[0015] S1. When the top cloth needs to be retracted into the storage box, the drive mechanism is opened through the control panel. The drive mechanism drives the installation shaft to rotate when it works. The rotation of the installation shaft drives the guide mechanism through the linkage mechanism, and the guide mechanism drives the top cloth to slide along the support frame towards the storage box.

[0047] The present invention also discloses a usage method of the ceiling system based on a large-span outdoor basketball court, which specifically includes the following steps:

[0048] S1. When it is necessary to retract the top cloth 9 into the storage box 2, the driving mechanism 4 is turned on through the control panel. The driving mechanism 4 works to drive the mounting shaft 10 to rotate. The rotation of the mounting shaft 10 drives the guiding mechanism 3 through the linkage mechanism 5 to drive the top cloth 9 to slide along the support frame 7 towards the storage box 2. The rotation of the mounting shaft 10 drives the storage cylinder 11 to rotate, and the storage cylinder 11 rotates to wind the top cloth 9 into the storage box 2;

[0049] S2. The driving mechanism 4 rotates, and drives the second pulley 58 and the second bevel gear 557 to rotate together through the mounting shaft 10.

[0050] S3. The rotation of the second bevel gear 557 drives the first bevel gear 556 and the threaded rod 555 to rotate together through meshing. The rotation of the threaded rod 555 drives the trigger block 554 to move through the internal threaded tube 553. The trigger block 554 slides along the adjustment hole 552 and inserts into the adjustment hole 552, driving the connecting rod 551 to slide outwards from the mounting cylinder 51. The sliding of the connecting rod 551 drives the first end face gear 541 to disengage from the second end face gear 542 through the transmission rod 53. After the first end face gear 541 disengages from the second end face gear 542, the driving shaft 31 stops rotating. At this time, the connecting ring 36 just moves to the driving wheel 33, and the driving motor 41 continues to work to drive the storage cylinder 11 to continue rotating to complete the storage of the top cloth 9.

[0051] S4. When the top cloth 9 needs to be unfolded, the driving mechanism 4 rotates in the reverse direction. The storage cylinder 11 first relaxes the top cloth 9 stored on its surface. At this time, the trigger block 554 slides under the cooperation of the first bevel gear 556, the second bevel gear 557, the threaded rod 555 and the internal threaded tube 553 until the first end face gear 541 resets under the action of the return spring 544. The rotation of the driving wheel 33 drives the transmission belt 35 to rotate, which in turn drives one end of the top cloth 9 to slide towards the protective cover 8 until the top cloth 9 is completely unfolded.

[0064] S3. The rotation of the second bevel gear 557 drives the first bevel gear 556 and the threaded rod 555 to rotate together through meshing. The rotation of the threaded rod 555 drives the trigger block 554 to move through the internal threaded tube 553. The trigger block 554 slides along the adjustment hole 552 and inserts into the adjustment hole 552, driving the connecting rod 551 to slide outwards from the installation cylinder 51. The sliding of the connecting rod 551 drives the first end face gear 541 to disengage from the second end face gear 542 through the transmission rod 53. After the first end face gear 541 disengages from the second end face gear 542, the driving shaft 31 stops rotating. At this time, the connecting ring 36 just moves to the driving wheel 33, and the driving motor 41 continues to work to drive the storage cylinder 11 to continue rotating to complete the storage of the top cloth 9.

[0065] S4. When it is necessary to unfold the top cloth 9, the driving motor 41 rotates in the reverse direction. The storage cylinder 11 first relaxes the top cloth 9 stored on its surface. At this time, the trigger block 554 slides under the cooperation of the first bevel gear 556, the second bevel gear 557, the threaded rod 555 and the internal threaded tube 553 until the first end face gear 541 resets under the action of the return spring 544. The rotation of the driving wheel 33 drives the transmission belt 35 to rotate, thereby driving one end of the top cloth 9 to slide towards the protective cover 8 until the top cloth 9 is completely unfolded.

[0066] In the embodiment of the present invention, the driving motor 41 in step S2 has the function of forward and reverse rotation.
