Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, specifically a device for raising octopus larvae. Background Technology

[0002] In traditional octopus larvae farming, PVC pipes of any number and diameter are typically used as shelters. These pipes often roll along the bottom of the cement tank with the water flow, causing the larvae to be startled and escape, resulting in ink spraying stress. Simultaneously, the rolling PVC pipes cause squeezing and abrasions to the larvae, leading to injury and death. Too many PVC pipes obstruct water flow when cleaning the cement tank, making cleaning difficult; too few PVC pipes cause larvae to compete for shelter, resulting in physical loss and energy depletion, leading to farming losses. Multiple larvae entering the PVC pipe from both ends fight inside, causing injury and death. Furthermore, a single layer of shelter at the bottom of the tank does not fully utilize the farming space. Therefore, traditional farming methods lack consideration for the specific behavioral habits of octopus larvae, and the structural instability affects their growth, failing to provide adequate hiding and shelter, resulting in losses in octopus farming. Providing a stable breeding facility is one of the important requirements for octopus larvae farming. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device and method for raising octopus larvae, which solves the problems of instability and low efficiency in current octopus larvae raising devices.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a juvenile octopus breeding device, including a shell, the shell being a frame structure, with a limiting post fixedly connected to each of the four corners of the shell, and multiple partitions being horizontally slidably installed on the limiting posts, with an adjustment component between the partitions for adjusting the distance between adjacent partitions, and a breeding mechanism being provided on each partition.

[0005] The partition is provided with connecting blocks at the four corners, the connecting blocks are slidably disposed with the limiting post, and a reset component is fitted on the limiting post between the upper and lower connecting blocks.

[0006] The adjustment assembly includes a fixed frame, a bidirectional threaded rod, and a connecting rod. The fixed frame is installed on both sides of the upper surface of the partition plate. The bidirectional threaded rod is horizontally installed on the fixed frame. Sleeves are symmetrically threaded 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 plate. One end of the bidirectional threaded rod is connected to a drive assembly.

[0007] Furthermore, the multiple partitions, from bottom to top, include a first partition, a second partition, and a third partition. The drive assembly includes a waterproof motor, the outer wall of which is fixedly connected to the outer wall of the fixing frame, and the output end of the waterproof motor is connected to one end of a bidirectional threaded rod.

[0008] Furthermore, the reset assembly includes a first spring, which is sleeved inside the outer wall of a limiting post, and both ends of the first spring are fixedly connected between the connecting blocks.

[0009] Furthermore, the breeding structure includes support plates, with multiple support plates spaced apart on a partition. Each support plate has a groove on its side, and a connecting plate is slidably installed in the groove. A slider is provided on one side of the connecting plate, and the slider is installed in conjunction with the groove. A support rod is fixedly connected to the outer wall of the connecting plate.

[0010] Furthermore, a second limiting post is slidably connected inside the connecting plate, and a shaped rod is fixedly connected to one end of the second limiting post. A third spring is provided inside the connecting plate, with one end of the third spring fixedly connected to the other end of the second limiting post and the other end of the third spring fixedly connected inside the connecting plate.

[0013] This invention provides a device for raising octopus larvae. It has the following beneficial effects:

[0014] 1. This utility model uses a bidirectional threaded rod that moves along the outer wall of the bidirectional threaded rod via a sleeve. The sleeve, through a handle and connecting rod, drives the connecting rods on both sides to move in opposite directions or towards each other, thereby causing the first partition and the second partition to move closer or further apart. This achieves the effect of adjusting the spacing between each layer of partitions, thus adjusting the vertical living space of the octopus larvae. This, combined with the adjustment of the PVC pipes, completes the breeding process. At the same time, increasing the spacing between the partitions also facilitates the replacement of each layer of PVC pipes, improving the convenience of the octopus larvae breeding device.

At the same time, the ball inside the clamp fits against the outer wall of the PVC pipe and is supported by the tension of the second spring. It can adapt to PVC pipes of different sizes, thus solving the problem of inconvenient disassembly and installation when the octopus larvae need to be replaced with larger PVC pipes as they grow, and improving the practicality of the octopus larvae breeding device.

[0016] 3. This utility model allows for the sliding installation of connecting plates by setting grooves on the side of the support plate, thereby achieving the effect of adjusting the spacing and number of PVC pipes and thus adjusting the horizontal living space of the octopus larvae.

[0021] 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.

[0022] Please see the appendix Figure 1 -Appendix Figure 3This utility model embodiment provides a juvenile octopus breeding device. The shell (1) is a frame structure. Limiting posts (2) are fixedly connected to the four corners of the shell. Multiple partitions are horizontally slidably installed on the limiting posts. Adjustment components are provided between the partitions to adjust the distance between adjacent partitions. Each partition is provided with a breeding mechanism.

[0023] The partition is provided with connecting blocks (13) at the four corners. The connecting blocks are slidably disposed with the limiting post 1, and a reset component is fitted on the limiting post 1 between the upper and lower connecting blocks.

