Description

Technical Field

[0001] The invention belongs to the technical field of marine ecological restoration, and in particular relates to a recyclable wave-breaking component for underwater planting of seaweed. Background Art

[0002] Seagrass degradation is a recognized global problem, and my country's seagrass is also facing a severe degradation situation. In recent years, reclamation, destructive dredging, aquaculture and domestic sewage discharge have directly affected the survival of seagrass. Today, my country's seagrass beds are mainly distributed in the South China Sea and the Yellow Sea and Bohai Sea. Among them, the Leting-Caofeidian seagrass bed in the Yellow Sea and Bohai Sea distribution area is the most representative.

[0003] Replanting and restoring seagrass in degraded areas is a project that requires long-term persistence. At present, seagrass planting is mainly carried out by underwater sowing and seedling transplanting. Among them, for the underwater sowing method, since seagrass seeds are planted on the seabed, they are easily impacted by water waves, which affects the rooting of the seeds. Seagrass seeds are stranded on the seabed surface for a long time and are easily destroyed by seabed aquatic organisms. Due to the long rooting period, after the seeds germinate, they will drift with the waves due to the lighter specific gravity, thus affecting the survival rate of seagrass planting. There are also measures to use hydrolyzed materials to make protective boxes to protect seagrass seeds from water wave impacts, but the hydrolysis process of hydrolyzed materials is relatively long, and the hydrolyzed materials will also have a negative impact on the seawater quality. Therefore, from an environmental protection perspective, this method should not be promoted. Summary of the invention

[0009] For example, the inner wall of the wave-breaking sleeve is provided with a limiting rib, the peripheral wall of the inner sleeve is provided with a limiting groove, the limiting groove extends upward from the lower end of the inner sleeve and is suitable for the limiting rib to extend into, and the lower end of the inner sleeve is provided with an inwardly bent pressing edge; wherein, when the inner sleeve slides until the limiting rib abuts against the top of the limiting groove, the dry mud cake is separated from the wave-breaking sleeve under the pressing action of the pressing edge.

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "upper", "lower", "front", "rear", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0020] Please also read Figures 1 to 4 The recyclable wave-breaking component for underwater planting of seaweed provided by the present invention is now described. The recyclable wave-breaking component for underwater planting of seaweed comprises a wave-breaking sleeve 10, a dry mud cake 20, a wet mud layer 30, and a mesh cover 40; the wave-breaking sleeve 10 is used to be plugged and fixed on the underwater ground of the seaweed planting area; the dry mud cake 20 is embedded in the bottom of the wave-breaking sleeve 10, and is used to be loosened from the wave-breaking sleeve 10 when immersed in seawater; the wet mud layer 30 is laid on the upper surface of the dry mud cake 20, and the wet mud layer 30 is used to fix seaweed seeds; the mesh cover 40 is arranged at the top of the wave-breaking sleeve 10, and has an avoidance hole in the center, and the avoidance hole is used to avoid the growing seaweed stems and leaves.

[0021] It should be noted that, in the present embodiment, the wave-breaking sleeve 10 may be circular, triangular, square or other polygonal shapes. Since the underwater ground in the seaweed planting area is sand, gravel and soil, when the wave-breaking sleeve 10 is placed on the underwater ground, its lower end is inserted into the underwater ground and fixed. On this basis, the position where the dry mud cake 20 is embedded in the wave-breaking sleeve 10 is close to the lower end of the wave-breaking sleeve 10. When the lower end of the wave-breaking sleeve 10 is inserted into the underwater ground, the dry mud cake 20 is pressed against the underwater ground.

[0022] In this embodiment, the wave-breaking sleeve 10 can be made of monel alloy or stainless steel. Considering the fluidity of underwater surface seawater, 304 stainless steel or 316 stainless steel can be preferably used to make the wave-breaking sleeve 10, so as to ensure the chemical stability of the wave-breaking sleeve 10. First, it can avoid corrosion damage to the wave-breaking sleeve 10, and second, it can avoid corrosion of the wave-breaking sleeve 10 under the corrosion of seawater and affect the water quality. Similarly, the mesh cover 40 is also preferably made of 304 stainless steel or 316 stainless steel.

