[0004] In the above patent, multi-directional monitoring of the concentration of particulate matter in the surrounding air can be carried out, thereby improving the monitoring efficiency. At the same time, the user can easily and conveniently disassemble the monitoring device body, improving the installation efficiency of the monitoring device body. However, when detecting particulate matter in the air, the detection accuracy will be affected due to the limited detection range, and the detection part cannot be adjusted during the detection work. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic particulate matter monitoring device and a monitoring method thereof, which solve the problems mentioned in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An automatic particulate matter monitoring device includes a detection device and an intake device. The intake device is arranged on the top of the detection device. A gas inlet pipe is rotatably installed on the top of the intake device, and a control device is arranged on the surface of the gas inlet pipe. Among them, the control device includes a connecting gear, a driving device, a transmission gear, a support frame, an arc-shaped block, a push rod, an annular sleeve, an air inlet, an inclined block, and a sealing cover. The connecting gear is fixedly installed on the circumferential surface of the intake pipe. The driving device is slidably installed on the top of the intake device. The transmission gear is fixedly installed on the circumferential surface of the output end of the driving device. The transmission gear meshes with the connecting gear. The support frame is fixedly installed at the bottom of the outer wall of the intake pipe. The arc-shaped block is fixedly installed on the top of the intake device. The push rod slidably penetrates through the support frame. The annular sleeve is slidably installed inside the intake pipe. The air inlet is fixedly installed on the top of the intake pipe. The inclined block is fixedly installed on the left side of the annular sleeve. The sealing cover is fixedly installed on the top of the intake device. There are two air inlets on the top of the intake pipe. When the push rod rotates, it will contact the arc-shaped block, and the reaction force of the arc-shaped block will push the push rod upward. When the push rod moves upward, it will contact the inclined surface of the inclined block.

[0007] According to the above technical solution, a first spring is provided between the annular sleeve and the intake pipe. The push rod slidably penetrates through the inner and outer walls of the intake pipe so that the push rod can contact the inclined block when moving upward. The bottom of the push rod contacts the top of the arc-shaped block. The top of the push rod contacts the inclined block. A support spring is provided between the push rod and the support frame so that the arc-shaped block will push the push rod to move when the push rod rotates.

[0008] According to the above technical solution, a protection device for protecting the intake pipe from being impacted is provided on the circumferential surface of the intake pipe, and a support device for preventing the detection device from tipping over is provided on the surface of the intake device. The protection device includes a protective cover, an elastic telescopic rod, an annular plate, a connecting block, an inclined panel, a cross plate, an annular block, a pressing rod, and a spherical block. The protective cover is fixedly installed on the circumferential surface of the intake pipe through a first elastic piece. The elastic telescopic rod is fixedly installed on the left side of the protective cover. The annular plate is slidably installed on the circumferential surface of the intake pipe. The free end of the elastic telescopic rod is slidably connected to the right side of the annular plate. The connecting block is fixedly installed on the left side of the fixed end of the elastic telescopic rod. The inclined panel is fixedly installed on the right side of the annular plate. The cross plate is sleeved on the circumferential surface of the intake pipe. The annular block is fixedly installed on the top of the cross plate. The pressing rod is fixedly installed on the bottom of the cross plate. The spherical block is fixedly installed on the top of the output end of the driving device. The protective cover will protect the intake pipe. The reaction force of the obstacle will push the protective cover towards the intake pipe. When the protective cover moves, it will drive the elastic telescopic rod to move.

[0009] According to the above technical solution, a fixed rod is fixedly installed on the left side of the driving device, an inclined surface disk is fixedly installed on the circumferential surface of the fixed rod, and an elastic telescopic block is fixedly installed at the bottom of the inner wall of the sealing cover. The elastic telescopic block will limit the inclined surface disk and the driving device from resetting to the right, thereby preventing the connecting gear from meshing with the transmission gear again, resulting in the driving device continuing to drive the air inlet pipe to rotate.

