Abstract

The invention relates to an underwater monitoring device for a non-metallic chain mud scraper and a using method thereof. The underwater monitoring device comprises lifting supporting frames assemblies and an automatic control system, wherein the the lifting supporting frames components are horizontally arranged on walls of two sides of a sedimentation tank respectively, and each lifting supporting frame assembly comprises an outer layer tube and an inner layer tube; a scraper capable of horizontally sliding on the lifting supporting frames are arranged on the lifting supporting arranged on two sides; the automatic control system comprises a programmable controller, and a sensing device arranged at the bottom of the sedimentation tank; the sensing device is in data signal connection with the programmable controller to detect the state of the scrapper when the scrapper passes by the sensing device; and the automatic control system further comprises an alarm which is connected with the the programmable controller. The underwater monitoring device has the advantages of being simple in structure, reasonable in design, safe and reliable in working, convenient in operation, high in automation and the like. The underwater monitoring device can reduce work intensities of workers, and controlling operations can be performed timely and effectively when conditions of scraper deflecting, breaking, missing, chain skipping and chain breaking of the scraper are detected to avoid unnecessary losses.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment, in particular to an underwater monitoring device for a non-metallic chain type mud scraper and a method for using the same. Background technique [0002] In the process of urban sewage treatment, the sedimentation tank is one of the basic equipment in the whole treatment equipment. It is mainly used to settle some sludge, mud and sand in sewage treatment. Such sediments need to be scraped off. The shape of the common sedimentation tank also includes various forms, the more common one is the rectangular sedimentation tank. For the scraping equipment, the non-metallic chain type mud scraper is one of the important scraping and skimming equipment in the rectangular sedimentation tank. During daily operation, it is necessary to always pay attention to the operating status of this type of mud scraper, especially when there are situations such as scraper deviation, breakage and missing,...
