Description

Technical Field

[0001] This utility model belongs to the technical field of oxygenation devices, and in particular relates to an oxygenation device for sea bass farming. Background Technology

[0002] Currently, the mainstream oxygenation methods for sea bass farming mostly rely on oxygen pumps to blow air into the water, but these methods have obvious shortcomings.

[0003] On the one hand, during the oxygenation process in water bodies, the contact between air and water is mostly limited to the surface. This contact method has significant limitations: firstly, the gas and liquid phases can only form limited contact on the surface of the water, resulting in a serious lack of effective contact area; secondly, the limited contact area directly restricts the oxygenation efficiency, causing the actual oxygenation amount per unit time to be far lower than the theoretical value, ultimately making it difficult to meet the overall oxygenation requirements. More importantly, under the surface contact mode, a large amount of oxygen is lost with the airflow before it can dissolve, further leading to low oxygen resource utilization, which increases energy consumption costs and reduces the overall efficiency of the oxygenation system. Utility Model Content

[0004] The purpose of this invention is to provide an oxygenation device for bass farming. Driven by a motor, an impeller rotates, drawing lake water from the filter screen upwards into the oxygenation hood cavity. The lake water is then transported upwards by spiral blades, mixing thoroughly with oxygen blown from the inner wall of the oxygenation hood. The mixed lake water is discharged from the top of the oxygenation hood, flows into a drainage chamber, and is then discharged through a one-way valve. This invention solves the problem that in existing water oxygenation processes, the contact between air and water is mostly limited to the surface layer. This contact method has significant limitations: firstly, the gas and liquid phases can only form limited contact on the water surface, resulting in a severely insufficient effective contact area; secondly, the limited contact area directly restricts the oxygenation efficiency, causing the actual oxygenation amount per unit time to be far lower than the theoretical value, ultimately making it difficult to meet the overall oxygenation requirements. More importantly, in the surface contact mode, a large amount of oxygen escapes with the airflow before dissolving, further leading to low oxygen resource utilization, increasing energy costs and reducing the overall efficiency of the oxygenation system.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an oxygenation device for sea bass farming, comprising a solar panel and an oxygen dissolving mechanism. The oxygen dissolving mechanism is located below the solar panel and includes a lifting assembly located below the solar panel, and a stirring assembly located below the lifting assembly. The stirring assembly includes a drainage chamber located below the solar panel. An oxygen supply hood is fixedly connected to the top of the drainage chamber, extending through the bottom of the drainage chamber and downwards. An oxygenation component is installed inside the cavity of the oxygen supply hood. The top of the oxygen supply hood has three openings for drainage, and the inner wall of the oxygen supply hood has a partition for supplying oxygen. Several one-way valves are installed on the outer surface of the drainage chamber.

[0007] Furthermore, three buoyancy balls are installed below the solar panel, and an oxygenator is installed on top of the drainage chamber to supply oxygen to the entire device.

[0008] Furthermore, the lifting assembly includes a protective cover slidably connected to the outer ring of the drainage chamber. A pull rod is disposed inside the cavity of the protective cover 1. The pull rod 1 is rotatably connected to the inner edge of the protective cover 1 via a shaft. A motor is fixedly connected to the protective cover 1. The left output end of the motor 1 passes through the protective cover 1 and is fixedly connected to the inner shaft of the pull rod 1 via a coupling. The motor 1 provides driving force to the pull rod 1. A pull rod 2 is connected to the end of the pull rod 1 away from the shaft via a pin. A fixed bracket is connected to the end of the pull rod 2 away from the pull rod 1 via a pin. The bottom of the fixed bracket is fixedly connected to the top of the drainage chamber. The pull rod 2 is used to convert rotational force into lifting force. Two sliding grooves are formed on the inner wall of the protective cover 1. Two sliders are fixedly connected to the outer surface of the drainage chamber. The outer surfaces of the two sliders are respectively in contact with the inner walls of the sliding grooves. The two sliding grooves and sliders are symmetrically designed. The two sliders are used to limit the movement of the drainage chamber.

[0009] Furthermore, the oxygenation component includes a second motor fixedly connected to the top of the drainage chamber. The bottom output end of the second motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft is located inside the oxygen supply hood cavity, passing through the top of the drainage chamber and extending to the bottom of the oxygen supply hood.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model incorporates a stirring assembly, specifically a motor-driven impeller rotation, which draws lake water entering through the filter screen from bottom to top into the oxygen supply hood cavity. The lake water is then transported upwards by the spiral blades, where it mixes thoroughly with oxygen blown out from the inner wall of the oxygen supply hood. The mixed lake water is then discharged from the top of the oxygen supply hood, flows into the drainage chamber, and is then discharged through a one-way valve. The forced mixing of lake water and oxygen expands the gas-liquid contact area, allowing oxygen to dissolve into the water more quickly and evenly.

