Description

An online quick repair device for ruptured pipelines

technical field

The utility model relates to the technical field of repairing broken pipelines, in particular to an online rapid repair device for broken pipelines.

Background technique

Oil, gas or water supply and drainage pipelines, due to material aging or creep, will cause partial cracking and leakage under internal high pressure, leaving potential safety hazards. If it is not repaired in time, it will cause serious losses and even endanger people's safety. Simple repair methods generally use partial interception or entire segment replacement, but this method is a waste of resources.

Targeted restoration with restoration devices can effectively save resources and avoid waste. Existing adopt repairing device to repair the method that mainly contains following several kinds:

(1) A cylinder composed of two semicircular shells is used to cover the shell to be protected or repaired to form a closed cavity, and the molten plastic is injected into the formed cavity through the injection hole on the shell wall Seal the cavity and repair the rupture. This kind of semicircular shell has a fixed size. Pipelines with different diameters need to be equipped with semicircular shells with corresponding pipe diameters. The versatility is not high, and it is inconvenient to replace and lock. At the same time, the landfill space around the pipeline is greatly damaged.

(2) Use a pair of Huff steel plates and a pair of rubber seals, clamp the steel plates and seals on the ruptured part of the pipeline with bolts, make the seals elastically deform, and form a seal between the steel plate and the ruptured pipeline, so as to repair the pipeline the goal of. In addition to the disadvantages of the above-mentioned method, this method has a heavy component weight, the steel plate cannot be removed, and the stability of the mechanical seal is not strong.

(3) Use hydraulic devices to fix and clamp the ruptured pipeline and the repaired pipeline, and use the seal to repair. The principle of this method is simple, the structure of the device is complicated, and the actual construction is very inconvenient, and it is easy to cause pollution of the pipeline.

Utility model content

The utility model overcomes the deficiencies in the prior art, and provides an on-line rapid repair device for ruptured pipelines with a simple structure.

In order to achieve the above purpose, the following technical solutions are adopted:

An on-line rapid repair device for a ruptured pipeline, the repair device includes a coated steel strip and a standardized plastic block, the standardized plastic block is wrapped on the outer surface of the pipeline, the coated steel strip is wrapped on the standardized plastic block, the standardized plastic block and the package The steel-clad strip and the two surfaces in contact with the pipe are curved surfaces. The standardized plastic block includes a cushion block and a power access block. Resistance wire connection.

In the above solution, the standardized plastic block also includes a connection block and an indirect electric frit, both of which are provided with wires inside, and the power access block and the indirect electric frit are connected through the connection block, The connection between the power access block and the connecting block and between the connecting block and the indirect electric fusing block is realized through the cooperation of the copper-inlaid guide sleeve and the copper-inlaid guide post.

In the above solution, the coated steel strip has small holes, the standardized plastic block is provided with a buckle structure matching the small holes, and the coated steel strip is provided with a quick locking device.

Compared with the prior art, the utility model has the advantages of simple structure, convenient use, strong sealing stability and high versatility.

Description of drawings

Fig. 1 is the utility model schematic diagram.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Fig. 1 of the utility model, the crack 6 of the pipeline 4 is below the landfill layer, and maintenance is inconvenient. An indirect electric frit 5, a matching power supply access block 12, several connection blocks 10 and pads can be selected. Block 3, according to the diameter of the pipeline 4 to be repaired, roughly select the material, size and quantity of the corresponding cladding steel strip 2 and pad 3.

First insert the buckle of the spacer 3 onto the coated steel belt 2, place the power access block 12 at a place where it is easier to access the power supply, and cover the indirect electric frit 5 on the rupture 6, connect the power supply block 12 and the indirect electric A complete current loop is formed between the frits 5 through several connection blocks 10, between the power supply block 12 and the connection block 10, between two connection blocks 10, and between the connection block 10 and the indirect electric frit 5. The copper-embedded guide sleeve and guide post cooperate with the structure 9 to form a connection. Wrap the coated steel strip 2 around the pipe 4 for a week, and under the action of external force, the upper and lower surfaces of each plastic block are tightly pressed against the coated steel strip 2 and the surface 4 of the pipe respectively, and the quick locking device 1 locks the whole device form a closed loop to fix and support the cracks in the pipe 4, connect the terminal 7 to an external current, and the resistance wire 8 generates heat to melt the indirect electric frit 5, and the molten plastic on the lower surface of the indirect electric frit 5 flows into the Rupture 6, it is repaired, and itself is also welded on the pipeline 4 simultaneously.
