Description

Technical Field

[0001] The invention belongs to the technical field of air pollution detection, and relates to an air pollution monitoring device based on big data calculation. Background Art

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

[0003] Multiple air pollution detection devices are arranged according to the detection area, and the multiple air pollution detection devices are connected to the big data processing center. Each air pollution detection device includes multiple sensors, such as toxic gas sensors, PM2.5 sensors, dust sensors, etc., and also includes a base station. The sensor is used to collect air pollution parameters at the point. The base station realizes information exchange between the sensor and the big data processing center. The air pollution detection device transmits the measured data to the big data processing center after preprocessing. The big data processing center analyzes the received data and then performs real-time detection of air pollution in each area. The big data processing center includes a data preprocessing unit, a data clustering processing unit, an outlier detection unit, a database, etc.

[0004] At present, air pollution detection devices are often provided with vents for ventilation and heat dissipation. Since air pollution detection devices are often installed in environments with severe air pollution, when ventilation and heat dissipation are not needed, the vents need to be blocked to prevent harmful substances in the air from entering the interior of the installation shell through the air outlet, damaging electrical components, and shortening the service life of the air pollution monitoring device. However, the blocking method often involves directly inserting a plug into the vent for blocking. The plug and the vent are generally interference fit to achieve a sealing effect. In this way, the outer side of the plug will be worn due to the long-term plugging and unplugging operation of the plug with the vent, thereby affecting the subsequent sealing effect.

[0005] In addition, when collecting air, a filter is often required to prevent impurities such as hair and leaves from entering the air intake pipe. However, after the filter is used for a long time, impurities such as hair and leaves will clog the filter, affecting the air collection effect.

[0006] In order to solve the above problems, the present invention proposes an air pollution monitoring device based on big data calculation. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 6 As shown, the technical solution adopted by the present invention is as follows: an air pollution monitoring device based on big data calculation, including a box body 1, an electric turntable 19 is rotatably installed inside the box body 1, an air analyzer 18 is fixedly installed on the electric turntable 19, and the air inlet of the air analyzer 18 is connected to the exhaust pipe 8 through an exhaust pump. A first through hole is opened at the upper end of the box body 1, and a sealed bearing 17 is fixed at the first through hole. The exhaust pipe 8 is rotatably connected to the box body 1 through the sealed bearing 17. The air analyzer 18 is connected to the big data processing center. The air analyzer 18 includes multiple sensors, such as toxic gas sensors, PM2.5 sensors, dust sensors, etc., and multiple sensors are responsible for collecting different parameters of air pollution. The collected data is transmitted to the big data processing center through the base station, and the collected data is analyzed in the big data processing. The big data processing center includes a data preprocessing unit, a data clustering processing unit, an outlier detection unit, a database, etc.

[0040] One end of the air extraction pipe 8 extending outside the box body 1 is provided with a filter plate 9. The filter plate 9 can filter out debris such as hair and leaves, thereby preventing hair, leaves, etc. from entering the air extraction pipe 8, causing blockage and affecting the effect of collecting air.

[0041] The longitudinal section of the filter plate 9 is an arc-shaped surface, and the upper end surface of the exhaust pipe 8 matches the filter plate 9. The lower end of the filter plate 9 is hinged to the lower side of the upper end surface of the exhaust pipe 8 through a hinge shaft 10. A torsion spring is fixed between the filter plate 9 and the exhaust pipe 8 at the hinge shaft 10. The torsion spring keeps the filter plate 9 in contact with the upper end surface of the exhaust pipe 8. The filter plate 9 is divided into a fitting portion and a warping portion, and the fitting portion is in contact with the exhaust pipe 8. The warping portion is fixedly connected to the fitting portion, and the warping portion does not contact the exhaust pipe 8. The filter plate 9 is elastic and has the characteristic of automatic recovery.

[0042] One end of the air extraction pipe 8 having a filter plate 9 is provided with a cleaning mechanism. When the cleaning mechanism is in action, the filter plate 9 is cleaned to prevent the filter plate 9 from being blocked and affecting the collection of air.

[0043] The cleaning mechanism comprises a sliding sleeve 11 , a sliding rod 14 , a brush 16 , and a motor 13 .

