[0001] The present invention relates to the technical field of atmosphere monitoring, in particular to an atmospheric environment monitoring device. Background Art

[0002] With the acceleration of industrialization and the continuous increase of human activities, the quality of the atmospheric environment has received increasing attention. For the sake of human health, various toxic and harmful gases contained in the atmosphere need to be closely monitored. As an important tool for evaluating and protecting the atmospheric environment, the development of atmospheric environment monitoring equipment has important practical significance. General atmospheric environment monitoring equipment is divided into fixed-point monitoring and mobile monitoring. Fixed-point monitoring generally sets up monitoring equipment at a higher position or in an extreme environment. When the gas flow rate is relatively slow and stable, the gas particles floating into the monitoring equipment are monitored to ensure that the obtained gas particle content in the atmosphere is more accurate.

[0003] However, in the process of atmospheric environment monitoring, when external gas enters the monitoring equipment through the air pipe, some impurity particles in the atmosphere will adhere to the inner wall of the pipe due to humidity or charged characteristics. Personnel need to climb to a high place or enter a special environment to clean the inner wall of the air pipe, which is very troublesome. In addition, the dust or dirt attached to the inner wall of the pipe is composed of a variety of particles in the atmosphere with complex composition. If it is not cleaned frequently, the emitted particles will float into the monitoring equipment with the atmosphere, resulting in other impurities in the monitoring results, seriously affecting the accuracy of the monitoring results. Therefore, according to the applicant's invention, a device is invented that can remove dust attached to the inner wall of the air pipe, which solves the problem of inconvenient cleaning of the air intake pipe of the monitor and preventing dust backflow.

The conical The internal annular array of the sleeve is distributed with ash discharge holes. The dust on the inner wall of the air inlet cylinder is scraped off by the positive rotation of the arc-surface inclined scraper strip, and the dust is blown out by the airflow generated by the wind plate. When the wind direction blows from the outside of the air inlet cylinder to the inside, a high-speed airflow is formed when the external airflow contacts the inclined surface of the conical sleeve, and the airflow velocity entering along the inner wall is lower than the high-speed airflow on the inclined surface, thereby forming an air pressure difference between the inside and the outside, causing the airflow to be discharged outward through the ash discharge holes, so that the internal dust can still be sucked out through the ash discharge holes in headwind weather.

[0010] Preferably, the point spraying mechanism includes a gas tank, an air pump and an air pipe, the side surface of the gas tank is fixedly connected to the mounting frame, the upper surface of the gas tank is fixedly connected to the air pump, a valve for adding nitrogen is provided below the gas tank, the output end of the air pump is fixedly connected to the air pipe, and a pressure switch is provided on the inner wall of the air inlet cylinder, which can open or close the air pump when squeezed by the arc surface of the arc-surface oblique scraper strip.

[0014] The present invention provides an atmospheric environment monitoring device, which has the following beneficial effects: 1. The wind wheel can drive the transmission device to rotate under the action of wind force, and then drive the rotating ring to rotate, so as to achieve more reasonable utilization of wind energy, save electricity, and be more environmentally friendly. At the same time, the rotating ring drives the arc-shaped oblique scraper to rotate on the inner wall of the air intake cylinder to scrape off the dust or dirt on the inner wall, so as to clean the inner wall of the air intake cylinder, thereby avoiding other impurities in the monitoring results and improving the accuracy of the results. There is no need to manually climb up the mounting frame for operation, which not only improves the safety during the cleaning process, but also greatly improves the convenience.

[0015] 2. By designing the driving device and the transmission device, it is achieved that in windy weather, no matter whether the wind wheel rotates forward or reversely, the third shaft can only rotate in one direction, which prevents the reverse rotation of the arc-surface oblique scraping strip and the backflow of scraped dust into the gas monitor body. In the process of forward rotation, the arc-surface oblique scraping strip continuously squeezes the pressure switch, and the nitrogen in the gas tank is intermittently sprayed out from the point spray hole through the air pump, blowing off the dust on the rear end of the monitoring mirror and the inner wall of the air intake cylinder, and then the wind plate set on the arc-surface oblique scraping strip generates an outward airflow to blow the dust to the outside of the air intake cylinder, further preventing the dust from backflowing during the scraping process. At the same time, due to the unique inclined design of the arc-surface oblique scraping strip, it is relatively After being scraped, large dirt will be pushed to the edge of the inner wall of the air intake cylinder along the inclined surface of the arc-surface scraper strip and then discharged. In the process of rotation of the arc-surface scraper strip, due to the existence of a centrifugal force, the arc-surface scraper strip will be close to the inner wall of the air intake cylinder, making the cleaning more thorough. When the wind direction blows from the outside to the inside of the air intake cylinder, a high-speed airflow will be formed when the external airflow contacts the inclined surface of the conical sleeve, and the airflow velocity entering along the inner wall is lower than the high-speed airflow on the inclined surface, thereby forming an air pressure difference between the inside and the outside, causing the airflow to be discharged outward through the ash discharge hole. Even in such weather when the wind direction blows from the outside to the inside of the air intake cylinder, the internal dust can still be sucked out through the ash discharge hole, thereby achieving dust cleaning.

