The pipeline docking mechanism at the rear end is connected to the detection gas inlet of the air quality detector through the pipeline.

[0015] Preferably, a method for using an air pollution prevention and control detection device based on a complex network comprises the following steps: Step 1: Based on the influence of the atmospheric pollutant transmission network, namely the terrain factors, meteorological factors and pollutant factors, a complex network is constructed to identify the key nodes of the transmission path and arrange prevention and control detection boxes at key points in the region; Step 2: Start the prevention and control detection box. First, the hydraulic telescopic rod at the front end of the box controls the pipeline docking mechanism to extend, and the five docking joints on the pipeline docking mechanism are used to dock with the five solenoid valve interfaces at the front end of the sampling seat on the sampling drone. After completion, the terminal sends a signal to the solenoid valve interface and the vacuum pump, and starts the vacuum pump while opening the solenoid valve interface. The sampling chamber in the sampling seat is vacuumed under the action of vacuum pressure. After the vacuum pump pressure sensor component detects that the vacuum in the chamber is completed, it stops running and feeds back a signal to close the solenoid valve interface to keep the sampling chamber in a vacuum state; Step 3: The hydraulic telescopic rod is reset, and the guide rail is driven by the servo motor to run. The transmission effect of the forward and reverse screw rods is used to control the two box doors to move to both sides to unfold the prevention and control detection box. After completion, the hydraulic cylinder extends to control the lifting platform to move up, so that the sampling drone moves out of the prevention and control detection box. According to the sampling points in the area, a signal is sent to the sampling drone to make it fly along the predetermined track. Whenever a sampling point is reached, one of the solenoid valve interfaces on the sampling seat of the sampling drone is opened, so that the current ambient air flows into the sampling cavity corresponding to the solenoid valve interface, and so on. Since the sampling drone is equipped with five sampling cavities, one cruise can complete the sampling work of five monitoring points; Step 4: After the sampling drone completes sampling, it returns to the prevention and control detection box along the predetermined track. After being stably received by the lifting platform on the prevention and control detection box, the hydraulic cylinder resets and controls the drone to return to the prevention and control detection box. At the same time, the servo motor drives and controls the box door to close again; Step 5: After the sampling drone returns to the box, the hydraulic telescopic rod at the rear end of the box controls the pipeline docking mechanism to extend, and the five docking joints on the pipeline docking mechanism are used to dock with the five solenoid valve interfaces at the rear end of the sampling seat on the sampling drone. After completion, the terminal sends a signal to the solenoid valve interface and the air quality detector, and the solenoid valve interfaces are opened one by one to supply the sampled gas into the air quality detector in turn. The air quality detector monitors the samples in different sampling chambers in turn, and quickly completes the detection work of multiple monitoring points; Step 6: After the inspection is completed, in order to ensure that the sampling drone can quickly start the next inspection work, first drive the stepper motor to run, use the synchronous wheel and synchronous belt to control the C-type buckle to rotate one circle, drive the spring tongue lock handle to rotate, to unlock the connection between the lock tongue and the battery, then the first hydraulic push rod on the first pushing mechanism extends out, and pushes the battery in the battery holder along the pushing hole to the battery charging slot above the battery compartment until the battery docks with the interface in the battery charging slot, and is charged by the power module. Then the hydraulic cylinder controls the lifting platform to move down, so that the battery holder of the sampling drone is aligned with the battery charging slot below the battery compartment. After completion, the second hydraulic push rod on the second pushing mechanism is driven to push the internal battery into the battery holder along the pushing hole at the rear end of the battery charging slot. After completion, the hydraulic cylinder resets, drives the stepper motor in reverse, controls the C-type buckle to reverse one circle, re-locks the spring tongue lock, and tightens the battery to complete the battery replacement work.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a prevention and control detection box as the detection base station for each area. Because it is an integrated structure, it is convenient and quick to deploy. When working, a drone equipped with a sampling cavity is used as a sampling device. Before sampling, the sampling cavity is vacuumed by a vacuum device in the prevention and control detection box to avoid affecting the accuracy of subsequent sampling. During the sampling process, the sampling drone flies along a predetermined track under the action of the terminal signal. Whenever it reaches a sampling point, one of the solenoid valve interfaces on the sampling seat of the sampling drone is opened, so that the current ambient air can flow into the sampling cavity corresponding to the solenoid valve interface, and so on. Since the sampling drone is provided with five sampling cavities, the sampling work of five monitoring points can be completed in one cruise. After sampling, the drone returns to the prevention and control detection box, and can quickly complete the detection of multiple samples in cooperation with the air quality detector. It is convenient and quick, and solves the problem that traditional air monitoring sites require a lot of manpower and material resources to be deployed, and the detection efficiency is low. The sampling drone has a battery-changing structure. When one inspection is completed, in order to quickly start the next inspection, the stepper motor can be driven to run, and the synchronous wheel and synchronous belt are used to control the C-shaped buckle to rotate one circle, driving the spring tongue lock handle to rotate to unlock the connection between the lock tongue and the battery. Then the first hydraulic push rod on the first pushing mechanism extends out, and pushes the battery in the battery holder along the pushing hole to the battery charging slot above the battery compartment until the battery docks with the interface in the battery charging slot and is charged by the power module. Then the hydraulic cylinder controls the lifting platform to move downward to align the battery holder of the sampling drone with the battery charging slot below the battery compartment. After completion, the second hydraulic push rod on the second pushing mechanism is driven to push the internal battery into the battery holder along the pushing hole at the rear end of the battery charging slot. After completion, the hydraulic cylinder resets and drives the stepper motor in reverse to control the C-shaped buckle to reverse one circle, re-lock the spring tongue lock, and tighten the battery to complete the battery replacement work.

