Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mariculture net cage, especially relates to a net cage anchoring float pipe structure. BACKGROUND

[0002] With the development and utilization of coastal aquaculture waters, the mariculture net cage has become an important aquaculture tool. The float pipe in the mariculture net cage is an important component for supporting the net cage structure and providing buoyancy, and usually needs to use the binding rope anchoring method to improve the wind and wave resistance of the net cage. When the mariculture net cage encounters extreme weather such as large-scale typhoon, the binding rope anchoring position of the float pipe often breaks, and the main reason is that the tensile force generated by anchoring directly acts on the anchoring position of the float pipe, and the float pipe is a hollow circular pipe structure, and the insufficient rigidity at the anchoring position easily leads to breakage.

[0003] In the prior art, a protective sleeve pipe is added outside the binding rope anchoring position of the float pipe to solve the problem of insufficient rigidity, which can improve the strength and rigidity of the anchoring position to a certain extent, but since the cross-sectional structure of the float pipe is still a hollow circular structure, the inside of the float pipe lacks support, so the improvement effect of strength and rigidity is relatively limited. In addition, the float pipe needs to be fixedly connected using a connecting bracket, and the outer wall of the float pipe is a key part of the connecting bracket and the anchoring system, so adding a protective sleeve pipe outside the binding rope anchoring position of the float pipe reduces the friction force between the inner wall of the protective sleeve pipe and the outer wall of the float pipe due to the smooth connecting surface therebetween, which increases the risk of anchor point deviation, and further may transfer the tensile force of the anchoring rope to the bracket for fixing the float pipe, thereby causing other damage problems. Moreover, since the protective sleeve pipe is sleeved outside the float pipe, when the net cage needs to be maintained, the disassembly and assembly work of the bracket which is also sleeved on the float pipe is affected, and the maintenance is inconvenient.

DETAILED DESCRIPTION

[0033] The embodiments of the utility model are described in detail below, examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0034] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," 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 this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0035] like Figures 1 to 3 As shown, a cage anchoring floating pipe structure includes a floating pipe 1 and an inner support member 2, wherein the inner support member 2 includes an inner support member pipe body 21 and multiple reinforcing ribs 22;

[0036] The inner support tube 21 has a limiting groove 211 on its wall. The limiting groove 211 is recessed relative to the outer wall surface of the inner support tube 21 and faces inward. The groove wall of the limiting groove 211 is enclosed. The float tube 1 has a limiting protrusion 11 on its wall. The limiting protrusion 11 protrudes relative to the inner wall surface of the float tube 1 and faces inward. The shape of the limiting protrusion 11 matches the shape of the limiting groove 211. The limiting protrusion 11 is embedded in the limiting groove 211. The inner support tube 21 is embedded in the float tube 1.

[0037] One end of the reinforcing rib 22 is fixedly connected to the inner wall of the inner support tube 21, and the other end of the reinforcing rib 22 converges at the central axis of the inner support tube 21.

[0038] The inner support 2 is provided with a plurality of reinforcing ribs 22, which are concentrated at the center of the inner support pipe body 21, so as to effectively enhance the rigidity and strength of the inner support 2. The inner support 2 is embedded in the inside of the floating pipe 1, and the position of the inner support 2 is the anchoring point position of the net cage anchoring floating pipe structure. The limiting block 11 is embedded in the limiting groove 211, so as to firmly embed the inner support 2 in the inside of the floating pipe 1. The net cage anchoring floating pipe structure adopts an internally reinforced structure, which fundamentally changes the hollow and lack-of-support structure of the existing floating pipe. At this time, the inner support pipe body 21 is equivalent to a tubular reinforcing layer in the inside of the floating pipe 1, and the reinforcing ribs 22 in the inner support pipe body 21 can provide the effect of enhancing the rigidity and strength, thereby improving the strength and rigidity of the anchoring position of the net cage anchoring floating pipe structure, effectively enhancing the wind and wave resistance of the net cage product, and improving the overall stability and durability of the net cage product. The groove wall of the limiting groove 211 is in a closed shape, which can avoid the rotation or horizontal position deviation of the inner support 2 in the floating pipe, and further ensure the strength and rigidity of the anchoring position of the net cage anchoring floating pipe structure.

