Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an ecological environment monitoring device. Background Art

[0002] Ecological environmental monitoring refers to the monitoring and analysis of ecological environmental pollution in order to achieve the purpose of real-time monitoring of the ecological environment.

[0003] The current ecological environment monitoring includes air quality monitoring. During the air quality monitoring work, an air quality environment monitoring station will be set up in the wild. The air quality is monitored by the monitoring sensors installed on the air quality environment monitoring station. In order to meet the detection needs of air at different vertical degrees, the current air monitoring station adopts a liftable structure to adjust the height of the monitoring sensor. For example, the patent with patent publication number CN117433574A proposes a real-time monitoring device for the ecological environment.

[0004] The adjustment of the height of the monitoring station mentioned in the above patent is achieved through the active operation of the staff. It should mainly be used for monitoring work that requires a certain height. For ordinary inspection work, when the monitoring station needs to monitor the air quality at different heights, the monitoring height of the monitoring station is often adjusted in a uniform manner, and a fixed maximum monitoring height is reached. In the actual monitoring process, the temperature and humidity of the environment will affect the volatilization and diffusion of pollutants. High temperature accelerates molecular motion, increases the kinetic energy of pollutant molecules, and makes it easier to evaporate from the pollution source. Low humidity will reduce the air saturation, thereby reducing the air's absorption of pollutants, making the pollutant diffusion effect strong. At this time, the pollutants will volatilize and diffuse to a higher height. At this time, the height that needs to be monitored should also be increased accordingly. On the contrary, under the condition of low temperature and high humidity, the diffusion degree of pollutants is low, and the accumulation height is relatively low. At this time, if the monitoring is still carried out at a higher height, it will not only affect the monitoring efficiency and accuracy, but also increase additional energy waste.

[0005] When the wind speed is high, pollutants will be blown away, thereby reducing their concentration. At this time, if a fixed speed is used to adjust the height of the monitoring station, inaccurate monitoring results may occur due to the short relative height residence time. On the contrary, when the wind speed is low, pollutants are relatively concentrated and easy to monitor. At this time, the use of a uniform height adjustment method will affect the monitoring efficiency. The monitoring height and height adjustment speed of the monitoring station cannot be adaptively adjusted according to actual needs, affecting the efficiency and quality of air monitoring.

[0042] The operating principle of the present invention is described as follows: the air monitoring sensor 13 is used to monitor the air quality in real time, and during the monitoring process, the motor rotating assembly 25 is started by the PLC controller 16, and the motor rotating assembly 25 drives the rotating screw 22 to rotate. Through the threaded sleeve effect of the rotating screw 22 and the lifting plate 23, the lifting plate 23 cooperates with the lifting rod 24 to drive the distribution box 10 and the air monitoring sensor 13 to move up and down, thereby realizing the quality monitoring of the air at different vertical heights, and when the motor rotating assembly 25 is in motion, the PLC controller 16 synchronously drives the servo The motor 63 is in motion, and the servo motor 63 drives the adjusting screw 62 to rotate, and the movable plate 64 is driven to move by the threaded sleeve effect of the adjusting screw 62 and the movable plate 64. The working stroke of the entire monitoring height adjustment mechanism 2 is equal to the full stroke of the monitoring height stroke control mechanism 6, that is, when the monitoring height adjustment mechanism 2 reaches the top or the bottom, the movable plate 64 is also located at the outermost side of the control shell 61. When the movable plate 64 presses on the reverse control switch 610 on the side, the PLC controller 16 controls the motor rotating assembly 25 to rotate in the opposite direction, so as to achieve the reciprocating height adjustment work;

