Embodiment Construction

[0021] Such as figure 1 and figure 2 Shown, offshore floating rope type net cage system of the present invention comprises framework, net cage, anchor rope and iron anchor. The main cable 1 made of two submerged nylon ropes with a total breaking strength of 28,000 kg and the auxiliary cable 2 made of 20 polyvinyl chloride ropes are connected to form a frame with 10 cage openings and a spacing of 3.5m between the cage openings. , the main and auxiliary cables of the frame are bound with buoys 3 connected in series with buoy ropes and with a spacing of 42 cm, and a floating body 4 is respectively tied at the two ends of the main cables. The specification of cage 5 is 6m×6m×6m in length×width×depth. It is moderate in size and relatively convenient to manufacture and operate. It is made of 71mm nylon mesh, which is sewn with 53-thread nylon rope. . The net cages are bound at the mouth of each net cage in the frame, arranged in a single row, and the distance between groups is 6...

Abstract

The invention discloses an offshore drift line type net cage system. The system comprises a frame, net cages, anchor lines and iron anchors, wherein a main cable is connected with an auxiliary cable to form the frame, floats are bound on the main and auxiliary cables of the frame, two floats are separately bound on the two ends of the main cable; each net cage is bound at each net cage port in the frame, the net cages are arranged in single row and have 50-100m of group distance; the side rope and hanging rope of each net cage are bound on the corresponding positions of the main and auxiliary cables; the position near the central section of the net cover of the net cage is provided with a feeding opening, a float or floating body is bound at the feeding opening; the sinker of the net cage is bound on the bottom surface of the net cage and on the foot line of the position of the hanging rope; and the main anchor line is connected with the main iron anchor and the two ends of the main cable of the frame, and the auxiliary anchor line is connected with the auxiliary iron anchor and the main and auxiliary cables at the four corners of the net cage opening of the frame. The offshore drift line type net cage system has reasonable structure and layout, perfect supporting facilities, good wave and wind resistance, removable combination and convenient operation.

Description

technical field [0001] The invention relates to a net cage, in particular to an offshore floating rope type net cage system. Background technique [0002] Cage fish farming is the most important method of marine aquaculture and has very broad development prospects. However, the structure and layout of traditional cages are unreasonable, and the system is not complete. The frame is mainly processed with wood board or wood-mixed materials. Poor self-purification ability, serious self-pollution, low breeding efficiency and serious diseases. These problems have seriously restricted the sustainable development of marine cage culture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an offshore floating rope net cage system with reasonable structural layout, complete system matching, excellent wind and wave resistance performance, detachable assembly and easy operation. [0004] In order to solve the above technical ...
