The first gear 701 is fixedly connected to one end of the first guide rod 14, and the second gear 702 is fixedly connected to one end of the second guide rod 15. The third screw rod 703 is rotatably connected to the front side of the support plate 11, and a toothed plate 705 slidably connected to the outside of the support plate 11 is screw-connected to the outside of the third screw rod 703.

A second drive motor 704 is connected to one end of the third screw rod 703, and the second drive motor 704 is fixedly connected to the front side of the support plate 11 to drive the third screw rod 703 to rotate forward and backward.

[0020] By providing the first gear 701, the second gear 702, and the toothed plate 705, 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. When the toothed plate 705 moves, the internal racks move the first gear 701 and the second gear 702 to achieve relative direction and synchronous rotation. Meanwhile, the first inclined plate 16 and the second inclined plate 17 automatically open or close within the support plate 11, facilitating the discharge of soil and sand accumulated inside.

[0021] A second inclined plate 17 is connected to the outside of the first guide rod 14, and a first inclined plate 16 is connected to the outside of the second guide rod 15.

Therefore, the regulating block 801 and the regulating groove 18 play a certain positioning role in the connection to the support plate 11, preventing the position of the support plate 11 from shifting when the support plate 11 is fixed to the first connecting block 9 and the second connecting block 10, and ensuring the stability effect after the support plate 11 is fixed.

[0023] The auxiliary mechanism 6 includes a first threaded rod 601, a second threaded rod 602, a first drive motor 603, and a drainage pipe 604.

By providing the drainage pipe 604 and the movable pipe 605, when the first connecting block 9 is affected by the thrust of the second movable plate 5, the movable pipe 605 slides within the drainage pipe 604, thereby discharging water accumulated in the subway construction pits at different heights and improving the drainage effect of the support protection device.

[0024] A second connecting block 10 is connected to the other side of the support plate 11, an auxiliary block 12 is connected below the support plate 11, and a connecting plate 13 is connected to the outside of the auxiliary block 12, and the auxiliary block 12 is connected to the first movable plate 4 via the connecting plate 13. A first screw rod 601 is rotatably connected to one side of the first sleeve plate 2, and a second screw rod 602 is rotatably connected to one side of the second sleeve plate 3. A first drive motor 603 is fixedly connected to the outside of the second sleeve plate 3, and the output shaft of the first drive motor 603 is connected to the second screw rod 602.

[0025] By providing the auxiliary block 12 and the connecting plate 13, when the support plate 11 is fixedly connected within the first connecting block 9 and the second connecting block 10, the auxiliary block 12 below the support plate 11 is connected to the corresponding first movable plate 4 and second movable plate 5 via the connecting plate 13. Then, the auxiliary block 12 and the connecting plate 13 improve the stability of the support plate 11 after fixing, and can improve the load-bearing capacity and deformation-resistant capacity of the support plate 11.

[0026] The first screw rod 601 is connected to the second screw rod 602 via an anti-slip belt 606, and the first movable plate 4 is screw-connected to the outside of the second screw rod 602. By providing the anti-slip belt 606, when the first drive motor 603 drives the second screw rod 602 to rotate, the first screw rod 601 rotates in synchronization with the second screw rod 602 via the anti-slip belt 606, thereby realizing the function of the first movable plate 4 and the second movable plate 5 to move uniformly and preventing the first movable plate 4 and the second movable plate 5 from shifting position during movement.

[0027] The second movable plate 5 is screw-connected to the outside of the first screw rod 601, the drain pipe 604 is fixedly connected to the other side of the first fitting plate 2, and the movable pipe 605 is fixedly connected within the first connecting block 9.

[0028] By providing the filter disc 607, when this support protection device discharges the water accumulated at the top, the accumulated water flows into the corresponding movable pipe 605 through the first inclined plate 16 and the second inclined plate 17, respectively, and the filter disc 607 in the movable pipe 605 filters the accumulated water, preventing the sediment in the accumulated water from being discharged through the movable pipe 605, avoiding clogging of the inside of the movable pipe 605 with sediment and reducing the subsequent operating procedures.

[0029] The operating principle and usage flow of this utility model are as follows: When this support protection device is used, 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 blocks 801 on the sides of the support plate 11 engage with the restricting grooves 18 to rotate the rotating plate 803 within the fixed sleeve 802, and when the rotating plate 803 overlaps the upper part of the mounting plate 804, it also engages with the restricting blocks 801, after which the end of the rotating plate 803 is screw-connected to the mounting plate 804 via bolts 805. The support plate 11 is connected to the second connecting block 10 using the above configuration, and then the auxiliary blocks 12 below the support plate 11 are connected to the first movable plate 4 and the second movable plate 5 via connecting plates 13, respectively.

[0030] When support treatment is required after the support plate 11 has been connected, the second screw rod 602 is driven to rotate via the first drive motor 603, and the first screw rod 601 rotates synchronously 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. As the first movable plate 4 and the second movable plate 5 move, the movable pipe 605 slides within the drain pipe 604, allowing the support plate 11 to be adjusted to an appropriate position. When water accumulated on the top of this support protection device needs to be drained, 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 discs 607 in the movable pipes 605.

[0031] When debris inside the support plate 11 needs to be cleaned, the second driving 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 debris inside the first inclined plate 16 and the second inclined plate 17 naturally falls along the inclination angle.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is limited by the appended claims and their equivalents. [Explanation of symbols]
