Description

Technical Field

[0001] The present invention belongs to the technical field of environmental monitoring. Specifically, it relates to an air detection sampling vehicle. Background Art

[0002] A Fourier transform infrared spectrometer is an infrared spectrometer developed based on the principle of Fourier transform of interfered infrared light, and is widely used in fields such as pharmaceutical chemistry, geology and minerals, petroleum, coal, environmental protection, customs, gem identification, and criminal investigation identification. The Fourier transform infrared spectrometer emits infrared light to a detection sample, then receives the reflected infrared light carrying the sample information, and obtains the sample detection result after analysis.

[0003] Currently, Fourier transform infrared technology is also used in air detection. By emitting infrared light into the air, the infrared light interacts with pollutants in the air and is transmitted or reflected back, and the reflected infrared light is analyzed to obtain the detection result. However, the detection result obtained by this detection method is the air detection result of the path passed by the infrared light after emission. If the detection shows pollution, it is impossible to determine which section of the air in the path is polluted. Moreover, this detection method can only obtain semi-qualitative detection results, that is, it can obtain whether there is pollution, but cannot obtain accurate pollution data.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solution of the present invention will be described in detail below.

[0022] An embodiment of the present invention provides an air detection sampling vehicle, as Figure 1As shown in the figure, it includes a vehicle body 1, a Fourier transform infrared analysis device, and a sampling drone 3. A carriage 6 is provided on the vehicle body 1. An unmanned aerial vehicle room 4 and a detection room 7 are provided in the carriage 6. The sampling drone 3 is parked in the unmanned aerial vehicle room 4. A hatch 41 is provided at the top of the unmanned aerial vehicle room 4. An unmanned aerial vehicle landing and take-off assembly for assisting the take-off and landing of the sampling drone 3 is provided in the unmanned aerial vehicle room 4. Preferably, a placement rack 44 is further provided in the unmanned aerial vehicle room 4. A wireless charger is provided on the placement rack 44. The placement rack 44 can be used to park the sampling drone 3 and can also charge the sampling drone 3. Among them, the wireless charger adopts an existing structure, and its specific structure and working principle are common knowledge in the art and will not be elaborated here. The sampling drone 3 includes a drone body and an atmospheric sampling assembly. The atmospheric sampling assembly is arranged on the drone body and is used to collect atmospheric pollutants for further detection of pollutants. The drone body adopts an existing structure, specifically including a frame 311 and wings 312. The wings 312 can have 1, 3, 4, 6, or 8 pieces.

[0023] The Fourier transform infrared analysis device is installed in the detection room 7. The Fourier transform infrared analysis device in this embodiment adopts existing equipment. Specifically, the Fourier transform infrared analysis device includes an infrared analysis device body 21 and an infrared transceiver 22. The infrared analysis device body 21 and the infrared transceiver 22 can be integrally arranged or separately arranged. Preferably, they are separately arranged. As Figure 1 shown in the figure, the infrared analysis device body 21 is installed in the detection room 7, and the infrared transceiver 22 is installed on the outer top of the detection room 7, which is convenient for adjusting the installation position and installation height of the infrared transceiver 22 to adjust the direction and height of the infrared light emitted by the infrared transceiver. The infrared analysis device body 21 includes a light source, a light source transceiver room, a detector, a processor, and a power supply. The power supply supplies power to the infrared transceiver 22, the light source, the detector, and the processor. The infrared transceiver 22 is connected to the light source, the infrared transceiver 22 is connected to the detector, and both the light source and the detector are connected to the processor. A beam splitter, a fixed mirror, and a moving mirror are installed in the light source transceiver room.

[0024] The working process of the Fourier transform infrared analysis device is as follows: The incident light emitted by the light source is split into two beams by the beam splitter. One beam of light reaches the moving mirror through transmission, and the other beam of light reaches the fixed mirror through reflection. The two beams of light are reflected by the fixed mirror and the moving mirror respectively and then return to the beam splitter. Since the moving mirror moves in a straight line at a constant speed, therefore, the two beams of light split by the beam splitter will form an optical path difference, thereby forming interference light. The interference light is transmitted to the infrared transceiver, and the infrared transceiver emits it to the detection sample. After the interference light passes through the detection sample, the interference signal carrying the sample information is received by the infrared transceiver and transmitted to the detector. The detector processes the interference signal to obtain an output signal. The processor performs spectral comparison on the output signal to obtain the semi-qualitative and semi-quantitative results of the pollutants, and then compares the semi-qualitative and semi-quantitative results with the atmospheric standard and the new pollutant list. If there are controlled target pollutants, the detection result is prompted to be abnormal.

