In this embodiment, the combination of the gas monitoring device 2 and the gas processing device 3 is set as one or two groups. When one group is set, it moves on the circular track 1 at a constant speed. When two groups are set, they move on the circular track 1 at a constant speed. In this embodiment, two groups are set; the gas exhaust device 4 is installed on the roof of the laboratory and is located in the area surrounded by the circular track 1. In this embodiment, more than two groups of gas exhaust devices 4 are set, corresponding to at least one group in the main culture area of ​​the biological laboratory. The distance between multiple gas exhaust devices 4 and the circular track 1 is the same.

The sensor assembly 22 is electrically connected to the controller 23. The sensor assembly 23 is used to sense the concentration of harmful gases in the moving area. If the concentration exceeds the maximum concentration allowed in the laboratory (i.e., the maximum allowable concentration threshold set by the sensor), the sensor assembly 22 sends a sensing signal. The controller 23 receives and processes the sensing signal, and then sends a control command to the drive motor of the mobile body 21 and the gas processing device 3. The drive motor stops rotating, and the gas processing device 3 processes the harmful gas.

[0029] The gas processing device 3 includes an exhaust bin 31, an exhaust fan 32, an air intake hopper 33, an air outlet pipe 34 and a lifting and adjusting part. An exhaust passage is arranged inside the exhaust bin 31, and the exhaust bin 31 is connected to the outer wall of the protective shell 24 on the side facing the inner circle of the circular track 1; the exhaust fan 32 is installed in the exhaust bin 31 and blows air upward to exhaust. In this embodiment, the exhaust fan 32 is electrically connected to the controller 23 and is used to execute the control command issued by the controller 23. When the gas processing device 3 needs to be exhausted, the exhaust fan 32 is started; the air intake hopper 33 is arranged in a funnel shape with a larger opening on the lower side, and the upper end is arranged in the lower part of the exhaust bin 31 and is connected to the inside of the exhaust bin 31; the air outlet pipe 34 is connected to the top of the exhaust bin 31, and the air outlet pipe 34 is arranged as a retractable structure with the opening facing upward. In this embodiment, the air outlet pipe 34 is arranged as a retractable bellows, and the upper end can be connected to the gas exhaust device 4. The lifting and lowering adjustment part is connected between the upper end of the air outlet pipe 34 and the exhaust chamber 31, and the lifting and lowering adjustment part includes a lower support 35, an upper support 36 and a distance control part 37; the lower support 35 is sleeved on the outside of the air outlet pipe 34 and fixed on the top surface of the exhaust chamber 31, the upper support 36 is opposite to the lower support 35 up and down, and is sleeved and fixed on the upper end of the air outlet pipe 34, the distance control part 37 is set as an electric cylinder, the upper end of which is fixedly connected to the upper support 36 and the lower end is fixed to the lower support 35, the distance control part 37 is used to control the distance between the lower support 35 and the upper support 36, and then control the length of the air outlet pipe 34, the distance control part 37 is electrically connected to the controller 23, and is used to receive and execute the control command of the controller 23.

[0030] The upper support 36 is a rectangular structure, and guide strips 38 are arranged on the outer sides of the two side edges parallel to the moving direction of the mobile body 21. A hanging ring 39 is connected to the upper surface of the rear side edge of the upper support 36 perpendicular to the moving direction of the mobile body 21. The hanging ring 39 is set as a rectangular ring and arranged perpendicular to the upper surface of the upper support 36.

[0031] The gas exhaust device 4 includes an exhaust pipe 41, a connecting seat 42, a hook 43 and a one-way valve. The lower end of the exhaust pipe 41 is connected to the laboratory and is perpendicular to the laboratory roof plane, and the upper end of the exhaust pipe 41 is connected to the outside of the laboratory. The one-way valve is connected to the exhaust pipe 41 so that the exhaust pipe 41 can only discharge air to the outside of the laboratory. The connecting seat 42 is connected to the lower end of the exhaust pipe 41. The connecting seat 42 is also set as a rectangular frame structure. The lower sides of the two sides parallel to the moving direction of the mobile body 21 are connected with L-shaped support bars. The space between the two support bars can be used for the upper support 36 to slide and insert. The upper support 36 is stuck on the two support bars on the connecting seat 42 through the guide bar 38. A hook 43 in the form of a rectangular block is set on the exhaust pipe 41 on the side facing the mobile body 21. The height of the hook 43 is higher than the height of the connecting seat 42. When the upper support 36 is inserted into the mounting seat 42, the hanging ring 39 is set on the hook 43 to prevent the mobile body 21 from sliding forward.

[0032] The implementation principle of the embodiment of the present application is as follows: the gas monitoring device 2 and the gas processing device 3 move at a constant speed of 0.1 m / s along the circular track 1 under the control of the controller 23; when the concentration of harmful gases in a certain area in the laboratory exceeds the standard, the corresponding sensor in the sensor assembly 22 senses the excessive concentration and sends a sensing signal to the controller 23. The controller 23 receives and processes the sensing signal, and then sends a control command to the drive motor of the mobile body 21. The mobile body 21 gradually stops. At the same time, the controller 23 controls the distance control member 37 to rise and the exhaust fan 32 to rotate. After the upper support 36 rises to the maximum height, it will gradually move and be inserted into the connecting seat 42. The hanging ring 39 is hung on the hook 42 to prevent the mobile body 21 from continuing to move. At this time, the outlet pipe 34 is connected to the exhaust pipe 41, and the exhaust fan 32 rotates to extract the air within the range of harmful gases exceeding the standard through the air inlet hopper 33 and transport it to the outside of the laboratory.
