Description

Technical Field

[0001] The present application relates to the technical field of environmental monitoring, and in particular to a portable construction site environmental monitoring device and an installation method. Background Art

[0002] With the improvement of environmental protection awareness, environmental monitoring of construction sites has become increasingly important. Environmental problems at construction sites, such as noise, dust and harmful gas emissions, may not only threaten the health of workers, but also have a negative impact on the quality of life of surrounding residents. Therefore, real-time monitoring and management of the construction site environment to ensure compliance with environmental protection standards is an important issue in the current construction industry.

[0003] Traditional environmental monitoring equipment often has some limitations. These devices are usually large and not easy to carry, which makes them difficult to move and deploy on construction sites. In addition, these devices can often only monitor a single or a few environmental parameters, which limits their application in the changing construction site environment.

[0004] Due to the complexity and variability of the construction site environment, there is a need for a device that can flexibly adapt to different monitoring needs, such as an environmental monitoring device for construction sites with publication number CN112843937A, which relates to the field of environmental monitoring technology. The prior art includes a base, and universal wheels are fixedly installed at the four corners of the bottom of the base, a sleeve is fixedly installed on the left side of the top of the base, a sleeve rod is slidably inserted on the top of the sleeve, a rack is fixedly installed on the outside of the sleeve rod, an adjusting screw is provided on the right side of the sleeve, the left end of the adjusting screw passes through the sleeve, a dust detector is fixedly installed on the outside of the top of the sleeve rod, a support plate is fixedly installed on the right side of the top of the base, and a water pipe is fixedly installed on the top right side of the support plate. The above-mentioned environmental monitoring device for construction sites, by setting a rack and a gear, rotates the adjustment handle, so that the adjusting screw drives the gear to rotate on the rack, so that the sleeve rod drives the dust detector to move up and down, so as to achieve the purpose of adjusting the height and make the monitoring more accurate.

[0005] However, the above existing technologies still have some defects when monitoring the construction site environment:

[0006] 1. When the above technology is used for construction site environmental monitoring, the environmental monitoring device is moved in real time at the construction site to monitor the environmental information of the construction site. The environmental monitoring component obtains the environmental information of the current area and adjusts the height and angle of the environmental monitoring component in real time so that the environmental monitoring component can monitor the environmental information of the current area in all directions. However, the actual construction site environment is complex and changeable, and may contain various obstacles and irregular terrain, which may limit the movement and monitoring range of the monitoring device. The environmental monitoring device may encounter obstacles during movement, resulting in monitoring interruption or equipment damage. Due to various obstacles blocking the real-time movement of the environmental monitoring device, there may be blind spots in environmental monitoring, resulting in the failure to monitor environmental information in certain areas in a timely manner.

[0007] 2. When the above technology is used for construction site environmental monitoring, by setting up atomizers and nozzles, when the dust detector detects that the dust content exceeds the standard, the water pump is turned on by operating the control display to spray water on the surrounding environment to reduce the dust content in the air. Sprinkling water will increase the humidity of the air. In industrial processes that need to maintain a dry environment, the increase in humidity may cause product damage or reduced production efficiency. Sprinkling water may cause the ground to become muddy, which not only affects the cleanliness and safety of the working environment, but may also cause damage to equipment and tools. At the same time, in some cases, sprinkling water may cause dust particles to be re-suspended, which may increase the risk of workers inhaling dust.

[0008] Based on this, and according to the above-mentioned viewpoints, there is still room for improvement in the existing technology for monitoring construction site environments. Summary of the invention

[0045] The following is combined with Figures 1 to 9 This application is described in further detail.

[0046] The embodiment of the present application discloses a portable construction site environment monitoring device and an installation method, which captures charged dust particles through charge attraction, wherein the dust particles are collected and then detected and analyzed. At the same time, water vapor in the air is condensed into liquid water droplets, which are collected and then detected and analyzed, thereby providing comprehensive environmental monitoring for the construction site and ensuring that construction management personnel can ensure the environmental safety of the construction site.

