Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically a multi-parameter gas detection alarm. Background Technology

[0002] In the current field of gas detection, the demand for multi-parameter gas detection alarms is becoming increasingly urgent. Traditional single-parameter or few-parameter gas detection alarms can no longer meet the needs of simultaneous and accurate detection of multiple gases in complex environments. In terms of gas collection, some existing gas detection alarms often suffer from low collection efficiency and cannot effectively overcome the adverse effects of environmental factors such as airflow turbulence, dust, and impurities on gas collection, resulting in insufficient gas sample volume and difficulty in ensuring the accuracy of subsequent precise detection. In terms of installation, most traditional gas detection alarms are cumbersome to install, either because they are not securely installed and are prone to loosening, or because they have poor adaptability to different usage scenarios and cannot be quickly installed and removed, failing to meet the need for flexible use in different environments and scenarios.

[0003] The applicant discovered a Chinese patent, "A Multi-Parameter Gas Detection Alarm," with publication number CN221079399U. This patent primarily consists of an alarm body, detection probes, and a fixing and connecting assembly. The alarm body has a display screen on its front, an alarm sound on one side of the screen, a warning light on its top, a connecting sleeve on one side, and a connecting plug on the side of the sleeve closest to the alarm body. The bottom of the alarm body has multiple probe interfaces, with a connecting wire connected to the end of each probe interface furthest from the alarm body. The detection probe is connected to the end of the connecting wire furthest from the probe interface. The connecting assembly is located at the rear of the alarm body. This assembly facilitates disassembly and installation of the gas detection alarm. The multiple probe interfaces allow for the detection of various gases, and the device for fixing the probes allows adjustment of the probe height based on the gas density. However, this device does not improve gas collection efficiency. Therefore, we propose a multi-parameter gas detection alarm. Utility Model Content

[0029] Working principle:

[0030] First, the motor 32 starts running under the drive of the power supply. The motor 32 is located in the middle of the bracket 31, which is fixed to the inner end of the air inlet pipe 3. The rotating shaft of the motor 32 is connected to the fixed frame 33, transmitting power to the fixed frame 33. The fixed frame 33 is connected to the bottom of the rotating frame 34, thereby driving the rotating frame 34 to rotate. Four sets of air inlets 35 are evenly distributed around the rotating frame 34. During the rotation of the rotating frame 34, the surrounding gas is drawn in through the air inlets 35. The guide plate 36 on one side of the air inlet 35 guides the airflow to enter the air inlet 35 more smoothly, improving the gas collection efficiency and avoiding airflow turbulence. The sealing ring 37 at the end of the air inlet pipe 3 effectively seals the gap between the air inlet pipe 3 and the rotating frame 34, preventing gas leakage and ensuring that the gas can enter the device completely. The gas enters the main body 1 through the air inlet pipe 3. A row of connection ports is located on the lower side of the main body 1. 6. The gas is received and then undergoes a series of detection processes in the main body 1. If an abnormality is detected in the gas, such as the concentration of harmful gas exceeding the set threshold, the two sets of alarm sounds 9 on the front of the main body 1 will sound immediately, and the display screen 8 will display relevant alarm information to alert the staff that a dangerous situation has occurred. During installation, the mounting bracket 43 is installed on the wall surface, the slide groove 4 below the main body 1 is aligned with the slider 41 on the load-bearing frame 42 and pushed in, and then the limit rod 46 is pulled. Using the elastic force of the spring 45 at the bottom of the limit rod 46 in a stretched state, the limit rod 46 is locked in the limit groove 47 to ensure that the main body 1 will not detach from the load-bearing frame 42, thus achieving quick installation and removal. The mounting blocks 48 on both sides of the main body 1 can also be used to directly install the device on the wall surface with screws, providing a variety of installation methods to adapt to different usage scenarios and needs. At this point, the entire workflow is completed.
