Description

Technical Field

[0001] This utility model belongs to the field of marine aquaculture technology, and in particular relates to a top netting fixing structure for marine aquaculture nets. Background Technology

[0002] In the marine aquaculture industry, net cages are core aquaculture equipment, and the effectiveness of fixing the top netting directly affects the safety and economic benefits of aquaculture. With the expansion of aquaculture scale and the popularization of deep-sea aquaculture scenarios, traditional top netting fixing methods have gradually exposed many technical defects and can no longer meet the needs of modern aquaculture.

[0003] Traditional methods of securing the top netting often involve tying it with ropes or directly connecting it with metal hooks. While rope tying is cheaper, it is prone to problems such as rope aging and breakage, and loosening of knots due to long-term immersion in seawater, the impact of wind and waves, and the attachment of marine organisms. This can lead to the netting shifting or even falling off, causing fish fry to escape. According to industry survey data, the loss rate of fish fry due to rope fixation failure can reach 5%-8%, resulting in serious economic losses for aquaculture farmers. At the same time, rope tying is cumbersome, and subsequent maintenance requires frequent disassembly and reassembly, which not only increases labor costs but may also damage the netting fibers during operation, shortening the netting's lifespan. Therefore, a new top netting fixing structure for marine aquaculture nets is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a top netting fixing structure for marine aquaculture nets. By incorporating an anti-slip component, specifically a rubber ring that fits around the hook portion of the net and has anti-slip texture, it relies on high friction to prevent slippage and elastically buffers pressure to reduce fiber breakage. To fix the netting, first rotate the inner threaded cap counterclockwise to release the constraint on the limiting rod, then insert and fix the netting. Afterward, loosen the limiting rod; the elastic metal plate rebounds, causing it to reset and embed itself onto the side of the net hook end away from the hinge groove. Finally, rotate the inner threaded cap clockwise to move it axially along the limiting rod and fit it at the connection between the limiting rod and the end of the net hook, fixing the limiting rod and ensuring the netting is secure. The hook closure solves the problem of traditional top netting fixing methods that mostly rely on rope binding or direct metal hook connection. Although rope binding is cheaper, it is prone to problems such as rope aging and breakage, loosening of knots, and netting displacement or even detachment due to long-term seawater immersion, wave impact, and marine organism attachment. This can lead to fish fry escaping. According to industry survey data, the fish fry loss rate due to rope fixing failure can reach 5%-8%, causing serious economic losses to fish farmers. At the same time, rope binding is cumbersome and requires frequent disassembly and reassembly for maintenance, which not only increases labor costs but may also damage the netting fibers during operation, shortening the netting's lifespan.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a top netting fixing structure for a marine aquaculture net, comprising a core support device supporting a foundation, a float plate installed on top of the support foundation, a fixing ring welded to the top of the float plate, and a fixing mechanism installed on the surface of the fixing ring. The fixing mechanism fixes the netting in place through various adjustments and reinforcement methods. The fixing mechanism includes anti-detachment components, which are in several sets, each set containing identical parts. Each anti-detachment component includes a net hook with an anti-slip rubber ring installed on its inner ring. A hinge groove is provided at the end of the net hook, and a limit rod is connected inside the hinge groove via a pin. An elastic metal sheet is installed inside the hinge groove cavity, and an internal thread cap is threaded onto the outer surface of the limit rod.

[0007] Furthermore, the fixing mechanism also includes a rotating assembly, which consists of several sets of identical components. The rotating assembly is connected to the outer surface of the fixing ring and is used to adjust the angle of the net hook. An adjusting assembly, also consisting of several sets of identical components, is connected to the anti-detachment assembly and the rotating assembly. The adjusting assembly is used to adjust the distance between the net hook and the fixing ring.

