Description

Technical Field

[0001] The utility model relates to the technical field of aquatic oxygenators, in particular to an oxygenator used for aquaculture. Background Art

[0002] Oxygenation is an important technical measure in aquaculture, which can increase the dissolved oxygen content in water and promote the growth and reproduction of aquatic organisms. There are several ways to increase oxygen in aquaculture, including mechanical oxygenation, chemical oxygenation and biological oxygenation. Mechanical oxygenation mainly includes water pumps, aerators and blowers microporous pipe oxygenation.

[0003] Microporous pipe oxygenation is a new type of oxygenation method that is worth promoting. Its principle is to send air into the microporous tube through a Roots blower and let the microporous tube release gas in the water. However, since aquatic animals tend to gather in areas with higher oxygen content to more easily obtain sufficient oxygen, the holes for releasing air on the microporous pipe are more likely to attract farmed organisms to gather. Although a certain degree of aggregation may help to observe and manage the health of fish and shrimp, excessive aggregation may also lead to problems of competition and ecological balance.

[0004] After searching, the Chinese utility model patent with the publication number of CN218483575U discloses a fish pond bottom oxygenation device, including a floating raft, a limit rod and a telescopic rod, an air pump is installed on the upper part of the floating raft, an outer tube is installed on the lower part of the floating raft, the air pump and the outer tube are connected, the inner tube is slidably connected to the inner tube, the inner side of the upper part of the outer tube and the inner side of the lower part of the inner tube are fixedly connected with a connecting frame, the connecting frame is respectively installed at the upper and lower ends of the telescopic mechanism, and a rotating mechanism is arranged at the bottom of the inner tube; the rotating mechanism includes a shell, a blade, a bracket, a bottom shell and an exhaust port, and the lower part of the blade is rotatably connected to the middle part of the bracket. The application uses the airflow discharged by the air pump to impact the blade to make the bottom shell with the exhaust port rotate in the water body, so as to expand the oxygenation range, but because aquatic animals in the breeding pond usually gather in places with rich oxygen, although the use of the device can expand the aeration range, it still cannot avoid the problem of the gathering of the cultured organisms at the exhaust port, thus affecting the breeding efficiency, biological health and water environment. Utility Model Content

[0005] In view of the above-mentioned prior art, the utility model provides an oxygenator for aquaculture, and the main technical problem to be solved is how to avoid excessive aggregation of farmed animals while evenly oxygenating the water body.

[0006] To achieve the above purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0025] Example 1

[0026] See attached Figure 1-3The present application provides an oxygenator for aquaculture, comprising an air-inflating tube 1 connected to an air pump, the air-inflating tube 1 being used to inflate air into a water body, the air-inflating tube 1 being in the shape of a figure 7, the horizontal tube body of which is used to dock with the air pump, and the vertical tube body of which is used to be immersed in water to guide the airflow into the water, the air pump can select a Roots blower, so it can have sufficient and appropriate airflow output, a floating block 3 is provided on the outside of the air-inflating tube 1, the floating block 3 is a hollow structure, and can provide a certain support effect for the air-inflating tube 1 through its own buoyancy on the water surface, a driving mechanism is provided inside the floating block 3, and a net tube 4 is provided at the bottom of the floating block 3, the driving mechanism is used to drive the net tube 4 to rotate, and a plurality of vibration units 5 are provided inside the net tube 4, and the net tube 4 can drive the vibration unit 5 to rotate when rotating, so that the vibration unit 5 can hit the bubbles by its own rotation, so that the volume of the bubbles can be reduced, in this case, it can be beneficial for the oxygen in the air in the bubbles to dissolve in the water body, and the vibration The unit 5 comprises a fixing rod 501, which is fixedly connected to the inner wall of the net cylinder 4, and a fixing plate 504 is fixedly connected to one end of the fixing rod 501, a connecting ring 503 is sleeved on the outside of the rod body of the fixing rod 501, and a spring 502 is fixedly connected between the connecting ring 503 and the inner wall of the net cylinder 4 at the outside of the fixing rod 501. When the spring 502 rotates, on the one hand, it will swing left and right due to its own inertia, and on the other hand, it will continue to expand and contract due to the influence of centrifugal force. Therefore, the existence of the spring 502 can not only enhance the effect of breaking the bubbles, but also drive the connecting ring 503, and hit the fixing rod 501 and the fixing plate 504 when swinging and expanding, respectively, so as to induce the vibration of the net cylinder 4, and the net cylinder 4 can transmit the vibration to the water body outside it, and the vibration of the water body can disperse the farmed animals, and avoid them from excessively gathering near the net cylinder 4, resulting in resource competition and other phenomena that affect the farming effect.

[0027] Preferably, a circular opening is provided in the middle of the bottom end of the float 3, and the float 3 is rotatably connected to a turntable 301 at the circular opening. The turntable 301 can be made of hard plastic and can be made into a hollow structure to supplement the buoyancy of the float 3. Circular through holes are provided in the middle of the turntable 301 and the middle of the top of the float 3. The inflation tube 1 passes through the float 3 and the turntable 301 at the two circular through holes respectively, and the inflation tube 1 is fixedly connected to the float 3. A rotating seal can be used between the inflation tube 1 and the turntable 301, so as to ensure the sealing effect of the float 3 without affecting the rotation of the turntable 301 itself.

