Abstract
Description
Technical Field
[0001] This utility model relates to the field of drones, and in particular to a rapid loading and unloading drone for fire emergency. Background Technology
[0002] With the widespread application of drone technology in emergency rescue, its efficiency and flexibility in scenarios such as firefighting and material delivery have attracted much attention. Firefighters can use drones to carry rescue medicines and supplies, and use drones to deliver and replenish supplies, providing support for firefighting work. When it is necessary to frequently use drones to transport supplies, the loading and unloading speed of supplies on drones is particularly important. Existing drone mounting devices face problems such as complex structures and insufficient loading and unloading efficiency in complex environments. Mechanical clamps require manual assistance or precise alignment, which is time-consuming and cannot meet the time-sensitive needs of fire rescue. Therefore, there is an urgent need to develop a fire emergency rapid loading and unloading drone that can quickly unload, shorten emergency response time, and meet the needs of rapid material delivery in complex firefighting scenarios. Utility Model Content
[0003] To overcome the shortcomings of existing drone mounting devices, such as complex structures and insufficient loading and unloading efficiency in complex environments; and the fact that mechanical fasteners require manual assistance or precise alignment, which is time-consuming and cannot meet the time-sensitive needs of fire rescue, this utility model aims to provide a rapid loading and unloading drone for fire emergencies that can quickly unload, shorten emergency response time, and meet the needs of rapid material delivery in complex fire scenarios.
[0004] This utility model is achieved by the following specific technical means:
[0005] A fire emergency rapid loading and unloading drone includes a drone body and a loading and unloading device fixedly installed below the drone body.
[0006] The loading and unloading device includes a connecting frame fixedly connected to the lower end of the UAV body; a fixing plate is provided at the lower end of the connecting frame, and the fixing plate is fixedly connected to the connecting frame by bolts; at least two electromagnetic rods are also provided at the lower end of the fixing plate, and the electromagnetic rods are fixedly connected to the fixing plate by bolts; each electromagnetic rod includes an outer shell, and an iron core with a coil uniformly wound inside the outer shell is fixedly installed; a loading box is also provided below the fixing plate, with a cavity in the center of the loading box and an openable door on one side; a magnetic sleeve is provided on the loading box, corresponding to the electromagnetic rods, penetrating the upper and lower ends of the loading box and fixedly connected to the loading box; the magnetic sleeve on the loading box has a through hole in the center that fits into the surface of the outer shell of the electromagnetic rod.
[0007] Furthermore, the lower corner of the outer shell of the electromagnetic rod is provided with a rounded arc; this facilitates the quick insertion of the electromagnetic rod into the magnetic sleeve.
[0008] Furthermore, the upper corner of the magnetic sleeve is provided with an arc-shaped flared opening; this facilitates the quick insertion of the electromagnetic rod into the magnetic sleeve.
[0009] Furthermore, four electromagnetic rods are provided, equidistantly positioned at the four corners of the lower end of the fixed plate. Correspondingly, four magnetic sleeves are also provided on the loading box, which cooperate with the electromagnetic rods; this serves as a guide while improving the stability of the magnetic attraction.
[0010] Furthermore, the outer diameter of the outer shell of the electromagnetic rod is fitted with the through hole in the center of the magnetic sleeve to ensure smooth sliding between the outer shell and the magnetic sleeve and prevent jamming.
[0011] Furthermore, the magnetic sleeve is made of magnetic material.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention achieves rapid unloading, shortens emergency response time, and meets the needs of rapid material delivery in complex environments during firefighting scenarios. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: Example
[0021] A type of rapid loading and unloading drone for fire emergency response, such as Figure 1-5 As shown, it includes a drone body 1; and a loading and unloading device 2 fixedly installed below the drone body 1.
[0022] The loading and unloading device 2 includes a connecting frame 3 fixedly connected to the lower end of the UAV body 1; a fixing plate 4 is provided at the lower end of the connecting frame 3, and the fixing plate 4 is fixedly connected to the connecting frame 3 by bolts; at least two electromagnetic rods 5 are also provided at the lower end of the fixing plate 4, and the electromagnetic rods 5 are fixedly connected to the fixing plate 4 by bolts; the electromagnetic rod 5 includes an outer shell 51, and an iron core 52 with a coil evenly wound inside the outer shell 51 is fixedly provided; a loading box 6 is also provided below the fixing plate 4, the loading box 6 has a cavity in the center and an opening and closing door on one side; on the loading box 6, a magnetic sleeve 7 is provided through the upper and lower ends of the loading box 6 and fixedly connected to the loading box 6, relative to the electromagnetic rod 5; the magnetic sleeve 7 on the loading box 6 has a through hole in the center that fits into the surface of the outer shell 51 of the electromagnetic rod 5.
[0023] Working principle:
[0024] This utility model of drone, when used in fire emergency, works through the coordinated action of electromagnetic adsorption and mechanical guidance: the drone flies to the top of the loading box 6, then slowly descends, allowing the electromagnetic rods 5 to insert into the magnetic sleeves 7 on the loading box 6. The electromagnetic rods 5 are then energized, generating magnetic force to attract the magnetic sleeves 7. The rounded corners of the electromagnetic rods 5 and the arc-shaped flared opening at the top of the magnetic sleeves 7 form a dual guiding structure, ensuring that even with positional deviations, the four electromagnetic rods 5 can be quickly and accurately inserted into the through holes of the magnetic sleeves 7. The gap fit design ensures zero jamming during insertion, while the symmetrical layout at the four corners provides balanced force through multi-point magnetic attraction, improving the suspension stability of the loading box 6. Upon reaching the target position, the electromagnetic rods 5 are de-energized and demagnetized, instantly eliminating the attraction between the magnetic sleeves 7 and the electromagnetic rods 5. At this point, the loading box 6, under the influence of gravity, causes the magnetic sleeves 7 to separate and detach from the electromagnetic rods 5, achieving rapid unloading and significantly shortening the emergency response time.
[0025] The magnetic grabbing and instantaneous release are achieved through electromagnetic switching. Combined with the design of horn-shaped guide and four-corner distributed adsorption, it takes into account both precise positioning and anti-interference capabilities, and meets the needs of rapid material delivery in complex environments such as high altitudes and confined spaces in fire-fighting scenarios.
[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
[0027] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
