This invention relates to the field of black-spotted catfish farming technology, and in particular to a method and apparatus for black-spotted catfish farming. The apparatus includes a farming pond, a sludge treatment component, a temperature control module, a drive component, and a heat-insulating shed component. The sludge treatment component is fixedly connected to the farming pond, and the temperature control module is fixedly connected to the inner wall of the farming pond. The catfish are placed in the farming pond for farming, and the temperature is controlled at 8℃-9℃ by the temperature control module. When a large amount of fish excrement and debris is generated at the bottom of the pond, the drive component activates the sludge treatment component to collect and clean the sludge and clean the hourglass farming plate, preventing blockage of the hourglass farming plate and avoiding water quality issues and fish diseases. When the weather is cold or too hot, or when the temperature exceeds the minimum and maximum thresholds, the temperature control module activates the heat-insulating shed component to maintain a stable water temperature in the farming pond and ensure an optimal farming environment.

The utility model discloses an ultrasonic cleaning machine for parts, and belongs to the technical field of ultrasonic cleaning machines. Comprising a main body frame, and a cleaning device is connected in the main body frame. The connecting rods are fixedly connected with the inner side of the main body frame, and the other ends of the connecting rods are fixedly connected with the first frame body. The ultrasonic generator is fixedly connected with the bottom of the first frame body, the turbine is fixedly connected with the side face of the first frame body, and one end of the traction rope is fixedly connected with the second frame body. A cleaning device is connected to the bottom of the main body frame, a discharging opening is formed in the side face of the lower portion of the main body frame, and a blocking door is hinged to the discharging opening. The problems that after parts are cleaned through an existing ultrasonic cleaning frame, impurities and oil stains are prone to being accumulated at the bottom of the cleaning frame, cleaning is difficult, and water is turbid are solved.

The invention relates to the related technical field of culture systems, in particular to a solar temperature control aquaculture system which comprises a base, a deepwater area water tank, a shoal area water tank, an overturning support assembly, a solar panel, a collecting and releasing box, a three-composite film, a water oxygenation circulation assembly and an algae discharging assembly. A semicircular plate and a transparent cover are installed on the top of a water tank in the deep water area. The overturning support assembly drives the solar panel to move. The two collecting and releasing boxes are connected with the two ends of the three-in-one film correspondingly, and all-weather precise temperature control is achieved by collecting and releasing the light-transmitting film, the reflecting film and the heat preservation film. The two ends of the water oxygenation circulation assembly are connected with the bottoms of the shoal area water tank and the deep water area water tank correspondingly, and unpowered water circulation oxygenation is achieved through the air stripping principle. The algae discharging assembly is matched with a slope at the bottom of the shoal area water tank, and dead algae are automatically conveyed to the deep water area water tank to be used as bait. According to the invention, illumination dynamic regulation and control, water body self-circulation oxygenation and dead algae automatic cleaning are realized, and energy consumption and culture risks are obviously reduced.
