[0022] The present utility model is a spherical aquaculture net cage with a warp and weft structure. The spherical aquaculture net cage is composed of a spherical wire frame 1, a netting 2, a fixing device 3, a gravity anchor (or sinking stone) 4, and a positioning floating ball 5 (see Figure 1 shown). The spherical wire frame 1 of the present utility model is composed of a number of radial rods 11 and circumferential rods 12. Through the fixing device 3, the connecting parts that intersect with each other are fixed, and finally the structure of the spherical wire frame 1 is formed; the netting 2 is fixed inside the spherical wire frame 1.

[0023] Embodiment 1 (Spherical wire frame structure without baffle):

[0024] Embodiment 1 of the present utility model is a fixing device 3 that cannot install a baffle. The fixing device 3 is a double "U" type clamp 31 (see Figure 2 shown). The netting 2 is installed inside the spherical wire frame 1. The double "U" type clamp 31 serves as a fixed connection node for the radial rod 11 and the circumferential rod 12, and constitutes a spherical aquaculture net cage with relatively simple installation.

[0025] The double "U" type clamp 31 is composed of a double "U" type double-headed screw 311, a pair of first pressing plates 312, and two first nuts 313; the first pressing plate 312 is divided into a first pressing plate upper cover 3121 and a first pressing plate lower cover 3122; among them, the double "U" type double-headed screw 311 is bent into a double "U" shape by a bending device (see Figure 3 , 4 shown). The two ends of the first pressing plate 312 are provided with ears. One end of the ears is matched with the "U" part of the double "U" type screw 311; the two screw holes at the other end of the ears are passed through by two parallel screw heads of the double "U" type double-headed screw 311, and are fixed by two first nuts 313.

[0026] During assembly: First, snap the weft rod 12 into the lower cover 3122 of the first pressing plate, and then snap the warp rod 11 into the upper cover 3121 of the first pressing plate to form a wrapping around the intersection of the weft rod (12) and the warp rod (11). Second, snap the "U" - shaped part of the double "U" - shaped double - headed screw 311 into the ear part of the first pressing plate 312. Third, snap the two juxtaposed screw heads of the double "U" - shaped double - headed screw 311 into the double holes in the other ear part of the pressing plate 312, and tighten and fix with two first nuts 313.

[0027] When the netting 2 is installed inside the spherical grid 1, a most basic structure of the spherical fish - farming net cage is formed.

[0028] Embodiment 2 (Spherical grid structure with baffle):

[0029] Embodiment 2 of the present utility model is a fixing device 3 capable of installing a baffle. The function of the baffle is to reduce the impact of the rapid current on the fish. The fixing device 3 uses a single "U" - shaped clamp 32 (see Figure 5 as shown) to fix the intersection nodes of all the warp rods (11) and weft rods (12), and finally assemble them into a spherical grid 1 structure.

[0030] When the spherical fish - farming net cage is placed underwater, especially in a sea area with a large sea current, a baffle 6 needs to be installed on the spherical fish - farming net cage to enable the fish to avoid the rapid current inside the spherical fish - farming net cage. Usually, the baffle 6 is installed on the fixing device 3 formed by the intersection and installation of the warp rod 11 and the weft rod 12.

[0031] The fixing device 3 of this Embodiment 2 uses a single "U" - shaped clamp 32 as the connection structure between the warp rod 11 and the weft rod 12 (see Figure 5-6 as shown). The single "U" - shaped clamp 32 is a connection device dedicated to installing the baffle.

[0032] The single "U" - shaped clamp 32 is composed of two single "U" - shaped double - headed screws 321, a pair of second pressing plates 322 with four screw holes, and four second nuts 323. Among them, the second pressing plate 322 is divided into an upper cover 3222 and a lower cover 3221 of the second pressing plate, and the lower cover 3221 and the upper cover 3222 of the second pressing plate cooperate with each other. The weft rod 12 and the warp rod 11 are wrapped inside the second pressing plate 322 to form a fixed connection node. Two screw holes are provided on each of the ear rings at both ends of the second pressing plate 322.

[0033] When assembling: First, snap the weft rod 12 into the lower cover 3221 of the second pressing plate, and snap the warp rod 11 into the upper cover 3222 of the second pressing plate, so that the weft rod 322 is located inside the spherical grid 1; Secondly, press the two single "U"-shaped double-headed screws 321 into the four screw holes of the ear rings at both ends of the second pressing plate 322 respectively, and then tighten and fix them with the second nuts 323.

[0034] After the netting 2 is installed inside the spherical grid 1, the basic structure of the spherical aquaculture cage is formed. In the embodiment of the present utility model, the 4 extensions of the two single "U"-shaped double-headed screws 321 are utilized, and a third nut 622 is added to fix the baffle 6.

[0035] Four support feet 61 are further provided under the baffle 6, and the support feet 61 are matched with the screw hole positions of the second pressing plate 322. The 4 screw heads of the two single "U"-shaped screws 321 pass through the middle holes of their respective support feet 61. Each support foot 61 is provided with a through hole for the single "U"-shaped screw to pass through, a step is provided in the middle of the through hole, two nuts 622 and nuts 323 are respectively arranged on both sides of the step, the second nut 323 is used to fix the pressing plate 3222, and the third nut 622 is used to fix the baffle 6. The function of the above structure is that the third nut 622 and the screw 321 are not exposed on the surface of the baffle 6, which can effectively prevent fish from being injured.

[0036] Embodiment 3 (Spherical grid structure for installing a habitat box)

[0037] Embodiment 3 of the present utility model is based on the baffle 6, and a habitat box 7 is further added (see FIGS. 7-8). The function of the habitat box 7 is to provide a better habitat environment for fish. The habitat box is composed of a baffle 6 and an arch-shaped cover, and its purpose is to attract wild fish in the surrounding area to inhabit, which is convenient for the fish cultured in the spherical cage to obtain natural bait, reduces the breeding cost and improves the breeding effect.

[0038] The shape of the habitat box 7 can be designed into a circular plate, an oval plate, a rectangular plate, a square plate, etc. according to needs. At least one biological entrance 71 is provided on the side of the habitat cover 7.

[0039] Embodiment 4 (Making a floating artificial fish reef using a spherical grid):

[0040] Example 4 of the present utility model is an artificial fish reef, which is formed by adding a flow baffle 6 to the spherical grid 1; or by adding a flow baffle 6 and a habitat box 7 to the spherical grid 1; or by adding a transverse pull pipe 8, a longitudinal pull pipe 9 and a habitat box 7 to the spherical grid 1 (see Figure 9). The purpose of adding the flow baffle and the habitat box is to increase the habitat space for marine organisms by increasing the arrangement density of the flow baffle 6 and the habitat box 7. The purpose of adding the transverse pull pipe 8 and the longitudinal pull pipe 9 is to increase the strength of the artificial fish reef. The floating artificial fish reef of this embodiment can be placed in the sea area and used in cooperation with the spherical aquaculture cage, or can be used alone for the habitat and reproduction of wild fish.

[0041] When the artificial fish reef can be used in cooperation with the spherical aquaculture cage, it forms a habitat environment conducive to the growth of natural bait, enabling the bait to avoid the harassment of ocean currents, providing a certain amount of bait for the fish in the spherical aquaculture cage, reducing the breeding cost and improving the breeding effect.

[0042] The artificial fish reef can also be used in the construction of a marine ranch. By releasing a large number of artificial fish reefs in a large sea area, the ecological and aquaculture environment can be improved.
