[0039] like Figures 1-10 As shown, this utility model provides a submerged sea urchin aquaculture cage 10, including a cage frame 110 and an aquaculture net 120. The cage frame 110 is a rectangular frame structure, and the aquaculture net 120 is detachably fixed inside the cage frame 110.

[0040] The bottom of the left and right sides of the net cage frame 110 is provided with counterweight pipes 130, and the two counterweight pipes 130 are symmetrically arranged. The counterweight pipes 130 facilitate the sinking of the sea urchin farming net cage 10 into the seabed. The four sides of the net cage frame 110 are provided with lifting frames 140, which are used to facilitate farmers to hook and lift the cage with hooks during harvesting.

[0041] The aquaculture net 120 is provided with several trumpet-shaped net sleeves 121. The top of the trumpet-shaped net sleeves 121 is provided with a float 150 and an openable net opening. After the sea urchin aquaculture cage 10 sinks to the seabed, the float 150 drags the trumpet-shaped net sleeves 121 due to buoyancy, so that its net opening is located near the sea level, making it convenient for farmers to open the net opening to feed the urchins.

[0042] The net cage frame 110 is a rectangular frame structure, and has four edges; specifically, the net cage frame 110 comprises four top longitudinal pipes 111, two bottom longitudinal pipes 112, eight horizontal pipes 113, sixteen vertical pipes 114 and a plurality of pipe clamps 115; two of the four top longitudinal pipes 111 form a group, and each group of the top longitudinal pipes 111 is fixed by a plurality of pipe clamps 115, and the two groups of the top longitudinal pipes 111 are parallel to each other and are arranged in the longitudinal direction; the two bottom longitudinal pipes 112 are arranged immediately below the two groups of the top longitudinal pipes 111 and are spaced apart from the top longitudinal pipes 111 by a certain distance; two of the eight horizontal pipes 113 form a group, and each group of the horizontal pipes 113 is fixed by a plurality of pipe clamps 115; the two groups of the horizontal pipes 113 and the two groups of the top longitudinal pipes 111 form a top rectangular frame, and the two groups of the horizontal pipes 113 and the two bottom longitudinal pipes 112 form a bottom rectangular frame; two of the sixteen vertical pipes 114 form a group, and each group of the vertical pipes 114 is fixed by a plurality of pipe clamps 115, and the eight groups of the vertical pipes 114 are arranged between the top rectangular frame and the bottom rectangular frame.

[0043] Both ends of the horizontal pipe 113 are provided with end sleeve pipes 116, and both ends of the vertical pipe 114 are also provided with end sleeve pipes 116; the end sleeve pipes 116 at both ends of the horizontal pipe 113 are sleeved on the top longitudinal pipe 111 or the bottom longitudinal pipe 112, and the end sleeve pipes 116 at both ends of the vertical pipe 114 are sleeved on the horizontal pipe 113, the top longitudinal pipe 111 or the bottom longitudinal pipe 112. Taking the horizontal pipe 113 in the top rectangular frame as an example, both ends of the horizontal pipe 113 are provided with end sleeve pipes 116, and the two end sleeve pipes 116 are sleeved on the top longitudinal pipes 111 on both sides; the two sides of the end sleeve pipe 116 on the top longitudinal pipe 111 are provided with pipe clamps 115, and the pipe clamps 115 on both sides clamp the end sleeve pipe 116 to limit the end sleeve pipe 116, so as to prevent the horizontal pipe 113 from moving along the axis direction of the top longitudinal pipe 111, and avoid deformation of the net cage frame 110 under the action of sea waves. The fixing modes of the horizontal pipe 113 and the vertical pipe 114 are the same, and those skilled in the art can easily reproduce them according to the above description and the drawings in the specification, so they will not be described again.

Taking the fixation of two horizontal pipes 113 as an example, the two horizontal pipes 113 pass through the two through holes respectively, the pipe clamp 115 is adjusted to the appropriate position, then the bolt passes through the locking screw hole 115a, and the nut on the bolt is tightened, so that the gap 115b gradually reduces the interval, so as to reduce the diameter of the two through holes, and finally achieve the purpose of fixing the two horizontal pipes 113. The fixing mode of other pipes is the same, which will not be repeated.

[0052] The main body of the culture net 120 is a cuboid structure, which is embedded in the net cage frame 110 and detachably fixed on the net cage frame 110 by a rope 133, a buckle or other tools when in use; the top surface of the main body of the culture net is provided with four horn-shaped net sleeves 121, the top end of each horn-shaped net sleeve 121 is fixed with a floating ball 150, and the net opening of each horn-shaped net sleeve 121 is usually tied tightly and floats on the sea surface; when it is necessary to put kelp, seaweed, sea urchin feed and the like into the culture net 120, the net opening of each horn-shaped net sleeve is opened, the feeding is completed, and then the net opening is tied tightly and the floating ball 150 is fixed.

[0053] The material of the culture net 120 is the prior art, which is a net-shaped structure for aquaculture and is made of high-strength and corrosion-resistant materials such as nylon and polyethylene. It can isolate the cultured animals in a certain space while allowing water to flow freely, thereby providing a suitable growth environment for the cultured animals.

[0054] During culture, the user puts sea urchin larvae into the culture net 120 from the net opening, then sinks the culture net into the seabed, then regularly puts feed into the net opening according to the culture requirements, and finally hoists the culture net to harvest the mature sea urchins in the harvesting season.

[0055] The above description is only optional embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the inventive concept of the present application and the content of the present application specification and drawings are included in the patent protection scope of the present application.
