[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This atmospheric pollutant detection and early warning device is provided with a stirring mechanism, etc. When it is necessary to detect atmospheric pollutants, air is first inflated into the first fixed cover through the inflation mechanism, so that the airbag is inflated and abuts against the inner wall of the detection tube to form a sealing effect. Then, the moving module drives the moving column to move away from the detection tube. At the same time, the solenoid valve is opened to generate negative pressure in the detection tube. At this time, the atmosphere can enter the spiral tube through the air intake pipe and the fixed box. Under the action of the spiral tube, the atmosphere can be mixed to make it more uniform. Then, it enters the detection tube through the solenoid valve. At the same time, when the atmosphere enters the air intake pipe, it will enter the fixed box and impact the surface of the baffle, so that the baffle and the third rotating rod rotate. When the third rotating rod rotates, it can drive the first synchronous pulley to rotate. At the same time, the gear belt drives the two second rotating rods to rotate, and then drives the blade and the second rotating ring to rotate, so that the atmosphere entering the detection tube can be stirred to make it more uniform, thereby improving the accuracy of the detection result of the detection sensor.

[0016] (2) This type of atmospheric pollutant detection and early warning device, by setting up a first driving mechanism, etc., can drive the first push pin to slide in the first spiral groove through the L-shaped plate when the movable column moves during detection, thereby driving the spiral plate to rotate, and then driving the first rotating ring and the detection sensor to rotate, so that the detection sensor can automatically rotate during the detection process, which can make the detection result more accurate.

[0017] (3) This type of atmospheric pollutant detection and early warning device, by setting up a second driving mechanism, etc., during detection, when the moving column moves in the direction away from the detection cylinder, it can drive the push plate to move synchronously through the first connecting plate. At this time, the third push pin can slide upward along the inclined groove. At the same time, the moving block is driven upward by the second connecting plate, thereby driving the second push pin to slide upward along the second spiral groove, and then driving the first rotating rod and the detection cylinder to rotate. When the detection cylinder rotates, it can drive the intake pipe to rotate synchronously, thereby facilitating the inhalation detection of the atmosphere at different angles, and making the detection result more accurate.

[0018] (4) This atmospheric pollutant detection and early warning device is provided with a sealing mechanism, etc. When air extraction detection is required, the electromagnet is energized, and the electromagnet attracts the iron block after being energized, so that the second connecting block moves downward along the T-shaped guide rod, and the second movable plate moves downward along the second fixed cover. At the same time, the elastic member is compressed. At this time, the air temporarily stored in the second fixed cover can be squeezed and enter the first fixed cover through the hose, so that the air bag and the inner wall of the detection tube are against each other to form a sealing effect. After the detection is completed, the solenoid valve is closed and the electromagnet is de-energized. At this time, the second connecting block is compressed. The second movable plate can move upward and reset under the action of the elastic member, so that it can absorb the air in the first fixed cover, causing the airbag to shrink and reset, and allowing the air in the first fixed cover to enter the second fixed cover through the hose for temporary storage. At this time, the atmosphere in the detection cylinder can be discharged through the gap between the detection cylinder and the movable column. Then, the movable column is driven to move and reset through the movable module. When the end of the movable column contacts the end of the detection cylinder, air is filled into the first fixed cover again through the inflation mechanism, so that the airbag is inflated and abuts against the inner wall of the detection cylinder to ensure normal detection next time.

When the third rotating rod 402 rotates, it can drive the first synchronous pulley 404 to rotate. At the same time, the two second rotating rods 301 are driven to rotate through the gear belt 406, thereby driving the blades 305 and the second rotating ring 303 to rotate.

[0047] See also Figure 6 , the second driving mechanism comprises: The second spiral groove 501 is formed on the side wall of the first rotating rod 25 .

[0048] The guide mechanism is disposed below the detection tube 16 , and the moving block 502 is connected to the guide mechanism. The guide mechanism is used to guide the movement of the moving block 502 .