[0023] In this embodiment, the mesh cover 20 and the wave-breaking sleeve 10 can be an integrated structure, that is, the mesh cover 20 is fixedly covered on the top of the wave-breaking sleeve 10, thereby preventing the mesh cover 20 from falling off under the impact of seabed waves. The mesh cover 20 and the wave-breaking sleeve 10 can also be a movable connection structure. For example, the mesh cover 20 forms a plug-in fit with the wave-breaking sleeve 10 based on a plug-in body.

[0024] It should be explained that the avoidance hole arranged in the center of the mesh cover 40 in the present embodiment enables the stems and leaves of the seaweed seedlings to grow freely upward and extend out of the wave-breaking sleeve 10; specifically, the position where the seaweed seeds are fixed on the wet mud layer 30 corresponds to the position of the avoidance hole, and the function of the mesh cover 40 is to provide a water-permeable shield for most of the top area of ​​the wave-breaking sleeve 10, on the one hand to prevent the seaweed seeds from being unstable in the wet mud layer 30 (especially when the specific gravity of the seaweed seeds is reduced when they germinate) and floating out of the wave-breaking sleeve 10, on the other hand to ensure that seawater and sand can smoothly enter the internal space of the wave-breaking sleeve 10, thereby meeting the environmental requirements for the growth and development of seaweed. Under normal circumstances, the wave-breaking sleeve 10 can be removed after the seaweed seeds have become seedlings for one month.

[0025] It should be noted that the recyclable wave-breaking component for underwater seaweed planting provided in this embodiment is a prefabricated component, wherein the wave-breaking sleeve 10 and the mesh cover 40 are recyclable and reusable components, and the dry mud cake 20 and the wet mud layer 30 gradually merge into one with the underwater ground under immersion in seawater. Specifically, seabed mud is made into a cake shape through a mold, dried and formed into a dry mud cake 20 and embedded in the bottom of the wave-breaking sleeve 10, or seabed mud is directly filled in the wave-breaking sleeve 10 and then dried to form a dry mud cake 20 at the bottom of the wave-breaking sleeve 10, and then a layer of seabed mud is covered on the dry mud cake 20 to form a wet mud layer 30, and seaweed seeds are pressed into the wet mud layer 30 so that the wet mud layer 30 wraps the seaweed seeds to ensure the fixation stability of the seaweed seeds. It is best to cover the mesh cover 40 to form a planting unit (for ease of description, the structure after embedding the dry mud cake 20 in the wave-breaking sleeve 10 and fixing the seaweed seeds on the wet mud layer 30 and then covering the mesh cover 40 is collectively referred to as a planting unit). When performing seaweed planting operations, multiple planting units can be stacked, and then the stacked multiple planting units are placed layer by layer at the corresponding planting locations, which is beneficial to improving the planting efficiency. Of course, each planting unit can also be taken individually and placed at the planting location.

[0026] The seaweed seeds fixed on the wet mud layer 30 complete the process of germination, rooting and emergence in the seawater within about one month. During this period, the dry mud cake 20 is fully soaked and softened by the seawater, so that the dry mud cake 20 and the inner wall of the wave-breaking sleeve 10 become loose, thereby ensuring that the wave-breaking sleeve 10 can be lifted upward smoothly and avoiding the loosening of the soil at the roots of the seaweed during the lifting process of the wave-breaking sleeve 10, thereby avoiding the seaweed seedlings being washed away by the seabed waves due to the loose roots after the wave-breaking sleeve 10 is removed.