[0010] According to the above technical solution, the free end at the bottom of the elastic telescopic block is set as an inclined surface, and the inclined surface is located on the right side of the bottom of the elastic telescopic block. The elastic telescopic block will unidirectionally block the inclined surface disk through the inclined surface at the bottom on the right side of the elastic telescopic block. The bottom of the extrusion rod contacts the spherical block. A second spring is arranged between the inclined surface disk and the sealing cover, and the annular plate contacts the annular block.

[0011] According to the above technical solution, the supporting device includes a flat plate, a transmission plate, a transmission rod, a circular cylinder, a moving plate, a connecting rod, a supporting plate, a clamping block and a clamping rod. The flat plate is fixedly installed on the circumferential surface of the air inlet device. The transmission plate is fixedly installed on the top of the flat plate through a second elastic piece. The transmission rod is fixedly installed on the top of the transmission plate. The circular cylinder is fixedly installed on the bottom of the flat plate. The moving plate is slidably installed inside the circular cylinder. The connecting rod is fixedly installed on the right side of the moving plate. The supporting plate is fixedly installed at one end of the connecting rod away from the moving plate. The clamping block is fixedly installed on the left side of the moving plate. The clamping rod is fixedly installed at the bottom of the transmission plate. The inclined surface of the inclined surface disk will contact the transmission rod, so that when the inclined surface disk moves to the left, it will push the transmission rod downward, and when the transmission rod moves downward, it will drive the transmission plate downward.

[0012] According to the above technical solution, a third spring is arranged between the moving plate and the circular cylinder, and the elastic force of the third spring will drive the moving plate to move. The clamping rod slidably penetrates through the flat plate, and the transmission rod slidably penetrates through the air inlet device, so that the air inlet device will support the transmission rod.

[0013] According to the above technical solution, the clamping block contacts the clamping rod, the top of the transmission rod contacts the inclined surface disk, and three groups of circular cylinders are arranged at the bottom of the flat plate, so that the supporting plate can protect the detection device when the detection device is tilted in any direction.

[0014] A monitoring method for a particulate matter automatic monitoring device, using the above particulate matter automatic monitoring device, includes the following steps: Step 1: When it is necessary to detect particulate matter in the air, the air inlet device intakes air into the interior of the detection device through the air inlet pipe and the air inlet. Step 2: Start the driving device. When the driving device works, it will drive the transmission gear to rotate. When the transmission gear rotates, it will drive the connecting gear and the air inlet pipe to rotate. Step 3: When the intake pipe rotates, it will drive the support frame to rotate. When the support frame rotates, it will drive the push rod to rotate. When the push rod rotates, it will contact the arc-shaped block. Step 4: The arc-shaped block will push the push rod to move upward. The push rod will push the inclined plane block and the annular sleeve to move, so as to adjust the intake position of the air inlet.

[0015] The present invention provides a particulate matter automatic monitoring device and its monitoring method. It has the following beneficial effects: (1) In this invention, the driving device and the transmission gear will drive the intake pipe to rotate. By rotating the intake pipe, the detection range can be increased, making the detection of particulate matter more accurate. When the intake pipe rotates, it will drive the support frame and the push rod to rotate. When the push rod contacts the arc-shaped block, the push rod will push the inclined plane block and the arc-shaped sleeve to move. The annular sleeve will intermittently block the air inlet, so as to change the intake position of the air inlet, and thus the detection position can be adjusted, making the detection of particulate matter more accurate.

[0016] (2) In this invention, when the intake pipe rotates, it will drive the protective cover to rotate. The protective cover can protect the end of the intake pipe. When the protective cover collides with an obstacle, the protective cover will move towards the intake pipe, so that the connecting block on the elastic telescopic rod will push the inclined panel and the annular plate to move. When the annular plate moves, the extrusion rod will push the driving device to move away from the connecting gear, and the connecting gear will disengage from the transmission gear, making the transmission gear unable to continue driving the intake pipe to rotate, avoiding the intake pipe from continuing to hit the obstacle. At the same time, the elastic telescopic block can prevent the inclined disk and the driving device from resetting.

