Description

Technical Field

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

[0002] With the acceleration of the industrialization process and the continuous increase of human activities, the quality of the atmospheric environment has been increasingly concerned. For the physical health of humans, various toxic and harmful gases contained in the atmosphere need to have their data closely monitored. As an important tool for evaluating and protecting the atmospheric environment, the development of atmospheric environment monitoring equipment has important practical significance. Generally, atmospheric environment monitoring equipment is divided into two types: fixed-point monitoring and mobile monitoring. Fixed-point monitoring generally installs the monitoring equipment at a higher position or in an extreme environment. When the gas flow rate is relatively slow and stable, it monitors the gas particles floating into the interior of the monitoring equipment, so as to ensure that the content of gas particles in the atmosphere obtained is more accurate.

[0003] However, during the process of atmospheric environment monitoring, when external gas enters the monitoring equipment through the trachea, some impurity particles in the atmosphere will adhere to the inner wall of the pipeline due to humidity or electrical properties. Personnel need to climb to high places or enter special environments to clean the inner wall of the trachea pipeline, which is very troublesome. Moreover, the dust or dirt adhering to the inner wall of the pipeline is composed of various particulate matters in the atmosphere, with complex components. If not cleaned regularly, the particulate matters emitted will float into the monitoring equipment together with the atmosphere, resulting in other impurities in the monitoring results and seriously affecting the accuracy of the monitoring results. Therefore, according to the invention of the applicant, a device capable of removing the dust adhering to the inner wall of the trachea is invented, which solves the problems of inconvenient dust cleaning of the intake pipe of the monitor and preventing dust backflow. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An atmospheric environment monitoring device includes a mounting frame. A meteorological device for monitoring the wind direction is provided at the left end of the mounting frame, a gas monitoring device for monitoring gases is provided at the right end of the mounting frame, a transmission device is provided between the meteorological device and the gas monitoring device, and an alarm lamp is fixedly connected to the upper surface of the mounting frame;

[0005] The meteorological device includes a meteorological instrument body, a weather vane, and a rotating assembly for driving provided at the upper end of the meteorological instrument body. The side surface of the meteorological instrument body is fixedly connected to the mounting frame, and the lower end of the meteorological instrument body is rotatably connected to the weather vane;

[0006] The gas monitoring device includes a gas monitor body, an intake cylinder, and a dust cleaning assembly provided on the inner wall of the intake cylinder. The right surface of the gas monitor body is fixedly connected to the intake cylinder, and a monitoring mirror is provided inside the intake cylinder;

[0007] The transmission device includes a second bevel gear, a second rotating shaft, a third rotating shaft, a gear, a reverse prevention component for connecting the second rotating shaft and the third rotating shaft, and a limit component for restricting the reverse rotation of the gear. The right surface of the second bevel gear is fixedly connected to the second rotating shaft, and the right end of the third rotating shaft is fixedly connected to the gear.

[0008] Preferably, the rotating component includes a wind wheel, a first rotating shaft, and a first bevel gear. The upper end of the weather instrument body is rotatably connected to the wind wheel. The upper surface of the wind wheel is fixedly connected to the first rotating shaft. The upper end of the first rotating shaft is fixedly connected to the first bevel gear. The side surface of the first bevel gear is meshed and connected to the second bevel gear.

[0009] Preferably, the reverse prevention component includes a ratchet wheel, an outer wheel, a positioning column, a pawl, a spring piece, and an adjusting mechanism. The inside of the ratchet wheel is rotatably connected to a positioning shaft. The right end of the positioning shaft is fixedly connected to the outer wheel. The left inner wall of the outer wheel is fixedly connected to the positioning column. The side surface of the positioning column is rotatably connected to the pawl. The side surface of the spring piece contacts the pawl. The right end of the second rotating shaft is fixedly connected to the ratchet wheel. The left end of the third rotating shaft is fixedly connected to the outer wheel. By the pawl engaging into the ratchet wheel, the ratchet wheel drives the outer wheel to rotate forward. When the ratchet wheel rotates in reverse, the pawl will disengage from the ratchet wheel, causing the ratchet wheel to rotate idly, so that no matter what the wind direction is, the arc-shaped inclined scraping strip can only rotate in one direction, preventing dust from flowing back during the dust cleaning process.

