[0026] See also Figures 1 to 4A ballast pipeline leak repair device includes: a plugging piece 100 and a sealing assembly, wherein the plugging piece 100 is used to be welded to the hole in the pipeline, and the plugging piece 100 is provided with a cavity 101; the sealing assembly is built into the cavity 101, and the sealing assembly includes a mounting rod 200, the mounting rod 200 can move relative to the plugging piece 100, the mounting rod 200 can be slidably connected to a telescopic rod group 300, the output end of the telescopic rod group 300 is connected to an elastic bag 400, the elastic bag 400 can be unfolded to form a temporary storage cavity for accommodating water, and one end of the mounting rod 200 is provided with a first limiting The second limiting member 220 is adjustably connected to the blocking member 100. The second limiting member 220 is used to limit the other end of the mounting rod 200 from moving toward the cavity 101. An elastic member 230 is provided between the telescopic rod group 300 and the inner bottom wall of the cavity 101. A limiting structure is provided between the telescopic rod group 300 and the first limiting member 210. The telescopic rod group 300 is used to expand or retract the elastic bag 400 so that the elastic bag 400 blocks the hole in the pipeline.
[0027] The ballast pipeline leak-proof device of the above structure is used by pre-installing the plugging member 100 on the mounting rod 200, and making the first limiting member 210 cooperate with the telescopic rod group 300, and then adjusting the position of the mounting rod 200 according to the size of the hole in the pipeline, and using the second limiting member 220 to limit the movement of the mounting rod 200 into the cavity 101, thereby changing the distance between the first limiting member 210 and the second limiting member 220 to adjust the deformation stroke of the elastic member 230, so that the telescopic rod group 300 is expanded or retracted. The elastic bag 400 is conducive to the elastic bag 400 being able to unfold to form a blocking area suitable for covering the corresponding hole, and then the position of the blocking member 100 is adjusted so that the lower end wall of the blocking member 100 is flush with the elastic bag 400, so that the elastic bag 400 and the blocking member 100 can both be pressed against the pipeline, which is conducive to the elastic bag 400 being able to form an additional temporary storage cavity for leaking water in the cavity 101, thereby preventing the leaking water from affecting the welding of the blocking member 100, and is conducive to improving the effect of the blocking member 100 in repairing the pipeline. Among them, when the first limiter 210 and the second limiter 220 are at a small distance, the telescopic rod group 300 retracts the elastic bag 400, and when the first limiter 210 and the second limiter 220 are at a large distance, the telescopic rod group 300 opens the elastic bag 400.
[0028] See also Figures 2 to 4Furthermore, the blocking member 100 is threadedly connected to the mounting cap 102, the mounting cap 102 is provided with a threaded hole for one end of the mounting rod 200 to pass through, the first stopper 210 is threadedly connected to the mounting rod 200, the mounting cap 102 is provided with an external thread, and the second stopper 220 is provided with an internal thread that can match the external thread. Specifically, through the thread matching method, the installation efficiency of the first stopper 210 and the second stopper 220 can be improved, and it is also beneficial to adjust the position of the first stopper 210 and the second stopper 220 relative to the mounting rod 200, thereby changing the distance between the two to adjust the deformation stroke of the elastic member 230, which is beneficial to drive the elastic member 230 to always be in a compressed state. It is understandable that after the plugging member 100 is welded, the second stopper 220 and the mounting cap 102 can be removed, so that the sealing component can be removed from the threaded hole as a whole outside the plugging member 100, which is conducive to the recovery of the sealing component for reuse, so that the sealing component can be adapted to different sizes of hole repair scenarios, and finally the plugging cap can be set to re-seal the threaded hole. In some embodiments, the plugging member 100 can be a circular tube or a rectangular box with a sealing plate at one end, the threaded hole is opened in the sealing plate, and the mounting cap 102 or a subsequently set plugging cap can be installed at the position of the threaded hole.
