Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline corrosion protection technology, specifically relating to a segmented corrosion protection sleeve for overhead pipelines. Background Technology
[0002] Overhead pipelines are a type of pipeline erected above the ground or water surface to transport gases or liquids. They typically consist of three parts: a crossing structure, a supporting structure, and a foundation. Because overhead pipelines are directly exposed to the environment, they are susceptible to corrosion due to factors such as moisture, oxygen, and corrosive gases. To ensure the service life of overhead pipelines, anti-corrosion treatment is necessary.
[0003] In existing technologies, the main method for protecting pipelines against corrosion is by applying a coating. While this method can protect overhead pipelines from corrosion, the coating is susceptible to physical damage, peeling, and the inherent corrosion resistance of the material itself, which can lead to a failure in the anti-corrosion effect. As a result, the anti-corrosion protection effect on overhead pipelines is poor.
[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a segmented anti-corrosion protective sleeve for overhead pipelines.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this utility model is to provide a segmented anti-corrosion protective sleeve for overhead pipelines, which can improve the anti-corrosion protection effect of overhead pipelines.
[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0008] A segmented anti-corrosion protective sleeve for overhead pipelines includes: an outer protective sleeve layer, a Velcro closure, a Velcro closure, and a pair of side binding straps. The outer protective sleeve layer is a rectangular component, including two long sides and two short sides. The Velcro closure is fixedly connected to the outer side of one long side of the outer protective sleeve layer, and the Velcro closure is fixedly connected to the other long side of the outer protective sleeve layer and is adapted to the Velcro closure. The pair of side binding straps are respectively fixedly connected to the two short sides of the outer protective sleeve layer for binding the ends of the outer protective sleeve layer.
[0009] In one or more embodiments of this utility model, the outer protective sleeve is made of waterproof nylon fabric. It possesses excellent corrosion resistance and wear-resistant protective properties, improving the effectiveness of the outer protective sleeve in protecting overhead pipelines. Both the Velcro closure and the Velcro fastener are sewn to the outer protective sleeve, ensuring the stability and ease of processing of the connection between the Velcro closure and the outer protective sleeve.
[0010] In one or more embodiments of this utility model, an anti-corrosion inner layer is fixedly connected to the inner side of the outer protective sleeve, and the anti-corrosion inner layer is made of epoxy resin composite material. The anti-corrosion inner layer improves the anti-corrosion protection performance of the outer protective sleeve.
[0011] In one or more embodiments of this utility model, a protective liner is fixedly connected to the inner side of the anti-corrosion inner layer, and the protective liner is made of fiberglass cloth. The use of a protective liner ensures the stability of the assembly connection of the anti-corrosion inner layer and also improves the service life of the outer protective sleeve and the protective liner.
[0012] In one or more embodiments of this utility model, the transverse dimension of the anti-corrosion inner layer and the protective liner is the same as the long side dimension of the outer protective sleeve, and the longitudinal dimension of the anti-corrosion inner layer and the protective liner is smaller than the short side dimension of the outer protective sleeve.
[0013] In one or more embodiments of this utility model, the pair of side drawstrings are hollow components with openings at both ends. The side drawstrings are made of waterproof fabric and are sewn to the short sides of the outer protective sleeve. By tightening the side drawstrings, the two short sides of the outer protective sleeve are tightened for protection, thus improving the effectiveness of the protective sleeve for overhead pipelines.
[0014] In one or more embodiments of this utility model, a fixing strap is inserted inside the side drawstring, and both ends of the fixing strap extend to the outside of the side drawstring. The side drawstring is tightened and fixed by tightening and binding the fixing strap.
[0015] In one or more embodiments of this utility model, multiple sets of tension limiting rings are fixedly connected to the outer side of the outer protective sleeve, with each set containing 3 to 6 tension limiting rings. The outer protective sleeve is then auxiliaryly bound by tensioning and limiting the multiple sets of tension limiting rings.
[0016] In one or more embodiments of this utility model, the tension limiting ring is an annular component with openings on both sides, and a binding strap is inserted inside each set of tension limiting rings. By binding the binding strap, the anti-corrosion protective sleeve is fixed to the outside of the overhead pipeline, ensuring the assembly stability of the outer protective sleeve layer.
[0017] In one or more embodiments of this utility model, the length of the tightening strap is the same as the length of the fixing strap, and both the tightening strap and the fixing strap are nylon ropes. This ensures the corrosion resistance and abrasion resistance of the tightening strap during use and improves the reliability of the tightening strap in assisting to fix the outer protective layer.
[0018] Compared with the prior art, the present invention discloses a segmented anti-corrosion protective sleeve for overhead pipelines. By setting up a set-type protective structure, it can provide segmented set protection for overhead pipelines, simplifying the anti-corrosion treatment process for overhead pipelines and improving the reliability and convenience of anti-corrosion protection for overhead pipelines.

[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0028] like Figures 1 to 5 As shown, in one embodiment of this utility model, the segmented anti-corrosion protective sleeve for overhead pipelines includes: an outer protective sleeve layer 1, Velcro 2, Velcro 3, and a pair of side binding straps 4. In practical applications, the outer protective sleeve layer 1 is segmented and fitted onto the outside of the overhead pipeline. The two long sides of the outer protective sleeve layer 1 are connected by the Velcro 2 and Velcro 3 adhering to each other. Simultaneously, the two ends of the outer protective sleeve layer 1 are bound together using the pair of side binding straps 4.
[0029] Specifically, the outer protective sleeve 1 is a rectangular component, including two long sides and two short sides. The anti-corrosion protective sleeve is fitted onto the outside of the overhead pipeline by arranging the two long sides along its outer edge. Compared to brushing, this application offers advantages such as comprehensive protection, no blind spots in the coating process, and ease of operation.
