Description

Technical Field

[0001] This invention relates to the field of pipeline repair technology, and in particular to an underwater pipeline repair mechanism. Background Technology

[0002] Underwater pipelines are widely used in oil and gas transportation, municipal water supply and drainage, water conservancy projects and other fields. During long-term service, they are susceptible to the effects of water flow erosion, marine organism attachment, geological subsidence and corrosion, which can lead to defects such as cracks and perforations. If these defects are not repaired in time, they can cause problems such as media leakage, water pollution and transportation interruption, resulting in huge economic losses and ecological damage.

[0003] Currently, underwater pipeline repair methods mainly rely on manual sealing by divers or simple casing repair. Manual repair by divers is limited by factors such as low underwater visibility, limited operating depth, and human physiological limits, resulting in problems such as low efficiency, high risk, and poor repair accuracy. Simple casing repair can only achieve temporary external sealing and cannot reinforce the damaged area internally. In addition, water can easily remain between the casing and the pipeline, making it difficult for the sealant to adhere tightly, and leakage is likely to occur again after repair. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0017] The beneficial effects of this invention are as follows: the sealing plate of the sealing component, together with the sealing gasket, initially seals the rupture from the inside of the pipe. Then, the clamp is used to pull the cable to squeeze the sealing plate, and the squeezing bolts can position the sealing plate to prevent it from shifting. Subsequently, the top and bottom protective shells of the protective component form external protection for the damaged area. The sealant can also be injected through the injection tube to fill the gap, achieving double sealing and effectively preventing the pipe from leaking again. This invention uses a driving component to move a lifting plate downwards, allowing a penetration needle to pierce the isolation membrane, releasing the sponge from compression and absorbing the water accumulated above the sealing plate. After the water is absorbed, a release component can eject the water-absorbing sponge from the lifting plate, ensuring no water residue remains at the sealing point. This allows the subsequently injected sealant to adhere tightly to the damaged area of ​​the pipe, further improving the repair quality. Attached Figure Description

Detailed Implementation

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1, referring to Figure 1 , Figure 3 , Figure 4 and Figures 6-8This is the first embodiment of the present invention. This embodiment provides an underwater pipeline repair mechanism. The underwater pipeline repair mechanism includes a sealing component 1, which includes a sealing plate 11. A sealing gasket 12 is fixed on one side of the sealing plate 11. When the underwater pipeline ruptures, the rupture can be cut to a suitable size so that the sealing plate 11 can be inserted into the rupture, thereby sealing the rupture from the inside of the pipeline. The sealing gasket 12 ensures that no water flows out between the sealing plate 11 and the rupture of the pipeline.

[0040] A support buckle 13 is fixed to one side of the sealing plate 11. A pull cable 14 passes through the support buckle 13. Both ends of the pull cable 14 are fixed to the ends of the clamp 15. The clamp 15 is existing technology. By installing the clamp 15 on the surface of the damaged pipe, the clamp 15 is gradually tightened, which allows the clamp 15 to pull the pull cable 14, which in turn pulls the support buckle 13. This causes the support buckle 13 to drive the sealing plate 11 to squeeze the sealing gasket 12, so that the sealing gasket 12 is tightly attached to the inner wall of the damaged pipe.

[0041] A support base 16 is fixed on one side of the sealing plate 11. A compression bolt 17 is rotatably connected to the support base 16 by a thread. There are two support bases 16 and compression bolts 17.

[0042] By rotating the compression bolt 17, the end of the compression bolt 17 can be squeezed against the rupture side of the pipe, thereby positioning the sealing plate 11 and preventing the sealing plate 11 from shifting.

[0043] The protective component 2 is disposed on the surface of the pipe and includes a protective element 21 disposed on the surface of the pipe. The protective element 21 includes a top protective shell 211 and a bottom protective shell 212. Both the top protective shell 211 and the bottom protective shell 212 have binding grooves 211-1 on their surfaces. There are multiple binding grooves 211-1. The top protective shell 211 and the bottom protective shell 212 can be fixed by using clamps through the binding grooves 211-1. The clamps are not shown in the figure. A flange connection can also be provided here to make the connection between the top protective shell 211 and the bottom protective shell 212 tighter. The flange connection method is existing technology and will not be described in detail here.