[0047] Embodiment 1:

[0048] Reference Figure 1 and Figure 2 A portable construction site environment monitoring device includes a support tube 1. When monitoring the construction site environment, the entire device is placed on the construction site, and the air intake fan 3 arranged in the support tube 1 is started. The air intake fan 3 generates an airflow, and the air is sucked into the support tube 1 from the air intake cover 2 arranged at the upper end of the support tube 1. When the air passes through the dust collection detector 4 arranged in the air intake cover 2, the charged dust particles are captured by the charge attraction effect, and the dust particles therein are collected. The dust particles collected by the dust collection detector 4 are then sent to the dust collection detector 4 for analysis to detect harmful substances in the dust. The liquefaction detector 5 sends the detected humidity data to the data processing unit for analysis.

[0049] After that, the air after dust removal will enter the liquefaction detector 5 arranged in the support tube 1. The liquefaction detector 5 will first heat the air to increase the temperature of the air and increase the water vapor content in the air to a state close to saturation. The heated air then passes through a temperature lower than the dew point temperature of the air. The dew point temperature refers to the temperature at which water vapor in the air begins to condense into liquid water.

[0050] The water vapor in the air will condense into liquid water droplets, which will be collected. The liquefaction detector 5 will send the collected moisture data to the data processing unit for analysis. The data processing unit can be a microprocessor, a data recorder or a computer system. The portable construction site environmental monitoring device can monitor the dust, harmful gases and humidity in the air, provide comprehensive environmental monitoring for the construction site, and ensure the environmental safety of construction management personnel at the construction site.

[0051] During installation: place the support tube 1 on the ground, then install the liquefaction detector 5 in the support tube 1, then install the air intake fan 3 into the support tube 1, install the liquefaction detector 5 in the air intake cover 2, and then connect the air intake cover 2 to the support tube 1.

[0052] Reference Figures 3 to 5 Specifically, the dust detector 4 includes a plurality of air inlet holes 41 on the air inlet hood 2. After the air inlet fan 3 is started, air will enter the air inlet hood 2 from the air inlet holes 41, and then contact the electrostatic ring 42 arranged at the top of the air inlet hood 2. The electrostatic ring 42 is a charged metal ring or electrode, which is used to apply a charge to the passing air particles. The plurality of ventilation slots 421 on the electrostatic ring 42 allow air to circulate, ensuring that the air can flow evenly through the electrostatic ring 42, thereby optimizing the dust collection efficiency and reducing energy consumption. At the same time, the ventilation slots 421 can also reduce the air resistance inside the electrostatic dust collector, thereby reducing the energy consumption of the air inlet fan 3 and improving energy efficiency.

[0053] The ventilation slots 421 can also help control the electric field distribution around the electrostatic ring 42 and prevent the corona discharge phenomenon, that is, the electric charges in the air form corona discharge near the electrostatic ring 42, which may cause energy waste and noise generation.

[0054] The dust collecting funnel 43 arranged in the air inlet hood 2 and located at the lower side of the air inlet hole 41 will collect the particulate dust attracted by the charge of the electrostatic ring 42. The shape design of the dust collecting funnel 43 is conducive to the concentration and collection of the particulate matter. A number of ventilation holes 431 are opened in the dust collecting funnel 43 to allow air to pass through, and the particulate matter is collected in the dust collecting funnel 43. When air enters through the air inlet hole 41 of the air inlet hood 2, the particulate matter in the air will be subject to the charge applied by the electrostatic ring 42. The charged particulate matter is attracted into the dust collecting funnel 43 under the action of the electrostatic field. The ventilation holes 431 in the dust collecting funnel 43 allow the air to continue to flow, while the particulate matter is collected in the dust collecting funnel 43.

[0055] Afterwards, the closed structure at the bottom of the dust collecting funnel 43 will prevent the particles in the air from being blown away by the wind in the dust collecting funnel 43, ensuring that the particles can be effectively deposited at the bottom of the dust collecting funnel 43. The dust collecting pipe 44 arranged at the lower end of the dust collecting funnel 43 will guide the particles deposited at the bottom of the dust collecting funnel 43 into the dust collecting pipe 44. The downward inclined design of the dust collecting pipe 44 helps the particles to flow naturally under the action of gravity, reducing the possibility of particles accumulating in the dust collecting funnel 43. The dust collecting tank 45 arranged after one end of the dust collecting pipe 44 passes through the support tube 1 will collect the particles flowing out of the dust collecting pipe 44, and the dust collecting tank 45 is detachable.

