Description

Technical Field

[0001] This invention relates to the field of outdoor environmental monitoring and processing technology, specifically to an outdoor environmental monitoring device and its monitoring method. Background Technology

[0002] Traditional devices cannot achieve uniform charging. The uneven distribution of the electric field generated by the discharge device causes the droplets to acquire an inconsistent degree of charge when passing through the electric field, affecting the transport effect. Furthermore, the chaotic distribution of positive and negative ions generated by corona discharge makes it easy for positive ions to collide with charged droplets, leading to charge decay and reducing the uniformity and stability of droplet charging.

[0003] The lack of directional guidance means makes droplets susceptible to interference from external airflow during transportation, resulting in disordered diffusion and difficulty in accurately reaching the target location. This reduces the utilization efficiency of the droplets and fails to meet the needs of applications such as targeted spraying and precision coating. Summary of the Invention

[0004] The purpose of this invention is to provide an outdoor environmental monitoring device and its monitoring method to solve the problems of uneven droplet charge and low delivery efficiency in the prior art, which cannot meet the requirements of targeted spraying and precise coating.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an outdoor environmental monitoring device, including a directional atomizing device G, comprising a housing, wherein a fan is fixed to the outer wall of the housing, and an atomizing nozzle, a corona needle, and a magnetic pole with opposite ends are provided inside the housing;

[0006] The fan inputs high-pressure airflow into the housing, the corona needle discharges to form a strong electric field within the housing, the magnetic pole assembly forms a directional guiding force within the housing, and the droplet clusters output by the atomizing nozzle achieve uniform charging through the strong electric field, and are directionally transported under the action of the directional guiding force of the magnetic pole assembly, the thrust of the fan, and the electric field force.

[0007] Furthermore, the housing is provided with a converging flow channel and a expanding flow channel communicating with the output end of the fan. The outer wall of the housing near the output end of the fan is provided with a through hole, and the outer wall of the housing away from the output end of the fan is provided with a droplet spray outlet.

[0008] The converging flow channel, the expanding flow channel, and the droplet outlet are all located on the extension line of the output airflow axis of the fan.

[0009] Furthermore, both the tapered flow channel and the expanding flow channel are configured as tapered tubes.

[0010] Furthermore, a liquid storage tank is provided on the outer wall of the outer shell, and a liquid supply pump is provided at the output end of the liquid storage tank. The liquid supply pump is connected to the atomizing nozzle through a connecting pipe.

[0011] Furthermore, the corona needle is fixed to the side wall of the outer casing by a connecting rod and a fastening screw;

[0012] The fastening screw extends through the housing;

[0013] A shielding plate is provided on the outside of the corona needle.

[0014] Furthermore, the outer casing is provided with a through hole adapted to the fastening screw, and the outer wall of the fastening screw is provided with a fastening nut adapted to the fastening screw.

[0015] Furthermore, the opposite magnetic pole is disposed on the inner wall of the outer shell via a slider and a slide rail;

[0016] The slide rail is fixedly installed on the housing, and the slider is slidably disposed on the slide rail;

[0017] The opposite magnetic pole is fixed to the slider.

[0018] Furthermore, the slider is provided with fastening bolts, and threaded holes that point to the slide rail and are adapted to the fastening bolts are provided on both sides of the slider; a gasket is provided between the opposite magnetic pole and the slider; the number of opposite magnetic poles is at least 4, and they are symmetrically distributed in pairs inside the outer shell.

[0019] An outdoor environmental monitoring method includes the following steps: S1, collecting outdoor environmental parameters in real time through multiple environmental sensors distributed in the monitoring area, the environmental parameters including air humidity, temperature, wind speed, wind direction and particulate matter concentration;

[0020] S2. The collected environmental parameters are wirelessly transmitted to the central controller. The central controller preprocesses and stores the received data and compares and analyzes it with the preset environmental quality threshold.

[0021] S3. When the central controller determines that the current area's air humidity is lower than the preset lower humidity threshold and the wind speed is within the preset operable wind speed range, it generates a first-level warning signal and records the trigger location.

[0022] S4. Based on the trigger location and real-time wind direction data, the central controller calculates and determines the target area and intensity of the atomization operation to be performed.