[0017] (3) In this invention, when the inclined disk moves, it will push the transmission rod to move downward. When the transmission rod moves downward, it will drive the transmission plate to move downward. When the transmission plate moves downward, the clamping rod will release the limit on the clamping block. The moving plate and the connecting rod will drive the support plate to move. When the support plate opens, it will protect the surrounding of the detection device, avoiding damage to the detection device caused by the intake pipe hitting an object and causing the detection device to fall to the ground. The support plate can play a buffering role when the detection device hits the ground, preventing the detection device from directly hitting the ground. Description of the Drawings

[0022] A first spring is arranged between the annular sleeve 10 and the intake pipe 3. The push rod 9 slidably penetrates through the inner and outer walls of the intake pipe 3, so that the push rod 9 can contact the inclined block 12 when moving upward. The bottom of the push rod 9 contacts the top of the arc-shaped block 8. The top of the push rod 9 contacts the inclined block 12. A support spring is arranged between the push rod 9 and the support frame 7. The support spring will support the push rod 9 inside the left support frame 7, so that the arc-shaped block 8 will push the push rod 9 to move when the push rod 9 rotates.

[0023] A monitoring method for a particulate matter automatic monitoring device, using the above-mentioned particulate matter automatic monitoring device, includes the following steps: Step 1: When it is necessary to detect particulate matter in the air, the intake device 2 intakes air into the interior of the detection device 1 through the intake pipe 3 and the air inlet 11; Step 2: Start the driving device 5. When the driving device 5 works, it will drive the transmission gear 6 to rotate.

[0024] During the operation of the present embodiment: When it is necessary to detect particulate matter in the air, the intake device 2 intakes air into the interior of the detection device 1 through the intake pipe 3 and the air inlet 11. The detection device 1 will detect the particulate matter in the air. When the intake pipe 3 intakes air, the driving device 5 is started. When the driving device 5 operates, it will drive the transmission gear 6 to rotate. When the transmission gear 6 rotates, it will drive the connecting gear 4 and the intake pipe 3 to rotate. When the intake pipe 3 rotates, it will drive the support frame 7 to rotate. When the support frame 7 rotates, it will drive the push rod 9 to rotate. When the push rod 9 rotates, it will contact the arc-shaped block 8. The reaction force of the arc-shaped block 8 will push the push rod 9 to move upward. When the push rod 9 moves upward, it will contact the inclined surface of the inclined surface block 12, so that when the push rod 9 moves upward, it will push the inclined surface block 12 and the annular sleeve 10 to move. When the annular sleeve 10 moves, it will intermittently block the two air inlets 11, so that the intake position of the intake pipe 3 can be switched, and thus the particulate matter at different positions in the air can be detected.

[0025] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, a protection device for protecting the intake pipe 3 from being impacted is provided on the circumferential surface of the intake pipe 3, and a support device for preventing the detection device 1 from tipping over is provided on the surface of the intake device 2. The protection device includes a protective cover 141, an elastic telescopic rod 142, an annular plate 143, a connecting block 144, an inclined panel 145, a horizontal plate 146, an annular block 147, a pressing rod 148 and a spherical block 1412. The protective cover 141 is fixedly installed on the circumferential surface of the intake pipe 3 through a first elastic piece. The elastic telescopic rod 142 is fixedly installed on the left side of the protective cover 141. The annular plate 143 is slidably installed on the circumferential surface of the intake pipe 3. The free end of the elastic telescopic rod 142 is slidably connected to the right side of the annular plate 143. The connecting block 144 is fixedly installed on the left side of the fixed end of the elastic telescopic rod 142. The inclined panel 145 is fixedly installed on the right side of the annular plate 143. The horizontal plate 146 is sleeved on the circumferential surface of the intake pipe 3. The annular block 147 is fixedly installed on the top of the horizontal plate 146. The pressing rod 148 is fixedly installed on the bottom of the horizontal plate 146. The spherical block 1412 is fixedly installed on the top of the output end of the driving device 5. The connecting gear 4 will disengage from the transmission gear 6, so that the transmission gear 6 cannot continue to drive the intake pipe 3 to rotate, avoiding the intake pipe 3 from continuing to impact obstacles.

