Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a targeted lysozyme releasing device and a disinfecting method for mandarin fish perch aquaculture parasites. Background Art

[0002] The Mandarin Perch (Siniperca chuatsi) aquaculture parasite-targeted lysozyme release device is an intelligent device designed to address parasite infection issues during Mandarin Perch aquaculture. Its core function is to achieve precise control of parasites through the targeted release of specific lysozymes. The device can release specific lysozymes for specific parasite species, which can destroy the cell walls or cell membranes of the parasites, thereby achieving the purpose of killing the parasites.

[0003] The above-mentioned existing technical solutions have the following defects: when spraying the breeding pond, the fixed nozzle can only cover a limited area. Directly below the nozzle, the lysozyme concentration at the edge or corner of the breeding pond is insufficient, and the lysozyme spreads unevenly during the spraying process, resulting in the parasites in some areas not being effectively killed, increasing the risk of recurrence.

[0012] Preferably, the water wheel is installed at the bottom of the movable block, a small gear is installed on the top of the water wheel, connecting shafts are provided on both sides of one end of the flow trough, and a gear set is provided on the outside of the connecting shaft.

[0014] A method for disinfecting parasites in aquaculture of mandarin fish by targeting a lysozyme release device comprises the following steps:

[0015] S1. Prepare the solvent: Select a specific targeted lysozyme based on the parasite species, prepare a lysozyme solution in the appropriate proportion, and place the solution in the storage tank of the device.

[0016] S2. Check the device: Check the remaining battery charge in the device. Then, based on the angle of sunlight, press the pressing plate to move the limit axis away from the limit hole. The support will no longer be fixed by the limit hole. By stretching the support, the tilt angle of the solar panel can be adjusted to align with the angle of sunlight. The absorbed sunlight is converted into electrical energy through the photoelectric effect and transmitted to the battery in the device for storage. After ensuring that the device is fully charged and can be used normally, place the base in the aquaculture pond.

[0017] S3. Activating the device: After the base is placed in the pond, the paddles are activated to rotate, driving the base to a designated area. The base then pumps the solution from the storage tank through a connecting pipe to the spray pipe, where it is sprayed into the pond. As the solution passes through the movable block and is discharged from the water inlet, it drives the water wheel to rotate. This, coupled with multiple gear sets, causes the spray pipe to swing back and forth within a specific angle, coordinated by a sliding ring and a stop rod, thereby expanding the solvent's spray range.

[0018] S4. Real-time monitoring: After the lysozyme solvent is released, samples are taken regularly for microscopic examination to detect parasite density and evaluate the effect of lysozyme.

[0019] Compared with the existing technology, the present invention has the following beneficial effects: the targeted lysozyme release device and method for disinfecting mandarin fish aquaculture parasites can realize automatic swing of the spray pipe while spraying the lysozyme solution, thereby increasing the solution coverage range and reducing costs. The swing range can also be adjusted, thereby enhancing the accuracy and adaptability of the device.

[0020] By providing a spraying structure and a water wheel inside the movable block, when the lysozyme solution enters the movable block, the water inlet is controlled by the diverter plate, and the solution is alternately directed from one inlet to the other, realizing the switching of the clockwise and counterclockwise rotation of the water wheel. The speed is gradually decelerated by the gear set, so that the spray pipe swings back and forth while spraying the solution. Therefore, the release device can evenly distribute the lysozyme, expand the coverage range, improve the contact efficiency between the lysozyme and the parasite, reduce the number of devices or the single release amount, and reduce the consumption and cost of lysozyme.

[0021] Furthermore, two sets of sliding rings are provided under the fixed block. By adjusting the position of the sliding rings, the stroke of the spacing between the protrusions is controlled, and the distance at which the stop rod touches the protrusions during rotation is changed, thereby achieving adjustable swing range of the spray pipe during spraying. When the breeding density of mandarin fish is high, the risk of parasite transmission increases, and the swing amplitude needs to be increased to quickly cover the entire pond. Conversely, when the density is low, the amplitude can be reduced to save lysozyme, thereby achieving precise adaptation to the breeding density. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-11 The targeted lysozyme release device and disinfecting method for mandarin fish culture parasites provided by the present invention include a base 1 and a storage box 4 arranged on the top of the base 1; a lifting structure 2 is provided at one end of the top of the base 1, and a solar panel 3 is installed on the top of the lifting structure 2, a spraying structure 5 is installed at the other end of the top of the base 1, and paddles 6 are provided on both sides of one end of the base 1, the lifting structure 2 includes a support 21 fixed to the top of the base 1, and the support 21 is located at the corner of the bottom of the solar panel 3, pillars 22 are provided inside the support 21, and the top of the pillars 22 are hinged with an articulated seat 24, and the bottom end of the solar panel 3 outside the articulated seat 24 is fixed with a slide groove 23, and the slide groove 23 and A sliding structure is formed between the hinge seats 24, and limiting holes 25 are provided on both sides of the pillars 22. Limiting grooves 212 are fixed on both sides of the support 21, and movable plates 214 are provided inside the limiting grooves 212. A sliding structure is formed between the movable plate 214 and the limiting grooves 212. The bottom end of the movable plate 214 is connected to the pressing plate 211. Limiting shafts 215 are installed on both sides of the support 21 inside the movable plate 214, and sliders 216 are welded to both ends of one side of the limiting shaft 215. Oblique grooves 217 are provided at both ends of the movable plate 214, and a sliding structure is formed between the oblique grooves 217 and the sliders 216. First springs 213 are installed at both ends of the movable plate 214.