[0024] The adjustment assembly includes a fixed frame, a bidirectional threaded rod (8), and a connecting rod. The fixed frame is installed on both sides of the upper surface of the partition plate. The bidirectional threaded rod is horizontally installed on the fixed frame. A sleeve (10) is symmetrically threaded 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 plate. One end of the bidirectional threaded rod is connected to a drive assembly.

[0025] Specifically, a limiting post 2 is fixedly connected inside the shell 1 to provide sliding limit function for the first partition 3 and the second partition 4, ensuring the stability and adjustment accuracy of the partitions. The shell 1 contains the first partition 3 and the second partition 4, providing multi-layered habitat units to meet the breeding needs of octopus larvae. Limiting components are provided on the outer walls of both the first partition 3 and the second partition 4 to constrain the sliding position of the partitions, preventing tilting or positional displacement during adjustment. An adjustment component is provided between the first partition 3 and the second partition 4 to flexibly adjust the distance between the two partitions, facilitating adjustments to the breeding space according to the growth stage of the octopus larvae. A slot 29 is provided inside the shell 1 to provide water flow and maintain a suitable breeding environment. PVC pipes 28 are provided at the top of the first partition 3 and the second partition 4 as habitat units for the octopus larvae, facilitating their resting and living. A handle 5 is fixedly connected to the top of the shell 1.

[0026] The adjusting assembly includes a connecting rod 6, one end of which is rotatably connected to the bottom of the second partition 4. Force is transmitted through rotation, facilitating smooth adjustment of the partition. A sleeve 10 is rotatably connected to one end of the connecting rod 6. The sleeve 10 has internal threads and is fitted with a bidirectional threaded rod 8. The design of the bidirectional threaded rod 8 allows for linear movement of the sleeve 10, thereby driving the connecting rod 6 to support the partition and adjust the height of the second partition 4. The limiting assembly includes a connecting block 13, one side of which is fixedly connected to the outer walls of both the first partition 3 and the second partition 4. This secures the partition to the limiting post 2, ensuring smooth sliding of the partition during adjustment. Limiting blocks 7 and 11 are fixedly connected to the top of the first partition 3. These limiting blocks constrain the range of motion of the adjusting assembly, ensuring stability and safety during adjustment. A driving assembly is located on the outer wall of the limiting block 11, providing a power source for more efficient partition adjustment. Connecting block 13 is slidably connected to the outer wall of limiting post 2, providing an adjustable movement trajectory for the partition through sliding. A reset component is provided on the outer wall of limiting post 2. This reset component provides elastic support, allowing the partition to automatically return to its original position during adjustment, enhancing the convenience of the device. The drive component includes a waterproof motor 9, whose outer wall is fixedly connected to the outer wall of limiting block 11. It drives the rotation of the bidirectional threaded rod 8, enabling precise adjustment of the partition. The output end of the waterproof motor 9 is connected to one end of the bidirectional threaded rod 8, ensuring efficient power transmission. The reset component includes a first spring 12, which is internally sleeved on the outer wall of limiting post 2, providing necessary elastic support for the partition. Both ends of the first spring 12 are fixedly connected between connecting blocks 13. Through the elastic reset function, the partition can quickly return to its original position after adjustment, further improving the ease of operation of the device.

[0027] Specifically, when adjusting the distance 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. The rotation of the bidirectional threaded rod 8 causes the sleeve 10 to move linearly in opposite directions or in the same direction along the outer wall of the bidirectional threaded rod 8. The sleeve 10 transmits the motion through the connecting rod 6, causing the connecting rods 6 on both sides to move synchronously, thereby precisely adjusting the distance between the first partition 3 and the second partition 4. Furthermore, during the adjustment of the distance 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, allowing the device to adjust the partition spacing of each layer separately, flexibly meeting the needs of multi-layer structures. In addition, the first partition 3 and the second partition 4 are reliably limited on the outer wall of the limiting post 2 by the connecting block 13, effectively avoiding misalignment 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. Meanwhile, the tension of the first spring 12 provides a durable and reliable support for the second partition 4, ensuring that it moves smoothly during adjustment and avoiding shaking or tilting. This achieves the effect of flexibly adjusting the spacing between each partition, improving the adaptability and operational precision of the device. The device is made of waterproof and corrosion-resistant materials to enhance the durability of the aquaculture device in seawater. The spacing between the partitions can vary depending on the aquaculture period, and is set between 240mm + 4 × octopus larvae body length (in mm) and 240mm + 6 × octopus larvae body length.