[0026] A fixing rod 149 is fixedly installed on the left side of the driving device 5. An inclined surface disk 1410 is fixedly installed on the circumferential surface of the fixing rod 149. An elastic telescopic block 1411 is fixedly installed on the bottom of the inner wall of the sealing cover 13. The elastic telescopic block 1411 will limit the inclined surface disk 1410 and the driving device 5 from resetting to the right, so as to prevent the connecting gear 4 from re-engaging with the transmission gear 6, resulting in the driving device 5 continuing to drive the intake pipe 3 to rotate.

[0027] The bottom free end of the elastic telescopic block 1411 is set as an inclined plane, and the inclined plane is located on the right side of the bottom of the elastic telescopic block 1411. Through the inclined plane on the right side of the bottom of the elastic telescopic block 1411, the elastic telescopic block 1411 will perform one-way blocking on the inclined plane disk 1410. The bottom of the extrusion rod 148 contacts the spherical block 1412. A second spring is arranged between the inclined plane disk 1410 and the sealing cover 13, and the annular plate 143 contacts the annular block 147.

[0028] The support device includes a flat plate 151, a transmission plate 152, a transmission rod 153, a circular cylinder 154, a moving plate 155, a connecting rod 156, a support plate 157, a clamping block 158 and a clamping rod 159. The flat plate 151 is fixedly installed on the circumferential surface of the air inlet device 2. The transmission plate 152 is fixedly installed on the top of the flat plate 151 through a second elastic piece. The transmission rod 153 is fixedly installed on the top of the transmission plate 152. The circular cylinder 154 is fixedly installed on the bottom of the flat plate 151.

The support plate 157 is fixedly installed at one end of the connecting rod 156 away from the moving plate 155. The clamping block 158 is fixedly installed on the left side of the moving plate 155. The clamping rod 159 is fixedly installed on the bottom of the transmission plate 152, so that the support plate 157 can play a buffering effect when the detection device 1 hits the opposite surface, preventing the detection device 1 from directly hitting the opposite surface.

[0029] A third spring is arranged between the moving plate 155 and the circular cylinder 154. The elastic force of the third spring will drive the moving plate 155 to move. The clamping rod 159 slidably penetrates through the flat plate 151, and the transmission rod 153 slidably penetrates through the air inlet device 2, so that the air inlet device 2 will support the transmission rod 153.

[0030] The clamping block 158 contacts the clamping rod 159. The top of the transmission rod 153 contacts the inclined plane disk 1410. Three groups of circular cylinders 154 are arranged at the bottom of the flat plate 151, so that the support plate 157 can protect the detection device 1 no matter in which direction the detection device 1 topples.

