Description

Technical Field

[0001] The present application belongs to the field of aquaculture technology, and specifically relates to a drainage and ventilation device for tilapia farming. Background Art

[0002] Tilapia is an important freshwater fish. Due to its large size, delicious meat and strong adaptability, it is widely farmed. Tilapia farming usually includes pond farming and cage farming. In these farming processes, oxygenation and water monitoring are crucial. Oxygenation can ensure smooth water flow and sufficient oxygen, which facilitates the breathing of tilapia and promotes its healthy growth. At the same time, water monitoring, especially the concentration monitoring of ammonia nitrogen and harmful substances, can help to promptly detect and deal with water quality problems, and avoid the impact of water quality fluctuations on fish health. Effective oxygenation and water quality monitoring can not only improve farming efficiency, but also reduce fish losses and ensure that tilapia grow in the best environment.

[0003] During tilapia farming, regular or real-time water monitoring is crucial for successful farming. Tracking key indicators such as dissolved oxygen, pH, and ammonia nitrogen concentrations helps to promptly identify and address potential problems, ensuring the healthy growth of tilapia.

[0004] However, the existing monitoring method mainly involves inserting sensors or detectors into the water body for detection. This method has certain problems. Since some harmful substances in the water body may sink to the bottom, relying solely on sensors inserted into the water body cannot accurately monitor the concentration of harmful substances in the water body near the bottom, thereby affecting the accuracy of monitoring. To this end, a drainage and ventilation device for tilapia farming is provided. Utility Model Content

A battery is fixedly mounted on the top surface of the connecting plate, and the photovoltaic panel is electrically connected to the battery.

[0008] In a preferred embodiment, a water pump is fixedly installed on the top surface of the protective shell, a liquid inlet pipe is fixedly installed on the liquid inlet end of the water pump, one end of the liquid inlet pipe passes through the top surface of the mounting support rod, and a liquid discharge pipe is fixedly installed on the liquid outlet end of the water pump.

[0009] In a preferred embodiment, two ventilation pipes are fixedly mounted on the outer surface of the protective shell.

[0010] In a preferred embodiment, a reinforcing rod is fixedly mounted on the outer surface of the support rod, and one end of the reinforcing rod away from the support rod is fixed to the outer surface of the fixing plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. In the present application, due to the adoption of the above-mentioned scheme, the driving motor drives the mounting plate, the cylindrical shell and the stirring blades to rotate in the water body, providing sufficient dissolved oxygen for the organisms in the water. At the same time, when the stirring blades rotate, the bottom water body will flow upward and the top water body will flow to both sides. At this time, through the set multiple monitoring sensors, the upward-flowing bottom water body can be effectively monitored. When the sensor detects that the harmful substances in the water exceed the set value and issues an alarm, the operator can start the water pump to discharge the water inside the breeding pond or breeding cage through the drainage pipe. In this way, not only can the water body be replaced in time, but also the accumulation of harmful substances in the breeding environment can be effectively controlled. The device can effectively increase oxygen through the rotation of the cylindrical shell and the stirring blades. At the same time, during the oxygenation process, the bottom water body is pushed upward to maintain the uniformity of the water body, which can more accurately reflect the true condition of the water body and improve the accuracy of water body monitoring.

[0027] refer to Figure 1Two ventilation pipes 21 are fixedly installed on the outer surface of the protective shell 7; the ventilation pipes 21 are provided to facilitate the circulation of air inside the protective shell 7 and the outside air, thereby facilitating heat dissipation inside the protective shell 7.

[0028] The implementation principle of the embodiment of the drainage and ventilation device for tilapia farming in the present application is as follows: the operator first places the device in a farming pond or a farming cage, and uses multiple floats 3 to make it float on the water surface. At this time, multiple monitoring sensors 11 are located in the water body, which can monitor the dissolved oxygen, pH value and ammonia nitrogen concentration in real time. At this time, the operator starts the drive motor 8, and the drive motor 8 drives the mounting plate 5, the cylindrical shell 4 and the stirring blade 6 to rotate in the water body. This rotation action will generate water flow, absorb oxygen in the water body and form bubbles on the water surface. This not only increases the contact area between water and air, but also effectively promotes the dissolution of oxygen, providing sufficient dissolved oxygen for the organisms in the water. At the same time, when the stirring blade 6 rotates, it will make the bottom The water body flows upstream, and the top water body flows to both sides. At this time, through the set multiple monitoring sensors 11, the bottom water body flowing upward can be effectively monitored, and the monitoring data is fed back to the terminal through the controller 14. When the sensor detects that the harmful substances in the water exceed the set value, the operator can start the water pump 18 and discharge the water inside the breeding pond or breeding cage through the drainage pipe 20. In this way, not only can the water body be replaced in time, but also the accumulation of harmful substances in the breeding environment can be effectively controlled. The device has a simple structure and is easy to operate. It can effectively increase oxygen through the rotation of the cylindrical shell 4 and the stirring blade 6. At the same time, during the oxygenation process, the bottom water body is pushed upstream, which can more accurately reflect the real condition of the water body and improve the accuracy of water body monitoring.
