The wind direction sensor can use an adapter that integrates "digital transmission", "communication" and "charging" to achieve equipment installation, data collection and transmission. However, the use of a robot to achieve automated batch calibration also faces the following technical difficulties: First, the tail wing fixings must be modified on the existing adapter; second, the problem of the disordered angle between the wind direction sensor aviation plug positioning slot and the wind direction zero position must be solved; third, the position of the wind vane tail wing must be fixed to ensure that the wind direction sensor angle output is 15° when starting the wind speed project. Summary of the invention

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a fixing device for calibrating a wind direction sensor. The modified adapter provides the hardware conditions for fully automatic calibration of the wind direction sensor in the wind tunnel chamber and automatic grasping and fixing of the sensor by a manipulator, and can be used for an automated batch calibration line for wind direction sensors.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A fixing device for wind direction sensor calibration, comprising a cylindrical housing adapter and a support rod assembly; the cylindrical housing adapter comprises a main body, a plug female head for connecting a plug male head of a wind direction sensor is arranged in the middle of the upper end of the main body, a wind direction data collector for collecting wind direction sensor data through the plug female head is also arranged in the main body, and a connecting part for connecting the wind direction sensor is arranged at the upper end of the main body; a wind direction angle display for displaying the wind direction output value in real time is also arranged on the main body; the support rod assembly comprises a fixing ring, a support rod, an adjusting rod and a tail bracket; the fixing ring is mounted on the annular groove of the main body, a locking device is arranged on the fixing ring, the fixing ring can be rotated on the main body and the rotating position is locked by the locking device; the support rod is used to connect the fixing ring and the adjusting rod; the adjusting rod adjusts the height of the tail bracket so that the tail bracket clamps the wind direction sensor at the benchmark position of the wind direction sensor when the wind direction sensor is in a non-calibration state, so that the tail bracket is separated from the benchmark position of the wind direction sensor when the wind direction sensor is in a calibration state.

[0006] The adjusting rod is an electric telescopic rod.

[0007] An annular groove is arranged on the main body, and a fixing ring of the support rod assembly is installed in the annular groove.

[0008] The fixing ring has an opening, locking ear plates are arranged on both sides of the opening, and fastening screws are arranged on the locking ear plates.

[0009] A slot is provided on the tail wing bracket, and the wind direction sensor pole is fixed in the slot.

[0011] A wireless communication module is also arranged inside the main body, and the wireless communication module sends the data collected by the collector to the computer terminal by wireless transmission.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The sensor without an adapter needs to be manually installed in the wind tunnel chamber, because there is an aviation plug under the wind direction sensor that needs to be aligned and installed, and the conditions for the robot to automatically grab and install it are not met. The utility model fixes the wind direction sensor through a cylindrical shell adapter; the adapter with the wind direction sensor installed is placed on the tooling plate of the conveyor belt, and the robot can grab the wind direction sensor by grabbing the adapter, realizing the automatic calibration of the wind direction sensor in the whole process, reducing the manual operation links as much as possible, and greatly improving efficiency.

[0014] 2. Installing the sensor on the adapter solves the problems of early installation of the sensor, data collection, and the difficulties of different sensor models and specifications.

[0015] 3. The modified adapter has an automatically rising and falling tail wing fixing component, which can realize automatic control of the wind direction sensor benchmark, solve the problem of disordered angle between the wind direction sensor aviation plug positioning slot and the wind direction zero position, and provide the hardware conditions for the wind direction sensor to enter the wind tunnel for automatic calibration.

[0016] 4. Based on the design of the meteorological sensor automatic calibration system (3MS), it meets the unified management requirements of calibration data and lays the foundation for the automatic transmission, upload and storage of calibration / calibration data in the later stage. The research and development of the wind direction sensor automatic calibration device will significantly improve the measurement automation detection capability and the laboratory automation and information level, which is of great significance. At the same time, the device also has good scalability and can be extended to ultrasonic wind sensors in the later stage, with broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
