Problems solved by technology

However, when changing the net clothes, cleaning the net clothes or pulling the net to collect fish, divers need to dive to the bottom to pull the sinker out of the water before collecting the net, or take out the support ring, which increases the labor time and thus increases the breeding cost. and low work efficiency

Embodiment 1

[0056] Embodiment 1: as Figure 2~Figure 12 As shown, two bolt holes 7 are arranged on the connecting plates at both ends of the arc-shaped metal rod 4 , and a collar 6 is welded to the inner middle part of the arc-shaped metal rod 4 . The fan-shaped arc of the arc-shaped metal rod 4 is 90°, and the four arc-shaped metal rods 4 are fixedly connected to each other from the end to form a closed circular ring, such as Figure 5 shown. The length of the sleeve pipe 10 is about 1 / 4 of the depth of the net clothing, so the proposed device uses 16 arc-shaped metal rods 4, 16 sleeve pipes 10 and 4 steel wire ropes 9 in total, as Figure 6 shown. The structure diagram of the proposed device and the net cage after installation is as follows: Figure 10 shown.

Embodiment 2

[0057] Embodiment 2: Three bolt holes 7 are arranged on the connecting plates at both ends of the arc-shaped metal rod 4 , and a collar 6 is welded in the middle of the inner side of the arc-shaped metal rod 4 . The fan-shaped radian of the arc-shaped metal rod 4 is 45°, and the eight arc-shaped metal rods 4 are fixedly connected from end to end to form a closed circular ring. The length of the sleeve pipe 10 is about 1 / 3 of the depth of the net, so the proposed device uses 24 arc-shaped metal rods 4, 24 sleeve pipes 10 and 8 steel wire ropes 9 in total.

[0058] According to the above ideas, more embodiments can be derived, which are not exhaustive here.

Abstract

The invention discloses a netting fixing device embedded inside a circular floating net cage. The netting fixing device includes arc metal rods, wire ropes and casing pipes; the two ends and middle inner side of each arc metal rod are each provided with a connecting plate and a sleeve ring, and the multiple arc metal rods are fixedly connected through the connecting plates in a head-tail mode to form a circular ring; within the depth range of a netting, multiple circular rings formed by the arc metal rods are arranged at intervals from top to bottom, firstly, all the sleeve rings of the bottomcircular ring are each moored and tied with a wire rope, and the bottom circular ring is sunk into the water body inside the net cage through the wire ropes; then, the wire ropes are sleeved with thecasing pipes and the upper circular rings in an alternate mode; finally, each wire rope is straightened and fixedly tied to the frame of the net cage. The netting fixing device has the advantages ofa simple structure, light mass, less material consumption, high strength and low overall costs, and can effectively reduce the volume loss rate of the netting, and installation and disassembly are convenient.

Description

Technical field: [0001] The invention relates to a seawater culture net cage, and more particularly relates to a net fixing device embedded in a circular floating net cage. Background technique: [0002] The cylindrical shape surrounded by the circular frame and the net clothing, and the cage floating on the water surface are called circular floating cages. In my country, the most widely used circular floating cages are HDPE frame circular floating cages, whose circumference is usually 40-100m, and gradually develop large deep-water cages with a circumference of more than 100m, which belong to the Large-scale deep-water cages in open or semi-open sea areas are the main development direction of seawater cage culture in the future. The structure of the circular floating net cage is as follows figure 1 shown. [0003] The net clothing system in the net cage is mainly to surround a cultured water body for the activities of cultured fish. If the seawater flow rate is fast, the...