[0027] Compared with the prior art, the recyclable wave-breaking structure for underwater planting of seaweed provided in the present embodiment can serve as a foundation for laying a wet mud layer 30 by embedding a dry mud cake 20 at the bottom of a wave-breaking sleeve 10, fix the seaweed seeds on the wet mud layer 30 and cover the top of the wave-breaking sleeve 10 with a mesh cover 40, and then place the wave-breaking sleeve 10 on the underwater ground in the seaweed planting area. On the one hand, the wave-breaking sleeve 10 can be used to protect the wet mud layer 30, thereby preventing the wet mud layer 30 from being excessively scoured by seabed waves, which is conducive to the smooth rooting of the seaweed seeds, and at the same time, the mesh cover 40 can be used to protect the wet mud layer 30. 0 protects the seaweed seeds which become lighter in specific gravity after germination, and prevents the seaweed seeds from floating out of the wave-breaking sleeve 10, thereby forming a secondary protection and promoting the smooth rooting of the seaweed, thereby improving the survival rate of the seaweed; on the other hand, the dry mud cake 20 gradually becomes soft and loosened from the wave-breaking sleeve 10 under the immersion of seawater as the seaweed takes root and grows stems and leaves. At this time, the wave-breaking sleeve 10 and the net cover 40 can be lifted up together and recycled for reuse, which can not only reduce the consumables for seaweed planting and save costs, but also prevent the wave-breaking sleeve 10 and the net cover 40 from being immersed in seawater for a long time to affect the water quality, thereby improving environmental protection.

[0028] In some embodiments, see Figure 2 and Figure 3 The lower end of the wave-breaking sleeve 10 is provided with teeth 11 for inserting into the underwater ground at intervals along its circumference, the peripheral wall of the wave-breaking sleeve 10 is provided with a through hole array 12, the dry mud cake 20 is located above the teeth 11 and the dry mud cake 20 is provided with a water-permeable hole array 21.

[0029] The lower end of the wave-breaking sleeve 10 forms a zigzag structure based on a circle of teeth 11. The teeth 11 are inserted into the underwater ground to ensure the stability of the placement of the wave-breaking sleeve 10 on the underwater ground, and prevent the wave-breaking sleeve 10 from being moved by the scouring of seabed waves. At the same time, a through-hole array 12 is arranged on the peripheral wall of the wave-breaking sleeve 10 to allow seawater and fine sand to pass through the through-holes into the interior of the wave-breaking sleeve 10. On the one hand, it can reduce the impact force of seawater on the wave-breaking sleeve 10, and on the other hand, it can deposit and cover fine sand on the wet mud layer 30, thereby preventing the wet mud layer 30 from being scour by seawater and causing seaweed seeds to be exposed, thereby preventing underwater organisms from biting and eating seaweed seeds, and improving the survival rate of seaweed; the water-permeable hole array 21 is arranged on the dry mud cake 20, which is conducive to seawater passing through the water-permeable holes. On the one hand, it contacts the wet mud layer 30, thereby ensuring the development environment of the seaweed seeds. On the other hand, it is conducive to the infiltration and softening of the dry mud cake 20 by seawater, so as to facilitate the separation of the dry mud cake 20 from the wave-breaking sleeve 10 in the later stage, and avoid the wave-breaking sleeve 10 being lifted up and bringing up the soil at the roots of the seaweed when the wave-breaking sleeve 10 is removed after the seaweed seedlings, thereby improving the rooting stability of the seaweed after the wave-breaking sleeve 10 is removed, and then improving the survival rate of the seaweed; because the dry mud cake 20 is embedded in the upper position of the tooth 11, when the tooth 11 is inserted into the underwater ground, the dry mud cake 20 can be pressed against the underwater ground, and the dry mud cake 20 can be combined with the underwater ground after being soaked and softened by seawater, thereby ensuring the stability of the seaweed taking root and growing at the current position after the wave-breaking sleeve 10 is removed in the later stage.

