To consult accompanying drawing below and describe specific embodiments of the invention in detail.
Embodiment
At first see also first embodiment that Fig. 1 and Fig. 2 describe wind wave resistance net cage of the present invention.
Wind wave resistance net cage of the present invention can be divided into three parts on the whole: frame structure, dictyosome structure and anchoring structure.
Frame structure is positioned at the bottom of whole net cage, mainly is made of a horizontal annular member 11.Horizontal annular member 11 can be made polygon (as shown in this embodiment), and it can make other shape, for example circle etc.In the central authorities of horizontal annular member 11, be provided with an intermediate connecting ring 12, there are many framework ropes 13 to be connected between this intermediate connecting ring 12 and the horizontal annular member 11.In order to regulate the rate of tension of framework rope 13, can in the junction of framework rope 13, a screw thread spinner 14 be set as shown in Figure 3 with horizontal annular member 11, rotate the rate of tension that this screw thread spinner 14 can be regulated framework rope 13.
The dictyosome structure comprises level net 31, side direction net 32 and cover net 33.Level net 31 is arranged on the frame structure, forms the spacer screen part of dictyosome structure.In the present embodiment, the outer rim of level net 31 is connected on the horizontal annular member 11, and the middle inner edge of level net 31 is connected on the intermediate connecting ring 12 of frame structure, and level net 31 is fixed on the frame structure.Framework rope 13 provides the holder that makes progress power for level net 31.
The lower edge of side direction net 32 links to each other with frame structure with level net 31, and specifically, the lower edge of side direction net 32 is connected on the horizontal annular member 11, and extends upward, and forms the side mesh portions of dictyosome structure.
The upper limb of side direction net 32 links to each other with a cover net 33, is so formed the online of dictyosome structure by cover net 32, so forms the dictyosome structure of a sealing.In order to make dictyosome form a space, in the junction of side direction net 32, be provided with a plurality of floats 34 with cover net, after inserting net cage in the water, the buoyancy that float 34 produces upwards stretches side direction net 32 and cover net 33, and 31 on level net is with the frame structure submerged.
Anchor word structure includes a plurality of anchors 51.Anchor 51 is made by the bigger metal material of proportion usually.Each anchor 51 is connected on the frame structure by an anchor line 52, centre position at anchor line 52 connects a sea float 54 by float rope 53, this sea float 54 is across the sea floating, make anchor line 52 tensionings by float rope 53, thereby prevent frame structure, and even whole net cage drifts about in seawater.Being connected between float rope 53 and the anchor line 52 can be by a becket bridle 61.
So far describe the most basic structure of wind wave resistance net cage of the present invention, can reach the purpose with wind wave resistance and moisture resistance stream ability of the present invention.
Below description be further perfect to cage structure of the present invention.
As shown in Figure 1, the present invention can also set up supporting leg 14 lifting floating drums 15 on frame structure, and supporting leg 14 is installed in the bottom of frame structure, and the installation site of lifting floating drum 15 can be on horizontal annular member 11.The effect of lifting floating drum 14 can make the frame structure come-up or sink, and because of it belongs to known technology, therefore, in the present embodiment, launches narration no longer in detail.
In addition, feed intake for convenience, in the present embodiment, can also set up the courtyard 35 that feeds intake.The courtyard 35 that feeds intake can be made with Web materials, and its lower edge links to each other with cover net 33, and upper limb is provided with some water wings 36, so that the dog-house of the courtyard 35 that feeds intake floats on the water surface.
For anti-many waves and the moisture resistance stream ability that further improves the dictyosome structure,, can also set up cover net fake 55 and cover net float 56 for anchoring structure.Cover net float 56 links to each other with cover net fake 55 by rope, makes cover net rope Figure 55 remain on the top of cover net 33.Being connected between rope and the cover net fake 55 can be passed through a becket bridle 62.In addition, cover net fake 55 also is connected on the cover net 33 by rope.So, further improve whole dictyosome structure and improve wind wave resistance and moisture resistance stream ability.Preferably, between becket bridle 61 and becket bridle 62, also can be connected a rope 63.
See also second embodiment that Fig. 4 and Fig. 5 describe wind wave resistance net cage of the present invention below.
Compare with above-mentioned first embodiment, second embodiment has increased hierarchy, specifically changes mainly on frame structure.
As shown in Figure 4, compare with first embodiment, frame structure has increased the horizontal annular construction member 21A in a upper strata, is connected by a strut 25 between the horizontal annular construction member 21A in upper strata and the horizontal annular member 21.The lower layer of water plain net of on horizontal annular member 21, laying 41, on the horizontal annular construction member 21A in upper strata, also be equipped with upper water plain net 41A.By this structure, in that having been formed two in vertical direction, net cage of the present invention independently cultures the space.
Other parts in the present embodiment are basic identical or similar to first embodiment, so discuss no longer in detail at this.