[0043] The temperature conductive contact 47 and the temperature resistance rod 48 and the humidity conductive contact 57 and the humidity resistance rod 58 are all connected in series to the power supply circuit of the thrust electromagnetic plate 69. When the external environment temperature rises, the resistance value of the temperature-sensitive resistor 14 is relatively reduced. The temperature-sensitive resistor 14 is a semiconductor resistance rod. When the temperature rises, the number of carriers (electrons or holes) inside the semiconductor increases, resulting in a decrease in resistance value. The temperature-sensitive resistor 14 is connected in series to the power supply circuit of the temperature electromagnetic plate 46. Therefore, when the temperature rises, the resistance value of the temperature-sensitive resistor 14 decreases, so that the power supply current of the temperature electromagnetic plate 46 increases, the magnetism of the temperature electromagnetic plate 46 is enhanced, and the temperature electromagnetic plate 46 is energized to generate the same magnetism as the temperature permanent magnet plate 45. The temperature electromagnetic plate 46 generates a thrust on the temperature permanent magnet plate 45, thereby causing the temperature electromagnetic plate 46 cooperates with the temperature permanent magnet plate 45 to drive the sliding plate 43 to move a longer distance along the fixed slide rod 42 to overcome the elastic force of the reset spring 44, thereby making the sliding distance of the temperature conductive contact 47 on the temperature resistor rod 48 longer, so that the access resistance of the temperature resistor rod 48 increases, thereby reducing the power supply current of the thrust electromagnetic plate 69, making the displacement plate 66 move a shorter distance along the positioning slide rod 65 to overcome the thrust spring 67, so that the displacement plate 66 is located at a more rearward position, so that the moving plate 64 needs to move for a longer time before acting on the reversing control switch 610, thereby increasing the relative monitoring height of the air monitoring sensor 13, meeting the requirement of increasing the kinetic energy of the pollutant molecules under high temperature conditions, making it easier for them to evaporate from the pollution source, and thereby requiring a higher monitoring height;

[0044] When the outside humidity becomes low, the resistance of the humidity-sensitive ceramic 15 increases, and the humidity-sensitive ceramic 15 is connected in series to the power supply circuit of the humidity electromagnetic plate 56, so that the magnetic force of the humidity electromagnetic plate 56 is weakened. Because the humidity electromagnetic plate 56 generates the same magnetism as the humidity permanent magnet plate 55 when it is energized, the humidity electromagnetic plate 56 generates a thrust on the humidity permanent magnet plate 55, thereby causing the force-bearing plate 53 to slide relatively along the guide slide bar 52. When the resistance of the humidity-sensitive ceramic 15 increases and causes the magnetic force of the humidity electromagnetic plate 56 to weaken, the relative movement distance of the force-bearing plate 53 is also smaller, thereby causing the humidity conductive contact 57 to move on the humidity resistance rod 58. The distance is also small, so that the access resistance of the humidity resistance rod 58 is relatively large, and the feedback to the thrust electromagnetic plate 69 is also to make the magnetism of the thrust electromagnetic plate 69 weaker. The displacement plate 66 is located at the rear side of the control shell 61, which can increase the relative height of air monitoring, meet the low humidity will reduce the air saturation, thereby reducing the air absorption of pollutants, which is conducive to the diffusion of pollutants, and thus need a higher monitoring height. The height travel of air monitoring can be adjusted based on the temperature and humidity of the environment, so that the monitoring range is more accurate, the monitoring efficiency is improved, and unnecessary monitoring energy waste is avoided;

[0045] The PLC controller 16 controls the deceleration rotating motor 73 to drive the rotating shaft 72 and the lifting and pressing protrusion 74 to move slowly in the trigger shell 71. When the lifting and pressing protrusion 74 acts on the lifting and pressing trigger switch 75, the PLC controller 16 synchronously controls the motor rotating component 25 and the servo motor 63 to operate for 3 minutes, so that the air monitoring sensor 13 is adjusted to the next height position for air monitoring. The wind speed wheel 82 senses the size of the ambient wind speed in real time. The greater the ambient wind speed, the faster the speed of the wind speed wheel 82, and thus drives the encoder 83 The faster the input end of the encoder 83 rotates, the encoder 83 feeds back data to the PLC controller 16, and the PLC controller 16 controls the deceleration rotating motor 73 to rotate at a lower power when the wind speed is large. Action, thereby shortening the interval time of each height adjustment of the air monitoring sensor 13. Conversely, when the wind speed is low, the deceleration rotating motor 73 is controlled to act at a higher power, and the adjustment rate of the air quality monitoring height can be synchronously feedback-adjusted based on the size of the ambient wind speed, so as to meet the requirement of reducing the height adjustment rate when the wind speed is high, thereby making the relative height air quality monitoring time longer, being able to more accurately capture the changes in pollutant concentration, improve the accuracy of data, obtain more representative data, and avoid the problem that the pollutant concentration is low when the wind speed is high, and the faster monitoring speed cannot accurately monitor and judge the air quality. At the same time, when the wind speed is low, the rate of monitoring height adjustment can be increased, thereby improving the monitoring efficiency;

