Description

Technical Field

[0001] This utility model belongs to the field of pipeline insulation technology, specifically a frost-proof insulation protective sleeve for rural water supply pipelines in mountainous areas. Background Technology

[0002] Currently, in rural water supply pipelines, especially those exposed outdoors, the antifreeze and insulation measures mainly rely on traditional insulation materials in plain areas, such as rock wool, glass wool, polyethylene foam, or rubber and plastic sponge. These materials are usually fixed and wrapped around the outer wall of the pipeline by means of wire, binding straps, or tape, and can play a certain role in insulation and antifreeze in plain areas with relatively stable climate and flat terrain.

[0003] However, when water supply pipelines are laid in mountainous areas with complex terrain and harsh environments, the pipelines often need to pass through areas with exposed rocks due to the large undulations in the terrain. Although traditional materials have a certain degree of flexibility, their puncture resistance and tear resistance are generally low. During installation and maintenance, the pipelines will inevitably rub, scrape, or even be squeezed by sharp gravel, exposed rock, branches, and other hard objects, which can easily scratch or puncture the outer surface of the soft insulation layer or cause damage to the internal structure, thereby destroying the integrity of the insulation structure and reducing the insulation performance. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a freeze-proof and heat-insulating protective sleeve for rural water supply pipelines in mountainous areas, thereby solving the problem that existing rural water supply pipelines laid in mountainous areas are easily damaged.

[0005] A protective sleeve for preventing freezing and heat preservation of rural water supply pipelines in mountainous areas includes a heat insulation and reflective layer, which is sleeved on the outside of the pipeline body. An insulation layer is provided outside the heat insulation and reflective layer, and a protective layer is provided outside the insulation layer. The heat insulation and reflective layer, the insulation layer and the protective layer are integrally formed by hot pressing and the cross-sectional outline is rectangular after the whole is unfolded.

[0006] It also includes a locking and sealing assembly that fixes the heat-insulating reflective layer, the heat-insulating layer and the protective layer to the outside of the pipe body.

[0007] Preferably, the heat-insulating reflective layer is a component made of composite aluminum foil, the heat-insulating layer is a component made of closed-cell cross-linked polyethylene foam, and the protective layer is a component made of flame-retardant PVC-coated fiberglass cloth.

[0008] Preferably, the heat-insulating reflective layer has a textured surface sticker on the side away from the heat-insulating layer and at its end position. The textured surface sticker is spaced apart along the length direction of the heat-insulating reflective layer. The outer wall of the protective layer has hook-shaped surface stickers spaced apart along the length direction. The textured surface sticker and the hook-shaped surface sticker cooperate with each other.

[0009] Preferably, the locking and sealing assembly includes a retaining ring assembly, a mating plate, a sealing pressure plate, and a sealing screw. The sealing pressure plate is movably pressed against the top of the outer wall of the protective layer. The top of the sealing pressure plate is provided with spaced pressing grooves. The retaining ring assembly consists of two semi-arc retaining rings. One end of the two retaining rings is rotatably connected by a shaft. The mating plate is fixedly connected to the end of the retaining ring away from the shaft.

[0010] Preferably, the vertical cross-sectional profile of the sealing plate is "L" shaped and is vertically fixed to the other end of the two retaining rings. The "L" shaped vertical sections of the two sealing plates are arranged opposite each other and are movably fitted together. The "L" shaped horizontal section of the sealing plate is inserted into the pressing groove. The sealing screws are symmetrically installed between the two sealing plates.

[0011] Preferably, a support ring is provided at the bottom of the pipe body and between the two retaining rings. The vertical cross-sectional profile of the support ring is semi-circular. The inner wall of the support ring is provided with a buffer layer that fits against the protective layer. The bottom wall of the support ring is provided with a vertical support rod, and the bottom of the support rod is provided with a base plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model features a pipe body with a heat-reflective layer attached to its outer wall to reflect heat radiation. The middle layer is an insulation layer made of closed-cell cross-linked polyethylene foam, which effectively insulates the pipe body and prevents it from freezing. The outermost layer is a protective layer made of flame-retardant PVC-coated fiberglass cloth, which is waterproof and protects the pipe body. In mountainous areas, it also prevents sharp stones and exposed rocks from rubbing against the protective sleeve, thus ensuring the insulation and antifreeze effect of water supply pipes in rural mountainous areas during winter.

