Description

Technical Field

[0001] This utility model belongs to the technical field of fishpond aeration devices, and particularly relates to an adjustable-depth fishpond aeration device. Background Technology

[0002] An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency. It can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the fish's living environment. Aerators generally rely on their built-in air pumps to inject air into the water, thereby increasing the oxygen content in the water.

[0003] For example, Chinese patent document (CN212589694U) discloses a water turbine-type fishpond aerator, which includes a support platform. Evenly distributed connecting rods are fixedly installed around the perimeter of the support platform, and a float is fixedly installed at one end of each connecting rod. A drive motor is fixedly installed on the top of the support platform. In this water turbine-type fishpond aerator, rotating the locking screw releases the restriction on the position of the adjusting rod, pulling the adjusting rod moves the connecting plate, the third drive rod, and the drive turbine, adjusting the working depth of the drive turbine. This allows the device to aerate deeper water, improving the aeration effect. Furthermore, the third drive rod is movably connected to the connecting plate via a limit bearing, ensuring that the third drive rod can rotate freely while the connecting plate can move the third drive rod up and down to adjust the working depth of the drive turbine.

[0046] 1. In this utility model, through the set extraction and cleaning components, the water pump extracts water from fishponds at different depths through the inlet pipe and filter frame, and discharges it through the outlet pipe, connecting box, and multiple drain pipes. During this process, the discharged water fully contacts the air, effectively increasing the dissolved oxygen content of the water and thus enhancing the oxygen content inside the fishpond. At the same time, the water inside the connecting box drives the inclined blades, rotating shaft, arc block, mounting sleeve, and cleaning brush to rotate. The cleaning brush cleans the outer periphery of the filter frame to prevent blockage during long-term use, ensuring stable and efficient water pumping and oxygenation processes. This significantly improves the continuous working capacity of the equipment, guarantees the oxygenation effect of the fishpond, and reduces the maintenance frequency and operating costs of the device during use.

[0047] 2. In this utility model, the oxygen supply adjustment component causes the winding wheel, connecting shaft, and lead screw to rotate during the downward movement of the fixed seat. This causes the lead screw seat to move the limiting rod, and under the action of the stroke groove, the first circular plate rotates inside the fixed seat. At this time, the positions of the first and second through holes change, that is, the interaction area between the first and second through holes is reduced. During the oxygen supply process of the external oxygen supply device and pipeline oxygen supply, the diameter of the oxygen-containing bubbles output by the first through hole is reduced to help increase the dissolution effect of oxygen-containing bubbles with water. The device reduces the output diameter of the first through hole according to different depths. Under constant air supply pressure, the reduction of the orifice significantly increases the fluid shear force when oxygen overflows, thereby breaking the oxygen into finer micro-nano bubbles, making it suitable for oxygen dissolution effects at different depths.

[0064] One end of the liquid inlet pipe 404 is connected to the input end of the water pump 403;

[0065] The filter frame 405 is fixedly connected to the bottom of the fixed base 3, and the top of the filter frame 405 is connected to the bottom end of the liquid inlet pipe 404.

[0066] The rotating shaft 406 is rotatably connected inside the filter frame 405, and the cross-sectional shape of the filter frame 405 is set to be annular.

[0067] The mounting sleeve is fixedly connected to the bottom end of the rotating shaft 406, and cleaning brushes 407 are fixedly connected to both sides of the mounting sleeve.

[0068] Two arc-shaped blocks 408 are fixedly connected to the outer periphery of the rotating shaft 406 on opposite sides, and connecting sleeves are fitted on the outer periphery of the arc-shaped blocks 408 and the rotating shaft 406. The connecting sleeves are rotatably connected inside the connecting box 402, and the arc-shaped blocks 408 and the rotating shaft 406 are slidably connected inside the protective box 401.

[0072] The liquid inlet pipe 404 is a flexible hose, and the liquid inlet pipe 404 is located inside the adjusting hollow rod 2.

[0073] Detailed Implementation: First, two external linear modules are symmetrically installed on the top of the mounting base 1, and their bottoms are fixedly connected to the top of the fixed base 3. Then, external buoys are installed on the outer periphery of the mounting base 1, allowing the device to float on the surface of the fishpond. The external linear modules will fix the position of the fixed base 3 relative to the mounting base 1. The water pump 403 is then started as needed. The water pump 403 draws water from different depths of the fishpond through the inlet pipe 404 and the filter frame 405, and delivers it to the connecting box 402 through the outlet pipe. At this time, the liquid inside the connecting box 402 is discharged through multiple drain pipes 410. During this process, the discharged water is mixed with air. The system achieves effective contact and increases dissolved oxygen levels in the water, thereby enhancing the oxygen content within the fishpond. During this process, the water source inside the connecting box 402 drives the inclined blades 409 to rotate. Utilizing the linkage effect between the inclined blades 409, the rotating shaft 406, and the arc-shaped block 408, the rotating shaft 406 drives the mounting sleeve and cleaning brush 407 to rotate. The cleaning brush 407 cleans the outer periphery of the filter frame 405 to prevent clogging during prolonged use, ensuring stable and efficient water pumping and oxygenation processes. This significantly improves the continuous working capacity of the equipment, guarantees the oxygenation effect of the fishpond, and reduces the maintenance frequency and operating costs during use.

