Description

Technical Field

[0001] This application relates to the field of polar ice melting technology, for example to a polar ice melting cylinder and ice melting device. Background Technology

[0002] The Earth's North and South Poles are "sacred sites for scientific experiments." Polar expeditions play a vital role in enhancing polar knowledge, protecting the polar ecological environment, rationally utilizing polar resources, and promoting the development of polar industries.

[0003] The detection equipment used in polar expeditions plays a crucial role, with specific equipment needing to penetrate deep into the ice to collect information. First, an ice hole must be drilled in the ice according to the size and shape of the equipment. Then, the equipment is placed into the ice hole and retrieved after an appropriate period of time, as needed.

[0004] Due to the extremely low temperatures in the polar regions, the damaged ice layer will refreeze in a short period of time, making it difficult to retrieve the exploration equipment. Manually breaking through the ice is not only time-consuming and labor-intensive, but may also damage the exploration equipment.

[0029] Combination Figure 1As shown, this embodiment of the present disclosure provides a polar ice-melting cylinder, including: a cylinder body 10, a heating belt 20, and a baffle 30. The cylinder body 10 is a cylindrical body open at both ends. Optionally, the outer diameter of the cylinder body 10 is slightly larger than the outer diameter of the detection device. Two insertion holes symmetrical about the central axis of the cylinder body 10 are opened on the outer wall of the cylinder body 10. The heating belt 20 is coiled on the outer wall of the cylinder body 10, and the top end 21 of the heating belt 20 can be extended to connect to an external power source for ice melting. The bottom end 22 of the heating belt 20 is a closed end. The baffle 30 can be inserted into the two insertion holes. Optionally, the insertion holes are located near the top end of the cylinder body 10 so that most of the cylinder body 10 can be placed in a pre-drilled ice hole 50, improving the ice melting effect.

[0030] Combination Figure 2 As shown, during use, first, an ice hole 50 is drilled in the ice layer 40 according to the size of the detection equipment. Then, the detection equipment is lowered into the water below the ice layer 40 through the ice hole 50. The polar ice-melting cylinder is placed inside the ice hole 50, and a lifting device can be used to suspend the polar ice-melting cylinder inside the ice hole 50. Then, the power is turned on, and the heating belt 20 is energized to continuously heat the ice layer 40 around the polar ice-melting cylinder to melt the ice. After the detection work is completed, first remove the detection equipment, then turn off the power, and finally remove the polar ice-melting cylinder.

[0031] The polar ice-melting cylinder provided in this embodiment has openings at both ends of the cylinder body 10 for easy access to the detection equipment. Two symmetrical insertion holes are provided on the outer wall of the cylinder body 10, into which the retaining rod 30 can be inserted. When the heating belt 20 is energized, it heats the ice layer 40 surrounding the cylinder body 10, thereby melting the ice and allowing for easier removal of the detection equipment after use. This not only saves labor and time but also protects the detection equipment, helping to improve the efficiency of polar expeditions and reduce the burden on the team.

[0032] Optionally, the outer surface of the cylinder 10 is coated with an anti-icing layer to further prevent icing.

[0033] Optionally, the heating band 20 is wound from the top to the bottom of the outer wall of the cylinder 10 and arranged in a multi-S shape. In this way, the heating band 20 covers the entire outer wall of the cylinder 10, providing a larger heating area for the ice layer 40 and improving the ice melting effect.

[0034] Optionally, the bending distance when the heating belt 20 is wound is appropriate to ensure that the heating area is uniform and sufficient.

[0035] Optionally, the heating band 20 is fixed to the outer wall of the cylinder 10 by a plurality of first snap-fit ​​structures 60 to prevent the heating band 20 from falling off. Optionally, the first snap-fit ​​structures 60 are evenly arranged along the trajectory where the heating band 20 needs to be wound.

[0036] Optionally, combined Figure 3As shown, the first snap-fit ​​structure 60 includes a first snap-fit ​​61 and a first engaging portion 62 disposed on the outer wall of the cylinder 10. The first snap-fit ​​61 and the first engaging portion 62 engage to fix the heating band 20.

