Description

Technical Field

[0001] This utility model relates to the field of fish fry hatching technology, specifically to a fish fry hatching oxygenation device. Background Technology

[0002] The application of novel aeration devices for fish fry hatching not only improves the growth environment of fish fry and reduces losses caused by oxygen deficiency during hatching, but also enhances the economic benefits of aquaculture. With the maturation of technology and the reduction of costs, these aeration devices have a very broad application prospect in aquaculture, especially in improving hatching success rates and fish fry survival rates, where they have significant practical implications.

[0003] Patent specification CN 219835076 U discloses a fish fry hatching and oxygenation device. It comprises several floats arranged in a circular pattern, with mounting plates between them. An impeller is rotatably connected to the lower end of each mounting plate, and the mounting plate and floats are connected by connecting rods. A collar is fixedly mounted on the side wall of the connecting rod, and a plug rod is slidably connected inside the collar. A wind cup is mounted on the upper end of the plug rod via the mounting rod. By opening the connecting cover on one of the floats and simultaneously opening the valve on the connecting pipe, water is injected into the float. The water is distributed among the floats through the connecting pipe, causing the floats to sink. The depth of sinking can be accurately determined by the scale on the outer wall of the float, thus facilitating the adjustment of the impeller's insertion depth into the water.

[0004] However, in implementing the relevant technology, the above-mentioned fish fry hatching and oxygenation device has the following problems: the device cannot oxygenate and filter impurities in the water during use, and it may tilt when measuring the liquid level, resulting in inaccurate measurement results. Therefore, we have proposed a fish fry hatching and oxygenation device. Utility Model Content

[0005] This invention proposes a fish fry hatching and oxygenation device, which solves the problems in related technologies that cannot oxygenate and filter impurities in the water, and that the measurement results may be inaccurate due to tilting when measuring the liquid level.

[0006] The technical solution of this utility model is as follows:

[0007] A fish fry hatching and oxygenation device includes a water tank, a sealed hatch, and a mounting block. A water pump is installed at the top of the water tank, with one end of the pump connected to a suction pipe. One end of the suction pipe extends through the outer wall of the water tank to the inner wall. A dissolved oxygen tank is located on the side of the water tank. The output end of the water pump is connected to a drain pipe, one end of which extends through the outer wall of the dissolved oxygen tank and connects to a dissolved oxygen pipe. A nutrient pump is installed at the top of the dissolved oxygen tank, with its output end extending through the outer wall of the dissolved oxygen tank and connecting to an oxygen injection pipe. One end of the oxygen injection pipe is connected to the dissolved oxygen pipe. A mounting bracket is provided on the inner wall of the dissolved oxygen tank, and a nozzle is mounted on the dissolved oxygen tank via the mounting bracket. The nozzle is connected to one end of the dissolved oxygen pipe. The oxygen tank has symmetrically arranged mounting blocks on its outer wall. Each mounting block has an electric cylinder mounted on its outer wall. The output end of the electric cylinder is connected to a sealed door via a transmission block. A filter plate is installed on the inner wall of the sealed door. A sealing groove is provided on the side wall of the dissolved oxygen tank. The sealed door is movably mounted on the inner wall of the sealing groove. A drive motor is installed at the bottom of the dissolved oxygen tank. The output end of the drive motor passes through the outer wall of the dissolved oxygen tank and is connected to a rotating shaft. A stirring blade is installed on the outer wall of the rotating shaft. A return pipe is installed at the bottom of the dissolved oxygen tank. The end of the return pipe furthest from the dissolved oxygen tank is connected to the bottom of a water tank. A one-way flow valve is installed on the outer wall of the return pipe. A control panel is located on the outer wall of the dissolved oxygen tank.

[0008] Preferably, the outer wall of the water tank is uniformly provided with sliding cylinders, and a measuring column is movably installed in the water tank through the sliding cylinders. One end of the measuring column extends into the interior of the water tank and is equipped with a float.

[0009] Preferably, the outer wall of the measuring column is connected by a connecting frame, and the floats are distributed in an equilateral triangle inside the water tank.

[0010] Preferably, the slide is cylindrical, and the inner diameter of the slide is the same as the outer diameter of the measuring column.

[0011] Preferably, a limiting block is provided at the bottom end of the measuring column, and the outer diameter of the limiting block is larger than the inner diameter of the sliding cylinder.

[0012] Preferably, the dissolved oxygen tubes are evenly distributed in a spiral shape inside the dissolved oxygen tank, and the dissolved oxygen tubes are made of flexible flexible tubing.

[0013] Preferably, the sealed hatch has an arc-shaped structure, and the sealed hatch fits into the sealing groove.

