A seaside nuclear power plant water intake hairy shrimp interception net

Abstract

The invention discloses a net for intercepting hairy shrimp at a water intake of a coastal nuclear power plant, comprising: several mesh bags and a collection bag arranged at the tail of the mesh bags; several mesh bags are arranged side by side, and adjacent mesh bags cooperate with each other connected, the end of the mesh bag is provided with a mesh port, one side of the edge of the mesh port is provided with a sinker ring, and a number of buoys are arranged on the side symmetrical to the sinker ring at the edge of the mesh port; any There is at least one inner bag inside the mesh bag, and when there are multiple inner bags, the plurality of inner bags are distributed at intervals along the direction from the mesh mouth to the collection bag, and both the mesh bag and the inner bag are arranged There are several mesh holes, and the mesh size of the plurality of inner bags is distributed in a gradient along the direction from the mesh mouth to the collection bag; at least one pull rope is arranged on the mesh bag, and the pull rope is used to fix the mesh bag, At least one floating ball is arranged on the collection bag.

Description

technical field [0001] The invention relates to a stretch net for intercepting hairy shrimp, in particular to a stretching net for intercepting hairy shrimp at a water intake of a coastal nuclear power plant. Background technique [0002] In recent years, due to the change of fishery resources, the decline of large carnivorous fish resources, the reduction of natural enemies and many other objective reasons, the resources of hairy shrimp have been at the peak of reproduction and growth in recent years, which has promoted the development of the fishery of hairy shrimp. As far as the fishing of hairy shrimp is concerned, the fishing efficiency of hairy shrimp is high, the selectivity is strong, and it has strong mobility. At the water intake of some nuclear power plants, the hairy shrimp can be intercepted by setting the hairy shrimp net. Hairy shrimp is a plankton. The large zooplankton in the taxa are widely distributed in the Indian Ocean, the Pacific Ocean and the Atlantic...

AI Technical Summary

Problems solved by technology

However, due to the extremely small size of the prawns, the technical parameters of the nets for catching the prawns have very high requirements. Marine organisms are fished together, destroying the existing food chain, but also affecting the reproduction of other marine organisms, which greatly affects marine biological resources and the sea environment
