Description

Technical Field

[0001] This utility model relates to the field of sea grape cultivation, and in particular to a sea grape sandwich snap-on inoculation rack. Background Technology

[0002] In the production of sea grape aquaculture, the inoculation rack is a component in the aquaculture system that carries seedlings and provides an attachment surface for the algae. Since the inoculation rack needs to meet the requirements of seedling constraint, water exchange and rack expansion in the underwater environment, its structural design is crucial and directly affects the uniformity of sea grape attachment and aquaculture yield.

[0003] In related technologies, a mesh frame structure is used as a cultivation carrier for sea grapes. For example, the mesh is stretched through the frame and the algae seeds are placed between the upper and lower mesh layers. When suspended or laid flat in the water, the mesh holds the algae seeds in place, thus simplifying the operation and fixing the algae seeds underwater.

[0004] However, in the structure where the upper and lower mesh sheets are sandwiched together, the algae can still shift with the water flow within the large mesh cavity, easily accumulating in localized areas. Furthermore, the lack of uniform constraint along the mesh surface between the upper and lower mesh sheets makes it easy for local gaps to widen under the influence of water flow. Simultaneously, the lack of horizontal and vertical splicing structures between the mesh frames makes it difficult to form continuous, large-scale cultivation beds. Under these circumstances, the cultivation efficiency and yield stability of sea grapes are easily affected. For example, algae accumulation can lead to localized rotting and uneven growth, easily resulting in prolonged cultivation cycles and decreased harvest quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a sea grape sandwich snap-on inoculation rack, which mainly solves the technical problems of the sea grape seed easy to drift and accumulate in the mesh cavity and the difficulty in splicing and expanding between multiple racks.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model relates to a sea grape sandwich snap-on inoculation rack, comprising: The upper fixing frame includes an upper space frame and a first frame. The lower support frame includes a lower grid frame and a second frame. The lower support frame and the upper fixed frame are locked together by self-locking buckles to form a sandwich frame structure. The inner sides of the upper fixed frame and the lower support frame are composed of multiple vertically matched unit space blocks. The self-locking buckles are distributed on the edges of the unit space blocks. A rigid fastener is located on one side of the lower support frame, and the other side of the lower support frame is provided with a first groove that matches the rigid fastener. A flexible fastener is located on one vertical side of the lower support frame, and a second groove matching the flexible fastener is provided on the other vertical side of the lower support frame.

[0007] Preferably, both the first frame and the second frame are rectangular frames with a well-shaped structure in the middle. The width of the upper space frame is smaller than that of the first frame, and the width of the lower space frame is smaller than that of the second frame. The unit space block is formed by corresponding combinations of the vertically matched first frame and the second frame.

[0008] Preferably, the second frame is taller than the first frame, and the first frame is used to overlap the top of the second frame.

[0009] Preferably, the self-locking buckle includes a fastener and a fastening groove, wherein the fastener is located at the edge of the first frame and extends toward the second frame, and the fastening groove is located at the bottom of the second frame, and the fastening groove is correspondingly provided with the fastener.

[0010] Preferably, the rigid fastener includes a wide body and a narrow body, the width of the first groove matches the width of the narrow body, and the edge of the first frame is provided with an insertion interface perpendicular to the first groove, the width of the insertion interface matching the width of the wide body.

[0011] Preferably, the flexible fastener includes an axial portion, a protrusion, and a groove extending from the middle of the protrusion to the inner side of the axial portion. The protrusion is located at one end of the axial portion, the diameter of the axial portion is less than or equal to that of the second groove, and the diameter of the protrusion is greater than that of the axial portion.

[0012] Preferably, the protrusion is frustum-shaped, with the outer diameter of the protrusion closer to the axial portion being larger than that of the second groove, and the outer diameter of the protrusion farther from the axial portion being smaller than that of the second groove.

[0013] Preferably, both the upper and lower space frames are triangular frame structures, and the ends of the triangular frames are provided with support nodes, which are also distributed on the middle sides of the first frame and the second frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention forms multiple unit space blocks enclosed by well-shaped ribs on the inner side of the upper fixing frame and the lower support frame, and distributes self-locking buckles on the edges of each unit space block. This can separate and constrain the algae seeds within each independent unit, and maintain consistent mesh gaps through uniform buckling around the perimeter. This reduces the probability of algae seeds drifting and accumulating in localized areas within the large mesh cavity, thereby improving the uniformity of algae seed attachment in different areas of the inoculation rack and reducing the probability of localized rot and uneven growth caused by algae seed accumulation, thus ensuring the stability of sea grape cultivation yield.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] like Figure 1-6As shown, in an optional embodiment of this application, a sea grape sandwich snap-on inoculation rack is provided, comprising: an upper fixing frame 100, the upper fixing frame 100 including an upper mesh frame 110 and a first frame 120; and a lower support frame 200, the lower support frame 200 including a lower mesh frame 210 and a second frame 220, wherein the lower support frame 200 and the upper fixing frame 100 are locked together by self-locking snaps 300 to form a sandwich frame structure, wherein the inner sides of the upper fixing frame 100 and the lower support frame 200 are composed of multiple vertically matched single... The unit space blocks 400 are assembled together, and the self-locking buckles 300 are distributed on the edge of the unit space blocks 400; rigid buckle 500 is located on one side of the lower support frame 200 in the horizontal direction, and the other side of the lower support frame 200 is provided with a first groove 510 matching the rigid buckle 500; flexible buckle 600 is located on one side of the lower support frame 200 in the vertical direction, and the other side of the lower support frame 200 in the vertical direction is provided with a second groove 610 matching the flexible buckle 600.

