Description

Technical Field

[0001] The present invention relates to the technical field of net cages, and in particular to a rope net cage frame system. Background Art

[0002] With the development of marine aquaculture technology, marine aquaculture devices such as marine aquaculture cages, which float on the sea surface or are suspended in the seawater, have emerged. These cages typically use buoyancy tubes to provide buoyancy, allowing the marine aquaculture devices to float or suspend in the sea. The buoyancy tubes form a buoyancy frame, upon which the cages are constructed. Furthermore, anchor ropes are tied to the buoyancy tubes and connected to anchor points, allowing the entire marine aquaculture device to be fixed on the sea surface and withstand certain wind and waves.

[0003] However, because the energy of waves and tides acts directly on the cages through the ropes, the mooring points of the anchor ropes and buoyancy tubes are prone to deformation, which can damage the buoyancy tubes and even the cages over time. Currently, a common protective measure is to reinforce the mooring anchor ropes of the buoyancy tubes. This involves adding a ferrule, fitting it over the mooring anchor ropes of the buoyancy tubes, and securing it to increase the load-bearing capacity of the mooring points of the buoyancy tubes and prevent deformation and damage to the buoyancy tubes. While this approach alleviates the problem of deformation or damage to the mooring points of the anchor ropes and buoyancy tubes to a certain extent, the nature of the buoyancy tubes as load-bearing structures remains unchanged, and in the long run, the service life of the buoyancy tubes remains relatively short. Summary of the Invention

In addition, the connection method of the present invention is mainly rope tying, which is easy to operate and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment discloses a rope cage frame system, which includes four buoyancy tubes 1, a first rope 2, eight first anchor points 3, and eight first anchor ropes 4. The first ropes 2 and first anchor ropes 4 are both made of ultra-high molecular weight polyethylene, which is high in strength and resistant to seawater corrosion, thereby ensuring the service life of the above rope components.

[0033] Four buoyancy tubes 1 are joined sequentially (via right-angle elbows) to form a square buoyancy frame. This arrangement provides a simple structure and is easy to manufacture. The buoyancy frame is positioned directly in the direction of the water flow, with two opposing buoyancy tubes 1 parallel to the water flow and the other two opposing buoyancy tubes 1 perpendicular to the water flow.

[0034] The first rope 2 loops around the edge of the buoyancy frame and connects end to end, forming a loop that fits the size of the buoyancy frame. The first rope 2 is securely connected to the buoyancy frame. Specifically, the first rope 2 is tied to the buoyancy frame via several second ropes 5, which are spaced apart on the first rope 2. In this case, the first rope 2 is a multi-strand rope. The second ropes 5 pass through the first rope 2. By twisting the first rope 2 in the opposite direction, the strands of the multi-strand rope can be loosened and dispersed, allowing the second ropes 5 to pass through the first rope 2. After the second ropes 5 pass through the first rope 2 and wrap around it at least once, this arrangement prevents the second ropes 5 from sliding relative to the first rope 2, maintaining a relatively stable connection between the first and second ropes 5. After the second ropes 5 pass through and wrap around the first rope 2, the ends of the second ropes 5 are passed around the buoyancy tubes 1 at their current locations and tied, thus securing the first rope 2 to the buoyancy frame. This connection further enhances the stability of the buoyancy frame. The second ropes 5 are made of the same material as the first rope 2.

[0035] The positions of the first ropes 2 corresponding to the four corners of the buoyancy frame are inflection points. That is, the first rope 2 has four inflection points, and each inflection point corresponds to two first anchor ropes 4. The first anchor ropes 4 correspond one-to-one with the first anchor points 3. One end of the first anchor rope 4 is connected to the first anchor point 3, and the other end of the first anchor rope 4 is connected to the inflection point. When looking down at the buoyancy frame, of the two first anchor ropes 4 connected to the same inflection point, one first anchor rope 4 is aligned with the rope segment of the first rope 2 on one side of the inflection point, and the other first anchor rope 4 is aligned with the rope segment of the first rope 2 on the other side of the inflection point. To facilitate the connection of the first anchor ropes 4 to the inflection points, two third ropes 6 can be pre-connected at the inflection points, and the first anchor ropes 4 can be directly connected to the third ropes 6. With this arrangement, the four first anchor ropes 4 are parallel to the water flow. When the buoyancy frame is pushed by waves and tides, the first ropes 2 and the first anchor ropes 4 serve as the force points of the frame system. The energy of waves and tides is primarily applied to the first anchor ropes 4 and the first ropes 2. The arrangement of the first ropes 2 disperses the energy throughout the frame system, reducing the pulling force of the first anchor ropes 4 on the buoyancy frame, making it less susceptible to deformation and damage, and extending the service life of the buoyancy tube 1. The third rope 6 is made of the same material as the first rope 2.

