Description

Technical Field

[0001] This utility model relates to the technical field of fish fry breeding and cultivation equipment, specifically to an isolation net cage for fish fry breeding and cultivation. Background Technology

[0002] The booming development of aquaculture has placed higher demands on the efficiency and quality of fish fry breeding. Traditional open-style fish fry rearing methods are easily affected by external environmental interference, leading to problems such as fry escape, predator infestation, and species mixing, making it difficult to guarantee the survival rate and quality of fry. With technological advancements, new rearing facilities such as modular rearing ponds and factory-style recirculating aquaculture systems have emerged. These facilities significantly improve rearing results through precise water quality control and environmental management, but they still have limitations in terms of flexible zoning and convenient management. Against this backdrop, isolation net cages for fish fry breeding have stood out with their unique advantages. They physically isolate fry of different species, sizes, or growth stages, effectively preventing them from fighting, competing for food, and spreading diseases. At the same time, the structural design of the net cages facilitates observation and management, allowing farmers to flexibly adjust stocking density and environmental conditions according to the growth of the fry. These isolation net cages have become a key link between traditional aquaculture and modern facilities, opening up a more efficient and scientific new path for fish fry breeding.

[0003] Existing isolation net cages used for fish fry breeding and cultivation require replacement when the isolation nets become damaged after long-term use. This necessitates workers carefully scooping the fish fry from the cage into a temporary holding tank using a net, then cutting the straps or ropes connecting the old net to the cage frame. The new isolation net is then laid flat on top of the cage frame, its position adjusted to ensure the net opening aligns with the frame opening, and the edges of the net are securely tied to the frame point by point with new straps or ropes. This method of replacing isolation nets is cumbersome, time-consuming, and highly dependent on manual labor. Therefore, we propose a new isolation net cage for fish fry breeding and cultivation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an isolation net cage for fish fry breeding and cultivation, which greatly shortens the replacement time of the isolation net, improves the efficiency of operation, reduces the dependence on manual labor, and shortens the idle time of the net cage, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an isolation net box for fish fry breeding and cultivation, comprising a frame, wherein grooves are provided on the upper side of the crossbeams of the frame, and pressure plates are provided inside the grooves, and an isolation net is provided between two adjacent upper and lower crossbeams of the frame, wherein the edges of the upper and lower ends of the isolation net are located between the lower surface of the pressure plate on the same side and the upper surface of the groove, and further comprising a quick fixing mechanism.

[0006] The quick-fixing mechanism includes rectangular slots, partitions, and insert rods. Rectangular slots are formed inside the pressure plates, and partitions are fixedly connected inside each slot. Insert rods are slidably connected inside each partition. Two short sidewalls of the pressure plates away from their center have clearance slots corresponding to the insert rods. The outside of each insert rod is slidably connected to the inside of the adjacent clearance slot on the same side. Insert holes are formed on the upper and lower ends of the vertical beams of the frame, on the sides that fit against the pressure plates. Insert rods are installed by engaging these adjacent insertion holes on the same side. This significantly shortens the replacement time of the isolation net, improves work efficiency, reduces reliance on manual labor, and reduces the idle time of the net cages.

[0007] Furthermore, the quick-fixing mechanism also includes a limiting plate and a spring. The limiting plate is fixedly sleeved on the outside of the insertion rod. The outside of the limiting plate is slidably connected to the inner wall of the rectangular groove. The spring is movably sleeved on the outside of the insertion rod. The insertion rod is located between the limiting plate and the adjacent partition located in the same rectangular groove, so as to realize the sliding rod is tightened.

[0008] Furthermore, the quick-fixing mechanism also includes a rack plate, a rotating column, and gears. The end of the insertion rod near the center of the rectangular groove is fixedly connected to a rack plate. A rotating column is rotatably connected between the two long side walls of the rectangular groove. Gears are fixedly sleeved on the outside of the rotating column. The gears are meshed with two rack plates located inside the same rectangular groove to realize synchronous movement of the sliding rod.

[0009] Furthermore, the quick-fixing mechanism also includes knobs. A knob is fixedly connected to one end of the rotating column that extends out of the pressure plate. The knobs are provided with evenly distributed anti-slip grooves on their outer surfaces to facilitate synchronous driving.

[0010] Furthermore, the upper surface of the groove is provided with rib grooves, and the bottom end of the pressure plate is provided with ribs. The ribs are all installed in conjunction with the rib grooves on the same side and vertically adjacent to each other to achieve physical fixation of the isolation net.