[0030] Some possible implementations include Figure 2 and Figure 3 As shown, the inner wall of the wave-breaking sleeve 10 is provided with a plurality of annular grooves 13 spaced apart above the inserting teeth 11, and each annular groove 13 is filled with mud, which is bonded to the peripheral wall of the dry mud cake 20. The annular grooves 13 combined with the mud can improve the reliability of the dry mud cake 20 in the wave-breaking sleeve 10, thereby avoiding the phenomenon of the dry mud cake 20 falling off during the transportation and transfer and placement of the wave-breaking sleeve 10 in the seaweed planting area, thereby ensuring the smoothness of the seaweed planting operation process.

[0031] Specifically, in the prefabrication stage, the seabed mud can be directly filled at the bottom of the wave-breaking sleeve 10. During this process, the seabed mud automatically enters each annular groove 13. After the seabed mud is dried and solidified to form a dry mud cake 20, it can be reliably connected to the inner wall of the wave-breaking sleeve 10 based on the protrusions embedded in the annular groove 13, thereby avoiding the problem of the dry mud cake 20 falling off. At the same time, the part of the dry mud cake 20 embedded in the annular groove 13 softens under the immersion of seawater and loses the hooking effect with the annular groove 13. Therefore, it can also ensure that the wave-breaking sleeve 10 can be smoothly lifted up without moving the soil at the root of seaweed.

[0032] Of course, the dry mud cake 20 can also be directly prefabricated using a mold to form a smooth circumferential wall. When embedded in the wave-breaking sleeve 10, the circumferential wall of the dry mud cake 20 is smeared with mud diluted with seabed mud, and the mud is also brushed into each annular groove 13. After the mud is dried and solidified, the dry mud cake 20 and the wave-breaking sleeve 10 can be reliably bonded, thereby preventing the dry mud cake 20 from falling off. The dry mud softens under the immersion of seawater, loosening the dry mud cake 20 and the wave-breaking sleeve 10, thereby facilitating the subsequent removal of the wave-breaking sleeve 10.

[0033] As a specific structure of the mesh cover 40, please refer to Figure 2 and Figure 3 The mesh cover 40 includes an inner sleeve 41 and a mesh ring 42. The inner sleeve 41 is slidably inserted into the wave-breaking sleeve 10 from top to bottom. The mesh ring 42 is connected to the top of the inner sleeve 41, and the inner ring surface of the mesh ring 42 forms a avoidance hole; wherein, the inner sleeve 41 is used to press the dry mud cake 20 when the wave-breaking sleeve 10 is lifted upward; the top of the inner sleeve 41 extends upward from the wave-breaking sleeve 10, and the top of the inner sleeve 41 is suitable for inserting into the lower end of the wave-breaking sleeve 10.

[0034] The net ring 42 is covered on the top of the wave-breaking sleeve 10 by the plug-in cooperation between the inner sleeve 41 and the wave-breaking sleeve 10. On the one hand, it is convenient for assembly and connection. On the other hand, when the wave-breaking sleeve 10 is removed, the lower end of the inner sleeve 41 can be used to press the dry mud cake 20 (in fact, the dry mud cake 20 has been soaked and softened by seawater at this time, but there is still a certain adhesion and friction with the inner wall of the wave-breaking sleeve 10). At the same time, the wave-breaking sleeve 10 is pulled upward, so that the dry mud cake 20 and the wave-breaking sleeve 10 are smoothly separated, thereby avoiding the soil at the roots of the seaweed (formed by the soaking and softening of the dry mud cake 20) being driven in during the process of lifting the wave-breaking sleeve 10, thereby ensuring the stability of the soil around the roots of the seaweed.

