Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to a high-strength cage. Background Technology

[0002] A high-strength net cage is a large-scale piece of equipment used in aquaculture for the large-scale cultivation of fish and shellfish in marine and lake environments. Its core feature is that through optimized structural design and the selection of high-strength materials, it has the ability to resist strong winds, waves, water currents, and long-term underwater environmental erosion. It is widely used in complex waters of deep sea and nearshore areas and is a key facility for achieving high-density and high-efficiency aquaculture. This type of net cage is usually composed of a load-bearing frame, high-strength netting, mooring system, and auxiliary functional components. The whole cage must meet multiple requirements for structural stability, deformation resistance, and aquaculture safety, providing a suitable growth space for aquatic organisms.

[0003] Early net cages consisted of wooden frames or ordinary metal supports with nylon netting, which could only be used in shallow waters or areas with gentle waves. They suffered from problems such as easily corroded frames and insufficient netting strength. When faced with stronger currents or seasonal waves, the frames often broke and the netting tore, leading to the escape of aquaculture organisms. Furthermore, they had a short lifespan and high maintenance costs. To address these issues, current high-strength net cages generally use stainless steel, high-strength alloys, or composite materials for the frames, paired with UV-resistant and wear-resistant composite netting. The overall stability is enhanced through truss supports and frustum-shaped structures, while mooring systems are introduced to improve wave resistance, significantly improving the structural strength and lifespan of the net cages. However, existing net cages still face the problem of large-scale attachment of marine organisms during long-term aquaculture. Because the net cages are submerged in water for extended periods, the connection between the netting surface and the frame becomes an ideal habitat for these organisms. These organisms attach themselves to the netting surface by secreting mucus or byssal threads. As the amount of attachment increases, it not only increases the overall weight of the net cage, increasing the load on the mooring system and the energy consumption of the lifting device, but also clogs the netting pores, hindering water exchange and affecting the stability of the aquaculture environment. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the waves beat against the net cage, the connecting rope swings with the waves, causing the arc-shaped beating plate to impact the pressure-resistant net cage. At the same time, the striking column inside the cylinder undergoes inertial displacement due to the swaying of the waves, impacting the inner wall of the cylinder and generating high-frequency vibrations. These vibrations are transmitted to the surface of the net cage through the arc-shaped beating plate, disrupting the adhesion of marine organisms and causing them to detach. The buoyancy ring provides buoyancy for the cleaning mechanism, ensuring the effective operation of the beating plate. The limiting ring constrains the swaying amplitude of the pressure-resistant net cage, preventing violent collisions with the pedal ring, thereby cleaning the organisms attached to its surface.

[0023] 2. In this utility model, by pouring feed into the feeding cylinder, the feeding cylinder is suspended above the top of the conical interception net by the buoyancy of the air bladder ring, and its position can be adjusted by sliding along the inner wall of the interception net. When water flows into the feeding cylinder, it impacts the propeller blades and drives the rotating column to rotate, which in turn drives the L-shaped push plate to rotate synchronously. The rotating push plate throws the feed evenly to all sides. Then, through the guidance of the conical interception net, the feed is dispersed and falls into the pressure-resistant net box, realizing automated and uniform feeding. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a high-strength wire mesh cage, including a foot plate ring 1 and a pressure-resistant wire mesh cage 4. A cleaning mechanism 2 is provided at the bottom of the inner wall of the foot plate ring 1. A conical intercepting net 5 is fixedly connected to the top of the pressure-resistant wire mesh cage 4. A material dispersing mechanism 3 is provided at the top of the inner wall of the conical intercepting net 5. A fixing component 6 is provided on the outer wall of the foot plate ring 1. An anti-slip component 8 is provided at the top of the foot plate ring 1.