[0044] The opposite side walls of the exhaust pipe 8 are symmetrically fixed with fixing frames 12, and the sliding sleeve 11 is rotatably installed between the two fixing frames 12. The sliding rod 14 is slidingly matched with the sliding sleeve 11. Ball bearings are arranged on the inner side of the sliding sleeve 11, and the arrangement of the ball bearings reduces the sliding friction between the sliding rod 14 and the sliding sleeve 11. Counterweight plates 15 are fixedly installed at both ends of the sliding rod 14. There are two brushes 16, which are fixedly arranged on the corresponding counterweight plates 15. The motor 13 is fixedly arranged on one side of the fixing frame 12, and the motor shaft of the motor 13 is drivingly connected to the sliding sleeve 11.

[0045] When the slide bar 14 is in a vertical state, the counterweight plate 15 at the upper end of the slide bar 14 contacts the sliding sleeve 11, the counterweight plate 15 at the lower end of the slide bar 14 is away from the sliding sleeve 11, and the height of the counterweight plate 15 and the brush 16 at the lower end is lower than the lowest end of the filter plate 9.

[0046] like Figure 2 As shown, the motor 13 works, driving the sleeve 11 to rotate counterclockwise, and at the same time driving the slide bar 14, the counterweight plate 15 and the brush 16 to rotate together. When the sleeve 11 rotates at an angle greater than 90 degrees, the slide bar 14 is in an inclined state. Under the action of the gravity of the counterweight plate 15 at the left end, the slide bar 14 will quickly slide to the left end along the inclined direction of the sleeve 11. When the counterweight plate 15 and the brush 16 at the left end contact the filter plate 9, they will impact the filter plate 9, causing the filter plate 9 to vibrate, and shaking off the impurities such as hair and leaves on the filter plate 9. At the same time, the brush 16 at the right end of the sleeve 11 is vibrated, causing the impurities on the right end brush 16 to fall off, thereby achieving the purpose of cleaning the right end brush 16. As the sleeve 11 continues to rotate, the brush 16 at the left end will move along the filter plate 9, thereby cleaning the filter plate 9.

[0047] A plurality of clearance grooves 2 are provided on the outer wall of the box body 1. A semicircular through hole 3 is provided at the clearance groove 2 of the box body 1. One end of the clearance groove 2 away from the semicircular through hole 3 is an inclined surface. The inclined surface is provided to reduce motion interference so that the stopper 5 can enter the clearance groove 2 more smoothly.

[0048] The outer surface of the box body 1 is provided with a baffle plate 4 which can cover all the clearance grooves 2, and a plurality of stoppers 5 which are adapted to the clearance grooves 2 are fixedly arranged on the baffle plate 4. An elastic rubber layer is fixedly arranged between the baffle plate 4 and the stoppers 5.

[0049] A driving assembly for driving the baffle 4 to move is provided on the side wall of the box body 1. The driving assembly drives the baffle 4, so that the baffle 4 drives the block 5, so that the block 5 gradually approaches the corresponding clearance groove 2, until the block 5 finally clings to the side wall of the clearance groove 2 of the box body 1, and blocks the semicircular through hole 3. The baffle 4 squeezes the block 5, and the elastic rubber layer is squeezed and deformed, so that the elastic rubber layer has prestress, so that the semicircular through hole 3 is blocked more tightly. The elastic rubber layer makes the connection between the baffle 4 and the block 5 have a certain flexibility, so that when the block 5 squeezes the semicircular through hole 3 upward, the elastic rubber layer deforms longitudinally, preventing the connection between the block 5 and the baffle 4 from being easily destroyed. In this way, it can prevent the polluted air from the outside from entering the interior of the box body 1 through the semicircular through hole 3 and corroding the internal electronic components.

[0050] When the semicircular through hole 3 needs to be opened, the driving member drives the baffle plate 4, so that the baffle plate 4 drives the stopper 5, so that the stopper 5 gradually moves away from the clearance groove 2, until the stopper 5 is completely separated from the clearance groove 2 and there is a certain distance. The semicircular through hole 3 is completely opened.