[0056] A plurality of air outlet holes 451 provided at the bottom of the dust collecting tank 45 allow air to pass through, while particulate matter is collected in the dust collecting tank 45. The size and distribution of the air outlet holes 451 will affect the air flow and the collection efficiency of particulate matter. The dust blocking cloth 46 provided at the bottom of the dust collecting tank 45 may be a filter material with tiny pores, which can capture smaller particulate matter and improve the dust collection efficiency.

[0057] The dust collecting tank 45 may include one or more detection instruments for analyzing the collected particulate matter. The dust collecting tank 45 may include one or more detection instruments for analyzing the collected particulate matter. These instruments may include: an optical particle counter: detecting the number and size of the particulate matter through an optical sensor, a mass analyzer: determining the mass of the particulate matter by weighing the particulate matter, a chemical analyzer: detecting the chemical composition of the particulate matter through a chemical reaction, an X-ray fluorescence spectrometer (XRF): used to analyze the heavy metal content in the particulate matter, etc.

[0058] The detection instrument is usually connected to a data processing unit for processing and analyzing the collected data. The data processing unit can be a microprocessor, a data recorder or a computer system. At the same time, the dust collecting tank 45 can accommodate a certain amount of dust samples, and these particles are sampled for subsequent detailed analysis.

[0059] During installation, place the support tube 1 at the predetermined position of the construction site, ensure that the ground is flat and stable to support the weight of the entire device, install the liquefaction detector 5 in the support tube 1, and then install the air intake fan 3 into the support tube 1. The air intake fan 3 is responsible for inhaling air, so ensure that the air intake fan 3 is firmly installed and the air inlet direction of the air intake fan 3 is correct to facilitate air inflow.

[0060] At the same time, an electrostatic ring 42 is installed on the inner top of the air inlet cover 2. The electrostatic ring 42 is used to charge the air particles passing through, so as to facilitate the subsequent dust collection process. Then, a dust collecting funnel 43 is installed in the air inlet cover 2, located at the lower side of the air inlet hole 41. The dust collecting funnel 43 is used to collect the particles attracted by the charge of the electrostatic ring 42. The ventilation holes 431 in the dust collecting funnel 43 are set to ensure smooth air circulation.

[0061] Connect one end of the dust collecting pipe 44 to the lower end of the dust collecting funnel 43 to ensure that the dust collecting pipe 44 can guide the particles deposited at the bottom of the dust collecting funnel 43 into the dust collecting pipe 44, and then connect the air inlet hood 2 to the support tube 1 to ensure that the connection is well sealed to prevent air leakage and affect the accuracy of the monitoring data.

[0062] Continue to refer to Figures 3 to 5 A transmission shaft 47 is rotatably provided at the bottom of the dust collecting funnel 43. When air passes through the dust collecting funnel 43, a portion of the air will pass through the upper part of the dust collecting funnel 43, and the passed airflow will contact with a plurality of fan blades 49 arranged on the transmission shaft 47 and located on the lower side of the dust collecting funnel 43, thereby generating a rotational force to drive the transmission shaft 47 to rotate. A plurality of fan blades 49 located on the upper side of the dust collecting funnel 43 are arranged on the transmission shaft 47, and the lower surface of the scraper 48 contacts with the upper surface of the dust collecting funnel 43. When the transmission shaft 47 rotates, the scraper 48 rotates accordingly, and the scraper 48 will scrape off the particles on the inner wall of the dust collecting funnel 43 to prevent the particles from accumulating on the inner wall of the funnel, and guide the particles on the inner wall of the dust collecting funnel 43 into the dust collecting pipe 44.

[0063] During installation, pass the drive shaft 47 through the center hole at the bottom of the dust collecting funnel 43, ensure that the length and diameter of the drive shaft 47 are suitable for the design of the dust collecting funnel 43, install the fan blades 49 on the drive shaft 47, ensure that the installation position and direction of the fan blades 49 are correct, use appropriate fasteners to fix the fan blades 49 on the drive shaft 47, ensure that the fan blades 49 are firm and will not loosen during rotation, then install the scraper 48 on the drive shaft 47, ensure that the installation position and direction of the scraper 48 are correct, use appropriate fasteners to fix the scraper 48 on the drive shaft 47, ensure that the scraper 48 is firm and will not loosen during rotation, and ensure that the lower surface of the scraper 48 is in contact with the upper surface of the dust collecting funnel 43 so that it can effectively scrape off particles during rotation.

