For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the leakage plugging device for a marine pipe according to an embodiment of the present invention is used for wrapping and clamping a leakage point of a marine pipe to seal the leakage point. The sea pipe leakage stopping equipment comprises a sea pipe leakage stopping pipe clamp 10 and a clamping device arranged on the sea pipe leakage stopping pipe clamp 10. The sea pipe leakage plugging pipe clamp 10 is used for wrapping leakage points of the sea pipe; the clamping device comprises two groups of clamping units 20 and at least one driving mechanism 23, wherein the two groups of clamping units 20 are respectively installed at two opposite ends of the sea pipe leakage stopping pipe clamp 10 and are used for clamping the sea pipe leakage stopping pipe clamp 10 on the sea pipe, and the sea pipe leakage stopping pipe clamp 10 is clamped and fixed on the sea pipe.
The sea pipe plugging pipe clamp 10 is a tubular structure with a certain axial length, and the length of the sea pipe plugging pipe clamp is set on the basis of being larger than the length of a leakage point on a sea pipe so as to sufficiently wrap the leakage point. Generally, to facilitate the disassembly and assembly, the sea pipe plugging pipe clamp 10 comprises two semicircular clamping flaps 11 which are oppositely matched. When the device is installed, the two clamping flaps 11 are matched on the marine vessel from two sides of the marine vessel, and after the two clamping flaps 11 are matched and butted oppositely, the two clamping flaps 11 are locked into a whole through the locking device, so that the marine vessel plugging pipe clamp 10 wrapped on the marine vessel is formed.
Each group of clamping units 20 comprises a clamping tube 21 and a piston 22; the clamping tube 21 is fitted in the end part of the sea pipe plugging tube clamp 10, the piston 22 is fitted in the end part of the sea pipe plugging tube clamp 10, one end of the piston extends to a position between the clamping tube 21 and the inner wall of the end part, and the driving mechanism 23 is connected with the piston 22 and drives the piston 22 to axially move relative to the sea pipe plugging tube clamp 10. One end of the piston 22 extending between the clamping tube 21 and the inner wall of the end portion and the outer peripheral surface of the clamping tube 21 are provided with wedge structures 30 which are matched with each other, when the driving mechanism drives the piston 22 to move axially, the piston 22 extrudes the clamping tube 21 through the wedge structures 30, and the clamping tube 21 is driven to move radially and clamped on the marine pipe.
As shown in fig. 3, the wedge structure 30 includes first helical teeth 31 provided on an inner circumferential surface of one end of the piston 22, and second helical teeth 32 provided on an outer circumferential surface of the grip tube 21 and engaged with the first helical teeth 31. When the piston 22 moves axially in the direction of arrow a in fig. 3, the clamping tube 21 is driven by the wedge structure 30 to move radially in the direction of arrow B, so that the clamping tube 21 can be clamped on the sea pipe.
the clamping tube 21 is directly wrapped on the outer peripheral surface of the sea pipe inside the sea pipe leaking stoppage pipe clamp 10, and in order to keep the inner peripheral surface of the sea pipe leaking stoppage pipe clamp 10 to be in contact with the outer peripheral surface of the sea pipe, a positioning groove (not shown) is arranged in the end part of the sea pipe leaking stoppage pipe clamp 10 for accommodating the clamping tube 21, so that the inner peripheral surface of the clamping tube 21 is approximately flush with the inner peripheral surface of the sea pipe leaking stoppage pipe clamp 10 in the end part of the sea pipe leaking stoppage pipe clamp 10.
The inner wall of the clamping pipe 21 is provided with clamping teeth 210 which can be clamped on the marine pipe, so that the friction force between the clamping pipe 21 and the marine pipe is increased, and the clamping is firmer and more reliable. The holding teeth 210 may be one or more spaced apart and arranged along the circumference of the holding tube 21.
In order to make the clamping tube 21 move radially to generate a compression deformation to clamp on the sea pipe, the clamping tube 21 is provided with a plurality of cutting grooves 211 which are distributed at intervals and extend along the axial direction of the clamping tube 21; the openings of two adjacent slots 211 are located on opposite ends of the clamp tube 21, respectively. The slots 211 are arranged such that the grip pipe 21 is formed with a plurality of compression spaces in a circumferential direction, and when the piston 22 drives the grip pipe 21 to move radially, the slots 211 are compressed to be gradually closed, so that the inner diameter of the grip pipe 21 is also reduced to be clamped on the sea pipe.
The piston 22 further may include a piston ring 221 fitted on the end of the sea pipe lost circulation pipe clamp 10, and a piston cylinder 222 connected to one side of the piston ring 221. The piston cylinder 222 extends between the holding pipe 21 and the inner wall of the end of the sea pipe lost circulation pipe clamp 10.
