Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a breeding device for raising seafood seedlings. Background Art

[0002] Seafood aquaculture is a major global aquaculture industry, and the quality of seedlings directly impacts aquaculture efficiency and yield. Seedling cultivation is the first step in seafood aquaculture, and the key lies in providing a suitable growth environment and nutritional support for the temporary rearing and nurturing of seedlings until they reach suitable size for stocking.

[0003] Water quality is one of the key factors in seedling cultivation and has a direct impact on the growth and health of seafood seedlings.

[0004] To ensure the healthy growth of young seafood, existing aquaculture devices typically improve water quality through water changes, thereby ensuring healthy growth. However, during the aquaculture process, fish excrement and food residue often accumulate at the bottom of the device, making it difficult to clean by simply changing the water. Over time, dirt also accumulates on the sidewalls of the device, breeding bacteria and affecting the healthy growth of the young. To address these issues, we propose a seafood aquaculture device. Utility Model Content

[0005] The purpose of the utility model is to provide a breeding device for raising seafood seedlings, so as to solve the problem that the bottom and side walls of the breeding device are difficult to clean.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a breeding device for raising seafood seedlings, comprising a breeding box, wherein an impurity precipitation area and a breeding area are formed in the breeding box, an isolation mechanism for regulating the connection between the impurity precipitation area and the breeding area is provided between the impurity precipitation area and the breeding area, wherein a bottom cleaning mechanism is provided in the impurity precipitation area;

[0007] A seedling raising cage is provided in the breeding area, and a side cleaning mechanism for cleaning the side wall of the breeding cage is provided between the breeding cage and the seedling raising cage;

[0008] The side cleaning mechanism includes four lifting and flipping components, which are arranged at the four corners of the breeding box body, and a scraper is connected between each adjacent lifting and flipping component.

A slide is fixed to the inner wall of the breeding box in the circumference. The edges of the isolation plates slide in the slide. Strip channels are arranged on the two isolation plates, and the minimum distance between adjacent strip channels is greater than the minimum width of the strip channels.

[0010] According to the above technical solution, the outer wall of the breeding box is fixedly connected to the power box, and the side walls of the two isolation plates are fixedly connected to the moving rod. The end of the moving rod extending into the power box is provided with teeth, and the teeth on both sides are engaged with gears that are rotatably connected to the inner wall of the power box.

[0011] According to the above technical solution, evenly distributed scrapers are fixedly connected to the breeding box body, and the scrapers abut against the upper end surface of the isolation plate on the top layer.

[0012] According to the above technical solution, the lifting and flipping assembly includes a mounting column fixedly connected between the breeding box body and the seedling cage, the side wall of the mounting column is provided with a vertical guide groove and a vertical flipping guide groove, the side wall of the scraper is fixed with a first guide rod sliding in the vertical guide groove and a second guide rod sliding in the vertical flipping guide groove, and a driving member is provided on the mounting column, and the driving member is connected to the second guide rod through a connecting rod.

[0013] According to the above technical solution, a sliding block is fixed to one end of the first guide rod away from the scraper blade, and the sliding block is elliptical. The top of the vertical guide groove is provided with a rotating groove connected thereto, and the vertical flip guide groove includes a vertical guide groove and a flip guide groove connected to each other.

The output end of the electric cylinder passes through the breeding box and extends into the impurity precipitation area. The output end of the electric cylinder is hinged with a linear guide rail connected to the high-pressure water pipe.

[0017] According to the above technical solution, a mud collecting trough is fixedly connected to the outer edge of the breeding box.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model provides an isolation mechanism between the impurity precipitation zone and the aquaculture zone, allowing for flexible regulation of the connection between the two zones. When cleaning the impurity precipitation zone, it effectively prevents the marine life in the aquaculture zone from being affected. The two isolation plates of the isolation mechanism, when performing reverse reciprocating motion, are equipped with scrapers to scrape off dirt from the surfaces of the isolation plates. The scraped dirt is then pushed into the strip channel and falls into the impurity precipitation zone, ensuring that the isolation mechanism remains clean and further maintaining the water quality of the aquaculture tank.

[0034] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-11 The present invention provides a technical solution for aquaculture equipment for raising seafood seedlings, comprising a breeding tank 1, wherein an impurity settling area 2 and a breeding area 3 are formed in the breeding tank 1. The breeding area 3 is used for breeding seafood, and the impurity settling area 2 is used to precipitate impurities in the water of the breeding tank 1 (such as excrement of the fry and food residues). Impurities in the water (such as excrement of the fry and food residues) will fall into the impurity settling area 2.