[0008] Furthermore, the hook has an irregular shape, and the end of the internal thread cap away from the hinge groove contacts the end of the limiting rod away from the hinge groove. The side of the limiting rod inside the hinge groove cavity contacts the outer surface of the elastic metal sheet. The outer surface of the limiting rod and the outer surface of the connection between the hook and the limiting rod are both provided with threaded grooves that are compatible with the inside of the internal thread cap.

[0009] Furthermore, the rotating assembly includes a rotating ring, and a limiting ring is rotatably connected inside the cavity of the rotating ring. Several internal threaded holes are opened at the inner edge of the limiting ring, and a fixing bolt is inserted at the inner edge of the rotating ring. The outer surface of the fixing bolt is threadedly connected to the inner surface of several internal threaded holes. The fixing bolt passes through the hook and extends to the outside. Nuts are threadedly connected to both ends of the outer surface of the fixing bolt. The inner ring of the limiting ring is welded to the outer surface of the fixing ring.

[0010] Furthermore, the adjusting assembly includes an internally threaded sleeve, the side of which is away from the limiting ring is connected to the outer surface of the mesh hook via a pin, and a threaded rod is internally threaded onto the internally threaded sleeve, the side of which is away from the mesh hook is welded to the outer surface of the limiting ring.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model incorporates an anti-slip component, specifically an anti-slip ring made of rubber, which is fitted onto the hook portion of the net and has anti-slip texture on its surface. High friction prevents slippage, and elastic cushioning reduces fiber breakage. When fixing the net, first rotate the inner thread cap counterclockwise to release the constraint on the limiting rod, then insert the net and install it. Afterward, loosen the limiting rod; the elastic metal sheet rebounds and resets, embedding and aligning with the side of the net hook end furthest from the hinge groove. Finally, rotate the inner thread cap clockwise to move it axially along the limiting rod and fit it at the connection between the limiting rod and the end of the net hook, fixing the limiting rod and sealing the net hook. This reduces the risk of net detachment and fish fry escape, ensuring the safety of fishermen's property.

[0013] 2. This utility model incorporates a rotating component and an adjusting component. Specifically, the rotating ring moves on the outer surface of the limiting ring, and the internal threaded sleeve and threaded rod work together to synchronously drive the net hook. This design adapts to the edges of nets of different sizes. Operators can also adjust the distance between the net hook and the fixed ring according to the net tension: rotating the internal threaded sleeve clockwise along the threaded rod axis towards the rotating ring and driving the net hook to move synchronously. This design allows the rotating ring to rotate flexibly and the net hook to be precisely positioned, improving the device's adaptability to nets of different specifications. By adjusting the net tension, it avoids excessive looseness leading to wrinkle accumulation or excessive tightness causing breakage, creating a good breeding environment and improving breeding efficiency and quality.

[0023] 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.

