[0002] In the traditional octopus larvae breeding process, PVC pipes of any number and any diameter are usually used as octopus larvae shielding and breeding devices. These devices often roll with the water flow at the bottom of the cement pool, causing the octopus larvae originally living inside to escape in fear and inkjet stress; at the same time, the rolling of the PVC pipes will cause squeezing and abrasions to the octopus larvae, causing injury and death of the octopus larvae; too many PVC pipes will cause water flow obstruction when cleaning the cement pool, making it difficult to clean the cement pool; too few PVC pipes will easily cause octopus larvae to compete for shielding and breeding devices, causing physical damage and physical exhaustion, resulting in breeding losses; multiple octopus larvae PVC pipes enter from the openings at both ends, entangled in the pipes, causing injury and death of the octopus larvae.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an octopus larvae breeding device, wherein the housing (1) is a frame structure, the four corners of the housing are fixedly connected to a limiting column (2), and a plurality of partitions are installed on the limiting column for horizontal sliding, and an adjustment component is arranged between the partitions for adjusting the distance between adjacent partitions, and a breeding mechanism is arranged on each partition;

[0029] The four corners of the partition are provided with connecting blocks (13), the connecting blocks are slidably arranged with a limiting column, and a reset component is sleeved on the limiting column between the upper and lower connecting blocks;

[0030] The adjustment assembly comprises a fixing frame, a bidirectional threaded rod (8) and a connecting rod. The fixing frame is installed on both sides of the upper surface of the partition. The bidirectional threaded rod is horizontally installed on the fixing frame. A sleeve (10) is symmetrically threadedly installed on the bidirectional threaded rod. A connecting rod is installed on the sleeve. The other end of the connecting rod is connected to the lower surface of the upper partition. One end of the bidirectional threaded rod is connected to a driving assembly.

[0031] Specifically, a limiting column 2 is fixedly connected inside the shell 1, which is used to provide a sliding limiting function for the first partition 3 and the second partition 4 to ensure the stability of the partition and the accuracy of adjustment. The first partition 3 and the second partition 4 are arranged inside the shell 1 to provide a multi-layer habitat unit to meet the breeding needs of octopus larvae. The outer walls of the first partition 3 and the second partition 4 are both provided with limiting components to constrain the sliding position of the partition to prevent the partition from tilting or position shifting during the adjustment process. An adjustment component is arranged between the first partition 3 and the second partition 4 to flexibly adjust the distance between the two partitions, so as to adjust the breeding space according to the growth stage of the octopus larvae. A slot 29 is provided inside the shell 1 to provide water circulation and maintain the suitability of the breeding environment. A PVC pipe 28 is arranged on the top of the first partition 3 and the second partition 4 as a habitat unit for the octopus larvae to facilitate the stay and life of the octopus larvae. A handle 5 is fixedly connected to the top of the shell 1;

[0032] The adjustment component includes a connecting rod 6, one end of which is rotatably connected to the bottom of the second partition 4, and the force is transmitted by rotation, which is convenient for the smooth adjustment of the partition. One end of the connecting rod 6 is rotatably connected to a sleeve 10, and the sleeve 10 has a thread inside. The sleeve 10 is equipped with a bidirectional threaded rod 8. The design of the bidirectional threaded rod 8 can realize the linear movement of the sleeve 10, thereby driving the connecting rod 6 to support the partition, and then adjusting the height of the second partition 4. The limit assembly includes a connecting block 13, one side of which is fixedly connected to the outer wall of the first partition 3 and the second partition 4, and is used to tightly match the partition with the limit column 12 to ensure the smooth sliding of the partition during the adjustment process. The top of the first partition 3 is fixedly connected to the limit block 17 and the limit block 2 11, and the limit block 17 and the limit block 2 11 are used to constrain the motion range of the adjustment component to ensure the stability and safety of the adjustment process. The outer wall of the limit block 2 11 is provided with a driving component, and the driving component is used to provide a power source, so that the partition adjustment is more efficient. The connecting block 13 is slidably connected to the outer wall of the limit column 12, and provides an adjustable motion trajectory for the partition by sliding. The outer wall of the limit column 12 is provided with a reset component, and the reset component enables the partition to automatically return to its position during the adjustment process by providing elastic support force, thereby enhancing the convenience of the device. The driving component includes a waterproof motor 9, and the outer wall of the waterproof motor 9 is fixedly connected to the outer wall of the limit block 11, which is used to drive the rotation of the bidirectional threaded rod 8 to achieve precise adjustment of the partition. The output end of the waterproof motor 9 is connected to one end of the bidirectional threaded rod 8 to ensure efficient power transmission. The reset component includes a first spring 12, and the interior of the first spring 12 is sleeved on the outer wall of the limit column 2 to provide the necessary elastic support force for the partition. Both ends of the first spring 12 are fixedly connected between the connecting blocks 13, and through the elastic reset function, the partition can quickly return to its original position after adjustment, further improving the convenience of operation of the device;

