The application discloses a floating photovoltaic power generation device suitable for fish culture, which comprises a corrosion-resistant floating body, a power generation module, a sun tracking module and a self-cleaning module integrated on the floating body to form an integrated independent power supply unit, and photovoltaic panels replace high-voltage power transmission to supply power to the culture device; the sun tracking module realizes sun tracking of the photovoltaic panels through a two-degree-of-freedom deflection structure combined with intelligent control and takes into account underwater culture illumination; the self-cleaning module realizes automatic cleaning of the photovoltaic panels through cooperation of a brush / roller brush and spraying; the floating body can be used alone or composed of a power generation group, and is matched with structures such as buoyancy reinforcement, gravity center lowering and wind and wave resistance linkage, and is suitable for different scales and types of culture water areas. The application realizes on-site power consumption, eliminates hidden dangers of high-voltage power transmission, improves photovoltaic power generation efficiency, reduces operation and maintenance cost, takes into account power generation and culture ecology, and has high practicability.

This invention relates to a method for sealing beryllium foil and stainless steel components, comprising the following steps: S1, pretreatment: the beryllium foil is degreased and acid-washed to remove surface oil and oxides; the stainless steel components and solder are pretreated, including degreasing and cleaning, to remove surface oil; S2, assembly: the beryllium foil, solder, and stainless steel components are assembled sequentially from bottom to top to obtain an assembled component to be brazed; S3, brazing: the assembled component is placed in a vacuum furnace, the furnace temperature is increased and maintained, and the oxides on the beryllium foil are decomposed by high temperature, allowing the solder to effectively wet the beryllium foil and react fully and effectively. After the heat preservation is completed, the temperature is controlled to drop to room temperature, and the brazed sealed component is removed. The beryllium foil and stainless steel component sealing method of this invention can effectively remove oxides from the surface of the beryllium foil, and the solder has good wettability to the stainless steel component, reacting directly to achieve welding between the beryllium foil and the stainless steel component, resulting in a high-quality beryllium foil and stainless steel component sealing component.
