Description

Technical Field

[0001] The invention relates to the technical field of seawater aquaculture, in particular to a transparent sea cucumber seedling cultivation attachment device. Background Art

[0002] Existing factory-based sea cucumber seedling nurseries typically use a two-part substrate: a semi-open polyethylene mesh frame and multiple corrugated polyethylene sheets. The polyethylene sheets have poor permeability, hindering water exchange and the removal of metabolites from the sea cucumber seedlings. Furthermore, the process requires disassembly, washing, and inserting the sheets into the frame, making the process complex. To this end, existing technologies, such as Chinese invention patent publication number CN106234279A, disclose a factory-based attachment base for sea cucumber seedlings and juvenile sea cucumbers. The base comprises nets, floats, and thin nylon ropes. Furthermore, the ropes are nylon rope-like structures connected end-to-end to form a rectangle. Several nets are fixedly attached to a pair of long sides of the rectangle formed by the ropes at intervals. The nets are rectangular mesh structures woven from nylon ropes. The two endpoints of one side of the net are fixedly attached to a pair of long sides of the rectangle formed by the ropes. The plane of the net is perpendicular to the pair of long sides of the rectangle formed by the ropes. The nets are fixedly connected to adjacent nets with thin nylon ropes. Several floats are fixedly attached to the ropes at intervals. However, because the ropes are connected by thin nylon ropes, which have little stiffness, the ropes on adjacent ropes may stick together under the impact of water flow in the nursery pond, affecting the attachment of juvenile sea cucumbers. Summary of the Invention

[0003] In order to overcome the defects of the prior art, the present invention provides a transparent sea cucumber seedling cultivation attachment device, the technical solution adopted is:

[0004] A transparent sea cucumber seedling cultivation attachment device, comprising

[0005] Two plastic U-shaped rods, with multiple special-shaped holes evenly arranged on the inner vertical plate of the U-shaped rod. The special-shaped holes are formed by merging circular holes and rectangular holes. The rectangular holes pass through the upper end surface of the inner vertical plate; multiple clamps are evenly arranged on the lower surface of the bottom plate of the U-shaped rod;

[0006] A plurality of meshes, the number of which matches the number of the irregularly shaped holes, comprises a rectangular frame made of plastic material, the lower frame strips of the rectangular frame extending to both sides to form frame hinges, and a plastic mesh having a corresponding profile to the rectangular frame being fixedly connected to one side of the rectangular frame; the thickness of the meshes is equal to or slightly less than the width of the rectangular holes, and the length of the frame hinge is less than the width of the inner cavity of the U-shaped rod;

[0007] Multiple rubber bands, the number of which is the same as the number of the clamps, the length of which in a free state is smaller than the width of the mesh, are hung on the clamps corresponding to the two U-shaped rods respectively.

[0008] Compared with the prior art, the present invention has a unique structure and uses extremely simple materials. It can be folded together to save space during transportation. When in use, it can ensure that adjacent meshes are fixed in position and stand still. It is easy to operate and saves manpower and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-13 The transparent sea cucumber seedling cultivation attachment device shown includes:

[0024] Two U-shaped rods 1 made of PVC material, with 16 evenly spaced special-shaped holes 11 on the inner vertical plate of the U-shaped rod 1. The special-shaped holes 11 are formed by merging a circular hole 111 and a rectangular hole 112. The rectangular hole 112 passes through the upper end surface of the inner vertical plate; six evenly spaced clips 12 are provided on the lower surface of the bottom plate of the U-shaped rod 1;

[0025] 16 mesh panels 2, including a rectangular frame 21 made of PVC, with the lower frame strips of the rectangular frame 21 extending to both sides to form frame hinges 211. One side of the rectangular frame 21 is fixedly connected to a plastic mesh 22 made of PE material with a similar profile. The thickness of the mesh panel 2 is slightly smaller than the width of the rectangular hole 112, and the length of the frame hinge 211 is half the length of the inner cavity of the U-shaped rod 1.

[0026] Six rubber bands 3, each with a length equal to half the width of the mesh 2 in its free state, are respectively hung on the six clips 12 corresponding to the two U-shaped rods 1. In another preferred embodiment, if the elastic force of the rubber bands 3 is still weak, the four rubber bands 3 in the middle can be cross-hooked in an "X" shape.

