Description

Technical Field

[0001] The present invention relates to the technical field of chemical agent detection, in particular to a portable chemical agent detection device. Background Art

[0002] Classification of toxic agents: Toxic agents are divided into nerve agents (sarin), blister agents (mustard gas), systemic toxic agents (hydrocyanic acid), incapacitating agents (bitz), asphyxiating agents (phosgene), etc. according to their toxic effects.

The detection result of the detection rod is transmitted to a display screen for display so that an operator can observe the detection result. After the detected chemical agent is poured in, a cleaning liquid is added into the interior of the detection frame. At this time, the motor is started to start the operation. The motor drives the right-angle plate to rotate through the rotating rod.

The surface of the linkage plate contacts the inner wall of the sliding hole, and the linkage plate is used to limit the lifting frame, thereby improving the stability of the scraper during the cleaning operation.

[0017] The right-angle plate of the present invention drives the stirring plate to rotate through the telescopic rod when rotating, and pushes the cleaning liquid to rotate inside the detection frame through the stirring plate, so that the cleaning liquid has a certain impact force inside the detection frame, and can quickly flush out the residual chemical agent on the inner wall of the detection frame. The stirring plate is squeezed by the pressure of the cleaning liquid to squeeze the elastic sheet to produce deformation, and the elastic sheet pushes the limit frame to move toward the end away from the bracket. During the movement, the squeezing plate is pulled to squeeze the arc plate, further improving the fitting strength between the inclined brush plate and the detection rod. The stirring plate located below squeezes the arc plate to move downward, and the arc plate is used to squeeze the elastic frame, thereby improving the detection strength between the scraper and the bottom of the inner wall of the detection frame.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
