A plurality of air inlet groups are uniformly arranged on the outer wall of the collection ring 11, and each air inlet group is composed of a plurality of collection holes 13 for inhaling air. A lead screw 26 is rotatably connected in the monitoring box 3, one end of the lead screw 26 is connected to the output shaft of a motor through a coupling, and the motor is fixed on the outer wall of the monitoring box 3 through bolts.

[0052] With reference to Figure 2 and Figure 4 The driving structure is arranged on the top of the upper cover plate 7 and used for driving the self-rotation of the collection ring 11. The driving structure comprises a rotating shaft 17 which is rotatably arranged on the top of the upper cover plate 7 through the base. A first bevel gear 18 is fixed on one end of the rotating shaft 17 close to the installation column 1. A nut 15 is rotatably connected to the top of the upper cover plate 7, and a threaded segment is arranged on the outer wall of the installation column 1 and threadedly connected with the nut 15. A second bevel gear ring 16 is fixed on the outer wall of the nut 15 and engaged with the first bevel gear 18. A second bevel gear 19 is fixedly sleeved on the outer wall of the rotating shaft 17. A first bevel gear ring 14 is fixedly sleeved on the outer wall of the collection ring 11 and engaged with the bottom side of the second bevel gear 19, and the bottom side of the second bevel gear 19 extends to the lower side of the upper cover plate 7.

[0053] With reference to Figure 2 The top of the upper cover plate 7 is further fixed with a driving motor 20 through the rack. The output shaft of the driving motor 20 is fixedly connected with one end of the rotating shaft 17 through a shaft coupling. In this way, when the driving motor 20 is started, it can synchronously drive the nut 15 and the collection ring 11 to rotate.

[0054] Specifically, the driving motor 20 drives the second bevel gear 19 and the first bevel gear 18 to rotate. The first bevel gear 18 drives the nut 15 to rotate through the second bevel gear ring 16, and the nut 15 is matched with the threaded section of the mounting column 1, thereby driving the upper cover plate 7, the lower cover plate 8 and the collection ring 11 to lift as a whole. At the same time, the second bevel gear 19 drives the collection ring 11 to rotate through the matching with the first bevel gear ring 14. Therefore, the collection ring 11 rotates while lifting. In this way, when collecting gas, the collection ring 11 can collect gas at different orientations and heights through the collection holes 13 thereon.

[0055] With reference to Figure 2 , Figure 4 and Figure 6 , the gas outlet structure comprises a second fixed ring 35 fixed on the top of the lower cover plate 8, and the second fixed ring 35 is rotatably sleeved on the outer wall of the collection ring 11. The outer wall of the second fixed ring 35 is rotatably connected with a circular ring sleeve 36, and a guide pipe 39 is fixedly penetrated in the circular ring sleeve 36. One end of the guide pipe 39 is fixedly extended into a rotating plate 38, and the rotating plate 38 is provided with a plurality of conical holes 40 near the side close to the annular steel wire mesh 10. The conical holes 40 are used to blow the gas injected from the second fixed ring 35 to the annular steel wire mesh 10. The conical holes 40 are designed to have a smaller inner diameter on the side close to the annular steel wire mesh 10 than on the side away from the annular steel wire mesh 10, so as to increase the flow rate of the gas.

[0056] With reference to Figure 4 , the side of the rotating plate 38 away from the conical holes 40 is fixedly provided with a plurality of fixed rods 37, and the fixed rods 37 are fixedly connected with the outer wall of the collection ring 11. Therefore, when the collection ring 11 rotates, it will drive the rotating plate 38 to rotate synchronously through the fixed rods 37.

[0057] With reference to Figure 1 and Figure 9 , the top of the monitoring box 3 is fixedly provided with an exhaust box 33, and the top of the exhaust box 33 is fixedly provided with an exhaust hose 34. The top end of the exhaust hose 34 is fixedly extended into the second fixed ring 35, and is used to discharge the monitored gas in the monitoring box 3 into the second fixed ring 35. Both ends of the exhaust box 33 are fixedly penetrated with a second connecting hose 31, and the mutually close ends of the two second connecting hoses 31 are respectively fixedly communicated with the two sides of the monitoring box 3.

[0058] During the movement of the moving plate 25 left and right, it can not only inject gas, but also be used for exhaust. The outer walls of the two second connecting hoses 31 are respectively provided with an electromagnetic valve 32, which is used to control the flow of the gas.

