Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an oxygen aeration device for aquaculture. Background Technology

[0002] Aquaculture refers to the cultivation of aquatic economic animals and plants by humans using available water bodies and employing aquaculture techniques and facilities, according to the different ecological habits and environmental requirements of the cultivated organisms. During the cultivation process, the large number of farmed organisms and various organic matter consume significant amounts of oxygen in the water, leading to hypoxia and causing disease or death in the farmed organisms. Therefore, current aquaculture requires aeration devices to regularly or irregularly aerate the water. However, existing equipment sometimes only aerates fixed areas or areas near the water surface, resulting in generally low aeration efficiency.

[0003] Existing technologies, such as Chinese Patent Publication No. CN215975197U, disclose an aeration device for aquaculture, including a hull with a bearing cavity inside. An air pump is fixedly installed inside the bearing cavity. A sleeve is fixedly connected to one side of the outer wall of the air pump, an injection pipe is fixedly connected to the top of the sleeve, a connecting pipe is fixedly connected to one side of the sleeve, and an air collection box is fixedly connected to one side of the connecting pipe. Through the designed exhaust box and air collection box, air is transported to the interior of the air collection box via the connecting pipe and then discharged from the exhaust box. Simultaneously, the intake port draws water into the air collection box, mixes it with the air drawn in by the connecting sleeve, and then discharges it from the exhaust box. This increases power, allowing the aeration device to operate in specific water areas and inject large amounts of oxygen into those areas, reducing energy consumption and improving overall efficiency. However, this invention cannot control or adjust the device's direction of movement in the water, and manual adjustment is required when operating in deeper waters, which is inconvenient. Frequent adjustments to the aeration depth become even more cumbersome.

[0004] To address the issues of insufficient mobility and applicability of aeration equipment, and to avoid situations where the equipment can only aerate in fixed areas or cannot aerate deeper waters, improvements are needed. Utility Model Content

The adjustment device is disposed on the surface of the air storage tank, and the adjustment device includes a screw threadedly connected to the inner surface of the air storage tank. A fixed platform is rotatably connected to the surface of the screw, and a motor is disposed inside the fixed platform. The motor is fixedly connected to the inner wall of the fixed platform, and a drive gear is fixedly connected to the output end of the motor.

[0007] Furthermore, the surface of the driving gear is meshed with a driven gear, the driven gear is fixedly connected to the surface of the screw, the surface of the fixed platform is fixedly connected with a connecting block, there are multiple sets of connecting blocks, the inner wall of the connecting block is fixedly connected with a cleaning brush, and the cleaning brush is slidably connected to the surface of the air guide tube.

[0008] Furthermore, the screw has a threaded connection to a movable block, which is fixedly connected to the surface of the gas storage tank. The movable block has a rotatable connection to a connecting rod, which consists of four sets. Each connecting rod has a float rotatably connected to its end away from the screw, and an air bladder is fixedly connected to its surface.

[0009] Furthermore, an anti-detachment disc is fixedly connected to one end of the screw near the movable block, a limit disc is fixedly connected to the surface of the screw, the limit disc is rotatably connected to the surface of the fixed platform, and the driven gear is rotatably connected to the surface of the fixed platform.

[0010] Furthermore, the surface of the connecting block is provided with a flow-pushing device, the flow-pushing device including a connecting platform, the connecting platform being fixedly connected to the surface of the connecting block, the surface of the connecting platform being fixedly connected with guide columns, the number of guide columns being two sets, the end of the guide column away from the connecting platform being fixedly connected with a limiting platform, the surface of the guide column being slidably connected with a movable platform, the number of movable platforms being two sets, the surface of the movable platform being fixedly connected with a flow-pushing column, the number of flow-pushing columns being multiple sets.