[0027] In this embodiment, the mesh size of the plastic net 22 is 80 meshes, and a plastic net size of 200 meshes to 40 meshes can be selected according to the different ages of the young ginseng.

[0028] In this embodiment, the cross-section of the frame hinge 211 is rectangular, and the diameter of the circumscribed circle of the rectangular cross-section is slightly smaller than the diameter of the circular hole 111. In another preferred embodiment, the cross-section of the frame hinge 211 is circular, but it is obvious that the solution of this embodiment is simpler and more reasonable.

[0029] In this embodiment, the clamping head 12 is a stepped truncated cone with a larger outer diameter and a smaller inner diameter, and is integrally injection-molded with the U-shaped rod 1. In another preferred embodiment, the clamping head 12 is a plastic screw that is screwed into a screw hole defined in the bottom plate of the U-shaped rod 1. In another preferred embodiment, the clamping head 12 is a plastic rivet that is riveted into a rivet hole defined in the bottom plate of the U-shaped rod 1. In another preferred embodiment, the clamping head 12 is a plastic bayonet that is engaged with a bayonet hole defined in the bottom plate of the U-shaped rod 1.

[0030] In this embodiment, the rectangular frame 21 and the plastic mesh 22 are heat-fused together. In another preferred embodiment, the rectangular frame 21 and the plastic mesh 22 are bonded together using an adhesive. In another preferred embodiment, an annular groove is provided on one side of the rectangular frame 21, and a rubber bead is pressed into the annular groove across the plastic mesh 22, thereby securing the rectangular frame 21 and the plastic mesh 22 together.

[0031] like Figure 5-8 As shown, this sea cucumber seedling cultivation attachment device is produced by a professional injection molding manufacturer. During assembly, 16 mesh sheets 2 are directly stacked together, and the frame hinges 211 at both ends of the mesh sheets 2 are inserted into the 16 special-shaped holes 11 of the two U-shaped rods 1. The outer end faces of the left and right frame strips of the mesh sheets 2 are ensured to abut the inner end faces of the inner vertical plates of the U-shaped rods 1. Then, at least two rubber bands 3 are hung on the two corresponding clamps 12 of the two U-shaped rods 1. The elastic force of the rubber bands 3 restrains the two U-shaped rods 1 and the 16 mesh sheets 2 together, forming a flat plate. Multiple sea cucumber seedling cultivation attachment devices can be stacked together for packaging and shipment. This is very space-saving and very convenient to assemble.

[0032] like Figure 9-13 As shown, when the flat-plate sea cucumber seedling cultivation attachment device is obtained at the nursery, the user can grasp the middle of the two U-shaped rods 1 with both hands, with the bottom plate end of the U-shaped rod 1 facing upwards, and then apply force outwards with both hands to slightly separate the two U-shaped rods 1. At this time, the 16 mesh sheets 2 are not constrained and are turned downwards with their respective frame pivots 211 as the rotation axis. Finally, the 16 mesh sheets 2 are in a vertical state. At this time, the user lets go and removes the outward supporting force with both hands so that the two U-shaped rods 1 are close to each other. Since the thickness of the mesh 2 is equal to or slightly smaller than the width of the rectangular holes 112, the left and right frame strips of the 16 meshes 2 can be respectively inserted into the special-shaped holes 11 of the two U-shaped rods 1 until the free ends of the frame hinges 211 abut against the inner surfaces of the outer uprights of the U-shaped rods 1. At this point, the left and right frame strips of the mesh 2 are stuck in the rectangular holes 112, making the mesh 2 fixed and unable to shake. At this time, the elastic force of the rubber bands 3 keeps the two U-shaped rods 1 and the 16 meshes 2 in this state. Therefore, it is very simple and quick to use.

[0033] The elastic force of the rubber band 3 constrains the two U-shaped rods 1 and the 16 mesh pieces 2 together, forming a flat plate. Multiple sea cucumber seedling cultivation attachment devices can be stacked together for storage, which is very convenient.
