Description

Technical Field

[0001] The utility model belongs to the field of pipeline repair, in particular to a device for on-site repair of pipeline breakage. Background Art

[0002] During long-term use, pipelines for life and industry are prone to leakage problems caused by partial breakage. To ensure the normal use of the pipeline and avoid long-term impact on life and production, clamps are often used in the prior art to repair the broken parts of the pipeline.

[0003] To ensure the stability of the repair, the clamp is a structural member made of metal, which results in the situation that in some cases, the clamp cannot fully fit the pipeline, causing gaps between the clamp and the pipeline, thus resulting in slight leakage of the pipeline.

[0040] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0041] As Figure 1-5 shown: A field repair device for pipeline breakage, comprising:

[0042] A housing 1, the housing 1 is an arc-shaped structural member, and a plurality of housings 1 form an annular structure wrapped around the outer side of the pipeline. The inner side wall of the housing 1 is in close fit with the outer side wall of the pipeline;

[0043] An airbag 2, the airbag 2 is arranged on the inner side wall of the housing 1;

[0044] An air hole 101 is formed on the housing 1. An air supply assembly 3 is arranged inside the airbag 2. The air hole 101 is communicated with the air supply assembly 3. One end of the air hole 101 away from the air supply assembly 3 is communicated with a gas supply device, and a one-way valve is arranged in the air hole 101.

[0045] Cover the airbag 2 on the outer wall of the damaged pipeline through the housing 1, and use the air supply device to supply air into the airbag 2. The airbag 2 bulges and presses tightly against the outer wall of the damaged pipeline, achieving a tight fit between the repair device and the damaged pipeline, and avoiding leakage problems caused by the failure of the repair device to fully fit the outer wall of the pipeline; the airbag 2 realizes the sealing function to prevent secondary damage caused by over-tightening of the repair device in order to ensure that the damaged pipeline no longer leaks.

[0046] The above-mentioned airbag 2 can be replaced with a sheet-like structural member of the same material, and the edge part of the sheet-like structural member is tightly adhered to the inner wall of the housing 1, and a sealed cavity is formed between the sheet-like structure and the housing 1.

[0047] In some embodiments, the airbag 2 is soft in texture and rough on the outer surface.

[0051] In other embodiments, the clamping block 4 can be replaced with other fixtures that can clamp the connecting plate 102 or the housing 1.

[0052] In some embodiments, the gas delivery assembly 3 includes a connection block 301, a connection pipe 302, and an arc-shaped pipe 303. A main air passage 304 communicating with the air hole 101 is formed in the connection block 301. The connection pipes 302 are fixed on both sides of the connection block 301 and communicate with the main air passage 304. One end of the connection pipe 302 away from the connection block 301 is closed. There are multiple arc-shaped pipes 303, and all the arc-shaped pipes 303 communicate with the connection pipe 302. A connection groove corresponding to the connection block 301 is formed on the inner side wall of the housing 1.

The multiple housings 1 are preliminarily connected through the connection holes 103, and the clamping blocks 4 are used to further stabilize the housing 1 to improve the connection stability of the housing 1. At this time, the sealing strip 5 deforms under the pressure of the housing 1, and the sealing strip 5 presses against the outer wall of the pipeline, enabling the housing 1 to better seal the damaged part;

[0063] After the installation is completed, the staff turns on the air pump. Under the operation of the air pump, the gas flows into the airbag 2 until the outer surface of the airbag 2 completely presses against the pipeline. At this time, the inflation stops, and the outer surface of the airbag 2 achieves complete sealing of the pipeline. And under the action of the one-way valve, the gas will not flow out. The staff removes the air supply pipe to complete the pipeline repair; at this time, the pipeline can be used normally and is sufficient to support the subsequent replacement and repair project.

[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present embodiments, and they should all be covered by the scope of the claims and the description of the present invention.
