[0024] See also Figures 1-4 As shown, the automatic detection device of the wind speed measuring instrument for mining includes a wind tube 1, a motor 2 is fixedly installed below the front end of the outer surface of the wind tube 1, a support frame 101 is fixedly installed on the lower surface of the wind tube 1, a fixing sleeve 202 is fixedly installed on the front end of the lower surface of the support frame 101, the fixing sleeve 202 is sleeved and installed on the outer surface of the motor 2, a transmission gear 201 is fixedly installed on the output end of the motor 2, a fan 3 is fixedly installed on the rear end of the inner surface of the wind tube 1, and an adjustment ring 4 is movably connected to the front end of the outer surface of the wind tube 1;

[0025] A docking groove 401 is provided at the rear end of the outer surface of the adjusting ring 4. A plurality of meshing teeth 402 are evenly fixed on the outer ring surface of the adjusting ring 4. The meshing teeth 402 are engaged with the transmission gear 201. A wind speed sensor assembly 5 is fixedly installed above the inner bottom surface of the adjusting ring 4. A fixing seat 403 is fixedly provided in the middle of the inner bottom surface of the adjusting ring 4. The upper surface of the fixing seat 403 is fixedly connected to the lower surface of the wind speed sensor assembly 5.

[0026] An anemometer 7 is fixedly mounted below the inner top surface of the adjusting ring 4. Fixed clips 601 are sleeved and mounted on both sides of the outer surface of the anemometer 7. A two-way bolt 602 is screwed through one side of the outer surface of the fixing clip 601. A guide rail 6 is movably mounted on the upper surface of the fixing clip 601. The upper surface of the guide rail 6 is fixedly connected to the middle part of the inner top surface of the adjusting ring 4. An anemometer 9 is fixedly mounted in the middle part of the inner surface of the adjusting ring 4. A monitoring probe 10 is fixedly mounted on the front end of the anemometer 9.

[0027] A fixing ring 801 is fixedly mounted on the outer surface of the anemometer 9, and a fixing rod 8 is fixedly mounted in the middle of both sides of the outer surface of the fixing ring 801. Both ends of the fixing rod 8 are fixedly connected to the middle of both sides of the inner surface of the adjustment ring 4. A fixing plate 802 is fixed in the middle of the front end of the outer surface of the fixing rod 8, and one side of the outer surface of the fixing plate 802 is fixedly mounted and connected to the monitoring probe 10.

[0028] When the utility model is in use, the wind speed sensor assembly 5 can be first installed and connected with the fixing seat 403, thereby completing the installation and fixation between the wind speed sensor assembly 5 and the adjusting ring 4, and at the same time, the anemometer 7 is inserted into the gap between the fixing clamps 601, and the two-way bolt 602 is turned clockwise to control the fixing clamps 601 to move laterally together along the guide rail 6, thereby completing the clamping and fixation of the anemometer 7. At this time, the fan 3 can be started to perform wind speed measurement and calibration monitoring;

[0029] When the fan 3 is in the starting state, it will blow air into the interior of the wind tube 1. At this time, the wind force will be transmitted through the wind tube 1 and contact the wind speed sensor assembly 5, the anemometer 7 and the anemometer 9. In this case, the wind speed sensor assembly 5, the anemometer 7 and the anemometer 9 can measure the wind speed and display the value. At this time, the wind speed value displayed by the wind speed sensor assembly 5, the anemometer 7 and the anemometer 9 can be read by the monitoring probe 10, and the calibration personnel can check the value to determine the accuracy of the test, thereby completing the wind speed measurement test of the wind speed sensor assembly 5 and the anemometer 7 to ensure its accuracy and stability during use;

[0030] Secondly, during the wind speed measurement and calibration process of the wind speed sensor assembly 5 and the anemometer 7, after obtaining the first batch of wind speed measurement data, the motor 2 can be controlled to start, and the transmission gear 201 can be controlled to rotate by rotating the output end of the motor 2. Since the transmission gear 201 and the meshing teeth 402 set on the outer ring surface of the adjustment ring 4 are in a meshing state, the adjustment ring 4 can be controlled to rotate by rotating the transmission gear 201, so that the wind speed sensor assembly 5 and the anemometer 7 are controlled by the rotation of the adjustment ring 4 to adjust the measurement orientation. After adjusting the measurement orientation, the fan 3 is started again to obtain the second batch of wind speed measurement data, and the inspection personnel check the data to determine the accuracy of the inspection, thereby completing the wind speed calibration of the wind speed sensor assembly 5 and the anemometer 7 at different measurement orientations to ensure the accuracy of the measurement results and be suitable for use in complex measurement orientations within the mine.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
