Description

Technical Field

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

[0002] In modern aquaculture, maintaining suitable dissolved oxygen levels in the water is crucial for the healthy growth of aquatic organisms such as fish and shrimp. Currently, agitated aeration devices are widely used in aquaculture ponds because they mechanically stir the water, increasing the contact area between water and air and promoting oxygen dissolution. However, the fixed-position agitation of existing aeration devices makes it difficult to achieve comprehensive oxygenation of the entire pond. Due to the limited aeration range, uneven dissolved oxygen levels easily form in the pond, with areas far from the agitation area having low dissolved oxygen levels that cannot meet the growth needs of aquatic organisms and may even lead to localized hypoxia, affecting the survival rate and growth rate of farmed organisms. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that due to the limited oxygenation range, the dissolved oxygen in the aquaculture pond is easily uneven. The dissolved oxygen in the area far away from the stirring and oxygenation is low, which cannot meet the growth needs of aquatic organisms and may even lead to local hypoxia, affecting the survival rate and growth rate of aquatic organisms. Therefore, we propose an aquaculture pond oxygenation device.

[0004] To achieve the above objectives, this application adopts the following technical solution: an aeration device for aquaculture ponds, comprising a main body of the aquaculture pond and an inlet located on one side of the main body of the aquaculture pond. An aeration regulating component is provided on the inner wall of the main body of the aquaculture pond. The aeration regulating component includes a first toothed rod and a second toothed rod that are slidably connected to the inner wall of the main body of the aquaculture pond. A drive gear is provided between the first toothed rod and the second toothed rod. An electric motor is fixedly connected to one end of the drive gear. The first toothed rod and the second toothed rod are symmetrically distributed about the center of the drive gear. A crossbar is fixedly connected to the end of the first toothed rod and the second toothed rod away from the inner wall of the main body of the aquaculture pond. A servo motor is fixedly connected to the outer wall of the crossbar. An aeration stirring body is fixedly connected to the output end of the servo motor.

[0005] Furthermore, the transverse connecting rod is provided in two sets, and both sets of the transverse connecting rod are symmetrically distributed about the center of the driving gear.

[0006] Furthermore, the driving gear has teeth on only half a circle of its outer wall, and the driving gear is meshed with the first rack and the second rack.

[0007] Furthermore, when the drive gear meshes with and continuously rotates with the first rack, the first rack and the second rack drive the crossbar and the oxygenation and stirring body to move to the left.

[0008] Furthermore, when the drive gear meshes with the second rack and rotates continuously, the first rack and the second rack drive the crossbar and the oxygenation and stirring body to move to the right.

[0009] Furthermore, a slider body is fixedly connected to the inner wall of the aquaculture pool body, and a groove body is provided at one end of the first toothed rod near the inner wall of the aquaculture pool body, and the slider body is slidably connected to the inner wall of the groove body.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] In this invention, as the drive gear rotates, its teeth continuously mesh with the first rack. According to the gear transmission principle, the rotational force of the drive gear is converted into a leftward thrust on the first rack, causing the first rack to begin to translate to the left. The horizontal connecting rod fixed at the end of the first and second racks away from the pool wall also moves synchronously, thereby driving the servo motor and the aeration and stirring body mounted on the horizontal connecting rod to translate to the left as a whole. When the drive gear rotates to the toothless region, it disengages from the first rack. At this time, the first and second racks stop moving in the current direction, but the motor continues to run, and the drive gear continues to move. The gear rotates until its meshing part engages with the second gear. At this point, the rotational force of the drive gear pushes the second gear to move to the left, causing the aeration and stirring body to start moving in the opposite direction. This cycle repeats, and the intermittent meshing transmission of the drive gear enables the aeration and stirring body to move horizontally along the pond wall within the aquaculture pond, continuously expanding the aeration coverage area. This solves the problem of limited aeration range and uneven dissolved oxygen in the aquaculture pond, where the dissolved oxygen level is low in areas far from the aeration and stirring area, failing to meet the growth needs of aquatic organisms and potentially leading to localized hypoxia, thus affecting the survival rate and growth rate of aquatic organisms.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] Reference Figures 1-4 As shown, in order to solve the problem of uneven dissolved oxygen in aquaculture ponds due to limited oxygenation range, and the low dissolved oxygen levels in areas far from aeration and stirring, which cannot meet the growth needs of aquatic organisms and may even lead to local hypoxia, affecting the survival rate and growth rate of aquatic organisms, the following preferred technical solutions are provided:

