Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture equipment, specifically a deep-sea cage connection device to prevent mesh wear. Background Technology

[0002] With the maturation of deep-sea aquaculture technology, aquaculture equipment is gradually developing towards larger scales. Segmented aquaculture equipment, which can encompass more aquaculture space, has been widely used in recent years. The frame system of segmented aquaculture equipment is mostly composed of rigid structures such as metal and fiberglass composite materials. The netting and ropes are made of flexible woven chemical fibers. The ropes are connected in an interlaced manner through metal connectors welded to the frame columns. The netting covers and is anchored to the ropes. At the installation positions of the metal connectors on the inside of the frame columns, strip round steel parallel to the columns is welded. The edge ropes around the netting are anchored to the strip round steel to achieve a tight connection with the columns, thus forming the aquaculture water body.

[0003] Existing segmented aquaculture equipment, referred to here as net cages, has gaps at the connection points between the flexible netting and the posts, allowing some farmed fish to escape. Furthermore, the flexible netting experiences continuous friction with the rigid frame system under wave action, easily leading to mesh enlargement and rope wear. Damage to these net cages can result in significant losses, including fish fry escaping. Therefore, protecting the netting is paramount during the connection and installation of deep-sea net cages. Minimizing contact between the netting and the frame, and extending the lifespan of the netting, are crucial to reducing aquaculture risks. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a deep-sea net cage connection device that prevents netting wear, effectively protecting the ropes and nets, extending the service life of the netting, reducing aquaculture risks, and featuring a simple structure and easy installation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A deep-sea cage connection device for preventing mesh wear includes a rigid frame system for cage connection and several rope nets installed on the rigid frame system. Each rope net includes a mesh, edge ropes, and support ropes. The edge ropes are fixedly installed around the perimeter of the mesh, and metal connectors are provided at both ends of the support ropes. The rigid frame system is composed of several columns connected together, and the columns are interconnected to form several frame units for fixing the rope nets. Rigid connectors are evenly spaced on each column, and the support ropes are interconnected with the rigid connectors through the metal connectors. The netting is fixedly connected within the frame unit to form a support grid. The netting covers the support grid and is connected to each column of the frame unit. A strip of round steel is fixedly installed inside the column of each frame unit. The strip of round steel is parallel to the column as a whole. At each rigid connector, it is bent into an arc shape to form an arc-shaped support. The edge rope around the netting is anchored to the strip of round steel by stitching. The arc-shaped support is set to be on the same plane as the connected netting. Multiple layers of wear-resistant mesh are sewn onto the netting on the side adjacent to the connection between the rigid connector and the metal connector.

[0007] The strip-shaped round steel is fixed to the inside of the frame unit by intermittently arranged wedge-shaped welded parts on the whole round steel.

[0008] The spacing between every two wedge-shaped welded parts is set to 0.4-0.8m, and the length of each wedge-shaped welded part is less than the length of the mesh foot.

[0009] The angle between the inclined surface of the arc-shaped support and the plane of the rigid connector is set to 40-140°.

[0010] This invention features a strip of round steel fixed inside each frame unit of a deep-sea net cage rigid frame system. This strip of round steel is fixed around the frame unit and bends into an arc-shaped support with an inclined surface above each connection point between the rope and the rigid connector of the column. The edge rope of the net is anchored to the strip of round steel via stitching. At the connection points of the metal connectors, the net is in a supported state and does not contact the connectors. Furthermore, multiple layers of wear-resistant mesh are designed in this area to reduce contact between the net and the metal parts, effectively protecting the net, increasing its wear resistance, reducing the risk of wear on the main net, and extending its service life. The net also fills the gaps between the metal connectors and the rope, preventing fish fry from escaping and reducing aquaculture risks. The structure is simple, the installation cost is low, and the practical effect is good, making it suitable for large-scale promotion and application. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0013] like Figure 1 As shown, the deep-sea cage connection device for preventing mesh wear includes a cage connection rigid frame system 1 and several rope nets 2 installed on the rigid frame system 1. Each rope net 2 includes a mesh 21, a side rope 22, and a tension rope 23. The side rope 22 is fixedly installed around the mesh 21. Metal connectors 24 are respectively provided at both ends of the tension rope 23. The rigid frame system 1 is composed of several columns connected together. The columns are interconnected to form several frame units for fixing the rope nets 2. Rigid connectors 11 are equally spaced on each column. The tension ropes 23 are connected to the rigid connectors 11 through the metal connectors 24. Interlocking and fixed connections form a support grid within the frame unit. The mesh 21 covers the support grid and connects to each column of the frame unit. Strip round steel 12 is fixedly installed inside the column of each frame unit. The strip round steel 12 is parallel to the column as a whole. At each rigid connector 11, it is bent into an arc shape to form an arc support 13. The side strips 22 around the rope net 2 are anchored to the strip round steel 12 by stitching. The arc support 13 is set to be on the same plane as the connected mesh 21. Multiple layers of wear-resistant mesh 25 are sewn onto the mesh 21 on one side adjacent to the connection between the rigid connector 11 and the metal connector 24.

[0014] As a preferred embodiment, the strip round steel 12 is fixedly installed on the inner side of the frame unit by setting wedge-shaped welded parts 14 at intervals along the whole round steel. The whole strip round steel 12 is fixed by the wedge-shaped welded parts 14, which has high firmness and low welding cost.

[0015] As a preferred embodiment, the spacing between every two wedge-shaped welded parts 14 is set to 0.4-0.8m, and the length of each wedge-shaped welded part 14 is less than the length of the mesh foot of the net 21. This ensures welding strength while controlling welding costs. The length of the wedge-shaped welded part 14 is designed to be less than the length of the mesh foot of the net 21. If it is longer than the length of the mesh foot, it will easily cause the risk of fish fry escaping.

[0016] As a preferred embodiment, in this embodiment, the angle between the inclined surface of the arc-shaped support 13 and the plane of the rigid connector 11 is set to 40-140°. The design of this angle depends on the size of the mesh 21, so that the arc-shaped support 13 is on the same plane after connecting the mesh 21, avoiding excessive support and damage to the mesh 21.

[0017] In the specific installation process of this utility model, the net 21 and the surrounding edge ropes 22 are first sewn together. Marks are made at the positions where wear-resistant mesh 25 needs to be sewn, and the wear-resistant mesh 25 is then sewn. Finally, during installation, the entire edge rope 22 is anchored to the whole strip of round steel 12 through the sewing thread. This results in the rigid connector connecting the force line 23 to the column and the net 21 above it being basically in no contact. Even if there is contact under the impact of waves, the side of the net 21 adjacent to the rigid connector is protected by the wear-resistant mesh 25, avoiding direct wear of the net 21. This effectively protects the high-performance rope net 2 and greatly reduces the risk of fish fry escaping and other aquaculture risks.

[0018] This utility model is easy to install and operate. The entire strip of round steel 12 is welded to the column at certain intervals by wedge-shaped welding parts. It is low in cost, the welding is firm, it increases the wear resistance of the high-performance rope net 2, reduces the risk of damage to the net 21, extends the service life of the rope net 2, reduces the maintenance frequency of rope net accessories, and improves the promotion efficiency of deep-sea aquaculture cages.

[0019] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