[0019] After the upper fixing frame 100 and the lower support frame 200 are fastened together, a sandwich space is formed between the upper mesh frame 110 and the lower mesh frame 210, in which the sea grape algae species are held. Unlike the existing large-area single-cavity clamping method of the upper and lower mesh sheets, the unit space block 400 in this embodiment is formed by the corresponding vertical enclosure of the ribs of the first frame 120 and the second frame 220, dividing the large-area sandwich into multiple independent compartments. The algae species are confined within their respective unit space blocks 400, preventing them from drifting freely with the water flow over a large area or accumulating in a certain area. Each of the self-locking buckles 300 is distributed on the periphery of the unit space block 400, so that the perimeter of each unit area is subject to independent fastening constraints. This ensures the consistency of the sandwich gap in each unit area and avoids the upper and lower mesh surfaces from separating due to insufficient local fastening, allowing the algae species to escape to adjacent units.

[0020] Specifically, in the initial inoculation stage, the sea grape larvae are detached fragments without rhizoids, making them prone to displacement under water flow. Through the separation and constraint of the unit space blocks 400 and the peripheral engagement of the self-locking buckles 300, the larvae are locked within their respective units, preventing them from laterally crossing unit boundaries, thus achieving a uniform distribution of inoculation density. In the later stages of cultivation, the attached and established larvae grow independently within each unit, preventing the stolons of larvae in adjacent units from tangling and knotting, facilitating harvesting unit by unit laterally. The rigid buckle 500 and the flexible buckle 600 are respectively located on the horizontal and vertical sides of the lower support frame 200, used to connect with the corresponding troughs of adjacent inoculation racks, thereby connecting multiple inoculation racks in series to expand into a continuous cultivation bed in both the horizontal and vertical directions.

[0021] In an optional embodiment of this application, the first frame 120 and the second frame 220 are both rectangular frames with a well-shaped structure in the middle. The width of the upper grid 110 is smaller than that of the first frame 120, and the width of the lower grid 210 is smaller than that of the second frame 220. The unit space block 400 is a corresponding combination of the vertically matched first frame 120 and the second frame 220.

[0022] It can be understood that the well-shaped structure refers to a rectangular frame with cross-shaped ribs in the middle, which divide the inner cavity of the frame into multiple sub-regions arranged in a matrix. When the first frame 120 and the second frame 220 are fastened together, their respective well-shaped ribs coincide vertically, and the sub-regions enclosed by the ribs constitute the unit space block 400. The well-shaped ribs serve a dual function: firstly, as separators, they divide the large-area interlayer into multiple unit space blocks 400, restricting the lateral migration of algae between different units; secondly, as the central support skeleton of the mesh surface, the mesh surface width of the upper mesh frame 110 is smaller than that of the first frame 120, and after tensioning, the edge of the mesh surface is located within the frame border. The mesh surface is supported by the frame border and the ribs, and the ribs provide a rigid back support in the middle of the mesh surface, distributing the water flow impact force and algal weight borne by the mesh surface to each node of the frame, reducing the deflection deformation of the mesh surface under load, and keeping the upper mesh frame 110 and the lower mesh frame 210 parallel and attached under stress.

[0023] In an optional embodiment of this application, the second frame 220 is taller than the first frame 120, and the first frame 120 is used to overlap the top of the second frame 220.

[0024] It is understood that the sidewall of the second frame 220 is higher than that of the first frame 120. After the two are fastened together, the joint gap is located in the upper region of the sidewall of the second frame 220. During underwater deployment, the water flow is mainly transverse and tangential. The higher sidewall of the second frame 220 guides the main body of the transverse water flow to the height of the joint gap or above it, maintaining a relatively gentle water flow environment within the interlayer for the algae in the early stage of inoculation, which is conducive to the early implantation of the algae.

[0025] In an optional embodiment of this application, the self-locking buckle 300 includes a fastening member 310 and a fastening groove 320, wherein the fastening member 310 is located at the edge of the first frame 120 and extends toward the second frame 220, the fastening groove 320 is located at the bottom of the second frame 220, and the fastening groove 320 is correspondingly provided with the fastening member 310.

[0026] It can be understood that the fastener 310 extends downward from the edge of the first frame 120. When the upper fixing frame 100 is pressed vertically downward toward the lower support frame 200, the fastener 310 is embedded in the fastening groove 320, and the mating surfaces of the two form a fastening connection. Figure 1-2 As shown, the upper fixing bracket 100 is prevented from detaching upwards, thereby achieving instantaneous locking upon pressure, eliminating the need for the traditional method of binding the mesh frame with cable ties. The self-locking buckles 300 are distributed along the edges of each unit space block 400, ensuring that the four corners or four sides of each unit area are constrained by the locking force. The locking force is evenly transmitted from the perimeter of the frame to the two layers of mesh, preventing the widening of gaps in the central area of ​​the mesh surface due to the lack of internal constraints when a large-area mesh frame is only fixed by the outer perimeter of the frame.

