Description

Technical Field

[0001] This application relates to the field of anti-torsion technology, such as an anti-torsion device and a polar buoy assembly. Background Technology

[0002] The Earth's North and South Poles contain abundant resources.

[0003] During polar exploration, in addition to observing the ocean surface and atmospheric environment, many specific polar exploration devices, such as polar buoys, need to penetrate the ice layer and penetrate underwater for observation. The hull and sensors deployed beneath the polar buoy are usually connected by cables. However, the complex conditions in polar waters, such as ice floes colliding, strong currents, and freezing temperatures, can easily cause the buoy cables to twist. This twisting not only disrupts the installation posture of the observation equipment on the buoy, leading to a decrease in the reliability and accuracy of the observation data, but also causes fatigue damage to the cables and the buoy itself due to the continuous torsional force, shortening the lifespan of both the polar buoy and the sensors.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0027] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] Combination Figures 1 to 3 As shown, this embodiment of the disclosure provides an anti-torsion device, including: a flange 10 and multiple connecting rods 20. The flange 10 can be connected to the bottom of a polar buoy. The multiple connecting rods 20 are connected end to end to form a long chain structure. The first connecting rod 20 is hinged to the flange 10, and adjacent connecting rods 20 are hinged to each other. That is, the first connecting rod 20 can rotate relative to the flange 10, and the connecting rods 20 can also rotate relative to each other. However, each connecting rod 20 can only move within a predetermined range within the same plane.

[0030] Combination Figure 4 As shown, in use, first connect the flange 10 to the bottom of the polar buoy's hull 30, and then tie the cable between the polar buoy and the sensor to each section of the connecting rod 20. Then, lower the multiple sections of the connecting rod 20 into the water 3 below the ice layer 1 through the ice hole 2, with the hull 30 positioned above the ice layer 1.

[0031] The anti-torsion device provided in this embodiment allows the flange 10 to be connected to the bottom of the hull 30 of the polar buoy. Multiple connecting rods 20 are sequentially hinged to form a long chain structure, with the first connecting rod 20 hinged to the flange 10. Each connecting rod 20 can only move within a preset range on the same plane. In use, the cable between the polar buoy and the sensor is bound to each connecting rod 20, effectively limiting the cable's range of motion and preventing cable torsion due to ice floe collisions, strong ocean currents, or low-temperature freezing, thus protecting the safety of the polar buoy and the sensor.

[0032] Optionally, the number of connecting rod sections 20 can be increased or decreased according to the thickness of ice layer 1 and the required observation depth.

[0033] Optionally, the anti-torsion device further includes multiple couplings 40. The first connecting rod 20 is hinged to the flange 10 via a coupling 40. Two adjacent connecting rods 20 are hinged to each other via a coupling 40. The couplings 40 ensure that each connecting rod 20 can only move within a predetermined range in the same plane.

[0034] Optionally, see Figure 5 and Figure 6 The coupling 40 includes an outer coupling 41 and an inner coupling 42. The outer coupling 41 is connected to the first end of the connecting rod 20. Figure 1(As shown on the left end). For the coupling 40 used to connect the flange 10 and the first connecting rod 20, its inner coupling 42 is connected to the flange 10; for the coupling 40 used to connect the two connecting rods 20, its inner coupling 42 is connected to the second end of the corresponding connecting rod 20. Figure 1 (As shown on the right end). That is, for a section of connecting rod 20, the first end of connecting rod 20 is connected to the outer coupling 41, and the second end of connecting rod 20 is connected to the inner coupling 42. The outer coupling 41 is rotatably connected to the inner coupling 42 connected to it. The rotatable planes of each outer coupling 41 are the same. In this way, torsion can be avoided.

[0035] Optionally, the internal coupling 42 is rotatably connected to the external coupling 41 via a first screw 50. Specifically, corresponding portions of the internal coupling 42 and the external coupling 41 have threaded holes, and the first screw 50 is threaded into these holes. Optionally, a screw with a slightly smaller diameter can be used to connect the internal coupling 42 and the external coupling 41, and it should not be tightened too much to reduce the friction between the internal and external couplings, thereby enabling relative rotation between them. Bolts, pins, or other structures can also be used instead of the first screw 50.

[0036] Optionally, see again Figure 5 and Figure 6 The external coupling 41 includes a first insertion portion 411 and a clamping portion 412. The first end of the first insertion portion 411 is inserted into the first end of the corresponding connecting rod 20 along its axial direction. Specifically, the first end of the connecting rod 20 has a first insertion hole along its own axial direction, and the first end of the first insertion portion 411 is inserted into the first insertion hole. The bottom of the clamping portion 412 is connected to the second end of the first insertion portion 411. Simultaneously, the top of the clamping portion 412 has a groove penetrating the thickness direction of the clamping portion 412, thereby forming two opposing connecting ears 413. The internal coupling 42 is disposed within the groove, thereby clamping the two connecting ears 413 on both sides of the internal coupling 42. The two connecting ears 413 are rotatably connected to the internal coupling 42.

[0037] Optionally, the first insertion part 411 is connected to the first end of the corresponding connecting rod 20 by a second screw 60. Specifically, a threaded hole is provided on the wall surface of the first insertion part 411 near its first end, corresponding to the wall surface of the first insertion hole, and the second screw 60 is threaded into the threaded hole.

[0038] Optionally, the first insertion part 411 and the clamping part 412 are integrally formed.

[0039] Optionally, see again Figures 1 to 6The internal coupling 42 includes a second insertion portion 421 and a connecting portion 422. For a coupling 40 used to connect the flange 10 and the first connecting rod 20, where the internal coupling 42 is connected to the flange 10, the second insertion portion 421 is also connected to the flange 10. For a coupling 40 used to connect two connecting rods 20, where the internal coupling 42 is connected to the second end of the corresponding connecting rod 20, the first end of the second insertion portion 421 is inserted into the second end of the corresponding connecting rod 20 along its axial direction. The bottom of the connecting portion 422 is connected to the second end of the second insertion portion 421, and the connecting portion 422 is rotatably connected to the corresponding external coupling 41, i.e., located within a groove and connected to two connecting ears 413.

[0040] Optionally, the second end of the connecting rod 20 is provided with a second insertion hole, and the second insertion part 421 is inserted into the second insertion hole. The wall surface of the second insertion part 421 near its first end is provided with a threaded hole at a position corresponding to the wall surface of the second insertion hole, and the third screw 70 is threaded into the threaded hole.

[0041] Optionally, the second insertion part 421 and the connecting part 422 are integrally formed.

[0042] See you again Figure 3 This disclosure provides a polar buoy assembly, including a polar buoy and an anti-torsion device as described above. The polar buoy includes a hull 30. A flange 10 of the anti-torsion device is connected to the bottom of the hull 30. The hull 30 is connected to a sensor via cables, which are bound to connecting rods 20 of the anti-torsion device. The connecting rods 20 can only move within a predetermined range on the same plane, thus preventing the cables from twisting.

[0043] Optionally, the bottom of the hull 30 is welded to the flange 10.
