The movable shaft 503 is fixedly mounted on the surfaces of the left and right sides of the detection box 1 and is movably connected to the carrying handle 501.

[0024] The above scheme is adopted: through the setting of the voice announcer 302, the status, alarm information or operation instructions of the detector are conveyed to the user through sound prompts, so that the user can understand the working status of the equipment in time and improve the warning effect. Through the setting of the signal warning light 303, it is used to send out a warning signal when a danger occurs or exceeds the set threshold.

At the same time, the voice announcer 302 will broadcast the concentration value in real time. Once the safety detection range is exceeded, the alarm light will send a warning signal. Different colors of lights represent different states, such as red for danger, yellow for warning, and green for normal.

[0029] To sum up: the electric telescopic rod 201, cleaning plate 202 and electrostatic brush 203 contained in the cleaning mechanism 2 can enable the device to have the function of using the electrostatic brush 203 during use. The electrostatic brush 203 is made of electrostatic fine hair and is used to absorb and remove electrostatic dust on the surface of the detector 9. The electrostatic brush 203 can effectively absorb and remove tiny particles attached to the surface of the device by contacting and moving with the surface, thereby improving its accuracy and stability and extending the service life of the detector 9. The alarm 301, voice announcer 302 and signal warning light 303 contained in the alarm mechanism 3 can enable the device to have timely sound and visual warning functions during use, effectively reminding the user that the detected methane gas concentration exceeds the set safety threshold, thereby ensuring the safety of the staff.
