A driving component for driving the worm 10 to rotate is installed inside the active slewing reducer 1 and the driven slewing reducer 2.

[0024] When the device is in use, the driving motor 31 outputs torque to rotate the active transmission shaft 7, and the active transmission shaft 7 is connected to rotate the driven transmission shaft 8 through the torque overload protection component, and the inside of the active rotary reducer 1 and the driven rotary reducer 2 drives the worm 10 to rotate through the driving component, and then the worm 10 rotates the worm wheel 4, so that the device can realize multi-point rotation through a single set of motor parallel shaft input, which is suitable for photovoltaic panel systems.

[0025] The torque overload protection assembly includes a first connecting rod 22 and a second connecting rod 23.

When the torque overload protection component is in use, when the output torque of the driving motor 31 is normal, the connecting sleeve 24 pushes against the second connecting rod 23 under the action of the spring 29, so that the first limiting rod 27 on the second connecting rod 23 is stuck in the groove 26, and the second limiting rod 28 on the first connecting rod 22 is stuck in the short side of the L-shaped groove 25, thereby limiting the synchronous rotation of the first connecting rod 22 and the second connecting rod 23. When the torque of the driving motor 31 is too large due to an emergency, under the action of the large torque, the first limiting rod 27 on the second connecting rod 23 is disengaged from the groove 26, thereby pushing the connecting sleeve 24 to move toward the first connecting rod 22, so that the second limiting rod 28 is stuck in the long side of the L-shaped groove 25, so that the first connecting rod 22 and the second connecting rod 23 are disengaged from the limit, so that the driving motor 31 restores normal torque, avoiding large torque causing The driving motor 31 is overloaded and damaged. After the problem is solved by the staff, the second limit rod 28 and the first limit rod 27 are continued to be stuck in the short sides of the groove 26 and the L-shaped groove 25 respectively, so that they can rotate synchronously. The interior of the active rotary reducer 1 and the driven rotary reducer 2 are rotated by the meshing of the second bevel gear 17 and the first bevel gear 16 on the rotating rod 19, and then the rotating tube 11 is rotated by the meshing of the first gear 20 and the second gear 21, so that the worm 10 on the rotating tube 11 is rotated, and then the worm wheel 4 is rotated by the worm 10, so that the device can realize multi-point rotation through a single set of motor parallel shaft input, which is suitable for photovoltaic panel systems. In addition, the device is realized by sleeve-mounting the worm 10 on the rotating tube 11, and the two sides of the rotating tube 11 are connected to the outside of the vent through the vent holes 14 on the mounting block 12, so that the outside wind can blow into the rotating tube 10 to take away the heat generated by the worm wheel 4 and the worm 11 when working, and a ventilation dustproof plate 6 is set at the vent to prevent dust and debris from entering.