[0030] Preferably, the outer protective sleeve 1 is made of waterproof nylon fabric. It has good anti-corrosion and wear-resistant protective properties, improving the effectiveness of the outer protective sleeve 1 in protecting overhead pipelines.
[0031] like Figures 1 to 5 As shown, the Velcro 2 is fixedly connected to the outer side of one long side of the outer protective sleeve 1, and the Velcro 3 is fixedly connected to the other long side of the outer protective sleeve 1 and is compatible with the Velcro 2. Both the Velcro 2 and the Velcro 3 are sewn to the outer protective sleeve 1. This ensures the stability and ease of processing of the connection between the Velcro 2 and the Velcro 3 and the outer protective sleeve 1. By connecting the two long sides of the outer protective sleeve 1 through the mutual adhesion of the Velcro 2 and the Velcro 3, the ease of assembling and connecting the outer protective sleeve 1 is improved.
[0032] like Figures 4 to 5 As shown, an anti-corrosion inner layer 5 is fixedly connected to the inner side of the outer protective sleeve 1. The anti-corrosion inner layer 5 is made of epoxy resin composite material. The anti-corrosion inner layer 5 improves the anti-corrosion protection performance of the outer protective sleeve 1.
[0033] like Figures 4 to 5As shown, a protective liner 6 is fixedly connected to the inner side of the anti-corrosion inner layer 5. The protective liner 6 is made of fiberglass cloth. The installation of the protective liner 6 ensures the assembly and connection stability of the anti-corrosion inner layer 5 and improves the service life of the outer protective sleeve 1 and the protective liner 6.
[0034] It is worth noting that the transverse dimensions of the inner anti-corrosion layer 5 and the protective lining 6 are the same as the long side dimension of the outer protective sleeve 1, while the longitudinal dimensions of the inner anti-corrosion layer 5 and the protective lining 6 are smaller than the short side dimension of the outer protective sleeve 1. This allows the inner anti-corrosion layer 5 and the protective lining 6 to fit snugly against the outside of the overhead pipeline, reducing the possibility of gaps appearing due to overlapping of the inner anti-corrosion layer 5 and the protective lining 6, and further improving the reliability of corrosion protection for the overhead pipeline.
[0035] like Figures 3 to 5 As shown, a pair of side binding straps 4 are fixedly connected to the two short sides of the outer protective sleeve 1, respectively, for binding the ends of the outer protective sleeve 1.
[0036] Specifically, the pair of side elastic bands 4 are hollow components with openings at both ends. The side elastic bands 4 are made of waterproof fabric and are sewn to the short sides of the outer protective sleeve 1. By tightening the side elastic bands 4, the two short sides of the outer protective sleeve 1 are tightened and protected, thus improving the effectiveness of the sleeve protection for overhead pipelines.
[0037] like Figures 2 to 5 As shown, a fixing strap 7 is inserted inside the side drawstring 4, with both ends of the fixing strap 7 extending to the outside of the side drawstring 4. The side drawstring 4 is tightened and secured by tightening and binding the fixing strap 7.
[0038] like Figures 2 to 5 As shown, multiple sets of tension limiting rings 8 are fixedly connected to the outer side of the outer protective sleeve 1, with each set containing 3 to 6 tension limiting rings 8. The outer protective sleeve 1 is auxiliaryly bound by tensioning and limiting the multiple sets of tension limiting rings 8.
[0039] like Figures 2 to 5 As shown, the tension limiting ring 8 is an annular component with openings on both sides, and each set of tension limiting rings 8 has a binding strap 9 inserted inside. By binding the binding strap 9, the anti-corrosion protective sleeve is fixed to the outside of the overhead pipeline, ensuring the assembly stability of the outer protective sleeve layer 1.
[0040] It is worth noting that the length of the tightening strap 9 is the same as the length of the fixing strap 7, and both the tightening strap 9 and the fixing strap 7 are nylon ropes. This ensures the corrosion resistance and abrasion resistance of the tightening strap 9 during use and improves the reliability of the tightening strap 9 in assisting to fix the outer protective sleeve layer 1.
[0041] The specific working principle of this application is as follows:
[0042] First, based on the actual dimensions of the overhead pipeline, select a corrosion-resistant protective sleeve that matches the dimensions of the overhead pipeline. At the same time, based on the length of the overhead pipeline, select a different number of corrosion-resistant protective sleeves.
[0043] Subsequently, the operator moved the long side of the outer protective sleeve 1 circumferentially along the outside of the overhead pipeline, thus placing the outer protective sleeve 1 on the outside of the overhead pipeline. At this point, the short side of the outer protective sleeve 1 is cylindrical. Then, the two long sides of the outer protective sleeve 1 are connected using Velcro 2 and Velcro 3, achieving the initial placement of the anti-corrosion protective sleeve on the outside of the overhead pipeline.
[0044] Then, the two side binding straps 4 are tightened and bound by pulling and securing the binding straps 7, thereby sealing both ends of the anti-corrosion protective sleeve. Simultaneously, multiple binding straps 9 are used to further secure the anti-corrosion protective sleeve, improving its stability. After the sleeve is assembled, the overhead pipeline is protected against corrosion by the outer protective sleeve layer 1, the inner anti-corrosion layer 5, and the protective lining 6.
[0045] Subsequently, based on the actual situation, multiple anti-corrosion protective sleeves were respectively fitted onto the outside of the overhead pipeline to provide multi-segment anti-corrosion protection for the overhead pipeline.
[0046] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
