According to the present invention, disclosed is a manhole cleaning apparatus. If a wastewater absorption body absorbs wastewater from a manhole, a wastewater storage part on one side in a storage tank first stores the absorbed wastewater and the wastewater stored in the wastewater storage part is discharged to a cyclone filter part, a disc filter part, a first filtration filter part, a second filtration filter part and a third filtration filter part stage by stage. The wastewater is filtered five times during the procedure of staged discharge with the cyclone filter part, the disc filter part, the first filtration filter part, the second filtration filter part and the third filtration filter parts, so purified water can be obtained. The purified water is stored in a purified water storage part installed on the other side in the storage tank, and then, the stored purified water is sprayed to the manhole with high pressure to clean the inside of the manhole, so the use of water for cleaning the manhole can be minimized. Moreover, since an absorption pump and an absorption and discharge pump are operated at the same time when the wastewater absorption body absorbs the wastewater from the manhole, time for the absorption of the wastewater can be considerably shortened, and also, the wastewater stored in the wastewater storage part can be quickly discharged by the absorption and discharge pump after the completion of the manhole cleaning work, so workability and efficiency can be significantly increased.
본 발명은 맨홀측으로부터 흡입된 오수를 오수흡입체가 흡입하면 흡입된 오수를 저장탱크 내부 일측에 구비된 오수저장부가 먼저 저장하고 오수저장부에 저장된 오수를 싸이클론필터부와 디스크필터부, 제1여과필터부, 제2여과필터부, 제3여과필터부측으로 단계별로 배출시키고 싸이클론필터부와 디스크필터부, 제1여과필터부, 제2여과필터부, 제3여과필터부에 의해 단계별로 배출되는 과정에서 오수가 5차에 걸쳐 여과되도록 하여 정수를 얻을 수 있도록 하고, 얻어진 정수를 저장탱크 내부 타측에 구비된 정수저장부에 저장한 후 저장된 정수를 다시 맨홀측으로 고압분사하여 맨홀 내부를 세척하도록 함에 따라 맨홀 세척작업 시에 세척수 사용을 최소화할 수 있으며, 오수흡입체에 의해 맨홀 내부 오수가 흡입될 때 흡입펌프와 흡입배출펌프가 동시에 가동되어 호수의 흡입시간을 크게 단축함은 물론 맨홀 세척 작업 완료 후 흡입배출펌프에 의해 오수저장부에 저장된 오수를 빠르게 배출할 수 있어 작업성 및 작업효율성을 크게 향상시킬 수 있는 맨홀 청소차량이 개시된다.
