Abstract
Description
Technical Field
[0001] This utility model relates to the field of atmospheric monitoring equipment technology, specifically to an atmospheric pollutant monitoring device. Background Technology
[0002] In order to monitor the air quality of a certain area in real time and determine whether the pollutants in the air exceed the standards, air monitoring equipment is usually installed at a high position in the area. At the same time, the air sampling equipment is powered on and connected to the network. The air sampling equipment works for a long time to complete the air quality detection and send the detection results to the control center so that environmental monitoring staff can view the air monitoring data.
[0003] A patent for an air pollutant monitoring device, with announcement number CN218914360U, includes a base plate and a fixed rod. The fixed rod is mounted on the upper end of the base plate, and three lifting slots are formed on the side of the fixed rod. A threaded rod is rotatably connected inside the lifting slots. A bevel gear 1 is mounted on the lower part of the outer surface of the threaded rod, meshing with a second bevel gear. A rotating shaft is mounted on one end of the second bevel gear. An annular cover is mounted on the lower part of the outer surface of the fixed rod, and three sliding doors are provided on the side of the annular cover. An extension rod is fitted onto the outer surface of the threaded rod, and the extension rod is threadedly connected to the threaded rod. This invention uses a rotating block to drive the threaded rod to rotate, causing the control box, solar panel, or air monitoring instrument to descend, making it easy for staff to access and disassemble for maintenance or replacement. This is convenient and quick, eliminating the need for staff to climb for disassembly and maintenance, and ensuring high safety.
[0004] However, in this existing technology, because the atmospheric monitoring equipment is exposed to the air for a long time, the humidity in the air is high on cloudy or rainy days. The sampling probe is in a humid environment for a long time, and the sampling probe will be corroded by the moisture in the atmosphere, affecting the service life of the probe. Moreover, it is inconvenient to clean the dust attached to the surface of the sampling probe, which is not conducive to the real-time collection of accurate atmospheric quality data.
[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
[0006] The purpose of this invention is to provide an air pollutant monitoring device that can effectively solve the above-mentioned technical problems.
[0007] To achieve the purpose of this utility model, the following technical solution is adopted:
[0008] An air pollutant monitoring device includes: a monitoring host, a detection probe fixedly installed on the monitoring host, a cleaning assembly for cleaning the surface of the detection probe, and a humidity sensor fixedly installed on the monitoring host;
[0009] The cleaning assembly includes: a bracket fixedly mounted on the monitoring host, a lifting plate movably mounted on the bracket, an electric push rod that lifts and lowers the lifting plate, a motor fixedly mounted on the lifting plate, a cover fixedly mounted on the output end of the motor, brush bristles fixedly mounted on the cover, and a dust blowing assembly disposed on the cover for cleaning dust on the detection probe.
[0010] Furthermore, the brush bristles are provided in multiple sets, and the multiple sets of brush bristles are fixedly installed at equal intervals along the circumference on the inner wall of the lower end of the mask.
[0011] Furthermore, the dust blowing assembly includes: a fixing member fixedly mounted on the cover; a movable member sliding on the fixing member, wherein a blowing member is connected to the fixing member, and one end of the blowing member is fixedly mounted on the cover.
[0012] Furthermore, a spring is fixedly connected to the top of the fixing member, and one end of the spring is fixedly connected to the top of the moving member.
[0013] Furthermore, a ball bearing is installed at the bottom of the moving part, and the bottom of the ball bearing rests on the surface of the monitoring host.
[0014] Furthermore, a sealing plate is fixedly connected to the lower surface of the detection probe, and the diameter of the sealing plate matches the inner diameter of the shield.
[0015] Compared with the prior art, the present invention has the following beneficial effects: When the rainy season arrives, the cleaning component allows the cover to drop and shield the detection probe, reducing the entry of moisture. At the same time, as the cover drops and rotates, the bristles on the inner wall of the cover clean the surface of the detection probe, preventing the detection probe from being exposed to the air for a long time without being cleaned, which would cause a large amount of dust to adhere to its surface and affect the monitoring accuracy. In addition, the dust blowing component blows off the floating dust on the surface of the detection probe after cleaning, thereby further improving the cleaning effect of the detection probe surface.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0024] like Figures 1 to 4 As shown, the atmospheric pollutant monitoring device of this utility model includes: a monitoring host 1, a detection probe 2 fixedly installed on the monitoring host 1, a cleaning assembly 3 for cleaning the surface of the detection probe 2, and a humidity sensor 5 fixedly installed on the monitoring host 1.
[0025] The cleaning assembly 3 includes: a bracket 301 fixedly mounted on the monitoring host 1, a lifting plate 302 movably mounted on the bracket 301, an electric push rod 303 that lifts and lowers the lifting plate 302, a motor 304 fixedly mounted on the lifting plate 302, a cover 305 fixedly mounted on the output end of the motor 304, a brush bristle 3051 fixedly mounted on the cover 305, and a dust blowing assembly 4 disposed on the cover 305 for cleaning dust on the detection probe 2.
