Description

Automatic sealing mechanism of non-excavation petroleum pipeline damage prosthetic devices

Technical Field

The invention relates to the technical field of pipeline maintenance and repair, in particular to an automatic sealing mechanism of a trenchless petroleum pipeline damage repairing device.

Background

With the development of the oil industry, more and more pipelines are applied to the field of oil transportation, and the pipelines are difficult to avoid corrosion and cracking in long-term use, and at this time, the repair of the pipelines is very important. The repair of pipelines is divided into an excavation type repair method and a non-excavation type repair method, wherein the excavation type repair method is high in repair cost, and the non-excavation type repair method can effectively save the cost.

The existing trenchless repairing method mainly comprises an ultraviolet curing repairing technology, a point repairing technology, a folding lining repairing technology and a high polymer material repairing technology.

1. Ultraviolet curing repair technology (for whole repair)

The ultraviolet curing CIPP repairing technology is characterized in that under the condition that the position of a pipeline to be repaired is not changed, a hose soaked with resin is tightly attached to the inner wall of the pipeline to be repaired in a stretching and compressed air mode or process, then the characteristic that the resin in the hose is cured when meeting ultraviolet rays is utilized, an ultraviolet lamp is placed into an inflated hose and is controlled to run in the hose at a certain speed, the hose is gradually cured from one end to the other end and is tightly attached to the inner wall of the pipeline to be repaired, a hard pipe-in-pipe structure is formed, and therefore an underground pipeline which is damaged or loses the conveying function is repaired in situ.

2. Point repair technology (for local repair)

The trenchless spot repairing method for urban pipelines, also called local resin curing method (felt tube air bag local forming method), is a trenchless repairing method in which when emergency repair is required due to local damage of a pipeline in the case of local crack, leakage and damage of the pipeline, a glass fiber felt cloth coated with a resin mixed solution is pressed against the inner wall of the pipeline by an air bag, and curing is realized by means of normal temperature, heating or ultraviolet irradiation, etc., so that a new lining pipe is formed in a repairing point pipe. The point-like repair technology has the characteristics of strong pertinence, high construction speed and the like, does not need to repair the whole section, only needs to repair the damaged part, and can greatly reduce the economic cost by adopting the method, so the technology is widely applied to foreign pipeline repair engineering.

3. Folding lining repair technology (for integral repair)

The Primeris lining system consists of Kevlar reinforced lining pipes and specially designed connectors, the PE pipes are folded into a U shape and pulled into the mother pipes by binding with adhesive tapes, and then the pipes are inflated to form a circle.

4. Polymer material repair technology (for local repair)

The high polymer material repairing technology adopts a concrete repairing material imported from America Annaikang, and mainly aims at pipelines with the diameter of more than 700 mm. After the damaged position is determined, constructors can complete the procedures of quick leaking stoppage, filling, bridging, reinforcing and the like at one time, the construction is simple, the material has quick curing time, the compressive strength after curing is 5 times of that of concrete, the cohesive strength of the material and the original pipe wall is greater than that of the concrete, and the material has good chemical corrosion resistance.

The existing point-like repair technology needs to guide a device entering the pipeline for operation by arranging a traction mechanism, and the device cannot be conveniently and efficiently adjusted in adaptability aiming at pipelines with different diameters;

meanwhile, in the process of sealing the pipeline, because the inner wall of the pipeline has more impurities, the repairing effect of repairing modes such as gluing and the like is poor, and meanwhile, after the repairing is finished, certain impact can be caused to the repaired position due to the flowing process of the petroleum in the pipeline, so that the repairing effect is low.

The working principle of the invention is as follows:

the power supply is used for independently supplying power for the visual monitoring mechanism 2, the telescopic adjusting mechanism 3, the travelling mechanism 4 and the air pump, and can also supply power in a mode of external wires.

The operator soaks the slurry for repairing with the glass fiber felt cloth 8, and then wraps the glass fiber felt cloth 8 outside the air bag 7. The staff places the device to the one end of the petroleum pipeline that needs to be repaired earlier, then sends the signal to flexible adjustment mechanism 3 through the controller.

After receiving the signal, the telescopic adjusting mechanism 3 drives the parts of the telescopic adjusting mechanism located at the two ends of the main shaft shell 1 to synchronously extend outwards in the radial direction until the tail end of the visual monitoring mechanism 2 abuts against the inner wall of the petroleum pipeline and is located on the same axis with the petroleum pipeline.

The controller then sends a signal to the travelling mechanism 4, and the travelling mechanism 4 starts to work as the whole device to provide driving force for advancing in the pipeline after receiving the signal. The visual signal is sent to the controller by observation of the visual monitoring mechanism 2 which has an infrared function and can rotate.

The controller accurately positions the internal damage of the petroleum pipeline according to the data sent by the vision monitoring mechanism 2. When the spindle housing 1 moves to the damaged part of the pipeline, the controller sends a signal to the air pump 5, the air pump 5 injects air into the air bag 7 after receiving the signal, and the air bag 7 expands and gradually enables the external glass fiber felt cloth 8 to abut against the damaged part of the pipeline.

When the glass fiber felt cloth 8 is bonded with the damaged part of the pipeline, the controller sends a signal to the air pump 5, the air pump 5 pumps out the air in the air bag 7 to enable the air bag to contract so as to be separated from the glass fiber felt cloth 8, and the glass fiber felt cloth 8 is left at the damaged part of the inner wall of the pipeline to finish the repairing task. Then the controller sends a signal to the travelling mechanism 4, and the travelling mechanism 4 receives the signal and then the whole driving device climbs out of the petroleum pipeline.
