[0004] The Chinese invention patent with the application number 201210550000.X and the name "a sludge washing gun with a multi-nozzle structure" discloses a washing gun with three washing directions, but it can be seen from the disclosed content that The oblique nozzle assembly of the flushing gun is only arranged on one side, which cannot meet the requirements of nozzles arranged on both sides and the rotation direction of the nozzles on both sides are consistent. At the same time, it is not clear how to realize the transmission between the motor and the gear shaft and the arrangement and arrangement of the water channel in the patent. circulation design
Those skilled in the art cannot realize the flushing mechanism design of the multi-angle bilateral asymmetrically arranged nozzles according to the disclosed content

Description
technical field [0001] The invention relates to the technical field of steam generator cleaning, in particular to a steam generator cleaning device suitable for multi-directional jets in a narrow space. Background technique [0002] The steam generator is an important equipment used for heat exchange in the primary and secondary circuits of a nuclear power plant. There are as many as tens of thousands of tube bundles installed inside. Every time a nuclear power plant is shut down for maintenance, it is necessary to clean the secondary side tube bundle of the steam generator. With the third-generation nuclear power technology steam generator put into use, the development of its cleaning technology and equipment is also necessary. For example, the internal structure of the third-generation steam generator designed by B&W Company is quite special. The heat transfer tubes are arranged in an equilateral triangle. In the case of the parameters and straightness of the jet, the sy...
