Embodiment 1

[0022] Such as Figure 1~3 As shown, the pile net separation type large-scale shallow sea seine culture device includes a seine net 8, an auxiliary floating ball 4 connected to the surface of the seine net 8, a post pile 3 connected with the purse net 8, and the top of the purse net 8 is connected with the post post 3 , the bottom of the fence 8 is connected with a fixed pile 9 and a sinker block 10, the auxiliary floating ball 4 on the surface of the fence 8 is connected with the main floating ball 2, and the main floating ball 2 is connected with the anchor pile 7.

[0023] In the present invention, the column pile 3 and the fence 8 are separated, which can better reduce the direct force of the net clothes in the water under the action of waves and tidal currents, and give full play to the flexibility of the fence 8. Through the fixed pile 9 and sinking The bottom block 10 closely fits the bottom of the seine net 8 to the seabed 5, which can effectively prevent the cultured ...

Embodiment 2

[0032] Such as Figure 1~3Shown, pile-net separation type large-scale shallow sea purse seine cultivation device, comprises purse seine 8, the sub-float 4 that the surface of purse-seine 8 is connected, and sub-float 4 is connected at the preferred 5 / 10 place of purse-seine 8 total length, and purse-seine 8 The post pile 3 connected with the net 8, the top of the fence 8 is connected with the post pile 3, the top of the fence 8 and the post pile 3 are connected with a clamp 301, the clamp 301 is higher than the high tide water level 1, and the clamp 301 is connected with the post pile 3 The outer diameter ratio is preferably 1.1:1, the angle between the fence 8 and the column pile 3 is preferably 45°, the bottom of the fence 8 is connected with a fixed pile 9 and a sinking block 10, and the sinking block 10 is a metal block or a cement block Or ceramic blocks or stones, the auxiliary floating ball 4 on the surface of the fence 8 is connected with the main floating ball 2 throu...

Abstract

The invention provides a pile and net separated large-scale shallow sea purse net culture device. The culture device comprises a purse net, an assistant floating ball connected to the surface of the purse net and a column pile connected with the purse net, wherein the top end of the purse net is connected with the column pile, a fixing pile and a sinking block are connected to the bottom of the purse net, the assistant floating ball on the surface of the purse net is connected with a main floating ball, and the main floating ball is connected with an anchor pile. By adopting the column pile and purse net separated structure, direct stress on the net in water under the action of waves and tides can be well reduced, and the flexibility of the purse net can be fully exerted; the bottom end of the purse net is tightly attached to the sea bed through the fixing pile and the sinking block, cultured fishes can be effectively prevented from escaping, and the manufacturing cost of the culture device is reduced; stress on the purse net in the water is further regulated through the main floating ball and the assistant floating ball, the flexibility of the purse net is exerted to the greatest degree, and thus the culture device can adapt to the harsh and complex marine environment.

Description

technical field [0001] The invention belongs to the technical field of purse seine culture, and in particular relates to a large-scale shallow sea purse seine culture device with separated piles and nets. Background technique [0002] Shallow sea seine aquaculture engineering technology is a new concept of ecological marine aquaculture, and it is a new important development trend of marine aquaculture in the future. The seine breeding area is large, the effective breeding volume is also large, and the unit cost is low. In my country, the effective breeding volume of a single deep-water cage is generally 1000~1500m 3 , while the deep-water seine aquaculture water body is far larger than the deep-water cages, which can be as high as hundreds of thousands of square meters, which is equivalent to hundreds of deep-water cages. Both the overall cost and the unit volume engineering cost are far lower than deep-water cages. [0003] The breeding objects have a large space for acti...
