Embodiment Construction

[0032] see figure 1 , figure 1 A schematic diagram of the three-dimensional structure of a cross-wing artificial fish reef according to the first embodiment of the present invention is disclosed.

[0033] In the present embodiment, the cross-wing artificial reef body (1) is made up of a three-dimensional frame, and the three-dimensional frame includes a main frame 10 and an auxiliary airfoil frame 11 extending outward from the main frame, an auxiliary airfoil frame 12, an auxiliary wing Shaped frame 13 and auxiliary airfoil frame 14 are formed; The base plate 15 that offers circular hole on the bottom surface of main body frame 10. The length and width of the main frame can be equal, and the extended length of the auxiliary airfoil frame can be 0.5 times of the length or width of the main frame. The height of the reef can be adjusted according to the substrate and hydrodynamic conditions, etc., and it is advisable not to exceed 1.5 times the length or width of the main frame...

Abstract

The present invention discloses a cruciform-winged artificial fish reef constituted by a space frame. The space frame comprises a main body frame and auxiliary winged frames extending outwardly from the main body frame. Plates with round holes are mounted, in whole or in part, on the main body frame and the auxiliary winged frames.The cruciform-winged artificial fish reef mainly has the followingadvantages: optimization and choice are made between the dead weight and the structure of the reef according to the hydrodynamic and bottom carrying capability conditions of a sea area, and a free choice can be made on whether bottom, side and top plates are arranged in whole or in part; and four semi-enclosed effective space structures are formed at two-wing joint parts of the main body frame, sothat the effective space cube of the cruciform reef is close to the volume of an octagon column. In a particular flow direction, at least 2 or 3 two-wing joint part structures can be deemed to be back flow regions, leading to an increase of 10-15% in effective space cube volume and facilitating hiding of marine life; thus, the space for marine life to swim around in the reef is expanded. The mainbody has suitable space and can serve as a marine habitat and a spawning and feeding ground. As a result, the productivity of a local marine ecosystem can be improved.

Description

[0001] field of study: [0002] The invention relates to the technical field of fishery infrastructure construction, in particular to a technology for improving the habitat of marine organisms and the ecological environment of the sea area with a reinforced concrete frame structure type fish reef, which is used to restore the marine ecological environment and restore offshore fishery resources, thereby A small artificial ecosystem that is extremely active and productive is formed. Background technique: [0003] Artificial reefs are placed in the ocean, which is conducive to the restoration of the marine ecological environment and the recovery of offshore fishery resources. By placing artificial reefs, it can provide a substrate for the attachment and growth of algae, increase spatial heterogeneity, and restore or improve the damaged ecological environment. By rebuilding the habitat of seabed organisms, a dominant population of island-reef benthic organisms will be formed in a...
