DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

An installation seat 3 is provided on the bottom plate 2. At least two clamps 4 are provided on the installation seat 3. The clamps 4 are used to clamp the base 51 of the wind speed sensor 5, fixedly clamping the measured wind speed sensor 5 to prevent the wind speed sensor 5 from colliding and generating noise due to inclination or shaking during the test. The clamp 4 in this embodiment is a vertical quick clamp, which can quickly clamp and disassemble the wind speed sensor 5.

[0023] Reference Figure 3 and Figure 4 , a sliding seat 9 is provided at the top of the box body 1. A slider 81 slidably connected to the sliding seat 9 in the vertical direction is provided on the sliding seat 9. The slider 81 is fixedly connected to a bracket 8. A servo motor 6 is fixedly installed on the bracket 8. The servo motor 6 is slidably connected to the sliding seat 9 in the vertical direction through the slider 81. A positioning screw 10 for positioning the slider 81 on the sliding seat 9 is provided on the slider 81. The positioning screw 10 is threadedly connected to the slider 81. A pressing block is provided at the contact end of the positioning screw 10. The pressing block of the positioning screw 10 presses tightly against the sliding seat 9, enabling the positioning of the slider 81 on the sliding seat 9. A side plate that can be opened is provided on the side of the box body 1 to facilitate the adjustment of the positioning screw 10.

[0024] The output shaft of the servo motor 6 is fixedly connected to a coupling member 7. The coupling member 7 is vertically arranged. A locking member 71 is provided at the lower end of the coupling member 7. The locking member 71 is used to engage with the rotating part 52 of the wind speed sensor 5, so that the coupling member 7 and the rotating part 52 of the wind speed sensor 5 can rotate synchronously. Reference Figure 5 , the wind speed sensor 5 in this embodiment is a cup anemometer. The locking member 71 is provided with three insertion blocks, and the insertion blocks can be inserted between the wind cup rods of the rotating part of the wind speed sensor 5 to form no relative rotation between the coupling member 7 and the wind speed sensor 5.

[0025] After installing the wind speed sensor 5 on the installation seat 3, adjust the position of the servo motor 6 in the vertical direction so that after the locking member 71 of the coupling member 7 is engaged with the rotating part 52 of the wind speed sensor 5, the servo motor 6 can drive the rotating part 52 of the wind speed sensor 5 to rotate. The wind speed sensor 5 senses the rotation of the wind cups on its own rotating part 52, and can obtain the rotation speed of the rotating part 52. By comparing the rotation speed of the wind speed sensor 5 and the rotation speed of the servo motor 6, the accuracy of the wind speed sensor 5 is detected.

[0026] It should be noted that through the servo motor 6 in this device, any extreme wind speed data can be simulated, and the maximum wind speed that can be simulated is 100 m per second, enabling the wind speed sensor 5 to complete the test of extreme wind speed data indoors.

[0027] Reference Figure 2 and Figure 3, a door panel 11 is provided on the front of the box body 1. The door panel 11 can be opened and closed. The position of the door panel 11 corresponds to the installation position of the wind speed sensor 5, which facilitates the removal and installation of the wind speed sensor 5. A magnetic control switch 15 is provided between the door panel 11 and the box body 1. The magnetic control switch 15 is used to control the power supply of the entire device. After the door is closed, the magnetic control switch 15 connects the power supply to prevent test operations from being performed when the door panel 11 is in the open state, which is beneficial to safe operation.

[0028] Reference Figure 2 , a start switch 12, a speed regulation display panel 13, and a speed regulation switch 14 are provided on the outside of the box body 1. The start switch 12 is used to turn on this wind speed simulation tester. The speed regulation display panel 13 is used to display the rotation speed of the servo motor 6. The speed regulation switch 14 is used to adjust the rotation speed of the servo motor 6.
