[0002] Air pollution monitoring is the process of determining the types and concentrations of pollutants in the atmosphere and observing their temporal and spatial distribution and patterns of change. The purpose of air pollution monitoring is to identify pollutants in the atmosphere, understand their distribution and diffusion patterns, and monitor emissions and control of air pollution sources.

[0003] In related technologies, when detecting suspended matter in the atmosphere, negative pressure is generally used to draw the gas in the atmospheric environment into a collecting mesh panel. This can collect and capture impurities and suspended matter in the atmosphere. Therefore, the basic quality of the atmosphere can be judged by observing the impurities on the mesh panel.

[0004] At present, the air quality detection devices in the existing technology are mostly used in work, and the equipment is mostly fixed with a mesh panel, which leads to poor practicality during detection, inconvenience for users to take out and replace the capture net in time, and the accuracy of the device during detection is relatively poor.

[0044] The present invention is described in further detail below in conjunction with the embodiments:

[0045] Example 1

[0046] like Figure 1-6 As shown, the present invention provides an air quality detection method and device, comprising a base plate 1 and two mounting plates 4, the outer walls of the two mounting plates 4 are each mounted with a negative pressure machine 5, the outsides of the two negative pressure machines 5 are each mounted with a collection assembly 6, and the air outlet ends of the two negative pressure machines 5 are each fixedly connected to an air outlet frame 7;

[0047] The collecting assembly 6 includes a frame 61 fixedly connected to the outer wall of the air outlet frame 7, and the side wall of the frame 61 is installed with a lifting motor 62 by bolts. The first rotating rod 63 is rotatably connected to both sides of the inner top of the frame 61, and the second rotating rod 65 is rotatably connected to both sides of the inner bottom of the frame 61. The outer wall of the first rotating rod 63 is fixedly connected to the first pulley 64, and the number of the first pulleys 64 is two. The outer wall of the second rotating rod 65 is fixedly connected to the second pulley 66, and the number of the second pulleys 66 is two. The outer walls of the two first pulleys 64 and the two second pulleys 66 are provided with belts 67, and the number of the belts 67 is two. The outside of the two belts 67 is installed with an installation assembly 8, and the number of the installation assembly 8 is two.

[0048] The output shaft of the lifting motor 62 and the first rotating rod 63 are connected by a keyway. The air outlet frame 7 and the frame 61 are made of aluminum alloy respectively. The keyway connection design facilitates the user to quickly disassemble and assemble the lifting motor 62 and the first rotating rod 63, and the aluminum alloy material also has a certain anti-rust effect and the advantages of light weight.

[0049] The two mounting components 8 form a relative moving structure through the cooperation between the two belts 67, the first rotating rod 63, the second rotating rod 65 and the lifting motor 62. During the transmission process of the belt 67, the bottom mounting component 8 will be driven to move upward, and the upper mounting component 8 will move downward under the influence of the bottom mounting component 8.

[0050] In this embodiment, when working, the user starts the lifting motor 62 to drive the first rotating rod 63 to rotate. The rotation of the first rotating rod 63 can control the rotation of the first pulley 64. The rotation of the first pulley 64 can control the belt 67 to drive the second pulley 66 and the second rotating rod 65 to rotate. During the transmission process of the belt 67, the bottom mounting assembly 8 will be driven to move upward, and the upper mounting assembly 8 will move downward under the influence of the bottom mounting assembly 8.

[0051] Example 2

[0052] like Figure 1-6 As shown, based on Example 1, the present invention provides a technical solution: the installation component 8 includes an installation box 81 fixedly connected to the outer wall of the belt 67, and slots 82 are provided on both sides of the installation box 81. A limiting groove 83 is provided on the upper surface of the installation box 81, and the number of the limiting grooves 83 is two, and the first capture plate 84 and the second capture plate 85 are respectively inserted into the two limiting grooves 83. This design structure is simple and convenient for users to quickly install the first capture plate 84 and the second capture plate 85, thereby facilitating user use.

[0053] The installation box 81 is made of aluminum alloy, and the first capture plate 84 and the second capture plate 85 are respectively made of fine-wool steel mesh weaving technology. The aluminum alloy material can make the installation box 81 more sturdy and stable, and the first capture plate 84 and the second capture plate 85 can also attach and collect suspended matter in the atmosphere well.

[0054] The two notches 82 and the two limit grooves 83 are connected. The inner diameter of the mesh of the first capture plate 84 is twice the inner diameter of the mesh of the second capture plate 85. This design can collect large suspended matter through the first capture plate 84, and the second capture plate 85 can collect and process small fluff or particles.

