DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the specific implementation modes of the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0026] Figure 1 and Figure 2It is a specific embodiment of the new bottom sewage discharge and bottom oxygenation integrated system of the present invention. The system includes a sewage discharge and oxygenation port 1 installed at the bottom of the fish pond 10 and connected to the fish pond 10, a three-way pipe 2, a water pump 6, an air pump 7, a water body information collection module, a meteorological information collection module data processing module and a control module. The three branches of the three-way pipe 2 are respectively connected to the sewage discharge and oxygenation port 1, the input end of the water pump 6, and the output end of the air pump 7. The output end of the water pump 6 is connected to the outside world for sewage discharge from the fish pond 10. The input end of the air pump 7 is connected to the outside world for oxygenation of the fish pond 10. When the water pump 6 transports wastewater containing waste for sewage discharge and the air pump 7 transports air for oxygenation, a part of the pipeline can be shared, so as to realize the integration of bottom sewage discharge and bottom oxygenation of the fish pond 10. The water pump 6 and the air pump 7 are both installed in the pump room 9 through the mounting base 8, and the pump room 9 is arranged on one side of the fish pond 10. The bottom of the fish pond 10 is provided with a plurality of sewage discharge and oxygenation ports 1, all of which are connected to the three-way pipe 2. The arrangement of the plurality of sewage discharge and oxygenation ports 1 is as follows: a sewage discharge and oxygenation port 1 is provided in the center, and the remaining sewage discharge and oxygenation ports 1 are arranged in a circumferential direction around the sewage discharge and oxygenation port 1 at the center. The provision of a plurality of sewage discharge and oxygenation ports 1 can increase the speed of sewage discharge and oxygenation. A water circuit electromagnetic switch 3 and a gas circuit electromagnetic switch 4 are respectively provided on the two branches connected to the water pump 6 and the air pump 7 on the three-way pipe 2. The water circuit electromagnetic switch 3 and the gas circuit electromagnetic switch 4 are respectively used to control the on and off of the branches where they are located, so as to realize that the two working processes of sewage discharge and oxygenation are independent of each other. The water pump 6 and the air pump 7 are both connected to the bottom of the fish pond 10, so that the water pump 6 and the air pump 7 can discharge sewage and increase oxygen at the bottom of the fish pond 10 respectively. The sewage discharge and oxygenation outlet 1 comprises a discharge outlet 13, a filter layer 12 and a guide layer 11 which are sequentially arranged from a three-way pipe 2 to the outside. The guide layer 11 is provided with a plurality of guide holes 111 arranged at intervals in the circumferential direction. The filter layer 12 is provided with a plurality of filter holes 121 arranged at intervals for filtering objects with a larger volume, such as stones, etc., and also for preventing fish from flowing into the three-way pipe 2. The guide hole 111 is in a crescent shape, and the crescent-shaped guide hole 111 is more likely to generate vortices when discharging sewage, thereby increasing the sewage discharge speed. The discharge outlet (13) is in an inverted truncated cone shape, and the large end of the discharge outlet (13) is arranged close to the filter layer (12), and the small end is arranged close to the three-way pipe (2), so that the sewage is drained into the three-way pipe 2 when discharging sewage. A first diversion hole 112 is arranged between the adjacent diversion holes 111, and the size of the first diversion hole 112 is smaller than that of the diversion hole 111, and the first diversion hole 112 and the diversion hole 111 do not contact each other. A plurality of second flow diversion holes 113 arranged at intervals in the circumferential direction are arranged at the center of the flow diversion layer 11 . The size of the second flow diversion holes 113 is smaller than that of the flow diversion holes 111 , and the second flow diversion holes 113 and the flow diversion holes 111 do not contact each other.A large amount of air is likely to remain in the three-way pipe 2 after oxygenation. When discharging sewage, the remaining air in the three-way pipe 2 will be impacted by the water flow. Since the air density is less than the sewage density, the remaining air in the three-way pipe 2 will rise. When the sewage generates a vortex during the sewage discharge process, the remaining air is not easy to flow upward from the guide hole 111 due to the influence of the centrifugal force of the vortex. The first diversion hole 112 and the second diversion hole 113 are provided to facilitate the circulation of the remaining air.

