[0003] The recirculating aquaculture shrimp system has problems such as a small dirt collection basket, easy blockage, and once overflow occurs after blockage, shrimp will escape, increasing the workload in the production management process. It is difficult to effectively prevent live shrimp from escaping while ensuring the smooth discharge of dirt such as shrimp shells, dead shrimp, and residual bait feces from the aquaculture system, and to make the live shrimp in the anti-escape basket automatically return to the pond.

Detailed Embodiments

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0024] As Figures 1 to 3 shown, in an embodiment of the present invention, it includes:

[0025] A shrimp shell collection device for preventing live shrimp from escaping and automatically returning to the pond in a circulating water shrimp farming pond, including a farming pond, characterized in that the shrimp shell collection device for preventing live shrimp from escaping and automatically returning to the pond in the circulating water shrimp farming pond further includes:

[0026] A central water returner 1 and a water distribution tank 2;

[0027] A return water pipe 3 is connected to the top of the central water returner 1, a buckle plate 4 is arranged on the top of the central water returner 1, and a downward vertical rubber sheet 5 is arranged on the side of the central water returner 1;

[0028] The water distribution tank 2 includes:

[0029] A water distribution tank frame main body 6, an inlet water pipe 7 and a live shrimp return pipe 8 are connected to the water distribution tank frame main body 6, and the inlet water pipe 7 is connected to the return water pipe 3;

[0030] A shrimp shell collection tank 9 is arranged on one side of the water distribution tank frame main body 6, a shrimp shell sewage discharge pipe 10 is connected to the shrimp shell collection tank 9 of the water distribution tank, and an electric valve 11 is arranged on the shrimp shell sewage discharge pipe 10;

[0031] A drainage partition 12 is installed inside the water distribution tank frame main body 6, a main drainage pipe stopper 13 is arranged on one side of the drainage partition 12, a backwash water pump 14 is connected to the main drainage pipe stopper 13, and an output end of the backwash water pump 14 is connected to a backwash pipe 15;

[0032] In an embodiment of the present invention, the lower edges of the rubber sheets 5 are flush, and the gap between the rubber sheets 5 and the bottom of the farming pond is 3-8 mm, and the gap between adjacent rubber sheets 5 is 0-10 mm.

[0033] In an embodiment of the present invention, the specific gravity of the baffle of the inlet water pipe 7 to the baffle of the live shrimp return pipe 8 is 1.1-1.5 g / cm 3 , and the baffles of the inlet water pipe 7 and the live shrimp return pipe 8 can be opened under the impact of water flow and can fall back by gravity when the water flow is slow.

[0034] As Figure 2As shown in the figure, in the embodiment of the present invention, the main drain pipe closer 13 includes:

[0035] A cylindrical shell 16, an electric telescopic rod 17 fixed on the outer top surface of the cylindrical shell 16, and a plugging disc 18 connected to the lower end of the electric telescopic rod 17.

[0036] The culture water containing shrimp shells and shrimp feces enters the inside of the central water return device 1 through the bottom gap of the central water return device 1 at the bottom of the culture pond, and successively passes through the water return pipe 3 and the water inlet pipe 7 to enter the water distribution tank 2. Subsequently, when the state of discharging live shrimp is not turned on, the shrimp shells gather at the bottom of the shrimp shell collection tank 9, and the shrimp feces and water pass through the porous drainage partition plate 12 and enter one side of the main drain pipe closer 13, and then enter the main water return pipe through the bottom gap of the main drain pipe closer 13; when the shrimp shell discharging program is running, the electric push rod of the main drain pipe closer 13 extends to close the main drain pipe. After the water level in the water distribution tank 2 reaches the same level as the water level in the culture pond, the baffle of the water inlet pipe 7 falls under the action of gravity, and the backflush water pump is turned on. At this time, the shrimp shells intercepted on the drainage partition plate 12 are washed into the shrimp shell collection tank 9. At the same time, the water level inside the water distribution tank 2 gradually becomes higher than the water level in the culture pond, and the baffle of the live shrimp return pipe 8 is opened under the impact of the water flow, and the live shrimp leave the water distribution tank to achieve automatic return to the pond. After most of the live shrimp have returned to the pond, the backflush water pump 14 is turned off, and the electric push rod of the main drain pipe closer 13 retracts, and the water distribution tank 2 returns to the normal drainage state. In the normal drainage state, the electric valve of the shrimp shell sewage discharge pipe 10 can be periodically opened to collect the shrimp shells and dead shrimp into a special collection device outside the culture pond through the shrimp shell sewage discharge pipe 10.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