[0025] For the air detection sampling vehicle in this embodiment, first, the Fourier transform infrared analysis device is used to preliminarily detect the air. If the preliminary detection result is abnormal, the sampling drone 3 is used to fly to the preliminary detection area, and the preliminary detection area is divided into detection points for collecting air pollutants for further detection, so as to obtain accurate detection results for each detection point in the preliminary detection area. Through the preliminary detection by infrared light and the re-detection of the collected pollutants, the positioning of the local polluted area in the preliminary detection area is realized.

[0026] Preferably, there are multiple sampling drones 3. When the preliminary detection result indicates a pollution phenomenon, by designing the distribution of detection points in the preliminary detection area and establishing a corresponding relationship between the detection points and the serial numbers of the sampling drones, that is, arranging multiple sampling drones at equal intervals along the infrared emission direction for sampling, the specific polluted points and accurate detection results for each point can be obtained. Compared with a single sampling drone flying to each detection point in sequence, the detection efficiency is high, and there will be no mixing phenomenon during sampling, improving the detection accuracy.

[0027] As a preferred example, as Figure 3 shown, the air sampling assembly includes a sampling pump 321, a particle trap 322, a first collection tube, an organic pollutant collector 323 and a second collection tube. The first collection tube is connected between the particle trap 322 and the sampling pump 321, and a first valve 324 is provided on the first collection tube. The second collection tube is connected between the organic pollutant collector 323 and the sampling pump 321, and a second valve 325 is provided on the second collection tube. Among them, the sampling pump 321 includes a pump body, an inlet and an outlet are provided on the pump body, a rotating shaft and an impeller are provided in the inner cavity of the pump body, and the impeller is arranged on the rotating shaft. The first collection tube and the second collection tube are both connected to the inlet of the pump body. The particle trap 322 is an existing structure for filtering out particulate matter in the air. The organic pollutant collector 323 is an existing structure, including a housing with openings at both ends, and an adsorbent is provided in the housing for adsorbing organic pollutants in the air.

[0028] During operation, if it is necessary to collect particulate matter and organic pollutants, the first valve 324 and the second valve 325 are opened. The rotating shaft of the sampling pump 321 drives the impeller to rotate, generating a negative pressure in the inner cavity of the pump, causing the atmosphere to enter the particulate matter catcher 322 and the organic pollutant collector 323. The atmosphere entering the particulate matter catcher 322 passes through the particulate matter catcher 322 to intercept and filter the particulate matter, then enters the inner cavity of the pump through the first collection pipe, and finally exits from the outlet of the pump. The atmosphere entering the organic pollutant collector 323 passes through the organic pollutant collector 323 to adsorb the organic pollutants, then enters the inner cavity of the pump through the second collection pipe, and finally exits from the outlet of the pump. Thus, the sampling drone collects the particulate matter and organic pollutants in the atmosphere for further detection. If only particulate matter needs to be collected, the first valve 324 is opened and the second valve 325 is closed. If only organic pollutants need to be collected, the second valve 325 is opened and the first valve 324 is closed.

[0029] In this embodiment, the atmosphere is sucked by the sampling pump, and the atmosphere is discharged after passing through the particulate matter catcher 322 and the organic pollutant collector 323. The particulate matter catcher 322 intercepts the particulate matter in the atmosphere, and the organic pollutant collector 323 adsorbs the organic pollutants in the atmosphere, so as to obtain the particulate matter and organic pollutants in the atmosphere, which can be used for laboratory detection to accurately obtain the particulate matter concentration, the composition of organic pollutants, and the composition percentage of each component. The structure is simple and the collection is convenient. At the same time, according to the preliminary detection results, by controlling the opening and closing of the first valve and the second valve, it is possible to select whether to collect particulate matter or organic pollutants, and sample specifically to meet different requirements.

