When the resistance rod 8 moves vertically downward for a certain distance, it can separate from the resistance stop rod 10, so that the rotating frame 3 stops rotating, so that the position adjustment of the detection assembly 4 can be realized and detection can be performed. An opening 12 is provided in the mounting shell 1, and the transmission belt assembly 11 is arranged through the opening 12. The connecting shaft 13 and the output shaft of the reduction assembly 14 are fixedly connected, and the power motor assembly 15 can be connected to the corresponding supporting equipment to stably output power.

At the same time, the vertical plate member 7 can ensure the stable rotation of the horizontal axis 9 and the fan blade 6, so that the gas can move toward the horizontal end of the L-shaped channel 2 through the inclined end of the L-shaped channel 2.

[0033] Reference Figure 1-4 A fixed frame 5 is fixed on the top of the L-shaped channel 2, and a rotating frame 3 is rotatably sleeved on the fixed frame 5. A plurality of blocking rods 10 are evenly spaced at one end of the rotating frame 3 near the power mechanism. The plurality of blocking rods 10 are arranged in a circular shape, and the abutting rod 8 abuts against the blocking rod 10. Three detection components 4 are evenly spaced and installed on the rotating frame 3. The three detection components 4 are respectively a gas detection sensor, a temperature sensor, and a humidity sensor. In actual production and preparation, the prior art has disclosed how to perform gas detection through three detection components 4 and their supporting components, but the present application is in a train, and the compartment is in a closed state. The air inside the compartment is composed of fresh air outside the vehicle introduced by the engine and recycled air inside the compartment. The air in the compartment is made to flow through air conditioning, but the gas flow in the entire compartment cannot be fully guaranteed. The structure of the present application can achieve stable gas flow through corresponding components, so that the gas enters the L-shaped channel 2 for gas detection, and effectively realizes the detection of surrounding gas.

[0034] Reference Figure 1-4 A connecting ring 16 is detachably connected to the L-shaped channel 2, and a filter screen 20 is fixed inside the connecting ring 16. The filter screen 20 can effectively filter impurities and dust in the gas to achieve accurate detection of the gas.

A spring member 19 is sleeved on one end of the plug-in rod 18 located in the connecting ring 16. The two ends of the spring member 19 are respectively fixed to one end of the plug-in rod 18 located in the connecting ring 16 and the side wall in the connecting ring 16, so that the spring member 19 can push the plug-in rod 18 into the corresponding arc-shaped groove 17 to realize the detachable filter 20.

[0036] Reference Figure 1-4The opening and closing mechanism includes a bracket fixed at the top of the horizontal end of the L-shaped channel 2, a lead screw nut 26 is rotatably sleeved on the bracket, a lead screw 25 is threaded in the lead screw nut 26, a disc 27 is rotatably sleeved on the opposite end of the lead screw 25 and the rotating frame 3, and a resistance spring 28 is fixed on the opposite side of the two discs 27.

A horizontal plate frame is fixed in the middle of the collar 32, and a linkage rod 23 is slidably installed on the horizontal plate frame. The opposite ends of the linkage rod 23 and the lead screw 25 are rotatably connected to a synchronization rod 24, and both sides of the synchronization rod 24 are rotatably connected to diagonal rods 22. The lower ends of the two diagonal rods 22 are rotatably connected to cover plates 21, and the opposite ends of the two cover plates 21 are rotatably connected to the two sides of the cross plate frame respectively.

[0037] See also Figure 5 When the rotating frame 3 rotates, the fixed U-shaped rod 31 can drive the lead screw nut 26 to rotate, and the rotation of the lead screw nut 26 can make the lead screw 25 move stably to reduce the distance between the two discs 27. The lead screw 25 can pull the linkage rod 23 to move through the action of the synchronous rod 24, so that the cover plate 21 can be turned over through the inclined rod 22, so that the gas can enter the side of the cover plate 21 away from the filter 20, so that it is convenient for the detection component 4 to detect it. The resistance spring member 28 can restore the distance between the two discs 27 to the original position when there is no external force, so that the cover plate 21 and the collar member 32 can be pushed by the lead screw 25 to resist the seal. That is, when in use, a sealing structure can be formed between the cover member 21 and the ring member 32. When the fan blade 6 rotates, a low-pressure environment is formed in the space between the fan blade 6 and the cover member 21. When the cover member 21 is opened, the fan blade 6 can cooperate with the gas to quickly enter the inclined port of the L-shaped channel 2 and flow along the L-shaped channel 2, making it easier for the detection component 4 to detect the air condition.

[0038] In the present utility model, the power motor assembly 15 can be connected to the corresponding supporting equipment to output power stably, and at the same time, the connecting shaft 13 can drive the transmission belt assembly 11 to rotate, provide power for the rotation of the horizontal axis 9, and enable the interference rod 8 to perform a circular motion. The rising interference rod 8 will interfere with a corresponding blocking rod 10, which can push the rotating frame 3 to drive the detection assembly 4 to rotate. When the interference rod 8 moves vertically downward for a certain distance, it can separate from the blocking rod 10 that it interferes with, so that the rotating frame 3 stops rotating, so that the position adjustment of the detection assembly 4 can be achieved and detection can be performed. The horizontal axis 9 can drive the fan blades 6 to rotate, and at the same time, the vertical plate 7 can ensure the stable rotation of the horizontal axis 9 and the fan blades 6, so that the gas can pass through the inclined end of the L-shaped channel 2 to move toward the horizontal end of the L-shaped channel 2 for detection.
