DETAILED DESCRIPTION

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] like Figure 1-Figure 9 As shown, an atmospheric pollution detection device comprises: an atmospheric detector body 1, the atmospheric detector body 1 comprises a chassis 11, side wing plates 12 are fixedly arranged on both sides of the chassis 11, an anemometer 13 is arranged on the side wing plates 12, a support rod 14 is arranged on the chassis 11, a particle collector 15 for classifying and collecting particulate matter in the atmosphere is arranged on the support rod 14, a protective screen 16 is fixedly arranged in the air inlet of the particle collector 15, and a net cleaning component 2 for cutting flocs in the mesh of the protective screen 16 and shaking off the dust is arranged on the outer wall of the protective screen 16, the atmospheric detector body 1 is erected in an outdoor detection area, the wind speed is detected by the anemometer 13, and the air is controlled to enter the particle collector 15 in a timely manner by the control system in the chassis 11, and different atmospheric particulate matter is collected by the particle collector 15 for detecting atmospheric pollution. When the air enters the particle collector 15, it needs to pass through the mesh of the protective screen 16 first, and the flocs in the air are blocked by the protective screen 16;

[0032] The net cleaning assembly 2 includes a cutting net ring 22 whose height is smaller than that of the protective screen 16. The meshes of the cutting net ring 22 are aligned with the meshes of the protective screen 16 and the two are tightly fitted. A pad 23 fixedly connected to the shell of the particle collector 15 is arranged on the outer side of the cutting net ring 22. A push column 24 is fixedly arranged on the pad 23 for pushing and pulling the cutting net ring 22 to rotate and clean the floccules and accumulated dust in the mesh. The air is regularly sucked into the particle collector 15, and the floccules in the air are hung on the meshes of the protective screen 16 like a spider web. When the collector 15 stops working, the control system in the chassis 11 controls the electromagnet 5 to work, and the electromagnet 5 pulls the branch pull wire 401 to control the soot blowing assembly 4 to supply air to the push column 24. The electromagnet 5 can be installed in any appropriate position, and the push column 24 pushes the cutting net ring 22 to rotate slightly, so that the meshes of the cutting net ring 22 and the protective partition 16 are interlaced with each other, so that the floccules hanging on the meshes of the protective partition 16 are cut like scissors, which is conducive to automatically cleaning the floccules and reducing the impact on the air entering the particle collector 15;

[0033] By reciprocating the extension and retraction of the push column 24, the cutting net ring 22 is reciprocated for many times, which is beneficial to the vibration of the cutting net ring 22, and is beneficial to shaking off the particles and dust adsorbed on the cutting net ring 22 and the protective isolation net 16. In addition, each counterclockwise rotation of the cutting net ring 22 can cause the meshes of the two to be misaligned, thereby blocking the meshes, which is beneficial to reduce the entry of dust during shaking;

[0034] The input end of the push column 24 is connected to a soot blowing assembly 4 for supplying air to it and blowing soot in two directions on the mesh of the cutting mesh ring 22. When the particle collector 15 stops working, the electromagnet 5 simultaneously pulls the branch pull wire 401 that controls the air baffle 49, so that the high-pressure gas in the air storage main box 43 can enter the air guide ring 1 41 and the air guide ring 2 42 and be ejected in sequence from the jet port 1 44 and the jet port 2 45, so as to blow away the dust particles adsorbed on the cutting mesh ring 22.

[0035] The push column body 24 includes a piston telescopic column 25, and the top of the piston telescopic column 25 is fixedly connected to the side wall of the cutting net ring 22 through a wire, and the bottom wall of the piston telescopic column 25 is fixedly provided with a plurality of pull wires 26. The side wall of the push column body 24 is provided with an exhaust hole 29, and the air in the air chamber 247 is filled into the push column body 24. The increase in air pressure pushes the piston telescopic column 25 to extend, thereby pushing the cutting net ring 22 to rotate clockwise, like a pair of scissors to cut the flocs hanging on the mesh of the protective partition net 16, which is conducive to automatically cleaning the flocs.

[0036] A cross-shaped elastic sheet 28 is slidably disposed on the inner side of the exhaust hole 29 , and a rubber sheet 201 is fixedly disposed on the inner side of the elastic sheet 28 . The diameter of the rubber sheet 201 is larger than the diameter of the exhaust hole 29 , and the diameter of the exhaust hole 29 is smaller than the length of the elastic sheet 28 .

