The working principle and usage flow of this utility model are as follows:
When using this support protection device, both sides of the support plate 11 can be connected to the first connecting block 9 and the second connecting block 10, respectively, and the restricting block 801 on the side of the support plate 11 engages with the restricting groove 18 to rotate the rotating plate 803 in the fixed sleeve 802, and when the rotating plate 803 overlaps above the mounting plate 804, it also engages with the restricting block 801, and then the end of the rotating plate 803 is screwed to the mounting plate 804 via the bolt 805. The support plate 11 is connected to the second connecting block 10 using the above-mentioned form, and then the auxiliary block 12 below the support plate 11 is connected to the first movable plate 4 and the second movable plate 5 via the connecting plate 13, respectively.

When support processing is required after the connection of the support plate 11 is completed, the second screw rod 602 is driven to rotate via the first drive motor 603, and the first screw rod 601 rotates in synchronization with the second screw rod 602 via the anti-slip belt 606. The first movable plate 4 moves on the surface of the second screw rod 602, while the second movable plate 5 moves on the surface of the first screw rod 601. When the first movable plate 4 and the second movable plate 5 move, the movable pipe 605 slides in the drain pipe 604, and the support plate 11 can be adjusted to an appropriate position. When draining water accumulated at the top of this support protection device, the accumulated water flows into the corresponding movable pipes 605 through the first inclined plate 16 and the second inclined plate 17. The accumulated water is filtered by the filter disk 607 in this movable pipe 605.

When it is necessary to clean the debris inside the support plate 11, the second drive motor 704 drives and rotates the third screw rod 703, while the toothed plate 705 moves on the surface of the third screw rod 703. Racks are opened on both the upper and lower sides inside the toothed plate 705, and the toothed plate 705 meshes with the first gear 701 and the second gear 702, respectively, so that the first guide rod 14 and the second guide rod 15 rotate relative to each other, and the first inclined plate 16 and the second inclined plate 17 unfold after rotating relative to each other, so that the debris inside the first inclined plate 16 and the second inclined plate 17 naturally falls along the inclination angle.
