Description

[0001] The embodiments of the present invention relate to the technical field of environmental dust fall detection equipment, and in particular to a device for automatically monitoring dust fall. Background Art

[0002] Dust monitoring is an indispensable means to study the environmental impact of atmospheric dust. Dust monitoring methods play a decisive role in scientifically and accurately assessing regional dust levels. The standard methods for atmospheric dust monitoring at home and abroad have obvious differences in terms of sample collection, point layout, and target classification. By comparing and discussing the differences between standard methods, the problems existing in dust monitoring are clarified, providing a reference for the in-depth development of subsequent research.

[0003] In the existing automatic dust monitoring equipment, such as the Chinese utility model patent with publication number CN207096021U, a device for monitoring atmospheric dust particles is disclosed, wherein a main unit is provided with a fixing frame, a box body with an opening downward is provided on the fixing frame, a cover plate is provided at the bottom of the box body, a rotating shaft is provided on the cover plate, a membrane changing disk is rotatably provided on the rotating shaft, a membrane changing motor is also provided at the bottom of the cover plate, an angle sensor is provided on the rotating shaft, a plurality of stepped holes for placing filter membranes are provided on the membrane changing disk, a membrane fixing block is provided on the box body, a film pressing sleeve is slidably provided on the cover plate, a PM2.5 cutter, a PM10 cutter and a sampling head are connected to the membrane fixing block in sequence by pipes, and a flow meter and a sampling pump are connected to the bottom of the film pressing sleeve in sequence by pipes; the device is used for monitoring atmospheric dust particles, and due to the use of a filter membrane, the moisture of the filter membrane is not easy to dry in actual use, thereby affecting the stability of the data, and further, because the volume of the container for collecting dust is large, it is easily disturbed during the measurement, which also causes low data accuracy.

[0035] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the present invention without substantially changing the technical content.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, it shows a device for automatically monitoring dust fall provided by an embodiment of the present invention. The collection device includes a collection system, a measurement system, a temperature and humidity control system, and an auxiliary system.

[0038] The collection system includes a collection channel, a water tank 4 is provided on the side of the collection channel, a collection cylinder 5 is provided at the bottom of the collection channel, a heating plate 6 is provided at the bottom of the collection cylinder 5, a spray device 7 is provided on the top of the collection channel, and the side of the collection cylinder 5 corresponds to the measurement system. The collection cylinder 5 is mainly a conical disk structure with an opening diameter slightly larger than the diameter of the collection channel interface.

[0039] This solution utilizes a collection channel to collect dust, and utilizes a spray device to flush the dust that has landed on the inner surface of the collection bucket into the collection device, which not only eliminates interference but also ensures the accuracy of the data. By using the collection cylinder 5 and a heating plate 6 to heat the collection cylinder 5 after collecting the dust, and drying it, the accuracy of monitoring can be improved.

[0040] like Figure 4 As shown, the measuring system includes a measuring chamber 8 with a measuring port 81, a microgravity sensor 82 is provided in the measuring chamber 8, a camera device 9 is provided between the collecting cylinder 5 and the measuring chamber 8, the collecting cylinder 5 is fixed on the collecting cylinder 5 transmission mechanism, and the heating plate 6 is fixed on the heating plate lifting mechanism 10.

[0041] Among them, the transmission mechanism of the collection cylinder 5 includes a collection cylinder lifting mechanism 11 arranged on the opposite side of the measuring chamber 8, the collection cylinder lifting mechanism 11 is fixed on the collection cylinder transverse transmission mechanism 12, the collection cylinder transverse transmission mechanism 12 is arranged on the same side of the collection channel and the measuring chamber 8, and the collection cylinder transverse transmission mechanism 12 is fixed on the extension plate of the bottom plate of the measuring chamber 8. The collection cylinder lifting mechanism 11, the collection cylinder transverse transmission mechanism 12, and the heating plate lifting mechanism 10 all adopt a displacement transmission actuator composed of a screw rod and a slider, which is driven by a motor. According to the design size of the detection device, the strokes of the three displacement transmission actuators are different. They can be fixed by a bracket or by a structure that is integral with the detection device.

