Description

Technical Field

[0001] This utility model relates to the field of aquaculture box technology, and in particular to a space-adjustable fish fry aquaculture box. Background Technology

[0002] Fish fry rearing is a crucial link in the aquaculture industry, directly affecting the quality of adult fish and the profitability of aquaculture. The fry stage is characterized by rapid growth, high environmental sensitivity, and unique feeding behaviors, placing high demands on the spatial layout and ease of management of rearing containers.

[0003] Traditional fish tanks typically use a fixed volume design, which cannot be dynamically adjusted according to changes in the length and density of the fish fry. In the initial stocking stage, due to the small size of the fish fry, the fixed space can easily lead to water waste and increase the cost of feeding. As the fish fry grow rapidly, overcrowding intensifies, resulting in uneven distribution of dissolved oxygen and accelerated accumulation of excrement, which can induce stress or spread of diseases.

[0004] To address these issues, a space-adjustable fish fry rearing box is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-5 This utility model provides a space-adjustable fish fry rearing box, comprising:

[0026] The upper frame 1 has a motor 2 fixedly connected to it. A lower frame is fixedly connected to the bottom of the upper frame 1. The lower frame includes a first fixed rod 3, a second fixed rod 4, a third fixed rod 5, and a fourth fixed rod 6. The first fixed rod 3 and the third fixed rod 5 are arranged in parallel. A moving rod 7 is slidably connected between the first fixed rod 3 and the third fixed rod 5. The second fixed rod 4 is fixedly connected between the first fixed rod 3 and the third fixed rod 5. The fourth fixed rod 6 is fixedly connected between the first fixed rod 3 and the third fixed rod 5. A breeding box 8 is fixedly connected to the second fixed rod 4. The second fixed rod 4 is fixedly connected to one side of the breeding box 8. Two sides of the breeding box 8 are slidably connected to the first fixed rod 3 and the third fixed rod 5, respectively. The other side of the breeding box 8 is fixedly connected to the moving rod 7. Several floats 9 are fixedly connected to the bottom of the upper frame 1. The motor 2 is driven by the moving rod 7.

[0027] In this device, the upper frame 1 floats on the water surface via floats 9. The breeding box 8 is woven from flexible materials such as polyethylene, polyvinyl chloride filaments, or nylon thread. In this embodiment, the breeding box 8 is a cuboid with an open top and has four sides. One side is fixedly connected to the second fixed rod 4, two opposing sides are slidably connected to the first fixed rod 3 and the third fixed rod 5, and the remaining side is fixedly connected to the moving rod 7. The motor 2 moves the moving rod 7, thereby adjusting the size of the breeding box 8 to expand or shrink it. When the fish fry are small, the motor 2 drives the moving rod 7 to move, reducing the space of the breeding box 8. As the fish fry grow, the motor 2 drives the moving rod 7 to move, expanding the breeding box 8 to accommodate the growth of the fish fry.

[0028] In a further optimized design, two tracks 10 are fixedly connected to the upper surface of the upper frame 1. The two tracks 10 are arranged opposite each other on the upper frame 1 and are parallel to each other. Slider 11 is slidably connected to the tracks 10. A reinforcing plate 12 is fixedly connected between the two sliders 11. The reinforcing plate 12 is fixedly connected to the moving rod 7. The motor 2 is connected to the reinforcing plate 12 for transmission.

[0029] The slider 11 moves on the track 10, and the motor 2 drives the reinforcing plate 12 to move. The slider 11 makes the reinforcing plate 12 move more flexibly.

[0030] The scheme is further optimized. Two support plates 13 are fixedly connected to the upper frame 1. A threaded rod 14 is rotatably connected between the two support plates 13. The output shaft of the motor 2 is fixedly connected to the threaded rod 14. A threaded hole is opened on the reinforcing plate 12, and the threaded rod 14 is threadedly connected in the threaded hole.

[0031] The threaded rod 14 is rotatably connected between the two support plates 13. The motor 2 drives the threaded rod 14 to rotate, and when the threaded rod 14 rotates, it will cause the reinforcing plate 12 to move.

[0032] The scheme is further optimized by fixing several first connecting plates 15 to the reinforcing plate 12, and first connecting plates 15 are provided with first connecting holes. Several second connecting plates 16 are fixedly connected to the moving rod 7, and second connecting plates 16 are provided with second connecting holes. Ropes 17 are fixedly connected between the first connecting holes and the second connecting holes.

[0033] Rope 17 connects the first connecting plate 15 and the second connecting plate 16 together, thereby connecting the reinforcing plate 12 and the moving rod 7 together.

[0034] The scheme is further optimized by slidably connecting the first sleeve 18 to both the first fixed rod 3 and the third fixed rod 5, and fixing both ends of the moving rod 7 to the first sleeve 18.

[0035] The first sleeves 18 on the first fixed rod 3 and the third fixed rod 5 can both slide, and the sliding connection between the moving rod 7 and the first fixed rod 3 and the third fixed rod 5 is realized through the first sleeves 18.

[0036] The scheme is further optimized by having several second sleeves 19 slidably connected to the first fixed rod 3 and the third fixed rod 5. A third connecting plate 20 is fixedly connected to the second sleeve 19. A third connecting hole 21 is opened on the third connecting plate 20. The breeding box 8 is fixedly connected to the third connecting hole 21.

[0037] The third connecting plate 20 on the second sleeve 19 is used to connect the breeding box 8. The second sleeve 19 facilitates the contraction or expansion of the breeding box 8.

[0038] In a further optimized design, several fourth connecting plates 22 are fixedly connected to the second fixed rod 4. The fourth connecting plates 22 have fourth connecting holes. The breeding box 8 is fixedly connected to the fourth connecting holes. Several fifth connecting plates 23 are fixedly connected to the moving rod 7. The fifth connecting plates 23 have fifth connecting holes 24. The breeding box 8 is fixedly connected to the fifth connecting holes 24.

[0039] The fourth connecting plate 22 on the second fixed rod 4 is used to connect the breeding box 8, and the fifth connecting plate 23 on the moving rod 7 is also used to connect the breeding box 8.

[0040] The scheme is further optimized. The track 10 includes a base plate 25, on which a dovetail block 26 is fixedly connected. A dovetail groove is opened on the slider 11, and the dovetail block 26 is located in the dovetail groove. The second fixing rod 4 and the fourth fixing rod 6 are both fixedly connected to the upper frame 1 through connecting rods.

[0041] The dovetail block 26 and the dovetail groove work together to prevent the slider 11 from disengaging.

[0042] Before using this device, one side of the breeding box 8 is fixedly connected to the fourth connecting plate 22 on the second fixed rod 4. Then, the two sides of the two breeding boxes 8 are fixedly connected to the third connecting plate 20, so that the breeding box 8 can slide on the first fixed rod 3 and the third fixed rod 5 through the second sleeve 19. Finally, the remaining side is fixedly connected to the fifth connecting plate 23 on the moving rod 7. When in use, the threaded rod 14 is rotated by the motor 2. When the threaded rod 14 rotates, the reinforcing plate 12 will move, thereby expanding or shrinking the breeding box 8.
