The invention belongs to the field of fish culture, and particularly relates to a
juvenile fish outdoor culture protection device. The
juvenile fish outdoor culture protection device comprises a culture pond, a clamping sleeve is fixedly connected to the inside of the culture pond, a square column is inserted into the clamping sleeve, a supporting plate is fixedly connected to the upper end of the square column, and a
threaded rod is fixedly connected to the upper end of the supporting plate. The upper end of the
threaded rod is fixedly connected with a long strip plate, two symmetrically-distributed rain baffles are hinged to the long strip plate, rubber covers are bonded to the rain baffles, and the lower ends of the rain baffles make contact with the upper end of the culture pond. According to the scheme, by designing a water pump, a water inlet
pipe, a first hose, a connecting sleeve, a
barrel, a through groove, a filter screen, a bent
pipe, a long
pipe, a spray head, a first valve, a second hose, a water outlet pipe, a
branch pipe, a second valve, a third hose, an
air pump, an air outlet pipe, an air inlet pipe, a filter head and other parts, a cleaning and blow-
drying device for a solar panel can be formed, and cleaning and blow-
drying work can be conveniently conducted on the solar panel; and the use is convenient.
