Description

Technical Field

[0001] The present invention relates to the technical field of ship pipeline repair, and particularly to a rapid plugging repair device for ship pipelines and a repair method thereof. Background Art

[0002] At present, there are a large number of pipelines for transporting media such as water supply, oil supply and gas on ships. During use, due to reasons such as ship failures, impacts and equipment aging, these pipelines are prone to breakage and fracture failures, seriously threatening the safe use of ships. Therefore, in response to pipeline leakage or fracture failures, corresponding repair devices need to be used for repair.

[0003] Existing rapid plugging repair measures for ship pipelines mainly include welding leak repair, shutting down the machine to replace pipe segments, clamp sealing, tape winding, etc. In actual use, the measures of welding leak repair and shutting down the machine to replace pipe segments need to interrupt the pipeline operation, affecting the operation efficiency of the ship, and the operation is complex and time-consuming. The measures of clamp sealing and tape winding have problems such as insufficient sealing pressure and poor adaptability. For some important pipelines on ships, it is necessary to keep them unobstructed to ensure the safe operation of the ship. To solve the problem that traditional sealant plugging equipment cannot effectively meet the needs of emergency repair work after pipeline breakage or fracture, a rapid plugging repair device for ship pipelines and a repair method thereof are proposed for emergency repair of pipelines. Through the synergistic effect of mechanical locking and inflatable sealing, combined with pressure regulation, rapid emergency repair of pipeline leakage can be achieved. The plugging repair device can be set with different matching models according to the pipeline diameter, and different models of repair devices can be quickly selected for pipeline plugging repair work when repairing pipelines with different diameters. The operation is simple, significantly improving the ship repair efficiency and safety. A bottom support bracket is provided to prevent further damage to the damaged and aged pipeline due to the self-weight of the repair device, enabling rapid plugging repair of the aged and leaking pipelines on the ship. Summary of the Invention

[0004] The present invention provides a rapid plugging repair device for ship pipelines and a repair method thereof, solving the problems raised in the above-mentioned background art, enabling rapid and safe plugging repair of the aged and leaking pipelines on the ship.

[0005] The solution of the present invention to the above technical problems is as follows: A rapid plugging and repairing device for ship pipelines, including a first hoop member, a second hoop member, an internal airbag, a load-bearing base, a bottom bracket, and a side seal ring. The first hoop member and the second hoop member are rotatably connected. The first hoop member and the second hoop member are both fixedly installed with flange edges and connecting side plates. The load-bearing base and the bottom bracket can be connected by screws. The load-bearing base is fixedly installed with a load-bearing cylinder. The load-bearing cylinder is slidably connected with a load-bearing bottom rod. The load-bearing bottom rod is threadedly connected with a positioning screw. The load-bearing bottom rod is fixedly connected with a bottom support plate. The internal airbag is fixedly communicated with a one-way air valve and a pressure sensor. The second hoop member is fixedly communicated with a pressure relief valve and a sealant input pipe. The side seal ring is placed at the gap between the adjacent first hoop member and the second hoop member. The side seal ring and the flange edge are both provided with bolt holes. A strip-shaped gasket is arranged at the gap between the adjacent connecting side plates. The internal airbag is provided with a through-hole corresponding to the pressure relief valve. The pressure relief valve passes through the through-hole;

[0006] The repair method includes the following steps:

[0007] S1: Leak location and pretreatment: Use an infrared thermal imager to locate the leak point, grind and clean the rust and impurities on the surface of the ship pipeline wall. According to the area of the leak point, the adjacent flange edges can be connected by bolts so that the repair device can be assembled and connected to increase the length, so that the repair device can cover a larger width of the leak point;

[0008] S2: Installation of the repair device: Unscrew the first hoop member and the second hoop member and expand them to be sleeved on the pipeline, adjust to the center position of the leak point, with the pressure relief valve corresponding to the leak. After rotation and closure, the internal airbag can be sleeved on the leak point. Positioning can be carried out by connecting the connecting side plates with bolts. Inflate the internal airbag through the one-way air valve. The internal airbag expands to 0.5 - 1.5 MPa, fits against the pipe wall to form a preliminary seal, and inject high-temperature resistant epoxy resin glue through the sealant input pipe to fill the micro-gap for secondary seal;

[0009] S3: The extrusion pressure of the internal airbag can be monitored in real time through the pressure sensor. When the pressure is high, the pressure relief valve can be opened for pressure relief, and gas can be supplemented as needed;

[0010] S4: Loosen the positioning screw, and the load-bearing bottom rod can be telescopically adjusted in length from the load-bearing cylinder. Fit the arc-shaped structure at the top of the bottom bracket against the hoop formed by the first hoop member and the second hoop member, and tighten the positioning screw. Then the bottom support plate can be placed on the ground, and the bottom bracket and the hoop on the top are supported, so that the repair device can be stably placed at the pipeline for plugging and repairing.

[0011] Based on the above technical solutions, the present invention can also be improved as follows.

[0012] Furthermore, the top of the bottom bracket is set as an arc structure, so that the bottom bracket can support by fitting the clamp composed of the first clamp and the second clamp.

[0013] Furthermore, the bearing base is provided with a placement groove corresponding to the bottom bracket, so that the bottom bracket can be inserted into the bearing base for temporary assembly and connected by screws.

[0014] Furthermore, the first clamp and the second clamp are both provided with limiting grooves corresponding to the built-in airbag, and the built-in airbag is placed in the limiting groove. The built-in airbag can expand in the limiting grooves of the first clamp and the second clamp, so as to block and repair the leakage point of the ship pipeline.

[0015] Furthermore, the outer walls of the first clamp and the second clamp are both provided with nano-hydrophobic coatings, which can effectively improve the corrosion resistance and are more suitable for the corrosive marine ship environment.

[0016] Furthermore, the one-way air valve and the sealant input pipe are both threadedly connected with sealing caps.

[0017] Furthermore, the bearing cylinder is provided with a strip hole corresponding to the positioning screw, and the positioning screw passes through the strip hole and is threadedly connected with the bearing bottom rod.

[0018] Furthermore, a limiting slider is arranged at the top end of the bearing bottom rod, and the bearing cylinder is slidably connected with the limiting slider.

[0019] The beneficial effects of the present invention are as follows: The present invention provides a ship pipeline rapid plugging and repairing device and its repairing method, which has the following advantages:

[0020] 1. Such a repairer structure can be quickly assembled, so that it can cover a larger width of pipeline leakage scenarios according to needs, and has good applicability;

[0021] 2. Through the synergistic effect of mechanical locking and airtight inflation, combined with pressure regulation, rapid emergency repair of pipeline leakage can be realized. The plugging and repairing device can be set with different matching models according to the pipeline diameter, and different models of repairers can be quickly selected for pipeline plugging and repairing work when repairing pipelines with different diameters, with simple operation, significantly improving the ship maintenance efficiency and safety;

[0022] 3. A bottom support bracket is provided to support the installed repairer, which can prevent the damaged and aging pipeline from being further damaged due to the self-weight of the repairer, so that the aging and leaking pipeline of the ship can be quickly plugged and repaired.
