[0027] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 A waterproof movable cover is suitable for building roof waterproofing, especially for roof waterproofing facilities with indoor sprinkler systems in industrial buildings, including a central cover plate 1, side cover plates 2 are arranged on both sides of the central cover plate 1, a first edge sealing plate 3 is symmetrically arranged below the central cover plate 1, a second edge sealing plate 4 is arranged on one side of the side cover plate 2 facing the central cover plate 1, an L-shaped plate 5 is installed on the second edge sealing plate 4, and two right-angled edges of the L-shaped plate 5 are respectively bonded with sealing heads 6, and bearing plates 7 are symmetrically arranged below the central cover plate 1 and the side cover plates 2, and the bearing plates 7 are arranged on the inspection hole 8.

[0029] Reference Figure 4 A cavity 9 is formed between the L-shaped plate 5 and the first edge sealing plate 3 , and the cavity 9 can accommodate a plugging head 6 , and the plugging head 6 can seal the cavity 9 .

[0030] Reference Figure 1 The width of the side cover plate 2 is greater than that of the center cover plate 1, and the side cover plate 2 extends to the outside of the inspection hole 8. The center cover plate 1 and the side cover plate 2 are 6 mm thick patterned steel plates.

[0031] Reference Figure 3 The bearing plate 7 is arranged on the parallel side of the length direction of the inspection hole 8. The bearing plate 7 is located below the center cover plate 1 and the side cover plate 2 and can simultaneously support the center cover plate 1 and the side cover plate 2 to ensure that the center cover plate 1 and the side cover plate 2 can stably cover the inspection hole 8.

[0032] A plugging head 6 is installed between the bottom wall of the bearing plate 7 and the upper side wall of the inspection hole 8. In this embodiment, the plugging head 6 is made of EPDM material. EPDM is a synthetic rubber material, and its full name is ethylene propylene diene monomer (Ethy l ene Propy l eneDiene Monomer).

[0033] The carrying plate 7 abuts against the ends of the first edge sealing plate 3 and the second edge sealing plate 4 at the same time.

[0034] The height of the first edge sealing plate 3 is smaller than the height of the bearing plate 7 , and the height of the second edge sealing plate 4 is smaller than the height of the bearing plate 7 , so as to ensure the bearing function of the bearing plate 7 .

[0035] A plugging head 6 is installed between the side cover plate 2 and the inspection port. The side cover plate 2 is bonded to the plugging head 6 to form a first waterproof barrier. A groove 10 is opened on the side of the inspection port corresponding to the side cover plate 2 to form a cavity 9 as a second barrier.

The first edge sealing plate 3 and the second edge sealing plate 4 of the present application are set back to back, so that the bottom side plates of the first edge sealing plate 3 and the second edge sealing plate 4 are close to each other, so that a cavity is formed between the bottom side plates.

[0037] Reference Figure 3 The cross section of the bearing plate 7 is set to be L-shaped, and the two right-angled sides of the L-shaped bearing plate 7 can cover the side of the inspection hole 8, ensuring that the bearing plate 7 can be stably placed on the inspection hole 8.

[0038] During the operation process of maintenance, the first step is to open the center cover 1, and the second step is to open the side cover 2. At this point, the inspection hole 8 is fully opened. After maintenance and replacement of equipment components, the first step is to cover the side cover 2, and the second step is to cover the center cover 1. The inspection cover is easy to install and remove.