[0051] The driving assembly includes two groups of driving components, and the two groups of driving components are symmetrically arranged on both sides of the box body 1.

[0052] The driving parts include a connecting rod 6 and an electric telescopic rod 7. There are two connecting rods 6, which are parallel to each other. One end of the two connecting rods 6 is hinged to one end of the baffle 4, and the other end of the two connecting rods 6 is hinged to the side wall of the box body 1. The bases of the two electric telescopic rods 7 are hinged to the side wall of the box body 1, and the push rod of the electric telescopic rod 7 is hinged to the middle part of one of the connecting rods 6.

[0053] The electric telescopic rod 7 extends, pushing the connecting rod 6 to rotate around the hinge corresponding to the box body 1, and the connecting rod 6 pushes the baffle 4 to move away from the box body 1. Then the stopper 5 is driven to gradually leave the semicircular through hole 3 and the clearance groove 2, so that the semicircular through hole 3 is opened. The electric telescopic rod 7 contracts, driving the connecting rod 6 to rotate around the hinge between the connecting rod 6 and the box body 1, and driving the baffle 4 to move toward the box body 1.

[0054] A purification mechanism is provided on the side wall of the box 1. When it is necessary to dissipate heat for the air analyzer 18 and the controller 20 inside the box 1, the purification mechanism sends purified air into the box 1 to blow and dissipate heat for the air analyzer 18 and the controller 20, thereby preventing the heavily polluted air from corroding the air analyzer 18 and the controller 20.

[0055] The purification mechanism includes a purifier 22 and an air pump 23. A fixing plate 21 is fixedly arranged on the side wall of the box body 1, and the purifier 22 is fixedly mounted on the fixing plate 21. The air pump 23 is fixedly arranged on the purifier 22.

[0056] A circular shell 24 is fixedly provided on the inner wall of the box 1. The circular shell 24 is a cavity structure. A plurality of through holes 25 are evenly provided at one end of the circular shell 24 facing the air analyzer 18. The other end of the circular shell 24 is connected to the air outlet of the air pump 23 through an air outlet pipe. The air inlet of the air pump 23 is connected to the air outlet interface of the purifier 22 through the air inlet pipe.

[0057] The air purified and cooled by the purifier 22 enters the circular shell 24 under the action of the air pump 23, and enters the box 1 through the through hole 25 to dissipate heat and cool the electronic components in the box 1. The air in the box 1 is discharged to the outside through the semicircular through hole 3. The circular shell 24 increases the air outlet range of the air outlet pipe, so that the air from the air outlet pipe is blown to the air analyzer 18 more evenly and in a larger range.

[0058] A controller 20 and a temperature meter are provided inside the box 1. The controller 20 is electrically connected to the air analyzer 18, the temperature meter, the air pump 23, the purifier 22, the electric telescopic rod 7, and the electric turntable 19.

[0059] Rollers are provided at the bottom of the box 1 to facilitate the movement of the device.

[0060] Working principle:

[0061] In the initial state, the electric telescopic rod 7 is in a retracted state, the baffle 4 abuts against the side wall of the box body 1, and the block 5 abuts against the clearance groove 2 and the semicircular through hole 3, completely blocking the semicircular through hole 3. The slide bar 14 is in a vertical state, the counterweight plate 15 at the upper end of the slide bar 14 contacts the sliding sleeve 11, the counterweight plate 15 at the lower end of the slide bar 14 is away from the sliding sleeve 11, and the height of the counterweight plate 15 and the brush 16 at the lower end is lower than the lowest end of the filter plate 9.

[0062] When in use, move the box 1 to a suitable position. Start the electric turntable 19, which drives the air analyzer 18 and the exhaust pipe 8 to rotate until the top surface of the filter plate 9 is in a windward state. Then start the exhaust pump on the air analyzer 18, the external air is filtered by the filter plate 9, and then enters the air analyzer 18 through the exhaust pipe 8. The air analyzer 18 detects the air entering it. The air analyzer 18 transmits the detected data to the big data processing center after pre-processing, and the big data processing center analyzes the received data.

