[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1. In this invention, the electromagnetic plate uses its own magnetic field to push the magnetic plate at its top, simultaneously pulling several connecting ropes on its outer wall. These ropes then pull the bottom of the elastic rubber cover towards the outer wall of the top cover, making the elastic rubber cover more stable and preventing it from falling off. Once the aircraft rises to a designated position in the air, several jet nozzles stop spraying air, and the magnetic plate and electromagnetic plate attract each other. As the magnetic plate moves downwards, the pull on the connecting ropes loosens, and the jet valve delivers air from inside the storage tank to the exhaust pipe, which then blows the air onto the elastic rubber cover. The internal space of the elastic rubber cover expands, and during use, the operator can adjust the jet intensity of the exhaust pipe through the jet valve. The air blown by the jet valve blows through the elastic rubber cover, causing the elastic rubber cover to lift the aircraft slightly. During use, the height of the aircraft can be adjusted by the jet intensity of the jet valve and the exhaust pipe, allowing the aircraft to briefly hover or slowly descend at a designated position in the air. The jet head lifts the aircraft to a designated position in the air, and the exhaust pipe and elastic rubber cover allow the aircraft to move slowly at the designated position in the air, facilitating accurate pollution detection of the air at the designated position in the air.

[0018] 2. The flow monitor inside the fixed sleeve in this invention can detect the amount of air entering the fixed sleeve. When in use, it can cooperate with the laser dust sensor and gas sensor to detect the air. At the same time, it can detect the amount and composition of particles in a certain amount of air, making the air pollution detection results more accurate. The air after pollution detection can be stored in the storage tank for use by the air outlet pipe and jet head. It can also be used to move the air body in the air and slow down the downward speed, making it easier for the air body to move to the designated position for accurate air pollution detection.

[0019] 3. In this invention, several jet heads simultaneously spray air downwards onto the base plate, and the reverse thrust of the jet heads propels the aircraft upwards and into the air. The leveling device located at the bottom of the aircraft body can detect the horizontal position of the bottom of the aircraft body in real time during use. The leveling device is electrically connected to the several jet heads, and the spray intensity of the several jet heads can be adjusted according to the detection result of the horizontal position at the bottom of the aircraft body during use. The tilt position of the aircraft body during takeoff can be adjusted in real time, so that the aircraft body can rise to a designated position in the air through the jet heads.

[0020] 4、The staff in the application through the body to the air designated position of air pollution detection is completed, the staff can be through the electromagnetic plate of magnetic field repulsion force again push magnet plate sliding, and pull the elastic rubber cover cover on the outer wall of the machine top cover, at the same time, the air pipe stops blowing to the inside of the elastic rubber cover, while the several jet head located at the bottom of the machine body can again push the machine body to the air designated position, and through the jet intensity adjustment of several jet head, can move to a certain degree of steering when the machine body, until the machine body moves to the air designated position, and again to the air pollution detection, in use, can be in turn to the air different position for air pollution detection, without the machine for many times of ascension, use more convenient.

[0042] In use, the worker inserts the storage tank 7 to be used into the inside of the body 1 from the top end of the body 1, and the top block 15 and the bottom block 16 on the outer wall of the storage tank 7 slide between the two adjacent fixed sleeves 14 on the inner wall of the body 1 until the bottom end of the bottom block 16 abuts against the top of the supporting ring 17, and then the worker can rotate the storage tank 7 so that the top block 15 and the bottom block 16 are located at the two ends of the fixed sleeve 14 respectively, and the limiting hole 19 on the top block 15 communicates with the limiting hole 19 on the fixed sleeve 14.

When installing the machine top cover 2, the top end of the air outlet pipe 11 is inserted into the supporting hole 31 at the top end of the machine top cover 2, which can improve the stability of the top end of the machine top cover 2 in use.

[0043] The worker places the body 1 on the ground at a designated position, and a certain amount of compressed air is stored in the storage tank 7, and at the same time, the elastic rubber cover 3 is sleeved on the outer wall at the top end of the machine top cover 2, and the electromagnetic plate 26 at the top end of the storage tank 7 generates a magnetic field, and the repulsive force of the magnetic field pushes the magnet plate 30 at the top end to slide on the outer wall of the air outlet pipe 11 away from the body 1 until the magnet plate 30 moves to the inner top of the machine top cover 2. When the magnet plate 30 moves, the plurality of connecting ropes 28 on the outer wall can be pulled, and the connecting ropes 28 can pull the elastic rubber cover 3 on the outer wall of the machine top cover 2, so that the elastic rubber cover 3 close to the edge is tightly attached to the outer wall of the machine top cover 2 through the pulling of the connecting ropes 28, and at the same time, the flowing air generated when the body 1 rises through the air jet head 13 can make the middle position of the elastic rubber cover 3 tightly attached to the outer wall at the top end of the machine top cover 2. The elastic rubber cover 3 has strong self-stretching property, and the U-shaped elastic rubber cover 3 can cover the outer wall of the machine top cover 2, which will not affect the rising of the body 1 in use.

