Description

Technical Field

[0001] This invention belongs to the field of fish fry breeding technology, specifically a fish fry breeding pond for different fish fry breeding and its adjustment method. Background Technology

[0002] Fish fry breeding ponds are specific pools used to breed fish fry. The shape of the pond is mostly rectangular, round or oval, and the specific shape is determined according to the terrain and breeding needs. The size is designed according to the scale of breeding and the number of fish fry to ensure that the fish fry have enough space to grow and move around. The pond material is often made of durable and easy-to-clean materials such as concrete, fiberglass, PVC or PP.

[0003] In existing fish fry breeding ponds, oxygenation is typically required to maintain suitable oxygen levels and improve egg development. However, different fish species require different optimal oxygen concentrations for breeding, and the oxygen consumption levels of different fry also vary. Therefore, the actual oxygenation requirements within the breeding pond differ. Current oxygenation methods are fixed and can only be controlled by starting and stopping, making it difficult to effectively control the amount and rate of oxygenation within the pond. This generally results in poor breeding outcomes for different fry species. Furthermore, for some fry that require suspended spawning, there is a lack of effective ways for the eggs to attach in the pond. Even when using a large amount of aquatic plants, the density reduces the available space near the eggs, lowering the oxygen concentration and failing to maintain optimal conditions for breeding, leading to unsatisfactory results. Summary of the Invention

[0012] Preferably, the pushing assembly includes a toothed plate and an electric push rod. The toothed plate is meshed with a gear, and the electric push rod is fixed to the side of the pool body via a bottom frame. The movable end of the electric push rod is fixedly connected to the toothed plate and pushes the toothed plate to reciprocate.

[0013] Preferably, the power unit includes a servo motor and a third gear. The servo motor drives the third gear to rotate, and the third gear meshes with the first gear.

[0014] Preferably, the dispensing assembly includes a dispensing frame, a sleeve, and a connecting rod. The two ends of the dispensing frame are fixedly connected to the connecting rod and to the pool body via the connecting rod. The sleeve is fixedly connected to the front of the dispensing frame and communicates with the interior of the dispensing frame. The other end of the sleeve is movably sleeved on the outer end of the tube body. A sealing ring is nested in the inner wall of the sleeve and sleeved on the outer side of the tube body.

[0015] Preferably, a rotary filter section is fixedly sleeved on the outer surface of one of the oxygenation cylinder assemblies.

The liquid inlet end of the discharge pipe is located on the rotation path of the guide frame.

[0016] A method for adjusting fish fry breeding ponds used for different fish fry breeding, comprising the following adjustment steps:

[0017] Step 1: When it is necessary to adapt to the breeding of different types of fish fry, the push component is activated according to the oxygen supply requirements of different types of fish fry. The push component drives the adjustment component to rotate, so that the position of the arc-shaped trough and the arc-shaped opening changes and gradually overlaps, thus increasing the oxygen supply. When it is necessary to reduce the oxygen supply, the position of the arc-shaped trough and the arc-shaped opening changes and gradually moves away, thus reducing the amount of oxygen input into the pond through the arc-shaped opening.

[0018] Step 2: When some fish eggs need to be suspended in the pool, start the power unit to rotate the aeration cylinder assembly, keep a set of simulated components in the front, and at the same time, the simulated components on both sides are suspended on both sides under the buoyancy. This type of fish will attach the fish eggs to the flexible floating belt.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention utilizes a rotatable adjustment component connected to a rotatable adjustable aeration cylinder component. The rotation of the adjustment component, in conjunction with the aeration cylinder component, controls the actual air outlet size, thereby changing the oxygen input rate under a fixed quantity and rate of oxygen input. This allows for the regulation and control of oxygen content in the breeding pond, adapting to the breeding standards of different fish fry, optimizing breeding quality. Furthermore, the simulated component on the aeration cylinder component mimics the effect of aquatic plants, enabling the attachment of fish eggs suspended in the water, providing stable attachment for suspended spawning fry eggs. Simultaneously, the corresponding aeration outlets arranged near the simulated component simulate the effect of aquatic plants attaching fish eggs while avoiding the space-consuming effect of large amounts of aquatic plants that would reduce the nearby oxygen concentration. This invention adapts to the breeding of different fish fry while further improving breeding efficiency, optimizing the developmental environmental parameters of breeding fish eggs, and enhancing breeding results.

