[0026] Furthermore, the container building 1 is equipped with a food collection structure 4 located below the food drop-off port 303. The food collection structure 4 is used to collect the food boxes delivered by the drone through the food drop-off port 303. Since the drone delivers food from the top of the roof 101, which is at a high height, it is not convenient for people to pick it up directly. However, the food collection structure 4 can collect the food boxes, thereby lowering the height of the food boxes so that they can be picked up by people.

[0027] Furthermore, the food collection structure 4 includes a base plate 401 installed inside the box-type building 1. Several columns 402 are installed on the top of the base plate 401. A first support plate 403 and a second support plate 404 located below the first support plate 403 are installed between the front sides of the columns 402.

Several support frames 408 are installed on the front side of the connecting plate 407, and a platform 409 is connected between the tops of the multiple support frames 408. Several limiting plates 410 are installed on the top of the platform 409. The top of the platform 409 is used to receive the food box, and the limiting plates 410 are used to limit the food box on the top of the platform 409 to reduce the possibility of the food box falling.

[0028] Furthermore, a plurality of slide rails 405 are connected between the first support plate 403 and the second support plate 404, and slide blocks 406 are slidably connected on the slide rails 405, with the slide blocks 406 connected to the back of the connecting plate 407.

[0029] Furthermore, the driving component includes a mounting bracket 411 mounted on the top of the base plate 401 and a third mounting seat 412 mounted on the first support plate 403. A third lead screw 413 is rotatably connected between the third mounting seat 412 and the mounting bracket 411 via a bearing. A third motor 414 is mounted on the top of the base plate 401, and the output shaft of the third motor 414 is connected to the third lead screw 413 via a coupling. The third motor 414 can drive the third lead screw 413 to rotate.

[0030] Furthermore, the outer surface of the third lead screw 413 is threaded with a lead screw nut, and the lead screw nut is bolted to a connecting block. The connecting block is connected to the connecting plate 407. During the rotation of the third lead screw 413, the connecting plate 407 can be driven to rise and fall through the lead screw nut and the connecting block, thereby driving the support frame 408 and the platform 409 to rise and fall.

[0031] Furthermore, the side of the container building 1 is provided with multiple windows, and a cover 102 located at the window is rotatably connected to the container building 1. The window setting facilitates communication between the orderer and the staff and the picking up of the food.

[0032] Furthermore, several hydraulic struts 103 are hinged between the cover 102 and the box-type building 1, and the hydraulic struts 103 are used for support after the cover 102 is opened.

[0033] Furthermore, a warming cabinet 106 is installed inside the container building 1, and a shelf 107 is installed on the top of the warming cabinet 106. The warming cabinet 106 is used to keep the food warm before the orderer arrives.

[0034] Furthermore, an operating table 105 is connected between the container building 1 and the insulated cabinet 106, and the position of the operating table 105 corresponds to the position of the window; a protective door 104 for staff to enter and exit is also provided on the container building 1.

[0035] Furthermore, a camera 5, a rain sensor 501, a wind speed sensor 502, and an alarm 503 are connected to the top of the roof 101. A controller is connected between the camera 5, the rain sensor 501, the wind speed sensor 502, and the alarm 503. The third motor 414, the first dual-axis motor 304, and the second dual-axis motor 308 are all connected to the controller. The controller can be a PLC controller. The structures of the camera 5, the rain sensor 501, the wind speed sensor 502, the alarm 503, the third motor 414, the first dual-axis motor 304, and the second dual-axis motor 308 are all existing components. Their specific structures, control principles, and circuit connections are all existing technologies, and will not be described in detail in this application.

[0036] The low-altitude canteen provided by this utility model is used as follows: The linear module drives the protective cover 2 to move, exposing the centering structure 3. The delivery drone then lands on the top of the top plate 301 in the area corresponding to the food drop opening 303. The second dual-axis motor 308 drives the second mounting base 310 to move via the second lead screw 309. The second mounting base 310 drives the second centering plate 312 and the first centering plate 311 to move, pushing the drone above the food drop opening 303. The first dual-axis motor 304 drives the two first lead screws 305 to rotate. During the rotation of the first lead screw 305, the two third centering plates 313 are driven to move closer to each other through the first mounting base 306 to further adjust the position of the drone, so that the drone's meal box can be aligned with the food drop sill 303. The platform 409 rises, and the meal box falls from the food drop sill 303 onto the platform 409. Then the platform 409 drives the meal box to descend, and the staff takes out the meal from the meal box. The taken-out meal can be temporarily stored in the warming cabinet 106 to keep it warm or directly given to the person who ordered the meal. The person who ordered the meal can take the meal away or eat directly at the seat.
