Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage construction technology, and in particular to a device for preventing collapse during water supply and drainage construction. Background Technology

[0002] In the construction of municipal engineering projects, the laying of water supply and drainage pipelines is a very important step. However, during the construction of municipal water supply and drainage pipelines, the pipelines are prone to collapse due to the influence of terrain and the length and weight of the pipelines themselves. Therefore, anti-collapse structures are needed to support and secure the pipeline joints.

[0003] The patent document with publication number CN221989497U describes a device for preventing collapse during water supply and drainage construction. It uses a protective plate to surround the outside of the pipe and fixes the mounting block with a threaded rod and nut to fix the protective plate to the pipe. A spring and pressure plate are set on the inner wall of the protective plate to prevent the pipe connection from falling off due to the impact of collapse.

[0004] The document describes using protective plates to enclose the pipeline, which improves the circumferential tightness between the protective plate and the pipeline. However, the lack of internal limiting structures within the protective plate means that it can easily shift axially when the pipeline is impacted, affecting the stability of the enclosure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where protective plates are prone to shifting along the axial direction of the pipeline, and to propose a water supply and drainage construction anti-collapse device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a water supply and drainage construction anti-collapse device, including a pair of sheaths, the sheaths being fitted over the outside of a water pipe, a flange of integral structure being fixedly installed at the end of the water pipe, and an integral edge structure being fixedly installed on both sides of the sheaths, with bolts threaded inside the edge structure, and anti-loosening nuts threaded at the ends of the bolts, a snap-fit ​​groove being provided inside the sheath, the flange fitting inside the snap-fit ​​groove, and a groove being provided on the inner wall of the sheath, with a buffer element snapped in the groove.

[0008] Preferably, a rubber sheet is provided between the edges.

[0009] Preferably, a rubber sleeve is fixedly bonded to the inner wall of the snap-fit ​​groove, and the rubber sleeve abuts against the outer surface of the flange.

[0010] Preferably, the cushioning element is made of polyurethane foam.

[0011] Preferably, an integrally formed protrusion is fixedly installed on the inner surface of the buffer member, and multiple protrusions are provided and evenly distributed along the axial direction of the buffer member.

[0012] Preferably, the inner wall surface of the sheath is provided with a first buckle groove and a second buckle groove. The first buckle groove is located on one side of the snap-fit ​​groove, and a first washer is snapped in the first buckle groove. The second buckle groove is located on the inner side of the end of the sheath, and a second washer is snapped in the second buckle groove.

[0013] Preferably, one side of the first gasket extends into the snap-fit ​​groove and abuts against the side of the flange, and one side of the second gasket extends to the outer side of the sheath end.

[0014] Preferably, the interior of both the first and second washer rings is made of elastic rubber.

[0015] The present invention proposes a water supply and drainage construction anti-collapse device, which has the following advantages: When in use, the device can greatly improve the stability of the connection between the sheath and the water pipe in the axial direction by the cooperation of the flange and the snap-fit ​​groove. The device can improve the stability of the connection between the sheath and the water pipe in the circumferential direction by fixing the edge with bolts and anti-loosening nuts. The device can absorb the stress generated by the impact of external force on the end of the water pipe through the protrusion and the buffer, and prevent the joint from loosening and collapsing due to impact.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A collapse prevention device for water supply and drainage construction includes a pair of sheaths 1. The sheaths 1 are fitted over the outside of a water pipe 100. An integral flange 200 is fixedly installed at the end of the water pipe 100, and the joint of the water pipe 100 is connected to bolts via the flange 200. The sheaths 1 are semi-circular tube structures. Integral edge strips 2 are fixedly installed on both sides of the sheaths 1. Bolts 4 are threaded inside the edge strips 2, and anti-loosening nuts 5 are threaded at the ends of the bolts 4. The bolts 4 and anti-loosening nuts 5 secure the edge strips 2, facilitating the splicing and fixing of the sheaths 1. A rubber sheet 3 is provided between the edge strips 2 to improve the sealing between them, preventing external water and dust from entering the sheaths 1.

[0023] The sleeve 1 has a snap-fit ​​groove 6 inside, and the flange 200 fits into the snap-fit ​​groove 6. The snap-fit ​​groove 6 can fix the position of the flange 200 and tighten the sleeve 1 and the water pipe 100 in the axial direction, preventing the sleeve 1 from moving in the axial direction of the water pipe 100. A rubber sleeve 7 is fixedly bonded to the inner wall of the snap-fit ​​groove 6. The rubber sleeve 7 abuts against the outer surface of the flange 200. The rubber sleeve 7 can improve the sealing performance of the connection between the flanges 200, and can provide a final sealing protection from the inside, preventing impurities from entering the water pipe 100, and also preventing the medium inside the water pipe 100 from leaking out.

[0024] The inner wall of the sheath 1 has a groove 12, and a buffer element 13 is snapped into the groove 12. The groove 12 prevents the buffer element 13 from shifting within the sheath 1. The buffer element 13 is made of polyurethane foam, or it can be made of nitrile rubber, which has high elasticity and corrosion resistance. It is mainly used to enhance the buffering effect between the sheath 1 and the water pipe 100, and can absorb the impact stress at the joint of the water pipe 100, thus providing good protection. An integral protrusion 14 is fixedly installed on the inner surface of the buffer element 13. Multiple protrusions 14 are provided and evenly distributed along the axial direction of the buffer element 13, providing sufficient buffering space for the entire buffer element 13.

[0025] Working principle: When using this anti-collapse device for water supply and drainage construction, the sheath 1 is placed on the outside of the water pipe 100 joint, and the flange 200 is fitted into the snap-fit ​​groove 6 to enhance the axial stability between the sheath 1 and the water pipe 100. The gap between the flange 200 is wrapped by the rubber sleeve 7 to prevent the medium inside the water pipe 100 from seeping out. The edge 2 is fixed by bolts 4 and anti-loosening nuts 5, so that the inner wall surface of the sheath 1 is in close contact with the outer wall surface of the water pipe 100, enhancing the circumferential stability between the sheath 1 and the water pipe 100. The protrusion 14 abuts against the outer side of the end of the water pipe 100. When the water pipe 100 is subjected to external impact, the protrusion 14 and the buffer 13 absorb the impact stress of the end of the water pipe 100, playing a protective role and preventing the water pipe 100 joint from loosening and collapsing.

[0026] Example 2: In Example 1, although the rubber sheet 3 can improve the sealing between the edges 2, there is a risk of leakage at the connection points between the two ends of the sheath 1 and the outer wall of the water pipe 100. Therefore, this example is proposed. (Refer to...) Figure 1 In another preferred embodiment of this utility model, based on embodiment 1, a first snap groove 8 and a second snap groove 10 are provided on the inner wall surface of the sheath 1. The first snap groove 8 is located on one side of the snap groove 6, and a first washer 9 is snapped in the first snap groove 8. The first washer 9 can improve the sealing of the inner side of the sheath 1 and prevent leakage at the joint of the water pipe 100. The second snap groove 10 is located on the inner side of the end of the sheath 1, and a second washer 11 is snapped in the second snap groove 10. One side of the first washer 9 extends into the snap groove 6 and abuts against the side of the flange 200, and one side of the second washer 11 extends to the outer side of the end of the sheath 1. The first washer 9 and the second washer 11 are both made of elastic rubber. The second washer 11 can improve the sealing of the connection between the end of the sheath 1 and the outer wall of the water pipe 100 and can prevent external impurities from entering the interior of the sheath 1.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