[0049] The second pushing pin 503 is inserted into the second spiral groove 501 and fixed to the side wall of the moving block 502 .

[0050] The pushing mechanism is arranged below the moving column 17, and is used for pushing the moving block 502 to move up and down. When performing detection, when the moving column 17 moves in the direction away from the detection cylinder 16, the moving block 502 is pushed upward by the pushing mechanism, thereby driving the second pushing pin 503 to slide upward along the second spiral groove 501, and then driving the first rotating rod 25 and the detection cylinder 16 to rotate. When the detection cylinder 16 rotates, it can drive the air intake pipe 21 to rotate synchronously, thereby facilitating the inhalation detection of the atmosphere at different angles, and can make the detection result more accurate.

[0051] See also Figure 6 , the guiding institutions include: Two guide rods 702 are fixed on the top of the moving block 502 .

[0052] The two guide tubes 701 are sleeved on the side walls of the two guide rods 702 , and the upper ends of the guide tubes 701 are fixed to the lower part of the detection cylinder 16 , so as to guide and limit the movement of the moving block 502 .

[0055] See also Figure 8 and Fig. 9 , the sealing mechanism includes: The first fixed cover 801 is arranged in an annular shape and is fixedly sleeved on the side wall of the moving column 17 , and one end of the first fixed cover 801 close to the solenoid valve 19 is flush with the end of the moving column 17 .

[0056] The annular air bag 802 is fixedly inserted in the first fixed cover 801 .

[0057] The inflation mechanism is arranged above the movable column 17 and is used to inflate the airbag 802. When vacuum testing is required, air is inflated into the first fixed cover 801 through the inflation mechanism, so that the airbag 802 abuts against the inner wall of the detection tube 16 to form a sealing effect. After the test is completed, the airbag 802 can be contracted and reset. At this time, the atmosphere in the detection tube 16 can be discharged through the gap between the detection tube 16 and the movable column 17.

[0058] See also Figure 4 , Figure 7 and Figure 8 , the inflation mechanism includes: The second fixed cover 902 is fixed to the end of the moving column 17 through the L-shaped block 901 and is connected to the first fixed cover 801 through the hose 904 .

[0059] The second movable plate 903 is inserted into the second fixed cover 902 .

[0060] The lifting mechanism is arranged on the side wall of the second fixed cover 902, and is used to lift and move the second movable plate 903. When inflating, the lifting mechanism is used to move the second movable plate 903 downward along the second fixed cover 902, so that the air temporarily stored in the second fixed cover 902 can be squeezed and enter the first fixed cover 801 through the hose 904, so that the airbag 802 is abutted against the inner wall of the detection tube 16 to form a sealing effect. After the detection is completed, the lifting mechanism is used to move the second movable plate 903 upward and reset, so that the air in the first fixed cover 801 can be absorbed, so that the airbag 802 shrinks and resets, and the air in the first fixed cover 801 enters the second fixed cover 902 through the hose 904 for temporary storage.

[0061] See also Figure 7 , the lifting mechanism includes: The two T-shaped guide rods 1002 are fixed to the side wall of the second fixed cover 902 through the first connecting block 1001 .

[0062] The second connecting block 1003 is sleeved on the side walls of the two T-shaped guide rods 1002 and fixed to the side walls of the second movable plate 903 .

[0063] Two elastic members 1004 are sleeved on the side walls of the two T-shaped guide rods 1002 , and the elastic members 1004 are located between the first connecting block 1001 and the second connecting block 1003 . The elastic members 1004 can be springs, and both ends of the elastic members 1004 are fixed to the first connecting block 1001 and the second connecting block 1003 .

[0064] The electromagnet 1006 is fixed on the top of the first connecting block 1001 .