[0027] In an optional embodiment of this application, such as Figure 7 As shown, the rigid fastener 500 includes a wide body portion 520 and a narrow body portion 530. The width of the first groove 510 matches the width of the narrow body portion 530. The edge of the first frame 120 is provided with an insertion interface 540 perpendicular to the first groove 510. The width of the insertion interface 540 matches the width of the wide body portion 520.

[0028] The rigid fastener 500 and the first groove 510 constitute a horizontal splicing structure for adjacent inoculation racks; the rigid fastener 500 has a T-shaped cross-section, the narrow part 530 is embedded in the first groove 510 of the adjacent second frame 220, and the wide part 520 is inserted into the insertion interface 540 of the adjacent first frame 120. Since the bottom width of the wide part 520 is smaller than the insertion interface 540, and the top width is larger than the insertion interface 540, the cross-section of the wide part 520 has a trapezoidal structure. Figure 7 As shown, during the pressing process, the insertion interface 540 elastically opens to allow the wide body portion 520 to enter the inner side. After pressing and embedding, the wide body portion 520 can descend vertically into the inner side of the first groove 510, ultimately forming a structural interference that prevents it from coming out along the lateral tensile direction, such as... Figure 2 , 7 As shown. Thus, multiple inoculation racks are rigidly connected in series laterally. The impact force of the lateral water flow on a single inoculation rack is transmitted to adjacent inoculation racks through the rigid fastener 500, and is shared by the series, reducing the probability of a single inoculation rack shifting or overturning in the water flow; During disassembly, the first frame 120 can be directly disassembled, and then the adjacent second frame 220 can be disassembled and separated based on the rigid fastener 500.

[0029] In an optional embodiment of this application, such as Figure 8As shown, the flexible buckle 600 includes an axial portion 620, a protrusion 630, and a groove 640 extending from the middle side of the protrusion 630 to the inner side of the axial portion 620. The protrusion 630 is located at one end of the axial portion 620. The diameter of the axial portion 620 is less than or equal to that of the second groove 610, and the diameter of the protrusion 630 is greater than that of the axial portion 620.

[0030] The flexible fastener 600 and the second groove 610 constitute a longitudinal splicing structure for adjacent inoculation racks. Unlike the interlocking and anti-detachment principle of the rigid fastener 500, the flexible fastener 600 relies on material elasticity to achieve locking. The groove 640 extends from the middle of the protrusion 630 into the axial portion 620, giving the protrusion 630 an elastic space to contract inward when subjected to radial compression. During splicing, the protrusion 630 is pressed into the second groove 610. It is compressed and contracts as it passes through the groove, and returns to its original shape under the action of material elasticity after passing through. The portion with an outer diameter larger than the second groove 610 prevents it from reversing outward. In underwater operations, the insertion can be completed manually by feel, without the need for auxiliary tools. The elastic space provided by the groove 640 can absorb some of the vibration energy when the inoculation rack is subjected to water flow vibrations, buffering the impact load on the flexible fastener 600 and reducing the risk of fatigue fracture.

[0031] In an optional embodiment of this application, the protrusion 630 is frustum-shaped, the outer diameter of the protrusion 630 near the axial portion 620 is larger than the second groove 610, and the outer diameter of the protrusion 630 away from the axial portion 620 is smaller than the second groove 610.

[0032] It is understood that the outer diameter of the frustum-shaped protrusion 630 gradually increases from the insertion end to the locking end. The smaller outer diameter of the insertion end acts as a guide, resulting in lower insertion resistance. The larger outer diameter of the locking end forms a stepped stop surface after passing through the second groove 610, preventing reverse dislodgement and providing higher resistance to dislodgement. Thus, the asymmetrical cross-sectional shape of the protrusion 630 achieves a balance between low assembly force in the insertion direction and high resistance to dislodgement in the extraction direction.

[0033] In an optional embodiment of this application, both the upper space frame 110 and the lower space frame 210 are triangular frame structures, and the ends of the triangular frame are provided with support nodes. The support nodes are also distributed on the middle side of the first frame 120 and the second frame 220.

[0034] The triangular frame structure refers to the triangular shape of the mesh units of the upper mesh frame 110 and the lower mesh frame 210, utilizing the inherent stability of the triangular geometry to resist torsional deformation within the mesh plane. The support nodes are located at the intersection of the vertices of the triangular meshes, forming a three-dimensional structure protruding from the mesh surface. During its growth stage, sea grapes attach to the contact surface through downward-growing capillary rhizoids to achieve fixation. The support nodes distributed on the mesh surface provide three-dimensional anchor points for the rhizoids, allowing them to wrap around the nodes to form a mechanical lock, enhancing the algae's resistance to water flow drag and promoting faster colonization after inoculation.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
