[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] Combination Figure 1 As shown, the embodiment of the utility model provides an offshore platform pipeline plugging device, including a clamp 1, a pressure rod 4, and a rotating pin 3. The clamp 1 is provided with a rotating mounting seat 2. The clamp 1 can be selected but not limited to metal materials, such as carbon steel or stainless steel materials, etc. The rotating mounting seat 2 and the clamp 1 are preferably made by an integrated molding process to improve the firmness of the combination of the two. It should be noted that when the clamp 1 is composed of two semicircular rings, the rotating mounting seat 2 and one of the semicircular rings of the clamp 1 are preferably made by an integrated molding process. The rotating mounting seat 2 can be selected but not limited to being vertically arranged on the clamp 1, and can also be arranged parallel to the clamp 1. When the rotating mounting seat 2 is vertically arranged on the clamp 1, the rotating groove on the rotating mounting seat 2 opens upward, which is convenient for the pressure rod 4 to adjust the plugging angle according to the rotation of the rotating pin 3. The rotating mounting seat 2 is provided with a rotating groove, and the two side surfaces of the rotating groove are provided with a first rotating pin hole and a second rotating pin hole. The two ends of the rotating pin 3 can be respectively clamped in the first rotating pin hole and the second rotating pin hole and can rotate in the rotating groove. The middle part of the rotating pin 3 is provided with an adjusting hole, and the pressure rod 4 can be telescopic in the adjusting hole and rotate with the rotating pin 3. Specifically, the pressure rod 4 is provided with an external thread, and the adjusting hole is provided with an internal thread that can match the external thread on the pressure rod 4. The screw connection position of the pressure rod 4 in the adjusting hole is adjusted to change the telescopic position of the pressure rod 4; another preferred embodiment includes a driving cylinder and a driving source. The driving cylinder and the driving source can be selected from but not limited to hydraulic cylinders and oil sources, and electric cylinders and electric sources can also be used. The telescopic end of the driving cylinder is connected to the pressure rod 4, and the driving cylinder is driven by the driving source to telescope and drive the pressure rod 4 to telescope in the adjusting hole.

[0021] Combination Figure 2As shown, when the utility model is in use, the clamp 1 is fixed on the pipe 10 to be plugged, and a plugging patch made of the same material as the pipe 10 to be plugged is placed on the end of the pressure rod 4. The rotating pin 3 is rotated to adjust the angle of the position of the pressure rod 4 so that the plugging patch at the end of the pressure rod 4 is aligned with the position to be plugged. According to the material of the position to be plugged, the plugging patch is sealed and fixedly connected to the position to be plugged, such as welding or bonding, to achieve plugging. After the treatment is completed, the plugging tool can be recovered and reused. It should be noted that a sealing gasket can be optionally set between the plugging patch and the position to be plugged according to the on-site plugging operation to ensure the sealing of the plugging process.

[0022] As a further preferred embodiment, it includes at least one clamp reducing rod 6 and at least one reducing hole radially arranged on the side of the clamp 1, and the clamp reducing rod 6 can be telescopically inserted into the reducing hole. Preferably, four clamp reducing rods 6 and four reducing holes evenly distributed on the clamp 1 are used. Further preferably, the clamp reducing rod 6 is provided with an external thread, and the reducing hole is provided with an internal thread that can match the external thread on the clamp reducing rod 6. The fixing condition of the clamp 1 and the pipe 10 to be plugged can be changed by adjusting the threaded position of the clamp reducing rod 6 in the reducing hole, breaking the limitation that the plugging tool is only suitable for a single diameter pipeline, solving the problem of difficulty in fixing when using the plugging tool on irregular pipelines such as reducing pipelines and reducing flanges, improving the versatility of the utility model in plugging operations on offshore platforms, and reducing production costs.

The screwing position of the rotating fixing bolt 7 and the rotating fixing hole is adjusted to fix the rotation angle of the rotating pin 3. When the end of the pressure rod 4 is aligned with the position where the pipeline needs to be plugged, the rotation angle of the rotating pin 3 is fixed by adjusting the rotating fixing bolt 7 at the screwing position of the rotating fixing hole to avoid the pressure rod 4 from moving again when the end is aligned with the position where the plugging needs to be done.

[0024] As a further preferred embodiment, one end of the pressure rod 4 is detachably connected to a leak-proof pressure block 5. When plugging a leak, the leak-proof pressure block 5 is directly used as a leak-proof patch; or a material of the same material as the pipe 10 to be plugged is used as a leak-proof patch. The leak-proof pressure block 5 is used to increase the pressure contact area between the leak-proof patch and the position to be plugged on the pipe. The leak-proof pressure block 5 is used to pressurize the space between the leak-proof patch and the pipe 10 to be plugged through the pressure rod 4 to ensure the sealing effect of the leak plugging.