[0033] Specifically, when adjusting the spacing between the first partition 3 and the second partition 4, the output end of the waterproof motor 9 drives the bidirectional threaded rod 8 to rotate, and the rotation of the bidirectional threaded rod 8 drives the sleeve 10 to move linearly in the opposite or opposite directions along the outer wall of the bidirectional threaded rod 8. The sleeve 10 transmits the motion through the connected connecting rod 6, so that the connecting rods 6 on both sides move synchronously, thereby promoting the precise adjustment of the spacing between the first partition 3 and the second partition 4. Furthermore, during the adjustment of the spacing between adjacent partitions, the movement of the sleeve 10 can flexibly adapt to different layer spacing requirements. The adjustment structure of each layer operates independently, so that the device can adjust the spacing between the partitions of each layer separately, and flexibly meet the needs of the multi-layer structure. In addition, the first partition 3 and the second partition 4 are reliably limited on the outer wall of the limiting column 2 through the connecting block 13, which effectively avoids the dislocation or sliding caused by vibration or external force during the adjustment process. The design of the connecting block 13 further ensures the stability of the partition movement. At the same time, the tension of the first spring 12 provides a lasting and reliable support for the second partition 4, so that it can always maintain smooth movement during the adjustment process to avoid shaking or tilting, thereby achieving the effect of flexibly adjusting the spacing between each layer of partitions, improving the adaptability and operating accuracy of the device, and the material used in the device is made of waterproof and corrosion-resistant materials to improve the durability of the breeding device in seawater. The spacing between the partitions can be different depending on the breeding period, and the spacing between the partitions is set between 240mm+4×the length of the octopus larvae (unit: mm) and 240mm+6×the length of the octopus larvae.

[0034] The breeding mechanism includes a support plate 14, and a plurality of support plates 14 are detachably installed on the top of the first partition plate 3. A slide groove 30 is formed on the upper side of the support plate 14, and a connecting plate 15 is slidably installed in the slide groove. A slider 31 is formed on one side of the connecting plate, and the slider is installed in conjunction with the slide groove. At the same time, the setting of the support plate is used to provide a stable installation foundation for the connecting plate 15 and related components to ensure that the device has sufficient support strength during use. The outer wall of the connecting plate 15 is fixedly connected with a support rod 19, and the support rod 19 is used to provide a support point for the rotation of the connecting rod three 21, and at the same time ensure the stability of the operation of the device. The connecting plate 15 is internally slidably connected with a limiting column 16. The limiting column 16 slides to enable the special-shaped rod 17 to flexibly adjust its position, thereby adapting to different operating requirements. One end of the limiting column 16 is fixedly connected with a special-shaped rod 17, and the special-shaped rod 17 is used as the core component of the adjustment and clamping structure to transmit the adjustment force of the device. A third spring 27 is arranged inside the connecting plate 15, and one end of the third spring 27 is fixedly connected to the other end of the limiting column 16. The third spring 27 is used to provide elastic support force, so that the limiting column 16 can quickly reset after releasing the force, thereby improving the convenience and stability of operation. The other end of the third spring 27 is fixedly connected to the inside of the connecting plate 15. Through the elastic action of the spring, the reset efficiency of the special-shaped rod 17 is enhanced. A guide groove 18 is provided inside the special-shaped rod 17. The guide groove 18 provides a track for the sliding of the guide column 26, thereby ensuring the directional stability of the guide column 26 during the movement. A guide column 26 is arranged inside the special-shaped rod 17. The guide column 26 is slidably connected inside the guide groove 18. The flexible adjustment of the special-shaped rod 17 is realized by sliding cooperation, and the working efficiency of the device is further improved. A connecting rod 3 21 is fixedly connected to one end of the guide column 26. The connecting rod 3 21 is used as a connecting component, and the movement of the guide column 26 is transmitted to the clamping plate 22 through its rotation function. The connecting rod 3 21 is internally connected to the rotating shaft 1 20, one end of which is fixedly connected to the inside of the support rod 19, and the rotating shaft 1 20 provides a fulcrum for the rotation of the connecting rod 3 21, thereby ensuring the smoothness of motion transmission. The other end of the connecting rod 3 21 is fixedly connected to the rotating shaft 25, and the outer wall of the rotating shaft 25 is rotatably connected to the clamping plate 22. The clamping plate 22 can be flexibly rotated through the connection of the rotating shaft 25, and provides reliable support for the clamping of the PVC pipe 28. The sphere 24 is slidably connected to the inside of the clamping plate 22, and the sphere 24 fits the outer wall of the PVC pipe 28. Through its mobility, it can adapt to the surface of the pipe body of different sizes, thereby improving the application range of the device. A second spring 23 is arranged inside the clamping plate 22, and one end of the second spring 23 is fixedly connected to the inside of the clamping plate 22. The second spring 23 provides tension support to keep the sphere 24 always in a fit state with the PVC pipe 28. The other end of the second spring 23 is fixedly connected to the outer wall of the sphere 24, and the clamping effect is further enhanced by the action of the spring force, thereby ensuring the fixing reliability of the PVC tube 28 and improving the ability of the device to adapt to tubes of different sizes;

