Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, specifically to an oxygenation device for marine aquaculture. Background Technology

[0002] In marine aquaculture, the dissolved oxygen content in the water is one of the key factors affecting the survival and growth of cultured organisms. When the dissolved oxygen in the water is insufficient, it will lead to oxygen deficiency in cultured organisms, and even cause large-scale mortality, resulting in huge economic losses for aquaculture farmers. Therefore, oxygenation equipment is an important component of marine aquaculture systems, and its performance is directly related to the aquaculture benefits.

[0003] Currently, commonly used aeration equipment for marine aquaculture mainly includes various types such as impeller aerators, jet aerators, and aeration aerators. Among them, aeration aerators are widely used in the field of marine aquaculture due to their advantages such as high oxygenation efficiency and low energy consumption. This type of equipment usually uses a blower to force air into the aeration pipe, and then the aeration pipe releases the air into the water in the form of bubbles. Oxygen transfer is achieved through the contact between the bubbles and the water.

[0004] The prior art patent document CN220823843U discloses an oxygenation device for marine aquaculture production. This device can connect and seal the upper and lower shells through the cooperation between the external and internal threads, which facilitates water pumping. The solar panel of the glass shell can effectively prevent water from getting wet. The water distribution block can spray the water from the water outlet pipe through the water distribution port, spreading the water flow in all directions, which can facilitate the absorption of more oxygen into the air. The water-absorbing ball made of stainless steel can sink in water and will not be corroded or rusted by water, thus affecting the operation of the water-absorbing ball.

[0005] While the aforementioned existing technologies possess basic oxygenation functions and a certain degree of structural detachability, they primarily achieve oxygenation through water flow and air contact, lacking the ability to adjust the aeration position based on water depth. Consequently, they are ill-suited to the needs of different aquaculture scenarios. Therefore, we require an oxygenation device for marine aquaculture. Utility Model Content

[0006] The purpose of this invention is to provide an oxygenation device for marine aquaculture to solve the problem mentioned in the background art of not having the function of adjusting the aeration position according to the water level depth.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an oxygenation device for seawater aquaculture, including a support frame, the inner wall of the support frame having a through groove, and a winding assembly being provided at the top of the support frame, and a blower being fixedly installed at the top of the support frame; The winding assembly includes a mounting plate and a guide rod. A servo motor is fixedly mounted on the outer wall of the mounting plate. The output shaft of the servo motor is fixedly connected to a rotating rod via a coupling. A winding reel is fixedly connected to the outer wall of the rotating rod. A base is slidably connected to the outer wall of the guide rod. A T-shaped frame is fixedly connected to the top of the base. A ring is fixedly connected to the top of the T-shaped frame. A protective component is provided on the outer side of the T-shaped frame. The protective assembly includes an aeration pipe and a protective cylinder. Threaded seats are fixedly connected to both sides of the T-shaped frame, and the protective cylinder is threadedly connected to the threaded seats through external threads. A protective net is fixedly connected to the outer side of the protective cylinder.

[0008] Preferably, the air outlet of the blower is fixedly connected to an L-shaped pipe, and the air outlet of the L-shaped pipe is fixedly connected to a long flexible hose via a flange, with a connector fixedly connected to one end of the long flexible hose.

[0009] Preferably, the inner wall of the winding reel is wound with a rope, and one end of the rope is fixed to a ring. The rope is made of stainless steel wire rope.

[0010] Preferably, there are four guide rods, which are arranged in a rectangular shape and fixed to the bottom of the support frame. Each of the four guide rods has a limiting block at its bottom end. The inner wall of the base has four guide holes, and the guide rods pass through the four guide holes respectively.

[0011] Preferably, one end of the aeration pipe extends into the threaded seat and is fixed to the T-shaped frame with bolts. The aeration pipe has multiple aeration holes and a threaded interface.

[0012] Preferably, the protective cylinder is cylindrical, and a hollow tube is fixedly connected to the inner wall of the protective cylinder. One end of the connector passes through the hollow tube and is connected to the threaded interface on the aeration pipe.

[0013] Preferably, the outer wall of the protective cylinder is fixedly connected to two fixed handles, and the two fixed handles are symmetrically arranged on the protective cylinder.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this utility model, by incorporating a winding assembly, allows for flexible adjustment of the aeration position to adapt to different water depth requirements. When the servo motor drives the rotating rod to rotate the winding reel, the stainless steel wire rope wound around the reel can pull the T-shaped frame and protective assembly up and down along the guide rod via the ring. The cooperation between the four guide rods and the guide holes in the base ensures stability during lifting and lowering, preventing deviation. Aquaculture farmers can control the position of the aeration pipe in the water according to actual needs such as the depth of the aquaculture water and the activity layer of the aquatic organisms, allowing oxygen to be directly delivered to the concentrated area of ​​the aquatic organisms, improving oxygen utilization and targeted aeration.