[0020] An aeration device for aquaculture ponds includes a core structure comprising a pond body 1, an inlet 2, and an innovative aeration regulating component 3. The inlet 2 is located on one side of the pond body 1 for water renewal. The aeration regulating component 3, as the core component, achieves dynamic aeration through a precise mechanical transmission design. The aeration regulating component 3 consists of a first toothed rod 31, a second toothed rod 32, a drive gear 33, a crossbar 34, a servo motor 35, and an aeration stirring body 36. The first toothed rod 31 and the second toothed rod 32 are horizontally arranged along the inner wall of the pond body 1, and form a sliding pair with a sliding groove body 5 formed on the toothed rod via a slider body 4, ensuring stable translation of the first toothed rod 31 and the second toothed rod 32 along the pond wall. The drive gear 33 is located between the first toothed rod 31 and the second toothed rod 32, and its unique design… The design features teeth on the outer half of the ring, which mesh with the first toothed rod 31 and the second toothed rod 32 respectively. The drive gear 33 is driven by an electric motor. When the motor drives the drive gear 33 to rotate clockwise, its toothed part first meshes with the first toothed rod 31. Through the gear transmission principle, it pushes the first toothed rod 31 to move to the left, thereby driving the transverse connecting rod 34 fixed at the ends of the first toothed rod 31 and the second toothed rod 32 and the aeration mixing body 36 to move to the left as a whole. When the drive gear 33 rotates to the toothless area and disengages from the first toothed rod 31, it continues to rotate until the toothed part meshes with the second toothed rod 32. Then, it pushes the second toothed rod 32 to move to the left in the opposite direction, realizing the reverse translation of the aeration mixing body 36. This reciprocating horizontal movement mechanism allows the aeration mixing body 36 to cover a larger area of ​​water.

[0021] Two sets of horizontal connecting rods 34 are arranged in a centrally symmetrical manner to ensure the balance of the aeration mixing body 36 during translation. The servo motor 35 installed on the horizontal connecting rods 34 can independently control the rotation speed and angle of the aeration mixing body 36. Through mechanical stirring, water flow disturbance is generated, increasing the contact area between the water and air and promoting oxygen dissolution. At the same time, the translational movement of the aeration mixing body 36, combined with its own rotation, can break the dissolved oxygen stratification phenomenon in the aquaculture pond, so that the oxygen-rich surface water and the bottom water are fully mixed.

[0022] Specifically, firstly, the motor connected to one end of the drive gear 33 is energized and operates, serving as the power source for the entire device. The motor outputs stable rotational power, driving the drive gear 33 to begin rotating clockwise. At this time, the half-turn of the drive gear 33 with meshing teeth begins to mesh with the first rack 31, laying the foundation for subsequent motion transmission. Simultaneously, the first rack 31 and the second rack 32 are tightly fitted against the inner wall of the aquaculture tank body 1 through the sliding pair structure of the slider body 4 and the chute body 5. This sliding pair not only restricts the direction of movement of the racks, allowing them to only move horizontally, but also provides support and stability, ensuring that the racks do not sway or deviate when subjected to force. As the drive gear 33 rotates, its teeth continuously mesh with the first rack 31, according to the gear transmission... The principle is that the rotational force of the drive gear 33 is converted into a leftward thrust of the first rack 31, causing the first rack 31 to begin to translate to the left. The horizontal connecting rod 34, which is fixed to the end of the first rack 31 and the second rack 32 away from the pool wall, also moves synchronously, thereby driving the servo motor 35 and the aeration and stirring body 36 mounted on the horizontal connecting rod 34 to translate to the left as a whole. When the drive gear 33 rotates to the toothless area, it disengages from the first rack 31. At this time, the first rack 31 and the second rack 32 stop moving in the current direction, but the motor continues to run, and the drive gear 33 continues to rotate until its meshing part meshes with the second rack 32. At this time, the rotational force of the drive gear 33 pushes the second rack 32 to translate to the left, causing the aeration and stirring body 36 to begin to move in the opposite direction. In this cycle, the intermittent meshing transmission of the drive gear 33 enables the aeration and stirring body 36 to move horizontally along the pond wall within the main body 1 of the aquaculture pond, continuously expanding the aeration coverage area. This solves the problem of limited aeration range and uneven dissolved oxygen in the aquaculture pond, where the dissolved oxygen level is low in areas far from the aeration and stirring area, which cannot meet the growth needs of aquatic organisms and may even lead to local hypoxia, affecting the survival rate and growth rate of aquatic organisms.

[0023] While the aeration mixing body 36 is performing horizontal reciprocating motion, the servo motor 35 on the crossbar 34 starts to work. The servo motor 35 can precisely control the rotation speed and angle of the aeration mixing body 36 according to actual needs. The blades of the aeration mixing body 36 rotate at high speed under the drive of the servo motor 35, stirring the surrounding water. According to the principles of fluid mechanics, the rotating blades will cause eddies and turbulence in the water. On the one hand, this greatly increases the contact area between the water and the air, creating favorable conditions for oxygen dissolution. On the other hand, the strong water flow disturbance can break the static stratification of the water and promote the mixing of water at different depths.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
