Abstract
Description
Technical Field
[0001] This application relates to the fields of materials science and engineering technology, and in particular to a steel wire skeleton pipe for urban water supply. Background Technology
[0002] As a core component of municipal infrastructure, urban water supply pipelines directly impact residents' water safety and urban operational efficiency. Traditional water supply pipelines must adapt to complex terrain and cope with the thermal expansion and contraction caused by seasonal temperature differences, placing stringent requirements on their structural stability and deformation compensation capabilities. Furthermore, pipelines face multiple challenges during long-term service, including soil pressure, mechanical vibration, and water pollution, demanding composite protective properties such as impact resistance, corrosion resistance, and self-cleaning capabilities.
[0003] In existing technologies, conventional water supply pipelines mostly adopt a fixed-length design, relying on flanges or expansion joints to achieve local deformation compensation. However, this type of structure has a limited adjustment range and its sealing performance is easily affected by repeated deformation, making it prone to joint leakage or even pipeline breakage when crossing undulating terrain or areas with severe temperature differences. Some improved solutions enhance deformation adaptability through corrugated pipe structures, but their compressive strength is significantly reduced, making it difficult to meet the pressure bearing requirements of the main water supply network. In terms of protection, ordinary pipelines mostly use a single material or simple coating, which is insufficient in buffering capacity against external impacts and lacks active protection mechanisms. This leads to the easy growth of microorganisms and the deposition of impurities on the inner wall of the pipeline, accelerating pipe wall corrosion and causing secondary pollution. Although composite pipes improve performance through multi-layer structures, the synergy between the functional layers is insufficient, and interlayer delamination is prone to occur under dynamic loads, which weakens the overall structural stability. Utility Model Content
[0004] In order to solve the problems mentioned in the background art, this application provides a steel wire skeleton pipe for urban water supply.
[0005] This application provides a steel wire skeleton pipe for urban water supply, employing the following technical solution: It includes a telescopic structure for extension and a protective structure for improving stability. A connecting block is fixedly connected to the outer side of the telescopic structure, and a circular pipe is fixedly connected to the outer side of the connecting block. A pipe is provided on the outer side of the circular pipe, and the protective structure is fixedly connected to the inner side of the pipe. The telescopic structure includes a pushing block, a sliding rod is fixedly connected to one side of the pushing block, a sliding groove is slidably connected to the outer side of the sliding rod, a slider is slidably connected to the inner side of the sliding groove, a support plate is slidably connected to the bottom of the slider, and a connecting groove is fixedly connected to the outer side of the support plate.
[0006] Optionally, the protective structure includes a composite layer, with a reinforcing layer fixedly connected to the inner first layer of the composite layer, a protective layer fixedly connected to the inner second layer of the composite layer, an adsorption layer fixedly connected to the inner third layer of the composite layer, and a support layer fixedly connected to the inner fourth layer of the composite layer.
[0007] Through the above scheme, the innermost reinforced layer of the composite layer in the protective structure can enhance the overall strength and toughness of the pipeline, making it more able to withstand external pressure; the innermost protective layer can effectively resist the corrosion of the pipeline by external physical and chemical factors; the innermost adsorption layer can adsorb impurities in the water and ensure water quality; and the innermost support layer provides stable support for the pipeline and prevents deformation.
[0008] Optionally, the composite layer is thermoplastic vulcanized rubber, the reinforcing layer is spandex, the supporting layer is a composite film, the protective layer is EVA foam, and the adsorption layer is silicone rubber.
[0009] Through the above scheme, the composite layer made of thermoplastic vulcanized rubber possesses good flexibility and sealing properties, while the reinforcing layer made of spandex enhances the pipe's pressure resistance. The support layer composed of a composite membrane provides stable support for the pipe and maintains its shape. The protective layer made of EVA foam effectively buffers external impacts, and the absorbent layer made of silicone rubber can absorb impurities in the water, preventing them from corroding the pipe.
[0010] Optionally, the thickness of the protective layer is 2mm-3.5mm, and the thickness of the composite layer is 1mm-2.5mm.
[0011] The above solution utilizes EVA foam with a thickness between 2mm and 3.5mm. The thicker foam provides better cushioning and shock absorption, effectively resisting external impacts, compression, and other physical shocks, protecting the pipeline from damage. The composite layer, made of thermoplastic vulcanized rubber with a thickness of 1mm to 2.5mm, enhances the overall sealing effect of the pipeline, preventing leaks, and also works tightly with other layers to extend its service life.
[0012] Optionally, the reinforcing layer has a thickness of 0.2mm-0.35mm, the adsorption layer has a thickness of 0.3mm-0.35mm, and the support layer has a thickness of 0.2mm-0.15mm.
[0013] The above-mentioned solutions, with a reinforcing layer thickness of 0.2mm - 0.35mm, significantly improve the overall pressure resistance of the pipeline, making it more resistant to external pressure. The adsorption layer, with a thickness of 0.3mm - 0.35mm, made of silicone rubber, effectively adsorbs impurities in the water, preventing corrosion and ensuring water quality and pipeline safety. The support layer, with a thickness of 0.2mm - 0.15mm, maintains the pipeline's shape and prevents deformation.
[0014] Optionally, a telescopic structure is fixedly connected to one side of the annular tube, and a pipe is provided inside the telescopic structure.
[0015] The above-described design allows the circular pipe to connect and transport water. Its fixed expansion joint on one side accommodates length changes caused by thermal expansion and contraction, ground settlement, and other factors during installation and use, preventing damage due to stress concentration. The pipe inside the expansion joint serves as the actual channel for transporting urban water, ensuring smooth flow through the entire water supply system.
[0016] Optionally, a reinforcing layer is provided on the outer side of the annular tube, and a supporting layer is provided on the outer side of the reinforcing layer.
[0017] The reinforcing layer installed on the outside of the circular annular pipe, as described above, significantly enhances its resistance to pressure and deformation, making it better able to withstand external pressure and complex environments. The supporting layer installed outside the reinforcing layer provides stable support for the circular annular pipe, preventing displacement or deformation due to external forces.
[0018] In summary, this application includes the following beneficial technical effects:
[0019] This utility model, through the setting of a telescopic structure, includes components such as a push block, a sliding rod, a sliding groove, a slider, a support plate, and a connecting groove. Through the cooperation between the push block and the sliding rod, sliding groove, and slider components, the telescopic structure can drive the sliding rod to slide in the sliding groove by moving the push block, and then drive the slider to slide on the support plate, thereby realizing the expansion and contraction function of the pipeline. It can solve the problem of insufficient or excessive pipeline length caused by factors such as terrain changes and thermal expansion and contraction during the laying and use of urban water supply pipelines, which affects the installation and use. Thus, it can adapt to different terrains and usage environments, and improve the flexibility of pipeline installation and use.
[0020] This utility model, through the setting of a protective structure including components such as a composite layer, a reinforcing layer, a protective layer, an adsorption layer, and a support layer, utilizes the interrelationship between the materials of each layer to ensure comprehensive protection of the pipeline. The composite layer completely envelops the pipeline, while the reinforcing layer enhances pipeline strength, the protective layer provides buffer protection, the adsorption layer absorbs impurities, and the support layer provides internal support. This comprehensive protection addresses issues such as external damage, water pollution, and pipeline deformation that urban water supply pipelines are susceptible to during use, thereby extending pipeline lifespan, ensuring water quality safety, and enhancing pipeline stability and pressure resistance.