[0024] Please see Figures 1-5As shown, this utility model is a top netting fixing structure for a marine aquaculture net, including a core support device supporting a base 111, a float 112 installed on the top of the base 111, a fixing ring 113 welded to the top of the float 112, and a fixing mechanism 2 installed on the surface of the fixing ring 113. The fixing mechanism 2 fixes the netting through various adjustments and reinforcements. The fixing mechanism 2 includes anti-detachment components 22, and there are several sets of anti-detachment components 22. The components in the several sets of anti-detachment components 22 are identical. The anti-detachment components 22 include net hooks 221, and an anti-slip rubber ring 222 is installed on the inner ring of the net hooks 221. The end has a hinge groove 223, and a limit rod 224 is connected inside the hinge groove 223 via a pin. An elastic metal sheet 226 is installed inside the cavity of the hinge groove 223. An internal threaded cap 225 is threaded onto the outer surface of the limit rod 224. The fixing mechanism 2 also includes a rotating assembly 21, which consists of several sets of identical components. The rotating assembly 21 is connected to the outer surface of the fixing ring 113 and is used to adjust the angle of the hook 221. There are also several adjusting assemblies 23, which consist of identical components. The adjusting assemblies 23 are connected to the anti-detachment assembly 2. 2. The rotating assembly 21 is connected to the adjustment assembly 23, which is used to adjust the distance between the hook 221 and the fixed ring 113. The hook 221 has an irregular shape. The end of the internal thread cap 225 away from the hinge groove 223 contacts the end of the limiting rod 224 away from the hinge groove 223. The limiting rod 224 is located inside the cavity of the hinge groove 223 and contacts the outer surface of the elastic metal sheet 226. The outer surface of the limiting rod 224 and the outer surface of the connection between the hook 221 and the limiting rod 224 are both provided with threaded grooves that are compatible with the inside of the internal thread cap 225. The anti-slip rubber ring 222 is a rubber ring that is fitted onto the bent part of the hook 221 and the surface is... The surface has anti-slip texture, which relies on high friction to prevent slippage and elastic cushioning to reduce fiber breakage. When fixing the net, first rotate the inner thread cap 225 counterclockwise to release the constraint on the limiting rod 224, and then insert the net for installation and fixation. After that, loosen the limiting rod 224, and the elastic metal piece 226 will rebound and drive it to return to its original position, embedding and aligning with the side of the end of the hook 221 away from the hinge groove 223. Finally, rotate the inner thread cap 225 clockwise to move it along the axial direction of the limiting rod 224 and fit it at the connection between the limiting rod 224 and the end of the hook 221, fixing the limiting rod 224 to close the hook 221, reducing the risk of the net falling off and fish fry escaping, and protecting the property of fishermen.

[0025] The rotating assembly 21 includes a rotating ring 211, with a limiting ring 212 rotatably connected inside the cavity of the rotating ring 211. Several internally threaded holes 213 are formed at the inner edge of the limiting ring 212. Fixing bolts 214 are inserted into the inner edge of the rotating ring 211, and their outer surfaces are threaded into the internal threads of the internal threads 213. The fixing bolts 214 pass through the mesh hook 221 and extend to the outside. Nuts are threaded to both ends of the outer surface of the fixing bolts 214. The inner ring of the limiting ring 212 is welded to the outer surface of the fixing ring 213. The adjusting assembly 23 includes an internally threaded sleeve 231. The side of the internally threaded sleeve 231 away from the limiting ring 212 is connected to the outer surface of the mesh hook 221 via a pin. A threaded rod 232 is threaded into the internal threaded sleeve 231. The threaded rod 232 is welded to the outer surface of the limiting ring 212 on the side away from the hook 221. Rotating the rotating ring 211 causes it to move on the outer surface of the limiting ring 212. With the help of the internal threaded sleeve 231 and the threaded rod 232, the hook 221 is moved synchronously. This design adapts to the edges of different sized nets. The operator can also adjust the distance between the hook 221 and the fixed ring 113 according to the tension of the net: rotating the internal threaded sleeve 231 clockwise along the axial direction of the threaded rod 232 towards the rotating ring 211 and causing the hook 221 to move synchronously. This design allows the rotating ring 211 to rotate flexibly and the hook 221 to be accurately positioned, improving the adaptability of the device to nets of different specifications. By adjusting the tension of the net, it avoids the accumulation of wrinkles due to excessive looseness or the stretching and damage due to excessive tightness, creating a good breeding environment and improving breeding efficiency and quality.

[0026] One specific application of this embodiment is as follows: When in use, the supporting foundation 111 is first used as the bottom load-bearing component and fixed in a preset position in the aquaculture area to ensure that the overall device will not be displaced. The float 112 is assembled with the supporting foundation 111 and the buoyancy is used to keep the top net at a preset water level and buffer the impact of the water flow on the net. Then the fixing ring 113 is welded to the top of the float 112 to support the net.