[0029] See also Figures 2 to 4 Further, the telescopic rod group 300 includes a mounting block 310 movably arranged on the mounting rod 200, a limiting structure is arranged between the mounting block 310 and the first limiting member 210, the mounting block 310 is rotatably connected to a plurality of first connecting rods 320, one ends of the plurality of first connecting rods 320 are commonly connected to the elastic bag 400, the mounting rod 200 is movably sleeved with a first sleeve 330, a second connecting rod 340 is movably connected between the first connecting rod 320 and the first sleeve 330, the elastic member 230 is connected between the first sleeve 330 and the mounting block 310, and the first sleeve 330 is used to drive the first connecting rod 320 to expand or contract. Specifically, when in use, the first limiting member 210 is first fixed to the mounting rod 200, and the mounting block 310 is fixed to the first limiting member 210 through the limiting structure, and then one end of the mounting rod 200 is driven to move toward the cavity 101, and the first sleeve 330 remains stationary relative to the sealing member 100 under the elastic action of the elastic member 230, so that the first sleeve 330 and the mounting block 310 are separated from each other, and then the second connecting rod 340 drives the first connecting rod 320 to open the elastic bag 400, and finally the elastic bag 400 can be deformed under force to form a temporary storage cavity for accommodating leaked water, so that the sealing member 100 can be welded to the pipeline in a waterless environment, which is beneficial to ensure the welding effect of the sealing member 100.
[0030] See also Figures 2 to 4Further, the first sleeve 330 is provided with a stepped hole 331, the mounting rod 200 is adapted to the small end of the stepped hole 331, the stepped hole 331 has a stepped surface inside, the large end of the stepped hole 331 faces the elastic member 230, and one end of the elastic member 230 is connected to the stepped surface, so that the elastic member 230 is installed through the stepped hole 331, which is conducive to regulating the deformation direction of the elastic member 230 to avoid the axial deviation of the elastic member 230. It can be understood that the elastic member 230 can select a spring or other plastic or silicone member with elastic deformation ability according to needs, and is not specifically limited.
[0031] See also Figures 2 to 4 Further, the limiting structure includes a plurality of annular protrusions 211 arranged on the outer peripheral wall of the first limiting member 210, the mounting block 310 is connected to the second sleeve 350, the second sleeve 350 is provided with a mounting groove 351, the groove wall of the mounting groove 351 is inclinedly provided with a plurality of elastic sheets 352, and the elastic sheets 352 can be snapped between two adjacent annular protrusions 211. Specifically, the elastic sheets 352 and the corresponding annular protrusions 211 form a group of snap-fit structures, which is conducive to the installation or removal of the mounting block 310 on the first limiting member 210. Among them, the greater the depth of the first limiting member 210 built into the mounting groove 351, the more groups of the elastic sheets 352 and the annular protrusions 211 are matched, which is conducive to improving the firmness of the connection between the mounting block 310 and the first limiting member 210. It is understandable that the movable end of the inclined piece is away from the first stopper 210, and the inclined piece and the axis of the mounting rod 200 form an acute angle, so that the elastic piece 352 can conform to the installation direction of people to reduce the resistance of the installation of the elastic piece 352. In some embodiments, the first stopper 210 and the second sleeve 350 can be threaded or magnetically matched, which will not be described in detail here.
[0032] See also Figure 2 and Figure 3 Furthermore, the elastic bag 400 includes a tightening ring 410, which is connected to an elastically deformable blocking film 420. A hook portion 321 is provided at one end of the first connecting rod 320, and the hook portion 321 defines an installation area that can accommodate the tightening ring 410. Specifically, the tightening ring 410 is an elastic ring or elastic ring that can shrink or expand, and the blocking film 420 can be made of highly elastic plastic, so that the blocking film 420 can gradually expand under the impact of water to form a temporary storage cavity, which is conducive to storing more water leaking from the pipeline, so that the blocking piece 100 can be better welded in a waterless environment. In order to prevent the tightening ring 410 from detaching, after the tightening ring 410 is built into the installation area, the hook portion 321 can continue to bend to form a closed installation area.
[0033] Furthermore, the blocking film 420 includes a plurality of folded edges connected in sequence, and two adjacent folded edges can be folded or unfolded relative to each other, which is beneficial to improving the deformation ability of the blocking film 420, so that the blocking film 420 can form a larger temporary storage cavity that can accommodate leaked water.
[0034] Furthermore, one of the first sleeve 330 and the mounting rod 200 is provided with a sliding groove, and the other is provided with a convex strip matching the sliding groove, and the convex strip is extended in a direction parallel to the axis of the mounting rod 200, so that the first sleeve 330 is guided and limited by the cooperation of the sliding groove and the convex strip, thereby preventing the first sleeve 330 from rotating and affecting the use of the elastic member 230.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