[0030] Preferably, the number of sampling pumps 321 is the same as the number of wings 312 of the drone body, both are N, and N is an integer greater than or equal to 1. And the sampling pumps 321 are arranged below the wings 312, and the sampling pumps 321 correspond to the wings 312 one by one. In this embodiment, one sampling pump 321 is arranged below each wing 312, that is, the sampled gas is discharged from below the wings, generating an air flow below the drone body.

[0031] More preferably, N is an integer greater than or equal to 2. For example Figure 3As shown, the air sampling assembly also includes a multi-channel electromagnetic valve 326, which includes a connecting shell, which is provided with a first inlet, a second inlet and at least N outlets, the first inlet, the second inlet and the outlet are all connected to the inner cavity of the connecting shell, and all outlets are provided with quantitative valves to make the airflow rate entering all outlets the same. The particle trap 322 is connected to the first inlet of the multi-channel electromagnetic valve 326 through a first collection tube, the organic pollutant collector 323 is connected to the second inlet of the multi-channel electromagnetic valve 326 through a second collection tube, and the N outlets of the multi-channel electromagnetic valve 326 are connected to the inlets of the N sampling pumps 321 through air pipes.

[0032] In this embodiment, the gas sucked in after the particulate matter is filtered by the particle trap 322 and the gas sucked in after the organic pollutant collector 323 adsorbs the organic pollutants is evenly diverted to N collection pumps for discharge through the multi-channel solenoid valve 326, so that the airflow intensity under each wing is the same, thereby making the flow field under the N wings dynamically balanced, ensuring the flight balance of the sampling drone.

[0033] Preferably, the sampling pump 321 is a motorless pump, and the rotating shaft of the sampling pump 321 is connected to the wing 312. In this embodiment, the wing 312 rotates when the drone body is flying, driving the rotating shaft of the sampling pump 321 to rotate, thereby generating suction to suck the atmosphere, realizing energy recovery and reuse, and at the same time, there is no need to set a motor to drive the sampling pump to operate, which reduces the overall weight of the sampling drone, is conducive to balanced flight, and reduces energy consumption.

[0034] As a preferred example, Figure 3 As shown, the drone body is also provided with a laser particle counter 327 and a VOCs gas detector 328, both of which are mounted on a rack 311. The laser particle counter 327 and the VOCs gas detector 328 are both existing equipment. The laser particle counter 327 is used to measure the number and particle size distribution of particulate matter per unit volume in the atmosphere, and the VOCs gas detector 328 is used to detect the concentration of organic pollutants in the atmosphere.

[0035] During operation, the laser particle counter 327 can be used to measure the number of particulate matter particles per unit volume and the particle size distribution in the atmosphere, and the VOCs gas detector 328 can be used to measure the concentration of organic pollutants in the atmosphere. If the number of particulate matter particles detected by the laser particle counter 327 exceeds the first preset value, the sampling pump 321 and the first valve 324 are activated, and the particle trap 322 is used to collect particulate matter for further accurate detection. If the concentration of organic pollutants detected by the VOCs gas detector 328 exceeds the second preset value, the sampling pump 321 and the second valve 325 are activated, and the organic pollutant collector 323 is used to collect organic pollutants for further accurate detection. If the number of particulate matter particles detected by the laser particle counter 327 exceeds the first preset value and the concentration of organic pollutants detected by the VOCs gas detector 328 exceeds the second preset value, the sampling pump 321, the first valve 324 and the second valve 325 are activated, and the particle trap 322 is used to collect particulate matter for further accurate detection, and the organic pollutant collector 323 is used to collect organic pollutants for further accurate detection.

[0036] In this embodiment, the laser particle counter 327 and the VOCs gas detector 328 are used to quickly detect the concentration of particulate matter and the concentration of organic pollutants in the atmosphere at the detection point. If the concentration does not exceed the preset concentration, there is no need to collect samples. If the concentration exceeds the preset concentration, samples are collected according to the pollution situation (whether the concentration of particulate matter is high, the concentration of organic pollutants is high, or both are high) for further accurate detection. Thus, through the detection and sampling of the sampling drones at multiple detection points, the positioning of the polluted local area within the detection area can be achieved, and accurate detection results can be obtained.

