[0022] Please refer to Figure 1 It is a kind of mechanical pipe clamp device of submarine pipeline installed by using unmanned remote submersible in some embodiments of the utility model, which comprises first pressurizing plate 11, second pressurizing plate 12, multiple compression members 13, outer pressure plate 14, first sealing member 15, second sealing member 16, butt joint member 17, connecting member 18, positioning assembly 19 and handpiece 20. Second pressurizing plate 12 is hingedly connected with outer pressure plate 14, first pressurizing plate 11 is movably connected with outer pressure plate 14 and located on the inner side of outer pressure plate 14, first sealing member 15 is installed on the inner wall surface of first pressurizing plate 11, second sealing member 16 is installed on the inner wall surface of second pressurizing plate 12, first sealing member 15 and second sealing member 16 are used for plugging submarine pipeline together, multiple compression members 13 are installed on outer pressure plate 14 and used for applying pressure to first pressurizing plate 11. Positioning assembly 19 is connected to second pressurizing plate 12, butt joint member 17 is connected to positioning assembly 19, connecting member 18 is drivingly connected with butt joint member 17, and handpiece 20 is fixedly connected with connecting member 18. Among them, compression member 13 is compression bolt, compression member 13 is threadedly connected with outer pressure plate 14, and outer pressure plate 14 and second pressurizing plate 12 are hingedly connected through rotating shaft 23. And handpiece 20 can be operated by unmanned remote submersible to complete the installation of mechanical pipe clamp device of submarine pipeline, and handpiece 20 and connecting member 18 can be welded.

[0023] Understandably, the submarine pipeline mechanical pipe clamp device can block the leakage point on the submarine pipeline to achieve sealing by setting the first pressing plate 11 and the second pressing plate 12 and by the first sealing element 15 and the second sealing element 16 used together to block the submarine pipeline. By setting the outer pressing plate 14 and the pressing element 13, the force on the leakage point can be adjusted, the local pressure at the leakage point position is increased, and the stability of the pipeline sealing is enhanced. At the same time, since the handpiece 20 is provided, single unmanned remote control submersible can be operated, the unmanned remote control submersible can operate the handpiece 20 to preliminarily lock the relative position between the outer pressing plate 14 and the second pressing plate 12, and the unmanned remote control submersible can also operate the pressing element 13 to make the first sealing element 15 and the second sealing element 16 more closely adhere to the pipe wall of the submarine pipeline, thereby improving the blocking effect. The submarine pipeline mechanical pipe clamp device does not need 360-degree sealing, but only covers and seals the leakage position of the submarine pipeline, which is convenient for on-site construction.

[0024] The submarine pipeline mechanical pipe clamp device further comprises a limiting element 24 and a guide element 25. The limiting element 24 is provided through the outer pressing plate 14 and is connected to the outer wall surface of the first pressing plate 11. The guide element 25 is fixed on the outer pressing plate 14 and abuts against the side wall surface of the first pressing plate 11. Specifically, the outer pressing plate 14 is provided with a through hole for the limiting element 24 to pass through. The top of the limiting element 24 is larger than the through hole in size. The bottom of the limiting element 24 is fixedly connected to the outer wall surface of the first pressing plate 11. The guide element 25 is installed on both sides of the outer pressing plate 14. The guide element 25 is used to guide the movement of the first pressing plate 11, so that the first pressing plate 11 can only move in the height direction. The limiting element 24 is used to limit the movement distance of the first pressing plate 11. When the outer pressing plate 14 and the second pressing plate 12 are folded, the pressing element 13 can be tightened. At this time, the first pressing plate 11 is pressed towards the submarine pipeline to make the first pressing plate 11 and the second pressing plate 12 clamp the submarine pipeline together.

[0025] In addition, the outer pressing plate 14, the first pressing plate 11 and the second pressing plate 12 are all arc-shaped structures. The arc-shaped structure matches the shape of the submarine pipeline. The length of the outer pressing plate 14, the first pressing plate 11 and the second pressing plate 12 can be increased or decreased, and the pressing force of the pressing element 13 can be adjusted, that is, the arc-shaped structure is pressed and covered by the point pressing design of the pressing element 13, to realize the local sealing of the leakage point of the submarine pipeline.

[0026] The first sealing element 15 and the second sealing element 16 are both rubber elements. The first sealing element 15 is pasted on the inner wall surface of the first pressing plate 11, and the second sealing element 16 is pasted on the inner wall surface of the second pressing plate 12. The rubber element can prevent the leakage of liquid and gas, and has excellent shock absorption performance and wear resistance and corrosion resistance.