[0010] Preferably, the adjusting mechanism includes an adjusting bolt and a limit nut. The side surface of the adjusting bolt is threadedly connected to the outer wheel. The lower end of the adjusting bolt is rotatably connected to the spring piece. The side surface of the adjusting bolt is threadedly connected to the limit nut. By turning the adjusting bolt, the spring piece can be adjusted, thereby adjusting the pressure of the spring piece on the pawl, preventing the mismatch between the ratchet wheel and the pawl due to insufficient elasticity after long-term use. And the limit nut is used to prevent the adjusting bolt from loosening during rotation, improving the durability of the reverse prevention component.

[0011] Preferably, the limit component includes a first fixing frame, a torsion spring, a second pawl, and reverse teeth annularly distributed on the side surface of the third rotating shaft. The upper surface of the gas monitor body is fixedly connected to the first fixing frame. The side surface of the third rotating shaft is rotatably connected to the first fixing frame. The inside of the first fixing frame is rotatably connected to the second pawl. One end of the torsion spring is fixedly connected to the second pawl. The other end of the torsion spring is fixedly connected to the first fixing frame. Through the limit component, when the third rotating shaft rotates slightly in reverse, the second pawl will engage into the reverse teeth, preventing the second rotating shaft from driving the third rotating shaft to rotate slightly in reverse during idling, further improving the stability of the device.

[0012] Preferably, the dust cleaning assembly includes a rotating ring, an arc-shaped inclined scraping strip, a wind plate arranged on the arc-shaped inclined scraping strip, and a point spraying mechanism. A groove is arranged in the middle of the rotating ring, and a ring-shaped tooth is arranged on the inner wall of the groove. The gear passes through an opening arranged on the air inlet cylinder and is meshed and connected with the ring-shaped tooth. The right surface of the rotating ring is fixedly connected with four arc-shaped inclined scraping strips distributed in a ring shape. The side surface of the arc-shaped inclined scraping strip is attached to the inner wall of the air inlet cylinder. A conical socket is fixedly connected to the right end of the air inlet cylinder. Dust discharging holes are annularly and arrayedly distributed inside the conical socket. The dust on the inner wall of the air inlet cylinder is scraped off by the forward rotation of the arc-shaped inclined scraping strip, and the dust is blown out by the airflow generated by the wind plate. And when the wind direction blows from the outside to the inside of the air inlet cylinder, the external airflow will form a high-speed airflow when contacting the inclined surface of the conical socket, and the airflow flowing along the inner wall has a lower flow rate than the high-speed airflow on the inclined surface. Thus, an air pressure difference is formed inside and outside, so that the airflow is discharged outward through the dust discharging holes, and the internal dust can still be sucked out through the dust discharging holes in adverse wind weather.

[0013] Preferably, the point spraying mechanism includes an air tank, an air pump and an air pipe. The side surface of the air tank is fixedly connected with a mounting frame. The upper surface of the air tank is fixedly connected with the air pump. A valve for adding nitrogen is arranged below the air tank. The output end of the air pump is fixedly connected with the air pipe. A pressure switch is arranged on the inner wall of the air inlet cylinder. When being extruded by the arc surface of the arc-shaped inclined scraping strip, the air pump will be turned on or off.

[0014] Preferably, a plurality of point spraying holes with an inclination angle of 45° and distributed in a ring shape are arranged inside the air inlet cylinder. The upper end of the air pipe passes through the inside of the gas monitor body and is communicated with the point spraying holes, for spraying nitrogen to blow off and rebound the dust on the monitoring mirror and the rear end of the inner wall of the air inlet cylinder, and the dust is carried out by the airflow generated by the rotation of the dust cleaning assembly, further improving the dust cleaning effect.

[0015] Preferably, a second fixing frame is fixedly connected to the upper surface of the mounting frame. The lower surface of the second rotating shaft is rotatably connected with the second fixing frame. The side surface of the third rotating shaft is rotatably connected with the second fixing frame, for improving the equipment stability when the driving device and the transmission device rotate.