[0044] The inner walls of the top protective shell 211 and the bottom protective shell 212 are provided with slots for placing sealing strips. Under the compression of the clamp, the top protective shell 211 and the bottom protective shell 212 can be locked onto the pipe surface, thereby isolating the damaged part of the pipe from the outside.

[0045] A drain hole 212-1 is provided inside the bottom protective shell 212. A first sealing plug 213 is fixed inside the drain hole 212-1 by threads. When the first sealing plug 213 is opened, air is blown into the top protective shell 211, which can squeeze the water in the top protective shell 211 and the bottom protective shell 212, thereby squeezing the water in the top protective shell 211 and the bottom protective shell 212 out through the drain hole 212-1.

[0046] An exhaust pipe 214 is fixed inside the top protective shell 211. A second sealing plug 215 is fixed to the end of the exhaust pipe 214 by threads. By opening the second sealing plug 215, the gas inside the top protective shell 211 and the bottom protective shell 212 can be discharged from the exhaust pipe 214. An injection tube 216 is fixed inside the top protective shell 211. A third sealing plug 217 is fixed to the end of the injection tube 216 by threads. By opening the third sealing plug 217, air or sealant can be injected into the top protective shell 211 by the injection tube 216.

[0047] In use, first open the first sealing plug 213 at the drain hole 212-1, then open the third sealing plug 217. Inject air into the top protective shell 211 through the injection tube 216, causing the air to squeeze the water in the top protective shell 211 and bottom protective shell 212 out through the drain hole 212-1. Insert the first sealing plug 213 into the drain hole 212-1, open the second sealing plug 215, and simultaneously inject sealant into the top protective shell 211 and bottom protective shell 212 through the injection tube 216. The sealant will first fall into the pipe rupture, i.e., above the sealing plate 11. When the pipe rupture is filled with sealant, the sealant will flow into the bottom protective shell 212, and then gradually fill the gap between the bottom protective shell 212, top protective shell 211 and the pipe to prevent leakage from the pipe rupture again. Then, plug in the second sealing plug 215 and the third sealing plug 217.

[0048] Example 2, refer to Figure 2 , Figure 4 , Figure 5 and Figures 8-16 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0049] Specifically, the protective component 2 also includes an absorbent component 22 disposed on the top protective shell 211. The absorbent component 22 includes a lifting plate 221 disposed on one side of the inner wall of the top protective shell 211. A connecting plate 222 is disposed at the bottom of the lifting plate 221. A sponge 223 is fixed on one side of the connecting plate 222. The lifting plate 221 can drive the sponge 223 to descend through the connecting plate 222, so that the sponge 223 can absorb the water accumulated above the sealing plate 11 at the rupture of the pipe. Here, the sponge 223 can be replaced by a compressible and resilient highly absorbent material.

[0050] A breakthrough needle 224 is fixed at the bottom of the lifting plate 221. A row of breakthrough needles 224 are arranged. The breakthrough needles 224 penetrate the connecting plate 222. The sponge 223 is provided with a slot to accommodate the breakthrough needles 224. An isolation membrane 225 is fixed on the inner wall of the top protective shell 211. The isolation membrane 225 isolates the sponge 223, so that the sponge 223 will not absorb water during the installation of the top protective shell 211 onto the pipe, thus ensuring the dryness of the sponge 223.

[0051] At this time, the isolation membrane 225 compresses the sponge 223, so that the sponge 223 is in a compressed state. When the lifting plate 221 moves downward, the penetration needle 224 can penetrate the isolation membrane 225. Through the penetration of the isolation membrane 225 by a row of penetration needles 224, the sponge 223 can break through the seal of the isolation membrane 225 when the lifting plate 221 descends. The side of the penetration needle 224 is provided with a cutting blade, making it easier to break through the isolation membrane 225.

[0052] The inner wall of the top protective shell 211 is fixed with a positioning plate 226. There are two positioning plates 226. When installing the top protective shell 211, the two positioning plates 226 are inserted into the damaged part of the pipe to position the top protective shell 211. After the top protective shell 211 is installed, the sponge 223 is located above the sealing plate 11, so that it can absorb the water accumulation above the sealing plate 11.

