Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1:

an artificial algal reef suitable for a shallow sea area is hereinafter referred to as an artificial algal reef and comprises a reef body 1, wherein the reef body 1 is cylindrical and is made of materials such as coal ash and shells, the artificial algal reef has a rich void structure and is suitable for attached propagation of algae. A plurality of connecting belts 3 are fixed on the circumferential surface of the reef body 1, and the end parts of the connecting belts 3 are fixed with safety hooks 4. When the algal reef is constructed, the safe hooks 4 of the adjacent reefs 1 are hooked, so that the reefs 1 in the same area are connected into a whole, and the reefs 1 have stronger capability of resisting ocean current impact.

Example 2:

an artificial algal reef suitable for a shallow sea area, hereinafter referred to as an artificial algal reef, is different from embodiment 1 in that a plurality of protrusions 11 are provided on the surface of a reef body 1. The attachment area of the algae on the surface of the reef body 1 can be increased through the arrangement of the bulges 11. The algae attached to the protrusions 11 in unit area is more than the surface of the reef body 1, mainly because the water flow velocity of the protrusions 11 is large, the algae growth is not influenced by the floating mud accumulation. The algae-feeding animals gathered on the protrusions 11 are few, so that the harm to algae is small, the roots of the algae have enough space stretch in the protrusions 11, the attachment is firmer, and the influence of sea wave impact on the algae can be reduced.

The artificial algal reef further comprises a base 2, the base 2 is made of metal materials such as cast iron, and the surface of the artificial algal reef is subjected to corrosion-resistant treatment such as electroplating and paint spraying. The base 2 is of a frustum shape with the cross section gradually increasing from top to bottom. The upper surface of the base 2 is provided with a positioning groove 21 for placing and positioning the reef body 1. When the artificial algal reef is constructed, the reef body 1 is placed in the positioning groove 21 of the base 2, the reef body 1 is positioned through the positioning groove 21, and the supporting area of the reef body 1 is increased through the base 2, so that the reef body 1 is not easily taken away by ocean currents when placed on the seabed. The reef body 1 is arranged to be cylindrical, the base 2 is arranged to be frustum-shaped, ocean currents are easy to generate streaming when encountering the reef body 1 and the base 2, and the impact on the reef body 1 and the base 2 is small. At least three rings 5 are fixed on the circumferential surface of the base 2, and the rings 5 are uniformly distributed in the circumferential direction around the axis of the base 2. Through rings 5's setting, and then when removing and laying base 2, hoist and mount base 2 through lifting device to it is more convenient to remove and lay base 2.

The bottom surface of the base 2 is provided with a lightening groove 22. The weight reduction grooves 22 enable the base 2 to have lighter weight on the basis of keeping the supporting area, and enable workers to operate the base 2 more conveniently. The peripheral wall of the base 2 is provided with a positioning pin 6 arranged along the radial direction of the base 2; the positioning pin 6 axially penetrates through the peripheral wall of the positioning groove 21 and the positioning pin 6 is slidably connected with the base 2 in the axial direction thereof. The circumferential surface of the reef body 1 is provided with a positioning hole 12 for being inserted with the positioning pin 6. After the reef body 1 is placed in the positioning groove 21, the positioning hole 12 on the circumferential surface of the reef body 1 is aligned with the positioning pin 6, and then the positioning pin 6 is slid, and the positioning pin 6 is inserted into the positioning hole 12. The reef body 1 is limited by the insertion of the positioning pin 6 and the positioning hole 12, so that the reef body 1 is prevented from being separated from the positioning groove 21.
