[0028] like Figure 1-12 As shown, as a preferred embodiment of the utility model, the surface of the UAV platform 6 is provided with an electric linear guide clamp 12, and the surface of the UAV platform 6 is provided with an electric linear guide wide clamp 13, and the electric linear guide clamp 12 and the electric linear guide wide clamp 13 are respectively connected to the laser position sensor 15.

[0029] like Figure 1-12 As shown, as a preferred embodiment of the present utility model, the Y-axis pulley 22 is composed of a pulley 221 and a turbine motor 222 , and the output shaft of the turbine motor 222 is connected to the pulley 221 .

[0030] like Figure 1-12 As shown, as a preferred embodiment of the utility model, the vertical transport platform 5 includes a vertical transport ladder rack 51, a vertical transport ladder gear set 52 is arranged on the surface of the vertical transport ladder rack 51, a vertical transport ladder gear motor 53 is arranged on the surface of the vertical transport ladder gear set 52, the vertical transport ladder gear motor 53 is connected to a vertical transport ladder loading platform 54, and a laser ranging radar 55 is arranged on the surface of the vertical transport ladder loading platform 54.

[0031] like Figure 1-12As shown, as a preferred embodiment of the utility model, the Z-axis lifting gear motor group 23 includes a Z-axis gear 231 , the Z-axis gear 231 is connected to a gear group motor 232 , and the output shaft of the gear group motor 232 is connected to the Z-axis gear 231 .

[0032] The working principle of the utility model is: when the battery of the drone 11 is almost exhausted and needs to be replaced, the drone 11 lands on the square drone platform 6, and the laser position sensor 15 works at this time. The laser position sensor 15 is an existing positioning instrument on the market that emits a laser beam and reflects it through an object to locate. When the drone 11 lands, the laser of the laser position sensor 15 irradiates the drone 11 to detect the real-time height of the drone 11. When it is detected that the drone 11 has completely landed, a signal is sent to the electric linear guide fixture 12 and the electric linear guide wide fixture 13, which slide synchronously toward the drone 11 through the slide rail, and fix the landing gear of the drone 11 through the fixture on the electric linear guide until the drone battery compartment is parallel to the battery loading port. The electric linear guide fixture 12 and the electric linear guide wide fixture 13 are fixed under the landing gear by screws and nuts, and are connected to the energy storage lithium battery 4 through wires.

[0033] After that, the vertical transport platform 5 starts working, and the vertical transport ladder gear motor 53 and the vertical transport ladder gear set 52 are connected through the bayonet to transmit power to the vertical transport ladder gear set 52, so that it can rise through the meshing connection of the vertical transport ladder rack 51 and the vertical transport ladder gear set 52 to drive the vertical transport ladder loading platform 54 to rise, until the laser ranging radar 55 detects that the distance between the vertical transport ladder loading platform 54 and the battery compartment of the drone 11 is zero, and is connected to the vertical transport ladder gear motor 53 through wires, and the vertical transport ladder gear motor 53 is connected to the energy storage lithium battery 4 through wires to provide it with power.

[0034] After that, the drone 11 rotates the two battery locking mechanisms 14 through internal system instructions. The battery locking mechanism 14 is composed of a motor and a locking slider. When the motor rotates, it drives the locking slider to rotate and rotate out or into the drone 11. The battery locking grooves 321 on both sides of the drone battery 32 achieve the effect of locking and unlocking the drone battery. After the battery locking mechanism 14 is unlocked, the battery can fall steadily on the vertical transport ladder loading platform 54 with gravity, and then the vertical transport ladder loading platform 54 carrying the battery descends to a fixed height.

[0035] When the vertical conveyor platform 54 carrying the battery descends to a fixed height, the three-axis forklift arm works. The three laser millimeter wave radars 241 on the forklift arm assembly 24 locate the precise position of the battery through millimeter waves. After the laser millimeter wave radar 241 determines the three-dimensional coordinates of the drone battery 32, the pulley motor 222 and the pulley 221 are connected by a bayonet connection to transmit power to the pulley 221, so that it can move forward and backward on the Y-axis pulley guide rail 21, thereby driving the overall movement. The pulley motor 222 is connected to the energy storage lithium battery 4 through wires to supply energy for it. The Z-axis lifting rack set 26 is fixed to the pulley 221 by bolts, and then the gear set motor 232 and the Z-axis gear 231 are connected by a bayonet connection with the Z-axis gear 231 and the Z-axis lifting rack set 26, and then the energy storage lithium battery 4 is connected to the gear set motor 232 by wires to supply energy for it, so that it can move up and down the Z-axis lifting rack set 26. Then, through the movement of the slider on the X-axis electric linear guide 25, the X-axis electric linear guide 25 is fixed to one side of the two gear group motors 232 by screws and nuts, and the X-axis electric linear guide 25 is connected to the energy storage lithium battery 4 through wires for power supply. Through the Y-axis movement of the Y-axis pulley guide 21 and the Y-axis pulley 22, the Z-axis movement of the Z-axis lifting gear motor group 23 and the Z-axis lifting rack group 26, and the X-axis movement of the X-axis electric linear guide 25, the forklift arm assembly 24 can achieve three-axis movement.

[0036] Then, the forklift arm assembly 24 moves through three axes, and through the precise three-dimensional spatial coordinates of the drone battery, the forklift arm assembly 24 can move accurately to the front of the drone battery and pick up the drone battery with the forklift arm through three-axis movement. After the laser millimeter wave radar 241 locates the empty battery charging compartment 31, it transports the drone battery to the empty battery charging compartment 31 through three-axis movement for energy replenishment and charging.

[0037] After the exhausted drone battery 32 is returned to the battery charging compartment 31 for charging, the laser millimeter wave radar 241 on the forklift arm assembly 24 begins to reposition to a three-dimensional coordinate system of a fully charged drone battery. Then, through the overall three-axis movement, the forklift arm assembly 24 forks the fully charged drone battery onto the vertical conveyor ladder loading platform 54, and ensures that the groove at the bottom of the drone battery corresponds to the groove on the vertical conveyor ladder loading platform 54 and moves it out to a position that does not affect the operation of the lifting platform. The groove at the bottom of the drone battery 32 corresponds to the groove on the vertical conveyor ladder loading platform 54, which ensures that the drone battery can be smoothly returned to the battery compartment of the drone. Through the meshing of the vertical conveyor ladder gear set 52 and the vertical conveyor ladder rack 51, the power provided by the vertical conveyor ladder gear motor 53 drives the vertical conveyor ladder loading platform 54 to rise, thereby driving the fully charged drone battery to move upward. When the laser ranging radar 55 measures that the distance to the bottom of the drone is 0, the vertical conveyor ladder loading platform 54 stops, which means that the fully charged drone battery has been loaded into the battery compartment of the drone. The drone electrode sheet 111 has a metal spring, so the drone electrode sheet 111 and the drone battery positive and negative plates 322 can ensure a good connection to power on the drone. The drone is back online and detects that the battery replacement is complete, and fixes the drone battery 32 through the battery locking mechanism 14. Then the electric linear guide fixture 12 and the electric linear guide wide fixture 13 move in the opposite direction, releasing the fixed drone 11, and the drone 11 takes off again. At this point, the drone 11 is fully powered.

[0038] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
