then after the air input is completed, the electromagnet 1302 works, the absorbing iron sheet 1304 presses the spring seat 1303 to approach one side of the electromagnet 1302 due to the attractive force, so that the absorbing iron sheet 1304 can drive the extension tube 1305 to move upwards to separate the extension tube 1305 from the detection compartment 18, at this time, the third motor 17 works to drive the rotating roller 16 to rotate, so that the second detection compartment 18 moves to the bottom end of the docking hole 15, after the electromagnet 1302 is powered off, the absorbing iron sheet 1304 moves downwards due to the loss of the attractive force, so that the extension tube 1305 extends into the inner side of the sealing valve 19 of the second detection compartment 18, at this time, the first air pump 3 continues to work, and the collecting bent tubes 701 at other heights can input the air into the second detection compartment 18 in cooperation with the opening and closing of the second electric control valve 6, so that the device can collect, sample and monitor four air samples at different heights at one time, in addition, two rotating rollers 16 are arranged, air can form a comparison group at the inner side of the monitoring box 14 through the flow division of the flow dividing pipe 12 and the blocking of the partition plate 20, the monitoring error can be greatly reduced through the comparison of the comparison group, and the monitoring precision of the equipment is further improved;
following the completion of the monitoring of the device, the second docking assembly 25 is operated, enabling the extension tube 1305 to be advanced inside the sealed valve 19, and the second suction pump 27 is operated to suck the air in the test compartment 18 inside the collecting main 26 and to discharge it through the exhaust duct 28, during the discharge of the air in the test compartment 18, the cleaning push plate 23 will slide on the inner side of the detection compartment 18 due to the suction force, the cleaning push plate 23 is made of rubber material, by the sliding cleaning of the cleaning push plate 23, fine dust and foreign substances adhering to the inner wall of the sensing compartment 18, which are difficult to be sucked, can be separated from the sensing compartment 18, and sucked by the extension pipe 1305, at the same time, the air in the detection compartment 18 can be completely exhausted, which can avoid the influence of excessive fine dust impurities on the light transmittance of the detection compartment 18, after the air suction is finished, the cleaning push plate 23 loses the suction force and can reset due to the pulling force of the reset spring 24;
then after outside air is sucked into the inner side of the air suction pipe 5, stronger air flow can be formed on the inner side of the air suction pipe 5, the stronger air flow can enable the rotating blades 802 to drive the transmission shaft 801 to rotate, the transmission shaft 801 can enable the copper plate 803 to rotate on the inner side of the rubber fixing sleeve 804 in the rotating process, and the copper plate 803 and the rubber fixing sleeve 804 are rubbed, negative charges can be generated in the rubbing process of the copper plate 803 and the rubber fixing sleeve 804, and the transmission shaft 801, the rotating blades 802 and the copper plate 803 are integrated, so that stronger static electricity can be generated on the surface of the rotating blades 802, and after the rotating blades 802 generate static electricity, fine dust impurities in air flowing through the air suction pipe 5 can be adsorbed, so that the dust impurities can be prevented from entering the inner side of the monitoring box 14 along with the air, and the influence on the monitoring result is caused;
finally, after the four collection bent pipes 701 collect air, the water conveying pipe 10 can input clean water to the water pump 9, the third electric control valve 11 is opened at the moment, the water pump 9 works, the clean water can be input into the air extraction pipe 5 and the inner sides of the collection bent pipes 701 and is discharged from the outlets of the collection bent pipes 701, and through washing of the clean water, residual air on the inner sides of the air extraction pipe 5 and dust adhered to the surfaces of the rotating blades 802 can be washed clean, so that the dust and the residual air are prevented from influencing subsequent air collection.