[0027] The water body information collection module is used to collect water body information; the water body information collection module includes a dissolved oxygen sensor, an ammonia nitrogen sensor and a nitrite nitrogen sensor, which are used to collect dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content respectively. Dissolved oxygen is a necessary condition for fish to survive. Adequate dissolved oxygen content in water is conducive to fish growth. Real-time monitoring of dissolved oxygen content in water helps to control dissolved oxygen content. Ammonia nitrogen and nitrite nitrogen are the main pollutant indicators of fish pond water. Excessive ammonia nitrogen and nitrite nitrogen content in water will threaten fish health and thus affect fish farming. Real-time monitoring of ammonia nitrogen and nitrite nitrogen content in water helps to control ammonia nitrogen and nitrite nitrogen content.

[0028] The meteorological information collection module is used to collect meteorological information; wherein the meteorological information collection module includes a temperature sensor, a humidity sensor, a wind speed sensor, and an air pressure sensor, which are respectively used to collect temperature, humidity, wind speed, and air pressure. The dissolved oxygen content in the fish pond is negatively correlated with the temperature and humidity, and positively correlated with the air pressure and wind speed, that is, the dissolved oxygen content will decrease with the increase of temperature and humidity, and increase with the increase of air pressure and wind speed. The ammonia nitrogen content and the nitrite nitrogen content are positively correlated with the temperature and humidity, and negatively correlated with the air pressure, that is, the ammonia nitrogen content and the nitrite nitrogen content will increase with the increase of temperature and humidity, and decrease with the increase of air pressure. Therefore, the trend of dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content in water can be predicted based on the data of temperature, humidity, wind speed, and air pressure collected by the meteorological information collection module, and the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content data collected in real time by the dissolved oxygen sensor, ammonia nitrogen sensor, and nitrite nitrogen sensor can be combined to predict the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content at a future moment.

[0029] The data processing module is connected to the water body information collection module and the meteorological information collection module by signal. The data processing module establishes the sewage discharge and oxygenation model for different breeding objects at different breeding stages based on the artificial experience of fish breeding, and outputs the oxygenation and sewage discharge timetable according to the fish information, water body information and meteorological information. The fish information includes the type of fry put into the fish pond 10, the number of fry, the weight of fry, the breeding time and the recorded last feeding time and feeding amount. Different types of fish are involved in the breeding process, and each fish has its own growth stage. According to the sewage discharge and oxygenation model, the oxygenation and sewage discharge of the breeding process are controlled, and according to the recorded feeding time and feeding amount, combined with the growth law of the fish of this type, it can be inferred what breeding stage the fish of this type is in after a period of time, and the sewage discharge and oxygenation model of the fish of this type in the breeding stage is matched, so that the entire growth process of the fish of this type can be controlled.

[0030] The data processing module outputs the oxygenation and sewage discharge schedule not only based on the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content data collected in real time by the dissolved oxygen sensor, ammonia nitrogen sensor and nitrite nitrogen sensor, but also combines the temperature, humidity, wind speed and air pressure to predict the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content trends in the water, so as to improve the accuracy of the output oxygenation and sewage discharge schedule. At the same time, by comparing the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content data collected in real time by the dissolved oxygen sensor, ammonia nitrogen sensor and nitrite nitrogen sensor with the predicted data, it can be verified whether the predicted data is accurate. When the predicted data is found to be biased, the data processing module dynamically corrects the relationship between the temperature, humidity, wind speed and air pressure data and the dissolved oxygen content, ammonia nitrogen content and nitrite nitrogen content data, so as to achieve precise control.