[0015] Secondly, this utility model can effectively block impurities such as uneaten feed, feces, and algae from entering the aeration pipe by setting a protective net on the outside of the protective cylinder, thus avoiding the decrease in oxygenation efficiency caused by the blockage of the aeration holes. The protective components can be raised to the water surface by working with a servo motor. The operator can easily disassemble the protective cylinder for cleaning by turning the fixed handle. At the same time, it is also convenient to inspect, clean or replace the internal aeration pipe. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 As shown, an oxygenation device for seawater aquaculture includes a support frame 1, a through groove 2 on the inner wall of the support frame 1, a winding assembly 3 on the top of the support frame 1, and a blower 5 fixedly installed on the top of the support frame 1. The winding assembly 3 includes a mounting plate 301 and a guide rod 306. A servo motor 302 is fixedly mounted on the outer wall of the mounting plate 301. The output shaft of the servo motor 302 is fixedly connected to a rotating rod 303 via a coupling. A winding reel 304 is fixedly connected to the outer wall of the rotating rod 303. A base 308 is slidably connected to the outer wall of the guide rod 306. A T-shaped frame 310 is fixedly connected to the top of the base 308. A ring 311 is fixedly connected to the top of the T-shaped frame 310. A protective assembly 4 is provided on the outer side of the T-shaped frame 310. The protective component 4 includes an aeration pipe 402 and a protective cylinder 403. Threaded seats 401 are fixedly connected to both sides of the T-shaped frame 310, and the protective cylinder 403 is threadedly connected to the threaded seat 401 through an external thread 405. A protective net 404 is fixedly connected to the outside of the protective cylinder 403.

[0020] Through the above technical solution, the support frame 1 is provided with mounting holes, which facilitates the fixing of the support frame 1 with bolts. The support frame 1 serves as the basic support structure of the equipment. The through groove 2 opened in its inner wall provides room for the rope 305 to move, avoiding interference between the component and the support frame 1 during operation. Through the coordinated cooperation of the winding assembly 3 and the protective assembly 4, the aeration position can be flexibly adjusted, and the core aeration component can be effectively protected. The blower 5 provides a stable air source power for the entire oxygenation system. The support frame 1 is equipped with a control box to facilitate the operation of the control device.

[0021] Specifically, the air outlet of the blower 5 is fixedly connected to an L-shaped pipe 6, and the air outlet of the L-shaped pipe 6 is fixedly connected to a long flexible hose 7 via a flange, with a connector 8 fixedly connected to one end of the long flexible hose 7.

[0022] Through the above technical solutions, the L-shaped pipe 6 can change the direction of the airflow output by the blower 5, so that the airflow changes from horizontal to downward conveying, which is compatible with the overall layout of the equipment and avoids the pipeline from conflicting with other components; the flange connection method can ensure the sealing performance between the air outlet of the L-shaped pipe 6 and the long hose 7, prevent the reduction of oxygenation efficiency caused by airflow leakage, and facilitate the disassembly and maintenance of the pipeline in the future; the long hose 7 is reserved with sufficient length, and the flexibility of the long hose 7 allows it to move accordingly with the lifting and lowering of the protective cylinder 403, avoiding the pipeline from being pulled and broken due to component movement, while the connector 8 realizes the connection between the long hose 7 and the aeration pipe 402, providing a stable channel for airflow delivery.

[0023] Specifically, a rope 305 is wound around the inner wall of the winding reel 304, and one end of the rope 305 is fixed to the ring 311. The rope 305 is made of stainless steel wire rope.

[0024] Through the above technical solution, the winding reel 304 rotates to wind up and unwind the rope 305, thereby pulling the T-shaped frame 310 up and down; the ring 311, as the connection point between the rope 305 and the T-shaped frame 310, can evenly transmit the tension of the rope 305 to the T-shaped frame 310; the stainless steel wire rope 305 has high strength and corrosion resistance, can withstand long-term corrosion in the seawater environment, prevent the rope 305 from rusting and breaking, and ensure the safety and service life of the equipment.

[0025] Specifically, there are four guide rods 306, which are arranged in a rectangular shape and fixed to the bottom of the support frame 1. Each of the four guide rods 306 has a limiting block 307 at its bottom end. The inner wall of the base 308 has four guide holes 309, and the guide rods 306 pass through the four guide holes 309 respectively.

