Description

Technical Field

[0001] The invention relates to the technical field of oyster reef ecological restoration, in particular to a wave-breaking oyster reef structure that is self-adaptive to tidal fluctuations. Background Art

[0002] Under the pressure of active human activities and changes in natural conditions, many coastal areas are facing problems such as shoreline erosion and siltation, seawater pollution and habitat degradation. Against the background of coastal habitat degradation, the habitat of reefs is gradually lost, and the stability of the coastline and the self-purification capacity of seawater quality are further reduced, entering a vicious cycle. It is necessary to artificially improve the environmental conditions of the intertidal zone and nearshore shallow sea areas, and build a diverse ecosystem dominated by filter-feeding shellfish. Shellfish can gather and grow in large numbers to form reefs to eliminate waves and protect the coastline, forming a unique habitat and providing a habitat for other invertebrates and fish. As a filter-feeding animal, it also has important functions such as improving water quality. The existing plans and measures mainly include the placement of structures and substrates for shellfish to attach, the supplementation of filter-feeding shellfish for artificial seedling cultivation, and the planting of seagrass beds.

[0003] For example, in Chinese patent literature, patent number CN2023210251640 disclosed on November 21, 2023, discloses a hollow gentle slope bridge-type oyster gravel reef, including an oyster reef, the oyster reef including a left end and a right end which are symmetrically arranged on the left and right sides, the left end and the right end have the same structure, and both the left end and the right end are hollow metal parts, the hollow metal parts include two metal frames with trapezoidal structures, the metal frames include an upper metal frame and a lower metal frame, the upper metal frame located at the left end and the upper metal frame located at the right end are connected and fixed; the hollow metal parts also include a first support frame and a second support frame with a triangular structure, the first support frame is fixed to the hypotenuse of the lower metal frame, and the second metal frame is fixed to the bottom edge of the lower metal frame, the hollow metal frame also includes a rectangular frame, the rectangular frame is arranged in contact with the first support frame, the upper metal frame and the second support frame located at the left end and the upper metal frame and the second support frame located at the right end surround a vortex channel; the top surface of the upper metal frame, the top surface of the lower metal part and the top surface of the rectangular frame are all paved with gravel.

[0004] The shortcomings of the existing technology are that it cannot adapt to changes in water levels, and there is a situation where oysters lack water and the construction of oyster reefs fails. Summary of the invention

[0005] In order to overcome the deficiency of the prior art oyster reef ecological restoration structure in that it has a weak ability to adapt to different tide levels, the present invention provides a tidal fluctuation-adaptive wave-breaking oyster reef structure, which can adapt to tidal changes and has a stable oyster reef generation efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions.

[0007] A tidal fluctuation-adaptive wave-breaking oyster reef structure comprises a wave-breaking base and an upper reef body, the wave-breaking base and the upper reef body are floatingly connected, the height of the wave-breaking base is lower than the historical lowest water level line, the wave-facing surface of the wave-breaking base is inclined, the upper reef body comprises a floating reef body, and the floating reef body is provided with an oyster attachment structure.

[0008] The wave-breaking base of the present application realizes seabed wave breaking through an inclined wave-facing surface, and an oyster attachment structure is arranged on the upper reef body to realize oyster growth and realize the formation of oyster reefs. Since the upper reef body and the wave-breaking base are floatingly arranged, when the tide level changes, the upper reef body floats therewith, thereby being able to adapt to the tide level changes, and the generation efficiency of the oyster reef is stable.

[0009] Preferably, the floating reef body comprises a main body and a buoy with a hollow interior, the main body covers the outer wall of the buoy and is fixedly arranged, and the oyster attachment structure is arranged at the boundary of the main body and / or outside the main body. The buoy provides buoyancy to realize the floating setting of the floating reef body in the seawater, and the main body can be made of concrete or other materials to cover the buoy to realize the preliminary shaping of the reef body.

[0010] Preferably, the upper reef also includes a connection assembly connecting adjacent floating reefs, the connection assembly is rotatably connected to a connection ring, and the connection ring is connected to the wave-breaking base through a chain. The rotation arrangement of the connection ring and the connection assembly allows the upper reef to rotate when the tide level changes and the buoyancy changes, so that all sides of the upper reef can be used for oysters to climb and survive. The chain connection method makes the height of the upper reef not fixed, and the upper reef can better cooperate with the tide level changes and buoyancy to rise and fall.