[0011] Furthermore, a rotating gear is rotatably connected to the surface of the fixed platform. There are two sets of rotating gears. The rotating gears mesh with the surfaces of the driven gears. A cylinder is fixedly connected to the surface of the rotating gear. A connecting rod is rotatably connected to the surface of the cylinder. The other end of the connecting rod is rotatably connected to a cylinder. The cylinder is fixedly connected to the surface of the movable platform.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an adjustment device, when aeration is required, the equipment is first placed in water. The equipment floats on the water surface by means of the air bladder on the float. The aeration pump is started using an external controller to draw external oxygen into the storage tank, then delivers it to the aeration head through the air guide pipe, and finally outputs it into the water. During this process, the external controller causes the motor to rotate, which drives the drive gear to rotate, which in turn drives the screw to rotate. This causes the storage tank, along with the aeration pump and air guide pipe, to slide up and down along the inner wall of the connecting block. By continuously rotating the motor in both directions, the air guide pipe and aeration head repeatedly move up and down, thus achieving aeration. The up-and-down movement of the aeration tube allows for uniform aeration of water at different depths. To prevent the equipment's center of gravity from shifting as the air duct descends into the water, the movable block on the screw moves downwards simultaneously. The connecting rod pushes the float and airbag outwards to adjust the center of gravity and prevent the equipment from tipping over. During this process, the cleaning brush on the connecting block cleans the aeration heads near the top of the air duct, preventing floating debris from clogging them. The adjustable device allows for uniform aeration of water at different depths by adjusting the height of the aeration heads, while simultaneously shifting the center of gravity to prevent tipping during adjustment. This effectively improves the equipment's versatility.

[0015] 2. In this utility model, by setting up a flow-pushing device and using an external controller to control motor two, motor two drives the connecting column to rotate, which in turn drives the active bevel gear to rotate, causing the driven bevel gear meshing with it to rotate, which in turn drives the rotating shaft to rotate, causing the propeller to rotate and thus moving the equipment. The four sets of motor two in different directions can cooperate with each other to control the precise movement of the equipment in the water. When motor one works and causes the driven gear to rotate, the two sets of rotating gears meshing with it will also rotate, which in turn drives cylinder one to rotate, causing the connecting rod to drive the two sets of movable platforms to reciprocate along the guide column. During this process, the flow-pushing column on the movable platform continuously pushes the water surface, increasing the aeration efficiency. The rotating blades connected to one end of the screw will also rotate with the rotation of the screw, thereby stirring the deep water. In conjunction with the operation of the aeration head, by setting up a flow-pushing device, the water surface and deep water are pushed and stirred, which facilitates the precise movement of the equipment while increasing the exchange of water and oxygen, and facilitates the operation of the aeration head to improve the aeration efficiency. This effectively improves the ease of use of the equipment. Attached Figure Description

Detailed Implementation

[0023] Please see Figure 1-5 This utility model provides a technical solution: an oxygen aeration device for aquaculture, including an aeration pump 1, an air storage tank 2, an air guide pipe 3, an aeration head 4, and an adjustment device 5. The air storage tank 2 is fixedly installed on the surface of the aeration pump 1, the air guide pipe 3 is fixedly installed on the surface of the air storage tank 2, the aeration head 4 is set on the surface of the air guide pipe 3, and there are multiple sets of aeration heads 4. The adjustment device 5 is set on the surface of the air storage tank 2.

[0024] The specific settings and functions of the regulating device 5 and the propulsion device 6 will be explained in detail below.

[0025] In this embodiment: the adjusting device 5 includes a screw 501, which is threadedly connected to the inner surface of the gas storage tank 2. A fixed platform 502 is rotatably connected to the surface of the screw 501. A motor 503 is installed inside the fixed platform 502. The motor 503 is fixedly connected to the inner wall of the fixed platform 502. A drive gear 504 is fixedly connected to the output end of the motor 503.

[0026] The effect achieved by the above components is that the starting motor 503 can drive the drive gear 504 to rotate. The motor is set in the fixed platform 502 to avoid direct contact with water.

[0027] Specifically, the driven gear 505 is meshed with the surface of the driving gear 504, the driven gear 505 is fixedly connected to the surface of the screw 501, the surface of the fixed platform 502 is fixedly connected to the connecting block 506, there are multiple sets of connecting blocks 506, the inner wall of the connecting block 506 is fixedly connected to the cleaning brush 507, and the cleaning brush 507 is slidably connected to the surface of the air guide tube 3.

