[0016] Beneficial effects: 1. A fast battery replacement and endurance device for a forestry UAV has a limited track embedded in the inner wall of the battery compartment. An electromagnet is installed inside the upper end of the limited track. When the UAV is flying, the electromagnet is energized to generate magnetic force. The electromagnet attracts the protruding circular magnetic material on the upper end of the moving rod to tightly fit the upper end of the moving rod to the upper end of the limited track. The lower end of the moving rod is connected to the limit plate in a rolling manner. When the upper end of the moving rod is fixed in the limited track, the movement of the limit plate is limited. Because electromagnetic sheets are designed on the opposite surfaces of the two limit plates, the two limit plates are merged when the UAV is in flight, the battery compartment is closed, and the electromagnetic sheet on the upper surface of the battery compartment is energized to generate magnetic force, and the battery is passed through the magnetic sheet on the upper surface. Fixed in the battery compartment; when the drone needs to change batteries, the multi-rotor drone lands vertically on the track of the battery exchange platform, and the support frame applies the overall gravity of the drone to the pressure sensor. The platform detects that the drone has landed, and the conveyor belt starts working. At the same time, after the drone stops, the propeller stops moving, the drone system is powered off, the electromagnetic sheet and the electromagnet are powered off at the same time, the magnetic force disappears, and the battery slides down under the action of gravity, and the moving rod moves to the lower end of the limit track, the magnetic force of the limit plate disappears, and it opens downward, and the battery falls onto the middle conveyor belt, completing the shedding. Compared with the existing drone battery exchange platform that often requires the use of robotic arms and other equipment, it greatly reduces the design cost and reduces the difficulty of maintenance.

[0017] 2. A fast battery replacement and endurance device for forestry UAV is designed with a conveyor belt. When the UAV lands vertically on the track, the pressure sensor transmits a signal to the conveyor belt, and the conveyor belt starts to move, and the battery on the conveyor belt is transported to the charging pile for charging. At the same time, the replacement battery in the middle of the charging pile moves to the position where the pressure sensor transmits a signal under the movement of the conveyor belt, that is, directly below the battery compartment of the UAV. When it reaches the designated position, the conveyor belt stops moving, and the conveying block with the replacement battery moves upward, and the replacement battery is placed upward into the battery compartment. After the UAV is powered on, the electromagnetic sheet and the electromagnet restore the magnetic force, adsorb and fix the battery, the pressure on the upper surface of the conveying block disappears, and it returns to its original position. At the same time, the electromagnet at the upper end of the limit track also causes the moving rod to return to the hollow part of the upper end under the action of the magnetic force, and the moving rod drives the limit plate to move, and the electromagnetic sheets on the outer surface of the limit plate attract each other, and the battery compartment is closed, completing the battery replacement.

[0028] See also Figure 1-6A forestry UAV fast battery replacement endurance device comprises a UAV part and a battery replacement platform part. The UAV part comprises a battery compartment 1, which is designed inside the UAV. A battery 2 is installed inside the battery compartment 1. A fixing plate 201 is designed on the upper surface of the battery 2. An electromagnetic sheet 4 is designed on the upper surface of the battery compartment 1. Two limit plates 7 are designed below the battery compartment 1. Electromagnetic sheets 4 are designed on the opposite surfaces of the two limit plates 7. Under the adsorption action of the electromagnetic sheets 4, the upper and lower surfaces of the limit plates 7 are both horizontal, forming a whole battery compartment 1 cover. The battery compartment 1 has two end surfaces embedded with limit rails 5, which are arc-shaped, hollowed out inside, and concentric with the limit rail 5. An electromagnet is installed inside the upper end of the limit rail 5, and a moving rod 6 is installed in the hollowed-out middle part of the limit rail 5. A sliding block 601 is designed on the upper end of the moving rod 6. The sliding block 601 is a circular protruding block connected to the limit rail 5. The diameter of the sliding block 601 is the same as the diameter of the hollowed-out part inside the limit rail 5. The moving rod 6 passes through the sliding block 6 01 moves by sliding inside the limiting track 5, the moving rod 6 has the freedom to move along the hollow part inside the limiting track 5, the lower end of the moving rod 6 is connected to the limiting plate 7, the moving rod 6 and the limiting plate 7 are rollingly connected, one side of the limiting plate 7 is connected to the bottom of the drone through a rotating shaft, the limiting plate 7 has the freedom to rotate and open along the rotating shaft, the fixed plate 201 and the sliding block 601 are both magnetic materials, the electromagnetic sheet 4 and the electromagnet are both connected to the drone signal, and the support frame 3 is installed on both sides of the lower surface of the drone. The support frame 3 is fixedly connected to the lower surface of the drone. When the drone has power, the electromagnetic sheet 4 and the electromagnet are energized, and when the drone has no power, the electromagnetic sheet 4 and the electromagnet are de-energized; the main body of the power exchange platform is a charging platform 11, and a circular track 12 is designed on the upper surface of the charging platform 11. A conveyor belt 10 composed of conveying blocks 101 is designed in the middle of the circular track 12. The conveyor belt 10 can move at a constant speed along the circular track 12 under circuit control. The vertical height of the conveyor belt 10 is higher than the surrounding track. The difference between the lowest point of the conveyor belt 10 and the circular track 12 is less than the length of the support frame 3. The various conveyor blocks 101 that constitute the conveyor belt 10 have freedom of movement in the vertical direction and can move up and down. A pressure sensor 8 is installed on the upper surface of the circular track 12. The output signal of the pressure sensor 8 is transmitted to the charging platform 11 and the conveyor belt 10. Charging piles 9 are installed on both sides of one side of the circular track 12. The charging method of the charging piles 9 is wireless charging. Replacement batteries are placed in the middle of the charging piles 9, and the replacement batteries are placed on the conveyor belt 10.