[0014] 2. This utility model uses a heat-insulating reflective layer, a heat-insulating layer, and a protective layer to form an integral flexible heat-insulating sleeve structure through hot-pressing composite. This not only ensures a tight bond between the functional layers and prevents interlayer movement from affecting the heat insulation effect, but also its rectangular unfolded outline facilitates industrial mass production and on-site cutting and installation. It can tightly wrap the pipe body, effectively blocking the intrusion of external cold air in the frigid mountain environment, while minimizing the loss of heat from inside the pipe to the outside, and significantly improving the antifreeze and heat insulation performance.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1: This utility model provides a frost-proof and heat-insulating protective sleeve for rural water supply pipelines in mountainous areas, including a heat-insulating and reflective layer 2, which is sleeved on the outside of the pipeline body 1. A heat-insulating layer 3 is provided outside the heat-insulating and reflective layer 2, and a protective layer 4 is provided outside the heat-insulating layer 3. The heat-insulating and reflective layer 2, the heat-insulating layer 3 and the protective layer 4 are integrally formed by hot-pressing composite method and the cross-sectional outline after the whole is unfolded is rectangular.

[0024] It also includes a locking and sealing assembly, which fixes the heat-insulating reflective layer 2, the heat-insulating layer 3 and the protective layer 4 to the outside of the pipe body 1.

[0025] It should be noted that the heat-insulating reflective layer 2, the heat-insulating layer 3, and the protective layer 4 are combined by hot pressing to form an integral flexible heat-insulating sleeve structure. This not only ensures the tight bond between the functional layers and prevents interlayer movement from affecting the heat-insulating effect, but also its rectangular unfolded outline facilitates industrial mass production and on-site cutting and installation.

[0026] This structure can tightly enclose the pipe body 1, effectively blocking the intrusion of external cold air in the frigid mountain environment, while minimizing the loss of internal heat from the pipe body 1, and significantly improving the antifreeze and heat preservation performance.

[0027] In this embodiment, the heat-insulating reflective layer 2 is a component made of composite aluminum foil, the heat insulation layer 3 is a component made of closed-cell cross-linked polyethylene foam, and the protective layer 4 is a component made of flame-retardant PVC-coated fiberglass cloth.

[0028] It should be noted that the heat-insulating and reflective layer 2 made of composite aluminum foil can efficiently reflect the heat radiated outward from the pipe body 1, reducing radiative heat loss.

[0029] The insulation layer 3, made of closed-cell cross-linked polyethylene foam, has thermal insulation properties and a closed-cell structure. It has low water absorption and can maintain a stable low thermal conductivity for a long time, even in humid mountain environments, providing core insulation.

[0030] The protective layer 4, made of flame-retardant PVC-coated fiberglass cloth, provides excellent abrasion resistance, weather resistance, and flame retardancy. It effectively resists physical scratches, ultraviolet radiation, rain erosion, and accidental fire sources that may exist in mountainous environments, greatly extending the service life and safety of the protective cover. The three work together to form an efficient, durable, and safe antifreeze and heat insulation barrier.

[0031] In this embodiment, the heat-insulating reflective layer 2 is provided with a textured surface 5 on the side away from the heat insulation layer 3 and at the end position. The textured surface 5 is distributed at intervals along the length direction of the heat-insulating reflective layer 2. The outer wall of the protective layer 4 is provided with hook-shaped surface 6 distributed at intervals along the length direction. The textured surface 5 and the hook-shaped surface 6 cooperate with each other.

[0032] It should be noted that the textured adhesive 5 and hook adhesive 6 are spaced apart along the length. When wrapping the water supply pipe, the insulation sleeve is first unfolded to wrap around the pipe body 1. Then, the textured adhesive 5 on the heat insulation reflective layer 2 and the hook adhesive 6 on the outer wall of the protective layer 4 are aligned and pressed together. This design enables the insulation sleeve to close quickly and reliably at the overlapping part without the need for additional tools, which greatly improves the installation efficiency. It is especially suitable for working environments in mountainous areas where it is inconvenient to operate. At the same time, the spaced Velcro ensures that the overlapping area can also obtain good sealing and fit, preventing the overlapping part from forming a cold bridge due to lifting, which would affect the overall insulation effect.

