[0016] Step 2: Start the drive motor, and the output end of the drive motor drives the winding roller to rotate counterclockwise through the belt. The winding roller reels the filter paper tape during rotation, so that the filter paper tape moves toward the winding roller;

[0017] Step 3: The movement of the filter paper belt drives the unwinding roller to rotate clockwise, and at the same time, the movement of the filter paper belt drives the rotating roller to rotate. After the filter paper belt moves to the designated position, the monitoring mechanism is started;

[0019] The present invention provides an automatic monitoring device for atmospheric particulate matter, which has the following beneficial effects:

[0020] (1) In the automatic atmospheric particulate matter monitoring device, the elastic sheet exerts a reaction force on the rubber block, so that the rubber block is in close contact with the card slot. By arranging the rubber block on the limit plate, the closeness of the contact between the limit plate and the card slot can be effectively improved, thereby enhancing the stability of the limit plate during use. At the same time, the movement of the filter paper belt drives the particulate matter to move toward the monitoring mechanism. By changing the contact position between the air and the filter paper belt through standardized operation, the sampling of atmospheric particulate matter is ensured to be more uniform, and the error caused by improper height is reduced, thereby improving the accuracy of particulate matter detection.

[0021] (2) In the automatic atmospheric particulate matter monitoring device, the movement of the sliding rod drives the contact plate to move upward, and the movement of the contact plate applies an upward thrust to the L-shaped plate. The upward thrust applied by the contact plate to the L-shaped plate reduces the physical strength required by the operator in adjusting the position of the rectangular plate, thereby improving the overall work efficiency. At the same time, the telescopic rod contacts the limit groove, so that the telescopic rod applies a limit to the hollow block. The telescopic rod automatically applies a limit to the hollow block, which simplifies the operation steps. In addition, a spherical surface is provided to reduce the friction between the telescopic rod and the hollow column, thereby improving the service life of the telescopic rod.

[0022] (3) In the automatic atmospheric particulate matter monitoring device, friction is generated between the L-shaped plate and the rubber plate. The moving speed of the L-shaped plate is slowed down by the influence of friction. The intermittent friction between the rubber plate and the L-shaped plate is achieved through the intermittent contact between the hollow block and the multiple short blocks, and the L-shaped plate is effectively controlled to move downward smoothly, thereby ensuring the safety of the operating environment. At the same time, the knocking piece collides with the C-shaped block to generate vibration during the rapid recovery process. The intermittent contact between the hollow block and the multiple short blocks is achieved, and the intermittent collision between the knocking piece and the C-shaped block generates continuous vibration, which helps to improve the smoothness of the overall movement.

[0039] A monitoring method of an automatic atmospheric particulate matter monitoring device, using the above-mentioned automatic atmospheric particulate matter monitoring device, comprises the following steps:

[0040] Step 1: The air flows through the first through slot and the second through slot into the interior of the hollow column 3, and the air contacts the surface of the filter paper belt 10, and the particles in the air adhere to the surface of the filter paper belt 10;

[0041] Step 2: Start the drive motor 6. The output end of the drive motor 6 drives the winding roller 8 to rotate counterclockwise through the belt. The winding roller 8 winds up the filter paper belt 10 during the rotation, so that the filter paper belt 10 moves toward the winding roller 8.

[0042] Step 3: The filter paper belt 10 moves to drive the unwinding roller 7 to rotate clockwise, and at the same time, the filter paper belt 10 moves to drive the rotating roller 9 to rotate. After the filter paper belt 10 moves to the designated position, the monitoring mechanism 2 is started;

[0043] Step 4: The detection module of the monitoring mechanism 2 detects the particles attached to the surface of the filter paper belt 10, and feeds back the detection results to the operator through the display module. The operator records the detection results to complete the monitoring work.

