[0029] Working principle: When in use, by placing the goods on the drawer 18, and then pushing the drawer 18 into the interior of the insulated cargo compartment 17, the goods can be placed in layers. At the same time, the keys on both sides of the drawer 18 slide in the card grooves on the inner side of the guide rail 19, so that the drawer 18 can be supported to move in a straight line. The setting of the insulated cargo compartment 17 can prevent the goods from being corrupted or melted during transportation. Then, when the goods are placed, the cabinet door on the insulated cargo compartment 17 can be closed to prevent the goods from falling during transportation. Then, the multi-rotor drone 3 can be turned on and fly to a specified height to transport the goods. During the transportation of the goods, the sensor in the insulated cargo compartment 17 is connected to the interior of the insulated cargo compartment 17. , so that the temperature and humidity sensor 10 can record and sense the temperature inside the insulated cargo compartment 17 in real time. At the same time, there is a wireless signal connection between the temperature and humidity sensor 10 and the external display terminal, so that the temperature and humidity sensor 10 can send a signal to the display terminal, which is convenient for the user to understand the temperature condition inside the insulated cargo compartment 17 in real time. When the supporting foot 2 needs to land, the multi-rotor drone 3 can contact the ground. Through the setting of the buffer spring 15, the vibration potential energy of the multi-rotor drone 3 can be absorbed to prevent the vibration potential energy from being transmitted to the temperature and humidity sensor 10. At the same time, through the setting of the plastic circular plate 12, the temperature and humidity sensor 10 can be prevented from colliding with the inner wall of the supporting cavity 16 when shaking, thereby avoiding damage to the temperature and humidity sensor 10 caused by vibration waves and completing the transportation of goods. When the temperature and humidity sensor 10 needs to be installed, the temperature and humidity sensor 10 can be placed inside the support frame 13 until the positioning rod 8 is inserted into the inside of the support base plate 14. At the same time, the pressing cross bar 9 can be rotated to be vertically aligned with the edge of the temperature and humidity sensor 10, and then the bolt 11 is screwed and rotated to drive the pressing cross bar 9 to move downward, so that the temperature and humidity sensor 10 can be squeezed and restricted on the support base plate 14. When the device is in use, the combination of the buffer spring 15 and the plastic circular plate 12 can prevent the vibration fluctuations generated by the multi-rotor drone 3 during landing from affecting the temperature and humidity sensor 10, thereby improving the service life of the temperature and humidity sensor 10. At the same time, the sensing head in the temperature and humidity sensor 10 and the The insulated cargo compartment 17 is internally connected, so that the temperature inside the insulated cargo compartment 17 can be transmitted in real time to the temperature and humidity sensor 10 for display. When the device is in use, when the multi-rotor drone 3 is in flight mode, the electric push rod 22 can be started to drive the U-shaped positioning frame 21 to move toward the inner center of the support cavity 16 until the U-shaped positioning frame 21 contacts the outer surface of the support frame 13, so that the support frame 13 can be restricted and fixed to prevent the temperature and humidity sensor 10 from shaking when the multi-rotor drone 3 is flying. At the same time, through the provision of the plastic strip 20, the U-shaped positioning frame 21 can be prevented from causing damage to the surface of the support frame 13, and the positioning work of the support frame 13 is completed. When the multi-rotor drone 3 needs to land, the electric push rod 22 can be started again.The U-shaped positioning frame 21 is driven to move toward one end away from the support frame 13, so that the U-shaped positioning frame 21 can be out of contact with the support frame 13. At this time, there is a gap between the support frame 13 and the support cavity 16, and the buffer spring 15 is connected to the outer surface of the support frame 13, so that when the multi-rotor drone 3 lands, the support frame 13 can shake up and down inside the support cavity 16 to avoid the temperature and humidity sensor 10 from colliding with the support cavity 16. When the device is in use, a wireless communication module is installed inside the multi-rotor drone 3, and the wireless communication module has a wireless signal connection with the temperature and humidity sensor 10 and the temperature and humidity alarm module 24, so that the wireless communication module can transmit the working information of the temperature and humidity sensor 10 to the outside world.