[0042] The collection cylinder lifting mechanism 11 and the measuring room 8 door (on the measuring port 81) are installed on the collection cylinder transverse transmission mechanism 12. The collection cylinder transverse transmission mechanism 12 is responsible for the movement of the collection cylinder 5 between the collection position, the photographing position and the measuring position. When the mechanism moves the collection cylinder 5 to the measuring position, the door of the measuring room is closed, and the measuring room 8 is changed from an open space to a closed environment, which is conducive to better stable control of the temperature and humidity of the measuring room 8. A sealing strip is provided at the measuring port 81.

[0043] In the specific structure, the collection channel includes a collection bucket 1, the bottom side of the collection bucket 1 is a straight channel 2, a protective net 3 is provided inside the collection bucket 1, and a rain detection device 13 is provided outside the collection channel. The wide-mouthed funnel-shaped structure is more conducive to collecting dust. The straight channel 2 can mainly connect to the collection cylinder 5 at the bottom. A protective net 3 is installed at the first-level diameter change of the collection channel to prevent fallen objects such as fallen leaves from falling into the collection cylinder 5, thereby preventing the fallen objects from affecting the data. Such a design is conducive to eliminating the interference of air circulation in the channel on dust, and is conducive to expanding the collection area and improving the sampling accuracy.

[0044] like Figure 5 As shown, the spray device 7 includes a spray pipe 71, which is installed on a spray rotating device. The spray rotating device includes a water pipe seat 72. A sealing rotating block 74 for installing a water spray pipe 73 is provided on the water pipe seat 72. A bearing 75 is provided between the water spray pipe 73 and the sealing rotating block 74. A large toothed disc 76 is provided under the bearing 75. A motor 77 is provided next to the collection device. A small toothed disc 78 meshing with the large toothed disc 76 is provided at the driving end of the motor 77. The water spray pipe 73 is connected to a spray pump 22 arranged at the water tank 4.

[0045] like Fig. 9 As shown, a drain hole 16 is provided on the heating plate 6, and the drain hole 16 is connected to a drainage pump 17 through a hose. A regulating chamber water replenishment pump 18 is provided on the side of the drainage pump 17, and the regulating chamber water replenishment pump 18 is connected to a water replenishment valve 19 arranged on the side of the temperature and humidity regulating chamber 14.

[0046] The collection cylinder 5 is placed on a bracket driven by the collection cylinder 5 elevator, and a heating plate 6 is supported at the bottom. The heating plate 6 is heated by a constant temperature PTC, and the temperature is always maintained at about 60°C, and the moisture in the collection cylinder 5 is dried in real time. There is a rain detection device 13 outside the collection device. When rain is detected or the collection cylinder 5 is controlled by the program to leave the collection channel, the heating plate 6 rises and seals the bottom of the collection channel under the drive of the heating plate 6 driving mechanism. The heating plate 6 is provided with a drainage hole 16, which is connected to the drainage pump 17 with a hose, and then led to the outside with a hose.

[0047] The drainage pump 17 is controlled by the auxiliary mechanism through the drainage sensor. It starts when water is detected and stops when there is no water. Its function is to accelerate the drainage speed and avoid the accumulation of rainwater in the collection channel. After the rain detector detects that the rain outside has stopped, the collection cylinder 5 returns to the collection position.

[0048] like Figure 6As shown, the temperature and humidity control system includes a temperature and humidity regulating chamber 14 provided at the rear side of the measuring chamber 8, an air inlet 83 and an exhaust port 84 are provided on the measuring chamber 8, an opening 141 corresponding to the air inlet 83 and the exhaust port 84 is provided on the temperature and humidity regulating chamber 14, a water storage box 142 is provided in the temperature and humidity regulating chamber 14, a heating pipe 143 is provided on the upper side of the water storage box 142, and the heating pipe 143 is close to the opening 141. The temperature and humidity regulating chamber 14 can adjust the internal temperature and humidity environment, and then communicate with the environment in the measuring chamber 8 to form a suitable measuring environment.