[0016] Preferably, a screw rod is threadedly connected inside the mounting frame. The lower end of the screw rod is drivingly connected with a motor. The lower surface of the motor is fixedly connected with a base. Two symmetrically distributed guiding sliding columns are fixedly connected to the upper surface of the base. The side surface of the guiding sliding column is slidably connected with the mounting frame, for lifting and lowering the equipment above, facilitating maintenance and repair.

[0017] The present invention provides an atmospheric environment monitoring device, which has the following beneficial effects:

[0018] 1. The wind wheel can drive the transmission device to rotate under the action of wind force, thereby driving the rotating ring to rotate, so as to achieve a more reasonable utilization of wind energy, save electric energy, and be more environmentally friendly. At the same time, the rotating ring drives the arc-shaped inclined scraping strip to rotate on the inner wall of the air intake cylinder to scrape off the dust or dirt on the inner wall, realizing the dust cleaning of the inner wall of the air intake cylinder, thereby avoiding other impurities in the monitoring results and improving the accuracy of the results. Moreover, there is no need for manual climbing on the installation frame for operation, which not only improves the safety during the dust cleaning process but also greatly improves the convenience.

[0019] 2. By designing the driving device and the transmission device, it is realized that in windy weather, regardless of whether the wind wheel rotates forward or backward, the third rotating shaft can only rotate in one direction, preventing the arc-shaped inclined scraping strip from rotating reversely and causing the scraped dust to pour back into the internal part of the gas monitor body. And during the forward rotation process of the arc-shaped inclined scraping strip, the pressure switch is continuously pressed, and nitrogen in the gas tank is intermittently ejected from the point injection holes by the air pump to blow off the dust on the monitoring mirror and the rear end of the inner wall of the air intake cylinder. Then, the air plate arranged on the arc-shaped inclined scraping strip generates an outward airflow to blow the dust to the outside of the air intake cylinder, further preventing the dust from pouring back during the scraping process. At the same time, due to the unique inclined surface design of the arc-shaped inclined scraping strip, larger dirt will be pushed along the inclined surface of the arc-shaped inclined scraping strip to the edge of the inner wall of the air intake cylinder and then discharged. And during the rotation process of the arc-shaped inclined scraping strip, due to the existence of a centrifugal force, the arc-shaped inclined scraping strip will be tightly attached to the inner wall of the air intake cylinder, making the cleaning more thorough. When the wind blows from the outside to the inside of the air intake cylinder, the external airflow will form a high-speed airflow when contacting the inclined surface of the conical sleeve head, and the airflow entering along the inner wall has a lower flow rate than the high-speed airflow on the inclined surface, thus forming a pressure difference inside and outside, enabling the airflow to be discharged outward through the dust discharge holes. Even in the weather when the wind blows from the outside to the inside of the air intake cylinder, it is still possible to suck out the internal dust through the dust discharge holes, thereby realizing dust cleaning.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] As Figures 1-8 shown, the embodiment of the present invention provides an atmospheric environment monitoring device, including a mounting frame 1. A weather device for monitoring the wind direction is provided at the left end of the mounting frame 1, a gas monitoring device for monitoring gas is provided at the right end of the mounting frame 1, a transmission device is provided between the weather device and the gas monitoring device, and an alarm lamp 39 is fixedly connected to the upper surface of the mounting frame 1.

[0032] The weather device includes a weather instrument body 5, a wind vane 7, and a rotating assembly for driving provided at the upper end of the weather instrument body 5. The side surface of the weather instrument body 5 is fixedly connected to the mounting frame 1, and the lower end of the weather instrument body 5 is rotatably connected to the wind vane 7.

