Description

Technical Field

[0001] This utility model relates to the field of grouper aquaculture technology, specifically to a culture pond for river grouper aquaculture. Background Technology

[0002] The stream rockfish is a type of freshwater rockfish, but it's a special species that only inhabits small streams. It only lives in clean water and has very high water quality requirements. Also known as the smooth-lipped fish, it lives in the crevices of rocks in streams and ravines in southern mountainous areas, or at the bottom of deep pools. Its body is grayish-black with distinct black markings, and it has a barbel on each side of its mouth. Adults are about 12 to 15 centimeters long and weigh about 50 grams, with a maximum of 150 grams. It feeds on stoneworms, small aquatic animals, and microorganisms found in streams. It is aesthetically pleasing, robust, disease-resistant, and likes to jump. Currently, one of the main methods of artificial breeding of stream rockfish is in natural ponds... Under pond conditions, simulating the natural growth conditions of stream grouper, the stream grouper are allowed to breed naturally in the pond. The fry obtained from breeding are then harvested manually. This method is relatively simple, but since stream grouper are carnivorous fish, it is necessary to separate the parent fish and fry in a timely manner during the breeding process. It is also necessary to separate fry of different sizes in a timely manner. In practice, multiple separation steps are required, and manual harvesting is labor-intensive. Moreover, manual harvesting requires a high frequency and skill in harvesting fry. If the fry are not harvested thoroughly, larger fry in the pond will prey on smaller fry, greatly reducing the survival rate of the fry. Utility Model Content

[0017] Reference Figures 1 to 4 As shown, this utility model provides a breeding pond for culturing grouper, including: a breeding pond body 4 and a main electric rod 12. Guide plates 6 are symmetrically connected to the lower surface of the breeding pond body 4, and a transfer box 1 is slidably connected to the lower surface of the breeding pond body 4 via the guide plates 6. A separation port 2 is opened on one side of the bottom of the breeding pond body 4, and a sealing groove is opened on the side of the separation port 2. A secondary electric rod 5 is fixedly connected inside the sealing groove, and a sealing plate 3 is slidably connected to the sealing groove via the secondary electric rod 5. Simultaneously, the main electric rod 12 is symmetrically connected to the upper end of the inner side of the breeding pond body 4. The telescopic rod of 2 is fixedly connected to the movable frame 7, and the filter plate 8 is fixedly connected to the inner cavity of the movable frame 7. The separation frame 11 is movably connected to the upper surface of the movable frame 7, and the movable grooves 10 are symmetrically opened on the inner side of the cultivation tank 4. The main screw 9 is movably connected to the movable groove 10 through the sealed bearing, and one end of the main screw 9 is connected to the main motor 14 through the coupling. The main motor 14 is fixedly connected to the outer side of the cultivation tank 4. At the same time, the movable block 16 is slidably connected to the movable groove 10 through the screwed main screw 9, and the separation plate 13 is slidably connected to the inside of the cultivation tank 4 through the movable block 16.

[0018] In this embodiment, after the broodstock of stream grouper has grown into fry in the rearing tank 4, it needs to be separated from the fry. First, the main electric rod 12 is activated. The telescopic rod of the main electric rod 12 drives the fixedly connected movable frame 7 and filter plate 8 to move upward. The movable frame 7 and filter plate 8 then push the separation frame 11 to move upward synchronously. This causes the broodstock of stream grouper in the rearing tank 4 to be pushed upward by the separation frame 11, while the fry detach from the separation hole of the separation frame 11. Subsequently, the broodstock of stream grouper swims at the upper end of the rearing tank 4, while the fry swim at the lower end. When workers need to further transfer the broodstock of stream grouper, they only need to lift the separation frame 11, effectively reducing the labor intensity of the workers. When it is necessary to separate large and small fry, the main motor 14 is activated. The main motor 14 drives the main screw 9 to rotate through the coupling. The main screw 9 pushes the separation plate 13 to move synchronously through the screwed movable block 16. Subsequently, the separation plate 13... Larger fry can be pushed to one side of the rearing tank 4, leaving only smaller fry swimming on both sides. Then, the auxiliary electric rod 5 is activated, causing the extension rod of the auxiliary electric rod 5 to move the sealing plate 3, opening the separation port 2. Liquid in the rearing tank 4 flows into the transfer box 1 through the separation port 2, while the smaller fry are transferred to the transfer box 1 along with the water flow, leaving only the larger fry in the rearing tank 4. The reset switch of the auxiliary electric rod 5 is then activated, closing the separation port 2 again with the sealing plate 3. The solenoid valve of the inlet pipe is opened, allowing a certain amount of water to accumulate in the rearing tank 4. Then, the solenoid valve of the outlet pipe is opened, causing the water in the rearing tank 4 to flow. The reset switch of the main motor 14 is activated, and the separation plate 13 resets under the action of the moving block 16 and the main screw 9. Workers can then remove the transfer box 1 and transfer the smaller fry to a suitable location, effectively improving the fry survival rate and reducing the workload of workers.