[0021] 2. This invention reuses the rotating aerator assembly and the rotatable adjustment component. When it is necessary to clean the sediment inside the tank, the air outlet direction of the aerator assembly is changed, and the adjustment component is rotated accordingly to ensure that the supplied oxygen is directed towards the dirt at the bottom of the water body, disturbing the bottom sediment and making the sediment evenly dispersed in the water body. At the same time, the rotating filter part that rotates with the aerator assembly ensures that the filtration treatment at the discharge pipe is released at this time, so that the disturbed suspended sediment can be quickly discharged through the opened discharge pipe, providing an internal cleaning effect.

[0022] 3. This invention utilizes the rotating filter section that follows the rotation of the aerator assembly, along with a cleaning rod added to the tank. By positioning the cleaning rod on the front of the rotating filter section, the relative friction between the rotating filter section and the cleaning rod is simultaneously achieved during the rotation control of the aerator assembly, thereby synchronously completing the unclogging operation of the arc-shaped filter tank. The actual unclogging operation is simple, requiring no additional unclogging steps or equipment, and can easily and synchronously complete the self-unclogging operation, resulting in good performance.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 9As shown, this embodiment of the invention provides a fish fry breeding pond for different fish fry breeding and its adjustment method, including a pond body 1. An aerator assembly 4 is rotatably fitted inside the pond body 1. A simulation component 5 is fixed on the outer surface of the aerator assembly 4. An adjustment component 6 is rotatably fitted inside the aerator assembly 4. A pushing component 7 is fixedly provided on one side of the pond body 1, which pushes the adjustment component 6 to rotate. A distribution component 8 is fixedly provided on the other side of the pond body 1. One end of the distribution component 8 is connected to the adjustment component 6. An oxygen supply mechanism is externally connected to the air inlet end of the distribution component 8.

[0035] The oxygenation cylinder assembly 4 includes a cylinder body 41, a gear 42, and an arc-shaped inlet 43.

[0036] The adjustment component 6 includes a tube body 61, an arc groove 62, a gear 63, an annular groove 64, and an internal cavity 65.

[0037] Example 1: When it is necessary to adapt to the breeding of different types of fish fry, according to the oxygen supply requirements of different types of fish fry, the push assembly 7 is activated. The electric push rod 72 drives the toothed plate 71 to move laterally, so that the toothed plate 71 in the push assembly 7 drives the gear 63 in the adjustment assembly 6 to rotate, so that the tube body 61 rotates, so that the arc-shaped groove 62 rotates in the cylinder 41 in the aeration cylinder assembly 4, so that the position of the arc-shaped groove 62 and the arc-shaped opening 43 changes and gradually coincides, and the opening size of the arc-shaped groove 62 increases. The external oxygen supply mechanism inputs oxygen into the distribution assembly 8. The oxygen is input into each group of tube bodies 61 through the distribution frame 81 and the sleeve 82, and is input into the pond water through the internal cavity 65, the arc-shaped groove 62 and the arc-shaped opening 43, expanding the oxygen supply. When the fish need to adapt to low-oxygen breeding conditions, the oxygenation rate needs to be reduced. This causes the positions of the arc-shaped trough 62 and the arc-shaped opening 43 to change and gradually move away from each other, reducing the amount of oxygen input into the pond 1 through the arc-shaped opening 43. When some fish eggs need to be suspended in the pond 1 for breeding, the power unit 9 is activated, which drives the gear 42 in the aeration cylinder assembly 4 to rotate, thereby rotating the cylinder 41. The rotation of the aeration cylinder assembly 4 keeps a set of simulated components 5 fixed on the same cylinder 41 in a positive position, while the simulated components 5 on both sides are suspended on both sides under the action of buoyancy. Each set of simulated components 5 is fully arrayed and suspended in the pond water. The fish eggs adhere to the flexible floating belt 53, completing stable suspension breeding.

[0038] First, by connecting the rotatable adjustment component 6 to the rotatable adjustable aeration cylinder component 4, the rotation of the adjustment component 6, in conjunction with the aeration cylinder component 4, controls the actual air outlet size. This allows for changes in the oxygen input rate under a fixed quantity and rate of oxygen input, thereby regulating and controlling the oxygen content in the breeding pond. This adapts to the breeding standards of different fish fry, optimizes breeding quality, and, in conjunction with the simulation component 5 on the aeration cylinder component 4, simulates the effect of aquatic plants, enabling the attachment of fish eggs suspended in the water. This provides stable attachment for fish eggs from suspended spawning fry. Simultaneously, the corresponding aeration outlets arranged near the simulation component 5 simulate the effect of aquatic plants attaching fish eggs while avoiding the space-consuming effect of large amounts of aquatic plants that would reduce the nearby oxygen concentration. This adapts to the breeding of different fish fry while further improving breeding efficiency, optimizing the developmental environmental parameters of the breeding fish eggs, and enhancing the breeding effect.

