Large-sized composite net enclosure

Abstract

The invention discloses a large-sized composite net enclosure and relates to fishery equipment. The large-sized composite net enclosure consists of reinforced concrete piles, channel steel, copper alloy woven nets, three-strand polyester ropes, ultrahigh-molecular-weight polyethylene fibers, ultrahigh-molecular-weight polyethylene warp knitted nets, polypropylene ropes, through-type floats, stainless steel pipes, high-density polyethylene sheets, lead core braided ropes and waste netting. The large-sized composite net enclosure is characterized in that pile piers are poured at the top ends of the reinforced concrete piles and the tops of two adjacent reinforced concrete pile piers are connected by using the channel steel; the netting is a composite netting structure with cylindrical durable netting with strengthening ropes, cylindrical longitudinal flexible connectors with strengthening ropes, cylindrical copper alloy braided nets with strengthening ropes and anti-escaping nets with strengthening ropes. The anti-escaping nets with the strengthening ropes in the composite netting and the 0.5m-high cylindrical copper alloy braided nets with the with strengthening ropes are put in an excavated trench and the S-twist three-strand polyester ropes on the composite netting are bound with the reinforced concrete piles; 1kg of waste netting is filled per meter of the trench around the net enclosure and then sand and soil are filled and compacted in the trench.

Description

technical field [0001] The invention relates to a composite fence for breeding in the field of fishery equipment and engineering technology. Background technique [0002] The existing net fence adopts a single variety of ordinary synthetic fiber net clothing, a single wire, and only simple anti-escape measures such as sinking are used between the net fence and the seabed. Both are directly tied and connected. The 15-strand polyethylene warp-knitted net is made of 2 loops and 9 weft-inserted synthetic fiber nets. The fiber strength utilization rate of the mesh matrix is ​​low, the net strength is also low, and the anti-ultraviolet aging ability is poor. The overall durability, anti-fouling performance, energy saving and consumption reduction performance and anti-escape measures are relatively poor, easy to wear and tear, short service life, continuous wear between the net clothes, net ropes and net poles, fish escape when the net is broken There are many accidents, and the ...

AI Technical Summary

Problems solved by technology

The 15-strand polyethylene warp-knitted net is made of 2 loops and 9 weft-inserted synthetic fiber nets. The fiber strength utilization rate of the mesh matrix is ​​low, the net strength is also low, and the anti-ultraviolet aging ability is poor. The overall durability, anti-fouling performance, energy saving and consumption reduction performance and anti-escape measures are relatively poor, easy to wear and tear, short service life, continuous wear between the net clothes, net ropes and net poles, fish escape when the net is broken There are many accidents, and the screen is changed every two years, and the cost of changing the screen is high

The net clothes and net poles are seriously attached by marine fouling organisms, resulting in poor water exchange inside and outside the net, and the long-term wear and tear between fouling organisms and net clothes, resulting in more frequent net changes and high labor intensity.

Changing nets or changing rods can easily cause emergency response of aquaculture objects, affect the normal growth and development of aquaculture objects, and affect the production cost and economic benefits of aquaculture

The wind resistance of the existing fence is poor, which can easily cause the fence to fall, and can only be suitable for a small enclosure area

Problems that have been exposed in the development of aquaculture net enclosures, such as poor wind and wave resistance of aquaculture net enclosures, small enclosure area, poor anti-marine biofouling performance, poor exchange of water inside and outside the enclosure, and fish escaping from the bottom of the enclosure The problem and the potential threat of the large consumption of raw materials for the net rope net are great, which seriously affects the efficiency of the net breeding. The exchange rate of water inside and outside the net clothes, reduce the number of net or pole changes for net farmers, reduce the consumption of raw materials for net rope nets, improve the comprehensive benefits of net nets, and improve the level of net facilities and equipment