[0014] Preferably, the filter plate has a conical structure, and filter holes are evenly distributed on the outer wall of the filter plate.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, by means of a pump, a water pump, and an oxygenation pipe, when oxygenation of the fish fry in the tank is required, the pump and the water pump are simultaneously activated via the control panel. The pump draws in external oxygen and injects it into the dissolved oxygen pipe through the oxygenation pipe. At the same time, the water pump draws water from the tank through the suction pipe. The bottom of the suction pipe is equipped with a filter hole to prevent the fish fry from being drawn into the suction pipe. Simultaneously, the water is injected into the dissolved oxygen pipe through the drain pipe to mix with the oxygen. Because the dissolved oxygen pipe is spiral-shaped, it allows the water to have maximum contact with oxygen for dissolved oxygenation. The dissolved oxygen liquid is sprayed onto the top of the filter plate through the nozzle. The filter plates have evenly spaced filter holes on their outer wall to filter impurities in the water flow. The filtered water flows into the bottom of the dissolved oxygen tank. The drive motor is turned on to rotate the shaft and stirring blades. The stirring blades agitate the water to increase the oxygen-water mixing rate. The one-way flow valve is opened to allow the dissolved oxygen water to re-enter the tank, thus continuously filtering and oxygenating the water flow. This structure can quickly dissolve oxygen in the water to achieve the effect of oxygenation, while also filtering impurities from the water.

[0017] 2. In this utility model, the sealed chamber, measuring column, and sliding cylinder are designed so that when the filter plate needs to be cleaned, the electric cylinder is opened to push the sealed chamber, causing the sealed chamber to move the filter plate out from the side of the dissolved oxygen tank for cleaning. When it is necessary to detect the water level inside the tank, the tank is equipped with floats that are connected in a triangular shape by a connecting frame. The sliding cylinder limits the measuring column, allowing the measuring column to rise or fall vertically as the liquid level rises or falls, driven by the buoyancy of the floats. Since the measuring column is at the same height as the tank cavity, the distance the measuring column moves out of the tank is the liquid level. This structure allows for real-time observation of the liquid level, enabling consideration of whether water needs to be added to the tank. This structure facilitates the disassembly and cleaning of the filter plate and allows for real-time observation of the water level in the tank, making it convenient to use.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: As Figures 1-5 As shown, this embodiment proposes a fish fry hatching and oxygenation device, including a water tank 1, a sealed door 3, and a mounting block 5. A water pump 10 is installed at the top of the water tank 1, and one end of the water pump 10 is connected to a liquid extraction pipe 11. One end of the liquid extraction pipe 11 penetrates the outer wall of the water tank 1 and extends to the inner wall of the water tank 1. A dissolved oxygen tank 2 is provided on the side of the water tank 1. The output end of the water pump 10 is connected to a liquid return pipe 9, and one end of the liquid return pipe 9 penetrates the outer wall of the dissolved oxygen tank 2 and is connected to a dissolved oxygen pipe 16. A pumping pump 8 is installed at the top of the dissolved oxygen tank 2, and the output end of the pumping pump 8 penetrates the outer wall of the dissolved oxygen tank 2 and is connected to an oxygen injection pipe 15. One end of the oxygen injection pipe 15 is connected to the dissolved oxygen pipe 16. A mounting bracket 19 is provided on the inner wall of the dissolved oxygen tank 2, and a nozzle 20 is installed on the dissolved oxygen tank 2 through the mounting bracket 19. The nozzle 20 is connected to the dissolved oxygen pipe 16. One end is connected, and the outer wall of the dissolved oxygen tank 2 is symmetrically provided with mounting blocks 5. Each mounting block 5 is equipped with an electric cylinder 6. The output end of the electric cylinder 6 is connected to the sealed door 3 through the transmission block 4. The inner wall of the sealed door 3 is equipped with a filter plate 26. The side wall of the dissolved oxygen tank 2 is provided with a sealing engagement groove 22. The sealed door 3 is movably installed on the inner wall of the sealing engagement groove 22. The bottom end of the dissolved oxygen tank 2 is equipped with a drive motor 23. The output end of the drive motor 23 passes through the outer wall of the dissolved oxygen tank 2 and is connected to a rotating shaft 24. The outer wall of the rotating shaft 24 is equipped with a stirring blade 25. The bottom end of the dissolved oxygen tank 2 is equipped with a return pipe 17. The end of the return pipe 17 away from the dissolved oxygen tank 2 is connected to the bottom end of the water tank 1. The outer wall of the return pipe 17 is equipped with a one-way flow valve 18. The outer wall of the dissolved oxygen tank 2 is equipped with a control panel 7.

[0027] In this embodiment, the dissolved oxygen tubes 16 are evenly distributed in a spiral shape inside the dissolved oxygen tank 2, and the dissolved oxygen tubes 16 are made of elastic flexible tubes.

[0028] In this embodiment, the sealed hatch 3 has an arc-shaped structure, and the sealed hatch 3 fits into the sealing engagement groove 22.

[0029] In this embodiment, the filter plate 26 has a conical structure, and filter holes are evenly distributed on the outer wall of the filter plate 26.

