Problems solved by technology

[0003] The current algae reefs can be roughly divided into two categories: one is the sunken algae reef, which has very high requirements on the transparency of seawater in the sea area, otherwise it is difficult for the algae to obtain suitable light conditions; the other is the floating algae reef (through The floating ball floats on the sea surface, suspending the algae reef in the seawater), this kind of floating algae reef is not only greatly affected by the sea surface waves, but also easily damages the algae growing on the algae reef due to the floating of the sea surface; The ball floating on the sea will also block the sunlight and affect the light conditions of the seaweed

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0033] Such as figure 1 As shown, a fish and algae composite reef device that rises and falls with the tide level includes: a fish reef body 1, the fish reef body sinks to the bottom of the sea; an algae reef body 2 suspended in water, the buoyancy of the algae reef body is greater than gravity; The tide level on the fish reef body is self-elevating regulating mechanism 3. The reef body is made of concrete. A shelter inner cavity 1.1 is provided in the fish reef body, and a connecting channel 1.2 communicating with the shelter inner cavity is provided on the outer surface of the fish reef body.

[0034] The algae reef body includes the algae reef frame 2.1 and the buoyancy block 2.2 arranged on the algae reef frame. Several seaweed attachment bases are arranged on the algae reef frame. Seaweed is transplanted on the seaweed attachment base. ...

Abstract

The invention discloses a fish and seaweed composite reef device elevating with sea level. An objective of the invention is to provide a fish and seaweed composite reef device which is not influenced by waves of sea and can elevate with sea level, so seaweed obtain appropriate light condition. The device comprises a fish reef body, an algal reef body suspended in water, and a sea level self-elevating adjusting mechanism arranged on the fish reef body. The sea level self-elevating adjusting mechanism comprises a connecting rope, a main cylinder whose axis extends up and down, a main piston body arranged in the main cylinder, an adjusting cylinder whose axis extends up and down, and an adjusting piston arranged in the adjusting cylinder. The inner diameter of the main cylinder is larger than the inner diameter of the adjusting cylinder. The main cylinder is internally provided with a pre-tightening compression spring between the upper end of the main cylinder and the main piston body. The lower opening of the adjusting cylinder is communicated with the inner cavity of the main cylinder. One end of the connecting rope is connected with the algal reef body, and the other end of the connecting rope is connected with the adjusting piston.

Description

technical field [0001] The invention relates to a fish and algae composite reef, in particular to a fish and algae composite reef device that rises and falls with the tide level. Background technique [0002] Affected by changes in the near-shore marine environment, the transparency of seawater has decreased, the sediments on the attachment base of near-shore rock reefs have increased, the habitat of large seaweeds has been covered by a large number of low coral algae that can adapt to environmental changes, and the near-shore rock reefs have a large slope. As a result, the space suitable for macroalgae habitat gradually shrinks. [0003] The current algae reefs can be roughly divided into two categories: one is the sunken algae reef, which has very high requirements on the transparency of seawater in the sea area, otherwise it is difficult for the algae to obtain suitable light conditions; the other is the floating algae reef (through The floating ball floats on the sea su...