[0065] The iron block 1005 is fixed to the bottom of the second connecting block 1003 and is arranged opposite to the electromagnet 1006. When the electromagnet 1006 is energized, the electromagnet 1006 attracts the iron block 1005, so that the second connecting block 1003 moves downward along the T-shaped guide rod 1002, and the second movable plate 903 moves downward along the second fixed cover 902. At the same time, the elastic member 1004 is compressed.

[0066] Working principle: When in use, the movable base 1 is moved to the position to be detected, and the height is adjusted by the lifting module 15. When it is necessary to detect atmospheric pollutants, the electromagnet 1006 is energized. After the electromagnet 1006 is energized, it attracts the iron block 1005, so that the second connecting block 1003 moves downward along the T-shaped guide rod 1002, and the second movable plate 903 moves downward along the second fixed cover 902. At the same time, the elastic member 1004 is compressed. At this time, the air temporarily stored in the second fixed cover 902 can be squeezed and enter the first fixed cover 801 through the hose 904, so that the airbag 802 is against the inner wall of the detection tube 16 to form a sealing effect.

[0067] Next, the moving column 17 is driven by the moving module 18 to move in the direction away from the detection cylinder 16. At the same time, the solenoid valve 19 is opened to generate negative pressure in the detection cylinder 16. At this time, the atmosphere can enter the spiral tube 20 through the air inlet pipe 21 and the fixed box 401. Under the action of the spiral tube 20, the atmosphere can be mixed to make it more uniform. Then, the atmosphere enters the detection cylinder 16 through the solenoid valve 19. At the same time, when the atmosphere enters the air inlet pipe 21, it will enter the fixed box 401 and impact the surface of the baffle 403, so that the baffle 403 and the third rotating rod 402 rotate. When the third rotating rod 402 rotates, it can drive the first synchronous pulley 404 to rotate. At the same time, the two second rotating rods 301 are driven to rotate through the gear belt 406, and then the blades 305 and the second rotating ring 303 are driven to rotate, so that the atmosphere entering the detection cylinder 16 can be stirred to make it more uniform, thereby improving the accuracy of the detection result of the detection sensor 13.

[0068] During detection, when the movable column 17 moves, the first push pin 204 can be driven to slide in the first spiral groove 202 through the L-shaped plate 203, thereby driving the spiral plate 201 to rotate, and then driving the first rotating ring 23 and the detection sensor 13 to rotate, so that during the detection process, the detection sensor 13 can rotate automatically, which can make the detection result more accurate.

[0069] During detection, when the movable column 17 moves in the direction away from the detection cylinder 16, the push plate 601 can be driven to move synchronously through the first connecting plate 602. At this time, the third push pin 604 can slide upward along the inclined groove 603. At the same time, the movable block 502 is driven to move upward through the second connecting plate 605, thereby driving the second push pin 503 to slide upward along the second spiral groove 501, and then driving the first rotating rod 25 and the detection cylinder 16 to rotate. When the detection cylinder 16 rotates, it can drive the air intake pipe 21 to rotate synchronously, thereby facilitating the inhalation detection of the atmosphere at different angles, and can make the detection result more accurate. When the detection sensor 13 detects that the gas in the device is contaminated, an early warning is given through the alarm light 12.

[0070] After the detection is completed, the solenoid valve 19 is closed, and the electromagnet 1006 is powered off. At this time, the second movable plate 903 can move upward and reset under the action of the elastic member 1004, so that the air in the first fixed cover 801 can be absorbed, so that the airbag 802 shrinks and resets, and the air in the first fixed cover 801 enters the second fixed cover 902 through the hose 904 for temporary storage. At this time, the atmosphere in the detection cylinder 16 can be discharged through the gap between the detection cylinder 16 and the movable column 17. Then, the movable column 17 is driven to move and reset through the movable module 18. When the end of the movable column 17 contacts the end of the detection cylinder 16, air is filled into the first fixed cover 801 again through the inflation mechanism, so that the airbag 802 expands and abuts against the inner wall of the detection cylinder 16 to ensure normal detection next time.