[0059] Specifically, the mobile plate 25 discharges the gas into the exhaust tank 33 through the second connecting hose 31, and then the gas is discharged into the second fixed ring 35 through the exhaust tank 33 and the exhaust hose 34. After that, the gas is injected into the rotating plate 38 through the conduit 39. The collection ring 11 drives the rotating plate 38 to rotate synchronously through the fixed rod 37, and the gas is blown to the annular steel wire filter screen 10 through the conical hole 40. Due to the design characteristics of the conical hole 40, the flow rate of the gas discharged from the conical hole 40 increases, which can blow away the lint and fine sand attached to the annular steel wire filter screen 10.

[0060] In addition, the air inlet group and the rotating plate 38 are arranged in a staggered manner. Therefore, when the conical hole 40 blows air, it does not affect the collection of gas by the collection hole 13. In this way, the entire device can realize efficient and accurate gas collection and filter screen cleaning functions.

[0061] Referring to Figure 2 and Figure 4 The top of the upper cover plate 7 is fixedly provided with a protective shell 21. The main function of the protective shell 21 is to protect the internal driving structure from the influence or damage of the external environment. The top end of the mounting column 1 is designed to penetrate the protective shell 21 to ensure that the overall structure of the device is stable and the function is not affected.

[0062] Referring to Figure 2 and Figure 4 On one side of the top of the upper cover plate 7, a warning light 22 is also fixedly installed. The function of the warning light 22 is to issue a warning signal when it is detected that the particulate matter pollution in the atmospheric environment exceeds the preset threshold, reminding relevant personnel to take timely response measures.

[0063] Referring to Figure 1 One side of the monitoring box 3 is fixedly provided with a closure plate 4 in a detachable manner. The design of the closure plate 4 facilitates the removal of the closure plate 4 in the later stage, so as to clean and maintain the inside of the monitoring box 3, and ensure the accuracy of the monitoring data and the long-term stable operation of the device.

[0064] Referring to Figure 7 and Figure 9 The two ends of the sliding rod 29 are fixedly provided with rubber pads 30. The main function of the two rubber pads 30 is to close the two adjacent first connecting hoses 24 respectively when the sliding rod 29 moves to a specific position, so as to prevent air or particulate matter from flowing in unnecessary channels and affecting the accuracy of the monitoring results.

[0065] Example 2: Referring to Figure 10 and Figure 11On the basis of embodiment 1, it is improved: in addition, the two sides of the monitoring box 3 are fixed with circular shafts 45 through the base, and the outer wall of the circular shaft 45 is rotatably sleeved with a placing plate 42. The design of the placing plate 42 is to attract birds to stay and promote the harmonious coexistence of urban and natural environment. The top of the placing plate 42 is provided with a plurality of feed inclined grooves 43, and each feed inclined groove 43 is fixed with a baffle 44. When the placing plate 42 is in a vertical state, these baffles 44 can prevent the feed from flowing out of the feed inclined groove 43.

[0066] Reference Figure 10 The two sides of the moving plate 25 are fixed with push rods 41, which cooperate with the placing plate 42 to control the conversion of the placing plate 42 from a vertical state to a horizontal state. The two sides of the monitoring box 3 are provided with holes matched with the push rods 41, so that the push rods 41 can extend to one side of the monitoring box 3 and push the placing plate 42 to rotate.

[0067] Reference Figure 11 The bottom side of the placing plate 42 is fixed with a plurality of magnet blocks 46, and the two sides of the monitoring box 3 are fixed with iron layers. When the placing plate 42 is in a vertical state, the magnetic attraction force between the magnet blocks 46 and the iron layers makes the placing plate 42 tightly adhere to one side of the monitoring box 3 and close the hole, preventing air leakage in the monitoring box 3.

[0068] In actual operation, when the moving plate 25 moves, the push rod 41 on one side will extend to one side of the monitoring box 3, pushing the placing plate 42 to rotate from a vertical state to a horizontal state. At this time, the bird feed contained in the feed inclined groove 43 can flow to one side, facilitating the gathering of birds on the placing plate 42 later. On the contrary, the placing plate 42 on the other side will rotate back to the vertical state under the action of gravity after losing the push of the push rod 41, and will be firmly attracted to one side of the monitoring box 3 by the magnetic attraction force between the magnet blocks 46 and the iron layers, closing the hole and preventing air leakage.

[0069] In this way, the monitoring device not only can effectively monitor the particulate matter pollution in the atmospheric environment, but also can attract birds to stay through the placing plate 42 and the feed contained in the feed inclined groove 43, promoting the harmonious coexistence and coordinated development of urban and natural environment.
