Description

Technical Field

[0001] The present invention relates to the technical field of flounder farming, and specifically to a deep-water cage flounder farming device. Background Art

[0002] Flatfish, also known as flounder, is a general term for fish in the order Pleuronectiformes of Osteichthyes; the body is very laterally compressed, showing an oblong, oval or long tongue-like shape, with a maximum body length of up to 5 m; the bodies of adult fish are asymmetrical, with both eyes located on the left or right side of the head, the mouth is slightly protruding, the fins generally have no fin spines, the bases of the dorsal fin and anal fin are long, and are connected or not connected to the caudal fin, and are widely distributed in the warm waters of the major oceans.

[0003] The flounder is a type of flatfish and is a general term for animals in the family Bothidae. Like flatfish, the body is laterally compressed and asymmetrical, with both eyes on the left side, the mouth is anterior, the lower jaw protrudes, the edge of the preoperculum is free, the side with eyes is dark gray or has patches, and the side without eyes is white; the representative species is the Japanese flounder, also called the brown flounder. As an economic fish, the flounder has important farming value, and cages are required for large-scale farming of flounder.

[0004] When the existing cage farming devices are used for farming, since the initial state of farming is all fry, the mesh holes of the farming cages are relatively small. As the fry in the cages grow up, the disadvantages of the cages with small mesh holes gradually emerge. The cages with small mesh holes have a large resistance to water, and the water exchange speed between the water inside and outside the cage is slow, which is not conducive to the growth of the grown-up fry. At the same time, in the existing flounder farming, the fry all inhabit the bottom of the cage, and the area of the bottom of the cage is limited. Therefore, the number of fry that can be farmed in the same cage is small. In view of the above-mentioned problems, we provide a deep-water cage flounder farming device. Summary of the Invention

Specific embodiments

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, as Figures 1 - 3 shown, a deep-water net cage turbot farming device includes an inner net box 1, an adjusting component, an adjusting component and a sunshade component. The lower end of the inner net box 1 is fixedly connected to a bottom plate 14. Four sides of the upper end of the inner net box 1 are provided with fixing plates 2, and floating boxes 3 are installed on the fixing plates 2. One side of the upper end surface of the bottom plate 14 is fixedly connected to two installation vertical plates 6, and the other side of the upper end surface of the bottom plate 14 is fixedly connected to two installation strip blocks 7. A plurality of perching boards 8 are provided between the two installation strip blocks 7 and the two installation vertical plates 6. Both ends of the perching board 8 are fixedly connected to connecting end shafts 9, and the perching board 8 is rotationally connected to the installation vertical plates 6 and the installation strip blocks 7 through the connecting end shafts 9. The floating box 3 is of a hollow structure.

[0034] In this embodiment, during use, the density of the mesh holes of the net cage can be adjusted by the provided adjustment component. The provided adjustment component is used to adjust the state of the perching board 8. The multiple perching boards 8 provided inside the net cage facilitate the perching of fry, increasing the perching area inside the net cage. While increasing the breeding quantity, it also provides perching positions at different depths for the fry. The provided sunshade component can provide shade during use, creating a comfortable lighting environment for flounder. At the same time, the sunshade component can also be folded when not needed, which is convenient to use.

[0035] In one embodiment, as Figure 2 and 7 shown, the adjustment component is arranged on the inner net cage 1 and is used to change the mesh density. The adjustment component includes an outer net cage 5, which is sleeved on the inner net cage 1. The mesh size of the outer net cage 5 is the same as that of the inner net cage 1. Installation blocks 13 are provided at both upper ends of both sides of the outer net cage 5. Waterproof electric cylinders 4 are installed on both upper sides of both sides of the inner net cage 1, and the output ends of the waterproof electric cylinders 4 are fixedly connected to the installation blocks 13 respectively; the mesh holes of the inner net cage 1 and the outer net cage 5 are both rectangular; both the inner net cage 1 and the outer net cage 5 are made of stainless steel.

[0036] During adjustment, the outer net cage 5 is pulled up or down by the waterproof electric cylinder 4 to adjust the density of the mesh holes. When the mesh holes of the inner net cage 1 and the outer net cage 5 coincide, the mesh holes of the net cage at this time are large mesh holes, which is convenient for the breeding of adult fish. When the mesh holes of the inner net cage 1 and the outer net cage 5 are staggered, the mesh holes of the net cage at this time are small mesh holes, which is convenient for the breeding of juvenile fish. This enables the mesh holes of the net cage to be adjusted to large mesh holes when the fry grow up, which can improve the seawater exchange speed, is beneficial to the growth of adult fish, and reduces the resistance of the net cage in the seawater.