[0036] An isolation mechanism 4 is provided between the impurity precipitation area 2 and the breeding area 3 for regulating the flow between the impurity precipitation area 2 and the breeding area 3, wherein a bottom cleaning mechanism 5 is provided in the impurity precipitation area 2, and the bottom cleaning mechanism 5 can clean the bottom of the impurity precipitation area 2. After long-term breeding, impurities in the water body (such as fish fry excrement and food residues) will settle and fall into the impurity precipitation area 2. The isolation mechanism 4 can cut off the flow between the impurity precipitation area 2 and the breeding area 3, and then the bottom of the impurity precipitation area 2 can be cleaned by the bottom cleaning mechanism 5 to prevent the fish fry excrement and food residues from accumulating at the bottom and breeding bacteria, thereby ensuring the cleanliness of the seedling environment. In addition, with the isolation of the isolation mechanism 4, the marine organisms in the breeding area 3 will not be affected during cleaning.

[0037] Aquaculture area 3 is equipped with a nursery cage 6. A side cleaning mechanism 7 is installed between the cage 1 and the cage 6 to clean the side walls of the cage 1. The cage 6 isolates the marine life from the side cleaning mechanism 7. The side cleaning mechanism 7 includes a lifting and flipping assembly 71 located at the four corners of the cage 1. A scraper 72 is connected between each adjacent lifting and flipping assembly 71. The scraper 72, activated by the lifting and flipping assembly 71, cleans the side walls of the cage 1, removing dirt and tilting the cage 1 outwards to prevent bacterial growth and provide a favorable growth environment for the young seafood.

[0038] Specifically, the isolation mechanism 4 includes two isolation plates 41 that reciprocate in opposite directions. A slideway 42 is fixedly connected to the inner wall of the breeding box 1 in the circumferential direction. The edges of the isolation plates 41 slide in the slideway 42. Strip channels are arranged on both isolation plates 41. The minimum distance between adjacent strip channels is greater than the minimum width of the strip channels.

[0039] Specifically, the isolation mechanism 4 includes two isolation plates 41 that reciprocate in opposite directions. A slide 42 is fixedly connected to the inner wall of the breeding box 1 in the circumferential direction. The edges of the isolation plates 41 slide in the slide 42, so that the isolation plates 41 can move smoothly in the slide, and flexible adjustment of the on-off between the impurity precipitation area 2 and the breeding area 3 is achieved. Strip channels are arranged on the two isolation plates 41, and the minimum distance between adjacent strip channels is greater than the minimum width of the strip channels. In the process of the two isolation plates 41 sliding along the slide 42, the upper isolation plate 41 will scrape off the dirt on the surface of the lower isolation plate 41, and through the reverse reciprocating motion of the two isolation plates 41, the scraped dirt is pushed into the strip channels and falls into the impurity precipitation area 2, thereby cleaning the dirt on the surface of the isolation plates 41.

[0040] Under normal conditions, i.e., when the impurity precipitation zone 2 is not being cleaned, the strip-shaped channels on the upper and lower isolation plates 41 are in one-to-one correspondence (one-to-one communication). When the impurity precipitation zone 2 and the breeding zone 3 need to be disconnected, the two isolation plates 41 are slid relative to each other, causing the strip-shaped channels on the upper and lower isolation plates 41 to be staggered one by one, thus disconnecting the impurity precipitation zone 2 and the breeding zone 3, and cleaning the impurity precipitation zone 2 can be performed.

[0041] Specifically, the outer wall of the breeding box 1 is fixedly connected to a power box 8, which provides power support for the movement of the isolation plate. The side walls of the two isolation plates 41 are fixedly connected to moving rods 43. The ends of these moving rods 43 extend to the interior of the power box 8. The moving rods 43 inside the power box 8 are partially provided with teeth. In the internal space of the power box 8, there is a gear 44 rotatably connected to the inner wall of the power box 8, which is engaged between the teeth on both sides. It is driven by an external motor to rotate and interacts with the teeth on the moving rod 43 to achieve precise control of the movement of the isolation plate 41.

