Embodiment Construction

[0035] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0036] Such as figure 1 As shown, a fish and algae reef for preventing wind and waves includes: a fish reef body 4, the fish reef body sinks to the bottom of the sea; and an algae reef body suspended in water, the buoyancy of the algae reef body is greater than gravity.

[0037] The reef body is made of concrete. The top of the fish reef body is provided with a connecting ring 4.1. A shelter cavity 4.2 is provided in the fish reef body. The outer surface of the fish reef body is provided with a connecting channel 4.3 communicating with the inner cavity of the shelter.

[0038] The algae reef body includes an algae reef frame body 1, several algae attachment structures 1.1 arranged on the algae reef frame body, several buoyancy devices 2 arranged on the algae reef frame body, a supporting floating frame 3 located directly below the algae reef ...

Abstract

The invention provides a wind and wave preventing fish and alga reef. The wind and wave preventing fish and alga reef has no high requirement for the transparency of sea water in a sea area and can effectively solve the problem that an alga reef floats along with waves on a sea surface and thus damages the growth on the alga reef. The wind and wave preventing fish and alga reef comprises a fish reef body which sinks to a seabed and an alga reef body suspended in water. The buoyancy of the alga reef body is greater than the gravity and the alga reef body is connected with the fish reef body via a connecting rope. The alga reef body comprises an alga reef rack body and a plurality of alga attachment structures arranged on the alga reef rack body. Each alga attachment structure comprises a vertical installing rod arranged on the alga reef rack body, a spherical alga reef rack with an upward opening and a plurality of alga attachment bases arranged on the spherical alga reef rack, wherein the spherical alga reef rack is provided with a vertical installing sleeve matching the vertical installing rod and is installed on the corresponding vertical installing rod via the vertical installing sleeve, and the vertical installing rod is also provided with a locking nut used for locking the vertical installing sleeve.

Description

technical field [0001] The invention relates to the field of shellfish culture, in particular to a storm-proof fish and algae reef. Background technique [0002] Affected by changes in the near-shore marine environment, the transparency of seawater has decreased, the sediment on the attachment base of near-shore rock reefs has increased, the habitat of seaweed is covered by a large number of low coral algae that can adapt to environmental changes, and the near-shore rock reef matrix has a large slope. , leading to the gradual reduction of the space suitable for seaweed habitat. [0003] The current artificial algae reefs are roughly divided into two categories: one is sunken algae reefs, which have very high requirements for the transparency of seawater in sea areas, otherwise it is difficult for seaweeds to obtain suitable light conditions; and they are easily covered by sediments; 2. Floating algae reefs (floating on the sea surface by floating balls, suspending the algae...
