The mechanical principle and the process for replacing the sensitive element are as follows:

1. when the detector of the fluorescence spectrometer senses that the service life of the sensitive element is exhausted, the detector informs a controller (namely a main control and driving board); 2. the controller controls the first motor to rotate to drive the screw rod to rotate, so that the screw rod nut, the lifting plate, the spline shaft, the turntable and the sensitive component are driven to ascend along the guide rod, the purpose is to separate the sensitive component from the storage box, and the sensitive component with the exhausted service life is separated from the fluorescence spectrometer, so that the gas circuit is disconnected; in the lifting process, the guide rods on two sides and the linear bearings enable the movement to be smooth. The inner ring of the linear bearing is sleeved at the top of the spline shaft, and the outer ring of the linear bearing is connected with the guide rod. Remarking: the sensitive component needs to be sealed by a gas circuit, so that a sealing ring structure is arranged in the gas circuit, and the sealing ring is an O-shaped sealing ring. The lower end of the sensitive component is separated from the sealing ring in the ascending process, and the gas circuit is disconnected; after descending, the sensitive component is inserted into the sealing ring again, the air path is closed, the number of the sealing rings at the upper end of the sensitive assembly is large, the number of the sealing rings at the lower end of the sensitive assembly is small, and the sensitive component can move along with the structure at the upper end and can be separated from the structural component at the lower end due to friction. 3. When the first motor rotates to the position, the first motor feeds back to the controller, and the controller controls the second motor to rotate by a preset angle, so that the next sensitive component rotates to a position right above the fluorescence spectrometer. The principle is as follows: the second motor rotates to drive the driving belt wheel to rotate, and the synchronous belt drives the driven belt wheel to rotate, so that the rotary hollow shaft, the spline sleeve, the spline shaft, the turntable connecting piece, the turntable and the sensitive assembly are driven to rotate. Wherein, the rotary hollow shaft 50 is sleeved on the outer side of the spline housing 35, and the driven pulley 34 is sleeved on the outer side of the rotary hollow shaft 50. Remarking: the coded disc can be a light-cutting coded disc, and the sensor can be an initial position sensor, the light-cutting coded disc and the initial position sensor provide an initial position resetting function. 4. After the turntable rotates to a designated position, the servo motor encoder feeds back the controller, the controller controls the first motor to rotate to drive the lead screw to rotate, so that the lead screw nut, the lifting plate, the spline shaft, the turntable and the sensitive assembly are driven to descend along the guide rod, the purpose is to insert the sensitive assembly with the exhausted service life into the storage box and insert the next new sensitive assembly into the fluorescence spectrometer, and the gas path is closed; 5. when the sensitive component is inserted into the storage box, the servo motor encoder informs the controller, and the controller controls the air pump to work, so that air suction is performed, and gas detection is performed through the fluorescence spectrometer.
