[0027] When the aircraft body 1 is in abnormal weather, the sensor 3 will detect the abnormal weather and start to issue signals and alarms, thereby driving the mounting plate 4 to descend in the mounting slot 21 of the mounting box 2, thereby driving the installed electronic device 41 to descend synchronously, and then through the setting of the first rotating shaft 22 and the second rotating shaft 23, the first cover plate 24 and the second cover plate 25 are driven to flip, and then the first cover plate 24 and the second cover plate 25 are abutted against the top of the mounting box 2, thereby closing the top of the mounting box 2, thereby forming a sealed space inside the mounting box 2, and then driving the secondary sealing mechanism 5 to work, thereby forming a re-sealing effect on the inside of the mounting box 2, and when the electronic device 41 works better, the secondary sealing mechanism 5 is first driven to open, and then the first cover plate 24 and the second cover plate 25 are driven to flip. 4 and the second cover plate 25 are rotated to abut against the aircraft body 1, and the first cover plate 24 and the second cover plate 25 are both provided with a magnetic attraction component 27, so that the first cover plate 24 and the second cover plate 25 have a fixed limit function when abutting against the aircraft body 1, and then the mounting plate 4 is driven to rise in the mounting groove 21, and then the electronic device 41 is moved out of the mounting box 2, so as to perform better work, and the secondary sealing mechanism 5 can form a re-sealing effect on the mounting box 2, so that the mounting box 2 has better sealing, so as to better protect the electronic device 41 on the mounting plate 4, and the first cover plate 24 and the second cover plate 25 are designed with an inclination when abutting against the aircraft body 1, so that the wind resistance of the aircraft body 1 can be reduced when it is flying horizontally, thereby reducing energy consumption.

When it is necessary to drive the electronic device 41 to move toward the top of the installation box 2, it is only necessary to drive the sealing plate 51 to move out of the limiting groove 52 of the installation box 2, so that the mechanism is simpler, thereby making it more stable during operation.

When the output end of the first rotating motor 531 rotates, the first bevel gear 532 is synchronously driven to rotate, and then the rotating screw rod 534 is synchronously driven to rotate through the setting of the second bevel gear 533, so that the connecting block 535 will move on the rotating screw rod 534, and then the sealing plate 51 can be synchronously driven to move in the limiting groove 52 of the mounting box 2, so that the sealing plate 51 can be directly driven to move by the operation of the first rotating motor 531, thereby reducing manual operation.
[0032] Reference Figure 3As shown, the installation box 2 is provided with a flipping and lifting mechanism 6, and the flipping and lifting mechanism 6 includes a connecting plate 63 and a rack 61; the connecting plate 63 has at least two, and the two connecting plates 63 are symmetrically arranged on the sealing plate 51, and the connecting plate 63 is slidingly connected to the installation box 2, and the installation box 2 is provided with a positioning groove 631 for the connecting plate 63 to move; the number of the racks 61 is the same as the number of the connecting plates 63 and is arranged on the connecting plates 63 in a one-to-one correspondence, and the first rotating shaft 22 and the second rotating shaft 23 are both provided with a toothed groove 62 that meshes with the rack 61.
[0033] When the first cover plate 24 and the second cover plate 25 are driven to flip over and abut against the mounting box 2, the first rotating shaft 22 and the second rotating shaft 23 will be driven to rotate in opposite directions respectively. When the first rotating shaft 22 and the second rotating shaft 23 rotate, the toothed groove 62 will synchronously drive the rack 61 to descend in the mounting box 2, and then the connecting plate 63 will directly drive the mounting plate 4 to descend in the mounting box 2. When the first cover plate 24 and the second cover plate 25 are flipped over and abut against the aircraft body 1, the rack 61 will synchronously rise in the mounting box 2, and then directly drive the mounting plate 4 to rise in the mounting box 2.
[0034] Reference Figure 4 and Figure 5 As shown, the aircraft body 1 is provided with a power assembly 64, and the power assembly 64 includes a second rotating motor 641, a limiting shaft 642, a third pulley 644 and a fourth pulley 646; the second rotating motor 641 is provided on the aircraft body 1, and the output end of the second rotating motor 641 is provided with a first pulley 6413 and a first gear 6412 respectively; the limiting shaft 642 is provided on a side of the aircraft body 1 close to the second rotating motor 641 through a fixing seat, and the limiting shaft 642 A second pulley 6422 and a second gear 6421 are respectively provided on it, and the second gear 6421 is meshingly connected with the first gear 6412; the third pulley 644 is provided on the extension end of the first rotating shaft 22, and the third pulley 644 is rotatably connected with the second pulley 6422 through the first belt 643; the fourth pulley 646 is provided on the extension end of the second rotating shaft 23, and the fourth pulley 646 is rotatably connected with the first pulley 6413 through the second belt 645.

When the output end of the second rotating motor 641 rotates counterclockwise, the first pulley 6413 and the first gear 6412 are synchronously driven to rotate counterclockwise. In this way, through the setting of the second belt 645, the fourth pulley 646 is synchronously driven to rotate counterclockwise, and then the second rotating shaft 23 is driven to rotate counterclockwise, so that the second cover plate 25 is rotated to abut against the installation box 2, and the When the first gear 6412 rotates counterclockwise, it will synchronously drive the second gear 6421 to rotate clockwise, so that through the setting of the limiting shaft 642, it will also synchronously drive the second pulley 6422 to rotate clockwise, and then through the setting of the first belt 643, it will synchronously drive the third pulley 644 to rotate clockwise, and then drive the first rotating shaft 22 to rotate clockwise, thereby driving the first cover plate 24 to rotate and abut against the installation box 2, and will synchronously drive the installation plate 4 to descend, which can further reduce manual operations.

[0037] The guide block 281 can only move in the guide groove 282 of the installation box 2, so as to guide and limit the installation plate 4 when it moves in the installation box 2, so that the installation plate 4 is more stable when moving.
[0038] Reference Figure 6 As shown, a guide wheel 2811 is also provided on the guide block 281 , and the guide wheel 2811 is rotatably connected to the installation box 2 .
[0039] By setting the guide wheel 2811, the friction between the guide block 281 and the installation box 2 can be reduced, so that the stability of the installation plate 4 can be further improved when the installation box 2 moves, and the power consumption can also be reduced.
[0040] Reference Figure 4 and Figure 5 As shown, sealing gaskets 26 are disposed on both the first cover plate 24 and the second cover plate 25 .
[0041] Because the first cover plate 24 and the second cover plate 25 are in hard contact with the installation box 2 , the sealing gasket 26 can provide a better sealing effect when the first cover plate 24 and the second cover plate 25 are in contact with the installation box 2 .