[0035] Specifically, when the PVC pipe 28 needs to be clamped and installed, the operation is simple and convenient. You only need to insert the special-shaped rod 17 into the device for operation. The special-shaped rod 17 is precisely limited on the inner wall of the connecting plate 15 by the limiting column 2 16, and the third spring 27 is compressed and stored during the insertion process. Then, the special-shaped rod 17 slides along the guide column 26 in the guide groove 18, and the guide column 26 completes the rotation with the rotating shaft 1 20 as the center through the movement of the connecting rod 3 21. The other end of the rotating shaft 1 20 drives the clamping plate 22 to gradually close through the linkage with the rotating shaft 2 25, so as to achieve a stable clamping of the PVC pipe 28. When the special-shaped rod 17 is released, the restoring force of the third spring 27 causes the special-shaped rod 17 to reset, and the clamping plate 22 is automatically adjusted to a fixed position, thereby firmly fixing the PVC pipe 28. One end of the PVC tube 28 is sealed and the other end can be used to place octopus larvae and seedlings. At the same time, a sphere 24 is designed inside the clamp 22. The sphere 24 can fit tightly against the outer wall of the PVC tube 28. The continuous tension support provided by the second spring 23 enables the clamp 22 to flexibly adapt to PVC tubes 28 of different diameters. Such a structural design not only enhances the adaptability of the device to PVC tubes 28 of multiple specifications, but also effectively avoids the occurrence of sliding or offset during the clamping process, thereby achieving the effect of stable installation and adaptability to PVC tubes 28 of different sizes, and improving the flexibility and operational reliability of the device. The PVC tube 28 is open at one end and closed at the other end with a mesh. The aperture of the mesh is not greater than one-third of the distance between the eyes of the octopus larvae, which increases the exchange of water in the tube. As the breeding progresses, PVC tubes 28 of different diameters should be appropriately replaced according to the situation of the octopus larvae, and the number of PVC tubes 28 should be appropriately increased or decreased. The diameter of the PVC tube 28 is 1.2 to 1.8 times the distance between the eyes of the octopus larvae, and the length is set between 100 mm + 2 × the body length of the octopus larvae (in mm) and 100 mm + 4 × the body length of the octopus larvae. The PVC tube 28 is placed linearly on the support plate 14, with the open end adjacent to the closed end, and the placement spacing is set between 200 mm + 2 × the body length of the octopus larvae (in mm) and 200 mm + 3 × the body length of the octopus larvae. During the breeding process, the number of PVC tubes 28 placed is usually 1.2 to 1.5 times the number of octopus larvae to be cultured.
