DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1-6 The utility model provides a technical solution: a drainage structure for a civil air defense basement, including a sewage collecting box 1, the rear end of the sewage collecting box 1 is fixedly connected to two waterproof seats 13, and a rotating rod 14 is rotatably connected in the two waterproof seats 13. The left and right ends of the rotating rod 14 are fixedly connected to two waterproof rings 15, and the rear end of the sewage collecting box 1 is fixedly connected to the waterproof box 9, and a motor 10 is fixedly connected in the waterproof box 9. The output end of the motor 10 is fixedly connected to a first gear 11, and the right end of the rotating rod 14 is fixedly connected to a second gear 12. The second gear 12 and the first gear 11 are meshed with each other. The circumferential surface of the rotating rod 14 is fixedly connected to a filter collection bar 7, and the filter collection bar 7 is arranged at the upper end of the sewage collecting box 1. This design solves the problem that the original device pushes debris to both sides by a scraper, and the output structure is exposed at the drain outlet, and its screw mechanism will be corroded by sewage, causing its surface to rust, thereby affecting the use effect of the equipment.

[0023] As the first embodiment of the present utility model: the rear end of the sewage collection tank 1 is fixedly connected to a limiting pad 5, and the waterproof ring 15 is made of rubber material. The limiting pad 5 installed at the rear end of the sewage collection tank 1 can be used to limit the filter collection bar 7 to avoid collision with the rear end of the sewage collection tank 1. The waterproof ring 15 is made of rubber and can protect the filter collection bar 7. Two fixed sleeves 2 are fixedly connected to the right end of the sewage collection tank 1. Water pumps 3 are fixedly connected to the two fixed sleeves 2. The upper and lower ends of the water pump 3 are fixedly connected to drain pipes 4, one of which is in communication with the sewage collection tank 1. The fixed sleeve 2 installed at the right end can be used to fix the water pump 3. The drain pipe 4 installed at the upper end of the water pump 3 allows the water pump 3 to discharge the sewage in the sewage collection tank 1 through the drain pipe 4, thereby achieving the purpose of drainage. A limit plate 6 is fixedly connected to the upper end of the filter and collection bar 7, and a sloped seat 8 is fixedly connected to the lower inner wall of the sewage collection tank 1. The limit plate 6, installed on the filter and collection bar 7, traps debris and water within the filter and collection bar 7. The sloped seat 8, installed inside the sewage collection tank 1, drains the sewage from the sewage collection tank 1 into the drain pipe 4. Two positioning blocks 16 are fixedly connected to the front lower end of the filter and collection bar 7. Two positioning slots 17 are defined in the front upper end of the sewage collection tank 1. The two positioning blocks 16 slide into the two positioning slots 17, respectively. The positioning blocks 16 installed at the lower end of the filter and collection bar 7 slide into the positioning slots 17 to retain the filter and collection bar 7 on the surface of the sewage collection tank 1. A filter sleeve 18 is fixedly connected to the junction of the left inner wall of the sewage collection tank 1 and the drain pipe 4. The filter sleeve 18, installed on the inner wall of the sewage collection tank 1, is used to filter the sewage again, thereby achieving effective drainage.

[0024] As a second embodiment of the present utility model: when sewage and debris enter the filter collection bar 7, the sewage will enter the sewage collection box 1, and at the same time the filter collection bar 7 will limit the debris on its surface. By regularly controlling the motor 10 to drive the first gear 11 to rotate, the second gear 12 drives the filter collection bar 7 to rotate toward the rear end, thereby discharging the debris. While reducing the blockage of the filter collection bar 7, it is also convenient for mixing the debris.