[0034] The cleaning mechanism 2 includes multiple connecting ropes 201, the top ends of which are fixedly connected to the bottom of the inner wall of the pedal ring 1. Multiple arc-shaped striking plates 202 are fixedly connected to the outer walls of the connecting ropes 201. The connecting ropes 201 at the bottom of the inner wall of the pedal ring 1 oscillate with the waves, causing the arc-shaped striking plates 202 to impact the outer wall of the pressure-resistant gabion 4. The special shape design of the arc-shaped striking plates 202 allows them to conform to the curved surface of the gabion, enhancing the striking effect. Multiple cylinders 203 are fixedly connected to the inner wall of the arc-shaped striking plates 202, and striking posts 204 are fixedly connected to the inner wall of the cylinders 203. Inside the cylinders 203... The striking column 204 generates inertial displacement under the swaying of the waves, repeatedly impacting the inner wall of the cylinder 203, forming high-frequency vibration. This mechanical vibration is transmitted to the surface of the net cage through the arc-shaped striking plate 202, effectively destroying the adhesion of marine attached organisms and causing them to fall off. The top of the pedal ring 1 is fixedly connected to a buoyancy ring 205, and the outer wall of the pressure-resistant net cage 4 is fixedly connected to multiple limiting rings 206. The limiting rings 206 constrain the swaying amplitude of the pressure-resistant net cage 4 and prevent it from colliding violently with the pedal ring 1. The bottom of the pressure-resistant net cage 4 is provided with a counterweight component 207, and the bottom of the buoyancy ring 205 is provided with a limiting component 208.

[0035] The counterweight assembly 207 includes multiple connecting rings 2071, the outer walls of which are fixedly connected to the bottom of the pressure-resistant net cage 4. A trapezoidal counterweight block 2072 is fixedly connected to the bottom of the connecting ring 2071. The trapezoidal counterweight block 2072 of the counterweight assembly 207 is suspended from the bottom of the net cage through the connecting rings 2071, increasing the overall stability of the net cage and reducing tilting caused by wind and waves. The limiting assembly 208 includes multiple limiting rods 2081, the tops of which are fixedly connected to the bottom of the buoyancy ring 205. A support ring 2082 is fixedly connected to the bottom of each of the multiple limiting rods 2081. The limiting rods 2081 and the support rings 2082 of the limiting assembly 208 further constrain the vertical displacement of the net cage, thereby ensuring that the beating effect of the cleaning mechanism 2 is uniform and stable.

[0036] Specifically, when waves crash against the net cage, the connecting rope 201 at the bottom of the inner wall of the pedal ring 1 swings with the undulations of the waves, causing the arc-shaped striking plate 202 to strike the outer wall of the pressure-resistant net cage 4. The special shape design of the arc-shaped striking plate 202 allows it to conform to the curved surface of the net cage, enhancing the striking effect. At the same time, the striking column 204 inside the cylinder 203 undergoes inertial displacement under the swaying of the waves, repeatedly striking the inner wall of the cylinder 203, generating high-frequency vibrations. This mechanical vibration is transmitted to the surface of the net cage through the arc-shaped striking plate 202, effectively destroying the adhesion of marine attached organisms and causing them to detach. The buoyancy ring 205 provides continuous buoyancy to the cleaning mechanism 2, ensuring that the beating plate is always in an effective working position; the limiting ring 206 restricts the swaying amplitude of the pressure-resistant net cage 4, preventing it from colliding violently with the pedal ring 1; the trapezoidal counterweight block 2072 of the counterweight component 207 is suspended at the bottom of the net cage through the connecting ring 2071, increasing the overall stability of the net cage and reducing tilting caused by wind and waves; the limiting rod 2081 and the support ring 2082 of the limiting component 208 further restrict the vertical displacement of the net cage, thereby ensuring that the beating effect of the cleaning mechanism 2 is uniform and stable.