[0011] Preferably, the connection assembly includes a connection shaft and connection chains at both ends of the connection shaft, and the connection chain is connected to the buoy. The connection assembly connected to adjacent floating reef bodies includes a connection chain, and the distance between adjacent floating reef bodies can fluctuate with waves, reducing the stress of buoyancy on the connection assembly.

The oyster attachment structure enables oysters to survive on the body, and the number of oysters on the wave-facing side of the body is greater than that on other sides. In the process of continuous attachment of oysters, the wave-facing side of the body rotates to face downward. When there are too many oysters or they grow larger, the clamping position of the oyster attachment structure on this side falls off. The oyster attachment structure is connected to the body at only one end, and the gravity of the oyster attachment structure drives the body to rotate, so that different sides of the body are arranged to face the waves, so that more oysters can be attached to most sides of the body, the utilization rate of the floating reef body is high, and the efficiency of oyster reef formation is stable.

[0013] Preferably, the wave-breaking base comprises a first base block and a second base block which are arranged in sequence along the tide direction, and the maximum height of the second base block is higher than that of the first base block, so as to have a multi-layer wave-breaking effect.

[0014] Preferably, the first base blocks are arranged at intervals, and the second base block is arranged between two adjacent first base blocks and simultaneously connects the two first base blocks. When the bottom wave rises with the tide, it first contacts the first base block, is diverted by the first base block and the interval between the adjacent first base blocks, and then cooperates with the second base block, so that the wave-breaking effect is reliable.

[0015] Preferably, the cross-section of the first base block is an arc, the cross-section of the second base block is an arc, one end of the second base block is fixedly connected to the upper side of the first base block, and the other end of the second base block is provided with a fixing block. The lower part of the first base block and the second base block can be used as a breeding space for oysters, and the fixing block increases the stability of the second base block.

[0016] Preferably, a plug-in strip is provided at one end of the second base block, and a plug-in slot is provided on the first base block, and the plug-in strip and the plug-in slot are plugged in.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0022] In the description of the present invention, it is necessary to understand that the technical features defined by the terms "first", "second" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present invention.

[0023] Example 1 like Figures 1 to 5 As shown, a tidal fluctuation-adaptive wave-breaking oyster reef structure comprises a wave-breaking base 1 and an upper reef body, the wave-breaking base 1 and the upper reef body are floatingly connected, the height of the wave-breaking base 1 is lower than the historical lowest water level line, the wave-facing surface of the wave-breaking base 1 is inclined, the upper reef body comprises a floating reef body 2, and the floating reef body 2 is provided with an oyster attachment structure 23.

[0024] The wave-breaking base 1 of the present application realizes seabed wave breaking through an inclined wave-facing surface, and an oyster attachment structure 23 is arranged on the upper reef body to realize oyster growth and realize the formation of oyster reefs. Since the upper reef body and the wave-breaking base 1 are floatingly arranged, when the tide level changes, the upper reef body floats therewith, thereby being able to adapt to the tide level changes, and the generation efficiency of the oyster reef is stable.

[0025] The wave-breaking base 1 includes a first base block 11 and a second base block 12 which are arranged in sequence along the direction of rising tide, 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. It has a multi-layer wave-breaking effect. There are multiple first base blocks 11, and there are multiple second base blocks 12. 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 connects the two first base blocks 11 at the same time. When the bottom wave rises with the tide, it first contacts the first base block 11, and after being diverted by the first base block 11 and the interval between the adjacent first base blocks 11, it cooperates with the second base block 12, and the wave-breaking effect is reliable.

[0026] In this embodiment, the cross-sectional shape of the first base block 11 is an arc, and the cross-sectional shape of the second base block 12 is an arc. 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-facing side of the first base block 11 and the second base block 12 are both arc surfaces to form an inclined wave-breaking 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 in. The first base block 11 and the second base block 12 are matched through the plug-in strip 13 and the plug-in groove 14, and have high integrity, and the overall structure of the wave-breaking base 1 is highly reliable. A fixed block 10 is provided at the end of the second base block 12 away from the first base block 11. The fixed block 10 increases the stability of the second base block 12. The first base block 11 and the second base block 12 not only serve as wave-breaking structures, but also serve as the overall lower counterweight of the oyster reef, and are made of high-density materials such as bricks, stones, metals, etc.