[0011] Furthermore, the top of the frame is provided with evenly distributed N-shaped frames, and foam floats are movably fitted on the outside of the crossbeams of the N-shaped frames to enable the cage to float.

[0012] Furthermore, the bottom of the frame is also equipped with an isolation net. The four edges of the isolation net at the bottom are located between the lower surfaces of the four pressure plates at the bottom and the upper surfaces of the four grooves at the bottom, thereby achieving isolation and interception at the bottom of the cage.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This isolation net cage for fish fry breeding and cultivation has the following advantages:

[0014] The rotating column is driven by a knob. The rack plates on both sides of the gear on the rotating column retract towards the center of the rectangular groove, thereby driving the insertion rod to exit from the insertion hole in the vertical beam of the frame. During this process, the spring is compressed and stores energy. When the insertion rod is completely disengaged from the insertion hole, the pressure plate and the frame are unlocked, and the isolation net can be easily lifted up for replacement. Then, the knob is turned clockwise, and the insertion rod extends. The spring releases potential energy and pushes the limiting plate to press against the groove wall, so that the insertion rod is accurately inserted into the insertion hole. The continuous elastic force of the spring firmly fixes the pressure plate to the frame, evenly pressing the edge of the isolation net, realizing the rapid replacement of the isolation net after the isolation net box is damaged. When removing the old net, there is no need to use other tools to cut the binding ropes one by one, which greatly shortens the replacement time, improves work efficiency, and reduces manual labor intensity. Compared with the traditional method, it effectively avoids the escape of fish fry and damage to the net due to uneven force, and improves the reliability of isolation. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4This embodiment provides a technical solution: an isolation net cage for fish fry breeding and cultivation, including a frame 1. Grooves 2 are provided on the upper sides of the crossbeams of the frame 1. Pressure plates 3 are provided inside the grooves 2. Isolation nets 4 are provided between two adjacent upper and lower crossbeams of the frame 1. The edges of the upper and lower ends of the isolation nets 4 are located between the lower surface of the pressure plate 3 and the upper surface of the groove 2 on the same side. It also includes a quick-fixing mechanism 6. Ribs 7 are provided on the upper surface of the grooves 2. Ribs 8 are provided at the bottom of the pressure plates 3. The ribs 8 are installed in conjunction with the vertically adjacent ribs 7 on the same side. N-shaped frames 9 are evenly distributed on the outer top of the frame 1. Foam floats 10 are movably fitted on the outside of the crossbeams of frame 9. An isolation net 4 is also provided at the bottom of frame 1. The four edges of the isolation net 4 at the bottom are located between the lower surface of the four pressure plates 3 at the bottom and the upper surface of the four grooves 2 at the bottom. The bottom ribs 8 are separated from the rib grooves 7 of the grooves 2, so the old isolation net 4 can be removed and the new isolation net 4 can be laid flat on the frame of frame 1. Ensure that the upper and lower edges of the net are accurately embedded in the grooves 2 of the crossbeam. At this time, the limiting function of the grooves 2 can initially fix the position of the net. Press down the pressure plate 3 so that the bottom ribs 8 are inserted into the rib grooves 7 to form a "convex and concave interlocking" structure. The edges of the isolation net 4 are initially fixed by physical interlocking.

