The industrial gas enters the air inlet pipe 9, and is analyzed by the inspection body 1 and discharged through the air outlet pipe 10 to achieve detection. At the same time, the industrial gas detection results are transmitted through the signal transmitter 8 to the device control mechanism. When harmful gas is found, the device control mechanism activates the alarm horn 12 to warn people in the range of the poisonous gas to escape in time.

[0030] In some embodiments, see Figure 3The fixing mechanism includes a first support plate 3, which is installed on the upper surface of the support platform 2. A support member 4 is fixedly connected to one side of the upper surface of the first support plate 3, a handle 5 is rotatably connected to one side of the inner surface of the support member 4, a connecting rod 6 is rotatably connected to one side of the outer surface of the handle 5, a support ring 16 is fixedly connected to one side of the upper surface of the support member 4, a clamping rod 7 is slidably connected to one side of the inner surface of the support ring 16, one end of the clamping rod 7 is rotatably connected to the connecting rod 6, and the output end of the clamping rod 7 matches the fixing port of the reserved part; four fixing mechanisms are provided, and the four fixing mechanisms are respectively provided at the four corners of the upper surface of the support platform 2.

The output end of the clamping rod 7 is interlaced with the fixed port of the reserved part to achieve the effect of fixing the position of the detection device. When it is necessary to remove and replace the inspection device, turn the handle 5 counterclockwise to rotate the connecting rod 6 and shrink in the opposite direction, so that the clamping rod 7 shrinks through the support ring 16 to achieve the purpose of disassembly. The industrial gas enters the air inlet pipe 9, is analyzed by the inspection body 1, and is discharged through the air outlet pipe 10 to achieve detection. At the same time, the industrial gas detection result is transmitted to the detection body 1 through the signal transmitter 8. If harmful gas is found, the alarm horn 12 is activated to warn people in the range of the poisonous gas to escape in time. At the same time, the alarm light 15 is activated to achieve the warning effect, so as to complete the detection of industrial gas in urban traffic construction.