[0037] See you again Figure 3 The first buckle 61 includes: a first connecting plate 611, a first connecting strap 612, and a first protrusion 613. The first connecting plate 611 is fixedly disposed on the outer wall of the cylinder 10. The first end of the first connecting strap 612 ( Figure 3 The upper end shown is connected to the first connecting plate 611. The bottom of the first protrusion 613 is connected to the second end of the first connecting band 612. Figure 3 The lower end shown is connected to the first protrusion 613, and the two sides of the first protrusion 613 are respectively provided with outwardly inclined first elastic locking portions 614. Specifically, the first end of the first elastic locking portion 614 ( Figure 3 The lower end shown is connected to the side of the top of the first protrusion 613, and the second end of the first elastic locking part 614 ( Figure 3 The upper end shown is a free end and has a preset distance from the first protrusion 613.

[0038] See you again Figure 3 The first engaging portion 62 includes: a second connecting plate 621, a second connecting strip 622, and a first connecting portion 623. The second connecting plate 621 is disposed on the outer wall of the cylinder 10 and corresponds to the first connecting plate 611. The first connecting plate 611 and the second connecting plate 621 are respectively disposed on both sides of the heating strip 20 in the width direction. The first end of the second connecting strip 622 ( Figure 3 The lower end shown is connected to the second connecting plate 621. The first end of the first connecting part 623 (shown below) is connected to the second connecting plate 621. Figure 3 The lower end shown) and the second end of the second connecting band 622 ( Figure 3 The first connecting part 623 is connected to the upper end shown, and a first slot 624 is provided in the first connecting part 623. The first elastic locking part 614 is locked in the first slot 624, thereby realizing the first buckle 61 and the first engaging part 62 engaging.

[0039] Optionally, see again Figure 3 The first slot 624 includes: a first groove 625 and a second groove 626. From the second end of the first connecting portion 623 ( Figure 3As shown at the upper end, that is, starting from the end facing the first protrusion 613, a first groove 625 and a second groove 626 are sequentially recessed into the interior of the first connecting portion 623. The width of the second groove 626 is greater than the width of the first groove 625, forming a step 627 at the connection between the second groove 626 and the first groove 625. When the first buckle 61 engages with the first engaging portion 62, the first elastic engaging portion 614 is located inside the second groove 626, and the second end of the second elastic engaging portion 722 is engaged at the step 627. In this way, the heating band 20 can be tied to the outer wall of the cylinder 10 using the first buckle 61 and the first engaging portion 62.

[0040] Based on the aforementioned polar ice melting tubes, combined with Figure 4 As shown, this disclosure provides an ice-melting device, which includes multiple sections of polar ice-melting cylinders as described above and a baffle 30. The multiple sections of polar ice-melting cylinders are connected sequentially with the central axis of the cylinder 10 as a common axis, and the baffle 30 can be inserted into the insertion holes of the ice cylinder 10. When the detection equipment is placed into a pre-dug ice hole, the baffle 30 is inserted into two insertion holes of the polar ice-melting cylinder located inside the ice hole, and the two ends of the baffle 30 outside the cylinder 10 rest on the surface of the ice layer, so that the polar ice-melting cylinders inside the ice hole can be cascaded with other polar ice-melting cylinders.

[0041] The ice-melting device provided in this embodiment of the invention uses multiple polar ice-melting cylinders connected coaxially to form a whole, which increases the ice-melting depth, can adapt to different ice thicknesses that need to be melted, and improves the ice-melting efficiency.

[0042] Optionally, two adjacent polar ice melting tubes are detachably connected by multiple second snap-fit ​​structures 70 to facilitate the combination of different numbers of polar ice melting tubes.