[0030] Specific examples Figure 1 , Figure 2 and Figure 4 As shown, when using this structure, to oxygenate the fish fry in tank 1, the pump 8 and water pump 10 are simultaneously activated via control panel 7. Pump 8 draws in external oxygen through oxygen injection pipe 15 into dissolved oxygen pipe 16. Simultaneously, water pump 10 draws water from tank 1 through suction pipe 11. Suction pipe 11 has filter holes at its bottom to prevent fish fry from being drawn into it. Water is then injected into dissolved oxygen pipe 16 through drain pipe 9 to mix with oxygen. Because dissolved oxygen pipe 16 is spiral-shaped, it maximizes the contact between water and oxygen for dissolved oxygenation. The liquid is sprayed onto the top of the filter plate 26 through the nozzle 20. The filter plates 26 have evenly arranged filter holes on their outer walls to filter impurities in the water flow. The filtered water flows into the bottom of the dissolved oxygen tank 2. The drive motor 23 is turned on to drive the rotating shaft 24 and the stirring blade 25 to rotate. The stirring blade 25 stirs the water to increase the oxygen-water mixing rate. The one-way flow valve 18 is opened to allow the dissolved oxygen water to re-enter the interior of the water tank 1, thereby achieving the effect of continuously filtering and oxygenating the water flow. This structure can quickly dissolve oxygen in the water to achieve the effect of oxygenation, while also filtering impurities in the water.

[0031] Example 2: The outer wall of the water tank 1 is uniformly provided with sliding cylinders 14. The water tank 1 is movably installed with a measuring column 12 through the sliding cylinders 14. One end of the measuring column 12 extends into the interior of the water tank 1 and is equipped with a float ball 21.

[0032] In this embodiment, the outer wall of the measuring column 12 is connected by a connecting frame 27, and the floats 21 are distributed in an equilateral triangle inside the water tank 1.

[0033] In this embodiment, the slide 14 is cylindrical, and the inner diameter of the slide 14 is the same as the outer diameter of the measuring column 12.

[0034] In this embodiment, a limiting block 13 is provided at the bottom end of the measuring column 12, and the outer diameter of the limiting block 13 is larger than the inner diameter of the slide cylinder 14.

[0035] Specific examples Figure 1 , Figure 3 and Figure 5As shown, when using this structure, to clean the filter plate 26, the electric cylinder 6 is opened to push the sealed door 3, causing the sealed door 3 to move the filter plate 26 out from the side of the dissolved oxygen tank 2 for cleaning. When it is necessary to detect the water level inside the water tank 1, since the water tank 1 is equipped with a float ball 21, and the float ball 21 is connected in a triangular distribution through the connecting frame 27, and the limiting effect of the sliding cylinder 14 on the measuring column 12 allows the measuring column 12 to rise or fall vertically through the buoyancy of the float ball 21 when the liquid level drops or rises. Since the measuring column 12 is at the same height as the inner cavity of the water tank 1, the distance that the measuring column 12 moves out of the water tank 1 is the height of the liquid level. This structure allows for real-time observation of the liquid level, allowing consideration of whether water needs to be added to the water tank 1. This structure facilitates the disassembly and cleaning of the filter plate 26 and allows for real-time observation of the water level in the water tank 1, making it convenient to use.

[0036] Working Principle: When oxygenation is needed for the fish fry in tank 1, the pump 8 and water pump 10 are simultaneously activated via control panel 7. Pump 8 draws in external oxygen through oxygen injection pipe 15 into dissolved oxygen pipe 16. Simultaneously, water pump 10 draws water from tank 1 through liquid extraction pipe 11. The bottom of liquid extraction pipe 11 has filter holes to prevent fish fry from being drawn into it. Water is then injected into dissolved oxygen pipe 16 through liquid return pipe 9 to mix with oxygen. The spiral shape of dissolved oxygen pipe 16 maximizes water contact with oxygen for dissolved oxygenation. The dissolved oxygen liquid is sprayed through nozzle 20 onto the filter plate 26. The filter holes evenly distributed on the outer wall of filter plate 26 filter impurities from the water flow. The filtered water flows to the bottom of dissolved oxygen tank 2. The drive motor 23 is activated, rotating shaft 24 and stirring blade 25. The stirring blade 25 agitates the water, increasing the oxygen-water mixing rate. The one-way flow valve 18 is opened, allowing the dissolved oxygenated water to re-enter tank 1. This system continuously filters and oxygenates the water flow. When cleaning the filter plate 26 is required, the electric cylinder 6 is opened to push the sealed door 3, causing the sealed door 3 to move the filter plate 26 out from the side of the dissolved oxygen tank 2 for cleaning. When it is necessary to detect the water level inside the water tank 1, since the water tank 1 is equipped with floats 21, and the floats 21 are connected in a triangular shape by the connecting frame 27, and the limiting effect of the sliding cylinder 14 on the measuring column 12 allows the measuring column 12 to rise or fall vertically by the buoyancy of the floats 21 when the liquid level drops or rises. Since the measuring column 12 is at the same height as the inner cavity of the water tank 1, the distance that the measuring column 12 moves out of the water tank 1 is the height of the liquid level. This structure allows for real-time observation of the liquid level, allowing for consideration of whether water needs to be added to the water tank 1. This device can quickly dissolve oxygen in the water and remove impurities from the water, while facilitating the cleaning of the filter plate 26 and allowing for real-time observation of the water level in the water tank 1. It is convenient to use.