[0033] In this embodiment, the locking and sealing assembly includes a retaining ring assembly, a mating plate 8, a sealing pressure plate 9, and a sealing screw 10. The sealing pressure plate 9 is movably pressed against the top of the outer wall of the protective layer 4. The top of the sealing pressure plate 9 is provided with spaced pressing grooves 11. The retaining ring assembly consists of two semi-arc retaining rings 7. One end of the two retaining rings 7 is rotatably connected by a shaft. The mating plate 8 is fixedly connected to the end of the retaining ring 7 away from the shaft.

[0034] It should be noted that the quick-locking assembly is clamped to the outside of the insulation sleeve by two semi-circular retaining rings 7. One end of the two retaining rings 7 is rotatably connected by a pin, which facilitates quick opening and closing of the sleeve on the pipe body 1.

[0035] The sealing pressure plate 9 is set at the top of the outer wall of the protective layer 4, i.e. at the overlap joint. The pressing groove 11 on it is designed so that after the two retaining rings 7 are locked on the outer wall of the protective sleeve, the two mating plates 8 enter into the pressing groove 11 and fit together, which increases the effective area and uniform force during compression, ensures that the insulation sleeve is tightly compressed, prevents loosening, and avoids displacement of the sealing pressure plate 9 in the later stage, thus improving the sealing performance of the protective sleeve installed on the pipe body 1.

[0036] In this embodiment, the vertical cross-sectional profile of the sealing pressure plate 9 is "L" shaped and is vertically fixedly connected to the other end of the two retaining rings 7. The "L" shaped vertical sections of the two sealing pressure plates 9 are arranged opposite each other and are movably fitted together. The "L" shaped horizontal section of the sealing pressure plate 9 is inserted into the pressing groove 11. The sealing screws 10 are symmetrically installed between the two sealing pressure plates 9.

[0037] It should be noted that the vertical section of the "L"-shaped sealing plate 9 is fixed to the end of the retaining ring 7 and fits together, while its horizontal section is embedded in the pressing groove 11 at the top of the retaining ring 7. When the sealing screw 10 is tightened, the two "L"-shaped vertical sections are pulled closer to each other, and at the same time, the "L"-shaped horizontal section moves downward in the pressing groove 11, thereby generating a uniform vertical downward pressing force on the insulation sleeve. This design cleverly transforms the tightening force of the screw into an effective sealing force on the insulation sleeve, enhancing the sealing effect at the overlap joint, effectively preventing cold air and moisture from entering from the overlap joint, and further strengthening the clamping effect of the retaining ring 7.

[0038] In this embodiment, a support ring 12 is provided at the bottom of the pipe body 1 and between the two retaining rings 7. The vertical cross-sectional profile of the support ring 12 is semi-circular. The inner wall of the support ring 12 is provided with a buffer layer 13 that fits against the protective layer 4. The bottom wall of the support ring 12 is provided with a vertical support rod 14, and the bottom of the support rod 14 is provided with a base plate 15.

[0039] It should be noted that the support ring 12 is located at the bottom of the pipe body 1. Its semi-circular inner wall is flexibly attached to the protective layer 4 of the insulation sleeve through the buffer layer 13. The buffer layer 13 is made of silicone pad material. On the one hand, the buffer layer 13 avoids the hard support ring 12 from directly compressing and damaging the protective layer 4. On the other hand, it can fill the small gaps and provide auxiliary sealing and shock absorption.

[0040] Meanwhile, the support rod 14, with its adjustable length via a screw thread, allows the pipe body 1 to maintain the required slope, facilitating drainage and freeze protection. The support base plate increases the ground contact area, preventing the support rod 14 from sinking into soft ground. This support structure provides stable support for the pipe body 1 and the protective sleeve, effectively preventing the pipe body 1 from sinking or deforming due to its own weight or external forces, ensuring uniform stress on the insulation sleeve, and is particularly suitable for uneven ground conditions in mountainous areas. Furthermore, it can lift the pipe body 1, thus avoiding direct contact with the ground and further preventing damage to the protective sleeve.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