[0036] In addition, in order to prevent marine organisms from gnawing and attaching, a protective tube 7 can be installed outside the first rope 2, the third rope 6 and the first anchor rope 4. The connection node between the first rope 2 and the second rope 5 can be connected by setting a pipe tee to achieve diversion.

[0037] Example 2:

[0038] like Figure 5 As shown, this embodiment differs from the first embodiment in that it further includes at least one fourth rope 8, at least two second anchoring lines 9, and at least two second anchoring points 10. The fourth ropes 8 are placed within the buoyancy frame and spaced apart. One end of the fourth rope 8 is connected to the first rope 2 segment on the first side of the buoyancy frame, while the other end of the second rope 5 is connected to the first rope 2 segment on the second side of the buoyancy frame. The first side and the second side are in opposite directions. The length of the fourth rope 8 is parallel to the direction of water flow. Each fourth rope 8 corresponds to two second anchoring lines 9, and these two second anchoring lines 9 are located at either end of the fourth rope 8. One end of the second anchoring line 9 is connected to the second anchoring point 10, and the other end of the second anchoring line 9 is connected to the node where the fourth rope 8 connects to the first rope 2. When viewed from above, the fourth rope 8 and its corresponding second anchoring line 9 are aligned. This arrangement strengthens the frame system in the primary force direction (i.e., the direction of water flow), providing greater stability and better protection for the buoyancy tube 1. The fourth rope 8 and the second anchor rope 9 are also provided with a protective tube 7 on the outside, which is also made of ultra-high molecular weight polyethylene.

[0039] Example 3:

[0040] like Figure 6 and Figure 7 As shown, this embodiment differs from the second embodiment in that it also includes at least one fifth rope 11, at least two third anchor lines 12, and at least two third anchor points 13. The fifth ropes 11 are placed in the buoyant frame and spaced apart. One end of the fifth rope 11 is connected to the segment of the first rope 2 on the third side of the buoyant frame, and the other end of the second rope 5 is connected to the segment of the first rope 2 on the fourth side of the buoyant frame. The third side and the fourth side are in opposite directions. The first, second, third, and fourth sides constitute the four sides of the buoyant frame. In this embodiment, the length of the fifth rope 11 is perpendicular to the direction of water flow. Each fifth rope 11 corresponds to two third anchor lines 12, and these two third anchor lines 12 are located at opposite ends of the fifth rope 11. One end of the third anchor line 12 is connected to the third anchor point 13, and the other end of the third anchor line 12 is connected to the node where the fifth rope 11 connects to the first rope 2. When viewed from above, the fifth rope 11 and its corresponding third anchor line 12 are aligned. This arrangement strengthens the secondary force direction of the frame system (i.e., the direction perpendicular to the water flow), further improving the stability of the frame system and providing better protection for the buoyancy tube 1. The fifth rope 11 and the third anchor rope 12 are also covered with a protective tube 7, which is also made of ultra-high molecular weight polyethylene.

[0041] Furthermore, a walkway 14 and guardrails 15 can be installed on the buoyancy frame to facilitate fishermen's feeding, fishing, and other operations. The installation of the walkway 14 and guardrails 15 can refer to existing cage frames and are state-of-the-art, so this will not be described in detail. Of course, a certain number of buoyancy tubes 1 can also be added to improve the stability of the walkway 14 and enhance the buoyancy of the frame system.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
