They are all common mobile module configurations, and the staff can equip them according to their needs. They are common knowledge of technicians in this field and will not be elaborated here.

[0040] In addition, if Figure 1 , Figure 6 and Figure 7As shown, the UAV platform 1 includes a tower body 11, which is divided into a plurality of docking layers 12 along its own height direction, and each docking layer 12 is connected and provided with a plurality of docking parts 13 along its own circumference direction, and each docking part 13 is used to receive the UAV, and a lifting and conveying room 14 for placing the UAV battery 7 and a lifting module (not shown in the figure) for driving the lifting and conveying room 14 to lift are slidably provided inside the tower body 11 along its own height direction, and a circulating power exchange mechanism 4 is arranged inside the lifting and conveying room 14. When the lifting and conveying room 14 is located at any docking layer 12, the lifting and conveying room 14 is connected to all the docking parts 13 of the corresponding docking layer 12, and the circulating distribution mechanism 3 is used to transport the batteries to be charged in the lifting and conveying room 14 to the idle charging cavity 5 and transport the fully charged batteries to the lifting and conveying room 14.

Several docking layers 12 and the docking parts 13 of each docking layer 12 form a multi-layer and multi-position docking system to provide docking stations for multiple UAVs, which can improve the distribution efficiency and the utilization rate of the vertical space, reduce the floor area, and the tower body 11 as a tower-type structure can provide outdoor wind protection for the UAV platform 1 as a whole, and enhance the stability and safety of the battery replacement operation of the UAV platform 1 under severe weather conditions.

[0041] Among them, the lifting module can use a take-up roller with a drive motor. By setting a rope on the top of the lifting and conveying room 14, the rope is wound on the take-up roller, and then the drive motor drives the take-up roller to rotate to control the winding or spreading of the rope, thereby realizing the control of the lifting and conveying room 14.

[0042] Furthermore, if Figure 1 As shown, multiple groups of circulating distribution mechanisms 3 and circulating power exchange mechanisms 4 are provided, and multiple boxes 2 are provided. The multiple groups of circulating distribution mechanisms 3 and multiple boxes 2 are radially distributed with the tower body 11 as the center. Through the radial distribution design with the tower body 11 as the center, it is convenient for each group of circulating distribution mechanisms 3 and circulating power exchange mechanisms 4 to handle the distribution and power exchange of multiple drone batteries 7 at the same time, which significantly improves the parallel processing capability of the system and improves the operation and maintenance efficiency of the drone battery automatic power exchange and charging system.

When the control system detects that the temperature in the charging cavity 5 is abnormally high or the smoke concentration exceeds the standard, the cooling fan 15 is started first to accelerate the air circulation in the charging cavity 5 to dissipate heat and cool down. If the temperature or smoke conditions continue to deteriorate and reach a preset threshold, the fire-fighting nozzles 10 will be automatically activated to spray gas fire extinguishing agents or water mist to extinguish the initial fire source, thereby effectively curbing the spread of fire and protecting the safety of the box 2 and the surrounding environment.

The fireproof frame 16 is arranged on the outside of the box body 2, and the fireproof roller shutter is arranged on the outside of the fireproof frame 16 and is used to close the fireproof frame 16. When the fireproof roller shutter closes the fireproof frame 16, the fireproof roller shutter and the fireproof frame 16 are arranged to form a closed space for closing the box body 2. When a fire occurs, the control system first controls the fireproof roller shutter to descend quickly and close the fireproof frame 16. At this time, the fireproof roller shutter and the fireproof frame 16 are jointly arranged to form a closed space to block the fire and smoke, thereby synergistically protecting the safety of the box body 2 and the surrounding environment and improving the safety of the equipment.

[0045] Furthermore, the automatic fire fighting system also includes a plurality of fire wall panels 17, and the box body 2 is divided into a plurality of charging chambers 5 by the plurality of fire wall panels 17. By setting the fire wall panels 17, the box body 2 can be divided into independent charging chambers 5. When a fire occurs, the fire inside the box body 2 can be prevented from spreading, so that the fire can be controlled in time, and the overall fire prevention capability and safety of the equipment can be further enhanced.

[0046] The implementation principle of an automatic battery replacement and charging system for unmanned aerial vehicles in an embodiment of the present application is as follows: when a unmanned aerial vehicle that needs battery replacement returns to the corresponding docking portion 13 of the unmanned aerial vehicle platform 1, under the action of the control system, the lifting and conveying room 14 moves to the corresponding docking layer 12, and the circulating battery replacement mechanism 4 inside the lifting and conveying room 14 takes out the battery to be charged of the unmanned aerial vehicle, and moves it to the bottom of the tower body 11 through the lifting and conveying room 14. At the same time, the circulating distribution mechanism 3 takes out the fully charged battery from the corresponding charging cavity 5 inside the box body 2, moves it to the bottom of the tower body 11 and docks it with the circulating battery replacement mechanism 4. After the battery replacement is completed in the lifting and conveying room 14, the lifting and conveying room 14 moves to the corresponding docking layer 12, and the circulating battery replacement mechanism 4 installs the fully charged battery to the unmanned aerial vehicle to complete the battery replacement work, and the circulating distribution mechanism 3 transfers the battery to be charged to the idle charging cavity 5 inside the box body 2, and completes the charging work through the replenishment module 6. The whole process does not require human intervention, forming a seamless and efficient unmanned aerial vehicle battery replacement and charging system.