[0064] A detachable dust filter cloth 432 is provided in the dust collecting funnel 43 at the lower end of the scraper 48. When air passes through the dust collecting funnel 43, particulate matter is attracted by the electrostatic ring 42 and deposited on the dust filter cloth 432, and air circulation is allowed. The scraper 48 rotates to scrape particulate matter from the inner wall of the dust collecting funnel 43 and push it onto the dust filter cloth 432. The particulate matter is captured by the dust filter cloth 432, and clean air flows downward through the dust filter cloth 432 and the ventilation holes 431 on the dust collecting funnel 43. The scraper 48 rotates to scrape particulate matter from the inner wall of the dust collecting funnel 43 and push it into the dust collecting pipe 44.

[0065] Reference Figures 6 to 8Specifically, the liquefaction detector 5 includes a heating wire 51 arranged in the support tube 1. The air flowing downward through the ventilation hole 431 on the dust collecting funnel 43 will contact the heating wire 51. When the air passes through the heating wire 51, the water vapor in the air is heated, resulting in an increase in the water vapor content, making it close to a saturated state. A liquefaction tank 52 is provided in the support tube 1 and is located on the lower side of the heating wire 51. The liquefaction tank 52 is filled with coolant. A plurality of condensation tubes 53 are inserted into the liquefaction tank 52 at the upper end of the liquefaction tank 52. The coolant is a special liquid, which usually has a high heat capacity and good thermal conductivity. It is used to absorb and transfer heat to keep the condensation tube 53 at a relatively low temperature.

[0066] The portion of the condenser 53 located in the liquefaction tank 52 is configured as a spiral section 531. The spiral section 531 can increase the surface area of ​​the condenser 53, increase the contact area with the coolant, and improve the cooling effect, thereby improving the condensation efficiency. At the same time, the spiral section 531 of the condenser 53 helps the air to contact the tube wall when flowing in the tube.

[0067] The heated air will enter the condenser 53 from the upper end of the liquefaction tank 52, and the water vapor will condense into liquid water in contact with the spiral tortuous section 531. The condensed liquid water will pass through the condenser 53 and fall into the guide funnel 54 set at the lower end of the liquefaction tank 52, and then pass through the guide funnel 54 and merge into the liquid collecting pipe 55 set at the lower end of the guide funnel 54. At the same time, the airflow will pass through the condenser 53 and merge from the guide funnel 54 into the liquid collecting pipe 55, and then the gas will pass through the liquid collecting pipe 55 to the outside of the support tube 1 and be discharged.

[0068] The collected liquid water will stay in the U-shaped section 551 provided on the collecting pipe 55, and the liquid water will enter the drainage pipe 56 which is provided at the lowest point of the U-shaped section 551 and is connected to the drainage pipe 56. A detachable water quality detector 57 is provided at the lower end of the drainage pipe 56 to analyze the water quality of the discharged liquid water and detect parameters such as pollutants, pH value, and conductivity in the water. The liquefaction detector 5 can effectively monitor the humidity in the air and collect moisture samples through the condensation process, so as to be suitable for environments that require precise control of humidity, such as laboratories, warehouses, data centers, etc., as well as occasions where the construction site environment needs to be monitored.

[0069] During installation, install the heating wire 51 at a predetermined position in the support tube 1 to ensure that the heating wire 51 can evenly heat the air, pass the condenser 53 through the upper end of the liquefaction tank 52 to ensure that the spiral tortuous section 531 of the condenser 53 is located in the liquefaction tank 52, and fill the coolant in the liquefaction tank 52, then install the liquefaction tank 52 in the support tube 1, located at the lower side of the heating wire 51, to ensure that the spiral tortuous section 531 of the condenser 53 is located in the liquefaction tank 52 to increase the condensation efficiency, then install the guide funnel 54 at the lower end of the liquefaction tank 52, install the liquid collecting pipe 55 at the lower end of the guide funnel 54 to ensure that the liquid collecting pipe 55 can collect liquid water, install the drain pipe 56 at the lowest point of the U-shaped section 551 to ensure that the drain pipe 56 can discharge the liquid water, and finally install the water quality detector 57 at the lower end of the drain pipe 56 to ensure that the water quality detector 57 can accurately detect the water quality parameters of the liquid water.