[0026] Through the above technical solution, the four guide rods 306 and the guide holes 309 of the base 308 form a sliding fit, providing guidance for the lifting and lowering of the base 308 and the T-shaped frame 310, ensuring that the base 308 remains stable during movement. The limiting block 307 at the bottom of the guide rod 306 can limit the lowest sliding position of the base 308, preventing the base 308 from slipping off the guide rod 306, avoiding damage to equipment parts or sinking into the water, and further ensuring the safe operation of the equipment. The base 308 has a counterweight block inside, which makes it easy for the base 308 to sink into the seawater of the aquaculture by its own weight.

[0027] Specifically, one end of the aeration pipe 402 extends into the threaded seat 401 and is fixed to the T-shaped frame 310 by bolts. The aeration pipe 402 has multiple aeration holes and a threaded interface.

[0028] Through the above technical solution, the aeration pipe 402 can be fixed to the T-shaped frame 310 by using bolts, preventing the aeration pipe 402 from loosening or shifting when the seawater flows or the equipment is running. At the same time, it is convenient to disassemble and replace the aeration pipe 402 later. Multiple aeration holes can disperse the airflow delivered by the blower 5 into fine bubbles, increase the contact area between air and seawater, improve the oxygen dissolution efficiency in seawater, and ensure that the aquaculture water body obtains sufficient oxygen. The threaded interface provides convenience for the connection between the aeration pipe 402 and the connector 8, making it easy for the connector 8 to be installed on the threaded interface.

[0029] Specifically, the protective cylinder 403 is cylindrical, and a hollow tube 407 is fixedly connected to the inner wall of the protective cylinder 403. One end of the connector 8 passes through the hollow tube 407 and is connected to the threaded interface on the aeration pipe 402.

[0030] Through the above technical solution, the cylindrical protective tube 403 can form a full-round protective enclosure for the internal aeration pipe 402, reducing the direct contact of seawater impurities with the aeration pipe 402; the hollow tube 407 provides a passage for the connector 8 to pass through, ensuring that the connector 8 can be connected to the threaded interface of the aeration pipe 402, and the inner wall of the hollow tube 407 fits against the outer wall of the connector 8, making the gap between the hollow tube 407 and the connector 8 smaller, preventing aquaculture products from entering through the gap.

[0031] Specifically, the outer wall of the protective cylinder 403 is fixedly connected to two fixed handles 406, and the two fixed handles 406 are symmetrically arranged on the protective cylinder 403.

[0032] Through the above technical solution, the symmetrically arranged fixed handles 406 provide operators with convenient force points for disassembling or installing the protective cylinder 403. The protective cylinder 403 can be easily rotated without the need for additional tools to achieve threaded connection or separation with the threaded seat 401, thereby reducing the intensity of manual operation and improving equipment maintenance efficiency.

[0033] In use, first connect the device to an external power supply to provide power. Install and fix the support frame 1 in a suitable position in the seawater aquaculture area, such as the edge of the aquaculture pond or a pre-set fixed base, ensuring that the support frame 1 is stable and will not tilt due to seawater fluctuations. Based on the required depth of the aquaculture water and the activity layer of the aquatic organisms, start the servo motor 302, driving the rotating rod 303 to rotate the winding reel 304, releasing the wound rope 305. Under gravity, the base 308 slides downwards along the guide rod 306, causing the T-shaped frame 310 and protective components 4 to descend synchronously until the aeration pipe 402 reaches the target water level. If it is necessary to increase the depth of the aeration pipe 402 in the seawater, operate the servo motor 302 to drive the rotating rod 303 in reverse, causing the winding reel 304 to retract the rope 305, pulling the T-shaped frame 310 and protective components 4 upwards along the guide rod 306. After adjusting to the appropriate position, turn off the servo motor 302. Servo motor 302; When oxygenation is needed, blower 5 is started. Outside air is compressed by blower 5 and enters aeration pipe 402 through L-shaped pipe 6, long hose 7, and connector 8 in sequence. Then, it is dispersed into fine bubbles through multiple aeration holes on aeration pipe 402 and released into seawater. The bubbles fully contact the seawater, complete the oxygen dissolution, and provide sufficient dissolved oxygen for aquaculture organisms. After the equipment has been used for a period of time, if it is necessary to clean or maintain aeration pipe 402, servo motor 302 can be started again to raise T-shaped frame 310 above the water surface. After turning off servo motor 302, the operator can rotate protective cylinder 403 through fixed handle 406 to separate it from threaded seat 401. This allows for the cleaning of impurities attached to the surface of protective net 404, or the inspection and replacement of aeration pipe 402. This completes all the work. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