[0044] When the present embodiment is working, the air flows into the interior of the hollow column 3 through the No. 1 through slot and the No. 2 through slot, the air contacts the surface of the filter paper belt 10, and the particles in the air adhere to the surface of the filter paper belt 10. The drive motor 6 is started, and the output end of the drive motor 6 drives the winding roller 8 to rotate counterclockwise through the belt. The winding roller 8 winds up the filter paper belt 10 during the rotation, so that the filter paper belt 10 moves toward the winding roller 8. The movement of the filter paper belt 10 drives the unwinding roller 7 to rotate clockwise. At the same time, the movement of the filter paper belt 10 drives the rotating roller 9 to rotate. The movement of the filter paper belt 10 drives the particles to move toward the monitoring mechanism 2. When the filter paper belt 10 moves to the specified position, the monitoring mechanism 2 is started, and the detection module of the monitoring mechanism 2 detects the particles attached to the surface of the filter paper belt 10. The detection is carried out and the detection result is fed back to the operator through the display module. When the monitoring height needs to be adjusted, the grip rod 13 is held and moved in the direction away from the lifting tube 12. The grip rod 13 stretches the No. 1 spring 14 during the movement. The No. 1 spring 14 is deformed by the stretching. At the same time, the grip rod 13 moves and drives the limit plate 15 to move in the direction away from the mounting frame 11. The limit plate 15 is separated from the card slot during the movement, so that the limit imposed by the limit plate 15 on the lifting tube 12 is released, and the grip rod 13 is pushed to move upward. The movement of the grip rod 13 drives the limit plate 15 to move upward. At the same time, the movement of the grip rod 13 drives the lifting tube 12 to move upward. The movement of the lifting tube 12 drives the L-shaped plate 16 to move upward. The movement of the L-shaped plate 16 drives the rectangular plate 17 to move upward. The rectangular plate 17 moves upward. The position of the No. 2 through-slot is changed in the middle. When the rectangular plate 17 moves to the predetermined position, the grip 13 is controlled to move in the direction of the lifting tube 12. The grip 13 moves and drives the limit plate 15 to move in the direction of the mounting frame 11. The limit plate 15 contacts the inner wall of the slot during movement, so that the limit plate 15 applies a limit to the lifting tube 12. The contact position between the air and the filter paper belt 10 is changed through standardized operation to ensure more uniform sampling of atmospheric particulate matter, reduce errors caused by improper height, and thus improve the accuracy of particulate matter detection. When the limit plate 15 moves in the direction away from the mounting frame 11, the limit plate 15 moves and drives the rubber block 18 to move in the direction away from the mounting frame 11. The No. 1 corrugated groove of the rubber block 18 generates friction with the slot during movement. When the No. 1 corrugated groove is moved, the rubber block 18 moves in the direction away from the mounting frame 1 ... When the contact surface between the groove and the card slot is separated, the deformed elastic sheet 19 recovers and drives the rubber block 18 to move toward the grip 13. When the limit plate 15 moves toward the mounting frame 11, the limit plate 15 moves and drives the rubber block 18 to move toward the mounting frame 11. The No. 1 corrugated groove of the rubber block 18 contacts the card slot during movement. The card slot applies resistance to the moving rubber block 18. The rubber block 18 moves toward the elastic sheet 19 under the influence of the resistance. The rubber block 18 squeezes the elastic sheet 19 during movement. The elastic sheet 19 is squeezed and deformed. The deformed elastic sheet 19 applies a reaction force to the rubber block 18, so that the rubber block 18 is in close contact with the card slot. By arranging the rubber block 18 on the limit plate 15, the tightness of the contact between the limit plate 15 and the card slot can be effectively improved.Thereby, the stability of the limiting plate 15 during use is enhanced.

[0050] When the present embodiment is working, the support frame 209 provides support for the L-shaped plate 16 through the convex groove, so that the L-shaped plate 16 moves more smoothly.