[0028] The aquaculture mechanism includes a support plate 14. Multiple support plates 14 are detachably mounted on the top of the first partition 3. A groove 30 is formed on the upper side of each support plate 14, within which a connecting plate 15 is slidably mounted. A slider 31 is formed on one side of each connecting plate, which is installed in conjunction with the groove. The support plates provide a stable mounting foundation for the connecting plate 15 and related components, ensuring sufficient support strength during use. A support rod 19 is fixedly connected to the outer wall of the connecting plate 15. The support rod 19 provides a support point for the rotation of the connecting rod 21, ensuring the smooth operation of the device. A limiting post 16 is slidably connected inside the connecting plate 15. The limiting post 16 allows the irregularly shaped rod 17 to be flexibly adjusted in position to adapt to different operational needs. One end of the limiting post 16 is fixedly connected to the irregularly shaped rod 17, which serves as the core component of the adjustment and clamping structure, transmitting the adjustment force of the device. A third spring 27 is installed inside the connecting plate 15. One end of the third spring 27 is fixedly connected to the other end of the limiting post 16. The third spring 27 provides elastic support, allowing the limiting post 16 to quickly reset after the force is released, improving the convenience and stability of operation. The other end of the third spring 27 is fixedly connected inside the connecting plate 15. Through the elastic action of the spring, the reset efficiency of the irregular rod 17 is enhanced. A guide groove 18 is provided inside the irregular rod 17, which provides a trajectory for the sliding of the guide post 26, thereby ensuring the directional stability of the guide post 26 during movement. A guide post 26 is installed inside the irregular rod 17 and is slidably connected inside the guide groove 18. The sliding fit allows for flexible adjustment of the irregular rod 17 and further improves the working efficiency of the device. A connecting rod 21 is fixedly connected to one end of the guide post 26. The connecting rod 21, as a connecting component, transmits the movement of the guide post 26 to the clamping plate 22 through its rotation function. A pivot 20 is rotatably connected inside the connecting rod 3 21. One end of the pivot 20 is fixedly connected inside the support rod 19, providing a fulcrum for the rotation of the connecting rod 3 21, thus ensuring smooth motion transmission. The other end of the connecting rod 3 21 is fixedly connected to a pivot 25. A clamping plate 22 is rotatably connected to the outer wall of the pivot 25. The clamping plate 22 can rotate flexibly through the connection of the pivot 25 and provides reliable support for clamping the PVC pipe 28. A ball 24 is slidably connected inside the clamping plate 22. The ball 24 fits against the outer wall of the PVC pipe 28, and its mobility adapts to the surface of pipes of different sizes, improving the applicability of the device. A second spring 23 is provided inside the clamping plate 22. One end of the second spring 23 is fixedly connected inside the clamping plate 22. The second spring 23 provides tension support, keeping the ball 24 in contact with the PVC pipe 28 at all times. The other end of the second spring 23 is fixedly connected to the outer wall of the ball 24. The clamping effect is further enhanced by the spring force, thereby ensuring the fixed reliability of the PVC pipe 28 and improving the device's ability to adapt to pipes of different sizes.

[0029] Specifically, when clamping and installing the PVC pipe 28, the operation is simple and convenient; simply insert the shaped rod 17 into the device. The shaped rod 17 is precisely positioned on the inner wall of the connecting plate 15 by the limiting post 2 16, while simultaneously compressing and storing energy in the third spring 27 during insertion. Next, the shaped rod 17 slides along the guide post 26 within the guide groove 18. The guide post 26 rotates around the rotating shaft 20 via the movement of the connecting rod 3 21. The other end of the rotating shaft 20, through linkage with the rotating shaft 25, drives the clamping plate 22 to gradually retract, achieving a stable clamping of the PVC pipe 28. When the shaped rod 17 is released, the restoring force of the third spring 27 causes the shaped rod 17 to return to its original position, and the clamping plate 22 automatically adjusts to a fixed position, thus firmly fixing the PVC pipe 28. One end of the PVC pipe 28 is sealed, while the other end allows the insertion of octopus larvae. Simultaneously, the clamping plate 22 contains a sphere 24 that fits snugly against the outer wall of the PVC pipe 28. Supported by the continuous tension provided by the second spring 23, the clamping plate 22 can flexibly adapt to PVC pipes 28 of different diameters. This structural design not only enhances the device's adaptability to various specifications of PVC pipes 28 but also effectively prevents slippage or displacement during clamping, achieving stable installation and adaptability to different sizes of PVC pipes 28, thus improving the device's flexibility and operational reliability. The PVC pipe 28 is open at one end and closed at the other with a mesh. The mesh aperture is no larger than one-third of the interocular distance of the octopus larvae, increasing water exchange within the pipe. As the farming progresses, PVC pipes 28 of different diameters should be replaced as needed, and the number of PVC pipes 28 should be increased or decreased accordingly, depending on the condition of the larvae. The diameter of the PVC pipe 28 is 1.2 to 1.8 times the interocular distance of the octopus larvae, and its length is set between 100mm + 2 × octopus larvae body length (in mm) and 100mm + 4 × octopus larvae body length. The PVC pipes 28 are arranged linearly on the support plate 14, with the open and closed ends adjacent to each other, and the spacing between them is set between 200mm + 2 × octopus larvae body length (in mm) and 200mm + 3 × octopus larvae body length. During the rearing process, the number of PVC pipes 28 used is typically 1.2 to 1.5 times the number of reared octopus larvae.
