Description

Visual detection device for underwater alum flowers Technical Field The utility model belongs to the technical field of sewage treatment and detection, and particularly relates to an underwater alum blossom visual detection device. Background In the sewage treatment process, a flocculating agent is required to be added into the sewage to flocculate and settle insoluble impurities in the sewage. In the process of adding flocculant, the adding amount of flocculant needs to be accurately controlled. In the prior art, a camera is used for shooting a video or an image of alum blossom in a water body, and an image processing technology is used for analyzing the characteristics of the alum blossom, so that the coagulation effect is judged and the adding amount of a flocculating agent is modified. The existing underwater alum blossom shooting device generally adopts a direct light source, and is provided with a reflection light path or a transmission light path for transmitting light rays in cooperation with the direct light source. In the actual shooting process, as the water body contains impurities and a large number of alum flowers, the light rays emitted by the direct light source are not uniformly distributed in the water body, the problems of high brightness of part of the water body and low brightness of part of the water body can occur, and the finally shot image is not clear enough after the unevenly distributed light rays are reflected by the reflecting light path or transmitted by the transmitting light path. In addition, after the photographing lens is attached, impurities in the water body can influence the definition of a final photographed image, so that a final analysis result is inaccurate. Accordingly, the present utility model has been made keeping in mind the above problems occurring in the prior art underwater alum shot apparatuses, and an underwater alum vision inspection apparatus is disclosed. Disclosure of utility model The utility model aims to provide an underwater alum blossom visual detection device which can clearly shoot alum blossom in a water body and remarkably improve the definition of a shot image.
