Detailed Implementation

[0028] 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.

[0029] like Figures 1 to 5 As shown, a deep-sea cage aquaculture net cage includes a netting device 2, a cage frame for wrapping the netting device 2, and a feeding hole 34.

[0030] The cage frame includes an upper fixed plate 31, several arc-shaped claw steel frames 32, and a lower fixed plate 33;

[0031] The upper fixed plate 31 has a feeding hole 34 in the center, and a number of first connecting parts 311 are arranged around the outer edge of the upper fixed plate 31. One end of each arc-shaped claw steel frame 32 is fixed to one of the first connecting parts 311 of the upper fixed plate 31 through a first connecting member. The number of arc-shaped claw steel frames 32 matches the number of first connecting parts 311.

[0032] The lower fixed plate 33 has a first fish outlet hole 331 for releasing fish and a cover 333 for opening and closing the first fish outlet hole 331 by a number of screws 332. The outer edge of the lower fixed plate 33 is surrounded by a number of second connecting parts 334. The other end of each arc-shaped claw steel frame 32 is fixed to one of the second connecting parts 334 of the upper fixed plate 31 by a second connector.

[0033] By setting the ingot screws 332 and the cover 333 that can open and close the first fish outlet hole 331, if fish need to be released, the ingot screws 332 at the bottom are removed one by one, and then the cover 333 is opened to connect the first fish outlet hole 331 with the outside world for fish release.

[0034] Each arc-shaped claw steel frame 32 has several connecting rings 4 arranged from top to bottom for connecting the mesh device 2 to the cage frame;

[0035] The mesh garment device 2 includes horizontal bars, vertical bars, and mesh panels. A plurality of the horizontal bars and vertical bars are interwoven with each other and woven with the mesh panels to form a mesh garment structure. A zipper assembly is sewn onto the mesh garment structure, and the zipper assembly has a zipper structure for partially opening the mesh garment device 2.

[0036] The netting structure is formed by interlacing horizontal and vertical wires and mesh sheets. This not only maintains the strength of the netting structure but also ensures sufficient aquaculture volume and improves the toughness of the netting structure, making it less prone to damage.

[0037] The bottom of the mesh structure is connected to the lower fixing plate 33 and communicates with the first fish outlet 331.

[0038] Using the above structure, by combining several arc-shaped claw steel frames 32 with the upper fixed plate 31 and the lower fixed plate 33 through the first and second connecting parts, a cage-type aquaculture net cage with four, six, or eight claws is set up. The strength of the net cage's resistance to typhoons can be assessed based on the location of the cage-type aquaculture net cage, whether in the near or far sea. The net cage is suspended on a floating rope on the sea surface and submerged underwater. The upper fixed plate 31 is fixed to the three rings of the upper fixed plate 31 by ropes, connected to the ropes on the sea surface, and suspended underwater, thus providing good resistance to typhoons and waves. In deep-sea aquaculture, it has good wind and wave resistance and can effectively resist typhoons. Simultaneously, by setting an upper fixed plate 31, several arc-shaped claw steel frames 32, and a lower fixed plate 33, the first connecting part 311 between the upper end of the arc-shaped claw steel frame 32 and the upper fixed plate 31 is installed by threaded connection through a first connector. The second connecting part 334 between the lower end of the arc-shaped claw steel frame 32 and the lower fixed plate 33 is installed by a second connector. Each arc-shaped claw steel frame 32 has a connecting ring 4 along its outer wall on the side near the netting device 2. The net rope on the netting structure is tied to the connecting hole of the connecting ring 4 for connection and fixation. By adding a zipper structure to the netting device 2, multiple fish release options are available when it is necessary to release the fish. 1. Opening the zipper structure allows the net device 2 to be opened, leaving a large square opening, called a fish outlet channel, which allows fish to be released. At the same time, the fish outlet channel is closed by zipping up the structure. 2. By removing the bottom screws 332 one by one, and then opening the cover 333, the first fish outlet hole 331 is connected to the outside, allowing fish to be released. 3. By simultaneously opening the zipper structure to open the net device 2, leaving a large square opening, and opening the cover 333 to connect the first fish outlet hole 331 to the outside, the device can not only release fish from the bottom first fish outlet hole 331, but also release fish by opening the zipper structure to form a fish outlet channel. This structure allows for the placement of the first fish outlet 331 at its lower part, and the netting device 2 is equipped with a zipper structure that can partially open the netting device 2 to leave a large square opening, increasing the number of fish that can be taken out and making it easier to take out fish. At the same time, it greatly improves the efficiency of taking out fish, making it more convenient and faster. The cap 333 and zipper structure can be flexibly opened or closed as needed to adjust the amount of fish taken out, making it more practical. In addition, this cage-type aquaculture net cage is submerged in water and has good wind resistance.

