Technical Field

[0001] The invention relates to the technical field of fish reefs, and more particularly to an artificial fish reef for improving proliferation efficiency. Background Art

[0002] Artificial reefs are structures set up in the sea by humans. Their purpose is to improve the ecological environment of the sea area and create a good environment for marine life to live in, so that they can effectively increase the number of reefs in the sea area, avoid the small number of natural reefs affecting the normal survival and habitat of fish, and effectively improve the growth environment of fish; In summary, the inventors have found that the existing artificial reefs have the following main defects: since the current artificial reefs are solid as a whole or have only a few grooves, when fish spawn, the fish eggs will gather on the surface of the grooves of the reefs, and then because the grooves are exposed to the outside, the fish eggs are very likely to be carried away when the ocean current appears, and at the same time, they cannot help fish avoid attacks from other organisms. Therefore, it will be reflected that the current artificial reefs cannot meet the characteristics of improving proliferation efficiency, thereby reducing the use effect of artificial reefs.

[0019] 2. The present invention is a further improvement on the positioning shaft of the small protective door. The convex blocks of the parallel blocks can ensure that the intersecting vertical bodies are arranged in a straight line at the upper end of the limit frame. Then the connecting frame on the side of the lower end of the vertical body can determine the position of the rotating body through the magnetic block and the positioning sleeve, so that the parallel setting of the rotating body can ensure that the rotating rod can rotate at a fixed point in a stable straight line, avoiding tilting that affects the normal forward and backward pushing stability of the solid plate. Furthermore, the rotating body can prevent automatic falling off during cyclic use by cooperating with the top restraint block and the restraint frame of the balance block.

[0020] 3. The present invention is based on a frame added to the bottom layer of the protective cavity. The loading slots and positioning blocks in the frame allow the external bolts to be locked in a straight line, so that after one end of the rubber sheet clamps the force-bearing end of the positioning block, the bolts can position the rubber sheet at a precise position, ensuring that the rubber sheet can completely cover the surface of the bottom layer of the protective cavity, so that the rubber sheet can directly contact the fish eggs through its flexible characteristics, avoiding the rupture of the fish eggs due to the direct contact of the metal surface or other sharp areas without a protective cuticle layer on the surface, further ensuring that the fish eggs can develop stably in the protective cavity.