10. A method for using an air pollution prevention and control detection device based on a complex network, implemented based on the air pollution prevention and control detection device based on a complex network according to claim 9, characterized in that: The following steps are involved: Step 1: Based on the influence of the atmospheric pollutant transmission network, namely the terrain factors, meteorological factors and pollutant factors, a complex network is constructed to identify the key nodes of the transmission path and to arrange prevention and control detection boxes at key points in the region (1); Step 2: Start the prevention and control detection box (1). First, the hydraulic telescopic rod (144) at the front end of the box controls the pipeline docking mechanism (14) to extend, and the five docking joints (141) on the pipeline docking mechanism (14) are used to dock with the five solenoid valve interfaces (809) at the front end of the sampling seat (808) on the sampling drone (8). After completion, the terminal sends a signal to the solenoid valve interface (809) and the vacuum pump (15), opens the solenoid valve interface (809) and starts the vacuum pump (15) at the same time, and vacuumizes the sampling chamber in the sampling seat (808) under the action of vacuum pressure. After the pressure sensing component of the vacuum pump (15) detects that the vacuum in the chamber is completed, it stops running and feeds back a signal to close the solenoid valve interface (809), so that the sampling chamber remains in a vacuum state; Step 3: The hydraulic telescopic rod (144) is reset, and the guide rail (2) is driven by the servo motor (3) to run. The transmission action of the forward screw rod (6) and the reverse screw rod (7) is used to control the two box doors (4) to move to both sides, and the prevention and control detection box (1) is unfolded. After completion, the hydraulic cylinder (10) is extended to control the lifting platform (9) to move upward, so that the sampling drone (8) moves out of the prevention and control detection box (1). According to the sampling point in the area, a signal is sent to the sampling drone (8) to make it fly along a predetermined track. Whenever a sampling point is reached, one of the solenoid valve interfaces (809) on the sampling seat (808) of the sampling drone (8) is opened, so that the current ambient air flows into the sampling cavity corresponding to the solenoid valve interface (809), and so on. Since the sampling drone (8) is provided with five sampling cavities, one cruise can complete the sampling work of five monitoring points; Step 4: After the sampling drone (8) has completed sampling, it returns to the prevention and control detection box (1) along a predetermined track. After being stably received by the lifting receiving platform (9) on the prevention and control detection box (1), the hydraulic cylinder (10) is reset to control the drone to return to the prevention and control detection box (1). At the same time, the servo motor (3) is driven to control the box door (4) to close again. Step 5: After the sampling drone (8) returns to the box, the hydraulic telescopic rod (144) at the rear end of the box controls the pipeline docking mechanism (14) to extend, and the five docking joints (141) on the pipeline docking mechanism (14) are used to dock with the five solenoid valve interfaces (809) at the rear end of the sampling seat (808) on the sampling drone (8). After completion, the terminal sends a signal to the solenoid valve interface (809) and the air quality detector (16), and the solenoid valve interface (809) is opened one by one to supply the sampled gas into the air quality detector (16) in turn. The air quality detector (16) monitors the samples in different sampling chambers in turn, and quickly completes the detection work of multiple monitoring points; Step 6: After the test is completed, in order to ensure that the sampling drone (8) can quickly start the next test, the stepper motor (27) is first driven to operate, and the synchronous wheel and the synchronous belt are used to control the C-shaped buckle (29) to rotate one circle, driving the spring tongue lock (812) handle to rotate to unlock the connection between the lock tongue and the battery (811). Then, the first hydraulic push rod (22) on the first pushing mechanism (18) extends out and pushes the battery (811) in the battery holder (805) along the pushing hole (806) into the battery charging slot (24) above the battery compartment (19) until the battery (811) is docked with the interface in the battery charging slot (24), and the power module (13) connects it. After charging, the hydraulic cylinder (10) controls the lifting platform (9) to move downward, so that the battery seat (805) of the sampling drone (8) is aligned with the battery charging slot (24) below the battery compartment (19). After completion, the second hydraulic push rod (23) on the second pushing mechanism (20) is driven to push the internal battery (811) into the battery seat (805) along the rear end pushing hole (806) of the battery charging slot (24). After completion, the hydraulic cylinder (10) is reset, reversely drives the stepper motor (27) to run, controls the C-shaped buckle (29) to reverse one circle, re-locks the spring tongue lock (812), and tightens the battery (811) to complete the battery replacement work.