[0039] Example 2: When it is necessary to clean the sediment inside the tank 1, the power unit 9 is restarted to drive the aerator assembly 4 to rotate, keeping the set of arc-shaped openings 43 facing the bottom of the tank 1, and driving the rotating filter 10 to rotate, so that the guide frame 102 and the discharge pipe 3 are misaligned, canceling the filtration process. The push assembly 7 is started and the adjustment assembly 6 is driven to rotate, maintaining the alignment and full opening of the arc-shaped openings 43 and the arc-shaped grooves 62, maintaining oxygen input, and the oxygen is given to vertically blow the bottom of the tank 1, causing the sediment at the bottom of the tank to surge. The discharge pipe 3 is opened to realize the flow and discharge of sediment after the start-up disturbance. When the flowing water is changed during normal breeding, the rotating filter 10 on the set of aerator assembly 4 is aligned with the discharge pipe 3. When the discharge pipe 3 is opened, only the filtered water is released, and the fish fry are kept in the tank water. During the rotation process, the front of the rotating filter 10 rubs against the cleaning rod 11 to complete the automatic unblocking.

[0040] First, by reusing the rotating aerator assembly 4 and the rotatable adjustment assembly 6, when it is necessary to clean the sediment inside the tank 1, the air outlet direction of the aerator assembly 4 is changed, and the adjustment assembly 6 is rotated accordingly to ensure that the supplied oxygen is directed towards the dirt at the bottom of the water body, disturbing the bottom sediment and making the sediment evenly dispersed in the water body. At the same time, the rotating filter 10, which rotates with the aerator assembly 4, ensures that the filtration treatment at the discharge pipe 3 is released at this time, so that the disturbed suspended sediment can be quickly discharged through the opening of the discharge pipe 3, providing an internal cleaning effect.

[0041] Furthermore, by utilizing the rotating filter section 11 that follows the rotation of the aerator assembly 4, in conjunction with the cleaning rod 11 added to the tank body 1, and by positioning the cleaning rod 11 on the front of the rotating filter section 10, the relative friction between the rotating filter section 10 and the cleaning rod 11 is simultaneously achieved during the rotation control of the aerator assembly 4, thereby simultaneously completing the unclogging operation of the arc-shaped filter tank 103. The actual unclogging operation is simple, requiring no additional unclogging steps or equipment, and can easily and synchronously complete the self-unclogging operation, resulting in good performance.

[0042] The pool body 1 has an inlet pipe 2 and an outlet pipe 3 fixedly installed on both sides, a cleaning rod 11 fixedly connected inside the pool body 1, and a power unit 9 fixedly installed on the right side of the pool body 1.

[0043] Fresh water is introduced through inlet pipe 2, wastewater is discharged from tank 1 through outlet pipe 3, and power unit 9 provides power to rotate aerator assembly 4.

[0044] The cylinder 41 is rotatably sleeved in the pool body 1, the gear 42 is fixedly sleeved on the outer surface of the cylinder 41, the arc-shaped opening 43 is opened on the outer surface of the cylinder 41 and is distributed around it, and a retaining ring is fixedly sleeved inside the cylinder 41.

[0045] By utilizing the degree of overlap between the arc-shaped opening 43 and the arc-shaped groove 62, the actual outlet diameter is controlled, and the oxygenation amount is controlled. The gear 42 achieves rotation adjustment by meshing with the power unit 9.

[0046] The simulation component 5 includes a U-shaped guide ring 51, a collar 52, and a flexible floating belt 53. The U-shaped guide ring is distributed around the outer surface of the cylinder 41 and is fixedly connected. The collar 52 is movably sleeved on the U-shaped guide ring 51, and the flexible floating belt 53 is fixedly connected to the top of the collar 52.

[0047] The simulation component 5 simulates floating objects such as aquatic plants, providing space for fish eggs to adhere together. At the same time, the arc-shaped opening 43 near the simulation component 5 ensures that the oxygen supply in the vicinity is maintained under a certain density of the simulation component 5, thereby improving the overall breeding effect.