[0049] An evaporator 144 is provided between the heating tube 143 and the opening 141 , a liquid level sensor 145 is provided in the water storage box 142 , and a temperature and humidity sensor 146 is provided in the temperature and humidity adjustment chamber 14 .

[0050] like Figure 7 , Figure 8 As shown, a switching chamber 15 connected to its opening 141 is provided above the temperature and humidity regulating chamber 14, and a circulation port 151 is provided on the side of the switching chamber 15, which corresponds to the air inlet 83 and the exhaust port 84 respectively. A valve 152 is provided on the circulation port 151, and the valves 152 on the two circulation ports 151 are set in opposite directions, that is, they are the inlet valve 152 and the external exhaust valve 152 respectively, and the valve 152 is controlled by an electric actuator.

[0051] When the temperature and humidity in the adjusting chamber are unstable, the switching chamber 15 closes the passage to the measuring chamber 8, and opens the internal passage of the switching chamber 15 to form a circulation between the switching chamber 15 and the adjusting chamber. When the temperature and humidity are stable, the internal circulation passage is closed, and the passage to the measuring chamber 8 is opened to form an external circulation, thereby adjusting the measuring chamber 8 to a stable environment that satisfies the measurement.

[0052] The interior of the conditioning chamber is composed of a water storage box, a temperature and humidity sensor, an evaporator 144 of the refrigeration system, a circulation fan, a heater, a liquid level sensor 145 and a humidifying device.

[0053] Furthermore, a partition 153 is provided inside the switching chamber 15 to separate it into two chambers. The circulation port 151 corresponds to the air inlet 83 and the exhaust port 84 respectively. A separately controlled valve 152 is also provided on the partition 153 to connect or isolate the two chambers.

[0054] A condenser 20 is provided at one end of the outer bottom side of the measuring chamber 8. The condenser 20 is arranged near the outer side of the temperature and humidity adjustment chamber 14. A refrigeration compressor 21 and a radiator (not shown) and other temperature adjustment devices are provided on the side of the condenser 20.

[0055] The auxiliary system of this solution includes a controller and a power adapter. The controller mainly includes a device for receiving detection signals from detection sensors, such as a rain detection device 13, a temperature and humidity sensor 146, a liquid level sensor 145, etc., and a control actuator that acts according to set parameters, such as a heating plate lifting mechanism 10, a collection cylinder lifting mechanism 11, a collection cylinder transverse transmission mechanism 12, a water supply pump, etc. In addition, the final step is to calculate the dust fall data within this collection period by measuring the data of the microgravity sensor 82. The specific implementation of the control element in this solution realizes the automatic operation of the monitoring device, reduces the workload of the staff, and improves the degree of automation of the monitoring device.

[0056] The working principle of the present invention is that during the collection period, the collection cylinder 5 is at the bottom of the collection channel, and the dust in the environment naturally falls into the collection channel due to gravity. The water spray device sprays the inner wall of the collection channel regularly to flush the dust into the collection cylinder 5. The heating plate 6 under the collection cylinder 5 is heated to dry the moisture in the sample. When the collection time is over, the elevator of the heating plate 6 is lowered, and the elevator of the collection cylinder 5 is also lowered. The collection cylinder 5 is separated from the collection device, and the door drive device drives the elevator device of the collection cylinder 5 and the collection cylinder 5 to move to the camera position together, and the collection cylinder 5 is photographed. After completion, it enters the measurement room. Under the joint action of the temperature and humidity control system and the auxiliary system, the temperature and humidity of the measurement room are controlled within the working range of the microgravity sensor, and the dried collection cylinder 5 and its dust are balanced. After the balance time is over, the sample is measured. According to the difference between the current value and the initial value, the dust data within this collection cycle is calculated.

[0057] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
