Description

Technical Field

[0001] This invention relates to the field of fish farming technology, specifically to a fish farming spawning device and operating method with controllable temperature, flow rate, and substrate conditions. Background Technology

[0002] While hydraulic structures provide significant benefits such as flood control, power generation, navigation, and water supply, they also significantly alter the natural hydrological conditions and morphological structure of rivers, negatively impacting aquatic ecosystems, especially fish reproductive behavior. Fish spawning devices can effectively address this issue. However, current fish spawning devices cannot simultaneously control multiple environmental factors and are mostly used indoors, failing to fully simulate the conditions for fish reproduction in the wild. The water temperature in most traditional tanks cannot be stably controlled within a suitable range, and the water is nearly stagnant, failing to simulate the stimulation of natural water flow, thus affecting fish reproduction. Furthermore, the unstable water quality in traditional tanks easily accumulates feces, uneaten feed, and harmful microorganisms, threatening fish health. Summary of the Invention

[0009] Preferably, the temperature control system includes an insulation layer installed on the inner wall of the breeding tank. The temperature control system has a compressor, condenser, dryer filter, capillary tube and evaporator connected in sequence to realize the circulation of refrigerant to achieve the temperature control effect. The condenser, dryer filter, capillary tube and evaporator are installed on the outer wall of the insulation layer.

[0010] Preferably, the water flow rate control system includes a turbine and a pipe to realize water circulation in the breeding tank and control the water flow rate. The first rectifier and the second rectifier are used to control the water flow rate to be uniform. The turbine is mounted on a turbine mounting plate.

[0013] Preferably, another aspect of the present invention provides a method for operating a fish spawning device with controllable temperature, flow rate, and substrate conditions, comprising the following steps: S1. The temperature regulation process relies on the temperature control system outside the breeding tank. The refrigerant is compressed into a high-temperature and high-pressure gas in the compressor and then enters the condenser, where it gradually dissipates heat and becomes a medium-temperature and high-pressure liquid. It then enters the dryer filter for filtration. After filtration, it enters the capillary tube and becomes a low-temperature and low-pressure mist-like liquid after flowing out of the capillary tube.

This device allows for precise control of water temperature and flow rate, utilizing natural river water as the culture water body, and allows for diverse substrate conditions to be configured according to the different breeding habits of various fish species. In the specific spawning process, the culture vessel 1 is first moved to the desired spawning location, and the fish to be spawned are then raised inside the culture tank 2. The temperature is adjusted by the temperature control system 22 according to the characteristics of the fish being cultured to achieve the optimal culture temperature. The water flow rate is adjusted by the water flow rate control system 23 to achieve the optimal flow rate effect, ensuring the best culture results. When the water quality inside the culture tank 2 needs to be changed, the substrate 28 is replaced.

[0028] Furthermore, the top of the aquaculture vessel 1 is equipped with multiple sets of wind turbines 11 for power generation, and one end of the top of the aquaculture vessel 1 is equipped with multiple sets of solar panels 15 for photovoltaic power generation.

[0029] Furthermore, the top of the aquaculture vessel 1 is equipped with ice blocks 16 for cooling. These ice blocks 16 facilitate subsequent temperature adjustments within the aquaculture tank 2 as needed, thereby achieving the optimal aquaculture temperature and ensuring aquaculture quality and effectiveness.

[0032] Furthermore, the aquaculture vessel 1 is provided with symmetrically arranged guide rails 17 located directly above the aquaculture tank 2. A safety bridge 27 is slidably installed on the guide rails 17, and a crane 14 for hoisting operations is fixedly installed on the top of the safety bridge 27. The safety bridge 27 facilitates subsequent adjustment of the position of the crane 14, thereby enabling it to cover the entire area of ​​the aquaculture tank 2.

[0033] Furthermore, a feed throwing device 12 for feeding is provided on the top of the aquaculture vessel 1 and on both sides of the aquaculture tank 2. The feed throwing device 12 facilitates the subsequent feeding during the aquaculture process.

[0034] Furthermore, pulleys 271 are provided at the four corners of the safety bridge 27, and the pulleys 271 are slidably installed inside the guide rail 17. The pulleys 271 facilitate the smooth movement of the safety bridge 27.

Through the aforementioned temperature control system 22, the water temperature inside the breeding tank 2 can be effectively controlled, thereby achieving the optimal breeding environment.

[0037] Furthermore, the water flow rate control system 23 includes a turbine 232 and a pipe 233 to achieve water circulation and control the water flow rate within the breeding tank 2. A first rectifier 24 and a second rectifier 29 are used to control the water flow rate uniformly. The turbine 232 is mounted on a turbine mounting plate 231. The inlet of the pipe 233 is located after the second rectifier 29, and the outlet of the turbine 232 is located before the first rectifier 24. The water flow rate control system 23 can precisely control the water flow rate to meet the breeding needs of different fish species.

The dissolved oxygen cone 132 is connected to the aquaculture tank 2 via a water pump 134, and is also connected to the aquaculture tank 2 via a water outlet 133. During the specific operation of the oxygen cone 13, when oxygen needs to be supplied to the aquaculture tank 2, the water pump 134 draws water from the aquaculture tank 2 into the dissolved oxygen cone 132, while the oxygen generator 131 simultaneously delivers oxygen to the dissolved oxygen cone 132. The two mix in the dissolved oxygen cone 132 and are discharged into the aquaculture tank 2 through the water outlet 133.

[0040] Furthermore, the three sets of turbines 232 are separated by baffles, and different flow velocity regions are formed by adjusting their rotational speed. By employing different flow velocity regions, it is possible to adapt well to different fish species, thereby effectively enhancing their adaptability.

[0041] Example 2: Furthermore, another aspect of the present invention provides a method for operating a fish spawning device with controllable temperature, flow rate, and substrate conditions, comprising the following steps: S1. The temperature regulation process relies on the temperature control system 22 outside the breeding tank 2. The refrigerant is compressed into a high-temperature and high-pressure gas in the compressor 226 and then enters the condenser 225, where it gradually dissipates heat and becomes a medium-temperature and high-pressure liquid. It then enters the dryer filter 224 for filtration. After filtration, it enters the capillary tube 223 and becomes a low-temperature and low-pressure mist-like liquid after flowing out of the capillary tube 223. Finally, it enters the evaporator 222, where it absorbs a large amount of heat and evaporates, achieving cooling. Then, it enters the compressor 226 again to cycle through this process. The inner wall of the breeding tank 2 is insulated with a heat-insulating layer 221 to maintain a constant temperature. S2. The water flow speed is adjusted by the water flow speed control system 23. The water in the breeding tank 2 is controlled by adjusting the rotation speed of the turbine 232.

S3. The bottom sediment 28 in the breeding box can be replaced by the hanging tower 14. When the water quality detection sensor 26 detects that the pollutants in the bottom sediment have decreased, the hanging tower 14 is controlled to slide on the guide rail 17 via the pulley 271, and then the bottom sediment 28 is replaced via the hook 142. At the same time, the breeding box 2 exchanges with the river water through the drain outlet 21. S4. Oxygen in the water is provided by oxygen cone 13. Water pump 134 draws water from the breeding tank 2 into dissolved oxygen cone 132, while oxygen generator 131 delivers oxygen to dissolved oxygen cone 132.
