Abstract
The invention relates to a contractible pipeline. The contractible pipeline is tubular and is made of an elastic material; the section of the contractible pipeline is mainly composed of thick portions and thin portions; the thickness of the thick portions is larger than that of the thin portions; the thick portions are connected with the thin portions through recessed portions; a wire, a signal line and the like can be inserted into an area enclosed by the thick portions and the thin portions. Since the contractible pipeline comprises the thick portions and the thin portions, in a free state, the section of the contractible pipeline is approximate to a regular polygon; when air in the area enclosed by the thick portions and the thin portions is pumped out or is pressed out by means of external pressure, the thin portions will be recessed towards the central area because that the structural strength of the thin portions is small, and as a result, the projection of the section of the contractible pipeline is shrunken; and since the thick portions and thin portions are distributed in a staggered manner, the thin portions are recessed towards the central area simultaneously. According to the contractible pipeline of the invention, the area of the projection of the section of the contractible pipeline is shrunken, so that the contraction of the pipeline can be realized. The contractible pipeline has the advantages of simple structure and wide use range, and can be widely applied to the fields such as underwater cable construction and optical fiber protection.
Description
Technical field
The present invention relates to a kind of pipeline, especially a kind of Contraction Ducts.
Background technology
Traditional collapsible pipeline is generally pyrocondensation pipeline, and pyrocondensation pipeline is generally permanent deformation, namely can not again get back to original state after pyrocondensation.In some cases, be difficult to accomplish or unnecessary pyrocondensation.As when underwater cabling, need cable to be inserted in protective conduit.If now this protective conduit is pyrocondensation pipeline, then can not reduce after this pyrocondensation pipeline pyrocondensation.Again by the situation that cable is extracted out, then inconvenience is brought for also needing.If with soft pipeline, by hydraulic pressure, air is wherein discharged, then pipeline under water time cross section be flat, be unfavorable for that pipeline is underwater stable.
Summary of the invention
The technical problem mentioned for foregoing and technical need, provide a kind of Contraction Ducts.
The present invention is achieved by the following technical solutions: in a tubular form, for elastomeric material is made, its cross section is formed primarily of thick portion and thin section Contraction Ducts; The Thickness Ratio thin section thickness in thick portion is thick; Thick portion is connected with thin section by sinking portion.Electric wire, holding wire etc. can be inserted in the region surrounded of thick portion and thin section.
The approach of technical solution problem is:
Because Contraction Ducts contains thick portion and thin section, under free state, its cross section presents approximate regular polygon.By both thick portion and thin section around region in air take away or by ambient pressure by air compressing walk time, because the structural strength of thin section is less, thin section caves in central area, thus the projection in its cross section is diminished.Because thick portion and thin section are staggered layouts, each thin section caves in central area simultaneously.
The invention has the beneficial effects as follows: by reducing the size of the sectional area projection of Contraction Ducts, realize the object that pipeline shrinks, structure is simple, of many uses.The fields such as submerged cable construction, fiber optic protection can be widely used in.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is the sectional view after spread apart of the present invention.
Fig. 2 is contractible graph of the present invention.
Wherein:
1-Contraction Ducts, the thick portion of 2-, 3-thin section, 4-thinning part, 5-transition part, 6-sinking portion.
Embodiment
Exemplary embodiment of the present invention is:
A kind of Contraction Ducts, Contraction Ducts 1 one-tenth tubulose, for elastomeric material is made, Contraction Ducts 1 is formed primarily of thick portion 2 and thin section 3; Thickness Ratio thin section 3 thickness in thick portion 2 is thick; Thick portion 2 is connected with thin section 3 by sinking portion 6.Electric wire, holding wire etc. can be imported in the region surrounded of thick portion 2 and thin section 3.
There is thinning part 4 middle part of thin section 3, and thinning part 4 is the most thin section in the whole cross section of Contraction Ducts 1.The thickness of thin section 3 is smoothly thinning from sinking portion 6, until the thickness of thinning part 4.In Contraction Ducts 1 cross section, the quantity of thick portion 2 and thin section 3 is odd number, or in Contraction Ducts 1 cross section, the quantity of thick portion 2 and thin section 3 is even number.The thickness of thin section 3 is 30% to 60% of thick portion 2 segment thickness.
Because Contraction Ducts 1 contains thick portion 2 and thin section 3, under free state, its cross section presents approximate regular polygon.By both thick portion 2 and thin section 3 around region in air take away or by ambient pressure, air compressing walked time, because the intensity of thin section 3 is less, thin section 3, to central area depression, thus makes the projection in its cross section diminish.Because thick portion 2 and thin section 3 are staggered layouts, each thin section 3 caves in central area simultaneously.
The invention has the beneficial effects as follows: by reducing the size of the sectional area projection of Contraction Ducts, realize the object that pipeline shrinks, structure is simple, of many uses.The fields such as submerged cable construction, fiber optic protection can be widely used in.
In addition, embodiments of the present invention are the examples representing content of the present invention, can combine with other known technology further, also can omit a part etc. without departing from the spirit and scope of the invention and carry out changing to form.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