[0023] S5. The central controller sends a start command to the directional atomizing device G located in the target area or on the upwind side, controlling it to directionally deliver charged droplets to the target area for humidification.

[0024] S6. During the atomization operation, receive real-time feedback environmental data from the monitoring area, dynamically adjust the operating parameters of the directional atomization device G until the air humidity in the monitoring area rises back to the preset normal range, stop the atomization operation and generate an operation report.

[0025] Furthermore, the environmental quality threshold in step S2 includes a first warning threshold and a second warning threshold. When the concentration of particulate matter is detected to exceed the preset second warning threshold, the central controller generates a second-level warning signal and controls the directional atomizing device G to output a droplet size adapted to capture particulate matter in step S5, so that the charged droplets combine with particulate matter in the air and settle during the directional transport process, thereby achieving the synergistic operation of air purification and humidification.

[0026] Compared with the prior art, the present invention, based on the arrangement of the shell, the tapering flow channel and the expanding flow channel, can constrain the flow field of droplet movement, avoid non-target drift, and at the same time provide a closed environment for the formation of electric field and magnetic field, ensuring the charging and directional delivery effect.

[0027] By employing atomizing components, discharge components, and magnetic pole components, and based on the synergistic effect of "electric force + magnetic force + airflow thrust", uniform charging and stable directional transport of droplets are achieved, overcoming the shortcomings of uneven charging and poor targetability in existing technologies, and improving droplet utilization and operational accuracy.

[0037] As attached Figure 1 To be continued Figure 5 As shown:

[0038] Example 1:

[0039] The present invention provides an outdoor environmental monitoring device, including a directional atomizing device G, comprising an air supply component 100, an atomizing component 200, a discharge component 300, and a magnetic pole component 400;

[0040] Among them, the air supply component 100 is used to provide stable airflow power, the atomizing component 200 is used to atomize the liquid into a uniform group of droplets, the discharge component 300 is used to generate corona discharge phenomenon, ionize the surrounding air to form a strong electric field, and the magnetic pole component 400 is used to provide directional guiding force for charged droplets.

[0041] Regarding the air supply assembly 100, which is used as a load-bearing component and power unit, it includes,

[0042] The outer casing 105 serves as a carrier, and the atomizing assembly 200, the discharge assembly 300, and the magnetic pole assembly 400 are all mounted on the outer casing 105;

[0043] The fan can be installed on one side of the housing 105 and fixed to the outer wall of the housing 105. An air outlet is opened on the housing 105 and its output end is adapted to the housing 105.

[0044] Specifically, the fans are axial flow, cross flow, or centrifugal fans, which can be flexibly adjusted by the staff according to process requirements and costs. The air volume adjustment range is 100~500³ / h, and the air pressure adjustment range is 500~2000Pa.

[0045] The tapered flow channel 102 is fixedly installed on the inner wall of the outer casing 105;

[0046] Specifically, the tapered flow channel 102 is located on the inner wall of the outer casing 105 near the fan. The outer casing 105 is provided with through holes corresponding to the fan and the tapered flow channel 102. The diameter of the tapered flow channel 102 at the end that fits into the outer casing 105 is larger than the diameter at the end that is away from the outer casing 105, and it is set in the form of a tapered tube.

[0047] The gradually expanding flow channel 103 is fixedly installed on the inner wall of the outer casing 105;

[0048] Specifically, the axis of the expanding channel 103 is collinear with the extended axis of the contracting channel 102, and is installed on the inner wall of the housing 105 away from the expanding channel 103. The expanding channel 103 is configured as two tapered tubes spliced ​​together. For ease of description, the end closer to the contracting channel 102 is end a, the end away from the contracting channel 102 is end b, and the pipe between end a and end b is end c. The diameter of end a is larger than the diameter of the contracting channel 102 away from the fan end, the diameter of end c is smaller than the diameter of the contracting channel 102 away from the fan end, and the diameter of end b is larger than the diameter of the contracting channel 102 closer to the fan end.