[0055] In this embodiment, the first capture plate 84 and the second capture plate 85 are sequentially inserted into the two limiting grooves 83 so that the first capture plate 84 and the second capture plate 85 are exposed on the two notches 82, thereby collecting and processing floating objects in the atmosphere.

[0056] Example 3

[0057] like Figure 1-6 As shown, based on Example 1, the present invention provides a technical solution: the upper surface of the base plate 1 is fixedly connected to the mounting frame 2, and a reciprocating mechanism 3 is installed inside the mounting frame 2. The reciprocating mechanism 3 includes a positioning plate 31 fixedly connected to the side wall of the mounting frame 2, and a reciprocating motor 32 is installed on the upper surface of the positioning plate 31 by bolts. The output shaft keyway of the reciprocating motor 32 is connected to the crankshaft 33, and the outer wall of the crankshaft 33 is sleeved with a sleeve 34, and the number of the sleeves 34 is two. The outer walls of the two sleeves 34 are fixedly connected to the limiting rod 35, and the outer ends of the two limiting rods 35 are rotatably connected to the sliding rod 36. By providing the reciprocating mechanism 3, such a design can perform back and forth reciprocating motion when the negative pressure machine 5 is working, thereby ensuring the accuracy during detection.

[0058] Both ends of the crankshaft 33 are rotatably connected to the inner wall of the mounting frame 2 by using bearings. The two sleeves 34 are made of aluminum alloy. The crankshaft 33 is used to control the movement of the negative pressure machine 5, which can make the negative pressure machine 5 more stable when working, and can make it work more efficiently and smoothly.

[0059] The front ends of the two slide rods 36 are fixedly connected to the backs of the two mounting plates 4, and the lengths of the two slide rods 36 are equal. When the lengths are equal, the synchronization frequency of the negative pressure machine 5 can be guaranteed, and it can also be ensured that no jamming occurs during the operation of the negative pressure machine 5.

[0060] The outer walls of the two slide rods 36 are slidably connected to the mounting frame 2. The two slide rods 36 form a reciprocating movable structure through two limit rods 35 and the crankshaft 33. The slide rods 36 can slide inside the mounting frame 2 during operation, which can ensure the stability of the overall operation of the slide rods 36. Secondly, the mounting frame 2 also has a higher load-bearing capacity.

[0061] In this embodiment, starting the reciprocating motor 32 can control the crankshaft 33 to rotate in the installation frame 2. The rotation of the crankshaft 33 can drive the sleeve 34 to rotate and control the limit rod 35 to drive the slide rod 36 to slide in the installation frame 2. In this way, the two slide rods 36 are affected by the crankshaft 33 and can move back and forth intermittently.

[0062] The following is a detailed explanation of the working principle of the atmospheric suspended matter detection system based on machine vision.

[0063] like Figure 1-6 As shown, first the user needs to place the base plate 1 to the place to be tested. Before the test, the user needs to start the negative pressure machine 5 to work in sequence, and then the user starts the reciprocating motor 32. The reciprocating motor 32 can control the crankshaft 33 to rotate in the installation frame 2. The rotation of the crankshaft 33 can drive the sleeve 34 to rotate and control the limit rod 35 to drive the slide rod 36 to slide in the installation frame 2. In this way, the two slide rods 36 are affected by the crankshaft 33 to move back and forth intermittently, so that the gas in the environment can be collected intermittently. After that, the first capture plate 84 and the second capture plate 85 are inserted into the two limit grooves 83 in sequence, so that the first capture plate 84 and the second capture plate 85 are exposed on the two notches 82, and the negative pressure machine 5 can remove the gas in the atmosphere from the outlet After the wind frame 7 is drawn into the first capture plate 84, it passes through the second capture plate 85, so that impurities in the atmosphere can be captured and collected in two stages, thereby being used for quality detection in the atmosphere. Finally, the lifting motor 62 is started to drive the first rotating rod 63 to rotate. The rotation of the first rotating rod 63 can control the rotation of the first pulley 64. The rotation of the first pulley 64 can control the belt 67 to drive the second pulley 66 and the second rotating rod 65 to rotate. During the transmission process of the belt 67, the bottom mounting assembly 8 will be driven to move upward, and the upper mounting assembly 8 will move downward under the influence of the bottom mounting assembly 8. In this way, the first capture plate 84 and the second capture plate 85 after collection can be taken out, and the new first capture plate 84 and the second capture plate 85 can be replaced in time.

[0064] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
