A hose 47 is connected to the flow control valve 46. An air detection sensor and a wireless communication WIFI module are set between the upper sealing plate 493 and the fixed ring 492.

[0048] The calibration mechanism also includes a solenoid valve 48, a wire feeding reel 49, a servo motor 491, and a second drive motor 494.

[0049] The flexible hose 47 is wound around the wire feeding reel 49, which is fixedly connected to the inside of the movable circular tube 32 by a connecting block. The first fixed circular ring 41 is rotatably connected to the outside of the fixed circular rod 31. The flexible hose 47 passes through the second movable plate 37 and is connected to the solenoid valve 48. The fixed circular plate 492, the upper sealing plate 493, the fixed arc plate 497, and the rotating arc plate 498 form a sealing cavity. A pressure sensor is installed in the sealing cavity, and a tension sensor is installed on the flexible hose 47.

[0050] A second fixed plate 7 is fixedly connected to the fixed circular plate 492 by a connecting rod. A bracket structure 6 is provided on the second fixed plate 7. A solar panel 5 is installed on the bracket structure 6. A micro inverter is installed on the back of the solar panel 5. A lithium battery, an energy storage inverter, and a protection device are provided on the lower side of 492.

[0051] Working process: The first moving plate 1 is moved to the designated position manually. The position of the first moving plate 1 is fixed by the tire self-locking mechanism on the first moving plate 1. Then, the first drive motor 36 is started to drive the threaded rod 38 to rotate, which in turn drives the second moving plate 37 to move up and down. The movement of the second moving plate 37 drives the moving tube 32 to move up and down. The moving tube 32 moves upward along the inside of the fixed rod 31.

[0052] Open valve 43 and use flow control valve 46 to control the flow rate of gas in standard gas tank 42, and then deliver the gas to air detection sensor through hose 47. The gas discharges from the sealed cavity through one-way vent valve 495, and controls the air detection sensor to be calibrated. The control program is set with a periodic automatic calibration function, and the calibration cycle is determined according to the usage environment and frequency.

[0053] As the moving tube 32 moves upward, the servo motor 491 drives the wire feeding wheel 49 to rotate, causing the hose 47 to unfold and extend. As the chute 33 moves downward, the servo motor 491 rotates in the opposite direction, driving the wire feeding wheel 49 to rotate, thereby causing the wire feeding wheel 49 to wind up the hose 47. By adding a PID control algorithm, the speed of the servo motor 491 is adjusted in real time based on the feedback from the tension sensor to maintain a constant tension in the hose 47.

[0054] After the gas detection sensor detects the air quality, it closes valve 43, starts the second drive motor 494 to drive the second gear 4996 to rotate, and then drives the first gear ring 4995 to rotate. The rotation of the first gear ring 4995 drives the second fixed ring 499 to rotate. The rotation of the second fixed ring 499 causes the support rod 4991 to move along the arc groove, thereby causing the second extended connector 4994 to move outward. This causes the second extended connector 4994 to push the first extended connector 4993 to move, and causes the rotating arc plate 498 to deflect, thereby opening the sealing cavity. This allows the air detection sensor to detect air quality and transmit the information to the information receiving end using a wireless remote WIFI module.