[0021] The gas monitoring device includes a gas monitor body 19, an air intake cylinder 20, and a dust cleaning component arranged on the inner wall of the air intake cylinder 20. The right surface of the gas monitor body 19 is fixedly connected to the air intake cylinder 20. A monitoring mirror 28 is arranged inside the air intake cylinder 20. The dust cleaning component includes a swivel 21, an arc-shaped oblique scraping strip 22, a wind plate 41 arranged on the arc-shaped oblique scraping strip 22, and a point spray mechanism. A groove is arranged in the middle of the swivel 21, and an annular tooth 23 is arranged on the inner wall of the groove. The gear 18 passes through the opening 40 arranged on the air intake cylinder 20 and is meshed with the annular tooth 23. The right surface of the swivel 21 is fixedly connected to the arc-shaped oblique scraping strips 22 which are distributed in an annular shape and are four in number. The side surface of the arc-shaped oblique scraping strip 22 is connected to the air intake cylinder 20. The inner wall of the cylinder 20 is fitted, and a conical sleeve 37 is fixedly connected to the right end of the air inlet cylinder 20. The inner ring array of the conical sleeve 37 is provided with ash discharge holes 44. The point spray mechanism includes a gas tank 24, an air pump 25 and an air pipe 26. The side surface of the gas tank 24 is fixedly connected to the mounting frame 1, and the upper surface of the gas tank 24 is fixedly connected to the air pump 25. A valve 29 for adding nitrogen is provided below the gas tank 24, and the output end of the air pump 25 is fixedly connected to the air pipe 26. A pressure switch 30 is provided on the inner wall of the air inlet cylinder 20. The interior of the air inlet cylinder 20 is provided with a plurality of point spray holes 27 with an inclination angle of 45° and distributed in an annular shape. The upper end of the air pipe 26 passes through the interior of the gas monitor body 19 and is connected with the point spray holes 27.

[0022] The transmission device includes a second bevel gear 10, a second rotating shaft 11, a third rotating shaft 17, a gear 18, a non-return assembly for connecting the second rotating shaft 11 and the third rotating shaft 17, and a limit assembly for limiting the reverse rotation of the gear 18. The right surface of the second bevel gear 10 is fixedly connected to the second rotating shaft 11, and the right end of the third rotating shaft 17 is fixedly connected to the gear 18.

[0023] In the present embodiment, under windy conditions, the gear 18 drives the swivel 21 to rotate through the cooperation of the rotating device and the transmission device, and the swivel 21 drives the arc-shaped oblique scraping strip 22 to rotate inside the air intake cylinder 20. The arc-shaped oblique scraping strip 22 scrapes off the dust or dirt on the inner wall of the air intake cylinder 20 during the rotation process, and the pressure switch 30 is pressed once during each rotation of the arc-shaped oblique scraping strip 22. The air pump 25 is started by the pressure switch 30 to spray the nitrogen in the air tank 24 through the air pipe 26 from the point spray hole 27 to achieve point spraying. By point spraying nitrogen, the dust on the inner wall of the rear end of the monitoring mirror 28 and the air intake cylinder is blown off and ejected outward by the uninterrupted impact force of the airflow. At the same time, the wind plate 41 on the arc-shaped oblique scraping strip 22 also generates airflow during the rotation process, and the airflow blows off the mixture of the scraped off by the arc-shaped oblique scraping strip 22 and the nitrogen. Dust is blown out of the air inlet cylinder 20 to prevent dust backflow. At the same time, the curved inclined scraper strip 22 is affected by centrifugal force during rotation. As the rotation speed increases, it will become closer and closer to the inner wall of the air inlet cylinder 20, thereby improving the cleaning effect. Due to the unique inclined surface design of the curved inclined scraper strip 22, larger dirt will be pushed to the edge of the inner wall of the air inlet cylinder 20 along the inclined surface of the curved inclined scraper strip 22 after scraping and discharged. When the wind direction blows from the outside of the air inlet cylinder 20 to the inside, a high-speed airflow is formed when the external airflow contacts the outer inclined surface of the conical sleeve 37, while the airflow velocity entering along the inner wall is lower than the high-speed airflow on the inclined surface, thereby forming an air pressure difference between the inside and the outside, causing the airflow to be discharged outward through the dust discharge hole 44, so that even in weather where the wind direction blows from the outside of the air inlet cylinder 20 to the inside, the internal dust can still be sucked out through the dust discharge hole 44, thereby achieving dust cleaning.
