Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example 1: A sludge scraping device for sewage treatment, see reference Figures 1-5 As shown, the system includes a base frame 1, an electric slide rail 2, an electric slider 3, and a first scraper 4. The electric slide rail 2 is bolted to the middle of the base frame 1. Electric sliders 3 are installed on both the left and right sides of the electric slide rail 2, and both electric sliders 3 slide on the electric slide rail 2. The first scraper 4 is installed on the electric slider 3. The system also includes a support frame 5, an electric push rod 6, a lifting frame 7, a support plate 13, a connecting pipe 14, a nozzle 15, and an external connecting pipe 16. The support frame 5 is welded to the middle of the base frame 1. The electric push rod 6 is bolted to the top of the support frame 5. The lifting frame 7 is installed on the telescopic rod of the electric push rod 6. The support plate 13 is symmetrically fixed to the top of the lifting frame 7. The connecting pipe 14 is connected to the lower part of the support plate 13. Multiple nozzles 15 are connected to both the left and right sides of the connecting pipe 14. The external connecting pipe 16 is connected to the top of the connecting pipe 14.

[0022] See Figure 1 As shown, it also includes a protective shell 12. The protective shell 12 is installed in the middle of the support frame 5 by welding, and the electric push rod 6 is located inside the protective shell 12.

[0023] See Figure 5 As shown, it also includes a protective net 17, which is installed inside the nozzle 15.

[0024] When cleaning the sewage tank is required, the equipment is placed at the bottom of the sewage tank, and the external water pipe is connected to the external connecting pipe 16. When the first scraper 4 contacts the bottom of the sewage tank, the electric slide rail 2 is activated, causing the electric slide rail 2 to drive the two electric sliders 3 to move inward. Simultaneously, the electric sliders 3 move, driving the first scraper 4 to move, thus scraping the sludge from the bottom of the sewage tank. After scraping, the electric slide rail 2 is closed, and water is injected into the external connecting pipe 16 through the external water pipe, causing water to spray out from the nozzle 15 on the connecting pipe 14. Then, the electric push rod 6 is activated. The protective shell 12 protects the electric push rod 6 from electrical shock. If the electric push rod 6 is damaged due to external factors, the extension and retraction of the electric push rod 6 will cause the lifting frame 7, support plate 13 and connecting pipe 14 to move up and down, thereby automatically cleaning the sewage tank and ensuring that the water flow can reach every corner of the sewage tank to ensure cleaning quality. After cleaning, stop injecting water into the external pipe 16. When the sewage tank needs to be disinfected later, disinfectant water can be injected into the external pipe 16. Repeating the above operation can automatically carry out sewage tank disinfection. The protective net 17 can prevent mud and dirt from clogging the nozzle 15, and the fixing ring 18 can fix and limit the connecting pipe 14.

[0025] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a collection plate 9, a limiting ring 10, and a connecting rod 11. Four connecting rods 11 are fixedly connected at even intervals on the top of the lifting frame 7. The connecting rods 11 are slidably provided with limiting rings 10. The collection plate 9 is fixedly connected between the four limiting rings 10. The collection plate 9 is in contact with the second scraper 8.

[0026] See Figures 2-4 As shown, it also includes a second scraper 8. The lower part of the lifting frame 7 is fixedly connected to the second scraper 8. The second scraper 8 is rectangular in shape and can completely fit the inner wall of the sewage tank. The support plate 13 and the connecting rod 11 are located inside the second scraper 8.

[0027] See Figure 4 As shown, it also includes fixing rings 18. Two sets of fixing rings 18 are fixedly connected at even intervals on the support plate 13. The connecting pipe 14 is located in the two sets of fixing rings 18 that are close to each other. Each set of fixing rings 18 has two rings.

[0028] When it is necessary to scrape the sludge from the inner wall of the sewage tank, the electric push rod 6 is activated. The extension and retraction of the electric push rod 6 drives the lifting frame 7, connecting rod 11 and second scraper 8 to move up and down, so that the second scraper 8 scrapes the sludge from the inner wall of the sewage tank, which improves the cleaning effect and efficiency of the sewage tank. The scraped sludge is stored on the collection plate 9 for easy cleaning. After the sludge scraping is completed, the electric push rod 6 is turned off and the sludge on the collection plate 9 is cleaned.
