Description

Ocean fishery aquaculture net cage Technical Field The invention relates to the technical field of maritime fishery cultivation, in particular to an ocean fishery cultivation net cage. Background In recent years, fishery continues to develop rapidly in coastal areas of China, and important contribution is made to social development. But the fishery facilities in China are set behind, and inland or offshore cultivation seriously pollutes the water area. Therefore, the regulation and optimization of the industrial structure of the fishery promotes the transformation and upgrading of the fishery, greatly develops standardized healthy cultivation, reduces inland and offshore cultivation, exploits open sea, and develops ocean cultivation to become a development trend. At present, in ocean fishery cultivation, the floating net cage is widely applied, the floating net cage is easy to observe the cultivation condition in the net cage, the manufacturing cost is low, the net cage structure is relatively stable, but is easily influenced by wind waves, the existing floating net cage is mainly circular or square in structure, the box body frame is a rigid beam which cannot be folded or contracted, the performance of resisting ocean current wind waves is poor, and steel pipes of the net cage are directly subjected to the attack of the wind waves and are easy to damage. Disclosure of Invention The invention provides an ocean fish culture net cage for solving the defects that the existing fish culture net cage is poor in sea current and stormy waves resistance and easy to damage. In order to solve the technical problems, the invention provides the following technical scheme: The utility model provides an ocean fishery aquaculture net cage, includes first flotation pontoon, bracing piece and stop mechanism, bracing piece evenly distributed is in on the first flotation pontoon, the inboard of bracing piece is provided with the net, the bottom of net is provided with gravity adjusting device, the bracing piece includes upper ledge, well frame and lower carriage, the upper ledge is fixed on the first flotation pontoon, the one end of well frame with the upper ledge articulates, the other end of well frame with lower carriage articulates, the middle part fixedly connected with connecting plate of well frame, the middle part of lower carriage is provided with logical groove, be provided with the connecting rod in the logical inslot, stop mechanism sets up on the connecting rod, the connecting plate with the connecting rod is connected, the both ends of connecting rod articulate respectively and have the fly leaf, and the fly leaf between two adjacent bracing pieces articulates. Further, the second pontoon is connected with the below of first pontoon through the mount, the second pontoon passes through the walking platen and is connected with the third pontoon, makes things convenient for technicians to operate the box with a net. Further, the stop mechanism includes upper end stop mechanism and lower extreme stop mechanism, upper end mechanism includes supporting shoe, first baffle, second baffle and jackshaft, the supporting shoe is fixed to be set up on the connecting rod, first baffle with the second baffle sets gradually between the supporting shoe, the jackshaft passes the supporting shoe first baffle and the second baffle, first baffle with all be provided with the spring between the supporting shoe with the second baffle with the structure that upper end stop mechanism with lower extreme stop mechanism contained is the same, upper end stop mechanism with lower extreme stop mechanism is symmetrical setting for the connecting rod, is convenient for control the shrink and the extension of centering frame and lower frame. Furthermore, the cross section shape of the through groove is I-shaped, so that the stop mechanism is convenient to limit the shrinkage of the support rod. Further, the gravity adjusting device is connected to the bottom of the supporting rod through a steel wire rope, and the control effect on shrinkage of the supporting rod is good. Compared with the prior art, the ocean fish culture net cage has the advantages that when encountering stormy waves, the middle frame and the lower frame of the net cage can retract inwards, so that the damage caused by overlarge stress of the net cage frame is avoided, the operation is simple, the production cost is low, the ocean fish culture net cage can be produced in batches, and the ocean fish culture net cage is also suitable for being used with matched equipment in groups. Drawings In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, and it is obvious that the drawings in the following description are only embodiments of the present invention, and that other drawings can be obtained accordin