[0035] Since the top end of the inner sleeve 41 extends out of the wave-proof sleeve 10, the following method can be used: Figure 4The stacking method shown stacks multiple wave-breaking sleeves 10 together up and down, and utilizes the top end of the lower inner sleeve 41 to be plugged into the bottom end of the upper wave-breaking sleeve 10 to ensure the stacking stability, thereby facilitating the transportation and transfer of the stacked multiple planting units. During planting operations, the stacked multiple planting units can be taken and released layer by layer to each planting point, thereby improving the efficiency of the planting operation.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner wall of the wave-breaking sleeve 10 is provided with a limiting rib 14, and the peripheral wall of the inner sleeve 41 is provided with a limiting groove 411, the limiting groove 411 extends upward from the lower end of the inner sleeve 41 and is suitable for the limiting rib 14 to extend into, and the lower end of the inner sleeve 41 is provided with an inwardly bent pressing edge 412; wherein, when the inner sleeve 41 slides until the limiting rib 14 abuts against the groove top of the limiting groove 411, the dry mud cake 20 is separated from the wave-breaking sleeve 10 under the pressing action of the pressing edge 412.

[0037] In order to prevent the inner sleeve 41 from continuing to slide down and fall off after the wave-breaking sleeve 10 is lifted up until the dry mud cake 20 falls off from the lower end of the wave-breaking sleeve 10, a limiting rib 14 and a limiting groove 411 are arranged to cooperate with each other. When the dry mud cake 20 falls off from the lower end of the wave-breaking sleeve 10, the groove top of the limiting groove 411 can abut against the limiting rib 14, thereby limiting the inner sleeve 41 from continuing to slide down relative to the wave-breaking sleeve 10, and preventing the mesh cover 40 from falling off and being lost when the wave-breaking sleeve 10 is removed; in addition, since the dry mud cake 20 is soaked and softened by seawater immersion, an inwardly bent pressing edge 412 is arranged at the lower end of the inner sleeve 41, and the pressing edge 412 is used to press the dry mud cake 20, thereby increasing the force-bearing area of ​​the dry mud cake 20 and ensuring a smooth falling-off process of the dry mud cake 20 and the wave-breaking sleeve 10.

[0038] It should be noted that the peripheral wall of the inner sleeve 41 is provided with a plurality of limiting grooves 411 at intervals along its circumference, the peripheral wall of the wave-breaking sleeve 10 is provided with a through hole array 12, each row of through holes in the through hole array 12 corresponds to one of the limiting grooves 411, and the inner wall of the wave-breaking sleeve 10 is provided with a plurality of limiting ribs 14 at intervals along its circumference, each limiting rib 14 corresponds to one of the limiting grooves 411 (the number may be equal and one-to-one corresponding, or the number of limiting ribs 14 may be less than the limiting grooves 411). The corresponding cooperation of the plurality of limiting ribs 14 and the limiting grooves 411 can ensure the support stability of the inner sleeve 41, and prevent the inner sleeve 41 from twisting and falling off. At the same time, each limiting groove 411 can avoid blocking the through hole array 12, thereby ensuring that the seawater can pass through the through hole array 12 and flow smoothly between the inside and outside of the wave-breaking sleeve 10, thereby reducing the impact of the seawater on the wave-breaking sleeve 10.

[0039] For some possible implementations, see Figures 5 to 9The recyclable wave-breaking structure for underwater planting of seaweed also includes a lifting aid 50, which is provided with a plurality of lifting heads; the top of the wave-breaking sleeve 10 is provided with a lifting flange 15 folded toward the periphery thereof, and the lifting flange 15 is provided with a plurality of slots 151; wherein each lifting head is used to correspondingly engage with each slot 151. By engaging each lifting head of the lifting aid 50 with each slot 151 on the lifting flange 15 folded at the top of the wave-breaking sleeve 10, the wave-breaking sleeve 10 can be lifted with the aid of the lifting aid 50, so that the operator can perform seaweed planting operations in a standing posture, which is conducive to reducing labor intensity. At the same time, when there is seawater in the seaweed planting area, the lifting aid 50 can be used to connect the wave-breaking sleeve 10 and extend it underwater for planting operations, thereby eliminating the limitation that the seaweed planting operations can only be performed within a limited time when the underwater ground is exposed during low tide.