[0039] In this invention, some dead fish inside the netting device can also be collected by gravity sinking to the bottom of the netting device; when the first fish outlet 331 is opened to release live fish, dead fish will also be released at the same time, which is conducive to quickly releasing live fish and dead fish by gravity.

[0040] Specifically, such as Figures 1 to 5As shown, the zipper structure includes two symmetrically arranged longitudinal zipper fabrics 51 and a transverse zipper fabric 52. Both ends of the transverse zipper fabric 52 are connected to both ends of the longitudinal zipper fabrics 51, and together they form a whole zipper fabric. A zipper piece 53 for opening the zipper fabric is installed on the whole zipper fabric.

[0041] Using the above structure, two longitudinal zipper fabrics 51 and one transverse zipper fabric 52 are set. The longitudinal zipper fabrics 51 and the transverse zipper fabric 52 are set in a perpendicular direction. The two longitudinal zipper fabrics 51 are divided into a first longitudinal zipper fabric 51 and a second longitudinal zipper fabric 51. The upper end of the first longitudinal zipper fabric 51 is connected to the left end of the transverse zipper fabric 52, and the second longitudinal zipper fabric 51 is connected to the right end of the transverse zipper fabric 52. The zipper fabric as a whole includes the first longitudinal zipper fabric 51, the second longitudinal zipper fabric 51 and the transverse zipper fabric 52. It forms a zipper section from the bottom end of the first longitudinal zipper fabric 51, through the transverse zipper fabric 52 to the bottom of the second longitudinal zipper fabric 51. The zipper component 53 is set on the zipper section, which is conducive to partially opening the net device 2 to leave a large square zipper structure, increasing the number and size of fish that can be taken out, making it easier to take out fish, and greatly improving the efficiency of taking out fish, making it more convenient and faster.

[0042] like Figures 1 to 5 As shown, the bottom of the upper fixing plate 31 is surrounded by several spring hinge structures 6 for preventing fish from escaping.

[0043] By setting a spring hinge structure 6 at the upper fixed plate 31, it is helpful to prevent and block fish from escaping from the top. At the same time, a feeding net channel 7 is also set at the feeding hole 34. The bait is fed into the net device 2 by first opening the spring hinge structure 6 and then feeding the fish inside the net device 2 through the feeding net channel 7. This makes it convenient to feed the fish.

[0044] like Figures 1 to 5 As shown, the first connecting member is the first bolt 81, and the upper fixing plate 31 is connected to the upper ends of several of the arc-shaped claw steel frames 32 by the first bolt 81.

[0045] The presence of the first bolt 81 facilitates the secure connection between the upper fixing plate 31 and the arc-shaped claw steel frame 32, ensuring a reliable connection and easy assembly and disassembly.

[0046] like Figures 1 to 5 As shown, the second connecting member is the second bolt 82, and the lower fixing plate 33 is connected to the lower ends of several of the arc-shaped claw steel frames 32 by the second bolt 82.

[0047] By setting a second screw, it is easier to connect the lower end of the arc-shaped claw steel frame 32 to the lower fixed plate 33, ensuring a secure fixation while also facilitating easy assembly and disassembly.

[0048] like Figures 1 to 5 As shown, the arc-shaped claw steel frame 32 is manufactured using an integral bending process. The integrally bent stainless steel body provides higher strength. Furthermore, the number of arc-shaped claw steel frames 32 is changed from none to six arc-shaped claw steel frames with four claws, six arc-shaped claw steel frames with six claws, or eight arc-shaped claw steel frames with eight claws. The arc-shaped claw steel frames 32 are connected to the upper and lower fixed frames, and are used for deep-sea aquaculture. They also have good wind and wave resistance, can withstand typhoons, and greatly improve the overall strength of the device, making the structure more stable and reliable, and significantly extending the service life of the device.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0050] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them.