[0027] The subsea pipeline mechanical pipe clamp device further comprises a lifting lug 26 arranged on the outer pressing plate 14, and the overall transportation of the subsea pipeline mechanical pipe clamp device can be facilitated by installing the lifting lug 26.

[0028] The positioning assembly 19 comprises a retaining plate 191 connected with the second pressing plate 12 and a positioning shaft 192 connected with the retaining plate 191, and the abutting piece 17 is fixedly connected with the positioning shaft 192. The subsea pipeline mechanical pipe clamp device further comprises a clamping piece 21 connected with the outer pressing plate 14, and the clamping piece 21 is provided with a clamping groove 211 for the abutting piece 17 to pass through. The abutting piece 17 is an abutting bolt, and the connecting piece 18 is a connecting nut corresponding to the abutting bolt. Specifically, the retaining plate 191 and the second pressing plate 12 can be weldedly connected, the abutting piece 17 can be weldedly connected with the positioning shaft 192, and the abutting piece 17 is located at the middle position of the positioning shaft 192. When it is necessary to fold the outer pressing plate 14, the connecting piece 18 can be screwed by using the unmanned remotely controlled submersible, so that the connecting piece 18 abuts on the clamping piece 21 to lock the relative position between the outer pressing plate 14 and the second pressing plate 12.

[0029] The wall thicknesses of the first pressing plate 11 and the second pressing plate 12 are both 8 mm to 12 mm, the wall thickness of the outer pressing plate 14 is 15 mm to 18 mm, and the widths of the first pressing plate 11, the second pressing plate 12 and the outer pressing plate 14 are all 180 mm to 220 mm. Preferably, the wall thicknesses of the first pressing plate 11 and the second pressing plate 12 are both 10 mm, the wall thickness of the outer pressing plate 14 is 16.8 mm, and the widths of the first pressing plate 11, the second pressing plate 12 and the outer pressing plate 14 are all 200 mm. Understandably, by optimizing the wall thicknesses of the first pressing plate 11, the second pressing plate 12 and the outer pressing plate 14, the first pressing plate 11, the second pressing plate 12 and the outer pressing plate 14 have sufficient pressing and sealing capabilities and also have certain deformation capabilities, the deformation can be changed by adjusting the torque of the pressing piece 13, the first sealing piece 15 and the second sealing piece 16 inside the pipe clamp can be more closely attached to the pipe wall, and the plugging effect is improved. At the same time, the widths of the first pressing plate 11, the second pressing plate 12 and the outer pressing plate 14 are set, which can be installed in a space with a small position.

[0030] In general, since there are usually only 1-2 defect or perforation locations on the submarine pipeline, it is enough to successfully seal the defect or perforation location. Therefore, the submarine pipeline mechanical pipe clamp device adopts the design of point pressure of the pressing member 13 and the pressure cover of the pressing plate, and the submarine pipeline mechanical pipe clamp device does not need to be sealed for 360 degrees. The sealing position is a circular arc plate, and only the leakage point is sealed and plugged. By increasing or decreasing the length of the pressing plate and adjusting the torque of the pressing member 13, local sealing of the leakage point can be achieved, and it can be applied to leakage plugging of submarine pipelines with large ovality deviation. The point pressure of the pressing member 13 can target the defect and perforation location, and the sealing area of the point pressure is small, which can increase the pressure of the sealing position and improve the sealing effect of the sealing position. Moreover, since it is not installed by divers, the mechanical arm of the unmanned remote control submersible can only perform relatively simple operations and cannot accurately aim the pressing member 13 at the defect or perforation location. Therefore, in the design of the pressure cover of the pressing member 13, the force applied by the pressing member 13 to the pressing plate, the first sealing member 15 and the second sealing member 16 are pressed on the defect or perforation location on the submarine pipeline, and the submarine pipeline is plugged.

[0031] The steps of installing the submarine pipeline mechanical pipe clamp device by the unmanned remote control submersible are as follows:

[0032] 1. The engineering ship arranges the construction site for construction preparation;

[0033] 2. The unmanned remote control submersible confirms the location of the leakage point;

[0034] 3. The unmanned remote control submersible performs interference analysis;

[0036] 5. The unmanned remote control submersible brings the submarine pipeline mechanical pipe clamp device to the leakage location of the submarine pipeline;

[0037] 6. The outer pressing plate 14 and the first pressing plate 11 are placed above the leakage location of the submarine pipeline;

[0038] 7. The unmanned remote control submersible preliminarily locks the outer pressing plate 14 and the second pressing plate 12 by using the handpiece member 20;

[0039] 8. The location of the leakage point is determined, and the location is determined;

[0040] 9. The outer pressing plate 14 and the second pressing plate 12 are completely locked, and the torque of the pressing member 13 is adjusted;
