The application discloses a floating fish-light complementary system, which comprises a support unit, a photovoltaic assembly fixed on the support unit, a net cage, a net-retrieving assembly, and a sinker. The net cage comprises a floatable float located at the upper end of the net cage and connected with the support unit, a sinker located at the lower end of the net cage and extending around the central axis of the net cage, and a net cover covering at least the bottom and the side wall of the net cage. The net-retrieving assembly comprises a plurality of second pull ropes distributed along the circumferential direction of the net cage, the second pull ropes being connected with the sinker and a first rope-retrieving device arranged at the upper end of the net cage and capable of pulling the second pull ropes. The application provides a floating fish-light complementary system, which can culture aquatic products in the net cage and catch fish in the net cage, thereby reducing the fishing area and improving the fishing efficiency. Moreover, the net cage is retractable, which further reduces the workload of fishing operation and improves the fishing efficiency.

The invention relates to a spraying device for production of a trimmer shell. Comprising a spraying box, and the top end of the spraying box is rotationally connected with a cover plate; the top end of the cover plate is fixedly connected with a sealing rubber strip; an observation window is formed in the side wall of the spraying box; a water outlet is fixedly connected to the side wall of the spraying box; the side wall of the spraying box is fixedly connected with a pair of storage boxes; a pair of nozzles is arranged on the inner side wall of the spraying box; the spray head is connected to the storage box through a pipeline; the bottom end of the spraying box is rotationally connected with a first fixing rod. The side wall of the first fixing rod is fixedly connected with a pair of electric push rods; the side wall of the first fixing rod is slidably connected with a supporting ring. The supporting ring is pushed through the electric push rod, so that the ejector rod forms uniform supporting force on the inner side of the shell, the shell can be quickly fixed, the preparation time is shortened, and the defects after spraying caused by the fact that a clamp shields an outer spraying surface during spraying of a spray head due to clamping and fixing from the outer side during shell fixing are reduced.