[0040] Specifically, the optional structure of the lifting aid 50 in this embodiment is as follows: Figure 6 As shown, the lifting aid 50 includes a disk rack 51 and a driving assembly 53; wherein, the disk rack 51 is provided with a plurality of lifting rods 52 at intervals along the circumference of the wave-proof sleeve 10, the lifting rods 52 are rotatably connected to the disk rack 51, and the lower end of each lifting rod 52 is provided with a lifting head, which has a lifting state in which it rotates to engage with the slot 151 and a release state in which it is disengaged from the slot 151; the driving assembly 53 is arranged on the disk rack 51, and the output end of the driving assembly 53 is connected to each lifting rod 52, and is used to drive each lifting rod 52 to rotate synchronously to switch the lifting state and the release state.

[0041] When seaweed is planted, each lifting rod 52 is passed through each slot 151 on the lifting flange 15, and then the driving assembly 53 drives each lifting rod 52 to rotate synchronously, so that the lifting head at the lower end of each lifting rod 52 is engaged with each slot 151. In this case, the length of the lifting rod 52 is the sum of the heights of the plurality of wave-breaking sleeves 10. Figure 5As shown, for multiple wave-breaking sleeves 10 stacked, the lifting head can be engaged with the card slot 151 on the bottom wave-breaking sleeve 10 to lift multiple wave-breaking sleeves 10 at one time and place them at a planting point, and then the driving component 53 drives each lifting rod 52 to rotate and switch to a released state, and then the upper lifting disc frame 51 is used to separate each lifting head from the bottom wave-breaking sleeve 10, and then the driving component 53 drives each lifting rod 52 to rotate and switch to a lifting state again, so that the lifting head and The card slot 151 of the second layer of wave-breaking sleeve 10 from bottom to top is engaged, and then the other wave-breaking sleeves 10 except the bottom layer can be lifted up together, and the wave-breaking sleeve 10 of the bottom layer stays at the current planting point, and then the remaining wave-breaking sleeves 10 are transferred to the next planting point together under the drive of the lifting auxiliary device 50, and the above action is repeated to release another layer of wave-breaking sleeve 10 until all the wave-breaking sleeves 10 are placed, thereby completing the seaweed planting process at multiple planting points. The operation is simple and labor-saving, and the planting efficiency is high.

[0042] When the seaweed takes root and becomes a seedling, the wave-breaking cover 10 is removed. Figure 7 , hold the disc rack 51 and extend the lifting rod 52 into the sea water, drive the lifting rods 52 to rotate through the driving assembly 53 so that each lifting head is correspondingly engaged with the slot 151, and then lift the disc rack 51 upward to drive the wave-breaking sleeve 10 to move upward and separate from the soaked and softened dry mud cake 20. There is no need for the operator to bend down and enter the water to remove the wave-breaking sleeve 10, thereby improving the removal efficiency of the wave-breaking sleeve 10 and reducing labor intensity.

[0043] Optionally, the structure of the driving component 53 in this embodiment is as follows: Figure 6 As shown, the driving assembly 53 includes a plurality of swing arms 531, a driving handle 532, a turntable 533, and a plurality of connecting rods 534; wherein, the plurality of swing arms 531 are respectively connected to each lifting rod 52; the driving handle 532 is rotatably connected to the disk rack 51; the turntable 533 is rotatably connected to the disk rack 51 and is connected to the driving handle 532; a plurality of connecting rods 534 are distributed at intervals along the circumference of the turntable 533, one end of the connecting rod 534 is hinged to the edge of the turntable 533, and the other end is hinged to one of the swing arms 531.

[0044] By rotating the driving handle 532, the turntable 533 is driven to rotate, and the turntable 533 drives each connecting rod 534 to pull each swing arm 531 to swing synchronously, so that the lifting rod 52 connected to the swing arm 531 rotates to switch between the lifting state and the releasing state, which is simple and convenient to operate.