[0026] It should be added that the upper end of the bracket 301 is provided with a sliding groove, and the end of the lifting plate 302 is fixedly connected with a slider that cooperates with the sliding groove. The two ends of the lifting plate 302 are slidably installed in the upper sliding groove of the bracket 301 through the slider.
[0027] When the rainy season arrives, and the humidity sensor 5 detects that the humidity in the air has reached the set value, the output end of the electric push rod 303 drives the lifting plate 302 to descend, causing the motor 304 on the lifting plate 302 to drive the shield 305 at the output end to descend, thus shielding the detection probe 2. At the same time, the motor 304 starts, and the motor 304 drives the shield 305 at the output end to rotate. As the lifting plate 302 descends, the brush bristles 3051 on the lower inner wall of the shield 305 descend and rotate at the same time, cleaning the surface of the detection probe 2. This prevents the detection probe 2 from being exposed to the air for a long time without being cleaned, which would cause a large amount of dust to adhere to its surface and affect the accuracy of monitoring.
[0028] As an additional setting, multiple sets of brush bristles 3051 are provided, and these multiple sets of brush bristles 3051 are fixedly installed at equal intervals along the circumference on the inner wall of the lower end of the cover 305. When the cover 305 is rotated by the output end of the motor 304, the cover 305 uses the multiple sets of brush bristles 3051 on the lower inner wall to sweep away the dust on the surface of the detection probe 2, so as to avoid the accumulation of dust on the surface of the detection probe 2 and affect the accuracy of atmospheric pollutant monitoring data acquisition.
[0029] As a further extension of this utility model, since dust will still adhere to the surface of the detection probe 2 after the brush bristles 3051 have swept the surface of the detection probe 2, there will still be dust adhering to the surface of the detection probe 2.
[0030] The dust blowing assembly 4 includes: a fixing member 401 fixedly installed on the cover 305; a moving member 402 sliding on the fixing member 401; a blowing member 403 connected to the fixing member 401, and one end of the blowing member 403 fixedly installed on the cover 305; it should be noted that the fixing member 401 is an air storage cylinder, the moving member 402 is a piston rod, the blowing member 403 is a blowing pipe, and three blowing heads are fixedly connected at equal intervals on the blowing pipe, and the blowing heads are fixedly installed on the cover 305.
[0031] When the electric push rod 303 drives the lifting plate 302 to descend, the cover 305 drives the fixing part 401 to descend, causing the moving part 402 to squeeze the air inside the fixing part 401. The air is blown out through the blowing part 403. At the same time, the motor 304 drives the cover 305 to rotate, so that the blowing part 403 blows off the floating dust on the surface of the detection probe 2 after cleaning by rotating, thereby further improving the cleaning effect of the surface of the detection probe 2.
[0032] It should be added that a spring 404 is fixedly connected to the top of the fixing member 401, and one end of the spring 404 is fixedly connected to the top of the moving member 402; when the cover 305 moves the fixing member 401 upward, the spring 404 inside the fixing member 401 is elastically reset after being stressed, pushing the moving member 402 downward, so that the fixing member 401 is filled with air, which is convenient for the next use.
[0033] It should be noted that the bottom of the movable part 402 is equipped with a ball bearing, and the bottom of the ball bearing rests on the surface of the monitoring host 1. By setting the ball bearing, the contact area between the bottom of the movable part 402 and the surface of the monitoring host 1 is reduced, thereby reducing the friction between the bottom of the movable part 402 and the monitoring host 1 when the cover 305 drives the fixed part 401 to rotate, and improving the rotational stability of the movable part 402.
[0034] It should be added that a sealing plate 201 is fixedly connected to the lower surface of the detection probe 2, and the diameter of the sealing plate 201 matches the inner diameter of the shield 305. After the shield 305 is lowered into place, the sealing plate 201 forms a closed space inside the shield 305, reducing the entry of water vapor, reducing the corrosion of the detection probe 2 by moisture, and improving the service life of the detection probe 2.
[0035] Working principle: When the power is turned on, during the rainy season, when the humidity sensor 5 detects high humidity in the air, the output end of the electric push rod 303 drives the lifting plate 302 to descend, causing the motor 304 on the lifting plate 302 to drive the output end cover 305 to descend, covering the detection probe 2. At the same time, the motor 304 starts, driving the output end cover 305 to rotate. As the lifting plate 302 descends, the brush bristles 3051 on the lower inner wall of the cover 305 descend and rotate, cleaning the surface of the detection probe 2. When the output end of the electric push rod 303 drives the lifting plate 302 to descend, the cover 305 drives the fixing part 401 to descend, causing the moving part 402 to squeeze the air inside the fixing part 401. The air is blown out through the blowing part 403. At the same time, the motor 304 drives the cover 305 to rotate, causing the blowing part 403 to blow off the floating dust on the surface of the detection probe 2 after cleaning by rotating.
