[0029] Embodiment 1

[0030] As shown in Figures 1 to 5 An artificial oyster reef structure includes a wave-damping base 1 and an upper reef body, the wave-damping base 1 and the upper reef body are floatingly connected, the height of the wave-damping base 1 is lower than the historical lowest water level, the wave-approaching surface of the wave-damping base 1 is inclined, the upper reef body includes a floating reef 2, and the floating reef 2 is provided with an oyster attachment structure 23.

[0031] The wave-damping base 1 of the application realizes wave damping on the seabed through the inclined wave-approaching surface, the oyster attachment structure 23 is arranged on the upper reef body to realize oyster growth and oyster reef formation, and since the upper reef body and the wave-damping base 1 are floatingly arranged, the upper reef body can float together with the wave-damping base 1 when the tidal level changes, so that the tidal level change can be adapted, and the generation efficiency of the oyster reef is stable.

[0032] The wave dissipating base 1 comprises a first base block 11 and a second base block 12 arranged in the rising tide direction in sequence, that is, compared with the first base block 11, the second base block 12 is closer to the shore. The maximum height of the second base block 12 is higher than that of the first base block 11. The wave dissipating effect is achieved by multiple layers. The first base block 11 is provided with multiple blocks, and the second base block 12 is also provided with multiple blocks. Adjacent first base blocks 11 are arranged at intervals, and adjacent second base blocks 12 are also arranged at intervals. The second base block 12 is arranged between two adjacent first base blocks 11 and simultaneously connects the two first base blocks 11. When the bottom wave rises with the tide, it first contacts the first base block 11, is then split by the interval between the first base block 11 and the adjacent first base block 11, and cooperates with the second base block 12, so that the wave dissipating effect is reliable.

[0033] In the embodiment, the cross-sectional shape of the first base block 11 is arc-shaped, and the cross-sectional shape of the second base block 12 is arc-shaped. The lower part of the first base block 11 and the second base block 12 can be used as a breeding space for oysters. The wave-approaching side of the first base block 11 and the second base block 12 is arc-shaped to form an inclined wave dissipating structure. One end of the second base block 12 is fixedly connected to the upper side of the first base block 11. Specifically, one end of the second base block 12 is provided with a plug-in strip 13, and the first base block 11 is provided with a plug-in groove 14, and the plug-in strip 13 and the plug-in groove 14 are plugged. The first base block 11 and the second base block 12 are matched by the plug-in strip 13 and the plug-in groove 14, have high integrity, and the overall structure of the wave dissipating base 1 is reliable and high. The end of the second base block 12 away from the first base block 11 is provided with a fixing block 10. The fixing block 10 increases the stability of the arrangement of the second base block 12. In addition to being used as a wave dissipating structure, the first base block 11 and the second base block 12 are also used as a counterweight for the lower part of the oyster reef as a whole, and are made of materials with high density such as bricks, stones and metals.

[0034] The upper reef body is a forming part of the reef body, and the upper reef body floats or suspends in the water body above the wave dissipating base 1. The upper reef body comprises a plurality of floating reef bodies 2 and a connecting assembly connecting adjacent floating reef bodies 2. The floating reef body 2 comprises a body 21 and an internal hollow floating cylinder 22. The floating cylinder 22 is closed at both ends and hollow inside, and has a density less than that of the water body and a large buoyancy. The body 21 is fixedly arranged outside the floating cylinder 22. In order to prolong the service life of the floating cylinder 22, the floating cylinder 22 is made of plastic material. The body 21 is made of concrete and is formed by pouring outside the floating cylinder 22. The floating cylinder 22 extends radially outside with a rib to improve the combination of the body 21 and the floating cylinder 22. An oyster attachment structure 23 is arranged outside the body 21.

[0035] The connecting assembly is rotationally connected with a connecting ring 24, and the connecting ring 24 is connected with the wave-eliminating base 1 through a chain 25. The chain 25 is connected on the upper side of the fixed block 10. The rotation of the connecting ring 24 and the connecting assembly is arranged so that the upper reef body can rotate when the tidal level changes and the buoyancy changes, and each side of the upper reef body can be used for oyster climbing and survival. The connecting mode of the chain 25 makes the height of the upper reef body not fixed, and the upper reef body can better cooperate with the tidal level change and the buoyancy action to rise and fall.

[0036] The connecting assembly comprises a connecting shaft 26 and connecting chains 27 located at both ends of the connecting shaft 26, and the connecting chains 27 are connected with the buoyant tube 22. The connecting assembly connected with the adjacent floating reef body 2 comprises the connecting chains 27, and the distance between the adjacent floating reef bodies 2 can fluctuate with the water wave or can relatively rotate, thereby reducing the stress of the connecting assembly caused by the buoyancy.

[0037] In the embodiment, the outer profile shape of the cross section of the body 21 is a circularly-angled equilateral triangle, the oyster attachment structure 23 is an alloy cage or a net bag, one end of the oyster attachment structure 23 is hung or rotationally connected on the arc surface corresponding to the circular angle of the body 21, and the other end of the oyster attachment structure 23 is detachably clamped on the arc surface corresponding to the circular angle of the body 21. The clamping can be achieved by clamping the teeth or clamping blocks into the clamping grooves on the surface of the body 21. Each of the three sides of the body 21 corresponds to an independent net bag. The oysters can survive on the body 21 through the oyster attachment structure 23, and the number of oysters on the wave-encountering surface of the body 21 is more than that on the other surfaces. In the process of continuous climbing of the oysters, the initial wave-encountering surface 28 of the body rotates to be downward, that is, the state shown in Figure 1 When the oysters are too many or grow larger, the clamping position of the oyster attachment structure 29 on the initial wave-encountering surface is detached to be connected with the body 21 at only one end, the gravity of the oyster attachment structure drives the body 21 to rotate, and the state shown in Figure 5 is formed, that is, the remaining two surfaces are wave-encountering, the wave-encountering surface 30 located below is downwardly inclined and has a large wave-encountering area, the wave-encountering surface 31 located above is upwardly inclined and has a smaller inclination angle, and when the oysters on the wave-encountering surface located below increase, the body further rotates to increase the wave-encountering area of the wave-encountering surface located below. When the oysters on the wave-encountering surface located below further increase, the oyster attachment structure 32 on the wave-encountering surface located below also detaches to further drive the body to rotate. At this time, the wave-encountering area on the wave-encountering surface located above reaches the maximum, so that each side of the body 21 has the opportunity to be wave-encountering, and most of the sides of the body 21 can climb more oysters. The utilization rate of the floating reef body 2 is high, the oyster reef forming efficiency is stable, and the situation that only one side of the floating reef body 2 climbs oysters and causes a large stress on the connection part between the adjacent floating reef bodies 2 to be damaged does not occur.

[0038] As a simple replacement of the above scheme, the outer profile shape of the cross section of the body 21 can be a circularly-angled square or a pentagon.