[0037] In one embodiment, as Figure 4 、 Figure 8 and Figure 9 shown, the adjustment component is arranged in the installation strip block 7 and is used to adjust the state of the perching board 8. The adjustment component includes an installation groove 27, which is opened inside the installation strip block 7. Adjustment gears 28 are fixedly connected to the positions where the connecting end shafts 9 at one end of the perching board 8 penetrate into the installation groove 27. A driving component for driving the connecting end shaft 9 to rotate in cooperation with the adjustment gear 28 is also provided in the installation strip block 7; the driving component includes an electric push rod 12, which is installed at the lower end position of the installation groove 27. The output end of the electric push rod 12 is fixedly connected to a driving strip 10, and a transmission tooth 11 for meshing with the adjustment gear 28 is provided at a position where the driving strip 10 is close to the adjustment gear 28.

[0038] During operation, the output end of the electric push rod 12 pushes out to drive the driving bar 10 to move. The movement of the driving bar 10 can drive the adjusting gear 28 to rotate, and the rotation of the adjusting gear 28 can adjust the state of the perching board 8. When the perching board 8 is in the vertical state, it is convenient for the fish feces to easily fall onto the net below and be cleaned out with the water flow. At the same time, in the vertical state, the fry can be separated from the perching board 8 to drive the fry to go for feeding. When the perching board 8 is in the horizontal state, it can reduce the sun's irradiation and thus lower the temperature to a certain extent. At the same time, in the tiled state, it is convenient for the fry to attach.

[0039] In one embodiment, as Figure 5 and Figure 6 shown, the sunshade assembly is arranged at the upper end of the inner net box 1 for shading sunlight. The sunshade assembly includes a support plate 15, and the support plate 15 is respectively fixedly connected to both sides of the inner net box 1. A sliding rod 24 is fixedly connected between the upper ends of the two support plates 15 on the same side. A fixing rib 23 is fixedly connected between one ends of the two sliding rods 24. A driving bar block 16 is also slidably connected between the two sliding rods 24. A number of support ribs 18 are arranged between the driving bar block 16 and the fixing rib 23 between the two sliding rods 24. A scissor holding frame 25 for maintaining the distance between the support ribs 18 is also arranged between the lower ends of the fixing rib 23 and the driving bar block 16. A sunshade net 17 covers the driving bar block 16, the support ribs 18 and the driving bar block 16. A moving assembly for driving the driving bar block 16 to move along the sliding rod 24 is also arranged at the lower end of the driving bar block 16.

[0040] During use, the sunshade net 17, the support ribs 18 and the driving bar block 16 provided can shade the net box during use, thereby providing a comfortable environment for the fry. At the same time, the moving assembly provided can fold the sunshade net 17 during use, so that shading or non-shading can be selected according to the weather conditions, which is convenient to use.

[0041] The moving assembly includes a mounting seat 26. The two mounting seats 26 are respectively fixedly connected to both ends of the lower end face of the driving bar block 16. A rotating shaft 19 is rotatably connected between the two mounting seats 26. Driving gears 20 are installed at both ends of the rotating shaft 19. A driving motor 21 for driving the rotating shaft 19 to rotate is also arranged on the mounting seat 26 at one end of the driving bar block 16. Rack bars 22 are fixedly connected to the positions below the sliding rods 24, and the rack bars 22 are respectively meshed with the driving gears 20.

[0042] During operation, the driving motor 21 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 drives the two driving gears 20 to rotate. The rotation of the driving gears 20 meshes with the rack bars 22 to move the driving bar block 16, and thus the sunshade net 17 can be unfolded and retracted. The provided support plate 15 can be used to maintain the distance between the support ribs 18.

[0043] In summary, during the cultivation of juvenile fish, the waterproof electric cylinder 4 is used to pull the outer net cage 5 upward, causing the mesh holes on the inner net cage 1 and the outer net cage 5 to stagger, turning the mesh holes of the net cage into small mesh holes. When the juvenile fish gradually grow up, the waterproof electric cylinder 4 can be used to drive the outer net cage 5 downward so that the mesh holes of the inner net cage 1 and the outer net cage 5 coincide, thereby making the small mesh holes of the net cage become large mesh holes, which can increase the seawater exchange speed and is beneficial to the growth of adult fish. At the same time, multiple habitat plates 8 are provided to facilitate the habitat of fry, increasing the habitat area inside the net cage. While increasing the breeding volume, different-depth habitat positions are provided for the fry. When feeding, the output end of the electric push rod 12 is pushed out to drive the drive bar 10 to move. The movement of the drive bar 10 can drive the adjustment gear 28 to rotate, and the rotation of the adjustment gear 28 can adjust the state of the habitat plate 8, thereby adjusting the horizontally placed habitat plate 8 to a vertical position, so that the fry attached to the habitat plate 8 can be driven down when feeding the fish. At the same time, the sunshade net 17, support ribs 18 and drive bar block 16 provided can shade the net cage during use, thereby providing a comfortable environment for the fry. When the sunshade net 17 needs to be folded, the drive motor 21 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 drives the two drive gears 20 to rotate. The rotation of the drive gears 20 meshes with the rack 22 to move the drive bar block 16, thereby realizing the retraction and expansion of the sunshade net 17.

[0044] The above is only a specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