[0039] In addition, the net cage anchoring floating pipe structure does not need to additionally provide a sheath pipe outside the floating pipe 1, that is, no other components need to be additionally provided outside the floating pipe 1. This avoids the phenomenon of anchoring point deviation due to the low friction force between the inner wall of the sheath pipe and the outer wall of the floating pipe 1, and facilitates maintenance because the sheath pipe does not need to be provided outside the floating pipe 1.

[0040] The net cage anchoring floating pipe structure can effectively enhance the wind and wave resistance of the net cage product, improve the overall stability and durability of the net cage product, avoid the phenomenon of anchoring point deviation, and facilitate maintenance, thereby solving the technical problems of insufficient strength and rigidity of the anchoring position of the existing net cage floating pipe, easy anchoring point deviation caused by the additional sheath pipe, and inconvenient maintenance.

[0041] Preferably, the floating pipe 1 and the inner support pipe body 21 are respectively in a circular pipe structure, the inner diameter of the floating pipe 1 is greater than the outer diameter of the inner support pipe body 21, the reinforcing ribs 22 are uniformly distributed in a radial manner with the center of the inner support pipe body 21 as the center, and the included angles between adjacent two reinforcing ribs 22 are the same.

[0042] By uniformly distributing the reinforcing ribs 22 radially with the center of the inner support pipe body 21 as the center, the inner support pipe body 21 has the same load bearing capacity in all directions, avoiding damage of the inner support 2 due to insufficient local strength. The uniformly distributed reinforcing ribs 22 can also make the inner support pipe body 21 be able to disperse stress more evenly to the entire inner support 2 when subjected to external force, thereby improving the overall anti-deformation and anti-damage capacity of the inner support 2.

[0043] In an embodiment of the utility model, the reinforcing rib 22 is provided with 8, the included angle between two adjacent reinforcing ribs 22 is 45 °.

[0044] Preferably, the shape of the limiting groove 211 is a racetrack shape.

[0045] The limiting block 11 of the pipe wall of the floating pipe 1 is formed by using a punch to press the pipe material corresponding to the position of the limiting groove 211 into the limiting groove 211, and the limiting block 11 is protrudingly arranged towards the inside of the floating pipe 1 relative to the inner wall of the floating pipe 1 (as shown in the recessed groove shape of the outer wall of the floating pipe 1, as shown in Figure 1 and Figure 2 By setting the shape of the limiting groove 211 as a racetrack shape, the floating pipe 1 can be prevented from being cracked due to stress concentration during stamping and drawing.

[0046] Specifically, the racetrack shape is a rectangular shape with two ends respectively connected with a semicircular shape structure.

[0047] As shown in Figures 3 to 5 Further, the outer wall of the floating pipe 1 is provided with a first positioning groove 12 along the axial direction, the inner wall of the floating pipe 1 is provided with a positioning block 13 at a position corresponding to the first positioning groove 12, and the positioning block 13 is protrudingly arranged towards the inside of the floating pipe 1.

[0048] The outer wall of the inner support pipe body 21 is provided with a second positioning groove 212 along the axial direction, the second positioning groove 212 is matched with the positioning block 13, and the positioning block 13 is embedded in the second positioning groove 212.

[0049] The limiting groove 211 is arranged on the extension line of the second positioning groove 212.

[0050] By setting the first positioning groove 12, the first positioning groove 12 is used for the positioning of the punch in the stamping and drawing process, and the operator can quickly identify and position the first positioning groove 12, thereby simplifying the operation process and improving the work efficiency. By setting the positioning protrusion 13 inside the floating pipe 1 and the second positioning groove 212 on the outer wall of the inner support pipe body 21, the positioning protrusion 13 and the second positioning groove 212 are matched by concave-convex cooperation, and the rotation limiting of the floating pipe 1 to the inner support 2 can be achieved.

[0051] The limiting groove 211 is arranged on the extension line of the second positioning groove 212, and the limiting groove 211 of the inner support 2 corresponds to the first positioning groove 12 of the floating pipe 1, so that the pipe material at the position corresponding to the limiting groove 211 of the floating pipe 1 is pressed into the limiting groove 211 by the punch in the subsequent use, and the limiting protrusion 11 is formed.

