DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides an embodiment: a self-draining aquaculture pond, comprising a cleaning device 1 and an automatic sewage discharge device 2, the automatic sewage discharge device 2 is arranged on the cleaning device 1, the cleaning device 1 comprises a sewage discharge cone pipe 3, a guide plate 4, a turbine 5, a filter screen 6, a rotating shaft 7, a cleaning rod 8 and a sliding block 9, the guide plate 4 is evenly arranged, and the guide plate 4 is fixedly connected to the inner end of the sewage discharge cone pipe 3, the filter screen 6 is fixedly connected to the top of the sewage discharge cone pipe 3, the rotating shaft 7 is rotatably connected to the middle part of the filter screen 6 through the rotating shaft, three cleaning rods 8 are evenly arranged, and one end of the cleaning rod 8 is fixedly connected to the rotating shaft 7, the sliding block 9 is fixedly connected to the end of the cleaning rod 8 away from the rotating shaft 7, and the middle part of the top of the turbine 5 is fixedly connected to the bottom end of the rotating shaft 7.

[0019] The automatic sewage discharge device 2 includes a delivery pipe 10, a PLC controller 11, a protective cover 12, a safety water pipe 13, a solenoid valve 14, a flow sensor 15 and a sewage pipe 16. The PLC controller 11 is fixedly installed on the delivery pipe 10, the protective cover 12 is slidably inserted in the top of the delivery pipe 10, one end of the safety water pipe 13 is fixedly connected to the end of the delivery pipe 10 close to the protective cover 12, the sewage pipe 16 is fixedly connected to the delivery pipe 10, and the PLC controller 11 is located between the protective cover 12 and the sewage pipe 16, the flow sensor 15 is fixedly connected to the sewage pipe 16, and the sensing end of the flow sensor 15 is located inside the sewage pipe 16, and the solenoid valve 14 is fixedly installed on the sewage pipe 16.

[0020] One end of the delivery pipe 10 away from the protective cover 12 is fixedly connected to the bottom end of the sewage cone pipe 3, and the water in the breeding pond is delivered to the delivery pipe 10 through the bottom end of the sewage cone pipe 3 for discharge.

[0021] The cleaning rod 8 is located above the filter screen 6 , and the sliding block 9 is slidably connected to the outer end of the filter screen 6 . When the cleaning rod 8 rotates, both ends of the cleaning rod 8 are supported by the rotating shaft 7 and the sliding block 9 .

[0022] The PLC controller 11 is electrically connected to the solenoid valve 14 and the flow sensor 15 respectively by wires. The PLC controller 11 is programmed to control the opening and closing of the solenoid valve 14 through the flow value counted by the flow sensor 15 .

[0023] The drainage cone 3 is arranged at the middle of the bottom of the culture pond, and the end of the safety water pipe 13 close to the protective cover 12 is level with the safe water level of the culture pond. The culture pond discharges sewage through the drainage cone 3 and discharges excess water through the safety water pipe 13 to prevent water from flooding the culture pond.

[0024] Working principle: During use, the PLC controller 11 is first used to set the scheduled sewage discharge time and sewage discharge volume. When the sewage discharge time is reached, the PLC controller 11 controls the solenoid valve 14 to open the valve, and the water in the breeding pond and the waste materials at the bottom of the breeding pond flow into the delivery pipe 10 through the sewage discharge cone pipe 3 and are discharged through the sewage discharge pipe 16. When the sewage passes through the sensing end of the flow sensor 15, the sensing end of the flow sensor 15 counts the flow of the sewage. When the water in the breeding pond enters the sewage discharge cone pipe 3, the filter screen 6 isolates large pieces of debris outside to prevent it from flowing into the delivery pipe 10 and getting blocked. In the process of sewage flowing into the sewage discharge cone pipe 3, it impacts the turbine blades of the turbine 5. The turbine blades of the turbine 5 rotate due to the impact, thereby driving the turbine 5 to rotate. The rotation of the wheel 5 drives the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 drives the cleaning rod 8 to rotate. The rotation of the cleaning rod 8 scrapes off the large debris at the top of the filter screen 6, thereby keeping the top of the sewage cone pipe 3 unobstructed, and the sewage entering the sewage cone pipe 3 rotates under the guidance of the guide plate 4, thereby accelerating the flow speed of the sewage. When the sewage flow rate counted by the flow sensor 15 reaches a predetermined value, the PLC controller 11 controls the solenoid valve 14 to close the valve, and automatic sewage discharge can be completed at this time. When the water level in the breeding pond is too high and exceeds the safe water level, the water in the breeding pond is transported to the safety water pipe 13 through the delivery pipe 10, and is discharged through the safety water pipe 13 until the water level in the breeding pond is lower than the safe water level, thereby keeping the water level in the breeding pond at a safe water level.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
