Description

Technical Field

[0001] The invention relates to the technical field of artificial oyster reefs, in particular to a grid-type air-permeable oyster reef device. Background Art

[0002] Oyster reefs are three-dimensional structures formed by the accumulation of living oysters, dead oyster shells, and other reef organisms. Located in intertidal and subtidal zones, they purify water, remove nitrogen, stabilize coastlines, and provide habitats for over 200 species. Oyster reefs are closely linked to fish reproduction, serving not only as a breeding ground for fish but also as a key habitat for sustaining nearshore fish populations. The core of this relationship lies in the fact that oyster reefs, through their unique physical structure and ecological functions, support the entire fish reproduction cycle, from spawning to juvenile development.

[0003] Existing natural oyster reefs have experienced overfishing and habitat degradation and are the target of ecological restoration around the world. Therefore, building a habitat suitable for the growth of oyster larvae is the key to the restoration of oyster resources. In the prior art, a Chinese invention with publication number CN114304027B discloses a grid-type permeable oyster reef device, which specifically relates to the technical field of artificial oyster reefs, including an oyster reef body, the shape of which is trapezoidal and the area of ​​the trapezoidal cross-section at the top is smaller than that at the bottom, and two triangular wing plates are provided on each of the four sides of the oyster reef body, the two triangular wing plates being the same as the bottom. The angular wing plates are arranged vertically on the sides of the oyster reef body, and the multiple triangular wing plates on two adjacent sides are staggered on the vertical plane. The outer periphery of the oyster reef body is covered with a layer of basalt grid. The present invention combines basalt composite fiber and basalt grid with the trapezoidal oyster reef body, which not only improves the overall strength but also reduces the overall weight, thereby reducing the settlement depth of the entire device and achieving the purpose of anti-settling. In addition, oyster seedlings can be directly cultured on the basalt grid and then fixed to the reef body, which can also improve the utilization rate and surface attachment rate of oyster seedlings. In the above technology, by combining basalt composite fiber and basalt grid with the trapezoidal oyster reef body, it can not only improve the overall strength but also reduce the overall weight, so as to reduce the settlement depth of the entire device and achieve the purpose of anti-sedimentation. However, during long-term use, it is easy to shift due to the erosion of ocean currents, affecting its stability and ecological function. Summary of the Invention

When the oyster reef is placed on the seabed, the oyster reef presses down the supporting column due to its own gravity, and the supporting column moves upward relative to the fixed rod. When the supporting column moves upward, it supports the anchor rod outward through the cooperation of the bevel groove and the bevel block. The anchor rod moves downward and is inserted into the seabed, frictionally engaging with the seabed to enhance the pull-out resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] like Figures 1-10 As shown, the present application provides a grid-type permeable oyster reef device, comprising an oyster reef body 1, wherein a wing plate 2 is provided on the side of the oyster reef body 1; The oyster reef body 1 is in the shape of a trapezoid, and the area of ​​the trapezoidal cross section at the top is smaller than that at the bottom; The wing plates 2 are arranged on four groups of side surfaces of the oyster reef body 1; In this embodiment, the oyster reef body 1 is designed to be trapezoidal. It is known that the angle between the inclined surface and the horizontal is the main factor in the formation of upwelling. Therefore, when the water flows through the inclined surface of the trapezoid, an upwelling will be generated. The generated upwelling will transport the bottom sediments and nutrients to the upper water body, thereby accelerating the circulation rate of nutrients.

[0021] Specifically, such as Figure 2-Figure 4 as well as Figure 6 As shown, a grid-type hollow oyster reef device further includes a fixing rod 4, which is arranged at the bottom of the connecting block 3, and a fastening assembly is provided inside the fixing rod 4 for grabbing the seabed; The fastening assembly includes anchor rods 6 slidably arranged on the connecting block 3 , and the anchor rods 6 are provided in multiple groups, and the multiple groups of anchor rods 6 are distributed in a circumferential manner.

[0022] A countersunk hole 7 is formed at the lower end of the fixing rod 4, a supporting column 5 is inserted into the interior of the countersunk hole 7, and a first return spring 8 is provided between the upper end of the supporting column 5 and the inner top end of the countersunk hole 7; The outer surface of the supporting column 5 is provided with a plurality of first bevel grooves 9 spaced apart at positions corresponding to the ends of the anchor rods 6.

In this embodiment, when the oyster reef 1 is placed on the seabed, the oyster reef 1 presses down the supporting column 5 due to its own gravity, and the supporting column 5 moves upward relative to the fixing rod 4. When the supporting column 5 moves upward, the first bevel groove 9 and the bevel block 10 cooperate to support the anchor rod 6 outward. The anchor rod 6 moves downward and is inserted into the seabed, frictionally engaging with the seabed to enhance the pull-out resistance.

[0023] Specifically, such as Figure 4 As shown, four groups of symmetrically distributed guide blocks 11 are provided at the bottom of the oyster reef body 1, and a guide groove 12 is provided at the upper end of the connecting block 3 corresponding to the position of the guide block 11; The guide block 11 is slidably disposed inside the guide groove 12, and a second limiting block 19 is provided on the side wall of the guide block 11. A second limiting groove 20 is formed on the inner wall of the guide groove 12 at a position corresponding to the second limiting block 19, and the second limiting block 19 is slidably disposed inside the second limiting groove 20. In this embodiment, the guide block 11 and the guide groove 12 cooperate to guide the displacement direction of the oyster reef body 1 when it is impacted by the tide.