[0046] After the lifting trigger switch 75 is pressed and triggered, the wiper cleaning mechanism 3 is started synchronously. The PLC controller 16 first controls the distribution box 10 to supply power to the squeezing and pushing electromagnetic plate 315. The squeezing and pushing electromagnetic plate 315 is energized to generate magnetism and cooperate with the squeezing and pushing permanent magnet plate 314 to drive the buffer tube 38 to slide along the anti-slip rod 311, so that the bristle layer 310 contacts the outer wall of the corresponding detection port of the air monitoring sensor 13, and synchronously starts the bidirectional motor drive component 34 and the suction pump 318 to work. The bidirectional motor drive component 34 drives the two reciprocating screws 32 to rotate synchronously, and the threaded sleeve action of the reciprocating screw 32 and the reciprocating plate 33 drives the fixing ring 36 to move up and down outside the air monitoring sensor 13. First, the wiper ring plate 37 removes the water stains outside the air monitoring sensor 13. The dirt is scraped off, and the bristle layer 310 scrapes off the dirt hidden in the detection port corresponding to the air monitoring sensor 13, and the suction pump 318 cooperates with the suction tube 319 to form a negative pressure suction force in the annular hollow cavity 316, and then cooperates with the telescopic hose 317 to form negative pressure suction into the through tube and the suction head 39, so that the suction head 39 can suck away the dirt in the corresponding monitoring port of the air monitoring sensor 13, and the dirt enters the filter assembly 31 and is intercepted by the filter mesh plate therein, and the air monitoring sensor 13 is cleaned synchronously and efficiently, avoiding the problem of dirt adhesion affecting the detection quality of the air monitoring sensor 13, and at the same time avoiding the problem of impurities accumulated in the air monitoring at the previous height affecting the accuracy of the air quality monitoring at the lower height;

[0047] When the humidity in the external environment is high, the resistance of the humidity-sensitive ceramic 15 is small, so that the force-bearing plate 53 can slide a larger distance along the guide slide rod 52, so that the power supply conductive block 59 and the power supply electrical connection strip 510 are in contact, connecting the power supply circuit of the reduction drive motor 93. High ambient humidity is a triggering prerequisite, indicating that the humidity and moisture in the current environment will condense into water droplets outside the air monitoring sensor 13. At the same time, the humidity conductive contact 57 and the humidity resistor rod 58 are also connected in series with the temperature conductive contact 47 and the temperature resistor rod 48 in the power supply circuit of the reduction drive motor 93. When the ambient temperature is low, the moving distance of the sliding plate 43 is small, which makes the access resistance of the temperature resistor rod 48 smaller. When the ambient humidity is high, the sliding distance of the force-bearing plate 53 is large, which makes the access resistance of the humidity resistor rod 58 small. All of these will increase the power supply current of the reduction drive motor 93, and then increase the working power of the reduction drive motor 93, which can shorten the time that the wiper pressing protrusion 94 acts on the wiper trigger switch 95. When the wiper trigger switch 95 is pressed and triggered, the PLC controller 16 controls the bidirectional motor drive component 34 to drive the fixed ring 36 to move up and down, but does not control the distribution box 10 to supply power to the pushing electromagnetic plate 315, so that only the wiper ring plate 37 in the fixed ring 36 acts on the outside of the air monitoring sensor 13 to perform a wiping operation, and can automatically scrape off the condensed water on the surface of the air monitoring sensor 13 based on the changes in the temperature and humidity of the environment, so as to avoid the problem that low temperature and high humidity make it easy for condensed water to accumulate on the surface of the air monitoring sensor 13, thereby affecting the sensitivity and accuracy of the sensor, thereby improving the monitoring quality.