[0048] The tube body 61 is rotatably sleeved inside the cylinder body 41. The arc-shaped groove 62 is opened on the outer surface of the tube body 61. The arc-shaped groove 62 corresponds one-to-one with the arc-shaped opening 43. The gear 63 is fixedly sleeved on the outer surface of the tube body 61 and located outside the pool body 1. The annular groove 64 is opened on the outer surface of the tube body 61. The internal cavity 65 is opened inside the tube body 61 and communicates with the arc-shaped groove 62. One end of the tube body 61 is sealed. The annular groove 64 is rotatably sleeved with the retaining ring.

[0049] By utilizing the rotation of the adjusting component 6 to adapt to the position of the oxygenation cylinder component 4, the outlet diameter can be adjusted through different angles to control the oxygenation rate and total volume. Furthermore, the cooperation between the retaining ring and the ring groove 64 maintains the stability of the adjusting component 6 and avoids lateral displacement. The gear 63 is driven by the meshing of the pushing component 7 to achieve lateral reciprocating control.

[0050] The pushing component 7 includes a toothed plate 71 and an electric push rod 72. The toothed plate 71 is meshed with a gear 63. The electric push rod 72 is fixed to the side of the pool body 1 by a bottom frame. The movable end of the electric push rod 72 is fixedly connected to the toothed plate 71 and pushes the toothed plate 71 to move back and forth.

[0051] By utilizing the lateral pushing force provided by the pushing component 7, the reciprocating pushing is achieved, thereby controlling the reciprocating rotation of the adjusting component 6.

[0052] The power unit 9 includes a servo motor and a gear three. The servo motor drives the gear three to rotate, and the gear three meshes with the gear one 42.

[0053] The dispensing assembly 8 includes a dispensing frame 81, a sleeve 82, and a connecting rod 83. Both ends of the dispensing frame 81 are fixedly connected to the connecting rod 83 and are also fixedly connected to the pool body 1 through the connecting rod 83. The sleeve 82 is fixedly connected to the front of the dispensing frame 81 and communicates with the inside of the dispensing frame 81. The other end of the sleeve 82 is movably sleeved on the outer end of the tube body 61. A sealing ring is nested in the inner wall of the sleeve 82 and is sleeved on the outer side of the tube body 61. The sleeve 82 communicates with the internal cavity 65.

[0054] The distribution component 8 ensures that the oxygen supply can still be maintained and directed to the adjustment component 6 even when the adjustment component 6 is rotating dynamically.

[0055] Among them, an oxygenation cylinder assembly 4 has a rotating filter section 10 fixedly sleeved on its outer surface. The rotating filter section 10 includes a rotating disk 101, a guide frame 102, and an arc-shaped filter groove 103. The rotating disk 101 is fixedly sleeved on the outer surface of the cylinder 41. The guide frame 102 is fixedly connected to the side of the rotating disk 101. The arc-shaped filter groove 103 is opened on the front of the rotating disk 101 and is connected to the guide frame 102. The liquid inlet end of the discharge pipe 3 is located on the rotation path of the guide frame 102.

[0056] By utilizing the rotation control process of the aeration cylinder assembly 4, the filter section 10 is rotated when needed. On the one hand, when it is misaligned with the discharge pipe 3, the filtration process is canceled to clean the internal sediment. On the other hand, when it is aligned with the discharge pipe 3, it is opened to achieve filtration and water exchange, preventing seedlings from escaping. Furthermore, during the rotation process, it comes into contact with the cleaning rod 11 through friction to complete the self-cleaning process.

[0057] A method for adjusting fish fry breeding ponds used for different fish fry breeding, comprising the following adjustment steps:

[0058] Step 1: When it is necessary to adapt to the breeding of different types of fish fry, according to the oxygen supply requirements of different types of fish fry, the push component 7 is activated, which causes the push component 7 to drive the adjustment component 6 to rotate, so that the position of the arc-shaped groove 62 and the arc-shaped opening 43 changes and gradually overlaps, thus increasing the oxygen supply. When it is necessary to reduce the oxygen supply, the position of the arc-shaped groove 62 and the arc-shaped opening 43 changes and gradually moves away, thus reducing the amount of oxygen input into the pond 1 through the arc-shaped opening 43.

[0059] Step 2: When some fish eggs need to be suspended in the pool 1, start the power unit 9 to make the aeration cylinder assembly 4 rotate, keep a set of simulation components 5 in the front, and at the same time, the simulation components on both sides are suspended on both sides under the buoyancy. This type of fish will attach the fish eggs to the flexible floating belt 53.
