Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, in particular to a tension-type grouting-free connection anchoring system. Background Art

[0002] With the country's strong support for the construction of "blue granaries", offshore aquaculture will become a key development direction. However, whether the traditional cages are fixed by anchoring or pile anchoring, the cables and cages in these anchoring forms are inclined at a certain angle, with a large anchoring radius and a large sea area. The cables are far beyond the range of the cages and are located underwater. Even if anchor buoys are set, there is still a risk of being cut off by passing ships and dragging anchors due to difficulty in observation. In addition, in the traditional anchoring structure, piles and sleeves are usually connected by grouting, which not only requires a large amount of grouting raw materials, but also requires a lot of working time for offshore grouting operations, resulting in high offshore construction costs and poor overall project economy. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a tensioned grouting-free connection anchoring system, which can not only avoid offshore grouting operations, shorten offshore installation operation time, reduce offshore construction costs, and improve the overall economy of the project, but also reduce the risk of cables being cut by passing ships, etc., thereby greatly improving the overall safety of the cage.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0005] A tension-type grout-free connection anchoring system, comprising a main frame, a sleeve, a pile column, an anchor point module and a limit locking module;

[0006] Wherein, the sleeve is connected to the main frame, and a lower ring plate is provided on the top of the outer side of the sleeve;

[0007] The pile column is arranged in the sleeve, and an upper ring plate is arranged on the outer side of the pile column;

[0008] The bottom of the upper ring plate contacts the top of the sleeve and the lower ring plate, and the upper ring plate and the lower ring plate are locked in a limited position by a limited locking module;

[0009] The anchor module is connected between the net box and the main frame.

[0010] In this technical solution, when the main frame moves upward due to the movement of the cage, the upper ring plate on the outside of the pile column directly presses the lower ring plate on the outside of the sleeve, thereby limiting the upward movement of the main frame; when the main frame moves downward, the upper and lower ring plates are locked due to the limit locking effect of the limit locking module, thereby limiting the downward movement of the main frame; therefore, the entire anchoring system stands on the seabed through the connection of the above parts. By using this anchoring system, the grouting connection between the traditional pile column and the sleeve is avoided, the offshore grouting operation is eliminated, the offshore operation time is shortened, and the cost of grouting materials is saved while reducing the offshore installation cost.

[0011] Furthermore, the main frame includes an inner ring tube, an outer ring tube, and a connecting tube;

[0012] The outer ring tube is arranged on the periphery of the inner ring tube;

[0013] The connecting pipe is connected between the outer ring pipe and the inner ring pipe, and forms a truss structure with the outer ring pipe and the inner ring pipe;

[0014] The sleeve is connected to the inner ring tube;

[0015] The anchor point module is connected between the net box and the outer ring tube.

[0016] In the technical solution, the connecting pipe is connected between the outer ring pipe and the inner ring pipe, and forms a truss structure with the outer ring pipe and the inner ring pipe, which can improve the overall strength of the main frame and further improve the ability to resist external loads.

[0017] Furthermore, the shape of the outer ring tube is consistent with the shape of the bottom of the cage;

[0018] The anchor point module includes an anchor point unit and a cable;

[0019] One end of the cable is connected to the bottom of the net box, and the other end is connected to the outer ring tube through the anchor unit. When the cable is in a tensioned state, the bottom of the net box faces the outer ring tube.

[0020] In this technical solution, the shape of the outer ring tube is consistent with the shape of the bottom of the cage. When the cable is in a tensioned state, the bottom of the cage faces the outer ring tube, so that the radius of the anchor point module on the anchoring system is only equivalent to the size of the cage, thereby avoiding the problem of excessive anchor radius of traditional cages and the interference of anchor cables of adjacent cages, thereby enabling more cages to be deployed in the same sea area or a smaller sea area to be used when the same number of cages are deployed, thereby improving the utilization rate of the sea area and reducing the cost of using the sea, thereby reducing the cost of project development and improving the economic efficiency of the project. At the same time, since the cables are arranged within the cage range and do not spread outside the cage range, they are easy to identify on the sea surface, thereby greatly reducing the risk of the cables being cut by passing ships, etc., and greatly improving the overall safety of the cage.

[0021] Further, the anchor point unit comprises an anchor point lifting lug and a connecting shackle;

[0022] The anchor point lifting lug is connected to the outer ring tube;

[0023] The cable is connected to the anchor point lifting lug via a connecting shackle.

[0024] Furthermore, the anchor point lifting lug is provided with a reinforcing rib for strengthening the connection between the anchor point lifting lug and the outer ring tube.

[0025] Furthermore, a guide plate is provided in the sleeve, so that the pile column can pass through the sleeve easily through the guide plate when driving the pile.

[0026] Furthermore, a reinforcing ring plate connected between the sleeve and the guide plate is provided in the sleeve, which not only strengthens the sleeve pipe node but also transfers the horizontal load on the main frame to the pile column.

[0027] Further, the limit locking module includes a U-shaped limit locking plate and a bolt;

[0028] The outer ends of the upper ring plate and the lower ring plate are both inserted into the inner side of the U-shaped limiting locking plate, and the U-shaped limiting locking plate limits and locks the relative position between the upper ring plate and the lower ring plate;

[0029] The bolt cooperates with the U-shaped limiting locking plate to ensure the locking force.

[0030] Furthermore, the limiting and locking modules are evenly arranged along the circumferential direction of the upper ring plate, and the relative position between the upper ring plate and the lower ring plate can be limited and locked by cooperating with a plurality of evenly arranged limiting and locking modules.