[0053] The protective assembly 2 also includes a drive component 23 disposed on the top protective shell 211. The drive component 23 includes a support shell 231 disposed on the top protective shell 211. A first slide rod 232 and a second slide rod 233 slide within the support shell 231. The first slide rod 232 slides within the top protective shell 211. A connecting seat 234 is fixed to the top of the lifting plate 221. The end of the first slide rod 232 is rotatably connected to the connecting seat 234. Two connecting posts 235 slide within the second slide rod 233. The connecting posts 235 are inserted into the connecting seat 234, so that the second slide rod 233... It can rotate relative to the connecting seat 234 and cooperate with the first slide rod 232 to make the first slide rod 232 and the second slide rod 233 rise and fall synchronously, which can drive the lifting plate 221 to move up and down. A swing rod 236 is fixed on one side of the connecting column 235, and the other end of the swing rod 236 is fixed to the inner wall of the second slide rod 233. A first spring 237 is provided inside the connecting column 235. The first spring 237 is in a compressed state. Through the elastic force of the first spring 237, the connecting column 235 can be kept in the connecting seat 234, thereby ensuring the connection between the second slide rod 233 and the connecting seat 234.

[0054] The driving component 23 also includes a lifting bar 238 fixed to the ends of the first slide bar 232 and the second slide bar 233. A first rack 239 is fixed to the bottom of the lifting bar 238. A rotating shaft 2310 is rotatably connected inside the support shell 231. A first gear 2311 is fixed to the surface of the rotating shaft 2310. The first gear 2311 and the first rack 239 mesh. A handle 2312 is fixed to the end of the rotating shaft 2310.

[0055] By rotating the handle 2312, the first gear 2311 can be driven to rotate through the rotating shaft 2310, thereby causing the first gear 2311 to drive the first rack 239 to move into the support shell 231, thereby driving the lifting bar 238 to move towards the top protective shell 211, so that the first slide bar 232 and the second slide bar 233 drive the lifting plate 221 to move towards the sealing plate 11.

[0056] Example 3, referring to Figures 1-16 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0057] Specifically, the protective component 2 also includes a release component 24 disposed on the drive component 23. The release component 24 includes a sliding sleeve 241 that slides on the surface of the second slide rod 233. The sliding sleeve 241 slides within the top protective shell 211 and the support shell 231. A sealing mechanism is provided at the connection between the first slide rod 232 and the sliding sleeve 241 and the protective shell 211 and the support shell 231 so that leakage will not occur at the relatively sliding position.

[0058] A pressing plate 242 is fixed to one side of the swing rod 236. By moving the sliding sleeve 241, the sliding sleeve 241 can press the two pressing plates 242, thereby causing the two pressing plates 242 to drive the two swing rods 236 to bend. This causes the swing rods 236 to drive the connecting column 235 to move out of the connecting seat 234, thereby causing the end of the second sliding rod 233 to separate from the connecting seat 234. A torsion spring is provided at the connection between the first sliding rod 232 and the connecting seat 234. Through the restoring elastic force of the torsion spring, when the end of the second sliding rod 233 is separated from the connecting seat 234, the lifting plate 221 can rotate around the connecting seat 234 at the end of the first sliding rod 232 as a fulcrum, thereby moving away from the end of the second sliding rod 233. A stop block 2416 is fixed to one side of the lifting plate 221. When the stop block 2416 hits the surface of the first sliding rod 232, the lifting plate 221 stops rotating.

[0059] The release component 24 also includes a through hole 241-1 opened on the sliding sleeve 241 and the second sliding rod 233. A rod 243 is inserted into the through hole 241-1. By setting the rod 243, the sliding sleeve 241 and the second sliding rod 233 can move up and down synchronously.