[0028] Preferably, the mesh tube 4 is fixedly connected to the bottom of the floating block 3, and the mesh tube 4 is located on the outside of the inflation tube 1. The mesh tube 4 can provide a protective effect for the inflation tube 1 without affecting the inflation effect, thereby preventing the underwater environment from causing the air holes of the inflation tube 1 to be blocked and affecting the inflation effect. The inflation tube 1 is located in the mesh tube 4. A plurality of air holes are equidistantly provided on the outside of the tube body, and the inflation tube 1 is fixedly connected with a guide groove 101 at the air hole. The number of vibration units 5 is the same as that of the air holes and corresponds one to one. The vibration unit 5 is located below the guide groove 101. The guide groove 101 is a groove plate with an inverted U-shaped cross-section, and the guide grooves 101 are all fixed on the inflation tube 1 at an angle downward. In this case, the gas discharged from the inflation tube 1 can directly flow to the vibration unit 5, so the rotation of the vibration unit 5 can effectively break the bubbles.

[0029] Preferably, the driving mechanism includes a motor 201, a circular hole is opened on one side of the top of the float 3, and the top of the float 3 is fixedly connected to the casing 2 outside the circular hole, the motor 201 is fixedly connected to the inner wall of the top of the casing 2, the casing 2 can protect the motor 201, so it can avoid splashing water that affects the normal operation of the motor 201, and the output shaft of the motor 201 extends to the inside of the float 3 at the circular hole, the bottom end of the output shaft of the motor 201 is keyed to a gear 202, the turntable 301 is keyed to a gear ring 302 outside the disk of the float 3, the gear ring 302 is meshed with the gear 202, the motor 201 is a servo motor, and since the servo motor can control the speed, the controller can be used to control the motor 201 so that its speed can be changed in real time, and when the speed of the motor 201 is fast or slow, the stable swing and extension of the spring 502 can be guaranteed, and the controller can use an 8051 single-chip microcomputer.

[0030] Preferably, a plurality of stirring rods 6 are equidistantly fixedly connected to the outer side of the inner wall at the bottom end of the mesh tube 4. The stirring rods 6 are in a 7-shape, and the lateral arms of the stirring rods 6 are located below the inflation tube 1. The stirring rods 6 are arranged in a circular array. When the mesh tube 4 rotates, the stirring rods 6 and the inflation tube 1 can be driven to rotate relative to each other. Therefore, the stirring rods 6 can break the gas ejected from the bottom of the inflation tube 1, thereby further ensuring the dissolution efficiency of oxygen in the water.

[0031] Working principle: When using the device, the top of the inflation tube 1 can be connected to the air outlet end of the Roots blower, and then the net tube 4 can be immersed in the water body and the floating block 3 can be kept above the water body, and then the Roots blower and the motor 201 can be started. At this time, the Roots blower can generate airflow and transport it to the inflation tube 1, and then under the action of the guide groove 101, the gas discharged from the air hole can enter the water body downward and form bubbles therein. At the same time, the operation of the motor 201 can drive the gear ring 302 to rotate through the gear 202, and the gear ring 302 drives the net tube 4 to rotate through the turntable 301, and the net tube 4 can drive the vibration unit 5 to rotate, so the vibration unit 5 can break the bubbles, so that the oxygen in the air can be more evenly and quickly dissolved in the water body;

[0032] In the above process, the rotation of the vibration unit 5 will make the spring 502 swing due to inertia and expand and contract due to the centrifugal force, and the continuous swing and expansion of the spring 502 can not only help break the bubbles to ensure the dissolution of oxygen in the water, but also the spring 502 can drive the connecting ring 503 to swing and move, so the connecting ring 503 will continuously hit the fixing rod 501 and the fixing plate 504, thereby causing the net drum 4 to vibrate, and the vibration of the net drum 4 can cause the vibration of the surrounding water, so as to disperse the cultured organisms and prevent them from excessively gathering around the net drum 4.

[0033] Example 2

[0034] See attached Figure 4 The present application provides an aerator for aquaculture. Compared with Example 1, in order to facilitate the maintenance of the device, an annular groove is provided on the outer side of the bottom end of the turntable 301, and a threaded through hole is provided on one side of the turntable 301 at the annular groove. The turntable 301 is threadedly connected with a bolt 7 at the threaded through hole. The net cylinder 4 is adapted to the annular groove, and the annular groove has the same diameter as the net cylinder 4. Therefore, the top of the net cylinder 4 can be inserted into the turntable 301 at the annular groove, and then the bolt 7 can be tightened to fix the net cylinder 4. Conversely, the net cylinder 4 can also be disassembled to facilitate cleaning thereof, thereby ensuring that the net cylinder 4 will not be excessively blocked and affect the aeration effect when the device is used for a long time.

[0035] Working principle: After the device has been used for a certain period of time, the net cylinder 4 can be disassembled after loosening the bolts 7. At this time, the net cylinder 4 can be easily cleaned to avoid clogging of the net cylinder 4 due to the underwater environment.
