Description

Technical Field

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

[0002] Hazardous gas detectors are special safety and health detectors that are used to detect the content of flammable or toxic gases and vapors in the air in chemical workplaces or equipment and to alarm when they exceed the limit.

[0003] A Chinese patent with prior art authorization announcement number CN218036685U discloses a harmful gas detection device that is easy to install for environmental testing. By setting up an installation mechanism, the harmful gas detector can be installed quickly and conveniently through the cooperation of a magnetic mounting block, a magnetic mounting groove, a limiting inner groove, a magnetic anti-fool groove, a magnetic anti-fool block, and a limiting outer edge. When the harmful gas detector needs to be replaced, it is only necessary to remove the harmful gas detector without removing the mounting plate. This replaces the existing harmful gas detector fixed by bolts, which is convenient and quick.

[0004] Although the above patent can facilitate the installation and replacement of harmful gas detectors, it can only be used for harmful gas detectors of fixed size and cannot be installed and adjusted according to harmful gas detectors of different sizes. Moreover, it does not have an active air intake structure, resulting in air only passively entering the detector for detection, which reduces the detection efficiency and detection range of the detector.

[0005] Therefore, the applicant proposes a harmful gas detection device to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a harmful gas detection device.

The installation and adjustment can be performed according to harmful gas detectors of different sizes. The setting of the active air intake component allows the air to actively enter the harmful gas detector for detection, thereby improving the detection efficiency and detection range of the harmful gas detector.

[0020] 2. The utility model starts a small fan, and the suction force of the small fan will suck air into the air intake seat from the air intake hole, and remove dust through the filter. The air enters the sensor detection port for detection. When the harmful gas is detected to exceed the preset value, the alarm will be activated to send out an audible and visual alarm to remind the surrounding staff of the presence of harmful gas.

[0021] 3. The utility model improves the stability of the harmful gas detector by arranging a tightening component to tighten the mounting block, thereby preventing the harmful gas detector from moving along the slot direction due to external factors (such as accidental collision by staff, vibration caused by earthquake, etc.), causing errors in the detection of the detection position and resulting in inaccurate detection.
