[0038] In this embodiment, the multiple rotating shafts include a first rotating shaft 305 and multiple second rotating shafts 308. The first driving member 304 is a first motor. The output shaft of the first motor is connected to the first rotating shaft 305 to drive the first rotating shaft 305 to rotate.

The above-mentioned limit structure is adopted, which not only facilitates the staff to place and take the placement component 3, so as to facilitate the staff to quickly replace the ultrasonic anemometer, further improves the work efficiency, but also can make the placement component 3 fixed in position during the detection process, make the operation more convenient and simple, reduce human interference and errors, and improve work efficiency.

[0042] The limiting plate 206 can be movably arranged, including the limiting plate 206 moving horizontally or vertically, or swinging relative to the workbench 1, and then cooperating with the fixing plate 301 in a limiting manner.

[0043] like Figure 4 As shown, there are two limit plates 206, and the two limit plates 206 are movably arranged in the transverse direction. The two limit plates 206 can approach and move away from each other, and the two limit plates 206 are respectively matched with the two sides of the fixed plate 301. With the above-mentioned limiting method, the two limit plates 206 are brought close to each other and can contact the fixed plate 301, thereby limiting the fixed plate 301. The two limit plates 206 are moved away from each other and can be separated from the fixed plate 301, thereby facilitating the removal of the fixed plate 301.

[0044] like Figure 4As shown, the limit assembly 2 also includes a second driving member 201, a screw and two threaded caps 204.

The second driving member 201 is drivingly connected to the screw to rotate the screw. With the above-mentioned driving method, since the first thread 202 and the second thread 203 have opposite rotation directions, when the second driving member 201 drives the screw to rotate, the two threaded caps 204 can move in opposite directions, thereby realizing the two limit plates 206 approaching and moving away from each other.

[0045] In this embodiment, a connecting rod 205 is provided on the threaded cap 204 , and a limiting plate 206 is connected to the upper end of the connecting rod 205 .

[0046] Among them, a transmission chamber 101 is opened inside the workbench 1, the second driving member 201 is a first motor, the first motor is fixed to the inner wall of the transmission chamber 101, one end of the screw is connected to the output shaft of the first motor, and the other end of the screw is rotatably connected to the inner wall of the transmission chamber 101 through a bearing.

[0047] like Figure 4 As shown, the air outlet assembly 4 includes a fan 401, a connecting pipe 403, a diverter plate 406 and a plurality of air outlet pipes 409. The fan 401 has a fan inlet and a fan outlet. The connecting pipe 403 is connected to the fan outlet. The connecting pipe 403 has a plurality of connecting outlets. A plurality of partitions 407 are arranged in the diverter plate 406. The plurality of partitions 407 divide the diverter plate 406 into a plurality of buffer chambers. The plurality of connecting outlets are connected to the inlets of the plurality of buffer chambers in a one-to-one correspondence. The plurality of air outlet pipes 409 are connected to the outlets of the plurality of buffer chambers in a one-to-one correspondence. The air outlets are arranged on the air outlet pipes 409. With the above-mentioned air outlet assembly 4, wind is generated by the fan 401. The wind flows into the plurality of buffer chambers of the diverter plate 406 through the connecting pipe 403, and then flows out through the plurality of air outlet pipes 409 and blows toward the corresponding anemometer.

[0048] In this embodiment, an air inlet pipe 402 is provided at the fan inlet of the fan 401 .

[0049] like Figure 4 As shown, the air outlet component 4 also includes an electric push rod 404 and a second support plate 405. The lower end of the electric push rod 404 is connected to the workbench 1, and the upper end of the electric push rod 404 is connected to the second support plate 405. The diverter plate 406 is arranged on the second support plate 405. By adopting the above-mentioned air outlet component 4, the electric push rod 404 can be used to drive the second support plate 405 to move vertically, and then the diverter plate 406 and the air outlet pipe 409 can be moved vertically to adjust the relative height of the air outlet pipe 409 and the anemometer to make the test results more accurate.

[0050] The connecting pipe 403 is a spring hose.

[0051] In this embodiment, the air outlet assembly 4 further includes a plurality of valves 408 disposed on the connecting pipe 403, and the plurality of valves 408 are disposed one by one in correspondence with the plurality of buffer chambers. The valves 408 can be used to adjust the connection state between the buffer chamber and the connecting pipe 403, thereby controlling the air outlet state of the air outlet pipe 409.

[0052] Among them, by setting the connecting pipe 403, the diverter plate 406 and the air outlet pipe 409, and the position of the air outlet pipe 409 corresponds to the position of the anemometer, not only can the performance of each anemometer be clearly distinguished to avoid confusion or cross-interference, which is beneficial for the staff to accurately evaluate the performance of each device, but also it can ensure that the test data of each anemometer is independent, which is beneficial for verifying the accuracy and stability of each device and ensuring the reliability of the test results. At the same time, the partition 407 is used to divide the inside of the diverter plate 406 into multiple buffer chambers, which can smooth the wind output from the connecting pipe 403 inside the buffer chamber, avoiding errors caused by sudden changes in wind speed, thereby reducing measurement errors, accurately measuring the propagation time and angle of ultrasonic signals, and thus improving the accuracy of measurements.

Using the above detection method, the actual performance of the ultrasonic anemometer can be accurately evaluated by controlling the wind speed accurately and comparing the detection result with the preset wind speed to ensure that it meets the specified standards and requirements. At the same time, by fixing and rotating the ultrasonic anemometer, it can be ensured that the anemometer remains stable during the detection process to avoid the influence of external interference on the test results.

[0054] Specifically, firstly, the ultrasonic anemometer is placed on the surface of the placement plate 3061, and the ultrasonic anemometer is fixed by the telescopic rod 3063, the spring and the clamping plate 3064, and then the fixing plate 301 fixed with multiple ultrasonic anemometers is overlapped in the placement groove 311. Then, the second driving member 201 is controlled by the control device to operate, the second driving member 201 drives the screw to rotate, and the screw drives the threaded cap 204 to move, thereby driving the connecting rod 205 and the limiting plate 206 fixed on the surface of the threaded cap 204 to move synchronously. When the limiting plate 206 is clamped in the limiting groove on the surface of the fixing plate 301, the control device controls the second driving member 201 to stop operating. Finally, the control device controls the operation of the fan 401 and adjusts the wind speed to a specified size, and then discharges the wind from the air outlet 409. The anemometer detects the wind speed and compares the detection result with the preset wind speed. During the detection process, the control device controls the operation of the first driving member 304 to drive the first rotating shaft 305 to rotate. The first rotating shaft 305 drives the anemometer placement table 306 fixed at its upper end to rotate, thereby driving the anemometer to rotate, and then detecting the wind direction at different angles in the horizontal direction. At the same time, when the first rotating shaft 305 rotates, it drives the driving wheel 307 to rotate, and with the cooperation of the transmission chain 310, it drives the driven wheel 309 to rotate, and then drives multiple anemometers to rotate at the same time.
