Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a device for odor detection. Background Art

[0002] Industrial production, municipal sewage, sludge treatment and garbage disposal facilities are the main sources of malodorous gases. The odor detection device is a device used to conduct real-time detection of various malodorous gases generated in garbage treatment plants, sewage treatment plants and other fields. It monitors the main body of odor emission in real time, quickly understands the law of odor emission, and ensures the timeliness of monitoring data, so as to effectively prevent odor emission indicators from exceeding the standard and causing pollution to the surrounding environment. In actual application, multiple detection equipment needs to be set according to the environment to ensure the accuracy of the test results; using multiple detection equipment for detection at the same time can certainly ensure the accuracy of the results, but the overall cost investment is relatively high, so a small number of equipment is often used to replace the detection points to obtain sufficient test data. However, when existing detection equipment is installed, it is mostly fixed with screws and bolts. The fixing method is relatively traditional and not easy to replace, which brings inconvenience to use. Utility Model Content

[0023] Working principle: In actual use, multiple fixed back plates 2 can be fixed on the installation plane according to the use situation, and the detection box 1 can be set on different fixed back plates 2 according to the use needs.

[0024] The structure of the fixed back plate 2 is relatively simple, which effectively reduces its cost investment compared with the detection box 1. The detection box 1 is clamped in the upper fixing member 3 and the lower fixing member 4 through the mounting groove 17 on the back, and the upper limit pin 31 and the lower limit pin 41 are correspondingly clamped with the limit holes 18 on the upper and lower sides to achieve clamping.
