[0002] Wind speed and direction sensors have a wide range of applications. In the agricultural field, they are used to monitor meteorological conditions, help farmers predict weather changes and make corresponding planting plans. In the field of meteorological monitoring, wind speed and direction sensors are an important part of meteorological stations, providing important data for weather forecasting and climate research. However, wind speed and direction sensors need to be calibrated before use to ensure the accuracy of the monitoring data.

[0003] Application No. 202221487624.7 A wind speed sensor calibration device comprises a ventilation duct, a fan and a wind speed sensor, wherein a wind speed regulator is connected above the fan, a placement opening is opened on the upper side wall of the ventilation duct, the wind speed sensor is placed and fixed on the placement opening by a locking bolt, a wind vane is provided at the air outlet of the ventilation duct, and a storage box for storing the ventilation duct, the wind speed sensor and the wind vane is provided below the ventilation duct, a clamping mechanism for fixing the ventilation duct and the wind vane is installed at the upper end of the storage box, and a moving component for moving the storage box is provided at the lower end of the storage box; the ventilation duct and the wind vane are firmly clamped by the clamping mechanism to maintain the stability and uniformity of the airflow passing through the duct, and after the wind speed sensor is calibrated, the ventilation duct, the wind speed sensor and the wind vane are all stored in the storage box, and the moving component makes the storage box easy to move, so as to achieve the effect of convenient storage and carrying of the device.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] As attached Figure 1 To Attachment Figure 5 As shown: a wind direction and wind speed sensor calibration device includes a ventilation duct 1, a wind vane 2 is installed on the inner wall of the ventilation duct 1, a fan 3 is installed on the inner wall of the ventilation duct 1, the fan 3 is located on the left side of the wind vane 2, and a control panel 4 is installed on the front of the ventilation duct 1. The control panel 4 and the wind vane 2 are connected by a wire, and the measurement data of the wind vane 2 will gradually be fed back to the control panel 4. The staff can view the measurement data more intuitively, thereby facilitating the staff to calibrate the wind speed sensor body 502.

[0024] A sensor fixing assembly 5 is installed on the top of the ventilation duct 1. The sensor fixing assembly 5 includes a fixing tube 501 fixedly embedded in the top of the ventilation duct 1. A wind speed sensor body 502 is arranged inside the fixing tube 501. The outer surface of the wind speed sensor body 502 is fixedly connected with a ring-arranged support plate 503. A plug hole 504 is opened on the upper surface of each support plate 503. A plug column 505 is inserted into the inner wall of each plug hole 504. The bottom end of each plug column 505 is fixedly connected with a frame plate 506. The ends of each group of frame plates 506 away from each other are connected to the inner wall of the fixing tube 501. When the plug column 505 is inserted into the plug hole 504, the wind speed sensor body 502 will be stabilized inside the fixing tube 501, and the wind speed sensor body 502 will be located directly above the wind vane 2. The distances between the wind vane 2 and the wind speed sensor body 502 and the fan 3 are the same, so the wind speed values ​​measured by the two will be the same, thereby effectively avoiding errors in the calibration of the wind speed sensor body 502.

[0025] An annular groove 507 is provided on the upper surface of the fixed cylinder 501, and an annular frame 508 is clamped on the inner wall of the annular groove 507. A sealing cover 509 is fixedly connected to the upper surface of the annular frame 508. By clamping the annular frame 508 and the annular groove 507, the sealing cover 509 can be stabilized on the top of the fixed cylinder 501, and a sealing effect can be achieved on the top of the fixed cylinder 501 to prevent gas flow in the fixed cylinder 501 when the fan 3 is working, thereby avoiding interference with the wind speed at the wind speed sensor body 502, thereby ensuring accuracy during measurement.

[0026] The inner top wall of the sealing cover 509 is fixedly connected with a pillar 510, and the bottom end of the pillar 510 is fixedly connected with a pressure pad 511. The bottom surface of the pressure pad 511 contacts the upper surface of the wind speed sensor body 502. When the sealing cover 509 is stabilized on the top of the fixed tube 501, the pressure pad 511 will contact the top of the wind speed sensor body 502 and will form pressure on the wind speed sensor body 502, thereby ensuring the stability of the wind speed sensor body 502 to prevent the wind speed sensor body 502 from shaking, thereby ensuring the accuracy during calibration.

[0027] A wind direction calibration component 6 is installed on the upper left side of the ventilation tube 1, and the wind direction calibration component 6 includes a cylinder 601 fixedly connected to the upper surface of the ventilation tube 1, and two groups of ventilation holes 602 are opened on the outer surface of the cylinder 601. A clamp 603 is fixedly connected to the bottom surface of the cylinder 601, and a sealing plate 604 is clamped on the top of the cylinder 601. There are four ventilation holes 602, and the angle between each two adjacent ventilation holes 602 is ninety degrees. The clamp 603 is used to facilitate the staff to fix the wind direction sensor, and the sealing plate 604 can seal the top of the cylinder 601 to prevent gas flow, which is convenient for the staff to calibrate the wind direction sensor.

[0028] Two filter screens 7 are fixedly connected to the inner wall of the ventilation duct 1, and annular plates 8 are clamped on the inner walls of the left and right ends of the ventilation duct 1. The filter screens 7 can be used to shield the left and right ends of the ventilation duct 1 to prevent dust and debris from entering the interior of the ventilation duct 1 and affecting the calibration work. At the same time, the annular plates 8 can be used to seal the two ends of the ventilation duct 1 when not in use to prevent damage to the internal equipment.

[0029] Working principle: When the wind speed sensor body 502 needs to be calibrated, the wind speed sensor body 502 can be inserted into the fixed tube 501, and the plug 505 is connected to the socket 504. The wind speed sensor body 502 will be located directly above the wind vane 2, and the distance between the wind speed sensor body 502 and the wind vane 2 and the fan 3 is the same. Then the annular frame 508 on the sealing cover 509 is inserted into the annular groove 507, and the sealing cover 509 will seal the top of the fixed tube 501. At the same time, the pressure pad 511 will press and stabilize the wind speed sensor body 502, and then start the fan 3. The wind resistance between the wind speed sensor body 502 and the wind vane 2 and the fan 3 is the same. The wind speed sensor body 502 can be calibrated according to the measurement value of the wind vane 2 to avoid errors during calibration.