[0043] Optionally, combined Figure 5 and Figure 6 As shown, the second snap-fit ​​structure 70 includes: a third connecting strap 71, a second snap 72, and a second engaging portion 73. See again. Figure 1 The bottom and top of the wall of the cylinder 10 are respectively provided with a first connecting hole 11 and a second connecting hole 12. In two adjacent polar ice melting cylinder sections, a third connecting strap 71 passes through the first connecting hole 11 of one polar ice melting cylinder section and the second connecting hole 12 of the other polar ice melting cylinder section. A second buckle 72 is connected to the first end of the third connecting strap 71, and a second engaging part 73 is connected to the second end of the third connecting strap 71. The second buckle 72 and the second engaging part 73 are engaged, thereby connecting the two polar ice melting cylinder sections together. Optionally, there are a total of 6 first connecting holes 11 and 6 second connecting holes 12.

[0044] See you again Figure 5 and Figure 6As shown, the second buckle 72 includes a second protrusion 721. The bottom of the second protrusion 721 is connected to the first end of the third connecting band 71, and second elastic locking portions 722 are respectively provided on both sides of the second protrusion 721. The second engaging portion 73 includes a hollow second connecting portion 731. Second locking grooves 732 are respectively provided on both sides of the outer wall of the second connecting portion 731, and the two second locking grooves 732 are connected to the interior of the second connecting portion 731. When the second buckle 72 and the second engaging portion 73 are engaged, the two second elastic locking portions 722 are respectively engaged in the two second locking grooves 732.

[0045] The second snap-fit ​​structure 70 enables quick connection and disassembly of the two polar ice melting cylinders, thereby improving work efficiency.

[0046] Optionally, the first connecting hole 11 and the second connecting hole 12 are positioned in a one-to-one correspondence to facilitate the connection of the two polar ice melting tube sections.

[0047] Optionally, see again Figure 1 The top of the inner wall of the cylinder 10 is recessed inward to form an annular recess 13, and the bottom of the inner wall of the cylinder 10 is protruded outward to form an annular protrusion 14. When two adjacent polar ice melting cylinders are connected, the annular protrusion 14 of the upper polar ice melting cylinder is engaged with the annular recess 13 of the lower polar ice melting cylinder. When the two polar ice melting cylinders are connected by the second snap-fit ​​structure 70, pre-positioning and pre-insertion can be achieved by the annular protrusion 14 and the annular recess 13, making the connection of the two polar ice melting cylinders more stable and facilitating the installation of the second snap-fit ​​structure 70.

[0048] In use, first, drill an ice hole 50 in the ice layer 40 according to the size of the detection device. Then, place the detection device into the ice hole 50. See also Figure 2 The first section of the polar ice-melting cylinder is placed inside the ice cave 50. The stop bar 30 is inserted into the two holes in the cylinder body 10 of the first section of the polar ice-melting cylinder. The two ends of the stop bar 30 outside the cylinder body 10 rest on the surface of the ice layer 40, thus supporting the first section of the polar ice-melting cylinder inside the ice cave 50. Then refer to... Figure 7 The annular protrusion 14 of the second polar ice melting tube is engaged with the annular recess 13 of the first polar ice melting tube. Then refer to... Figure 8 The bottom of the second polar ice melting cylinder is connected to the top of the first polar ice melting cylinder via the second snap-fit ​​structure 70. The stop bar 30 is inserted into the two insertion holes in the cylinder body 10 of the second polar ice melting cylinder. See also... Figure 9The first polar ice-melting tube's stop bar 30 is pulled out, and the first polar ice-melting tube moves deeper into the ice cave 50 under the influence of gravity. This continues until the second polar ice-melting tube's stop bar 30 rests on the ice layer 40. The third polar ice-melting tube is then connected to the second polar ice-melting tube in the same manner. This method achieves a coaxial connection of multiple polar ice-melting tubes. The heating elements 20 of each polar ice-melting tube are connected to a power source to achieve independent temperature control. Finally, the power is turned on, and each heating element 20 continuously heats the ice layer 40 surrounding the polar ice-melting tube, preventing the ice cave 50 from refreezing. After the exploration work is completed, the exploration equipment is removed first, then the power is turned off, and finally, the polar ice-melting tubes are removed section by section.