[0042] When the gear 44 rotates, it drives the movable rods 43 on both sides to move, thereby enabling the two isolation plates 41 to reciprocate in opposite directions. This design not only ensures the accuracy and stability of the movement of the isolation plates 41, but also allows for flexible adjustment of the on-off state between the impurity precipitation area 2 and the breeding area 3 according to actual needs.

[0043] At the same time, the meshing of gear 44 and the teeth effectively transmits power, making the movement of isolation plate 41 smoother and more efficient. Whether maintaining the one-to-one connection of the strip channels under normal conditions or staggering the strip channels when disconnecting the impurity precipitation area 2 and the aquaculture area 3, this power system can reliably complete the task, providing a strong guarantee for the normal operation of the aquaculture device for seafood seedlings.

[0044] Specifically, evenly distributed scrapers 45 are fixed in the breeding box 1, and the scrapers 45 abut against the upper end surface of the isolation plate 41 on the top layer;

[0045] Specifically, evenly distributed scrapers 45 are firmly connected to the inside of the breeding box 1. These scrapers 45 are fixed to the slide 42. The scrapers 45 are in close contact with the upper end surface of the top isolation plate 41, and can effectively clean the upper end surface of the top isolation plate 41 during the movement of the isolation plate 41.

[0046] When the isolation plate 41 performs reverse reciprocating motion in the slide 42, the scraper 45 can scrape off the dirt, impurities and other residues accumulated on the upper end surface of the top isolation plate 41. Similarly, under the reverse reciprocating motion of the two isolation plates 41, the scraped dirt is pushed into the strip channel and falls into the impurity precipitation area 2, further realizing the cleaning of the dirt on the surface of the isolation mechanism 4.

[0047] This design ensures that the isolation mechanism 4 always remains relatively clean, avoiding the accumulation of dirt that may affect the water quality of the water in the aquaculture box 1. At the same time, the close cooperation between the scraper and the isolation plate 41 provides a better environmental condition for the healthy aquaculture of seafood.

[0048] Specifically, the lifting and flipping assembly 71 includes a mounting post 711 fixed between the breeding box 1 and the seedling cage 6, and the mounting post 711 is fixed to the slide 42 of the isolation mechanism 4. The side wall of the mounting post 711 is provided with a vertical guide groove 712 and a vertical flip guide groove 713. The side wall of the scraper 72 is fixed with a first guide rod 714 sliding in the vertical guide groove 712 and a second guide rod 715 sliding in the vertical flip guide groove 713. The mounting post 711 is provided with a cavity, and the driving member is installed in the cavity. The driving member can be an optional cylinder, and the driving member is connected to the second guide rod 715 via a connecting rod 716. This ingenious design enables the scraper 72 to perform accurate vertical movement and flipping along the side wall of the mounting post 711 under the action of the driving member, thereby achieving efficient cleaning of the side wall of the breeding box 1 and smooth discharge of dirt.

[0049] Specifically, a sliding block 717 is fixedly connected to one end of the first guide rod 714 away from the scraper 72, and a rotating groove 718 is provided at the top of the vertical guide groove 712 in communication with it. When the scraper 72 is turned over to discharge sewage under the cooperation of the second guide rod 715 and the vertical flip guide groove 713, the sliding block 717 can rotate in the rotating groove 718. The sliding block 717 is elliptical, and the short axis of the ellipse is smaller than the width of the vertical guide groove 712, so that the sliding block 717 can slide up and down in the vertical guide groove 712, and the long axis of the ellipse is larger than the width of the vertical guide groove 712, so that after the second guide rod 715 drives the scraper 72 to turn over, the sliding block 717 cannot Entering the vertical guide groove 712, and in the process of the driving member driving the second guide rod 715 and the scraper 72 to move downward, the first guide rod 714, with the cooperation of the sliding block 717 and the entrance of the vertical guide groove 712, the sliding block 717 will not enter the vertical guide groove 712 first, but the second guide rod 715 will first drive the scraper 72 to flip and then make the sliding block 717 rotate in the rotating groove 718 until the short axis of the elliptical sliding block 717 is perpendicular to the vertical axis of the vertical guide groove 712. The elliptical sliding block 717 will enter the vertical guide groove 712 and move downward with the second guide rod 715 and the scraper 72.