[0027] The upper reef body is the forming part of the reef body, and the upper reef body floats or suspends in the water body on the upper side of the wave-breaking base 1. The upper reef body includes a number of floating reef bodies 2 and a connecting assembly connecting adjacent floating reef bodies 2. The floating reef body 2 includes a main body 21 and a buoy 22 with a hollow interior. The buoy 22 is closed at both ends, and the interior of the buoy 22 is hollow. The density is less than that of the water body, and it has a large buoyancy. The main body 21 covers the outer wall of the buoy 22 and is fixed. In order to extend the service life of the buoy 22, the buoy 22 is made of plastic material. The main body 21 is cast and formed on the outside of the buoy 22 with concrete, and the buoy 22 has ribs extending radially outward to improve the bonding between the main body 21 and the buoy 22. The oyster attachment structure 23 is arranged on the outside of the main body 21.

[0028] The connecting assembly is rotatably connected with a connecting ring 24, and the connecting ring 24 is connected to the wave-breaking base 1 through a chain 25. The chain 25 is connected to the upper side of the fixed block 10. The rotation arrangement of the connecting ring 24 and the connecting assembly allows the upper reef to rotate when the tide level changes and the buoyancy changes, so that all sides of the upper reef can be used for oysters to climb and survive. The way the chain 25 is connected makes the height of the upper reef not fixed, and the upper reef can better cooperate with the tide level change and the buoyancy effect to rise and fall.

[0029] The connection assembly includes a connection shaft 26 and connection chains 27 at both ends of the connection shaft 26, and the connection chain 27 is connected to the buoy 22. The connection assembly connected to adjacent floating reef bodies 2 includes a connection chain 27, and the distance between adjacent floating reef bodies 2 can fluctuate with waves, and can also rotate relatively, reducing the stress of buoyancy on the connection assembly.

[0030] In this embodiment, the outer contour of the cross-section of the main body 21 is a rounded equilateral triangle, and the oyster attachment structure 23 is an alloy cage or a mesh bag. One end of the oyster attachment structure 23 is hung or rotatably connected to the arc surface corresponding to the rounded corner of the main body 21, and the other end of the oyster attachment structure 23 is detachably clamped to the arc surface corresponding to the rounded corner of the main body 21. The clamping can be achieved by clamping the clamping teeth and the clamping blocks into the clamping grooves on the surface of the main body 21. There are independent mesh bags corresponding to the three side surfaces of the main body 21. The oyster attachment structure 23 enables oysters to survive by attaching to the main body 21. The number of oysters on the wave-facing side of the main body 21 is more than that on other sides. In the process of continuous oyster climbing, the initial wave-facing side 28 of the main body rotates to face downward, that is, Figure 1 When there are too many oysters or they grow larger, the oyster attachment structure 29 on the initial wave-facing surface is disconnected from the clamping position so that only one end is connected to the body 21. The gravity of the oyster attachment structure drives the body 21 to rotate, forming a Figure 5 In the state shown, the remaining two surfaces face the waves, the wave-facing surface 30 located at the bottom is inclined downward and has a large wave-facing area, and the wave-facing surface 31 located at the top is inclined upward and has a small inclination angle. As the number of oysters on the wave-facing surface located at the bottom increases, the main body further rotates to increase the wave-facing area of ​​the wave-facing surface located at the bottom. When the number of oysters on the wave-facing surface located at the bottom further increases, the oyster attachment structure 32 on the wave-facing surface located at the bottom also falls off, further driving the main body to rotate. At this time, the wave-facing area on the wave-facing surface located at the top reaches the maximum, so that different sides of the main body 21 have the opportunity to face the waves, so that most sides of the main body 21 can cling to more oysters, the utilization rate of the floating reef body 2 is high, the oyster reef forming efficiency is stable, and there will be no situation where only one side of the floating reef body 2 clings to oysters, causing the connection parts of adjacent floating reef bodies 2 to be damaged by large stress.

[0031] As a simple replacement for the above solution, the outer contour of the cross section of the body 21 may be a rounded square, a pentagon, or the like.