[0036] Reference Figures 9-11As shown, when the angle of the solar panel 3 needs to be adjusted, the pressing plate 211 is pressed to drive the movable plate 214 fixed thereto to slide downward along the limiting groove 212. The side wall of the limiting groove 212 is provided with an inclined groove 217. When moving downward, the slider 216 is driven to slide along the inclined groove 217, so that the limiting shaft 215 fixed thereto is displaced outward, and the limiting shaft 215 is away from the limiting hole 25. The limiting hole 25 loses its limit and then directly moves upward to the support 22, so that one side of the solar panel 3 is lifted. When it is pulled to a suitable height, the approaching limiting hole 25 slides to the position of the limiting shaft 215, and the pressing plate 211 is in In a pressure-free state, the first spring 213 drives the movable plate 214 to return to its original position through the rebound force, drives the slider 216 to slide along the inclined groove 217, and the limiting shaft 215 is squeezed inwardly. When the limiting hole 25 slides to the position of the limiting shaft 215, the limiting shaft 215 is pushed into the limiting hole 25 instantly under the action of the rebound force, thereby fixing the pillar 22. At the same time, the linkage between the hinge seat 24 and the slide groove 23, combined with the position offset generated during the angle conversion, realizes the angle adjustment of the solar panel 3, improves the utilization rate of light energy, reduces the dependence on the battery capacity, and improves the stability of energy supply.

[0037] The spraying structure 5 includes a frame 51 fixed to the top of the base 1, and a spraying pipe 52 is installed at one end of the frame 51, the top of the spraying pipe 52 is connected to a movable block 55, and a fixed block 54 is installed at the top of the movable block 55, and the top of the fixed block 54 is connected to a connecting pipe 53. A water wheel 57 is provided inside the movable block 55, and a diversion channel 555 is provided at one end of the bottom of the movable block 55, and water inlets 554 are provided on both sides of the diversion channel 555. The water wheel 57 is installed at the bottom of the movable block 55, and a small gear is installed on the top of the water wheel 57. Connecting shafts 573 are provided on both sides of one end of the flow groove 551, and gear sets 571 are provided on the outside of the connecting shafts 573. The gear sets 571 are provided with several groups, and the gear sets 571 are composed of large and small gears, and the large and small gears are staggered and meshed. A spur gear 572 is installed on the top of the movable block 55, and the spur gear 572 and the gear set 571 are meshed and connected;

[0038] Reference Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, when the solution is sprayed, the solution enters the movable block 55 from the fixed block 54, flows out from the water inlet 554, and impacts the blades of the water wheel 57 under the restriction of the diversion channel 555, thereby transferring part of the kinetic energy of the solution to the water wheel 57, causing it to rotate at high speed. A small gear is installed on the top of the water wheel 57, and the small gear rotates with the gear set 571. When the water wheel 57 rotates, the gear set 571 rotates synchronously. Through the meshing design of the large and small gears in the several groups of gear sets 571, the large gear is always driven by the small gear to rotate, completing the gradual deceleration. The output of the slower speed is transmitted to the final spur gear 572, so that the movable block 55 and the spray pipe 52 connected thereto can rotate, so that the spray pipe 52 can swing while spraying;

[0039] A stop rod 58 is installed on one side of the movable block 55. A sliding ring 56 is sleeved on the bottom of the fixed block 54. There are two sets of sliding rings 56, and the sliding rings 56 are symmetrically distributed about the center point of the movable block 55. A convex tooth 565 is provided at the bottom end of the fixed block 54 in the center of the sliding ring 56. A dial plate 561 is fixed to the outer wall of the sliding ring 56. A small ring 562 is provided in the center of the sliding ring 56, and fine teeth 564 are provided on the inner wall of the small ring 562. The fine teeth 564 and the convex teeth 565 are meshed with each other. A protrusion 563 is provided inside the sliding ring 56.

