Abstract

The utility model provides the aquatic equipment of the net box for fishery, which is mainly composed of a floating frame, a supporting rod, a draw rod, an upper suspension ring and a lower suspension ring. In the manufacture and the use, the utility model has the advantages of convenient material source, stable box shape which ensures the use area, difficult damage of the fish body, convenient box lowering placement and box lifting, etc.

Description

Net box frame for fishery

The utility model belongs to the aquaculture equipment class.

Utilize the mode of fish culture in net pen now comparatively universal, its capital equipment of breeding fish is, the iron tank tower that has float is installed at the net cage oral area, net cage hangs with heavy stone for four jiaos, and four limits are equipped with sinker at the bottom of the net cage, and the employed float of this form, sinker are more, and it is bigger to make that material expends, particularly have an outstanding shortcoming to be, easily do not guaranteed usable floor area by the stormy waves blastic deformation at the bottom of the case, the etting that fish is deformed swathes and causes damage, death again.

The purpose of this utility model is at the yielding shortcoming of net cage in the above-mentioned use, and the equipment that provides cocoa that net cage can be fixed.

Structure of the present utility model is, four jiaos at scaffold are equipped with pole respectively, and are added with pull bar and make pole reinforce, and are equipped with upper lift ring in the pole upper end, the lower end is equipped with lower lift ring, net cage is individually fixed on the upper and lower suspension ring for four jiaos, and the utility model purpose is achieved.

The utlity model has draw materials conveniently, the stable usable floor area that guarantees of box-shaped, advantage such as fish body not easy damaged is hindered, and nowel, suitcase are convenient.