[0050] The vertical flip guide groove 713 includes a vertical guide groove and a flip guide groove that are interconnected. The vertical guide groove is parallel to the vertical guide groove 712 and can limit the vertical movement trajectory of the second guide rod 715. The flip guide groove can guide the second guide rod 715, thereby limiting the flipping trajectory of the scraper 72.

[0051] This structure allows the scraper 72 to smoothly transition from vertical movement (scraping dirt from the side walls of the aquaculture tank 1) to rotational movement (discharging the scraped dirt from the aquaculture tank 1), ensuring a smooth and efficient cleaning process. This carefully designed guide structure provides reliable cleaning of the side walls of the aquaculture tank 1, further improving the overall performance and practicality of the aquaculture device for seafood seedling cultivation.

[0052] Specifically, one end of the connecting rod 716 is hinged with an articulated rod 719, and the articulated rod 719 is articulated with the second guide rod 715. This hinged connection method allows the connecting rod 716 to more flexibly transmit the power of the driving member, so that the second guide rod 715 can obtain accurate driving force in different stages of movement. When the driving member is working, the connecting rod 716 is connected to the second guide rod 715 through the articulated rod 719, which can effectively transmit power to the second guide rod 715, thereby driving the scraper 72 to perform vertical movement or flip movement. This connection method not only improves the efficiency of power transmission, but also increases the flexibility and reliability of the entire side cleaning mechanism 7, providing a more stable and efficient solution for cleaning the side walls of the breeding box 1.

[0053] The side wall of the high-pressure water pipe 51 is connected to the high-pressure nozzle 52. An angle adjustment member connected to the high-pressure water pipe 51 is provided on the breeding box 1. This angle adjustment member can flexibly adjust the angle of the high-pressure water pipe 51, so that the high-pressure nozzle 52 can be aimed at different positions of the impurity precipitation area 2 for high-pressure flushing. When it is necessary to clean the bottom of the impurity precipitation area 2, the high-pressure water pipe 51 sprays high-pressure water through the high-pressure nozzle 52. The powerful impact force can effectively flush out impurities such as fish fry excrement and food residues deposited at the bottom. The hinged design allows the high-pressure water pipe 51 to rotate freely within a certain range. In conjunction with the angle adjustment member, it can clean every corner of the impurity precipitation area 2 more accurately, ensuring the cleaning effect of the bottom. This design not only improves the cleaning efficiency, but also provides a cleaner breeding environment for seafood seedlings, effectively ensuring the healthy growth of seafood seedlings.

[0054] Specifically, the angle adjustment member includes an electric cylinder 531 fixed to the outer wall of the breeding box 1. The output end of the electric cylinder 531 passes through the breeding box 1 and extends into the impurity precipitation area 2. The output end of the electric cylinder 531 is hinged with a linear guide rail 532 connected to the high-pressure water pipe 51.

[0055] Specifically, the angle adjustment component comprises an electric cylinder 531 fixed to the outer wall of the aquaculture tank 1. The output end of the electric cylinder 531 extends through the aquaculture tank 1 and into the impurity settling area 2. A linear guide 532 is fixed to the high-pressure water pipe 51. The output end of the electric cylinder 531 is hingedly connected to the slide of the linear guide 532. The electric cylinder 531 can precisely control the extension and retraction length and speed of the output end, thereby adjusting the angle of the high-pressure water pipe 51 through the hinged linear guide 532.

[0056] When the angle of the high-pressure water pipe 51 needs to be changed, the electric cylinder 531 is activated, and the output end extends or retracts, driving the slide of the linear guide 532 to move. Because the linear guide 532 is connected to the high-pressure water pipe 51, and the slide is hinged to the output end of the electric cylinder 531, the extension and retraction of the output end of the electric cylinder 531 causes the high-pressure water pipe 51 to rotate about its hinge point with the inner wall of the breeding tank 1, thereby adjusting the angle of the high-pressure water pipe 51.

[0057] Specifically, a mud trough 9 is fixedly attached to the outer edge of the aquaculture box 1 to collect dirt and impurities discharged from the aquaculture box 1. When the scraper blades 72 in the side cleaning mechanism 7 scrape dirt from the side walls of the aquaculture box 1 and turn it over for discharge, and when the bottom cleaning mechanism 5 cleans the impurity settling area 2, the discharged dirt and impurities fall into the mud trough 9. The mud trough 9 can be cleaned regularly to prevent the accumulation of dirt and impurities, which could affect the aquaculture environment.