[0037] Reference Figure 1 , Figure 3 and Figure 5 The material distribution mechanism 3 includes a spray cylinder 301. The outer wall of the spray cylinder 301 is slidably connected to the top of the inner wall of the cone-shaped intercepting net 5. A limiting plate 302 is fixedly connected to the top of the inner wall of the spray cylinder 301. A rotating column 303 is rotatably connected to the inner wall of the limiting plate 302. A propeller blade 304 is fixedly connected to the middle of the outer wall of the rotating column 303. Multiple L-shaped push plates 305 are fixedly connected to the bottom end of the rotating column 303. When water flows into the spray cylinder 301, it impacts the propeller blade 304, causing the rotating column 303 to rotate, thereby driving the water flow. The L-shaped pusher plate 305 rotates synchronously, and the rotating pusher plate evenly throws the feed to all sides. An air bag ring 306 is fixedly connected to the middle of the outer wall of the feed cylinder 301. When the feed is poured into the feed cylinder 301, the feed cylinder 301 is suspended at the top of the cone-shaped interception net 5 by the buoyancy of the air bag ring 306. Its position can be adjusted by sliding along the inner wall of the interception net. Multiple elastic buffer rods 307 are rotatably connected to the top of the inner wall of the feed cylinder 301. One end of each elastic buffer rod 307 is rotatably connected to the top of the feed cylinder 301.

[0038] Specifically, feed is poured into the feed cylinder 301, which is suspended at the top of the conical interception net 5 by the buoyancy of the airbag ring 306. Its position can be adjusted by sliding along the inner wall of the interception net. When water flows into the feed cylinder 301, it impacts the propeller blade 304, which drives the rotating column 303 to rotate, thereby driving the L-shaped push plate 305 to rotate synchronously. The rotating push plate throws the feed evenly to all sides. Through the guiding effect of the conical interception net 5, the feed is dispersed and falls into the pressure-resistant net box 4. At the same time, under the action of the elastic buffer rod 307, the feed cylinder 301 can be kept stable under the waves, thereby realizing automated and uniform feeding.

[0039] Reference Figure 1 , Figure 2 and Figure 6 The fixing assembly 6 includes multiple pull ropes 601, the top ends of which are fixedly connected to the bottom outer wall of the pedal ring 1. A hollow limiting nail 602 is fixedly connected to the bottom end of each pull rope 601. A threaded extrusion post 603 is threadedly connected to the inner wall of the hollow limiting nail 602. Multiple inclined pushers 604 are rotatably connected to the inner wall of the hollow limiting nail 602. In the fixing assembly 6, the hollow limiting nail 602 is sunk to the seabed by the pull ropes 601. The threaded extrusion post 603 is rotated, causing it to descend along the inner wall of the hollow limiting nail 602. The conical head of the threaded extrusion post 603 pushes the multiple inclined pushers 604 outwards, piercing into the seabed sediment to form a barbed structure. Multiple arc-shaped buoyancy plates 7 are fixedly connected to the bottom end of the pedal ring 1. The arc-shaped buoyancy plates 7 are designed to be corrosion-resistant and provide sufficient buoyancy to support the pedal ring 1. An anti-slip assembly is also included. Component 8 includes multiple anti-slip rings 801, with the outer walls of the anti-slip rings 801 respectively opened at the top of the pedal ring 1. Multiple drainage outlets 802 are opened in the middle of the top of the pedal ring 1. The anti-slip rings 801 effectively prevent personnel from slipping. The drainage outlets 802 are radially distributed to drain accumulated water. When waves surge onto the pedal ring 1, the accumulated water quickly flows into the ocean through the drainage outlets 802, avoiding the formation of a slippery surface. The combined design of the anti-slip rings 801 and drainage outlets 802 enables the pedal ring 1 to maintain safe operating conditions even in harsh sea conditions. The inner walls of multiple limiting rings 206 are respectively engaged with the outer walls of corresponding limiting rods 2081. The engaging structure of the limiting rings 206 and the limiting rods 2081 forms a vertical guiding constraint. The surface of the pressure-resistant net cage 4 adopts an anti-adhesion design to reduce the weight of the net cage due to biological attachment and reduce the load on the mooring system and buoyancy components.

