[0029] Working principle: When the sensor 5 detects that the water pollution coefficient inside the culture pond 1 exceeds the standard, the circulation pump 24 is started, and the water in the pond is pumped out through the drainage pipe 21, filtered through the filter screen 222, and then re-injected into the culture pond 1 through the water injection pipe 25 connected to the water outlet of the circulation pump 24. At the same time, the water flow formed inside the culture pond 1 drives the blade 432 to rotate, thereby driving the rotating shaft 42 to rotate. The scraper 433 fixed on the outside of the fixed sleeve 431 is close to the bottom of the culture pond 1. When it rotates, it scrapes off the sediment at the bottom of the culture pond 1, and the sediment is also moved along with it. The water is discharged, which realizes automatic cleaning and reduces the pollution of sediment to the water quality. When the sensor 5 detects that the oxygen content of the water inside the breeding pond 1 is not up to standard, the motor 331 starts, and drives the second bevel gear 333 to drive the connecting rod 334 to rotate through the first bevel gear 332 fixed at its output end, so that the bevel gears fixed at both ends of the connecting rod 334 transmit the kinetic energy to the winding wheel 341. When the winding wheel 341 rotates, the oxygen supply pipe 342 wound on the inner side thereof is retracted and released, and the diving depth of the air stone 343 is adjusted to balance the oxygen content in the water area of ​​the pool, thereby reducing the risk of breeding.
