The pushing plate 6204 and the second slider 6206 are connected in a fixed manner. A second guide groove 6208 is arranged inside the lower part of the pushing plate 510, and a second guide rod 6209 is arranged on the inner side of the second guide groove 6208. The second guide rod 6209 and the pushing plate 6204 are connected in a fixed manner. An elastic telescopic rod 6210 is fixedly connected to the lower inner side of the pushing plate 6204, and an annular grinding plate 6211 is fixedly connected to the inner side of the elastic telescopic rod 6210. The appearance structure of the second guide groove 6208 is a spiral shape, and the second guide groove 6208 and the second guide rod 6209 are matched in a clearance match, so that the second guide rod 6209 will gradually move inward or outward when rotating on the inner side of the second guide groove 6208, and a spring 6212 is fixedly connected to the top of the first slider 6201.

[0035] When the gas enters the interior of the housing 1, it is necessary to accelerate the contact between the gas and the denitration catalyst 511. The specific operation is as follows:

[0036] The starting motor 501 drives the rotating shaft 502 to rotate, thereby causing the first rotating rod 503 and the first push rod 504 to rotate. Since the first push rod 504 is nested inside the second guide hole 509, and the second guide hole 509 is inside the fixed plate 507, the appearance structure of the second guide hole 509 is a horizontal straight line, and the second guide hole 509 and the first push rod 504 are matched in a clearance fit, so that when the first push rod 504 pushes the inside of the second guide hole 509, it can drive the fixed plate 507 and the second push rod 506 to move up and down, thereby driving the push plate 510 moves up and down, so that the push plate 510 pushes the gas turned from the upper end downward evenly. Because the appearance structure of the first guide hole 508 is an arc shape, and the first guide hole 508 and the first push rod 504 are matched in a clearance fit, when the first push rod 504 moves on the inner side of the first guide hole 508, it will not drive the push plate 510 to move up and down, so that the push plate 510 is kept at the bottom for a period of time, so that the gas can contact the denitration catalyst 511 more fully. Because the gas is pushed to contact the denitration catalyst 511, the detection efficiency is improved.

[0037] When the push plate 510 moves downward, the third push rod 6101 is driven to move downward. When the third push rod 6101 moves downward, it contacts the top of the denitration catalyst 511, and the third push rod 6101 moves upward. Because the appearance structure of the first guide groove 6104 is spiral, and the first guide groove 6104 and the first guide rod 6105 are matched in a clearance fit, the third push rod 6101 rotates during the upward movement. During the rotation of the third push rod 6101, the first slider 6201 is driven to rotate, so that the connecting plate 6202 and the third hole 6203 rotate. The push plate 6204 arranged on the inner side of the third hole 6203 and the second guide rod 6209 fixedly connected to the push plate 6204 rotate. Since the appearance structure of the second guide groove 6208 is vortex-shaped, and the second guide groove 6208 and the second guide rod 6209 are matched in a clearance fit, the second guide rod 6209 moves toward the center during the rotation, driving the elastic telescopic rod 6210 and the annular grinding plate 6211 to move toward the center, rotate and move downward, thereby cleaning the outer side of the denitration catalyst 511, reducing blockage, allowing the gas to more fully contact the denitration catalyst 511, and improving the detection efficiency.

[0038] When the push plate 510 drives the gas to move downward, the outer side of the denitration catalyst 511 is cleaned. This is because the denitration catalyst 511 absorbs more when the push plate 510 drives the gas to move downward. Cleaning the outer side of the denitration catalyst 511 at this time can more fully absorb the gas, reduce the waste of the denitration catalyst 511, and improve the accuracy of the experiment.