[0019] As a preferred embodiment, the two sets of moving grooves 10 symmetrically opened on the inner side of the cultivation tank 4 are both elongated structures, and the length of the moving grooves 10 is less than the width of the inner cavity of the cultivation tank 4. A receiving groove is opened on the side of the inner cavity of the cultivation tank 4 near the moving grooves 10. The receiving groove has a square structure, and the size of the receiving groove is compatible with that of the separation plate 13.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The opening of the moving trough 10 can not only help enhance the stability of the moving block 16 and the separation plate 13 during movement, but also limit the range of movement of the moving block 16 and the separation plate 13, ensuring that large-sized fish fry can still swim in a suitable space during the separation process, avoiding the problem of large-sized fish fry squeezing each other, and ensuring the survival rate of large-sized fish fry.

[0021] As a preferred embodiment, the inlet pipe and the outlet pipe are fixedly connected to the end faces of the two ends of the cultivation tank 4, respectively, and the inlet pipe and the outlet pipe are staggered. A separation port 2 is opened on the bottom of the cultivation tank 4 near the outlet pipe, and the separation port 2 has a square structure.

[0022] In this embodiment, as Figure 1 and Figure 3 The location and distribution of the inlet and outlet pipes allow water to flow from one side of the rearing tank 4 to the other, which helps to improve the separation effect between large and small fry. The opening of the separation port 2 facilitates the transfer of small fry.

[0023] In a preferred embodiment, the sealing groove on the side of the separation port 2 has a rectangular structure, and the cross section formed by the combination of the separation port 2 and the sealing groove has a cross-shaped structure. The sealing plate 3 has a square structure, and the surface of the sealing plate 3 is covered with a sealing layer. At the same time, the dimensions of the sealing plate 3 and the sealing groove are compatible.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sealing layer is made of soft rubber, which can effectively enhance the sealing performance of the connection between the sealing plate 3 and the sealing groove. At the same time, the cooperation between the auxiliary electric rod 5 and the sealing plate 3 allows the separation port 2 to be easily opened and closed, thus facilitating the batch transfer of fish fry of different sizes inside the cultivation pond 4.

[0025] In a preferred embodiment, the movable frame 7 has a U-shaped structure, the outer side of the movable frame 7 is adapted to the size of the inner cavity of the cultivation tank 4, and the filter plate 8 fixedly connected to the inner cavity of the movable frame 7 has a rectangular structure. At the same time, the size of the filter holes on the surface of the filter plate 8 is larger than the size of the separation holes on the surface of the separation plate 13.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The dimensions of the movable frame 7 and the inner cavity of the breeding tank 4 are matched, which can help enhance the stability of the movable frame 7, the filter plate 8 and the separation frame 11 when they move, and also reduce the chance of small fish fry crawling into the connecting seam, thereby helping to improve the survival rate of the fish fry.

[0027] In a preferred embodiment, multiple sets of positioning blocks 15 are fixedly connected to the two sides of the upper surface of the movable frame 7 in parallel and at equal intervals. The multiple sets of positioning blocks 15 are all cylindrical in shape, and the upper surface of the positioning blocks 15 is spherical. Meanwhile, the separation frame 11 connected movably inside the cultivation pool 4 is concave in shape, and the lower surface of the separation frame 11 is provided with positioning grooves corresponding to the positions of the positioning blocks 15.

[0028] In this embodiment, as Figure 3 and Figure 4 The positioning block 15 and the positioning groove can help enhance the stability of the connection between the separation frame 11 and the moving frame 7, avoid the problem of the separation frame 11 shaking or shifting in the cultivation tank 4, and thus ensure that the separation frame 11 can move up and down smoothly in the cultivation tank 4.

[0029] In a preferred embodiment, the two sets of guide plates 6 fixedly connected to the lower surface of the cultivation tank 4 are both L-shaped, and the transfer box 1 slidably connected to the lower surface of the cultivation tank 4 has a U-shaped cross section. The upper surface of the transfer box 1 is provided with guide grooves corresponding to the positions of the guide plates 6, and the sealing strip fixedly connected to the upper surface of the transfer box 1 has a U-shaped structure.

[0030] In this embodiment, as Figure 3 and Figure 4 The guide plate 6 is designed to assist in the loading and unloading of the transfer box 1. The bent part of the guide plate 6 can limit the movement range of the transfer box 1, ensuring that the transfer box 1 can move directly below the separation port 2. At the same time, the sealing strip is made of soft rubber, which can help enhance the sealing of the connection between the transfer box 1 and the lower surface of the cultivation tank 4, reducing the chance of accidental liquid spillage.

[0031] The breeding pond for river grouper of this utility model, through the cooperation of the main electric rod 12, the moving frame 7, the separation frame 11, the main lead screw 9, the main motor 14 and the separation plate 13, can quickly separate the river grouper parent fish and the fry of different sizes, thereby effectively improving the survival rate of the fry and also helping to reduce the labor intensity of workers.
