The invention discloses a pipeline inner wall washing device with a self-cleaning function. The pipeline inner wall washing device comprises an adjusting disc, a rotary disc, a pipe inner wall, holes,guide pipes, magnetic blocks, a hard brush device, a soft brush device, driving shafts, a water inflow pipe, water injection nozzles, a pipe inner wall, connecting rods and locking grooves. Various kinds of dirt can be more pertinently and completely cleaned away at a time in the manner of sequential washing of hard brushes and soft brushes, washing brush heads of the washing device do not need to be specially taken out, simplicity and convenience are achieved, the clean brush heads stretch out in the next conversion process after the brush heads are self-cleaned, new washing is carried out,thus, the problem that the brush heads with dirt are poor in washing effect after being used for a long time can be avoided, and more convenient self-washing of the brush heads is also achieved whilethe washing effect is enhanced.

The invention discloses a pipeline inner wall cleaning device. The pipeline inner wall cleaning device comprises an adjusting disc, a rotating disc, a pipe inner wall, holes, guiding pipes, rotating rods, a hard hairbrush device, a soft hairbrush device, a driving shaft, a water inlet pipe, water spray mouths, the pipe inner wall, a connection rod and a locking groove. According to the pipeline inner wall cleaning device, by means of the manner that a hard hairbrush and a soft hairbrush perform cleaning in sequence, all kinds of dirt can be thoroughly removed at a time with more pertinence, various cleaning processes are finished on one cleaning structure, cleaning is performed thoroughly and completely, and complex procedures of the routine cleaning process are avoided, operation workingprocedures are saved, the whole pipeline inner wall cleaning device is simple in structure and convenient to use, the cleaning process is convenient to operate utilizing the cleaning structure, by means of the arrangements of a switching blocking rod and a plurality of clamping grooves, switching of the extension length of the hairbrushes can be realized, the fact that the suitable and thorough cleaning method and cleaning sequence are selected more freely can be realized according to actual pipelines and different types of media inside the pipelines, and the universality of the cleaning device is improved.

The object of the present invention is to provide a novel cyclase whose amino acid sequence is SEQ ID NO:1.
