Anti-overflow structure for aquaculture

The utility model discloses an anti-overflow structure for aquaculture, which comprises a pool body, a drain pipe fixedly mounted in the pool body, a partition plate fixedly mounted in the drain pipe, a fixed shell fixedly mounted on the upper side of the drain pipe, a floating plate arranged in the pool body, a first connecting rod fixedly connected to the lower side of the floating plate, and a second connecting rod fixedly connected to the lower side of the first connecting rod. A second connecting rod is slidably connected into the fixing shell. When the water level in the pool body continuously rises, the floating plate is driven to move upwards, the floating plate drives the limiting block to move upwards through the first connecting rod, when the limiting block moves to the top end of the fixing cylinder, the limiting block drives the fixing cylinder and the second connecting rod to move upwards, the fixing cylinder slides along the limiting frame, and the second connecting rod drives the baffle to mov