[0033] The gas monitoring device includes a gas monitor body 19, an intake cylinder 20, and a dust cleaning component provided on the inner wall of the intake cylinder 20. The right surface of the gas monitor body 19 is fixedly connected to the intake cylinder 20. A monitoring mirror 28 is provided inside the intake cylinder 20. The dust cleaning component includes a rotating ring 21, an arc-shaped inclined scraping strip 22, a wind plate 41 provided on the arc-shaped inclined scraping strip 22, and a point spraying mechanism. A groove is provided in the middle of the rotating ring 21, and a ring-shaped tooth 23 is provided on the inner wall of the groove. A gear 18 passes through an opening 40 provided on the intake cylinder 20 and meshes with the ring-shaped tooth 23. The right surface of the rotating ring 21 is fixedly connected to four arc-shaped inclined scraping strips 22 distributed in a ring shape. The side surface of the arc-shaped inclined scraping strip 22 is attached to the inner wall of the intake cylinder 20. A conical socket 37 is fixedly connected to the right end of the intake cylinder 20. Dust discharge holes 44 are annularly and arrayedly distributed inside the conical socket 37. The point spraying mechanism includes a gas tank 24, a gas pump 25, and a gas pipe 26. The side surface of the gas tank 24 is fixedly connected to a mounting frame 1. The upper surface of the gas tank 24 is fixedly connected to the gas pump 25. A valve 29 for adding nitrogen is provided below the gas tank 24. The output end of the gas pump 25 is fixedly connected to the gas pipe 26. A pressure switch 30 is provided on the inner wall of the intake cylinder 20. A plurality of point spraying holes 27 with an inclination angle of 45° and distributed in a ring shape are provided inside the intake cylinder 20. The upper end of the gas pipe 26 passes through the inside of the gas monitor body 19 and is communicated with the point spraying holes 27.

[0034] The transmission device includes a second bevel gear 10, a second rotating shaft 11, a third rotating shaft 17, a gear 18, a reverse prevention component for connecting the second rotating shaft 11 and the third rotating shaft 17, and a limit component for restricting 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. The right end of the third rotating shaft 17 is fixedly connected to the gear 18.

[0035] In this embodiment, under windy conditions, through the cooperation of the rotating device and the transmission device, the gear 18 drives the rotating ring 21 to rotate, and the rotating ring 21 drives the arc-shaped inclined scraping strip 22 to rotate inside the air inlet cylinder 20. During the rotation of the arc-shaped inclined scraping strip 22, the dust or dirt on the inner wall of the air inlet cylinder 20 is scraped off. And during each rotation of each arc-shaped inclined scraping strip 22, the pressure switch 30 is pressed once. The air pump 25 is started through the pressure switch 30, and nitrogen in the gas tank 24 is ejected from the point injection holes 27 through the air pipe 26 to achieve point injection. By means of point-injecting nitrogen, the dust on the monitoring mirror 28 and the inner wall at the rear end of the air inlet cylinder is blown off and ejected outward by the continuous impact force of the air flow. At the same time, the wind plate 41 on the arc-shaped inclined scraping strip 22 also generates an air flow during rotation. This air flow blows out the mixed dust scraped off by the arc-shaped inclined scraping strip 22 and blown off by the nitrogen from the air inlet cylinder 20 to prevent dust backflow. At the same time, during the rotation of the arc-shaped inclined scraping strip 22, under the action of centrifugal force, it will stick closer and closer to the inner wall of the air inlet cylinder 20 as the rotation speed increases, improving the dust cleaning effect. Due to the unique inclined surface design of the arc-shaped inclined scraping strip 22, larger dirt will be pushed along the inclined surface of the arc-shaped inclined scraping strip 22 to the edge of the inner wall of the air inlet cylinder 20 and discharged after being scraped off. And when the wind blows from the outside to the inside of the air inlet cylinder 20, when the external air flow contacts the outer inclined surface of the conical sleeve 37, a high-speed air flow will be formed, while the air flow velocity along the inner wall is lower than the high-speed air flow on the inclined surface. Thus, an air pressure difference is formed inside and outside, causing the air flow to be discharged outward through the dust discharge hole 44, so that even in the weather when the wind blows from the outside to the inside of the air inlet cylinder 20, the internal dust can still be sucked out through the dust discharge hole 44, thereby achieving dust cleaning.

The side surface of the first bevel gear 9 is meshed and connected to the second bevel gear 10.