[0024] Specifically, such as Figure 3-Figure 5 as well as Figure 7-Figure 9 As shown, a grille-type permeable oyster reef device further includes a connecting block 3, which is slidably arranged at the bottom of the oyster reef body 1, and a shock-absorbing component is provided between the connecting block 3 and the oyster reef body 1 to reduce the impact of the tide on the oyster reef body 1; The shock absorbing assembly includes a first air storage bag 13 provided between the side wall of the guide block 11 and the inner wall of the guide groove 12; A first receiving groove 22 is formed on the side wall of the guide block 11 at a position corresponding to the first air storage bag 13. A second extrusion rod 21 is inserted into the first receiving groove 22, and a third return spring 23 is provided between the end of the second extrusion rod 21 and the inner wall of the first receiving groove 22. The second extrusion rod 21 is elastically arranged in the first receiving groove 22 by the third return spring 23. A through slot 25 is formed on the side wall of the guide block 11 corresponding to the inner wall of the guide groove 12 . The through slot 25 passes through the guide block 11 and communicates with the first receiving groove 22 . A damping rod 26 is inserted into the through slot 25. The damping rod 26 has a triangular structure at one end facing the second extrusion rod 21. A second beveled groove 24 is provided on the side wall of the second extrusion rod 21 at a position corresponding to the end of the damping rod 26. The end of the damping rod 26 passes through the through slot 25 and is inserted into the second beveled groove 24. A third limiting groove 27 is formed on the side wall of the through groove 25, and a third limiting block 28 is provided on the side wall of the damping rod 26 at a position corresponding to the third limiting groove 27. The third limiting block 28 is slidably disposed inside the third limiting groove 27. A fourth return spring 29 is provided between the side wall of the third limiting block 28 and the inner wall of the third limiting groove 27; In this embodiment: when the tide hits the oyster reef body 1, the oyster reef body 1 drives the guide block 11 to move inside the guide groove 12. During the movement, the first air storage bag 13 is compressed. At this time, the second extrusion rod 21 is pushed by the compressed gas, and the second extrusion rod 21 moves along the first receiving groove 22. When moving, through the cooperation of the second bevel groove 24, the damping rod 26 is outwardly supported. The damping rod 26 extends and contacts the side wall of the guide groove 12. The greater the displacement of the oyster reef body 1, the greater the compression of the first air storage bag 13, the greater the support force of the damping rod 26 on the guide groove 12, and the greater the friction overcome by the displacement, which can offset a large amount of the impact force of the tide on the oyster reef body 1.

[0025] Specifically, such as Figure 10 As shown, a grid-type permeable oyster reef device further includes a diversion component, which is arranged on one side of the connecting block 3 and is used to divert the tide; The diversion assembly includes two sets of symmetrically distributed second receiving grooves 30 provided at positions of the connecting block 3 corresponding to the first air storage bag 13. A guide plate 31 is slidably provided inside each of the second receiving grooves 30. The side wall of the guide plate 31 away from the connecting block 3 is arranged in an inclined state. A second air storage bag 32 is provided between the side wall of the deflector 31 and the inner wall of the second receiving groove 30 , and an exhaust pipe 33 is provided between the second air storage bag 32 and the first air storage bag 13 ; In this embodiment, when the first air storage bag 13 is compressed, the gas inside the first air storage bag 13 is discharged to the inside of the second air storage bag 32 through the exhaust pipe 33. The second air storage bag 32 expands and pushes out the guide plate 31. When the tide hits the connecting block 3, the guide plate 31 cooperates to guide the tide, thereby reducing the impact force of the tide on the connecting block 3.

[0026] The present solution is as follows: the oyster reef 1 is placed at a designated location on the seabed. Due to its own gravity, the oyster reef 1 presses down on the supporting column 5, and the supporting column 5 moves upward relative to the fixed rod 4. When the supporting column 5 moves upward, the first bevel groove 9 and the bevel block 10 cooperate to support the anchor rod 6 outward. The anchor rod 6 moves downward and is inserted into the seabed, frictionally engaging with the seabed to enhance the pullout resistance. When the tide hits the oyster reef 1, the oyster reef 1 drives the guide block 11 to move inside the guide groove 12. During the movement, the first air storage bag 13 is compressed. At this time, the second extrusion rod 21 is pushed by the compressed gas and moves along the first receiving groove 22. During the movement, the second extrusion rod 21 cooperates with the second bevel groove 24 to outwardly press against the damping rod 26. The damping rod 26 extends and contacts the side wall of the guide groove 12. The greater the displacement of the oyster reef 1, the greater the compression of the first air storage bag 13, the greater the pressure of the damping rod 26 on the guide groove 12, and the greater the friction overcome by the displacement, which can offset a large amount of the impact force of the tide on the oyster reef 1. When the first air storage airbag 13 is compressed, the gas inside the first air storage airbag 13 is discharged into the second air storage airbag 32 through the exhaust pipe 33. The second air storage airbag 32 expands and pushes out the guide plate 31. When the tide hits the connecting block 3, the guide plate 31 cooperates to guide the tide, thereby reducing the impact force of the tide on the connecting block 3.