[0060] A limiting plate 244 is fixed to the surface of the insertion rod 243. A sliding groove 231-1 and a take-out groove 231-2 are provided in the support shell 231. When the sliding sleeve 241 and the second sliding rod 233 move up and down, the limiting plate 244 can slide in the sliding groove 231-1, thereby preventing the insertion rod 243 from accidentally moving out of the sliding sleeve 241. When the lifting plate 221 needs to be flipped, the limiting plate 244 is moved to the side of the take-out groove 231-2. At this time, the insertion rod 243 can be pulled, so that the limiting plate 244 moves into the take-out groove 231-2. At this time, the insertion rod 243 is pulled out of the sliding sleeve 241 and the second sliding rod 233, so that the sliding sleeve 241 and the second sliding rod 233 can slide relative to each other. At this time, pushing the sliding sleeve 241 can make the sliding sleeve 241 press against the pressing plate 242, thereby disconnecting the connection between the end of the second sliding rod 233 and the connecting seat 234.

[0061] The release component 24 also includes a positioning block 245 that slides within the first slide bar 232. A second spring 246 is fixed within the positioning block 245. The second spring 246 is in a compressed state. A positioning groove 234-1 is provided within the connecting seat 234. When the lifting plate 221 flips and causes the stop block 2416 to strike the surface of the first slide bar 232, the positioning block 245 will be inserted into the positioning groove 234-1 to position the state of the lifting plate 221.

[0062] The release component 24 also includes a second gear 247 fixed to the surface of the first slide bar 232, and a second rack 248 sliding inside the lifting plate 221, with the second gear 247 and the second rack 248 meshing.

[0063] When the lifting plate 221 flips, the first slide rod 232 can drive the second gear 247 to rotate, thereby driving the second rack 248 to slide.

[0064] The release component 24 also includes a rotating seat 249 fixed to the surface of the lifting plate 221. A threaded sleeve 2410 is rotatably connected inside the rotating seat 249. A third gear 2411 is fixed on the surface of the threaded sleeve 2410. The third gear 2411 meshes with the second rack 248. When the second rack 248 moves, it can drive the third gear 2411 to rotate, thereby driving the threaded sleeve 2410 to rotate.

[0065] A slide block 2412 is fixed on the surface of the lifting plate 221. A limit pin 2413 slides inside the slide block 2412 and cannot rotate inside the slide block 2412.

[0066] The two limit pins 2413 are rotatably connected by a thread and a threaded sleeve 2410. When the threaded sleeve 2410 rotates, the two limit pins 2413 can move closer to or further away from each other.

[0067] A connecting sleeve 2414 is fixed on one side of the connecting plate 222. The connecting sleeve 2414 is inserted into the lifting plate 221. A limiting hole 2414-1 is opened on the surface of the connecting sleeve 2414. The end of the limiting pin 2413 is inserted into the limiting hole 2414-1, so that the connecting plate 222 can be fixed on one side of the lifting plate 221.

[0068] A third spring 2415 is fixed inside the lifting plate 221. When the third spring 2415 is in a compressed state, the two limit pins 2413 can be pulled out of the limit hole 2414-1 by rotating the threaded sleeve 2410. At this time, under the reset force of the two third springs 2415, the connecting plate 222 can be pushed to move the sponge 223 away from the lifting plate 221. At this time, the sponge 223 will be bounced into the gap between the top protective shell 211 and the pipe, and then slide down to the bottom wall of the bottom protective shell 212.

[0069] When an underwater pipeline ruptures, the affected section is cleaned, and the rupture opening is cut to a suitable size so that the sealing plate 11 can be inserted into it, thus sealing the rupture from the inside of the pipeline. Tightening the clamp 15 pulls the cable 14, which in turn pulls the support buckle 13. This causes the support buckle 13 to push the sealing plate 11 against the sealing gasket 12, making the sealing gasket 12 adhere tightly to the inner wall of the damaged pipeline, thus sealing the rupture. Then, rotating the compression bolt 17 causes the end of the compression bolt 17 to press against the rupture side of the pipeline, thereby positioning the sealing plate 11 and preventing it from shifting.

[0070] Then, place the top protective shell 211 on the pipe and insert the two positioning plates 226 into the damaged part of the pipe to position the top protective shell 211. After the top protective shell 211 is installed, the sponge 223 is located above the sealing plate 11, so that it can absorb the water accumulated above the sealing plate 11.

