DETAILED DESCRIPTION

[0013] As shown in the accompanying drawings, the present embodiment provides an embedded permanent magnet installation system for a permanent magnet rotor of a submersible motor, including a rotor bracket 1 for fixing a permanent magnet rotor 2, a permanent magnet 3 transmission mechanism is arranged above the rotor bracket 1, and the permanent magnet 3 transmission mechanism coaxially places a plurality of permanent magnets 3 in parallel, and the permanent magnet 3 transmission mechanism can drive the permanent magnet 3 to move axially, keeping the permanent magnet 3 at the end corresponding to the position where the permanent magnet 3 is installed on the permanent magnet rotor 2.

[0014] As shown in the figure, the permanent magnet 3 conveying mechanism includes a conveying frame 5, a conveying motor 6, a lead screw guide rail 7, and a guide block pusher 8. The conveying motor 6 is fixed on the conveying frame 5 and connected to the lead screw guide rail 7, driving the lead screw guide rail 7 to transfer, and the guide block pusher 8 is threadedly matched with the lead screw guide rail 7 and contacts the side of the permanent magnet 3 at the inner end, and the guide block pusher 8 is moved by the rotation of the lead screw guide rail 7, and the guide block pusher 8 can push all the permanent magnets 3 to move.

[0015] In addition, the transmission motor 6, the lead screw guide rail 7, and the guide block pusher 8 on the transmission mechanism of the permanent magnet 3 can also be replaced by a hydraulic cylinder, and the entire permanent magnet 3 can be pushed to move by extending and retracting the cylinder rod of the hydraulic cylinder.

[0016] A permanent magnet 3 installation mechanism is arranged above the permanent magnet 3 transmission mechanism, and the lower end of the permanent magnet 3 installation mechanism corresponds to the permanent magnet 3 at the outer end, and can press the permanent magnet 3 at the outer end into the permanent magnet rotor 2. When the permanent magnet 3 at the outer end is pressed into the permanent magnet rotor 2, the permanent magnet 3 transmission mechanism pushes the remaining permanent magnets 3 to move, keeping the next permanent magnet 3 in the installation position at the outer end.
