Detailed Description
The invention will be further described with reference to the accompanying drawings.
Fig. 1, 2 and 3 show an adjustable deep sea cage culture system using offshore wind power jacket foundation. Offshore wind power jacket basis sets up platform 1 including jacket 4 top, and a tower section of thick bamboo 3 supports 2 through the pipe chute and is connected with platform 1, adopts bracing 42 to connect four spinal branch posts 41, sets up box with a net farming systems on the jacket 4. The net cage culture system adopts a bottom net structure 7, a side net 5, a side net cable 6 and a floating net structure 8 to form a culture area.
The bottom net structure 7 is provided with an inner bottom net 71 and an outer bottom net 72 respectively on the inner side and the outer side of the jacket 4, an outer bottom net outer ring rope 75 is arranged on the outer ring of the outer bottom net 72, an outer bottom net inner ring rope 76 is arranged on the inner ring, and the outer bottom net inner ring rope 76 is fixedly connected between two adjacent struts 41; the bottom of the inner bottom net 71 is provided with crossed inner bottom net cables 73, and two ends of each inner bottom net cable 73 are fixedly connected to two diagonal struts 41; an outer bottom net cable 74 is arranged at the bottom of the outer bottom net 72, one end of the outer bottom net cable 74 is fixedly connected to the jacket 4, and the other end is connected to an outer bottom net outer ring rope 75 through a bottom net knot 77.
The outer ring floats 83 are arranged on the outer ring rope 82 at equal intervals on the outer ring 81 of the floating net structure 8, the radial rope 84 penetrates through a hard pipe fixed with the equal-interval radial floats 85, one end of the radial rope 84 is connected to the outer ring rope 82 through a floating net rope knot 86, the other end of the radial rope 84 is connected with the lower ends of the inner ring rope 87 and the winch rope 91 which are arranged on the outer side of the strut 41 to form a hoisting rope knot 88, and the upper end of the winch rope 91 is connected with the winch 9.
The outer float 83 and the radial float 85 are tubular or spherical structures. The hoist 9 is driven manually or electrically.
By adopting the technical scheme, the radial rope 84 penetrates through the hard pipe fixed with the radial floats 85 at equal intervals, and the float outer ring 81 supporting the floating net structure 8 cannot float to the position near the jacket 4 due to wind and waves, so that the culture area formed by the bottom net structure 7, the side net 5, the side net cable 6 and the floating net structure 8 is reduced. Normal weather can maintain the maximum breeding area shown in fig. 4.
If severe sea conditions such as typhoon, heavy wave and the like are met, the inner ring ropes 87 and the radial ropes 84 connected with the hoisting ropes 88 can be hoisted out of the water surface slowly by simultaneously tightening the hoisting ropes 91 of the four hoists 9 arranged on the platform 1, and the water outlet state of the radial ropes 84 is in an inclined state due to the fact that the radial ropes 84 are sleeved with hard pipes, as shown in fig. 5. The four winches 9 continue to operate, leaving the radial lines 84 entirely out of the water, in a vertical position, leaving the lateral nets 5 partly or entirely out of the water, and the floats entirely out of the water, as shown in figure 6. The farm is then retracted to the area near the jacket 4. After the sea state returns to normal, the winch 9 releases the winch rope 91, so that the culture area returns to the state shown in fig. 4.
The winch 9 can be driven manually or electrically, so that the reliability of net collection and net release is improved.