[0031] The control module is connected to the water pump 6, the air pump 7, the water circuit electromagnetic switch 3, and the air circuit electromagnetic switch 4 by signals, and the control module is connected to the data processing module by signals. The control module controls the opening and closing of the water pump 6, the air pump 7, the water circuit electromagnetic switch 3, and the air circuit electromagnetic switch 4 according to the oxygenation and sewage discharge schedule. When the control module reads that the oxygenation and sewage discharge schedule is displayed as the oxygenation time, the control module sends a control signal to control the air pump 7 and the air circuit electromagnetic switch 4 to open, and controls the water pump 6 and the water circuit electromagnetic switch 3 to close, and then the air pump 7 transports the outside air to the bottom of the fish pond 10 through the three-way pipe 2 to oxygenate the water body of the fish pond 10. When the control module reads that the oxygenation and sewage discharge schedule is displayed as the sewage discharge time, the control module sends a control signal to control the water pump 6 and the water circuit electromagnetic switch 3 to open, the air pump 7 and the air circuit electromagnetic switch 4 to close, and the water pump 6 starts to discharge the waste at the bottom of the fish pond 10 from the sewage discharge and oxygenation port 1. The waste includes feces, leftover bait, biological debris, and organic solid particles. When it is determined during the oxygenation process that sewage discharge is required, the oxygenation work is stopped first, and then the sewage discharge work is carried out. After the sewage discharge is completed, the oxygenation work is continued; specifically, the control module sends a control signal to control the air pump 7 and the air circuit electromagnetic switch 4 to turn off, stop the oxygenation work, control the water pump 6 and the water circuit electromagnetic switch 3 to turn on, and carry out sewage discharge. After the sewage discharge is completed, the water pump 6 and the water circuit electromagnetic switch 3 are controlled to turn off, and then the air pump 7 and the air circuit electromagnetic switch 4 are controlled to turn on to carry out the oxygenation work.

[0032] For example, a batch of 300 largemouth bass fry weighing 11.87±1.42g are put into the fish pond 10. After testing, the temperature is 20℃, the humidity is 45%, the wind speed is 3.3m / s, the air pressure is 1008hPa, the initial dissolved oxygen content is 6mg / L, the ammonia nitrogen content is 0.5mg / L, and the nitrite nitrogen content is 0.3mg / L. Feeding is performed at two time points, 4:00 and 19:00. The data processing module obtains from the sewage discharge and oxygenation model that the fish of this type mainly excretes within 3-6h after each feeding at the fry stage. The data processing module outputs the sewage discharge time as 6h after each feeding, that is, at 10:00 and 1:00, the control module sends a control signal to control the water pump 6 and the water circuit electromagnetic switch 3 to open, and the air pump 7 and the air circuit electromagnetic switch 4 to close, so as to discharge sewage from the fish pond 10. The data processing module outputs continuous oxygenation between 12:30 and 13:30. At this time, the control module sends a control signal to control the air pump 7 and the air circuit electromagnetic switch 4 to turn on, and to control the water pump 6 and the water circuit electromagnetic switch 3 to turn off. Then the air pump 7 transports the outside air to the bottom of the fish pond 10 through the three-way pipe 2 to oxygenate the water in the fish pond 10. After oxygenation, the air pump 7 and the air circuit electromagnetic switch 4 are controlled to be closed.

[0033] Cameras are installed around the fish pond 10 for collecting water body images. The camera is connected to the data processing module signal to transmit the collected water body images to the data processing module, and the data processing module identifies the waste content in the water body image. On the one hand, it avoids the fish pond 10 from being uncleanly discharged after sewage is discharged. If it is judged that the sewage is not discharged cleanly, and the ammonia nitrogen content and the nitrite nitrogen content exceed the threshold value of normal fish growth, the control module sends a control signal to control the water pump 6 and the water circuit electromagnetic switch 3 to turn on, and the air pump 7 and the air circuit electromagnetic switch 4 to turn off, and the fish pond 10 is discharged again. On the other hand, by comparing the excretion time of this type of fish recorded in the sewage discharge and oxygenation model at this breeding stage with the change of waste content in the water body image identified by the data processing module, it can be verified whether the excretion time of this type of fish recorded in the sewage discharge and oxygenation model at this breeding stage is correct. When there is a deviation between the excretion time of this type of fish recorded in the sewage discharge and oxygenation model during the breeding stage and the actual excretion time, the data processing module dynamically corrects the excretion time of this type of fish recorded in the sewage discharge and oxygenation model during the breeding stage to improve the control accuracy of the fish breeding process.

Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
