[0031] The working principle of the utility model is as follows: the foam cleaning device for sewage treatment pool is additionally provided with a scraping mechanism 3 and a spraying mechanism 4. Before using the foam cleaning device for sewage treatment pool, it is necessary to pre-connect the hydraulic cylinder 301 and the driving motor 314 to electricity and connect to the control terminal, and it is also necessary to pre-connect the discharge pipe 316 to the external liquid collecting bin, and connect the first injection pipe 402 and the second injection pipe 405 to the external injection pump to ensure the stability of the infusion; when using the foam cleaning device for sewage treatment pool, firstly, the device is installed as a whole in the sewage treatment system, and when a large amount of sediment and foam are accumulated, the scraping mechanism 3 and the spraying mechanism 4 are activated. When the spraying mechanism 4 is activated, the external injection pump injects defoaming agent into the first spraying pipe 401 and the second spraying pipe 404, and the defoaming agent is evenly sprayed downward through the nozzle 403, thereby eliminating the foam. At the same time, the scraping mechanism 3 is activated, and the driving motor 314 is started to drive the threaded rod 308 to rotate, which can drive The displacement slider 307 and the hydraulic cylinder 301, docking plate 302, lower pressure plate 303, spring body 304, scraper body 305 and scraping razor 306 below the displacement slider 307 move synchronously. When the scraping razor 306 moves, the scraping razor 306 can remove the sediment and foam at the bottom of the pool. When the scraping razor 306 moves, the hydraulic cylinder 301 is started to push the docking plate 302, the lower pressure plate 303, the spring body 304, the scraper body 305 and the scraping razor 306 downward, which can increase the downward force and thus scrape off the sediment and foam at the bottom of the pool. In summary, the scraping mechanism 3 adopts an adjustable scraping structure, which can quickly scrape off the sediment and foam at the bottom of the sewage treatment tank body 1. The slope structure adopted by the sewage treatment tank body 1 is convenient for cleaning the sediment and foam, and the cleaning efficiency is higher. The liquid spraying mechanism 4 is used to cooperate with the scraping mechanism 3 to perform cleaning operations, and spray the defoaming agent to quickly eliminate the foam.
