Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust detection, and in particular to a dust detection device and method for urban management. BACKGROUND

[0002] For dust detection in urban management, real-time monitoring and remote control can be achieved based on Internet of Things technology. The specific implementation steps are as follows: install sensors: install dust sensors at key locations in the city, such as roads, construction sites, and river embankments. Optical sensors, particulate matter sensors, and other sensors can be used to monitor the concentration of dust particles in the air. Data collection and transmission: dust data collected by sensors in real time is uploaded to the cloud platform through Internet of Things technology. Data can be transmitted to designated servers or cloud platforms through wireless sensor networks or wired networks. Data processing and analysis: after the cloud platform receives the data uploaded by the sensor, it processes, analyzes, and stores the data. Data mining and machine learning algorithms can be used to analyze dust data and identify trends and anomalies. Warning and alarm: based on the analysis of dust data, appropriate warning thresholds can be set. Once the dust concentration exceeds the warning threshold, the system will automatically trigger the alarm mechanism and send an alert to the relevant personnel, and take appropriate handling and control measures. Remote control and management: through Internet of Things technology, real-time monitoring of data from each sensor can be achieved, and remote control can be performed.

[0046] A dust detection method applied to urban management, adopts a dust detection device applied to urban management, comprising the following steps:

[0047] Step one: install the device on the ground, so that the wind scoop 3 is opposite to the wind direction, and install the collection box at the bottom of the ash outlet 10;

[0048] Step two: the wind mechanism 6 will rotate under the action of wind force;

[0049] Step three: the power generated by the wind mechanism 6 will drive the air induction mechanism 7 to work, and air is introduced into the detection cylinder 2 through the wind scoop 3, and the dust detector 4 detects the air entering the detection cylinder 2;

[0050] Step four: the filtered air will be filtered by the air induction mechanism 7, and at the same time, the air induction mechanism 7 drives the management mechanism 8 to work;

[0051] Step five: the management mechanism 8 sprays water mist, and the filtered air of the air induction mechanism 7 is discharged to the outside environment;

[0052] Step six: when the air induction mechanism 7 filters the air entering the detection cylinder 2, the dredging mechanism 9 works, dredges the holes of the filter screen 75 used by the air induction mechanism 7, and cooperates with the cleaning brush 74 to clean the filter screen 75, and the dust after cleaning is discharged through the ash outlet 10.

[0053] In the application, when in use, first, the device is installed on the ground through the fixing seat 1, and the wind scoop 3 is opposite to the wind direction, then the water inlet pipe 85 is connected with the external water source, and the collection box is installed at the bottom of the ash outlet 10;

[0054] The wind wheel 64 will rotate under the action of wind force, and then drive the rotating rod 62 to rotate, so that the main bevel gear 63 drives the driven bevel gear 71 to rotate, and then the rotating shaft 72 rotates, and the rotation of the rotating shaft 72 drives the fan blade 73, the cleaning brush 74 and the connecting frame 81 and the structure of the dredging mechanism 9 except the tooth slot 91 to rotate;

[0055] The rotation of the fan blade 73 will draw the external air into the detection cylinder 2 through the air inlet 3, and under the guidance of the guide plate 5, the air enters the position where the dust detection instrument 4 is located, and the dust content in the air is detected by the dust detection instrument 4, and the data is sent to the remote control terminal after the detection is completed, and then the air is filtered by the filter screen 75, so that the dust in the air is retained on the air inlet side of the filter screen 75 and in the holes of the filter screen 75. At this time, due to the rotation of the cleaning brush 74, the dust on the air inlet side of the filter screen 75 will be cleaned, and the dust in the holes of the filter screen 75 will be cleaned by the dredging mechanism 9. The cleaning process is as follows:

[0056] Due to the rotation of the rotating shaft 72, the other structures on the dredging mechanism 9 except the gear groove 91 will revolve, at this time the gear 92 will rotate under the action of the gear groove 91, and then drive the reciprocating wire rod 93 to rotate, so that the sliding block 94 circulates along the inner side wall of the fixed frame 96. When the sliding block 94 slides to the position of the rotating shaft 72, it will press the air tank 98 through the air pipe 97 to make the air in the air tank 98 pass through the air pipe 97 and then be sprayed out of the dredging opening 95. In this process, since the sliding block 94 slides along the filter screen 75, when the dredging opening 95 slides to the position of the holes of the filter screen 75, the dust in the holes of the filter screen 75 will be blown out, and the cleaning brush 74 will be cleaned to ensure the filtering efficiency of the filter screen 75, thereby ensuring the detection efficiency of the air. The dust cleaned will enter the collection box under the action of the dust outlet 10, and the dust collected in the collection box will be cleaned by personnel regularly;

[0057] And in this process, due to the rotation of the connecting frame 81, the reciprocating rod 82 will move up and down, and then drive the piston plate 83 to slide up and down along the inner side wall of the piston cylinder 84. When the piston plate 83 slides up, it will draw water in the external water source into the piston cylinder 84 through the water inlet pipe 85. When the piston plate 83 slides down, it will press the water in the piston cylinder 84 into the treatment ring 87 through the water outlet pipe 86, and then be sprayed out of the water spraying hole 88. The water sprayed out of the water spraying hole 88 will enter the natural environment under the action of the air drawn and discharged by the fan blade 73, and condense the dust in the natural environment, so that the dust falls to the ground under the action of gravity, thereby further reducing the content of dust in the air and protecting the health of personnel.

[0058] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical scope disclosed by the present application and according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