[0027] During the installation of the mesh, the rotating ring 211 can be rotated to move on the outer surface of the limiting ring 212. During the rotation of the rotating ring 211, the mesh hook 221 is simultaneously driven to move through the internal threaded sleeve 231 and the threaded rod 232, aligning the mesh hook 221 with the edges of mesh of different sizes. After the rotating ring 211 is adjusted to a suitable angle, the fixing bolt 214 is inserted from one side of the rotating ring 211, passing through the internal threaded hole 213 and extending to the other side. Simultaneously, the outer surface of the fixing bolt 214 matches the internal thread of the internal threaded hole 213. The fixing bolt 214 is then secured with two nuts, thus completing the limiting and fixing of the rotating ring 211. Subsequently, the operator can adjust the distance between the mesh hook 221 and the fixing ring 113 according to the tension of the mesh. Specifically, the internal threaded sleeve 231 is rotated clockwise. Because the internal threaded sleeve 231 and the threaded rod 232... The outer thread is compatible, so during the rotation of the inner thread sleeve 231, it will move axially along the threaded rod 232. At this time, the inner thread sleeve 231 will move closer to the rotating ring 211. During the movement of the inner thread sleeve 231, it will drive the net hook 221 to move synchronously. The operator can adjust the tension of the net according to the tension of the net. The rotating ring 211 can rotate flexibly on the outer surface of the limiting ring 212. Through the cooperation of the inner thread sleeve 231 and the threaded rod 232, it drives the net hook 221 to move precisely, so that the net hook 221 can perfectly correspond to the edge of net of different sizes. This greatly improves the adaptability of the device to nets of different specifications and expands the application range of the device. At the same time, by adjusting the tension of the net, the net is always kept in a suitable tension state. This reduces the impact of net wrinkles on the breeding space caused by excessive looseness, and also reduces the damage caused by excessive stretching of the net due to excessive tightness. This is conducive to creating a good breeding environment and improving breeding efficiency and quality.

[0028] The hook 221 has a curved hook structure, with one end rotatably connected to the rotating ring 211, and the other end used to hook the edge mesh of the netting. The anti-slip rubber ring 222 is a ring made of rubber, fitted onto the curved part of the hook 221, and its surface has anti-slip texture. When the hook 221 hooks the netting, the anti-slip rubber ring 222 is in close contact with the netting fibers, and the high friction of the rubber prevents the netting from sliding along the surface of the hook 221. At the same time, the elasticity of the rubber can buffer the local pressure of the hook 221 on the netting, reducing the pressure on the netting. In cases where fibers break due to rigid compression, when securing the mesh, first rotate the internal thread cap 225 counterclockwise. Since the internal thread cap 225 is threadedly connected to the limiting rod 224 and the outer surface of the mesh hook 221, it will move axially along the limiting rod 224 during rotation. At this point, the internal thread cap 225 will disengage from the connection between the limiting rod 224 and the mesh hook 221, releasing the constraint force on the limiting rod 224. The limiting rod can then be... When the limit rod 224 is moved inward towards the hook 221, the connection between the limit rod 224 and the hinge groove 223 will compress the elastic metal sheet 226. The elastic metal sheet 226 will then accumulate force under this pressure. At this point, the netting can be inserted into the hook 221 for installation and fixation. Then, the limit rod 224 is released. The elastic metal sheet 226 will then generate a certain rebound force, causing the limit rod 224 to reset. After the limit rod 224 resets, it will be away from the end of the hook 221, away from the hinge groove 223. When one side is embedded and overlapped, the internal thread cap 225 is rotated clockwise. At this time, the internal thread cap 225 will move axially along the limiting rod 224 again, and the internal thread cap 225 will be sleeved at the connection between the limiting rod 224 and the end of the hook 221, thereby fixing the limiting rod 224 and keeping the hook 221 in a closed state. This reduces the chance of the net falling off and the chance of fish fry escaping and being lost, and protects the property safety of fishermen. At the same time, the outer surface of the entire device structure is coated with anti-corrosion material.