[0022] Quick-fixing mechanism 6: It includes a rectangular groove 61, a partition 62, and a plug rod 63. The pressure plate 3 has a rectangular groove 61 inside, and a partition 62 is fixedly connected inside each rectangular groove 61. A plug rod 63 is slidably connected inside each partition 62. The two short sidewalls of the pressure plate 3 away from its center each have clearance grooves corresponding to the plug rod 63. The outside of each plug rod 63 is slidably connected to the inside of the clearance groove on the same side and adjacent to it. The upper and lower ends of the vertical beam of the frame 1 have insertion holes 5 on the sides that fit against the pressure plate 3. Each plug rod 63 is installed by fitting into the insertion hole 5 on the same side and adjacent to it. The quick-fixing mechanism 6 also includes a limiting plate 64 and a spring 65. The outside of the plug rod 63... Each limiting plate 64 is fixedly sleeved, and the outer side of the limiting plate 64 is slidably connected to the inner wall of the rectangular groove 61. Springs 65 are movably sleeved on the outer side of each insert rod 63. Each insert rod 63 is located between the limiting plate 64 and adjacent partition plates 62 located in the same rectangular groove 61. The quick-fixing mechanism 6 also includes a rack plate 66, a rotating column 67, and gears 68. A rack plate 66 is fixedly connected to the end of each insert rod 63 near the center of the rectangular groove 61. A rotating column 67 is rotatably connected between the two long side walls of the rectangular groove 61. Gears 68 are fixedly sleeved on the outer side of each rotating column 67, and each gear 68 meshes with two rack plates 66 located inside the same rectangular groove 61. Next, the quick-fixing mechanism 6 also includes knobs 69. A knob 69 is fixedly connected to one end of the rotating column 67 extending beyond the pressure plate 3. The knobs 69 have evenly distributed anti-slip grooves on their outer surfaces. When the isolation net in the fish fry breeding and cultivation isolation net box needs to be replaced after long-term use, rotating the knob 69 counterclockwise increases the operating friction due to the external anti-slip grooves, causing the rotating column 67 to rotate synchronously. The gear 68 on the rotating column 67 rotates accordingly, and through meshing transmission, the rack plates 66 on both sides retract towards the center of the rectangular groove 61. The rack plates 66 drive the insertion rod 63 to exit from the insertion hole 5 of the vertical beam of the frame 1. At this time, the spring 65 is compressed and stores energy due to the retraction of the insertion rod 63, and the limiting plate... 64 slides synchronously within the rectangular groove 61, providing guidance for subsequent reset. After the insertion rod 63 is completely disengaged from the insertion hole 5, the pressure plate 3 is unlocked from the frame 1. Lift the pressure plate 3 upwards and turn the knob 69 clockwise. The gear 68 drives the rack plate 66 to move to both sides again. The insertion rod 63 extends out of the clearance groove on the side wall of the pressure plate 3 along with the rack plate 66. The spring 65 releases the compressive potential energy and pushes the limiting plate 64 to press against the inner wall of the rectangular groove 61, so that the insertion rod 63 is accurately inserted into the insertion hole 5 of the vertical beam of the frame 1. At this time, the elastic force of the spring 65 is converted into a continuous fastening force, ensuring that the pressure plate 3 is tightly connected to the frame 1. The edge of the isolation net 4 is evenly pressed to avoid the fish fry escaping or the net being damaged due to uneven force.

[0023] The working principle of the isolation net box for fish fry breeding and cultivation provided by this utility model is as follows: When the isolation net needs to be replaced after long-term use, turn the knob 69 counterclockwise. The external anti-slip groove increases the operating friction, driving the rotating column 67 to rotate synchronously. The gear 68 on the rotating column 67 rotates accordingly. Through meshing transmission, the rack plates 66 on both sides retract towards the center of the rectangular groove 61. The rack plates 66 drive the insertion rod 63 to exit from the insertion hole 5 of the vertical beam of the frame 1. At this time, the spring 65 is compressed and stored due to the retraction of the insertion rod 63. The limiting plate 64 slides synchronously in the rectangular groove 61, providing guidance for subsequent reset. After the insertion rod 63 is completely disengaged from the insertion hole 5, the pressure plate 3 is unlocked from the frame 1. Lift the pressure plate 3 upward, and its bottom rib 8 separates from the rib groove 7 of the groove 2, so that the old isolation net 4 can be removed. Lay the new isolation net 4 flat on the frame of the frame 1, ensuring that the upper and lower edges of the net are accurately embedded in the grooves 2 of the crossbeam. At this time, the limiting effect of the grooves 2 can initially fix the position of the net. Press down the pressure plate 3 so that the bottom rib 8 is inserted into the rib groove 7, forming a "convex and concave interlocking" structure. The edge of the isolation net 4 is initially fixed by physical interlocking. Turn the knob 69 clockwise, and the gear 68 drives the rack plate 66 to move to both sides again. The insertion rod 63 extends out of the clearance groove on the side wall of the pressure plate 3 along with the rack plate 66. The spring 65 releases the compressive potential energy and pushes the limiting plate 64 to press against the inner wall of the rectangular groove 61, so that the insertion rod 63 is accurately inserted into the insertion hole 5 of the vertical beam of the frame 1. At this time, the elastic force of the spring 65 is converted into a continuous tightening force, ensuring that the pressure plate 3 is tightly connected to the frame 1. The edge of the isolation net 4 is evenly pressed, avoiding the escape of fish fry or damage to the net due to uneven force.