[0028] The effects achieved by the above components are as follows: the rotation of the drive gear 504 drives the driven gear 505 to rotate, causing the screw 501 to rotate, which in turn causes the air tank 2, along with the aeration pump 1 and the air guide pipe 3, to move up and down on the screw 501. The motor 503 continuously rotates in both directions, causing the air guide pipe 3 and the aeration head 4 to move up and down repeatedly. This up-and-down movement can both turbulence the water flow and provide uniform aeration to water at different depths. During this process, the cleaning brush 507 on the connecting block 506 cleans the aeration heads 4 near the top of the air guide pipe 3 to prevent floating debris from clogging the aeration heads 4. The connecting block 506 also prevents the air tank 2 from rotating along with the air guide pipe 3.

[0029] Specifically, the surface of the screw 501 is threaded with a movable block 508, which is fixedly connected to the surface of the gas tank 2. The surface of the movable block 508 is rotatably connected with a connecting rod 509. There are four sets of connecting rods 509. The end of each connecting rod 509 away from the screw 501 is rotatably connected with a float 510. The surface of the float 510 is fixedly connected with an air bag 511.

[0030] The effect achieved by the above components is as follows: when the screw 501 rotates, the movable block 508 moves up and down synchronously with the air tank 2. When the air pipe 3 descends into the water, it will cause the center of gravity of the equipment to change. At this time, the movable block 508 moves down synchronously, and the connecting rod 509 pushes the float 510 and the air bag 511 to the sides to adjust the center of gravity and prevent the equipment from tipping over. When the air pipe 3 moves up, the movable block 508 will also move up synchronously, so that the connecting rod 509 drives the float 510 and the air bag 511 to retract. The movable block 508 and the air tank 2 are fixedly connected to prevent the movable block 508 from rotating.

[0031] Specifically, an anti-detachment disc 512 is fixedly connected to one end of the screw 501 near the movable block 508, a limit disc 513 is fixedly connected to the surface of the screw 501, the limit disc 513 is rotatably connected to the surface of the fixed platform 502, and the driven gear 505 is rotatably connected to the surface of the fixed platform 502.

[0032] The effects achieved by the above components are as follows: the anti-detachment disc 512 is set to prevent the movable block 508 and the air tank 2 from detaching from the screw 501; the limit disc 513 and the driven gear 505 abut against the two side surfaces of the fixed platform 502 to prevent the screw 501 from moving up and down.

[0033] Specifically, the surface of the connecting block 506 is provided with a flow-pushing device 6, which includes a connecting platform 601. The connecting platform 601 is fixedly connected to the surface of the connecting block 506. The surface of the connecting platform 601 is fixedly connected with guide posts 602. There are two sets of guide posts 602. The end of the guide post 602 away from the connecting platform 601 is fixedly connected with a limiting platform 603. The surface of the guide post 602 is slidably connected with a movable platform 604. There are two sets of movable platforms 604. The surface of the movable platform 604 is fixedly connected with a flow-pushing column 605. There are multiple sets of flow-pushing columns 605.

[0034] The effects achieved by the above components are as follows: the propulsion column 605 is set to propel the water surface and increase the oxygen exchange efficiency; the guide column 602 is set to provide guidance for the movement of the movable platform 604.

[0035] Specifically, a rotating gear 606 is rotatably connected to the surface of the fixed platform 502. There are two sets of rotating gears 606. The rotating gears 606 mesh with the surface of the driven gear 505. A cylinder 607 is fixedly connected to the surface of the rotating gear 606. A connecting rod 608 is rotatably connected to the surface of the cylinder 607. A cylinder 609 is rotatably connected to the other end of the connecting rod 608. The cylinder 609 is fixedly connected to the surface of the movable platform 604. A rotating blade 610 is fixedly connected to the end of the screw 501 away from the movable block 508.

