Device and method for automatically cleaning electrolytic bath and automatically preparing and adding liquid

The invention provides a device and a method for automatically cleaning an electrolytic bath and automatically preparing and adding liquid. The device comprises a first circulating pump, a filter, an electrolyte preparation box, a second circulating pump and a control unit, the first circulating pump, the filter, the electrolyte preparation box and the second circulating pump are sequentially communicated through pipelines; and the control unit is respectively in electric signal connection with the first circulating pump, the electrolyte preparation box and the second circulating pump. The cleaning degree of the electrolyte in the electrolytic cell is kept, the automation degree of electrolytic cell purification and electrolyte preparation is improved, the disassembly and assembly frequency of the water electrolysis hydrogen production electrolytic cell is reduced, and the stability of the electrolytic cell of the water electrolysis hydrogen production equipment is improved. 本发明提供一种自动清洗电解槽及自动配液加液的装置及方法，该装置包括第