[0037] Further preferably, the particle trap 322 and the organic pollutant collector 323 are respectively arranged on the upper and lower sides of the drone body, and the laser particle counter 327 and the VOCs gas detector 328 are respectively arranged on the upper and lower sides of the drone body. And the organic pollutant collector 323 and the laser particle counter 327 are located on the same side. To maintain the balance of the upper and lower sides of the drone body, one detection device and one collection device are arranged on each side, but it is ensured that the VOCs gas detector 328 and the organic pollutant collector 323 are not on the same side. Such an arrangement can avoid the VOCs gas detector 328 from pumping air during the previous detection and affecting the air intake of the organic pollutant collector 323 during subsequent collection, thereby ensuring that the organic pollutant collector 323 can intake enough air during collection and improving the detection accuracy of organic pollutants.

[0038] Preferably, as Figure 2As shown in the figure, the takeoff and landing assembly of the drone includes a lifting rod 421 and a landing gear 422. One end of the lifting rod 421 is fixedly arranged in the drone chamber 4, and the other end of the lifting rod 421 is connected to the landing gear 422. A magnetic adsorption fixator 423 is provided on the landing gear 422. When the sampling drone 3 takes off, the sampling drone 3 is located on the landing gear 422. The lifting rod 421 extends upward to drive the landing gear 422 out of the drone chamber, and the sampling drone 3 starts to fly. When the sampling drone 3 lands, the sampling drone 3 lands on the landing gear 422, and the magnetic adsorption fixator 423 fixes the sampling drone 3. The lifting rod 421 retracts downward to drive the landing gear 422 back into the drone chamber. Preferably, the magnetic adsorption fixator 423 can adopt an electromagnet. When the sampling drone 3 starts to prepare for takeoff, the electromagnet is powered off and does not generate magnetic force, reducing the resistance to the sampling drone. In other cases when the sampling drone 3 is located on the landing gear, the electromagnet is powered on to generate magnetic force, so that the sampling drone is fixed on the landing gear to prevent it from falling.

[0039] As a preferred example, the air quality detection and sampling vehicle of this embodiment further includes an organic pollutant analyzer 5, and the organic pollutant analyzer 5 is installed on the vehicle body 1. As Figure 2 shown in the figure, a heating and sampling assembly is also provided in the drone chamber 4. The heating and sampling assembly includes a heating box body 431. A heater 432 is provided in the heating box body, and the heater 432 is connected to a temperature controller 434. An opening is provided at the top end of the heating box body 431, and a sampling pipe 433 is provided at the bottom end. The sampling pipe 433 is connected to the organic pollutant analyzer 5. After the sampling drone 3 collects organic pollutants, under the action of the locator 424, the sampling drone lands at a preset position on the drone takeoff and landing assembly. The magnetic adsorption fixator 423 fixes the sampling drone 3. The organic pollutant collector 323 of the sampling drone extends into the heating box body 431. The temperature controller 434 controls the heater 432 to heat the organic pollutant collector 323, so that the temperature in the heating box body 431 is maintained at 80 - 130 °C. The organic pollutants in the organic pollutant collector 323 volatilize into gas, enter the organic pollution analyzer 5 through the sampling pipe 433, and the organic pollutant analyzer 5 detects the volatilized gas of the organic pollutants to obtain the composition of the organic pollutants and the percentage of each component.

[0040] The working process of the air quality detection and sampling vehicle of the above preferred embodiment is as follows:

[0041] The air quality detection and sampling vehicle travels to the location to be detected. The Fourier transform infrared analysis device emits infrared light into the high altitude to conduct a preliminary detection of the atmosphere and obtains a preliminary detection result. If the preliminary detection result indicates that there is no pollution phenomenon, the air quality detection and sampling vehicle continues to travel for detection, and the traveling speed during the detection process is less than 25 km / h.

[0042] If the preliminary detection results indicate pollution, the atmospheric detection sampling vehicle stops. The detection point distribution is designed for the preliminary detection area, that is, along the infrared emission direction, detection points are arranged at equal intervals, and a corresponding relationship is formed between the detection points and the serial numbers of the sampling drones.