[0012] 2. This utility model uses a lifting component, specifically a motor that is started, which drives a pull rod to rotate. The rotation of the pull rod drives a pull rod to reciprocate. The movement of the pull rod drives the drainage chamber to slide up and down along the chute, which can cover waters of different depths and is suitable for complex scenarios where lake water is low in dissolved oxygen at various depths.

Located within the oxygen supply hood 228 cavity, a rotating shaft 223 penetrates the top of the drainage chamber 221 and extends to the bottom of the oxygen supply hood 228. The outer surface of the rotating shaft 223 is rotatably connected to the inner edge of the protective cover 211. A spiral blade 224 contacts the inner wall of the oxygen supply hood 228. The inner ring of the spiral blade 224 is fixedly connected to the outer surface of the rotating shaft 223. A motor 222 provides driving force to the spiral blade 224.

The inside of the scraper 227 is fixedly connected to the outer surface of the rotating shaft 223. The scraper 227 is used to clean the filter screen 226. The lake water and oxygen are forcibly mixed, which expands the gas-liquid contact area and makes the oxygen integrate into the water faster and more evenly.

[0025] Three buoyancy balls 112 are installed below the solar panel 111, and an oxygenator 113 is installed on the top of the drainage tank 221. The oxygenator 113 supplies oxygen to the whole device.

[0026] The lifting assembly 21 includes a protective cover 211 slidably connected to the outer ring of the drainage chamber 221. A pull rod 213 is disposed inside the cavity of the protective cover 211. The pull rod 213 is rotatably connected to the inner edge of the protective cover 211 via a shaft.

The two grooves 216 and the sliders 217 are symmetrically designed, and the two sliders 217 are used to limit the drainage chamber 221.

[0029] A specific application of this embodiment is as follows: When using the device, the operator places it in the lake and simultaneously starts motor 222 and aerator 113. The aerator has a built-in small motor that drives an eccentric wheel or diaphragm to move, causing the volume of the air chamber inside the air pump to change periodically. When the volume of the air chamber increases, a negative pressure is created inside, and the air intake, which usually has a filter, reduces the amount of dust entering the air. When the volume of the air chamber decreases, the air is compressed, and the pressure increases. The compressed air is then transported through a silicone tube or plastic hose to underwater bubble diffusers such as bubble stones, bubble strips, or sponges. These devices have numerous tiny pores on their surfaces, typically 0.1-1 mm in diameter, through which compressed air flows. Released from the pores of the diffuser, a large number of tiny bubbles are formed. The bubbles rise slowly in the water, and during the rise, they come into full contact with the surrounding water. Oxygen gradually dissolves into the water through the gas-liquid interface. After the motor 222 is started, it drives the impeller 225 to rotate. Under the rotation of the impeller 225, the lake water entering from the filter screen 226 is drawn from bottom to top into the oxygen supply hood 228 cavity, and is transported upward by the rotation of the spiral blades 224. During the transport process, it will be fully mixed with the oxygen blown out from the inner wall of the oxygen supply hood 228. When the lake water flows to the top of the oxygen supply hood 228, it will be discharged from the opening and flow into the drainage chamber 221 cavity, and then discharged outward through the one-way valve on the outer surface of the drainage chamber 221.

[0030] When dissolved oxygen is insufficient at different depths at the bottom of the lake, the staff can start motor 212. Motor 212 will drive lever 213 to rotate. Lever 213 rotates and drives lever 214 to reciprocate. The movement of lever 214 drives the drainage chamber 221 to slide up and down along the chute 216. To improve the continuity of the equipment, a solar panel 111 is installed above it. Sunlight passes through the surface and reaches the PN junction. Photons with sufficient energy excite electrons in silicon, generating free electrons and holes. The built-in electric field of the PN junction pushes electrons to the N region and holes to the P region. After connecting external loads such as batteries and electrical appliances, electrons in the N region flow to the P region through the external circuit, and holes move inside the semiconductor.

[0031] It should be noted that the control of the aerator 113, solar panel 111, motor 1 212 and motor 222 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