[0044] In use, the air in the storage tank 7 is delivered to the inside of the plurality of air jet heads 13 through the connecting block 8, and the plurality of air jet heads 13 can simultaneously jet air downward of the bottom plate 4, and the air jet head 13 pushes the body 1 to move upward of the ground through the counter thrust of the air jet, and the leveler 9 at the bottom of the body 1 can detect the horizontal position of the bottom end of the body 1 in real time in use, and the leveler 9 and the plurality of air jet heads 13 are electrically connected with each other, so that the jet intensity of the plurality of air jet heads 13 can be adjusted according to the detection result of the horizontal position of the bottom of the body 1 in use, and the inclination position of the body 1 rising in the air can be adjusted in real time, so that the body 1 can rise to a designated position in the air through the plurality of air jet heads 13.

[0045] When the machine body 1 rises above the specified position in the air, the several jet heads 13 stop jetting, and the magnetic field of the electromagnetic plate 26 is adjusted to attract the magnetic plate 30, causing the magnetic plate 30 to move on the outer wall of the air outlet pipe 11 towards the electromagnetic plate 26, and the magnetic plate 30 and the electromagnetic plate 26 are attracted to each other. When the magnetic plate 30 moves down, the magnetic plate 30 loosens the pulling of the connecting rope 28, and after the machine body 1 rises to the specified position and the jet heads 13 stop jetting, the machine body 1 will descend, and the flowing gas generated during the descent will enter the interior of the elastic rubber cover 3 from the position between the edge of the elastic rubber cover 3 and the outer wall of the machine top cover 2, causing the elastic rubber cover 3 to collide, similar to landing, slowing down the descent of the machine body 1.

[0046] When the elastic rubber cover 3 expands, the air inside the storage tank 7 is transported to the interior of the air outlet pipe 11 by the air jet valve 20, and the air is blown into the interior of the elastic rubber cover 3 through the air outlet pipe 11, causing the interior space of the elastic rubber cover 3 to expand. During use, the staff can adjust the jetting intensity of the air outlet pipe 11 by the air jet valve 20, causing the air blown by the air jet valve 20 to blow the elastic rubber cover 3, causing the elastic rubber cover 3 to slightly lift the machine body 1. During use, the height of the machine body 1 can be adjusted by the jetting intensity of the air jet valve 20 and the air outlet pipe 11, causing the machine body 1 to be temporarily suspended or slowly descend at a specified position in the air.

[0047] During use, the staff can install an air pump inside the storage tank 7, and the air pump is connected to the several gas sensors 21, causing the air pump to draw air into the several fixed sleeves 14 through the several gas sensors 21, and the air outside can enter the interior of the fixed sleeve 14 through the air inlet hole 6 and the through hole 18, and is transported into the interior of the bottom block 16. The flow monitor 32 inside the fixed sleeve 14 can detect the amount of air entering the interior of the fixed sleeve 14, and during use, it can cooperate with the laser dust sensor 25 and the gas sensor 21 to detect the air, and detect the amount and composition of a certain amount of air, making the results of air pollution detection more accurate. After being detected by the flow monitor 32, the air enters the interior of the connecting hole 22 of the bottom block 16, and the laser dust sensor 25 inside the connecting hole 22 can detect the dust particle content in the air entering the interior of the connecting hole 22. After being detected by the laser dust sensor 25, the air enters the interior of the storage tank 7 through the gas sensor 21, and the gas sensor 21 can detect the concentration of carbon dioxide, carbon monoxide, nitrogen oxides and other gas pollutants in the air.

[0048] When the staff finishes detecting the air pollution of the specified position in the air through the body 1, the staff can push the magnet plate 30 to slide again through the magnetic field repulsion force of the electromagnetic plate 26, and pull the elastic rubber cover 3 to cover the outer wall of the machine top cover 2, at the same time, the air outlet pipe 11 stops blowing air to the inside of the elastic rubber cover 3, and the several air jet heads 13 at the bottom end of the body 1 can push the body 1 to move to the specified position in the air again, and through the adjustment of the air jet intensity of the several air jet heads 13, the body 1 can be turned to a certain extent when moving, until the body 1 moves to the specified position in the air, and detects the air pollution again.