[0040] Reference Figure 4 and Figure 5 As shown, when the swing range needs to be controlled, an incomplete small ring 562 is provided on the sliding ring 56. A group of fine teeth 564 is provided inside the small ring 562, which engages with the convex teeth 565 under the fixed block 54. Since the small ring 562 is incomplete and thus has a certain elasticity, the dial plates 561 on the two sets of sliding rings 56 are pushed toward the middle or to the sides. A slight pressure can overcome the engagement resistance between the fine teeth 564 and the convex teeth 565. By pressing the dial plates 561, the position of the convex blocks 563 can be adjusted to control the spacing between the convex blocks 563 on the two sets of sliding rings 56. The stop rod 58 moves within the spacing. By adjusting the sliding rings 56, the swing range can be reduced or increased.

[0041] The bottom end of the stop rod 58 is provided with a pressure plate 582, and the bottom of the pressure plate 582 is installed with a diverter plate 581. The diverter plate 581 is set at the top of the water inlet 554. A support plate 583 is fixed in the movable block 55 at the bottom of the diverter plate 581.

[0042] Reference Figure 4 、 Figure 6 and Figure 8As shown, a diverter plate 581 is provided above the water inlet 554, and a pressure plate 582 is provided below the stop rod 58. The pressure plate 582 is located in the through groove on the diverter plate 581, and the diverter plate 581 between the two water inlets 554 is controlled by the support plate 583. The purpose of the diverter plate 581 is to switch the solution alternately from one water inlet 554 to the other water inlet 554, ensuring that only one water inlet 554 is open and the other water inlet 554 is closed at any time. Water entering from one side rotates the water wheel 57 clockwise, while water entering from the other side rotates the water wheel 57 counterclockwise, thereby driving the stop rod 58 to rotate within the gap between the protrusions 563. When the stop rod 58 reaches the end of its rotation, it is pushed back in the opposite direction by the protrusion 563, and the diverter plate 581 is driven to rotate via the pressure plate 582, closing the water inlet 554 on one side and simultaneously opening the water inlet 554 on the other side, thereby changing the rotation direction of the water wheel 57. Repeated switching enables the spray pipe 52 to swing back and forth.

[0043] The movable block 55 is provided with a flow groove 551 inside, and a second spring 552 is installed inside the flow groove 551, and a sealing gasket 553 is provided on the top of the second spring 552;

[0044] Reference Figure 4 As shown, a flow groove 551 is provided inside the movable block 55. When the water pressure inside the movable block 55 exceeds a certain level, the second spring 552 is compressed, pushing the sealing gasket 553 open to allow the solution to flow into the flow groove 551, bypass the water wheel 57 and enter the spray pipe 52, thereby releasing excess pressure to ensure that the spray assembly operates within a safe limit.

[0045] A method for disinfecting parasites in aquaculture of mandarin fish by targeting a lysozyme release device comprises the following steps:

[0046] S1. Prepare the solvent: Select specific targeted lysozyme according to the parasite species, prepare the lysozyme solution in proportion, and place the solution inside the storage tank 4 of the device;

[0047] S2. Check the device: Check the remaining battery charge in the device. Then, according to the angle of sunlight, press the pressing plate 211 to move the limiting shaft 215 away from the limiting hole 25. The support 22 loses the fixation of the limiting hole 25. By stretching the support 22, the tilt angle of the solar panel 3 is adjusted so that it is opposite to the angle of sunlight. The absorbed sunlight is converted into electrical energy through the photoelectric effect and transmitted to the battery in the device for storage. After ensuring that the device is fully charged and can be used normally, the base 1 is placed in the aquaculture pond.

[0048] S3. Starting the Device: After base 1 is placed in the pond, paddle blades 6 are activated to rotate, causing base 1 to float to a designated area. The solution in storage tank 4 is then pumped through connecting pipe 53 to spray pipe 52 for spraying into the pond. As the solution passes through movable block 55 and is discharged from water inlet 554, it drives water wheel 57 to rotate. This, in turn, drives spray pipe 52 through multiple gear sets 571 to swing. The sliding ring 56 and stop rod 58 cooperate to cause spray pipe 52 to swing back and forth within a specified angle, thereby expanding the solvent's spraying range.

[0049] S4. Real-time monitoring: After the lysozyme solvent is released, samples are taken regularly for microscopic examination to detect parasite density and evaluate the effect of lysozyme.