[0031] Compared with the prior art, the principles and advantages of this technical solution are as follows:

[0032] 1. In this technical solution, when the main frame moves upward due to the movement of the cage, the upper ring plate on the outside of the pile column directly presses the lower ring plate on the outside of the sleeve, thereby limiting the upward movement of the main frame; when the main frame moves downward, the upper and lower ring plates are locked due to the limit locking effect of the limit locking module, thereby limiting the downward movement of the main frame; therefore, the entire anchoring system stands on the seabed through the connection of the above parts. By using this anchoring system, the grouting connection between the traditional pile column and the sleeve is avoided, the offshore grouting operation is eliminated, the offshore operation time is shortened, and the cost of grouting materials is saved while reducing the offshore installation cost.

[0033] 2. In this technical solution, the shape of the outer ring tube is consistent with the shape of the bottom of the cage. When the cable is in a tensioned state, the bottom of the cage faces the outer ring tube, so that the radius of the anchor point module on the anchoring system is only equivalent to the size of the cage, thereby avoiding the problem of excessive anchor radius of traditional cages and the interference of anchor cables of adjacent cages, thereby enabling more cages to be deployed in the same sea area or a smaller sea area to be used for the same number of cages, thereby improving sea area utilization and reducing sea use costs, thereby reducing project development costs and improving project economics. At the same time, since the cables are arranged within the cage range and do not spread outside the cage range, they are easy to identify on the sea surface, thereby greatly reducing the risk of the cables being cut by passing ships, etc., and greatly improving the overall safety of the cage.

[0048] The limiting and locking module 5 includes a U-shaped limiting and locking plate 18 and a bolt 19 .

[0049] The main frame 1 includes an inner ring tube 9, an outer ring tube 10, and a connecting tube 11; the outer ring tube 10 is arranged on the periphery of the inner ring tube 9; the connecting tube 11 is connected between the outer ring tube 10 and the inner ring tube 9, and forms a truss structure with the outer ring tube 10 and the inner ring tube 9.

[0050] The sleeve 2 is connected to the inner ring tube 9, and a lower ring plate 6 is provided on the outer top of the sleeve 2; the pile column 3 is arranged in the sleeve 2, and an upper ring plate 7 is provided on the outer side of the pile column 3; the bottom of the upper ring plate 7 is in contact with the top of the sleeve 2 and the lower ring plate 6, and the outer ends of the upper ring plate 7 and the lower ring plate 6 are both inserted into the inner side of the U-shaped limiting locking plate 18, and the relative position between the upper ring plate 7 and the lower ring plate 6 is limited and locked by the U-shaped limiting locking plate 18; the limiting locking modules 5 are evenly arranged along the circumferential direction of the upper ring plate 7; the bolts 19 cooperate with the U-shaped limiting locking plate 18 to ensure the locking force.

[0051] Specifically, in this embodiment, the shape of the outer ring tube 10 is consistent with the shape of the bottom of the net box 8; the anchor module 4 includes an anchor unit and a cable 12; one end of the cable 12 is connected to the bottom of the net box 8, and the other end is connected to the outer ring tube 10 through the anchor unit, and when the cable 12 is in a tensioned state, the bottom of the net box 8 faces the outer ring tube 10.

[0052] Specifically, in this embodiment, the anchor unit includes an anchor lug 13 and a connecting shackle 14; the anchor lug 13 is connected to the outer ring tube 10; the cable 12 is connected to the anchor lug 13 via the connecting shackle 14.

[0053] Specifically, in this embodiment, a guide plate 16 and a reinforcing ring plate 17 connected between the sleeve 2 and the guide plate 16 are provided in the sleeve 2 .

[0054] The principles of this embodiment are as follows:

[0055] When the main frame 1 moves upward due to the movement of the cage 8, the upper ring plate 7 on the outside of the pile column 3 directly presses the lower ring plate 6 on the outside of the sleeve 2, thereby limiting the upward movement of the main frame 1; when the main frame 1 moves downward, the upper ring plate 7 and the lower ring plate 6 are limited and locked due to the limit locking effect of the limit locking module 5, thereby limiting the downward movement of the main frame 1; and the lateral sliding of the main frame 1 is limited by the contact between the reinforcing ring plate 17 in the sleeve 2 and the pile column 3.

When the cable 12 is in a tensioned state, the bottom of the net box 8 is facing the outer ring tube 10, so that the arrangement radius of the anchor point module 4 on the anchoring system is only equivalent to the size of the net box 8, thereby avoiding the problem of the traditional net box 8 anchoring radius R being too large, and avoiding the problem of interference between the anchor cables of adjacent net boxes 8, thereby enabling more net boxes 8 to be deployed under the same sea area or a smaller sea area to be used when the same number of net boxes 8 are deployed, thereby improving the utilization rate of the sea area and reducing the cost of using the sea, thereby reducing the project development cost and improving the economic efficiency of the project. At the same time, since the cables 12 are all arranged within the range of the net box 8 and do not spread outside the range of the net box 8, they are easy to identify on the sea surface, thereby greatly reducing the risk of the cables 12 being cut by passing ships, etc., and greatly improving the overall safety of the net box 8.

[0058] The anchor point lifting lug 13 is provided with a reinforcing rib 15 to strengthen the connection between the anchor point lifting lug 13 and the outer ring tube 10 .

[0059] A guide plate 16 is arranged in the sleeve 2 so that the pile column 3 can pass through the sleeve 2 easily through the guide plate 16 when driving the pile.

[0060] A reinforcing ring plate 17 connected between the sleeve 2 and the guide plate 16 is provided in the sleeve 2 , which not only strengthens the pipe node of the sleeve 2 but also transfers the horizontal load on the main frame 1 to the pile column 3 .

[0061] The limiting and locking modules 5 are evenly arranged along the circumferential direction of the upper ring plate 7 .