[0036] The effects achieved by the above components are as follows: when the motor 503 causes the driven gear 505 to rotate, the rotating gear 606 meshing with it will also rotate, thereby driving the cylinder 607 to rotate, causing the connecting rod 608 to drive the two sets of semi-circular movable platforms 604 to move back and forth along the guide column 602, so that the push column 605 pushes the water surface, and when the screw 501 rotates, it will also drive the rotating blade 610 at one end to rotate, stirring the deep water area, which is in conjunction with the operation of the aeration head 4.

[0037] Specifically, a second motor 611 is fixedly connected to the surface of the float 510, a connecting post 612 is fixedly connected to the output end of the second motor 611, a driving bevel gear 613 is fixedly connected to the surface of the connecting post 612, a driven bevel gear 614 is meshed with the surface of the driving bevel gear 613, a rotating shaft 615 is fixedly connected to the surface of the driven bevel gear 614, a propeller 616 is fixedly connected to one end of the rotating shaft 615, and the other end of the rotating shaft 615 is rotatably connected to the surface of the float 510.

[0038] The effect achieved by the above components is as follows: starting motor 611 causes connecting column 612 to rotate, which drives active bevel gear 613 to rotate, which in turn drives driven bevel gear 614 to rotate, which drives rotating shaft 615 to rotate, which in turn drives propeller 616 to rotate, so as to propel the equipment to move in the water. Four sets of propellers 616 are set to facilitate precise adjustment of the equipment's movement path.

[0039] Working Principle: By setting the adjustment device 5, when aeration is required, the equipment is first placed in water. The equipment floats on the water surface using the air bladder 511 on the float 510. The aeration pump 1 is started using an external controller to draw external oxygen into the air storage tank 2, which is then transported to the aeration head 4 through the air guide pipe 3 and finally output into the water. During this process, the external controller causes the motor 503 to rotate, which drives the drive gear 504 to rotate, causing the driven gear 505 to rotate, which in turn drives the screw 501 to rotate. This causes the air storage tank 2, along with the aeration pump 1 and the air guide pipe 3, to slide up and down along the inner wall of the connecting block 506. The motor 503 continuously rotates in both directions. This causes the air guide pipe 3 and aeration heads 4 to move up and down repeatedly, which not only disturbs the flow through the up-and-down movement but also provides uniform aeration to water at different depths. To prevent the equipment's center of gravity from shifting as the air guide pipe 3 descends deeper into the water, the movable block 508 on the screw 501 moves downwards simultaneously. The connecting rod 509 then pushes the float 510 and airbag 511 outwards to adjust the center of gravity and prevent the equipment from tipping over. During this process, the cleaning brush 507 on the connecting block 506 cleans the aeration heads 4 near the top of the air guide pipe 3 to prevent floating debris from clogging them. By setting up the adjustment device 5, the height of the aeration heads 4 can be adjusted to provide uniform aeration to water at different depths, and simultaneously... By shifting the center of gravity, the equipment is prevented from tipping over during adjustment, effectively improving its applicability. Furthermore, a propulsion device 6 is installed, and an external controller controls motor 611. Motor 611 drives the connecting column 612 to rotate, which in turn drives the driving bevel gear 613, causing the driven bevel gear 614 to rotate. This, in turn, drives the rotating shaft 615, causing the propeller 616 to rotate, thus moving the equipment. The four sets of motors 611 operating in different directions can cooperate to control the precise movement of the equipment in the water. Additionally, when motor 503 operates, causing the driven gear 505 to rotate, the two sets of rotating gears 606 meshing with it will also rotate accordingly. This causes the cylinder 607 to rotate, which in turn causes the connecting rod 608 to drive the two sets of movable platforms 604 to reciprocate along the guide column 602. During this process, the pusher column 605 on the movable platform 604 continuously pushes the water surface, increasing the aeration efficiency. The rotating blade 610 connected to one end of the screw 501 also rotates with the rotation of the screw 501, thereby stirring the deep water. In conjunction with the operation of the aeration head 4, by setting the pusher device 6, the water surface and deep water are pushed and stirred, which facilitates the precise movement of the equipment and accelerates the exchange of water and oxygen. This facilitates the operation of the aeration head 4 and improves the aeration efficiency, thus effectively improving the ease of use of the equipment.