[0049] The droplet outlet 104 is disposed through the side wall of the housing 105 that fits against the gradually expanding flow channel 103;

[0050] During use, the outer shell 105 constrains the droplet flow field to prevent disorderly diffusion of droplets. The fan delivers air, which is pressurized and accelerated through the converging flow channel 102 and the expanding flow channel 103 before being discharged from the droplet outlet 104. The design of the converging flow channel 102 and the expanding flow channel 103 provides stable airflow power. That is, the fan output end, the converging flow channel 102, the expanding flow channel 103, and the droplet outlet 104 form a high-pressure air path, which guides and regulates the airflow, so that the airflow is stably output along the preset direction. Together with the magnetic field formed by the magnetic pole component 400, it promotes the directional movement of charged droplets, enhances the stability and targetability of droplet transportation, and ensures the formation of a stable charged and directional transportation space.

[0051] Regarding the atomizing component 200, used to atomize liquid into a uniform group of droplets and deliver it into an air path, it includes,

[0052] The liquid storage tank 201 is disposed on the outer wall of the outer casing 105 and fixed by bolts;

[0053] A liquid supply pump 202 is installed at the output end of the liquid storage tank 201;

[0054] The connecting pipe 203 is located at the output end of the liquid supply pump 202, and its free end is installed through the outer shell 105;

[0055] Atomizing nozzle 204 is disposed at the end of connecting pipe 203 away from liquid supply pump 202;

[0056] The connecting pipe 203 is set as an "L" or "U" shaped pipe, which is determined according to the position of the liquid storage tank 201 on the outer wall of the outer shell 105 and the position of the atomizing nozzle 204.

[0057] The connecting pipe 203 is made of rigid metal and is used to assist in fixing the liquid storage tank 201, the liquid supply pump 202 and the atomizing nozzle 204;

[0058] The atomizing nozzle 204 adopts a pressure atomization structure, which can atomize liquid into a group of droplets;

[0059] The length of the connecting tube 203 extending into the housing 105 can be adjusted according to the position of the atomizing nozzle 204.

[0060] During use, the operator installs the connecting pipe 203 and the atomizing nozzle 204 to the required process position (specifically, the middle area of ​​the magnetic pole assembly 400), injects the required liquid into the liquid storage tank 201, and the liquid supply pump 202 pressurizes the liquid in the liquid storage tank 201 and then transmits it to the atomizing nozzle 204 through the connecting pipe 203. After atomizing into droplets, the liquid is delivered to the air duct.

[0061] Regarding the discharge component 300, it is used to generate a corona discharge phenomenon, ionizing the surrounding air to form a strong electric field, and includes...

[0062] The connecting rod 301 is installed inside the housing 105 by the fastening screw 302;

[0063] The fastening screw 302 is installed through the outer casing 105;

[0064] The outer casing 105 is provided with a through hole that is compatible with the fastening screw 302;

[0065] At least two fastening nuts 302-1 adapted to fastening screws 302 are provided on both sides of the side wall of the housing 105 and on the outside of the fastening screws 302;

[0066] A corona needle 304 is disposed at the end of the connecting rod 301 away from the fastening screw 302;

[0067] Specifically, the corona needle 304 is made of tungsten wire or stainless steel wire and is arranged directly below the magnetic field area formed by the magnetic pole assembly 400 along the axis of the droplet output direction of the atomizing nozzle 204. The voltage adjustment range is 0KV~20KV. The tip of the corona needle 304 generates a corona discharge phenomenon, ionizing the surrounding air into a strong electric field. When the atomized droplets pass through the electric field, they acquire negative charges, thus achieving uniform charging of the droplets.

[0068] That is, the operator can adjust the position of the connecting rod 301 and the corona needle 304 relative to the air duct by adjusting the position of the fastening screw 302 relative to the outer casing 105 and fixing it with the fastening nut 302-1;

[0069] The shielding plate 303 is set on the outside of the corona needle 304 to shield interference, ensure the stability of the discharge of the corona needle 304, and avoid the impact on the droplet charging effect due to uneven electric field distribution.

