Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and more specifically, to an energy-saving integrated aeration and feeding device for aquaculture. Background Technology

[0002] In the aquaculture industry, the quality of the water environment is directly related to the growth rate and health of fish. As a common aquaculture environment, pond water quality management is particularly important. Among them, the dissolved oxygen content in the water is one of the key factors affecting fish growth. Low dissolved oxygen environment will not only affect the normal respiration of fish, but may also cause diseases and lead to a decline in aquaculture efficiency.

[0003] Currently, there are various oxygenation devices and feeders for dissolved oxygen in pond water available on the market. However, these devices often only perform their respective functions and cannot maximize the aquaculture effect. Utility Model Content

[0004] To at least partially solve the above problems, this utility model provides an energy-saving integrated aeration and feeding device for aquaculture, comprising: a submersible pump; an axial-flow turbine connected to the top of the submersible pump, the submersible pump being used to pump water into the axial-flow turbine to drive the main shaft of the axial-flow turbine to rotate; and a feeding mechanism comprising a feed cylinder and feeding pipes, the feed cylinder being connected to the top of the axial-flow turbine, and multiple feeding pipes being arranged radially along the feed cylinder and circumferentially around the feed cylinder, and the feeding pipes communicating with the feed cylinder, wherein when the main shaft of the axial-flow turbine rotates, the multiple feeding pipes are used to synchronously transport the feed in the feed cylinder.

[0005] Optionally, the feed cylinder includes a cylinder body and a stirring component, the stirring component being disposed inside the cylinder body, and the stirring component being drivenly connected to the main shaft of the axial flow turbine to rotate the stirring component.

[0006] Optionally, the stirring component includes a stirring shaft and a stirring rod. One end of the stirring shaft is connected to the main shaft of the axial flow turbine, and the other end of the stirring shaft is rotatably connected to the inner top surface of the cylinder. The stirring rod is connected to the stirring shaft.

[0007] Optionally, the feeding mechanism further includes a transmission component, and the stirring shaft is driven to the feeding pipe via the transmission component so that the feed is conveyed in the feeding pipe.

[0008] Optionally, the feeding pipe includes a pipe body and an auger shaft. The auger shaft is disposed in the pipe body. One end of the auger shaft is connected to the transmission component, and the other end of the auger shaft is rotatably connected to the inner end face of the pipe body away from the material cylinder. The lower circumferential surface of the pipe body is provided with a plurality of feeding holes along its extension direction.

[0009] Optionally, the transmission component includes a driving bevel gear and a driven bevel gear. The driving bevel gear is mounted on the stirring shaft, and multiple driven bevel gears are meshed with the driving bevel gear. The driven bevel gears are mounted on the ends of the corresponding auger spiral shaft.

[0010] Optionally, the energy-saving integrated aeration and feeding equipment for aquaculture also includes a water pumping pipe, which includes a bracing pipe and a connecting pipe. Multiple bracing pipes are arranged around the circumference of the submersible pump and are inclined relative to the submersible pump. Adjacent water pumping pipes are connected through the connecting pipe, and the top of the multiple bracing pipes is connected to the water inlet of the submersible pump.

[0011] Optionally, the energy-saving integrated aeration and feeding equipment for aquaculture further includes a water delivery pipe and a spiral pipe. One end of the water delivery pipe is connected to the outlet of the submersible pump, and the other end of the water delivery pipe is connected to the spiral pipe. The spiral pipe is provided with multiple spray holes along its extension direction, and the spray holes face the runner of the axial flow turbine.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing a submersible pump inside the pond, with the axial-flow turbine connected to the top of the pump, the turbine can be positioned above the water surface. The submersible pump draws water from the pond into the turbine, oxygenating the water before it is discharged back into the pond. This increases the dissolved oxygen content, providing a suitable environment for fish, shrimp, and other aquatic organisms. Simultaneously, the feed pipe delivers feed from the feed hopper, ensuring feed is placed in oxygen-rich water. This makes it easier for fish and shrimp to find food, improving feed utilization and achieving better aquaculture results and energy savings. Attached Figure Description

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides an energy-saving integrated aeration and feeding device for aquaculture, including: a submersible pump 2; an axial-flow turbine 3 connected to the top of the submersible pump 2, the submersible pump 2 being used to pump water into the axial-flow turbine 3 to drive the main shaft of the axial-flow turbine 3 to rotate; and a feeding mechanism 4, which includes a feed cylinder 41 and feeding pipes 42, the feed cylinder 41 being connected to the top of the axial-flow turbine 3, and multiple feeding pipes 42 being arranged radially along the feed cylinder 41 and circumferentially around the feed cylinder 41, and the feeding pipes 42 communicating with the feed cylinder 41, the multiple feeding pipes 42 being used to synchronously transport the feed in the feed cylinder 41 when the main shaft of the axial-flow turbine 3 rotates.

[0021] Specifically, the depth direction of pond 100 is along the negative Z-axis in the diagram. It's important to note that aquatic organisms such as fish and shrimp exhibit oxygen-seeking behavior, meaning they tend to be active in waters with higher dissolved oxygen levels. This is because sufficient dissolved oxygen is essential for their respiration and metabolism. Therefore, when feed is placed in areas with sufficient dissolved oxygen, these organisms will more actively forage in these areas, thus improving feed utilization. Traditional feeding methods often result in feed waste because some feed may be placed in areas with insufficient dissolved oxygen or low biological activity, making it difficult for fish and shrimp to find food. However, feeding simultaneously with aeration ensures that the feed is placed in areas with frequent biological activity and sufficient dissolved oxygen, thereby reducing feed waste. It should be noted that since feed cylinder 41 is located in the middle of pond 100, staff need to periodically replenish feed to feed cylinder 41 using a small boat. Furthermore, the axial-flow turbine 3 does not have a power generation component; only the hydraulic drive component is retained.