[0074] Oxygen supply regulating component 5 includes:

[0075] The connecting shaft 501 is rotatably connected inside the fixed base 3;

[0076] The winding wheel 502 is sleeved on the outer periphery of the connecting shaft 501, and the winding wheel 502 is fixedly connected to the fixing block 511 by the wire rope. The fixing block 511 is fixedly connected to the top outer periphery of the adjusting hollow rod 2.

[0077] A torsion spring 503 is sleeved on the outer periphery of the connecting shaft 501, and the torsion spring 503 is fixedly connected inside the fixed base 3;

[0078] The lead screw 504 is rotatably connected inside the fixed base 3, and one end of the lead screw 504 is fixedly connected to the connecting shaft 501;

[0079] The lead screw seat 505 is connected to the outer periphery of the lead screw 504 for transmission.

[0080] The first circular plate 506 is disposed above the lead screw seat 505 and is rotatably connected to the inside of the fixed seat 3. The first circular plate 506 has multiple second through holes 509 arranged in a circular array inside.

[0081] The second circular plate 507 is fixed inside the fixing base 3, and the second circular plate 507 is located on top of the first circular plate 506. Multiple first through holes 508 are distributed in a circular array inside the second circular plate 507.

[0082] The stroke groove 510 is located on one side of the bottom of the first circular plate 506, and the stroke groove 510 is set in an oblique shape;

[0083] The limit rod is slidably connected inside the stroke groove 510, and the bottom end of the limit rod is fixedly connected to the top of the lead screw seat 505.

[0084] Detailed Implementation: During the downward movement of the fixed base 3, the fixed block 511 and the wire rope drive the winding wheel 502, connecting shaft 501, and lead screw 504 to rotate. Utilizing the linkage effect between the lead screw 504 and the lead screw seat 505, power is transmitted to the lead screw seat 505, causing the lead screw seat 505 to drive the limiting rod to move. Under the action of the limiting rod and the stroke groove 510, the first circular plate 506 rotates inside the fixed base 3. At this time, the positions of the first through hole 508 and the second through hole 509 change. That is, the interaction area between the first through hole 508 and the second through hole 509 will be reduced. During the process of external oxygen supply device and pipeline oxygen supply, the diameter of the bubble with oxygen content output by the first through hole 508 will be reduced to help increase the dissolution effect of oxygen-containing bubbles with water source. The device reduces the output orifice diameter of the first through hole 508 according to different depths. Under constant air supply pressure, the reduction of the orifice significantly increases the fluid shear force when oxygen overflows, thereby breaking the oxygen into finer micro-nano bubbles, so that it is suitable for oxygen dissolution effect at different depths.

[0085] Working principle: In use, first, symmetrically install the two external linear modules on the top of the mounting base 1, and fix their bottoms to the top of the fixed base 3. Then, install the external buoy on the outer periphery of the mounting base 1. The external buoy makes the device float on the surface of the fishpond water. The external linear modules will fix the position of the fixed base 3 relative to the mounting base 1. Start the water pump 403 as needed. The water pump 403 will draw water from the fishpond at different depths through the inlet pipe 404 and the filter frame 405, and deliver the water through the outlet pipe. The liquid is sent into the connecting box 402. At this time, the liquid inside the connecting box 402 will be discharged through multiple drain pipes 410 and come into contact with oxygen in the air to increase the oxygen content of the water in the fishpond. During this process, the water inside the connecting box 402 will drive the inclined blades 409 to rotate. Utilizing the linkage effect between the inclined blades 409, the rotating shaft 406 and the arc block 408, the rotating shaft 406 drives the mounting sleeve and cleaning brush 407 to rotate. The cleaning brush 407 cleans the outer periphery of the filter frame 405.

[0086] As the fixed seat 3 moves downward, the fixed block 511 and the wire rope drive the winding wheel 502, the connecting shaft 501, and the lead screw 504 to rotate. Utilizing the linkage effect between the lead screw 504 and the lead screw seat 505, the power is transmitted to the lead screw seat 505, causing the lead screw seat 505 to drive the limit rod to move. Under the action of the limit rod and the stroke groove 510, the first circular plate 506 rotates inside the fixed seat 3. At this time, the positions of the first through hole 508 and the second through hole 509 change, that is, the interaction area between the first through hole 508 and the second through hole 509 is reduced. During the process of external oxygen supply device and pipeline oxygen supply, the diameter of the bubble with oxygen content output from the first through hole 508 is reduced.

[0087] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