[0043] One by one, the sampling drone 3 is placed on the landing gear 422, the lifting rod 421 extends upward, driving the landing gear 422 out of the drone chamber 4, and the sampling drone 3 starts and flies to its corresponding detection point. All sampling drones 3 fly to their corresponding detection points.

[0044] When each sampling drone 3 is working, the laser particle counter 327 measures the number of particulate matter particles and the particle size distribution per unit volume in the atmosphere, and the VOCs gas detector 328 measures the concentration of organic pollutants in the atmosphere. If the number of particulate matter particles detected by the laser particle counter 327 exceeds the first preset value, the sampling pump 321 and the first valve 324 are started, and the atmosphere entering the particle trap 322, after the particulate matter is intercepted and filtered by the particle trap 322, enters the inner cavity of the communication housing of the multi-channel solenoid valve 326 through the first collection tube. The air flow evenly flows into the pump body from all outlets in equal amounts and finally discharges from the outlet of the pump body. If the concentration of organic pollutants detected by the VOCs gas detector 328 exceeds the second preset value, the sampling pump 321 and the second valve 325 are started, and the atmosphere entering the organic pollutant collector 323, after the organic pollutants are adsorbed by the organic pollutant collector 323, enters the inner cavity of the communication housing of the multi-channel solenoid valve 326 through the second collection tube. The air flow evenly flows into the pump body from all outlets in equal amounts and finally discharges from the outlet of the pump body. If the number of particulate matter particles detected by the laser particle counter 327 exceeds the first preset value and the concentration of organic pollutants detected by the VOCs gas detector 328 exceeds the second preset value, the sampling pump 321, the first valve 324 and the second valve 325 are started. The atmosphere entering the particle trap 322, after the particulate matter is intercepted and filtered by the particle trap 322, enters the inner cavity of the communication housing of the multi-channel solenoid valve 326 through the first collection tube; the atmosphere entering the organic pollutant collector 323, after the organic pollutants are adsorbed by the organic pollutant collector 323, enters the inner cavity of the communication housing of the multi-channel solenoid valve 326 through the second collection tube; the air flow in the inner cavity of the communication housing evenly flows into the pump body from all outlets in equal amounts and finally discharges from the outlet of the pump body.

[0045] The sampling drones 3 land one by one. Under the action of the locator 424, the sampling drones land at the preset positions on the drone landing assembly. The magnetic fixing device 423 fixes the sampling drones 3. The lifting rod 421 retracts downward to drive the landing gear 422 back into the drone room. The sampling drones 3 that have not performed sampling are directly placed on the rack in the drone room for charging. If the sampling drone only samples particulate matter, the particle trap is removed for detection, and the sampling drone 3 is directly placed on the rack in the drone room for charging. If the sampling drone samples particulate matter and organic pollutants, first the particle trap is removed for detection, and the organic pollutant collector 323 extends into the heating box 431. The temperature controller 434 controls the heater 432 to heat the organic pollutant collector 323, so that the temperature in the heating box 431 is maintained at 80 - 130 °C. The organic pollutants in the organic pollutant collector 323 volatilize into gas, and enter the organic pollution analyzer 5 through the sampling pipe 433. The organic pollution analyzer 5 detects the organic pollutant volatilized gas to obtain the composition of the organic pollutants and the percentage of each component. If the sampling drone only samples organic pollutants, the organic pollutant collector 323 extends into the heating box 431. The temperature controller 434 controls the heater 432 to heat the organic pollutant collector 323, so that the temperature in the heating box 431 is maintained at 80 - 130 °C. The organic pollutants in the organic pollutant collector 323 volatilize into gas, and enter the organic pollution analyzer 5 through the sampling pipe 433. The organic pollution analyzer 5 detects the organic pollutant volatilized gas to obtain the composition of the organic pollutants and the percentage of each component. The detection results of the particle trap and the detection results of the organic pollution analyzer all correspond one by one to the sampling drone serial numbers. Thus, according to the one-to-one correspondence between the sampling drone serial numbers and the detection points, the one-to-one correspondence between the sampling drone serial numbers and the detection results of the particle trap, and the one-to-one correspondence between the sampling drone serial numbers and the detection results of the organic pollution analyzer, the specific positions where pollution exists in the preliminary detection area and the qualitative and quantitative detection results of the pollution are obtained, realizing the positioning of the local area with pollution.
