the fixed base 1. The fixed base 1 also has a sliding block 18 inside, a motor 19 inside the sliding block 18, a threaded column 20 fixedly installed at the output end of the motor 19, the outer wall of the threaded column 20 threadedly connected to the inside of the fixed block 17, a fixed plate 21 fixedly connected to the outer wall of the load-bearing block 22, and the outer wall of the fixed plate 21 slidably connected to the inner wall of the rotating column 16.

[0029] Specifically, the fixed base 1 provides support and limits the movement of sliding blocks 14 and 18, ensuring that they can only move within the fixed base 1 and will not detach from it. Two circular plates are provided on the outer wall of the rotating column 16. These plates limit the movement of the fixed disk 21, preventing it from shifting. Simultaneously, when the fixed disk 21 moves, the circular plates cause the rotating column 16 to slide within the fixed block 17, which in turn supports the rotating column 16. The fixed block 17 supports the threaded column 20. When the motor 3 19 drives the threaded column 20 to rotate inside the fixed block 17, the threaded column 20 will move through the thread action, thereby driving the fixed disk 21 to move. At the same time, the motor 3 19 will follow the threaded column 20 through the sliding block 2 18. When the fixed disk 21 drives the rotating column 16 to move inside the fixed block 17, the sliding block 14 will move inside the fixed seat 1, so that the rotating column 16 and the fixed disk 21 will not get stuck.

[0030] Reference Figure 4 and Figure 5 The rotating column 16 is rotatably connected to a turntable 23. The outer wall of the turntable 23 is slidably connected to a bracket 24. The inner wall of the bracket 24 is rotatably connected to a connecting column 25. The outer wall of the connecting column 25 is fixedly connected to a nozzle 26. The inner wall of the connecting column 25 is rotatably connected to a support column 34. The lower surface of the support column 34 is fixedly connected to the inside of the load-bearing block 22.

[0031] Specifically, the rotating column 16 supports the turntable 23, and its rotation causes the turntable 23 to rotate simultaneously. The bracket 24 provides a limiting offset for the turntable 23, ensuring that the turntable 23 can only rotate within the inner wall of the bracket 24. The connecting column 25 supports the bracket 24, and its movement causes the turntable 23 to move simultaneously. The movement of the rotating column 16 changes the fit between it and the turntable 23. When the fit decreases, the turntable 23 will rotate more due to the limiting effect of the bracket 24. When the fit decreases again, the turntable 23 will return to its normal rotation range. The support column 34 provides support and limiting offset for the connecting column 25, ensuring that the connecting column 25 can only rotate within the outer wall of the support column 34. Simultaneously, the rotation range of the turntable 23 is transmitted to the connecting column 25 through the bracket 24, which in turn causes the connecting column 25 to change the oscillation range of the nozzle 26, further adjusting the air humidity and orientation of the simulated airflow.

[0032] Reference Figure 1 and Figure 5 The load-bearing block 22 is internally fixedly connected to a motor 30, and the output end of the motor 30 is fixedly provided with a rotating shaft 31. The outer wall of the rotating shaft 31 is fixedly connected to a fan blade 32.

[0033] Specifically, the load-bearing block 22 has a fixing effect on the motor 30, and the motor 30 has a fixing effect on the rotating shaft 31. When the rotating shaft 31 rotates, it will drive the fan blade 32 to rotate at the same time. The rotation of the fan blade 32 can simulate airflow. At the same time, through the cooperation of the fan blade 32 and the nozzle 26, various environmental conditions can be simulated.

[0034] Reference Figure 1 and Figure 5 A water tank 27 is connected to the upper surface of the fixed base 1. A water pump 28 is fixedly connected inside the water tank 27. A hose 29 is fixedly connected to the output end of the water pump 28. The outer wall of the hose 29 is fixedly connected to the inside of the nozzle 26.

[0035] Specifically, the mounting base 1 has a fixing function for the water tank 27. Starting the water pump 28 can allow the water inside the water tank 27 to enter the nozzle 26 through the hose 29, which facilitates the water source conditions for the nozzle 26 to spray.

[0036] Working principle: When the device is needed, place the blade body 33 on the upper surface of the clamp 10, and then start the cylinder 5. The output end of the cylinder 5 will drive the base plate 6 to move. When the base plate 6 moves, it will drive the support frame 7 to move. When the support frame 7 moves, it will cause the rotating block 8 to move and rotate. During the rotation of the rotating block 8, it will drive the fixed frame 9 to make the clamp 10 slide on the outer wall of the fixed plate 11. When the clamp 10 moves inward, it will clamp and fix the blade body 33 and keep the blade body 33 in the center position, ensuring the accuracy of the blade body 33 during testing, and enabling the blade body 33 to be quickly disassembled and replaced.

[0037] After the blade body 33 is clamped and fixed, motor 215 is started. Motor 215 drives the rotating column 16 to rotate inside the fixed block 17. The rotation of the rotating column 16 also drives the turntable 23 to rotate. When the turntable 23 rotates, it slides on the inner wall of the bracket 24 and drives the bracket 24 to rotate on the outer wall of the connecting column 25. At the same time, during the rotation of the turntable 23, the connecting column 25 is also driven to rotate left and right on the outer wall of the support column 34 through the bracket 24, so that the nozzle 26 can spray at multiple angles. Then, motor 319 is started. Motor 319 drives the threaded column 20 to rotate and move inside the fixed block 17 through the thread action. When the threaded column 20 moves, it drives the fixed disk 21 to move. The fixed disk 21 drives the rotating column 23 to rotate. The moving column 16 moves inside the fixed block 17. When the moving column 16 moves, it drives the turntable 23 to move. When the turntable 23 moves and rotates, the rotation amplitude will increase due to the limitation of the bracket 24. In turn, the bracket 24 drives the swing amplitude of the connecting column 25 to increase, which further increases the swing amplitude of the nozzle 26 to achieve the regulation of air humidity. Then, the motor 30 is started, which drives the rotating shaft 31 to rotate, causing the fan blade 32 to rotate. This allows for wind speed performance testing of the blade body 33. This device can not only quickly clamp and fix the blade body 33, making it easy to replace and ensuring centering stability, thus improving testing efficiency, but also simulate and adjust the humidity and wind speed of the airflow during testing to adapt to different testing needs.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