[0029] like Figure 2-3As shown, a fast battery replacement and endurance device for forestry UAV is designed. A limit track 5 is embedded in the inner wall of the battery compartment 1. An electromagnet is installed inside the upper end of the limit track 5. When the UAV is flying, the electromagnet is energized to generate magnetic force. The electromagnet attracts the protruding circular magnetic material on the upper end of the moving rod 6 to tightly fit the upper end of the moving rod 6 to the upper end of the limit track 5. The lower end of the moving rod 6 is rollingly connected to the limit plate 7. When the upper end of the moving rod 6 is fixed in the limit track 5, the movement of the limit plate 7 is limited. Because the opposite surfaces of the two limit plates 7 are designed with electromagnetic sheets 4, the two limit plates 7 are merged when the UAV is in flight state, the battery compartment 1 is closed, and the electromagnetic sheet 4 on the upper surface of the battery compartment 1 is energized to generate magnetic force, which passes the magnetic material on the upper surface to move the battery. The plate is fixed in the battery compartment 1; when the drone needs to change batteries, the multi-rotor drone lands vertically on the track of the battery exchange platform, and the support frame 3 applies the overall gravity of the drone to the pressure sensor 8. The platform detects that the drone has landed, and the conveyor belt 10 starts working. At the same time, after the drone stops, the propeller stops moving, the drone system is powered off, the electromagnetic plate 4 and the electromagnet are powered off at the same time, the magnetic force disappears, and the battery slides downward under the action of gravity, and the moving rod 6 moves toward the lower end of the limit track 5, the limit plate 7 loses its magnetic force and opens downward, and the battery falls onto the middle conveyor belt 10, completing the shedding. Compared with the existing drone battery exchange platform that often requires the use of mechanical arms and other equipment, the design cost is greatly reduced and the maintenance difficulty is reduced.

[0030] like Figure 4 As shown, a forestry UAV rapid battery replacement and endurance device is designed with a conveyor belt 10. When the UAV lands vertically on the track, the pressure sensor 8 transmits a signal to the conveyor belt 10, and the conveyor belt 10 starts to move, and the battery falling on the conveyor belt 10 is transported to the charging pile 9 for charging. At the same time, the replacement battery in the middle of the charging pile 9 moves to the position where the pressure sensor 8 transmits a signal under the movement of the conveyor belt 10, that is, directly below the battery compartment 1 of the UAV. When it reaches the specified position, the conveyor belt 10 stops moving, and the conveying block 101 with the replacement battery moves upward, and the replacement battery is placed upward into the battery compartment 1. After the UAV is powered on, the electromagnetic sheet 4 and the electromagnet restore the magnetic force to adsorb and fix the battery. The pressure on the upper surface of the conveying block 101 disappears and returns to its original position. At the same time, the electromagnet at the upper end of the limit track 5 also causes the moving rod 6 to return to the hollowed-out position at the upper end under the action of the magnetic force, and the moving rod 6 drives the limit plate 7 to move, and the electromagnetic sheet 4 on the outer surface of the limit plate 7 attracts each other, and the battery compartment 1 is closed, completing the battery replacement.

[0031] When in use, the drone first lands on the platform track according to the program. After the drone stops, the power is cut off, the electromagnet and the electromagnetic sheet 4 lose their magnetism, and the battery falls off from the battery compartment 1 to the conveyor belt 10 below. At the same time, the pressure sensor 8 on the upper surface of the circular track 12 detects that the drone has stopped, and the conveyor belt 10 starts to move. The conveyor belt 10 transports the battery to the charging pile 9 for charging. Under the action of the conveyor belt 10, the replacement battery in the charging pile 9 moves to the bottom of the drone battery compartment 1 according to the drone position signal sent by the pressure sensor 8 and then stops moving. After stopping, the conveying block 101 corresponding to the drone position moves upward to push the battery 2 into the battery compartment 1. After the battery 2 enters, the drone is powered on, the electromagnet and the electromagnetic sheet 4 restore their magnetism to fix the battery. At the same time, the electromagnet at the upper end of the limit track 5 generates magnetic force to suck the moving rod 6 back to the top of the limit track 5. The moving rod 6 drives the limit plate 7 to close. The electromagnetic sheets 4 on the opposite sides of the two limit plates 7 attract each other after touching, the battery compartment 1 is closed, and the drone completes the battery replacement.
