Multifunctional cabin combined artificial fish reef

Abstract

The invention discloses a multifunctional cabin combined artificial fish reef. The multifunctional cabin combined artificial fish reef comprises a lower quadrangular frustum pyramid main body, a middle support column and an upper umbrella-shaped structure, wherein each slope of the lower quadrangular frustum pyramid main body is provided with openings, the interior of the lower quadrangular frustum pyramid main body is divided into cabins by transverse and vertical partition plates, the cabins communicate through the openings, a part of cabins are a darkroom structure which not directly communicate with the outside, the umbrella-shaped structure is located above the quadrangular frustum pyramid main body and is fixedly connected with the quadrangular frustum pyramid main body through a connecting bolt on the middle supporting column, the umbrella-shaped structure is provided with an algae attachment base and an opening, the upper surface and the inclined surfaces of the quadrangular frustum pyramid main body are rough surfaces, and the upper surface of the top umbrella-shaped structure is a porous surface which is easy for algae attachment. The artificial fish reef has a shadow-rich structure, the multi-cabin structure can become a place for refuge, rest and spawning of various fishes, algae and invertebrate organisms are easy to attach to the porous plastid on the surface, the attachment density is high, and baits are provided for the fishes, sea cucumbers, abalones and the like.

Description

technical field [0001] The invention belongs to an underwater ecological artificial fish reef engineering facility, in particular to an artificial fish reef with a combination of multifunctional cabins. Background technique [0002] The ecosystem formed by artificial reefs has played a huge role in the improvement and restoration of sea habitats. Putting in artificial reefs can effectively protect juvenile fish and shrimps, improve their survival rate, and provide fish with a good habitat and feeding places , Contribute to the increase of resources doubling or dozens of times. my country has paid more and more attention to the construction of artificial reef ecosystems, and the national capital investment and construction scale have increased year by year. 110 national-level marine ranch demonstration areas have been approved and established. In the "Central No. 1 Document", it is clearly required to develop modern marine ranching and strengthen scientific and technological...

AI Technical Summary

Problems solved by technology

This type of reef has a rich surface area and good air permeability, which can be used by algae and invertebrates to attach and provide rich bait for sea cucumbers, abalones and other sea treasures. However, this type of reef has a simple structure and low technological content.

The tower-type fish reef has a large number of hollows, and the internal complex and hollow structure can have a significant impact on the flow field around the reef, which can produce complex flow field effects and effectively provide rich nutrients and nutrients for the surrounding reef. Bait, which can attract more reef fish to gather and migratory fish to inhabit, but its surface area is relatively small, which is not conducive to algae attachment

Some fishes and cephalopods have complicated spawning environment requirements, and like environments with less light, slow flow velocity, and high concealment. The internal space of the existing fish reef structure is more than the direct connection with the outside world, which is not conducive to the spawning of such animals. Therefore, the development structure Complicated, with a darkroom structure not directly connected to the outside, and with a large surface area, a multifunctional artificial reef suitable for algae attachment, marine treasure proliferation and fish collection is very necessary