[0037] A plurality of air vents 202 are provided on the outer ring of the rubber sheet 201, and the dimensions of the plurality of air vents 202 from the center of the rubber sheet 201 are greater than the radius of the exhaust hole 29. A pull wire 27 penetrating the bottom wall ring of the push column 24 and connected to the piston telescopic column 25 is fixedly provided at the center of the rubber sheet 201. When the piston telescopic column 25 rises, the pull wire 27 can be pulled, and the rubber sheet 201 and the elastic sheet 28 are pulled to slide by the pull wire 27, so that the air vent 202 leaks out into the exhaust hole 29. At this time, the air in the push column 24 is quickly discharged, and the piston telescopic column 25 is reset under the pull of the pull wire 26. The exhaust hole 29 is sealed again through the rubber sheet 201 under the elasticity of the elastic sheet 28. This reciprocating action can reciprocately drive the cutting net ring 22 to rotate and vibrate.

[0038] The sootblowing assembly 4 includes an air guide ring 41 fixedly connected to the inner wall of the air inlet of the particle collector 15, and an identical air guide ring 42 is arranged parallel to the lower side of the air guide ring 41, and a plurality of air storage main boxes 43 are fixedly arranged between the air guide ring 42 and the air guide ring 41, and the plurality of air storage main boxes 43 are interconnected by pipelines, and the inner walls of the air guide ring 42 and the air guide ring 41 are respectively provided with a jet port 1 44 and a jet port 2 45 with opposite blowing directions.

[0039] The interior of the main air storage box 43 is provided with air chamber 1 46, air chamber 2 47 and air chamber 3 48 from top to bottom, and air chamber 1 46, air chamber 2 47 and air chamber 3 48 are not connected to each other. The air inlet end of the main air storage box 43 is provided with a power mechanism 3 for providing gas to the soot blowing assembly 4.

[0040] The output air outlets of air chamber one 46, air chamber two 47 and air chamber three 48 are all rotatably provided with an air baffle plate 49, to which a branch pull wire 401 is fixedly connected, and the branch pull wires 401 of the air baffle plates 49 of air chamber one 46, air chamber two 47 and air chamber three 48 have different lengths. The length of the branch pull wire 401 on air chamber three 48 is greater than the length of the branch pull wire 401 on air chamber three 48, and the length of the branch pull wire 401 on air chamber three 48 is greater than the length of the branch pull wire 401 on air chamber two 47. When the branch pull wire 401 is pulled by the electromagnet 5, the air is ejected downward from the air jet port one 44 while tilting upward, and then the air is ejected downward from the air jet port two 45, so that the dust that has been shaken off and blown away can be blown downward, which is beneficial to reduce the secondary adsorption of dust therein.

[0041] The power mechanism 3 comprises a protection box 31 fixed on the anemometer 13 , an air storage box 33 is fixedly arranged inside the protection box 31 , and an extrusion sheet is rotatably arranged on one side of the air storage box 33 close to the rotating column of the anemometer 13 .

[0042] An air bag 34 is arranged in the air storage box 33, and an auxiliary force plate 32 fixedly connected to the rotating column of the anemometer 13 is arranged on one side of the extrusion plate of the air storage box 33. The rotation of the anemometer 13 can drive the auxiliary force plate 32 to rotate, and the air bag 34 is squeezed by the auxiliary force plate 32, so that the air in the air bag 34 is discharged into the air blocking head 36 through the air supply pipe 35.

[0043] The output end of the airbag 34 is connected to an air supply pipe 35, and the end of the air supply pipe 35 away from the protective box 31 is connected to an air blocking head 36. A frustum-shaped internal resistance head 37 is slidingly arranged inside the air blocking head 36. A sealing gasket 38 is fixedly arranged on the conical surface of the internal resistance head 37, and a spring 39 is fixedly arranged on the cylindrical end of the internal resistance head 37. When air hits the internal resistance head 37, the internal resistance head 37 can slide backward, allowing air to enter air chamber 1 46, air chamber 2 47 and air chamber 3 48 respectively, providing them with gas for cleaning dust.

[0044] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
