[0050] Working principle: when in use, start the lifting motor 103, the lifting motor 103 drives the lifting threaded column 105 to rotate, the lifting threaded column 105 pushes the lifting threaded block 106 to make the car 109 drop to the bottom, the AGV automatic guided vehicle enters the upper machine frame 201 along the surface of the anti-slip pad 202, and then enters the car 109, and then starts the lifting motor 103 again to drive the car 109 to rise to one side of the empty charging mechanism, and then the AGV automatic guided vehicle enters the corresponding charging mechanism, and then starts the door motor 404, the door motor 404 drives the door threaded rod 405 to rotate, and when the door threaded rod 405 rotates, it pushes the door threaded block 406 to drop, so that the isolation door 403 is closed, and then the electromagnet 520 above the corresponding charging mechanism is energized, and the electromagnetic The iron 520 is energized to attract the nickel block 518, and the locking block 516 is attracted and slides, so that the locking tooth groove 517 is separated from the locking gear 514, and then the clamping motor 510 is started. The clamping motor 510 drives the winding wheel 512 to rotate through the transmission shaft 511. When the winding wheel 512 rotates, the pressing belt 513 is rolled up, and the rolled up pressing belt 513 presses down the lifting frame 501. The lifting frame 501 squeezes the rubber spring sheet 307 through the sliding plate 502 to descend and deform, so that the rubber buffer pad 308 presses and fixes the AGV automatic guided vehicle below, and then the electromagnet 520 is powered off, and the locking spring 521 is reset to push the locking block 516 to engage and lock the locking gear 514, and then the wireless charging module 304 is started to wirelessly charge the AGV automatic guided vehicle;

[0051] After charging is completed, the electromagnet 520 above the corresponding charging mechanism is energized, and the electromagnet 520 is energized to attract the nickel block 518, and the locking block 516 is attracted and slides, so that the locking tooth groove 517 is separated from the locking gear 514, and then the clamping motor 510 is started, and the clamping motor 510 drives the winding wheel 512 to rotate in the opposite direction through the transmission shaft 511. When the winding wheel 512 rotates, the winding of the pressing belt 513 is released. After the pressing belt 513 is released, the lifting frame 501 is pushed up by the reset spring 505, the rubber spring sheet 307 is reset, and the rubber buffer pad 308 releases the clamping and fixing of the AGV automatic guided vehicle below, and then the electromagnet 520 is de-energized, and the locking spring 521 is reset to push the locking block 516 to lock the locking gear 514. Engage the lock position, and at the same time close the wireless charging module 304 to wirelessly charge the AGV automatic guided vehicle, then start the door motor 404, the door motor 404 drives the door thread rod 405 to reverse, thereby pushing the door thread block 406 and the isolation door 403 to rise, and at the same time start the lifting motor 103, the lifting motor 103 drives the lifting thread column 105 to rotate, the lifting thread column 105 pushes the lifting thread block 106 to make the car 109 reach the charging mechanism side of the corresponding position, the fully charged AGV automatic guided vehicle enters the car 109, and then start the lifting motor 103 again to transport the car 109 to the bottom, and then the AGV automatic guided vehicle enters the upper machine frame 201 from the inside of the car 109 and finally returns to the ground;

[0052] After the fire extinguisher 619 is installed, it is necessary to open the safety valve 620 to put the fire extinguisher 619 in a state ready to spray. When a fire occurs, the inside of the charging mechanism will heat up, and the heat will burn the heat conducting plate 604 to increase its temperature. The heat conducting plate 604 heats the wax block 617 through the heat conducting sheet 610. The wax block 617 expands due to the heat and pushes the isolation piston 614 to rise. When the isolation piston 614 rises, it drives the crushing cone 615 to rise. When the crushing cone 615 rises to a certain extent, it will squeeze and pierce the hollow glass column 613. After the hollow glass column 613 is pierced, the guide channel 611 is connected, and the high pressure inside the fire extinguisher 619 will squeeze the dry powder into the feed pipe 607, and then enter the guide channel 611 and the discharge pipe 606, and finally spray into the charging mechanism from the nozzle 608 to extinguish the fire.