[0052] Preferably, the longitudinal section of the first positioning groove 12 is in a semi-elliptical shape.

[0053] The longitudinal section of the first positioning groove 12 is in a semi-elliptical shape, which can facilitate the close fitting of the two side edges of the first positioning groove 12 on the punch for stamping and drawing, and the smooth curve shape of the elliptical groove helps to disperse stress, thereby avoiding the occurrence of single-point stress concentration during the stamping and drawing process, which causes the floating pipe 1 to be cracked.

[0054] Preferably, the limiting groove 211 is located at the middle position of the inner support pipe body 21.

[0055] Further, the inner support pipe body 21 is provided with a magnetic attraction plane 213 at one end face in the axial direction, and the magnetic attraction plane 213 is installed with a magnetic attraction block 2131.

[0056] The net cage anchoring floating pipe structure further comprises a first magnetic attraction positioning block 3 and a second magnetic attraction positioning block 4, the first magnetic attraction positioning block 3 and the second magnetic attraction positioning block 4 are respectively detachably connected with the floating pipe 1, the first magnetic attraction positioning block 3 is arranged on the inner wall of the floating pipe 1, the second magnetic attraction positioning block 4 is arranged on the outer wall of the floating pipe 1, the outer surface of the first magnetic attraction positioning block 3 is provided with a first magnetic attraction surface 31 and a second magnetic attraction surface 32, the first magnetic attraction surface 31 is fitted with the inner wall of the floating pipe 1 and is magnetically attracted to the second magnetic attraction positioning block 4, and the second magnetic attraction surface 32 corresponds to the magnetic attraction block 2131 and is magnetically attracted to the magnetic attraction block 2131.

[0057] When installing the inner support member 2 to the floating tube 1, the position of the anchoring point of the floating tube 1 is planned in advance. Then, a first magnetic positioning block 3 and a second magnetic positioning block 4 are respectively set on the inner and outer walls of the floating tube 1 at the corresponding anchoring point positions. The first magnetic positioning block 3 and the second magnetic positioning block 4 attract each other, aligning the second positioning groove 212 of the inner support member tube body 21 with the positioning protrusion 13 of the floating tube 1 (e.g., Figure 5 As shown), the end of the inner support tube 21 with the magnetic attraction plane 213 is first inserted into the float tube 1. At this time, the positioning protrusion 13 is embedded in the second positioning groove 212. The inner support 2 is pushed towards the first magnetic attraction positioning block 3. The first magnetic attraction positioning block 3 and the magnetic attraction block 2131 on the inner support tube 21 are magnetically attracted. The first magnetic attraction positioning block 3 axially fixes the position of the inner support 2 (e.g., Figure 6 (As shown), the wall surface of the float tube 1 corresponding to the limiting groove 211 is then heated and softened. Next, using the high rigidity of the inner support 2 as a support, a punch is used to press the float tube 1 at the position corresponding to the limiting groove 211 into the limiting groove 211 to form the limiting protrusion 11 (as shown). Figure 7 As shown in the figure, the inner support 2 is firmly embedded inside the floating tube 1, thereby improving the strength and rigidity of the anchorage.

[0058] After the inner support 2 and the float tube 1 are assembled, the second magnetic positioning block 4 is moved away from the inner support 2 on the outer wall of the float tube 1. The second magnetic positioning block 4 drives the first magnetic positioning block 3 to move together and is eventually removed, so that the first magnetic positioning block 3 and the second magnetic positioning block 4 are detachably connected to the float tube 1 respectively.

[0059] Specifically, the magnetic block 2131 is a steel magnetic block, and the magnetic block 2131 can be installed and fixed by setting an installation groove on the magnetic plane 213. The first magnetic positioning block 3 and the second magnetic positioning block 4 can be magnets respectively.

[0060] like Figure 3 As shown, preferably, the magnetic attraction plane 213 is disposed on both sides of one end face of the inner support tube 21 along the axial direction.