When the sea pipe is not clamped, a certain distance is reserved between the end part of the sea pipe plugging pipe clamp 10 and the end surface of the end part of the sea pipe plugging pipe clamp by the piston ring 221 to serve as a clamping driving stroke. When the driving mechanism 23 drives the piston 22 to move axially to the end face of the end of the sea pipe plugging pipe clamp 10, that is, the piston 22 moves to the bottom end of the clamping driving stroke, it indicates that the clamping driving of the clamping pipe 21 is completed, and the clamping pipe 21 completes the clamping action on the sea pipe.
The holding tube 21 and the piston 22 are made of metal.
The drive mechanism 23 may be implemented in the form of a hydraulic drive. Alternatively, the driving mechanism 23 may include a screw 231 having one end penetrating into the piston 22 and the sea pipe plugging pipe clamp 10, a nut 232 fitted on the screw 231 at a side of the piston 22 away from the end of the sea pipe plugging pipe clamp 10, and a hydraulic cylinder 233 fitted on the screw 231 and driving the nut 232 to rotate. The hydraulic cylinder 233 is actuated to drive the nut 232 to rotate and the screw 231 to move axially, so as to drive the piston 22 to move axially relative to the sea pipe plugging pipe clamp 10.
In this embodiment, the clamping tube 21 includes two clamping sections respectively fitted in the end portions of the two clamping sections corresponding to the two clamping sections 11 of the sea pipe leaking stoppage pipe clamp 10. When the two clamping flaps 11 are butted, the two clamping sections are also butted to form an integral clamping tube 21.
Similarly, the piston 22 includes two oppositely fitting piston lobes, each having half of the piston ring 221 and half of the piston cylinder 222, with one end of the piston lobe (i.e., half of the piston cylinder 222) extending between the clamping section and the inner wall of the end of the snap lobe 11. To balance the movement of the drive piston 22, at least one drive mechanism 23 is connected to each piston lobe.
The butt joint surfaces of the two clamping sections can be provided with concave-convex structures matched with each other for butt joint of the two clamping sections. The butt joint surfaces of the two piston valves can also be respectively provided with concave-convex structures which are matched with each other and used for butt joint of the two piston valves.
Further, in the present embodiment, as shown in fig. 1, the driving mechanism 23 is disposed at one end of the sea pipe plugging pipe clamp 10; two drive mechanisms 23 are connected to each piston lobe of the piston 22 at this end. The other end of the sea pipe plugging pipe clamp 10 is not provided with the driving mechanism 23, so that the driving mechanism 23 can drive the pistons 22 of the two groups of clamping units 20 to move axially at the same time.
Specifically, the screw 231 of the driving mechanism 23 penetrates into the piston 22 on one end of the sea pipe plugging pipe clamp 10 and enters into the sea pipe plugging pipe clamp 10, and another piston 22 is connected along the sea pipe plugging pipe clamp 10 to the opposite other end; nut 232 is located between piston 22 and cylinder 233. After the hydraulic cylinder 233 is started, the nut 232 is driven to rotate and move axially along the screw 231, so as to drive the two pistons 22 at the two ends of the sea pipe plugging pipe clamp 10 to move oppositely, so that the clamping units 20 at the two ends of the sea pipe plugging pipe clamp 10 act simultaneously, and further drive the clamping pipe 21 to move radially and clamp on the sea pipe.
It should be understood that in other embodiments, the driving mechanisms 23 may also be disposed at two end portions of the sea pipe plugging pipe clamp 10, and respectively drive the clamping units 20 at the two end portions to clamp the sea pipe.
Further, in the present invention, the holding device further comprises an ROV operating panel 40 disposed on the sea pipe plugging pipe clamp 10. The ROV operation panel 40 is provided with a hydraulic port 41 for connecting to the drive mechanism 23, a pressure gauge 42 for detecting a hydraulic oil pressure, and a hydraulic passage valve 43 for controlling the opening and closing of the hydraulic port 41.
When the device is installed on a marine pipe, firstly, two clamping flaps 11 of a marine pipe leakage stopping pipe clamp 10 are oppositely matched and wrapped outside a leakage point of the marine pipe to be maintained, and then the two clamping flaps 11 are locked together by using a locking device. Then, a hydraulic quick coupling (hot stab) is inserted into the hydraulic interface 41 of the ROV operation panel 40 by the ROV or an operator, the hydraulic cylinder 233 is driven to operate through a hydraulic pipeline, the hydraulic cylinder 233 drives the nut 232 to axially rotate along the screw 231 to the extrusion piston 22, and the extrusion piston 22 is driven to simultaneously axially move along the screw 232. When the piston 22 moves axially, the piston 22 presses the second helical teeth 32 on the clamping tube 21 through the first helical teeth 31, so that the clamping tube 21 is pressed to move radially, and the clamping teeth 210 of the clamping tube 21 are meshed on the surface of the sea pipe, thereby realizing the pipe clamp clamping function.
When the piston 22 moves to the bottom end of the clamping driving stroke, the reading of the pressure gauge 42 can be observed to rise and keep unchanged, the clamping driving is finished, the hydraulic passage valve 43 is closed, the clamping action is finished, and the clamping and the installation of the sea pipe plugging pipe clamp 10 are finished.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
