Furthermore, the top of the vertical section of the door body, which is perpendicular to the water stop surface, is of a ladder-shaped structure. When the door body is pulled upwards by the opening and closing device, the roller is close to one side of the back of the water stop surface, if the roller is directly lifted, the roller can be clamped on the upper edge of the door body, the inclined surface plays a transition role, and the roller firstly rolls on the inclined surface and then rolls to the side surface of the door body.
Furthermore, a plurality of reinforcing ribs are arranged on the water stop surface. The strengthening rib can increase the intensity of the door body, makes the door body when bearing great water pressure, is difficult for taking place deformation.
Furthermore, the pressing block is a wedge-shaped block with a thin upper part and a thick lower part, the bump is a wedge-shaped block with a thick upper part and a thin lower part, and the inclined surfaces of the pressing block and the bump are completely attached. When the door body is inserted into the bottom of the guide rail, the convex block is attached to the inclined plane of the pressing block, and the pressing block presses the convex block, so that the back of the water stop surface of the door body is tightly attached to the frame body, and the sealing effect is achieved.
The utility model has the beneficial effects that:
1. according to the utility model, the first roller and the second roller are added, so that rolling friction is realized between the door body and the guide rail, the abrasion between the door body and the guide rail is reduced, the guide rail is not easy to deform, and the sealing performance of the gate is better.
2. When the door body moves up and down, the brush can clean garbage in the guide rail, and the door body is prevented from moving up and down and being blocked.
3. The reinforcing ribs can increase the strength of the door body, so that the door body is not easy to deform when bearing high water pressure.