[0039] 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 lower surface of the second rotating shaft 11 is rotatably connected to the second fixing bracket 35. The side surface of the third rotating shaft 17 is rotatably connected to the second fixing bracket 35;

[0040] The transmission device includes a second bevel gear 10, a second rotating shaft 11, a third rotating shaft 17, a gear 18, a reverse prevention component for connecting the second rotating shaft 11 and the third rotating shaft 17, and a limit component for restricting 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. The right end of the third rotating shaft 17 is fixedly connected to the gear 18. The reverse prevention component includes a ratchet wheel 12, an outer wheel 13, a positioning column 14, a pawl 15, a spring piece 16, and an adjustment mechanism. The inside of the ratchet wheel 12 is rotatably connected to a positioning shaft 38. The right end of the positioning shaft 38 is fixedly connected to the outer wheel 13. The left inner wall of the outer wheel 13 is fixedly connected to the positioning column 14. The side surface of the positioning column 14 is rotatably connected to the pawl 15. The side surface of the spring piece 16 contacts the pawl 15. The right end of the second rotating shaft 11 is fixedly connected to the ratchet wheel 12. The left end of the third rotating shaft 17 is fixedly connected to the outer wheel 13. The adjustment mechanism includes an adjustment bolt 42 and a limit nut 43. The side surface of the adjustment bolt 42 is threadedly connected to the outer wheel 13. The lower end of the adjustment bolt 42 is rotatably connected to the spring piece 16. The side surface of the adjustment bolt 42 is threadedly connected to the limit nut 43. The limit component includes a first fixing bracket 31, a torsion spring 32, a second pawl 33, and anti-reverse teeth 34 annularly distributed on the side surface of the third rotating shaft 17. The upper surface of the gas monitor body 19 is fixedly connected to the first fixing bracket 31. The side surface of the third rotating shaft 17 is rotatably connected to the first fixing bracket 31. The inside of the first fixing bracket 31 is rotatably connected to the second pawl 33. One end of the torsion spring 32 is fixedly connected to the second pawl 33. The other end of the torsion spring 32 is fixedly connected to the first fixing bracket 31.

[0041] In this embodiment, the motor 3 drives the screw rod 2 to rotate and pushes the mounting frame 1 to lift along the vertical direction of the guiding slide column 36, realizing the lifting of the equipment. This not only facilitates maintenance, but also raises the height of the warning light 39, enabling the warning light 39 to be observed by a larger number of people in the lit state, achieving the effect of warning. Moreover, the wind drives the wind wheel 6 to rotate, so that the first rotating shaft 8 and the first bevel gear 9 on the wind wheel 6 are transmitted to the second bevel gear 10. The second bevel gear 10 drives the second rotating shaft 11 to rotate, and the second rotating shaft 11 drives the ratchet wheel 12 to rotate. When the ratchet wheel 12 rotates forward, the ratchet wheel 12 is caught in the pawl 15. Under the action of the pawl 15, the outer wheel 13 drives the gear 18 on the third rotating shaft 17 to rotate forward. When the wind wheel 6 is affected by reverse wind and the ratchet wheel 12 rotates reversely, the pawl 15 is squeezed by the ratchet wheel 12 and rotates with the positioning column 14, disengaging from the engagement with the ratchet wheel 12, causing the ratchet wheel 12 to rotate idly within the outer wheel 13. And when the ratchet wheel 12 is rotating idly, since it will gently push the elastic piece 16, the outer wheel 13 will have a slight rotation to a certain extent, so that the third rotating shaft 17 rotates reversely. During the reverse rotation of the third rotating shaft 17, the second pawl 33 will be caught in the anti-reverse teeth 34 on the third rotating shaft 17, making it unable to rotate reversely, thus ensuring that even if the wind wheel 6 rotates reversely, the gear 18 will not rotate reversely, achieving the advantage that the gear 18 will only rotate in one direction regardless of the wind direction. At the same time, when the elastic force of the elastic piece 16 is insufficient after long-term use, the elastic piece 16 can be adjusted to be pulled up or pressed down by rotating the adjusting bolt 42, thereby adjusting the pressure of the elastic piece 16 on the pawl 15 to make it fit the pawl 15 again, and then tightening the limit nut 43 to prevent loosening when the outer wheel 13 rotates, further improving the durability of the equipment.
