[0045] Embodiment

[0046] See Figure 1 , this embodiment provides a leak plugging device, including a rectangular structure 1, a flexible leak plugging bag 2, a first clamping plate 3, an elastic member, and an inflation mechanism 5.

[0047] The diagonal length of the rectangular structure 1 is variable, and at least one side of the rectangular structure 1 is detachable. The rectangular structure 1 can be clamped and fixed on pressure pipes 7 with various diameters.

[0048] The flexible leak plugging bag 2 is arranged on one inner side of the rectangular structure 1. The flexible leak plugging bag 2 is made of a flexible material, and the inside of the flexible leak plugging bag 2 has a cavity, and the cavity is connected with an air inlet nozzle 21. After the cavity is inflated through the air inlet nozzle 21, the volume of the cavity can be changed (increased).

[0049] The first clamping plate 3 is arranged on one inner side of the rectangular structure 1, and the first clamping plate 3 and the flexible leak plugging bag 2 are located on the opposite side or adjacent sides of the rectangular structure 1.

[0050] The elastic member is installed on the rectangular structure 1, and the restoring force of the elastic member is used to move the first clamping plate 3 towards the pressure pipeline 7. Specifically, the elastic member includes a spring 41.

[0051] The inflation mechanism 5 is connected to the air inlet nozzle 21; when the diagonal length of the rectangular structure 1 is reduced, the spring 41 is compressed, and the inflation mechanism 5 inflates the cavity.

[0052] When the leak plugging device is used emergently, first remove one side from the rectangular structure 1, place the remaining part of the rectangular structure 1 on the pressure pipeline 7, so that the flexible leak plugging bag 2 covers the leakage part of the pressure pipeline 7, and then reassemble the rectangular structure 1 and reduce the diagonal length of the rectangular structure 1 to clamp and fix the leak plugging device on the pressure pipeline 7. By setting the diagonal length of the rectangular structure 1 in a variable and adjustable form, it can adapt to pressure pipelines 7 with various diameters. The inflation mechanism 5 is associated with the change of the diagonal length of the rectangular structure 1; during the process of reducing the diagonal length of the rectangular structure 1, the spring 41 is compressed, and the inflation mechanism 5 inflates the cavity. On the one hand, this can further improve the clamping force of the rectangular structure 1 to ensure the sealing performance. On the other hand, the inflated flexible leak plugging bag 2 can adapt to the uneven outer wall of the pressure pipeline 7, making the flexible leak plugging bag 2 closely fit with the outer wall of the pressure pipeline 7, further ensuring the sealing performance.

[0053] The rectangular structure 1 includes a first support plate 11, a fixing plate 12, a second support plate 13 and a second clamping plate 14 that can be sequentially connected.

[0054] A groove is formed on the side of the first support plate 11 facing the pressure pipeline 7, and the flexible leak plugging bag 2 is arranged in the groove.

[0055] One end of the fixing plate 12 is connected to the first support plate 11.

[0056] One end of the second support plate 13 is detachably connected to the other end of the fixing plate 12. The distance between the second support plate 13 and the first support plate 11 is adjustable.

[0057] One end of the second clamping plate 14 is detachably connected to the other end of the second support plate 13, and the other end of the second clamping plate 14 is slidably connected to the first support plate 11. The second clamping plate 14 can slide relative to the second support plate 13, and the distance between the second clamping plate 14 and the fixing plate 12 is adjustable. The first clamping plate 3 is slidably connected to the second clamping plate 14.

[0058] By reducing the distance between the second support plate 13 and the first support plate 11, and the distance between the second clamping plate 14 and the fixing plate 12, the diagonal length of the rectangular structure 1 can be reduced, so that the plugging device can be clamped and fixed on the pressure pipe 7. In the process of reducing the diagonal length of the rectangular structure 1, the first clamping plate 3 moves toward the second clamping plate 14, the spring 41 is compressed, and the inflation mechanism 5 inflates the cavity.

[0059] The second support plate 13 is detachably connected to the fixed plate 12 and the second clamping plate 14 in the following manner: the fixed plate 12 and the second clamping plate 14 are both provided with an extension rod 15; the second support plate 13 is slidably connected to the extension rod 15; a limiting member is provided on the extension rod 15, and the limiting member is used to adjust the distance between the first clamping plate 3 and the first support plate 11. Specifically, the limiting member includes a limiting nut 16, which is threadedly connected to the extension rod 15, and the distance between the first clamping plate 3 and the first support plate 11 can be adjusted by screwing the limiting nut 16.

[0060] The first clamping plate 3 is connected to the second clamping plate 14 in the following manner: the first clamping plate 3 is slidably connected to the second clamping plate 14 via a connecting rod 31 ; one end of a spring 41 is connected to the first clamping plate 3 , and the other end is connected to the second clamping plate 14 , and the spring 41 is sleeved on the connecting rod 31 .

[0061] In order to facilitate the adjustment of the spacing between the second clamping plate 14 and the fixed plate 12, the leak-proofing equipment also includes a driving mechanism for adjusting the spacing between the fixed plate 12 and the second clamping plate 14. The driving mechanism includes a motor 61, a screw 62 and a slider 63 that are transmission-connected. The slider 63 is in sliding contact with the first support plate 11. The slider 63 can slide on the first support plate 11 under the drive of the motor 61. The second clamping plate 14 is connected to the slider 63 through a through rod 64. The through rod 64 penetrates the first support plate 11 to facilitate the connection between the second clamping plate 14 and the slider 63.

[0062] The inflation mechanism 5 includes an inflation container 51 and a movable plug 52 .

[0063] The gas-filled container 51 is disposed on the second clamping plate 14 . The gas-filled container 51 has an air inlet 53 and an air outlet. The air outlet is connected to the air inlet nozzle 21 through a conduit.

[0064] The movable plug 52 is slidably and sealingly matched with the inner wall of the gas-filled container 51 , and one end of the connecting rod 31 is connected to the movable plug 52 .

[0065] In the process of reducing the diagonal length of the rectangular structure 1, the first clamping plate 3 moves toward the second clamping plate 14, the spring 41 is compressed, and the air in the inflatable container 51 is pushed into the cavity through the movable plug 52, thereby conveniently achieving the purpose of expanding the flexible leak-stopping bag 2.

[0066] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
