[0001] The utility model relates to the technical field of cable installation, and specifically, to a cable installation sealing device. Background Art

[0002] Cables are a general term for items such as optical cables and electric cables. Some cables need to be installed inside pipelines. The new type of cable adopts an inflatable flexible cable pipeline sealing technology inside the pipeline, mainly using the inflation and expansion of an airbag for sealing, which has the advantages of convenient and fast installation and long-lasting sealing performance. Although the existing cables use the inflation and expansion of an airbag for sealing during installation, when sealing, the airbag needs to be inflated, and when the cable is overhauled, the airbag needs to be deflated again. Since the inflation and deflation processes are relatively slow and waiting is required, time is wasted. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0028] Embodiment 1

[0029] As Figures 1-3 shown, this embodiment proposes a cable installation sealing device, including:

[0030] A sealing component, the sealing component includes the second support plate 13;

[0031] A movable component, the movable component includes the first through hole 21, the movable column 22, the clamping plate 23, the first telescopic spring 24, the support column 25 and the fixing nut 26;

[0032] The first through hole 21 is opened at the peripheral position of the outer end of the second support plate 13. The movable column 22 penetrates through the first through hole 21 and extends inward. The clamping plate 23 is fixedly connected to the inner end face of the movable column 22. The first telescopic spring 24 is fixedly connected to the top position of the movable column 22. The support column 25 is placed inside the first through hole 21. The fixing nut 26 is threadedly connected to the outer surface of the upper end of the support column 25;

[0033] The first through hole 21 is used to place the support column 25. The movable column 22 is used to support the clamping plate 23. The clamping plate 23 is used to contact the outer surface of the cable. The first telescopic spring 24 is used to generate an elastic force to drive the movable column 22 to move inward. The support column 25 is used to support the movable column 22. The fixing nut 26 is used to limit the position of the support column 25;

[0034] The sealing assembly further includes a first support plate 11 and a sealing airbag 12;

[0035] The sealing airbag 12 is fixedly connected to the outer side of the first support plate 11. The second support plate 13 is located on the outer side of the sealing airbag 12, and the first support plate 11 and the second support plate 13 are of T-shaped structures;

[0036] The first support plate 11 and the second support plate 13 are respectively used to apply pressure to both sides of the sealing airbag 12, and the sealing airbag 12 is used to seal the outer surface of the cable;

[0037] The outer end of the movable column 22 and the first telescopic spring 24 are located inside the support column 25, and the movable column 22 is of a T-shaped structure;

[0038] When the support column 25 moves inward, it can drive the movable column 22 and the first telescopic spring 24 to move;

[0039] The clamping plate 23 is of an arc-shaped structure and is located inside the second support plate 13;

[0040] When the clamping plate 23 contacts the outer surface of the cable, continue to move the support column 25, and the support column 25 drives the first telescopic spring 24 to be compressed;

[0041] There is a threaded structure on the outer surface of the support column 25 corresponding to the fixed nut 26, and the first telescopic spring 24 contacts the inner top end of the support column 25;

[0042] By means of the fixed nut 26, the support column 25 can be fixed at the outer end of the second support plate 13;

[0043] Working principle: When it is necessary to use the sealing airbag 12 to seal the cable, place the first support plate 11 on the outer surface of the cable and move the support column 25 inward. The support column 25 drives the first telescopic spring 24 and the movable column 22 to move inward. The inward movement of the movable column 22 drives the clamping plate 23 to move inward. When the clamping plate 23 contacts the outer surface of the cable, continue to move the support column 25. The first telescopic spring 24 is compressed by the support column 25 to generate an elastic force, thereby applying an outward force to the movable column 22 and the clamping plate 23 to fix the cable. At this time, move the second support plate 13 inward to make the first support plate 11 and the second support plate 13 squeeze the sealing airbag 12, so that the sealing airbag 12 seals the outer surface of the cable. Repeating the above steps can fix the second support plate 13.

[0044] Embodiment 2

[0045] As Figure 4 shown, based on the same concept as the above Embodiment 1, it further includes:

[0046] Detection component, the detection component includes a second through hole 31, a hollow circular groove 32, a connecting rod 33, a stop block 34, a limiting block 35, a second telescopic spring 36 and a pressure sensor 37;

[0047] The second through hole 31 is opened at the peripheral position of the outer surface of the second support plate 13, the hollow circular groove 32 is opened at the outer side position of the second through hole 31, the connecting rod 33 penetrates through the second through hole 31 and extends to both sides, the stop block 34 is fixedly connected to one end position of the connecting rod 33, the limiting block 35 is fixedly connected to the other end position of the stop block 34, one end of the second telescopic spring 36 is fixedly connected to the inner side surface of the limiting block 35, and the pressure sensor 37 is placed inside the hollow circular groove 32;

[0048] The second through hole 31 is used to place the connecting rod 33, the hollow circular groove 32 is used to place the pressure sensor 37, the connecting rod 33 is used to support the stop block 34 and the limiting block 35, the stop block 34 is used to contact the outer side of the sealing airbag 12, the limiting block 35 is used to support the second telescopic spring 36, the second telescopic spring 36 is stretched to generate elastic force, and the pressure sensor 37 is used to measure the elastic force of the second telescopic spring 36;

[0049] The stop block 34 is located at the inner side position of the second support plate 13, and the limiting block 35 is located at the outer end position of the second support plate 13;

[0050] The stop block 34 and the limiting block 35 always maintain a relative distance. When the stop block 34 moves outward, the limiting block 35 is driven to move outward through the connecting rod 33;

[0051] The second telescopic spring 36 is wound around the outer surface of the connecting rod 33, and the other end of the second telescopic spring 36 is fixedly connected to the outer surface of the pressure sensor 37;

[0052] When the limiting block 35 moves outward, the second telescopic spring 36 moves outward under the drive of the limiting block 35;

[0053] Working principle: When using the sealing airbag 12 to seal the cable, the sealing airbag 12 generates an outward thrust on the stop block 34. The stop block 34 drives the connecting rod 33 and the limiting block 35 to move outward. The outward movement of the limiting block 35 drives the second telescopic spring 36 to be stretched outward. At this time, the pressure sensor 37 measures the second telescopic spring 36. When the sealing airbag 12 leaks air, under the elastic force of the second telescopic spring 36, the limiting block 35 moves inward and drives the stop block 34 to move inward. When the stop block 34 and the limiting block 35 move inward, the stretching state of the second telescopic spring 36 decreases, and the tension of the second telescopic spring 36 measured by the pressure sensor 37 decreases, thereby judging the inflation state of the sealing airbag 12.

[0054] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