[0031] During the operation of this embodiment: When the intake pipe 3 rotates, it will drive the protective cover 141 to rotate. When the intake pipe 3 rotates and contacts an obstacle, the protective cover 141 will contact the obstacle, and the protective cover 141 will protect the intake pipe 3. The reverse force of the obstacle will push the protective cover 141 towards the intake pipe 3. When the protective cover 141 moves, it will drive the elastic telescopic rod 142 to move. When the elastic telescopic rod 142 moves, it will drive the connecting block 144 to move. When the connecting block 144 moves, it will contact the inclined surface of the inclined panel 145, so that when the connecting block 144 moves, it will push the inclined panel 145 to move to the left. When the inclined panel 145 moves to the left, it will contact the arc surface of the annular block 147, so that when the inclined panel 145 moves to the left, it will push the annular block 147 and the cross plate 146 to move downward. When the cross plate 146 moves downward, it will drive the extrusion rod 148 to move downward. When the extrusion rod 148 moves downward, it will contact the spherical block 1412, and when the extrusion rod 148 moves downward, it will push the spherical block 1412 and the driving device 5 to move to the left. When the driving device 5 moves to the right, it will drive the transmission gear 6 to disengage from the connecting gear 4, so that the rotation of the transmission gear 6 will not drive the connecting gear 4 and the intake pipe 3 to rotate. When the driving device 5 moves to the left, it will drive the fixing rod 149 to move to the left. When the fixing rod 149 moves to the left, it will drive the inclined surface plate 1410 to move to the left. When the inclined surface plate 1410 moves to the left, the inclined surface of the inclined surface plate 1410 will contact the bottom of the elastic telescopic block 1411. When the inclined surface plate 1410 moves to the left, it will push the free end of the elastic telescopic block 1411 to contract upward. When the inclined surface plate 1410 moves to the left of the elastic telescopic block 1411, the self-elastic force of the elastic telescopic block 1411 will push the free end of the elastic telescopic block 1411 to move downward, so that the elastic telescopic block 1411 will block the fixing rod 149, the inclined surface plate 1410 and the driving device 5 from moving to the right, and push the fixing rod 149 into the interior of the sealing cover 13. The movement of the fixing rod 149 will push the driving device 5 and the inclined surface plate 1410 to move to the right. When the inclined surface plate 1410 moves to the right, it will contact the left inclined surface of the elastic telescopic block 1411, so that when the inclined surface plate 1410 moves to the right, it will push the elastic telescopic block 1411 to contract upward. After the inclined surface plate 1410 moves to the right of the elastic telescopic block 1411, the free end of the elastic telescopic block 1411 will move downward under the action of its own elastic force. The downward movement thrust of the elastic telescopic block 1411 will limit the inclined surface plate 1410 to the right of the elastic telescopic block 1411. When the driving device 5 moves, it will drive the transmission gear 6 to re-engage with the connecting gear 4; When the inclined surface disk 1410 moves to the left, the inclined surface of the inclined surface disk 1410 will contact the transmission rod 153. When the inclined surface disk 1410 moves to the left, it will push the transmission rod 153 downward. When the transmission rod 153 moves downward, it will drive the transmission plate 152 downward. When the transmission plate 152 moves downward, it will drive the clamping rod 159 downward. When the clamping rod 159 moves downward, it will disengage from the clamping block 158, so that when the clamping rod 159 moves downward, the limit on the clamping block 158 will be released. Under the elastic force of the third spring, the third spring will drive the moving plate 155 to move to the right. When the moving plate 155 moves, it will drive the connecting rod 156 to move to the outside of the circular cylinder 154. When the connecting rod 156 moves, it will drive the support plate 157 to move. The movement of the support plate 157 will increase the protection range of the detection device 1 and prevent the detection device 1 from falling directly onto the ground. The support plate 157 will support the detection device 1. Pushing the support plate 157 to move in the direction of the circular cylinder 154, the support plate 157 will drive the connecting rod 156 to move into the circular cylinder 154. When the connecting rod 156 moves, it will drive the moving plate 155 and the clamping block 158 to move in the direction of the clamping rod 159. When the clamping block 158 moves, the inclined surface of the clamping block 158 will contact the inclined surface of the clamping rod 159, so that when the clamping block 158 moves, it will push the clamping rod 159 downward. When the moving plate 155 and the clamping block 158 move, the clamping block 158 will re-engage into the inside of the clamping rod 159, and the clamping rod 159 will continue to limit the clamping block 158 and the moving plate 155.
