Obviously, the described embodiments are only 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.

[0026] See also Figure 1-5 The present invention provides a technical solution: a mobile air quality remote sensing monitoring device, comprising an unmanned aerial vehicle 1, a lifting adjustment frame, an anti-airflow interference component, a suspended segmented air sampling mechanism and a lifting regulator, the lifting adjustment frame is installed at the bottom of the unmanned aerial vehicle 1, the anti-interference component is installed at the bottom of the lifting adjustment frame, the suspended segmented air sampling mechanism is installed at the bottom of the anti-airflow interference component, the suspended segmented air sampling mechanism is composed of a plurality of samplers 2, the lifting regulator is installed at the bottom of the anti-airflow interference component and is located on one side of the suspended segmented air sampling mechanism, and the lifting regulator is used in conjunction with the suspended segmented air sampling mechanism;

[0027] The anti-airflow interference component includes a chassis 3, an air pump 4 and an extendable airflow shield 5. The chassis 3 is fixed to the bottom of the lifting adjustment frame, the air pump 4 is installed on the top of the chassis 3, the extendable airflow shield 5 is arranged on the top of the chassis 3 and a slot 6 is opened in the middle. The air pump 4 is located in the slot 6 and the air outlet is connected to the extendable airflow shield 5 through a pipeline. When the drone 1 needs to be remotely controlled to the monitoring area, it can be inflated by the air pump 4 and introduced into the extendable airflow shield 5. The extendable airflow shield 5 is extended and opened to block the disturbance of the drone 1 to the airflow below, thereby reducing the impact on the air;

[0028] The sampler 2 includes an air duct 7, an air inlet hood 8, a pump body 9, a magnetic opener and closeer 10, an air duct 11 and an air storage container 12. The right side of the air duct 7 is processed into a slide groove 13, and a slide rod 14 is slidably arranged in the slide groove 13. The slide rod 14 is connected to the adjacent sampler 2. The air inlet hood 8 is installed at the lower left corner of the air duct 7. The pump body 9 is installed at the upper end of the air duct 7 and the air outlet end is connected to the magnetic opener and closeer 10 through a pipeline. The magnetic opener and closeer 10 is connected to the air storage container 12 through the air duct 11. When it is necessary to collect air, the air is extracted through the pump body 9, and the air enters the air duct 7 through the air inlet hood 8 and enters the air storage container 12 along the air duct 11.

[0029] The lifting regulator includes a driving motor 15 and a screw 16 installed at the power output end of the driving motor 15. A floating plate 17 is threadedly inserted into the lower end of the screw 16. One side of the floating plate 17 is connected to the lower end of the sampler 2 located at the bottom. The screw 16 is driven to rotate by the driving motor 15. During the rotation, the screw 16 drives the suspended segmented air sampling mechanism to adjust the longitudinal height, thereby adjusting the distribution of the sampler 2.

[0030] Further improvement, such as Figure 2 As shown: the lifting adjustment frame includes a shell 18, a winding rod 19, a sling 20, a mounting seat 22 and a motor 23. The shell 18 is fixed to the bottom of the drone 1, and the winding rod 19 is rotatably arranged in the shell 18. The upper end of the sling 20 is wrapped around the winding rod 19 and the lower end is connected to the anti-airflow interference component. The mounting seat 22 is symmetrically installed on both sides of the winding rod 19. The motor 23 is installed on one group of the mounting seats 22 and the power output end is connected to the end of the winding rod 19. When it is necessary to adjust the height of the suspended segmented air sampling mechanism, in addition to controlling the flight altitude of the drone 1, the motor 23 can also be used to drive the winding rod 19 to rotate, so as to achieve the retraction and extension adjustment of the sling 20, and then adjust the height of the suspended segmented air sampling mechanism.

[0031] Further improvement, such as Figure 1 As shown: the extendable airflow shield 5 adopts an inflatable airbag, which has a cover-like structure and a concave structure in the middle. The surface of the inflatable airbag has a laminated structure. This design can reduce the airflow disturbance of the drone 1 in flight and improve the accuracy of air collection at each position.

[0032] Further improvement, such as Figure 1 As shown: several groups of samplers 2 are distributed in a stepped manner, and two adjacent groups of samplers 2 are connected by a sliding rod 14. This design can adjust the position of the collector 2 according to actual needs, which is convenient for collecting and processing air at different heights.

[0033] Further improvement, such as Figure 5 As shown: the magnetic shutter 10 includes a fixed ring 24, a movable ring 25, a blocking semicircle 26, an electromagnetic block 27 and a magnet 28. The fixed ring 24 is fixed between the pump body 9 and the air duct 11, and the movable ring 25 is rotatably arranged on the fixed ring 24. The blocking semicircle 26 is divided into two groups, and the two groups of blocking semicircles 26 are respectively fixed to the fixed ring 24 and the lower part of the inside of the movable ring 25. The electromagnet 28 is divided into two groups and symmetrically installed on the pump body 9. The magnet 28 is divided into two groups and symmetrically installed on the edge of the movable ring 25. Under normal conditions, the two groups of blocking semicircles 26 are in an overlapping state, and the collected air can enter the gas storage container 12. When the collection is completed, the electromagnetic block 27 pushes the magnet 28 to rotate in the energized state and cooperates with the weight of the magnet 28 on the other side to realize the rotation of the movable ring 25, so that the blocking semicircle 26 on the movable ring 25 closes the magnetic shutter 10, completing the collection and sealing of the air.

[0034] Further improvement, such as Figure 5 As shown: the upper magnetic pole of the electromagnetic block 27 is the same as the lower magnetic pole of the magnet 28 when the power is on. The electromagnetic block 27 pushes the magnet 28 to rotate when the power is on and cooperates with the weight of the magnet 28 on the other side to realize the rotation of the movable ring 25, so that the sealing semicircle 26 on the movable ring 25 closes the magnetically driven opener 10.

[0035] Further improvement, such as Figure 5 As shown: the weight of the two groups of magnets 28 is the same, and the electromagnetic block 27 and the magnet 28 are used in conjunction with each other.

[0036] Specifically, the air storage container 12 is spherical in structure and has a collection cavity 29 formed therein for storing the collected air.

[0037] When in use: When the drone 1 needs to be remotely controlled to the monitoring area, the air can be inflated by the air pump 4 and introduced into the extendable airflow shield 5. The extendable airflow shield 5 is extended and opened to block the disturbance of the drone 1 to the airflow below, thereby reducing the impact on the air. The screw 16 is driven to rotate by the driving motor 15. During the rotation, the screw 16 drives the suspended segmented air sampling mechanism to adjust the longitudinal height, thereby adjusting the distribution of the sampler 2. The winding rod 19 is driven to rotate by the motor 23 to achieve the retraction and extension adjustment of the suspension rope 20, thereby adjusting the height of the suspended segmented air sampling mechanism. When it is necessary to collect air, the air is extracted through the pump body 9, the air enters the air duct 7 through the air inlet hood 8 and enters the air storage container 12 along the air duct 11. Under normal conditions, the two sets of blocking semicircles 26 are in a superimposed state, and the collected air can enter the air storage container 12. When the collection is completed, the electromagnetic block 27 pushes the magnet 28 to rotate in the energized state and cooperates with the weight of the magnet 28 on the other side to realize the rotation of the movable ring 25, so that the blocking semicircle 26 on the movable ring 25 closes the magnetically driven opener 10, completing the collection and sealing of the air.