[0070] Continue to refer to Figures 6 to 8 When air enters the collecting tube 55 from the guide funnel 54, the diameter of the collecting tube 55 becomes smaller. According to the principles of fluid mechanics, the flow velocity will increase while the flow rate will remain unchanged. This increase in flow velocity may cause liquid water to be blown out by the airflow, affecting the retention of the sample.

[0071] The diameter of the U-shaped section 551 on the collecting tube 55 is larger than the diameter of other sides on the collecting tube 55. The U-shaped section 551 is designed to provide an area with an enlarged space in the collecting tube 55, so that when air flows through the U-shaped section 551, the space becomes larger while the flow rate remains unchanged, and the air flow rate slows down. This slowdown in flow rate helps to reduce the impact of the airflow on the liquid water and prevent the liquid water from being blown out of the collecting tube 55, thereby ensuring that the sample can be retained.

[0072] The bottom of the support tube 1 is provided with an opening and closing door panel 11 (at Figure 1 As shown in the figure), the water quality detector 57 can be removed by opening the opening and closing door panel 11, and the liquid water sample in the U-shaped section 551 can be collected.

[0073] An appropriate transition section 552 is provided at the junction between the diameter of the U-shaped section 551 and the diameter of other parts of the collecting pipe 55 to avoid turbulence or dead zone.

[0074] As the cooling liquid is continuously condensed, its temperature will continue to rise. In order not to affect the condensation effect, the liquefied liquid tank 52 is symmetrically provided with connecting pipes 58 connected thereto. The cooling liquid is pumped from the connecting pipes 58 on one side into the support tube (1). A heat dissipation pipe 59 is provided above the heating wire 51. After the cooling liquid passes through the heat dissipation pipe 59, it flows back from the connecting pipe 58 on the other side, forming a circulation in the liquefied liquid tank 52. During this process, the plurality of heat spreaders 591 provided in the heat dissipation pipe 59 have good heat conduction characteristics. The heat of the cooling liquid is transferred to the heat spreader 591 through the heat dissipation pipe 59 constructed as a serpentine structure, and then the heat is taken away by the airflow of the air inlet fan 3, thereby reducing the stability of the cooling liquid and ensuring the condensation effect.

[0075] At the same time, the heat removed heats the air, and cooperates with the heating wire 51 to further heat the air to ensure that the water vapor in the air can be fully condensed.

[0076] Both ends of the two connecting tubes 58 respectively penetrate into the support tube 1 and are connected to both ends of the heat dissipation tube 59. The two connecting tubes 58 are provided with arc-shaped handles 581 outside the support tube 1, so that the operator can grasp and move the support tube 1 through the handles 581, which is convenient for installation and disassembly.

[0077] During installation, connect one end of the two connecting pipes 58 to the corresponding positions of the liquefied tank 52 respectively, and ensure that the connection is well sealed to prevent coolant leakage. The other end of the connecting pipe 58 should be connected to the two ends of the heat dissipation pipe 59.

[0078] Reference Fig. 9 An air volume meter 6 is provided in the support tube 1 and is located below the air inlet fan 3. The air volume meter 6 is installed in the support tube 1 and is located below the air inlet fan 3 to ensure that the airflow generated by the air inlet fan 3 can be accurately measured. The air volume meter 6 is used to measure the volume of air flow, usually in cubic meters per hour (m³ / h). It can measure the air flow rate, flow velocity and air volume.

[0079] Comparing the air flow measured by the air volume meter 6 with the amount of dust and liquid water collected can provide a comprehensive assessment of the environmental quality. For example, if the air volume increases and the amount of dust and liquid water decreases, this may indicate that the environmental quality has improved. Conversely, if the air volume decreases and the amount of dust and liquid water increases, this may indicate that the environmental quality has deteriorated.

[0080] The data from the air volume meter 6, the dust detector 4 and the liquefaction detector 5 can be recorded and analyzed to monitor environmental changes and trends. These data can be used for environmental monitoring, health risk assessment and compliance reporting. At the same time, the dust detector 4 collects the concentration of particulate matter in the air, such as dust, smoke and other suspended particles, and the liquefaction detector 5 has a dehumidification effect and has a certain purification effect.