[0071] The top protective shell 211 and the bottom protective shell 212 are fixedly connected by multiple clamps. At this time, the first sealing plug 213 at the drain hole 212-1 is opened, and then the third sealing plug 217 is opened. Air is injected into the top protective shell 211 through the injection tube 216, so that the air squeezes the water in the top protective shell 211 and the bottom protective shell 212 out through the drain hole 212-1. The first sealing plug 213 is inserted into the drain hole 212-1, and the third sealing plug 217 is inserted into the injection tube 216.

[0072] At this time, turning the handle 2312 will drive the first gear 2311 to rotate through the rotating shaft 2310, thereby causing the first gear 2311 to drive the first rack 239 to move into the support shell 231, thereby driving the lifting bar 238 to move towards the top protective shell 211, so that the first slide bar 232 and the second slide bar 233 drive the lifting plate 221 to move towards the sealing plate 11.

[0073] The lifting plate 221 drives the breakthrough needles 224 to penetrate the isolation membrane 225. Through the penetration of the isolation membrane 225 by a row of breakthrough needles 224, the lifting plate 221 descends and drives the sponge 223 to break through the seal of the isolation membrane 225. At this time, the sponge 223 is released from compression and rebounds. As the lifting plate 221 moves, the sponge 223 can absorb the water accumulated above the sealing plate 11. At this time, there is no water accumulation above the sealing plate 11.

[0074] Reverse rotation of handle 2312 causes lifting plate 221 to move sponge 223 away from sealing plate 11, causing limiting plate 244 to move to one side of take-out slot 231-2. At this time, insert rod 243 can be pulled, causing limiting plate 244 to move into take-out slot 231-2. Insert rod 243 pulls out sliding sleeve 241 and second sliding rod 233, allowing sliding sleeve 241 and second sliding rod 233 to slide relative to each other. Pushing sliding sleeve 241 can cause sliding sleeve 241 to press against squeezing plate 242, thereby disconnecting the end of second sliding rod 233 from connecting seat 234.

[0075] With the torsion spring provided at the connection between the first slide rod 232 and the connecting seat 234, when the end of the second slide rod 233 is separated from the connecting seat 234, the lifting plate 221 can rotate around the connecting seat 234 at the end of the first slide rod 232 as a fulcrum, thereby moving away from the end of the second slide rod 233. When the stop block 2416 hits the surface of the first slide rod 232, the lifting plate 221 stops rotating. At this time, the positioning block 245 will be inserted into the positioning groove 234-1 to position the state of the lifting plate 221, so that the lifting plate 221 will not shake.

[0076] While the lifting plate 221 rotates, the first slide rod 232 can drive the second gear 247 to rotate, thereby driving the second rack 248 to slide. When the second rack 248 moves, it can drive the third gear 2411 to rotate, thereby driving the threaded sleeve 2410 to rotate. When the threaded sleeve 2410 rotates, it can cause the two limit pins 2413 to move closer to each other, thereby causing the two limit pins 2413 to be pulled out of the limit hole 2414-1. At this time, under the reset force of the two third springs 2415, the connecting plate 222 can be pushed to move the sponge 223 away from the lifting plate 221. At this time, the sponge 223 will be bounced into the gap between the top protective shell 211 and the pipe, and then slide down to the inner bottom wall of the bottom protective shell 212.

[0077] At this point, open the third sealing plug 217 and the second sealing plug 215, and inject sealant into the top protective shell 211 and the bottom protective shell 212 through the injection tube 216. During this process, the air between the bottom protective shell 212 and the top protective shell 211 will be discharged from the exhaust pipe 214.

[0078] The sealant first falls from the nozzle of the injection tube 216 into the rupture of the pipe, that is, above the sealing plate 11. When the rupture of the pipe is filled with sealant, the sealant will flow into the bottom protective shell 212 and then gradually fill the gap between the bottom protective shell 212, the top protective shell 211 and the pipe to prevent leakage from the rupture of the pipe again. Then, the second sealing plug 215 and the third sealing plug 217 are plugged in.