[0070] When in use, the corona needle 304 discharges, ionizing the air and creating a strong electric field in the air inside the outer casing 105;

[0071] Furthermore, the positive and negative ions generated by corona discharge will exhibit a specific spatial distribution. In this embodiment, the directional magnetic field formed by the opposite magnetic pole 403 is used to actively screen the ions: negatively charged ions are enriched in the droplet movement channel under the action of magnetic field force, while positive ions are constrained and isolated by magnetic field to avoid collision with charged droplets and resulting in charge decay, thereby ensuring that the atomized droplets can efficiently capture negative charges and achieve uniform charging.

[0072] Regarding the magnetic pole assembly 400, it is used to provide directional guidance force for the charged droplets ionized by the discharge assembly 300. Several magnetic pole assemblies 400 are provided, with a minimum of four, symmetrically installed in pairs on two symmetrical inner walls within the housing 105, each with opposite poles. The distance between this location and the air outlet of the tapered flow channel 102 needs to be set according to specific circumstances to ensure it does not affect ion transport. Each magnetic pole assembly 400 includes...

[0073] Slide rail 401 is fixed to the inner wall of housing 105;

[0074] Specifically, the slide rail 401 can be fixed to the inner wall of the housing 105 by bolts, screws, or pins;

[0075] Slider 402 is slidably mounted on slide rail 401;

[0076] Among them, the slide rail 401 is set as a rectangular body with a square cross section, and the slider 402 is set as a geometric body with a concave cross section. The slide rail 401 and the slider 402 are adapted to each other.

[0077] A fastening bolt 402a is provided on the outer side of the slider 402. A threaded hole adapted to the fastening bolt 402a is provided on the slider 402. The fastening bolt 402a is screwed into the threaded hole on the slider 402, and its end can push against the outer side of the slide rail 401, thereby fixing the slider 402 and the slide rail 401.

[0078] Each slider 402 is provided with at least two fastening bolts 402a, which are symmetrically arranged at both ends of the slider 402 along the slide rail 401;

[0079] The opposite magnetic pole 403 is fixed to the outer wall of the slider 402 near the air passage;

[0080] Specifically, the 403 eccentric magnetic pole uses permanent magnet material, and the magnetic field strength can be adjusted by replacing different specifications of magnetic poles or adjusting the magnetic pole spacing, providing directional guiding force for charged droplets;

[0081] More specifically, a shim is provided between the opposite magnetic pole 403 and the slider 402, and the operator can adjust the distance between the two symmetrically arranged opposite magnetic poles 403 by adjusting the number of shims;

[0082] Among them, the magnetic field formed by several magnetic poles is perpendicular to the axis of the air transport direction;

[0083] During use, the staff can adjust the position of several sliders 402 according to the process requirements, thereby adjusting the position of several opposite magnetic poles 403 relative to the air path, and thus providing directional guiding force for charged droplets;

[0084] In a working environment, the operator can set any two symmetrical magnetic poles as N-pole magnetic blocks and S-pole magnetic blocks, with the polarities of the two magnetic blocks arranged in opposite directions, and installed on two symmetrical slide rails 401 respectively.

[0085] In practical applications, this embodiment includes the following steps:

[0086] S1. Based on the requirements of different operating scenarios, determine the droplet delivery distance, target adhesion density, liquid viscosity / surface tension / conductivity / volatility, droplet size, and operating environment parameters (operating environment parameters include ambient wind speed, wind direction, temperature and humidity, and target morphology), select the appropriate magnetic pole specifications and adjust the magnetic pole position and magnetic pole spacing, determine the magnetic field strength, and preset the liquid delivery flow rate of the atomizing nozzle 204 through the liquid supply pump 202 according to the physical and chemical properties of the liquid and atomization requirements.

[0087] S2. Start the fan and adjust the air volume and air pressure output by the fan according to the conveying distance, the specifications of the narrowing channel 102 and the expanding channel 103, so that the high-pressure airflow forms a stable directional air path. At the same time, start the corona needle 304 and the tip of the corona needle 304 performs stable corona discharge to form a strong electric field.

[0088] S3. The atomizing nozzle 204 outputs a uniform group of droplets. After the droplets enter the air path, they acquire negative charges in the strong electric field formed by the corona needle 304, thus completing the uniform charging.

