The shrimp pond pollution discharge method based on the photoelectric-driven shrimp and water return gap automatic control coupling as claimed in claim 1, characterized in that: the controller controls the live shrimp driving device to emit electric pulses and/or stroboscopic light to drive the live shrimps in the vicinity of the water discharge gap.
3. The utility model provides a shrimp pond waste fitting discharging based on photoelectricity drives shrimp and return water gap automatic control coupling which characterized in that: comprises a water return disc, a water return pipe, a water return disc lifting device, a live shrimp driving device and a controller;
the water return disc is arranged at the bottom of the pond and forms a sewage discharge gap for discharging sewage at the bottom of the pond and preventing live shrimps from escaping;
the water return pipe is connected with the water return disc and is used for discharging the sewage at the bottom of the pool entering the water return disc out of the culture pond;
the water return disc lifting device is connected with the water return disc and is used for adjusting the size of the sewage discharge gap;
the live shrimp driving device is arranged on the water return disc and used for driving live shrimps detained near the drainage gap;
the controller controls the water return disc lifting device to adjust the size of the water discharge gap and controls the live shrimp driving device to drive live shrimps detained near the water discharge gap.
4. The shrimp pond pollution discharge device based on the photoelectric-driven shrimp and water return gap automatic control coupling of the claim 3, characterized in that: the live shrimp driving device is a pulse discharging device and/or an LED stroboscopic light source.
5. The shrimp pond pollution discharge device based on the photoelectric-driven shrimp and water return gap automatic control coupling of claim 4, wherein: the pulse discharge device comprises a pulse electrode arranged on the outer edge of the water return disc and a pulse power supply used for discharging the pulse electrode.
6. The shrimp pond pollution discharge device based on the photoelectric-driven shrimp and water return gap automatic control coupling of any one of claims 3 to 5, wherein: the water return plate lifting device comprises a guide rod fixedly connected with the bottom of the pool, a fixed base plate arranged at the upper end of the guide rod, a driving motor fixed on the fixed base plate, a transmission screw rod connected with the driving motor, a movable base plate arranged on the guide rod and capable of moving up and down along the guide rod, a nut fixed on the movable base plate and connected with the transmission screw rod, and a guide rod sleeve arranged on the guide rod and used for connecting the movable base plate with the water return plate.
