Embodiment
Now by reference to the accompanying drawings the utility model is further described:
Shown in accompanying drawing Fig. 1, Fig. 3, the floating circular net cage for yellow croaker cultivation described in the present embodiment, comprises circular frame, is located at cylindrical circular side net sheet 1 on framework and is connected to the circular spacer screen sheet of side net sheet 1 bottom peripheral edge.Described side net sheet 1 is outer is arranged with a rotation net sheet 2, and cylindrical and its surface uniform of described rotation net sheet 2 is distributed with the mesh identical with side net sheet 1 aperture.Wherein, described rotation net sheet 2 internal diameters can be made as the 1.05-1.2 of side net sheet 1 external diameter, and side net sheet 1 can relatively rotate and stagger with rotation net sheet 2, schematic diagram when Fig. 1 and Fig. 2 are both and stagger different angles.
In the present embodiment, lock solid structure between side net sheet 1 and rotation net sheet 2 is as follows: described side net sheet 1 top edge evenly convexes with a plurality of cylindrical projections 3 along its circumference, on described rotation net sheet 2 top edge correspondence positions, offer the chute 5 suitable with projection 3, described projection 3 is located in chute 5 and horizontally slips along chute 5.Wherein, described projection 3 quantity are 4-6 and are evenly distributed on same circumference, and side net sheet 1 coaxially be socketed with rotation net sheet 2, guarantee both respectively to balance.
More specifically, shown in Fig. 3 and Fig. 4, described chute 5 includes a plurality of clamping hole 5-1 and connects successively the narrow contracting section 5-2 being connected between two clamping hole 5-1, and clamping hole 5-1 and narrow contracting section 5-2 interval arrange.The width of described narrow contracting section 5-2 is less than the aperture of clamping hole 5-1, and the aperture of clamping hole 5-1 is identical with the diameter of projection 3; Engaging by one of them clamping hole 5-1 in projection 3 and chute 5 between described side net sheet 1 and rotation net sheet 2 is connected.Interval just because of described narrow contracting section 5-2 arranges and size restrictions, between clamping hole 5-1 in same chute 5, there is the restriction of transverse shifting, can effectively avoid projection 3 arbitrarily in more adjacent another clamping hole 5-1 of clamping hole 5-1, be that projection 3 only could be passed through relatively narrower narrow contracting section 5-2 applying under certain External Force Acting, reach closely fixing object, safer reliable.In order to realize the diversity of mesh size, the clamping hole 5-1 quantity in a described chute 5 is made as 2-4, and when projection 3 is convexly equipped with in different clamping hole 5-1, the angle that staggers between side net sheet 1 and rotation net sheet 2 is also different.
In the present embodiment, the sectional dimension that described projection 3 tops are also provided with Anti-slip cover 4 and Anti-slip cover 4 is greater than projection 3 diameters, and its Main Function is to come off from clamping hole 5-1 for fear of projection 3, prevents that the connection between side net sheet 1 and rotation net sheet 2 is lax.Simultaneously, for the ease of the flexible installation and removal between side net sheet 1 and rotation net sheet 2, between described Anti-slip cover 4 and projection 3, adopt removably to be connected, its concrete syndeton is with reference to shown in Fig. 4: described Anti-slip cover 4 has an axis hole 4-1 who wears for projection 3, described axis hole 4-1 inwall is provided with internal thread 4-2, and described projection 3 tops are provided with the external screw thread 3-1 suitable with internal thread 4-2; Described Anti-slip cover 4 is set in projection 3 and cooperation and projection 3 by internal thread 4-2 and external screw thread 3-1 are connected.
During first installation, first, rotation net sheet 2 is socketed in outside side net sheet 1, according to actual mesh needs, selects one of them the clamping hole 5-1 in chute 5; Secondly, rotation net sheet 2 rotates to an angle, and each projection 3 correspondence is located in the clamping hole 5-1 of this position in each chute 5; Finally, the projection 3 sheathed upper Anti-slip covers 4 in top are realized and being threaded.In use procedure, while needing to adjust mesh size, promote successively projection 3 and be fastened in another clamping hole 5-1 via narrow contracting section 5-2.
The present embodiment can make mesh that certain angular misalignment occur with the relative rotation of side net sheet 1 by rotation net sheet 2, thereby adjusts the size of mesh, has expanded the scope of application of net cage, is applicable to the different phase of yellow croaker cultivation, has extremely strong versatility.At the yellow croaker cultivation initial stage, mesh size can be adjusted to less state; With the continuous increase of yellow croaker fish body, can suitably increase the size of mesh.It should be noted that because inhomogeneous variation appears in fingerling growth in net cage, keep rational breeding density in net cage, still will sub-elect a part of fingerling cultivation in other net cages.This assorting room be take and the least possible moved case as principle, and mesh size is adjusted according to the fingerling size remaining in net cage.The structure of the present embodiment has been avoided the single limitation of bringing of net cage mesh, is applicable to each stage of yellow croaker cultivation, has reduced the amount of labour that whole fish bodies that the size variation by fish body causes move case, has improved largely the availability of net cage; And have advantages of simple in structure, manufacture easy, easy for installation.
Specific embodiment described herein only illustrates principle of the present utility model and effect thereof illustratively, but not for limiting the utility model.Any person skilled in the art person all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under in every case and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
