Multifunctional floatable and submergeable reef

Abstract

The invention discloses a multifunctional floatable and submergeable reef which comprises a floating substrate and a sinking substrate. A ball float is arranged outside the floating substrate. The floating substrate is internally provided with an upper chamber and a lower chamber which are isolated from each other. The upper chamber of the floating substrate is internally provided with a reel for winding a rope. A plurality of expanding bases which are parallelly arranged in the vertical direction are arranged below the folating substrate. A disengaging mechanism for realizing separation between the expanding bases and the floating substrate in a one-by-one manner is arranged between the floating substrate and the expanding bases. A plurality of alga culturing bricks are arranged above the sinking substrate. The sinking substrate is connected with the floating substrate through a rope. The rope penetrates through the middle part of each expanding base. The sinking substrate comprises an upper board and a lower board. A plurality of supporting rods are fixed between the upper board and the lower board. The invention aims to provide the multifunctional floatable and submergeable reef which has advantages of realizing reasonable structure and multiple functions, providing food for fish swarms and realizing a good protecting effect.

Description

technical field [0001] The invention belongs to the field of marine life development, in particular to a multifunctional floating fish reef. Background technique [0002] In the marine biological industry, fish multiplication and seaweed multiplication are the mainstream directions at present. In marine fisheries, various fish gathering devices such as artificial reefs will be used to attract and protect fish schools. To achieve fish gathering; in terms of seaweed proliferation, at present, seaweed reefs are mainly used as units to establish seaweed farms with a certain area to provide a good basis for seaweed attachment and proliferation. However, in the prior art, it is inconvenient to put and set fish reefs and algae reefs. This is because most of the fish reefs need to sink to the bottom (sea bottom) or close to the bottom of the sea, but after the fish reefs are placed, the primary fish gathering effect is poor, and it is difficult to form a good micro-ecosystem on th...

Problems solved by technology

However, in the prior art, it is inconvenient to place and set fish reefs and algae reefs.

This is because most of the fish reefs need to sink to the bottom (sea bottom) or close to the bottom of the sea, but after the fish reefs are placed, the primary fish gathering effect is poor, and it is difficult to form a good micro-ecosystem on the bottom of the sea; algae reefs can provide more food for fish schools source, but because many seaweeds (especially artificially propagated seaweeds, such as sargassum and sargassum, etc.) grow relatively fast near the sea surface (intertidal zone, within tens of meters under the sea, etc.), on the seabed due to light exposure Poor and slow growth, so the algae reefs are usually placed closer to the sea surface, but it is difficult to provide good protection for fish schools near the sea surface, so the best fish gathering effect cannot be achieved