[0063] When the temperature in the box 1 is detected by the thermometer to reach a certain value, the air analyzer 18 and the controller 20 need to be cooled. The controller 20 starts the electric telescopic rod 7, the electric telescopic rod 7 is extended, and the electric telescopic rod 7 pushes the connecting rod 6 to move. The connecting rod 6 rotates around the hinge between it and the box 1, and the other end of the connecting rod 6 gradually moves away from the box 1, and drives the baffle 4 to gradually move away from the box 1. The baffle 4 drives the block 5 to gradually move away from the box 1 and moves downward relative to the box 1. The block 5 is gradually separated from the clearance groove 2 until the block 5 is out of the clearance groove 2 and the semicircular through hole 3 is opened. Then the electric telescopic rod 7 is closed. The purifier 22 and the air pump 23 are started. After the external air is purified and cooled by the air intake of the purifier 22, it enters the air pump 23 through the air intake pipe, then enters the round shell 24 through the air outlet pipe, and enters the box 1 through the through hole 25, and the air analyzer 18 and the controller 20 in the box 1 are cooled and cooled. The air in the box body 1 is discharged to the outside of the box body 1 through the semicircular through hole 3. When the thermometer detects that the temperature in the box body 1 drops to a certain value, the purifier 22, the air pump 23, and the electric telescopic rod 7 are turned off at the same time. The electric telescopic rod 7 contracts, driving the connecting rod 6 to rotate around the hinge between the connecting rod 6 and the box body 1. The baffle 4 moves toward the box body 1 under the drive of the connecting rod 6. The baffle 4 drives the block 5 to move synchronously, so that the block 5 gradually enters the clearance groove 2. Then the block 5 moves obliquely upward along the clearance groove 2 until the top of the block 5 abuts against the top of the semicircular through hole 3, and the right side of the block 5 abuts against the right side of the clearance groove 2. The block 5 completely blocks the semicircular through hole 3 to prevent the air polluted by the outside from entering the box body 1. At this time, the baffle 4 abuts against the side wall of the box body 1.

[0064] When the filter plate 9 needs to be cleaned, the motor 13 is started. At this time, the air analyzer 18 and the electric turntable 19 cannot be started. The motor 13 drives the sliding sleeve 11 to rotate slowly counterclockwise through the motor shaft, and the sliding sleeve 11 drives the sliding rod 14, the counterweight plate 15, and the brush 16 to rotate simultaneously. When the rotation angle of the sliding sleeve 11 is greater than 90°, the sliding rod 14 is in an inclined state. And the right end of the sliding rod 14 is inclined upward, and the left end of the sliding rod 14 is inclined downward. Under the gravity of the counterweight plate 15 at the left end, the sliding rod 14 moves rapidly to the left end along the sliding sleeve 11 in the inclined direction. Under the action of inertia, the counterweight plate 15 and the brush 16 at the left end will impact the raised part of the left end of the filter plate 9. The contact position of the filter plate 9 along the left line of the exhaust pipe 8 and the filter plate 9 is elastically deformed. After the elastic deformation of the filter plate 9, it will automatically recover and generate vibration. The impurities on the filter plate 9 are subjected to vibration force, causing some of the impurities to bounce to the right, and also causing some impurities stuck on the filter plate 9 to be loosened, which is convenient for subsequent cleaning. At the same time, the brush 16 at the right end of the slide bar 14 is also subjected to a certain vibration force to cause the impurities to separate, playing the role of cleaning the brush 16 at the right end. When the filter plate 9 is restored to its initial state after elastic deformation, some impurities will fly to the right away from the filter plate 9 under the action of inertia, causing some impurities stuck on the filter plate 9 to be loosened.

[0065] Then, as the sleeve 11 rotates, the brush 16 at the left end moves against the filter plate 9 to clean the filter plate 9. When the sleeve 11 rotates to 180°, the counterweight plate 15 and the brush 16 originally at the upper end sweep the filter plate 9 and then separate from the filter plate 9 and are located at the lower end of the sleeve 11, while the counterweight plate 15 and the brush 16 originally at the lower end are located at the upper end of the sleeve 11. As the sleeve 11 continues to rotate, the counterweight plates 15 and the brush 16 at both ends of the slide rod 14 will alternately repeat the above actions, thereby cleaning the filter plate 9.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