[0022] In this optional embodiment, by installing the submersible pump 2 inside the pond 100, and since the axial-flow turbine 3 is connected to the top of the submersible pump 2, the axial-flow turbine 3 can be positioned above the water surface. The submersible pump 2 then pumps water from the pond 100 into the axial-flow turbine 3. This oxygenates the water in the pond 100, and the oxygenated water is then discharged back into the pond 100, increasing the dissolved oxygen content and providing a suitable living environment for aquatic organisms such as fish and shrimp. Simultaneously, the feed pipe 42 delivers feed from the feed cylinder 41, ensuring that feed is released while aeration is occurring. This ensures that the feed is placed in oxygen-rich water, making it easier for fish and shrimp to find food, thus improving feed utilization and achieving better aquaculture and energy-saving effects.

[0023] like Figure 3 As shown, optionally, the material cylinder 41 includes a cylinder body 411 and a stirring component. The stirring component is disposed inside the cylinder body 411 and is driven to rotate by the main shaft of the axial flow turbine 3.

[0024] like Figure 3 and Figure 4 As shown, the stirring component includes a stirring shaft 412 and a stirring rod 413. One end of the stirring shaft 412 is connected to the main shaft of the axial flow turbine 3, and the other end of the stirring shaft 412 is rotatably connected to the inner top surface of the cylinder 411. The stirring rod 413 is connected to the stirring shaft 412.

[0025] In this optional embodiment, the main shaft of the axial flow turbine 3 can drive the stirring shaft 412 to rotate when it rotates, thereby driving the stirring rod 413 to rotate synchronously, which can stir the bait in the feed cylinder 41, helping to break up and mix the clumps of bait.

[0026] like Figure 3 and Figure 4 As shown, the feeding mechanism 4 also includes a transmission component 43, and the stirring shaft 412 is driven to the feeding pipe 42 through the transmission component 43 so that the bait is conveyed in the feeding pipe 42.

[0027] like Figure 3 and Figure 4 As shown, the feeding pipe 42 includes a pipe body 421 and an auger shaft 422. The auger shaft 422 is disposed inside the pipe body 421. One end of the auger shaft 422 is connected to the transmission member 43, and the other end of the auger shaft 422 is rotatably connected to the inner end face of the pipe body 421 away from the material cylinder 41. The lower circumferential surface of the pipe body 421 is provided with a plurality of feeding holes along its extension direction.

[0028] like Figure 3 and Figure 4 As shown, the transmission component 43 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is mounted on the stirring shaft 412, and multiple driven bevel gears are meshed with the driving bevel gear. The driven bevel gears are mounted on the ends corresponding to the auger spiral shaft 422.

[0029] In this optional embodiment, the tube 421 can extend radially along the feed cylinder 41. When the main shaft of the axial flow turbine 3 rotates, it drives the active bevel gear to rotate. The rotation of the active bevel gear drives multiple driven bevel gears to rotate, thereby driving the corresponding auger spiral shaft 422 to rotate. The auger spiral shaft 422 can not only spin and break up the bait deposited at the bottom of the inner cavity of the feed cylinder 41, but also guide the bait into the tube 421. Then, the auger spiral shaft 422 in the tube 421 can continuously push the bait. During the process of pushing the bait, the bait falls into the pond 100 from the feed hole on the lower circumference of the tube 421. Multiple tubes 421 can transport the bait in different directions, and multiple discharge holes on the lower circumference of each tube 421 can put the bait into different positions in the pond 100, thereby increasing the feeding range and improving the feeding effect.

[0030] like Figure 1 and Figure 2As shown, the energy-saving aquaculture aeration and feeding integrated equipment also includes a water pumping pipe 1. The water pumping pipe 1 includes a slanted support pipe 11 and a connecting pipe 12. Multiple slanted support pipes 11 are arranged around the circumference of the submersible pump 2 and are inclined relative to the submersible pump 2. Adjacent water pumping pipes 1 are connected by the connecting pipe 12. The top of multiple slanted support pipes 11 is connected to the water inlet of the submersible pump 2.

[0031] like Figure 1 and Figure 2 As shown, the energy-saving aquaculture aeration and feeding integrated equipment also includes a water delivery pipe and a spiral pipe. One end of the water delivery pipe is connected to the outlet of the submersible pump 2, and the other end of the water delivery pipe is connected to the spiral pipe. The spiral pipe is provided with multiple water spray holes along its extension direction, and the water spray holes face the runner of the axial flow turbine 3.

[0032] In this optional embodiment, the bottom end of the inclined support pipe 11 is designed as a sealed structure, which facilitates insertion into the mud at the bottom of the pond 100. Multiple water suction holes can be provided on the inclined support pipe 11 and the connecting pipe 12. The pumping pipe 1 can pump water from different positions and depths in the pond 100. The water is then pumped into the inlet of the submersible pump 2 through the pumping pipe 1, and then sent from the outlet of the submersible pump 2 through the water delivery pipe into the spiral pipe. The spray holes on the spiral pipe spray water toward the impeller of the axial flow turbine 3, so that the water in the pond 100 can fully contact the air, thereby making the dissolved oxygen content in the water of the entire pond 100 more evenly distributed, providing a more suitable living environment for the aquaculture of fish, shrimp and other aquatic organisms.

[0033] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