[0089] S4. Under the synchronous action of the directional guiding force of the magnetic field of the magnetic pole component 400, the thrust generated by the wind path, and the electric field force, the charged droplets move along the directional transport direction of the wind path and accurately reach the target area, thus realizing the stable directional transport of charged droplets.

[0090] S5. During operation, the pressure / start / stop of the liquid supply pump 202, the air volume / pressure of the fan, and the voltage of the corona needle 304 can be adjusted in real time according to the operation effect, so as to dynamically optimize the charging effect and directional delivery accuracy, thus making it suitable for different operation scenarios.

[0091] Compared with the prior art, the present invention has the following technical features:

[0092] Based on the configuration of the outer shell 105, the tapered flow channel 102 and the expanding flow channel 103, the flow field of the droplets can be constrained to avoid non-target drift, and at the same time, a closed environment can be provided for the formation of electric and magnetic fields to ensure the charging and directional delivery effect.

[0093] By employing an atomizing component 200, a discharge component 300, and a magnetic pole component 400, and based on the synergistic effect of "electric force + magnetic force + airflow thrust", uniform charging and stable directional transport of droplets are achieved, solving the defects of uneven charging and poor targetability in existing technologies, and improving droplet utilization and operational accuracy.

[0094] Example 2:

[0095] This embodiment is basically the same as the previous embodiment, except that it provides an outdoor environmental monitoring method, including the following steps.

[0096] S1. Outdoor environmental parameters are collected in real time by multiple environmental sensors distributed in the monitoring area. These environmental parameters include air humidity, temperature, wind speed, wind direction, and particulate matter concentration.

[0097] S2. The collected environmental parameters are wirelessly transmitted to the central controller. The central controller preprocesses and stores the received data and compares and analyzes it with the preset environmental quality threshold.

[0098] S3. When the central controller determines that the current area's air humidity is lower than the preset lower humidity threshold and the wind speed is within the preset operable wind speed range, it generates a first-level warning signal and records the trigger location.

[0099] S4. Based on the trigger location and real-time wind direction data, the central controller calculates and determines the target area and intensity of the atomization operation to be performed.

[0100] S5. The central controller sends a start command to the directional atomizing device G located in the target area or on the upwind side, controlling it to directionally deliver charged droplets to the target area for humidification.

[0101] S6. During the atomization operation, receive real-time feedback environmental data from the monitoring area, dynamically adjust the operating parameters of the directional atomization device G until the air humidity in the monitoring area rises back to the preset normal range, stop the atomization operation and generate an operation report.

[0102] It should be noted that the environmental quality threshold in step S2 includes a first warning threshold and a second warning threshold. When the concentration of particulate matter is detected to exceed the preset second warning threshold, the central controller generates a second-level warning signal and controls the directional atomizing device G to output a droplet size adapted to capture particulate matter in step S5, so that the charged droplets combine with particulate matter in the air and settle during the directional delivery process, thereby achieving the synergistic operation of air purification and humidification.

[0103] Outdoor environmental parameters, including air humidity, temperature, wind speed, wind direction, and particulate matter concentration, are collected in real time by multiple environmental sensors distributed throughout the monitoring area. The collected data is then transmitted to a central controller. The central controller preprocesses and stores the received data, comparing it with preset environmental quality thresholds. When the controller determines that the current area's air humidity is below the preset lower humidity threshold and the wind speed is within the preset operational wind speed range, it calculates the target area and intensity of the atomization operation based on the trigger location and real-time wind direction data. It then sends a start command to the directional atomization device G located in the target area or upwind, controlling it to directionally deliver charged droplets to the target area for humidification. During the atomization operation, the controller receives real-time feedback environmental data from the monitoring area and dynamically adjusts the operating parameters of the directional atomization device G. When the detected particulate matter concentration exceeds the preset threshold, the controller controls the directional atomization device G to output droplet sizes adapted to capture particulate matter, allowing the charged droplets to combine with and settle with airborne particulate matter during directional delivery, achieving a synergistic effect of air purification and humidification. The controller stops atomization and generates an operation report once the air humidity in the monitored area returns to the preset normal range.

[0104] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