The telescopic rod 206 separates from the limiting groove during the movement, so that the limiting position imposed by the telescopic rod 206 on the hollow block 205 is released. The second spring 203 is restored to its original state and drives the sliding rod 202 to move upward. The sliding rod 202 moves and drives the hollow block 205 to move upward. The hollow block 205 moves and drives the telescopic rod 206 to move upward. The telescopic rod 206 moves and drives the pulling plate 207 to move upward. At the same time, the sliding rod 202 moves and drives the contact plate 204 to move upward. The contact plate 204 moves and applies an upward thrust to the L-shaped plate 16. The upward thrust applied to the L-shaped plate 16 by the contact plate 204 reduces the physical strength required by the operator in adjusting the position of the rectangular plate 17, thereby improving the overall work efficiency. When the gripping rod 13 is pushed downward, the L-shaped plate 16 applies downward pressure to the groove, so that the L-shaped plate 16 moves to drive the contact plate 204 to move downward, and the contact plate 204 moves to drive the sliding rod 202 to move downward. The sliding rod 202 squeezes the second spring 203 during the movement, and the second spring 203 is squeezed and deformed. At the same time, the sliding rod 202 moves to drive the hollow block 205 to move downward, and the hollow block 205 moves to drive the telescopic rod 206 to move downward. The spherical surface of the telescopic rod 206 generates friction with the surface of the hollow column 3 during the movement. At the same time, the telescopic rod 206 moves to drive the pull rod 206 to move downward. The movable plate 207 moves downward, and when the spherical surface 1 separates from the surface of the hollow column 3, the deformed No. 3 spring 208 recovers and drives the pulling plate 207 to move in the direction of the hollow column 3. The pulling plate 207 moves and drives the telescopic rod 206 to move in the direction of the hollow column 3. The telescopic rod 206 contacts the inner wall of the limit groove during the movement, so that the telescopic rod 206 applies a limit to the hollow block 205. The telescopic rod 206 automatically applies a limit to the hollow block 205, which simplifies the operation steps, and provides the spherical surface 1 to reduce the friction between the telescopic rod 206 and the hollow column 3, thereby increasing the service life of the telescopic rod 206.

[0051] When the hollow block 205 moves downward, the arc surface 1 of the hollow block 205 contacts the arc surface 2 of the short block 214, and the arc surface 1 moves to squeeze the arc surface 2. The short block 214 is squeezed and moves in the direction of the No. 4 spring 213. The movement of the short block 214 drives the sliding plate 212 to move in the direction of the No. 4 spring 213. The sliding plate 212 squeezes the No. 4 spring 213 during the movement. The No. 4 spring 213 is squeezed and deformed. At the same time, the movement of the sliding plate 212 drives the rubber plate 215 to move in the direction of the No. 4 spring 213. The No. 2 corrugated groove of the rubber plate 215 contacts the L-shaped plate 1 during the movement. 6, so that the L-shaped plate 16 moves and generates friction with the rubber plate 215. The speed of the L-shaped plate 16 moving downward is slowed down by the friction force. When the arc surface 1 separates from the arc surface 2, the deformed spring 213 restores and drives the sliding plate 212 to move away from the fixed frame 211. The sliding plate 212 moves and drives the rubber plate 215 to reset. The second corrugated groove separates from the L-shaped plate 16 during movement. At the same time, the sliding plate 212 moves and drives the short block 214 to reset. When the hollow block 205 continues to move and contacts the second short block 214, the rubber plate 2 The above movement is repeated to slow down the speed of the L-shaped plate 16 moving downward. The hollow block 205 and the plurality of short blocks 214 are intermittently in contact, so that the rubber plate 215 and the L-shaped plate 16 are intermittently rubbed, and the L-shaped plate 16 is effectively controlled to move downward smoothly, thereby ensuring the safety of the operating environment. When the sliding plate 212 moves in the direction of the fourth spring 213, the sliding plate 212 moves and drives the striking piece 216 to move in the direction of the C-shaped block 217. The arc surface 3 of the striking piece 216 contacts the arc surface 4 of the C-shaped block 217 during the movement. The arc surface 4 applies resistance to the arc surface 3, and the arc surface 3 is blocked. The knocking piece 216 affected by the force continues to move and bends. When the arc surface three is separated from the arc surface four, the deformed knocking piece 216 quickly recovers under the action of automatic elasticity. During the rapid recovery process, the knocking piece 216 collides with the C-shaped block 217 to generate vibration. The C-shaped block 217 transmits the vibration to the sliding plate 212. The sliding plate 212 moves more smoothly due to the influence of the vibration. Through the intermittent contact between the hollow block 205 and the multiple short blocks 214, the intermittent collision between the knocking piece 216 and the C-shaped block 217 generates continuous vibration, which helps to improve the smoothness of the overall movement.
