A screw 28 is installed on the inner surface of the connecting plate 26, and a nut 29 is installed on the surface of the screw 28. Under the action of the support rod 2, the drainage cover plate 11 is supported, so as to facilitate the operator to handle the drainage channel below the mounting base 1.

[0029] Furthermore, two groups of support rods 2 are provided, and the two groups of support rods 2 are movably connected to the two sides of the drainage cover plate 11. The support rods 2 are rotatably connected to the surface of the connecting block 23 through the first rotating groove 22. The cross-section of the connecting block 23 is "I"-shaped, and the limit block 21 is snap-connected to the surface of the limit groove. Under the action of the first rotating groove 22, the support rods 2 rotate around the connecting block 23 as the center.

[0030] Furthermore, the surface of the limit groove is "L"-shaped, and two groups of fixed plates 24 and mounting blocks 27 are provided. The two groups of fixed plates 24 are fixedly connected to the two sides of the mounting base 1, and the two groups of mounting blocks 27 are arranged on the two groups of connecting plates 26. Through the connection between the limit blocks 21 and the limit grooves at different positions, different angles of limitation are formed for the drainage cover plate 11 after rotation.

[0031] Furthermore, the screw 28 penetrates and is connected to the surface of the connecting plate 26 and the mounting block 27, and two groups of nuts 29 are provided. The two groups of nuts 29 are connected to the two ends of the screw 28 through threads, and the nuts 29 are abutted and connected to the surface of the mounting block 27.

[0032] Furthermore, a warning mechanism is provided on the surface of the mounting base 1, and the warning mechanism includes a first connecting rod 3, which is movably connected to the surface of the mounting base 1, a storage groove 31 is provided on the surface of the mounting base 1, a second rotating block 32 is fixedly connected to the surface of the storage groove 31, a second connecting rod 33 is movably connected to the surface of the storage groove 31, a second rotating groove 34 is provided on the surface of the second connecting rod 33, a sliding block 35 is fixedly connected to the surface of the second connecting rod 33, a sliding groove 36 is provided inside the first connecting rod 3, and the length of the first connecting rod 3 is greater than the total length of the two groups of second connecting rods 33.

[0033] Furthermore, two groups of storage slots 31 are provided, and the two groups of storage slots 31 are opened on both sides of the mounting base 1. Two groups of second rotating blocks 32 and second connecting rods 33 are provided, and the two groups of second rotating blocks 32 are fixedly connected to the two sides of the storage slots 31.

Under the connection between the sliding block 35 and the sliding groove 36, the connection between the second connecting rod 33 and the first connecting rod 3 is realized, so that the warning mechanism after opening forms a warning sign to remind pedestrians.

[0035] Working principle: When installing the drain cover 11, first place the two sets of mounting blocks 27 on both sides of the connecting plate 26 so that the inner surface holes of the connecting plate 26 and the mounting blocks 27 are aligned. At this time, insert the screw 28 into its inner surface, and install the nut 29 on the screw 28 under the action of the thread. When opening, rotate the drain cover 11 around the screw 28, and rotate the support rods 2 on both sides around their respective connecting blocks 23. The limit blocks 21 slide along the limit grooves on the fixing plate 24 and finally engage with them, so that a certain angle is formed between the drain cover 11 and the mounting base 1.

[0036] When the drain cover is damaged, first pull the first connecting rod 3 upward to drive the movement of the second connecting rod 33, so that the second connecting rod 33 rotates around the second rotating block 32, and the sliding block 35 slides on the slide groove 36. When pulled to the highest point, the two groups of second connecting rods 33 continue to rotate toward the two sides of the mounting base 1, so that the first connecting rod 3 and the two groups of second connecting rods 33 form an inverted trapezoid with the mounting base 1, thereby playing the role of warning pedestrians.