[0061] By setting the magnetic attraction plane 213 on both sides of one end face of the inner support tube 21 along the axial direction, a corresponding number of the first magnetic attraction positioning blocks 3 and the second magnetic attraction positioning blocks 4 can be used during installation. Compared with setting the magnetic attraction plane 213 on only one side, the symmetrically arranged magnetic attraction plane 213 can improve the stability of the first magnetic attraction positioning block 3 in axially fixing the position of the inner support 2.

[0062] To further explain, the magnetic suction plane 213 is symmetrically arranged on the inner support tube 21 with respect to the second positioning groove 212;

[0063] The inner support tube 21 has an open receiving cavity 214 corresponding to the magnetic attraction plane 213. The shape of the magnetic attraction plane 213 matches the shape of the first magnetic attraction positioning block 3, and the shape of the receiving cavity 214 matches the shape of the magnetic attraction plane 213. The receiving cavity 214 is used to receive the first magnetic attraction positioning block 3.

[0064] By symmetrically arranging the magnetic suction plane 213 relative to the second positioning groove 212 on the inner support tube 21, the position of the first magnetic suction positioning block 3 placed on the inner wall of the float tube 1 can be easily determined, thereby ensuring the subsequent adsorption of the magnetic suction block 2131.

[0065] Specifically, the accommodating cavity 214 is open in the axial direction of the inner support tube 21 corresponding to the first magnetic positioning block 3, and the accommodating cavity 214 is also open in the radial direction of the inner support tube 21 corresponding to the first magnetic positioning block 3. The magnetic plane 213 is connected to the outside through the accommodating cavity 214. When the first magnetic positioning block 3 adsorbs the magnetic block 2131 on the inner support tube 21, the shape of the magnetic plane 213 matches the shape of the first magnetic positioning block 3, and the shape of the accommodating cavity 214 matches the shape of the magnetic plane 213, so that the first magnetic positioning block 3 can be accommodated in the accommodating cavity 214. When the placement position of the first magnetic positioning block 3 is inaccurate, the first magnetic positioning block 3 cannot enter the accommodating cavity 214, and the position of the first magnetic positioning block 3 needs to be adjusted.

[0066] Preferably, the magnetic attraction plane 213 is D-shaped.

[0067] The D-shaped magnetic attraction plane 213 can adapt to the shape of the inner support tube 21, and compared with the annular inner support tube 21, the D-shaped magnetic attraction plane 213 allows the magnetic blocks 2131 to be arranged in the vertical direction, improving the adsorption accuracy of the first magnetic positioning block 3 when adsorbing the magnetic blocks 2131.

[0068] Specifically, the shape of the first magnetic positioning block 3 matches the shape of the magnetic plane 213, the first magnetic surface 31 of the first magnetic positioning block 3 is in contact with the inner wall of the float tube 1, and the side of the second magnetic positioning block 4 facing the first magnetic positioning block 3 is in contact with the outer wall of the float tube 1.

[0069] To further explain, by setting the limiting groove 211 at the middle position of the inner support tube 21, it is convenient to determine the position of pressing the floating tube 1 corresponding to the position of the limiting groove 211 into the limiting groove 211 to form the limiting protrusion 11. Since the positioning protrusion 13 is embedded in the second positioning groove 212, and the first positioning groove 12 is correspondingly set with the positioning protrusion 13, and the limiting groove 211 is set on the extension line of the second positioning groove 212, when the punch is aligned with the first positioning groove 12, the position of the punch can correspond to the extension line of the second positioning groove 212. Since the first magnetic positioning block 3 axially fixes the position of the inner support 2, and the limiting groove 211 is set at the middle position of the inner support tube 21, it is possible to determine the position where the floating tube 1 needs to form the limiting protrusion 11 (i.e., the position corresponding to the limiting groove 211).

[0070] Furthermore, since the inner support member 2 is provided with multiple reinforcing ribs 22, during subsequent stamping and deep drawing, the reinforcing ribs 22 can provide sufficient support for the inner support member 2, preventing deformation of the inner support member 2 and affecting the stamping and deep drawing process. Specifically, both the float tube 1 and the inner support member 2 are made of HDPE (high-density polyethylene), which has the advantages of being lightweight, having good corrosion resistance, weather resistance, and anti-aging properties.

[0071] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
