In order to improve the structural strength and stability, a partition bar is provided on the inner wall of the first-layer annular wall 4, and an end cover 5 is fixed to the outer end of the first-layer annular wall 4 by bolts. The cross-section of the end cover 5 is I-shaped, and the inner disk of the end cover 5 is connected to the second-layer annular wall 7 to form a multi-layer protective cover. Through the above-mentioned split design, targeted maintenance can be performed after wear and tear, saving maintenance costs.

[0029] As an implementation method in this embodiment, the positioning component: four groups of positioning blocks 8 are provided on the flange of the motor body 1, and the positioning blocks 8 are arranged in a ring array. A group of inner ring channels 401 are provided on the inner wall of the ring platform of the first ring wall 4, and an inlet channel 400 connected to the outside is provided on the inner wall of the inner ring channel 401. There are four groups of inlet channels 400, and a group of positioning holes 402 (the cross section of the positioning holes 402 is T-shaped) connected to the inner ring channels 401 are provided between two adjacent inlet channels 400, and a group of positioning pins 9 with a T-shaped cross section are slidably connected in the positioning holes 402.

Under the connection of the connecting bolt 12, the second layer of the ring wall 7 rotates along with the first layer of the ring wall 4. During the rotation, the fixed head 6 slides in the sliding hole 201 of the limit block 2, so that the fixed head 6 slides to the position of the plug hole 200 (during the above sliding process, the positioning block 8 on the flange is separated from the positioning pin 9 of the positioning hole 402, the positioning pin 9 slides in the groove of the positioning block 8, and squeezes the spring 11 installed between the lock head 10. After the limit is released, under the action of the spring 11, the positioning pin 9 is reset again, and then the positioning block 8 slides in the inner annular channel 401 and moves to the position of the inlet channel 400), and then the protective cover is pulled backward to release the connection between the first layer of the ring wall 4 and the plug hole 200, and the positioning block 8 is moved out from the inlet channel 400;

[0032] After completing the above operations, remove the end cover 5 and observe the status of the first layer of the ring wall 4 and the second layer of the ring wall 7. If one of the groups needs to be replaced, remove the connecting bolt 12 on the ring edge 700 and remove the connecting bolt 12 from the through hole 701 of the ring edge 700. In this process, the connection between the connecting bolt 12 and the connecting hole 403 is released, so as to perform maintenance or replacement. Subsequently, operate in the direction, assemble the above-mentioned protective covers together, and install them back.
