[0042] Embodiment

[0043] See Figure 1 , this embodiment provides a rush repair tool for a pressure pipeline 6, which includes an arc-shaped block 1, a flexible leak-proof bag 2, a first clamping plate 3, a connection mechanism, and an inflation mechanism 5.

[0044] The arc-shaped block 1 can cover the pressure pipeline 6. The arc-shaped block 1 is made of stainless steel.

[0045] The flexible leak-proof bag 2 is arranged inside the arc-shaped block 1. The flexible leak-proof bag 2 is made of a flexible material, and the inside of the flexible leak-proof bag 2 has a cavity. 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).

[0046] The first clamping plate 3 and the arc-shaped block 1 can be respectively arranged on the opposite sides of the pressure pipeline 6. The first clamping plate 3 is detachably connected to the arc-shaped block 1 through the connection mechanism and the distance between the first clamping plate 3 and the arc-shaped block 1 is adjustable; when the distance between the first clamping plate 3 and the arc-shaped block 1 is reduced, the first clamping plate 3 and the arc-shaped block 1 cooperate to clamp and fix the rush repair tool of the pressure pipeline 6 at the leakage point of the pressure pipeline 6.

[0047] The connection mechanism includes an elastic member, and the restoring force of the elastic member is used to move the first clamping plate 3 towards the pressure pipeline 6. Specifically, the elastic member includes a spring 41.

[0048] The inflation mechanism 5 is connected to the air inlet nozzle 21; when the distance between the first clamping plate 3 and the arc-shaped block 1 is reduced, the spring 41 is compressed, and the inflation mechanism 5 inflates the cavity.

[0049] When using the emergency repair tool for the pressure pipeline 6, place the arc-shaped block 1 on the pressure pipeline 6, make the flexible leak-proof bag 2 cover the leakage part of the pressure pipeline 6, and then connect the first clamping plate 3 and the arc-shaped block 1 through the connecting mechanism and reduce the distance between the first clamping plate 3 and the arc-shaped block 1. Clamp and fix the repair tool of the pressure pipeline 6 on the pressure pipeline 6 through the cooperation of the first clamping plate 3 and the arc-shaped block 1. The inflation mechanism 5 is associated with the first clamping plate 3 and the connecting mechanism; during the process of reducing the distance between the first clamping plate 3 and the arc-shaped block 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 first clamping plate 3 and the arc-shaped block 1 to ensure the sealing performance. On the other hand, the inflated flexible leak-proof bag 2 can adapt to the uneven outer wall of the pressure pipeline 6, making the flexible leak-proof bag 2 closely fit the outer wall of the pressure pipeline 6, further ensuring the sealing performance.

[0050] The connecting mechanism includes an extension rod 42, a second clamping plate 43, a limiting member, and a connecting rod 45.

[0051] Two extension rods 42 are arranged on the arc-shaped block 1.

[0052] The second clamping plate 43 is slidably connected to the extension rod 42.

[0053] The limiting member and the first clamping plate 3 are located on opposite sides of the second clamping plate 43. The limiting member is used to adjust the distance between the first clamping plate 3 and the arc-shaped block 1. Specifically, the limiting member includes a limiting nut 44, and the limiting nut 44 is threadedly connected to the extension rod 42. Turning the limiting nut 44 can adjust the distance between the first clamping plate 3 and the arc-shaped block 1.

[0054] The first clamping plate 3 is slidably connected to the second clamping plate 43 through the connecting rod 45; one end of the spring 41 is connected to the first clamping plate 3, and the other end is connected to the second clamping plate 43. The spring 41 is sleeved on the connecting rod 45.

[0055] When using the connecting mechanism, first connect the extension rod 42 to the second clamping plate 43, and then use the limiting member to adjust the distance between the first clamping plate 3 and the arc-shaped block 1. The installation is convenient.

[0056] The inflation mechanism 5 includes an inflation container 51 and a movable plug 52.

[0057] The inflation container 51 is arranged on the second clamping plate 43. The inflation container 51 has an air inlet 53 and an air outlet, and the air outlet is connected to the air inlet nozzle 21 through a conduit.

[0058] The movable plug 52 is slidably and sealingly fitted with the inner wall of the inflation container 51, and one end of the connecting rod 45 is connected to the movable plug 52.

[0059] During the process of reducing the distance between the first clamping plate 3 and the arc-shaped block 1, the first clamping plate 3 moves towards the second clamping plate 43, the spring 41 is compressed, and the air in the inflatable container 51 is pushed into the cavity through the movable plug 52, thus conveniently achieving the purpose of expanding the flexible leak-proof bag 2.

[0060] It should be noted that in this embodiment, by associating the inflating mechanism 5 with the first clamping plate 3 and the connecting mechanism, the purpose of expanding the flexible leak-proof bag 2 is conveniently achieved; in other embodiments, the inflating mechanism 5 can also work independently, and the user can manually control the timing of inflation.

[0061] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Without conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
