[0014] 2. The present invention is provided with a cover mechanism and a dust-proof mechanism. In the prior art, the battery replacement of the battery replacement station is exposed. In the present invention, the blower pumps clean air into the air duct, so that the air nozzle blows the clean air upward into the battery replacement chamber to prevent the external dusty air from entering the battery replacement chamber; the transmission device drives the two cover plates to slide towards each other or in the opposite direction to close or open the battery replacement chamber to prevent dust or foreign objects from entering the battery replacement chamber.

A moving block 33 is sleeved on the lead screw to drive the moving seat 34 to move back and forth; the moving seat 34 is arranged on the top side wall of the fixed seat 31 and is fixedly connected with the moving block 33. A conveyor belt device 35 is arranged in the notch on the top side wall of the moving seat 34 to convey several batteries forward. Several notches on the bottom side wall of the moving seat 34 are installation openings, and a fourth cylinder is fixed in each installation opening to drive the positioning frame 38 to move up and down; the front end of each limiting plate 36 is hinged with a push plate 37 through a hinge with a torsion spring to push the battery forward.

The two support plates 39 are respectively fixed on the left and right side walls of the front part of the fixed seat 31. A third cylinder 42 is fixed in the notch at the top of each support plate 39 for driving the charging plate 40 to move up and down.

The charging plate 40 is arranged directly above the support plate 39 and is fixedly connected to the top end of the telescopic rod of the third cylinder 42. The charging plate 40 is used to connect the power supply and the battery.

[0032] Two dust-proof nets 43 are fixed in the middle layer of the battery swapping chamber 44. The two dust-proof nets 43 are respectively arranged on the front and rear sides of the aircraft receiving mechanism. The dust-proof nets 43 prevent the dust on the wing from falling onto the replacement mechanism and the charging mechanism.

[0033] The structure of the control system 45 includes a control module, a system self-checking module, a dust detection module, a battery detection module, and a wireless communication module. The aircraft receiving mechanism, the replacement mechanism, the dust-proof mechanism, the cover mechanism, and the charging mechanism are all electrically connected to the control system and are controlled by the control module to operate. The system self-checking module detects whether the control system 45 has an error. The dust detection module is used to detect the dust in the battery swapping chamber 44. The battery detection module detects the quality of the battery. The wireless communication module wirelessly transmits data with the drone and the monitoring room.

[0034] The working principle of the present invention is as follows: Before use, a number of batteries are respectively placed on the conveyor belt device 35 between a number of pairs of limiting plates 36, and the first pair of limiting plates 36 at the front end is left empty without placing a battery. Under normal conditions, the moving seat 34 is at the front part of the fixed seat 31, and the third cylinder 42 drives the charging plate 20 to move downwards so that the charging terminal contacts the battery terminal for charging. The cover plate 12 is in the closed state under normal conditions.

[0035] When the drone needs to be charged, it sends a signal to the corresponding swapping station and hovers directly above the swapping station. The capping mechanism operates to open the cover plate 12: the first motor 16 drives the driving wheel to rotate, which then drives the belt 15 to rotate. The belt 15 drives the front cover plate 12 to slide through the connecting block 17, causing the front cover plate 12 and the rear cover plate 12 to slide in opposite directions to open the top port of the box body 10. At the same time, the dust-proof mechanism operates: the fan 20 draws the clean air in the air delivery pipe 21 into the air duct 18, causing the clean air to be sprayed upward from the air nozzle 19 into the power swapping chamber 44 to prevent the dusty air from outside from surging into the power swapping chamber 44. At the same time, the drone receiving mechanism operates: the second motor 24 drives the screw column 25 to rotate, causing the threaded sleeve to drive the moving plate 22 to slide upward to the top port of the box body 10. At the same time, the second cylinder 30 contracts, causing the support rod 29 to rotate upward, causing the drone receiving plate 26 to translate upward above the box body 10. Then the drone descends, and its two landing gears are respectively placed on the two drone receiving plates 26. After that, the second motor 24 and the second cylinder 30 drive in the reverse direction, causing the two drone receiving plates 26 to move towards each other and translate downward until the drone receiving plates 26 are placed on the fixed seats 31. The two drone receiving plates 26 push the landing gears to the middle in the left-right direction. At the same time, the first cylinder 28 drives the two clamping blocks to move towards each other to clamp the landing gears, positioning the landing gears in the middle in the front-back direction, so that when the drone falls into the power swapping chamber 44, the battery falls between the two vacant limiting plates 36.

[0036] Before the drone is positioned, the dust removal mechanism operates for a set time, causing the air nozzle to eject air onto the wings of the drone to blow off the dust on the wings. Then the capping mechanism and the dust removal mechanism are both closed at the same time. The cover plate 12 closes, and the air flow of the air nozzle 19 gradually decreases until the jetting stops when the cover plate 12 is completely closed.

[0037] Before the drone battery falls into the replacement mechanism, the third motor 32 drives the lead screw to rotate, causing the moving block 33 to drive the moving seat 34 to move backward, moving the limiting plate 36 at the vacant position to the falling position. When replacing the battery, the third motor 32 continues to drive the moving seat 34 to move backward. The pushing plate 37 pushes the battery on the drone backward and then detaches it from the drone, causing the fully charged battery in the second position to slide in and be installed on the drone.

[0038] After replacing the battery, the first cylinder 28 drives the clamping blocks 27 to move in the opposite direction to release the landing gears. The capping mechanism and the dust removal mechanism are both opened at the same time. As the jetting air flow increases, the dust-proof cover plate 12 gradually opens. After the cover plate 12 is completely opened, the drone starts and takes off with the assistance of the air flow from the nozzle 19. After the drone takes off, the capping mechanism and the dust removal mechanism are both closed again.

[0039] After the fully charged battery between a pair of limit plates 36 at the last position is replaced, the fourth cylinder drives the positioning frame 38 to move towards each other and then leaves the push plate 37. After the conveyor belt device 35 operates, several batteries are conveyed forward. The battery pusher enters behind the push plate 37 and moves to the next position, leaving the first position vacant. When the battery completely enters between a pair of limit plates 36 at the next position, the push plate 37 rotates inwards and resets under the action of the torsion spring. Then, the fourth cylinder drives the positioning frame 38 to move upwards and abut against the outside of the push plate 37. After cyclic transposition, the battery is moved under the charging plate 40 for charging.

[0040] After the cover plate is closed, the dust detection device is started. If the dust in the battery swapping station exceeds the standard, the duty personnel are notified through an alarm to manually clean the battery swapping station. During the charging process of the battery pack, the battery pack is detected. If the performance of the battery pack deteriorates or the charging interface is contaminated, resulting in a significant impact on the battery charging efficiency, charging speed, etc., the duty personnel are notified through an alarm to manually clean it. The battery swapping station has a system self-check function. Before the drone works, the battery swapping station should first complete the self-check. When it can work normally, it monitors the control room through communication, and then the drone takes off to work. If the self-check fails, the battery swapping station should be repaired first and then the drone can take off for inspection.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
