Technical Field
[0001] The utility model relates to the technical field of natural gas detection, in particular to a real-time natural gas leakage alarm. Background Art
[0002] In the past, the detection of natural gas leakage mainly relied on manual inspections and olfactory judgments. However, this method is not only inefficient, but also difficult to ensure accuracy. Especially in some complex environments, such as underground pipelines and narrow spaces, manual inspections often cannot detect leakage points in a timely manner. In addition, the human sense of smell has limited sensitivity to natural gas, and it is difficult to detect trace leaks. Subsequently, some sensor-based detection devices emerged. In the prior art, in order to enable a natural gas leakage detection alarm to detect natural gas leakage in the first time, it is usually necessary to install it in the kitchen, close to the natural gas pipeline or gas stove. However, the kitchen has a large amount of fumes, and there is no device on the alarm to protect against fumes. After long-term use, it is easy to cause a large amount of grease to adhere to the alarm, affecting the detection port of the alarm. Therefore, we introduce a new real-time natural gas leakage alarm.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0029] A real-time natural gas leakage alarm includes a natural gas alarm main body 1. A groove 7 is opened in the middle of the lower end of the natural gas alarm main body 1.

[0030] The buzzer 3 and the plurality of indicator lights 2 are both electrically connected to the natural gas alarm main body 1 through wires.
[0031] In this embodiment, the auxiliary device 4 includes a bottom plate 42. Plug pins 41 are fixedly connected to the four corners of the upper end of the bottom plate 42. A filter screen 43 is fixedly connected to the middle of the lower end of the bottom plate 42.