[0040] Specifically, in the fixing component 6, the hollow limiting nail 602 is sunk to the seabed by the pull rope 601. The threaded extrusion column 603 is rotated, causing it to descend along the inner wall of the hollow limiting nail 602. The conical head of the threaded extrusion column 603 pushes multiple inclined pushers 604 outward to penetrate the seabed sediment, forming a barbed structure. Compared with traditional gravity anchors, this design increases the contact area and friction with the seabed, significantly improving pull-out resistance. At the same time, the hollow structure reduces the transport weight, facilitating deployment and recovery. When it is necessary to move the cage, the threaded extrusion column 603 is rotated in the opposite direction, and the inclined pushers 604 retract, making anchoring easy. The arc-shaped buoyancy plate 7 provides sufficient buoyancy to support the step ring 1 and reduces the impact of waves through hydrodynamic optimization. The anti-slip ring 801 effectively prevents personnel from slipping. The drainage outlets 802 are radially distributed and can drain completely. When waves surge onto the footplate ring 1, the accumulated water quickly flows into the ocean through the drain outlet 802, preventing the formation of a slippery surface. The combined design of the anti-slip ring 801 and the drain outlet 802 ensures that the footplate ring 1 can maintain safe operating conditions even in harsh sea conditions. The inner walls of multiple limiting rings 206 engage with the outer walls of corresponding limiting rods 2081. The engaging structure of the limiting rings 206 and the limiting rods 2081 forms a vertical guiding constraint. When the pressure-resistant net cage 4 floats up and down with the waves or during the lifting and lowering process, the limiting rings 206 slide along the outer walls of the limiting rods 2081, which can limit the horizontal displacement of the pressure-resistant net cage 4 and prevent it from deviating from the preset position due to water flow impact. The surface of the pressure-resistant net cage 4 adopts an anti-adhesion design to reduce the weight of the net cage due to biological attachment, reduce the load on the mooring system and buoyancy components, and prevent the net cage from sinking or tilting due to excessive weight.

[0041] Working principle: First, when waves crash against the net cage, the connecting rope 201 at the bottom of the inner wall of the pedal ring 1 swings with the undulation of the waves, thereby driving the arc-shaped beater 202 to strike the outer wall of the pressure-resistant net cage 4. Due to its special shape design, the arc-shaped beater 202 can conform to the curved surface of the net cage, thereby enhancing the beating effect. At the same time, the striking column 204 inside the cylinder 203 generates inertial displacement under the action of the waves, repeatedly striking the inner wall of the cylinder 203, forming high-frequency vibration. This mechanical vibration is transmitted to the surface of the net cage through the arc-shaped beater 202, which can effectively destroy the adhesion of marine organisms. The attachment force causes it to fall off. The buoyancy ring 205 provides continuous buoyancy to the cleaning mechanism 2 to ensure that the beating plate is always in an effective working position. The limiting ring 206 restrains the swaying amplitude of the anti-pressure net box 4 to prevent it from colliding violently with the pedal ring 1. The trapezoidal counterweight block 2072 of the counterweight component 207 is suspended from the bottom of the net box through the connecting ring 2071, which can increase the overall stability of the net box and reduce the tilting caused by wind and waves. The limiting rod 2081 and the support ring 2082 of the limiting component 208 further restrain the vertical displacement of the net box, thereby ensuring that the beating effect of the cleaning mechanism 2 is uniform and stable.

[0042] Furthermore, the feed is poured into the feed cylinder 301 through the feed dispensing mechanism 3. The feed cylinder 301 is suspended at the top of the cone-shaped intercepting net 5 by the buoyancy of the air bag ring 306. Its position can slide and be adjusted along the inner wall of the intercepting net. When the water flows into the feed cylinder 301, the water flow impacts the propeller blade 304, which drives the rotating column 303 to rotate, and then drives the L-shaped push plate 305 to rotate synchronously. The rotating push plate throws the feed evenly to all sides. Through the guiding effect of the cone-shaped intercepting net 5, the feed is dispersed and falls into the pressure-resistant net box 4, thereby realizing automated and uniform feeding.