[0045] Specifically, Figure 6As shown, the above-mentioned disk rack 51 includes a top plate 511 and a bottom plate 512 which are spaced apart from each other, and a space for accommodating a turntable 533, a connecting rod 534 and a swing arm 531 is formed between the top plate 511 and the bottom plate 512. Each lifting rod 52 passes through the top plate 511 and the bottom plate 512 and rotates with the two. The turntable 533 is rotatably connected to the bottom plate 512, and the driving handle 532 is rotatably connected to the top plate 511 and is located above the top plate 511. The rotating shaft of the driving handle 532 is fixedly connected to the rotating shaft of the turntable 533 (or the two use the same rotating shaft).

[0046] By rotating the top plate 511 and the bottom plate 512 spaced apart from each other and the lifting rod 52, two constraint points can be formed on the lifting rod 52, thereby improving the connection stability of the lifting rod 52. Utilizing the space between the top plate 511 and the bottom plate 512 to accommodate the driving assembly 53 can prevent the driving assembly 53 from colliding with the human body during movement, thereby improving operational safety.

[0047] In order to facilitate the lifting operation, Figure 7 As shown, two lifting handles 513 are provided on the top plate 511 , and the two lifting handles 513 are symmetrically arranged on both sides of the driving handle 532 .

[0048] For example, see Figure 8 The lower end of the lifting rod 52 is provided with a clamping rib 521 extending along its radial direction, the clamping rib 521 forms a lifting head, and the clamping groove 151 extends along the radial direction of the wave-proof sleeve 10 to the edge of the lifting flange 15; wherein, when the lifting rod 52 is rotated until the extension direction of the clamping rib 521 is consistent with that of the clamping groove 151, a released state is formed.

[0049] The lower end of the lifting rod 52 forms an L-shaped lifting head based on the clamping rib 521, and the clamping groove 151 extends to the edge of the lifting flange 15 to form a U-shaped opening groove. When the lifting rod 52 rotates until the extension direction of the clamping rib 521 is consistent with that of the clamping groove 151, the clamping rib 521 can pass through the clamping groove 151 from bottom to top (when releasing the wave-breaking sleeve 10) or from top to bottom (when grabbing the wave-breaking sleeve 10). After the clamping rib 521 passes through the clamping groove 151 from top to bottom, the lifting rod 52 can be rotated to make the clamping rib 521 swing to the side of the clamping groove 151, so that the clamping rib 521 is hooked on the bottom surface of the lifting flange 15 located on the side of the clamping groove 151. In this way, when the disk rack 51 is lifted upward, each lifting rod 52 drives the wave-breaking sleeve 10 to be lifted together, and the structure is simple and stable.

[0050] For some examples, see Figure 7 The lifting aid 50 also includes a pressure relief ring 54, which is slidably connected to each lifting rod 52, and has an operating rod 541 that is slidably penetrated through the disc frame 51. The top end of the operating rod 541 passes through the disc frame 51 upward and is provided with a pressing handle 542; wherein the pressure relief ring 54 is used to press the mesh cover 40 downward when the wave-proof sleeve 10 is lifted upward.

[0051] It should be noted that the above-mentioned pressure relief ring 54 is used in conjunction with the mesh cover 40 composed of the inner sleeve 41 and the ring net. When the seaweed takes root and seedlings and the wave-breaking sleeve 10 is removed, each lifting rod 52 is engaged with the corresponding slot 151, and then the operator presses the pressing handle 542 downward to make the pressure relief ring 54 press against the edge of the mesh cover 40. At the same time, the operator pulls up the disc frame 51 (the lifting handle 513 is located on the side of the pressing handle 542, and the lifting handle 513 can be lifted upward with four fingers while the thumb presses the pressing handle 542 downward) to make the wave-breaking sleeve 10 move upward relative to the mesh cover 40 and separate from the dry mud cake 20. This can prevent the soil around the roots of the seaweed from being driven upward during the lifting of the wave-breaking sleeve 10, thereby ensuring the firmness of the roots of the seaweed after the wave-breaking sleeve 10 is removed, and improving the survival rate of seaweed planting.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
